Description

Technical Field

[0001] This utility model relates to the field of fixing drainage pipes through plates, and in particular to a structure for fixing water supply and drainage pipes through plates. Background Technology

[0002] Water supply and drainage refers to the pipeline system consisting of horizontal main pipes, risers and branch pipes, and the drainage system. In industrial and civil buildings, water supply and drainage systems are a very important part. When carrying out water supply and drainage work, water supply and drainage pipes are needed to assist in completing the work. The main pipes of water supply and drainage are generally set in a vertical direction and sometimes need to pass through the floor slab.

[0003] In the construction of building water supply and drainage systems, in order to lay pipes, it is necessary to drill through holes in the floor slab with a diameter larger than the outer diameter of the water supply and drainage pipes. Currently, it is common to use expanded foam to fill the gap between the through holes and the pipes to fix the water supply and drainage pipes. However, this traditional fixing method has obvious technical defects:

[0004] Insufficient support strength: Expanded foam itself has low physical strength and is difficult to provide reliable support for water supply and drainage pipes, especially in the installation of pipes with large diameters or in high-rise buildings, where it is prone to sagging and deformation due to the weight of the pipes themselves.

[0005] Poor impact resistance: Water flow impact during water supply and drainage operations will cause pipe vibration, while the buffering and fixing capacity of expanded foam is limited. Long-term vibration can easily loosen the connection between the pipe and the through hole, leading to fixing failure.

[0006] Damaged pipe lifespan: Unsecured water supply and drainage pipes will continue to sway under the impact of water flow, which will aggravate wear and stress concentration at the pipe joints, directly shorten the service life of the pipes and increase the later maintenance costs.

[0007] Therefore, it is necessary to provide a pipe penetration and fixing structure to solve the above-mentioned technical problems. Utility Model Content

[0008] This utility model provides a pipe penetration and fixing structure for water supply and drainage pipes, which solves the problems of low strength of expanded foam when using expanded foam to fix the pipes between the pipe penetration holes and the pipes in the floor slab during the construction of building water supply and drainage systems. These problems include: poor impact resistance, water flow impact causing pipe vibration, loosening of the connection between the pipe and the penetration hole, failure of the fixation; unstable pipe fixation, shaking under water flow impact, aggravating joint wear and stress concentration, shortening life and increasing maintenance costs; and the expanded foam filling being greatly affected by the environment, with unstable curing performance, making it impossible to accurately position the pipes and making the construction quality uncontrollable.

[0009] To solve the above-mentioned technical problems, this utility model provides a pipe through-plate fixing structure for water supply and drainage, comprising:

[0010] Two mounting rings, two adjusting components, multiple extrusion components, and two fixing components;

[0011] The two adjustment components are respectively disposed on the inner walls of the two mounting rings. Each adjustment component includes a plurality of first telescopic members and an arc-shaped adjustment plate. The plurality of first telescopic members are respectively connected to the inner walls of the mounting rings, and the arc-shaped adjustment plate is connected between the plurality of first telescopic members.

[0012] The plurality of the extrusion components are respectively disposed on one side of the two arc-shaped adjustment plates;

[0013] The two fixing components are disposed between the two mounting rings.

[0014] Preferably, the extrusion assembly includes a second telescopic member, a U-shaped mounting bracket, and an extrusion roller. The second telescopic member is connected to the interior of the arc-shaped adjusting plate, and the U-shaped mounting bracket is connected to one end of the second telescopic member.

[0015] Preferably, the extrusion roller is rotatably connected to the interior of the U-shaped mounting frame via a rotating shaft.

[0016] Preferably, the fixing component includes a threaded bolt and a threaded sleeve, the threaded bolt being disposed between the two mounting rings, and the threaded sleeve being threadedly connected to the surface of the threaded bolt.

[0017] Preferably, a disassembly assembly is provided between the mounting ring and the plurality of first telescopic members. The disassembly assembly includes a disassembly groove, a disassembly block, and a connecting bolt. The disassembly groove is formed in the inner wall of the mounting ring, and the disassembly block is plugged into the interior of the disassembly groove and connected to one end of the first telescopic member.

[0018] Preferably, the connecting bolt is disposed between the mounting ring and the disassembly block.

[0019] Preferably, the disassembly groove and the disassembly block are used for disassembly between the first telescopic member and the mounting ring.

[0020] Compared with related technologies, the water supply and drainage pipe through-plate fixing structure provided by this utility model has the following beneficial effects:

[0021] This utility model provides a pipe through-plate fixing structure for water supply and drainage, which significantly improves the support strength and prevents pipe sagging: it adopts a rigid structure design with two installation rings and adjustment components, and multiple first telescopic components and arc-shaped adjustment plates form a ring-shaped support, which can withstand the self-weight of large-diameter water supply and drainage pipes. In the pipe layout of high-rise buildings, it can effectively prevent the sagging deformation of pipes caused by their own weight and ensure the verticality of pipe installation.

[0022] Excellent impact resistance and reliable fixation: The extrusion roller in the extrusion assembly is rotatably connected to the U-shaped mounting bracket through a rotating shaft. When water flow impact causes pipe vibration, the extrusion roller can roll along the pipe axis, converting vibration energy into rolling friction force, which reduces the amplitude of pipe vibration.

[0023] The second telescopic component provides adjustable radial compressive force, which, together with the uniform pressure distribution of the arc-shaped adjustment plate, significantly improves the impact resistance of the fixed structure and prevents the connection between the pipe and the through hole from loosening due to long-term vibration.

[0024] Precise positioning and adjustment ensure controllable construction quality: The adjustment component achieves precise positioning of pipes of different diameters through the synchronous expansion and contraction of multiple first expansion components, avoiding the problem of unstable curing performance caused by the influence of ambient temperature and humidity in the traditional expansion foam filling process, resulting in good consistency of construction quality.

[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0033] First Embodiment

[0034] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A schematic diagram of the first embodiment of a pipe through-plate fixing structure provided by this utility model; Figure 2 for Figure 1 The enlarged schematic diagram of part A shown below; Figure 3 for Figure 1 The enlarged schematic diagram of section B is shown below; Figure 4 for Figure 1 The diagram shows a three-dimensional structural schematic of the fixing structure. A water supply and drainage pipe through-plate fixing structure includes:

[0035] Two mounting rings 1, two adjusting components 2, multiple pressing components 3, and two fixing components 4;

[0036] The two adjustment components 2 are respectively disposed on the inner walls of the two mounting rings 1. The adjustment component 2 includes a plurality of first telescopic members 21 and an arc-shaped adjustment plate 22. The plurality of first telescopic members 21 are respectively connected to the inner walls of the mounting rings 1, and the arc-shaped adjustment plate 22 is connected between the plurality of first telescopic members 21.

[0037] The plurality of extrusion components 3 are respectively disposed on one side of the two arc-shaped adjustment plates 22;

[0038] The two fixing components 4 are disposed between the two mounting rings 1.

[0039] The extrusion assembly 3 includes a second telescopic member 31, a U-shaped mounting bracket 32, and an extrusion roller 33. The second telescopic member 31 is connected to the interior of the arc-shaped adjusting plate 22, and the U-shaped mounting bracket 32 ​​is connected to one end of the second telescopic member 31.

[0040] The extrusion roller 33 is rotatably connected to the interior of the U-shaped mounting bracket 32 ​​via a rotating shaft.

[0041] The fixing component 4 includes a threaded bolt 41 and a threaded sleeve 42. The threaded bolt 41 is disposed between the two mounting rings 1, and the threaded sleeve 42 is threadedly connected to the surface of the threaded bolt 41.

[0042] Multiple first telescopic components 21 (preferably hydraulic or pneumatic telescopic cylinders) are evenly distributed on the inner wall of the mounting ring 1. Through synchronous telescopic action, they push the arc-shaped adjusting plate 22 to move radially. When the pipe is inserted into the through hole, the first telescopic components 21 automatically adjust the extension length according to the outer diameter of the pipe, so that the arc-shaped adjusting plate 22 is tightly attached to the outer wall of the pipe.

[0043] Uniform pressure distribution: The arc-shaped regulating plate 22 adopts an arc-shaped design that matches the outer wall of the pipe, ensuring that the thrust of multiple first expansion joints 21 is evenly transmitted to the pipe surface, avoiding local stress concentration. The expansion and contraction of the first expansion joint 21 is controlled by the feedback of the pressure sensor to ensure that the thrust of each expansion joint is consistent.

[0044] Adjustment precision control: The first expansion joint 21 uses a high-precision displacement sensor to monitor the expansion and contraction in real time, and realizes precise adjustment of pipes with different diameters through a closed-loop control system.

[0045] The second telescopic component 31 (using an elastic telescopic rod or a small hydraulic rod) is installed inside the arc-shaped adjusting plate 22. Through its telescopic movement, it pushes the U-shaped mounting bracket 32 ​​to move radially, causing the extrusion roller 33 to fit tightly against the outer wall of the pipe. The telescopic range of the second telescopic component 31 can be adjusted according to the pipe fixing requirements.

[0046] Dynamic buffering mechanism: The squeezing roller 33 is rotatably connected to the U-shaped mounting bracket 32 ​​via a rotating shaft. When the pipeline vibrates due to water flow impact, the squeezing roller 33 can roll along the pipeline axis, converting some of the vibration energy into rolling friction, thereby reducing the vibration amplitude of the pipeline.

[0047] Wear-resistant design: The surface of the extrusion roller 33 is made of high-hardness wear-resistant rubber material and has anti-slip texture, which can increase the friction between the roller and the pipe and avoid damage to the pipe surface caused by hard contact.

[0048] Two mounting rings 1 are placed on the upper and lower sides of the floor slab respectively. The threaded bolt 41 passes through the pipe hole in the floor slab and the through hole on the mounting ring 1. It is tightened and fixed by the threaded sleeve 42, which rigidly connects the entire fixing structure to the floor slab. The threaded bolt 41 is made of high-strength carbon steel to ensure the load-bearing capacity of the fixing structure.

[0049] Preload control: The tightening torque of the threaded sleeve 42 is controlled by a torque wrench to ensure that the mounting ring 1 fits tightly against the floor surface, avoiding relative displacement between the fixed structure and the floor. Reasonable control of the preload can effectively improve the vibration resistance of the entire fixed structure.

[0050] Ease of installation: The threaded bolt 41 and threaded sleeve 42 use standard metric threads, which facilitates on-site installation and disassembly, improving construction efficiency.

[0051] Pipe installation and positioning: Pass the water supply and drainage pipes through the pipe holes in the floor slab and initially position them to the design location.

[0052] Adaptive adjustment of components: The automatic adjustment mode of the first expansion joint 21 is activated. The system automatically adjusts the extension length of each first expansion joint 21 according to the pressure feedback from the outer wall of the pipeline, so that the arc-shaped adjustment plate 22 fits the pipeline evenly.

[0053] The extrusion assembly applies a fixing force: the second telescopic member 31 extends and pushes the extrusion roller 33 to fit tightly against the outer wall of the pipe. The pressure sensor monitors and adjusts the extrusion force to the set value.

[0054] Fixed component connection and fixing: Pass the threaded bolt 41 through the mounting ring 1 and the floor slab, and tighten it with the threaded sleeve 42 to complete the connection between the fixed structure and the floor slab.

[0055] Dynamic monitoring and compensation: The system monitors the vibration amplitude of the pipeline and the preload of the fixing components in real time. When the vibration amplitude exceeds the threshold, it automatically adjusts the expansion and contraction of the second expansion member 31 to enhance the squeezing and fixing force and achieve dynamic compensation.

[0056] Compared with related technologies, the water supply and drainage pipe through-plate fixing structure provided by this utility model has the following beneficial effects:

[0057] This utility model provides a pipe through-plate fixing structure for water supply and drainage, which significantly improves the support strength and prevents pipe sagging: It adopts a rigid structure design with two installation rings 1 and adjustment components 2, and multiple first telescopic parts 21 and arc-shaped adjustment plate 22 form a ring-shaped support, which can withstand the self-weight of large-diameter water supply and drainage pipes. In the pipe layout of high-rise buildings, it can effectively prevent the sagging deformation of pipes caused by their own weight and ensure the verticality of pipe installation.

[0058] Excellent impact resistance and reliable fixation: The extrusion roller 33 in the extrusion assembly 3 is rotatably connected to the U-shaped mounting bracket 32 ​​through a rotating shaft. When the water flow impact causes the pipe to vibrate, the extrusion roller 33 can roll along the pipe axis, converting the vibration energy into rolling friction force, which reduces the vibration amplitude of the pipe.

[0059] The second telescopic component 31 provides adjustable radial extrusion force, which, together with the uniform pressure distribution of the arc-shaped adjustment plate 22, significantly improves the impact resistance of the fixed structure and avoids loosening of the connection between the pipe and the through hole due to long-term vibration.

[0060] Precise positioning and adjustment ensure controllable construction quality: The adjustment component 2 achieves precise positioning of pipes of different diameters through the synchronous expansion and contraction adjustment of multiple first expansion parts 21, avoiding the problem of unstable curing performance caused by the influence of ambient temperature and humidity in the traditional expansion foam filling process, resulting in good consistency of construction quality.

[0063] Specifically, the difference in the second embodiment of this application regarding the through-plate fixing structure for water supply and drainage pipes is that a disassembly assembly 5 is provided between the mounting ring 1 and the plurality of first telescopic members 21 in the through-plate fixing structure for water supply and drainage pipes.

When it is necessary to disassemble the first telescopic member 21, simply unscrew the connecting bolt 53 to pull the disassembly block 52 out of the disassembly groove 51, thereby achieving quick disassembly of the first telescopic member 21.

[0067] Positioning and Fixing: The mating surfaces of the disassembly block 52 and the disassembly groove 51 are designed with a trapezoidal structure to ensure accurate positioning during installation. The connecting bolt 53 uses a countersunk screw, which, after tightening, has a head flush with the inner wall of the mounting ring 1, without affecting the movement of the arc-shaped adjusting plate 22.

[0068] Ease of maintenance: The design of disassembling component 5 greatly improves maintenance efficiency and reduces maintenance costs by making it easier to replace the individual first telescopic component 21.

[0075] Material selection: All parts of disassembly component 5 are made of stainless steel (such as 304 stainless steel), which has good corrosion resistance and is suitable for humid water supply and drainage environments.

[0076] Universal design: The dimensions of the disassembly slot 51 and the disassembly block 52 are designed to conform to the standard interface, which can be adapted to the first telescopic part 21 of different specifications, thus improving the versatility of the components.

It is not necessary to disassemble the entire fixed structure. Only the damaged first telescopic component 21 needs to be replaced, which greatly reduces equipment downtime and improves the operational reliability of the water supply and drainage system.

[0080] Facilitates equipment maintenance and upgrades: When pipeline maintenance or system upgrades are required, the first expansion joint 21 can be quickly disassembled by disassembly component 5 without affecting the normal operation of other components, improving construction flexibility, facilitating cleaning and inspection of the interior of the fixed structure, preventing minor faults from escalating, and extending the service life of the entire fixed structure.
