Loading type glass fiber reinforced plastic grille panel

Abstract

The invention discloses a loading type glass fiber reinforced plastic grille panel. The loading type glass fiber reinforced plastic grille panel comprises an upper core plate and a lower core plate, wherein a plurality of first T-shaped supports are arranged on the upper surface of the upper core plate, a plurality of second T-shaped supports are arranged on the lower surface of the lower core plate, a lug is arranged on the upper surface of each first T-shaped support, and a raised line is arranged on the lower surface of the first T-shaped support. The loading type glass fiber reinforced plastic grille panel has the advantages that the structure is reasonable, the load coefficient is high, the bearing pressure is high, transportation is convenient, the safety coefficient is high, the production cost is low, the working efficiency is high and the grille panel cannot be damaged easily.

Description

technical field [0001] The invention relates to a load-type glass fiber reinforced plastic grid plate. Background technique [0002] The grid plate is a kind of steel product with a square grid in the middle, which is made of flat steel cross-arranged according to a certain interval and cross bars, and welded by a pressure welding machine or manually to form a square grid. The grid plate is mainly used as a drain cover , steel structure platform plate, steel ladder tread plate, etc., the cross bar generally adopts twisted square steel. [0003] There are two methods of making grid plates: machine pressure welding and hand-made. [0004] Machine pressure welding uses a high-voltage resistance pressure welding machine. The manipulator automatically places the crossbars horizontally on the evenly arranged flat steel, and press-welds the crossbars into the flat steel through strong electric welding power and hydraulic pressure, so that the solder joints can be strong. High-qua...

Problems solved by technology

[0010] The disadvantage of FRP is: low elastic modulus

Aging phenomenon is a common defect of plastics, and FRP is no exception. It is easy to cause performance degradation under the action of ultraviolet rays, wind, sand, rain, snow, chemical media, and mechanical stress.

low shear strength

The interlayer shear strength is borne by the resin, so it is very low
