Assembly type composite floor slab

Abstract

The invention provides an assembly type composite floor slab. The rigidity of a composite slab and the shear capacity of the combination surface can be improved, the production mode can be optimized, and construction can be convenient. The assembly type composite floor slab comprises a composite slab prefabrication bottom slab, a concrete composite layer and a plurality of trusses. Longitudinal pre-stress steel bars and transverse pre-stress steel bars are arranged in the composite slab prefabrication bottom slab, fold line steel bars are arranged on the joints of the composite slab, the concrete composite layer is poured on the composite slab prefabrication bottom slab, the bottoms of the trusses are embedded in the composite slab prefabrication bottom slab, and the tops of the trusses are higher than the upper surface of the composite slab prefabrication bottom slab and buried in the concrete composite layer.

Description

technical field [0001] The invention relates to a prefabricated floor slab, in particular to a prefabricated laminated floor slab, which is widely used in the field of construction and is suitable for use in prefabricated integral buildings. Background technique [0002] The industrialization of construction has become an inevitable trend in the development of my country's construction industry. It has become the mission of modern construction practitioners to transform the cast-in-place construction model into a prefabricated, on-site assembly-type building model. [0003] At present, the laminated floor mainly includes ordinary flat-plate prestressed concrete laminated floor, prefabricated ribbed prestressed concrete laminated slab and ordinary reinforced truss laminated slab. Ordinary flat-plate prestressed concrete composite panels rely on the rough surface of the upper surface of the base plate to combine with the superimposed layer concrete, which resists section shear...

AI Technical Summary

Problems solved by technology

Ordinary flat prestressed concrete composite slabs rely on the rough surface on the upper surface of the base plate to combine with the concrete of the laminated layer, which resists section shear force and has poor shear resistance; prefabricated ribbed prestressed concrete composite slabs have concrete ribs, which are useful The ribs are easy to be damaged during the hoisting and transportation process, and it is not easy to pass through the steel bars; because of the ordinary steel bar truss laminated slabs, the plate stiffness is small and the required slab thickness is large because of the use of ordinary reinforced steel bars, which increases the weight of the structure, and The plate bears a small load range
