Problems solved by technology

[0002] The commonly used reinforced concrete hollow prefabricated component slabs are long strips with through holes in the middle. This kind of hollow prefabricated component slabs has the advantages of low cost, convenient construction, and easy production. On the wall or beam, and then hang the formwork at the joint of adjacent prefabricated component slabs and fill the joints with concrete to form a hollow floor slab. Concrete filling, the process is complicated, time-consuming and labor-intensive, the joints are easy to crack, the crack resistance is poor, and the joints are prone to leakage; the connection between adjacent prefabricated component panels is weak, and the integrity of the assembled floor is poor

Embodiment Construction

[0012] refer to figure 1 , Figure 2, Figure 3, Figure 4 , Figure 5 , Image 6 , the reinforced concrete hollow prefabricated member board includes a reinforced concrete board body 2, a through hole 1 is opened in the middle, and lower protruding blocks 4 are arranged on both sides of the reinforced concrete board body 2, and the width of the lower protruding block 4 is L≥ 3.5 cm, which can not only function as a template, but also stagger the upper and lower joints. There are connecting steel bars 3 on both sides of the board body 2. The upper plane 5 of the lower protruding block 4 can be parallel to the bottom plane, or it can form an angle α (α≤45 degrees), so that the lower protruding block 4 has a shape with a thick inside and a thin outside, which not only increases the bending resistance of the lower protruding block 4 force, without affecting the thickness of the cast-in-place concrete 7 at the joint. There are also upper protruding blocks 10 on the tops of both ...

Abstract

The hollow reinforced concrete slab includes reinforced concrete slab body and its two sides have two stretched blocks in the lower part and stretched steel bars. When constructing floor, after the hollow reinforced concrete slabs are set on support, trough will formed between two adjacent slabs, the stretched steel bars are connected and the trough is deposited with concrete to constitute integral floor. The floor has high anti-cracking performance and anti-seepage performance, strengthened connection between adjacent floor slabs and raised floor entirety.

Description

Technical field: [0001] The invention relates to the field of building construction, in particular to a reinforced concrete hollow prefabricated member board. Background technique: [0002] The commonly used reinforced concrete hollow prefabricated panel is long strip with through holes in the middle. This kind of hollow prefabricated panel has the advantages of low cost, convenient construction and easy fabrication. When assembling the floor, first place the hollow prefabricated panel on On the walls or beams, and then the hanging formwork is filled with concrete at the splicing point of the adjacent prefabricated member panels to form a hollow floor slab, but this hollow prefabricated member panel assembles the floor slab, which has the following shortcomings: the hanging form at the splicing point of the adjacent prefabricated member panels is used. Filling the joints with concrete is complicated, time-consuming and labor-intensive. The joints are prone to cracking, the c...
