Description
Technical Field
[0001] This utility model relates to the field of building construction technology, and in particular to a device for repairing and reinforcing the facade of old buildings. Background Technology
[0002] In the construction industry, old buildings often suffer from cracking, peeling, hollowing, and decreased structural performance on their facades due to long-term exposure to natural environmental erosion (such as wind, sun, rain, freeze-thaw cycles, etc.), human factors (such as changes in usage function, external impacts, etc.), and the aging of their own materials. This can pose some safety hazards, such as wall cracks threatening the safety of residents and reducing the structural stability of the building, thus affecting the overall safety of the building. Therefore, it is necessary to use reinforcement devices to strengthen and repair the walls.
[0003] Traditional reinforcement and repair devices use a single panel directly fixed to the crack in the wall. This lacks a flexible connection and adjustment structure, making it difficult to adapt to the size of cracks on different facades. As a result, it is difficult to fix the reinforcement panel to both sides of the crack, affecting the reinforcement effect. Its support structure is mostly a fixed design, which cannot be dynamically adjusted according to the height or tilt angle of the wall. It has poor versatility and requires multiple on-site cutting or welding during construction, increasing construction costs and difficulty.
[0004] Therefore, developing a reinforcement device that can adjust the spacing between reinforcement plates and adjust the height of the supporting structure is of great practical value and technical significance in solving the technical bottlenecks faced by the industry. Summary of the Invention
[0005] The purpose of this utility model is to provide a device for repairing and reinforcing the exterior facade of old buildings, which can adjust the spacing between the reinforcing plates and eliminates the need for multiple on-site cutting or welding of the reinforcing plates during construction.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: It includes a first reinforcing plate, a second reinforcing plate, and a connecting assembly. The first and second reinforcing plates are used for installation on the exterior wall of a building. The second reinforcing plate is located on one side of the first reinforcing plate. The connecting assembly is installed between the first and second reinforcing plates. The connecting assembly includes two connecting sleeves, with pull rods sleeved at both ends of the connecting sleeves. A limiting mechanism for locking the positions of the connecting sleeves and the pull rods is provided between them. Two mounting seats are respectively installed on one side of the first and second reinforcing plates. A sleeve is fixed on each mounting seat. One end of the pull rod is installed inside the sleeve. A support mechanism for tilting and supporting the first and second reinforcing plates is provided on the first and second reinforcing plates.
[0007] Preferably, the support mechanism includes two support sleeves and two adjusting rods. The adjusting rods slide inside the corresponding support sleeves. The support sleeves are provided with bolt holes. The upper end of the adjusting rods is provided with a plurality of equally spaced first mounting holes. When the bolt holes of the support sleeves are aligned with any of the first mounting holes of the adjusting rods, they can be fixedly connected by bolts. The front ends of the first reinforcing plate and the second reinforcing plate are both fixed with connecting seats. The two connecting seats are rotatably installed with the two adjusting rods respectively.
[0008] Preferably, the inner wall of the support sleeve is provided with a plurality of axially distributed guide grooves evenly distributed around its circumference, and the outer wall of the adjusting rod is provided with a plurality of guide blocks evenly fixed around its circumference, the guide blocks sliding within the corresponding guide grooves.
[0009] Preferably, the limiting mechanism includes bolt holes on the connecting sleeve, and the upper end of the pull rod has multiple equally spaced second mounting holes. When the threaded hole of the connecting sleeve is aligned with any of the second mounting holes of the pull rod, they can be fixedly connected by bolts.
[0010] Preferably, the sleeve is fitted onto the pull rod, the outer wall of the pull rod is threaded, the sleeve is fixed to the pull rod by a nut, a limit block is fixed to the end of the pull rod, and the end face of the sleeve is in contact with the limit block.
[0011] Preferably, the first reinforcing plate and the second reinforcing plate are respectively provided with holes for installing expansion bolts.
[0012] Preferably, C-shaped handles are fixed to both sides of the front end of the first reinforcing plate and the second reinforcing plate.
[0013] Preferably, the lower ends of both support sleeves are rotatably mounted with support seats, which are then fixed to the ground by expansion bolts.
[0014] Compared with the prior art, the advantages of this utility model are as follows: the sliding cooperation between the tie rod and the connecting sleeve rod in the connecting component can quickly adjust the distance between the two reinforcing plates to adapt to cracks of different widths. During construction, there is no need to cut or weld the reinforcing plates on site multiple times, which improves its practicality. Through the set support mechanism, it can be adapted to cracks of different heights on the facade of old buildings. At the same time, the reinforcing plate is fixed to the wall with expansion bolts, and the support mechanism is rigidly connected to the ground to form a stable triangular structure, which improves the stability of the wall.

[0020] The present invention will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0021] like Figure 1-4 As shown, a device for repairing and reinforcing the exterior facade of an old building includes a first reinforcing plate 1, a second reinforcing plate 2, connecting components, and a support mechanism. Both the first reinforcing plate 1 and the second reinforcing plate 2 are rectangular metal plates, installed parallel to each other on both sides of the cracked area of the building's exterior wall, respectively covering the two edges of the cracks. Connecting seats 7 are bolted to the front ends of both the first and second reinforcing plates 1 and 2 for connection to the support mechanism. C-shaped handles 13 are fixed to both sides of the front ends of the first and second reinforcing plates 1 and 2 for easy handling and position adjustment during construction. The first and second reinforcing plates 1 and 2 are made of Q345B high-strength steel plates with a thickness of 8-12mm and galvanized to enhance corrosion resistance. They are fixed to the building facade with expansion bolts to ensure a tight fit between the reinforcing plates and the wall surface.
[0022] A connecting assembly is used to connect the first reinforcing plate 1 and the second reinforcing plate 2, and to adjust the distance between them to accommodate cracks of different widths. Two connecting sleeve rods 3 are provided. The connecting sleeve rods 3 are hollow rectangular metal rods with open ends. Each connecting sleeve rod 3 has a pull rod 4 on both sides. The pull rod 4 can slide horizontally inside the connecting sleeve rod 3 to achieve length adjustment. The pull rod 4 has a rectangular cross section. One end extends into the connecting sleeve rod 3, and the other end is connected to the first reinforcing plate 1 and the second reinforcing plate 2 respectively through a sleeve 6. The pull rod 4 has multiple second mounting holes 12 equidistantly opened along its length direction. It is fixed to the connecting sleeve rod 3 by bolts to lock the adjusted length.
[0023] Meanwhile, two mounting seats 5 are fixed on the outer sides of the first reinforcing plate 1 and the second reinforcing plate 2. A sleeve 6 is welded to the upper end of the mounting seat 5, and its inner diameter matches the size of the pull rod 4. After the pull rod 4 is inserted into the sleeve 6, it is fixed by the nut thread. One side of the sleeve 6 is in contact with the fixed limiting block 15 at the end of the pull rod 4 to fix the pull rod 4.
[0024] According to the crack width, the sliding tie rod 4 adjusts the relative position of the connecting sleeve rod 3 and the tie rod 4, and fixes them by passing bolts through the second mounting hole 12, so that the first reinforcing plate 1 and the second reinforcing plate 2 tighten the wall surfaces on both sides of the crack.
[0025] The support mechanism is designed to provide inclined support for the reinforcement plate, adjusting its height to accommodate different wall heights or inclination angles, thus enhancing overall stability. It comprises two support sleeves 8, which are hollow cylindrical metal rods with open bottoms, placed at an angle to the ground. A support base 14 is rotatably mounted at their lower ends. Two adjusting rods 9 are inserted into the support sleeves 8, allowing for vertical height adjustment. Guide blocks 10 are fixed to the outer walls of the adjusting rods 9, and longitudinally distributed guide grooves matching the guide blocks 10 are formed on the inner walls of the support sleeves 8, restricting the rotation of the adjusting rods 9 and ensuring vertical lifting.
[0026] The upper end of the adjusting rod 9 is rotatably connected to the connecting seat 7, so that the support mechanism can rotate around the connection point and the tilt angle can be adjusted to support the wall. The adjusting rod 9 has multiple first mounting holes 11, which correspond to the bolt holes on the side wall of the support sleeve rod 8, and the height is fixed by bolts.
[0027] The bottom of the support base 14 is provided with anti-slip texture and is fixed to the ground by expansion bolts. The lower end of the support sleeve 8 is rotatably connected to the support base 14, which facilitates the adjustment of the support angle.
[0028] When in use, first measure the width and height of the crack on the building facade to determine the installation position of the first reinforcement plate 1 and the second reinforcement plate 2. According to the crack width, adjust the length of the connecting sleeve rod 3 by sliding the tie rod 4 so that the distance between the two reinforcement plates is slightly greater than the crack width, and fix them with bolts through the second mounting hole 12.
[0029] The first reinforcing plate 1 and the second reinforcing plate 2 are fixed to the walls on both sides of the crack with expansion bolts to ensure that the plate surface is tightly attached to the wall surface. The other end of the tie rod 4 is inserted into the sleeve 6 and fixed with a nut to make the connecting component firmly connected to the reinforcing plate.
[0030] When adjusting the support mechanism, slide the adjusting rod 9 up or down according to the wall height, and fix it to the support sleeve rod 8 through the first mounting hole 11. Adjust the support height until the lower end of the reinforcing plate is at a suitable distance from the ground. Rotate the support sleeve rod 8 so that the adjusting rod 9 and the reinforcing plate connecting seat 7 form a suitable tilt angle, generally 60°-80°, to ensure that the support force is evenly distributed. Fix the support seat 14 to the ground with expansion bolts to complete the installation of the support mechanism.
[0031] The connecting assembly, through the sliding engagement of the tie rod 4 and the connecting sleeve 3, allows for quick adjustment of the distance between the two reinforcing plates to accommodate cracks of varying widths. The support mechanism, through height adjustment of the adjusting rod 9 and the support sleeve 8, can accommodate cracks of different heights on the facade of old buildings. The reinforcing plates are fixed to the wall with expansion bolts, and the support mechanism is rigidly connected to the ground, forming a stable triangular structure that enhances the stability of the wall. No on-site cutting or welding is required; assembly and adjustment can be completed simply by bolt connection, increasing construction efficiency by over 50% and reducing labor costs and construction difficulty.
