Construction method for closing post-cast strip of outer wall in advance
The construction method for sealing the post-cast strip of the outer wall in advance comprises the following steps that S1, a customized formwork is manufactured, specifically, the formwork is customized according to the height of the post-cast strip; s2, concrete blocks are manufactured, wherein fine aggregate concrete precast blocks are poured; and S3, the concrete blocks are hoisted and spliced, specifically, the prefabricated blocks are hoisted to the designated position in the mode that hoisting holes are reserved and a tower crane is used for hoisting, and then the prefabricated blocks are spliced in an up-down concave-convex joint mode, so that the problem of grout leakage of a splicing seam of the two concrete blocks is solved. The concrete precast blocks are formed through formwork design and pouring, the outer wall post-cast strip is sealed in advance, the waterproof construction quality and the progress of backfill soil construction in advance are met, the cost of sealing in advance is effectively reduced, meanwhile, hoisting holes are reserved in the precast blocks, the tower crane hoisting mode is utilized, and the problems that the self weight of the concrete blocks is large, and the construction cost is low are effectively solved. And meanwhile, the problem of grout leakage of splicing seams of the prefabricated blocks is solved by adopting up-down concave-convex connection, and the prefabricated block is convenient to mount and splice and easy to construct.
本发明公开了一种外墙后浇带提前封闭的施工方法，包括以下步骤：S1、制作定制模板：根据后浇带高度，进行模板定制；S2、制作混凝土块：浇筑细石混凝土预制块；S3、混凝土块吊装、拼接：通过预留吊装孔的使用塔吊吊装的方式，将预制块吊运至指定位置，再将上下凹凸接茬拼接，解决了两块混凝土拼缝漏浆的问题。本发明通过模板设计浇筑形成混凝土预制块，对外墙后浇带进行提前封闭，既满足防水施工质量、回填土提前施工的进度，又有效地降低提前封闭成本,同时预制块上预留吊装孔，利用塔吊吊装的方式，有效解决了混凝土块自重大，运输困难的问题，同时采用上下凹凸接茬解决了预制块拼缝漏浆的问题，安装拼接方便，易于施工。
