混凝土楼板凿洞,在建筑安装行业上一般均是以人工手持鎯头、钢凿进行,操作时,劳动强度很高、噪声大、效率低。由于强烈振动冲击,影响楼板结构强度,甚至洞的底部周围会有大面积脱落,如遇上卫生器具多的卫生间,上下水道安装后给土建补洞 Concrete slabs are used for drilling holes. In the construction and installation industry, artificially hand-held boring heads and steel chisels are generally used. During operation, labor intensity is high, noise is large, and efficiency is low. Due to the strong vibration impact, the structural strength of the floor is affected, and there is even a large area around the bottom of the hole. If there is more toilets in the bathroom, the upper and lower channels will be installed to fill the hole after the installation.
