Description

Technical Field

[0001] This invention relates to the field of water pipe laying technology, specifically to a fixing device and a water pipe laying method for laying water pipes on the walls of construction sites. Background Technology

[0002] Water pipe installation in building walls is the construction process of installing a water pipe system inside or on the surface of a building wall. It includes locating the water pipe route according to the design drawings, cutting grooves in the wall to accommodate the pipes, fixing the pipes with pipe clamps or brackets, and connecting fittings to ensure sealing, so as to ensure water supply safety, structural integrity and interior aesthetics.

[0003] During the construction of embedded water pipes in walls, it is necessary to first chisel a groove in the wall and place the water pipe into the groove, and then connect the pipe ends. To prevent the water pipe from shifting during the connection work, metal pipe clamps are usually used in conjunction with steel nails for fixing. After pressing the pipe clamps over the water pipe, the steel nails are hammered to anchor it into the wall. This fixing method has the problems of difficult operation and non-reusability. Each section of water pipe requires an independent pipe clamp for positioning, which increases construction costs and wastes resources, resulting in low construction efficiency and a large amount of metal consumables wasted, which is not conducive to use. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a fixing device for laying water pipes on construction site walls. By combining a pipe arrangement and positioning mechanism with a position locking mechanism, it solves the problems in the prior art where pipe clamps are required for fixing the laid water pipes, resulting in cumbersome and inefficient fixing operations and resource waste due to the inability to reuse the clamps.

[0005] According to one embodiment of the present invention, a fixing device for laying water pipes on a construction site wall is provided, comprising a housing and a pipe arrangement positioning mechanism and a position locking mechanism thereon; the pipe arrangement positioning mechanism includes: a guide rail fixed on the housing; a plurality of sliders slidably disposed on the guide rail; a plurality of pipe clamps fixed on the sliders; a limiting component disposed on the housing for limiting the position of the sliders; the position locking mechanism includes: a control frame fixed in the housing; a bidirectional screw rotatably disposed on the control frame, with oppositely oriented external threads at both ends, one end extending outside the control frame; two threaded sleeves threadedly connected to the two ends of the bidirectional screw respectively; a sliding rod fixed on the outside of the guide rail; two mounting brackets slidably on the sliding rod and fixedly connected to the threaded sleeves, with a pressing block fixedly connected to opposite sides of the two mounting brackets.

[0006] As one embodiment, the limiting component includes: a bolt threaded through the housing; a movable plate slidably disposed in the housing, with a wedge fixed at one end and a friction strip inserted into the guide rail and opposite to the slider at the other end, the inclined surface of the wedge being opposite to the inner end of the bolt; and a spring, one end connected to the housing and the other end connected to the movable plate.

[0007] As one embodiment, a positioning sleeve fitted onto the bolt is also fixed inside the housing.

[0008] In one embodiment, the inner end of the bolt is fixed with a push block whose end face is arc-shaped, and the end face of the push block abuts against the inclined surface of the inclined block.

[0009] In one embodiment, the length direction of the bolt is perpendicular to the sliding direction of the movable plate.

[0010] As one embodiment, a slide rail is formed inside the housing for the movable plate to slide.

[0011] As one embodiment, a knob is fixedly provided at the outer end of the bolt.

[0012] As one embodiment, a limiting plate is fixedly provided at one end of the bidirectional screw extending outside the control frame; and a retainer is fixedly provided on both sides of the limiting plate on the control frame.

[0013] As one embodiment, the side of the extrusion block away from the mounting bracket is formed with several anti-slip textures.

[0014] According to one embodiment of the present invention, a method for laying water pipes in the walls of a construction site is provided, which adopts the above-mentioned fixing device for laying water pipes in the walls of a construction site, and includes the following steps: S1. Based on the number of water pipes to be laid, insert the corresponding number of sliders into the inner cavity of the guide rail, slide the sliders along the guide rail, and initially adjust the spacing of the pipe clamps to be the same as the spacing of each water pipe. S2. Place the fixing device on the front side of the wall groove, align the pipe clamp with the water pipe, and rotate the double screw to make the extrusion block fit tightly against the inner wall of the groove. S3. Move the water pipe to drive the slider to slide in the guide rail, adjust the arrangement of each water pipe, and make the water pipe spacing meet the design requirements. S4. Rotate the bolt to make its inner end press against the inclined surface of the inclined block, drive the movable plate forward, make the friction strip close to the slider, and use friction to lock the slider position. S5. Connect both ends of the water pipe. After the connection is completed, rotate the bidirectional screw in the opposite direction to disengage the extrusion block from the inner wall of the groove, loosen the bolts to reset the friction strip, and remove the fixing device from the water pipe.

[0015] As can be seen from the above description and practice, the fixing device for laying water pipes on construction site walls of the present invention, through the pipe arrangement and positioning mechanism, utilizes the sliding cooperation structure of guide rail and slider to realize the flexible adjustment of pipe clamp position, so that a single device can adapt to the water pipe arrangement requirements of different spacing, solve the problem of resource waste caused by the consumption of independent pipe clamps for each section of water pipe in traditional construction, reduce the amount of metal consumables used, and improve the device reuse rate.

[0016] In addition, the position locking mechanism of the present invention uses a bidirectional screw to synchronously drive the threaded sleeves and the extrusion block on both sides to move towards each other, so that the anti-slip texture on the surface of the extrusion block forms an adaptive pressing and fixing with the inner wall of the wall groove. The housing can be quickly positioned without steel nail anchoring, solving the problem of difficult operation and non-reusability of water pipe laying and arrangement, simplifying the installation steps and reducing construction time.

Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] like Figures 1 to 5 As shown, in this embodiment, a fixing device for laying water pipes on a construction site wall is disclosed, including a housing 1 and a pipe arrangement positioning mechanism 2 and a position locking mechanism 3 on it. The pipe arrangement positioning mechanism 2 is fixedly connected to the front side of the housing 1, and the position locking mechanism 3 is fixedly connected to the bottom of the front side of the housing 1.

[0026] The pipe arrangement and positioning mechanism 2 includes a guide rail 21, several sliders 22, several pipe clamps 23, and a limiting component 24. The rear side of the guide rail 21 is fixedly connected to the housing 1, the inner cavity of the guide rail 21 is slidably connected to the sliders 22, the front side of the sliders 22 is fixedly connected to the pipe clamps 23, and the inner cavity of the housing 1 is provided with a limiting component 24 to limit the position of the sliders 22.

[0027] The position locking mechanism 3 includes a control frame 31, a bidirectional screw 32, two threaded sleeves 33, a slide rod 39, and two mounting brackets 34. The rear side of the control frame 31 is fixedly connected to the housing 1. The bidirectional screw 32 is rotatably connected inside the control frame 31. The two ends of the bidirectional screw 32 have external threads in opposite directions, with one end extending outside the control frame 31. The two threaded sleeves 33 are threadedly connected to the two ends of the bidirectional screw 32, respectively. Both ends of the slide rod 39 are fixed to the outside of the guide rail 21. The two mounting brackets 34 are slidably connected to the slide rod 39 via sliding sleeves 38. A pressing block 35 is fixedly connected to opposite sides of each of the two mounting brackets 34.

[0028] The guide rail 21 facilitates the sliding of the slider 22 within it. The slider 22 can fix the pipe clamp 23, and the position of the pipe clamp 23 can be adjusted while the slider 22 moves. The limiting component 24 can limit the slider 22 to prevent displacement. The pipe clamp 23 can fix the water pipe. Multiple pipe clamps 23 can be used to arrange and fix multiple water pipes to prevent displacement during the docking process. The control frame 31 facilitates the installation of the bidirectional screw 32. The bidirectional screw 32 can cooperate with the threaded sleeve 33 to control the position of the mounting bracket 34 and the pressing block 35. The pressing block 35 moves inside the water pipe installation groove in the wall. The two pressing blocks 35 press against the inner wall of the groove, so that the housing 1 can be stably fixed on the front side of the groove, while preventing the water pipe from shifting or tilting.

[0029] Furthermore, in this embodiment, to improve the stability of the bidirectional screw 32, a limiting plate 37 is fixedly provided at one end of the bidirectional screw 32 extending outside the control frame 31, and retainers 36 located on both sides of the limiting plate 37 are fixedly provided on the outside of the control frame 31. The retainers 36 clamp the limiting plate 37 to prevent the bidirectional screw 32 from rotating in the opposite direction during use. The retainer 36 is prior art, and its cooperation with the limiting plate 37 is similar to that of the brake and brake disc on a car or bicycle, so the specific structure will not be described in detail.

[0030] In this embodiment, the limiting component 24 includes a bolt 241, a movable plate 244, and a spring 245. The bolt 241 is threaded onto the housing 1, and a threaded hole for the bolt 241 is provided at the top of the housing 1. A knob is fixedly connected to the top of the bolt 241 for easy rotation by the user. The movable plate 244 is slidably disposed within the housing 1. A wedge 243 is fixedly provided at one end near the bolt 241, and a friction strip 246 is fixedly provided at the other end near the guide rail 21. One end of the friction strip 246 passes into the guide rail 21 and is positioned opposite to the slider 22. The inclined surface of the wedge 243 is opposite to the inner end of the bolt 241. One end of the spring 245 is connected to the housing 1, and the other end is connected to the movable plate 244.

[0031] A positioning sleeve 247 is also fixedly installed inside the housing 1, which fits onto the bolt 241 and ensures that the bolt 241 will not wobble during use. A push block 242 with an arc-shaped end face is fixedly installed at the inner end of the bolt 241, and the end face of the push block 242 abuts against the inclined surface of the inclined block 243. The bottom of the bolt 241 is movably connected to the push block 242 through a bearing, so that when the bolt 241 rotates, the push block 242 can push the inclined block 243 to move.

[0032] Furthermore, the length direction of the bolt 241 is perpendicular to the sliding direction of the movable plate 244, which can improve the operational stability of the fixing device. Furthermore, in this embodiment, a slide rail 248 is formed inside the housing 1 for the movable plate 244 to slide along, further improving the operational stability of the fixing device.

[0033] In this embodiment, the side of the compression block 35 away from the mounting bracket 34 has several anti-slip textures. A triangular reinforcing block is fixedly connected between the bottom of the mounting bracket 34 and the compression block 35, which can improve the stability of the fixing device during use. Handles 4 are fixedly connected to both ends of the rear side of the housing 1, and a limit opening is opened on the front side of the housing 1 to facilitate user operation of the fixing device.

[0034] The bolt 241 controls the height of the push block 242, which, during movement, presses against the inclined surface of the inclined block 243, controlling the movement of the movable plate 244 and the friction strip 246. The friction strip 246 presses against the slider 22, using friction to prevent displacement. The spring 245 resets the movable plate 244 and the friction strip 246 when the inclined block 243 is no longer pressed. The positioning sleeve 247, in conjunction with the housing 1, limits the bolt 241, allowing it to move smoothly up and down and preventing tilting during movement. The bearing facilitates the pressing of the push block 242 against the inclined surface of the inclined block 243 during downward pressure. The knob allows the user to easily rotate the bolt 241. The slide rod 39 and the slide sleeve 38 limit the mounting bracket 34, allowing it to move stably left and right and preventing rotation during movement. The anti-slip texture improves the stability of the pressing block 35 when fixing the housing 1. The opposite threads allow the bidirectional screw 32 to simultaneously control the threaded sleeve 33 to move to opposite or opposite sides. The triangular reinforcing block improves the stability of the connection between the mounting bracket 34 and the pressing block 35. The handle 4 makes it easy for the user to lift the housing 1 to its installation position, and the limiting opening facilitates the friction strip 246 to enter or exit the inner cavity of the guide rail 21.

[0035] The working principle of this invention is as follows: A corresponding number of sliders 22 are inserted into the guide rail 21 according to the number of water pipes. Then, the user places the pipe clamps 23 into the wall groove using the handle 4, thus fixing the water pipes. By rotating the portion of the bidirectional screw 32 extending to the outside of the housing 1, the bidirectional screw 32 controls the movement of the two threaded sleeves 33 and the mounting bracket 34. The movement of the mounting bracket 34 controls the two pressing blocks 35 to press against both sides of the inner wall of the groove. The two pressing blocks 35 fit tightly against the inner wall of the groove, thereby stably and quickly fixing the housing 1. Subsequently, the user adjusts the position of each water pipe, and the water pipes will... The slider 22 moves together. After the water pipe position is adjusted, the bolt 241 is rotated. The bolt 241 controls the push block 242 to press down on the inclined surface of the inclined block 243. After the inclined block 243 is pressed, the movable plate 244 is controlled to stretch the spring 245. At the same time, the movable plate 244 controls the friction strip 246 to press the slider 22, using friction to prevent the slider 22 from moving. Then the user can connect the two ends of the water pipe. The water pipe will not tilt or shift inside the groove. After the water pipe is connected, the bidirectional screw 32 can be rotated in the opposite direction to make the pressing block 35 disengage from the inner wall of the groove. The housing 1 can then be taken out for reuse, improving the component reuse rate.

[0036] The present invention also provides a method for laying water pipes in the walls of construction sites, which uses the above-mentioned fixing device for laying water pipes in the walls of construction sites, and includes the following steps: S1. Based on the number of water pipes to be laid, insert the corresponding number of sliders 22 into the inner cavity of the guide rail 21, slide the sliders 22 along the guide rail 21, and initially adjust the spacing of the pipe clamps 23 to be the same as the spacing of each water pipe, so that the pipe clamps 23 match the water pipe layout requirements.

[0037] S2. Hold the handle 4 on the back of the housing 1 and place the fixing device in front of the wall groove, align the pipe clamp 23 with the water pipe, and rotate the double-acting screw 32. Since the threads on both sides of the double-acting screw 32 are opposite, it drives the threaded sleeves 33 on both sides and the mounting bracket 34 to move towards each other, so that the extrusion block 35 is tightly attached to the inner wall of the groove.

[0038] S3. Moving the water pipe causes the slider 22 to slide within the guide rail 21, adjusting the arrangement of each water pipe so that the spacing between the water pipes meets the design requirements.

[0039] S4. Rotate the bolt 241 so that its inner end presses against the inclined surface of the inclined block 243, which drives the movable plate 244 to push forward, so that the friction strip 246 is in close contact with the slider 22, and uses friction to lock the position of the slider 22 to prevent the water pipe from shifting.

[0040] S5. After confirming that the pipe clamp 23 is fixed and stable, connect the two ends of the water pipe. At this time, the housing 1 and the pipe clamp 23 can prevent the water pipe from shaking or shifting during construction. After the connection is completed, rotate the bidirectional screw 32 in the opposite direction to make the squeezing block 35 disengage from the inner wall of the groove, loosen the bolt 241 to reset the friction strip 246, and use the handle 4 to remove the fixing device from the water pipe. After cleaning, it can be reused in other construction scenarios to improve the utilization rate.

[0041] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
