With the increasing use of hook mesh, the method of bridge rail is also different. The height of the outer railing of the walkway or seat belt should not be lower 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, and the horizontal external load is 2.5KM/m, both of which should be calculated 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.
Galvanized hook mesh standard is thorough, mesh planning: 3cm-20cm, wire planning: 1.2mm-4.5mm, galvanized hook mesh 6000 square meters, some standards are in stock. Benefits: The selection of low carbon steel wire, the surface of cold galvanizing (electric galvanizing) hot dip galvanizing 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. Among them, there are two kinds of use, namely, slope protection hook net (slope protection net), coal mine hook net (mine hook net, coal mine support net, roadway support net).
