Conventionally, a pair of crosspieces and a small crosspiece have been connected using fixing tools such as rivets and screws when each crosspiece is made of an aluminum alloy profile. Moreover, if each crosspiece was made of iron, they were connected by welding or the like.

[Problems to be Solved by the Invention] Therefore, in the past, a lot of effort was required for assembly, and when a fixing tool was used, the number of parts further increased, resulting in high costs.

The purpose of the present invention is to be able to connect opposing crosspieces and a small crosspiece disposed between them without the need for fixing tools or welding, and to be easy to assemble.
The object of the present invention is to obtain an architectural lattice body whose strength can be greatly improved.

[Means for Solving the Problems] In order to achieve the above object, the architectural lattice body of the present invention includes a plurality of hollow small pieces arranged between a pair of metal crosspieces facing each other. The crosspiece has grooves extending in the longitudinal direction on at least one side wall thereof, and grooves are formed at the bottoms of the grooves at both ends of the small crosspiece and on the other side wall opposite to the one side wall, and grooves are formed at both ends of the small crosspiece. A receiving portion consisting of a hole is formed on the other side wall of the section on an extension line of the groove provided therein, and a protrusion extending in the longitudinal direction is integrally formed on the opposing surfaces of the pair of opposing metal bars. A single groove having a width equal to the width between the inner bottom surface of the groove of the small crosspiece and the outer surface of the other side wall is provided at the mounting position of each of the small crosspieces. A portion of the protrusion that fits into the groove of the small crosspiece is formed, and the thickness of the groove is approximately equal to the width of the groove of the small crosspiece and the width of the groove. The groove and the protrusion are fitted into each other, and a portion of the edge of the protrusion located near the single groove is plastically deformed to fit into the receiving portion.

Since the grooves provided on both side walls of the section are inserted into each other, the single groove is fitted into the end of the small crosspiece, and the grooves of the small crosspiece are fitted into parts of the protrusions, respectively. , and the groove is fitted over the entire protruding width of the protrusion. In this fitting, by providing the single groove in the protrusion, positioning during fitting is easy, and there is little resistance at the initial stage of fitting, so fitting can be done easily. By these fittings, it is possible to prevent each crosspiece from moving relative to each other in the thickness direction, and by fitting the single groove and the groove of the small crosspiece, it is possible to prevent each crosspiece from moving in the longitudinal direction of the protrusion. Next, in the vicinity of the single groove of the protrusion, the edge of the protrusion is pressurized to plastically deform it toward the small crosspiece, and this plastically deformed portion is inserted into the receiving portion of the small crosspiece. This prevents the small crosspiece and the metal crosspiece from moving freely in the longitudinal direction of the small crosspiece and separating the small crosspiece and the metal crosspiece.

That is, as described above, the metal crosspiece and the hollow small crosspiece can be connected without using welding stops or fasteners.

Then, as described above, the single groove is fitted to the end of the small crosspiece so as to sandwich both side walls of the small crosspiece, and the groove of the small crosspiece is fitted to a part of the protrusion. The grooves are fitted over the entire protruding width of the protrusions and sandwich the protrusions in the thickness direction, and
Since the single groove does not interfere with the deformation of the plastically deformed part, it is possible to secure a large amount of deformation in this deformed part and securely fix the small crosspiece.Moreover, the small crosspiece is hollow and its own Since it has high strength, the assembly strength between the metal crosspiece and the small crosspiece can be improved.
