Limiting device for preventing steel structure truss from deviating

Abstract

The invention relates to the technical field of trusses, and discloses a limiting device for preventing a steel structure truss from deviating. The limiting device comprises a shell, the outer side of the shell is in threaded connection with screws, the inner side of the shell is fixedly connected with pressing blocks, the right side of the shell is movably connected with a steel frame, the right side of the shell is fixedly connected with pressing blocks, grooves are formed in the inner side of the steel frame, zinc cylinders are fixedly connected to the inner walls of the grooves, insulating layers are fixedly connected to the left sides of the zinc cylinders, round holes are formed in the inner walls of the insulating layers, and carbon rods are elastically connected to the outer sides of the insulating layers. According to the limiting device for preventing the steel structure truss from deviating, dry batteries are formed through the carbon rods and the zinc cylinders; and when the truss is impacted, bolts are prevented from loosening, a gap between the truss and a steel structure is prevented from being enlarged, and the truss is prevented from deviating, so that the truss is prevented from losing the supporting capacity, the safety coefficient of use of the truss is improved, and the service life of the truss is prolonged.

Description

technical field [0001] The invention relates to the technical field of trusses, in particular to a limiting device for preventing the deviation of steel structure trusses. Background technique [0002] Truss is a structure composed of rods connected by hinges at both ends. Truss is generally a plane or space structure with triangular units composed of straight rods. Truss is widely used in steel structures. Existing trusses are used for fixing When the truss is usually connected by bolts, the bolts will loosen, which will cause the truss to shift and lose its supporting capacity. [0003] When the existing trusses are fixed, bolts are mostly used. During long-term use, the trusses will be collided, causing the bolts to loosen, causing the gap between the trusses and the steel structure to increase, and causing the trusses to break down. The offset causes the truss to lose its supporting capacity, reduces the safety factor of the truss, and reduces the service life of the tr...
