Internal control point vertical transmission automatic scribing device and scribing method thereof

Abstract

The invention belongs to the technical field of constructional engineering construction measurement, and particularly relates to an internal control point vertical transmission automatic lineation device and a lineation method thereof.The device comprises a laser plumb instrument and an automatic lineation instrument; the laser plumb instrument is erected on the first building layer of the multi-storey building, and laser beams of the laser plumb instrument sequentially and vertically penetrate through the reserved square holes of all the building layers from bottom to top. The automatic scriber is arranged on an upper building layer near the reserved square hole and used for spraying a cross coordinate positioning line with the center point of the laser beam as the center on the periphery of the reserved square hole. The method promotes intelligent application in the building field. According to the method, the problems of construction measurement errors and low efficiency caused by manually judging the position of the laser beam center point of the laser plumb aligner and drawing the center positioning line around the reserved square hole in the vertical transmission internal control method process of the multi-story building construction are solved.

Description

technical field [0001] The invention belongs to the technical field of construction engineering construction measurement, and in particular relates to an automatic scribing device for vertical transmission of internal control points and a scribing method thereof. Background technique [0002] The appearance of high-rise buildings is an inevitable result of economic development, technological progress, and the shortage of national land resources, and it also brings about the challenge of vertical transmission of high-rise building plane control network. [0003] At present, the internal control method is often used for the axis positioning of high-rise building construction. The internal control method often requires a laser collimator to be set up on the internal control point, and holes are reserved in the upper layer, so that the laser beam is projected vertically upward to the upper layer rake, and then manually determined. Hit the center and draw a centering line around ...

AI Technical Summary

Problems solved by technology

Since the position of the laser point projected by the laser plummet is uncertain, the traditional method is to manually determine the center of the laser beam, move the axis position back and forth, and then manually lead the wires to both sides, resulting in inconvenience and construction measurement errors
