Construction method of underground frame foundation connecting structure
The invention discloses a construction method of an underground frame foundation connecting structure. The construction method comprises the following steps that a groove body side line is determined, and a first construction section reinforcement cage, a first construction section connector, a later construction section reinforcement cage and a later construction section connector are prefabricated; a first construction section groove section is excavated according to the side boundary of the groove body, the first construction section reinforcement cage and the first construction section connector are lowered, and concrete is poured into the first construction section groove section to form a first frame foundation; a later construction section groove section is excavated according to the side boundary of the groove body, the later construction section connector and the later construction section reinforcement cage are lowered, the later construction section connector and the first construction section connector are oppositely placed to form a connector box, and then concrete is poured into the later construction section groove section to form a second frame foundation; and the first frame foundation and the second frame foundation are connected in the connector box, and then concrete is poured into the connector box to complete construction. According to the construction method, the bending moment load can be effectively transmitted, and the problem that the continuous underground frame foundation is weak in bending resistance and shearing resistance at the construction joint is solved.
本发明公布了一种地下框架基础连接结构的施工方法，包括以下步骤：确定槽体边线，预制先施工段钢筋笼、先施工段接头、后施工段钢筋笼和后施工段接头；根据槽体边线开挖出先施工段槽段，下放先施工段钢筋笼及先施工段接头，向先施工段槽段浇筑混凝土形成第一框架基础；根据槽体边线开挖出后施工段槽段，下放后施工段接头及后施工段钢筋笼，并使后施工段接头与先施工段接头相对放置形成接头箱，然后向后施工段槽段浇筑混凝土形成第二框架基础；于接头箱内将第一框架基础和第二框架基础进行连接，然后向接头箱内浇筑混凝土完成施工。本发明能够有效传递弯矩荷载，解决了连续地下框架基础在施工接头处抗弯、抗剪能力弱的问题。
