The steel grid plate is a kind of anti-skid marine grid with economical development and simple structure, including a fixed frame and a large-sized flat steel and cross bars in a fixed box-type filter press unit; the flat steel is perpendicular to the The azimuth is tilted. When the flat steel is inclined, when walking on the marine grating, the total contact area between the foot plate and the flat steel is larger, which can reasonably expand the sliding friction force, so that the inclined flat steel can play the role of inverted teeth when walking, avoiding the Drag on the foot plate under exertion. In order to avoid dragging when walking on the marine grating, it is best to tilt the adjacent two pieces of flat steel in opposite directions. In order to prevent the bumpy condition of the cross bar protruding from the upper surface layer of the flat steel, the maximum height of the cross bar is less than the aspect ratio of the flat steel or flush with the flat steel. The utility model has a simple structure, reasonably increases the total contact area between the foot plate and the flat steel, reasonably increases the sliding friction force, and has a practical anti-skid effect. Foot drag.
After using the hot-dip galvanized steel grid frame, you should pay attention to:
1. Clean up the garbage scattered on the surface of the steel grid in time, especially the pollutants with corrosive properties, and try to ventilate the surface of the steel grid.
2. When installing the steel grid frame, it can be installed with steel grid mounting clips. The advantage of installing a fixed steel grid is that it will not damage the anti-corrosion layer on the surface of the steel grid. However, it is necessary to regularly check the steel frame installation clips, especially whether the screws of the steel frame installation clips are loose, and if they are loose, they should be tightened immediately. A routine inspection every other month is recommended. For steel grid platforms and other places where people and vehicles often pass by, the time for regular inspections should be shortened.
3. The steel grating is generally fixed by welding. The advantage of welding and fixing is that the installation is convenient and simple, which can save a lot of trouble. However, after the steel grating is installed and welded, attention should be paid to painting the same color anti-rust paint on the welded joints. Attention should also be paid to avoid corrosion of the steel grating from the weld, and the antirust paint at the welded joint should be checked regularly. If the anti-rust paint falls off, the previous anti-rust paint must be sanded off and reapplied.
4. The anti-rust paint used by frequent use is easy to rub and fall off, and the anti-corrosion layer should be repaired to increase the service life of the steel grating.
5. For the steel grating that needs to be bolted, especially the steel ladder ladder, the bolt inspection should be carried out regularly to avoid the danger of bolt loosening. After installing the bolts, spray another layer of anti-rust paint on the bolts.
6. If there are hidden dangers such as virtual welding and missing welding at the welding place of the steel grating, repair welding should be carried out immediately, and anti-rust paint should be sprayed after the repair welding is completed.
7. If you find that the steel grating is damaged, such as deformation caused by serious damage, you should immediately contact the manufacturer for a replacement to avoid danger.
