The invention discloses an adjustable tower crane foundation embedded fixing supporting leg mounting method, and belongs to the technical field of tower crane embedded fixing facilities. The adjustable tower crane foundation embedded fixing supporting leg comprises a vertical support, a horizontal support, an embedded fixing supporting leg body and a limiting clamp. The vertical support and the horizontal support are welded and fixed. According to the invention, the lattice columns and the horizontal supports are fixedly connected into a whole; a structural steel cross beam is vertically and fixedly connected with two adjacent latticed columns, pre-embedded fixed supporting legs are arranged on the structural steel cross beam, and the pre-embedded fixed supporting legs are temporarily fixed to the upper surface of the structural steel cross beam through limiting clamps and used for limiting the relative position relation between the pre-embedded fixed supporting legs. By means of the structural arrangement, the installation mode of an embedded fixed supporting leg with a concrete cushion layer as a vertical support is omitted, and the problem that due to the cushion layer construction quality problem, the installation precision of the embedded fixed supporting leg is insufficient is solved.
本发明公开了一种可调节式塔吊基础预埋固定支腿安装方法,属于塔吊预埋固定设施技术领域。本发明的可调节式塔吊基础预埋固定支腿包括竖向支撑、水平支撑、预埋固定支腿和限位卡,所述的竖向支撑和所述的水平支撑焊接固定。本发明通过根格构柱与水平支撑固接连成整体;通过型钢横梁与两个相邻的格构柱之间垂直固接,通过预埋固定支腿置于所述的型钢横梁上,通过限位卡将所述的预埋固定支腿临时固定于型钢横梁上表面,用于限定所述的预埋固定支腿之间的相对位置关系,本发明通过这种结构设置摆脱了以混凝土垫层为竖向支撑的预埋固定支腿安装方式,解决了由于垫层施工质量问题导致预埋固定支腿安装精度不足的问题。
