Description

Technical Field

[0001] The utility model relates to the technical field of assembled building components, in particular to an assembled floor slab with integrated wire tubes. Background Art

[0002] With the rapid development of the construction industry, a variety of new prefabricated floor slabs with excellent performance such as light weight and environmental protection have been widely used in the construction industry. In order to solve the problem of secondary grooving required for later circuit layout, an integrated floor slab with built-in circuits has been invented. The end of the circuit pipe is flush with the side of the floor slab, and the end part is fixed by concrete.

[0003] However, since the pipe openings on the sides of this type of integrated floor are fixed and of limited size, the pipe openings must be precisely aligned when assembling circuits between adjacent floor slabs, which places high demands on installation and results in reduced installation efficiency. Therefore, during the production stage, the floor slabs must also be laid strictly according to preset routes, which places high precision requirements on production standards and increases production cycles and costs.

[0004] In view of the above problems, the utility model provides an assembled floor slab with integrated wire tubes which is simple and quick to install. Utility Model Content

[0005] The utility model aims to provide an assembled floor slab with integrated wire tubes, which reduces production and construction costs and realizes simple and quick installation.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an assembled floor with integrated wire pipe, comprising a floor body and a steel mesh, wherein the steel mesh is located inside the floor body and its ends extend to the surroundings and pass through the floor body, and the surface of the floor body is provided with at least one connecting hole connected to the line pipe, and the floor body is preset with a line pipe, and the floor body is provided with a plurality of inner grooves on its side, and the free end of the line pipe passes through the floor body and is located in the inner groove.

[0007] The principles and advantages of this solution are:

[0008] 1. In actual application, the utility model pre-buries the line pipe in the main body of the floor slab, and an inner groove is provided on the side of the main body of the floor slab. The free end of the line pipe passes through the main body of the floor slab and is located in the inner groove. Compared with the existing floor slabs in which the free ends of the pipes are all buried in concrete, the design of the inner groove in the utility model allows the free end of the line pipe to have a certain degree of freedom. When installing two adjacent floor slabs, it is only necessary to align the inner grooves with each other, and the line pipes at both ends can be properly adjusted to connect, which reduces the installation requirements and effectively improves the construction efficiency.

[0009] 2. In the utility model, the free end of the line pipe is located in the inner groove and can be adjusted according to the actual construction situation, which makes the installation more flexible, reduces the position accuracy requirements of the line pipe in the main body of the floor slab, increases the allowable position error range when laying pipes in the production process of the prefabricated floor slab, improves production efficiency, and effectively reduces production costs and later construction costs.

[0010] Furthermore, the inner groove has a groove width of not less than 180 mm and a groove depth of 180-220 mm.

[0011] The groove width in the above setting is not less than 180mm to facilitate the simultaneous arrangement of the ends of multiple line pipes according to the actual line layout requirements. The groove depth is 180-220mm to leave assembly margins for the line pipes in adjacent prefabricated floors without affecting the bearing area of ​​the floor slab, so as to facilitate flexible adjustment of the lines during actual layout, reduce assembly accuracy requirements, and improve construction efficiency.

[0012] Furthermore, the free end of the line duct is flush with the outermost surface of the floor slab body.

[0013] The free end of the line pipeline is flush with the outermost surface of the floor body, which effectively prevents the pipeline from being damaged by collision, extrusion and other damages that may occur during the construction process inside the floor, protects the integrity of the pipeline, and extends the service life of the pipeline.

[0014] Furthermore, the line pipeline radiates around the floor main body with the connection hole as the center to form multiple branch pipelines.

[0015] The above arrangement allows electrical appliances to be equipped with multiple line switches along multiple branch pipelines, making it convenient for residents to switch the electrical appliances on and off at different locations, effectively improving the convenience of life.

[0016] Furthermore, the steel mesh includes bottom reinforcement and surface reinforcement, and at least two sides of the bottom reinforcement protrude from corresponding sides of the floor slab body and extend outward, wherein the extension distance is 50-200 mm.

[0017] In the above setting, the extended part of the steel mesh is used to be placed on the beam or shear wall to support the prefabricated floor. At the same time, the end extension distance is set to 50-200mm to ensure that when adjacent prefabricated floor slabs are installed, the steel bars at the ends of the two floor slabs cooperate with the concrete poured on site, so that a continuous steel skeleton is formed between the adjacent floor slabs, and the overall structure is more stable.

[0018] Furthermore, at least two side edges of the bottom reinforcement are bent toward the surface reinforcement to form an L-shaped structure.

[0019] The above arrangement enables the ends of the steel mesh to form a tighter bond with the concrete during the concrete pouring process, thereby enhancing the bonding force between the steel bars and the concrete, improving the anchoring effect of the steel bars in the floor slab, and ensuring the overall stability of the floor slab structure.

[0020] Furthermore, a plurality of lifting units are provided on the floor main body, and the lifting unit includes a lifting assembly with one end pre-buried in the floor main body.

[0021] The above arrangement enables the hoisting equipment to lift the prefabricated floor slab through the lifting assembly, which facilitates transportation and installation and improves construction efficiency.

[0022] Furthermore, an arc-shaped groove is opened on the floor main body, and the upper end of the lifting assembly is located in the arc-shaped groove.

[0023] The above arrangement enables the upper end of the lifting assembly to be lower than the upper surface of the floor slab body, and there is no need to cut the protruding part of the lifting assembly after transportation and installation, thereby reducing the construction workload and improving the construction efficiency.
