Problems solved by technology

[0004] The purpose of the present invention is to provide a metal compression performance detection method and detection device thereof, to solve the problem that most of the existing steel bar detection mentioned in the above background technology is detected at room temperature. my country has a vast territory and different climates. Steel bars will show different compressive properties in different temperature regions. The data of the compressive performance test of steel bars in a certain place may not be applicable in other temperature areas, and most of the existing steel bar tests use a single set of data statistics when testing , it is easy to produce large errors, and the existing steel bar detection device is not convenient to fix and quickly disassemble the steel bar to be tested, and it is not convenient to continue continuous detection

Abstract

The invention discloses a metal compression resistance detection method and device, wherein the method comprises the following steps: S1, sampling: taking a plurality of groups of steel bars with thesame diameter, checking whether the surfaces of the steel bars are complete or not, and cutting the steel bars by 60-80 cm in length; S2, maintenance: removing the dust and impurities on the surface of the reinforcing steel bar, and cleaning off the rust stains on the surface of the reinforcing steel bar, and smearing certain lubricating oil for maintenance for 24 h; and S3, grouping: grouping themaintained reinforcing steel bars are grouped into six groups by three pieces in each group. By means of a temperature control box, a steel bar to be measured can be placed in the temperature controlbox; different temperatures are set; the steel bars are subjected to compression resistance detection, the compression resistance of the steel bars is detected at different temperatures, the detection range is wide, the compression resistance of the steel bars can be better judged, the multiple steel bars are detected at the same temperature, then the average value of the multiple steel bars is calculated, the average pressure value of the steel bars at a certain temperature is obtained, and the detection effect is good.

Description

technical field [0001] The invention relates to the technical field related to the detection of metal physical properties, in particular to a method for detecting the compressive performance of metals and a detection device thereof. Background technique [0002] Building materials are a general term for materials used in civil engineering and construction engineering. They can be divided into structural materials, decorative materials and some special materials. Among them, the requirements for structural materials are extremely strict, because structural materials are directly related to the stability of building structures. Among them, steel bars It is the main building material in our country. The strength of steel bars directly affects the structural strength of concrete. For example, the compressive performance of steel bars is directly related to the bearing capacity of concrete. Therefore, the compression test of steel bars is very important. [0003] Most of the exis...
