Description

Non-welded prefabricated truss {NON-WELDED PREFABRICATED TRUSS}

The present invention relates to a non-welding prefabricated truss.

In general, the exterior walls of buildings are finished with various types of panels or stone materials.

In order to finish the outer wall of a building with panels or stones, a truss structure is formed by interconnecting horizontal and vertical members in a lattice form on the outer wall, and after fixing the truss structure to the outer wall, the truss structure is insulated and the outer wall is finished with panels or stones. do.

Since the truss structure forming the horizontal and vertical members in a lattice shape serves as a framework for fixing panels or stones, they must be firmly coupled to each other so as not to be easily deformed or separated by external forces.

In general, horizontal members and vertical members constituting a truss structure are welded by workers at a construction site.

If a worker welds the horizontal and vertical members that make up the truss structure and connects them to each other, a fire may occur during the welding process, a worker's body may be damaged during welding, and it takes a lot of time to manufacture the truss structure. This has the problem of significantly lowering productivity.

In order to solve this problem, in recent years, a non-welding technology has been developed in which truss structures are firmly coupled to each other by a screw fastening method without welding.

The upper and lower ends of the second side plate 891 are bent to contact the second guide part 260 to form a pair of bending plates 893 .

In one embodiment of the present invention, the pair of bending plates 893 serve to prevent deformation of the shape of the second side plate 891 by distributing an excessive load applied to the second side plate 891 .

A plurality of second toothed portions 895 may be formed at the ends of the pair of bending plates 893 that come into contact with the second guide portion 260. can

The second toothed portion 895 reduces the contact area with the second guide portion 260 so that the bending plate 893 can be more smoothly inserted into the second prefabricated pipe 200 .

In one embodiment of the present invention, the base portion 850 is coupled to the third plate 130 of the first prefabricated pipe 100 through a coupling member 810, and the first and second reinforcement portions 870 and 890 ) Are inserted into the second prefabricated pipe 200 and contacted with the inner surfaces of the fifth plate 210 and the sixth plate 220, respectively, so that the second prefabricated pipe 200 and the first prefabricated pipe 100 firmly connected

In one embodiment of the present invention, the second guide portion 260 and the first and second reinforcing portions are formed by forming first and second toothed portions 875 and 895 at a portion in contact with the second guide portion 260. The pipe coupling member 800 and the second prefabricated pipe 200 can be quickly connected by reducing frictional resistance as the points 870 and 890 make point or linear contact.

As described in detail above, the non-welding prefabricated truss according to the present invention prevents fire occurrence, prevents workers from falling, and significantly reduces the time required for assembly by firmly coupling the horizontal and vertical members with brackets instead of welding. This has the effect of improving productivity.

In addition, the non-welding prefabricated truss according to the present invention combines the bracket with the vertical member using a fastening member in a state where the bracket is inserted into the end of the horizontal member, compared to the method of fastening the horizontal member and the vertical member with each fastening member. is reduced by half to significantly reduce the time required for assembly, thereby improving productivity.

On the other hand, the embodiments disclosed in the drawings are only presented as specific examples to aid understanding, and are not intended to limit the scope of the present invention. It is obvious to those skilled in the art that other modified examples based on the technical idea of the present invention can be implemented in addition to the embodiments disclosed herein.
