Description

TECHNICAL FIELD

[0001] The utility model relates to building equipment technical field especially is related to a building anti shock support device. BACKGROUND

[0002] Traditional building anti shock devices, such as steel support, concrete shear wall etc. have the problem of insufficient energy dissipation capacity. In the prior art, damper relies on plastic deformation or speed trigger, and the maintenance cost is high. The seismic isolation support is high in cost and poor in adaptability to vertical earthquake.

[0003] Therefore, it is urgent to develop an anti shock support device considering stiffness, energy dissipation and repairability to solve the defects of traditional technology and prior art. SUMMARY

[0004] The utility model aims at providing a building anti shock support device, which can realize hierarchical energy dissipation, has been repaired after earthquake and has automatic reset capability.

[0005] In order to achieve the above purpose, the utility model provides a building anti shock support device, and the specific implementation scheme is as follows:

[0006] A building anti shock support device comprises a core support main body, the two ends of the core support main body are connected with a building main body through high-strength bolts, and a plurality of friction plates are stacked on the end of the core support main body.

[0007] Energy dissipation link beams are arranged on the two sides of the core support main body and are hinged with the core support main body.

[0008] A friction plate and a pre-pressed butterfly spring are arranged at the connection between the end of the core support main body and the building main body, one end of the butterfly spring abuts against the friction plate, and the other end abuts against the building main body.

[0009] A locking piece is arranged on the core support main body and is connected with the building main body.

[0010] This utility model discloses a seismic bracing device for buildings. Compared with existing technologies, it features energy-dissipating connecting beams on both sides of the core support body, hinged to the core support body. Friction plates and pre-compressed butterfly springs are installed between the core support body and the building structure. Locking devices are installed on the core support body and connected to the building structure. In actual seismic applications, during minor earthquakes, the rigidity of the core support body plays a major role in load-bearing and seismic resistance, while the energy-dissipating connecting beams and pre-compressed butterfly springs maintain elasticity. During moderate earthquakes, the energy-dissipating connecting beams undergo plastic deformation to dissipate energy, and several friction plates between the pre-compressed butterfly springs and the core support body begin to generate frictional activity. Energy is dispersed by sacrificing the energy-dissipating connecting beams to avoid damaging the core support body. During major earthquakes, the energy-dissipating connecting beams are completely damaged and broken, the locking devices unlock, and the friction plates continue to dissipate energy. After the earthquake, the support device can be quickly repaired by replacing the energy-dissipating connecting beams, achieving graded energy dissipation, post-earthquake repair, and automatic reset capabilities.

[0011] In some embodiments, the core support body has extension plates extending to both sides at both ends, and the core support body and the extension plates form an "I"-shaped cross section, with the energy dissipation connecting beam located between the extension plates at both ends.

[0012] The extension plates, in conjunction with the core support body, form an "I"-shaped cross-section, which improves the load-bearing capacity of the core support body. Furthermore, the energy-dissipating connecting beams are placed between the two extension plates to enhance the connection stability of the energy-dissipating connecting beams.

[0013] In some embodiments, the extension plate is provided with the high-strength bolt, and the extension plate at either end is provided with a mounting hole. The end of the energy-dissipating connecting beam is connected to the mounting hole by a connecting bolt. There is a movable distance between the connecting bolt and the mounting hole. The connecting bolt moves within the movable distance range to realize the hinge connection between the energy-dissipating connecting beam and the core support body.

[0014] By setting high-strength bolts on the extension plate, the connection between the core support body and the building body is improved in terms of convenience and stability. The movable distance between the mounting holes and the connecting bolts allows the connecting bolts to achieve the hinge between the energy dissipation beam and the core support body, as well as the plastic deformation of the energy dissipation beam.

[0015] In some embodiments, a V-shaped groove is provided in the middle of the energy-dissipating beam to allow the energy-dissipating beam to undergo plastic deformation.

[0016] By opening a V-shaped groove in the middle of the energy-dissipating connecting beam, the energy-dissipating connecting beam can undergo plastic deformation at the position of the V-shaped groove due to the vibration, thus improving the stability of the deformation.

[0017] In some embodiments, the locking member is a hydraulic cylinder fixed on the core support body, and a piston rod of the hydraulic cylinder is fixed in the building body.

[0018] By using the hydraulic cylinder as the locking member, controllability of locking and unlocking and stability of locking of the locking member are improved.

[0019] In some embodiments, the core support body is a high-strength low-yield-point steel plate or a fiber-reinforced concrete.

[0020] By using the high-strength low-yield-point steel plate or the fiber-reinforced concrete as the core support body, load capacity of the core support body is improved.

[0021] In some embodiments, the energy dissipation link beam is a high-strength low-yield-point steel plate or a shape memory alloy plate.

[0022] By using the high-strength low-yield-point steel plate or the shape memory alloy plate as the energy dissipation link beam, load capacity and plasticity of the energy dissipation link beam are improved.

[0023] Based on the above technical solutions, the utility model has the following beneficial effects relative to the prior art:

[0024] By arranging the energy dissipation link beam on both sides of the core support body, the energy dissipation link beam and the core support body are hinged, and the friction plate and the pre-pressed butterfly spring are arranged between the core support body and the building body, and the locking member connected with the building body is arranged on the core support body. In actual seismic use, the rigidity of the core support body plays a main load seismic role in small earthquakes, and the energy dissipation link beam and the pre-pressed butterfly spring are both elastic; in medium earthquakes, the energy dissipation link beam is plastically deformed to dissipate energy, and the several friction plates between the pre-pressed butterfly spring and the core support body begin to rub, energy is dispersed by damaging and sacrificing the energy dissipation link beam, and the core support body is prevented from being damaged; in large earthquakes, the energy dissipation link beam is completely damaged and broken, the locking member is unlocked and supports the continuous energy dissipation of the friction plate, and after the earthquake, the support device can be quickly repaired by replacing the energy dissipation link beam, hierarchical energy dissipation is realized, and the function of automatic resetting after repair is realized.
