Description

Technical Field

[0001] This utility model belongs to the field of beam and column reinforcement technology, and more specifically, it relates to a beam and column reinforcement structure for the renovation of old houses. Background Technology

[0002] The core function of beam and column reinforcement structures in the renovation of old houses is to repair the damage and defects of old beams and columns, improve their load-bearing capacity and stability, ensure the safety and reliability of the renovated house structure, adapt to new usage requirements, and extend the overall service life of the house. Existing beam and column reinforcement structures for the renovation of old houses achieve reinforcement by adding angle steel at the beam and column connection. However, when installing angle steel, holes need to be drilled in the beams and columns, which can easily cause secondary structural damage to the already fragile old beams and columns. Therefore, a beam and column reinforcement structure for the renovation of old houses is proposed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a beam-column reinforcement structure for the renovation of old houses. In use, holes are drilled in the floor slab and wall where the beam and column are located. After drilling, the threaded end of the tie rod is passed through the hole and inserted into the second connecting hole. Then, tightening the first nut locks the tie rod, thereby fixing the angle steel at the beam-column connection. This solves the problem mentioned in the background art where drilling holes in the beam and column is required when installing angle steel, which can easily cause secondary structural damage to the already fragile old beams and columns.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a beam and column reinforcement structure for the renovation of old houses, comprising angle steel, wherein the angle steel includes a horizontal plate and a vertical plate, and a diagonal brace is fixed between the horizontal plate and the vertical plate. Two threaded holes are provided near both ends of the horizontal plate and the vertical plate, and bolts are threaded into the inner sides of the two threaded holes. A first connecting rod and a second connecting rod are also provided near both ends of the horizontal plate and the vertical plate, with the second connecting rod located inside the two first connecting rods. Multiple first connecting holes are provided on the inner sides of both the first and second connecting rods. A second connecting hole is provided at one end of each of the first and second connecting rods, and a pull rod is provided inside the second connecting hole. One end of the pull rod is threaded, and a first nut is threaded onto the outer side of the thread. A threaded cylinder is fixed to the other end of the pull rod, and threaded rods are threaded into the inner sides of both threaded cylinders. A second nut is fixed between the two threaded rods.

[0005] As a preferred embodiment of this utility model, the horizontal plate and the vertical plate are arranged at a 90-degree angle.

[0006] As a preferred embodiment of this utility model, the inclined bracing plate is arranged at a 45-degree angle to both the horizontal and vertical plates.

[0007] As a preferred embodiment of this utility model, a plurality of the first connecting holes are arranged at equal intervals.

[0008] As a preferred embodiment of this utility model, the two threaded holes correspond to the positions of the two first connecting holes.

[0009] As a preferred embodiment of this utility model, the pull rod has an L-shaped structure.

[0010] As a preferred embodiment of this invention, the threads of the two threaded cylinders are in opposite directions.

[0011] This utility model provides a beam and column reinforcement structure for the renovation of old houses, which has the following beneficial effects: This beam and column reinforcement structure for the renovation of old houses involves drilling holes in the floor slab and wall where the beams and columns are located. After drilling, the threaded end of the tie rod is passed through the hole and inserted into the second connecting hole. Then, tightening the first nut locks the tie rod, thus fixing the angle steel to the beam-column connection. This solves the problem of drilling holes in the beams and columns when installing angle steel, which can easily cause secondary structural damage to the already fragile old beams and columns.

[0012] 2. This beam and column reinforcement structure for the renovation of old houses solves the problem that thicker beams and columns can block the position of the second connecting hole, requiring the replacement with larger angle steel and causing inconvenience. By adjusting the positions of the first and second connecting rods, the position of the second connecting hole is moved closer to the beam and column, solving the problem that thinner beams and columns can cause the tie rod to be far from the beam and column, resulting in structural instability. This structure can be used for beams and columns of different sizes. Attached Figure Description

[0021] Please see Figures 1 to 4This utility model provides a technical solution: a beam and column reinforcement structure for the renovation of old houses, including an angle steel 1. The angle steel 1 includes a horizontal plate 101 and a vertical plate 102. A diagonal brace 2 is fixed between the horizontal plate 101 and the vertical plate 102. Two threaded holes 3 are opened near both ends of the horizontal plate 101 and the vertical plate 102. Bolts 4 are threaded into the inner side of the two threaded holes 3. A first connecting rod 5 and a second connecting rod 6 are also provided near both ends of the horizontal plate 101 and the vertical plate 102. The second connecting rod 6 is located inside the two first connecting rods 5. Multiple first connecting holes 7 are opened on the inner side of the first connecting rods 5 and the second connecting rod 6. Each end of the first connecting hole 8 is provided with a second connecting hole 8. A pull rod 9 is provided inside the second connecting hole 8. A thread 10 is provided at one end of the pull rod 9. A first nut 11 is threaded to the outside of the thread 10. A threaded cylinder 12 is fixed at the other end of the pull rod 9. A threaded rod 13 is threaded to the inside of each of the two threaded cylinders 12. A second nut 14 is fixed between the two threaded rods 13. The horizontal plate 101 and the vertical plate 102 are arranged at a 90-degree angle. The diagonal brace 2 is arranged at a 45-degree angle to both the horizontal plate 101 and the vertical plate 102. Multiple first connecting holes 7 are arranged at equal intervals. The positions of two threaded holes 3 and two of the first connecting holes 7 are corresponding. The pull rod 9 has an L-shaped structure. The thread directions of the two threaded cylinders 12 are opposite. In use, holes are drilled in the floor slab and wall where the beam and column are located. After drilling, the threaded end of the tie rod 9 (10) is passed through the hole and inserted into the second connecting hole 8. Then, the first nut 11 is tightened to lock the tie rod 9, thereby fixing the angle steel 1 at the beam-column connection. When dealing with thicker or thinner beams and columns, the thicker beams and columns may block the position of the second connecting hole 8, requiring the replacement with a larger angle steel 1, which is inconvenient. By adjusting the positions of the first connecting rod 5 and the second connecting rod 6, the position of the second connecting hole 8 is moved away from the beam and column position. Then, the bolt 4 is passed through the first connecting hole 7 on the first connecting rod 5 and the second connecting rod 6. The first connecting rod 5 and the second connecting rod 6 are threaded together with the threaded hole 3 to fix their positions. Thinner beams and columns are prone to causing the tie rod 9 to be far from the beam and column, resulting in a less stable structure. By adjusting the positions of the first connecting rod 5 and the second connecting rod 6, the position of the second connecting hole 8 is brought closer to the beam and column. Then, the bolt 4 is threaded through the first connecting hole 7 on the first connecting rod 5 and the second connecting rod 6 and threaded together with the threaded hole 3 to fix their positions. Through the above process, it is possible to deal with beams and columns of different sizes, and solve the problem that when installing angle steel, it is necessary to drill holes in the beams and columns, which can easily cause secondary structural damage to the already fragile old beams and columns.

[0022] The specific usage and function of this embodiment: When using this utility model, holes are drilled in the floor slab and wall where the beam and column are located. After drilling, the threaded end of the tie rod 9 is passed through the hole and inserted into the second connecting hole 8. Then, the tie rod 9 is locked by tightening the first nut 11, thereby fixing the angle steel 1 at the beam-column connection. When facing thicker or thinner beams and columns, thicker beams and columns may block the position of the second connecting hole 8, requiring the replacement with a larger angle steel 1, which is inconvenient to use. By adjusting the positions of the first connecting rod 5 and the second connecting rod 6, the position of the second connecting hole 8 is moved away from the beam and column position. Then, the bolt 4 is threaded through the first connecting hole 7 and the threaded hole 3 on the first connecting rod 5 and the second connecting rod 6 to fix the position of the first connecting rod 5 and the second connecting rod 6. Thinner beams and columns can cause the tie rod 9 to be far from the beam and column, making the structure less stable. By adjusting the positions of the first connecting rod 5 and the second connecting rod 6, the position of the second connecting hole 8 is brought closer to the beam and column. Then, the bolt 4 is threaded through the first connecting hole 7 and the threaded hole 3 on the first connecting rod 5 and the second connecting rod 6 to fix the position of the first connecting rod 5 and the second connecting rod 6. Through the above process, it is possible to deal with beams and columns of different sizes.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
