[0001] The invention relates to the technical field of construction engineering, and in particular to a steel structure earthquake-resistant buffer base for construction engineering. Background Art

[0002] With the acceleration of urbanization in my country, high-rise buildings and large steel structures have gradually become the mainstream of urban buildings. While providing spacious use space and modern appearance, these buildings also face severe earthquake resistance challenges. Earthquakes, as a sudden natural disaster, pose a serious threat to the safety and stability of buildings. Especially in earthquake-prone areas in my country, how to ensure the stability and safety of buildings during earthquakes and reduce the damage to building structures and the occurrence of secondary disasters caused by earthquakes have become important issues that need to be urgently solved in the field of construction engineering.

[0003] Among the existing building earthquake-resistant technologies, steel structures are widely used in the construction field due to their advantages such as light weight, high strength, and convenient construction. However, steel structure buildings also face a series of problems during earthquakes. The traditional earthquake-resistant buffering method is simple and has poor buffering effect, which can easily cause a large degree of deformation of the structure and even make the steel structure unable to be used normally.

[0004] To this end, the present application proposes a steel structure seismic buffer base for construction engineering. Summary of the invention

[0005] The purpose of the present invention is to solve the above technical problems and to propose a steel structure seismic buffer base for construction engineering.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: A seismic buffer base for a steel structure for construction engineering comprises a mounting seat, a support plate is provided above the mounting seat, two groups of buffer mechanisms for buffering the support plates are installed on the mounting seat, the buffer mechanism comprises two piston cylinders fixed on the mounting seat, a buffer piston is slidably connected in the piston cylinder, a buffer spring is fixedly connected to the bottom of the buffer piston, the lower end of the buffer spring is fixedly connected to the inner bottom of the piston cylinder, the upper end of the buffer piston is rotatably connected to a support rod, the upper end of the support rod is threadedly connected to the bottom of the support plate, a fixing column is fixed on the mounting seat, an inner cavity connected to the two piston cylinders is provided in the fixing column, and a damping piston capable of being reset is slidably connected in the inner cavity.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The buffer piston moves downward to squeeze the buffer spring, so that the buffer spring is compressed. The buffer piston can be buffered by the buffer spring, and then fed back to the support plate to buffer the support plate; the downward movement of the buffer piston can squeeze the hydraulic oil in the piston cylinder into the inner cavity through the delivery pipe. Since the cross-sectional area inside the delivery pipe is reduced, the delivery resistance of the hydraulic oil is increased, further improving the buffering effect on the support plate.

[0015] 2. The increase of hydraulic oil in the inner cavity will squeeze the damping piston, and the damping piston moves to squeeze the damping spring. The damping spring is compressed, thereby increasing the resistance to the movement of the damping piston and the resistance to the flow of hydraulic oil, which is then fed back to the buffer piston and the support plate, thereby providing an improved buffering effect on the support plate.

[0016] 3. The support plate moves downward, driving the limit block, the second positioning block, the second connecting rod and the connecting rod to move downward. At this time, the connecting rod and the sleeve rotate, the slider slides in the sleeve and squeezes the auxiliary spring, and the auxiliary spring is compressed, thereby producing a damping effect on the downward movement of the support plate.

[0017] 4. Due to different requirements for the support plate, such as different thicknesses, when a more suitable support plate is needed, the support plate needs to be disassembled and replaced. The staff pulls the pull block by hand, and the movement of the pull block drives the card rod to move, so that the card rod is separated from the card slot. At this time, the limit block is no longer limited. The limit block is taken out of the installation slot, and then the support rod is rotated to separate it from the support plate. The support plate can be removed for replacement. The operation is simple and convenient.

[0018] In summary, the present invention can provide multi-level and effective buffering for the support plate, thereby providing effective buffering protection for the steel structure, and the support plate can be easily disassembled and replaced, with simple and convenient operation.

[0025] It also includes four auxiliary buffer mechanisms, which include a first positioning block 16 fixed on the mounting seat 1, a first connecting rod 17 rotatably connected to the first positioning block 16, a sleeve 18 fixedly connected to the first connecting rod 17, a slider 32 slidably connected in the sleeve 18, an auxiliary spring 19 fixedly connected to the slider 32, the other end of the auxiliary spring 19 is fixedly connected to the inner wall of the sleeve 18, a connecting rod 20 fixedly connected to the slider 32, a second connecting rod 21 fixedly connected to the connecting rod 20, a second positioning block 22 rotatably connected to the second connecting rod 21, and the second positioning block 22 and the support plate 2 can be detachably connected.

[0026] The support plate 2 is provided with an installation groove 23, in which a limit block 24 is slidably connected, the limit block 24 is fixedly connected to the second positioning block 22, a clamping groove 25 is provided on the limit block 24, a slidably arranged clamping rod 28 is penetrated through the bottom of the support plate 2, the clamping rod 28 is slidably connected in the clamping groove 25, a U-shaped block 26 is fixedly connected to the bottom of the support plate 2, a slip ring 27 is slidably connected in the U-shaped block 26, the clamping rod 28 penetrates the slip ring 27 and is fixedly connected thereto, a return spring 29 is fixed on the slip ring 27, the other end of the return spring 29 is fixedly connected to the U-shaped block 26, the return spring 29 is sleeved on the outside of the clamping rod 28, the clamping rod 28 penetrates the U-shaped block 26 and is slidably connected thereto, and a pull block 30 is fixedly connected to the clamping rod 28.

The auxiliary spring 19 is compressed, thereby producing a damping effect on the downward movement of the support plate 2. Through the above, the support plate 2 can be effectively buffered, and then the steel structure can be effectively buffered and protected.

[0028] Due to different requirements for the support plate 2, such as different thicknesses, when a more suitable support plate 2 is needed, the support plate 2 needs to be disassembled and replaced. The staff manually pulls the pull block 30, and the movement of the pull block 30 drives the clamping rod 28 to move, so that the clamping rod 28 is separated from the clamping slot 25. At this time, the limit block 24 is no longer limited. The limit block 24 is taken out of the installation slot 23, and then the support rod 12 is rotated to separate it from the support plate 2. The support plate 2 can be removed for replacement. The operation is simple and convenient.
