Description

Technical Field

[0001] This invention relates to the field of building engineering technology, and more specifically, to a rebar-connecting junction box with adjustable installation position and its usage method. Background Technology

[0002] In building construction or various decoration projects, junction boxes are indispensable electrical auxiliary tools. They are mainly used for the installation of switch, socket and other electrical appliance wiring panels, and also serve the functions of wire connection, line transition and line safety protection. In order to ensure the cleanliness and beauty of the building surface, junction boxes are usually installed by pre-embedding.

[0003] In existing technology, the conventional design of a through-reinforcement junction box involves directly setting fixed through-reinforcement channels on two opposite sides of the box body. During construction, the wall and column reinforcement bars are passed through these channels to fix the junction box to the wall and column reinforcement frame. However, this type of junction box has obvious technical defects: Firstly, the position of the reinforcing bar hole is fixed and cannot be adjusted according to the actual construction. When there are differences in the thickness of the protective layer of the wall and column reinforcing bars, the junction box is difficult to install and may lead to deviation in the pre-embedded position. Secondly, if the outermost steel bars of the wall column are horizontal or vertical steel bars, the fixing duct cannot match the steel bar layout, requiring additional processing or replacement of the junction box, which reduces construction efficiency. Third, without precise positioning markers, construction workers can only rely on experience to determine the location of the reinforcing bars, making it difficult to guarantee the accuracy of the thickness of the reinforcing bar protective layer. After the concrete is poured and the formwork is removed, the junction boxes are easily obscured or not fully exposed, which seriously affects the quality of subsequent electrical construction and pre-embedded construction.

[0004] To address the aforementioned issues, there is an urgent need for a rebar-insertion junction box that allows for flexible adjustment of the rebar insertion position, precise positioning, and stable fixation, in order to adapt to different construction environments, installation requirements, and application scenarios, thereby improving the standardization and precision of the junction box pre-embedding construction. Summary of the Invention

[0005] In view of the technical defects of existing through-reinforcement wiring boxes, such as fixed through-reinforcement position, inability to adapt to different reinforcement protective layer thicknesses, low positioning accuracy, and limited application scenarios, the purpose of this invention is to provide an adjustable through-reinforcement wiring box and its usage method, so as to achieve precise adjustment of the through-reinforcement position, adapt to different wall and column reinforcement protective layer thicknesses and reinforcement arrangement forms, ensure that the box can be fully exposed after pre-embedding, improve the stability of the box fixation, simplify the construction operation process, expand the applicable scope of the box, and meet the electrical pre-embedding construction needs of various building projects.

[0006] On one hand, the present invention provides a recessed wiring box with adjustable installation position, comprising a box body and two movable reinforcing sliders, wherein, Anti-tipping teeth are provided on both opposite sides of the box body. A locking tooth adapted to the anti-tipping teeth is provided on the inner side of the movable rib-piercing slider. The movable rib-piercing slider slides along the rib-piercing side of the box body through the cooperation of the locking tooth and the anti-tipping tooth. Furthermore, the movable rib-piercing slider is configured to slide unidirectionally from the outside to the inside of the box body, and the movable rib-piercing slider can slide into one end of the rib-piercing side and slide out from the other end. The movable reinforcing bar sliding block is provided with reinforcing bar channels adapted to the wall column reinforcing bars; A dimension line is provided on the side of the reinforcing bar of the box body. The dimension line is used to read the installation position of the reinforcing bar and the thickness of the reserved reinforcing bar protective layer.

[0007] Alternatively, the anti-backflow teeth can be integrally molded with the box body.

[0008] Alternatively, the anti-backflow teeth can be a continuous strip-shaped tooth structure that extends along the length of the side of the reinforcing bar.

[0009] Alternatively, the two movable rib-threading sliders are respectively fitted onto the two rib-threading sides of the box body, and the sliding directions of the two movable rib-threading sliders are parallel to each other.

[0010] Alternatively, the dimension lines are distributed along the length of the side of the reinforcing bar, and the scale values ​​of the dimension lines are adapted to the standard dimensions of the concrete cover thickness.

[0011] Alternatively, the outer surface of the movable through-rib slider can be a smooth plane with rounded edges.

[0012] Alternatively, both the box body and the movable through-rib slider can be made of flame-retardant rigid engineering plastic.

[0013] On the other hand, the present invention also provides a method for using an adjustable-position through-reinforcement wiring box, for constructing the adjustable-position through-reinforcement wiring box as described above; the method includes the following steps: S1: Based on the required thickness of the concrete cover for the reinforcing bars in the construction wall columns, determine the target installation position of the movable reinforcing bar slider by using the dimension line on the side of the reinforcing bar wiring box. S2: Slide the movable rib-connecting slider from one end of the rib-connecting side, slide it inward along the anti-backward teeth to the target installation position, and use the cooperation of the locking teeth and the anti-backward teeth to achieve unidirectional positioning of the slider; S3: Insert the wall column steel bars into the steel bar insertion holes on the two movable steel bar insertion sliders, fix the steel bar insertion junction box to the steel bar frame of the wall column through the steel bars, and adjust the position of the steel bar insertion junction box so that the box body is close to the wall column formwork to complete the fixing of the junction box.

[0014] Alternatively, after securing the camera obscura, the following steps can be included: S4: Concrete pouring is carried out. After the formwork is removed, the wiring box is fully exposed, and the pre-embedded construction is completed.

[0015] Alternatively, if it is necessary to adjust the installation position of the junction box before pouring concrete in step S4, the movable through-bar slider can be slid out from the other end of the through-bar side, and steps S1-S3 can be repeated to complete the reinstallation and position adjustment of the slider.

[0016] As can be seen from the above technical solution, the adjustable-position through-reinforcement wiring box and its usage method provided by this invention, with its advantages of flexible adjustment of the through-reinforcement position, precise positioning, stable fixing, good weather resistance of the material, and convenient operation, can be widely used in the pre-embedded construction of electrical wiring boxes in various building projects. The beneficial effects of this invention are: 1. By matching the anti-tipping teeth of the box body with the locking teeth of the slider, the movable rebar sliding slider can slide along the rebar side of the box body, realizing flexible adjustment of the rebar position. It can adapt to walls and columns with different rebar protective layer thicknesses and different rebar arrangement forms, solving the technical defects of fixed rebar position in traditional boxes, improving the versatility of boxes, and expanding the application scenarios of boxes. 2. The movable through-bar slider adopts a one-way sliding design from the outside to the inside. It uses the engagement of the locking teeth and anti-tipping teeth to achieve one-way positioning, effectively preventing the slider from shifting during construction and improving the stability of the box fixing. At the same time, the slider can slide in from one end of the through-bar side of the box and slide out from the other end, which facilitates the reinstallation and position adjustment of the slider, reduces the cost of construction errors, and adapts to the needs of construction verification and position correction in various scenarios. 3. Set dimension lines on the side of the box body that match the standard size of the concrete cover thickness of the steel reinforcement. Construction personnel can directly read the precise installation position of the reinforcement through the dimension lines without additional measuring tools, so as to achieve accurate positioning of the reinforcement position, ensure that the reserved concrete cover thickness meets the construction specifications, and ensure that the box can be fully exposed after concrete pouring and formwork removal, thereby improving the quality of pre-embedded construction and meeting the requirements of various high-precision construction scenarios. 4. The anti-tipping teeth and the box body are integrally molded. Both the box body and the slider are made of flame-retardant hard engineering plastics, which have good structural strength and weather resistance. They can withstand the vibration and extrusion of concrete pouring and the corrosion of alkaline environment. At the same time, they meet the fire protection requirements of building electrical systems, extend the service life of the junction box, and are suitable for complex construction environments such as indoor, outdoor, humid, and densely reinforced concrete. 5. The method of using this invention is simple and convenient. Construction personnel can quickly complete the slider positioning, junction box fixing and position adjustment without complicated processing or auxiliary tools. It effectively improves the construction efficiency of the wiring junction box pre-embedding and reduces the construction difficulty. It is especially suitable for renovation and expansion projects, prefabricated buildings and other scenarios with high requirements for construction efficiency and accuracy.

[0026] To address the various shortcomings of existing wiring boxes, this invention provides an adjustable-position wiring box with through-ribs, primarily composed of a box body and two movable through-rib sliders. Anti-tipping teeth are cast into the two sides of the box body where through-ribs are to be installed. The movable through-rib sliders have retaining teeth whose dimensions match the anti-tipping teeth. The movable through-rib sliders can slide along the anti-tipping teeth on the box body, but can only slide from the outside to the inside of the box body; they cannot slide backward. The box body is engraved with dimensional lines, allowing direct reading of the through-rib installation position and the thickness of the reserved protective layer.

[0027] The following will provide a more detailed description of the adjustable mounting position wiring box of the present invention, in conjunction with the accompanying drawings and embodiments in different application scenarios.

[0028] To illustrate the structure of the adjustable-position wiring box and its usage method provided by the present invention Figures 1 to 6The specific structure of the through-rib wiring box with adjustable installation position according to an embodiment of the present invention is shown from different perspectives.

[0029] Example 1

[0030] Combination Figures 1-6 As shown in the figure, the adjustable mounting position wiring box provided in this embodiment includes a box body 1 and two movable wire-through sliders 2. The box body 1 is a hollow cuboid structure that is adapted to the installation size of conventional switches and sockets. The two opposite vertical sides of the box body 1 are wire-through sides. Both wire-through sides are integrally formed with anti-backward teeth 3. The anti-backward teeth 3 are continuous strip tooth structures that extend along the length of the wire-through side. The cross-section of the teeth is a right triangle with the right-angled side facing the inside of the box body 1 and the hypotenuse facing the outside of the box body 1.

[0031] The movable rib-piercing slider 2 is a rectangular block structure adapted to the side of the rib-piercing mechanism. Its inner side is machined with locking teeth 4 that are adapted to the anti-backward teeth 3. The tooth shape of the locking teeth 4 is completely fitted with the anti-backward teeth 3, so that the movable rib-piercing slider 2 can slide along the side of the rib-piercing mechanism of the box body 1 through the cooperation of the locking teeth 4 and the anti-backward teeth 3. Due to the structural design of the teeth, the movable rib-piercing slider 2 can only slide unidirectionally from the outside to the inside of the box body 1 and cannot move backward in the opposite direction, thus realizing the unidirectional positioning of the slider.

[0032] The movable rebar-threading slider 2 can slide into the top and out from the bottom of the rebar-threading side of the housing 1, facilitating disassembly and reinstallation of the slider; a circular rebar-threading channel 5 is provided in the middle of the movable rebar-threading slider 2, and the inner diameter of the rebar-threading channel 5 is similar to that commonly used in building construction. 8. 10. The outer diameter of the wall and column reinforcement bars is matched to ensure that the reinforcement bars can be smoothly inserted without excessive gaps.

[0033] The side of the box 1 with the reinforcing bar has a dimension line 6 printed on it. The dimension line 6 is linearly distributed along the length of the side of the reinforcing bar, and the scale value increases sequentially from 0. The scale unit is mm, and the scale value is compatible with the national standard dimensions of the thickness of the concrete cover of the reinforcing bar in building construction (such as 15mm, 20mm, 25mm, 30mm, etc.). Construction personnel can directly read the installation position of the movable reinforcing bar slider 2 and the reserved thickness of the concrete cover of the reinforcing bar through the dimension line 6.

[0034] The outer surface of the movable reinforcing bar slider 2 is a smooth plane with no protrusions on the contact surface with the wall and column formwork, which prevents grout from seeping in during concrete pouring. The four edges of the slider are all rounded with R2 to prevent scratches and jamming during construction. Both the box body 1 and the movable reinforcing bar slider 2 are made of flame-retardant rigid PVC plastic with a flame retardant rating of V0 and a compressive strength of ≥30MPa. It can withstand the vibration and extrusion of concrete pouring and is resistant to acid and alkali corrosion, making it suitable for the harsh environment of building construction.

[0035] Two movable reinforcing bar sliders 2 are respectively assembled on the two reinforcing bar sides of the box body 1, and the sliding directions of the two sliders are parallel to each other, ensuring that the coaxiality error of the two reinforcing bar channels 5 is ≤0.5mm, ensuring that the wall column reinforcing bars can be smoothly inserted into the two reinforcing bar channels 5, and improving the flatness of the fixed box.

[0036] The junction box in this embodiment can be directly applied to conventional construction scenarios such as residential buildings and public buildings, and is compatible with... 8. The 10mm horizontal or vertical reinforcing bars can meet the requirements of 15-30mm reinforcing bar protective layer thickness, making construction convenient and positioning precise.

[0037] Example 2

[0038] This embodiment provides a method for using the adjustable-position through-reinforcement wiring box described in Embodiment 1 above in a prefabricated construction scenario for residential buildings. It is applied to the pre-embedding construction of socket boxes in the precast shear wall section of prefabricated commercial housing. The precast shear wall is designed with a 25mm thick protective layer for the reinforcing steel bars, and the outermost surface of the wall column is vertical. The construction steps for 10mm rebar are as follows: S21: During the prefabrication stage of the precast shear wall, the construction personnel, based on the design requirement of 25mm steel reinforcement protective layer thickness for the shear wall, check the dimension line 6 on the side of the rebar passage of the box 1 and determine that the target installation position of the movable rebar passage slider 2 is at the 25mm mark of dimension line 6. S22: Slide the two movable rib-through sliders 2 into the top of the two rib-through sides of the box body 1 respectively, and slowly slide them along the anti-backward teeth 3 towards the inside of the box body 1 until the edge of the slider is aligned with the 25mm scale line of the dimension line 6. At this time, the locking teeth 4 and the anti-backward teeth 3 are tightly engaged, realizing the one-way positioning of the movable rib-through sliders 2, and the sliders do not shift or jam. S23: Vertically adjust the precast shear wall 10 steel bars are sequentially inserted into the through holes 5 on the two movable through-bar sliders 2, so that the wiring box is fixed to the steel frame of the shear wall by the vertical steel bars. The horizontal and vertical positions of the box are slightly adjusted so that the outer surface of the box body 1 is tightly fitted with the precast template of the shear wall without gaps, thus completing the fixing of the box. S24: Concrete pouring operation is carried out on the precast shear wall. During the pouring process, avoid direct impact of the vibrator on the junction box. After the precast shear wall is cured and formed, it is transported to the construction site for assembly. After demolding, the junction box is fully exposed without any obstruction or offset, and the pre-embedding construction of the junction box is completed.

[0039] In this embodiment, the junction box is precisely positioned using dimensional lines, adapting to the precision requirements of prefabrication in prefabricated buildings. This solves the adaptation problem of vertical reinforcement arrangement in prefabricated shear walls, eliminating the need for on-site adjustments and improving the construction efficiency of prefabricated buildings.

[0040] Example 3

[0041] This embodiment provides a method for using the adjustable-position reinforcing bar junction box described in Embodiment 1 above in the renovation and expansion of existing buildings. It is applied to the pre-embedding of switch boxes in newly added structural columns during the renovation of old residential buildings. The original wall protective layer thickness is 20mm, and the designed reinforcing bar protective layer thickness for the newly constructed structural column is 30mm. The outermost surface of the wall column is horizontal. 8. During the initial positioning of the reinforcing bars, a positional deviation was found, requiring adjustment of the protective layer thickness by 28mm. The construction steps are as follows: S31: Based on the design requirement of 30mm steel reinforcement protective layer thickness for the newly constructed structural column, the construction personnel checked the dimension line 6 on the side of the reinforcing bar of box 1 and determined that the target installation position of the movable reinforcing bar slider 2 was at the 30mm mark of dimension line 6. S32: Slide the two movable through-rib sliders 2 into the top of the two through-rib sides of the box 1 respectively, and slide them along the anti-backward teeth 3 to the inside of the box 1 to the 30mm mark. Use the cooperation of the locking teeth 4 and the anti-backward teeth 3 to achieve unidirectional positioning of the sliders. S33: The horizontal level of the newly constructed structural column 8. The reinforcing bars are inserted into two through-holes 5. The junction box is fixed on the reinforcing bar frame. After the initial adjustment, the position of the junction box is found to be deviated after verification. The thickness of the reinforcing bar protective layer needs to be adjusted to 28mm. S34: The construction worker slides the two movable through-rib sliders 2 out from the bottom end of the through-rib side of the box 1, rechecks the dimension line 6, determines the new target installation position as the 28mm mark, repeats steps S2-S3, slides the sliders to the 28mm mark and completes the positioning, and then levels the box. 8. Reinsertion is re-inserted into the reinforcing bar channel 5, and the position of the concealed box is adjusted so that the box body 1 fits tightly with the structural column formwork, thus completing the second calibration of the concealed box position. S35: Concrete pouring was carried out on the newly constructed structural columns. After demolding, the pre-embedded positions of the wiring boxes were accurate, fully meeting the construction requirements for the renovation of old residential buildings.

[0042] In this embodiment, the design of the junction box being readjusted by sliding out a slider can meet the needs of position verification and correction in renovation and expansion projects, solve the problem of inconsistent thickness of the protective layer between the original wall and the newly built wall column, eliminate the need to replace the junction box, and greatly improve the construction efficiency of renovation and expansion projects.

[0043] Example 4

[0044] This embodiment provides a method for using the adjustable-position reinforcing bar wiring box described in Embodiment 1 above in a municipal engineering bridge construction scenario. It is applied to the pre-embedded construction of lighting switch boxes in the anti-collision wall column of an urban bridge. The anti-collision wall column is designed with a 30mm thick protective layer for the reinforcing steel reinforcement. The construction environment is outdoor, and the wall column has dense and horizontally arranged reinforcing steel. The construction steps are as follows: S41: Based on the design requirement of 30mm steel reinforcement protective layer thickness for the bridge anti-collision wall column and the accuracy requirements of outdoor construction, the construction personnel checked the dimension line 6 on the side of the reinforcing bar of box 1 and determined that the target installation position of the movable reinforcing bar slider 2 was at the 30mm mark of dimension line 6. S42: Due to the dense steel bars in the anti-collision wall columns and the narrow construction space, the design of the rounded corners of the movable through-bar slider 2 is used to slide the slider into the bottom of the through-bar side of the box 1 and slide it inward along the anti-backward teeth 3 to the 30mm mark to achieve one-way positioning. The sliding process is smooth and adaptable to the operation requirements of narrow spaces. S43: Horizontal adjustment of the crash barrier post 10. Insert the steel bars into the two through holes 5 to fix the box on the steel bar frame. Adjust the position of the box so that the smooth outer surface of the box 1 is in close contact with the anti-collision wall template to prevent the grout from seeping in during outdoor concrete pouring, and complete the fixing of the box. S44: Concrete pouring operation is carried out on the bridge crash barrier columns. During the outdoor pouring process, the junction boxes are protected. After the concrete is formed, the formwork is removed, and the junction boxes are fully exposed. They are free from corrosion and misalignment, meeting the usage requirements of outdoor electrical facilities for municipal bridges.

[0045] In this embodiment, the dark box, with its weather resistance of flame-retardant rigid engineering plastic and the structural design of the slider, is suitable for construction scenarios in municipal bridges, such as outdoor areas, densely reinforced concrete, and confined spaces, ensuring the quality of pre-embedded construction and the safety of subsequent use.

[0046] The adjustable-position through-reinforcement wiring box provided by this invention has a reasonable structural design, strong versatility, wide application scenarios, and simple and convenient usage. It effectively solves the technical defects of traditional through-reinforcement wiring boxes, improves the accuracy and efficiency of electrical pre-embedded construction in various building projects, and is suitable for electrical wiring box pre-embedding construction in various scenarios such as residential buildings, public buildings, industrial buildings, municipal engineering, renovation and expansion projects, and prefabricated buildings.
