Description

Technical Field

[0001] This utility model relates to the field of cantilever frame technology, specifically an assembly and fixing device for cantilever frames. Background Technology

[0002] A cantilever scaffold is a type of external scaffolding used in construction, where the vertical load is transferred to the main structure through a bottom steel support frame. It consists of a steel support frame, a coupler-type steel pipe scaffold, and wall ties. The main functions of a cantilever scaffold include supporting the building structure and providing safety protection for workers.

[0003] The existing utility model with authorization announcement number CN218758665U discloses a fixing device for cantilevered external scaffolding, including a movable sleeve. A column and a retaining ring are fixedly connected to the upper surface of the movable sleeve. A fixing screw is fixedly connected to the movable sleeve. A fixing hole is opened on the upper surface of the movable sleeve. The fixing screw is inserted into the fixing hole. A fixing nut is threaded on the fixing screw. A protective frame is provided above the movable sleeve.

[0004] The above technical solution, by setting a fixing screw and a fixing nut, enables the connection and disassembly of the movable sleeve to the I-beam, thereby facilitating the change of the installation position of the movable sleeve on the I-beam without damaging the I-beam. It provides good protection for the finished product and allows for reuse while reducing material waste. However, the above technical solution, by using the fixing screw and fixing nut, can only change the installation position of the movable sleeve on the I-beam, but cannot reinforce the cantilever frame. During use, it is easily affected by vibration and shaking, causing the cantilever frame to tilt and easily leading to instability and displacement of the cantilever frame position.

[0005] Therefore, those skilled in the art have provided an assembly and fixing device for cantilever frames to solve the problems mentioned in the background art. Utility Model Content

The inner wall of each first fixing frame 202 is threaded with four fixing bolts 208. A reinforcing plate 3 is fixedly connected to the outer surface of each steel frame 201. The back of each reinforcing plate 3 is fixedly connected to the front of the wall 1. The reinforcing plates 3 can reinforce the steel frame 201 and the wall 1, thereby enhancing the stability of the device.

[0024] The outer surface of each set of fixing bolts 208 is threaded to the inner wall of the second fixing frame 203. Two fixing plates 206 are fixedly connected to the outer surface of each first fixing frame 202. Two rotating shafts 217 are slidably connected inside each first fixing frame 202. Four reinforcing bolts 4 are threaded to the inner wall of each reinforcing plate 3. The outer surface of each set of reinforcing bolts 4 is threaded to the inner wall of the wall 1. The position of the reinforcing plate 3 can be reinforced by the reinforcing bolts 4 to prevent it from shaking or shifting during use.

[0025] Two support limiting plates 214 are fixedly connected to the outer surface of each set of rotating shafts 217. Four fixing blocks 216 are fixedly connected to the side of each set of support limiting plates 214 that are far apart from each other. A fixing rod 215 is fixedly connected to the side of each set of fixing blocks 216 that are close to each other. Two sliding grooves 207 are opened on the upper surface of each set of fixing plates 206. Four support frames 5 are fixedly connected to the outer surface of each set of support frames 5 that are close to each other. The side of each set of support frames 5 is fixedly connected to the outer surface of the first fixing frame 202. The fixing plates 206 can be fixed through the support frames 5, which has a strong fixing and support effect.

[0026] Each set of slide grooves 207 has two sliding blocks 211 slidably connected inside, and each set of sliding blocks 211 has two rotating rods 212 slidably connected inside. The outer surface of each set of rotating rods 212 is fixedly connected to two connecting plates 213. The inner wall of each set of connecting plates 213 is in contact with the outer surface of the fixing rods 215. The inner wall of each set of fixing plates 206 is threadedly connected to two threaded rods 209. The outer surface of each set of fixing blocks 216 is fixedly connected to a reinforcing frame 6. The side of each set of reinforcing frames 6 that is close to each other is fixedly connected to the side of each set of supporting limiting plates 214 that is far away from each other. Through the reinforcing frame 6, the fixing blocks 216 and supporting limiting plates 214 can be fixed to prevent their position from shifting during operation.

[0027] Two bearings 210 are fixedly connected to the outer surface of each set of threaded rods 209. The ends of each set of bearings 210 that are close to each other are fixedly connected to the sides of two sliding blocks 211 that are far from each other.

Several identical limit bolts 7 are threadedly connected to the inner wall of each set of reinforcing frames 6. The outer surface of each set of limit bolts 7 is threadedly connected to the inner wall of the supporting limit plate 214. The position of the reinforcing frame 6 can be restricted by the limit bolts 7 to prevent the position from shaking or shifting.

[0028] The working principle of this utility model is as follows: In use, firstly, the first fixing frame 202 is installed on the steel frame 201, then the first fixing frame 202 is moved to an appropriate position, and then the second fixing frame 203 is installed on the steel frame 201. By rotating the fixing bolt 208, the first fixing frame 202 and the second fixing frame 203 are fixed on the steel frame 201, thereby enabling the cantilever support rod 204 to be installed on the first fixing frame 202. Furthermore, the position of the cantilever support rod 204 can be restricted by the limiting bolt 205, achieving the purpose of fixing and limiting, and enhancing the stability of the device. Then, the shaft is driven by twisting the threaded rod 209. The support 210 moves in the slide groove 207, thereby driving the sliding block 211 to slide in the slide groove 207. This pushes the support limiting plate 214, which can further fix the position of the cantilever support rod 204. Thus, the upper and lower ends of the cantilever support rod 204 can be fixed simultaneously by two fixing mechanisms 2, which has a strong fixing effect and enhances the use effect of the device. It can effectively avoid the problem that the cantilever support rod 204 cannot be reinforced and is easily affected by vibration and shaking during use, causing the cantilever frame to tilt and the position of the cantilever support rod 204 to become unstable.
