拆除建筑物时的顺序--杨远锋的博客

拆除建筑物时的顺序

[ 2011-7-29 15:40:00 | By: 杨远锋 ]

拆除工程的施工方法，首先要考虑安全，然后考虑经济、节省人力、速度和扰民问题，尽量保存有用建筑材料。
    为了保证安全拆除，必须先了解拆除对象的结构，弄清组成房屋的各部分结构构件的传力关系，才能合理地确定拆除顺序和办法。
    一般说来房屋的结构组成，由屋顶板或楼饭、屋架或梁、砖墙或柱、基础四大部分组成。其传力关系电很明确。
    屋顶板或楼板传力给屋架或梁，屋架或梁传力给砖墙或柱，砖墙或柱传力给基础
    因此，拆除的顺序，原则上就是接受力的主次关系，或者说按传力关系的次序来确定。即先拆最次要的受力构件，然后拆次之受力构件，最后拆主要受力构件。即拆除顺序是：屋顶板-->屋架或梁-->承重砖墙或柱-->基础。如此由上而下，一层一层往下拆就可以。至于不承重的维护结构，如不承重的砖墙、隔墙可以最先拆。但有的砖墙虽不承重，可是起到木柱的支撑作用，这样的情况就不急于拆除，可以待到拆木柱时一起拆。
    除了摸清上部结构的情况之外，还必须弄清基础地基的情况，否则也要出问题，例如某地发生一起拆除一幢临时平房砖墙倒塌砸死人的事故，就是因为不了解该房是建在很浅的土地基上，由于地面水浸泡地基，当屋盖拆除之后，地基土松软，砖墙突然倒塌，造成伤人事故。
