construction steel structure engineering controls focus

Guangzhou Steel tells you: construction steel structure engineering controls focus

1, steel structure construction in high strength bolt connection. High-strength bolts connected is an important factor affecting the quality of construction quality of steel, high-strength bolts product manual torque coefficient is the calibration value at room temperature, the factors affecting the torque coefficient of many, such as: ambient temperature, the final twist moment, tightening speed, especially on the maximum ambient temperature, under normal circumstances, the product manual torque coefficient is the calibration value at room temperature, in negative temperature should be re-calibrated, otherwise, upon the instructions given by the value of manipulation, it is possible to produce the bolt tensile stress insufficient, reducing the safety of construction, or cause bolt tightening, affect the safety of the structure.

2, warm winter negatively welding. Winter negative temperature welding and room temperature are very different, in the welding of welder training to master the negative temperature welding under the law, and specification requirements for welding baked and dried before use, to ensure the welding quality, ensure construction Safety.

3, the development of winter construction safety measures. Construction in winter low temperatures, factors that lead to accidents more, before construction to develop appropriate measures for winter construction safety, equipped with the necessary security products, construction personnel safety education, especially high-altitude operations and special types of education, and to strengthen the on-site construction management work to ensure the safety of construction projects.
