Description

Technical Field

[0001] The utility model relates to the technical field of rubber bearings, in particular to an anti-pullout rubber bearing. Background Art

[0002] Rubber bearings refer to supporting components used to support the weight of containers or equipment and fix them in a certain position. They also have to withstand vibration and seismic loads during operation. Plate rubber bearings are a type of bridge bearing product that is inlaid, bonded, and vulcanized with multiple layers of natural rubber and at least two layers of thin steel plates of the same thickness.

[0003] Since the interior of the rubber bearing is connected by laminated rubber and stiffening steel plates, the vertical tensile capacity of the rubber bearing is weak. If high-rise building structures use rubber bearings, when subjected to vertical earthquakes or large horizontal shear deformations, the rubber bearings are susceptible to vertical tensile forces. The weak bonding force between the rubber layer and the stiffening steel plate cannot resist the vertical tensile forces, causing the rubber bearings to be damaged, thereby causing the building structure to overturn and collapse. In view of this, we propose a pull-out rubber bearing. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet actual needs, and provide a pull-out resistant rubber bearing to solve the technical problem that when the current rubber bearing is subjected to vertical earthquake action or a large horizontal shear deformation occurs, the rubber bearing is susceptible to vertical tension, and the weak adhesion between the rubber layer and the stiffening steel plate cannot resist the vertical tension, resulting in damage to the rubber bearing, thereby causing the building structure to overturn and collapse.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing an anti-pullout rubber bearing, including a rubber bearing body, two sets of limit mechanisms are annularly symmetrically arranged on the outer side of the rubber bearing body, and an anti-pull structure is arranged on the outer side of the limit mechanism;

[0006] The tensile structure comprises a bending frame, which is arranged on the surface of the limiting mechanism, an inclined plate is fixedly arranged on the inner side of the bending frame, a shape memory alloy clamping plate is fixedly connected to the top end surface of the bending frame, and a clamping groove is attached to the outer side of the shape memory alloy clamping plate.

[0007] Preferably, the horizontal portion at the bottom end of the bending frame, the side inclined portion and the inclined plate together form a triangular structure, and the inclined plate is matched and fixed to the inner side of the bending frame.

[0008] Preferably, the shape memory alloy clamping plate is in a regular wave shape, and the shape memory alloy clamping plate is matched and engaged with the clamping slot.

[0009] Preferably, the limiting mechanism includes limiting plates, a group of the limiting plates are symmetrically fixed on the outside of the rubber support body, the upper limiting plate is externally sleeved with a limiting frame 1, the lower limiting plate is externally sleeved with a limiting frame 2, and the group of limiting plates are respectively connected to the limiting frame 1 and the limiting frame 2 by hexagonal bolts.

[0010] Preferably, both the first limiting frame and the second limiting frame are provided with limiting grooves matching the limiting plates.

[0011] Preferably, the first limiting frame and the slot are integrally formed, the bending frame forms a clamping structure with the slot via a shape memory alloy clamping plate, and the bending frame and the second limiting frame are fixedly connected.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model realizes the assembly between the tensile structure and the limiting mechanism by inserting the shape memory alloy card plate into the card slot. The triangular structure formed by the bottom horizontal part, the side inclined part and the inclined plate of the local bending frame can effectively increase the stability of the bending frame. At the same time, the regular wavy shape memory alloy card plate increases the contact surface with the card slot, so as to better disperse the force of the shape memory alloy card plate and improve the tensile and pull-out resistance of the shape memory alloy card plate.

[0014] 2. The utility model effectively fixes the limit frame 1 and the limit frame 2 to the outside of a group of limit plates through hexagonal bolts, thereby improving the convenience of disassembly and assembly. When the rubber bearing body is subjected to vertical tension or large horizontal shear deformation, the shape memory alloy clamping plate is subjected to force, thereby limiting the vertical tensile deformation and horizontal shear deformation of the rubber bearing body. The shape memory alloy clamping plate provides the rubber bearing body with good energy dissipation capacity and self-resetting ability. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The tensile structure 3 includes a bending frame 301, which is arranged on the surface of the limiting mechanism 2. An inclined plate 302 is fixed on the inner side of the bending frame 301, wherein the horizontal portion at the bottom end of the local bending frame 301, the side inclined portion and the inclined plate 302 together constitute a triangular structure, and the inclined plate 302 is matched and fixed on the inner side of the bending frame 301. A shape memory alloy clip 303 is fixed to the top end face of the bending frame 301, and a card slot 304 is attached to the outside of the shape memory alloy clip 303. Furthermore, the shape memory alloy clip 303 is regularly wavy, and the shape memory alloy clip 303 and the card slot 304 are matched and engaged. The utility model realizes the assembly between the tensile structure 3 and the limiting mechanism 2 by inserting the shape memory alloy clamping plate 303 into the clamping slot 304. The triangular structure formed by the bottom horizontal part, the side inclined part and the inclined plate 302 of the local bending frame 301 can effectively increase the stability of the bending frame 301. At the same time, the shape memory alloy clamping plate 303 with a regular wave shape increases the contact surface with the clamping slot 304, so as to better disperse the force of the shape memory alloy clamping plate 303 and improve the tensile and pull-out resistance of the shape memory alloy clamping plate 303.

[0024] It is worth noting that the limiting mechanism 2 includes a limiting plate 201, a group of limiting plates 201 are symmetrically fixed on the outside of the rubber support body 1, the upper limiting plate 201 is externally sleeved with a limiting frame 202, and the lower limiting plate 201 is externally sleeved with a limiting frame 203, wherein both the limiting frame 1 202 and the limiting frame 203 are internally provided with limiting grooves matching the limiting plate 201, further, the limiting frame 1 202 and the card slot 304 are integrally formed, the bending frame 301 forms a clamping structure with the card slot 304 through the shape memory alloy clamping plate 303, the bending frame 301 and the limiting frame 203 are fixedly connected, and a group of limiting plates 201 are respectively connected to the limiting frame 1 202 and the limiting frame 203 through hexagonal bolts 204. The utility model effectively fixes the limit frame 1 202 and the limit frame 203 to the outside of a group of limit plates 201 through the hexagonal bolts 204, thereby improving the convenience of disassembly and assembly. When the rubber bearing body 1 is subjected to vertical tension or large horizontal shear deformation, the shape memory alloy clamping plate 303 is subjected to force, thereby limiting the vertical tensile deformation and horizontal shear deformation of the rubber bearing body 1. The shape memory alloy clamping plate 303 provides the rubber bearing body 1 with good energy dissipation capacity and self-resetting ability.

The triangular structure composed of the bottom horizontal part, the lateral inclined part and the inclined plate 302 of the local bending frame 301 increases the stability of the bending frame 301. At the same time, the regular wavy shape memory alloy card plate 303 increases the contact surface with the card slot 304, which can better disperse the force of the shape memory alloy card plate 303 and improve the tensile and pull-out resistance of the shape memory alloy card plate 303. When the rubber bearing body 1 is subjected to vertical tension or large horizontal shear deformation, the shape memory alloy card plate 303 is subjected to force, thereby limiting the vertical tensile deformation and horizontal shear deformation of the rubber bearing body 1.
