Construction method of embedded section steel column base in mass concrete
The invention discloses a construction method of an embedded section steel column base in mass concrete, and belongs to the technical field of building construction. The construction method comprises the following specific steps: (1) binding lower-layer steel bars of a foundation slab and vertical steel bars of a section steel column; (2) positioning and pre-burying the anchor bolts; (3) pouring lower-layer concrete; (4) mounting anchoring steel bars; (5) curing lower-layer concrete; (6) chiseling and cleaning construction joints; (7) section steel column installation and high-strength grouting material secondary grouting; (8) binding upper reinforcing steel bars of the foundation slab and vertical reinforcing steel bars of the section steel column; (9) pouring upper-layer concrete; (10) calendaring the concrete on the surface of the foundation; and (11) foundation maintenance. Concrete is constructed in a layered mode, the lower-layer concrete dissipates heat in advance and is staggered from the hydration heat peak period of the upper-layer concrete, the concrete structure curing time is effectively shortened, and the cracking risk caused by the temperature difference between the inner surface and the outer surface of mass concrete is greatly reduced.
本发明公开了一种大体积混凝土中埋入式型钢柱脚的施工方法属于建筑施工技术领域,具体步骤如下:(一)基础底板下层钢筋及型钢柱竖向钢筋绑扎;(二)地脚锚栓定位预埋;(三)下层混凝土浇筑;(四)安装锚固钢筋;(五)下层混凝土养护;(六)施工缝凿毛并清理;(七)型钢柱安装及高强灌浆料二次灌注;(八)基础底板上层钢筋及型钢柱竖向钢筋绑扎;(九)上层混凝土浇筑;(十)对基础表面混凝土进行压光;(十一)基础养护。本发明将混凝土分层施工,使下层混凝土提前散热,并与上层混凝土水化热峰值期错开,有效减少混凝土结构养护时间,大大降低大体积混凝土里表温差带来的开裂风险。
