Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building technology, specifically relating to an adaptive building seismic isolation trench cover structure. Background Technology
[0002] Vibration isolation trenches are a type of vibration isolation building structure applied to buildings. Their vibration isolation principle is to separate the building foundation from the surrounding foundation by establishing trenches of a certain width and depth, thereby reducing the impact of external forces such as earthquakes and wind vibrations on the building. The vibration isolation trench cover plate is a cover plate that covers the surface of the vibration isolation trench, serving to protect the vibration isolation trench. Traditional vibration isolation trench cover plate devices cannot effectively adapt to the deformation and displacement of the building during long-term use when earthquakes or slow ground deformation occur, resulting in a loss of protective effect and potentially causing damage to the vibration isolation trench structure.

[0015] To more intuitively and clearly describe the specific details of the technical solution of this utility model, a detailed description will be provided below in conjunction with specific embodiments and example drawings.
[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0017] like Figure 1 As shown, the adaptive building seismic isolation trench cover structure of this utility model includes a cover body 1. The first end of the cover body 1 is rotatably connected to a support bearing 2 installed at one end of the seismic isolation trench 5. The second end of the cover body 1 is located at the other end of the seismic isolation trench 5. The seismic isolation trench cover structure also includes a sliding support 3 fixed to the outside of the seismic isolation trench and located below the cover body to support the cover body.
[0018] The sliding bearing and the cover plate body are usually made of smooth metal surface. The cover plate body is normally supported by the sliding bearing, which is fixed to the ground on both sides of the seismic isolation trench. When the ground surface deforms due to earthquake or other reasons, the cover plate body can move horizontally along the sliding bearing. At the same time, the support bearing allows the cover plate body to tilt vertically, so that the cover plate body can move in both horizontal and vertical directions. However, while displacing, it is fixed to one end of the seismic isolation trench by the support bearing. This allows the cover plate body to deform with the seismic isolation trench and continue to maintain the state of covering and protecting the seismic isolation trench.
[0019] The cover plate body is the main load-bearing component, and its service life needs to be the same as the building's lifespan. It is typically made of corrosion-resistant alloy materials. The contact surfaces between the cover plate body and the sliding bearing can be metal-surface treated to reduce the coefficient of sliding friction between them, thereby ensuring that the structures above the cover plate body can slide with the displacement of the seismic isolation trench. The sliding bearing can be installed on one side of the seismic isolation trench or on the ground on both sides of the trench. Support bearing.
[0020] Figure 1 In the specific embodiment shown, the seismic isolation trench cover plate structure also includes an inclined support device 4 fixed on the outside of the seismic isolation trench and located on one side of the second end of the cover plate body. The inclined support device 4 can be a reinforced concrete structure formed by earthwork operations, used to ensure that the displacement of the cover plate body is within a controllable range, and to reduce the damage to the building caused by excessive displacement of the cover plate body. The bearing seat of the support bearing can be pre-embedded on the outside of the seismic isolation trench to achieve firm fixation.
[0021] like Figure 2 The diagram shows another specific embodiment of the adaptive building seismic isolation trench cover structure of this utility model. A bearing bracket 7 is provided below the supporting bearing, and a seismic isolation trench sidewall fixing device is provided on the side of the bearing bracket. Figure 2 The specific implementation shown allows the bearing bracket 7 to be fixed on the inner side wall of the vibration isolation trench and positioned opposite to the outer side of the vibration isolation trench 5. This reduces the floor space occupied by the cover plate structure and prevents the bearing support installed on the outer side of the vibration isolation trench from being damaged by external forces such as vehicle impacts. Figure 2 In the specific embodiment shown, a dust cover 6 is provided above the support bearing to extend the service life of the support bearing.
[0022] like Figure 3 The diagram shows another specific embodiment of the adaptive building seismic isolation trench cover structure of this utility model, wherein the bearing seat of the supporting bearing 2 is connected to the cover body 1 through an elastic device 8. Figure 3 In the specific embodiment shown, the elastic device mainly provides restoring force for instantaneous impacts such as earthquakes and explosions, so that the cover plate body can return to its original position after being displaced by a brief impact. The elastic device enables an elastic connection between the cover plate body and the support bearing. Since the support bearing is the lever fulcrum of the cover plate body, it is subjected to greater force, which can also reduce the damage to the bearing when an impact occurs.
[0023] The adaptive building seismic isolation trench cover structure of this utility model can automatically adjust the position and angle of the cover to adapt to the deformation and displacement of the building, thereby improving the seismic isolation effect. By setting spring components and sliding components, elastic support and sliding adjustment of the seismic isolation trench cover are realized, improving the adaptability and stability of the device. The installation method of the adaptive building seismic isolation trench cover structure of this utility model is simple and convenient, easy to implement, and suitable for the seismic isolation needs of various building structures.
[0024] The foregoing descriptions are preferred embodiments of this utility model.
