【正文】 Analyses to detect the steel structure of building material Abstract: the article briefly introduces the construction steel structure material properties and detection methods, focusing on the steel structure detection method and quality detection method in this paper, the analysis, to ensure the quality of light steel structure, steel structure material performance into full play. Key words: steel structure inspection。 Steel structural materials。 Quality inspection。 Quality evaluation Steel structure detection in individual ascension detection technology at the same time, pay attention to the development and implementation of integration, perfect the plete steel structure detection technology, including steel mechanical properties tests (tensile, bending, impact, hardness) fasteners, mechanical performance testing, steel structure (sliding resistance coefficient, axial force), steel metallurgical testing analysis, microstructure analysis, microhardness testing), steel, chemical position analysis, nondestructive testing, steel structure steel structure stress testing and monitoring, coating testing such as plete sets of testing technology. A, steel structure material From the use point of view, strength, plasticity, weldability and cold short destructive is building the basic performance of steel. Monomial index of the material does not represent all of its features, must be based on the prehensive evaluation indicators of routine test. Assessment should also collect the following data for reference data: in the steel production of time, the supply of steel technology condition and product specifications. Must find out the steel grades, technical indicators, ultimate strength, yield strength, tensile elongation, cold, repeated bending, impact toughness, and chemical position, etc. Material inspection including steel profiles (including welding hbeam, welded pipe), welding, bolts ball and connection fasteners testing, material, welding, bolts ball is the basic elements of steel structure engineering, its quality is directly related to the quality of the project. Profiles, it is material to grow milling width of specimen and then stretch the cold bending test, the physical properties testing。 Welding ball is must be the diameter of the pipe welding according to the standard, then the tensile pressive tests are carried out。 Very similar to the bolt and the welding ball, but no pression test。 Connection fasteners, mainly is the high strength bolts for us. High strength bolt mainly control the quality of the project including the minimum load detection, pretension the reinspection, torque, the reinspection torque coefficient and coefficient of slip resistance test. Steel material mechanical test and chemical analysis results, should ply with the provisions of the corresponding procedures. B, steel structure detection (a) steel structure thickness of section is measured by thickness gauge Steel structure because of the influence of the processing accuracy and section of corrosion, the steel structure of the section thickness is often some changes. Especially corrosion section thinning, bearing capacity decreased, the structure safety degree of influence is very big. T
