The main purpose of the steel structure is to build a steel structure house, the general steel structure houses are mostly to increase the construction area. Or temporary living, and shelter. Therefore, city building roof, and most Street Park gate. The town is more of a steel cottage. Use as a storage or temporary housing.
1 the mechanical properties of the steel structure make the sectional area of the member smaller, so that the area occupied by the structure is much less than that of the reinforced concrete structure. 2 shenbon steel structure statistics, saving construction area than the reinforced concrete structure as planning the use of the area to add 4.2 line settings, add the floor height. 3 on the basis of building use function request, beam and column section area with small trusses, lattice beam or beam pipe can be directly to fasting, wearing lintel web, can add a ceiling height of 10% storey under the same conditions in the planning. Modern construction of vertical pipe placement, fire sprinkler system, the power of the building automation system wiring is also more complex, easy to fix and cross the structure of the system, convenient maintenance. 4 in the process of cutting in order to ensure that the steel plate does not bend or reduce the deformation of the side of the curve, the use of jump cutting method for cutting.
