Problems solved by technology

[0008] However, there are certain defects in the construction methods of the above-mentioned several floor slabs.
The first method requires a lot of cast-in-place operations, and the overall degree of assembly is low
The second method also requires certain cast-in-place operations, and at the same time, the assembly process is more complicated and the construction is more difficult.
The third method needs to use a large amount of I-beam, the overall steel consumption is relatively large, and the cost is relatively high

Embodiment 1

[0065] Such as figure 2 As shown, the prefabricated floor slab of this embodiment includes a load-bearing steel truss 2 and a lightweight concrete slab 1 , and the steel truss 2 is embedded in the lightweight concrete slab 1 .

[0066] The floor slab of this embodiment is also provided with connecting members for splicing. The connecting member in this embodiment is a mortise and tenon member, and the mortise and tenon member includes grooves 4 and flanges 3 arranged on both sides of the lightweight concrete slab 1 and matched with each other. For the present invention, all more than three hundred kinds of mortise and tenon structures in the prior art can be applied to the present invention.

[0067] This embodiment can be manufactured by using the manufacturing method designed in the present invention mentioned above. It is only necessary to make a slight improvement to step S5. In the step S5, when cutting the lightweight concrete blank, it is also necessary to complete ...

Embodiment 2

[0072] The prefabricated floor slab of this embodiment includes a load-bearing steel bar truss 2 and a lightweight concrete slab 1 , and the steel bar truss 2 is embedded in the lightweight concrete slab 1 . The lightweight concrete slab 1 is an autoclaved aerated concrete slab.

[0073] Such as Figure 3 ~ Figure 5 As shown, the steel bar truss 2 of this embodiment can adopt various structural forms.

[0074] First of all, for floors with low bearing performance requirements (such as the floor of the first floor), multiple straight steel bars can be directly configured as steel trusses.

[0075] Secondly, for middle and low-rise residential buildings, the load-carrying performance of the floor slabs has certain requirements, and reinforced structure steel trusses 2 can be used. Such as image 3 As shown, the steel truss 2 includes longitudinally arranged upper and lower chord main reinforcements 2a, and also includes web auxiliary reinforcements 2b arranged between the upp...

Embodiment 3

[0084] The prefabricated floor slab of this embodiment includes a load-bearing steel bar truss 2 and a lightweight concrete slab 1 , and the steel bar truss 2 is embedded in the lightweight concrete slab 1 . The lightweight concrete slab 1 is an autoclaved aerated concrete slab.

[0085] The steel bar truss 2 in this embodiment adopts the three-dimensional steel bar truss structure in the second embodiment.

[0086] In this embodiment, a connecting piece 5 is configured for conveniently connecting the floor slab with the beam 7 of the building.

[0087] Such as Figure 6 , Figure 7 As shown, the connecting piece 5 of this embodiment adopts bolt sleeves, and there are multiple bolt sleeves, and steel plates can be arranged on the top and bottom of the bolt sleeves to connect multiple bolt sleeves into one. This structure also facilitates the prefabrication of the bolt sleeves into the lightweight concrete slab 1 . With the above structure, the bolt sleeves can be welded an...

Abstract

The invention discloses a fabricated floor slab. The fabricated floor slab comprises a steel bar truss used for bearing and a light concrete slab, wherein the steel bar truss is embedded in the lightconcrete slab to ensure that the light concrete slab meets the bearing requirement. The invention further discloses a manufacturing method of the fabricated floor slab. The steel bar truss is accurately and fixedly placed in a concrete mold in a drill rod inserting fixing mode to achieve the purpose of implanting the steel bar truss into the light concrete slab. According to the fabricated floor slab and the manufacturing method thereof, on the premise that the bearing performance is met, complete integral prefabrication of the floor slab is achieved, the manufactured floor slab is low in weight, high in strength and easy to assemble, a steel structure frame does not need to be arranged in advance, the construction efficiency is greatly improved, and the construction cost is significantlyreduced.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to an assembled floor slab and a manufacturing method thereof. Background technique [0002] Prefabricated building refers to the transfer of a large number of on-site operations in the traditional construction method to the factory, where the building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory, and transported to the construction site. Reliable connections are assembled and installed on site. Compared with traditional buildings, prefabricated buildings have the advantages of less on-site cast-in-place operations, a higher degree of standardization, shorter construction periods, more in line with the requirements of green buildings, and more energy-saving and environmentally friendly. In recent years, my country has attached great importance to the development of the prefabricated constru...
