Super-long loop equipment foundation construction joint setting method

CAO XINWEN

The invention relates to the field of building construction, and discloses a super-long loop equipment foundation construction joint setting method. The super-long loop equipment foundation construction joint setting method comprises the following steps that (1), after a construction joint is reserved at the position of 30-40 m, a construction joint is reserved at the interval of 2 m, a construction joint is reserved at the interval of 30-40 m, and the reserved positions of the construction joints are sequentially set according to the rule; (2), a reinforcing band is arranged within the range of 2 m between the construction joints; and (3), a foundation bottom plate, wallboards, a top plate and a reinforcing band of the super-long loop equipment are poured in sequence according to the construction direction. According to the super-long loop equipment foundation construction joint setting method, the construction joints are reasonably arranged, the reinforcing band is additionally arranged within the range of 2 m between the construction joints, and the concrete adopts the shrinkage-compensating concrete with the specific restrained expansion rate, so that harmful cracks can be reduced; and a post-cast strip is not arranged, only an expansion reinforcing band is arranged, the reinforcing band and construction parts (the bottom plate, the wallboards and the top plate) are continuously constructed, and the construction period is shortened.

本发明涉及建筑施工领域，公开了一种超长活套设备基础施工缝设置方法，包括以下步骤：1)30m～40m留置一处施工缝后，再间隔2m留置一处施工缝，再间隔30m～40m留置一处施工缝，按照这个规律依次设置好施工缝的留置位置；2)在所述施工缝间2m范围内设置一道加强带；3)超长活套设备基础底板、墙板、顶板及加强带，按施工方向顺次进行浇筑。本发明通过合理设置施工缝，在施工缝间2m范围内增加一道“加强带”，且混凝土采用特定限制膨胀率的补偿收缩混凝土，能够减小有害裂缝产生；未设置后浇带，仅设置膨胀加强带，此加强带与施工部位(底板、墙板、顶板)连续施工，节约工期。
