[0002] In order to improve seismic performance, seismic isolation bearings are generally required in building structures. Existing seismic isolation bearings achieve the seismic isolation effect through laminated steel plates and rubber. However, existing seismic isolation bearings can only withstand pressure and horizontal displacement. For tall buildings, overturning moments may occur under strong winds and earthquakes, and existing seismic isolation bearings cannot withstand tensile forces. They may be damaged during use and cannot guarantee the safety of the building. Utility Model Content

The tensile mechanism includes two guide rails, a crossbar, and a tie rod. The two guide rails are parallel to each other and are disposed on the lower surface of the upper cover plate. The two ends of the crossbar are respectively located in the two guide rails and slidably connected to the guide rails. The upper end of the tie rod is rotatably and slidably connected to the crossbar, and the lower end of the tie rod is universally connected to the lower cover plate.

Detailed Implementation
[0018] The specific embodiments of this utility model will now be described with reference to the accompanying drawings.
[0019] like Figure 1 , Figure 2 As shown, this utility model is a tensile isolation bearing, the structure of which includes a lower cover plate 1, an upper cover plate 2, a laminated steel plate and rubber 3, and a tensile mechanism 4.
[0020] The tensile mechanism 4 is located between the lower cover plate 1 and the upper cover plate 2 of the support. It bears the pressure and horizontal displacement through the laminated steel plate rubber 3, and bears the overturning moment through the tensile mechanism 4. At the same time, it is necessary to ensure that the tensile mechanism 4 does not affect the normal function of the laminated steel plate rubber 3.
[0021] The tensile mechanism 4 of this utility model specifically includes two guide rails 4-1, a crossbar 4-2, and a pull rod 4-3.
[0022] Two guide rails 4-1 are located on the lower surface of the upper cover plate 2 of the support, and the two guide rails 4-1 are parallel to each other. The distance between the two guide rails 4-1 is the same as the length of the crossbar 4-2. The crossbar 4-2 is in a horizontal state, and its two ends are located in the two guide rails 4-1 respectively. The ends of the crossbar 4-2 are slidably connected to the guide rails 4-1, so that the crossbar 4-2 can move horizontally along the guide rails 4-1.
[0023] The crossbar 4-2 is connected to the lower cover plate 1 of the support via a tie rod 4-3. The upper end of the tie rod 4-3 is rotatably connected to the crossbar 4-2, while the lower end of the tie rod 4-3 is universally connected to the lower cover plate 1 of the support. The tie rod 4-3 and the crossbar 4-2 can rotate and slide relative to each other, and the tie rod 4-3 and the lower cover plate 1 of the support can swing relative to each other in any direction.
[0024] When the seismic isolation bearing is subjected to downward pressure, the distance between the lower cover plate 1 and the upper cover plate 2 of the bearing decreases. At this time, the crossbar 4-2 moves a certain distance along the guide rail 4-1, causing the tie rod 4-3 to tilt at a corresponding angle, thereby adapting to the reduction in the distance between the lower cover plate 1 and the upper cover plate 2 of the bearing, preventing damage to the tie rod 4-3, and ensuring the normal function of the laminated steel plate rubber 3.
[0025] When the upper cover plate 2 of the seismic isolation bearing undergoes horizontal displacement relative to the lower cover plate 1, the crossbar 4-2 moves along the guide rail 4-1, the end of the tie rod 4-3 moves along the crossbar 4-2, or both are combined, so that the tie rod 4-3 remains vertical, preventing damage to the tie rod 4-3 and ensuring the normal function of the laminated steel plate rubber 3.
[0026] When the upper cover plate 2 of the seismic isolation bearing is subjected to an upward tensile force, the tension is borne by the tie rod 4-3 to prevent damage to the laminated steel plate rubber 3.
[0027] The lower end of the pull rod 4-3 is provided with a fisheye connector 4-7, and a connecting ear plate 4-9 is provided on the upper surface of the lower cover plate 1 of the support. The fisheye connector 4-7 and the connecting ear plate 4-9 are connected by a pin 4-8. The fisheye connector 4-7 and the connecting ear plate 4-9 allow the pull rod 4-3 to swing in any direction around its lower end.
[0028] A bearing connector 4-5 is provided at the upper end of the tie rod 4-3. The crossbar 4-2 passes through the bearing connector 4-5. The bearing connector can move along the crossbar 4-2, and the bearing connector 4-5 can rotate around the crossbar 4-2.
[0029] Tie rod 4-3 is an adjustable tie rod 4-3. The specific length of tie rod 4-3 can be adjusted by the adjustment structure on tie rod 4-3, so as to adapt to the actual distance between the lower cover plate 1 and the upper cover plate 2 of the support in the installation state.
[0030] A limiting groove 4-6 is formed on the inner side of the guide rail 4-1. End bearings 4-4 are respectively installed at both ends of the crossbar 4-2, located within the limiting groove 4-6, enabling a movable connection between the crossbar 4-2 and the guide rail 4-1, and reducing friction through the bearings. Baffles are provided at both ends of the limiting groove 4-6 to prevent the end bearings 4-4 from dislodging from the ends of the limiting groove 4-6.
[0031] To facilitate the installation of the end bearing 4-4 in the limiting groove 4-6, bearing mounting ports 4-10 for installing the end bearing 4-4 are respectively provided on the two limiting grooves 4-6. The bearing mounting ports 4-10 on the two limiting grooves 4-6 are staggered to ensure that both end bearings 4-4 can be installed in the corresponding limiting grooves 4-6, while preventing the end bearing 4-4 from coming off the bearing mounting ports 4-10 of the limiting grooves 4-6 during use.
[0032] like Figure 4 As shown, the bearing mounting port 4-10 is an arc-shaped groove on the lower inner edge of the limiting groove 4-6. The distance from the bottom of the arc-shaped groove to the top of the limiting groove 4-6 is slightly larger than the diameter of the end bearing 4-4. The end bearing 4-4 can just pass through this arc-shaped groove and enter the limiting groove 4-6. After the end bearing 4-4 enters the limiting groove 4-6, it is prevented from coming out by the limiting action of the lower inner edge of the limiting groove 4-6. When it is necessary to remove the end bearing 4-4, move the end bearing 4-4 to the bearing mounting port 4-10, lift the end bearing 4-4 upward, and then remove the end bearing 4-4 from the bearing mounting port 4-10.
[0033] One of the guide rails 4-1 has a crossbar mounting port 4-11 for mounting the crossbar 4-2. The crossbar mounting port 4-11 is a round hole structure on the outer side of the guide rail 4-1. The crossbar 4-2 passes through the crossbar mounting port 4-11 into the limiting groove 4-6, and then passes through the end bearing 4-4, the bearing joint 4-5 in the limiting groove 4-6 on one side, and the end bearing 4-4 in the limiting groove 4-6 on the other side in sequence, thereby completing the installation of the crossbar 4-2.
[0034] Among them, there are at least two tensile mechanisms 4, and the tensile mechanisms 4 are evenly distributed around the laminated steel plate rubber 3.
[0035] like Figure 2As shown, in one embodiment of this utility model, there are four tensile mechanisms 4, which are evenly distributed around the laminated steel plate rubber 3, and the length direction of the crossbar 4-2 is consistent with the radius direction of the circular laminated steel plate rubber 3.
[0036] like Figure 3 As shown, in another embodiment of this utility model, there are two tensile mechanisms 4, which are symmetrically arranged on both sides of the laminated steel plate rubber 3. The length direction of the crossbar 4-2 is consistent with the radius direction of the circular laminated steel plate rubber 3.
[0037] This utility model's tensile isolation bearing, by adding a tensile mechanism 4, endows the isolation bearing with tensile strength, enabling it to withstand the overturning moment of the building, thereby preventing damage to the isolation bearing and ensuring the safety of the building structure during strong winds and earthquakes. Furthermore, the tie rod 4-3 only bears tensile force; under pressure and horizontal displacement, the tie rod 4-3 can adjust its angle to adapt, thus avoiding damage and failure under pressure and horizontal displacement, ensuring the stability and safety of this utility model.
