INVENTORS WILLIAM E. WHITE THERON F. BRENNEMAN United States Patent This invention relates to building panels and is more particularly concerned with improvements in a precast or molded wall panel having incorporated therein a fixed window.

It is a general object of the invention to provide a wall panel for building structures wherein the panel is initially formed with a window opening having a window frameof metal or other rigid material which is embedded in the panel around the periphery of the opening and which is adapted to receive in permanently mounted relation therein a single pane of glass or a multiple pane glass unit.

It is a more specific object of the invention to provide a building wall panel of precast or molded material, for example, concrete, having a window opening and a metal window frame embedded in the concrete about the periphery of the opening and adapted to receive a pane of glass or a multiple pane glass unit with its margins encased in rubber-like glazing elements which are held under compression by glazing clips wedged between a portion of the frame and the glazing elements.

It is a still more specific object of the invention to provide a wall panel construction wherein a precast or molded panel of concrete or similar material is provided when it is formed with a window opening having an edge facing in the direction of the center of the opening and a metal window frame embedded therein with the frame being formed to provide a glazing channel in which a pane of glass having its margins sandwiched between a pair of rubber-like glazing elements is adapted to be seated and held in fixed position therein by a plurality of peripherally spaced rigid glazing clips seated in a recess spaced inwardly of the glazing channel, which glazing clips are constructed so as to exert pressure against the inner face of the innermost glazing element and hold the glazing elements permanently compressed.

It is another object of the invention to provide a precast concrete panel having a metal window frame embedded in the peripheral portion of a window opening therein which frame is adapted to receive a pane of glass with its margins seated in a glazing channel formed in the frame and with a pair of rubber-like glazing strips encasing the margins of the glass pane which are placed under compression by the installation of rigid metal clips, with the clips being shaped so that they may be wedged between a portion of the frame and a rigid glazing bar which engages with the innermost one of the glazing strips.

These and other objects and advantages of the invention will be apparent from a consideration of the several panel constructions which are shown by way of illustration in the accompanying drawings wherein:

FIGURE 1 is an elevation with portions broken away of a precast concrete panel having a fixed window which incorporates the principal features of the invention, the view showing the inside face of the panel;

FIGURE 9 is an exploded perspective view showing the panel of FIGURE 8 and the window forming elements;

FIGURES 10 and 12 are cross sections similar to FIG- URES 2 and 3 illustrating still another modification of the panel; and

FIGURE 11 is a view taken on the line 11-11 of FIG URE 10.

Referring to FIGURES 1 to 5 of the drawings, particularly, there is illustrated a building wall unit embodying the invention which comprises a panel 10 of precast concrete having a window opening 11 of fixed dimensions therein and a metal window frame 12 solidly embedded in the peripheral wall surface 13 which defines the opening 11.

The metal frame 12 is formed prior to the casting or molding of the panel so that when the frame is glazed the head and the jamb have a cross section as shown in FIG- URE 2 while the sill has a cross section as shown in FIG- URE 3. All four sides of the frame 12 may be formed by bending relatively .thin metal plate, preferably stainless steel or aluminum, or all four sides of the frame may be sections of a continuous metal extrusion, such as alumi- The head and jamb forming sections 14 and 15 of the frame 12 and the sill forming section 16 may each be separate pieces mitered or otherwise joined at the corners of the opening 11. As shown in FIGURE 2, frame sections 14 and 15 are formed with an outer wall 17 and a parallel inner wall 18, both extending generally in the plane of the opening 11. The edges of the two walls 17 and 18, in the direction outwardly of the opening 11, are connected by a wall 19 which is bent or shaped to form an inwardly projecting rib 20 of U-shaped cross section. The rib 20 islocated between the frame walls 17 and 18 so that it cooperates with the latter to provide a glazing channel 21 adjacent the outer frame wall 17 and a relatively narrow channel-like slot or recess 22 adjacent the inner frame wall 18. The glazing channel 21 and the slot 22 are separated by the inner wall section 23 of the rib formation 20, the later extending inwardly approximately half the depth of the frame walls 17 and 18. The frame walls 17 and 18 have their inner edges bent over to provide oppositely directed narrow flanges 24 and 25 and the frame sections are embedded in the material of the panel 10 with the edge flanges 24 and 25 flush with the inner edge or wall 13 of the opening.

The sill or bottom section 16 of the frame 12, as shown in FIGURES 3 and 4, is formed in two parts or members 26 and 27 with the former embedded in the material of the panel and the latter forming a removable insert. The main par-t 26 of the frame section 16 comprises angularly related vertically and horizontally disposed wal-l members 28 and 29 with the edges of these members having narrowhorizontal and vertical flanges 30 and 31 along their free edges. The main frame member 26 is embedded in the panel edge 13 with the flange 30 of the vertical wall 28 flush with the edge of the opening'and with the vertically disposed flange 31 of the horizontal wall 29 terminating at a sill forming surface 32 which is slightly above the plane of the horizontal wall 29 and well below the plane of the panel opening defining edge L) 13, this arrangement being provided to facilitate the glazing of the frame after the panel is installed in the building. The horizontal wall 29 is provided with a series of spaced tongues 33 which are cut from the wall and bent upwardly as shown in FIGURES 3 and 4 so as to provide spaced anchoring points for the insert forming member 27 of the frame section 16 when the member 27 is assembled with the frame member 26.

The insert member 27 is bent or otherwise shaped to provide, when assembled with the frame member 26, an outer vertical wall 34 of approximately half the height of the wall 28 and an inner vertical wall 35 of the same height, with the two walls extending in opposite directions. Between these two walls the plate is shaped to provide an inwardly extending rib forming portion 36 which corresponds to the rib formation (FIGURE 2) and two relatively narrow groove formations or slots 37 and 38 which are located adjacent the inner wall and separated from the outer wall 34 by the horizontal wall 39. The outer wall 34 is provided at its free edge with a relatively narrow flange 40 and the insert 27 is adapted to be connected with the frame member 26 by inserting the flange 40 beneath the tongues 3-3 on the horizontal wall 29 and springing the member to snap the inner margin of the inner wall 35 into engagement with the flange 31 on the horizontal wall 29 so that the insert 27 is seated on the horizontal wall 29 as shown in FIGURE 3 and the outside wall 34 is spaced from the wall 28 of the main frame member 26 so as to provide the bottom portion 21' of the glazing channel 21 in the head and jamb. The panel 10 is adapted to be cast with the sections 14, 15 and 16 of the frame in position so that they are embedded in the concrete material, except for the insert forming member 27 of the sill which is installed during the glazing of the frame. Anchor members, in the form of angle brackets 41, may be attached to the outside faces of the frame so as to be embedded in the adjoining material of the panel at the time of the casting thereof.

The window frame 12 is adapted to be glazed before or after the panel is mounted in its permanent position in the building. A glass pane 42 is positioned in the glazing channel 21, 21' with its margins encased in outer and inner glazing strips 43 and 44 which are formed of rubber-like resilient and compressible material, for example, rubber or neoprene. The glazing elements 43 and 44 may be formed, of course, as a continuous strip of U-shaped cross section, if desired. The glass pane 42 is of a size sufiicient to permit it to be seated in the glazing channel 21, 21' with the outermost glazing strip 43 having its inner edge facing in the direction of the center of the opening and substantially flush with the edge surface 13 of the opening. The pane 42 is supported on shim forming blocks 45 seated in the bottom portion of the glazing channel. A rigid glazing strip 46, of relatively thick metal, for example, aluminum, is seated on the inner faces 23 and 39 of the rib formations 20 and 36 about the periphery of the pane 42 in face engaging relation with the inner surface of the innermost glazing strip 44 and this rigid glass retainer strip is permanently locked in position by a series of peripherally spaced fastener or clamping members 47. The clamping members 47 are preferably in the form of short sections of extruded aluminum or similar metal having a plate-like leg form ing portion 48 and a top or head portion 50 which is in a plane parallel to but offset somewhat from the leg portion 48. The clamping members 47 are shaped so that when installed as shown in FIGURES 2 and 3, with the leg portion 48 in the groove or solt 22 of the jamb and head portions of the frame and the slot 37 of the sill portion 16 of the frame, the vertical face 51 of the head portion 50 will engage against the inside face of the rigid metal glazing strip 46. The clamping members 47 are proportioned so that when they are installed by forcing the leg forming portion 48 into the slot 37 in the frame,

pressure is applied to the rigid glazing bar member 46 suflicient to compress the rubber glazing strips 43 and 44, thereby to clamp the glass pane 42 in the glazing channel and hold the same permanently in position. A cover or trim strip 52 is provided for covering the glazing bar 46 along the head and jamlb. The strip 52 may be formed of bent plate such as stainless steel or aluminum or it may be an extrusion. It is formed with a main wall providing an inwardly facing surface 53 and a curved integral flange 54 which is adapted to be seated in a recess 55 formed between the head portion 50 of each clamping member and the inner wall 18 of the frame. The free marginal portion of the main wall 53 of the trim strip is bent at 56 so that it snaps over the outermost edge of the rigid glazing bar 46 to hold the trim strip 52 with its edge forming face 53 substantially flush with the surface of the edge 13 of the opening 11. At the bottom of the window a trim strip 57 is provided for the sill which may be shaped or formed of bent plate metal or the like, to provide an inwardly facing vertical wall 58 with a headlike flange 59 on its lower edge and a horizontally disposed, angularly related edge forming wall 60 with the latter having its marginal edge bent at 61. The trim strip 57 is adapted to have the marginal portions of the wall 58 seated in the slot 38 in the frame insert 27 and the bent edge 61 snapped over the outermost edge of the metal glazing bar 46 to cover the bar 46 and retain the trim strip in position.

A modified form of the panel structure is shown in FIGURES 5 and 6. In this form the panel 70 has a window opening 71 which is provided at its innermost edge with a fixed window frame 72, of extruded aluminum, stainless steel or other rigid material. The frame 72 is embedded in the panel 70 when the panel 70 is initially formed or cast. Since the frame 72 is set in the corner of the opening 71 in this form of the panel, the frame head, sill and jamb forming portions may be of identical construction, all having the cross section illustrated in FIGURE 5 and extending in the same manner around the periphery of the opening 71.

The frame 72 comprises an outer or vertical wall 73 which faces toward the inside of the panel and an angularly related, horizontal wall 74 which faces toward the center of the opening 71. A diagonal anchoring flange or plate member 75, which is embedded in the panel body, extends from the juncture of the two wall members 73 and 74. The wall 74 has on its inner marginal edge a peripherally extending portion of generally U-shaped cross section 76 which is constructed so as to form a slot-like recess 77 opening inwardly in the direction of the center of the window opening 71 and having the oppositely disposed inner surfaces of the walls 78 and 78 which define the sides of the slot 77 extending at a slight angle to the wall 73 of the frame. The outermost face of the wall 78 abuts the innermost face 79 of the panel 70.

The two angularly related walls 73 and 74 form a glazing channel or recess for receiving a glass pane 80 and an associated glazing assembly 81. The glazing assembly 81 comprises a pair of rubber-like glazing strips 82 and 83 which engage the margins of the pane 89 which is seated in the glazing channel on a block or shim 84, the latter being provided to support the pane in proper position relative to the edges of the opening 71. A rigid metal glazing bar 85 is provided which is seated on the wall member 74 and bears against the innermost glazing strip 83. The rigid glazing bar 85 is held in position when the pane 80 is installed by a plurality of peripherally spaced fastening and clamping devices 86. Each of the fastening and clamping devices 86 is shaped so as to provide a plate-like flange or stem fonming portion 87 which is adapted to be seated in the groove or slot 77 in the frame and a plate-like head forming portion or flange 88 which is in a plane generally parallel to and offset relative to the plane of the stem forming portion 87 and which is adapted to be forced into face engagement with the innermost face 89 of the rigid glazing bar 85. The fastening and clamping devices 86 are so proportioned that when the stem 87 thereof is seated in the frame recess 77 the head 88 of the device is forced against the glazing bar 85 with substantial pressure so as to permanently compress the glazing strips 82 and 83 and rigidly clamp the glass pane 80 in the glazing channel.

A trim strip 90 is provided for covering the protruding portions of the frame and the glazing bar 85 whichis generally U-shaped -in cross section with a vertical inside face 91 and inner and outer edge faces 92 and 93; the latter terminating at the free edges in bent over flange forming portions 94 and 95 which snap over cooperating beveled edges 96 and 97 on the glazing bar 85 and the innermost frame member 76, respectively.

A further modified form of the panel is shown in FIGURES 7 to 9 of the drawings. In this form the panel 100 has a window opening 101 with a rigid metal window frame 102 embedded in an inner peripheral edge 103 extending between the inside and outside surfaces of the panel. The panel 100 is similar to panel with the rigid metal window frame formed of extruded metal, such as aluminum.

The head and jamb forming portions or sections 104 and 105 (FIGURE 7) of the frame 102 are constructed so that when the frame is glazed the head and jamb have a cross section as shown in FIGURE 7, while the sill forming section 106 is formed so that it has the cross section shown in FIGURES 8 and 9. The head and jamb forming frame sections 104 and 105 have a generally U-shaped cross section providing an outer or outside wall 107, an inner or inside wall 108 and a connecting peripheral edge forming wall or web 109 connecting the outer edges of the outer and inner wall members 107 and 108. The outer and inner wall members 107 and 108 are parallel and extend generally in the plane of the opening 101. An inwardly extending rib forming member 110 on the edge wall 109 has its inner edge bent over to form a supporting flange at 111 and divides the space between the walls 107 and 108 into a glazing channel 112 and a slot-like fastener receiving recess 113 adjacent the inside wall 108. The rib forming member 110 extends inwardly approximately half the depth of the frame section. The edge wall 1.09 is provided with a T-shaped outwardly extending flange 114 which is embedded in the material of the panel so as to further anchor the frame members.

The sill or bottom forming section 106 (FIGURES 8 and 9) of the frame 102 is formed in two parts or members 115 and 116 with the member 115 embedded in the material of the panel and the member 116 forming a removable insert. The main member 115 comprises angularly related, vertical and horizontally disposed wall members 117 and 118, the free edge of the latter having a narrow hook forming flange formation 120 which terminates flush with an inner edge portion 121 of the panel adjacent the opening 101. The member 115 is embedded in the panel 100 so that the free edge of the wall member 117 terminates flush with the edge 103 which defines the opening 101. The horizontal wall 118 is provided with an inwardly extending rib formation 122 which provides anchoring points for the insert forming member 116 when the member 116 is assembled with the main frame member 115. The insert member 116 is shaped to provide, when assembled with the frame member 115, a vertical, outwardly facing wall 123 which is approximately half the height of the adjacent wall 117 which it faces and a parallel, inwardly facing wall 124 which is slightly less than the height of the wall 117. The two Walls 123 and 124 extend in opposite directions and the wall 123 is provided with a narrow edge flange 125 which is adapted to hook beneath the abutment form ing rib 122. The two walls 123 and 124 are separated by an S-shapedconnecting wall 126 so as to form a slot or groove 127 adjacent the inside wall 124. The outside wall 123 cooperates with the oppositely disposed wall 117 to form the glazing channel 112'. The horizontal wall 118 of the main frame section is'pro vided with a T-shaped, outwardly extending flange 128 of the same character as the flange 114 and also for anchoring purposes.

The window frame 102 is adapted to be glazed before or after the panel 100 is mounted in its permanent position in the building. The glass pane 130 is positioned in the glazing channel 112 and 112 with its margins extending between inner and outer glazing strips 131 and 132 which are formed of rubber-like resilient and compressible material, such as, rubber or neoprene. It issupported on blocks 133 of wood or other suitable material, placed in the bottom of the sill section 115 of the frame 102. A rigid glass retaining glazing bar 134, preferably formed of aluminum or like material, is seated against the innermost face 135 of the glazing strip 132 on the flange 111 of the rib formation 110 of the head and jamb sections and the uppermost wall 136 of the insert member 116 in the sill section. The glazing bars 134 are clamped in position by a plurality of clamping and fastening devices 137. Each of the clamping and fastening devices 137 comprises two plate-like portions 138 and 139 which form the stem and head thereof and which are in parallel offset planes, being connected by an angular portion 140. The clamping and fastening devices 137 are installed by inserting the stem portion 139 in the slots 113 and 127 and forcing the top or head portion 138 into tight engagement with the innermost face 141 of the glazing bar 134. The clamping and fastening devices 137 are proportioned so that when installed as shown in FIGURES 7 and 8 pressure is applied to the glazing bar 134 which is sufficient to permanently compress the glazing strips 131 and 132 sufficiently to rigidly retain the glass pane 130 in the glazing channel. A cover strip 142 of generally T-shaped section is employed to complete the assemblyof the head and jamb and also the sill section of the frame. The stem portion'143 of the cover strip is frictionally engaged between the fastening devices 137 and the inside wall members 108 and 124 while the outside edge is bent at 144 to seat on the tapered or beveled outside edge 145 of the glazing bar 134.

Still another form of the panel is shown at in FIG- URES 10 to 12. In this form the panel has a window opening 151 which is provided at its edge and intermediate the inner and outer faces of the panel with a fixed window frame 152 embedded in the panel 150 when the panel is initially cast. The head and jamb forming portions of the frame are of identical construction while the sill section is modified to enable the window to be glazed. The frame 152 is formed of bent metal plate, such as aluminum or stainless steel, with the head section which is indicated at 153 having the cross section shown in FIGURE 10 and the sill section which is indicated at 154 having the cross section shown in FIGURE 12. The entire frame is cast in the panel so that its inner peripheral surface in the direction of the center of the opening 151 is flush with the inner edge surface 155 of the opening 151. The panel is formed with an inner recessed portionat the sill which has the surface 156 extending from the inside face of the panel to the sill section 154 so as to permit a pane of glass 157 to be inserted in the frame for the glazing operation before or after the panel is installed in the building wall.

The head forming frame section 153 has a generally U-shaped cross section providing a double ply outside wall 158 and a parallel inside wall 160, both of which extend The sill forming section 154 of the frame 152 is also bent to form a generally U-shaped cross section with a double ply outside wall 163, a shorter inside wall 154 and a connecting edge wall 165. The outside wall 163 is formed in the same manner as the outside wall 153 with an extended marginal portion 162 forming an anchorage member. The top edge of the inside Wall 164 terminates at the surface 156 and the outer edge forming wall 165 is provided with a series of longitudinally spaced, bent up or bent in tongues 166 which form an outer abutment or anchorage for an insert member 167. The insert member 167 has a bottom forming flange 168 which is adapted to be engaged beneath the tongues 166 and a reversely bent portion of inverted, generally V-shape in cross section providing an upstanding wall forming flange 170 and a downwardly and inwardly slanted wall member 171 having a hook-shaped foot 172 which abuts against the inside surface of the wall 164 at the juncture of the latter with the edge wall 165. The walls 163 and 170 which are substantially parallel cooperate to form with the edge wall 165 a glazing channel 173 in the sill forming section 154 which is a continuation of the glazing channel 173 formed between the outside and inside walls 158 and 169 of the head and jamb sections (FIGURE along the other three sides of the frame 152.

A shallow groove 174 is provided in the margin of the inside wall of the head and jamb sections for receiving an edge of a fastening device 175. The wall of the insert 167 in the frame section 154 is provided with a like groove or recess 176 for accommodating fastener members 175. The pane 157 with its edges encased in glazing strips 177 and 178 of resilient and compressible material, such as rubber, neoprene or like material, is inserted in the glazing channel 173, 173 and supported on blocks 18%) of suitable material which are placed in the sill section 154 as shown in FIGURE 12. A rigid metal glazing bar 131 having a shallow groove or recess 182 on its inside surface is positioned against the inner face 183 of the innermost compressible glazing strip 178 and the glass and glazing assembly is clamped into position by installing a plurality of peripherally spaced clamping and fastening devices 175.

The clamping and fastening devices are in the form of rectangular plate members of metal or other rigid material having rounded corners 184 and a tool receiving slot 185 which is adapted to accommodate the blade of a screwdriver or similar tool. The fastening devices 175 have a dimension in the one direction which is somewhat greater than the normal distance betweenthe grooves 174 and 182 in the head jamb sections and the grooves 176 and 182 in the sill section so that the clamping and fastening devices may be inserted, as indicated in dotted line position in FIGURE 11, and rotated in the plane thereof to seat the ends in the grooves 174, 182 and 176, 182, leaving the devices installed with the glazing strips 177 and 178 compressed so as to firmly hold the pane 157 in fixed and sealed relation in the frame.

A cover or trim strip 186 (FIGURES 10 and 11) is provided to complete the frame assembly along the head and jamb sections. The marginal portions of the trim strip 186 are bent inwardly and then outwardly into parallel relation so as to form two marginal flanges 187 and 188 which are offset inwardly of the edges of the body of the strip and which fit into the glazing channel 173' between the inside wall 160 and the innermost face of the glazing bar 181, the flanges 187 and 188 being cut out to clear the clamping and fastening elements 175 where they are positioned. The glazing bar .181 is positioned with its inner edge face offset inwardly of the surface 155 of the opening so as to accommodate the one edge of the trim strip 186 while the inside wall 160 is formed with the marginal pocket 190 to accommodate the other edge of the trim strip 186 whereby the inside surface of the trim strip is fiush with the surface 155.

A trim strip 191 is provided for the sill section which has a relatively deep flange-like inner wall forming portion 192 with its marginal edge seated in the recess between the inside wall 164 of the frame section 154 and the wall forming portion 171 of the insert 167. At its other edge the trim strip 191 is reversely bent and provided with a flange 1% so as'to seat on the glazing bar 181 with the flange 193 extending along the inside surface of the latter. The flange 193 is cut out where required to clear the clamping and fastening devices 175.

While a single pane of glass is shown in all of the illustrated forms of the window, it will be understood that in each of the forms thereof the window frame may be glazed with .a multiple pane glass unit. Also, while the panel in each of the forms is described as formed of concrete, it may be cast or molded of other suitable material.

While particular materials and specific details of construction are referred to in describing the several forms of the panel which are illustrated, it will be understood that other materials and equivalent details of construction may be resorted to within the spirit of the invention.
