FRP (Fiber Reinforced Plastic) reinforced PVC (Polyvinyl Chloride) plate-concrete composite floor

Abstract

The invention relates to the technical field of building structures, in particular to an FRP reinforced PVC plate-concrete composite floor which comprises an FRP reinforced PVC formwork system, stress bars and distribution bars inserted into a formwork in a penetrating mode and concrete poured in the PVC formwork system, the FRP reinforced PVC formwork system comprises a PVC formwork body, FRP cloth and FRP partition plates, and the FRP partition plates comprise FRP transverse partition plates and FRP longitudinal partition plates. The FRP longitudinal partition plates are connected with the bottom plate of the PVC formwork body through insertion connection of the T-shaped ribs and the closed grooves, the FRP longitudinal partition plates are connected with the FRP transverse partition plates through insertion connection of the T-shaped blocks and the T-shaped grooves, and the distribution steel bars and the longitudinal load-bearing steel bars penetrate through the holes to be installed. And the bolts are rotated to enable the metal semicircular rings to fix the distributed steel bars and the longitudinal load-bearing steel bars, so that the FRP cloth is adhered to the bottom plate of the PVC template main body, the defect of low bearing capacity of the PVC template is overcome, the integrity of the structure is enhanced, the bearing capacity of the structure is improved, and the service life of the structure is prolonged.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to an FRP reinforced PVC board-concrete composite floor. Background technique [0002] Among the existing prefabricated floors, the commonly used floor forms mainly include reinforced concrete floors, profiled steel plate-concrete composite floors, and laminated floors. As the most widely used floor form in my country, reinforced concrete floor slabs have the advantages of good integrity, high structural rigidity, and good seismic and impact resistance performance. and other disadvantages. The profiled steel plate-concrete composite floor slab makes full use of the material characteristics of steel tensile resistance and concrete pressure resistance, and has the advantages of light weight, high rigidity, good seismic performance, simple construction and short construction period, and high economic benefits. A large amount of steel is used for floor slabs, and the steel ...

Problems solved by technology

The laminated floor slab combines the advantages of the prefabricated floor slab and the cast-in-place floor slab. It is not only easy to assemble, convenient to construct, and has good integrity, but also has further improved seismic performance. However, this type of floor slab has many construction procedures and complex node structures.
