Description

Technical Field

[0001] The invention relates to the field of earthquake-proof structures for building construction, and in particular to a flexible piping system for an earthquake-isolation structure and a laying method thereof. Background Art

[0002] In traditional building design, pipelines are usually fixed directly to the structure of the building. However, when natural disasters such as earthquakes occur, buildings will experience varying degrees of displacement and vibration, causing damage to the pipeline system and even secondary disasters. To solve this problem, seismic isolation technology has gradually been applied to the design of buildings to reduce the impact of earthquakes on the internal facilities of the building. However, the existing seismic isolation measures are not perfect enough to protect the pipeline system, especially at the connection between the pipeline and the building structure, where there is a lack of effective solutions.

[0003] Therefore, in order to solve the above-mentioned problems, a seismic isolation structure flexible piping system and a laying method thereof are specifically proposed. Summary of the invention

[0004] The present invention is aimed at the above-mentioned problems and specifically designs a flexible piping system for a seismic isolation structure and a method for laying it. The present invention connects the upper and lower pipes by installing a vertical flexible connector, installs a seismic-proof fixed stand on the upper pipe, and arranges sliding supports, limit devices and vibration isolation devices on the lower part. This can effectively improve the seismic resistance and safety of the seismic isolation building's post-earthquake piping system and reduce the possibility of pipeline damage.

[0005] To achieve the above-mentioned purpose, the present invention provides a flexible pipe system for a seismic isolation structure, comprising: a pipe, a vertical flexible connecting device, a seismic-proof fixed platform and a sliding support device, wherein the two ends of the pipe are respectively installed on the building wall through the seismic-proof fixed platform and the sliding support device, the pipe is slidably connected to the sliding support device, and the vertical flexible connecting device is arranged in the middle of the pipe.

[0006] Through the above method, the earthquake-proof fixed platform can absorb the seismic energy generated by disaster processes such as earthquakes and reduce the transmission of vibrations.

[0007] Furthermore, the pipeline, the vertical flexible connection device, the shockproof fixed platform and the sliding support device, the two ends of the pipeline are respectively installed on the building wall through the shockproof fixed platform and the sliding support device, the pipeline is slidably connected to the sliding support device, and the vertical flexible connection device is arranged in the middle of the pipeline.

[0008] Furthermore, the sliding support device includes: an upper buckle, a lower buckle and a bolt, the upper buckle and the lower buckle are arc-shaped structures and are arranged on the pipe in a clamp-like manner, the lower buckle is fixedly connected to the shockproof device, the two sides of the upper buckle and the lower buckle are fixedly connected by the bolt, and the pipe is slidably connected between the upper buckle and the lower buckle.

[0009] Through the above method, the upper buckle and the lower buckle form a hoop-shaped pipe structure. The pipe is limited by the sliding support device, but can slide back and forth. The pipe cannot escape from the range of the buckle. When vibrating, the length can be automatically adjusted by sliding, and the pipe will not be stretched and damaged.

[0010] Furthermore, the vertical flexible connection device includes a bellows and a connector, and both ends of the bellows are connected to the pipeline through the connector.

[0011] In the above manner, the middle portion is a corrugated tube, which has higher toughness when stretched.

[0012] Furthermore, it also includes a limiting device, which is sleeved on the pipeline and located between the sliding support device and the vertical flexible connection device.

[0013] The above method is used to limit the maximum safe displacement range of the pipeline and prevent damage caused by excessive movement.

[0014] Furthermore, the anti-vibration fixed stand includes a support leg and a baffle, one side of the baffle is fixedly connected to the support leg, the support leg is fixedly connected to the building wall, and the pipeline is placed on the baffle.

[0015] Furthermore, the shockproof device includes: a bottom frame, a top frame and an elastic member, the bottom frame is fixedly connected to the building wall, the top frame is sleeved on the bottom frame and slidably connected to the bottom frame, and the two ends of the elastic member are respectively fixedly connected to the bottom and top of the inner walls of the bottom frame and the top frame.

[0016] Through the above method, when vibration occurs, the elastic force of the spring can alleviate the damage caused by the vibration to the upper sliding support device and the pipeline.

[0017] The present application also discloses a method for laying a seismic isolation structure flexible piping system, comprising the following steps: Step 1: Install the earthquake-proof fixed stand on the building wall, and install the upper pipe between the earthquake-proof fixed stand and the building wall; Step 2: Connect the end of the upper pipe to the corrugated pipe through a connector, and connect the other end of the corrugated pipe to the lower pipe through the connector; Step 3: Install a limit device at the elbow of the lower pipe; Step 4: a sliding support device is arranged on the lower pipe, the anti-vibration device is fixedly connected to the building wall, and the sliding support device is fixedly connected to the anti-vibration device.

[0018] Furthermore, before installation, the net height of the building isolation layer is determined according to the functional purpose of the building isolation layer, and the position and length of the pipe and the corrugated pipe are determined.

[0019] In summary, the seismic isolation structure flexible piping system and the laying method thereof of the present invention have the following advantages and beneficial technical effects: 1. The flexible piping system of a seismic isolation structure of the present invention can connect the upper and lower pipes by installing a vertical flexible connector, installing a seismic fixing stand on the upper pipe, and arranging a sliding support, a limit device and a vibration isolation device on the lower part, which can effectively improve the seismic performance and safety of the seismic isolation building post-earthquake piping system and reduce the possibility of pipeline damage; 2.
