Building construction method adopting stepwise implementation of forward construction and reverse construction
A building construction method adopting stepwise implementation of forward construction and reverse construction comprises the following steps: S1, carrying out the reverse construction on vertical support members of a peripheral reverse construction area; S2, using the reverse construction method to carry out construction in the peripheral reverse construction area and manufacture horizontal support members of structural beams and slabs, so that a closed-loop horizontal support system is formed on the periphery of a main building; S3, reserving back pressure earth in the peripheral reverse construction area according to pit deformation requirements, and carrying out excavation on a main building area to reach a base through multistage sloping; and S4, carrying out the forward constructionon a main building area structure, and simultaneously carrying out upward construction on the main building and downward reverse construction on an underground structure of a reserved earth sloping area on the periphery of the main building after beam and slab structures of different floors, which are achieved through the forward construction of the main building, are integrated with beam and slab structures of the different floors, which are achieved through the corresponding peripheral reverse construction. The method provided by the invention has the advantages that the temporary support engineering amount can be greatly reduced, the excavation efficiency can be improved, and the construction progress can be greatly accelerated; and in the peripheral reverse construction stage, a large-space opening in the main building forward construction area is achieved, so that the ventilation and daylighting conditions of underground construction can be remarkably improved.
一种阶梯式边顺边逆的建筑施工方法，包括以下步骤：S1、逆作施工周边逆作区的竖向支承构件；S2、使用逆作法在周边逆作区施工兼做结构梁板的水平支撑构件，在主楼周边形成闭环式水平支撑体系；S3、根据基坑变形要求在周边逆作区预留反压土，并采用多级放坡使主楼区域开挖至基底；S4、主楼区域结构顺作施工，当主楼顺作施工的各层梁板结构与相应周边逆作施工的各层梁板结构形成整体后，在主楼向上施工的同时，向下逆作施工主楼周边预留土放坡区域的地下结构。本发明节省了大量临时支撑工程量，提高出土效率，大大加快施工的进度。在周边逆作施工阶段，主楼顺作区的大空间开口，可以明显地改善地下施工作业的通风和采光条件。
