Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a reinforcement structure for large-span buildings. Background Technology

[0002] As long as a building has been in use, the performance of its structural materials deteriorates, such as concrete carbonization and steel corrosion, leading to a reduction in the building's load-bearing capacity. After natural disasters such as earthquakes, windstorms, and fires, the building structure may suffer damage such as cracks and deformation, affecting structural safety. There are many ways to reinforce large-span buildings, such as thin-shell reinforcement. In existing thin-shell reinforcement methods, mounting components are installed on the building walls, with the bottom outer ring of the thin shell installed on top of the mounting components. Large-span building structures cause the mounting components to bear large loads, and the bottom of the mounting components usually needs to be reinforced with a supporting structure to improve stability. However, existing buildings are usually located below the walls of existing buildings, making it inconvenient to install a supporting structure. Utility Model Content

[0003] The problem this utility model aims to solve is that existing houses often have buildings below their walls, making it inconvenient to install supporting structures.

[0004] To address the aforementioned technical problems, this utility model provides a large-span building reinforcement structure, comprising multiple trusses connected end-to-end, with one side of each truss mounted on a building wall. A bottom support structure is provided at the bottom of the trusses, comprising prestressed tendons, two mounting rods, and two mounting columns. One end of each mounting rod is positioned on either side of the bottom of the truss, and one end of each prestressed tendon is simultaneously mounted to one end of a mounting rod and the bottom of the truss. The two mounting columns are positioned on the ground, with the mounting rods rotatably mounted on the top of the mounting columns. A thin-shell outer ring is provided at the top of each truss, and one end of a support rod is provided on one side of each truss, with the other end of the support rod bolted to the interior of the building.

[0005] Preferably, the top of the truss is an arc-shaped structure, the interior of the truss is provided with a steel frame, and the exterior of the steel frame is provided with concrete.

[0006] Preferably, the top of the mounting column has a rotating groove, and the bottom of the mounting rod is bolted to the top of the rotating groove.

[0007] Preferably, one end of the support rod extends obliquely into the interior of the house and is provided with a fixing plate, which is bolted to the interior of the house.

[0008] Preferably, the number of support rods is two and they are symmetrically arranged on both sides of the truss.

[0009] Preferably, the truss has a hollow structure inside.

[0010] Preferably, one end of the prestressed tendon is installed with a support column via an anchor, and the other end of the support column is connected to the bottom of the truss via bolts.

[0011] Preferably, the number of support columns is three and they are arranged symmetrically about the middle of the truss.

[0012] Preferably, the thin shell has a mounting hole at the center of its top.

[0013] Preferably, a skylight is provided inside the mounting hole.

[0014] Compared with the prior art, this utility model provides a large-span building reinforcement structure, which has the following beneficial effects:

[0015] 1. This utility model increases the load-bearing capacity of the middle section of the truss by setting prestressed tendons, two mounting rods, and two mounting columns. The two ends of the prestressed tendons are installed at both ends of the bottom of the truss. The mounting rods are rotatably mounted at the top of the mounting columns, allowing the mounting rods to extend from the building below the wall to the bottom of the truss. This allows the two ends of the prestressed tendons to be installed at both the mounting rods and the bottom of the truss, increasing the load-bearing capacity of the bottom of the truss and enabling the truss to better withstand the loads generated by large-span buildings. By setting a thin shell, the bottom outer ring of which is installed at the top of the truss, the load borne by the building is distributed, effectively improving the building's crack resistance and damage resistance, and enhancing the overall strength of the structure. By setting support rods, which are installed inside the building, the interior of the building is connected to the truss, increasing the overall structural strength of the building and improving the stability of the connection between the truss and the building. This solves the problem that existing buildings usually have buildings below the walls, making it inconvenient to set up support structures. Attached Figure Description

[0023] This utility model relates to a reinforcement structure for large-span buildings, such as... Figure 1-6 As shown, the structure includes multiple trusses 1 connected end-to-end, with one side of each truss 1 attached to a building wall. Each truss 1 has a bottom support structure comprising prestressed tendons 2, two mounting rods 3, and two mounting columns 4. One end of each mounting rod 3 is positioned on either side of the bottom of the truss 1, and one end of each prestressed tendon 2 is simultaneously attached to one end of a mounting rod 3 and the bottom of the truss 1. The two mounting columns 4 are positioned on the ground, with the mounting rods 3 rotatably mounted on top of each column 4. A thin shell 5 forms the bottom outer ring of each truss 1. One end of each truss 1 has a support rod 6 attached to one side, with the other end bolted to the interior of the building. By connecting multiple trusses 1 end-to-end, a single unit is formed. The trusses 1 are installed to the building wall, serving as the fixing structure for the bottom outer ring of the thin shell 5. The prestressed tendons 2, two mounting rods 3, and two mounting columns 4 are connected at both ends to the trusses 1. The bottom ends are installed to increase the load-bearing capacity of the middle of the truss 1. The bottom of the mounting rod 3 is rotated and set on the top of the mounting column 4, which facilitates the rotation of the mounting rod 3 at the top of the mounting column 4. This allows the mounting rod 3 to extend from the building below the wall to the bottom of the truss 1. The two ends of the prestressing tendon 2 are simultaneously installed with the mounting rod 3 and the bottom of the truss 1, increasing the support performance of the bottom of the truss 1 and making it easier for the truss 1 to bear the load generated by the large-span building. By setting the thin shell 5, the bottom outer ring of the thin shell 5 is installed with the top of the truss 1 to share the load borne by the building, effectively improving the building's crack resistance and damage resistance, and enhancing the overall strength of the structure. By setting the support rod 6, which is installed with the interior of the building, the interior of the building is connected to the truss 1, increasing the overall structural strength of the building and improving the stability of the connection between the truss 1 and the building. This solves the problem that existing buildings usually have buildings below the walls, making it inconvenient to set up a support structure.

[0024] In this embodiment of the utility model, the top of the truss 1 is an arc-shaped structure, the truss 1 is provided with a steel frame 7 inside, and the outside of the steel frame 7 is provided with concrete.

[0025] In this embodiment of the utility model, the top of the mounting column 4 has a rotating groove 8, and the bottom of the mounting rod 3 is bolted to the top of the rotating groove 8. By setting the rotating groove 8, the bottom of the mounting rod 3 rotates at the top of the rotating groove 8, which facilitates the installation of the mounting rod 3 from the top of the building to the bottom of the truss 1. The bolted connection between the mounting rod 3 and the rotating groove 8 facilitates the fixing of the mounting rod 3 and the rotating groove 8, thereby improving the stability of the installation of the mounting rod 3 and the mounting column 4.

[0026] In this embodiment of the utility model, one end of the support rod 6 extends obliquely into the interior of the house and is provided with a fixing plate 9. The fixing plate 9 is bolted to the interior of the house. By setting the fixing plate 9 and bolting it to the interior of the house, the fixing plate 9 is firmly fixed to the interior of the house, thereby improving the overall structural strength of the house. Furthermore, by extending obliquely into the interior of the house, the support rod 6 forms a triangular structure, thereby improving the strength of the connection structure between the support rod 6 and the truss 1.

[0027] In this embodiment of the utility model, there are two support rods 6, which are symmetrically arranged on both sides of the truss 1. By setting the number of support rods 6 to two and symmetrically arranged on both sides of the truss 1, the stability of the connection between the truss 1 and the support rods 6 is improved.

[0028] In an embodiment of this utility model, the truss 1 has a hollow structure inside. By setting the truss 1 to have a hollow structure inside, the self-weight of the truss 1 is optimized, and the stress performance of the truss 1 is optimized.

[0029] In this embodiment of the utility model, one end of a support column 10 is installed on the upper end of the prestressed tendon 2 through an anchor, and the other end of the support column 10 is connected to the bottom of the truss 1 by bolts. By setting the support column 10, the two ends of the support column 10 are connected to the truss 1 and the prestressed tendon 2 respectively, and the bottom of the truss 1 is supported, which facilitates the improvement of the truss 1's ability to bear vertical loads and improves the overall stability of the truss 1 structure.

[0030] In this embodiment of the utility model, the number of support columns 10 is three and they are symmetrically arranged about the middle of the truss 1. By setting the number of support columns 10 to three and symmetrically arranged about the middle of the truss 1, it is convenient to evenly transfer the load.

[0031] In an embodiment of this utility model, a mounting hole 11 is provided in the middle of the top of the thin shell 5. By providing the mounting hole 11, it is convenient to install a skylight 12 on the top of the thin shell 5.

[0032] In an embodiment of this utility model, a light-transmitting pavilion 12 is provided inside the mounting hole 11. By providing the light-transmitting pavilion 12, it is convenient to introduce sunlight into the interior of the thin shell 5, thereby improving the lighting and light transmission effect inside the thin shell 5. The light-transmitting pavilion 12 can adjust the light entering the room through its light-adjusting function.

[0033] In use, firstly, multiple trusses 1 are connected end to end on the building wall. Then, the mounting columns 4 are installed on the ground. The mounting rods 3 are rotated in the rotating groove 8, so that the mounting rods 3 are rotated to the top of the building and installed at both ends of the bottom of the trusses 1. The two ends of the prestressing tendons 2 are installed simultaneously with the trusses 1 and the mounting rods 3 to increase the support performance of the bottom of the trusses 1. Then, three support columns 10 are symmetrically arranged about the middle of the trusses 1 at the bottom of the trusses 1 and the top of the prestressing tendons 2. The bottom outer ring of the thin shell 5 is installed with the top of the trusses 1 to share the load borne by the building, effectively improving the building's crack resistance and damage resistance, and enhancing the overall strength of the structure. The skylight 12 is installed inside the mounting hole 11 to facilitate the introduction of sunlight into the thin shell 5, improving the lighting and illumination effect inside the thin shell 5. The support rods 6 pass through the building and enter the building, so that the fixing plate 9 is bolted to the building interior.
