Description

Technical Field

[0001] The utility model relates to the field of seismic resistance technology of building structures, and in particular to a wall-mounted seismic isolation structure for pipeline systems. Background Technology

[0002] In building water supply, drainage, fire protection, and ventilation piping systems, risers are typically laid vertically along the walls and directly fixed to the building walls using supports. When an earthquake occurs, the horizontal and vertical vibrations generated by the building structure are directly transmitted to the pipes through traditional rigid supports, causing a series of problems: First, stress concentration easily occurs at the connection between the pipe and the support, leading to cracks or deformation; second, because the connection between the pipe and the wall is rigid, there is a lack of effective energy dissipation mechanisms, making it impossible to attenuate earthquake energy; third, when multiple pipes are arranged in parallel, due to the lack of overall constraint, the vibrations of each pipe are asynchronous, making them prone to collisions.

[0003] While the simple elastic supports used in the existing technology can provide some vertical seismic isolation, they still have many shortcomings: the horizontal seismic isolation effect is limited and there is a lack of effective energy dissipation mechanism; they are poorly adaptable to pipe systems attached to the wall; they lack overall control in multi-pipe systems; and the seismic isolation devices have poor durability and their performance degrades significantly after long-term use.

[0004] Therefore, there is an urgent need to develop a wall-mounted seismic isolation structure that can effectively address the above problems in order to improve the safety and reliability of pipeline systems under seismic loads. Utility Model Content

[0005] The purpose of this invention is to provide a wall-mounted seismic isolation structure for pipeline systems, which aims to solve the technical problems of traditional wall-mounted pipelines being prone to damage, instability, and connection failure during earthquakes due to insufficient rigid connections and seismic isolation measures.

[0006] To achieve the above objectives, the present invention adopts the following technical solution.

[0007] A riser wall-mounted seismic isolation structure is used to isolate a group of pipes from vibration. It includes steel supports, strip supports, and vibration isolators. A set of steel supports is arranged at intervals along the long axis of the wall. Each steel support is inverted L-shaped, with its vertical side connected to the wall and its horizontal end extending beyond the outer surface of the pipe. Two strip supports are provided, clamped on the inner and outer sides of the group of pipes respectively. Each strip support includes a vertical section and a horizontal section, with the vertical section attached to the side wall of the group of pipes. Tie bolts are spaced between the two strip supports. Two sets of vibration isolators are provided, arranged on the inner and outer sides of the group of pipes respectively, and correspondingly installed on the top of the steel supports, with the upper end of the vibration isolator supported by the bottom of the horizontal section.

[0008] Preferably, the bottom of the steel support is provided with diagonal bracing to enhance the support's resistance to overturning.

[0009] Preferably, the vibration isolator includes a base plate, a top plate, insert plates, clamping plates, and springs; a short column is provided in the middle of the top surface of the base plate; the spring is sleeved on the outside of the short column and fixedly connected to the base plate, with the top of the spring extending beyond the top of the short column and having a connector at its top; two clamping plates are provided, spaced apart on the top surface of the base plate and located on both sides of the spring; the horizontal cross-section of each clamping plate is arc-shaped, and an energy-dissipating pad is provided on its inner side; the top plate is located above the connector, and the two are connected by connecting bolts; two insert plates are provided at the bottom of the top plate and inserted into the inner sides of the two clamping plates; the clamping plates are in contact with the corresponding energy-dissipating pads, and a gap is left between the bottom end of the clamping plate and the base plate to allow the clamping plates to undergo elastic deformation and dissipate energy during an earthquake.

[0010] Preferably, the vibration isolator is connected to the horizontal plate segment by connecting bolts, which facilitates installation and maintenance.

[0011] Preferably, the vertical plate segment is connected to the wall by pre-embedded bolts to ensure the stability of the plate support.

[0012] Preferably, the cross-section of the strip support is inverted L-shaped or horizontal T-shaped to adapt to different pipeline layout requirements.

[0013] Compared with the prior art, the present invention has the following features and beneficial effects.

[0014] 1. This utility model connects multiple pipes into a whole through strip supports on both the inner and outer sides and tie bolts, preventing asynchronous vibration of the pipes. The vertical plate section of the strip support is close to the side wall of the pipe, providing effective lateral restraint and preventing excessive horizontal displacement of the pipe. The two strip supports form a clamping structure, ensuring the overall stability of the pipeline system and strong overall collaborative performance. Simultaneously, this utility model adopts an inverted L-shaped steel bracket design, ensuring reliable connection with the wall and providing an installation platform for vibration isolators. The horizontal side of the steel bracket extends beyond the outer side of the pipe, providing sufficient installation space for the outer vibration isolators. The diagonal bracing further enhances the stability and load-bearing capacity of the steel bracket.

[0015] 2. This utility model has multiple vibration isolation and energy dissipation mechanisms. The spring in the vibration isolator provides effective buffering. At the same time, the friction and elastic deformation of the clamping plate and the energy dissipation pad provide vibration isolation and energy dissipation capabilities. The gap design between the bottom end of the clamping plate and the base plate allows the clamping plate to deform moderately during an earthquake, further dissipating energy.

[0016] 3. The vibration isolator of this utility model adopts a modular design, which facilitates factory production and on-site installation. The design of the connecting bolts facilitates adjustment, replacement and maintenance. The strip support can be flexibly adjusted according to the number and size of the pipeline, which is highly adaptable. The energy dissipation gasket is made of wear-resistant material to ensure stable performance and durability over a long period of use. The spring is set outside the short column to prevent spring instability and improve service life. All connection parts adopt reliable connection methods to ensure safety under seismic action.
