Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to an adjustable pre-embedded junction box. Background Technology

[0002] In cast-in-place concrete structure construction, the bottom positioning reinforcement of wall and column formwork affects the deviation of the structural member formwork, directly impacting the member's position and geometric dimensions. Traditional positioning methods primarily involve welding column positioning reinforcement, but welding positioning reinforcement and other positioning measures have the following technical drawbacks: In the construction of cast-in-place concrete structures, the installation of embedded junction boxes is affected by the accuracy of the horizontal reinforcement positions in the shear wall. If the horizontal reinforcement positions in the shear wall are misaligned, it will be difficult to ensure that the embedded junction box is properly positioned within the wall. Traditional junction box installation has the following technical defects: 1. The distance of the junction box from the wall cannot be adjusted; due to the design limitations of the junction box itself, the distance between the cross-bracing steel bar and the exposed surface of the junction box is fixed. Once the cross-bracing steel bar and the horizontal steel bar of the shear wall are fixed, the position of the junction box is also fixed and cannot be adjusted. If the horizontal steel bar of the shear wall itself deviates, the junction box cannot be installed at the correct distance from the wall.

[0003] 2. Quality defects: After the concrete is poured, if the junction box is not in the correct position, it may be covered by concrete. In this case, tools such as hammers will be used to pry, plan, and chisel to find the junction box, which will affect the appearance quality of the concrete wall.

[0004] 3. Cost issues: When the online box is covered by concrete and cannot be found, additional labor costs are required to locate the box, increasing labor expenses. Utility Model Content

[0005] Another technical problem to be solved by this utility model is to overcome the defects in the prior art, thereby providing an adjustable pre-embedded junction box, including: junction box, telescopic connector and fixed connector; One end of the telescopic connector is rotatably connected to the junction box, and the other end of the telescopic connector is rotatably connected to the horizontal steel bar of the shear wall. The telescopic connector is provided with a fixing hole. The junction box is equipped with a fixing connector, which is connected to the horizontal reinforcing bars of the shear wall.

[0006] Furthermore, the telescopic connector includes a first connecting plate and a second connecting plate; One end of the first connecting plate is slidably connected to the second connecting plate, the other end of the first connecting plate is rotatably connected to the junction box, and the other end of the second connecting plate is rotatably connected to a horizontal steel bar of a shear wall. Fixing holes are provided on both the first and second connecting plates.

[0007] Furthermore, a buckle is fixedly connected to the other end of the second connecting plate, and the buckle is rotatably connected to the horizontal reinforcing bars of the shear wall.

[0008] Furthermore, a rotating shaft is fixedly connected to the other end of the first connecting plate, and a top lug is provided on the wire box that is rotatably connected to the rotating shaft.

[0009] Furthermore, the second connecting plate is provided with a sliding groove, and the first connecting plate is slidably inserted into the sliding groove.

[0010] Furthermore, the fixed connector includes an internally threaded lug disposed on the wire box and a threaded rod threadedly connected to the internally threaded lug, the threaded rod being connected to the horizontal reinforcing bar of the shear wall.

[0011] Furthermore, the internal thread lugs are provided in pairs.

[0012] The adjustable embedded junction box provided by this utility model can be adjusted in position by setting a telescopic connector. Even if the horizontal reinforcement of the shear wall itself is deviated, the junction box can be installed at the correct distance from the wall by adjusting the position of the junction box. This avoids the need to dig, plan, and chisel the concrete after the concrete is poured because the junction box is covered by concrete. This ensures the appearance quality of the concrete wall and saves the labor cost of this part of the operation. Attached Figure Description

[0020] Please see Figures 1 to 2 An adjustable pre-embedded junction box includes: junction box 1, telescopic connector and fixed connector; One end of the telescopic connector is rotatably connected to the junction box 1, and the other end of the telescopic connector is rotatably connected to the horizontal reinforcing bar 7 of the shear wall. The telescopic connector is provided with fixing holes 8. The telescopic connector includes a first connecting plate 4 and a second connecting plate 5. One end of the first connecting plate 4 is slidably connected to the second connecting plate 5, and the other end of the first connecting plate 4 is rotatably connected to the junction box 1. The other end of the second connecting plate 5 is rotatably connected to a horizontal reinforcing bar 7 of the shear wall. Both the first connecting plate 4 and the second connecting plate 5 are provided with multiple sets of fixing holes 8. A buckle 6 is fixedly connected to the other end of the second connecting plate 5, and the buckle 6 is rotatably connected to the horizontal reinforcing bar 7 of the shear wall. A rotating shaft 3 is fixedly connected to the other end of the first connecting plate 4, and the junction box 1 is provided with a top cantilever 9 that is rotatably connected to the rotating shaft 3. A sliding groove is provided inside the second connecting plate 5, and the first connecting plate 4 is slidably inserted into the sliding groove.

[0021] A fixing connector is provided on the top of the junction box 1, and the fixing connector is connected to the horizontal steel bar 7 of the shear wall.

[0022] The fixed connection includes an internally threaded lug 2 set on the wire box 1 and a screw 10 threadedly connected to the internally threaded lug 2. The screw 10 is connected to the horizontal steel bar 7 of the shear wall.

[0023] The internal thread lugs are set in pairs.

[0024] The adjustable pre-embedded junction box provided by this utility model is used as follows: First, the internal threaded lug 2, the top lug 9 and the wire box 1 are integrally formed. Then, the first connecting plate 4 and the second connecting plate 5 are inserted and installed. The rotating shaft 3 on the first connecting plate 4 is matched with the top lug 9 on the wire box 1 for installation. Connect the clip 6 on the second connecting plate 5 to a horizontal steel bar 7 of the shear wall; select the corresponding fixing hole 8 on the first connecting plate 4 and the second connecting plate 5 according to the elevation of the junction box 1 and the actual position of the horizontal steel bar 7 of the shear wall; use 22# wire to pass through the selected fixing hole 8 at the same time, and tie the first connecting plate 4 and the second connecting plate 5 together to the horizontal steel bar 7 of the shear wall in the appropriate position. Screw the two screws 10 into the two internal thread lugs 2 respectively, so that the exposed length of the screws 10 + the internal thread lugs 2 = the thickness of the shear wall, so that the junction box 1 can be clamped from both sides when installing the shear wall template. Then, tie the screw 10 to the corresponding horizontal shear wall reinforcement 7. If there is no horizontal shear wall reinforcement 7 at this location, a separate horizontal shear wall reinforcement 7 needs to be set up, and the screw 10 is tied to this horizontal shear wall reinforcement 7.

Even if the horizontal reinforcement of the shear wall itself is deviated, the junction box can be installed at the correct distance from the wall by adjusting the position of the junction box. This avoids the need to dig, plan, and chisel the concrete after the concrete is poured because the junction box is covered by concrete. This ensures the appearance quality of the concrete wall and saves the labor cost of this part of the operation.
