A method of measuring, positioning and setting out for high-rise building construction

Abstract

The invention discloses a method for measuring, positioning and laying out lines in high-rise building construction. By piloting the two original measurement control points to the appropriate positions of the existing high-rise buildings around the proposed building, to ensure that the elevation of the pilot point is greater than or equal to the plane elevation of the proposed building, marked as the first pilot point and the second pilot point; At the same time, according to the visual observation, the temporary erection point of the instrument should be erected on the connection line formed by the two pilot points as far as possible on the proposed building plane. Observe the actual alignment point of the reticle in the mirror, visually observe the distance between each point, and calculate the vertical distance between the temporary erection point and the connecting line formed by the two pilot points. By moving the instrument, ensure that the instrument is finally located at the two pilot points. On the connecting line, the two pilot points are then piloted to the floor plane of the proposed building construction, so as to realize the set-out work of the control line. The invention has the characteristics of simple operation, high measurement efficiency and accurate measurement results.

Description

technical field [0001] The invention relates to a method for measuring, positioning and laying out lines for high-rise building construction, belonging to the technical field of building construction Background technique [0002] Among the measurement and positioning methods in the field of construction, the commonly used methods are internal control method and external control method. The internal control method is currently used in high-rise buildings. It is necessary to reserve several transmission holes on each floor to project the control points to other floors. The reservation and later filling of the transmission holes is relatively troublesome. With the external control method, as the floor rises, it may be necessary to pilot and measure the control piles many times, which is easy to cause errors. Moreover, the project construction site is limited, and it is very difficult to guide the measurement and control piles to the distant flat ground; on the other hand, the s...

AI Technical Summary

Problems solved by technology

With the rise of the floor, the external control method may need to measure the control piles many times, which is easy to cause errors, and the construction site of the project is limited, so it is quite difficult to lead the control piles to the distant flat ground; on the other hand, the surveyors need to carry The instrument goes to each control pile for measurement. The higher the floor and the farther the control pile is, the more time wasted by the surveyor on the journey, resulting in low measurement efficiency
