Abstract

This application discloses a seismic-resistant building structure, comprising: a load-bearing box serving as the foundation of the building; a building situated on the load-bearing box, the building having an inner load-bearing structure, an outer load-bearing structure, and an insulation layer; wherein the outer load-bearing structure and the inner load-bearing structure are respectively connected to the load-bearing box, with a gap between the outer load-bearing structure and the inner load-bearing structure, and the insulation layer located between the outer load-bearing structure and the inner load-bearing structure.

Description

Technical Field

[0001] This utility model relates to the field of building technology, and more specifically, to a seismic-resistant building structure. Background Technology

[0002] Earthquakes pose a serious threat to the safety of building structures, especially in earthquake-prone areas, where the seismic performance of buildings directly affects the safety of people's lives and property and social stability. Currently, common seismic-resistant building structures mainly include frame structures, shear wall structures, and frame-shear wall structures. Their seismic design is mostly based on the "ductile seismic resistance" theory, improving the structure's seismic capacity through methods such as setting seismic joints, strengthening component strength, or using energy dissipation devices. However, traditional seismic-resistant structures still have significant shortcomings under strong earthquakes: on the one hand, structural components are prone to brittle failure due to stress concentration, leading to a sharp drop in overall stiffness and concentrated deformation, making it difficult to achieve the design goal of "not collapsing under major earthquakes"; on the other hand, existing seismic-resistant structural measures often rely on increasing material usage or complex node designs, which not only increases construction costs but may also restrict the building's functionality and spatial layout. Furthermore, for buildings in high-intensity earthquake zones and active seismic belts, the contradiction between the seismic performance and economy of traditional structures is particularly prominent.

[0003] Existing seismic-resistant structures face new challenges in prefabricated assembly applications. The performance of joint connections in prefabricated buildings (such as grouted steel sleeve connections and bolted joints) directly affects the overall seismic performance of the structure. However, existing connection structures are prone to slippage and breakage under cyclic seismic loads, resulting in insufficient energy dissipation capacity and difficulties in post-earthquake repair. Furthermore, traditional seismic-resistant structures are poorly adapted to non-seismic forces such as uneven foundation settlement and temperature deformation, and their seismic design fails to fully consider the coupling effects of various adverse factors.

[0004] Therefore, developing a new type of earthquake-resistant building structure that combines high ductility, strong energy dissipation capacity, convenient construction, and environmental adaptability has become an urgent technical challenge to be solved in the field of building engineering.

[0005] The purpose of this invention is to provide a seismic-resistant building structure to improve the seismic performance of existing buildings.

[0006] According to one aspect of this utility model, a seismic-resistant building structure is provided, comprising: a load-bearing box as the base of a building; a building located on the load-bearing box, the building having an inner load-bearing structure, an outer load-bearing structure, and an insulation layer; wherein the outer load-bearing structure and the inner load-bearing structure are respectively connected to the load-bearing box, a gap exists between the outer load-bearing structure and the inner load-bearing structure, and the insulation layer is located between the outer load-bearing structure and the inner load-bearing structure.

[0007] Optionally, it also includes a limiting damper, which is located between the inner bearing structure and the outer bearing structure. The limiting damper is L-shaped, and its bottom is fixed to the load-bearing box by bolts. The limiting damper is used to limit the inner bearing structure, thereby decoupling the inner bearing structure from the outer bearing structure.

[0008] Optionally, the load-bearing box may also contain liquid that can be used for fire protection of the building.

[0009] Optionally, it further includes: a foundation pit located below the building for storing liquid, the load-bearing box located in the foundation pit and floating on the liquid; a locator located around the load-bearing box to prevent the load-bearing box from contacting the side wall of the foundation pit; a support body located in the foundation pit, one end of the support body connected to the bottom of the foundation pit and the other end of the support body connected to the load-bearing box; wherein, when the vibration exceeds a preset vibration intensity, the support body self-destructs, so that the load-bearing box is supported by the liquid.

[0010] Optionally, the locator includes a first locator and a second locator. The first locator is arranged horizontally, and the second locator is arranged obliquely. The first locator is located around the load-bearing box, one end of the second locator is connected to the bottom corner of the load-bearing box, and the other end of the second locator is connected to the inner wall of the pit.

[0011] Optionally, it also includes a sealing bag located in the pit, wherein at least a portion of the liquid is sealed by the sealing bag.

[0012] Optionally, the sealing bags include a plurality of bags, each sealing the liquid in the pit to form a plurality of independent sealing bags containing the liquid.

[0013] Optionally, the sealed bag comprises a multi-layer composite structure.

[0014] Optionally, the support further includes spikes that puncture the sealed bag when the support self-destructs.

[0015] Optionally, the liquid includes at least one of water and liquid flame retardant.

[0016] Optionally, it also includes a diversion pipe, one end of which is connected to the liquid and the other end of which is connected to the building's fire protection network.

[0018] Optionally, the sensor includes an acceleration sensor and a displacement sensor, and the self-destruct trigger parameter of the support includes at least one of acceleration and displacement.

[0019] The seismic-resistant building structure provided in this embodiment of the invention adopts an internal and external decoupled load-bearing structure design, effectively avoiding the impact of the external structural parts of the building on the internal stability of the building. Furthermore, an insulation layer is placed between the internal and external load-bearing structures, not only avoiding the problem of easy damage and detachment of the insulation layer placed on the outermost part of the building, but also acting as an energy-absorbing buffer, enhancing the building's seismic resistance. Further, the building is placed on a load-bearing box, which is supported by the buoyancy of the liquid and the supporting structure. When the vibration exceeds the preset vibration intensity, the supporting structure self-destructs, causing the load-bearing box and the building to enter a fully liquid-floating state, utilizing the liquid to efficiently attenuate the vibration. This seismic-resistant building structure also features a positioning system composed of multiple locators, including a first lateral locator and a second oblique locator, forming a three-dimensional constraint network for the load-bearing box, suppressing its swaying and preventing collisions between the load-bearing box and the foundation pit. Furthermore, this seismic-resistant building structure can be connected to the building's fire protection network, allowing the liquid in the foundation pit to function as an emergency fire-fighting water source in addition to its seismic resistance function. The seismic-resistant structure of this building is simple in structure and easy to construct. It is suitable for various environments and can significantly improve the seismic performance of the building. Attached Figure Description

[0030] This utility model can be presented in various forms, some of which will be described below.

[0031] Figure 1 This diagram illustrates a seismic-resistant building structure according to a first embodiment of the present invention. The seismic-resistant building structure includes a load-bearing box 300 and a building 600 located on the load-bearing box 300. The load-bearing box 300 serves as the base of the building 600, and its dimensions match those of the building 600. The building 600 includes an inner load-bearing structure 601, an outer load-bearing structure 602, and an insulation layer 603. The outer load-bearing structure 602 and the inner load-bearing structure 601 are respectively connected to the load-bearing box 300, and a gap exists between the outer load-bearing structure 602 and the inner load-bearing structure 601. Located between the outer load-bearing structure 602 and the inner load-bearing structure 601, the insulation layer 603 decouples from the outer load-bearing structure 602 and the inner load-bearing structure 601. This design also avoids the problem of the insulation layer 603 being easily damaged and detached when located on the outermost side of the building. The outer load-bearing structure 602 can support the decorative panels, roof guides, and other outer layers 604 used for building decoration. When external winds, impacts, earthquakes, etc., occur, the external load and impact are borne by the outer load-bearing structure 602, reducing the swaying in the inner load-bearing structure 603 and ensuring internal stability and the safety of personnel and property. Of course, the thickness of the insulation layer 603 between the bottom of the inner load-bearing structure 601 and the load-bearing box 300 can be slightly thicker than the sides. This insulation layer 603 also provides seismic resistance. Specifically, the insulation layer 603 can, for example, use furnace-enclosed thermal insulation materials to achieve better insulation performance.

[0032] Furthermore, the load-bearing tank 300 can also hold liquid. Under normal circumstances, the liquid inside the load-bearing tank 300 can significantly enhance its stability. Of course, the liquid inside the load-bearing tank 300 can also be extracted for fire fighting or watering of the building 600 above it. In the event of a disaster such as a flood, the liquid inside the load-bearing tank 300 can be quickly drained, allowing the load-bearing tank 300 and the building above it to float on the water's surface, preventing the building from being destroyed by the flood.

[0033] The seismic-resistant structure also includes a limiting damper 605, which is located between the inner bearing structure 601 and the outer bearing structure 602. The limiting damper 605 is, for example, L-shaped, with its horizontal bottom edge fixed to the load-bearing box 300 by bolts. One of its vertical sides is connected to the outer bearing structure 602, and the other side is provided with an elastic damping rod. The elastic damping rod points towards the inner bearing structure 601 to limit the inner bearing structure 601, thereby decoupling the inner bearing structure 601 from the outer bearing structure 602 and preventing the inner bearing structure 601 from contacting or colliding with the outer bearing structure 602.

[0034] Figure 2 This diagram illustrates a seismic-resistant building structure according to a second embodiment of the present invention. The seismic-resistant building structure includes a foundation pit 100, a liquid 200, a load-bearing box 300, a locator 400, a support 500, and a building 600. The building 600 and the load-bearing box 300 are similar to those in the first embodiment, and will not be described again. The dimensions of the foundation pit 100 are matched to the load-bearing box 300 and the building 600. The foundation pit 100 has a certain depth to store sufficient liquid 200. At least a portion of the load-bearing box 300 is immersed in the liquid 200 to obtain sufficient buoyancy. 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. A locator 400 is also provided around the 0. The load-bearing box 300 is connected to the inner wall of the pit 100 through the locator 400. The locator 400 is elastic. By setting the locator 400, the load-bearing box 300 can be fixed, reducing the drift and shaking of the load-bearing box 300 and preventing the load-bearing box 300 from contacting or colliding with the side wall of the pit 100. Specifically, the locator 400 includes, for example, multiple first locators 401 and multiple second locators 402. The first locators 401 are arranged horizontally, 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 pit 100, and the other end is connected to the load-bearing box 300. The second locators 402 are arranged obliquely and located in the liquid 200. One end of the second locator 402 is connected to the bottom corner of the load-bearing box 300, and the other end is connected to the corner of the pit 100.

[0035] Furthermore, a support body 500 is also provided below 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 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. The support body 500 is mainly used for daily fixing of the load-bearing box 300 and reducing the drift of the load-bearing box 300 in the liquid 200.

[0036] The support 500 also includes a sensor for sensing vibration intensity. When an earthquake occurs, if the vibration intensity sensed by the sensor exceeds a preset value, the support 500 triggers self-destruction to disconnect the load-bearing box 300 from the bottom of the 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 surface to eliminate the force of the seismic wave.

[0037] Furthermore, the sensors include, for example, an acceleration sensor and a displacement sensor, so that the self-destruction of the support 500 has a dual triggering mode of acceleration and displacement. Specifically, the preset vibration intensity corresponding to the self-destruction of the support 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 500 triggers self-destruction.

[0038] Liquid 200 is, for example, water or liquid flame retardant. Under normal conditions, the weight of the building 600 is borne by the load-bearing box 300 and the support body 500. When an earthquake occurs, the sensors of the support body 500 acquire the vibration intensity of the transmitted seismic waves. 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 on it are completely supported by the liquid 200, which attenuates the seismic waves.

[0039] Normally, an earthquake generates both longitudinal and transverse waves. The longitudinal waves are transmitted to the ground first, relative to the transverse waves. If the vibration intensity exceeds the preset vibration intensity, it can trigger the self-destruction of the support structure 500, so that the load-bearing box 300 and the building 600 on it 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.

[0040] Furthermore, the foundation pit 100 is also provided with anchor points 101 at the corresponding positions 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 3 This diagram shows a third embodiment of the earthquake-resistant building structure of the present invention. The third embodiment is similar to the second embodiment in general, and the same parts will not be described again. The difference between the third embodiment and the second embodiment is that a sealing bag 201 is also provided in the foundation pit 100. 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 liquid and the growth of algae, moss and the like. Although the sealing bags shown in the figure are multiple small sealing bags 201, large sealing bags can also be provided as needed; furthermore, the support body 500 also includes spikes 501, which are provided, for example, on the brittle outer shell of the support body 500. When the support body 500 self-destructs, the spikes 501 will puncture the corresponding sealing bag 201, causing the liquid 200 inside to flow out, and the load-bearing box 300 will switch to a full buoyancy support state. Specifically, the spikes 501 are arranged in an array around the support body 500, for example, the support body 500 is made of a brittle composite material, such as carbon fiber reinforced gypsum, etc. The tilt angle of the spikes 501 is, for example, 20° to 45°, so that the sealing bag 201 will be punctured when the support body 500 self-destructs and tilts. The sealing bag 201 is, for example, a multi-layer composite structure, including an inner flame-retardant membrane of 0.5mm-1mm, a middle tensile fiber mesh (e.g., Kevlar or basalt fiber), and an outer wear-resistant self-healing coating. This sealing bag 201 design can effectively avoid reliability issues in daily use. Of course, all the liquid 200 in the pit 100 can be placed in the sealing bag 201, and the ratio of the volume of the sealing bag 201 to the drainage capacity of the load-bearing box 300 is, for example, 1.1:1 to 1.3:1.

[0042] Furthermore, the support body 500 may employ a modular design with quick-release interfaces, allowing for quick and convenient replacement at the anchor point 101 in the pit 100 after the support body 500 self-destructs. The sealing bag 201 may also employ a pre-sealed folding design for easy replacement of any punctured sealing bags.

[0043] Figure 4This diagram illustrates a fourth embodiment of the earthquake-resistant building structure of the present invention. The fourth embodiment is generally similar to the second embodiment, and the identical parts will not be repeated. The difference between the fourth and second embodiments lies in the inclusion of a diversion pipe 700. The liquid 200 in the pit 100 is, for example, water or a liquid flame retardant (such as one containing 3% ammonium phosphate flame retardant). One end of the diversion pipe 700 is connected to the liquid 200 in the pit 100, and the other end is connected to the fire protection network of the building 600, allowing the fire protection network of the building 600 to use the liquid in the pit 100 for fire extinguishing and fire prevention. Furthermore, the support 500 can also be connected to the fire protection system of the building 600 to monitor the operation of the sensors on the support 500, promptly detect earthquakes, and issue earthquake warnings.

[0044] The seismic-resistant building structure provided in this embodiment of the invention adopts an internal and external decoupled load-bearing structure design, effectively avoiding the impact of the external structural parts of the building on the internal stability of the building. Furthermore, an insulation layer is placed between the internal and external load-bearing structures, not only avoiding the problem of easy damage and detachment of the insulation layer placed on the outermost part of the building, but also acting as an energy-absorbing buffer, enhancing the building's seismic resistance. Further, the building is placed on a load-bearing box, which is supported by the buoyancy of the liquid and the supporting structure. When the vibration exceeds the preset vibration intensity, the supporting structure self-destructs, causing the load-bearing box and the building to enter a fully liquid-floating state, utilizing the liquid to efficiently attenuate the vibration. This seismic-resistant building structure also features a positioning system composed of multiple locators, including a first lateral locator and a second oblique locator, forming a three-dimensional constraint network for the load-bearing box, suppressing its swaying and preventing collisions between the load-bearing box and the foundation pit. Furthermore, this seismic-resistant building structure can be connected to the building's fire protection network, allowing the liquid in the foundation pit to function as an emergency fire-fighting water source in addition to its seismic resistance function. The seismic-resistant structure of this building is simple in structure and easy to construct. It is suitable for various environments and can significantly improve the seismic performance of the building.

[0045] The embodiments of this utility model described above are examples of specific examples. These embodiments do not exhaustively describe all details, nor do they limit the utility model to only specific embodiments. Obviously, many modifications and variations can be made based on the above description. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to make good use of this utility model and its modifications.
