[0002] A cantilevered scaffolding refers to a scaffolding whose frame structure is unloaded on a rigid cantilever beam attached to a building structure, and is used for the operation and safety protection requirements of the main body or decoration project in building construction.

[0003] Currently, in order to improve the bearing capacity of the cantilevered scaffolding, the current existing technology will use diagonal braces or steel cables, and add another set of fixed points on the building wall, and carry out diagonal tension reinforcement protection through the diagonal braces or steel cables.

[0050] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be described clearly and completely. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0051] By providing a special construction protection device and method for a cantilever scaffold in the embodiments of the present application, the problems in the prior art are solved. When installing the diagonal brace or steel cable, there are inconveniences. Since the length of the diagonal brace or steel cable cannot perfectly match the reinforcement distance of the fixed points on the wall, a corresponding locking device needs to be used for limiting. The traditional locking device is inconvenient to operate, time-consuming and laborious. At the same time, if the locking device fails, the protection is lost, and no warning can be issued either. As a result, the cantilever scaffold is used in an un-reinforced state, which poses risks.

[0052] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the specification drawings and specific embodiments.

[0053] Embodiment 1:

[0054] An embodiment of the present invention discloses a special construction protection device for a cantilever scaffold. As shown in the attached Figure 1 to Figure 8 figures, it includes a protection frame 1, a wall fixing unit 3, a protection steel cable 2, a locking mechanism 4 and a detection component 5;

[0055] The protection frame 1 is sleeved on the cantilever steel structure frame 6;

[0056] The wall fixing unit 3 is arranged on the wall body 7. The wall fixing unit 3 includes a wall fixing plate 31 arranged on the wall body 7 and a rail 32 arranged on the wall fixing plate 31. An embedded seat 33 is movably clamped on the rail 32, and a hook 34 is arranged on the embedded seat 33;

[0057] The protective steel cable 2 is arranged between the protective frame 1 and the hook 34, and the protective steel cable 2 provides reinforcement protection for the protective frame 1 and the cantilever steel structure frame 6;

[0058] The locking mechanism 4 is arranged on the embedding seat 33 and is used for locking and positioning the embedding seat 33 on the card rail 32;

[0059] The detection component 5 is arranged on the card rail 32 and is used for warning the movement of the position of the embedding seat 33.

[0060] The locking mechanism 4 includes:

[0061] The locking seat 41 is arranged on the embedding seat 33;

[0062] The first lead screw 42 is threadedly connected to the locking seat 41;

[0063] The locking block 43 is arranged inside the locking seat 41. The locking block 43 is rotatably connected to the first lead screw 42, and the locking block 43 is used for clamping and locking the surface of the card rail 32.

[0064] The locking mechanism 4 has a compact structure, is convenient to operate, and is easy to realize the locking and limiting of the position between the embedding seat 33 and the card rail 32. When adjusting the position of the embedding seat 33 on the card rail 32 and locking is required, directly rotate the first lead screw 42;

[0065] When the first lead screw 42 rotates, the first lead screw 42 pushes the locking block 43 to move. The locking block 43 slides along the inside of the locking seat 41 and finally clamps with the card rail 32 to form a clamping limit, thereby locking the position between the card rail 32 and the embedding seat 33.

[0066] The locking block 43 is provided with a rack 44, and the card rail 32 is provided with a tooth groove 322 meshing with the rack 44.

[0067] A reinforcing sleeve 45 is fixedly connected to the locking seat 41, and a reinforcing rod 46 is fixedly connected to the locking block 43. The reinforcing rod 46 is slidably connected inside the reinforcing sleeve 45. Through the design of the reinforcing sleeve 45 and the reinforcing rod 46, when adjusting the position of the locking block 43, the locking block 43 drives the reinforcing rod 46 to move along the reinforcing sleeve 45. The cooperation between the reinforcing rod 46 and the reinforcing sleeve 45 provides lateral support for the locking block 43 to ensure the stable force of the locking block 43.

The detection assembly 5 is used to detect whether slippage occurs between the clamping rail 32 and the embedding base 33. If slippage occurs, an alarm will be given immediately. If no slippage occurs, it means that the force on the cantilever steel structure frame 6 is normal and there is no overload.

[0074] The protective frame 1 is provided with a locking bolt 11, and the locking bolt 11 is connected to the cantilever steel structure frame 6. Through the design of the locking bolt 11, the connection between the protective frame 1 and the cantilever steel structure frame 6 is convenient.

The first hanging bracket 21 is connected to the protective frame 1, and the second hanging bracket 22 is connected to the hook 34. Through the design of the first hanging bracket 21 and the second hanging bracket 22, the protective steel cable 2 is convenient to be quickly connected between the protective frame 1 and the wall fixing unit 3.

[0076] The second aspect of the present invention provides a method for a special construction protection device of a cantilever scaffold. The method includes the following steps. Step S1, fix the protective frame 1 on the cantilever steel structure frame 6 through the locking bolt 11;

[0077] Step S2, use expansion bolts to fix the wall fixing unit 3 on the wall body main body 7;

[0078] Step S3, hang the protective steel cable 2 on the protective frame 1 in the hook 34 on the wall fixing unit 3;

[0079] Step S4, adjust the position of the embedding base 33 on the clamping rail 32 so that the protective steel cable 2 is tightened;

[0080] Step S5, lock the position of the embedding base 33 on the clamping rail 32 through the locking mechanism 4;

[0081] Step S6: Adjust the position of the bearing platform 51 by rotating the second lead screw 54 so that the alarm button 52 is at the target detection distance below the embedding seat 33;

[0082] Step S7: Provide reinforcement and protection for the cantilever steel structure frame 6 by using the protective steel cable 2, the wall fixing unit 3 and the protective frame 1;

[0083] Step S8: When the cantilever steel structure frame 6 fails and is unstable under stress, support is provided by the protective steel cable 2, the wall fixing unit 3 and the protective frame 1. If the stress exceeds the limit, the locking mechanism 4 is damaged, and the embedding seat 33 slides between the rail 32 and presses the alarm structure 53, and an alarm is issued in time through the alarm button 52 to remind that the position of the cantilever steel structure frame 6 is abnormal.
