Technical Field

The invention relates to the technical field of assembly type buildings, in particular to a method for reserving a hole of a fan of a prefabricated plate of a roof.

Background

The fabricated steel structure building is one of main building structure types and is assembled and integrated by various prefabricated components, wherein steel components such as column beams and the like are processed and produced in a factory and are reliably connected and installed after being transported to a construction site, the fabricated steel structure building is simple to construct, green and environment-friendly, the construction period is greatly shortened, and the state is vigorously promoting the development of the fabricated steel structure building.

In the process of implementing the invention, the inventor finds that at least the following problems in the prior art are not solved: the method is easy in the process of manufacturing the prefabricated plate, the types of the prefabricated plate can be reduced, and the method is convenient for rapid production, but is not beneficial to the assembly field, a large amount of labor needs to be consumed for opening the hole, supporting the mold, binding reinforcing steel bars and pouring concrete, the labor cost of the construction field is usually about one third higher than that of a workshop, and the concrete also needs to be maintained for a certain time, so that the installation period is longer.

Therefore, a method for reserving a hole in a fan of the prefabricated roof slab is provided.

Disclosure of Invention

The invention aims to provide a method for reserving a hole in a fan of a prefabricated roof slab, which changes all work of a construction site into factory workshop manufacture, reduces labor cost compared with the manufacture in the construction site, and reduces the field construction time because concrete curing is finished in the workshop so as to solve the problems in the background technology.

The invention provides a reserved hole of a fan of a prefabricated roof slab, which comprises a steel frame beam and the prefabricated roof slab, wherein the prefabricated roof slab is of a U-shaped structure, the length of the outer surface of the upper end of the prefabricated roof slab is 200mm, the height of the prefabricated roof slab is 670mm, and the steel frame beam is arranged at the position, close to one side, of the outer surface of the lower end of the prefabricated roof slab.

A method for manufacturing a reserved hole of a fan of a prefabricated roof slab comprises the following steps:

s1: pouring a prefabricated roof slab in a factory;

s2: erecting a mould, binding reinforcing steel bars and pouring concrete at the hole of the prefabricated slab of the roof to manufacture a reserved hole of the fan;

s3: and maintaining the prefabricated roof slab and the reserved hole of the fan.

Compared with the prior art, the invention has the beneficial effects that:

the method for reserving the hole in the fan of the prefabricated roof slab comprises the steps of pouring the prefabricated roof slab in a factory, then erecting a formwork at the position of the hole, binding reinforcing steel bars and pouring concrete to manufacture the reserved hole in the fan, and then maintaining the prefabricated roof slab and the reserved hole in the fan.
