[0002] Steel grating is also called steel grid. The grid is a steel product made of flat steel arranged crosswise at a certain spacing and crossbars, and welded into a square grid in the middle. It is mainly used for ditch covers, steel structure platform plates, steel ladder treads, etc. The crossbars are generally made of twisted square steel. Composite steel grating has the characteristics of high strength, light structure, and easy maintenance, so it is widely used by people. At present, most of the existing composite steel gratings on the market are welded to the steel grating by welding the composite plate, which not only wastes materials, but also is cumbersome to disassemble and assemble. Therefore, there is an urgent need for a composite steel grating that is easy to disassemble and assemble.

[0003] Chinese patent document CN212668594U discloses a composite steel grating that is easy to disassemble and assemble. By inserting a pin into a card hole, a spring arranged in a fixed rod drives a movable rod to drive the card pin into the steel grating frame, so that the steel plate and the steel grating frame can be flexibly disassembled and assembled, reducing labor consumption.

[0004] To save costs, the steel plate and steel grating frames can be placed on the surface of the fixed screw ring and the support ring, and then the movable screw ring can be used to rotate on the threaded head to fix the steel plate and steel grating frames, and then the serial rod base can be fixed to the ground to prevent the steel plate and steel grating frames from shaking or even falling during loading and transportation, causing safety accidents.

[0005] The existing technology has the following problems:

[0006] Although the above-mentioned composite steel grating can disassemble and assemble the steel plate and the steel grating frame, reducing labor consumption and saving costs, during use, springs are used for assembly, which reduces the overall strength of the plate and thus affects the service life of the plate. In addition, the thermal insulation performance of the composite steel grating is poor. Utility Model Content

[0031] The composite plate assembly 3 is placed on the steel grating frame 1 so that the cross groove 54 is plugged into the cross block 53, which makes it easy to disassemble and assemble the composite steel grating. There is no need to use springs for assembly, which improves the overall strength of the composite steel grating and extends its service life. Through the coordination of the composite plate 31, the PVC plate 32, and the sealing steel belt 33, the composite steel grating has the functions of heat preservation and flame isolation. Through the porous structure of the rock wool 34, the composite steel grating has a sound absorption effect, thereby improving the durability of the composite steel grating.
