Main technical performance indicators of building safety net (GB5725-2009)

1. Side rope strength ≥7000N

2. Strength of tendons and ropes≤3000N

3. The distance between the adjacent two bars and ropes is 750mm≥P≥300mm, and the distance between the adjacent two ropes is ≤750mm

4. Impact resistance: 100kg iron ball, impact height of 7 meters, continuous net, edge and tether.

2. Specifications and requirements for building safety nets

1. Specification model: P-3×6

2. Mesh shape and side length: diamond mesh ≤ 80mm

3. Weight (each flat net)≤15kg

3. Installation and dismantling of building safety net

When installing, the installation plane of the flat net is parallel to the horizontal plane, and the binding is firm. When installing, it should be firmly tied to the frame rod, and it should conform to the principles of convenient knotting, firm connection and easy disassembly.

When dismantling, pay attention to:

1. Only after the operation of the protection area is stopped, can it be removed;

2. Demolition should be carried out under the close supervision of relevant personnel.

3. Relevant fall measures should be taken according to the site conditions during dismantling.

Fourth, the use and maintenance of building safety net and matters needing attention

1. The following phenomena must be avoided when using the flat net:

①Drag on rough or sharp-edged (corner) surfaces;

②There is serious corrosive smoke around the flat net;

③ A large number of welding sparks fall into the flat net.

2. The flat net should be checked at least once a week during use, and it should be repaired or replaced in time when the following conditions are found:

① Serious deformation or wear;

②Break or hole;

③ The tether is loose and the lap joint is disengaged

3. The flat net is allowed to be repaired during use, and the strength after repair is not lower than that of the original flat net, and it can continue to be used after passing the inspection by a special person.

4. The attachments close to the flat screen should be removed frequently to keep the flat screen clean.

5. The use period of Pingwang is 12 months.

Construction safety net use: It is mainly used to prevent people and objects from falling, or to avoid and reduce the damage of falling objects, to protect the safety of workers and pedestrians at heights, and to maintain the cleanliness of the site.
