Full reverse construction method for core tube of high-rise building
A high-rise building core tube full reverse construction method belongs to the technical field of building construction and comprises the following steps: step 1, forming upright piles, inserting steel columns into pile foundations in a one-column one-pile manner, and arranging vertical supporting steel columns with corresponding bearing capacity and the pile foundations under a shear wall; secondly, excavation is conducted to the elevation of a floor plate of the negative first floor, the negative first floor serves as an interface, construction of beam plates of the negative first floor is conducted, and construction of a horizontal structure is completed; thirdly, basement construction is conducted to a bottom plate through a reverse construction method, overground main body structure construction of the building is conducted synchronously, and all layers of shear walls above the first layer are completed in sequence; fourthly, after the overground main body structure of the building is constructed, bottom plate pouring is carried out, and after pouring is completed, an underground shear wall is constructed in sequence; and fifthly, the vertical supporting steel column and the redundant part of the temporary joist are dismantled. The problem that the shear wall cannot be reversely constructed can be solved, stress conversion of the temporary steel column and the shear wall is achieved, the method is particularly suitable for rock stratum construction, and the construction period can be greatly shortened.
一种高层建筑核心筒全逆作施工方法，属于建筑施工技术领域，包括以下步骤：第一步，形成立柱桩，采用一柱一桩形式将钢柱插入桩基内，在剪力墙下设置相应承载能力的竖向支承钢柱与桩基；第二步，开挖至负一层楼层板标高，以负一层为分界面，进行负一层梁板施工，完成水平结构施工；第三步，采用逆作法进行地下室施工至底板，同步进行建筑物地上主体结构施工，第一层以上各层剪力墙顺做完成；第四步，待建筑物地上主体结构施工完毕后，进行底板浇筑，浇筑完成后，再顺做地下剪力墙；第五步，拆除竖向支承钢柱和临时托梁多余部分。本发明能解决剪力墙无法逆作的难题，实现临时钢柱与剪力墙的受力转换，特别适应于岩质地层施工，可大大节约工期。
