Description

Technical Field

[0001] This invention relates to the field of prefabricated building technology, and in particular to a method for installing electrical wiring between prefabricated walls and prefabricated stairs. Background Technology

[0002] In the construction of prefabricated concrete structures, some components such as walls, composite slabs, and stairs are produced in the factory and then transported to the construction site for assembly and installation. Different projects have different requirements for the assembly rate. In areas with high assembly rate requirements, walls, stairs, and floors often need to be prefabricated. Therefore, the accuracy and convenience of electrical wiring connections between prefabricated components are crucial. This is especially true for electrical wiring connections between prefabricated walls and prefabricated stairs with landing platforms. The landing platform is located at the vertical center of the prefabricated wall, and the light switches for the upper landing platform are on the lower wall. The wiring connection method raises concerns about operator safety, the ease of sealing the prefabricated control boxes, and potential quality issues after sealing.

[0003] Traditionally, a large through-hole is pre-drilled in the precast wall to provide sufficient space for electrical wiring to connect the precast wall and the precast staircase. Alternatively, a notch is left under the precast staircase, a conduit extends from the precast wall, and the two are connected at the notch. Both methods require wiring installers to work at heights, which is difficult and poses safety risks. Furthermore, additional formwork is needed when sealing the staircase and wall, which is time-consuming and labor-intensive. Summary of the Invention

[0004] In view of this, the purpose of this invention is to provide a method for installing electrical wiring between prefabricated walls and prefabricated stairs to solve the above problems.

[0005] To achieve the above objectives, the present invention provides a method for installing electrical wiring between prefabricated walls and prefabricated stairs, comprising the following steps: S1. In the process of detailed design of prefabricated components and production of prefabricated stairs, a first electrical conduit, a light box and a first operating box are reserved in the rest platform of the prefabricated stairs. Two first electrical conduits are provided. One end of the first electrical conduit is connected to the light box, which is located on the lower surface of the rest platform. The other end of the first electrical conduit is extended into the first operating box, which is located on the upper surface of the rest platform at the end of the stair section away from the prefabricated stairs.

[0006] S2. In the process of detailed design of prefabricated components and production of prefabricated walls, a second operating box, a second electrical conduit and a third electrical conduit are reserved in the prefabricated wall. The second operating box is set at the installation position of the prefabricated staircase on the side wall of the prefabricated wall. The second electrical conduit and the third electrical conduit are respectively set above and below the second operating box, and the ends of the second electrical conduit and the third electrical conduit extend into the second operating box.

[0007] S3. Install prefabricated stairs and prefabricated walls, and make the first control box and the second control box connected.

[0008] S4. Connect the ends of the two first electrical conduits to the ends of the second electrical conduits and the third electrical conduits, respectively.

[0009] S5. Use the same micro-expansion concrete as that used in the production of precast walls to seal the first and second operating boxes, and complete the installation of electrical wiring between the precast walls and the precast stairs.

[0010] Compared with existing technologies, the advantages of this invention are as follows: both the first and second operating boxes are located above the rest platform. During the later sealing process, only micro-expansion concrete of the same grade as the precast wall material needs to be used for smoothing, eliminating the need for formwork, reducing material usage, and avoiding the drawbacks of workers having to climb to heights. The sealing location is on the surface of the rest platform, avoiding the risk of the seal falling and improving safety. Furthermore, the sealing location can be aesthetically pleasing by applying a decorative layer to the surface of the rest platform, improving the appearance of the component and greatly adapting to current work requirements.

[0011] Furthermore, in S2, the ends of the second and third electrical conduits extend into the second operating box, specifically: the ends of the second and third electrical conduits are inserted into the second operating box from both ends until they reach the inner wall of the other end of the second operating box. Sufficient length of the second and third electrical conduits is left inside the second operating box to allow for free cutting during subsequent installation and wiring, ensuring connection with the first electrical conduit.

[0012] Furthermore, when installing prefabricated stairs and prefabricated walls in S3, the upper surface of the second operating box is made to be at the same height as or higher than the upper surface of the first operating box.

[0013] Furthermore, in S4, the ends of the two first electrical conduits are connected to the ends of the second and third electrical conduits respectively. Specifically, the ends of the first, second, and third electrical conduits are cut respectively; the wire ends of the two first electrical conduits are connected to the wire ends of the second and third electrical conduits respectively; and the conduit ends of the two first electrical conduits are connected to the conduit ends of the second and third electrical conduits respectively using a bend.

[0016] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0017] like Figures 1 to 4 As shown, the present invention proposes a method for installing electrical wiring between prefabricated walls and prefabricated stairs, which is carried out according to the following steps: S1. During the detailed design of prefabricated components and the production of prefabricated stairs, a first electrical conduit 2, a light box 1, and a first operating box 3 are pre-installed in the rest platform 9 of the prefabricated stairs. Two first electrical conduits 2 are provided, with one end connected to the light box 1, which is located on the lower surface of the rest platform 9. The other end of the first electrical conduit 2 is extended into the first operating box 3, with sufficient length of the first electrical conduit 2 left in the first operating box 3 for subsequent adjustment. The first operating box 3 is located on the upper surface of the rest platform 9 at the end away from the stair section 6 of the prefabricated stairs.

[0018] S2. During the detailed design and production of prefabricated wall 7 of the prefabricated components, a second operating box 8, a second electrical conduit 4, and a third electrical conduit 5 are pre-installed within the prefabricated wall 7. The second operating box 8 is positioned at the installation location of the prefabricated staircase on the side wall of the prefabricated wall 7. The second electrical conduit 4 and the third electrical conduit 5 are positioned above and below the second operating box 8, respectively. The ends of the second electrical conduit 4 and the third electrical conduit 5 extend into the second operating box 8, specifically: the ends of the second electrical conduit 4 and the third electrical conduit 5 are extended into the second operating box 8 from both ends until they reach the inner wall of the other end of the second operating box 8. Sufficient lengths of the second electrical conduit 4 and the third electrical conduit 5 are left inside the second operating box 8 for subsequent adjustments. The end of the second electrical conduit 4 is used to connect with the electrical conduit of the next layer of prefabricated wall 7, and the wire end of the third electrical conduit 5 is used to connect with the switch of the light box 1.

[0019] S3. Install the prefabricated stairs and prefabricated walls 7, connecting the first control box 3 and the second control box 8, ensuring that the upper surface of the second control box 8 is at the same height as or higher than the upper surface of the first control box 3. Generally, the upper surface of the second control box 8 is flush with the upper surface of the first control box 3. If the conduit diameter is large or the turning radius is large, appropriately increase the height of the second control box 8, making it slightly higher than the first control box 3, to appropriately increase the operating space and meet the turning radius requirements.

[0020] S4. Connect the ends of the two first electrical wires 2 to the ends of the second electrical wire 4 and the third electrical wire 5 respectively. Specifically, cut the ends of the first electrical wires 2, the second electrical wire 4 and the third electrical wire 5 respectively; connect the wire ends of the two first electrical wires 2 to the wire ends of the second electrical wire 4 and the wire ends of the third electrical wire 5 respectively; and use a bend to connect the conduit ends of the two first electrical wires 2 to the conduit ends of the second electrical wire 4 and the conduit ends of the third electrical wire 5 respectively.

[0021] S5. Use the same micro-expansion concrete as the precast wall 7 to seal the first operating box 3 and the second operating box 8, and complete the installation of electrical wiring between the precast wall 7 and the precast staircase.

[0022] Therefore, in this invention, both the first operating box 3 and the second operating box 8 are located above the rest platform 9. During the later sealing process, only micro-expansion concrete of the same grade as the precast wall 7 needs to be used for smoothing; no formwork is required, reducing material usage and eliminating the drawbacks of workers having to climb to heights. The sealing location is on the upper surface of the rest platform 9, avoiding the risk of the seal falling and improving safety. Furthermore, the sealing location can be aesthetically enhanced by a decorative layer laid on the upper surface of the rest platform 9, improving the appearance of the component and greatly adapting to the needs of current work.

[0023] The embodiments of this invention are intended to cover all such substitutions, modifications, and variations falling within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the scope of protection of this invention.
