Description

Technical Field

[0001] This utility model relates to building construction, and in particular to a pre-embedded junction box device. Background Technology

[0002] Building construction refers to the production activities during the implementation phase of an engineering project. It is the process of building various types of structures, or the process of turning the lines on design drawings into a physical object at a designated location. It includes foundation construction, main structure construction, roofing construction, and decoration construction.

[0003] During interior construction, to prevent electrical wire joints from getting damp, corroded, or damaged by foreign objects in the walls, it is necessary to introduce the wires into junction boxes through pre-embedded conduits. If the junction boxes are buried after the wall or concrete is poured, the structural surface needs to be cut, which may weaken the load-bearing capacity of the wall / beam and column, or even cause cracks or safety hazards. Therefore, it is necessary to use pre-embedded junction boxes.

[0004] Embedded junction boxes refer to junction boxes that are pre-embedded in walls or concrete structures. In existing technologies, embedded junction boxes have reinforcing bars fixedly installed on both sides. Reinforcing bars are then passed through the reinforcing bars and connected to the reinforcing bar cage, thus connecting the embedded junction box to the reinforcing bar cage. During formwork installation and concrete pouring, because the reinforcing bars are rigidly connected to the reinforcing bars, the impact force of concrete flow and vibration is directly transmitted to the junction box, which can easily lead to problems such as positional displacement and deformation. This affects subsequent conduit connections and equipment installation, and may even affect the flatness and aesthetics of the components, increasing later maintenance costs. Utility Model Content

[0005] To address the problem in the prior art where the rigid connection between the reinforcing bar box and the reinforcing bar results in the direct transmission of the impact force from concrete flow and vibration to the box, this utility model proposes a pre-embedded junction box device.

[0010] The front and rear ends of the connecting cylinder are fixedly connected with second elastic elements. The second elastic elements extend and retract laterally, and the second elastic elements contact the adjacent wall surfaces of the reinforcing box.

[0011] Preferably, the position adjusting component includes two connecting plates, both of which are guided and connected to the inner wall of the reinforcing box, and the two connecting plates are arranged facing each other vertically.

[0012] Each of the connecting plates is fixedly connected with a first elastic element, and the connecting cylinder is disposed between two first elastic elements. The near ends of the two first elastic elements are fixedly connected to the outer surface of the connecting cylinder.

[0013] The position adjustment component also includes a left and right extending strip-shaped sliding opening, a connecting rod, and a limiting plate. The strip-shaped sliding opening is opened on the outer surface of the rib-passing box and penetrates the inner wall of the rib-passing box. The strip-shaped sliding opening is vertically aligned with the connecting plate. The connecting rod is fixedly connected to the upper surface of the connecting plate, and the upper part of the connecting rod is slidably connected to the inside of the strip-shaped sliding opening.

[0014] The top of the connecting rod extends through a strip-shaped opening and is fixedly connected to a limiting plate, the width of which is greater than the width of the strip-shaped opening.

[0015] Preferably, the first elastic element is a vertically arranged spring, which is fixedly connected to the connecting plate, and the end of the spring away from the connecting plate is fixedly connected to the outer surface of the connecting cylinder.

[0016] Preferably, the second elastic element is a disc spring, and disc springs are fixedly connected to both the front and rear ends of the connecting cylinder, with the disc springs in contact with the inner wall of the reinforcing box.

[0018] Preferably, the reinforcing box has strip-shaped clearance openings on both the front and rear sides, and the strip-shaped clearance openings are vertically arranged;

[0019] The strip-shaped clearance is used to allow for vertical movement of the reinforcing bars.

[0020] The advantages of this invention are: during pouring, the deformation of the spring and disc spring can provide cushioning, preventing damage to the junction box body from the impact. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: This example aims to propose a pre-embedded junction box device.

[0027] according to Figure 1 — Figure 2 As shown, it includes a junction box body 1, a reinforcing box 3, a position adjusting component 4, a first elastic component, a second elastic component, and a connecting cylinder 6.

[0028] The main body of the junction box 1 is fixedly connected to the left and right sides of the reinforcing box 3.

[0029] The rib-threading box 3 is provided with a position adjustment component 4, which can move back and forth on the rib-threading box 3. A first elastic component is fixedly connected to the position adjustment component 4.

[0030] The position adjustment component 4 includes two connecting plates 404, both of which are guided and connected to the inner wall of the through-rib box 3, and the two connecting plates 404 are arranged vertically opposite each other; a first elastic element is fixedly connected to each of the connecting plates 404, the two first elastic elements are arranged opposite each other, the connecting cylinder 6 is arranged between the two first elastic elements, and the near ends of the two first elastic elements are fixedly connected to the outer surface of the connecting cylinder 6.

[0031] The adjusting component 4 also includes a horizontally extending strip-shaped sliding opening 401, a connecting rod 402, and a limiting plate 403. The strip-shaped sliding opening 401 is opened on the outer surface of the rib-piercing box 3 and penetrates the inner wall of the rib-piercing box 3. The strip-shaped sliding opening 401 and the connecting plate 404 are vertically corresponding. The connecting rod 402 is fixedly connected to the upper surface of the connecting plate 404, and the upper part of the connecting rod 402 is slidably connected to the inside of the strip-shaped sliding opening 401. The top of the connecting rod 402 protrudes from the strip-shaped sliding opening 401 and is fixedly connected to the limiting plate 403. The width of the limiting plate 403 is greater than the width of the strip-shaped sliding opening 401.

[0032] The first elastic element is a vertically arranged spring 5, which is fixedly connected to the connecting plate 404. The end of the spring 5 away from the connecting plate 404 is fixedly connected to the outer surface of the connecting cylinder 6. During casting, the deformation of the spring 5 generates a vertical buffering effect.

[0033] The second elastic element is a disc spring 7. Disc springs 7 are fixedly connected to both the front and rear ends of the connecting cylinder 6. Disc springs 7 are in contact with the inner wall of the reinforcing box 3. During casting, the deformation of disc springs 7 generates a lateral buffering effect.

[0034] The connecting steel bar is inserted into the connecting cylinder 6. During the pouring process, the impact force generated by the concrete pouring is buffered by the deformation of the elastic element. The steel bar is not easy to fall off the connecting cylinder 6. Therefore, it is only necessary to insert the connecting steel bar into the connecting cylinder 6 and fix it by the friction between the connecting cylinder 6 and the connecting steel bar.

[0035] A base plate 2 is fixedly connected to the bottom of the junction box body 1. The base plate 2 is made of flexible material. In this embodiment, the flexible material can be rubber, so that after being connected to the steel mesh, the direct friction between the junction box body 1 and the steel bar is reduced.

[0036] The reinforcing bar box 3 has strip-shaped clearance openings 8 on both the front and rear sides. The strip-shaped clearance openings 8 are set vertically and are used to avoid the vertical movement of the reinforcing bars.

[0037] Working principle: During the pouring process, the reinforcing bars are directly inserted into the connecting cylinder 6, then the reinforcing bars are welded to the reinforcing mesh, and then the concrete is poured.

[0038] During pouring, the concrete flow comes into contact with the main body 1 of the junction box, causing the main body 1 of the junction box to tend to displace, thereby compressing the spring 5 and the disc spring 7. After the pouring is completed, the main body 1 of the junction box returns to its original position under the action of the elastic potential energy of the spring 5 and the disc spring 7.

[0039] Therefore, the junction box body 1 can be connected to the steel mesh by a flexible connection instead of a rigid connection. When the casting process impacts the junction box, the spring 5 and disc spring 7 can provide cushioning, avoiding displacement and deformation problems caused by the rigid connection when it is impacted.

[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
