Short formwork method in basement structure reverse construction
The invention discloses a short formwork method in basement structure reverse construction, and relates to the technical field of reverse construction. In order to solve the problem of poor construction quality, the method specifically comprises the following steps that excavation is conducted at the required depth at the construction position; a concrete cushion is poured; a short formwork is erected, and local downward deep excavation is conducted at the beam column and beam wall joint positions; downward hanging joint treatment is conducted on the short formwork; after the short formwork iserected, steel bar binding and reserving are conducted; concrete is poured; and after the concrete strength meets the requirement, the short formwork is dismounted, and a basement wall column structure is constructed. According to the short formwork method in basement structure reverse construction, by arranging a multi-layer plate, a bowl buckle frame, a first n-shaped frame and other structures, the firmness of the short formwork can be guaranteed; the construction mode of the short formwork is adopted, so that the structure construction precision and quality are effectively guaranteed; andoverexcavation is performed on earthwork during construction, so that the construction operation face is enlarged, a basement beam plate can be constructed together with a stand column and a side wall, and the construction period is shortened.
本发明公开了一种地下室结构逆作法施工中的短支模架方法，涉及逆作法施工技术领域。为了解决施工质量差的问题，具体包括如下步骤：在施工位置开挖所需深度；浇筑混凝土垫层；搭设短支模架，注意在梁柱、梁墙节点部位进行局部向下深挖；对短支模架进行下挂节点处理；短支模架搭设完成后、进行钢筋绑扎和预留；浇筑混凝土；待混凝土强度达到要求后，进行短支模架拆除施工地下室墙柱结构。本发明通过设置多层板、碗扣架、第一几字架等结构，能够保障短支模架的牢固度，采用短支模架的施工方式，有效保证结构施工精度和质量；通过设置施工时对土方进行超挖，扩大了施工作业面，地下室梁板可与立柱、侧墙同时施工，缩短了施工工期。
