Description

Technical Field

[0001] This application relates to the field of old building reinforcement technology, specifically a reinforcement structure for old buildings. Background Technology

[0002] In existing old buildings, it has been found that the supporting columns are the core load-bearing components, and their safety directly affects the overall stability of the building. In the reinforcement of supporting columns, it has been found that the external steel reinforcement method is usually used. By wrapping the supporting columns with steel plates or steel sections, the load-bearing capacity of the components is improved. However, during the construction of supporting columns, welding or drilling holes are required on the surface of the supporting columns. This reinforcement method will damage the components that originally needed to be reinforced. Utility Model Content

[0003] In view of the shortcomings of the prior art, this application provides a reinforcement structure for old buildings, which has the advantages of supporting the building without welding or drilling, eliminating the need for drilling on the original structure surface and reducing damage to the original components. It solves the problem found in the reinforcement structure of support columns that welding or drilling is required during construction, which can damage the components that originally need to be reinforced.

[0004] To achieve the above objectives, this application provides the following technical solution: a reinforcement structure for an old building, comprising a beam slab, with a support column fixedly connected to the bottom surface of the beam slab, and two steel plates (first and second) provided below the beam slab. Two square blocks are fixedly connected to the left and right sides of each steel plate (second). A square groove is formed on the opposite side of each steel plate (first), and the inner wall of each square groove is slidably connected to the outer surface of the corresponding square block. Two sliding grooves are formed inside each steel plate (first), and a sliding block is slidably connected to the inner wall of each sliding groove. Two pins are fixedly connected to the opposite side of each sliding block, and the outer surface of each pin slides against the inner wall of the corresponding square block. A bidirectional threaded rod is rotatably connected to the inner wall of each steel plate (first), and the outer surface of each bidirectional threaded rod is threadedly connected to the inner wall of the corresponding sliding block.

[0005] The above scheme achieves steel plate support for the building without welding or drilling, eliminating the need for drilling holes in the original structure. Steel plates one and two are installed below the beams and slabs. Square grooves are cut into the surface of steel plate one, and square blocks are installed on the left and right sides of steel plate two. The connection between the square grooves and the square blocks provides initial positioning of steel plates one and two. Then, rotating the corresponding double-threaded rod allows two sliding blocks on its surface to slide within the corresponding sliding grooves. These sliding blocks then move corresponding pins, connecting them to the square blocks, thus assembling steel plates one and two. At this point, the upper surfaces of steel plates one and two are in contact with the bottom surface of the beams and slabs, and the inner walls of steel plates one and two are in contact with the supporting columns. By supporting steel plates one and two, the supporting columns and beams and slabs are supported, eliminating the need for welding or drilling, thus reducing damage to the original components.

[0006] Furthermore, each of the steel plates 1 and 2 has a connector 1 fixedly connected to the side of each steel plate that is far apart from each other, and each connector 1 has an mounting component 1 rotatably connected to its inner wall.

[0007] The above scheme involves installing connector one on the opposite sides of steel plates one and two, thus achieving the installation of connector one. Connecting the mounting part one to the corresponding connector one is configured as a rotatable connection, thereby limiting the movement of connector one.

[0008] Furthermore, mounting plates arranged at equal intervals are provided below the beam plate, and a connector is fixedly connected to the upper surface of each mounting plate.

[0009] The above method involves placing the mounting plate below the beam and fixing it to the ground with bolts to achieve the installation of the mounting plate. Connector 2 is installed on the upper surface of the mounting plate as a fixed connection. The installation of connector 2 is achieved by fixing the mounting plate to the ground.

[0010] Furthermore, each of the second connectors is rotatably connected to a second mounting component, and each of the second mounting components is fixedly connected to a fixing rod on its upper surface.

[0011] With the above scheme, the second mounting part is installed on the inner wall of the corresponding second connecting part, and is set as a rotatable connection to limit the position of the second mounting part. The fixing rod is installed on the upper surface of the corresponding second mounting part. Through the connection between the second connecting part and the second mounting part, the angle of the fixing rod can be adjusted.

[0012] Furthermore, a bevel gear is rotatably connected to the inner wall of each of the fixed rods, and a limit groove is formed on the upper surface of each of the fixed rods.

[0013] The above scheme involves installing a bevel gear on the inner wall of the corresponding fixed rod, setting it as a rotatable connection, and opening a limiting groove on the upper surface of the corresponding fixed rod to achieve positioning of the limiting groove.

[0014] Furthermore, each of the limiting grooves has a sliding rod slidably connected to its inner wall, and the top end of each sliding rod is fixedly connected to the bottom surface of the corresponding mounting component.

[0015] The above method involves installing the sliding rod on the inner wall of the corresponding limiting groove, setting it as a sliding connection. The sliding rod can be limited by the contour of the limiting groove, and the top of the sliding rod is connected to the corresponding mounting part.

[0016] Furthermore, each of the first bevel gears has a second bevel gear meshing on its outer surface, and each second bevel gear has an adjusting screw fixedly connected to its inner wall.

[0017] In the above scheme, bevel gear two is placed on the side of bevel gear one, and bevel gear one and bevel gear two are meshed. By rotating bevel gear one, bevel gear two can be rotated. The adjusting screw is fixed to bevel gear two, and by rotating bevel gear two, the corresponding adjusting screw can be rotated.

[0018] Furthermore, the outer surface of each adjusting screw is threadedly connected to the inner wall of the corresponding sliding rod, and the bottom end of each adjusting screw is rotatably connected to the inner wall of the corresponding fixed rod.

[0019] The above scheme connects the adjusting screw to the corresponding sliding rod in a threaded connection. By adjusting the rotation of the adjusting screw, the sliding rod can slide on the inner wall of the limiting groove, making the lengths of the sliding rod and the fixed rod adjustable. The fixed rod and the adjusting screw are connected by a rotational connection to limit the adjustment screw, so that the sliding rod can move stably when the adjusting screw rotates.

[0020] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0021] This reinforcement structure for old buildings uses components such as square blocks, sliding blocks, pins, and double-threaded rods. The square blocks are connected to square slots to initially position steel plates one and two. Then, rotating the corresponding double-threaded rod causes the sliding block to move the corresponding pin. Through the connection between the pin and the square block, steel plates one and two are assembled. At this point, the upper surfaces of steel plates one and two are in contact with the bottom surface of the beam, and the inner walls of steel plates one and two are in contact with the supporting columns. By supporting steel plates one and two, the supporting columns and beams are supported, achieving reinforcement without welding or drilling. The building's support eliminates the need for drilling holes in the original structure, reducing damage to the original components. Rotating the corresponding bevel gear one causes bevel gear two to rotate, which in turn drives the adjusting screw to rotate, allowing the sliding rod to slide within the limiting groove. After adjusting the lengths of the fixed rod and the sliding rod, the mounting plate is fixed to the ground by rotating connector one and mounting piece one and connector two and mounting piece two. The angle support of the fixed rod and the sliding rod forms a stable triangular support, which tightens steel plate one and steel plate two, enabling the device to improve support stability by providing four-way support to the support column.

The mounting piece 12 is connected to the corresponding connector 11, which is set as a rotatable connection, thus realizing the limiting of the connector 11.

[0032] Please see Figure 2 , Figure 3 and Figure 4 Below the beam 1, there are mounting plates 14 arranged at equal intervals. Each mounting plate 14 has a connector 2 15 fixedly connected to its upper surface. The mounting plates 14 are placed below the beam 1 and fixed to the ground with bolts to achieve the installation of the mounting plates 14. The connector 2 15 is installed on the upper surface of the mounting plates 14 to form a fixed connection. The installation of the connector 2 15 is achieved by fixing the mounting plates 14 to the ground.

Through the connection between the connector 2 15 and the mounting part 2 16, the angle of the fixing rod 17 can be adjusted.

[0034] Please see Figure 4 Each fixed rod 17 has a bevel gear 19 rotatably connected to its inner wall, and a limiting groove 18 is formed on the upper surface of each fixed rod 17. The bevel gear 19 is installed on the inner wall of the corresponding fixed rod 17 to form a rotatable connection, and the limiting groove 18 is formed on the upper surface of the corresponding fixed rod 17 to achieve positioning of the limiting groove 18.

[0035] Please see Figure 1 , Figure 2 and Figure 4 Each limiting groove 18 has a sliding rod 13 slidably connected to its inner wall. The top of each sliding rod 13 is fixedly connected to the bottom surface of the corresponding mounting part 12. The sliding rod 13 is installed on the inner wall of the corresponding limiting groove 18 and is set as a sliding connection.

The adjusting screw 21 and the corresponding sliding rod 13 are connected by a threaded connection. By adjusting the rotation of the adjusting screw 21, the sliding rod 13 can slide on the inner wall of the limiting groove 18, making the lengths of the sliding rod 13 and the fixed rod 17 adjustable.

[0038] This embodiment describes a reinforcement structure for an old building. By using components such as a square block 5, a sliding block 8, a pin 9, and a bidirectional threaded rod 10, the square block 5 is connected to a square groove 6, achieving initial positioning of steel plate 3 and steel plate 4. Then, rotating the corresponding bidirectional threaded rod 10 causes the sliding block 8 to move the corresponding pin 9. Through the connection between the pin 9 and the square block 5, the steel plate 3 and steel plate 4 are assembled. At this point, the upper surfaces of steel plate 3 and steel plate 4 are in contact with the bottom surface of the beam slab 1, and the inner walls of steel plate 3 and steel plate 4 are in contact with the support column 2. By supporting steel plate 3 and steel plate 4, the support column 2 and beam slab 1 are supported, enabling reinforcement of the building without welding or drilling. The support structure eliminates the need for drilling holes in the original structure, reducing damage to the original components. Rotating the corresponding bevel gear 19 causes bevel gear 20 to rotate, which in turn drives the adjusting screw 21 to rotate, causing the sliding rod 13 to slide within the limiting groove 18. After adjusting the lengths of the fixed rod 17 and the sliding rod 13, the mounting plate 14 is fixed to the ground by rotating the connector 11 and mounting piece 12, and the connector 25 and mounting piece 26. The angle support of the fixed rod 17 and the sliding rod 13 forms a stable triangular support, which tightens the steel plate 13 and the steel plate 24, enabling the device to improve the stability of the support column 2 by providing four-way support.

[0039] It should be noted that beam 1 is the supporting beam above support column 2, and support column 2 is a column inside the building used to support the main beam and important parts.

[0040] The working principle of the above embodiments is as follows:

[0041] First, by connecting the square block 5 to the square groove 6, the steel plate 3 and the steel plate 4 are initially positioned. Then, rotating the corresponding bidirectional threaded rod 10 causes the sliding block 8 to move the corresponding pin 9 within the sliding groove 7. The connection between the pin 9 and the square block 5 completes the assembly of the steel plate 3 and the steel plate 4. At this point, the upper surfaces of the steel plate 3 and the steel plate 4 are in contact with the bottom surface of the beam plate 1, and the inner walls of the steel plate 3 and the steel plate 4 are in contact with the support column 2. By supporting the steel plate 3 and the steel plate 4, the support column 2 and the beam plate 1 are supported. Rotating the corresponding bevel gear 19 causes the bevel gear 20 to rotate, which in turn drives the adjusting screw 21 to rotate. The movement causes the sliding rod 13 to slide within the limiting groove 18. After adjusting the lengths of the fixed rod 17 and the sliding rod 13, the mounting plate 14 is fixed to the ground by the rotation of the connecting piece 11 and the mounting piece 12, and by the rotation of the connecting piece 2 15 and the mounting piece 2 16. The fixed rod 17 and the sliding rod 13 provide angular support, forming a stable triangular support that holds the steel plate 1 3 and the steel plate 2 4 together. This allows the device to support the building without welding or drilling, eliminating the need for drilling holes in the original structure and reducing damage to the original components. Furthermore, the device enhances the stability of the support by providing four-way support to the support column 2.
