Abstract

The utility model discloses a steel bar truss floor bearing plate, which comprises a bottom plate and a steel bar truss arranged on the bottom plate, wherein the steel bar truss comprises a web member steel bar arranged on the bottom plate, an upper chord steel bar arranged on the web member steel bar and a lower chord steel bar arranged on the web member steel bar; and can be tightly connected with the bottom plate through the bending part.

Description

Steel bar truss floor support plate

Technical Field

The utility model belongs to the technical field of building construction, and particularly relates to a steel bar truss floor bearing plate.

Background

The steel bar truss floor support plate is more and more popular in the market due to the advantages of standardization, factory production, stable quality, uniform steel bar distribution, accurate size and the like.

In the prior art, a steel bar truss floor support plate generally comprises an upper chord steel bar, and two lower chord steel bars form a steel bar truss.

However, in the prior art, the steel bar truss is composed of one upper chord steel bar and two lower chord steel bars, so that the steel consumption is too large, the cost is too high, and the purposes of material saving, cost reduction and efficiency improvement cannot be achieved.

Among the prior art, steel bar truss floor carrier plate generally includes the bottom plate of galvanized sheet material or wooden material and connects the steel bar truss in bottom plate one side. The steel bar truss is assembled and fixed on the bottom plate through a connecting fastener.

However, the bottom surface of the existing connecting fastener can not be tightly attached to the upper surface of the bottom plate frequently, and after a concrete floor slab is poured, the hollowing phenomenon can be caused, so that the concrete at the bottom of the connecting fastener is broken, and the quality of the steel bar truss floor bearing plate is seriously influenced. When the concrete floor is poured by adopting the steel bar truss floor support plate, after the concrete floor is poured, the bottom plate is required to be detached because the bonding strength between the bottom plate made of the galvanized plate or the wood and the mortar cannot meet the design requirement, so that the concrete floor meets the design and use requirements. And a large amount of manpower and material resources are needed for dismantling the bottom plate, the construction time is prolonged, and the construction cost is increased.

SUMMERY OF THE UTILITY MODEL

The utility model provides a steel bar truss floor bearing plate for overcoming the defects of the prior art.

In order to achieve the purpose, the utility model adopts the following technical scheme: a steel bar truss floor bearing plate comprises a bottom plate and a steel bar truss arranged on the bottom plate, wherein the steel bar truss comprises web member steel bars arranged on the bottom plate, upper chord steel bars arranged on the web member steel bars and lower chord steel bars arranged on the web member steel bars, the web member steel bars are provided with bending parts, the bending parts are connected with the bottom plate, the bending parts are arranged perpendicular to the upper chord steel bars and extend along the horizontal direction, the steel bar truss is composed of only one upper chord steel bar and one lower chord steel bar, the steel consumption is greatly reduced, and the cost is reduced; and can be tightly connected with the bottom plate through the bending part.

Preferably, the bottom plate is made of concrete or cement mortar, and the bent part is buried in the bottom plate.

Preferably, the material steel sheet die block of bottom plate, the kink is fixed with bottom plate upper surface laminating.

Preferably, the bottom plate is made of concrete or cement mortar, and the thickness of the bottom plate is 8-30 mm.

Preferably, the bottom plate is made of a steel plate bottom die and has a thickness of 0.4-5 mm.

Preferably, the web member reinforcing bars are uniformly arranged along the direction of the upper chord reinforcing bar.

Preferably, the web member reinforcing steel bars are symmetrically arranged or staggered symmetrically at intervals relative to the upper chord reinforcing steel bars.

In conclusion, the steel bar truss only needs one upper chord steel bar and one lower chord steel bar, so that the steel consumption is greatly reduced, and the cost is reduced; and can be tightly connected with the bottom plate through the bending part.
