Recently, after the comprehensive assessment of Liaoning Construction Industry Association and Shenyang Jianzhu University, the "dark nail horizontal laying technology" completed by the project team of BMW Brilliance of China Construction Second Bureau North Company was identified as reaching the international leading level.
Workers laying wall panels
It is reported that in the construction of the BMW Group's world's largest assembly workshop factory, in view of how to improve the thermal insulation and wind resistance of the super industrial plant in the cold area, the project team innovated the use of hidden nail horizontal laying technology, through the wall panel horizontal laying, combined with the special design of the dark nail structure and the shape of the upper and lower enterprise mouths, to avoid rust caused by the exposure of self-tapping screws. At the same time, the use of thermal insulation sponges and sealing strips reduces the generation of cold bridges and improves the waterproofness and thermal insulation effect of the wall. More than 16,000 wall panels are like a "cotton coat", allowing the plant to withstand 10 winds and maintain an internal temperature of 25 ° C in winter.
The scientific and technological achievements have effectively solved the problem of air tightness of the wall composite panel system of super industrial plants in severe cold areas, improved the quality of engineering construction, had good economic and social benefits, actively promoted the progress of automobile plant research technology in severe cold areas, and had important reference and guiding significance for similar construction technologies.
