Description

Technical Field

[0001] This utility model relates to the field of vibration damping base technology, specifically a vibration damping base for building steel structures. Background Technology

[0002] Steel structure supports are important components that connect steel structures to foundations or other structures. Their main advantage is that they transfer the load of the steel structure to the foundation or other supporting structures, ensuring the stability and safety of the structure.

[0003] A search revealed that the announcement number is CN213143407U, and the name is a steel structure seismic isolation bearing, including a base plate and a buffer mechanism. Through research and analysis, it was found that although the device provides buffering and prevents the greenhouse frame from shaking due to strong winds blowing on the greenhouse surface, it still has the following drawbacks to a certain extent.

[0004] For example, if the buffer mechanism is set vertically, it can only buffer vibrations in the vertical direction of the device. It is inconvenient to buffer when the building is subjected to side impacts and vibrations, which can easily lead to damage to the building from the side. In addition, the base plate and the top plate are only connected by the buffer component, which results in a large load on the buffer component and easy damage. This will reduce the stability of the building support. In order to solve the above technical problems, we designed a vibration damping base for building steel structure. Utility Model Content

[0005] The purpose of this utility model is to provide a shock-absorbing base for building steel structures, which has the advantages of good buffering performance and stable support. It solves the problems of inconvenience in buffering when a building is subjected to side impacts and vibrations, which easily leads to damage to the building from the side. In addition, the base plate and the top plate are only connected by a buffer component, which results in a large load on the buffer component and easy damage.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vibration damping base for a building steel structure, comprising a mounting base plate, a protective barrier fixedly welded to the top of the mounting base plate, a fixing component fixedly installed at the center of the bottom of the mounting base plate, the fixing component comprising a fixing base, the fixing base being fixedly installed at the center of the top of the mounting base plate, a reserved groove being formed around the inner wall of the fixing base, a cross groove being formed at the center of the bottom of the fixing base, a fixing plate being fixedly welded to the bottom of the outer ring of the fixing base, a fixing bolt being installed through the top of the fixing plate, and a main buffer assembly being installed inside the fixing base. The main buffer assembly includes a buffer rubber disposed within the inner cavity of a fixed base. A reinforcing steel plate is embedded inside the buffer rubber. A top steel plate is fixedly installed on the top of the buffer rubber, and a bottom steel plate is fixedly installed on the bottom of the buffer rubber. A damping column is provided through the top of the top steel plate. A support plate is fixedly connected to the bottom of the outer surface of the buffer rubber. Damping springs are fixedly connected to both sides of the support plate. The side of the damping spring away from the support plate is fixedly connected to the inner wall of a pre-reserved groove. A side buffer assembly is fixedly installed on the outer ring of the fixed base, and a mounting top plate is fixedly installed on the top of the top steel plate.

[0007] Preferably, the bottom of the fixing bolt passes through the fixing plate and is threaded to the top of the mounting base plate, and anchor rods are installed through the four corners of the top of the mounting base plate, with the bottom of the anchor rods extending to the bottom of the mounting base plate.

[0008] Preferably, the bottom of the damping column is sequentially connected to a top steel plate, a buffer rubber, a bottom steel plate, and a fixed base, and a cross plate is fixedly welded thereon, the cross plate being located in the inner cavity of the cross groove.

[0009] Preferably, the number of side buffer components is four, and they are evenly distributed on the outer surface of the fixed base. Each side buffer component includes a connecting plate, which is fixedly welded to the inner wall of the protective enclosure.

[0010] Preferably, a damping arc plate is fixedly connected to the other end of the connecting plate, and a fastening bolt is provided through the inner side of the damping arc plate.

[0011] Preferably, a fixing support plate is fixedly welded to the outer surface of the mounting top plate, and the fixing support plate is fixedly welded to the top of the protective fence.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention uses a fixed base to fix the main buffer assembly. A support plate is installed outside the buffer rubber, and damping springs are added on both sides of the support plate. When the building is impacted from the side, the buffer rubber causes the support plate to rotate, causing the damping springs on both sides to stretch and compress respectively, effectively buffering the side impact. In conjunction with the side buffer assembly, the protective fence is connected to the fixed base, so that there is a buffering force between the two. It can ensure that the shock-absorbing arc plate can absorb the vibration when it is subjected to vibration, effectively improving the buffering performance. The main buffer assembly and the fixed support plate support the building at the same time, so that the device is evenly stressed and the main buffer assembly is not overloaded, effectively ensuring the service life of the device. At the same time, it can improve the stability of the device support and prevent the device from shaking. Attached Figure Description

[0020] Please see Figures 1-5A shock-absorbing base for a building steel structure includes a mounting base plate 1. A protective barrier 2 is fixedly welded to the top of the mounting base plate 1. A fixing component 7 is fixedly installed at the center of the bottom of the mounting base plate 1. The fixing component 7 includes a fixing base 71, which is fixedly installed at the center of the top of the mounting base plate 1. A reserved groove 74 is provided around the inner wall of the fixing base 71. By providing the reserved groove 74, installation space can be provided for a support plate 87 and a damping spring 88. The damping spring 88 causes the support plate 87 and the buffer rubber 81 to have a rotational tendency, which can buffer the impact by rotation. A cross groove 75 is provided at the center of the bottom of the fixing base 71. A fixing plate 72 is fixedly welded to the bottom of the outer ring of the fixing base 71. A fixing bolt 73 is installed through the top of the fixing plate 72. A main buffer assembly is installed inside the fixing base 71. Component 8, the main buffer assembly 8 includes a buffer rubber 81, which is disposed in the inner cavity of the fixed base 71. A reinforcing steel plate 84 is embedded inside the buffer rubber 81. A top steel plate 82 is fixedly installed on the top of the buffer rubber 81, and a bottom steel plate 85 is fixedly installed on the bottom of the buffer rubber 81. A damping column 83 is provided through the top of the top steel plate 82. By setting the damping column 83, the buffer rubber 81 can be damped and limited during buffering, effectively ensuring that the buffer rubber 81 will not deform. A support plate 87 is fixedly connected to the bottom of the outer surface of the buffer rubber 81. A damping spring 88 is fixedly connected to both sides of the support plate 87. The side of the damping spring 88 away from the support plate 87 is fixedly connected to the inner wall of the reserved groove 74. A side buffer assembly 3 is fixedly installed on the outer ring of the fixed base 71, and a mounting top plate 6 is fixedly installed on the top of the top steel plate 82.

[0021] Please see Figure 1 , Figure 2 and Figure 3 The bottom of the fixing bolt 73 passes through the fixing plate 72 and is threaded to the top of the mounting base plate 1. Anchor rods 4 are installed through the four corners of the top of the mounting base plate 1. By setting the anchor rods 4, the mounting base plate 1 can be easily fixed in the required installation position to ensure that the mounting base plate 1 will not shake. The bottom of the anchor rod 4 passes through to the bottom of the mounting base plate 1.

[0022] Please see Figure 3 and Figure 4 The bottom of the damping column 83 passes through the top steel plate 82, the buffer rubber 81, the bottom steel plate 85 and the fixed base 71 in sequence, and a cross plate 86 is fixedly welded thereon. The cross plate 86 is located in the inner cavity of the cross groove 75. By setting the cross groove 75 and the cross plate 86, the damping column 83 can be limited, so that the damping column 83 can be fixed on the surface of the fixed base 71.

[0023] Please see Figure 1There are four side buffer components 3, which are evenly distributed on the outer surface of the fixed base 71. The side buffer component 3 includes a connecting plate 31, which is fixedly welded to the inner wall of the protective enclosure 2.

[0024] Please see Figure 1 The other end of the connecting plate 31 is fixedly connected to the shock-absorbing arc plate 32. The inner side of the shock-absorbing arc plate 32 is provided with a fastening bolt 33. The side buffer assembly 3 and the fixed plate 72 are staggered. The threaded end of the fastening bolt 33 passes through the shock-absorbing arc plate 32 and is threadedly connected to the outer surface of the fixed base 71. By setting the fastening bolt 33, the shock-absorbing arc plate 32 and the fixed base 71 are connected, so that when the fixed base 71 moves, it can drive the shock-absorbing arc plate 32 to deform for buffering, thereby improving the buffering performance. The bottom of the fixed base 71 is fixed to the mounting base plate 1 by welding.

[0025] Please see Figure 1 A fixed support plate 5 is fixedly welded to the outer surface of the top plate 6, and the fixed support plate 5 is fixedly welded to the top of the protective fence 2.

[0026] In use, the device is fixed to the installation position by anchor rods 4 and supported by the mounting base plate 1. The building is installed on top of the mounting top plate 6, and the main buffer component 8 is fixed by the fixed base 71. A support plate 87 is set outside the buffer rubber 81, and damping springs 88 are added on both sides of the support plate 87. When the building is impacted from the side, the buffer rubber 81 drives the support plate 87 to rotate, causing the damping springs 88 on both sides to stretch and compress respectively, effectively buffering the side impact. The protective enclosure 2 is connected to the fixed base 71 in conjunction with the side buffer component 3, so that there is a buffering force between the two. It can ensure that the shock absorption arc plate 32 can absorb the vibration when it is subjected to vibration, effectively improving the buffering performance. The main buffer component 8 and the fixed support plate 5 support the building at the same time, so that the device is evenly stressed and the main buffer component 8 is not overloaded. When subjected to vertical impact, the buffer rubber 81 provides buffer protection, effectively ensuring the service life of the device, and improving the stability of the device support, so that the device will not shake.

[0027] In summary, the vibration damping base of this building steel structure, through the cooperation of the base plate 1, protective enclosure 2, side buffer assembly 3, fixed support plate 5, top plate 6, fixing assembly 7, and main buffer assembly 8, solves the problems of inconvenient buffering when the building is subjected to side impacts and vibrations, which easily leads to damage to the building from the side. Furthermore, the base plate and the top plate are only connected by the buffer assembly, resulting in a large load on the buffer assembly and easy damage.
