Precautions for installing clamps on hot-dip galvanized steel grating: Fixing methods of hot-dip galvanized steel grating: There are two methods of fastening: welding and installing clamps. The advantage of welding is that it is permanently fixed and will not loosen. The advantage of installing clamps is that it will not loosen. It is easy to damage the hot-dip galvanized layer and disassemble it. The safest way is to directly weld the screw heads to the beam without clamping, to ensure that the hot-dip galvanized steel grating will not slip from the beam due to the loose installation clamp. Welding fixation is suitable for parts that do not need to be disassembled permanently. , such as the channels around the equipment, and the use of installation clamps has the characteristics of not damaging the zinc layer and being easy to disassemble.
The installation clamp is suitable for various series of hot-dip galvanized steel gratings. It consists of an upper clamp, a lower clamp and M8 or M10 hexagonal cylindrical head bolts. The welding and fixing method is: install one at each corner of the hot-dip galvanized steel grating. On flat steel, the weld should be no less than 20mm and the height should be no less than 3mm for fillet welding. Use the method of fixing with installation clamps: Use at least four sets of installation clamps for each board. For plates with larger spans, it is best to install several more on available supports. They consist of an upper plate with double hooks and a toothed one. It consists of a lower pressure plate and an M8 hexagon socket bolt.
It consists of an upper pressure plate with double grooves (a hook can hold two adjacent hot-dip galvanized steel gratings together), a lower pressure plate with teeth and an >M8 internal angle bolt. It consists of the upper pressure plate of the groove and an M8 hexagonal head bolt that can be welded to the supporting member. Directly weld the hot-dip galvanized steel grating or step boards to the supporting steel structure. Paint the welding area twice with zinc-rich silver paint. Use a special device clamp for the Yangtze River Delta hot-dip galvanized steel grating to avoid damaging the galvanized layer. Disassembly and assembly convenient. Each set of device clamps includes an upper clamp, a lower clamp, an M8 round head bolt and a nut. Fastening methods such as stainless steel installation clips or bolt connections can be selected according to needs. The installation gap of hot-dip galvanized steel grating is generally 10MM.
When installing, you must pay attention to whether the installation is strong and reliable. You should check it frequently to prevent the installation clamp from loosening and falling. It is best to weld or add rubber pads to the hot-dip galvanized steel grating close to the vibration source. Use the required movable and detachable platform for the installation clamp. Hot-dip galvanized steel grating must be fixed with special fixtures for hot-dip galvanized steel grating to avoid any displacement of the component. Installation clamps can be supplied by the manufacturer according to the requirements of the demander. Except for installation clamps made of stainless steel, installation clamps made of carbon steel must be hot-dip galvanized. It is recommended that the bolts used for the installation clamp be hot-dip galvanized. The diameter of the bolts must not be Less than 8mm. The number of installation clamps used for each hot-dip galvanized steel grating shall not be less than 4. For plates with larger spans, it is best to install several more on available supports.
