Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and particularly relates to a pre-embedded wire box. Background Art

[0002] In building engineering, the application technology of concrete in wall columns is widely used, and it is necessary to pre-embed wire boxes in advance during the construction process. During the pre-embedding construction, it is necessary to ensure that the position of the pre-embedded wire box is accurate. Most importantly, it is necessary to ensure that no quality problems such as displacement and depression occur to the pre-embedded wire box after the structure is poured. The common method is to use a wire-passing pre-embedded wire box. A section of steel bar is inserted into the wire-passing holes on both sides of the pre-embedded wire box, and then the steel bar is tied to the steel bar mesh, and the pre-embedded wire box is fixed to the steel bar mesh by tying. Due to the complex external forces acting on the wall steel bar mesh during concrete pouring, this reinforcement will shift along with the shift of the steel bar mesh. Especially for a lightweight concrete wall with a single-layer steel bar mesh, the stability of the wire box cannot be guaranteed. A new type of pre-embedded wire box is disclosed in the Chinese patent with the publication number CN211396646U. Although the fixing device of its body can prevent front-back displacement, its disadvantage is that the left and right sides of the wire box cannot be connected to the wire pipes.

The processed steel bars are used as positioning steel bars 3 and inserted into the four hollow columnar fixing members 2; then they are tied to the wire mesh in the concrete wall with No. 22 binding wire. When the wall formwork is closed, the positioning steel bars are clamped to make the wire box stable and without looseness, which can effectively avoid the risk of the wire box being displaced during concrete pouring and ensure that the box opening is flush with the wall surface after the wall is formed.
