Problems solved by technology

[0002] The commonly used reinforced concrete hollow prefabricated component slabs are long strips with a through hole in the middle. This kind of hollow prefabricated component slab 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. 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. The protruding block, the protruding block closely acts as a formwork, and the concrete can be poured directly in the groove-shaped cavity, and the splicing part does not need to be suspended; this design improvement solves the problem of easy cracking, poor crack resistance, Poor integrity and other issues
However, the actual production, hoisting, and transportation of this configuration have brought great inconvenience, and the damage rate of the corner bumps is high, and the production cost cannot be effectively controlled, so it has not been popularized. The splicing problem is still the main technical difficulty

Example Embodiment

[0035] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0036] See figure 1 The structure diagram of a pre-stressed concrete hollow floor in the embodiment of the present invention is shown, which includes a slab body 1, a transverse reinforcement 2, and a longitudinal reinforcement 3. The plate body 1 is provided with at least one through hole 4, and double-sided ribs are used. The transverse ribs 2 and longitudinal ribs 3 are embedded in the plate body 1. The top surface of the plate body 1 is provided with staggered transverse ribs 2, longitudinal ribs 3, and plate body 1. The longitudinal ribs 3 are evenly arranged on the bottom surface. Both sides of the top surface of the board body 1 are also provided with transverse rib grooves 6, the transverse rib grooves 6 on both sides are arranged in pairs, and both ends of the transverse rib 2 extend into a pair of transverse rib grooves 6 but do not exten

Abstract

The invention discloses a prestressed concrete hollow floor slab and a construction method thereof, and relates to the technical field of prefabricate floor slabs. The prestressed concrete hollow floor slab comprises a slab body, transverse ribs and longitudinal ribs; the transverse ribs are arranged on the top surface of the slab body; the longitudinal ribs are arranged on the top surface and thebottom surface of the slab body; side wall grooves are formed in the side wall of the slab body; and transverse rib grooves are formed in the two sides of the top surface of the slab body. Accordingto the prestressed concrete hollow floor slab of the invention, the floor splicing part of the prestressed concrete hollow floor slab is not prone to crack, the crack resistance is high and the integrity is good, the probability of damage and corner breaking is low, and actual production, hoisting and transportation are very conveniently. In addition, superposition production can be realized, thedemand of production sites is significantly reduced, a large amount of land cost is reduced, the production cycle is fast, a traditional floor slab production process can be followed, and the construction method is mature and reliable.
