FRP grating is a grid structure, which has good characteristics of wear resistance, corrosion resistance and high temperature insulation and anti-static. It can often be seen in daily life. Sometimes we will see cracks, blocks, and compression during use. Failure, then what is the cause of these problems, and how can we avoid this phenomenon and extend the service life of the grille panel?
In view of the phenomenon that the glass fiber reinforced plastic grid plate is dropped, it is necessary to check whether the glass fiber reinforced plastic grid plate is laid upside down. When the grid plate is laid, it must be divided into front and back sides. This design is based on the principle of arch mechanics, so you only spread the thick side of the wall into an inconspicuous arch surface, so the stress of the FRP grid will be better. If you lay it upside down and become a half-moon garden, the weight is squeezed on it, which will destroy its mechanical principle, so the quality of the FRP grid will be affected.
In view of the cracks in the use of FRP grille, check whether the actual span of the trench is too large. Generally, whether it is 38 or 50 grille panels, if the vehicle is passed for a long time, the maximum span of the trench should not exceed 50 kg. Generally, the manufacturer recommends that the net span of the trench is within 35 cm, so as to ensure that the service life of the grille panel is longer.
In view of the phenomenon that the glass fiber reinforced plastic grid plate is crushed, if it is not the above situation, then the grid plate has to be replaced. In order to save costs, the board can be divided into two by a polisher, and the bad part is thrown away. The remaining good grid The grid can be reused.
The full penetration of the glass fiber reinforced plastic grid plate through the interweaving of fiberglass weaving and resin makes the grid have good corrosion resistance. The overall layout will evenly distribute the load, which will help the grid device and its supporting layout to be uniformly stressed. In daily use, the specifications must be strictly determined according to the load requirements. The load capacity of the grid plates of different specifications and performances is different. Remember that the grid cannot be overloaded during use, and the grid must be fully supported, and the foundation should meet the grid installation requirements, otherwise the load capacity of the grid will not be achieved.
