Vertical transfer measurement method for high-rise building construction

Abstract

The invention discloses a vertical height transfer measurement method for construction of high-rise buildings. The method comprises the steps that firstly, the first floor control elevation of a proposed building is measured, the control elevation is marked on a tower crane body nearest to the proposed building, and a mark is made; a steel measuring tape is adopted and the mark is used as the standard to perform upward one-time measurement to the top along the tower body, control elevations of all construction layers of the proposed building are marked, and control elevation marks of the construction layers are made; a tape body with the length of 60 cm is cut out, zero graduation of the tape body is aligned to the control elevation marks of the construction layers of the tower crane body,and vertical sticking is performed; during height measurement, control and checking in the construction process of the construction layers, a level gauge is erected in each floor, the corresponding-layer tape body is used as a target, tape body graduations are collimated, back-sight point data can be directly read, and vertical height transfer measurement is achieved. By adopting the method, measurers do not need to perform repeated tower-climbing operation, the measurement efficiency is effectively improved, the operating strength of the measurers is reduced, and the measurement accuracy isimproved.

Description

technical field [0001] The invention relates to an elevation vertical transfer measurement method used in high-rise building construction. Background technique [0002] With the development of infrastructure, the development of the construction industry is very rapid, among which there are more and more construction projects of high-rise buildings; the vertical transmission and inspection and control of high-rise building construction are very frequent and very important. result in irreparable losses. [0003] At present, there are many methods for measuring the vertical elevation of high-rise building construction. The most commonly used method is to first measure the elevation on the bottom tower of the tower crane; The required height of the floor is marked, and then the surveyor climbs to the tower crane with a tower ruler to take a good backsight point, and leads to the construction floor to measure the height or use it for inspection and control. Since the floor unde...

Problems solved by technology

Since the floor under construction needs to be measured and inspected at any time, and there is no stable position to guide the marking, the surveyor needs to climb the tower crane with the tower ruler to read the backsight point data every time.
