Description

Technical Field

[0001] The utility model relates to a support, in particular to an embedded limited-position support that can be lifted away. Background Art

[0002] Earthquake is one of the important natural disasters that seriously endangers human survival. The use of seismic isolation technology can effectively reduce the horizontal seismic effect of the overall structure. At present, seismic isolation technology has been widely used in my country.

[0003] At present, a Chinese patent with the authorization announcement number CN218203858U discloses a shock-absorbing rubber bearing, which belongs to the field of bridge shock absorption technology, including a shock-absorbing rubber bearing, and the shock-absorbing rubber bearing includes a lower sealing plate and an upper sealing plate; two groups of buffer components are installed between the lower sealing plate and the upper sealing plate, and the buffer components include a lower connecting plate, an upper connecting plate, a first upper hinge seat, a first lower hinge seat and a shock-absorbing recovery member. Through the above method, when the bridge pavement is displaced, the upper sealing plate of the utility model is displaced in the left and right directions. Due to the restoring force of the spring, the spring pulls the slide plate inward to reset, the slide plate pulls the upper connecting plate inward, and the upper connecting plate pulls the upper sealing plate inward to achieve auxiliary reset, thereby accelerating the reset of the shock-absorbing rubber bearing.

[0004] This type of shock-absorbing rubber bearing is equipped with a displacement detection component to monitor the displacement of the rubber bearing and the recovery speed of the rubber bearing. However, in an earthquake environment, especially when vertical forces are generated, the upper and lower sealing plates will directly apply the forces to the rubber, and only rely on the tension of the spring to limit the relative movement between the building and the rubber. Since the initial deformation of the spring is the smallest and the elastic force is the smallest, but the initial kinetic energy of the building moving away from the rubber is the largest, the spring is extremely easy to be stretched and cause damage to the rubber. Utility Model Content

[0005] In view of this, the utility model aims to provide an embedded limited lifting support to achieve the purpose of making the rubber seat less likely to be damaged.

[0006] In order to solve the above technical problems, the technical solution of the utility model is: an embedded limit-type liftable support, comprising a rubber seat, an upper flange plate, and a lower flange plate, the lower flange plate is fixedly connected to the lower surface of the rubber seat, the upper flange plate is fixedly connected to the upper surface of the rubber seat, and also comprises a male limit plate, a female limit plate, a limit bolt and an embedded plate, the upper flange plate is located inside the male limit plate, the embedded plate is fixed on the building, the female limit plate is connected between the embedded plate and the male limit plate, the female limit plate is provided with an upper limit hole, the male limit plate is provided with a lower limit hole, the limit bolt comprises a limit rod and a limit head, the limit rod is threadedly connected to the upper limit hole and the lower limit hole, the limit head is pressed against the side of the male limit plate facing away from the female limit plate, and the stacked thickness of the female limit plate and the male limit plate is greater than the thickness of the upper flange plate.

[0007] To implement the above technical solution, since the stacked thickness of the female limit plate and the male limit plate is greater than the thickness of the upper flange plate, and the rubber seat is located inside the upper flange plate, when the building is subjected to a vertical force, the building moves away from the rubber seat, so that the male limit plate and the female limit plate move synchronously with the building. As the building continues to move, the limit head collides with the upper flange plate. At this time, the kinetic energy of the building's movement is reduced, so that when the force is transmitted to the rubber seat, the rubber seat can hold the building with a smaller deformation amount, thereby avoiding damage to the rubber seat and having a better shock-absorbing effect.

[0008] As a preferred solution of the utility model, an anti-slip ring is sleeved on the limit rod, one side of the anti-slip ring is used to abut against the side of the upper flange plate facing the lower flange plate, and the other side abuts against the limit head.

[0009] By implementing the above technical solution, the anti-slip ring can increase the contact area with the upper flange plate, so that the force can be better transmitted to the upper flange plate.

[0010] As a preferred solution of the utility model, the embedded plate is fixedly connected to the limiting tube, a connecting bolt is arranged in the limiting tube, the connecting bolt includes a connecting rod and a connecting head, the connecting rod passes through the male limiting plate, the female limiting plate and is threadedly connected to the limiting tube, the connecting head is fixed on the connecting rod and pressed against the side of the male limiting plate facing away from the female limiting plate.

[0011] Implementing the above technical solution can improve the connection stability between the embedded plate, the male limit plate and the female limit plate.

[0012] As a preferred solution of the utility model, the rubber seat comprises laminated rubber, laminated steel plates and a lead core, a plurality of the laminated rubbers and laminated steel plates are arranged at intervals, and the lead core is arranged in the center of the laminated rubbers and the laminated steel plates.

[0013] By implementing the above technical solution, the rubber seat has better structural strength to adapt to the lateral force of earthquake.

[0014] As a preferred solution of the utility model, a positioning groove is provided on the inner wall of the upper limit hole, the limiting bolt has a mounting hole along its length direction, a positioning rod is threadedly connected to the mounting hole, a sliding hole connected to the mounting hole is provided on the limiting rod, a positioning block is slidably connected to the sliding hole, the positioning rod moves toward the direction close to the limiting rod and the positioning block is partially embedded in the positioning groove through a conduction component.

[0015] To implement the above technical solution, the limit bolt is threadedly connected to the upper limit hole, and then the positioning rod is rotated. The positioning block is moved along the sliding hole through the conduction component, so that a part of the positioning block is located in the positioning groove, and the other part of the positioning block is located in the sliding hole, so that the limit bolt is not easy to fall out from the upper limit hole and the lower limit hole, thereby improving the structural stability.

[0016] As a preferred solution of the utility model, the conduction component includes a first bevel and a second bevel, the first bevel is opened at one end of the positioning block close to the mounting hole, the second bevel is opened at the end of the positioning rod, and the first bevel is used to interfere with the second bevel.

[0019] To implement the above technical solution, the support rod is passed through the connecting hole and then into the transverse hole, thereby limiting the rotation of the positioning rod and improving the placement stability of the positioning block. BRIEF DESCRIPTION OF THE DRAWINGS
