Description

Technical Field

[0001] This utility model relates to the field of building structure limiting technology, specifically a limiting device for building structures. Background Technology

[0002] With the rapid development of urbanization and the national economy, the application of vibration isolation and seismic resistance technologies and products in building structures is becoming increasingly widespread. Vibration-isolated and seismic-resistant buildings are generally divided into three parts from bottom to top: the building foundation, the isolation layer, and the superstructure. The building foundation supports the superstructure through the isolation layer. The isolation layer is equipped with elastic vibration isolation devices such as rubber bearings and steel spring bearings. These elastic vibration isolation devices can undergo vertical and horizontal deformation, absorbing seismic impacts and energy.

[0003] Currently, to prevent excessive horizontal displacement of the superstructure during earthquakes, building structures for limiting and protecting the structure are usually installed in the seismic isolation layer. However, existing limiting devices for building structures are relatively complex, costly, occupy internal building space, and affect building layout, causing more trouble for actual engineering. Therefore, we propose a limiting device for building structures. Utility Model Content

[0004] The purpose of this utility model is to provide a limiting device for building structures, which has the advantages of simple and beautiful structure, convenient use and low cost. It solves the problems of existing limiting devices for building structures being more complex in structure, more expensive, occupying internal building space, affecting building layout, and causing more trouble for actual engineering.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a limiting device for building structures, comprising a base plate, a limiting seat fixedly connected to the top of the base plate, limiting grooves formed around the perimeter of the limiting seat, a limiting post provided at the middle of the inner cavity of the limiting seat, a top plate fixedly connected to the top of the limiting post, mounting holes formed at the four corners of the top plate and the base plate, and limiting ribs fixedly connected around the perimeter of the outer surface of the limiting post, which are located within the limiting grooves.

[0006] Preferably, there is a gap between the bottom of the limiting post and the top of the base plate to maintain a non-contact state.

[0007] Preferably, there is a gap between the outer surface of the limiting rib and the inner surface of the limiting groove, which is a non-contact state.

[0008] Preferably, a base is provided at each of the four corners of the limiting seat, a buffer seat is provided on the inner side of the base, and a hydraulic damper is fixedly installed on one side of the inner cavity of the buffer seat. There are multiple hydraulic dampers, and the distance between two adjacent hydraulic dampers is equal.

[0009] Preferably, a movable block that slides within a buffer seat is fixedly installed at one end of the hydraulic damper, and a buffer spring sleeved on the outside of the hydraulic damper is fixedly connected between the movable block and one side of the inner cavity of the buffer seat.

[0010] Preferably, an arc-shaped push plate that fits against the outer surface of the limiting post is fixedly connected to the side of the movable block away from the base. A base plate is provided at both ends of the base, and an air spring is fixedly installed between the base plate and the arc-shaped push plate.

[0011] Preferably, there are multiple air springs, and the distance between any two adjacent air springs is equal.

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

[0013] 1. This utility model, through the setting of bolts and mounting holes, allows the bottom plate and top plate to be installed on the building foundation and the superstructure respectively. When an earthquake or other special circumstances occur, the superstructure will undergo lateral displacement, which will drive the limiting column and limiting rib plate to move through the top plate until the limiting rib plate contacts the corresponding limiting groove, so that the limiting device generates lateral resistance, thereby limiting the superstructure from excessive displacement and protecting the superstructure. Its structure is simple and beautiful, easy to use, and low in cost.

[0014] 2. This utility model, through the setting of the arc-shaped push plate, enables the upper building to move via the top plate when lateral displacement occurs due to earthquakes or other special circumstances. The movement of the upper building is driven by the limit column and the limit rib plate. When the limit column moves, it can drive the movable block to slide on the inner side of the buffer seat via the contacting arc-shaped push plate, thereby compressing the hydraulic damper and the buffer spring. At the same time, with the assistance of the base and the base plate, the air spring at the corresponding position will also be subjected to compressive force as the arc-shaped push plate moves. This can buffer and isolate the upper building when lateral displacement occurs, and avoid the noise caused by rigid contact between the limit rib plate and the corresponding limit groove.

In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0023] The components of this application, including the base plate 1, top plate 2, limiting seat 3, limiting groove 4, limiting rib plate 5, limiting post 6, buffer seat 7, hydraulic damper 8, buffer spring 9, movable block 10, arc-shaped push plate 11, base 12, base plate 13, and air spring 14, are all general standard parts or parts known to those skilled in the art.

[0024] Example 1

[0025] Please see Figures 1-4As shown, this utility model provides a technical solution: a limiting device for building structures, including a base plate 1, a limiting seat 3 fixedly connected to the top of the base plate 1, limiting grooves 4 opened around the perimeter of the limiting seat 3, a limiting post 6 provided at the middle of the inner cavity of the limiting seat 3, a gap between the bottom of the limiting post 6 and the top of the base plate 1 for non-contact, a top plate 2 fixedly connected to the top of the limiting post 6, mounting holes opened at the four corners of the top plate 2 and the base plate 1, and limiting ribs 5 located in the limiting grooves 4 fixedly connected around the perimeter of the outer surface of the limiting post 6, a gap between the outer surface of the limiting ribs 5 and the inner surface of the limiting grooves 4 for non-contact.

[0026] This technical solution allows the base plate 1 and top plate 2 to be installed on the building foundation and superstructure respectively via bolts and mounting holes. A gap exists between the bottom of the limiting column 6 and the top of the base plate 1, ensuring non-contact. Similarly, a gap exists between the outer surface of the limiting rib 5 and the inner surface of the limiting groove 4, also ensuring non-contact. The gaps between these gaps do not exceed the maximum allowable displacement of the superstructure, and the lateral limiting gap between the limiting rib 5 and the limiting groove 4 is maintained at the design value. In the event of an earthquake or other special circumstances, lateral displacement of the superstructure will be caused by the top plate 2, moving the limiting column 6 and the limiting rib 5 until they contact the corresponding limiting groove 4. This generates lateral resistance, limiting excessive displacement of the superstructure and providing protection. The solution is simple, aesthetically pleasing, easy to use, and low in cost.

[0027] Example 2

[0028] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, a base 12 is provided at each of the four corners of the limiting seat 3. A buffer seat 7 is provided on the inner side of the base 12. A hydraulic damper 8 is fixedly installed on one side of the inner cavity of the buffer seat 7. There are multiple hydraulic dampers 8, and the distance between two adjacent hydraulic dampers 8 is equal. A movable block 10 that slides in the buffer seat 7 is fixedly installed at one end of the hydraulic damper 8. A buffer spring 9 sleeved on the outside of the hydraulic damper 8 is fixedly connected between the movable block 10 and one side of the inner cavity of the buffer seat 7. An arc-shaped push plate 11 that fits against the outer surface of the limiting post 6 is fixedly connected to the side of the movable block 10 away from the base 12. A base plate 13 is provided at both ends of the base 12. An air spring 14 is fixedly installed between the base plate 13 and the arc-shaped push plate 11. There are multiple air springs 14, and the distance between two adjacent air springs 14 is equal.

[0029] This technical solution: By setting the arc-shaped push plate 11, when the upper building undergoes lateral displacement due to an earthquake or other special circumstances, the upper building can move the limiting column 6 and the limiting rib plate 5 via the top plate 2. When the limiting column 6 moves, it can drive the movable block 10 to slide on the inner side of the buffer seat 7 via the contacting arc-shaped push plate 11, thereby squeezing the hydraulic damper 8 and the buffer spring 9. At the same time, with the assistance of the base 12 and the base plate 13, as the arc-shaped push plate 11 moves, the air spring 14 at the corresponding position will also be subjected to the squeezing force, thereby providing the ability to buffer and isolate the upper building when it undergoes lateral displacement, and avoiding the noise impact caused by the rigid contact between the limiting rib plate 5 and the corresponding limiting groove 4.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
