Description

Technical Field

[0001] This invention relates to the field of seismic bracing technology, specifically to a seismic bracing system for building pipelines. Background Technology

[0002] With the rapid modernization of urban and rural areas in my country, modern building standards are constantly improving, and the number of non-structural components in buildings is gradually increasing. To meet residents' water needs, corresponding pipes are installed in buildings for water supply and drainage. These water pipes are mainly divided into metal pipes, plastic-coated metal pipes, and plastic pipes, depending on the specific requirements. The casualties, economic losses, and loss of building function caused by these non-structural components during earthquakes have drawn significant attention. Building pipelines, as fundamental non-structural components ensuring building functionality, bear the responsibility for fire protection and water resource transportation. To guarantee the functionality of buildings, it is necessary to improve the seismic resistance of pipelines, leading to the development of seismic bracing for building pipelines.

[0003] Chinese utility model patent with publication number "CN209671767U" discloses a novel seismic-resistant pipe support. The technical solution is as follows: This utility model relates to the field of seismic-resistant support technology, specifically to a novel seismic-resistant pipe support, including an upper support plate, a lower support plate, a connecting rod, a sleeve rod, a screw, a rotating shaft, an adjusting shaft, and a T-shaped connecting column. This device adjusts the rotation of the fourth bevel gear via a handle. The rotation of the fourth bevel gear drives the rotating shafts on both sides to rotate in opposite directions, thereby achieving the same rotation of the screws on both sides. Simultaneously, through the meshing of the bevel gears, the angle and speed of the screw rotation are ensured to be the same, thus ensuring that the upper support plate can move smoothly downwards. This ensures that the clamping force on both sides of the pipe is consistent, guaranteeing the clamping effect and preventing the upper support plate from bending or being damaged due to different clamping forces. The elastic pad prevents excessive clamping force from damaging the pipe and also prevents pipe swaying. The large bending radius of the inner sides of the upper and lower support plates allows for clamping pipes of different diameters. The T-shaped rods on both sides compress springs to alleviate the vibration experienced by the pipe.

[0004] Although this utility model can realize the installation of pipelines, the seismic resistance method is singular, and the stability and shock absorption effect between the pipeline and the bracket are poor. The connection between the rod and the C-shaped steel, although it helps to improve the structural strength of the C-shaped steel and the installation site to a certain extent, fails to provide further support for the lower support plate. Summary of the Invention

[0005] The purpose of this invention is to provide a seismic bracing for building pipelines to solve the problems mentioned in the background art: poor stability and shock absorption between pipelines and brackets, and a single seismic resistance method; the connection between the connecting rod and the fixed steel, although it helps to improve the structural strength of the fixed steel and the installation site to a certain extent, fails to provide further support for the pipeline support plate.

One end of the suspension rod on both sides of the support ring passes through the upper and lower parts of the corresponding auxiliary reinforcing plate through the through hole, and is fixed after passing through the left half ring connecting plate and the right half ring connecting plate through the connecting hole. The other end of the suspension rod is fixed to the installation position by expansion bolts. The lower part of the left half ring connecting plate and the right half ring connecting plate are respectively connected to the middle support plate. The front and rear ends of the middle support plate are respectively connected to the front ear plate and the rear ear plate. The front ear plate and the rear ear plate are respectively connected to the front tie rod and the rear tie rod. The middle section of the front tie rod and the rear tie rod are respectively provided with connecting plates, which are connected to the adjacent suspension rod. The front tie rod and the rear tie rod are respectively connected to the installation position by connectors.

[0008] Preferably, the suspension rod includes a left-end suspension rod, a right-end suspension rod, a left-middle suspension rod, and a right-middle suspension rod. The left-middle suspension rod and the right-middle suspension rod are respectively installed in the connecting holes in the middle of the left half-ring connecting piece and the right half-ring connecting piece. The left-end suspension rod and the right-end suspension rod are respectively installed in the connecting holes near the beginning and end of the left half-ring connecting piece and the right half-ring connecting piece. The top of the suspension rod is also provided with a nut corresponding to the expansion bolt at the installation position.

[0009] Preferably, the pouch strip is further connected to an anti-agglomerate strip, the inner wall of which is flush with the inner wall of the pouch strip, and the outer wall of which fits against the support ring.

[0010] Preferably, the ring strip is connected to an injection cylinder, and the injection cylinder is connected to an injection valve, through which an elastic material can be injected into the ring strip.

[0011] Preferably, the connecting rings are connected by connecting bolts, and a sealing gasket is provided between the connecting rings.

[0012] Preferably, the bottom end of the suspension rod is provided with a spring-loaded washer and a nut that is installed on the connecting hole of the left half-ring connecting piece and the right half-ring connecting piece.

[0013] Preferably, the connecting plate is connected to a horizontal tension rod, and the other end of the horizontal tension rod is fitted into the middle of the suspension rod that passes through the connecting holes at both ends of the left half-ring connecting piece and the right half-ring connecting piece.

[0014] Preferably, the front tie rod and the rear tie rod are hinged in the hinge seat, and a top plate is connected above the hinge seat. The top plate is connected to the installation position by bolts.

[0015] Preferably, a protective cap is connected to the injection valve.

[0016] Compared with the prior art, the present invention has the following technical effects:

[0017] 1. The seismic support for building pipelines described in this invention involves laying a ring-shaped support strip inside a supporting ring during pipeline installation. The supporting ring has a fully enclosed structure, providing support for the pipeline while increasing its stability. The pipeline is placed inside the ring-shaped support strip, which is pre-filled with a small amount of elastic material. The ring-shaped support strip is then connected into a loop using two connecting rings. After connection, the position of the supporting ring is adjusted, and then the supporting ring is fixed. Elastic material is continuously injected into the ring-shaped support strip through a pressure injection valve to maintain a certain pressure, thus supporting the pipeline. The injection of elastic material is then stopped. When the pipeline displaces due to an earthquake and exerts force on the ring-shaped support strip, the elastic material can change its shape or size to adapt to the pipeline; and it can return to its original shape when the force disappears, maintaining pipeline stability. The device has openings on the left and right sides of the supporting ring with opposite directions. The auxiliary reinforcing plate, bent into a C-shape, has through holes on its upper and lower surfaces. The suspension rods pass through these holes. When the suspension rods shift due to vibration, the auxiliary reinforcing plate can use its elasticity to apply a force opposite to the direction of displacement to the suspension rods, thus mitigating the vibration and improving overall stability. It also enhances the structural strength between the left middle suspension rod and the two left-end suspension rods, as well as between the right middle suspension rod and the two right-end suspension rods. Furthermore, the left and right support plates of this seismic-resistant building pipeline support are connected to front and rear tie rods. Through the cooperation of these tie rods, the seismic-resistant building pipeline support can move synchronously with the pipeline when it undergoes axial displacement due to an earthquake, strengthening and fixing the connection between the seismic-resistant building pipeline support and the installation site. Simultaneously, the connection between the tie rods and the middle support plate provides support for the left and right half-ring connecting plates, further enhancing the stability of the pipeline.

[0018] 2. The seismic bracing for building pipelines of the present invention has connecting holes at both ends and in the middle of the left and right half-ring connecting plates, and the connecting holes are connected to suspension rods. The relative structure between the three left suspension rods and the three right suspension rods formed by this installation is relatively stable, which improves the structural strength of the entire device.

[0019] 3. The seismic bracing for building pipelines described in this invention includes anti-agglomerate strips fixedly connected to both ends of the bladder ring strip. The inner wall of the anti-agglomerate strip is flush with the inner wall of the bladder ring strip, and the outer wall of the anti-agglomerate strip contacts the support ring. The fit between the anti-agglomerate strip, the support ring, and the bladder ring strip can effectively prevent the support ring from scratching the pipeline, protect the pipeline structure, and make the device safer to use.

[0020] 4. The seismic support for building pipelines of the present invention has an opening at the top of the ring strip, and two tightly clamped connecting rings are provided at the opening. The two connecting rings are connected by bolts, and a sealing gasket is provided in the middle. The presence of the sealing gasket makes the fit between the connecting rings tighter, improves the sealing effect between the two connecting rings, and protects the integrity of the support ring structure.

[0021] 5. The seismic bracing for building pipelines of the present invention includes spring washers between the left middle hanger, right middle hanger, left end hanger, and right end hanger and the connection holes of the left half-ring connecting piece and the right half-ring connecting piece, so that the connection between the hanger and the left half-ring connecting piece and the right half-ring connecting piece is tighter, and provides longitudinal elasticity for the entire device and pipeline during an earthquake, effectively resisting vibration.

[0022] 6. The seismic bracing for building pipes of the present invention has connecting plates in the middle sections of the front and rear tie bars, and the connecting plates are connected to horizontal tension rods. The other end of the horizontal tension rod is fitted into the middle of the suspension rod that passes through the connecting holes at both ends of the left and right half-ring connecting plates. When an earthquake occurs, the force generated by the vibration can be transmitted from the front and rear tie bars to the suspension rod, so that the load is evenly distributed. The front tie bars, rear tie bars and suspension rods are interconnected to improve the seismic performance.

[0023] 7. The seismic support for building pipelines described in this invention includes a protective cap threaded onto the pressure injection valve. The protective cap is made of transparent material, which facilitates the monitoring of the pressure injection valve by staff and allows observation of its status, thereby enhancing the protection of the pressure injection valve and improving operational safety.

[0030] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present application and with reference to the accompanying drawings.

[0031] This invention discloses a seismic-resistant support for building pipelines, comprising a placement device. The placement device includes a support ring 9, which has a fully enclosed structure, providing support for the pipeline while increasing its stability. A retaining ring 9 contains a coiled ring 10 filled with an elastic material. Preferably, the elastic material filling the retaining ring 10 can be liquid silicone or liquid rubber. Through the filling of the retaining ring 10 with elastic material, when the pipeline displaces due to an earthquake and exerts force on the retaining ring, the elastic material can change its shape or size to adapt to the pipeline, and return to its original shape when the force disappears, thereby maintaining pipeline stability. This also improves the stability between the support ring 9 and the pipeline to be supported, enhancing the shock absorption effect. This design avoids scratching the pipeline with the support ring 9, making it safer to use. The upper part of the ring strip 10 is open, and two tightly fitting connecting rings 12 are provided at the opening, allowing the ring strip 10 to be connected into a ring shape. Several lifting rods are connected to both sides of the support ring 9. The support ring 9 is surrounded by a left half-ring connecting piece 4 and a right half-ring connecting piece 5. The left half-ring connecting piece 4 and the right half-ring connecting piece 5 are respectively provided with at least two connecting holes near the beginning and end and the middle. On the left and right sides of the support ring 9, auxiliary reinforcing pieces 8 with opposite opening directions and bent into a C-shape are provided. The upper and lower surfaces of the auxiliary reinforcing pieces 8 are provided with through holes. One end of the lifting rod on both sides of the support ring 9 passes through the through hole and through the upper and lower surfaces of the corresponding auxiliary reinforcing piece 8, and passes through the connecting hole through the left half-ring connecting piece 4 and the right half-ring connecting piece 5. The right half-ring connecting piece 5 is then fixed. When the suspension rod shifts due to vibration, the auxiliary reinforcing piece 8 can use its own elasticity to apply a force opposite to the direction of displacement to the suspension rod, thus reducing vibration and improving overall stability. The other end of the suspension rod is fixed to the installation position by expansion bolts. The left half-ring connecting piece 4 and the right half-ring connecting piece 5 are respectively connected to intermediate support plates 16. The front and rear ends of the intermediate support plate 16 are respectively connected to front ear plates 17 and rear ear plates 18. The front ear plates 17 and rear ear plates 18 are respectively connected to front tie rods 14 and rear tie rods 15. Through the cooperation of the front tie rods 14 and rear tie rods 15, the seismic brace for the building pipeline can move synchronously with the pipeline when it undergoes axial displacement due to an earthquake, ensuring a secure connection between the seismic brace and the installation site. To strengthen the fixation, the connection between the front tie rod 14, the rear tie rod 15, and the intermediate support plate 16 provides support for the left half-ring connecting piece 4 and the right half-ring connecting piece 5, further enhancing the stability of the pipeline. Connecting plates 20 are respectively provided in the middle sections of the front tie rod 14 and the rear tie rod 15, connecting to adjacent hanger rods. The front tie rod 14 and the rear tie rod 15 are respectively connected to the installation position via connectors. The hanger rods include a left-end hanger rod 6, a right-end hanger rod 7, a left-middle hanger rod 2, and a right-middle hanger rod 3. The left-middle hanger rod 2 and the right-middle hanger rod 3 are respectively installed in the connecting holes in the middle of the left half-ring connecting piece 4 and the right half-ring connecting piece 5. The left-end hanger rod 6 and the right-end hanger rod 7 are respectively installed in the connecting holes near the beginning and end of the left half-ring connecting piece 4 and the right half-ring connecting piece 5.The relative structure between the three left and three right suspension rods formed by this installation is relatively stable, improving the structural strength of the entire device. The top of each suspension rod is also equipped with a long external hexagonal nut 1 corresponding to the expansion bolt at the installation position. Anti-agglomerate strips 23 are fixedly connected to both ends of the ring strip 10. The inner wall of the anti-agglomerate strip 23 is flush with the inner wall of the ring strip 10, and the outer wall of the anti-agglomerate strip 23 fits against the support ring 9. This fit between the anti-agglomerate strip 23, the support ring 9, and the ring strip 10 effectively prevents the support ring from scratching the pipeline, protecting the pipeline structure and ensuring greater safety during device use. A pressure injection cylinder 26 is connected to the strip 10, and a pressure injection valve 27 is connected to the pressure injection cylinder 26. Elastic material can be injected into the ring strip 10 through the pressure injection valve 27. The connecting rings 12 are connected by connecting bolts 13, and a sealing gasket 25 is provided between the connecting rings 12. The presence of the sealing gasket 25 makes the fit between the connecting rings 12 tighter, improves the sealing effect between the two connecting rings 12, and protects the integrity of the support ring 9. The left middle suspension rod 2, right middle suspension rod 3, left end suspension rod 6, and right end suspension rod 7 are all connected to the connecting holes of the left half-ring connecting piece 4 and the right half-ring connecting piece 5. A spring-loaded washer 24 is provided to ensure a tighter connection between the suspension rod and the left half-ring connecting piece 4 and the right half-ring connecting piece 5. During an earthquake, this provides longitudinal elasticity to the entire device and pipeline, effectively resisting vibration. The connecting plate 20 is connected to a horizontal tension rod 19. The other end of the horizontal tension rod 19 is fitted into the middle of the suspension rod, which passes through the connecting holes at both ends of the left half-ring connecting piece 4 and the right half-ring connecting piece 5. Furthermore, one of the two left-end suspension rods 6 near the front and one of the two right-end suspension rods 7 near the front are respectively connected to two front tension rods 14. One of the two left-end suspension rods 6 near the rear and one of the two right-end suspension rods 7 near the rear are respectively connected to two rear tie rods 15. The front tie rod 14 and the rear tie rod 15 are hinged within the hinge seat 22. A top plate 21 is connected above the hinge seat 22, and the top plate 21 is connected to the installation position by bolts. A protective cap 28 is threaded onto the pressure injection valve 27. The protective cap 28 is made of transparent material, which facilitates the monitoring of the pressure injection valve by the operator and allows observation of the valve's status, thus strengthening the protection of the pressure injection valve and improving operational safety.

[0032] In summary, the installation process of this seismic bracing for building pipelines is as follows: First, mark the dimensions at the location of the pipeline to be supported, then drill installation grooves for installing the left middle hanger 2, right middle hanger 3, left end hanger 6, and right end hanger 7. Insert expansion bolts into the installation grooves, thread the long external hexagonal nut 1 onto the expansion bolts, and then tighten the expansion bolts in the installation grooves by rotating the long external hexagonal nut 1. Thread the left middle hanger 2, right middle hanger 3, left end hanger 6, and right end hanger 7 into the corresponding long external hexagonal nut 1. Then, fit the auxiliary reinforcing plate 8 and the flat tension rod 19 onto the left middle hanger 2, right middle hanger 3, left end hanger 6, and right end hanger 7. Finally, complete the pre-installation of the left half-ring connecting piece 4 and the right half-ring connecting piece 5, and lay the ring strip 10 on the support ring. When laying the pipeline, place the pipeline inside the ring strip 10. After pre-filling a small amount of elastic material inside the ring strip 10, connect the ring strip 10 into a ring through two connecting rings 12. After the connection is completed, adjust the position of the support ring 9, and then fix the support ring 9. Continue to inject elastic material into the ring strip 10 through the injection valve 27 to maintain a certain pressure in the elastic material inside the ring strip 10, so as to support the pipeline. Then stop the injection of elastic material and install the protective cap 28 on the injection valve 27. Finally, fix the front tie rod 14 and the rear tie rod 15 at the installation site. During vibration, the seismic support for rural building construction ensures the stability of the pipeline position through structural strength, and at the same time consumes the energy of pipeline vibration through the deformation of the elastic material, thereby achieving pipeline vibration reduction.

[0033] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the protection scope of the present invention.
