A reinforcing structure for an existing building

Abstract

This application relates to the field of structural reinforcement technology and discloses a reinforcement structure for existing buildings, including a building body, columns, beams, column reinforcement components, and beam reinforcement components. This application achieves rapid assembly by using angle steel and a horizontal connecting plate body connected by a first U-shaped block engaging a first U-shaped groove. Then, a first connecting plate bolt passes through the first horizontal connecting plate connection hole and a pre-drilled hole for locking. A first structural adhesive layer fills the gaps, ensuring a tight connection and stable reinforcement of the column reinforcement components. After the insert of the beam reinforcement horizontal plate is inserted into the slot of the vertical connecting plate body, a second connecting plate bolt passes through the second vertical connecting plate connection hole and locks with the first vertical connecting plate connection hole. A second U-shaped block at the top of the vertical connecting plate body engages with the second U-shaped groove of the beam reinforcement vertical plate, and a third connecting plate bolt passes through the third vertical connecting plate connection hole for locking. Combined with the second structural adhesive layer, this facilitates the assembly of the beam reinforcement components and enhances the connection strength of the beams.

Description

Technical Field

[0001] This application relates to the technical field of reinforcement structures, and in particular to a reinforcement structure for existing buildings. Background Technology

[0002] In the field of structural reinforcement of existing buildings, traditional reinforcement methods have shortcomings when reinforcing columns and beams within the building structure. Their connection reliability is poor, and some reinforcement structures only use simple bolt connections, resulting in insufficient stress transfer. Under long-term stress or external forces, these connections are prone to loosening, thus affecting the structural stability of the reinforced columns and beams and failing to fully meet the structural safety and durability requirements of reinforced existing buildings. Therefore, there is an urgent need for a simple-to-assemble and reliable reinforcement structure for existing buildings to improve these problems. Utility Model Content

[0003] To address the aforementioned problems, this application provides a reinforcement structure for existing buildings.

[0004] This application provides a reinforcement structure for existing buildings, employing the following technical solution: A reinforcement structure for an existing building includes a building body, columns, beams, column reinforcement components, and beam reinforcement components. The column reinforcement components include four angle steels and multiple transverse connecting plate bodies. Each angle steel has multiple first convex grooves on both sides of its outer surface. Each first convex groove has two first transverse connecting plate connection holes on its inner wall. Each transverse connecting plate body has a first convex block fixedly connected to both ends. The first convex blocks are engaged in the inner wall of the first convex groove.

[0005] The beam reinforcement assembly includes a beam reinforcement horizontal plate and multiple vertical gusset plates. Multiple inserts are fixedly connected to both sides of the upper surface of the beam reinforcement horizontal plate. Each insert has a first vertical gusset plate connection hole inside. Each vertical gusset plate has a slot on its bottom surface and a second vertical gusset plate connection hole on its inner wall. The inserts are inserted into the inner wall of the slot, with the position of the second vertical gusset plate connection hole corresponding to the position of the first vertical gusset plate connection hole. A second convex block is fixedly connected to the top of each vertical gusset plate, and a third vertical gusset plate connection hole is opened inside each second convex block. A beam reinforcement vertical plate is installed on the top of the outer surface of the beam. Multiple second convex grooves are opened on the inner side of the beam reinforcement vertical plate, and the second convex blocks are engaged in the inner wall of the second convex grooves.

[0006] By adopting the above technical solution, the angle steel and the horizontal lacing plate body are engaged by the first convex block and the first convex groove, which enables the column reinforcement component to quickly complete the assembly of the components when reinforcing the columns of the building body. It also makes the connection between the components tighter and improves the structural stability of the column after reinforcement. The beam reinforcement horizontal plate, the vertical lacing plate body and the beam reinforcement vertical plate are connected by the insertion of the plug and the slot, and the second convex block and the second convex groove. This makes the beam reinforcement component easier to reinforce the horizontal beam and enhances the connection strength between the horizontal beam and the beam reinforcement component. The overall structure does not require complicated procedures during assembly. It is suitable for the on-site operation requirements of existing building reinforcement and ensures that the reinforced structure has good stress performance. It effectively improves the problems of cumbersome assembly and poor connection reliability of traditional reinforcement structures.

[0007] Optionally, the column is fixedly connected to the interior of the building body, and the beam is fixedly connected to the top of the column.

[0008] By adopting the above technical solutions, the columns and the building body, as well as the beams and columns, form a stable original building structure, providing a foundation for the installation of subsequent components.

[0009] Optionally, each angle steel has multiple column connecting bolts installed on its inner wall, and the angle steel is fixedly connected to the corner of the column by the column connecting bolts.

[0010] By adopting the above technical solution, the angle steel is fixed to the corner of the column using column connecting bolts, so that the angle steel and the column are connected first, which facilitates the subsequent reinforcement work.

[0011] Optionally, each of the first convex-shaped blocks has a reserved hole at both ends, and a first connecting bolt for the first lacing plate is installed on the inner wall of each reserved hole. The other end of the first connecting bolt is installed in the inner wall of the corresponding first transverse connecting hole for the first lacing plate.

[0012] By adopting the above technical solution, the first connecting bolt of the first connecting plate passes through the reserved hole of the first convex block and the first transverse connecting plate of the angle steel, thereby locking the transverse connecting plate body and the angle steel together and enhancing the connection firmness.

[0013] Optionally, a first structural adhesive layer is applied between the transverse gusset plate body and the angle steel, and a second structural adhesive layer is applied between the beam reinforcement horizontal plate, the vertical gusset plate body and the beam reinforcement vertical plate.

[0014] By adopting the above technical solution, the first structural adhesive layer fills the gap between the horizontal gusset plate body and the angle steel, and the second structural adhesive layer fills the gap between the beam reinforcement horizontal plate, the vertical gusset plate body and the beam reinforcement vertical plate, thereby improving the bonding force between the reinforcement component and the original structure and between the components, which is conducive to stress transfer.

[0015] Optionally, the inner wall of the beam-reinforcing horizontal plate is equipped with a plurality of first beam connecting bolts, and the beam-reinforcing horizontal plate is fixedly connected to the bottom surface of the horizontal beam by the first beam connecting bolts. The interior of the beam-reinforcing vertical plate is equipped with evenly distributed second beam connecting bolts, and the beam-reinforcing vertical plate is fixedly connected to the outer surface of the horizontal beam by the second beam connecting bolts.

[0016] By adopting the above technical solution, the beam reinforcement horizontal plate is fixed to the bottom surface of the beam with the first beam connecting bolt, and the beam reinforcement vertical plate is fixed to the outer surface of the beam with the second beam connecting bolt, thus ensuring the stability of the connection between the beam reinforcement horizontal plate and the beam reinforcement vertical plate and the beam.

[0017] Optionally, a second connecting bolt is installed on the inner wall of each of the second vertical connecting holes, and the other end of the second connecting bolt is installed in the inner wall of the first vertical connecting hole.

[0018] By adopting the above technical solution, the vertical lacing plate body and the beam reinforcement horizontal plate are locked together by passing the second vertical lacing plate connecting bolt through the second vertical lacing plate connecting hole of the vertical lacing plate body and the first vertical lacing plate connecting hole of the insert block, thereby strengthening the connection stability of the beam reinforcement part.

[0019] Optionally, a third connecting bolt is installed on the inner wall of each of the second convex grooves, and the other end of the third connecting bolt is installed in the inner wall of the third vertical connecting hole.

[0020] By adopting the above technical solution, the third connecting bolt passes through the second convex groove of the beam reinforcement vertical plate and the third vertical connecting hole of the second convex block of the vertical connecting plate body, thereby locking the vertical connecting plate body and the beam reinforcement vertical plate together, further improving the overall firmness of the beam reinforcement part.

[0021] In summary, this application includes at least one of the following beneficial effects: 1. Replacing the traditional single bolt connection, it can effectively limit the relative displacement between components, reduce the risk of loosening, and, together with bolt locking and structural adhesive filling, not only strengthens the rigid connection between components, but also fills the gaps and transfers stress through the adhesive layer, making the overall stress more uniform and improving the durability and safety of the reinforced columns and beams. 2. Bolt connections are used only as the final locking step, and the hole positions are all pre-set and correspond. The assembly process is clear, which can effectively shorten the construction cycle of existing building reinforcement and reduce the impact on the normal use of the building.

The columns 2 are fixedly connected to the interior of the building body 1, and the beams 3 are fixedly connected to the top of the columns 2, so that the columns 2 and the building body 1, and the beams 3 and the columns 2 form a stable original building structure, providing a foundation for the installation of subsequent components.

[0026] Reference Figure 2 , Figure 3The column reinforcement component 4 includes four angle steels 401 and multiple transverse gusset plates 405. Each angle steel 401 has multiple column connecting bolts 402 installed on its inner wall. The angle steels 401 are fixedly connected to the corners of the column 2 by the column connecting bolts 402. The angle steels 401 are fixed to the corners of the column 2 by the column connecting bolts 402, so that the angle steels 401 and the column 2 are connected firstly, which facilitates the subsequent reinforcement work.

A first structural adhesive layer 409 is applied between the transverse connecting plate body 405 and the angle steel 401. The first structural adhesive layer 409 fills the gap between the transverse connecting plate body 405 and the angle steel 401, thereby improving the stability of the connection between the angle steel 401 and the transverse connecting plate body 405.

Each insert 503 has a first vertical gusset plate connection hole 504 inside. Each vertical gusset plate body 505 has a slot 506 on its bottom surface. Each slot 506 has a second vertical gusset plate connection hole 507 on its inner wall. The inserts 503 are inserted into the inner wall of the slot 506, and the position of the second vertical gusset plate connection hole 507 corresponds to the position of the first vertical gusset plate connection hole 504.

To ensure the stability of the connection between the horizontal plate 501 and the beam reinforcement vertical plate 511 and the horizontal beam 3, a second lacing plate connecting bolt 508 is installed on the inner wall of each second vertical lacing plate connecting hole 507. The other end of the second lacing plate connecting bolt 508 is installed in the inner wall of the first vertical lacing plate connecting hole 504. By passing the second lacing plate connecting bolt 508 through the second vertical lacing plate connecting hole 507 of the vertical lacing plate body 505 and the first vertical lacing plate connecting hole 504 of the insert block 503, the vertical lacing plate body 505 and the beam reinforcement horizontal plate 501 are locked together, thereby strengthening the connection stability of the beam reinforcement part.

[0031] Reference Figure 5 Each second convex groove 512 has a third connecting bolt 514 installed on its inner wall. The other end of the third connecting bolt 514 is installed in the inner wall of the third vertical connecting hole 510. By passing the third connecting bolt 514 through the second convex groove 512 of the beam reinforcement vertical plate 511 and the third vertical connecting hole 510 of the second convex block 509 of the vertical connecting plate body 505, the vertical connecting plate body 505 and the beam reinforcement vertical plate 511 are locked together, further improving the overall firmness of the beam reinforcement part.

[0032] Reference Figure 4 , Figure 5A second structural adhesive layer 515 is applied between the beam reinforcement horizontal plate 501, the vertical gusset plate body 505 and the beam reinforcement vertical plate 511. The second structural adhesive layer 515 fills the gap between the beam reinforcement horizontal plate 501, the vertical gusset plate body 505 and the beam reinforcement vertical plate 511, improves the adhesion between the reinforcement component and the original structure and between the components, and facilitates stress transfer.

[0033] The implementation principle of this application embodiment is as follows: the angle steel 401 is pre-fixed to the corner of the column 2 by the column connecting bolt 402, and then the first convex blocks 406 at both ends of the transverse gusset plate body 405 are inserted into the first convex groove 403 on the outer surface of the angle steel 401 to achieve rapid positioning of the transverse gusset plate body 405 and the angle steel 401. Next, the first connecting bolt 408 passes through the reserved hole 407 on the first convex block 406 and the first transverse connecting hole 404 on the angle steel 401, locking the two together. At the same time, the first structural adhesive layer 409 fills the gap between the transverse connecting plate body 405 and the angle steel 401, improving the connection tightness and stress transmission effect, so that the column reinforcement component 4 can stably reinforce the column 2. Then, the beam reinforcement horizontal plate 501 is fixed to the bottom surface of the horizontal beam 3 by the first beam connecting bolt 502. Then, the slot 506 on the bottom surface of the vertical lacing plate body 505 is inserted into the insert block 503 on the beam reinforcement horizontal plate 501. The second lacing plate connecting bolt 508 passes through the second vertical lacing plate connecting hole 507 of the vertical lacing plate body 505 and the first vertical lacing plate connecting hole 504 of the insert block 503 to lock the vertical lacing plate body 505 to the beam reinforcement horizontal plate 501. Then, the beam reinforcement vertical plate 511 is fixed to the outer surface of the horizontal beam 3 by the second beam connecting bolt 513. At this time, the second convex-shaped block 509 at the top of the vertical lacing plate body 505 is inserted into the second convex-shaped groove 512 of the beam reinforcement vertical plate 511. The third lacing plate connecting bolt 514 passes through the third vertical lacing plate connecting hole 510 between the beam reinforcement vertical plate 511 and the second convex-shaped block 509. The vertical gusset plate body 505 and the beam reinforcement vertical plate 511 are further tightened, and the second structural adhesive layer 515 is filled in the gap between the beam reinforcement horizontal plate 501, the vertical gusset plate body 505 and the beam reinforcement vertical plate 511 to enhance the bonding force and stress transmission between components. In this way, the beam 3 and the column reinforcement component 4 achieve rapid assembly and ensure connection reliability through the synergy of snap-fit ​​positioning, bolt tightening and structural adhesive filling, so that the reinforced column 2 and beam 3 can be stably stressed, meeting the requirements of existing building reinforcement for structural safety and durability.
