BUILDING CONSTRUCTION Y Application led October 11, 1927.

This invention relates to building construction and pertains more particularly to methods of forming concrete wall sec-tions having the external appearance of masonry or brick walls of the usual character, and capable of supporting the loads to which such walls are ordinarily subjected, but formed in such manner as to reduce the expense which is usually incidental to the making of masonry or brick walls by usual methods.

In building construction 1t is common practice to build walls of brickwork or masonry by laying the bricks or stones unit by unit with careful attention to plumbing as the wall is erected in order that the wall ma lie in a true vertical plane when complete This time honored method of construction involves the exercise of great skill in order that the finished wall may be straight and true, and skilled Workmen must be employed to Aperform the labor.

ccording to the present invention it is proposed to form members or sections of wall of substantial size on the ground, or on any level surface which may be provided for the purpose, which said members may then be hoisted in place either by hand or by suitable machinery to form a part of the Wall under construction. The said sections may have the external appearance of masonry or brickwork, or a combination of the two, and may be designed to have the requisite strength to support the stresses to which they may be subjected. It is also proposed to form the said sections in such manner that after they are set into place, abutting sections may be so treated as to conceal the line therebetween, so that the external appearance of the finished wall may present an unbroken appearance similar to the appearance of a wall constructed by the usual methods.

Two facing materials will be described herein in detail, namely, stone and brick, in order that the principles underlying the invention may be thoroughly understood, although it will be understood that other facing materials may be employed in the same manner if desired. .For 'purposesl of conven- 100 ience, the method will first be described with respect to stone and then with respect to brick.

Y Referring to Figures 1, 2, 3 and 4, a framework 1 may be provided of any desired length and width and of a de th sufficient to provlde a wall of the desired t ickness. Said frame work need not be provided with a bottom, as it may be conveniently laid upon any fairly levelpiece of ground. After the framework is constructed a layer of comminuted material such as sand is laid within the framework to a suitable depth, as for example, 3 or 4", and then upon this-layer is laid a layer of stone of which it is desired to form the face of the section. The separate pieces of stone may be laid fairly closel together and if necessary may be cut or bro en to provide the desired shapes and sizes. In laying the layer of stone, the separate pieces may be caused to embed themselves in the layer of sand to a depth equal to that which itgfis desired to have the stones project in the 'finished member. R'eenforcing bars 3 may then be laid in place, if desired, and a layer of concrete is then poured into the framework to cover completel the layer of stone. As will be observe the concrete penetrates the interstices between the stones as far as the layer of sand which serves to protect the front faces of the stones. If desired, suitable eyes 4 ma be embedded in the concrete toaid in han ling the finished section and to serve as an anchoring means. For example, as illustrated in Figure 9, a bolt 4 may be secured between two eyes to hold a section in desired position. If desired, the section may also have embedded therein at any desired position short sections of pipe 5 which may serve to receive dowel pins 6 to anchor the members to a fixed support such as a water table. If desired, wooden blocks 7 may also be embedded in the uper surface of the concrete to serve as suraces to which lath may be nailed.

Referring to Figures 6, 7 and 8, if desired, in order to furnish a convenient means of securing abutting members together, the sides of the framework 1 may have secured thereto longitudinally extendin blocks 8 which form grooves in the nature o keyways in the sides of the members so that when the members are placed together in the manner shownin Figure 8 the grooves may be filled with rout 9 thus bonding the members securely an forming, in effect, a solid wall. In order that the completed member may be easily removed from the surroundin framework, the framework may be forme in two or more sections which are pivotally connected as by the hinges 10 and which may be held together at the opposite corner by the pin 11.

In order to provide an external appearance of uniformity at the points where abutting members are joined, it has been found desirable to treat the sections in a manner which permits overlapping stones to be inserted after the sections have been set into place. Accordingly, during the formation of the member, certain of the stones alon the edge of the member which is to be joine to an adjacent member are surrounded with a layer of sand, in the manner illustrated in Figure 4, in order that when the concrete is poured the said stones may be separated from the concrete and will notbe bonded thereto as the concrete sets. As illustrated in Figure 4, alternative stones have been thus surrounded with a layer of sand, although it is to be understood it may be sufficient to treat a less number in this manner with good results.

As will be observed, after the concrete is set the member may be removed from the surrounding framework and the sand in which the stone was embedded will drop away leaving a stone surface closely resembling a masonry wall built by usual methods. At the same time the stones which have been surrounded by the extra layer of sand will also drop out of place leaving the voids 12 which are illustrated in Figure 12. As illustrated in Figure 13, when the members are placed together the voids which have been formed in this manner are brought together and may be filled as illustrated in Figure 14 with stones which overlap the two members and conceal the joint. The said overlapping stones may be conveniently secured in place with a small amount of concrete.

As has been illustrated in Figures 11, 12 and 13 inserts of brick 13 may be formed in the sections if desired in order to provide a decorative arrangement.

Referrir J* to Figures 15 to 19 inclusive, it will be observed that the method as applied to the formation of a member having a brick face is similar to that employedto form a member having a stone face. In case of the brick, however, it has been found. desirable to provide a bottom for the framework since greater regularity of surface is required in the case of brick than in the case of stone. The framework 21 is, therefore, provided with a bottom 22, and for convenience in removing the member from the framework, each side member of the frame is removably connected to the adjacent 'side members as by means of the pins 23.

In order that the bricks may be laid evenly and spaced in the proper relationship, the spacers 24 may be provided which may be secured to the bottom of the frame in any desired manner. In forming the member, the bricks are laid into the frame between the spacers 24 and after being laid suitable reenforcing bars may be introduced, and concrete may then be poured into the frame as previously described. For certain purposes it is desirable before pouring the concrete to fill the interstices between the bricks with grout (a mixture of sand, cement and wat-er without any stone or gravel) up to within one inch or a half inch of the tp of the bricks so as to prevent the small stones which are usually present in the concrete mixture from slipping down between the bricks and resting on the spacing material, thus spoiling the external appearance of the joint between the bricks. After the grout has been poured, concrete may be oured into the frame as previously descri ed. If desired, in order to produce color effects, the grout may be colored by the use of the usual materials. As will be observed, the concrete or the grout penetrates the interstices between the bricks as far as the spacers, thus serving to bond the bricks securely together, but the spacers serve the function of the sand used in connection with the stone, in that they protect the front faces of the bricks from the concrete. If desired, eyes and nailin blocks may be embedded in the concrete in t e same manner as in the case of the stone faced member.

In order to break the line between adjacent members the method used in the case of the stone is followed in general. As illustrated in Figures 18 and 34, at the edges of the abutting members alternative bricks are omitted and the voids are filled with sand as illustrated at 25, so that when the vmembers are removed from the frame and set in place as illustrated in Figure 19 the sand drops out, and spaces are provided which may be filled with bricks which may be set in place by hand after the abutting sections are set in place.

Referring to Figures 2l to 25, a method of forming a corner has been illustrated in which the bricks arc laid in the manner previously described. At the end of the framework where it is desired to form a corner, a row of vertical bricks 26 is laid resting on the bottom of the box and a second row of vertical bricks 27 is laid resting on the horizontal row beneath. In order to prevent the concrete or grout from filling the voids between the bricks forming the row 27, a framework 28 is provided having blocks 29 which fill the voids between the bricks and prevent the concrete or grout from running in. This framework may be removed after the concrete is set but before it has hardened. As illustrated in Figure 25,the completed member presents edges having alternate voids which may be filled with bricks in the manner previously described when the next adjacent member is set in place.

Referring to Figures 26 to 33 inclusive, an alternative method of formin a corner is disclosed in which an L-shape frame 3l is used having sides which may be pivoted if desired for easy removal. According to this method, the spacer elements 32 instead of being arranged on the bottom of the box are arranged on the side walls thereof, and in order to support the rear edges of the bricks additional spacer elements 33 are provided which are preferably V-shaped so as to provide two points of support. After the wall is laid to the desired height, reenforcing barsv vlifted into place in the wall and secured there in any desired manner. It will be .understood that. while the frames disclosed herein for purposes of illustration are rectangular in shape, the method may also be employed to form wall sections of any desired shape such as may be designed by an architect for use in any particular part of a building. For example, by providing frames of the desired shape,'arches, lintels, and the like, may be formed of any desired size and shape as specified by an architect.

It will be understood that the invention may be variously modified and embodied within the scope of the subjoined claims.

I claim as my invention:

1. Themethod of forming a wall which comprises precasting a concrete section of sufficient size to form a substantial part of a finished wall, embedding in the front face of said wall during the precasting operation units of facing material such as stone, bricks or blocks which are commonly used in buildings walls, forming voids in said facing material along abutting edges of said sections, hoisting said sections into position, and filling in said voids by embedding units of similar facing material therein, arranged to overlap the joint between the sections.

2. The method of constructing a brickfaced wall of large pre-formed sections which comprises arranging face down in a positioning and protecting form a layer of bricks in mutually spaced relation, arranging along an edge of said layer means for producing voids for the embedding of bridg` ing bricks, applying cement-mix over said layer to penetrate between the bricks to bind the same together and to form a backing slab behind the same of a substantial thickness, allowing the cement-mix to set to form a unitary brick-faced concrete wall unit, removin said unit and assembling it adjacent otEer units with voids juxtaposed to the voids of said unit, and embedding bridging bricks in said ljuxtaposed voids to bridge the line of assembly of said units to produce a continuous brick-face on saidwall.

3. The method of constructing a masonryfaced wall of large pre-formed sections each colnprising a multiplicity of normal sized masonry building elements, which comprises arranging face-down in a positioning and protecting form a layer of such elements in mutually spaced relation, arranging along an edge of said layer means for producing voids for the embedding offbridging elements, applying cement-mix over said layer to penetrate between the masonry elements to bind the same together and to form a backing slab behind the same of a substantial thickness, allowing the cement-mix to set to form a unitary masonry-faced concrete wall unit, removing said unit and assembling it adjacent other units with voids Vjuxtaposed to the voids of said unit, and embedding masonry bridging elements in said juxta osed voids to bridge the line of assemblyl o said units to produce a continuous masonry-face 0n said wall.

In testimony whereof, I have signed my name to this specification this 10th day of October, 1927.
