A high-rise building measurement control point projection positioning auxiliary device

Abstract

The invention discloses a novel high-rise building measurement controlling point projection positioning auxiliary device. The novel high-rise building measurement controlling point projection positioning auxiliary device comprises a supporting plate and a cover plate, a square placing groove is formed in the middle of the upper surface of the supporting plate, a round clamping groove is formed in the middle of the bottom surface of the placing groove, a transparent scale plate is clamped inside the clamping groove, a round through hole is formed in the middle of the bottom surface of the clamping groove, a slide rod is installed at the bottom surface of the placing groove through a fixed base, a slide block is slidably connected to the side face of the slide rod, and is slidably connected with the placing groove, and an alarm apparatus strengthens the safety in the construction and measurement process; the connecting line of limiting grooves in opposite stand pillars coincide with the diagonal of a mark point, in the construction process, through the cooperation of the transparent scale plate, the device can conduct real-time adjustment and positioning, the control point is permanently stored, in the construction process, the device can be utilized at any time, and the construction measurement precision is guaranteed; through wireless communication of a Bluetooth module, the work efficiency is improved, and the workload of people is reduced.

Description

technical field [0001] The invention relates to the technical field of building measurement auxiliary devices, in particular to a high-rise building measurement control point projection positioning auxiliary device. Background technique [0002] During the construction of high-rise buildings, 4 elevation and plane control points are set on the first floor, and the 4 control points form an elevation and plane control network, so that the control network can measure and control the buildings above the first floor layer by layer. The method is called the internal control method; in the internal control method, the process of transferring the control points of the bottom layer to the upper layer can be described as: when the concrete of the upper floor floor is initially set and can enter the site for construction, the control points of the bottom layer must be projected to the upper layer. Set up a laser plummet at the control point of the first floor. After centering and level...

AI Technical Summary

Problems solved by technology

There are many problems in the process of using this method: the control points projected to the upper floor cannot be stored stably for a long time; after the control points of the lower layer are transferred to the construction layer, the original points cannot be saved because they are located near the center of the projection hole, and can only be saved through Translate to obtain indirect results; after the points projected to the upper floor are translated, the number of measurements is increased, and the measurement error and the probability of measurement errors are increased; after the four control points are projected to the upper floor, through translation, the composition The control network will produce a large cumulative error, and it is not easy to measure and check; it requires staff to go up and down floors continuously, which affects work efficiency
