Description

Technical Field

[0001] This utility model relates to the field of embedded junction box installation technology, and in particular to a device for laying embedded junction boxes in shear walls. Background Technology

[0002] Pre-installation of electrical and plumbing components is an indispensable part of the construction process in building engineering. The quality of pre-installed junction boxes in shear walls is extremely important. Currently, there are two common methods for pre-installing junction boxes in shear walls: pre-installing foam boards or directly pre-installing the junction box.

[0003] However, the foam boards need to be removed later, and the broken foam flies around, affecting environmental hygiene and wasting labor and materials. Conventional pre-embedded junction boxes have a low finished product qualification rate due to reasons such as wire laying, junction box installation and formwork, resulting in rework, waste and increased costs. Rework also affects the quality of shear walls. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the existing technology of pre-embedded foam boards, which require foam removal later, resulting in broken foam flying everywhere, affecting environmental hygiene, and wasting labor and materials; conventional pre-embedded junction boxes have a low finished product qualification rate due to reasons such as wire laying, junction box installation and formwork, resulting in rework, waste, and increased costs; rework also affects the quality of shear walls. Therefore, a pre-embedded junction box laying device for shear walls is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a shear wall pre-embedded junction box laying device, including a reinforcing bar junction box, a template provided on the outside of the reinforcing bar junction box, a circular hole through the inner wall of the reinforcing bar junction box, a restraining reinforcing bar being connected through the upper and lower holes of the reinforcing bar junction box, a longitudinal reinforcing bar being provided below the restraining reinforcing bar, a vertical reinforcing bar being fixedly connected to the ground of the longitudinal reinforcing bar, a support plate being provided inside the reinforcing bar junction box, bolts being connected through both ends of the support plate, the bolts being threadedly connected to the threaded holes on the panel of the reinforcing bar junction box, a spring device being movably connected through the inner wall of the circular hole, a nut being threadedly connected to the front end of the spring device through the middle of the support plate, a reinforcing bar crossbeam being provided on one side of the restraining reinforcing bar, and the rear end of the spring device being fixedly connected to the outer wall of the reinforcing bar crossbeam.

[0006] Preferably, the spring device includes a threaded screw, a PVC conduit, a PVC cap, and a spring, with the PVC cap fixedly connected to one end of the threaded screw.

[0007] Preferably, the spring is disposed on the inner wall of the PVC conduit, the spring is sleeved on the outer wall of the threaded rod, and the PVC plug is fixedly connected to the outer wall of one end of the PVC conduit.

[0008] Preferably, the PVC conduit is movably sleeved on the outer wall of the spring.

[0009] Preferably, one end of the threaded screw is threadedly connected to the nut.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] This utility model facilitates installation. Based on design drawings, the spring device, support plate, and bottom opening of the junction box are mass-produced according to the drawings. Depending on whether a single junction box or multiple connected junction boxes are required, the restraining steel bars are cut, and the junction box can be pre-embedded for installation. After the civil engineering is completed, the concrete is poured and the formwork is removed, the internal threaded rod, nut, bolt, spring, and support plate of the spring device are removed, and the junction box pre-embedding work is completed. This utility model not only facilitates construction for workers, significantly improves the finished product qualification rate, and enhances the aesthetic appearance, but also effectively solves the problem of low qualification rate of pre-embedded junction boxes in shear walls, saves costs, and improves construction efficiency.

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1: As Figure 1 - Figure 5 As shown, this utility model provides a shear wall embedded junction box installation device, including a reinforcing cable box 1. A template 7 is provided on the outside of the reinforcing cable box 1. A circular hole 11 is provided through the inner wall of the reinforcing cable box 1. Restricting steel bars 2 are connected through the upper and lower holes of the reinforcing cable box 1. A longitudinal steel bar 8 is provided below the restraining steel bar 2. A vertical steel bar 9 is fixedly connected to the bottom surface of the longitudinal steel bar 8. A support plate 3 is provided inside the reinforcing cable box 1. Bolts 6 are threaded onto both ends of the support plate 3. On the threaded hole of the plate, a spring device 5 is movably connected through the inner wall of the round hole 11. The front end of the spring device 5 is threaded through the middle of the support plate 3 and connected to the nut 4. A steel crossbeam 10 is set on one side of the restraining steel bar 2. The rear end of the spring device 5 is fixedly connected to the outer wall of the steel crossbeam 10. The bottom of the junction box is opened. The two outermost junction boxes of the connected junction box are opened. The middle junction box does not need to be opened. The spring device 5 enters the junction box from the bottom of the box through the round hole 11. The junction box is installed according to the wall marking line. The junction box protrudes from the wall surface by 1.5cm-2cm.

[0021] The specific setup and function of this embodiment are described below. By pre-embedding the junction box 1, the junction box is restricted from displacement in five directions: up, down, left, right, and front. It can only move backward (inward into the wall), thus improving the installation quality of the junction box in the shear wall. A support plate 3 is installed inside the junction box, and a spring device 5 enters the box through a hole at the bottom. A front-end screw passes through the support plate 3 and is connected by a nut 4, further restricting the junction box from moving forward (towards the wall). When the shear wall panel is sealed, the template 7 presses the junction box from the outside in, causing it to move inward with the template 7. Under the action of the spring 504, it remains tightly fitted to the template 7. After the template 7 is removed, the junction box will be flush with the wall surface. The support plate 3, bolt 6, nut 4, screw, and spring 504 can be reused.

[0022] Example 2: Figure 1 - Figure 5 As shown, the spring device 5 includes a threaded rod 501, a PVC conduit 502, a PVC cap 503, and a spring 504. One end of the threaded rod 501 is fixedly connected to the PVC cap 503. The spring 504 is disposed on the inner wall of the PVC conduit 502 and is sleeved on the outer wall of the threaded rod 501. The PVC cap 503 is fixedly connected to the outer wall of one end of the PVC conduit 502. The PVC conduit 502 is movably sleeved on the outer wall of the spring 504. One end of the threaded rod 501 is threadedly connected to the nut 4.

[0023] The overall effect of this embodiment is that the spring device 5 is inserted into the junction box through the bottom hole, and the screw end passes through the support plate 3 and is fixed by the nut 4, which restricts the junction box to move outward, i.e., towards the wall. The front end of the spring device 5 abuts against the support plate 3, and the rear end of the spring device 5 is fixed to the wall plate reinforcement, so that the spring device 5 does not move. The junction box can move inward under the action of the template 7. Under the action of the spring 504, the junction box always stays in contact with the template 7.

[0024] The usage and working principle of this device are as follows: By pre-embedding the junction box 1, the junction box is restricted from moving in five directions (up, down, left, right, and front), but can move backward (inward into the wall), thus improving the quality of the pre-embedded junction box installation in shear walls. A support plate 3 is installed inside the junction box, and a spring device 5 enters the box through a hole at the bottom. A front-end screw passes through the support plate 3 and is connected by a nut 4, restricting the junction box from moving forward (inward towards the wall). When the shear wall panel is sealed, the template 7 presses the junction box from the outside in, causing the junction box to move inward with the template 7. Under the action of the spring 504, it remains tightly fitted to the template 7. After the template 7 is removed, the junction box will be flush with the wall surface. The support plate 3, bolt 6, nut 4, screw, and spring 504 can be reused.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
