Description

Technical Field

[0001] This utility model relates to the field of building reinforcement technology, specifically to a seismic-resistant reinforcement structure for the renovation of old buildings. Background Technology

[0002] Existing buildings refer to buildings that have been completed and put into use, including residential buildings, public buildings, and industrial buildings. As the service life of existing buildings gradually increases, the building structure is subject to certain harmful environmental erosion or aging of materials such as concrete, which may pose certain safety hazards, thus requiring renovation. In particular, for existing old buildings, the stress-bearing capacity of the walls gradually decreases with the increase of their service life, so seismic reinforcement is required for safety.

[0003] According to Chinese Patent Publication No. CN222140802U, a prefabricated seismic reinforcement and renovation structure for existing buildings is disclosed, including a slot set on one side of the wall, a connecting steel inserted into the slot, and multiple wing plates fixedly connected to both sides of the connecting steel. Through holes are opened between the wing plates and the wall, and expansion bolts for fixing the wing plates are installed in the through holes, so that the overall structure can be integrated with the wall, increasing the seismic resistance of the structure. In contrast, most existing seismic reinforcement and renovation methods only use bolts and steel plates.

[0004] However, the above solution requires multiple expansion bolts and fixing bolts for fixation, which necessitates drilling multiple fixing holes in the wall. This reduces the strength of the wall itself and makes the wall prone to rainwater leakage during subsequent use, further increasing the difficulty of installation and fixation. In addition, the above solution requires placing the I-beam connecting steel in the triangular groove. Due to the fixed wall structure of old buildings, the I-beam connecting steel is not easy to insert into the triangular groove due to length limitations, reducing the actual installation efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a seismic-resistant and reinforced structure for the renovation of old buildings, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a seismic-resistant and reinforced old building renovation structure, comprising a wall, an installation groove on the side of the wall, an installation plate inside the installation groove, a placement cavity inside the installation plate, the inner wall of the placement cavity being rotatably fitted with one end of a threaded rod, a movable plate outside the threaded rod being movably hinged to a hinge plate, a fixing rod on the side of the installation plate, a fixing plate installed on the side of the installation plate, a slot on the side of the fixing plate, a reinforcing plate inside the slot, both ends of the reinforcing plate being fixedly connected to the slot plate, a fireproof board attached to the side of the wall, a clearance groove inside the fireproof board, and a decorative panel fixedly installed on the surface of the fireproof board.

[0007] Preferably, limiting grooves are provided on both sides of the mounting groove, the mounting groove is connected to the limiting grooves, and the limiting grooves are movably inserted into the outer side of the fixing rod.

[0008] Preferably, the placement cavity is slidably fitted with the movable plate, and the movable plate is threadedly fitted with the outer side of the threaded rod through a threaded hole.

[0009] Preferably, the mounting plate has a clearance hole on its side, and the mounting plate slides with the outer side of the fixing rod through the clearance hole. One end of the fixing rod extends into the placement cavity and is hinged to one end of the hinge plate.

[0010] Preferably, the mounting plate has threaded holes on its side, and the mounting plate is connected and fixed to the fixing plate by fastening bolts.

[0011] Preferably, the fixing plate is engaged with the reinforcing plate via a slot, and the reinforcing plate is engaged with the fireproof plate via a clip.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention involves placing an installation plate in an installation groove, rotating a threaded rod to move a movable plate, which in turn moves a fixed rod via a hinged plate until the fixed rod is inserted into the placement cavity. The fixed rod prevents the installation plate from detaching from the installation groove. The fireproof board is then attached to the wall, and a reinforcing plate is placed in a recessed groove. The retaining plates at both ends of the reinforcing plate are inserted into retaining slots. Tightening bolts connects and secures the fixed plate to the installation plate, thus connecting and fixing the reinforcing plate and fireproof board to the wall. The installation plate and reinforcing plate effectively enhance the earthquake resistance of old building walls, while avoiding the need to drill holes in the wall surface to fix the reinforcing plate. This increases installation efficiency and reduces damage to old building walls. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 This utility model provides a technical solution: a seismic-resistant and reinforced renovation structure for old buildings, including a wall 1. An installation groove 2 is formed on the side of the wall 1. The installation groove 2 is a rectangular groove. Limiting grooves 3 are formed on both sides of the installation groove 2. The installation groove 2 communicates with the limiting grooves 3. The limiting grooves 3 are movably inserted into the outer side of a fixing rod 9. By inserting the fixing rod 9 into the limiting groove 3, the mounting plate 4 can be fixed inside the installation groove 2, preventing the mounting plate 4 from detaching or loosening from the installation groove 2. Simultaneously, the fixing rods 9 on both sides provide support to the inner wall of the limiting groove 3, thus supporting the wall 1. The mounting slot 2 is movably engaged with the mounting plate 4. The mounting plate 4 has a rectangular cavity 5 inside, which slides within a movable plate 7. The movable plate 7 is threadedly engaged with the outer side of a threaded rod 6 via a threaded hole. The inner wall of the cavity 5 is rotatably engaged with one end of the threaded rod 6. Rotating the threaded rod 6 allows the movable plate 7 to move within the cavity 5. The movable plate 7 is hinged to one end of the hinge plate 8 via a hinge slot. A clearance hole is provided on the side of the mounting plate 4, through which the mounting plate 4 slides with the outer side of the fixing rod 9. The fixing rods 9 are evenly distributed in a linear array on both sides of the mounting plate 4. One end of each fixing rod extends into the placement cavity 5 and is hinged to the other end of the hinge plate 8. The movement of the movable plate 7 within the placement cavity 5 drives the hinge plate 8, causing the fixing rods 9 to move outwards until they reach the limiting groove 3. This fixes the mounting plate 4 within the mounting groove 2, preventing it from detaching or becoming loose. Threaded holes are provided on the side of the mounting plate 4. The mounting plate 4 is connected and fixed to the fixing plate 10 by fastening bolts 11. This effectively avoids drilling holes in the wall 1, ensuring the integrity of the wall 1 in old buildings and preventing leakage. Meanwhile, the side of the fixing plate 10 has a slot 12, and the two ends of the reinforcing plate 13 are fixedly connected to the slot 14. The side of the wall 1 is attached to the fireproof board 16, and one side of the fireproof board 16 is bonded and fixed to the insulation board to enhance the insulation effect of the old building. The fireproof board 16 has a clearance groove 15 inside, and a decorative plate 17 is fixedly installed on the surface of the fireproof board 16. The fixing plate 10 is engaged with the reinforcing plate 13 through the slot 12, and the reinforcing plate 13 is engaged with the fireproof board 16 through the slot 14. By placing the slots 14 on both sides of the reinforcing plate 13 inside the slot 12, the mounting plate 4 can be connected and fixed to the fixing plate 10 through the reinforcing plate 13. At the same time, under the limiting action of the slot 12, the reinforcing plate 13 is fixed inside the clearance groove 15. The fireproof board 16 is further fixed by the reinforcing plate 13. That is, seismic reinforcement can be carried out without drilling holes in the surface, and the efficiency of the workers can be effectively improved. Working principle: In use, the mounting plate 4 is attached to the inner wall of the mounting groove 2. Then, the threaded rod 6 is rotated to move the movable plate 7 inside the placement cavity 5. The fixing rod 9 is moved outward through the hinge plate 8 until it moves into the limiting groove 3, thus fixing the mounting plate 4 inside the mounting groove 2 to prevent it from loosening. Then, the fireproof board 16 is attached to the wall 1, and the reinforcing plate 13 is placed inside the relief groove 15. The fireproof board 16 is fixed to the surface of the wall 1 through the relief groove 15. At the same time, the fixing plate 10 is attached to the mounting plate 16. The side of the plate 4 is fitted together, and the clamping plates 14 on both sides of the reinforcing plate 13 are placed inside the clamping groove 12. The mounting plate 4 and the fixing plate 10 can be connected and fixed by the reinforcing plate 13. At the same time, the reinforcing plate 13 is fixed inside the relief groove 15 under the limiting effect of the clamping groove 12. The fireproof plate 16 is further fixed by the reinforcing plate 13. That is, seismic reinforcement can be carried out without drilling holes on the surface. At the same time, through the cooperation of the mounting plate 4 and the reinforcing plate 13, the stress is effectively evenly distributed while enhancing the support strength and improving the seismic performance of old buildings.
