Reinforced concrete overlapped floor slab

Abstract

The invention discloses a reinforced concrete overlapped floor slab, which comprises a prefabricated ribbed construction member plate (12), a lateral reinforcing steel bar (9) and a concrete overlapped layer (10), wherein the prefabricated ribbed construction member plate (12) comprises a bottom plate (1) and a longitudinal rib (2); the longitudinal rib (2) is provided with a lateral through hole (8); the bottom of the bottom plate (1) is provided with a hole or groove (3); a nut (7) is embedded in the hole or groove (3); the nut (7) is connected with a first bolt (4) on a platen (11); and a connecting rod, namely a full-length connecting rod (5) or a short rod (13), is fixedly connected between the platen (11) and the bottom plate (1). During construction, the prefabricated ribbed construction member plate (12) is firstly erected; the bottom of the prefabricated ribbed construction member plate (12) is connected with the platen (11) and is provided with the connecting rod; the lateral reinforcing steel bar (9) is paved at the upper part of the prefabricated ribbed construction member plate (12); the concrete overlapped layer (10) is poured; and the connecting rod is removed after the strength of the concrete overlapped layer (10) reaches the standard. The bottom of the prefabricated ribbed construction member plate is provided with the connecting rod, thereby solving the problem of slab staggering in the construction process, and guaranteeing a flat and beautiful floor slab bottom.

Description

Technical field: [0001] The invention relates to the field of building construction, in particular to a reinforced concrete laminated floor slab. Background technique: [0002] At present, some high-rise buildings use laminated floor slabs, which are convenient for construction, do not require on-site formwork, and are relatively low in cost, and are convenient for hoisting and transportation. However, due to the joints between the prefabricated ribbed member slabs, the prefabricated ribbed member slabs are prone to misalignment at the joints, so that after pouring the laminated concrete, the bottom of the floor slab is uneven, which affects the appearance. The thickening of the plastering layer will increase the construction cost. The patent (201020142733.6) once mentioned a method to solve this problem, but it also has the following disadvantages: 1. The anti-deformation rigidity provided by the steel plate is limited, and the floor slab may also have certain unevenness. ...

However, due to the joints between the prefabricated ribbed member slabs, the prefabricated ribbed member slabs are prone to misalignment at the joints, so that after pouring the laminated concrete, the bottom of the floor slab is uneven, which affects the appearance. The thickening of the plaster layer will increase the construction cost

The patent (201020142733.6) once mentioned a method to solve this problem, but it also has the following disadvantages: 1. The anti-deformation rigidity provided by the steel plate is limited, and the floor may have certain unevenness

2. Waste of steel, the steel plate is buried in the post-cast concrete and cannot be reused
