Description

Technical Field

[0001] The utility model belongs to the field of construction engineering, in particular to a prefabricated floor component embedded wire box. Background Art

[0002] In construction projects, in order to meet the needs of society, the state encourages increasing the prefabrication rate of buildings, and the use of prefabricated components is becoming more and more common.

[0003] The existing patent authorization announcement number is CN216156921U, and the patent name is a utility model patent for a seepage-proof and water-stopping wire threading box for pre-embedded floor slabs. The patent records a wire threading box body that is cast synchronously with the floor slab, and water stop rings are respectively provided at the upper and lower ends of the wire threading box body. Water stop strips that can expand in contact with water in concrete are laid in the water stop rings; water stop wings that expand outward from bottom to top are provided around the water stop ring at the upper end, which are used to prevent water from leaking downward along the surface of the wire threading box body; a wire threading sleeve is provided in the wire threading box body between the upper and lower water stop rings, and the wire tube passes through the wire threading sleeve. When pouring concrete, the waterstop strip in the waterstop ring of the utility model expands after coming into contact with water in the concrete, and fills the gap between the wire box and the concrete tightly. The waterstop wing forms an umbrella-like structure to block the water flow and protect the wire pipe below. The waterstop coil also expands after coming into contact with water, which better controls the thickness of the wire pipe protective layer while absorbing part of the water to fill the gap between the wire pipe and the concrete, reducing the chance of leakage.

[0004] The device described in the above patent has certain drawbacks when in use. The embedded wire box on the floor of the prefabricated component is installed before the wire tube is laid, and the box connection direction cannot be preset according to the wire tube requirements. In addition, there are many truss bars in the component, and the initial wire tube design path often conflicts with the truss bars, resulting in the wire tube bending radius not meeting the specification requirements when the wire tube is connected to the wire box. There is stress in the connection between the wire tube and the wire box, which makes it impossible for the wires to pass smoothly in the later stage, resulting in reduced physical quality, increased labor and material costs, and failure to meet people's use requirements.

[0005] In summary, the existing pre-buried wire boxes have certain drawbacks when used and do not meet people's usage requirements. Therefore, we propose a pre-buried wire box for prefabricated floor components. Utility Model Content
