Problems solved by technology

[0002] At present, my country's building floors basically use cast-in-place slabs, but the quality of cast-in-place slabs is not the most reliable as some people imagine. There are many factors that affect the quality of the floor slab. If there is a problem in one of the links, the floor slab will crack. At the same time, the design and construction of the concrete mix ratio and unreasonable maintenance measures will affect the quality.

Embodiment 1

[0042] Embodiment 1: Industrial production of high-efficiency prefabricated building floor slabs and production methods, as attached figure 1 - attached Figure 24 As shown, it includes a floor body 1 that can be connected with columns 20 and beams 30. It is characterized in that: the longitudinal cross section of the floor body 1 is trapezoidal; The steel head 4 is formed on the wall and protrudes from the side wall; welding holes are arranged on the trapezoidal end surface of the floor body 1, and the steel bar head 4 located on the trapezoidal end surface is exposed from the welding hole.

[0043] The floor body 1 is a hollow structure with several holes 5 .

[0044] The reinforcement frame is a double-layer structure, including an upper layer 2 and a lower layer 3; on the trapezoidal end face of the floor body 1, a steel bar 6 is arranged between the corresponding steel bar heads 4 in the upper layer 2 and the lower layer 3 to connect.

[0045] Between the slabs, the con...

Embodiment 2

[0053] Embodiment 2: The manufacturing method of the present invention's factory-produced high-efficiency prefabricated building floor slab and its manufacturing method. After the floor slab is placed on the beam, the exposed steel bars at both ends of the floor slab and the embedded iron or reserved steel bars on the beam are welded and fixed; the floor slab and The horizontal connection of the floor and the horizontal connection between the floor and the beam are connected and fixed by welding the exposed steel bars; the outermost horizontal exposed steel bar head of the floor is welded and fixed with the embedded iron or reserved steel bar on the beam.

[0054] The connection gaps between floor slabs and floor slabs and beams shall be filled with concrete materials.

[0055] The present invention is a novel high-strength prefabricated prefabricated floor slab (hereinafter referred to as "this product" or "floor") produced in a factory, and can be matched with a new type of h...

Abstract

The invention relates to a novel industrialized production efficiently-assembled type building floor slab. The novel industrialized production efficiently-assembled type building floor slab comprises a floor slab body capable of being connected with a column and a beam, and the longitudinal cross section of the floor slab body is trapezoid; a rebar support is embedded, the ends of the rebar support extend to the four lateral walls of the floor slab body and protrude out of the lateral walls to form rebar heads; welding hole slots are formed in the trapezoid end face of the floor slab body, and the rebar heads located on the trapezoid end face are exposed out from the welding hole slots. As the novel industrialized production efficiently-assembled type building floor slab is prefabricated in a plant, the quality can be better guaranteed; assembling and installation are achieved on site so that a large number of formworks can be saved, and the construction period can be shortened; only three main working procedures including placing the floor slab in place, mutual welding and joint filling are needed on the engineering construction site, and construction is convenient.

Description

technical field [0001] The invention relates to a building material, in particular to a factory-produced high-efficiency assembled building floor slab and a manufacturing method thereof. Background technique [0002] At present, my country's building floors basically use cast-in-place slabs, but the quality of cast-in-place slabs is not the most reliable as some people imagine. There are many factors that affect the quality of the floor slab. If there is a problem in one of the links, the floor slab will crack. At the same time, the design and construction of the concrete mix ratio and unreasonable maintenance measures will affect the quality. Contents of the invention [0003] The main purpose of the present invention is to provide a factory-produced high-efficiency prefabricated building floor slab and a manufacturing method that can be prefabricated in a factory, have stable quality, and can be installed quickly on site. [0004] Another object of the present invention ...
