Research on Construction Technology for Prefabricated Stone Curtain Wall Base Keel

Abstract

For outer wall maintenance, the stone curtain walls are arranged on the edge of the construction accesses. There are many cross operations and high risks of construction safety. The disadvantages includes limited construction period, site constraints, local weather conditions, pedestrians and trucks. In case of construction with traditional methods, it will be necessary to close the on-site accesses most of the time, which hinders mobilization of the materials and cross-operation of other organizations and makes construction impossible in rainy days. In addition, there is high safety risk, and the work efficiency and construction period will be greatly affected. In order to ensure safety and the construction period, prefabricated base keels were planned for construction based on the site investigation and analysis. These keels were transported and installed intensively in different periods of time, so that the safety factor was significantly increased and the work efficiency was met. After prefabricated base keels were used for project construction, the stone base keels were completed successfully as scheduled. In terms of the selection of measures, construction progress, and quality, this project has won unanimous praise from the Owner and all parties. After the acceptance of the project, the stone base keels were determined as an excellent subdivisional work.
