Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, to a pre-embedded junction box for building construction that can be sealed, reusable, precisely positioned, and quickly installed. Background Technology

[0002] In the pre-installation stage of electrical systems in building construction projects, the installation quality of pre-installed junction boxes directly affects the installation and use of subsequent electrical equipment.

[0003] Existing publication number CN217522539U discloses a portable electrical pre-embedded box device, relating to the technical field of pre-embedded boxes. It includes a box body, with a telescopic rod provided on the inner side wall of the box body. A No. 1 bolt is provided on one side of the box body, and the box body and the telescopic rod are fixed together by the No. 1 bolt. This portable electrical pre-embedded box device has a simple structure, is easy to use, has strong connectivity, facilitates the installation and maintenance of wiring, and improves the overall performance. The inventors discovered the following problems with the existing technology during the development of this utility model: During concrete pouring, due to the lack of an effective and precise positioning structure, junction boxes are easily displaced by the flow and vibration of concrete. This can lead to significant deviations in the position of electrical equipment rooms during later installation, affecting not only the overall aesthetics but also increasing construction costs and time due to the need for re-drilling holes, causing numerous inconveniences. Typically, the position of each junction box needs to be adjusted manually, and a large amount of auxiliary materials are used for fixing. The operation is cumbersome and time-consuming. Especially in large-scale building construction projects, this inefficient installation method can significantly extend the construction period and affect the project progress.

[0004] Therefore, in response to the above problems, a device for the precise positioning and rapid installation of pre-embedded junction boxes in building construction is proposed, which can be sealed, reused, and is quick to install. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a pre-embedded junction box for building construction that can be sealed, reusable, precisely positioned, and quickly installed, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pre-embedded wiring box for building construction that can be sealed, reusable, precisely positioned, and quickly installed, comprising a box body, with positioning rods fixedly installed on both sides of the inner wall of the box body, a guide through hole opened on the upper side of the positioning rod, an installation groove opened on the front side of the box body, a positioning piece detachably placed inside the installation groove, a limit gasket fixedly installed inside the box body, in addition, a conduit for wiring is evenly distributed and installed on the top of the box body, and an upper positioning plate is fixedly installed on the top of the box body, with a first transverse reinforcing bar inserted transversely inside the upper positioning plate, and a first longitudinal reinforcing bar placed above the first transverse reinforcing bar, the first transverse reinforcing bar and the first longitudinal reinforcing bar being fixed by binding wire.

[0007] Preferably, a fastening bolt is threaded on one side of the positioning piece. When the positioning piece is placed in the mounting groove on the front side of the box, the fastening bolt is screwed into the threaded hole on one side of the positioning piece. As the fastening bolt is screwed in, it will penetrate the positioning piece and extend into the interior of the box, where it will fit against a pre-set contact surface inside the box.

[0008] Preferably, the conduit is installed vertically through the top of the box, and the conduit mates with the mounting hole on the top of the box. After installation, the conduit not only stays on the top surface of the box, but also extends into the interior space of the box.

[0009] Preferably, a sealing gasket is provided on the top of the box body. The sealing gasket is fitted on the outside of the conduit. In the installed state, the inner wall of the sealing gasket is in contact with the outer surface of the conduit.

[0010] Preferably, a lower positioning plate is fixedly installed at the bottom of the box. During installation, a second transverse steel bar is inserted into the interior of the lower positioning plate, and a second longitudinal steel bar is fixedly placed at the bottom of the second transverse steel bar so that the two are perpendicular to each other. Finally, the second longitudinal steel bar and the second transverse steel bar are wrapped and fixed together using binding wire.

[0011] Preferably, a limiting through hole is provided in the upper area of ​​the positioning piece. At the same time, a front cover plate is detachably placed on the front side of the box body. A positioning through hole is provided at the corresponding position on the front side of the front cover plate. When the front cover plate needs to be installed, the positioning through hole can cooperate with the external fastener on the box body.

[0012] Preferably, when the front cover is placed at a designated position on the front side of the box, the positioning through hole on the front cover coincides with the limiting through hole above the positioning piece, and a positioning screw is installed in the internal thread of the positioning through hole.

[0013] The technical effects and advantages of this utility model are as follows: Compared with existing technologies, this pre-embedded junction box for building construction features a sealable, reusable, precise positioning, and rapid installation device. By setting positioning rods and guide holes on both sides of the inner wall of the box, a preliminary positioning benchmark is provided for the junction box during installation. The positioning plate, in conjunction with the fastening bolts, can be firmly installed on the front side of the box, and the limiting through holes on the positioning plate provide precise positioning for the subsequent installation of components. The upper and lower positioning plates are fixed to the transverse and longitudinal steel bars, respectively, forming a stable positioning frame, ensuring that the junction box will not shift during construction processes such as concrete pouring, greatly improving positioning accuracy.

[0014] Compared with existing technologies, this pre-embedded junction box installation device for building construction offers a quick and easy installation with precise positioning. It features rapid fixing via bolts, simplifying operation; a vertically inserted conduit runs through the top of the box, aligning with the mounting holes for swift installation; and a front cover plate, with its positioning holes aligning with the limiting holes on the positioning plate, is secured with positioning screws. The entire installation process requires no complex operations or large amounts of auxiliary materials, significantly reducing installation time and improving construction efficiency. Furthermore, the device is reusable, further reducing construction costs. Attached Figure Description

Detailed Implementation

[0020] 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.

[0021] Example 1 As attached Figures 1 to 4 The device shown is a pre-embedded junction box for building construction that can be sealed, reusable, precisely positioned, and quickly installed. It includes a box body 1, with positioning rods 2 fixedly installed on both sides of the inner wall of the box body 1. A guide hole 3 is opened on the upper side of the positioning rod 2. An installation groove 4 is opened on the front side of the box body 1. A positioning piece 5 is detachably placed inside the installation groove 4. A limiting gasket 7 is fixedly installed inside the box body 1. In addition, a conduit 8 is evenly distributed and installed on the top of the box body 1. An upper positioning plate 10 is fixedly installed on the top of the box body 1. A first transverse steel bar 11 is transversely inserted inside the upper positioning plate 10. A first longitudinal steel bar 12 is placed above the first transverse steel bar 11. The first transverse steel bar 11 and the first longitudinal steel bar 12 are fixed with binding wire.

[0022] Specifically: First, the positioning rods 2 on both sides of the inner wall of the box 1 and the upper guide through hole 3, together with the detachable positioning piece 5 in the installation groove 4, can accurately position the junction box according to different construction needs, ensuring the accurate installation position of the junction box; Second, it enables rapid installation, as the upper positioning plate 10 facilitates the horizontal insertion of the first transverse steel bar 11, and after placing the first longitudinal steel bar 12 on it, it is fixed with binding wire, making the operation simple and greatly improving installation efficiency; Third, it has stability, as the limiting gasket 7 inside the box 1 prevents the junction box from shifting, ensuring structural stability; Fourth, it facilitates cable arrangement, as the evenly distributed cable conduits 8 at the top provide an orderly channel for cables to enter and exit; Fifth, it is reusable, with a reasonable overall structural design, and each component can be reused, reducing construction costs and improving resource utilization.

[0023] Example 2 Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details: In a preferred embodiment, a fastening bolt 6 is threaded onto one side of the positioning piece 5. After the positioning piece 5 is placed into the mounting groove 4 on the front side of the box body 1, the fastening bolt 6 is screwed into the threaded hole on one side of the positioning piece 5. As the fastening bolt 6 is continuously screwed in, it will penetrate the positioning piece 5 and extend into the interior of the box body 1, where it will fit against the pre-set contact surface inside the box body 1, thereby firmly fixing the positioning piece 5 to the box body 1 and effectively preventing the positioning piece 5 from loosening or shifting during use.

[0024] As a preferred embodiment, the conduit 8 is a key channel for cable routing in the pre-embedded junction box device of the building. It is reasonably designed and firmly installed. The conduit 8 is installed vertically through the top of the box 1. The conduit 8 cooperates with the mounting hole on the top of the box 1 to ensure sealing and stability. After installation, the conduit 8 not only stays on the top surface of the box 1, but also extends into the internal space of the box 1, providing sufficient channels for subsequent cable laying, facilitating the insertion and exit of cables, and effectively protecting cables from interference and damage from the external environment.

[0025] In a preferred embodiment, a sealing gasket 9 is provided on the top of the box 1. The sealing gasket 9 has a specific shape and size to perfectly fit the installation requirements. The sealing gasket 9 is fitted on the outside of the conduit 8. In the installed state, the inner wall of the sealing gasket 9 is in contact with the outer surface of the conduit 8, forming a reliable sealing barrier. This effectively prevents external dust, moisture and other impurities from entering the box 1 through the gap between the conduit 8 and the top of the box 1, thereby providing good protection for the cables and other components embedded in the box 1 and ensuring the practical performance of the entire embedded junction box device.

[0026] In a preferred embodiment, a lower positioning plate 13 is fixedly installed at the bottom of the box body 1. The lower positioning plate 13 provides reliable support and positioning reference for the subsequent installation of reinforcing bars. During installation, a second transverse reinforcing bar 14 is inserted transversely into the interior of the lower positioning plate 13. A second longitudinal reinforcing bar 15 is fixedly placed at the bottom of the second transverse reinforcing bar 14 to ensure that its position is accurate and that the two are perpendicular to each other. Finally, the second longitudinal reinforcing bar 15 and the second transverse reinforcing bar 14 are wrapped and fixed together with binding wire to form a stable reinforcing bar structure, which further enhances the stability and firmness of the entire pre-embedded junction box device in building construction projects.

[0027] In a preferred embodiment, a limiting through hole 17 is provided in the upper area of ​​the positioning piece 5. The limiting through hole 17 can be adapted to specific positioning pins or bolts and other components to accurately limit the position. At the same time, a front cover plate 16 is detachably placed on the front side of the box body 1, which facilitates the inspection, maintenance and replacement of the internal components of the box body 1. A positioning through hole 18 is provided at the corresponding position on the front side of the front cover plate 16. When the front cover plate 16 needs to be installed, the positioning through hole 18 can cooperate with the external fasteners on the box body 1 to ensure that the front cover plate 16 can be accurately installed in the designated position, ensuring the stability and functionality of the entire device.

[0028] In a preferred embodiment, when the front cover plate 16 is placed at a designated position on the front side of the box body 1, the positioning through hole 18 on the front cover plate 16 coincides with the limiting through hole 17 above the positioning piece 5. The internal thread of the positioning through hole 18 is fitted with a positioning screw 19. At this time, the positioning screw 19 is aligned with the overlapping positioning through hole 18 and slowly screwed in. Since the positioning through hole 18 has a matching thread structure, the positioning screw 19 can be smoothly threaded into it. As the positioning screw 19 is continuously tightened, the front cover plate 16 is firmly fixed on the box body 1, ensuring the stability and integrity of the entire device structure.

[0029] In this embodiment, the box 1 is a commercially available device known to those skilled in the art. It can be customized or a model can be selected according to actual needs. Here we are just using it without making any structural or functional improvements, so we will not go into details here.

[0030] The working process of this utility model is as follows: First, the first transverse steel bar 11 is inserted transversely into the upper positioning plate 10 at the top of the box body 1, and the first longitudinal steel bar 12 is placed above it and fixed with binding wire; the second transverse steel bar 14 is inserted transversely into the lower positioning plate 13 at the bottom of the box body 1, and the second longitudinal steel bar 15 is placed at its bottom and made perpendicular to it, and then fixed with binding wire. Through the cooperation of the upper positioning plate 10 and the lower positioning plate 13 with the steel bars, the positioning frame is initially constructed.

[0031] Next, the positioning piece 5 is placed into the mounting groove 4 on the front side of the box 1, and the fastening bolt 6 is screwed in, so that it passes through the positioning piece 5 and extends into the interior of the box 1 to fit against the preset contact surface, thus completing the stable installation of the positioning piece 5. Next, the conduit 8 is vertically inserted into the mounting hole at the top of the box 1, extending into the interior space of the box 1. Simultaneously, a sealing gasket 9 is fitted onto the outside of the conduit 8, ensuring that the inner wall of the sealing gasket 9 fits against the outer surface of the conduit 8 during installation. Then, the front cover plate 16 is placed at the designated position on the front side of the box 1, so that the positioning through hole 18 on the front cover plate 16 coincides with the limiting through hole 17 above the positioning piece 5. A positioning screw 19 is threaded into the positioning through hole 18, completing the installation of the front cover plate 16. The above describes the working principle of this pre-embedded wiring box installation device for building construction, which allows for sealing, reusability, precise positioning, and rapid installation.
