Steel structure building construction technology is simple, with good stability and seismic resistance, has won the approval of the masses.In the era of advocating green building, whether in rural areas or cities, building houses with steel structure seems to be an inevitable trend.Steel structure house is composed of various components. What problems should be paid attention to when building steel structure house?In order to ensure the quality and stability of steel structure buildings.Three dimensional steel structure small make up with you to discuss some related knowledge of building steel structure house.

     1、 It is necessary to make clear the original structure layout, select the reasonable connection position and connection form between the steel structure and the original structure, so as to avoid the damage of the original structure by the steel structure load. 

     2、 The layout of primary and secondary steel beams of steel structure should be combined with the building, decoration and installation design of attic to avoid or reduce the secondary damage to the steel structure in the process of decoration and installation.

     3、 It is not recommended to use hollow steel such as square steel and pipe steel, because it is difficult to brush antirust paint inside the steel. Due to the change of cold and hot in the north, the steel condensate rust will pollute the ceiling and wall, and seriously endanger the safety. 

     4、 Steel structure layout stress should be clear, force transmission route should be clear and concise.Due to the obvious stress and vibration of the steel structure itself, it is necessary to analyze and calculate accurately, strictly control the structural deformation and vibration frequency, ensure the visual beauty of the structure, eliminate the resonance between the structure and human activities, avoid the shear fatigue damage of the structure caused by resonance phenomenon, and ensure the comfort in the use process.

     5、 Steel (channel steel, I-beam) purchase, generally we have 10, 12, 14, 16 specifications to choose.No matter what specification is selected, it is recommended to use “national standard” steel, because its steel quality and specifications are better than “non-standard steel”. Non standard steel has high hardness, brittle steel, poor ductility, and is not easy to cut and drill holes. 

     6、 Before fixing the channel steel, one side of the channel steel against the wall shall be painted with antirust paint, but other parts shall be painted after welding, otherwise the welding work will be affected.

     7、 For steel structure construction, pay attention that I-beam and channel steel must be of the same specification, and “full welding” must be selected. The main keel should be whole steel, and intermediate welding is strictly prohibited.

      There are many objective factors affecting the steel structure in nature, so it is necessary to select the type of steel structure and make corresponding protection treatment according to the geographical environment and climate when building the steel structure.In the process of steel structure installation and production, every link and every detail is linked. Therefore, the construction technicians should be patient enough to ensure the quality of each link, so that the employer can live in a safe and reliable home.
