空心砌块墙在结构上应用很普遍,有线电视、电话和电源插座几乎全部位于墙上。原来在线盒安装时要先破坏已砌好的砌块,再将线盒沿破坏的孔洞安上,之后用混凝土堵死。这样做的缺点是线盒位置不好控制,施工难度大,工艺复杂,浇筑混凝土会增加结构的自重等。采用下述作法,可巧妙地解 Hollow block walls are common in construction, with cable, telephone and power outlets almost all on the wall. The original online box installation must first destroy the block has been built, and then the box along the hole destroyed, and then blocked with concrete. The disadvantage of doing so is that the position of the wire box is not well controlled, the construction is difficult, the process is complicated, and the pouring of concrete increases the self-respect of the structure. The following approach can be cleverly solved
