Background
In the current measurement field, due to the reasons of temperature, stress, load and the like in deformation observation, in the monitoring process, from the initial observation by adopting a theodolite and a level gauge to the application of a total station, the current comprehensive application of a super station and a GPS surveying instrument is realized, the development speed is very high, and the measurement efficiency is also very high. However, the labor and the periodicity are long in the using process, the cost is high, the most monitoring and measuring method adopted at present mostly adopts a monitoring system consisting of various sensors and internal hardware and software, and the deformation value can be dynamically observed through software only by installing related devices on a measuring point.
The steel structure deformation monitoring is mainly carried out by adopting the modes for monitoring and measuring, in the construction of the roof pipe truss, observation points and sensors are mainly arranged on the upper chord and the lower chord at intervals after the pipe truss is erected, and when deformation occurs, computer software fluctuates, and technicians can watch the deformation value at any time.
The deformation value is observed in the construction process, and the deformation value is adjusted to avoid influencing point positions of subsequent engineering; and secondly, observing the deformation value after construction and installation, and aiming at observing whether the deformation influence on the deformation value is within the allowable range of the specification through temperature, wind power, partial load and the like. In the first case, the technical characteristics of the method are that the pipe trusses are mostly installed in place one by one, one truss and one line are used for monitoring, so that point position errors are easily accumulated, the single point error is controlled within 2mm, but the accumulated error value is over-limit, and the pipe trusses cannot be accurately positioned when erected to the other side. The positioning is affected slightly, and the installation of the whole structure and the engineering quality thereof are affected heavily.
