Prefabricated laminated slab suitable for laying floor heating pipeline and preparation process

Abstract

The invention discloses a prefabricated laminated slab suitable for laying a floor heating pipeline and a preparation process. According to the prefabricated laminated slab, stirrup reinforcing steelbars are adopted to replace pins, the stirrup reinforcing steel bars and reinforcing steel bars in the prefabricated laminated slab are laid, bound and fixed at the same time, and truss bars in the prefabricated laminated slab are canceled, so that the steel bar laying and binding time in the prefabricated laminated slab is effectively shortened, and the production and machining efficiency of theprefabricated laminated slab is remarkably improved compared with a plug pin manner; the truss ribs are cancelled, so that the production cost of the prefabricated laminated slab is reduced; the stirrup reinforcing steel bars are higher in strength, so that the stirrup reinforcing steel bars are prevented from being broken during on-site assembly construction; the stirrup reinforcing steel bars are simple and reasonable in structural design and can be conveniently bound and fixed to the reinforcing steel bars in the prefabricated laminated slab, and the vertical precision of the upper end of an n-shaped rod is guaranteed; the prefabricated laminated slab is simple and reasonable in structural design, high in preparation implementation feasibility and high in economic practicability, and has potential application and popularization prospects; and the preparation process of the prefabricated laminated slab is simple to operate, and the production and processing efficiency of the prefabricated laminated slab is ensured.

Description

technical field [0001] The invention relates to the technical field of building floor heating engineering, in particular to a prefabricated laminated board suitable for laying floor heating pipelines and a preparation process. Background technique [0002] With the rapid development of the economy and the improvement of people's living standards, along with the increasing demand for materials, the development of my country's construction industry has also advanced by leaps and bounds. More and more laminated floors are used in high-rise buildings and large buildings. In bay buildings, laminated floor slabs are assembled integral floor slabs formed by laminating prefabricated slabs and cast-in-place reinforced concrete layers. It has the advantages of good integrity, flat upper and lower surfaces of the slab, and is convenient for decoration. [0003] The Chinese invention patent with the application number CN201210592784.2 discloses a prefabricated laminated slab with reinfor...

AI Technical Summary

Problems solved by technology

[0005] (1) The production and processing of plywood needs to be carried out in stages, resulting in waste of manpower and high personnel costs;

[0006] (2) The concrete is not solidified when the pin is inserted, and the pin is easily skewed and the verticality cannot be guaranteed;

[0007] (3) There are large particle size aggregates in the concrete. In order to avoid large particle size aggregates when inserting the pins, the insertion depth cannot be guaranteed;

[0008] (4) The pins on the laminated deck are easy to be trampled off at the construction site, and the repair needs to re-install the fixing pins of the expansion tube, which will cost a lot of labor and materials
