Problems solved by technology

However, the disadvantage of this device is that it can only be fixed at the bottom of the top plate of the high-support formwork, and it only monitors the horizontal displacement of the vertical pole at the bottom of the top plate, and cannot monitor the displacement of the vertical pole in other areas. The monitoring range has great limitations. This method does not have the function of accurately locating the position of the displacement pole

Abstract

The invention relates to the technical field of building construction monitoring, in particular to a laser-based high-formwork vertical rod displacement monitoring device and an early warning method.The laser-based high-formwork vertical rod displacement monitoring device comprises a monitoring module, and the monitoring module comprises laser emitters, laser receivers, an analyzer and displacement follow-up parts; the plurality of laser emitters and the plurality of laser receivers are respectively arranged on the side of a high-formwork transverse rod and the side of a high-formwork vertical rod in pairs, laser beams between each pair of laser emitter and laser receiver are vertical or parallel to the ground, and the plurality of displacement follow-up parts are arranged on the high-formwork vertical rod. Any one displacement follow-up part is subjected to displacement change along with the high-formwork vertical rod where the displacement follow-up part is located, the analyzer is connected with the laser transmitter and the laser receiver, and multi-point monitoring of the high-formwork vertical rod and accurate positioning of the position where the displacement of the high-formwork vertical rod exceeds a preset value can be achieved.

Description

technical field [0001] The invention relates to the technical field of building construction monitoring, in particular to a laser-based high-support formwork pole displacement monitoring device and an early warning method. Background technique [0002] With the rapid development of urban modernization, large-span structures and super-high building structures in cities are gradually increasing, and high-formwork systems are more and more widely used in engineering fields. Tall formwork support system is referred to as high-support formwork system for short, which refers to the formwork support system of concrete components with a height of 8m and above, or a formwork support system with a span of 18m and above, which belongs to the more dangerous sub-projects exceeding a certain scale. High-support formwork engineering has the characteristics of complexity, high risk, and sudden accidents. When concrete is poured, the vertical pole of the high-support formwork body is subject...
