A seismic damper between building frames

Abstract

This utility model discloses a seismic damper between building frames, including a first frame column, a crossbeam connected to the first frame column, and a second frame column connected to the other end of the crossbeam. This utility model increases the stability of the building by adding a seismic-resistant mechanism between the two frame columns. This mechanism consists of two support frames. Simultaneously, the serrations on the first and second serrated friction plates on the first and second support frames increase the friction between the two components. During an earthquake, the frames sway, ensuring both the space for movement and the stability between the frames. The components support each other, and the energy dissipation through friction damping improves the seismic performance of the frame. Workers can move the first serrated friction plate by rotating bolts, allowing adjustment of the gap between the two serrated friction plates. The contact pressure of the friction surfaces is controlled by the bolt preload.

Description

Technical Field

[0001] This utility model belongs to the field of seismic resistance technology in buildings, specifically relating to a seismic damper between building frames. Background Technology

[0002] A frame building is a structure composed of a frame, wall panels, and floor slabs. Its basic characteristics include load-bearing structures supported by columns, beams, and floor slabs, with wall panels serving only as enclosures and space dividers. The building frame, composed of beams and columns, is a rigidly connected structure capable of withstanding vertical and horizontal loads. It is primarily used as the load-bearing framework for industrial and civil buildings, bridge frames, or engineering structures. Generally, it refers to a structure in building construction consisting of beams or end frames connected to columns.

[0003] Currently, the support between existing building frames mainly relies on frame columns. However, the simple structure of frame columns leads to poor seismic resistance between building frames. Therefore, a seismic damper between building frames is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a seismic damper between building frames to address the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a seismic damper between building frames, including a first frame column, a crossbeam connected to the first frame column, a second frame column connected to the other end of the crossbeam, and a seismic mechanism provided between the first frame column and the second frame column.

[0006] The seismic-resistant mechanism includes a first support frame and a second support frame. A housing is connected to the first support frame. An adjusting block is provided inside the housing. A first serrated friction plate is connected to the bottom of the adjusting block. An internal threaded hole is provided on the housing. A bolt is threaded into the internal threaded hole. A limit groove is provided on the inner wall of the housing. A limit block is slidably connected inside the limit groove. The limit block is connected to the adjusting block. A second serrated friction plate is provided on the second support frame. The first serrated friction plate and the second serrated friction plate mesh with each other.

[0007] The present invention further explains that the first support frame is connected to the first frame column through a first hinge seat, and the second support frame is connected to the second frame column through a second hinge seat. The arrangement of the first support frame and the second support frame can improve the stability between the frames.

[0008] The present invention further explains that the lower end of the bolt abuts against the upper surface of the adjusting block, and a spring is sleeved on the bolt. By rotating the bolt, the position of the first serrated friction plate can be adjusted, so that the gap between the first serrated friction plate and the second serrated friction plate can be adjusted.

[0009] The present invention further explains that the lower end of the spring abuts against the upper surface of the housing, and the upper end of the spring abuts against the bolt. The spring is in a compressed state. The spring can prevent the bolt from loosening freely or vibrating when under force, thus playing the role of fixing and stabilizing the bolt.

[0010] The present invention further explains that there are two limiting grooves, which are respectively opened on the inner left wall and the inner right wall of the housing. The limiting grooves can limit the limiting block and prevent the limiting block from leaving the interior of the housing.

[0011] The present invention further explains that there are two limiting blocks, which are respectively connected to the left and right walls of the adjusting block. The limiting blocks can play a limiting and guiding role for the adjusting block, making the adjusting block more stable and preventing the adjusting block from detaching from the housing.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0013] (1) This utility model adds an anti-seismic mechanism between two frame columns. The anti-seismic mechanism consists of two support frames, which increases the stability of the building. At the same time, the first sawtooth friction plate on the first support frame and the sawtooth on the second sawtooth friction plate on the second support frame can increase the friction between the two components. When an earthquake occurs, the frames shake, which not only ensures the activity space between the frames, but also ensures the stability between the frames. The components support each other, and the energy dissipation through friction damping can improve the seismic performance of the frame.

[0014] (2) When it is necessary to adjust the gap between the first sawtooth friction plate and the second sawtooth friction plate, the operator can move the first sawtooth friction plate by rotating the bolt, so that the gap between the two sawtooth friction plates can be adjusted, and the contact pressure of the friction surface can be controlled by the bolt preload.

[0022] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0023] Please see Figure 1-5 The present invention provides a technical solution: a seismic damper between building frames, including a first frame column 1, a crossbeam 3 connected to the first frame column 1, a second frame column 4 connected to the other end of the crossbeam 3, and a seismic mechanism 2 provided between the first frame column 1 and the second frame column 4.

[0024] The seismic-resistant mechanism 2 includes a first support frame 201 and a second support frame 202. A housing 203 is connected to the first support frame 201. An adjusting block 207 is installed inside the housing 203, and a first serrated friction plate 208 is connected to the bottom of the adjusting block 207. An internally threaded hole 204 is provided on the housing 203, and a bolt 205 is threaded into the internal thread of the internally threaded hole 204. A limiting groove 209 is provided on the inner wall of the housing 203, and a limiting block 210 is slidably connected inside the limiting groove 209. The limiting block 210 is connected to the adjusting block 207. A second serrated friction plate 212 is provided on the second support frame 202. The first serrated friction plate 208 and the second serrated friction plate 212 mesh with each other. The first serrated friction plate 208 and the second serrated friction plate 212 are made of wear-resistant alloy. This mechanism, by adding seismic resistance between the two frame columns... Mechanism 2, its seismic-resistant mechanism 2 consists of two support frames, which increases the stability of the building. At the same time, by utilizing the serrations on the first serrated friction plate 208 on the first support frame 201 and the second serrated friction plate 212 on the second support frame 202, the friction between the two components can be increased. When an earthquake occurs, the frames shake, which not only ensures the movement space between the frames, but also ensures the stability between the frames. The components support each other, and the energy dissipation through friction damping can improve the seismic performance of the frame. When it is necessary to adjust the gap between the first serrated friction plate 208 and the second serrated friction plate 212, the staff can push the first serrated friction plate 208 to move by rotating the bolt 205, so that the gap between the two serrated friction plates can be adjusted. The contact pressure of the friction surface is controlled by the preload of the bolt 205.

[0025] The first support frame 201 is connected to the first frame column 1 via the first hinge seat 211, and the second support frame 202 is connected to the second frame column 4 via the second hinge seat 213. The arrangement of the first support frame 201 and the second support frame 202 can improve the stability between the frames.

[0026] The lower end of the bolt 205 abuts against the upper surface of the adjusting block 207. A spring 206 is fitted on the bolt 205. By rotating the bolt 205, the position of the first sawtooth friction plate 208 can be adjusted, so that the gap between the first sawtooth friction plate 208 and the second sawtooth friction plate 212 can be adjusted.

[0027] The lower end of the spring 206 abuts against the upper surface of the housing 203, and the upper end of the spring 206 abuts against the bolt 205. The spring 206 is in a compressed state. The spring 206 can prevent the bolt 205 from loosening freely or vibrating when under force, thus fixing and stabilizing the bolt 205.

[0028] There are two limiting grooves 209, which are respectively opened on the inner left wall and the inner right wall of the housing 203. The limiting grooves 209 can limit the limiting block 210 and prevent the limiting block 210 from leaving the interior of the housing 203.

[0029] There are two limit blocks 210, which are connected to the left and right walls of the adjusting block 207 respectively. The limit blocks 210 can limit and guide the adjusting block 207, making it more stable and preventing it from detaching from the housing 203.

[0030] By adding an anti-seismic mechanism 2 between the two frame columns, which consists of two support frames, the stability of the building is increased. At the same time, the sawtooth-shaped friction plate 208 on the first support frame 201 and the sawtooth-shaped friction plate 212 on the second support frame 202 increase the friction between the two components. When an earthquake occurs, the frames shake, ensuring both the movement space between the frames and the stability between the frames. The components support each other, and the energy dissipation through friction damping can improve the seismic performance of the frame. When it is necessary to adjust the gap between the first sawtooth-shaped friction plate 208 and the second sawtooth-shaped friction plate 212, the workers can move the first sawtooth-shaped friction plate 208 by rotating the bolt 205, so that the gap between the two sawtooth-shaped friction plates can be adjusted. The contact pressure of the friction surface is controlled by the preload of the bolt 205.
