>In steel structure engineering, steel structure platforms are widely used. Steel structure platforms generally consist of decking, primary and secondary beams, columns, inter-column supports, as well as ladders, railings, etc. The design and layout of the steel structure platform should meet the following requirements:

< r: >,
: : R> When determining the plane dimensions, elevation, beam grid and column grid layout of the steel structure platform, in addition to meeting the usage requirements, the layout of the beams and columns should also consider the platform. equipment loads and other large concentrated load locations, as well as the hanging of large-diameter industrial pipes, etc.
< r> >
: : R>. The layout of the steel structure platform should be economical and reasonable, and the force transmission should be direct and clear. The layout of the beam grid should be suitable for its span. When the span of the beam is larger, the spacing should also be increased. Make full use of the allowable span of the decking and rationally arrange the beam grid to achieve better economic results.
< r: >,
: : R>Wherever possible, the beams and plates of the platform should be directly supported on factory columns, large equipment or other structures as much as possible to achieve economical purposes.
< r: >,
