Description

Technical Field

[0001] The utility model relates to the technical field of seismic isolation rubber bearings, in particular to a seismic isolation rubber bearing with wind resistance function. Background Art

[0002] Seismic isolation bearings refer to supporting devices that are installed in structures to meet seismic isolation requirements. Seismic isolation layers are added between the superstructure and the foundation, and rubber seismic isolation bearings are installed to provide a soft connection to the ground. Through this technology, about 80% of the energy of an earthquake can be offset. It is a structural member with small horizontal stiffness and large vertical stiffness. It can withstand large horizontal deformations and can be used as part of the load-bearing system.

[0003] When the seismic isolation bearing is in use, the protective rubber and internal steel plate directly exposed on the outside are easily corroded by wind and moisture. In order to prevent the rubber and internal steel plate from being exposed to wind and moisture for a long time, some seismic isolation bearings will add a protective cover on the outside. However, after long-term use, the protective cover is also easily weathered. Since the protective cover is looped on the bearing, it is inconvenient to replace it after weathering, which results in a shorter effective period of the wind resistance of the rubber bearing and easily affects the service life of the seismic isolation bearing. For this reason, we propose a seismic isolation rubber bearing with wind resistance function. Utility Model Content

[0021] The windproof component 6 includes an outer protective cover 61, an outer screw plate 62 and a fixed screw tube 63. The outer protective cover 61 is symmetrically sleeved on the outer side of the internal steel plate 2 and the protective rubber 3. Each outer protective cover 61 is fixed with an outer screw plate 62 on the upper and lower sides. The outer sides of every two outer screw plates 62 on the upper and lower sides are threaded with a fixed screw tube 63, and the outer ends of the fixed screw tubes 63 are fixed on the side of the connecting steel plate 5.

[0022] In this embodiment, the steel sealing plate 4 and the connecting steel plate 5 are fixed by a plurality of bolts, a plurality of threaded grooves cooperating with the bolts are provided inside the steel sealing plate 4 and the connecting steel plate 5, and a plurality of fixing holes are provided at the corners of the two connecting steel plates 5.

[0023] In this embodiment, the windproof component 6 also includes a fixing belt 64 and a fixed inner seam 65. The two side ends of the outer protective cover 61 on one side are fixed with fixing belts 64, and the two side ends of the outer protective cover 61 on the other side are provided with fixed inner seams 65 that cooperate with the fixing belts 64. Both sides of each fixing belt 64 are fixed to the inner wall of the fixed inner seam 65 by Velcro. The connection between the two outer protective covers 61 is sealed by the fixing belt 64 and the fixed inner seam 65, thereby ensuring the windproof protection effect of the outer protective cover 61.

[0024] In this embodiment, positioning plates 66 are fixed on the outer screw plates 62 at the upper and lower ends of the fixed inner seam 65, and limiting slots for inserting the positioning plates 66 are opened on the outer screw plates 62 at the upper and lower ends of the fixing belt 64. The outer protective cover 61 is made of a flexible anti-corrosion material, and is limited by the positioning plates 66 and the limiting slots, so that the two outer screw plates 62 can be aligned and then screwed into the inside of the fixed screw tube 63.

[0025] In this embodiment, the limiting assembly 7 includes a reinforcing card plate 71, a positioning groove 72 and a limiting groove 73. A plurality of reinforcing card plates 71 are fixed at equal intervals on the side wall of the connecting steel plate 5 on the outside of each steel sealing plate 4.

[0026] In the present embodiment, each reinforcement card plate 71 is configured to be "L"-shaped, and each reinforcement card plate 71, positioning groove 72 and limiting groove 73 are configured to be an arc shape that matches the steel sealing plate 4. The arc length of each positioning groove 72 is greater than the arc length of the reinforcement card plate 71, and the arc length of each positioning groove 72 is equal to half of the arc length of the limiting groove 73, thereby ensuring that the reinforcement card plate 71 can pass through the positioning groove 72 and rotate to engage in the limiting groove 73, thereby limiting the steel sealing plate 4 and the connecting steel plate 5.

The outer ring diameter of the reinforcing clamp plate 71 and the filling steel plate 74 is equal to the inner ring diameter of the outer screw plate 62. The reinforcing clamp plate 71 is further limited by the filling steel plate 74, thereby further increasing the firmness of the connection between the steel sealing plate 4 and the connecting steel plate 5.

[0028] Working principle: when it is necessary to assemble the seismic isolation bearing, align the reinforcement card plate 71 on the connecting steel plate 5 with the positioning groove 72, and insert it after alignment so that the connecting steel plate 5 fits with the steel sealing plate 4. After fitting, rotate it so that the reinforcement card plate 71 is engaged with the limiting groove 73. The connecting steel plate 5 can be limited by the cooperation of the reinforcement card plate 71 and the limiting groove 73. At this time, the threaded holes inside the steel sealing plate 4 and the connecting steel plate 5 are aligned, and the bolts are screwed into the threaded holes to fix them. Then, the filling steel plates 74 are inserted into the fixing screw tubes 63 one by one, and are adjusted to be aligned with the positioning groove 72 and then inserted so that the filling steel plates 74 are aligned and fit with the steel sealing plate 4 to achieve alignment. After the steel sealing plate 4 is filled, the side ends of the two outer protective sleeves 61 are aligned so that the fixing belt 64 is inserted into the fixed inner seam 65 and pressed so that the fixing belt 64 and the fixed inner seam 65 are fixed by Velcro. At the same time, the upper and lower outer screw plates 62 are aligned so that the positioning card plate 66 is inserted into the limiting card slot. After the two positioning card plates 66 at each end are aligned, they are directly screwed into the fixed screw tube 63 and fixed. The two outer protective sleeves 61 can be put on the outside of the internal steel plate 2 and the protective rubber 3 to facilitate alignment for protection. At this time, the filling steel plate 74 is limited by the outer screw plate 62 so that the filling steel plate 74 can be stably engaged in the positioning groove 72.
