As shown in fig. 3, for the assembly process of the present invention, specifically, it is:

the first step is to assemble the uprights and diagonals using M12 x 90 bolts and lock nuts.

And secondly, mounting the square-round connecting piece and the double-connecting joint at the upper ends of the vertical rod and the diagonal rod respectively.

And thirdly, controlling the distance between the two groups of vertical rods, wherein the distance between the safety nets with the width of 6m is 4 +/-0.5 m, and the distance between the safety nets with the width of 4.2m is 2 +/-0.5 m.

And fourthly, penetrating the inner side and outer side locking steel pipes into two long edges of the safe anti-falling net.

And fifthly, fixing the safety anti-falling net at the tail ends of the inner and outer side fore shaft steel pipes by using a spring fastener to avoid sliding out.

And sixthly, fixing the inner and outer side locking steel pipes which are penetrated with the safe anti-falling net surface on the vertical rods and the inclined rods through the square-round connecting pieces and the double-connecting joints.

And seventhly, installing the upper telescopic piece and the lower telescopic piece on the vertical rod.

As shown in fig. 4, the process of installing the assembled grid structure on the building specifically includes:

the method comprises the following steps: and hoisting the assembled safety net rack to the installation position by using a tower crane.

Step two: and fixing the plate surface connecting piece of the upper telescopic piece of the upright rod on the floor slab by using a bolt.

Step three: and fixing the wall surface connecting piece of the lower telescopic piece of the vertical rod on the vertical outer side surface of the next floor slab by using bolts.

Step four: and (3) completing the installation of the overhanging type safe anti-falling grid structure, continuing the steps of assembling and installing, and installing other required overhanging type safe anti-falling grid structures on the building.

Because whole anti-falling net rack weight is lighter (about 84kg), can install with the help of hoisting equipment cooperation such as tower crane for the first time, later stage demolish transfer to above floor, only need the manual work with the help of the rope promote can.

The utility model discloses a demolish the flow and specifically do: firstly fixing a safety rope → dismantling an edge protective fence → removing a nut of a lower part of an upright post → drawing the net in the direction of an inward side locking steel pipe → clearing falling objects on the net body → loosening the inner side locking steel pipe fixing piece → rolling the net and tightly binding with a rope → loosening an upper part fixing piece of an inclined rod and temporarily fixing with an upper opening of the upright post → hanging the rolled net body (containing two locking steel pipes) with the rope → removing a fixing bolt nut of the upper opening of the upright post → hanging the upright post with the rope, the inclined rod → recovering the edge protective fence → dismantling the safety rope (completing the dismantling work).

The repeated installation process specifically comprises the following steps: fixing a safety rope → installing and fastening telescopic connecting piece fixing bolts at the upper part and the lower part of the vertical rod → loosening the upper opening of the oblique rod, fixing the telescopic connecting piece fixing bolts with the outer side locking steel pipe of the safety anti-falling net → fixing the inner side locking steel pipe of the safety anti-falling net with the upper opening of the vertical column → loosening the outer side steel pipe of the safety anti-falling net for slowly releasing the net until the safety anti-falling net is tightened → recovering the adjacent edge protective fence → dismantling the safety rope (the installation work is completed).

During the whole process of dismantling and reinstalling, the safety belt of an operator must be tied and hung on the safety rope, and if the height of a floor is adjusted, the safety belt is adjusted through the adjusting hole between the inclined rod and the upright post until the angle and the height are reasonable.

In order to further improve the protection between adjacent safety and protection components, in a plurality of groups of safety and protection components arranged outside the building, the safety and protection nets 5 in the adjacent safety and protection components are connected together or have an overlapping part.

As shown in figure 5, the adjacent safety anti-falling nets 5 are connected by adopting connecting ropes 9, the connecting ropes 9 penetrate into meshes of net surfaces of the adjacent safety anti-falling nets 5 to bind the adjacent safety anti-falling nets 5 together, and the distance between the adjacent safety anti-falling nets 5 is smaller than 100 mm.

As shown in fig. 6, the adjacent safety anti-falling nets 5 are overlapped in a staggered manner, that is, an upper net is installed between two lower nets, and two ends of the upper net are respectively overlapped with the corresponding lower nets.

As shown in figure 7, the adjacent safety anti-falling nets 5 are overlapped continuously, namely, each safety anti-falling net 5 forms an equidirectional inclined state after being installed, the adjacent safety anti-falling nets 5 are overlapped continuously in sequence, and the inclined states of the safety anti-falling nets 5 are formed by the installation positions of the corresponding upper telescopic pieces 3 at different heights.

When the two modes of up-and-down staggered overlapping and continuous overlapping are used, the length of the overlapping part of the net surface of the safety anti-falling net is ensured to be more than 0.75 meter. Because the mesh surface is usually narrowed in the middle, the long sides of the mesh surfaces of the two sets of safety nets, namely the overlapping length of the steel pipes at the locking openings, generally reach 1 meter if the overlapping part of the mesh surfaces reaches 0.75 meter.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
