Positioning device and method for cover and excavation top-down concrete filled steel tube center column of subway station
The invention relates to the technical field of concrete construction, in particular to a subway station cover and excavation top-down concrete filled steel tube center column positioning device which comprises positioning mechanisms, the positioning mechanisms are circumferentially spliced to form a disc type design, and each positioning mechanism is composed of a fixed table and a movable table; the movable table is installed on the fixed table in a sliding mode in the radial direction of the center of the disc, a plurality of same movable balls are elastically connected to the arc-shaped face wall of the inner side of the fixed table in a sliding mode, conical blocks are arranged on the arc-shaped face wall of the outer side of the movable table, and the conical blocks are inserted into gaps between every two adjacent movable balls and make elastic contact with the movable balls. According to the positioning device, the problems that the steel pipe column positioning vertical precision is not high enough and the construction cost of steel pipe column installation is high are solved, the self-adaptive perpendicularity correction of the positioning mechanism is matched with the forced perpendicularity correction of the adjusting mechanism, it can be ensured that the steel pipe column is vertically lowered, the construction efficiency is high, and the construction cost is low. And the construction cost can be obviously reduced.
本发明涉及混凝土施工技术领域，尤其涉及一种用于地铁车站盖挖逆作钢管混凝土中柱定位装置，包括定位机构，定位机构周向合拼并形成圆盘式设计，所述定位机构由固定台以及活动台组成，活动台沿该圆盘的中心径向滑动安装在所述固定台上，所述固定台的内侧弧形面壁上滑动弹性连接有若干相同的活动球，所述活动台的外侧弧形面壁上设置有锥块，所述锥块插设在相邻的两个活动球的间隙之间并形成弹性接触，本发明解决了钢管柱定位垂直精度不够高，且钢管柱安装的施工成本较高的问题，本定位装置的提出，通过定位机构的自适应式垂直度校正配合调整机构的强制式垂直度校正，能够确保钢管柱垂直下放，施工效率高，且能够显著降低施工成本。
