Description

Cold-formed thin-wall light steel structure floor slab

Technical Field

The utility model relates to a steel construction floor field, especially a light shaped steel structure floor of cold-formed thin wall.

Background

In the traditional floor slab building, a wood plate is mostly adopted as a pouring template of the floor slab, and some simple structural treatment is carried out at the joint of the floor slab and a steel beam; however, the light steel structure composite floor slabs are used in the currently popular light steel structure houses, and the light steel structure floor slabs in the prior art do not have the functions of buffering, damping and silencing, so that improvement is needed.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem that exists, the utility model discloses a light shaped steel structure floor of cold-formed thin wall, its characterized in that: the light steel truss structure comprises a base plate, a buffer layer and a bottom plate, wherein the buffer layer comprises a light steel truss, the light steel truss is formed by connecting an upper chord member, a lower chord member and web members, and the web members are fixedly arranged between the upper chord member and the lower chord member; the lower chord is provided with through holes, the lower surface of the upper chord is fixed with a T-shaped rod, the lower end of the T-shaped rod penetrates through the through holes to extend to the outside of the lower chord and is connected with a buffer spring, one end, far away from the lower chord, of the buffer spring is fixed with the bottom plate, and the upper surface of the bottom plate is provided with a bulge.

Further, the upper chord and the base plate are fixed by screws.

Furthermore, be equipped with the perforation on the arch, it has the perforation reinforcing bar to wear in the perforation, and has placed the broken line reinforcing bar on the perforation reinforcing bar.

Furthermore, the broken line steel bars are of a wavy linear structure formed by bending high-strength steel bars.

Further, the protrusions are spherical or cylindrical.

Further, the length of the part of the T-shaped rod, which exceeds the lower chord, is smaller than the distance between the top of the protrusion and the lower chord.

The utility model has the advantages that: by arranging the buffer layer, when external force is transmitted to the light steel truss and transmitted to the spring, kinetic energy is converted into elastic potential energy, and then the dispersed force is transmitted to the bottom plate, so that on one hand, damage to the floor slab due to force concentration is reduced, on the other hand, the shock absorption effect is achieved, and the sound insulation performance of the floor slab in house application is improved; the broken line reinforcing steel bar of the wavy linear structure formed by bending the high-strength reinforcing steel bar can strengthen the strength of the floor slab structure.
