Abstract
Description
Technical Field
[0001] This utility model relates to a lightweight concrete wall panel with a pre-embedded electrical conduit groove structure, belonging to the field of building component technology. Background Technology
[0002] Lightweight concrete wall panels are widely used in building construction due to their advantages such as light weight, high strength, and thermal insulation.
[0003] However, traditional wall panel wiring and junction boxes require on-site grooving, which is difficult to control in terms of precision, easily damages the wall panel structure, reduces its strength and stability, and is inefficient, generating noise and dust pollution that affects the construction environment and worker health. Pre-installing junction boxes directly on lightweight concrete wall panels during production is also difficult. Firstly, this requires customized design, production, and installation, significantly increasing design, production, and construction costs. Secondly, pre-installing junction boxes during production reduces the cross-sectional area and stiffness at these locations, making the wall panel prone to breakage during transportation.
[0004] Therefore, in order to solve the above-mentioned technical problems, it is indeed necessary to provide an innovative lightweight concrete wall panel with a pre-embedded electrical conduit groove structure to overcome the defects in the prior art. Utility Model Content
[0005] The purpose of this utility model is to provide a lightweight concrete wall panel that, when it is necessary to create a cable trough, only requires the construction worker to apply a horizontal hammering force to the lightweight concrete within the space enclosed by the embedded part of the cable trough, and the lightweight concrete within the enclosed space will fall off. If it is not necessary to create a cable trough, the lightweight concrete wall panel is no different from a conventional lightweight concrete wall panel without grooves.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a lightweight concrete wall panel with a pre-embedded electrical conduit groove structure, comprising a wall panel body and a pre-embedded electrical conduit groove on the wall panel body. The space enclosed by the pre-embedded electrical conduit groove can accommodate electrical wires. The pre-embedded electrical conduit groove has several holes that connect the enclosed space to the wall panel body. The pre-embedded electrical conduit groove extends horizontally along the length of the wall panel body or vertically along the height of the wall panel body. Both ends of the pre-embedded electrical conduit groove penetrate the corresponding end faces of the wall panel. The exposed surface of the pre-embedded electrical conduit groove is flush with the exposed surface of the wall panel body.
[0007] By adopting the above technical solution, the lightweight concrete within the space enclosed by the top, sides, and bottom surfaces of the embedded conduit groove is regularly bonded to the lightweight concrete outside the enclosed space only at the holes. Therefore, the lightweight concrete within the enclosed space can be horizontally broken at the holes under a certain horizontal external force, allowing for easy removal of the entire lightweight concrete within the enclosed space. After the lightweight concrete wall panel is installed on the construction site, if a wire trough needs to be created, the construction worker only needs to apply a horizontal hammering force to the lightweight concrete within the enclosed space of the embedded conduit groove, causing the lightweight concrete to detach and leaving a neat wire trough. When the lightweight concrete wall panel is installed on the construction site and no wire trough is needed, the lightweight concrete wall panel is no different from a conventional lightweight concrete wall panel without grooves. Therefore, by pre-embedding electrical conduit grooves at the most likely locations for wire grooves, lightweight concrete wall panels can not only achieve standardized and efficient production of concrete wall panels in the factory, but also enable the efficient installation of wire grooves on the construction site as needed, while ensuring construction quality and significantly reducing on-site noise and dust.
[0008] The lightweight concrete wall panel of this utility model with a pre-embedded conduit groove structure is further configured such that the cross-section of the pre-embedded conduit groove is U-shaped.
[0009] The lightweight concrete wall panel of this utility model with a pre-embedded conduit groove structure is further configured such that the pre-embedded conduit groove component is composed of a top plate, a side plate and a bottom plate, forming a U-shaped cross section.
[0010] The lightweight concrete wall panel of this utility model with a pre-embedded electrical conduit groove structure is further configured such that: holes are opened on the top panel, side panel and bottom panel.
[0011] The lightweight concrete wall panel of this utility model with a pre-embedded electrical conduit groove structure is further configured such that the holes occupy more than one-third of the area of the top panel, side panel and bottom panel.
[0012] By adopting the above technical solution, it is convenient for concrete outside the enclosed space of the embedded part of the conduit trench to flow into the enclosed space during pouring.
[0013] The lightweight concrete wall panel of this utility model with a pre-embedded electrical conduit groove structure is further configured such that the holes are arranged at regular intervals.
[0014] The lightweight concrete wall panel of this utility model with a pre-embedded electrical conduit groove structure is further configured such that the exposed edges of the top and bottom surfaces of the pre-embedded electrical conduit groove are flush with one side surface of the wall panel body.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] 1. The lightweight concrete wall panel with a pre-embedded conduit channel structure of this utility model has holes arranged at regular intervals on the top, side, and bottom plates of the pre-embedded conduit channel. This allows the lightweight concrete wall panel to be regularly bonded to the lightweight concrete outside the space enclosed by the top, side, and bottom surfaces of the pre-embedded conduit channel, only at the hole locations. Under a certain horizontal external force, the lightweight concrete inside the space enclosed by the pre-embedded conduit channel can be horizontally broken at the hole locations, thereby allowing the lightweight concrete inside the space enclosed by the pre-embedded conduit channel to be easily removed as a whole.
[0017] 2. After the lightweight concrete wall panel with the pre-embedded conduit groove structure of this utility model is installed on the construction site, if it is not necessary to open the conduit groove, the lightweight concrete wall panel is no different from the conventional lightweight concrete wall panel without groove.
[0018] 3. The lightweight concrete wall panel with pre-embedded conduit groove structure of this utility model can not only realize the standardized and efficient production of concrete wall panels in the factory, but also realize the efficient opening of conduit grooves on the construction site as needed, while ensuring construction quality and greatly reducing on-site noise and dust.

[0022] Please refer to the instruction manual appendix. Figure 1 To be continued Figure 3 As shown, this utility model is a lightweight concrete wall panel with a pre-embedded conduit groove structure, comprising a wall panel body 1 and a conduit groove pre-embedded component 2. The enclosed space of the conduit groove pre-embedded component can accommodate electrical conduits.
[0023] The cross-section of the wire conduit trench embedded part 2 can be C-shaped or U-shaped, etc. As a preferred embodiment, the wire conduit trench embedded part 2 is composed of a top plate 21, a side plate 22 and a bottom plate 23, forming a C-shaped structure. The C-shaped structure is a rectangular structure with an opening on one side.
[0024] The top plate 21, side plates 22, and bottom plate 23 are provided with a number of holes 24 arranged at regular intervals. The area of the holes 24 is not less than one-third of the area of the top surface 21, side surface 22, and bottom surface 23. The design of the holes 24 facilitates the flow of concrete outside the enclosed space of the embedded parts of the electrical conduit groove into the enclosed space during pouring.
[0025] The embedded part 2 of the electrical conduit groove can extend horizontally along the length direction of the wall panel body 1 or vertically along the height direction of the wall panel body 1. Both ends of the embedded part 2 of the electrical conduit groove penetrate the corresponding end face of the wall panel body 1. The exposed edge 211 of the top surface 21 and the exposed edge 231 of the bottom surface 23 of the embedded part of the electrical conduit groove are flush with one side surface of the wall panel body 1.
[0026] During the production of the wall panel body 1, lightweight concrete 11 is injected into the space enclosed by the top surface 21, side surface 22 and bottom surface 23 of the embedded part of the electrical conduit groove together with the wall panel body 1 to form a whole.
[0027] The working principle of the lightweight concrete wall panel with embedded electrical conduit groove structure of this utility model is as follows:
[0028] First, the exposed edges 211 of the top surface 21 and 231 of the bottom surface 23 of the embedded part 2 are flush with one side surface of the wall panel body 1. Then, lightweight concrete 11 is injected into the enclosed space of the embedded part 2 to form a whole, thus completing the production of the lightweight concrete wall panel. If it is necessary to open the wire groove, the construction worker only needs to apply a horizontal hammering force to the lightweight concrete 11 in the enclosed space of the embedded part 2, and the lightweight concrete 11 in the enclosed space will fall off. If it is not necessary to open the wire groove, the lightweight concrete wall panel is no different from the conventional lightweight concrete wall panel without grooves.
