Recently, the technological achievement "wall window structure" organized and compiled by Nanjing Construction Engineering Group Co., Ltd. was granted a utility model patent certificate by the National Intellectual Property Administration.

      The basic content of this patent originates from the "construction method of plastering before installing plastic-steel windows" organized and compiled by the group's Zijin Science and Innovation General Contracting Company. The "wall window structure" utility model patent changes the traditional installation and construction process sequence of plastic-steel windows. On the premise of ensuring good air tightness and water tightness of plastic-steel windows, it effectively eliminates the common quality problem of leakage at window edges, and at the same time avoids the previous cross-construction between plastic-steel window installation and wall plastering operations, which is very conducive to finished product protection and has the notable characteristics of low cost and good quality.

       After this patent is authorized, it will provide certain technical support for improving the quality of construction products, reducing costs, and saving energy and increasing efficiency. At present, Zijin Science and Innovation General Contracting Company is strengthening internal training and actively promoting the application of this utility model patent, so that the achievements of technological progress can bring better quality and efficiency benefits to the enterprise.
