Description

Technical Field

[0001] The utility model relates to the technical field of bridge bearings, in particular to a bridge bearing for seismic protection. Background Art

[0002] A bridge bearing is an important structural component connecting the upper and lower structures of a bridge. It can reliably transfer the reaction force and deformation of the upper structure of the bridge to the lower structure of the bridge, so that the actual stress situation of the structure conforms to the calculated theoretical diagram. The main functions of the bridge bearing include transferring loads, alleviating vibrations and noises, adapting to deformations, facilitating construction and maintenance, and resisting natural disasters. During the use of the bridge, certain vibrations and noises will be generated, which not only affect the driving comfort, but may also cause damage to the bridge structure and the surrounding environment. The bridge bearing has good shock absorption and sound insulation effects, and can effectively alleviate the vibrations and noises generated during bridge driving, improving the driving comfort and safety. Due to natural factors and the load action during use, the bridge will undergo a certain degree of deformation. The bridge bearing has the ability to adapt to deformations, can effectively resist earthquakes, and maintain the stability and service life of the bridge. However, for the common bridge bearings for seismic protection on the market, during seismic resistance, they can only buffer vibrations up and down, and cannot buffer the lateral vibration force. Moreover, after the bearing is connected to the bridge through bolts, due to the continuous vibration of the bridge, the nuts are prone to loosen, posing a safety hazard. Summary of the Utility Model

[0003] An embodiment of the present disclosure relates to a bridge bearing for seismic protection. When the bottom bearing and the top bearing are used in cooperation, the insertion head structure is inserted into the groove of the contact component. When encountering vibrations, the insertion head structure presses down on the contact component, compresses the spring through the force-bearing component, and buffers the up-and-down vibration force by means of elasticity and the elasticity of the contact component. When a lateral vibration force is generated, the side of the insertion head structure squeezes the side wall of the contact component, so that the side wall of the contact component elastically eliminates the collision force. At the same time, the outer rod component is externally supported on the contact component to ensure the support strength.

[0004] In the first aspect of the present disclosure, a bridge bearing for seismic protection is provided, which specifically includes: a bottom bearing; a contact component is installed at the top end of the bottom bearing through a positioning component. A groove is provided at the top end of the contact component made of high-strength rubber material. The outer rod components arranged uniformly are embedded and fixed on the outside of the contact component, and the outer rod components are made of metal material; a top bearing; the top bearing is located at the top end of the bottom bearing. The top bearing is inserted with a metal plug plate structure through a connecting piece and a slot. A clamping plate structure is provided on each side of the plug plate structure, and the inner side of the outer end of the clamping plate structure is an arc structure. The plug plate structure and the clamping plate structure are both made of elastic metal material.

[0005] In at least some embodiments, four annularly arranged auxiliary grooves are formed at the top end of the bottom support, and a guide rod assembly is fixed to the top end of each auxiliary groove. A spring is sleeved outside each guide rod assembly; a positioning assembly with a circular ring structure is provided at the top end of the bottom support, and a force-bearing assembly is inserted into the positioning assembly. Through grooves are annularly and evenly arranged at the bottom of the outer end of the positioning assembly, and the through grooves are located inside the auxiliary grooves; the force-bearing assembly made of metal is embedded and fixed at the bottom of the contact assembly. The outer end of the force-bearing assembly with a circular ring structure is a rectangular structure, and the outer end of the force-bearing assembly is inserted into the through grooves and moves up and down. The guide rod assembly penetrates through the outer end of the force-bearing assembly, and the top end of the spring contacts the bottom of the outer end of the force-bearing assembly and continuously pushes the force-bearing assembly upward. A uniformly arranged positioning block is fixed inside the contact assembly.

[0006] In at least some embodiments, a connecting member is fixed to the bottom of the top support. The connecting member is an octagonal structure, and a slot is formed at the outer end of the connecting member. An insertion plate structure is inserted into the slot; an insertion head structure is fixed to the bottom of the connecting member, and the insertion head structure is inserted into the groove of the contact assembly. A uniformly arranged splicing groove is provided on the outside of the insertion head structure, and a positioning block is inserted into the splicing groove; connection holes are formed at the corner positions of the top support, and a connection bolt is inserted into the connection holes. A nut is provided outside the connection bolt. The connection bolt is fixed to the bottom of the bridge in advance, and the bottom of the connection bolt is inserted into the inner side of the clamping plate structure and is clamped with the clamping plate structure. The top ends of the insertion plate structure and the clamping plate structure contact the bottom of the nut and limit the movement of the nut. A pulling groove is formed through the inside of the insertion plate structure.

[0007] The present utility model provides a bridge bearing for seismic protection, which has the following beneficial effects:

[0008] When the bottom support and the top support are used in cooperation, the insertion head structure is inserted into the groove of the contact assembly. When encountering vibration, the insertion head structure presses down the contact assembly, compresses the spring through the force-bearing assembly, and buffers the up-and-down vibration force by means of elasticity and the elasticity of the contact assembly. When a lateral vibration force is generated, the side of the insertion head structure squeezes the side wall of the contact assembly, so that the side wall of the contact assembly elastically eliminates the collision force. At the same time, the outer rod assembly is outside the contact assembly for support to ensure the support strength.

[0009] After the top support is connected to the bridge through the connection bolt, the insertion plate structure can be controlled to be inserted and installed, so that the inner end of the insertion plate structure is inserted into the slot, and the insertion plate structure is positioned and installed. At the same time, the clamping plate structure is clamped with the connection bolt by means of elastic deformation to achieve positioning and fixing. After fixing, the top ends of the insertion plate structure and the clamping plate structure contact the bottom of the nut to limit the nut, so that the nut will not rotate and displace downward after encountering vibration, realizing the fixation of the nut.

After the bridge is installed, the connecting bolt 205 at the bottom of the bridge is inserted into the connecting hole of the top member support 2, and then the nut is controlled to be installed so that the top member support 2 is firmly connected to the bridge. Then, the insertion plate structure 206 is controlled to be inserted into the slot 202 so that the insertion plate structure 206 drives the clamping plate structure 207 to be installed and used together. The clamping plate structure 207 is elastically inclined and clamped with the connecting bolt 205. The tops of the insertion plate structure 206 and the clamping plate structure 207 are in contact with the bottom of the nut to limit and fix the nut, preventing the nut from loosening and displacing after encountering vibration. When the bottom support 1 and the top member support 2 are in use and encounter vibration, the plug head structure 203 can move left and right, up and down in the groove of the contact assembly 106. When moving up and down, while squeezing the contact assembly 106, the spring is squeezed to improve the shock absorption effect. When moving left and right horizontally, the side wall of the contact assembly 106 is squeezed to improve the shock absorption performance.
