Description

Technical Field

[0001] This invention relates to the field of construction, specifically to a structural support device based on a building disaster prevention and early warning system. Background Technology

[0002] As my country's urbanization continues to advance, rural populations are increasingly concentrating in cities, leading to a growing shortage of urban construction land. To achieve intensive development and utilization of urban land resources and alleviate the imbalance between housing supply and demand, high-rise buildings have become a crucial development direction in urban planning and construction. However, with the continuous increase in building height, the requirements for structural load-bearing capacity and stiffness become increasingly stringent. Especially for super high-rise buildings with weak structural layers, numerous shear wall openings, and uneven structural layout, they are highly susceptible to excessive structural deformation, cracking, or component failure due to insufficient load-bearing capacity and stiffness when encountering external disasters such as earthquakes, typhoons, and explosions. Simply increasing reinforcement and component dimensions for low-probability events like earthquakes, typhoons, and explosions would lead to increased construction costs and wasted building space. Summary of the Invention

[0003] In view of this, the present invention provides a structural support device based on a building disaster prevention and early warning system. This structural support device, controlled by the building disaster prevention and early warning system, can specifically enhance the load-bearing capacity and stiffness of a high-rise building structure during disasters, solving or mitigating the problems of excessive structural deformation, cracking, and component failure in traditional high-rise buildings caused by external disasters such as earthquakes, typhoons, and explosions.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a structural support device based on a building disaster prevention and early warning system, comprising diagonal braces, a protective cover, a booster, and a signal receiver. The diagonal brace consists of a strut, a hinge joint, and a fastening joint. One end of the strut is connected to the fastening joint, and the other end is connected to the hinge joint, which is hinged to the main structure. The hinge joint is a single-axis hinge joint, controlling the diagonal brace to rotate only in one plane. The signal receiver is connected to the building disaster prevention and early warning system. Upon receiving a disaster prevention and early warning command, it controls the booster to open or close the diagonal brace via a control wire. When the diagonal brace is in the closed state, it is retracted to the side of the main structure and protected by the protective cover. When the diagonal brace is in the working state, the diagonal braces are automatically fastened and fixed by the fastening joints at their ends, forming structural support, thereby enhancing the load-bearing capacity and rigidity of the building structure and jointly resisting external disasters.

[0005] In the technical solution of this invention, the structural support device has a simple structure and a wide range of applications. It can be installed between openings or nodes in walls, columns, beams, and slabs of various building structures, and the installation of the structural support has very little impact on the functional layout and usable space of the building. The structural support device mainly relies on the diagonal braces hinged to the main structure to participate in the force-bearing process, which can give full play to the mechanical properties of the diagonal brace material under compression and tension. The hinge joint adopts a single-axis hinge joint to control the diagonal brace from moving out of the plane during the force-bearing process, ensuring the stability of the structural support. The diagonal brace fastening joint adopts a sawtooth surface, a corrugated surface, or a keyway surface for fastening, which can effectively transmit the tensile and compressive stress between the diagonal braces and ensure that the diagonal brace fully participates in the structural force-bearing process. The booster is embedded in the main structure or installed on the surface of the main structure. Its push rod is hinged to the diagonal brace. When the diagonal brace is opened, the booster, the diagonal brace, and the main structure form a stable triangular force-bearing structure, which further ensures the stable fastening of the diagonal brace.

[0006] Furthermore, in the technical solution of this invention, the operation of the structural support device is controlled by the building disaster prevention and early warning system. During the period when the signal receiver does not receive a disaster prevention and early warning instruction, the diagonal brace is always in a closed state and is retracted to the side of the main structure, which will not affect the lighting of windows and curtain walls, passage through doorways, or use of functional areas. When the signal receiver receives a disaster prevention and early warning instruction, the diagonal brace can be quickly opened by activating the booster to complete the automatic fastening and fixing, forming a structural support, which effectively solves the problem that it is difficult for humans to complete the judgment and opening in a short time during a disaster.

[0007] Furthermore, in the technical solution of this invention, the diagonal brace is protected by a protective cover, which not only facilitates the daily maintenance of the diagonal brace, but also prevents the diagonal brace from being exposed and affecting the aesthetics of the building. During the process of the booster opening the diagonal brace, the diagonal brace pushes the movable plate of the protective cover to open automatically outward. After the diagonal brace is retracted, the movable plate of the protective cover closes automatically under the action of the spring hinge, avoiding the cumbersome procedure of opening manually or with power equipment, and improving the reliability of the structural support device.

[0018] The technical solutions of the present invention will be further described below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] The present invention is as follows Figure 1-8As shown. A structural support device based on a building disaster prevention and early warning system includes a diagonal brace 1, a protective cover 2, a booster 3, and a signal receiver 4. The diagonal brace 1 is mainly composed of a strut 5, a hinge joint 6, and a fastening joint 7, and is hinged to the main structure 8 through the hinge joint 6. The components of the diagonal brace 1 can be made of steel, and the size and strength are determined according to the magnitude of the force. The strut 5 can be made as a solid or hollow rod. The hinge joint 6 can be connected to the main structure 8 by pre-embedding, welding, or bolting. The fastening form of the fastening joint 7 can be a sawtooth surface, a corrugated surface, or a keyway surface. The fastening surface can also be treated by sanding, knurling, or embedding anti-slip pads to increase friction. The signal receiver 4 is connected to the building disaster prevention and early warning system. Upon receiving a disaster prevention and early warning command, it controls the booster 3 to open or close the diagonal brace 1 via the control wire 9. The booster 3 can be a hydraulic or mechanical booster, which can be embedded in the main structure 8 or installed on the surface of the main structure 8. The signal receiver 4 and the building disaster prevention and early warning system can be connected wirelessly or via wire. When the diagonal brace 1 is closed, it is retracted to the side of the main structure 8 component and protected by the protective cover 2. When the diagonal brace 1 is open, the diagonal brace 1 is automatically fastened and fixed by the fastener 7 to form a structural support. The diagonal brace 1 can be retracted to the side of the main structure 8 wall, column, or beam component. The fixing plate 10 of the protective cover 2 can be connected to the main structure 8 by bolts or welding. The movable plate 11 is connected to the fixing plate 10 by spring hinge 12. The material and color of the protective cover 2 can be freely selected according to the architectural decoration style.

[0020] Appendix Figure 1-4 This is an example of a structural support device. For example... Figure 1-2 As shown, the structural support devices are arranged in a double-row, crisscross pattern within the main structure 8. One diagonal brace 1 is installed at each of the four corners of the structural opening. Each diagonal brace 1 has a corresponding booster 3 embedded inside the wall (column) of the main structure 8. A signal receiver 4 is installed on one side of the wall (column) of the main structure 8 to centrally control the operation of the two sets of diagonal braces 1. A protective cover 2 is installed on the side of the wall (column) of the main structure 8. When the diagonal brace 1 is not in operation, it is retracted to the side of the wall (column) of the main structure 8. When the diagonal brace 1 is in operation, the booster 3 pushes the diagonal brace 1 to the left or right to open it, and after locking, forms two sets of crisscross structural supports within the opening of the main structure 8. Figure 3-4 As shown, in specific building cases, this structural support device can be evenly installed in the beams, columns, or shear wall openings of each floor. By improving the overall bearing capacity and stiffness redundancy of the building structure, it can reduce the risk of component failure under severe conditions such as explosions, earthquakes, or typhoons. It can also be installed in the weak structural area 13 within the floor. By adjusting the in-plane structural stiffness distribution in a targeted manner, it can control the torsional failure of the building structure under horizontal loads such as earthquakes or typhoons, thereby reducing structural deformation and cracking.

[0021] Appendix Figure 5-8This is another embodiment of the structural support device. For example... Figure 5-6 As shown, the structural support devices are arranged continuously side-by-side within the main structure 8. One diagonal brace 1 is installed at the lower left and lower right corners of the structural opening, and two diagonal braces 1 are installed along the middle of the upper edge of the structural opening. Each diagonal brace 1 has a corresponding booster 3 installed on the surface of the horizontal beam of the main structure 8. A signal receiver 4 is installed on one side of the column of the main structure 8 to centrally control the operation of the two sets of diagonal braces 1. A protective cover 2 is installed on the top or bottom of the horizontal beam of the main structure 8. When the diagonal brace 1 is not in operation, it is retracted to the top or bottom of the horizontal beam of the main structure 8. When the diagonal brace 1 is in operation, the booster 3 pushes the diagonal brace 1 downwards or upwards to open it, and after locking, two sets of continuous side-by-side structural supports are formed within the opening of the main structure 8. Figure 7-8 As shown, in a specific building case, the structural support device can be installed in the structurally weak layer 14 with a large span. By adjusting the vertical stiffness distribution of the structure in a targeted manner, it can control the inter-story shear failure of the building structure under horizontal loads such as earthquakes or typhoons, thereby reducing structural deformation and cracking.

[0022] The installation steps of the structural support device are as follows: (1) Position the pre-embedded hinge joint 6 and booster 3 during the construction of the main structure 8, or position and weld or bolt the hinge joint 6 and booster 3 after the construction of the main structure 8 is completed; (2) Connect one end of the strut 5 to the fastener 7 and the other end to the hinge joint 6. After the diagonal brace 1 is installed, the strut 5 and the push rod of the booster 3 are hinged; (3) Install the signal receiver 4 on the side of the wall (column) of the main structure 8 and connect the signal receiver 4 to the building disaster prevention and early warning system. Lay the control wire 9 from the signal receiver 4 and connect it to the booster 3; (4) Install the protective cover 2 on the side of the main structure 8 component; (5) Debug and run the structural support device.
