Description

Technical Field

[0001] This application relates to the field of water supply and drainage pipeline technology, and in particular to a seismic-resistant structure for building water supply and drainage pipelines. Background Technology

[0002] In the field of building engineering, seismic reinforcement of electromechanical engineering facilities has always been a crucial aspect, and its importance has become increasingly prominent with the continuous development of the construction industry. With the acceleration of urbanization, various types of buildings are springing up, and the electromechanical engineering facilities inside these buildings, such as water supply and drainage, fire protection, heating, ventilation, air conditioning, gas, heat, electricity, and communications, are becoming increasingly complex and diverse. Seismically reinforced electromechanical engineering facilities can play a significant role in the event of an earthquake of the local seismic fortification intensity. They can effectively reduce the degree of earthquake damage to buildings and reduce and prevent secondary disasters.

[0003] Under relevant technologies, various methods are conventionally used to achieve seismic resistance for building electromechanical engineering facilities. For pipeline facilities, traditional rigid supports are often used for support and fixation. These supports connect the pipeline to the building's load-bearing structure using bolts and other connectors to limit pipeline displacement. Welding is also used to firmly combine the supports with the pipeline and load-bearing structure, enhancing the stability of the connection. In addition, some projects add cushioning materials such as rubber pads between the supports and the pipeline to absorb some vibration energy. For larger electromechanical equipment, large steel frame structures are used for overall support, and the frame is fixed to the ground with anchor bolts to prevent the equipment from shaking significantly during an earthquake.

[0004] Regarding the aforementioned technologies, existing supports have significant drawbacks, failing to adapt to the number of pipes when designing support structures. In actual building electromechanical engineering, the number and layout of pipes vary, and existing supports cannot flexibly adapt to the support requirements of different numbers of pipes. This results in poor support performance in some cases, making it difficult to effectively limit pipe displacement and control vibration. Consequently, they cannot adequately protect electromechanical engineering facilities during earthquakes, increasing the risk of secondary disasters. Summary of the Invention

[0005] In order to enable the setting of support structures according to the number of pipes, this application provides a seismic-resistant structure for building water supply and drainage pipes.

[0006] This application provides a seismic-resistant structure for building water supply and drainage pipelines, employing the following technical solution: A seismic-resistant structure for building water supply and drainage pipes, including A support frame, the support frame including a support rod and an extension rod, the support rod being parallel to the extension rod and both being parallel to a first direction, the extension rod being slidably connected to the support rod along the first direction; A fixing component is provided with multiple fixing components spaced apart along a first direction. The fixing components are detachably installed on the support rod and the extension rod. The fixing components include two fixing half-rings and a clamping plate. The two fixing half-rings are detachably connected and symmetrically arranged. A fixing area is formed between the two fixing half-rings. The clamping plate is spaced apart in the fixing area along a second direction, which is perpendicular to the first direction. An anti-seismic component is provided correspondingly to the clamping plate. The anti-seismic component includes an elastic element and a buffer plate. The buffer plate is disposed between the clamping plate and the fixed half-ring. The extension and retraction direction of the elastic element is parallel to a second direction. The elastic element is fixedly connected between the clamping plate and the buffer plate. The buffer plate is slidably connected to the fixed half-ring along the second direction.

[0007] By adopting the above technical solution, by setting up support frames, fixing components and anti-seismic components, and installing a corresponding number of fixing components according to the number of pipes, and by sliding an extension rod along the first direction according to the installation position of the pipe, fixing components corresponding to the pipe position can be installed on the extension rod to clamp the pipe between two clamping plates. The two clamping plates are then slid along the second direction according to the diameter of the pipe, and the pipe is clamped and fixed by the two clamping plates. By setting up elastic elements, the external forces received by the pipe are buffered, thereby reducing the impact force transmitted to the pipe and improving the stability of the pipe.

One end of the first screw passes through the side wall of the fixed half ring and is fixedly connected to the buffer plate, while the other end is located on the side of the fixed half ring away from the buffer plate. It also includes a guide rod for guiding the sliding of the buffer plate along the second direction. By adopting the above technical solution, by setting a first screw, rotating the first screw causes the buffer plate to slide in the second direction, which in turn causes the clamping plate to slide in the second direction.

[0009] Optionally, the guide rod is parallel to the second direction, one end of the guide rod passes through the fixed semi-ring and is located in the fixed area, and the buffer plate is sleeved on the guide rod and slides along the length of the guide rod.

[0010] By adopting the above technical solution and setting a guide rod, the sliding of the buffer plate along the second direction is guided by the guide rod. Optionally, an arc-shaped groove is provided through one side of the two clamping plates that are close to each other along a third direction.

[0011] By adopting the above technical solution and setting an arc-shaped groove, the groove wall fits snugly against the outer wall of the pipe, thereby improving the clamping stability of the pipe.

[0012] Optionally, each of the fixed half-rings and the support frame is fixed together by an installation assembly. The installation assembly includes an upper locking nut, a lower locking nut, a sliding seat, and two second screws. The second screws are parallel to a second direction. Each fixed half-ring has a second screw on both sides. One end of each second screw is fixedly connected to the sliding seat. Each fixed half-ring has a mounting seat fixedly connected to both ends. The two mounting seats pass through and slide along the axis of the second screw. The threads of the two second screws have opposite directions. The upper locking nut and the lower locking nut are threaded to the second screw. The two mounting seats are clamped between the upper locking nut and the lower locking nut. The sliding seat is fixedly connected to the bottom wall of the second screw. The top wall of the support rod has a first groove along a first direction. The sliding seat slides in the first groove along the first direction.

[0013] By adopting the above technical solution and setting up installation components, the fixed half ring can slide on the screw, and the fixed half ring is fixed by the upper and lower locking nuts to adapt to pipelines with different installation heights.

[0014] Optionally, the top wall of the extension rod is provided with a second sliding groove along the first direction for the sliding seat to slide, and the second sliding groove and the first sliding groove are connected in the first direction.

[0015] By adopting the above technical solution and setting a second sliding groove, the sliding seat can also move on the second sliding groove of the extension rod, thereby adapting to different installation positions of the pipeline.

[0016] Optionally, one end of the extension rod is connected to a first slider, the first groove passes through the end wall of the support rod along a first direction, a limiting block is fixedly connected to the end wall of the support rod, the first slider is located in the first groove and slides along the groove wall of the first groove, the limiting block blocks the first slider from sliding out of the first groove, and the first slider passes through a fifth groove along the first direction for the sliding seat to slide.

[0017] By adopting the above technical solution, in order for the extension rod to slide, a first slider is set, which slides in the first groove, and the limiting block limits the first groove to prevent the limiting block from sliding out of the first groove.

[0018] Optionally, the limiting blocks are located on both sides of the support rod, the extension rod is rotatably connected to the first slider, the extension rod is parallel to a third direction along the rotation axis of the first slider, and there is space between the two limiting blocks for the extension rod to rotate.

[0019] By adopting the above technical solution, in certain construction environments, pipelines need to be laid inside the ceiling. In order to further improve the stability of the pipeline, an extension rod is set to be rotatably connected to the first slider. When the extension rod slides to the end of the support rod and abuts against the limiting block, the extension rod can be rotated to be perpendicular to the support rod, and one end of the extension rod is located above the support rod, fixing the extension rod to the ceiling wall to achieve support for the pipeline.

[0020] Optionally, the first slider is fixedly connected to two fixed seats on the side near the extension rod, the extension rod is rotatably connected between the two fixed seats, and the side wall of the fixed seat is in contact with the side wall of the limiting block.

[0021] By adopting the above technical solution, by setting a fixed seat, the extension rod is rotatably connected to the fixed seat, and the fixed seat can still slide in the first groove with the first slider.

[0022] Optionally, it also includes a telescopic rod, which is located between one of the fixed half-rings and the sliding seat. The movable section of the telescopic rod is fixedly connected to the fixed half-ring, and the fixed section of the telescopic rod is fixedly connected to the sliding seat. The ends of the fixed section and the movable section of the telescopic rod that are close to each other are slidably connected along a second direction.

[0023] By adopting the above technical solution, when there are multiple pipelines at the construction site, the height of the pipelines may vary. The height of the fixing component can be adjusted by sliding the mounting seat. When the height of the fixing half ring changes, a telescopic rod is installed to further support the fixing half ring, thereby improving stability.

[0026] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0027] This application discloses an earthquake-resistant structure for building water supply and drainage pipelines. For ease of description, this application introduces directional terms such as first direction, second direction, and third direction to form a three-dimensional reference direction. The directional terms used, such as "first direction, second direction, and third direction," can be specifically referred to in the figure, where the first direction is represented by X, the second direction by Y, and the third direction by Z. The first direction, the second direction, and the third direction are perpendicular to each other.

[0028] Reference Figure 1 and Figure 2The seismic-resistant structure of the building's water supply and drainage pipeline includes a support frame 1 and a fixing component 2. The support frame 1 includes a support rod 11 and an extension rod 12. The support rod 11 is parallel to the extension rod 12 and both are parallel to a first direction. The extension rod 12 is slidably connected to the support rod 11 along the first direction. Multiple fixing components 2 are spaced apart along the first direction. The fixing components 2 are detachably installed on the support rod 11 and the extension rod 12. The fixing components 2 include two fixing half-rings 21 and clamping plates 22. The two fixing half-rings 21 are detachably connected and symmetrically arranged. A fixing area 211 is formed between the two fixing half-rings 21. The clamping plates 22 are spaced apart within the fixing area 211 along a second direction, which is perpendicular to the first direction. The pipeline is clamped and fixed by the two clamping plates 22. By setting the extension rod 12, the extension rod 12 can be slid according to the actual number of pipelines to extend the length of the support rod 11, so as to install the same number of fixing components 2 as the number of pipelines, thereby achieving the clamping and fixing of the pipelines.

[0029] Reference Figure 2 To mitigate vibration in the pipeline, the seismic structure of the building's water supply and drainage pipeline also includes a seismic-resistant component 3. The seismic-resistant component 3 is correspondingly arranged with the clamping plate 22. The seismic-resistant component 3 includes an elastic element 31 and a buffer plate 32. The buffer plate 32 is located between the clamping plate 22 and the fixed half-ring 21. The extension and retraction direction of the elastic element 31 is parallel to the second direction. The elastic element 31 is fixedly connected between the clamping plate 22 and the buffer plate 32. The buffer plate 32 is slidably connected to the fixed half-ring 21 along the second direction. In this embodiment, the elastic element 31 is a compression spring. By setting the elastic element 31 and the buffer plate 32, when the pipeline is subjected to pressure under the action of the elastic element 31, the elastic element 31 is compressed. The elastic element 31 can buffer the force on the pipeline, thereby reducing the impact force transmitted to the pipeline. The buffer plate 32 is slidably connected to the fixed half-ring 21 along the second direction, further driving the clamping plate 22 to slide, so that the clamping plate 22 clamps and fixes the pipelines at different distances.

[0030] Reference Figure 2 In order to drive the buffer plate 32 to slide in the second direction, the seismic structure of the building water supply and drainage pipe also includes a first screw 4. The first screw 4 is threaded to the fixed half ring 21. The axis of the first screw 4 is parallel to the second direction. One end of the first screw 4 passes through the side wall of the fixed half ring 21 and is rotatably connected to the buffer plate 32. The other end is located on the side of the fixed half ring 21 away from the buffer plate 32. A rotating seat 321 is fixedly connected to one side of the buffer plate 32. The rotating seat 321 has a rotating groove 322 for accommodating the first screw 4. One end of the first screw 4 is located in the rotating groove 322 and is rotatably connected to the buffer plate 32. Rotating the first screw 4 drives the buffer plate 32 to slide in the second direction, which in turn drives the clamping plate 22 to slide in the second direction.

[0031] Reference Figure 2In order to guide the sliding of the buffer plate 32 along the second direction, the seismic structure of the building water supply and drainage pipeline also includes a guide rod 5. The guide rod 5 is parallel to the second direction. One end of the guide rod 5 passes through the fixed half ring 21 and is located in the fixed area 211. The buffer plate 32 is sleeved on the guide rod 5 and slides along the length of the guide rod 5. The guide rod 5 guides the sliding of the buffer plate 32 along the second direction.

[0032] Reference Figure 2 Since the pipe cross-section is cylindrical, in order to increase the contact area between the clamping plate 22 and the pipe, an arc-shaped groove 221 is provided through the two clamping plates 22 on the side that are close to each other along the third direction, so that the groove wall of the arc-shaped groove 221 fits against the outer wall of the pipe, thereby improving the clamping stability of the pipe.

[0033] Reference Figure 2 and Figure 3 To further connect the support frame 1 and the fixing component 2, each fixing half-ring 21 is fixed to the support frame 1 by a mounting component 6. The mounting component 6 includes an upper locking nut 61, a lower locking nut 62, a sliding seat 63, and two second screws 64. The second screws 64 are parallel to the second direction. Each fixing half-ring 21 has a second screw 64 on both sides. One end of the second screw 64 is fixedly connected to the sliding seat 63. Each fixing half-ring 21 has mounting seats 212 fixedly connected to both ends. The two mounting seats 212 pass through and slide along the axis of the second screws 64. The two second screws 64 have opposite threads. The upper locking nut 61 and the lower locking nut 62 are threadedly connected to the second screws 64. Two mounting seats are clamped between the upper locking nut 61 and the lower locking nut 62. A sliding seat 63 is fixedly connected to the bottom wall of the second screws 64. A first groove 111 is opened on the top wall of the support rod 11 along the first direction. The sliding seat 63 slides in the first groove 111 along the first direction. A second groove 121 for the sliding seat 63 to slide is opened on the top wall of the extension rod 12 along the first direction. The second groove 121 is connected to the first groove 111 along the first direction. Reference Figure 3 and Figure 4 In this embodiment, the sliding seat 63 has an "I" shaped cross section. The sliding seat 63 can slide in the first sliding groove 111 or in the second sliding groove 121. The sliding seat 63 is fixed to the support rod 11 by the first locking bolt 65. The sliding seat 63 is also fixed to the extension rod 12 by the first locking bolt 65. The number of installation components 6 and fixing components 2 can be set according to the number of pipes. The sliding seat 63 can be slid according to the position of the pipe, and the position of the fixing components 2 can be adjusted to achieve clamping and fixing of the pipe.

[0034] Reference Figure 3 , Figure 4 and Figure 5To enable the extension rod 12 to slide along the support rod 11, one end of the extension rod 12 is connected to a first slider 124. The first groove 111 passes through the end wall of the support rod 11 in the first direction. A limiting block 112 is fixedly connected to the end wall of the support rod 11. The first slider 124 is located in the first groove 111 and slides along the groove wall of the first groove 111. The limiting block 112 blocks the first slider 124 from sliding out of the first groove 111. The first slider 124 passes through a third groove 1241 in the first direction for the sliding seat 63 to slide. The third groove 1241 is connected to both the first groove 111 and the second groove 121. Thus, one side of the sliding seat 63 passes through the first groove 111 and the third groove 1241 in sequence and enters the second groove 121. In this embodiment, the first groove 111 is an inverted T-shaped groove.

[0035] Reference Figure 4 When there are multiple pipelines at the construction site, the height of the pipelines may vary. The height of the fixing component 2 can be adjusted by sliding the mounting seat 212. When the height of the fixing half-ring 21 changes, in order to further support the fixing half-ring 21, the seismic structure of the building water supply and drainage pipeline also includes a telescopic rod 7. The movable section of the telescopic rod 7 is fixedly connected to the fixing half-ring 21, and the fixed section of the telescopic rod 7 is fixedly connected to the sliding seat 63. The ends of the fixed section and the movable section of the telescopic rod 7 that are close to each other are slidably connected along the second direction. The fixed section and the movable section of the telescopic rod 7 are fixed together by screws. In this embodiment, two telescopic rods 7 are provided between each sliding seat 63 and the fixing component 2.

[0036] Reference Figure 5 and Figure 6 To further adjust the number of fixing components 2 according to the number of pipes, an extension rod 12 is slidably connected to both ends of the support rod 11. To achieve fixation with the wall, an installation plate 122 is fixedly connected to the end of the extension rod 12 away from the support rod 11. The extension rod 12 and the support rod 11 are fixed by the second locking bolt 123. Depending on the width of the wall, the extension rods 12 at both ends of the support rod 11 can be slid to abut against the wall, and the installation plate 122 can be fixed to the wall by bolts.

[0037] It should be noted that if the number of pipes is small, the fixing component 2 may not be installed on the extension rod 12, and the extension rod 12 may exist as a structure fixed to the wall.

[0038] Reference Figure 6In some construction environments, pipes need to be laid inside the ceiling. To further improve the stability of the pipes, the extension rod 12 is rotatably connected to the first slider 124. Specifically, the limiting block 112 is located on both sides of the support rod 11. The extension rod 12 is parallel to the third direction along the rotation axis of the first slider 124. There is space between the two limiting blocks 112 for the extension rod 12 to rotate. In order to allow the extension rod 12 to rotate, two fixing seats 631 are fixedly connected to the side of the first slider 124 near the extension rod 12. The extension rod 12 is rotatably connected between the two fixing seats 631. The side wall of the fixing seat 631 is in contact with the side wall of the limiting block 112. When the extension rod 12 slides to the end of the support rod 11 and abuts against the limiting block 112, the extension rod 12 can be rotated to be perpendicular to the support rod 11, and one end of the extension rod 12 is located above the support rod 11. The mounting plate 122 is fixed to the top wall of the ceiling with bolts. The two extension rods 12 can exist as a hanging rod structure, thereby realizing the fixation of the pipe. Reference Figure 6 In other construction environments, such as industrial plants or warehouses, where the aesthetic requirements for pipe installation are not high, some drainage pipes may be installed exposed along the ground or at a certain height above the ground. In this case, the extension rod 12 can be rotated to be perpendicular to the support rod 11, and the extension rod 12 can be rotated to be below the support rod 11. The mounting plate 122 is fixed to the ground with bolts. At this time, the two extension rods 12 can serve as a structure to support the support rod 11, further supporting the pipe. That is, by rotating the extension rod 12, the support and fixation of the pipe can be adapted to different construction environments.

[0039] The implementation principle of the seismic structure of a building water supply and drainage pipeline in this application embodiment is as follows: According to the on-site construction environment and the actual number of pipelines, slide the extension rod 12 to extend the length of the support rod 11, adjust the angle of the extension rod 12, install the same number of fixing components 2 as the number of pipelines, slide the sliding seat 63 in the first sliding groove 111 or the second sliding groove 121, adjust the height of the fixing half ring 21 according to the height of the pipeline so that the pipeline is located between the two clamping plates 22, and rotate the first screw 4 according to the diameter of the pipeline so that the two clamping plates 22 clamp and fix the pipeline. When the extension rod 12 is parallel to the support rod 11, the mounting plate 122 is fixed to the side wall of the wall by bolts. When the extension rod 12 is perpendicular to the support rod 11, the mounting plate 122 is fixed to the ground by bolts.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
