Method and device for simply testing the strength of building steel

Abstract

The invention discloses a method and a device for simply and conveniently detecting strength of building steel. The method comprises steps as follows: a standard sample with qualified known strength is subjected to critical index detection on the detection device provided by the invention, and standard deflection and standard load are determined; a to-be-detected sample is detected with the same method according to the standard load, and whether the strength of the to-be-detected sample is qualified can be rapidly judged through observation of the deformation condition of the to-be-detected sample and a relationship of to-be-detected deflection and the standard deflection. According to the mode, conclusion determination can be realized without quantization of a detection result, the detection efficiency and the constriction efficiency of the steel in the site are greatly improved, and the detection method is fast, effective, economic and applicable.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a method for simply detecting the strength of building steel. Background technique [0002] In construction sites and other places, a large amount of steel materials such as various steel bars, steel plates and section steels are usually used, and these steel materials usually have to be tested for their mechanical properties before they can be used, but because there are no ready-made experimental testing equipment on the construction site , so the on-site steel to be inspected cannot be detected in time, resulting in a delay in the construction period. [0003] The strength of construction steel refers to the ability of the material to resist fracture under the action of external force. The strength of construction steel is an important index that must be measured in use. Contents of the invention [0004] The purpose of the present invention is to provide a method for eas...
