Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, specifically to a seismic support for a large-span steel structure. Background Technology

[0002] Large-span steel structures are widely used in civil buildings such as theaters, stadiums, exhibition halls, assembly halls, airport waiting halls, and other large public buildings. The installation of large-span steel structures is highly mechanized, with high installation costs and high requirements for their seismic resistance.

[0003] Currently, Chinese patent CN221441799U discloses a seismic support for a steel structure support column, including a base. A connecting column is slidably connected to the inner side wall of the base. A first damping structure is provided on the outer side of the connecting column. The first damping structure includes a first elastic pad, a second elastic pad, and an arc-shaped block. The first elastic pad is disposed in the gap between the connecting column and the arc-shaped block. The inner side wall of the base is fixedly connected to the second elastic pad, and the second elastic pad and the connecting column are mutually compressed. The lower surface of the arc-shaped block is fixedly connected to the second damping structure. By using the arc shape of the arc-shaped block and the lower surface of the connecting column, the pressure generated in the vertical direction is effectively dispersed, and the horizontal vibration is absorbed and balanced under the action of the second elastic pad, effectively mitigating horizontal vibration.

[0004] The aforementioned steel structure support column seismic bearings have some problems in use. Although they can effectively disperse the pressure generated in the vertical direction and absorb and balance the horizontal vibration under the action of the second elastic pad, the large-span steel structure column itself bears a large load. Simply connecting it to the support column through the mounting hole may not be able to provide a sufficiently stable fixing effect. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-3This embodiment provides a seismic support for a large-span steel structure, including a support body 100 for the large-span steel structure, a placement plate 102 is provided on the top of the support body 100, a plurality of mounting holes 103 are provided on the surface of the placement plate 102, a plurality of fixing components for fixing the columns of the large-span steel structure are provided on the circumferential surface of the placement plate 102, and a damping component for damping the placement plate 102 is provided inside the support body 100.

[0024] The fixing assembly includes several sets of fixing clips 101 fixedly connected to the circumferential surface of the placement plate 102. A connecting post 105 is fixedly inserted into the surface of the fixing clip 101. A connecting plate 200 is rotatably sleeved on the surface of the connecting post 105. A pressure plate 201 is connected to the top of the connecting plate 200 through a fixing component. One end of the pressure plate 201 extends upward toward the placement plate 102. Rubber pads 208 are fixedly connected to the bottom of the end of the pressure plate 201 above the placement plate 102. A pushing component is provided at the bottom of the connecting plate 200 for pushing the connecting plate 200 outward, thereby driving the pressure plate 201 to press against the large-span steel structure column. Through the setting of the fixing assembly, the fixing clips 101, connecting posts 105, connecting plates 200 and pressure plates 201 cooperate with each other to press and fix the large-span steel structure column in multiple directions. At the same time, the connecting plate 200 can rotate around the connecting post 105, and the position of the pressure plate 201 can be adjusted by the pushing component, so as to adapt to support columns 104 of different sizes.

[0025] Furthermore, the pushing assembly includes a first bolt 202 threaded to the bottom of the outer side of the connecting plate 200. A fixing plate 108 is fixedly connected to the bottom of the placement plate 102 and to the corresponding position of the connecting plate 200. The first bolt 202 is threaded through the surface of the corresponding side connecting plate 200 and abuts against the surface of the fixing plate 108. By setting up the pushing assembly, rotating the bolt abuts against the fixing plate 108 to push the connecting plate 200. The pressing force of the pressure plate 201 on the support column 104 can be precisely controlled to ensure the fixing effect.

[0026] Furthermore, the fixing component includes a bearing 204 fixedly inserted into the top surface of the pressure plate 201. A second bolt 205 is fixedly inserted into the inner cavity of the bearing 204. One end of the second bolt 205 is threadedly connected to the top surface of the connecting plate 200 at the corresponding position. Guide components are provided on both sides of the top of the connecting plate 200 to guide the movement direction of the pressure plate 201. By setting the fixing component, rotating the second bolt 205 pushes the pressure plate 201 upward, thereby adjusting the distance between the pressure plate 201 and the placement plate 102 to adapt to the required thickness of the pressing column base plate.

[0027] Preferably, the guide includes fixing blocks 110 fixedly installed on the top of both sides of the connecting plate 200. The top surface of the fixing blocks 110 is fixedly connected with screws 203. The surface of the pressure plate 201 and the position corresponding to the screws 203 are provided with insertion holes 207. One end of the screw 203 passes through the insertion hole 207 at the corresponding position. Through the setting of the guide, the screws 203 in the guide are fixed on the fixing blocks 110 and pass through the insertion holes 207 of the pressure plate 201, which plays a precise guiding role when the pressure plate 201 moves, preventing the pressure plate 201 from deviating or shaking.

[0028] It is worth noting that one end of the screw 203 is threaded with a nut 206. The bottom of the nut 206 contacts the top surface of the pressure plate 201 at the corresponding position. By setting the nut 206, the nut 206 at one end of the screw 203 can further fix the position of the pressure plate 201, preventing the pressure plate 201 from loosening during use. In addition, the bottom of the nut 206 contacts the top surface of the pressure plate 201, increasing the pressure between the pressure plate 201 and the support column 104, and improving the firmness of the fixation.

[0029] Preferably, the shock-absorbing assembly includes a support column 104 fixedly connected to the bottom surface of the placement plate 102. A receiving groove 302 is provided inside the support body 100 at a position corresponding to the support column 104. A circular groove 303 corresponding to the support column 104 is provided on the bottom inner wall of the receiving groove 302. A polyurethane column 304 is disposed within the cavity of the circular groove 303. One end of the support column 104 passes through the top of the support body 100 and the cavity of the receiving groove 302, and is inserted into the cavity of the circular groove 303. One end of the support column 104 located within the cavity of the circular groove 303 contacts the top surface of the polyurethane column 304. A guide plate 300 is fixedly sleeved on the surface of the support column 104 located within the cavity of the receiving groove 302. A spring 301 is disposed within the cavity of the receiving groove 302, and both ends of the spring 301 contact the guide plate 300. The bottom of the plate 300 and the bottom inner wall of the receiving groove 302, and the top of the support body 100 are provided with several sets of circular grooves 109. The inner cavity of the circular grooves 109 is fixedly connected to a damper 107. The moving end of the damper 107 is fixedly connected to the bottom surface of the placement plate 102. Through the setting of the damping component, the polyurethane column 304 in the damping component has good elasticity and energy absorption characteristics, which can effectively absorb vibration energy and reduce the impact of vibration on the placement plate 102 and the support column 104. The combination of spring 301 and guide plate 300 can further slow down the movement of support column 104 and enhance the damping effect. At the same time, the damper 107 converts vibration energy into other forms of energy through internal damping mechanism, effectively reducing the duration and amplitude of vibration and improving the stability and safety of the entire structure.

[0030] Working principle;

[0031] First, the column of the large-span steel structure is placed on top of the placement plate 102. Then, the connecting bolt is inserted through the hole in the column base plate at the bottom of the column and into the mounting hole 103, and the nut 206 is tightened to initially install the column and the placement plate 102 together. Then, the first bolt 202 is rotated so that its end abuts against the fixing plate 108. As the first bolt 202 continues to rotate, the first bolt 202 pushes the connecting plate 200 outward, and the pressure plate 201 on its top moves upward toward the placement plate 102, gradually approaching the support column 104. Finally, the column base plate at the bottom of the support column 104 is pressed and fixed, thereby ensuring the fixing effect of the column.

[0032] When the column base plate is thick, and the distance between the pressure plate 201 and the placement plate 102 needs to be adjusted, loosen the nut 206 on the top of each pressure plate 201, then use a tool to turn the second bolt 205 to push the pressure plate 201 upward, thereby adjusting the distance between the pressure plate 201 and the placement plate 102 to adapt to the required thickness of the column base plate. Then tighten the nut 206 on the top of each pressure plate 201 to prevent the pressure plate 201 from coming off.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
