1, design specification to perfect our steel structure high-rise residential development in 2001, the first encounter the problem on the design. When the steel structure housing technical guidelines for the total, the steel frame - reinforced concrete core tube residential technical guidelines "is still in preparation, the selection of the specification is different, in the design process we convened expert discussion meeting for many times. Although experts gave the nod, expert discussion meeting and cannot be used as a technical guideline. When the plan approval and problems met by what standard trial. In this way, a small boat ran aground for many times, after several push and pull not formally set sail. So we feel for developing steel structure housing and its specification must come first, and the specification must adapt to the development of all kinds of steel structure residence structure system, to promote the steel structure housing system is quite difficult.
2, select the appropriate fire prevention measures the characteristics of steel at high temperature strength will decline, decided the steel structure housing fire problem must be considered, because it is a residential buildings, the building after put into use, how to protect good fireproof material is also a big problem, so as the steel structure housing, need to find a proper and reasonable fire prevention measures, to ensure the safety of residents in whole. We tried a variety of fire prevention in the two projects treatment scheme, such as fire retardant coating with fire prevention board, with C20 concrete, with, with ALC board, etc., and according to the different situations, different requirements, choose different construction schemes, to make the reasonable and feasible fire prevention measures for a large amount of exploration.
3, exterior wall enclosure still need to study the structure of the steel structure housing system in steel is given priority to, and used for the outer walls of the steel structure housing material requirements is qualitative light, waterproof, anti-cracking, easy construction, moderate price, so choose configuration retaining wall material, related to the design of the structure, related to the guarantee of product quality, related to responsible for the user. Choose what kind of material is used for steel structure residential building is good - this is related to the popularization and application of the steel structure housing vigorously big problem. In line with the aim of steel bone tenderness, we carried out research, resolved: be sure to do a good job building insulation and prevent leakage. With what kind of wall material, block? Hangs Taiwan? Which products? Technical personnel available for waterproof, thermal insulation of external wall lightweight materials are compared, and repeatedly even in site for different intensity of spray test for 24 hours, to the material supply of supporting units and construction units to provide solutions discussed repeatedly, and also pay more attention on the processing, etc., for doors and Windows and walls attaches not ooze water requirement on craft and material. Practice also tells us, in this respect our country's research and material supply is relatively lagging, it remains to be further developing.
