Construction technology for large-section frame column in slope area
The invention belongs to the field of building construction, and particularly relates to a construction technology for a large-section frame column in a slope area. The process comprises the following steps of Step 1, measuring the slope size, and calculating the sectional area, the number, the spacing and the reinforcing bar number of concrete brackets according to the slope size; Step 2, performing strength and rigidity calculation on I-shaped steel, Bailey pieces and distribution beams according to the data calculated in the Step 1, checking the deflection of a temporary structure, and adjusting the pre-camber of the support frame according to the deflection, so that the problem of difficulty in construction of a high and large formwork support in a slope area is solved, and the quality and safety problems caused by vertical deformation of the full support frame due to settlement of a high backfill foundation are solved; and the number of support frames is greatly reduced, meanwhile, leap-type support frames are used, support foundations do not need to be treated, concrete does not need to be hardened, the cost for rolling and replacing and filling equipment and the cost for concrete are saved, the safety risk of falling from high altitude is greatly reduced due to reduction of the height of the support frames, and meanwhile the construction period is directly shortened due to the reduced erection of the support frames.
本发明属于建筑施工领域，具体的说是一种用于斜坡区域内大截面框架柱施工工艺，该工艺包括以下步骤；S1：测量斜坡尺寸，根据斜坡尺寸计算混凝土牛腿的截面积、数量、间距和配筋数量；S2：根据S1计算后的数据，对工字钢、贝雷片、分配梁，进行强度、刚度计算，验算临时结构的扰度并按此调整支架的预拱度，解决了斜坡区域高大模板支架施工困难问题，解决了高回填地基沉降引起满堂支架竖向变形引起的质量、安全问题；大量的减少了支架用量，同时采用跨越式支架，支架地基不需要处理，也不需要硬化混凝土，也节约了碾压、换填设备费用和混凝土费用，支架高度的减小也大大的降低了高处坠落的安全风险，同时减少的支架搭设直接节约了工期。
