construction safety net

2018-06-28

The safety net is a protective net installed below or on the side of a high-rise building construction equipment installation or technical performance to prevent accidents caused by falling people or objects. The safety net consists of a net body, a side rope, a tether and a rib rope. The net body is made of braided ropes and has a diamond or square mesh. Mesh size refers to the distance between two knots adjacent to the braid. The net rope on the edge of the net is called the side rope. The size (nominal size) of the safety net depends on the size of the side rope; the rope that fixes the safety net on the support is called a tether. In addition, ropes used to increase the safety net strength are collectively referred to as tendons.


Safety nets are used to prevent people and objects from falling, or to avoid or reduce the nets of falling and physical damage. Safety nets generally consist of nets, side ropes, and tethers.


The safety net consists of a net body, a side rope, a tether and a rib rope. The net body is made of braided ropes and has a diamond or square mesh. The distance between two knots adjacent to the knitted fabric is called the mesh size; the net rope at the edge of the net is called the edge rope. The size (nominal size) of the safety net is determined by the size of the side rope; the rope that fixes the safety net on the support is called a tether. In addition, ropes used to increase the safety net strength are collectively referred to as tendons. Safety net materials require small specific gravity, high strength, good abrasion resistance, high elongation, and strong durability. In addition, it should have a certain degree of weather resistance, and its strength will not drop too much after dampness and humidity. The safety net is mainly made of chemical fiber. All the nets on the same safety net should use the same material, and the wet strength ratio of all materials must not be lower than 75%. In general, synthetic fibers such as vinylon and nylon are used as mesh cords. Polypropylene is not stable due to its performance and is prohibited from use. In addition, as long as it meets the requirements of relevant international regulations, cotton, hemp, brown and other plant materials can also be used as raw materials. No matter what kind of materials are used, the weight of each safety net should not exceed 15kg, and it must be able to withstand 800N impact force.
