Description

An external wall scaffolding connection structure for the renovation of existing buildings Technical Field

[0001] This utility model relates to the field of scaffolding technology, specifically to a connection structure for exterior wall scaffolding used in the renovation of existing buildings. Background Technology

[0002] The core function of the external wall scaffolding connection structure is to reliably connect the scaffolding to the main building structure, thereby enhancing the overall stability of the scaffolding. Rigid components such as steel pipes, fasteners, and embedded parts can be used to firmly connect the scaffolding to the main building structure through welding, bolt fixing, and other methods. This can effectively resist external forces such as wind loads and construction loads, and prevent overturning or collapse.

[0003] Chinese Patent Publication No. CN216142383U discloses a wall scaffolding connection mechanism for construction engineering, including scaffolding, wall connection components fixedly connected to the outer circle of the scaffolding, and connection components evenly distributed on the scaffolding. This wall scaffolding connection mechanism for construction engineering involves screwing one end of a screw rod into a pre-embedded expansion member, fixing the scaffolding in the first and second clamps with bolts, adjusting the distance between the scaffolding and the wall by rotating the adjusting sleeve, and unscrewing one end of the screw rod from the pre-embedded expansion member for easy reuse of the reusable parts. One end of the horizontal connecting rod and one end of the vertical connecting rod are fixedly connected to the plate plate through the cooperation between the connector and the clamp. This connection method can withstand vertical upward or downward loads and can withstand certain bending moments, punching shears, and torques, enabling the scaffolding to form a spatial structure support with good stability.

[0004] In the aforementioned prior art, fixed sleeves and adjusting sleeves can be set on the scaffolding and connected to the wall to achieve the connection and support of the scaffolding. However, the vertical angle of the support component is fixed and not easy to adjust. Furthermore, some walls have a certain degree of inclination, which makes it impossible to keep the support component perpendicular to the wall during installation, affecting the stability of the scaffolding. Therefore, an external wall scaffolding connection structure for existing building renovation is needed to meet people's needs. Summary of the Invention

[0005] The purpose of this utility model is to provide a connection structure for external wall scaffolding for the renovation of existing buildings, so as to solve the problems mentioned in the background art, where the vertical angle of the support components of the scaffolding connection mechanism is fixed and not easy to adjust, and some wall surfaces have a certain degree of inclination, which makes it impossible to keep the support components perpendicular to the wall surface during installation, thus affecting the stability of the scaffolding support.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a connecting structure for exterior wall scaffolding used in the renovation of existing buildings, comprising scaffolding; two arc-shaped fasteners one and two arc-shaped fasteners two are movably installed on the scaffolding, connecting screws one are threaded onto the two arc-shaped fasteners one, connecting screws two are threaded onto the two arc-shaped fasteners two, a supporting structure is connected to the corresponding arc-shaped fasteners one, an adjusting structure is connected to the supporting structure, and a reinforcing structure is connected to the two arc-shaped fasteners two.

[0007] Preferably, the support structure includes a movable seat, which is rotatably mounted on a corresponding arc-shaped fastener. A support sleeve is installed on one side of the movable seat, and a threaded support rod is slidably installed inside the support sleeve. An angle iron is welded to one end of the threaded support rod, and an expansion bolt is detachably installed inside the angle iron.

[0008] Preferably, the angle iron has a slotted hole inside, and the expansion bolt is movably installed in the slotted hole.

[0009] Preferably, the adjustment structure includes an adjustment sleeve, which is rotatably fitted onto the support sleeve rod. The adjustment sleeve has a threaded hole inside, and the threaded support rod is threadedly installed inside the threaded hole.

[0010] Preferably, a limiting ring is rotatably installed inside the adjusting sleeve, and the limiting ring is fixedly sleeved on the support sleeve rod.

[0011] Preferably, the reinforcement structure includes two diagonal braces, which are rotatably mounted on two arc-shaped fasteners. One end of each diagonal brace is equipped with a fixing screw, and the same U-shaped support rod is slidably sleeved on the two fixing screws. A fixing seat is installed below the angle iron, and two mounting screw holes are opened inside the fixing seat. Two mounting screws are movably installed inside the U-shaped support rod, and the two mounting screws are threaded into the two mounting screw holes respectively.

[0012] Preferably, the fixing screw is threaded with two limiting nuts, which are in contact with both sides of the U-shaped support rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) In this utility model, holes can be made at corresponding positions on the wall during installation. The arc-shaped fastener is then placed on the scaffold and locked with a connecting screw. The position of the angle iron can be adjusted by rotating the adjusting sleeve so that the angle iron can be adjusted according to the position of the wall and the scaffold. The angle iron is made to contact the wall and the strip hole is aligned with the hole. At this time, the expansion bolt is passed through the strip hole and fixed in the hole to fix the position of the angle iron. The support sleeve, threaded support rod and angle iron can achieve the support effect of the scaffold. The angle iron can be adjusted by flipping it so that the angle iron can be installed and used on walls with different inclinations.

[0015] (2) After the angle iron is installed, the two arc-shaped fasteners can be set on the scaffold and locked with the connecting screw. Then, the position of the U-shaped support rod is adjusted by rotating the limit nut. The U-shaped support rod is then fixed to the fixed seat with the installation screw. At this time, the diagonal support rod, the fixing screw and the U-shaped support rod can provide diagonal support for the angle iron, forming a triangular structure, which further improves the support effect on the scaffold.

Detailed Implementation

[0022] 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.

[0023] Example 1: Please refer to Figures 1-5. This utility model provides a technical solution: a connecting structure for exterior wall scaffolding used in the renovation of existing buildings, including scaffolding 100; two arc-shaped fasteners 1 200 and two arc-shaped fasteners 2 400 are movably installed on scaffolding 100. Connecting screws 1 201 are threaded onto the two arc-shaped fasteners 1 200, and connecting screws 2 401 are threaded onto the two arc-shaped fasteners 2 400. A support structure is connected to the corresponding arc-shaped fasteners 1 200, and an adjustment structure is connected to the support structure. A reinforcement structure is connected to the two arc-shaped fasteners 2 400. During installation, the two arc-shaped fasteners 1 200 and the two arc-shaped fasteners 2 400 are fixed to scaffolding 100 using connecting screws 1 201 and connecting screws 2 401, respectively. The length of the support structure is adjusted using the adjustment structure, and the support structure is connected to the wall. The support structure can support scaffolding 100, and the reinforcement structure can improve the stability of the support structure.

[0024] Furthermore, the support structure includes a movable seat 202, which is rotatably mounted on a corresponding arc-shaped fastener 200. A support sleeve 203 is installed on one side of the movable seat 202. A threaded support rod 204 is slidably installed inside the support sleeve 203. An angle iron 205 is welded to one end of the threaded support rod 204. An expansion bolt 206 is detachably installed inside the angle iron 205. First, corresponding holes are made in the building wall. The two arc-shaped fasteners 200 are fitted onto the scaffolding 100 and locked using connecting screws 201. By flipping the support sleeve 203, the movable seat 202 can be rotated on the side of the corresponding arc-shaped fastener 200, which can change the angle of the angle iron 205 to adapt to the inclined wall. Then, the expansion bolt 206 is passed through the strip hole 207 and fixed in the hole, thus fixing the angle iron 205 to the side of the wall and reinforcing the scaffolding 100.

[0025] Furthermore, the angle iron 205 has a strip-shaped hole 207 inside, and the expansion bolt 206 is movably installed in the strip-shaped hole 207. The strip-shaped hole 207 is designed to be elongated, so that the expansion bolt 206 can be adjusted in position within the strip-shaped hole 207 according to the opening position of the hole.

[0026] Furthermore, the adjustment structure includes an adjustment sleeve 300, which is rotatably fitted onto the support sleeve rod 203. The adjustment sleeve 300 has a threaded hole 301 inside, and the threaded support rod 204 is threadedly installed inside the threaded hole 301. Rotating the adjustment sleeve 300 allows it to move through the threaded engagement between the threaded hole 301 and the threaded support rod 204, thereby causing the threaded support rod 204 to move the angle iron 205 and make it contact the wall, so as to adjust the position of the angle iron 205 according to the wall and the erection position of the scaffolding 100.

[0027] Furthermore, a limiting ring 302 is rotatably installed inside the adjusting sleeve 300. The limiting ring 302 is fixedly sleeved on the support sleeve rod 203. When the adjusting sleeve 300 rotates, it will rotate on the limiting ring 302. By setting the limiting ring 302, the rotation position of the adjusting sleeve 300 can be restricted, preventing the adjusting sleeve 300 from coming loose from the support sleeve rod 203.

[0028] Example 2: As shown in Figures 1-4, the reinforcement structure includes two diagonal braces 402, which are rotatably mounted on two arc-shaped fasteners 400. One end of each diagonal brace 402 is fitted with a fixing screw 403. A U-shaped support 404 is slidably fitted onto the two fixing screws 403. A fixing seat 405 is installed below the angle iron 205. Two mounting screw holes 406 are opened inside the fixing seat 405. Two mounting screws 407 are movably installed inside the U-shaped support 404. The two mounting screws 407 are threaded into the two mounting screw holes 406. Two limiting nuts 408 are threaded onto the fixing screws 403. The limiting nuts 408 contact both sides of the U-shaped support rod 404. The two arc-shaped fasteners 400 are fitted onto the scaffold 100 and locked using the connecting screws 401. The position of the U-shaped support rod 404 can be adjusted by rotating the corresponding limiting nuts 408. Then, the diagonal support rod 402 is flipped so that the pre-set hole on the U-shaped support rod 404 is aligned with the mounting screw hole 406. Subsequently, the mounting screw 407 is passed through the U-shaped support rod 404 and screwed into the mounting screw hole 406 to fix one end of the U-shaped support rod 404. With the cooperation of the diagonal support rod 402, the fixing screw 403 and the U-shaped support rod 404, the angle iron 205 can be provided with diagonal support. The remaining features are the same as in Embodiment 1.

[0029] The working principle is as follows: During installation, corresponding holes are first drilled in the building wall. Two arc-shaped fasteners 200 are then fitted onto the scaffolding 100. The two arc-shaped fasteners 200 are locked in place using connecting screws 201. Then, the threaded support rod 204 is adjusted according to the distance between the scaffolding 100 and the wall. The angle iron 205 can be held and the adjusting sleeve 300 rotated. The continuously rotating adjusting sleeve 300, through the threaded engagement between the threaded hole 301 and the threaded support rod 204, drives the threaded support rod 204 to move, thus causing the threaded support rod 204 to move the angle iron. 205 moves and comes into contact with the wall. During this process, the support sleeve 203 can drive the movable seat 202 to rotate on the side of the corresponding arc-shaped fastener 200, which can change the angle of the angle iron 205 to adapt to the inclined wall. Then, the expansion bolt 206 is passed through the strip hole 207 and fixed in the hole, thus fixing the angle iron 205 to the side of the wall to reinforce the scaffolding 100. After fixing, the two arc-shaped fasteners 400 are put on the scaffolding 100 and locked with the connecting screw 401. By rotating the corresponding limit... The limiting nut 408 can be moved through its threaded engagement with the fixing screw 403, allowing it to move on the fixing screw 403 and disengage from the U-shaped support rod 404. At this point, the position of the U-shaped support rod 404 can be adjusted, allowing it to slide on the fixing screw 403. The movement distance of the U-shaped support rod 404 can be adjusted according to the movement distance of the angle iron 205. After adjustment, the limiting nut 408 is rotated in the opposite direction to make it adhere tightly to the surface of the U-shaped support rod 404, thus re-limiting the position of the U-shaped support rod 404. Then, the inclined plane is flipped... The strut 402 causes the U-shaped strut 404 to rotate via the fixing screw 403, aligning the pre-set hole on the U-shaped strut 404 with the mounting screw hole 406. Then, the mounting screw 407 is passed through the U-shaped strut 404 and screwed into the mounting screw hole 406 to fix one end of the U-shaped strut 404. With the cooperation of the diagonal strut 402, the fixing screw 403 and the U-shaped strut 404, the angle iron 205 can be provided with diagonal support, while further improving the support stability of the support sleeve 203, the threaded strut 204 and the angle iron 205.
