[0018] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0019] This application discloses a reinforcement structure for the renovation of old houses. (Refer to...) Figure 1 The old house renovation and reinforcement structure includes a reinforcement plate 1, which is an angle steel. The reinforcement plate 1 is fastened to the corner of the structural column 2. It also includes a stirrup 3 around the reinforcement plate 1. The stirrup 3 is slidably set on the reinforcement plate 1 and slides along the length of the reinforcement plate 1. Reference Figure 1 , Figure 2 and Figure 3 It also includes a reinforcing seat 4, which is an angle steel and fastens to the corner of the structural column 2. The reinforcing seat 4 is located at both ends of the reinforcing plate 1. The reinforcing seat 4 is used to fit between the reinforcing plate 1 and the ground and roof. A driving block 5 is provided between the reinforcing seat 4 and the reinforcing plate 1. The driving block 5 is used to drive the reinforcing seat 4 and the reinforcing plate 1 to move in opposite directions so that the reinforcing seat 4 is supported between the ground and the roof.

[0020] When reinforcing structural column 2, the reinforcing plate 1 is fastened to the corner of structural column 2, and then the reinforcing plate 1 and structural column 2 are connected by using stirrups 3. Then, the reinforcing seat 4 is placed at the end of the reinforcing plate 1, and the driving block 5 is inserted into the gap between the reinforcing seat 4 and the reinforcing plate 1. As the driving block 5 enters the gap, it drives the reinforcing seat 4 and the reinforcing plate 1 to move in opposite directions, so that the reinforcing seat 4 is pressed against the roof. This allows the reinforcing plate 1 and structural column 2 to jointly support the building, thereby improving the building's safety. At the same time, under the action of the stirrups 3 and the reinforcing plate 1, the deformation of structural column 2 is limited, improving the deformation resistance of structural column 2 and further improving the building's safety.

[0021] Reference Figure 1 In this embodiment, to facilitate the connection of the stirrup 3 to the reinforcing plate 1, the stirrup 3 includes a U-shaped rod 31 with an opening and a sleeve 32. The U-shaped rod 31 is made of bent steel bars, and the sleeve 32 is located inside the opening of the U-shaped rod 31. The U-shaped rod 31 includes multiple horizontal bars that are hinged to each other. The ends of the horizontal bars at the beginning and end are provided with threaded sections, and the threaded directions of the threaded sections on both sides are opposite. The sleeve 32 is threadedly connected to the horizontal bars. After the reinforcing plate 1 is fastened to the corner of the structural column 2, the U-shaped rod 31 is pulled outward so that the U-shaped rod 31 is connected to the reinforcing plate 1. Then, the sleeve 32 is moved into the opening of the U-shaped rod 31 and threadedly connected to the U-shaped rod 31 to complete the locking of the U-shaped rod 31.

[0022] Reference Figure 1 To reduce the possibility of the stirrup 3 slipping off accidentally, a support block 6 is fixedly installed on the reinforcing plate 1, and the stirrup 3 is supported on the support block 6; the support block 6 limits the stirrup 3, reducing the possibility of the stirrup 3 slipping off.

[0023] Reference Figure 3 and Figure 4 In this embodiment, the drive block 5 has a triangular cross-section and is made of metal. The surfaces of the reinforcing plate 1 and the reinforcing seat 4 that abut against each other are inclined and adapted to the inclined surface of the drive block 5. During the process of the drive block 5 entering the reinforcing plate 1 and the reinforcing seat 4, it drives the reinforcing plate 1 and the reinforcing seat 4 to move in opposite directions. The drive block 5 is driven between the reinforcing plate 1 and the reinforcing seat 4 to drive the reinforcing seat 4 to move and then abut against the roof and the ground. The operation is simple and convenient.

[0024] Reference Figure 3 and Figure 4 To reduce the possibility of the drive block 5 moving out under the pressure of the reinforcing seat 4 and the reinforcing rod, a limiting ring 7 is also included. The limiting ring 7 is used to sleeve the drive block 5 and apply a driving force to the drive block 5 to move in the direction of the structural column 2. The limiting ring 7 limits the drive block 5 to increase the pressure on the reinforcing plate 1 and the reinforcing seat 4, thereby reducing the possibility of the drive block 5 being accidentally moved out.

[0025] Reference Figure 3 and Figure 4 To reduce the possibility of the limiting ring 7 separating from the driving block 5, an annular groove is provided on the inner side of the limiting ring 7. The ends of the annular groove are connected in a ring shape. The tail of the driving block 5, which is away from the structural column 2, is slidably engaged in the annular groove. The end of the driving block 5 is located in the annular groove, which limits the position of the limiting ring 7, thereby reducing the possibility of the limiting ring 7 falling off.

[0026] Reference Figure 3 In this embodiment, to reduce the damage caused by the reinforcing base 4 to the building structure, a support plate 8 is fixedly installed at the end of the reinforcing base 4 away from the reinforcing plate 1. The area of ​​the support plate 8 is larger than the bottom area of ​​the reinforcing base 4. The support plate 8 is used to support the ground and roof. Multiple ribs 9 are fixedly installed between the support plate 8 and the reinforcing base 4. The ribs 9 are spaced apart and evenly distributed. Under the action of the support plate 8, the contact area between the reinforcing base 4 and the ground and roof is increased, thereby reducing the damage to the building structure. Under the action of the ribs 9, the possibility of the support plate 8 bending under load is reduced.

[0027] Reference Figure 3 and Figure 4 In this embodiment, the drive block 5 includes a triangular block 51 and a sliding plate 52. The triangular block 51 is an isosceles triangle and is a telescopic structure. The triangular block 51 extends and retracts in a direction perpendicular to the base. The sliding plate 52 is located on both sides of the triangular block 51 and is slidably disposed on the largest sleeve of the triangular block 51. The sliding plate 52 is located between the reinforcing plate 1 and the reinforcing seat 4. The drive block 5 is a telescopic structure, which makes it easy for the drive block 5 to maintain a tendency to move toward the structural column 2 after its end abuts against the structural column 2, so as to support the reinforcing seat 4 and the reinforcing plate 1, thereby ensuring the supporting force applied by the drive block 5 to the reinforcing plate 1 and the reinforcing seat 4.

[0028] Reference Figure 3 and Figure 4In this embodiment, a sliding plate 52 is slidably mounted on the surfaces of the reinforcing base 4 and the reinforcing plate 1, with a rod 10 attached thereto. The sliding direction of the rod 10 is parallel to the length direction of the reinforcing plate 1. The surfaces of the reinforcing base 4 and the reinforcing plate 1 facing the sliding plate 52 have slots 11 for the rod 10 to be inserted into. A spring is mounted on the sliding plate 52, and the rod 10 is sleeved inside the spring. One end of the spring is fixedly mounted on the sliding plate 52, and the other end is fixedly mounted in the middle of the rod 10. The sliding plate 52 is fixed to the reinforcing plate 1 and the reinforcing base 4 by the rod 10 and the slots 11, reducing the possibility of the sliding plate 52 sliding out under the action of extrusion force, thereby facilitating the driving block 5 to provide support for the reinforcing base 4 and the reinforcing plate 1 for a longer period of time.

[0029] Reference Figure 3 and Figure 4 In this embodiment, the limiting ring 7 is open, and a connecting rod 12 is provided at each opening of the limiting ring 7. The connecting rods 12 on both sides are arranged vertically in a vertical direction, and there is an adjustment space between the connecting rods 12 on both sides and the inner wall of the opening. It also includes an adjusting component for adjusting the distance between the connecting rods 12 and the inner wall of the opening to adjust the inner diameter of the limiting ring 7. The adjusting component includes a gear 13 located between the connecting rods 12 and a toothed groove 14 formed on the connecting rods 12. The gear 13 and the toothed groove 14 mesh with each other, allowing for... Firstly, a mounting shaft is coaxially mounted on gear 13, and the mounting shaft is rotatably mounted on structural column 2. When gear 13 is rotated, gear 13 drives connecting rod 12 to move closer to each other, thereby adjusting the diameter of limiting ring 7 to facilitate applying extrusion force to drive the drive block 5, thereby driving the reinforcing seat 4 and reinforcing plate 1. Furthermore, a ratchet 15 is sleeved on the mounting shaft, and a pawl 16 that meshes with the ratchet 15 is rotatably mounted on structural column 2. The pawl 16 is engaged with the ratchet 15 to prevent gear 13 from retracting.

[0030] The implementation principle of a structural reinforcement method for old building renovation in this application is as follows: When reinforcing structural column 2, the reinforcing plate 1 is fastened to the corner of structural column 2, and then the reinforcing plate 1 and structural column 2 are connected by stirrups 3. The reinforcing seat 4 is then placed at the end of the reinforcing plate 1, and the driving block 5 is inserted into the gap between the reinforcing seat 4 and the reinforcing plate 1. As the driving block 5 enters the gap, it drives the reinforcing seat 4 and the reinforcing plate 1 to move in opposite directions, causing the reinforcing seat 4 to press against the roof. This allows the reinforcing plate 1 and structural column 2 to jointly support the building, thereby improving the building's safety. Simultaneously, the stirrups 3 and the reinforcing plate 1 limit the deformation of structural column 2, improving its resistance to deformation and further enhancing the building's safety. Furthermore, when the driving block 5 enters between the reinforcing seat 4 and the reinforcing plate 1, the reinforcing plate 1 tends to bend. The stirrups 3 resist this bending tendency, facilitating the reinforcing plate 1's support of the building.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
