Abstract

The invention relates to a method for assembling a large-area safety net. The method comprises the following steps: 1) building a row of floor type cross scaffolds in the center of an assembly hall; 2) assembling a steel wire rope and a counterweight, wherein one end of the steel wire rope is fixed with a central scaffold pole through a U-shaped buckle, while the other end is towed to the outside of a main body structure through a small hoist to drop to the ground, and the tail end suspends the cement counterweight; 3) sleeving a side rope of the safety net on the stretched steel wire rope by using a safety clasp; 4) binding a hemp rope at the upper end of the side rope of the safety net, and towing the upper end of the safety net to the central scaffold pole by a hemp rope through a fixed pulley; 5) binding and fixing the hemp rope with the central scaffold after the safety net is in place; and 6) binding and fixing the side rope between adjacent net pieces with the steel wire rope in the center from the top to bottom. Compared with the prior art, the method has the advantages of solving the problems of stretching and suspending the safety net under the condition of not building the scaffold and the like.

Description

A kind of method for assembling large-area safety net

Technical field

The present invention relates to the safety net mounting method, especially relate to a kind of method for assembling large-area safety net.

Background technology

Safety net is to be used for preventing that people, thing from falling, perhaps be used for avoiding alleviating falling and object strike injury, be divided into plain net, upright net and dense mesh type safety net, the safety net regular size is wide 1.8 meters, and 6 meters of length are generally used the dense mesh type safety net now, the standard of dense mesh type safety net: 2000 above meshes are arranged in 100 sq, anti-piercing test, net become 30 degree angles with ground, 5 kilograms of φ 48MM steel pipes freely fall and can not penetrate at 3 meters height places.The connection of conventional safety net is spliced by nylon rope, must be fixed on the scaffold, and it is many that fixed point is wanted, and assembled safety net occurs splicing not firm and the generation potential safety hazard easily.

Summary of the invention

Purpose of the present invention is exactly to provide a kind of method for assembling large-area safety net for the defective that overcomes above-mentioned prior art existence.

Purpose of the present invention can be achieved through the following technical solutions:

A kind of method for assembling large-area safety net is characterized in that, this method may further comprise the steps:

1) sets up row in the central authorities that the hall is installed and land well word scaffold;

2) wire rope and counterweight are installed, described wire rope one end is buckled with the central scaffold bar by the U type and is fixed, and the other end draws by small winch and hangs down to agent structure to ground, terminal suspention cement counterweight;

3) safe selvage rope with safe retaining ring on the good wire rope of stretch-draw;

4) upper end of described safe selvage rope is tied with the rope made of hemp, and the rope made of hemp is drawn to central scaffold bar place by fixed pulley with the safety net upper end;

5) safety net is fixing with the binding of the rope made of hemp and central scaffold after in place;

6) from top to bottom the rope of the limit between the adjacent net pieces is fixed with the wire rope colligation from central authorities.

Described step 2) wire rope in is 50～65.

Described step 2) the cement counterweight in is 6～10, and gross weight is 2000kg.

Spacing between the safety button in the described step 3) is 800～1200mm.

Safety net is the special Dense mesh screen of 10000 * 70000mm in the described step 3).

Compared with prior art, the present invention has the following advantages:

1, problem is hung in the stretch-draw that has solved safety net under the situation of not setting up scaffold, prevent decoration construction up and down the personnel's injury accident and the article that are caused of the contingent falling object from high altitude of interchange operation damage.

2, because the space is bigger, the stock size safety net can't the covered protection construction area, adopts large-area safety net, guarantees to cover and puts in place.

Description of drawings

Fig. 1 is the structural representation after the installation of a kind of method for assembling large-area safety net of the present invention.

The specific embodiment

The present invention is described in detail below in conjunction with the drawings and specific embodiments.

Embodiment

As shown in Figure 1, the furred ceiling center in hall is installed does not have the safety net fixed point, be provided with the double well word scaffold that lands in that central authorities mast 1 place, hall is installed, be mainly used in fixedly wire rope and hang close order safety net.

Wire rope 2 and counterweight are installed, at depression bar position, central mast 1 side installation length is 58 of the wire rope of 85000mm, one end is buckled with the U type around one week of depression bar and is fixed, the other end draws to cornice agent structure outer-ring beam 4 places by small winch and hangs down to ground, lower end suspention cement counterweight 3, totally 8 of every counterweight 250kg, the lifting of employing electric block, after the arrival specified altitude assignment that wire rope 2 lower end reflexed 650mm are long, buckle admittedly reliably connection with the U type, every position is established three U types and is buckled, and meets the requirement of stretch-draw intensity.The installation of safety net is drawn to central mast place by low, safety net is the special Dense mesh screen of 10000 * 70000mm, safe selvage rope with safe retaining ring on the good wire rope 2 of stretch-draw, safety button spacing is 1000mm, the upper end with the rope made of hemp by fixed pulley with the manpower traction to central mast 1 place, the two ends of safety net parallel traction simultaneously during traction, on average exert oneself in the attention both sides, in order to avoid owing to unbalance stress causes buckle, the limit rope is stuck with wire rope, after safety net is in place that rope made of hemp bolt is also fixing on mast, after safety net is in place, adopt the self-control cage to utilize manpower traction's cage to move down and colligation safety selvage rope from last (central mast place), the rope of the limit between the adjacent net pieces is firm with the wire rope colligation.Wire rope requires that sufficient intensity, rigidity and stability are arranged, and is that the net place does not have sharp edges.

Do impact experiment and piercing test after safety net is set up and finished on request, test and to come into operation after qualified.
