Steel plate type: stair treads, ditch cover, ceiling steel lattice panels, platform steel plate etc..
In 1, at each intersection of load flat steel and rail, through welding, riveting or pressure lock will be fixed.
2, the steel grid plate of the prior use of the welding pressure resistance welding, also can use arc welding.
3, the steel grid plate pressure lock can be used to press the cross bar is pressed into the fixed flat load.
4, the steel grid plate should be based on the needs of users, processed into various sizes of shape.
Spacing of 5 and flat steel bar spacing and load can be determined by the supply and demand according to the design requirements. As an industrial platform, flat load recommended spacing shall not be greater than 40mm, bar spacing shall not be greater than 165mm.
In the end of the load should be used with flat steel, flat steel edging load with the specifications of the flat steel. On special occasions, can be used directly or steel rib plate edge, but the area shall not be less than the sectional area of plate edge load of flat steel. Wrapping with one side welding of high thickness not less than the load of flat fillet weld, the weld length of not less than 4 times the thickness of the flat load. In the edge wrapping plate is not under load conditions, allowed a 4 flat welding load, but the spacing shall not be greater than 180mm. In wrapping plates subjected to loads, and must not allow interval welding, full welding.
Stair treads the end edge of one side welding plate must be full of. With the load to the same edge flat plate, and each must be welded rails. Steel plate in the incision, open hole is equal to or greater than 180mm, should be the edge processing.
If the front edge stair step plate plate, must through the whole time.
The load of flat steel grid plate, the plane flat steel, flat steel or I type longitudinal shearing strip. The load of flat steel grid plate, a tooth type, in order to increase the steel grid plate slip force, tooth size as shown in figure 2. In each 100mm can not be less than 5 teeth. The minimum width of the steel grid plate on the gear type size platform shall not be less than 300mm.
