In the construction of supporting plate of steel grid structure, we need to choose the thickness of steel plate, so how to choose the thickness of building bearing plate? Let's introduce it in detail. How to select the thickness of bearing plate of steel lattice structure in the construction process?
The thickness of the floor slab is generally selected according to the design requirements, which is mainly related to the span between steel beams. For the bearing plate of steel frame structure, the spacing between steel beams is generally no more than 3m, and the crotch of many main frames of steel structure is more than 5-6m. At this time, it is necessary to add secondary beams, which are supported under angle steel, slot wind, or building support plate, that is, the spacing between beams is no more than 3m in any case. For example, in some small buildings, such as private houses and steel office buildings, when using 0.a8mm floor slab, the normal distance between steel beams is only 1 to 2 meters, or even less than 1 meter.
For ordinary steel structure workshop, the spacing of steel beams is generally between 2-3m, and the spacing of 2-2.5m can adopt the floor above 1.0mm and the closed floor above 2.5m. On the floor of 1.2mm, these thicknesses can basically hide the construction requirements of ordinary steel structure. Of course, we refer to the parameters of other places in China.
