Description

Technical Field

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

[0002] In recent years, base isolation has been gradually promoted and applied to high-rise and super-high-rise buildings, but the current common isolation rubber bearings have no wind resistance function and are very easy to displace under the action of wind loads, posing a danger to the safety of the upper structure. For isolation buildings in areas with large basic wind pressure, in order to meet the requirements of wind-resistant design, the usual design method is to increase the number of lead rubber bearings to increase the total yield shear force of the isolation layer to resist wind loads, but the arrangement cannot be too much, otherwise it will increase the horizontal stiffness of the isolation layer too much, affecting the horizontal isolation effect, and the method of increasing the wind resistance of the isolation layer by adding lead bearings will greatly increase the construction cost; most of the existing patents add wind-resistant bearings to the isolation rubber isolation layer to provide wind-resistant effects, but the existing wind-resistant bearings are generally designed with piers for installation separately, which will occupy part of the space in the isolation layer, increase the construction cost, and are not easy to replace.

[0024] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] For example, see Figure 1 , 2 3. The utility model provides a seismic isolation support with wind-resistant function, comprising a seismic isolation support, a wind-resistant component, and a connecting component.

[0026] Among them, the seismic isolation bearing includes a rubber seismic isolation part 1 and a flange plate 2 respectively arranged at both ends of the rubber seismic isolation part 1; the flange plate 2 is provided with a bearing mounting hole 3 and a wind-resistant part mounting hole 4, and the flange plate 2 is also provided with a limiting part 5; the wind-resistant component includes a mounting seat 6, a shear-resistant member 7 movably arranged in the mounting seat 6, and the mounting seat 6 is provided with a connecting hole 8 corresponding to the wind-resistant part mounting hole 4; both ends of the shear-resistant member 7 extend beyond the mounting seat 6 and are provided with a transition member 9, and the middle section of the shear-resistant member 7 is provided with a core section 10, and the end of the shear-resistant member 7 extending beyond the mounting seat 6 is detachably connected to the limiting part 5, so that the axis of the wind-resistant part mounting hole 4 coincides with the axis of the connecting hole 8; the connecting component includes a connecting member 11 that passes through the wind-resistant part mounting hole 4 and the connecting hole 8, and a locking member that cooperates with the connecting member 11; the connecting member 11 is stably connected to the locking member under the action of external force, thereby making the mounting seat 6 and the flange plate 2 stably connected.

[0027] For further information, see Figure 3 The limiting portion 5 includes a limiting groove 501, and the limiting groove 501 is located at the wind-resistant portion mounting hole 4.

[0028] Preferably, one end of the limiting groove 501 passes through the side edge of the flange plate 2 .

[0029] Preferably, two groups of flange plates 2 are provided, and both groups of flange plates 2 are provided with limiting grooves 501 with the same direction, and the positions of the limiting grooves 501 on the two groups of flange plates 2 are consistent.

[0030] In the above arrangement, the limiting groove 501 is used to connect with the end of the shear member 7 that extends beyond the mounting seat 6, to limit the position of the shear member 7, and further limit the position of the mounting seat 6, so that the axis of the wind-resistant mounting hole 4 coincides with the axis of the connecting hole 8.

[0031] For further information, see Figure 4 , 5 A through hole 12 is provided on the mounting seat 6, and the through hole 12 is located at the center of the mounting seat 6; the wind-resistant mounting hole 4 is located around the through hole 12; the shear-resistant member 7 includes a shear-resistant column 701, and the shear-resistant column 701 is movably installed in the through hole 12, and the shear-resistant column 701 and the through hole 12 are clearance-matched.

[0032] Preferably, the mounting seat 6 is in the shape of a truncated cone, a cube or other prism-shaped structure, and two groups of mounting seats 6 are arranged, and the top ends of the two groups of mounting seats 6 are arranged opposite to each other.

[0033] Preferably, see Figure 7 , 8 The shear column 701 is circular or square, and the through hole 12 corresponds to the shape of the shear column 701 is circular or square.

[0034] In the above arrangement, both ends of the shear column 701 respectively pass through the through hole 12 and extend beyond the bottom ends of the two sets of mounting seats 6. The bottom end of the mounting seat 6 is adjacent to the flange plate 2. The mounting column cooperates with the limiting groove 501 so that the axis of the wind-resistant mounting hole 4 and the connecting hole 8 coincide. The clearance between the shear column 701 and the through hole 12 is coordinated to facilitate the installation of the shear column 701 and to limit the shear column 701. After the mounting seat 6 is connected to the flange plate 2, the force is transmitted to the shear column 701 to cause shearing.

[0035] For further information, see Figure 6 The transition piece 9 includes a rubber pad 901 , and the rubber pad 901 is arranged at both ends of the shear column 701 .

[0036] Preferably, a blind hole is provided on the rubber pad 901, and both ends of the shear column 701 are located in the blind hole and are interference fit with the blind hole. The rubber pad 901 is firmly connected to the shear column 701 through the blind hole. After the wind-resistant assembly and the flange plate 2 are installed, the shear column 701 is prevented from being compressed to affect the shear performance.

[0037] For further information, see Figure 6 The core section 10 is a groove arranged in the middle of the shear column 701 , and the outer diameter of the groove is smaller than the outer diameter of the shear column 701 .

[0038] Preferably, the shape of the groove changes with the shape of the shear column 701. When the shear column 701 is cylindrical, the groove is circular; when the shear column 701 is square, the groove is arranged on both sides of the middle of the shear column 701 in a "V" shape.

[0039] Preferably, the connecting member 11 includes a connecting stud, and the locking member includes an internal thread arranged on the inner wall of the wind-resistant part mounting hole 4.

[0040] In the above arrangement, the mounting seat 6 and the flange plate 2 are stably connected by connecting the studs through the connecting holes 8 and the wind-resistant part mounting holes 4 and connecting with the internal threads.

[0041] In this embodiment, the limiting groove 501 cooperates with the shear column 701 so that the connecting hole 8 on the mounting seat 6 coincides with the axis of the wind-resistant mounting hole 4, which is convenient for installation, and the mounting seat 6 is stably connected to the flange plate 2 through the connecting studs; under the action of daily wind loads, the shear column 701 provides horizontal stiffness to resist the horizontal shear load generated by the wind load and provide shear resistance. The shear force increases under the action of moderate earthquakes and above, and the core section 10 on the shear column 701 is subjected to a shear force greater than its limit destruction and fails, and the seismic isolation support part begins to shear and consume energy.

[0042] After the shear column 701 fails due to shear shearing, loosen the connecting studs, slide the shear column 701 out along the limiting groove 501, replace the shear column 701, and after the replacement is completed, slide the shear column 701 from the limiting groove 501 and install it again. The connecting studs and the mounting seat 6 can continue to be used. The wind-resistant component is easy to replace, and only the failed shear column 701 needs to be replaced, which is economical and reliable.

[0043] The wind-resistant components can be installed according to the actual situation. They can be installed before the support is installed on the pier, or they can be installed after the support is installed.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
