Problems solved by technology

[0004] However, the inventor of the above structure believes that the prefabricated floor is manufactured by the factory and then transported to the construction site. The upper steel bars outside the prefabricated floor and the upper half of the outrigger group will be corroded by rainwater, thereby causing rust on the surface of the truss steel bars. Affects the later strength of the slab

Embodiment 1

[0043] The embodiment of this application discloses a prefabricated concrete floor slab, refer to figure 1 and figure 2, including a plurality of interconnected prefabricated bottom slabs 1, the prefabricated bottom slab 1 is provided with a steel mesh 2, and the steel mesh 2 is connected with truss bars 3, after the prefabricated bottom slabs 1 are connected to each other at the construction site, the part of the truss steel bars 3 is formed by the prefabricated bottom slab 1 The upper surface of the truss bar 3 protrudes, and is used to erect the upper steel bar 4 above the truss bar 3, so that the truss bar 3 can play a supporting role in the process of erecting the upper bar bar 4, which facilitates the setting of the upper bar bar 4. The cast-in-place layer 5 is formed by pouring concrete on the upper surface of the prefabricated bottom slab 1, the upper steel bar sheet 4 is located in the cast-in-place layer 5, and the truss steel bars 3 protruding from the upper surfac...

Embodiment 2

[0050] This embodiment discloses a production method of an assembled prefabricated concrete floor slab, referring to Figure 8 , the difference from Embodiment 1 is that: before the prefabricated floor 1 is poured, a reusable air support assembly 9 is installed in the installation sleeve 6, the air support assembly 9 includes an outer support body 91 and an air bag 92, and the outer support body 91 is a multi-lobed structure, the airbag 92 is cylindrical, and the outer support body 91 of multi-lobe structure is wrapped on the airbag 92 to support the shape of the airbag 92, and the airbag 92 can block the inside of the outer support body 91 to reduce the mortar entering Inside the outer support body 91 . After the outer support body 91 is connected to the installation sleeve 6, the air bag 92 is filled with gas, and then the prefabricated bottom plate 1 is poured, and then when the strength of the prefabricated bottom plate 1 reaches 30%, the gas in the air bag 92 is released,...

Abstract

The invention relates to the technical field of assembly type building floor slabs, in particular to an assembly type prefabricated concrete floor slab which comprises a plurality of prefabricated bottom plates, and reinforcing meshes are arranged in the prefabricated bottom plates; truss steel bars are connected to the steel bar net and comprise upper-layer steel bars and supporting leg steel bars; a mounting sleeve is fixedly arranged on the reinforcing mesh; mounting holes are reserved in the positions, corresponding to the mounting sleeves, of the prefabricated bottom plate; one end of the supporting leg steel bar is detachably connected with the mounting sleeve, and the other end is used for mounting an upper-layer steel bar. The assembly type building floor slab has the effect of reducing rusting of the truss steel bars arranged on the prefabricated bottom plate. Meanwhile, the invention further discloses a production method of the assembly type building floor slab.

Description

technical field [0001] The present application relates to the technical field of an assembled building floor, in particular to an assembled prefabricated concrete floor and a production method. Background technique [0002] Prefabricated buildings refer to buildings that are processed and manufactured in factories, such as floor slabs, wall panels, stairs or balconies, transported to the construction site, and assembled and installed on site through reliable connections. Prefabricated concrete floors are widely used in prefabricated buildings, which can reduce the use of formwork and improve construction efficiency. [0003] The patent document with authorized notification number CN207988292U discloses a prefabricated laminated floor, including a prefabricated floor and truss reinforcements arranged along the length direction of the prefabricated floor, a reinforcement mesh is arranged in the prefabricated floor, and the truss reinforcement includes a prefabricated floor abo...
