Cooling and bearing integrated steel column for oversized cast-in-place pile and cooling method
The invention provides a cooling and bearing integrated steel column for a super-large cast-in-place pile and a cooling method, and belongs to the field of building construction. In a large-span steel structure building, a super-large-diameter cast-in-place pile needs to be used as a foundation bearing structure sometimes, and in order to avoid too large hydration heat generated by mass concrete, super-retarding concrete is often adopted in construction to carry out construction of the super-large-diameter cast-in-place pile. However, the construction period is prolonged through the super-retarding concrete, and meanwhile extra risks are brought to construction of embedded components in the super-retarding process. The invention provides a cooling and load-bearing integrated steel column for a super-large cast-in-place pile and a cooling method, the cooling and load-bearing integrated steel column comprises an inner-layer steel column and an outer-layer steel column, the inner-layer steel column is used for bearing, the outer-layer steel column is used for evacuating hydration heat, and the outer-layer steel column improves the combination degree between concrete and the steel column at the same time. According to the integrated steel column and the cooling method, the construction time is effectively shortened, and meanwhile the performance of the cast-in-place pile is enhanced.
本发明提供一种用于超大灌注桩的冷却承重一体钢柱及冷却方法，属于建筑施工领域。在大跨度钢结构建筑中，有时需要采用超大直径灌注桩作为基础承重结构，为避免大体积混凝土产生过大的水化热，施工中常常采用超缓凝混凝土来开展超大直径灌注桩的施工。但超缓凝混凝土延长了工期，同时超缓凝过程也为预埋构件施工带来了额外的风险。本发明提供一种用于超大灌注桩的冷却承重一体钢柱及冷却方法，包括内层钢柱和外层钢柱，内层钢柱用于承重，外层钢柱用于疏散水化热，外层钢柱同时提高了混凝土与钢柱之间的结合程度。本发明的一体钢柱及冷却方法有效缩减了施工时间，同时增强了灌注桩的性能。
