Abstract

The present invention relates to a high-load water grate, grate cover including water, the water phase matches the water grate with grate cap base; said water seat cover grate square hollow structure, an end cap body and said water grate water grate cover hinged seat and snapped in water grate cover seat; the water grate cover comprises two lateral longitudinal reinforcement and reinforcement, the two lateral longitudinal reinforcement and intersecting each other perpendicularly arranged as a reinforcement; unidirectional insert in the form of destruction of the material itself flatness, and then recombining material, greatly increasing the structural integrity of the high load water grate increase the strength, Further, the W-SMC was cut into a water grate shape, hemispherical shaped body, greatly improves the rigidity and strength of water grate, can withstand the maximum bearing pressure suffered very center, but also increases the overall coefficient of water grate carrier.

Description

technical field [0001] The invention relates to an urban planning and construction equipment, in particular to a high-load water grate. Background technique [0002] SMC is the abbreviation of Shui Bi water grate, that is: unsaturated resin as the base material reinforced with glass fiber sheet molding compound. The main raw materials of SMC sheet reinforced plastics include SMC special yarn, unsaturated polyester resin, epoxy vinyl resin, low shrinkage additives, fillers and various auxiliary agents. SMC materials have the advantages of superior electrical properties, corrosion resistance, light weight and easy and flexible engineering design. Because its mechanical properties are comparable to some metal materials, it is widely used in aerospace and aviation aircraft (carbon fiber reinforced cabin), railway vehicles, automobiles, railway and highway facilities, military facilities, sports facilities, construction, electronic accessories, electrical, etc. in the industry....
