Problems solved by technology

[0004] The purpose of the present invention is to overcome that the measuring range of the displacement laser measurement measuring device existing in the prior art does not meet the horizontal displacement detection of the building structure, especially cannot meet the larger level caused by wind load and uneven settlement in the super high-rise building structure. To solve the problem of displacement measurement, provide a device to improve the range and accuracy of laser measurement of horizontal displacement of building structures

Abstract

The invention relates to the technical field of horizontal displacement measurement of building structures, in particular to a novel horizontal displacement laser measuring device for building structures. According to the novel horizontal displacement laser measuring device, a moving mechanism is arranged, the moving mechanism comprises a guide rail and a driving mechanism, the horizontal displacement laser measuring device is arranged on the guide rail, the driving mechanism is connected with the horizontal displacement laser measuring device, the driving mechanism can drive the horizontal displacement laser measuring device to move along the guide rail on the guide rail, the driving mechanism is further connected with a displacement controller, and the displacement controller controls amovement distance of the horizontal displacement laser measuring device in the horizontal direction; and by replacing the traditional horizontal displacement laser measuring device with the novel horizontal displacement laser measuring device, the horizontal measuring range of the horizontal displacement measuring device is increased, and the problem of the large horizontal displacement detectingrange of high-rise building structures is solved. According to the corresponding use method of the novel horizontal displacement laser measuring device, the precision of displacement measurement laserpixel point judgment and pixel coordinate precision are improved through adding horizontal pixel value correction and light intensity value correction, and the problem of low precision of the conventional measurement is solved.

Description

technical field [0001] The invention relates to the technical field of horizontal displacement measurement of building structures, in particular to a novel horizontal displacement laser measuring device for building structures and a novel horizontal displacement laser measuring method for building structures. Background technique [0002] During the construction and operation of high-rise building structures, towering structures such as water towers and iron towers, bridges, dams and other buildings or structures, their horizontal displacement needs to be measured and monitored to monitor their safety and health status. The above-mentioned structure has a large height and can produce a large horizontal displacement of tens of centimeters. At present, it is mainly measured by manual methods, which is time-consuming and costly, and the measurement accuracy is low, making it more difficult to realize automatic measurement and monitoring. For this reason, the horizontal displace...
