Problems solved by technology

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

Embodiment Construction

[0030] The present invention will be further described below in conjunction with accompanying drawing.

[0031] The invention is attached Figure 1-20 As shown, a reinforced concrete laminated floor slab includes a prefabricated ribbed member slab 12, transverse steel bars 9, and a concrete laminated layer 10. The prefabricated ribbed member slab 12 includes a reinforced concrete bottom slab 1 and a longitudinal rib 2 on which the There are transverse through holes 8 . The present invention is characterized in that there are holes or grooves 3 at the bottom of the reinforced concrete bottom plate 1, and nuts 7 are pre-embedded in the holes or grooves 3, and the nuts 7 are connected with the bolts 4 on the pressure plate 11, and between the pressure plate 11 and the bottom plate 1 Fix the long and long connecting rod 5 or the short rod 13. figure 1 It is a schematic diagram of connecting the rectangular rib prefabricated component plate 12 with the pressing plate 11 and the l...

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. ...
