Positioning platform and positioning method for foundation pit reverse construction method steel structure column
The invention provides a positioning platform and positioning method for a foundation pit reverse construction method steel structure column, and belong to steel structure column construction devices.The positioning platform comprise an upper operation platform, a lower adjusting platform, a cross beam set, an adjusting device and two hoist hook devices, wherein the two hoist hook devices are correspondingly arranged on the two sides of the lower adjusting platform; the lower adjusting platform is arranged in the shape of a rectangular frame; the cross beam set comprises four cross beams arranged on the four side faces of the lower adjusting platform correspondingly; the adjusting device comprises at least one (preferably two) adjusting bolt arranged on each cross beam, wherein the adjusting bolts are in threaded connection with the cross beams, and the ends of the adjusting bolts abut against the steel structure column; and the hoist hook devices are used for fixing the elevation position of the top of the steel structure column. According to the positioning platform and positioning method for the foundation pit reverse construction method steel structure column, the problems that all technical index requirements are difficult to meet at a time in actual construction and that construction control difficulty is large due to the fact that requirements for a plane center point,a top face elevation, axis distribution, perpendicularity and the like of the structural steel structure column are high in reverse construction can be solved.
本发明提供了一种基坑逆作法钢构柱的定位平台及定位方法，属于钢构柱施工装置，其包括上部作业平台、下部调节平台、横梁组、调节装置，以及两个分别设置于下部调节平台两侧的葫芦挂钩装置，下部调节平台呈矩形框架设置，横梁组包括分别设置下部调节平台的四个侧面的四个横梁，调节装置包括在每个横梁上均设有至少一个(优选的情况是设置为两个)的调节螺栓，调节螺栓与横梁螺纹连接且其端部抵于钢构柱；葫芦挂钩装置用于固定钢构柱顶部的标高位置；解决了逆做法施工对结构钢构柱的平面中心点、顶面标高、轴线分布、垂直度等要求较高，在实际施工中往往出现难以一次性全部满足技术指标要求，施工控制难度较大的问题。
