Construction method of detachable steel enclosing purlin support
The invention relates to the field of building construction, in particular to a detachable steel enclosing purlin support construction method. The detachable steel enclosing purlin support construction method comprises the steps that an L-shaped support and a lug plate used for supporting the L-shaped support are machined; the mounting position is determined in the steel sheet pile according to the design size, and the lug plate is centrally welded to the convex face of the steel sheet pile at the mounting position; steel sheet piles are driven, and the steel sheet piles with lug plates are constructed at the first construction position and the position separated from the first construction position by the designed distance; earth excavation is conducted on the inner side of the foundation trench in the direction of the steel plate pile, and excavation is stopped until the distance from the pile top of the steel plate pile is 1 m; and the L-shaped supports are firmly installed on the lug plates, the L-shaped supports are leveled through stay wires in the installation process to ensure that the installation elevation is kept consistent, and after the L-shaped supports are installed, the steel enclosing purlins are installed between the L-shaped supports. The construction period of a foundation pit supporting project can be shortened, the lug plate welding quality in a flat field is more reliable than on-site welding quality, the support can be detached and reused, steel is saved, cost is reduced, and benefits are increased.
本发明涉及建筑施工领域，具体为一种可拆卸钢围檩支架施工方法包括：加工L形支架以及用于支撑L形支架的耳板；根据设计尺寸在钢板桩中确定安装位置，在安装位置将耳板居中焊接在钢板桩的凸面上；打钢板桩并在第一根施工位置以及间隔第一根施工位置设计距离处均施工一根带耳板的钢板桩；在基槽内侧沿钢板桩方向进行土方开挖，挖至距离钢板桩桩顶以下1m处停止；将L形支架在耳板上安装牢固，并在安装过程中拉线调平L形支架确保安装标高保持一致，L形支架安装完成后在L形支架之间安装钢围檩。能够缩短基坑支护工程工期，耳板焊接质量在平整场地焊接比在现场焊接质量可靠，支架可拆卸重复利用，节约钢材，降低成本，增加效益。
