A device for measuring the equivalent wall thickness of scaffolding steel pipes and its measuring method

Abstract

The invention discloses a device for measuring the equivalent wall thickness of a scaffold steel pipe and a measuring method thereof. A loading detection component is fixedly mounted on a simple support steel frame, concentrated force F is directly exerted on the middle of the scaffold steel pipe to be measured, according to the measured concentrated force and deflection of the steel pipe, the equivalent wall thickness (please see the specifications on the formula) of the steel pipe is calculated on the basis of the mechanics principle, and the equivalent wall thickness of the scaffold steel pipe is accurately calculated according to the action force exerted on the scaffold steel pipe to be measured, the strength of the applied force, and the deformation degree of the scaffold steel pipe to be measured. The method and device are easy to operate, the strength of the applied force and deformation data of the scaffold steel pipe are automatically monitored, errors caused by manual reading are avoided, the measured result is accurate and reliable, and the method and device have the advantages of being low in cost, easy to operate, accurate in measuring data, high in efficiency and the like.

Description

technical field [0001] The invention relates to the field of building material measurement, in particular to a device for measuring the equivalent wall thickness of scaffolding steel pipes and a measurement method thereof. Background technique [0002] At present, there are many problems in the use of steel pipe scaffolding. For example, because the steel pipe is repeatedly used, it is exposed to wind and rain for a long time, and it is easy to rust, which causes the thickness of the steel pipe to change, which affects the construction safety. Therefore, it is necessary to Detect changes in the thickness of steel pipe scaffolding, and take necessary measures in time. At present, the thickness of steel pipes is mainly measured manually by contact calipers. This method is cumbersome, time-consuming and labor-intensive, and relies on human eye detection. Long-term visual inspection can easily cause human eye fatigue, resulting in large measurement errors and low accuracy. In a...
