Problems solved by technology
The reference line, reference positioning pile, and auxiliary line of the traditional setting-out method increase and lengthen the workload. The reference line and auxiliary line must be removed after the setting-out is completed, so as not to confuse the gray line system of the pillar foundation pit for forming and positioning, and the workload repetitive, heavy, complex

The invention relates to a tool and a using method of the tool, in particular to a ruler-free locating foundation pit tool and a using method of the ruler-free locating foundation pit tool. According to the tool, a rectangular frame is made of steel bars, central lines and various side line marks are arranged on all sides of the rectangular frame, and a nut is fixed to the junction of the diagonal lines of the rectangular frame. According to the technical scheme, the ruler-free locating foundation pit tool and the using method have the advantages that auxiliary work for traditional locating paying off can be reduced, necessary process work for the traditional locating paying off is removed, the complex technical work of the traditional locating paying off is simplified to be the simple instrumentalization operation, the paying off ruler-free operation is achieved, construction efficiency is improved, the construction process is improved, accuracy of construction quality is improved, labor force investment is reduced, repeated and mechanical labor of engineering technicians is removed, paying off accuracy is effectively improved, and therefore final construction work product quality is effectively guaranteed.
Description
technical field [0001] The invention relates to a tool and its use method, in particular to a rulerless foundation pit positioning tool and its use method. Background technique [0002] In the construction process of construction projects, positioning and setting out is an essential process of construction and the primary work of construction. The quality of positioning and setting-out directly affects the quality and even the function of the construction project. Ordinary frame structure system, the bays and depths are not too large, and it can even be excavated by connecting dense foundation pit earthwork excavations to make trenches. There are more reference objects and more control points, which is convenient for layout. It is easy to control the accuracy of positioning and setting out. [0003] The single-story industrial plant is different, with a span ranging from tens of meters to tens of meters, and a length ranging from hundreds of meters to hundreds of meters. ...
