Construction method for back-jacking support of settlement post-cast strip
The invention discloses a construction method for a back-jacking support of a settlement post-cast strip. Belongs to the technical field of constructional engineering. According to the technical scheme, the method comprises the five steps that double-channel steel is welded into a steel stand column for back-jacking, on the premise that the supporting rigidity of the cantilever end of the post-cast strip is met, a large number of steel pipes are saved, space is saved, and follow-up basement masonry construction can be conveniently carried out. When the basement post-cast strip concrete reaches certain strength, the channel steel column for supporting can be detached, the detached channel steel column can be transferred to the next project to be reused, and the material use cost is saved.
本发明公开了一种沉降后浇带回顶支撑的施工方法；属于建筑工程技术领域；其技术要点包括五个步骤，通过采用双槽钢焊接成钢立柱进行回顶，在满足后浇带悬臂端支撑刚度的前提下，大量节省了钢管的使用，节省了空间，以便于后续地下室砌筑施工的开展。本发明通过在地下室后浇带混凝土的达到一定的强度时，用于支撑的槽钢柱能够拆卸，拆除后的槽钢柱可以流转至下个项目进行重复使用，摊销了材料使用成本。
