| 摘 要： | 在超长钢筋混凝土结构施工中,为防止混凝土受温度应力和干缩应力而引起开裂,通常采用设置后浇带的方法加以处理.一般每30～40 m设一道后浇带,40～50 d后再浇筑膨胀混凝土.这种常规的后浇带施工,工序复杂,施工时间长,质量不易保证.东莞商业中心三期B区H-6项目工程施工中,结合超长混凝土结构的具体特点,采用超长混凝土结...

| Abstract: | During the process of super-long reinforced concrete structure construction,the method of setting post-cast strip is often used to prevent stress cracking caused by thermal stress and shrinkage of concrete.Generally,a post-cast strip should be set every 30-40 meters,and then expansive concrete be poured after 40 -50 days.The disadvantages of the conventional post-cast strip construction are that the process is complex,and construction period is very long.What is more,it is difficult to guarantee the quality... |
