Advantage:It is point that the double-fold intensity that one layer of flanging is an integral structure above-mentioned at least, which is more than two-layer folded edge, The double-fold intensity of body formula structure.
The internal layer flanging of the G types beam is curved by the two side walls in the upper side wall of G type beams, lower wall or rear wall The spliced flanging folded, outer layer flanging are the integral type flangings bent out by the front side wall of G type beams.
Advantage:It is bent by two side walls using internal layer flanging, this bending mode can facilitate outside G type beams The bending of layer flanging, outer layer flanging is the integral type flanging bent out by the front side wall of G type beams, can make the two-fold of G type beams Side is more regular.
The double-fold of the G types beam is equipped with fastener receptacles and location hole, be equipped with outside the outer ones of G type beams with The convex of stud location cooperation.
Advantage:Convex and location hole realize positioning during the connection process, can facilitate fastener connection installation.
The G types beam material is aluminum clad zinc plate.
Advantage:Aluminum clad zinc plate is not perishable, reduces electroplating work procedure.
To achieve the above object, the technical solution of the utility model G types beam is:The end of G type beams is upper by G type beams At least one of side wall, lower wall, rear wall and front side wall side wall bends out internal layer flanging, passes through the upper side wall, downside It is different from wall, rear wall and front side wall and bends out the outer layer that at least one bending increase of internal layer flanging is bonded with internal layer flanging Flanging makes G type beam ends form double-fold.
The double-fold of the G types beam, at least one layer of flanging are an integral structure.
The internal layer flanging of the G types beam is curved by the two side walls in the upper side wall of G type beams, lower wall or rear wall The spliced flanging folded, outer layer flanging are the integral type flangings bent out by the front side wall of G type beams.
The double-fold of the G types beam is equipped with fastener receptacles and location hole, is equipped with and uses outside the outer one of G type beams In the convex with connected piece location fit.
The G types beam material is aluminum clad zinc plate.
The invention content of the G type beams is identical as the G type girder constructions in the invention content of above-mentioned the utility model switchgear, Advantageous effect is not repeated to illustrate.
