Description

Technical Field

[0001] The utility model relates to the technical field of building seismic isolation layer pipeline connection, in particular to a flexible connection structure for seismic isolation layer pipelines in a seismic isolation building. Background Art

[0002] Building seismic isolation is a system that effectively reduces the destructive effects of horizontal earthquakes on the upper structure by setting up an isolation layer composed of seismic isolators, damping devices, etc. between the foundation or lower part of the building and the upper structure, thereby achieving all-round protection for the building itself and its internal facilities. After the earthquake, the building can continue to be used with simple repairs or no repairs.

[0003] While structural earthquake resistance is widely practiced and widely implemented, flexible pipeline connections, another crucial element in seismic isolation buildings, are less commonly used and implemented. Construction companies lack experience, and installation quality risks exist. Whether pipelines function properly after an earthquake has a significant impact on both building function and safety, ultimately impacting the overall safety and sustainable use of seismic isolation buildings.

[0004] Therefore, in order to avoid secondary disasters caused by damage to the seismic isolation layer pipeline and respond to the country's sustainable development strategy, we urgently need to develop more seismic-resistant systems for pipeline flexible connection structures to solve the above problems.

The connecting flange 23 is fixedly connected to the end of the fixed pipe 1.

[0025] The lifting structure 6 includes a connecting frame 61, a guide rod 62, a limit baffle 63, a lifting chain 64, and an annular clamp 65; the connecting frame 61 is fixedly connected to the upper seismic isolation layer 4, the guide rod 62 is inserted between the two connecting frames 61 and is slidably connected to the connecting frames 61, the two ends of the guide rod 62 are respectively fixedly connected to a limit baffle 63, one end of the lifting chain 64 is sleeved on the guide rod 62, and the other end of the lifting chain 64 is connected and fixed to the annular clamp 65, and the annular clamp 65 is clamped and fixed to the fixed pipe 1.

When connecting the fixed pipe 1 and the seismic isolation pipe structure 2, the joints are staggered 500mm after meeting a minimum distance of 1500mm from the wall to facilitate inspection and maintenance.

[0027] The technical solution of this embodiment 1 is suitable for use when the shock-absorbing layer 4 is used to connect water supply, fire protection, and tap water pipes with relatively high pressure. The seismic isolation pipe structure 2 needs to meet the deformation requirement of about 400 mm in any horizontal direction. The seismic isolation pipe structure 2 in embodiment 1 is composed of a stainless steel bellows 21 with a stainless steel mesh sleeve 22 woven outside, and the two ends are connected by connecting flanges 23.

[0030] The hoisting structure 6 includes a mounting base 601 and a spring damper 602 . The mounting base 601 is fixedly connected to the upper seismic isolation layer 4 . One end of the spring damper 602 is mounted on the mounting base 601 , and the other end of the spring damper 602 is mounted on the fixed pipe 1 .

[0031] In the technical solution of Example 2, as the diameter of the fixed pipe 1 increases, the diameter of the corresponding seismic isolation pipe structure 2 increases accordingly, thereby reducing the probability of damage to the fixed pipe 1. When connecting the fixed pipe 1 and the seismic isolation pipe structure 2, the joints are staggered 500mm after meeting a minimum distance of 1500mm from the wall to facilitate inspection and maintenance.

[0032] The technical solution of this embodiment 2 is suitable for use when the shock-absorbing layer 4 is connected to the wastewater, sewage and rainwater systems with lower pressure. The seismic isolation pipe structure 2 in embodiment 2 adopts a retractable seismic isolation PVC telescopic pipe with sealing ball heads 204 at both ends and a PVC inner pipe 201 and a PVC outer pipe 202 in the middle. A sealing ring 203 is installed between the PCV inner pipe 201 and the PVC outer pipe 202 to enhance the airtightness of the seismic isolation pipe structure 2 and prevent water leakage. The length of the telescopic joint of the seismic isolation pipe structure 2 can be adjusted to meet the axial telescopic deformation. The sealing ball heads 204 at both ends can rotate in multiple directions to meet the radial deformation requirements, forming a comprehensive deformation capacity to achieve normal use after the earthquake. The connecting part in the middle of the fixed pipe 1 is connected and fixed to the lifting structure 6. The lifting structure 6 in embodiment 2 is to fix the mounting base 601 on the upper seismic isolation layer 4. One end of the spring damper 602 is installed on the fixed pipe 1, and the other end is installed on the mounting base 601, so that the fixed pipe 1 is hoisted and fixed to the upper seismic isolation layer 4.
