INTERSECTING JOINT CONSTRUCTION v v I Filed May 4, 1956 2 Shqetg-Sh'eet 2 "INVENTQR figyak Maurice Moore ATTORNEYS United States Patent 2,904,144 I INTERSECTING JOINT CONSTRUCTION This invention relates to joint construction, and particularly to the construction of intersecting joints between adjacent edges of panels or the like comprising the walls of containers, buildings, roofs, or similar structures.
This application is a continuation-in-part of my copending application Serial No. 209,169, filed February 2, 1951 (now Patent No. 2,751,109), which, in turn, disclosed improvements on the subject matter of my application Serial No. 167,793, filed June 13 1950 (now Patent No. 2,673,659, dated March 30, 1954) and my copending application Serial No. 177,106, filed August 1, 1950, now Patent No. 2,761,582, dated Sept. 4, 1956.
Many proposals have been made heretofore for constructing containers, buildings and similar structures of separable panel-like sections to render the structures readily assemblable and demountable. Many diiferent proposals for construction of the joints between adjacent panels have been proposed but, prior to my invention, no practical or simple solution was found to the problem of effecting a tight and continuous joint in the region wherein two such joints intersect.
According to the present invention, the joint between adjacent panels is formed by employing clamping bars on opposite faces of the structure wall, which bars each engage and overlie adjacent edge portions of the panels being joined. The invention includes interlocking means between the panels and bars to prevent lateral withdrawal of the panel edges from between the clamping and sealing bars. While the interlocking construction may take many forms, it preferably comprises features in the nature of transverse flanges extending along the edges of each panel and complementary grooves in the clamping bars. In regions where one such joint extends transverse to and intersects a similar joint, the clamping bars are constructed in a unique and novel manner whereby to provide a continuation of their channels around the corner from one joint to the joint it intersects whereby the flanges on the corresponding panels may extend continuously around a panel corner and thus insure continuous closing and/or sealing of the joint around the intersection. The novelty resides in part in the provision of a lateral notch in at least one of the clamping bars at the intersection and a complementarily formed end on the corresponding clamping bar of the intersecting joint, whereby the joint at the intersection not only constitutes a continuous closure but the interengagement between the bars locks one joint against shifting movement relative to the joint it intersects.
It is therefore a principal object of this invention to provide an interlocking joint between panel edges formed to interengage with a similar joint which it intersects and to provide continuous interlock between the parts and effective closure and/or sealing throughout the intersec.
tion without bulky or complicated additional parts. 1
Another object of the invention is to provide novel structure as set forth wherein the parts are easily assembled and disassembled.
Still another object of this invention is to provide an.
Patented Sept. 15, 1959 intersecting joint construction as set forth wherein the intersecting joints are interlocked to prevent relative shifting of the parts.
A further object of this invention is to provide joint intersection construction as described including a flowable sealing material in the joint and a novel relationship between the sealing material and the structural elements at a joint intersection.
Further and additional objects and advantages will become apparent to those skilled in the art as the description proceeds in connection with the accompanying drawings, wherein:

Figs. 9 and 10, respectively, illustrate further modifications of joint intersection construction embodying the principles of the present invention.
The structure shown in Fig. 1, for purpose of illustration only, may be considered to be a tank or container of generally cylindrical form having end walls 2 and side wall panels 4. Adjacent edges of adjacent panels 4 are securely held together by a joint structure generally identified by numeral 5. The ends of the panels 4 are joined to the end panels 2 by a joint construction generally indicated by numeral 6. It is contemplated that the joints 5 and 6 be of substantially identical construction.
As is inevitable to properly form a complete structure, the joints 5 must intersect the joints 6 at a plurality of positions on the structure. This invention is directed principally to the relationship of the parts at those joint intersections generally identified by characters A and B of Fig. 1, by way of illustration.
Referring now to Fig. 2, which is an enlarged transverse sectional view through the joint 5 and may be considered as representative of a section through the joint 6 also, adjacent panels 4 are formed at their edges with inwardly extending continuous peripheral portions 8 terminating in outwardly directed transverse flanges 10. An upper clamping and sealing bar 12 is provided with a longitudinal channel 14. The side edge portions 15 of the bar 12 are so configured as to nest snugly within the space between the flanges 10 and portions 8 of the panels and is shown with its outer surface lying substantially flush with the outer surface of the panels although such flush relationship is not essential. This is merely an illustrative example since the features of the invention do not require 'that the clamping bar 12 be flush with the outer surface of the panels.
The channels 14 are provided with undercut portions 16 serving to retain therein a self-sustaining but flowable strip of deformable sealing material 18. The material 18 may be rubber or the like.
A clamping bar 20 extends along the joint 5 on the opposite face thereof from the bar 12 and is configured on one side to define channels 21 snugly embracing adjacent portions of the panels 4 and particularly to snugly engage the flanges 10 and portions 8 of each panel with a longitudinal rib portion 22 extending inwardly between the spaced flanges 10 and into engagement with the sealing material 18. Suitable means, such as screws 24, are provided to draw the bars 12 and 20 together to thereby clampingly lock the edge portions of the panel 4 in the joint and apply pressure to material 18. The screws 24 pass frictionally through the material 18 and are retained thereby against loss even when the various parts are disassembled.
As will be obvious, clamping of the bars 12 and 20 together causes rib 22' to apply pressure to the sealing material 18 and causes the same to flow to completely fill and sealingly engage all portions of those members bounding and defining the peripherally closed passage way, in channel 14, along the joint.
Referring now to Fig. 3, the joints and 6 identified therein are both constructed as described in connection with Fig. 2 but whereas, in the illustrated embodiment, joint 5 is rectilinear, joint 6 is circular since it extends around the periphery of the structure, and the outer clamping bar 12' of joint 6 is curved as clearly indicated in the perspective showing of Fig. 4.
The clamping bar 12' is provided with a notch 26 extending inwardly from one edge thereof substantially to the longitudinal center line of the bar and positioned in alignment with the joint 5. The clalmping bar 12 of joint 5 is formed with an end portion 27 complementary to the notch 26 and snugly fitting therein. The notch 26, as clearly shown in Fig. 4, is formed in only the body of the bar 12', the strip of sealing material 18 therein is notnotched. Thus, a portion of the top surface of the strip 18 and the edge portion thereof are exposed in the notch 26, as clearly shown in Fig. 4. The scaling material 18 in the joint 5 terminates, at the intersection, in a transverse surface 28 (Fig. 3) so positioned that it abuts the exposed edge surface of the sealing material in joint 6 when the portions are in the relationship shown in Fig. 3. Thus it will be seen that the intersections or interen gaging faces between sealing strips 18 at the intersection do not coincide with the abutting surfaces between the sealing bars 12 and 12' but are in oflset or staggered relation thereto. As the sealing material 18 is put under pressure by virtue of clamping the joint bars together, some longitudinal flow thereof will take place to firmly press the faces of those strips together in tight sealing relation at the joint intersection and thus form a continuous seal at the intersection. Although not shown in Fig. 3, the clamping bar 20 of the joint 5 and a corresponding bar of the joint 6 are similarly notched and formed to engage in the same manner as described in connection with the bars 12 and 12-. The invention does encompass, however, an arrangement wherein the strip of sealing material is formed or bent to extend integrally around the corner of certain joint intersections. Later description in connection with a modified form (as shown in Figs. 7 and 8) will apply equally well to the clamping bars of the form just described and it is to be understood that the flanges of the panels 4 extend continuously around the corners thereof at the joint intersection. As will be obvious from the later description, the channel 14 and the surfaces of the clamping bar will be so related at the intersection as to form continuous panel and flange-engaging portions extending along one joint and continuously around the corner along the intersecting joint.
As will be clear, the form of joint intersection just described defines a simple and readily assembled arrangement without the necessity of providing additional or bulky elements and serves not only to form a tight and continuous joint at the intersection but also serves to prevent shifting movement of the panels 4 longitudinally of the joint 6, by virtue of the interlock between bars 12 and 12'. The described construction also provides uninterrupted boundary surfaces at the periphery of the abutting faces of material 18 at the intersection.
Figs. 3 and 4 illustrate the joint intersection shown generally at A in Fig. 1. The joint shown at B of Fig. l is essentially identical to that shown at A, except that the corresponding notch 30 is not formed as a single notch intermediate the ends of the bar 12 but is defined by beveled end portions of the bar 12 which end portions abut each other at 32 directly aligned with the centerline of the joint 5. Clearly, the present invention encompasses both forms as shown at A and B.
The embodiment illustrated specifically in Figs. 5 through 8 is similar in all essential respects to that of Figs. 2 through 4 but-omits the sealing material 18 of Fig. 2. Referring specifically to Fig. 5, which illustrates a sectional view of a joint that could be employed for the structure of Fig. 1 and corresponds generally to the showing of Fig. 2, the panels 4 are provided with downwardly and inwardly inclined edge portions 40 terminating in outwardly directed flanges 42. The clamping bar 44 is provided with a longitudinal rectangular channel 46 and its edge portions 45 are configured and arranged to snugly nest Within the space between flanges 42 and edge portions 40. An inner clamping bar 48 is provided with an inner face configured to define channels 49 snugly embracing the inner surfaces of the portions 40 and flanges 42 and is provided with a longitudinal rib 50 extending outwardly between the flanges 42 and holding those flanges in spaced relation and in engagement with the inner side faces of the channel 46. Clamping screws 24 are employed to clamp the bars 44 and 48 together and to clamp the edge portions of the panels 4 therebetween.
The structure of Fig. 5 is obviously adapted to the intersecting joint construction described in connection with Figs. 1 through 4 and such a joint is shown in plan in Fig. 6 wherein the clamping bar 44' of one joint is provided with a notch 52 in one of its edges extending substantially to the longitudinal center line of that bar. The other clamping bar 44 has its end 54 formed complementary to the notch 52 and nested therein.
As will be obvious from Figs. 7 and 8, the flanges 42 extend continuously along the adjacent edges between panels 4 and around the corner to extend along the edges adjacent the third panel 4' (the same being true of the flanges 10 of Fig. 2). As is evident from the lower portion of Fig. 7 and from Fig. 8, the notched connection between the bar 48 and bar 48 on one hand and bar 44 and bar 44' on the other hand is such that the rib 50 on the bars 48 and 48' and the channels or grooves 49 alongside that rib extend continuously around the corner of the joint intersection to receive the continuous corre sponding portions of the edges of panels 4. In like manner the mitered relation of the bars 44 or 44' is such that the channels 46 thereof intersect to form a T-shaped channel at the intersection to receive the continuous flanges 42. It will be obvious that when the fitted bars of Fig. 8 are inverted and applied to the top of the assembly of Fig. 7 in the obvious manner, the entire structure at the joint intersection will be securely locked together against any relative shifting and the arrangement provides for a continuous mechanical closure and mechanical seal throughout the joints and their intersection even though no hermetic sealing means are provided.
While Figs. 6 through 8 illustrate a T-shaped joint wherein one of the bars is notched, corresponding to the joint at A of Fig. 1, it will be obvious that the bar 44 of Fig. 6 may, in fact, constitute two bars having their ends in abutment at the apex of the notch 52, in the manner shown at B in Fig. 1.
Fig. 9 illustrates a further adaptation of the present invention wherein four panels 4 meet at a joint intersection C. In this embodiment the bars 44 and 48 are each formed with pointed mitered ends 54. Thus, two aligned bars 44, in eifect, define a bar having notches on opposite edges to receive the end portions of transverse bars 44. The arrangement is clearly shown in Fig. 9 and it is believed obvious that such an arrangement incorporates the basic features of the described invention.
Fig. 10 shows a further adaptation of the invention to a cross-over joint intersection wherein the bars 44 terminate short of the joint intersection between four adjacent panels 4 and wherein a cross-shaped fitting 56 is provided at the joint intersection. Each leg of the fitting 56 is formed to a cross-section identical to that of the bars 44 and its central portion is configured like the adjacent portions of the bars 44 of Fig. 9 to define an integral cross-over member. Obviously, the fitting 56 provided for engagement of and closure with the continuous flanges 42 shown in Pig. 7. If desired, a fitting 56 may be provided on one face of the structure while the bars 48 on the other-face thereof may be mutually mitered as suggested in Fig. 9, or a fitting corresponding to that shown at 56 may be provided for the intersection between bars 48 on the other side of the structure.
Clearly, such arrangements as shown in Figs. 9 and 10, in connection with the form of joint of Fig. 5, may also be employed with the sealed joint shown in Figs. 2 through 4.
