Abstract
Description
Technical Field
[0001] This application relates to the technical field of conduit construction, and in particular to a method for laying conduits in walls. Background Technology
[0002] Currently, based on the indoor wiring layout and the homeowner's renovation work, it is necessary to conceal the conduits, cable trays, and junction boxes within the walls to achieve the purpose of concealed wiring connections or the installation of electrical switches, sockets, and other components.
[0003] In the construction of electrical conduits in masonry structures, the construction method usually involves embedding the conduits by chiseling vertical grooves in the completed masonry wall. After the grooves are made, the conduits are laid in the grooves, and then the wall surface is repaired later to achieve the effect of concealed embedding and ensure the aesthetics of the interior.
[0004] However, during subsequent house maintenance, it was discovered that improper repair work on the grooved areas could cause cracks in the wall, affecting its aesthetics. Furthermore, chiseling the completed wall could lead to noise and dust pollution. Summary of the Invention
[0005] In order to maintain the construction environment and avoid the defects of wall cracks affecting the interior aesthetics, this application provides a method for laying concealed conduits in walls.
[0006] The technical solution for a wall-embedded conduit installation method provided in this application is as follows:
[0007] A method for concealed conduit installation in walls includes: S1, determining the opening position on the masonry block where the conduit will be installed, and making openings in the corresponding blocks; S2, constructing the masonry wall and placing the opened blocks in the corresponding positions to form a conduit embedment space; S3, before the masonry wall is capped, inserting the conduit into the reserved conduit embedment space and connecting it to the junction box in the junction box groove, with the junction box being fixed squarely and securely using masonry mortar.
[0008] By adopting the above technical solutions, the wall surface is effectively protected from damage caused by grooving after the wall construction is completed, ensuring structural safety, reducing pollution to the construction environment, avoiding the quality problem of easy cracking of the wall surface after grooving repair, and ensuring the aesthetics of the wall.
[0009] Optionally, in S2, when constructing masonry walls, mortar is spread between adjacent masonry blocks in the vertical direction, and a grout-blocking pipe is placed between the blocks with openings. A ring is fixed on the outer wall of the grout-blocking pipe, the outer diameter of the grout-blocking pipe is equal to the inner diameter of the opening on the block, and the thickness of the ring is less than the thickness of the spread mortar. The distance between the location of the ring and the end of the grout-blocking pipe is not less than the thickness of the spread mortar.
[0010] By adopting the above technical solution, the mortar spread during masonry will flow into the holes opened in the blocks, which will block the reserved space for pipelines. By placing a grout-blocking pipe between adjacent blocks with openings and setting up the ring on top of the blocks, the mortar will be blocked by the grout-blocking pipe, thereby ensuring that the reserved space for pipelines is unobstructed and providing a guarantee for the smooth insertion of subsequent pipelines.
[0011] Optionally, in S3, before the conduit is inserted into the reserved conduit pre-embedded space, a left ring plate and a right ring plate are fixed on the conduit. The left ring plate and the right ring plate cooperate to form a ring-shaped ring and are fastened to the outer wall of the conduit. A first ball is fixed on the left ring plate, a second ball is fixed on the right ring plate, and a third ball is provided at the junction of the left ring plate and the right ring plate. Each of the first ball, the second ball, and the third ball is provided with an elastic component. The elastic component is used to move the first ball, the second ball, or the third ball towards or away from the conduit.
[0012] By adopting the above technical solution, during the insertion of the conduit into the pre-buried space, due to the presence of the grout-blocking pipe and the conduit's own curvature, the end of the conduit will abut against the top of the grout-blocking pipe, thus causing the conduit insertion to be obstructed. The first, second, and third ball bearings, together with the elastic component, play a limiting and positioning role for the conduit, ensuring to a certain extent that the conduit is located in the exact center of the pre-buried space, thereby ensuring the smoothness of the conduit insertion process.
[0013] Optionally, the elastic component includes an inner rod, an outer tube, and a spring. One end of the outer tube is fixedly connected to the outer wall of the left or right ring plate. One end of the inner rod is inserted into the outer tube, and the other end is rotatably connected to the corresponding first, second, or third ball bearing. The spring is located inside the outer tube, with one end fixedly connected to the inner wall of the outer tube and the other end fixedly connected to the end of the inner rod.
[0014] By adopting the above technical solution, during the process of inserting the conduit into the pre-embedded space, the compression or release of the spring ensures that the first ball, the second ball, and the third ball are all in contact with the inner wall of the pre-embedded space, thereby achieving the effect of limiting and positioning the conduit. Because of the presence of the spring, it can pass smoothly even when encountering a slurry-blocking pipe, ensuring the smooth insertion of the conduit.
[0015] Optionally, the third ball bearing is provided with a locking assembly, which includes a rotating nut and a limiting rod. The outer wall of the outer tube at the third ball bearing is threaded. The rotating nut is sleeved on the outer tube at the third ball bearing and threadedly connected to the outer tube. The limiting rod is rotatably connected to the outer wall of the rotating nut, that is, the rotating nut rotates relative to the limiting rod. The outer tube at the third ball bearing is fixed on the left ring plate, and the right ring plate is provided with an insertion hole. The end of the limiting rod away from the rotating nut is inserted into the insertion hole. The ends of the left and right ring plates away from the third ball bearing are hinged.
[0016] By adopting the above technical solution, utilizing the existing structure of the locking component itself, and through the cooperation of rotating the nut and the external tube thread connection, the limiting rod is inserted into the insertion hole, thereby fixing the left and right ring plates. This fully utilizes the existing structure and achieves the closure of the left and right ring plates.
[0017] Optionally, a secondary plate is hinged to the right ring plate, with the hinge shaft set horizontally. The inner wall of the secondary plate is tightly attached to the outer wall of the right ring plate. The end of the outer tube at the second ball passes through the secondary plate and is threadedly connected to the right ring plate. A take-up groove is provided on the inner wall of the secondary plate, and a steel wire is stored in the take-up groove. One end of the steel wire is fixedly connected to the inner wall of the take-up groove.
[0018] By adopting the above technical solution, the sub-plate can be fully adapted to the working conditions, allowing two conduits to be inserted into one conduit pre-embedded space at the same time. The sub-plate and steel wire form a connection limit between the second conduit and the first conduit, ensuring that the two conduits can be smoothly inserted into the conduit pre-embedded space.
[0019] Optionally, the insertion hole extends through the sub-plate, and the steel wire is fixed to the take-up groove at the end of the sub-plate away from the insertion hole.
[0020] By adopting the above technical solution, the state of the steel wire wrapped around the conduit and then tied to itself is replaced. By limiting the position, the steel wire is fixed to the insertion hole after being wrapped around the conduit, which makes it easier for workers to tie.
[0021] Optionally, before use, the inner wall of the end of the grout-blocking pipe is chamfered, that is, the end face of the grout-blocking pipe is inclined inward towards its own center line.
[0022] By adopting the above technical solution, the chamfer setting makes it easier for the ball to slide into the grout-blocking pipe, reducing the impact of the grout-blocking pipe on the smoothness of the pipe insertion.
[0023] Optionally, the outer tube at the second ball bearing has a through hole through which a steel wire passes.
[0024] By adopting the above technical solution, the opening of the through hole ensures the utilization rate of the third ball and the elastic component at the third ball. By passing the steel wire through the through hole, the third ball can still play a supporting and limiting role for the conduit.
[0025] Optionally, the end of the outer tube at the second ball that is away from the second ball is tapered.
[0026] By adopting the above technical solution, in order to improve the stability of the outer tube and the conduit after the second ball bearing is fixed, the tip of the outer tube is rotated and inserted into the wall thickness of the conduit.
[0027] In summary, this application includes at least one of the following beneficial technical effects:
[0028] 1. The presence of the grout-blocking pipe overcomes the phenomenon that mortar will flow into the reserved space of the conduit during wall construction, ensuring the smoothness of conduit insertion.
[0029] 2. The first ball, second ball, third ball and elastic component provide support and limit for the conduit, preventing the conduit from abutting against the end of the slurry-blocking pipe and the conduit from being obstructed in the reserved space for insertion, thus ensuring the smoothness of conduit insertion.
[0030] 3. The sub-plate allows for the installation of two conduits instead of a single one, while ensuring smooth installation and improving construction efficiency. Attached Figure Description

[0038] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.
[0039] This application discloses a method for installing concealed conduit in walls.
[0040] To facilitate understanding, the components used in the construction will be explained first.
[0041] refer to Figure 1The conduit 2 is fixed with a left ring plate 4 and a right ring plate 5. Both the left ring plate 4 and the right ring plate 5 are arc-shaped plates with their concave surfaces facing each other. The ends of the left ring plate 4 and the right ring plate 5 that are close to each other are hinged, and the hinge axis is set vertically. The left ring plate 4 is provided with a first ball bearing 21 and a third ball bearing 23, and the right ring plate 5 is provided with a second ball bearing 22. The positions of the first ball bearing 21, the second ball bearing 22 and the third ball bearing 23 are arranged in a triangle, and each of them is provided with an elastic component 7. The presence of the elastic component 7 can make the first ball bearing 21, the second ball bearing 22 and the third ball bearing 23 move towards or away from the conduit 2, so that when the conduit 2 is inserted into the wall, it can limit the conduit 2, ensure the smoothness of the conduit 2 insertion, and improve the construction efficiency.
[0042] refer to Figure 1 and Figure 2 The elastic component 7 includes an inner rod 71, an outer tube 72, and a spring 73. One end of the outer tube 72 is fixedly connected to the outer wall of the left ring plate 4 or the outer wall of the right ring plate 5, and the other end is suspended in a direction away from the conduit 2. One end of the inner rod 71 is inserted into the outer tube 72, and the other end is rotatably connected to the first ball 21, the second ball 22, or the third ball 23, that is, the first ball 21, the second ball 22, or the third ball 23 rotates relative to its corresponding inner rod 71. The spring 73 is located inside the outer tube 72, and one end of the spring 73 is fixedly connected to the inner wall of the outer tube 72, and the other end is fixedly connected to the end of the inner rod 71.
[0043] refer to Figure 2 and Figure 3 The third ball bearing 23 is located at the end of the left ring plate 4 away from the hinged end with the right ring plate 5. The outer tube 72 of the third ball bearing 23 is fixed on the left ring plate 4, and the outer wall of the outer tube 72 of the third ball bearing 23 is threaded. A locking component 8 is provided at the third ball bearing 23. The locking component 8 includes a rotating nut 81 and a limiting rod 82. The rotating nut 81 is sleeved on the outer wall of the outer tube 72 where the third ball bearing 23 is located, and the rotating nut 81 is threadedly connected to the outer tube 72. The limiting rod 82 is rotatably connected to the outer wall of the rotating nut 81, that is, the rotating nut 81 rotates relative to the limiting rod 82. A bearing can be added to the outer wall of the rotating nut 81 to realize the rotatable connection between the rotating nut 81 and the limiting rod 82. This is not shown in the figure. The right ring plate 5 has an insertion hole 51 located near the third ball bearing 23. After the left ring plate 4 and the right ring plate 5 are fitted onto the outer wall of the tube 2, the end of the limiting rod 82 is inserted into the insertion hole 51 by rotating the rotating nut 81, thus completing the closure of the left ring plate 4 and the right ring plate 5.
[0044] refer to Figure 3 and Figure 4A secondary plate 52 is hinged to the right ring plate 5, with the hinge axis set horizontally. When the right ring plate 5 is vertical, the hinge axis between the right ring plate 5 and the secondary plate 52 is located at the bottom of the right ring plate 5. The end of the outer tube 72 at the second ball 22 is tapered, and the outer wall of the outer tube 72 at the second ball 22 is threaded. The outer tube 72 of the second ball 22 passes through the secondary plate 52 and is threadedly connected to the right ring plate 5.
[0045] refer to Figure 3 and Figure 4 When two conduits 2 need to be inserted at the same time, rotate the sub-plate 52 to open the sub-plate 52. A wire take-up groove 53 is provided on the inner wall of the sub-plate 52. The wire take-up groove 53 is opened horizontally along the arc-shaped inner wall of the sub-plate 52. The wire take-up groove 53 contains a steel wire 6. When the insertion hole 51 is opened, the sub-plate 52 is passed through at the same time. One end of the steel wire 6 is fixedly connected to the groove wall of the wire take-up groove 53 away from the insertion hole 51. That is, the steel wire 6 is wrapped around the outer wall of the conduit 2 and then passes through the insertion hole 51 on the sub-plate 52 to form a binding and fixation.
[0046] refer to Figure 4 To facilitate the fixing of the outer tube 72 at the second ball bearing 22, a through hole 9 is provided on the outer tube 72 at the second ball bearing 22. The steel wire 6 passes through the through hole 9 while surrounding the outer wall of the tube 2. At this time, the conical end of the outer tube 72 at the second ball bearing 22 is inserted into the sub-plate 52. Due to the presence of the conical shape, even if the position of the second ball bearing 22 needs to be adjusted at any time, the outer tube 72 at the second ball bearing 22 can be easily inserted and fixed to the sub-plate 52.
[0047] refer to Figure 5 and Figure 6 In the vertical direction, during wall construction, a grout-blocking pipe 3 is placed between adjacent blocks with openings. The outer diameter of the grout-blocking pipe 3 is equal to the inner diameter of the block opening. A ring 31 is fixed on the outer wall of the grout-blocking pipe 3. The distance between the ring 31 and the end of the grout-blocking pipe 3 is not less than the thickness of the mortar spread during block construction, and the thickness of the ring 31 is less than the thickness of the mortar spread during block construction. In the vertical state, the top end face of the grout-blocking pipe 3 is chamfered, that is, the top end face of the grout-blocking pipe 3 is centrally recessed.
[0048] A method for concealed conduit installation in walls includes: S1. Determining the opening position on the masonry block where the conduit 2 will be installed, and making the corresponding opening in the block; the opening can be prefabricated in the factory, and can be achieved using a block hole opener or other equipment. S2. Constructing the masonry wall, and placing the opened blocks in the corresponding positions to form the conduit embedment space 1; when constructing vertically, placing grout-blocking pipes 3 between the opened blocks and spreading mortar to ensure the fixation effect between adjacent blocks and between the grout-blocking pipes 3 and the blocks. S3. Fixing a left ring plate 4 and a right ring plate 5 on the outer wall of the conduit 2, and before the masonry wall is capped, inserting the conduit 2 into the reserved conduit embedment space 1 and connecting it to the junction box in the junction box groove; the junction box is fixed squarely and securely with masonry mortar. When it is necessary to simultaneously insert two conduits 2 within the pre-embedded space 1, open the auxiliary plate 52, wrap the steel wire 6 around the second conduit 2, and fix the second ball bearing 22. This completes the connection and positioning of the two conduits 2, achieving the effect of inserting two conduits 2 simultaneously. Ultimately, this avoids damaging the wall surface later, reducing pollution to the construction environment, and also avoids the quality problem of easy cracking of the wall surface at the grooved area after groove repair, ensuring the aesthetics of the wall.
