[0028] The utility model is described below with specific examples, but is not limited to the utility model.
[0029] Example one
[0030] As Figures 1-6 shown, in this embodiment, the anti-seismic support of large-span steel structure is provided, which comprises a base 1 and a top seat 2. The base 1 and the top seat 2 are both provided with mounting holes, and the mounting holes on the base 1 and the top seat 2 are used to be connected with other components of the steel structure through bolts and other connecting components to form a complete structural system.
[0031] The base 1 is provided with mounting holes. The top seat 2 is installed on the top of the base 1 and is inserted with the base 1, and the top seat 2 is provided with mounting holes. The mounting holes in the base 1 and the top seat 2 are connected through a screw rod 4. The base 1 and the top seat 2 are installed with a pad 3, which comprises a frame 301 and a cushion 302. The frame 301 and the cushion 302 are both double-layer structures and are arranged in cross. When bearing pressure, the frame 301 and the cushion 302 work cooperatively, and the cross structure is used to disperse the pressure. The mounting holes of the base 1 and the top seat 2 are convenient for connecting with other components of the steel structure to realize the installation and positioning of the anti-seismic support. The special structure design of the pad 3 enhances the buffering performance of the anti-seismic support, which can effectively disperse the stress generated by the large-span steel structure under the action of the earthquake and improve the stability and anti-seismic ability of the structure.
[0032] The material of the cushion 302 is rubber. When the base 1 and the top seat 2 are in a fixed state, the inner shaft 201 applies pressure to the rubber, and the rubber cushion 302 has good elasticity and energy absorption characteristics. When the base 1 and the top seat 2 are in a fixed state, the inner shaft 201 applies a certain pressure to the rubber cushion 302, so that the cushion 302 is in a pre-pressing state. When the earthquake occurs, the cushion 302 can more quickly and effectively absorb the vibration energy.
[0033] Example two
[0034] As Figures 1-6 shown, on the basis of example one, the buffering structure is provided in this embodiment, which is as follows:
[0035] The inner groove 102 is provided with an inner support column 101 on the outside, and the top base 2 is fixed with an inner shaft 201 which is inserted into the inner groove 102. When the top base 2 is stressed, the inner shaft 201 moves in the inner groove 102 of the base 1, and the inner support column 101 supports and reinforces the inner groove 102. This cooperation makes the connection between the top base 2 and the base 1 more stable and has a certain activity space. Under the action of seismic force, the inner shaft 201 can move within a certain range to adapt to the displacement deformation of the structure, and the inner support column 101 enhances the structural strength of the base 1 to prevent the inner groove 102 from being damaged due to excessive stress, thereby ensuring the normal work of the seismic support.
[0036] A gap is left between the inner support column 101 and the top base 2, so that when the top base 2 is displaced due to seismic force, it will not directly collide with the inner support column 101, reducing the risk of structural damage. The existence of the gap forms a flexible connection relationship between the top base 2 and the inner support column 101, which ensures the supporting effect of the inner support column 101 on the base 1 while allowing the top base 2 to move freely within a certain range.
[0037] The inner shaft 201 is fixed with an inner convex column 202, and a gap is left between the inner convex column 202 and the bottom of the inner groove 102. When the structure vibrates, the inner convex column 202 moves within the gap range driven by the inner shaft 201, which can buffer the vibration energy to a certain extent. The gap provides a moving space for the inner convex column 202, allowing the inner shaft 201 to move freely within a certain range, avoiding direct transmission of vibration energy due to rigid connection, and playing a buffering and energy dissipation role, which helps to reduce the vibration response of the large-span steel structure in the earthquake.
[0038] The number of the buffer pads 302 is multiple and they are distributed circumferentially in the inner groove 102. The inner groove 102 is provided with a plurality of buffer pads 302, and the inner convex column 202 is inserted into the insertion hole 303. When the structure vibrates, the inner convex column 202 extrudes the buffer pad 302, and the buffer pad 302 deforms to absorb vibration energy. Through the cooperation of the buffer pad 302 and the inner convex column 202, the buffering and damping capacity of the seismic support is further enhanced, and the multiple buffer pads 302 work together to absorb vibration energy from different directions, improving the stability of the large-span steel structure in the earthquake.
[0039] Embodiment three
[0040] As Figures 5-6On the basis of embodiment one and embodiment two, the embodiment provides the shape and installation of the buffer pad 302, as follows:
[0041] The buffer pad 302 is a fan shape, the tip of the buffer pad 302 is an arc-shaped opening, and multiple arc-shaped openings form a jack 303. When subjected to extrusion under vibration, the fan-shaped buffer pad 302 is more likely to elastically deform due to the special shape, and the design of the arc-shaped opening makes the contact between the buffer pads 302 more compact, and the cooperative work effect is better. This shape design optimizes the stress performance of the buffer pad 302, so that it can more effectively absorb vibration energy. At the same time, the compact contact mode enhances the stability of the buffer pad 302 as a whole, and improves the shock absorption effect of the seismic support.
[0042] The inner side of the frame 301 is provided with an embedded groove, and the buffer pad 302 is provided with a plug plate which can be inserted into the embedded groove. When installed, the plug plate is inserted into the embedded groove, so that the frame 301 and the buffer pad 302 are connected into a whole, and jointly bear the pressure and vibration energy. The stability of the connection between the frame 301 and the buffer pad 302 is ensured, and under complex stress conditions, the two will not displace relative to each other, ensuring the integrity of the pad plate 3 structure, so as to continuously and effectively play the buffering and shock absorption role.
[0043] Working principle:
[0044] The seismic support of the large-span steel structure is composed of a base 1 and a top seat 2. The base 1 and the top seat 2 are connected through a screw rod 4 via an internal mounting hole, and the top seat 2 and the base 1 are in a plug-in manner. The base 1 is internally provided with an inner groove 102, and the fixed inner shaft 201 of the top seat 2 can be inserted into the inner groove 102 to move. When an earthquake occurs, the structure is deformed, and the inner shaft 201 can move within a certain range of the inner groove 102 of the base 1 to adapt to the deformation. The inner support column 101 outside the inner groove 102 provides support and reinforcement for it to avoid damage due to excessive stress. The gap between the top seat 2 and the inner support column 101 prevents rigid collision when the top seat 2 displaces under the action of seismic force. The gap between the inner convex column 202 on the inner shaft 201 and the bottom of the inner groove 102 can buffer the vibration energy. The multiple fan-shaped buffer pads 302 distributed in the inner groove 102 have internal jacks 303 for the insertion of the inner convex column 202. When vibrating, the inner convex column 202 extrudes the buffer pad 302, and the buffer pad 302 absorbs vibration energy by using the good elasticity and energy absorption characteristics of rubber. The double-layer cross structure of the frame 301 and the buffer pad 302 further disperses the pressure, and realizes the seismic resistance and shock absorption.
[0045] Finally, it should be noted that the above examples are intended to illustrate and not limit the technical solutions of the present application. Although the present application has been described in detail with reference to the above examples, those skilled in the art should understand that the present application can still be modified or equivalently replaced without departing from the spirit and scope of the present application, and any modification or partial replacement thereof should be covered in the scope of the claims of the present application.
