Description

Technical Field

[0001] The utility model belongs to the technical field of shock absorption, and particularly relates to a friction shock absorption bearing for buildings. Background Art

[0002] As a serious natural disaster, an earthquake often causes the destruction or even collapse of engineering structures in the earthquake area due to its huge effect. A shock absorption bearing is to set an isolation device at the base or a certain position of a building or structure to isolate or dissipate seismic energy, so as to avoid or reduce the transmission of seismic energy to the upper structure, reduce the vibration response of the structure, and make the building only have slight movement and deformation during an earthquake, thus avoiding the destruction or collapse of the structure and ensuring the safety of the building during an earthquake.

[0003] With the rapid development of society and the improvement of people's living quality, various buildings have sprung up. However, in the existing building structure shock absorption devices, almost no device is set to eliminate the lateral shear force of the building structure or simply rely on a soft cushion layer to offset it, resulting in less resistance of the building structure to the lateral shear force and bringing great potential safety hazards to people's living or working. Content of the Utility Model

[0004] In view of this, the purpose of the utility model is to provide a friction shock absorption bearing for buildings to solve the technical problem that the existing shock absorption device has poor effect in eliminating the lateral shear force of the building structure, resulting in less resistance of the building structure to the lateral shear force.

[0005] To achieve the above purpose, the technical solution adopted by a friction shock absorption bearing for buildings of the utility model is as follows:

[0006] A friction shock absorption bearing for buildings, comprising:

[0007] A base: including a base plate and left and right vertical plates fixed on the left and right sides of the base plate;

[0008] A support frame: arranged at intervals above the base plate, and the support frame is arranged between the left and right vertical plates;

[0009] The support frame is U-shaped, including a horizontally arranged support plate and left and right limit plates fixed on the left and right sides of the support plate;

[0010] A plurality of rubber cylinders are fixedly arranged between the base plate and the support plate;

[0011] A top plate: arranged at intervals above the support plate, and the left and right sides of the top plate are respectively in guiding fit with the left and right limit plates;

[0012] A vertical elastic telescopic structure: arranged between the top plate and the support plate in the up and down direction;

[0013] Transverse elastic telescopic structure: arranged between the left vertical plate and the left limit plate, and between the right vertical plate and the right limit plate in the left and right directions respectively;

[0014] The transverse elastic telescopic structure comprises a left transverse elastic telescopic structure and a right transverse elastic telescopic structure which are symmetrically arranged on the left and right sides;

[0015] The left end of the left transverse elastic telescopic structure is fixed on the left vertical plate, and the right end is slidably matched with the left limit plate; the right end of the right transverse elastic telescopic structure is fixed on the right vertical plate, and the left end is slidably matched with the right limit plate.

[0016] Beneficial effect: A friction shock-absorbing bearing for construction in the utility model includes a vertical elastic telescopic structure arranged between a top plate and a support plate in the up and down directions. The arrangement of the vertical elastic telescopic structure can enable the building structure to have a stronger effect of resisting vertical loads. Moreover, in the left and right directions, the left lateral elastic telescopic structure arranged between the left vertical plate and the left limiting plate, and the right lateral elastic telescopic structure arranged between the right vertical plate and the right limiting plate make the building structure more resistant to lateral shear forces. That is, the building structure can not only have a greater resistance to vertical loads but also have a greater resistance to lateral shear forces, thereby enabling the building structure to withstand damage caused by natural disasters such as earthquakes.

[0017] Furthermore, the left side transverse elastic telescopic structure includes a rectangular guide seat and a guide plug adapted to guide the rectangular guide seat;

[0018] The rectangular guide seat comprises a receiving cavity, and a left opening communicating with the inside and outside of the receiving cavity is provided on the rectangular guide seat;

[0019] The guide plug includes a left fixed plate fixedly connected to the left vertical plate, a left connecting plate vertically fixedly connected to the left fixed plate, and a left guide plate vertically fixedly connected to the left connecting plate;

[0020] The left connecting plate extends from the left opening into the accommodating cavity, and the left guide plate is located in the accommodating cavity and is adapted to guide the accommodating cavity;

[0021] A compression spring is fixed between the left fixed plate and the rectangular guide seat.

[0022] Beneficial effect: When the building structure is subjected to lateral shear force, the lateral elastic telescopic structure on one side of the building structure can be compressed under the action of the compression spring, and the lateral elastic telescopic structure on the other side can be extended, thereby absorbing the lateral load and avoiding damage to the building structure caused by the lateral shear force.

[0023] Furthermore, an elastic buffer layer is fixed to the side of the left guide plate facing away from the left connecting plate, and the elastic buffer layer includes a raised elastic column; and an elastic cushion layer is fixed to the side of the accommodating cavity corresponding to the left opening.

[0024] Beneficial effects: The elastic buffer layer and the elastic cushion layer are structured in such a way that when the building structure is subjected to lateral loads, the rectangular guide seat and the guide plug can buffer when they come into lateral top pressure contact, minimizing the damage caused by lateral loads to the building structure.

[0025] The vertical elastic telescopic structure includes a guide cylinder fixed on the support plate. An avoidance hole is provided at the upper end of the guide cylinder. A guide post is slidably and adaptively arranged in the guide cylinder. The guide post includes a column body extending in the up and down directions and a baffle fixed at the lower end of the column body. The column body passes through the avoidance hole, and the upper end of the guide post is fixedly connected to the top plate. The baffle is slidably and adaptively arranged with the inner wall surface of the guide cylinder, and the baffle and the avoidance hole are in a blocking fit in the up and down directions. A first elastic structure is arranged on the guide post, and a second elastic structure is arranged between the baffle and the bottom of the guide cylinder.

[0026] Beneficial effects: The vertical elastic telescopic structure can absorb the loads generated in the up and down directions and has a simple structure.

[0027] Further, the first elastic structure is a first spring, and the second elastic structure is a second spring.

[0028] Beneficial effects: The first elastic structure and the second elastic structure have a simple structure.

[0029] A guide sliding structure is arranged between the left and right sides of the top plate and the left and right limit plates respectively.

[0030] Beneficial effects: The arrangement of the guide sliding structure can make the top plate more stable during the up and down movement.

[0031] Further, the guide sliding structure includes a limiting groove extending in the up and down directions formed on the limit plate and a limiting block fixed on the top plate and slidably and adaptively arranged with the limiting groove.

[0032] Beneficial effects: The arrangement of the limiting groove and the limiting block makes the arrangement of the guide sliding structure simpler.

[0033] Four rubber cylinders are arranged between the base and the support plate and are arranged in a rectangular array at the four corners of the support plate.

[0034] Beneficial effects: The rubber cylinders can stably support the support plate. Description of the drawings

In this embodiment, four rubber cylinders 4 are arranged between the base 1 and the support plate 5, and are arranged in a rectangular array at the four corners of the support plate 5

[0040] A top plate 8 is arranged at intervals above the support plate 5. The left and right sides of the top plate 8 are respectively in guiding fit with the left and right limit plates 6 and 7. In this embodiment, a guiding sliding structure is arranged between the left and right sides of the top plate 8 and the left and right limit plates 6 and 7 respectively. The guiding sliding structure includes a limit groove 9 extending in the up and down direction opened on the limit plate and a limit block 10 fixed on the top plate 8 and in guiding sliding fit with the limit groove 9

[0041] In the up - down direction, a vertical elastic telescopic structure is provided between the top plate 8 and the support plate 5. In this embodiment, the vertical elastic telescopic structure includes a guide cylinder 14 fixed on the support plate 5. An avoidance hole is provided at the upper end of the guide cylinder 14.

The column body 11 passes through the avoidance hole, and the upper end of the guide post is fixedly connected to the top plate 8. The baffle 12 is slidably fitted with the inner wall surface of the guide cylinder 14, and in the up - down direction, the baffle 12 is in a blocking fit with the avoidance hole. A first elastic structure is provided on the guide post. In this embodiment, the first elastic structure is a first spring 13. A second elastic structure is provided between the baffle 12 and the bottom of the guide cylinder 14. In this embodiment, the second elastic structure is a second spring 17.

[0042] In the left - right direction, a transverse elastic telescopic structure is provided between the left vertical plate 2 and the left limiting plate 6, and between the right vertical plate 3 and the right limiting plate 7. The transverse elastic telescopic structure includes a left - hand transverse elastic telescopic structure 15 and a right - hand transverse elastic telescopic structure 16 which are symmetrically arranged left and right. The left end of the left - hand transverse elastic telescopic structure 15 is fixed on the left vertical plate 2, and the right end is slidably mated with the left limiting plate 6. The right end of the right - hand transverse elastic telescopic structure 16 is fixed on the right vertical plate 3, and the left end is slidably mated with the right limiting plate 7.

[0043] Taking the left - hand transverse elastic telescopic structure 15 as an example, the specific structure of the transverse elastic telescopic structure is introduced. Specifically, the left - hand transverse elastic telescopic structure 15 includes a rectangular guide seat 22 and a guide plug that is slidably fitted with the rectangular guide seat 22. In this embodiment, the right side of the rectangular guide seat 22 is in a pressing and sliding fit with the left limiting plate 6, and the contact surface between the rectangular guide seat 22 and the left limiting plate 6 is polished to reduce friction.

[0044] The rectangular guide seat 22 includes a receiving cavity, and a left opening communicating the inside and outside of the receiving cavity is provided on the rectangular guide seat 22.

[0047] When the friction shock-absorbing bearing for buildings of the present utility model is in use, the building structure is fixed to the top plate 8. Under the action of its own weight, the building structure can squeeze the vertical elastic telescopic structure. At this time, both the first spring 13 and the second spring 17 are compressed, and the guide post moves downward relative to the guide cylinder 14; if a large vertical load is encountered during an earthquake, the first spring 13 and the second spring 17 will be further compressed.
