Galvanized hook mesh selection of low carbon steel wire, the surface of cold galvanized or hot galvanized anti-corrosion treatment, the net wire is strong, strong protection, long anti-corrosion time. Galvanized wire hook mesh is widely used in warehouses, east-west refrigeration, protective reinforcement, parks, zoo fences, Marine fishing fences and construction site fences, mechanical equipment protection.
There are two kinds of wire factory, namely slope protection hook net, coal mine hook net, mine hook net, coal mine support net, roadway support net, etc. The height of sidewalks or seatbelt outer railings should not be less than 1.10 meters. The net distance between the railings should not be greater than 140 mm, and horizontal bar rails should not be used. The planning of the hook mesh is necessary to be safe and reliable, the anchor rod should be installed on the basis of the railing, and its strength should meet the requirements of the standard.
The strength of the hook mesh should be satisfied: when the vehicle is traveling at a speed of 80 kilometers per hour, the hook mesh will not fall into the river when it bumps against the railing at a 15 degree Angle. The shape and color of the mesh should be harmonized with the surrounding natural environment. The phenomenon planning of the important Bridges should be done well.
When the bridge crosses important traffic lines, such as expressways, urban rail transit, expressways, railway trunk lines, etc., the hook mesh should be added to the protective net on the pavement of the bridge deck. The height of the shield should not be less than 2 meters. The length of the shield should be the width of the journey and an extension of 10 meters away.
The vertical load of the handrail on the bridge is 1.2KM/m; The horizontal external load is 2.5KM/m, and both should be accounted for separately. Galvanized hook mesh belongs to a hook mesh, it is the selection of electric galvanized wire, hot-dip galvanized wire as raw materials, through the hook mesh ginning cut weaving.
