Description

Technical Field

[0001] The present invention relates to the field of building technology, and more particularly to an earthquake-resistant building structure. Background Art

[0002] Earthquake disasters pose a serious threat to the safety of building structures, especially in earthquake-prone areas. Currently, common seismic-resistant building structures primarily include frame structures, shear wall structures, and frame and shear wall structures. Their seismic design is often based on the theory of "ductile seismic resistance," enhancing the structure's seismic resistance through the installation of seismic joints, strengthening components, or employing energy-dissipating devices. However, traditional seismic-resistant structures still exhibit significant drawbacks under strong earthquakes. Firstly, structural components are susceptible to brittle failure due to stress concentration, resulting in a sudden drop in overall stiffness and concentrated deformation, making it difficult to achieve the design goal of "survival in severe earthquakes." Secondly, existing seismic-resistant structural measures often rely on increased material consumption or complex joint designs, which not only increases construction costs but also may restrict building functionality and spatial layout. Furthermore, the contradiction between the seismic performance and economic efficiency of traditional structures is particularly prominent for buildings in high-intensity and active seismic zones.

[0003] Existing earthquake-resistant structures face new challenges in prefabrication applications. The performance of joint connections in prefabricated buildings (such as rebar sleeve grouting and bolted joints) directly impacts the overall seismic performance of the structure. However, existing joint structures are prone to slippage and fracture under the cyclical loads of earthquakes, resulting in insufficient structural energy dissipation and difficulties in post-earthquake repair. Furthermore, traditional earthquake-resistant structures are poorly adaptable to non-seismic forces such as uneven foundation settlement and thermal deformation, and their seismic designs fail to fully account for the coupled effects of multiple adverse factors.

[0004] Therefore, developing a new type of seismic-resistant building structure that combines high ductility, strong energy absorption capacity, convenient construction and environmental adaptability has become a technical problem that needs to be solved urgently in the current construction engineering field.

[0029] Many specific details of the present invention are described in this application, such as the specific structure, size, connection relationship, and technology of the modules, to facilitate a clearer understanding of the present invention. However, as will be appreciated by those skilled in the art, the present invention may be practiced without following these specific details.

[0030] The present invention may be embodied in various forms, some examples of which are described below.

[0031] Figure 1 A schematic diagram of a building seismic structure according to a first embodiment of the present invention is shown; the building seismic structure comprises: a load-bearing box 300 and a building 600 located on the load-bearing box 300, wherein the load-bearing box 300 serves as the base of the building 600 and its size matches that of the building 600, and the building 600 comprises an inner bearing structure 601, an outer bearing structure 602 and an insulation layer 603, wherein the outer bearing structure 602 and the inner bearing structure 601 are respectively connected to the load-bearing box 300, and there is a gap between the outer bearing structure 602 and the inner bearing structure 601, including a vehicle 600. 03 is located between the outer bearing structure 602 and the inner bearing structure 601. This design decouples the outer bearing structure 602 from the inner bearing structure 601 and avoids the problem of the insulation layer 603 being easily damaged and falling off when it is set on the outermost side of the building. The outer bearing structure 602 can be used to support the outer layer 604 such as decorative panels and roof guides used to decorate the building. When strong winds, collisions, earthquakes, etc. occur, the external load and impact are borne by the outer bearing structure 602, reducing the shaking in the bearing structure 603 of the building and ensuring the internal stability and the safety of people and property. Of course, the thickness of the insulation layer 603 between the bottom of the inner bearing structure 601 and the load-bearing box 300 can be slightly thicker than the side. The insulation layer 603 can also play an anti-seismic role. Specifically, the insulation layer 603 is made of, for example, furnace insulation material to achieve a better insulation effect.

[0032] Furthermore, the load-bearing box 300 can also contain liquid. Under normal circumstances, the liquid in the load-bearing box 300 can significantly enhance the stability of the load-bearing box 300. Of course, the liquid in the load-bearing box 300 can also be pumped out for firefighting or watering plants on the building 600 above it. In the event of a disaster such as a flood, the liquid in the load-bearing box 300 can be quickly drained, allowing the load-bearing box 300 and the building above it to float on the water surface, preventing the building from being destroyed by the flood.

[0033] The seismic-resistant structure also includes a limit damper 605, which is located between the inner bearing structure 601 and the outer bearing structure 602. The limit damper 605 is, for example, L-shaped, and its horizontal bottom edge is fixed to the load-bearing box 300 by bolts, and one side of its vertical side is connected to the outer bearing structure 602, and an elastic damping rod is provided on the other side. The elastic damping rod points to the inner bearing structure 601 to limit the inner bearing structure 601, decouple the inner bearing structure 601 from the outer bearing structure 602, and avoid contact or collision between the inner bearing structure 601 and the outer bearing structure 602.

[0034] Figure 2A schematic diagram of a seismic-resistant building structure according to a second embodiment of the present invention is shown; the seismic-resistant building structure includes a foundation pit 100, a liquid 200, a load-bearing box 300, a positioner 400, a support body 500, and a building 600, wherein the building 600 and the load-bearing box 300 are similar to those of the first embodiment and are not described in detail; the size of the foundation pit 100 matches the load-bearing box 300 and the building 600, and the foundation pit 100 has a certain depth to store a sufficient amount of liquid 200, and at least part of the load-bearing box 300 is immersed in the liquid 200 to obtain sufficient buoyancy, and the buoyancy obtained by the load-bearing box 300 is sufficient to support the weight of the load-bearing box 300 and the building 600 on the load-bearing box 300, and the load-bearing box 300 The load-bearing box 300 is connected to the inner wall of the foundation pit 100 via the locator 400. The locator 400 is elastic. By providing the locator 400, the load-bearing box 300 can be fixed, the drift and shaking of the load-bearing box 300 can be reduced, and the load-bearing box 300 can be prevented from contacting or colliding with the side wall of the foundation pit 100. Specifically, the locator 400 includes, for example, a plurality of first locators 401 and a plurality of second locators 402. The first locators 401 are, for example, arranged horizontally and located around the load-bearing box 300 and above the liquid 200. One end of the first locator 401 is connected to the side wall of the foundation pit 100, and the other end is connected to the load-bearing box 300. The second locators 402 are, for example, arranged obliquely and located in the liquid 200. One end of the second locator 402 is connected to the corner of the bottom of the load-bearing box 300, and the other end is connected to the corner of the foundation pit 100.

[0035] Furthermore, a support body 500 is provided under the load-bearing box 300, one end of the support body 500 is connected to the bottom of the foundation pit 100, and the other end of the support body 500 is connected to the lower surface of the load-bearing box. The support body 500 can significantly enhance the stability of the load-bearing box 300 in the liquid 200 and reduce the shaking of the load-bearing box 300; the support body 500 can also provide partial support for the load-bearing box 300, of course, in order to avoid the load-bearing box 300 from shaking too violently after the support body 500 self-destructs, the supporting force of the load-bearing box 300 should be mainly provided by the buoyancy of the liquid 200, and the support body 500 is mainly used for daily fixing of the load-bearing box 300 to reduce the drift of the load-bearing box 300 in the liquid 200.

[0036] The support body 500 also includes a sensor, which is used to sense vibration intensity. When an earthquake occurs, if the vibration intensity sensed by the sensor exceeds a preset value, the support body 500 triggers self-destruction to disconnect the load-bearing box 300 from the bottom of the foundation pit 100, so that the load-bearing box 300 is completely supported by the liquid 200. The positioner 400 is elastic, which allows the load-bearing box to move within a certain range with the liquid level to eliminate the force of the seismic wave.

[0037] Furthermore, the sensor includes, for example, an acceleration sensor and a displacement sensor, so that the self-destruction of the support body 500 has a dual trigger mode of acceleration and displacement. Specifically, the preset vibration intensity corresponding to the self-destruction of the support body 500 is, for example, an acceleration of 0.28g-0.35g or a displacement value of 25mm-35mm. Preferably, when the vibration intensity sensed by the sensor is greater than or equal to 0.3g or 30mm, the support body 500 triggers self-destruction.

[0038] The liquid 200 is, for example, water or liquid flame retardant. Under normal conditions, the weight of the building 600 of the earthquake-resistant structure is shared by the load-bearing box 300 and the support body 500. When an earthquake occurs, the sensor of the support body 500 obtains the vibration intensity of the transmitted seismic wave. If the vibration intensity caused by the earthquake exceeds the preset vibration intensity, the support body 500 self-destructs, and the load-bearing box 300 and the building 600 thereon are completely supported by the liquid 200, and the seismic wave is attenuated by the liquid 200.

[0039] Normally, earthquakes will generate longitudinal waves and transverse waves at the same time. The longitudinal waves will be transmitted to the ground before the transverse waves. If the vibration intensity exceeds the preset vibration intensity, it can trigger the self-destruction of the support body 500, so that the load-bearing box 300 and the building 600 thereon are completely supported by the liquid 200. The liquid 200 attenuates the subsequent transverse waves and seismic waves generated by aftershocks, thereby protecting the safety of the building and the people and objects inside it.

[0040] Furthermore, the foundation pit 100 is provided with an anchor point 101 at a corresponding position of the support body 500. When the support body 500 self-destructs, a new support body 500 can be replaced at the corresponding anchor point 101 for restoration.

[0041] Figure 3A schematic diagram of a seismic-resistant building structure according to a third embodiment of the present invention is shown; the third embodiment is similar to the second embodiment as a whole, and the identical parts are not repeated here. The difference between the third embodiment and the second embodiment is that a sealing bag 201 is further provided in the foundation pit 100, and at least part of the liquid 200 in the foundation pit 100 is sealed in the sealing bag 201, which can effectively reduce the evaporation of the liquid and the growth of algae, sphagnum moss, etc. Although the sealing bags shown in the figure are multiple small sealing bags 201, large sealing bags can also be set up according to needs; further, the support body 500 also includes spikes 501, and the spikes 501 are, for example, arranged on the brittle outer shell of the support body 500. When the support body 500 self-destructs, the spikes 501 will pierce the corresponding sealing bag 201 to allow the liquid 200 inside it to flow out, and the load-bearing box 300 switches to a full buoyancy support state. Specifically, the spikes 501 are, for example, arranged in an array around the support body 500. The support body 500 includes, for example, a brittle composite material, such as carbon fiber reinforced gypsum, and the inclination angle of the spikes 501 is, for example, 20° to 45°. When the support body 500 self-destructs and falls over, the sealing bag 201 is punctured. The sealing bag 201 is, for example, a multi-layer composite structure, which includes an inner layer of flame-retardant film 0.5mm-1mm, a middle layer of tensile fiber mesh (such as Kevlar or basalt fiber) and an outer layer of wear-resistant self-repairing coating; the design of the sealing bag 201 can effectively avoid the reliability of the sealing bag under daily use; of course, all the liquid 200 in the foundation pit 100 can be set in the sealing bag 201, and the ratio of the volume of the sealing bag 201 to the drainage volume of the load-bearing box 300 is, for example, 1.1:1 to 1.3:1.

[0042] Furthermore, the support body 500 may be modularly designed with a quick-release interface, so that after self-destruction, the support body 500 can be quickly and conveniently replaced at the anchor point 101 of the foundation pit 100. The sealing bag 201 may also be pre-packaged and folded, making it easy to replace a punctured sealing bag 201.

[0043] Figure 4 A schematic diagram of a seismic-resistant building structure according to a fourth embodiment of the present invention is shown. This fourth embodiment is generally similar to the second embodiment, and the common features are not further described. This fourth embodiment differs from the second embodiment in that it also includes a drainage pipe 700. The liquid 200 in the foundation pit 100 is, for example, water or a liquid flame retardant (e.g., containing 3% ammonium phosphate flame retardant). One end of the drainage pipe 700 is connected to the liquid 200 in the foundation pit 100, and the other end is connected to the firefighting pipe network of the building 600. This allows the firefighting pipe network of the building 600 to use the liquid in the foundation pit 100 for firefighting. Furthermore, the support body 500 can also be connected to the firefighting system of the building 600 to monitor the operation of the sensors on the support body 500, allowing for timely detection of earthquake conditions and the issuance of earthquake warnings.

[0044] The seismic-resistant structure provided by the embodiment of the present invention adopts an internal-external decoupled load-bearing structure design, effectively avoiding the influence of the structural parts on the exterior of the building on the internal stability of the building. Furthermore, the insulation layer is arranged between the internal and external load-bearing structures. This not only avoids the problem of the insulation layer being easily damaged and detached when arranged on the outermost side of the building, but also acts as an energy-absorbing buffer, thereby enhancing the seismic resistance of the building. Furthermore, the building is placed on a load-bearing box, which is supported by the buoyancy of the liquid and a support body. When the vibration exceeds the preset vibration intensity, the support body self-destructs, causing the load-bearing box and the building to be fully liquid-floating, thereby utilizing the liquid to efficiently attenuate the vibration. The seismic-resistant structure is also provided with a positioning system consisting of multiple positioners, including a first horizontal positioner and a second oblique positioner, to form a three-dimensional constraint network for the load-bearing box, which not only suppresses the sway of the load-bearing box but also prevents the load-bearing box from colliding with the foundation pit. Furthermore, the seismic-resistant structure can be connected to the building's fire protection pipe network, so that the liquid in the foundation pit not only provides earthquake resistance but also serves as an emergency fire water source. The earthquake-resistant structure of the building is simple in structure and easy to construct. It is suitable for a variety of environments and can significantly improve the earthquake resistance of the building.

[0045] While the embodiments of the present invention are described above, these embodiments do not exhaustively describe all details, nor do they limit the present invention to specific embodiments. Obviously, many modifications and variations are possible based on the above description. These embodiments are selected and described in detail in this specification to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to better utilize the present invention and its modifications.
