Description

Technical Field

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

[0002] A rubber bearing is a key component used in bridge and building structures, mainly made of natural rubber or synthetic rubber. Its main function is to transfer the load of the structure to the foundation, while allowing a certain degree of horizontal displacement and rotation to absorb the deformation and vibration of the structure. Rubber bearings have good elasticity and durability, and can effectively extend the service life of bridges and buildings.

[0003] In the prior art, after the rubber bearing fixes the bridge, affected by seismic force or wind force, the rubber bearing is displaced due to the horizontal force, and thus is prone to overturning. In addition, after the bridge girder is installed on the rubber bearing, there may be a gap between the bottom surface of the girder and the bottom of the rubber bearing, so there may be an uneven force between the rubber bearing and the girder. For this reason, an anti-overturning structure for rubber bearings is proposed to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model can be achieved by the following technical solutions:

[0006] An anti-overturning structure for rubber bearings includes a rubber bearing main body, and limiting mechanisms are arranged on both sides of the rubber bearing main body;

A number of angular scales are arranged on the surface of the dial, and the angular scales on the surface of each dial are arranged equidistantly around the center of the rotating shaft.

[0013] As a further solution of the utility model: The rubber bearing body includes a lower bottom plate, a buffer part is fixedly installed in the middle of the top of the lower bottom plate, and an upper top plate is fixedly installed on the top of the buffer part.

[0014] As a further solution of the utility model: Slots are respectively opened in the middle of both sides of the lower bottom plate. Fixing holes one are opened above each slot on the top surface of the lower bottom plate. Positioning grooves are respectively opened on both sides of the top surface of the upper top plate, and fixing holes two are opened on the side of the upper top plate.

Then, it is convenient to select a suitable caulking plate to be installed between the rubber bearing and the girder, which helps to improve the uniform force between the rubber bearing and the bridge.

[0028] The inner wall of the top end of the abutting sleeve 206 is rotatably connected with a rotating plate 209. A rotating shaft 211 is fixedly connected to the side of the rotating plate 209. The end of the rotating shaft 211 penetrates through the surface of the abutting sleeve 206, and an indicating needle 212 is fixedly connected to one end of the rotating shaft 211 located outside the abutting sleeve 206. As Figures 1-2 shown, the rotating plate 209 rotates synchronously with the rotating shaft 211;

[0029] One end of the side wall of the abutting sleeve 206 is rotatably connected with a second spring 208. The other end of the second spring 208 is rotatably connected to the middle of the bottom surface of the rotating plate 209. A gasket 210 is fixedly connected to the top surface of the rotating plate 209. As Figure 1 shown, the gasket 210 is made of rubber to prevent the upper beam body from damaging the surface of the rotating plate 209;

[0030] A dial 213 is fixedly connected to the surface of the abutting sleeve 206 and located outside the rotating shaft 211. A number of angular scales are arranged on the surface of the dial 213, and the angular scales on the surface of each dial 213 are arranged equidistantly around the center of the rotating shaft 211. As Figure 2 shown, the pointing of the indicating needle 212 on the dial 213 can be used to judge the rotation angle of the rotating plate 209, and further determine the inclination angle of the bottom surface of the beam body;

[0031] The rubber bearing body 1 includes a lower bottom plate 101. A buffer part 102 is fixedly installed in the middle of the top of the lower bottom plate 101. An upper top plate 103 is fixedly installed on the top of the buffer part 102. Slots 104 are respectively opened in the middle of both sides of the lower bottom plate 101. Fixing holes one 105 are respectively opened on the top surface of the lower bottom plate 101 and above each slot 104. Positioning grooves 106 are respectively opened on both sides of the top surface of the upper top plate 103, and fixing holes two 107 are opened on the side of the upper top plate 103. A positioning block 109 is inserted into the inner side of the positioning groove 106. Fixing holes three 110 are opened on the surface of the positioning block 109 near the fixing hole two 107.

Thus, when the lower bottom plate 101 is subjected to a horizontal force, the connecting seat 201 can prevent the displacement of the lower bottom plate 101;

[0035] When the beam body is installed above the upper top plate 103, the beam body first falls above the two rotating plates 209. According to the inclination angle of the bottom surface of the beam body, the beam body presses the rotating plate 209 to rotate, so that the rotating shaft 211 drives the indicating needle 212 to slide on the surface of the indicating disc 213. After the rotating plate 209 is stable, select the caulking plate 108 that can fit the bottom surface of the beam body according to the scale indicated by the indicating needle 212 on the indicating disc 213, and insert the positioning block 109 at the bottom of the caulking plate 108 into the positioning groove 106. When fixing, insert and weld the metal connecting column from the second fixing hole 107 into the third fixing hole 110. Finally, rotate the nut 205 to make it descend along the column 204, so that the rotating plate 209 holds the upper beam body and gradually descends above the caulking plate 108, and then the rubber bearing body 1 bears the upper beam body.
