The workshop can be constructed in many forms and ways. Nowadays, the most common one is the steel structure workshop, which mainly takes the steel structure as the main load-bearing structure, the wall can be brick concrete structure or steel structure, most of which are made of color plates, and then the workshop composed of doors, windows and other components. Due to the increase of steel output in China, many light steel workshops are used, and steel structures are mostly prefabricated in factories, which can reduce the construction amount and cost.
Among them, the light steel plant is not only light in weight, low in steel consumption and fast in construction, but also has strong seismic capacity and can improve the comprehensive seismic performance of the whole building. It is a structure widely used in industrial plant at present.
Light steel structure is composed of foundation beams, columns, purlins, floors and walls. Single story light steel plants generally adopt portal steel frame. Portal steel frame creates conditions for long slope drainage in large span steel structure plants. Setting intermediate columns can reduce the span of beams and reduce the cost. The middle column is made of steel tube and hinged swing column, which takes up little space. The lateral rigidity of the portal steel frame is guaranteed by purlin support, the longitudinal rigid members are omitted, and the flange width is reduced. The steel frame can adopt variable section, which is proportional to the bending moment; when changing the section, the height and thickness of web and the width of flange can be changed according to the needs, so as to make the best use of the materials.
The webs of the steel frame of the light steel workshop can be designed according to the effective width, that is to say, some webs are allowed to lose stability and their post buckling strength can be used. Vertical load is usually the design control load, but when the wind load is large or the house is high, the role of wind load should not be ignored. In the light roof portal frame, the seismic action generally does not play a controlling role. Support can be made lighter. It can be connected to web directly or with horizontal gusset plate, and the tensioned round steel can be used. All structural components can be manufactured in the factory with high industrialization degree. The component units can be divided according to the transportation conditions. The units are connected by bolts on the site. The installation is convenient and fast, and the amount of civil construction is small.
The composition of the light steel workshop is inseparable from the factors of beams, columns, roof trusses, roofs, foundations and other parts. The composition of the light steel structure workshop is mostly the same as that of the ordinary steel structure workshop. Because many building structure types are relatively similar, but there are great differences in the materials or other structural components. Light steel structure workshop is a common building in many industrial workshops, so the relevant technology has become mature. I believe that the use of light steel structure will be more and more extensive in the future.
