Loading and measuring device for overturning deformation of timber column

Abstract

The invention relates to loading and measuring device for overturning deformation of a timber column, comprising: a water storage tank, which is filled with liquid and is used for simulating a fluid environment; a bearing platform, which is arranged at the bottom of the water storage tank and used for fixing the timber column to be measured; a steel sleeve, which is used for sleeving the top end of the timber column to be measured; steel strands, tensile springs, calibration screws and nuts, which are used for exerting a force on steel strands to make the timber column to be measured reaches abalance state; loading strands, which are used for pulling the timber column to be measured to be obliquely rotated in the overturning direction; a flat plate, a first dial gauge and a second dial gauge, which are arranged on the steel sleeve and used for measuring an overturning force of the timber column to be measured; pulleys, which are arranged outside the water storage tank and used for guiding the steel strands to meet reducing of an included angle between steel strands and the timber column to be measured. According to the loading and measuring device for overturning deformation of the timber column, a water flowing environment can be simulated, reliability of the measurement is remarkably improved, and meanwhile, readings of the sensor are not affected.

Description

technical field [0001] The invention relates to a wooden column overturning deformation loading measuring device, which belongs to the technical field of sliding mechanisms. Background technique [0002] The overall overturning of columns has always been an inevitable and common problem in wooden structures. It is very important to study the impact of the overturning deformation of real columns on the study of ancient wooden buildings. However, in reality, it is unrealistic to perform pushover loading on an ancient building in service, and it is difficult to reproduce the overturning deformation of columns in real ancient wooden buildings by the traditional oblique loading method in the laboratory. [0003] Therefore, the invention patent with the patent application publication number of CN105319082B discloses a wooden column overturning deformation loading measurement device, which includes a concrete cap and a steel sleeve. Each pull ring is bound and pulled out for cali...

AI Technical Summary

Problems solved by technology

[0004] For some wooden columns set up in rivers and lakes, they will also encounter collisions with other heavy objects such as ships, and they are prone to overturning. However, in the land environment of the above-mentioned technical solution, the simulated overturning deformation loading measurement is because, for example, the flow variables of water bodies are difficult to achieve, so the above-mentioned The reliability of the technical solution is low; if the above technical solution is directly put into the water body, the data cannot be displayed normally due to the limitation of the sensor’s use environment, and a new solution needs to be proposed
