A Fixing Device Used for Integral Deformation Detection of Ancient Building Timber Structures

Abstract

The invention provides a fixing device for detecting the global deformation of an ancient timber structure. During the global deformation detection on the ancient timber structure, a transverse-distance expansion link and a longitudinal-height expansion link are adopted for positioning in two directions to determine the planimetric position of deformation detection according to the self-features and the height of the timber structure, and then a transverse-distance expansion link support is employed to provide external supporting force for the transverse-distance expansion link. A deformation detector carrying device is employed to fix a detector and carry out data acquisition, and therefore, the deformation detection requirements of different heights, view angles and the like of ancient buildings are met and the process of setting up the deformation detection fixing device is shortened; meanwhile, the efficiency of the global deformation detection of the ancient structure is further improved and the working strength of the personnel is reduced.

technical field [0001] The invention relates to a fixing device for detecting overall deformation of an ancient building wooden structure. The invention belongs to the technical field of overall deformation detection of wooden structures and protection of ancient buildings. Background technique [0002] At present, the common detection methods for the overall deformation of ancient wooden structures use deformation detectors to detect them. For example, using the principle of laser ranging and using a three-dimensional laser scanner, the three-dimensional coordinates of a large number of dense points on the surface of ancient wooden structures and The records of texture and other information can quickly collect the spatial point information of the wooden structure of ancient buildings, and provide effective data support for evaluating the overall deformation of wooden structures of ancient buildings.

AI Technical Summary

Problems solved by technology

[0003] At present, due to the differences in the equipment of deformation detectors, the deformation detection and fixing devices are often fixed with ordinary surveying and mapping, photography and other brackets. When the wooden structure of ancient buildings needs to be fixed on high-position wooden components such as beam squares, bucket arches, and seam panels, etc. For deformation detection or local detailed data collection of a wooden component at a high place, ordinary surveying and mapping brackets cannot meet its functions, and the traditional method of temporary lap scaffolding or plate splicing can only be relied on to meet the needs of ancient building wooden component deformation detection.

This traditional method increases the labor intensity of personnel and increases the cost of deformation detection. At the same time, the deformation detector is placed at a high altitude without fixing for data collection, which not only affects the accuracy of the data, but also has certain potential safety hazards.

[0004] Facing the current demand for different heights of the overall deformation detection of ancient buildings and the lack of fixation of the deformation detector, this invention proposes a fixing device for the overall deformation detection of ancient wooden structures, mainly using telescopic rods in both vertical and horizontal directions The carrying device of the parts and deformation detector replaces the traditional fixing device or data acquisition method, which is easy to operate and use on site, not only accurately collects the data collected by deformation detection, but also improves the detection efficiency and the safety of the deformation detector.
