[0001] The invention relates to the technical field of building engineering, and in particular to an automatically recyclable safety flat net protection system. Background Art

[0002] Safety net protection is a common and necessary component in the construction of the main structure of a building. It can effectively prevent the accidental fall of construction waste, materials or construction workers from the upper part during the construction of the main structure. During actual construction, due to negligence in project management or poor safety awareness of operators, construction waste, materials or construction workers may accidentally fall from the external protection frame. Safety nets can effectively prevent these special situations.

[0003] At present, the traditional safety net protection is to use steel pipe fasteners to build a frame, lay a horizontal net, and leave steel bar heads on the outer wall to fix the root of the support net. It is inconvenient to operate during erection, and the fixation is not firm. When there is a lot of garbage on the net, it is not easy to clean. When cleaning, the operator needs to clean on the net, which has great safety hazards and is not conducive to the safe and civilized management and control of the construction site.

[0028] like Figure 4As shown, when the safety flat net protection system is installed on the shear wall, the fixing device includes a first fixing support 1, which is a flat plate with bolt holes. High-strength bolts 2 pass through the bolt holes on the first fixing support 1 to fix the first fixing support 1 on the shear wall.

[0029] like Figure 5 As shown, when the safety flat net protection system is installed at the window opening, the fixing device includes a second fixing support 12, and two adjustable supports 13 are arranged at the lower part of the second fixing support 12, and the two adjustable supports 13 are arranged on both sides of the window sill shear wall; specifically, the second fixing support 12 includes a horizontal fixing plate, and vertical fixing plates are vertically connected to the two sides of the horizontal fixing plate. The horizontal fixing plate and the two vertical fixing plates form an inverted U-shaped structure, and a through hole is opened at the lower part of the vertical fixing plate. The adjustable support 13 includes an adjustment seat 13-1, and the adjustment seat 13-1 is installed in the through hole of the vertical fixed plate. The adjustment seat 13-1 is internally threaded with an adjustment screw 13-2, and one end of the two adjustment screws 13-2 close to each other is connected to a support plate 13-3. The adjustment screw 13-2 is rotated, and the adjustment screw 13-2 drives the support plate 13-3 to press against the side of the window sill shear wall, and the second fixed support 12 is fixed to the window sill shear wall using the two support plates 13-3.

[0030] The socket-type plug-in includes a limiting tube 14, which is connected to the first fixed support 1 or the second fixed support 12. A plug 3 is inserted into the limiting tube 14. The cross-sections of the limiting tube 14 and the plug 3 are both set to be square to prevent the plug 3 from rotating relative to the limiting tube 14.

[0031] The installation process of the present invention is as follows: pre-embed bolt holes→install fixed supports→assemble main and secondary trusses→install main and secondary trusses→assemble safety nets→install safety nets→steel wire ropes to pull main trusses diagonally.

[0032] The specific steps include:

[0033] The first step is to reserve bolt holes on the shear wall, use high-strength bolts 2 to fix the first fixed support 1 on the shear wall, and use adjustable supports 13 to fix the second fixed support 12 on the window sill of the window opening;

[0034] Step 2: Use the pin 15 to connect the square plug 3 and the main truss 6 together, insert the steel wire rope 9 into the pulleys 10 and the electric pulley 5 at both ends of the secondary truss 7, insert the square plug 3 at the end of the assembled main truss 6 into the square limit tube 14 of the first fixed support 1 or the second fixed support 12, and place the main truss 6 flat on the fixed support plate 4;

[0036] Step 4: The inclined steel wire rope 18 is fixedly connected to the steel bar ring 11 at the end of the main truss, and the other end is fixed to the upper shear wall. The electric pulley 5 switch is started, and the steel wire rope 9 rotates to pull the steel ring 8 on the secondary truss 7 to move toward the end. The steel ring 8 drives the safety net 16 and the diamond frame 17 to start tensioning. When the safety net 16 is tensioned to the end of the main truss 6, the electric pulley 5 is closed;

[0037] Step 5. After the recyclable safety net protection system is installed, it can effectively prevent the upper materials from falling. When there is a lot of garbage on the safety net, start the electric pulley 5, and the safety net 16 begins to be recovered to the root of the main truss 6 to clean up the garbage on it. After cleaning, start the switch of the electric pulley 5, and the safety net 16 is re-tensioned to the end of the main truss 6.

[0038] The recyclable safety flat net protection system can be quickly installed and dismantled, can be used repeatedly, is easy to operate, has a high safety factor, can reduce the occurrence of potential safety hazards, has beautiful protection, and can meet the requirements of safe and civilized construction.
