基础预留螺栓孔或较深的预留洞 ,多采用孔位固定芯模的方法。木模板损坏的碎块也不易清理 ,既浪费资金又影响工期。这里介绍一种利用泡沫塑料板和固定芯模相结合的施工方法。制作固定芯模时 ,截面尺寸要比设计预留孔截面小２０ｍｍ ,四个侧面用２０ｍｍ厚泡沫塑料板胶粘在固定?
Based on the reserved bolt hole or deeper reserved hole, multi-hole hole fixed core method. Damaged wooden form is not easy to clean the pieces, not only a waste of funds and the duration of the project. Here is a construction method using a combination of a foam board and a fixed mandrel. When making a fixed mandrel, the cross-sectional dimension is 20mm smaller than the reserved hole and the four sides are fixed with a 20mm thick foam board.
