When the construction site is installed, a worker firstly fixes the vertical rod 11 on the outer wall, then installs the opposite sides of the safety flat net 4 on the vertical rod 11 and the inclined stay rod 12 respectively, and finally rotates the inclined stay rod 12 in a direction away from the wall surface, and the safety flat net 4 is unfolded in the horizontal direction; in the process that one end of the diagonal brace 12 is far away from the wall surface, the included angle between the first limiting rod 131 and the second limiting rod 132 is increased, when the included angle between the first limiting rod 131 and the second limiting rod 132 is increased to 180 degrees, the axis of the first limiting rod 131 and the axis of the second limiting rod 132 are parallel, and one end of the diagonal brace 12 cannot be far away from the wall surface continuously; the whole safety support is opened to a maximum state, and the safety flat net 4 is opened at this time, so that accidents caused by falling of people or objects are reduced. By utilizing simple field work, workers can finish installation by standing in the building wall body without suspending operation, and potential safety hazards in the installation process of the safety flat net are reduced.

Referring to fig. 1, the mounting bracket is further provided with an inner cross bar 21 and an outer cross bar 22, the inner cross bar 21 is fixed on the vertical bar 11 through the clip 14, and the outer cross bar 22 is fixed on the diagonal brace 12 through the clip 14; the inner rail 21 and the outer rail 22 are fastened by bolts after being snapped into openings in the clamp 14. In this embodiment, the safety flat net 4 is sewn with sleeves on one side close to the wall surface and the corresponding side parallel to the wall surface, and the inner cross bar 21 and the outer cross bar 22 pass through the sleeves and are exposed at two ends and are clamped into the clamping hoop 14.

When the safety flat net 4 is installed, a worker firstly penetrates the inner cross rod 21 and the outer cross rod 22 into sleeves corresponding to two sides of the safety flat net 4 respectively, then installs two ends of the inner cross rod 21 and the outer cross rod 22 exposing the safety flat net into the clamp 14, screws bolts to fasten the clamp 14, and finally rotates the diagonal brace 12 in a direction away from a wall surface, and the safety flat net 4 is unfolded in the horizontal direction; when the safety flat net 4 needs to be cleaned and checked, a worker pulls the safety flat net 4 at the vertical rod 11 to enable one end of the diagonal brace 12 to rotate to the side close to the wall surface, when the diagonal brace 12 is attached to the vertical rod 11 again, the safety bracket is closed to be in a minimum state, bolts on the clamp 14 are screwed to be capable of being taken down, the inner side cross rod 21, the outer side cross rod 22 and the safety flat net 4 are taken down together, and dropped articles are cleaned.

Referring to fig. 2, a pull rope 3 is arranged on the mounting bracket, a limiting block 31 and an anti-slip layer 32 are arranged on the pull rope 3, the length of the pull rope 3 is larger than the projected length of the safety flat net 4 in the direction perpendicular to the wall surface, and an opening 111 and a fixing pile 112 are arranged at the top end of the vertical rod 11. One end of the pull rope 3 is fixed on the diagonal brace 12 by winding and knotting, and the other end of the pull rope passes through the opening 111 to protrude out of the vertical rod 11 and is wound on the fixed pile 112; a limiting block 31 is fixed on the pull rope 3 through gluing, the diameter of the limiting block 31 is larger than that of the opening 111, and the limiting block 31 is positioned at one end of the pull rope 3 far away from the diagonal brace 12; in this embodiment, the pull rope 3 is a hemp rope, a layer of anti-slip layer 32 with the same rotation direction and shape as the pull rope 3 is wound on the pull rope, the anti-slip layer 32 is nylon adhesion, one side with a binding sense is exposed, and the limiting block 31 is positioned between the anti-slip layer 32 and the fixing pile 112.

In the unfolding process of the safety flat net 4, the top end of the inclined stay bar 12 drives one end of the stay rope 3 to be away from the wall surface, and when the safety flat net 4 is completely opened, a limiting block 31 connected to the stay rope 3 is abutted to the vertical rod 11, so that the stay rope 3 is prevented from falling off. When the safety flat net 4 needs to be cleaned, a worker holds the anti-slip layer 32 on the pull rope 3 at the vertical rod 11 to increase friction and pulls the anti-slip layer to the wall to drive the inclined stay bar 12 to rotate towards the direction close to the wall surface until the inclined stay bar 12 is attached to the vertical rod 11; at this time, the worker tightly winds and fixes the protruding part of the pull rope 3 passing through the opening 111 on the fixed pile 112 so as to lock the diagonal brace 12, so that the diagonal brace cannot rotate any more, and removes the safety flat net 4 for cleaning; after the cleaning is completed, the worker installs the safety flat net 4 back to the original position, loosens the pull rope 3 wound on the fixing pile 112, and repeats the above steps to unwind the safety flat net 4.

The implementation principle of the installation support of the safety flat net is as follows: when a worker installs the safety flat net 4, a group of prefabricated support assemblies 1 are conveyed to a required position and are fixed on an outer wall in the vertical direction parallel to the wall surface through vertical rods 11; the inner cross bar 21 and the outer cross bar 22 are respectively penetrated into sleeves corresponding to the two sides of the safety flat net 4, then the two ends of the inner cross bar 21 and the outer cross bar 22 exposed out of the safety flat net 4 are installed in the clamp 14, and the clamp 14 is fastened by screwing bolts; rotating the diagonal brace 12 in a direction away from the wall surface, and expanding the safety flat net 4 in the horizontal direction; the first limiting rod 131 and the second limiting rod 132 rotate along with the outward rotation of the diagonal brace 12, and when the included angle between the first limiting rod 131 and the second limiting rod 132 reaches 180 degrees, the safety flat net 4 is completely unfolded to reach a working state;

when falling objects are arranged on the safety net, a worker holds the anti-slip layer 32 on the pull rope 3 to pull the wall body, and drives the diagonal brace 12 to rotate towards the direction close to the wall surface until the diagonal brace 12 is attached to the vertical rod 11; at this time, the worker winds and fixes the pull rope 3 around the fixing pile 112 through the protruding portion of the opening 111 to lock the diagonal brace 12 from rotating any more; turning the bolts on the clamp 14 to be removable, and removing the inner cross bar 21, the outer cross bar 22 and the safety flat net 4 together to clean the dropped articles; after the cleaning is completed, the safety flat net 4 is unfolded by repeating the steps.
