Problems solved by technology

As a result, the J2 level instrument can meet the vertical measurement tolerance of the full-height axis. However, with the increase of the construction height, if a non-rectangular special-shaped construction plane is encountered, it is difficult to ensure the accuracy of the axis measurement of the adjacent layer at a high place. The vertical relative error does not exceed the specified range

Embodiment Construction

[0013] Below, specific implementation manners of the present invention will be described in detail with reference to the accompanying drawings.

[0014] In the laser internal control vertical segment measurement method involved in the present invention, the J-class laser theodolite is mainly used to perform the internal control projection measurement method on the main control line of the building.

[0015] When using the segmented measurement method for vertical deviation measurement, the core issue is how to set the segmented height and how to arrange internal control points. In the following, the selection and measurement steps of these parameters are described in detail.

[0016] 1. Determine the segment height (h 段 )

[0017] According to the requirements of "Reinforced Concrete High-Rise Building Design and Construction Regulations" (JGJ3-91), the maximum vertical deviation of the building's full height (H) structure construction should not exceed H / 1000, and should no...

Abstract

The invention provides a laser internal control vertical section measuring method of a high-rise building, which comprises the following steps: a) dividing the building into a plurality of sections in the total height; b) setting internal control points on a + / -0 plane in the building, then setting the internal control points on the first floorboard layer of each section, and correcting the positions; c) pre-forming delivering holes at corresponding positions of each layer of floor slabs, and taking the internal control points as a basis, testing point positions on the floors of each section vertically through the preformed holes; and d) correcting errors and performing detections and rechecks until the result accords with the error requirement. The measuring method has precise test result, and can obviously improve the verticality of the total height of the main body of the building, prolong the service life of the building, and simultaneously save leveling materials for the external wall.

Description

technical field [0001] The invention relates to a laser internal control vertical section measurement method for a high-rise building, in particular to a method for using a laser to perform internal control vertical section measurement in a high-rise building. Background technique [0002] In the construction of high-rise buildings, due to the limitation of the surrounding environmental conditions of the site, it is becoming more and more difficult to measure the axis vertically with the external control method, while the laser internal control vertical measurement technology has the characteristics of fast speed and high precision. It is widely used in the vertical measurement of buildings. [0003] When using the laser projection point internal control method for measurement, the more traditional and common method is to pre-embed a steel plate on a certain layer (in most cases, the first layer) during the construction process to set the projection point, and then always us...
