Site detection equipment for mechanical property of steel bars

Abstract

The invention discloses site detection equipment for mechanical properties of steel bars. The site detection equipment comprises a clamp, a base and a supporting device, wherein the clamp and the base are respectively provided with a first installing hole and a second installing hole which are coaxial; at least one of the first installing hole and the second installing hole is internally provided with a steel-bar fixing and clamping device; the supporting device can drive the clamp to move relatively to the base along the axial direction of the first installing hole and the second installing hole. The site detection equipment disclosed by the invention has the advantages that the structure is simple, the assembly is convenient, the steel bars in various states in engineering can be detected, the accuracy of the detection results of the steel bars can be ensured and the quality of engineering construction is guaranteed.

Description

technical field [0001] The invention relates to a testing device for the mechanical properties of steel bars, in particular to an on-site testing device for the mechanical properties of steel bars. Background technique [0002] For concrete structures, the mechanical properties of steel bars are the most important indicator of their load-bearing performance. Therefore, testing the mechanical properties of steel bars is an important means to ensure their quality. Structural engineering requires the re-inspection of the mechanical properties of steel bars, especially for joints that are welded or mechanically connected. However, the current displacement detection is realized by adding a displacement extensometer. This kind of equipment realizes the tensile performance test of the steel bar through the hydraulic system, and has the function of strictly controlling the loading speed. In the actual binding, some steel bars are arranged horizontally, some are vertically arranged,...

Problems solved by technology

However, the current displacement detection is realized by adding a displacement extensometer. This kind of equipment realizes the tensile performance test of the steel bar through the hydraulic system, and has the function of strictly controlling the loading speed. In the actual binding, some steel bars are arranged horizontally, some are vertically arranged, and some are even arranged obliquely, and the steel bars are long. Even if the equipment is moved to the site, the test cannot be carried out. Therefore, the mechanical performance testing of all related steel bars All require indoor inspection, which is meaningful for material type inspection or factory inspection, which requires the control of the testing equipment environment, but for engineering, the significance is not very obvious

In addition, due to the lack of a social integrity system, the current engineering material testing requirements in my country are witness sampling testing. It is difficult to guarantee the authenticity of whether the sample represents the mother parent. Many have done special processing, especially welding. The quality of the welded joints produced by the actual project (direct welding on site, see the photo) is uncontrollable. Strict regulations have been made. After each test, these test samples can only be sent to the steelmaking plant as waste products for re-smelting, resulting in a lot of waste of resources.
