High -strength bolt connection is one of the most connected forms in the steel structure engineering. The quality of the high -strength bolt quality directly affects the stability and safety of the entire steel structure.
(2) The effect of cold processing of cold processing on steel is cold -processed steel refers to cold rolling, cold pull -out and cold extrusion. At present, it is more common to use rust -proof paint.The more industrial environmental protection requirements in the world
It has to be said that although urban life is convenient, it is still troublesome in some aspects. With the increase of urban population and frequent congestion in the peak period, light steel structure housing began to enter people’s vision, meeting the people’s pursuit of quiet villa life.. Therefore, the cost of light steel structure
Building Materials Application Steel Structural Fire Preventing Coating Application of Huangyu 10,000 Lin 2 (1. Department of Civil Engineering, Jiangxi Science and Technology Normal University, Nanchang 330013; 2. Nanchang City Architectural Design Research Institute
Wu Yongqing Wang Li structure, so the component expansion generates additional stress. The test results show that at about 0*C700*C (steel temperature), the thermal expansion of the component increases with the increase in temperature. During the 800C900C period, the component is extended in the original extension
Customs: Steel frame structure; accuracy analysis; calculation method; 5: target 1 lead G with the development of urban construction, more and more buildings of steel frame structures, measurement in the detection and acceptance process of steel structure engineering is measurement is the measurement and acceptance process.A stronger professional and very heavy
