Atmospheric corrosion exposed test stand

Abstract

The invention discloses an atmospheric corrosion exposed test stand and relates to the technical field of corrosion resistance, aiming at preventing the test stand from being falling from a mounting part of a building under an extreme weather condition. The atmospheric corrosion exposed test stand is erected at the mounting part of the building and comprises a base, wherein a fixing frame for fixing a metal test piece is arranged at the mounting part of the base; the fixing frame is used for fixing the metal test piece; an included angle between the surface of the metal test piece and the horizontal plane is a testing angle and the testing angle is an acute angle; the base is detachably connected with a fastening part; and a clamping sleeve which is tightly clamped with the mounting part of the building is formed by surrounding the fastening part and the base. The atmospheric corrosion exposed test stand provided by the invention is used for monitoring buildings with atmospheric corrosion resisting capabilities in site for a long period.

Description

technical field [0001] The invention relates to the technical field of corrosion resistance, in particular to an atmospheric corrosion exposure test rack. Background technique [0002] Metal material is a material with good plasticity and mechanical strength, which is widely used in various buildings; and when people design engineering, they generally choose metal materials with better atmospheric corrosion resistance to be used in building materials to Improve the environmental adaptability of metal materials, thereby increasing the service life of buildings. Therefore, construction units pay great attention to the performance index of atmospheric corrosion resistance of metal materials. [0003] In order to study the atmospheric corrosion resistance of metal materials in buildings, people usually fix the atmospheric corrosion exposure test frame on the cement floor in the atmospheric corrosion test station, and set the metal test piece on the atmospheric corrosion exposure...

Problems solved by technology

[0003] In order to study the atmospheric corrosion resistance of metal materials in buildings, people usually fix the atmospheric corrosion exposure test frame on the cement floor in the atmospheric corrosion test station, and set the metal test piece on the atmospheric corrosion exposure test frame, and manage it by a special person. , to monitor the atmospheric corrosion resistance of metal materials, but the monitoring conditions of this monitoring method are relatively stable, and can only monitor the atmospheric corrosion resistance of building metal materials with relatively stable environment and single atmospheric corrosion ability; Buildings for long-term on-site monitoring of atmospheric corrosion resistance, such as power transmission line towers, need to set up the atmospheric corrosion exposure test on the power transmission line towers to conduct atmospheric corrosion exposure tests of metal test pieces, but the existing atmospheric corrosion exposure test stand The frame structure is complex, bulky, and extremely inconvenient to move. It is not convenient to carry out on-site test on the transmission line pole several meters above the ground; moreover, in the process of long-term on-site atmospheric corrosion exposure test of metal test pieces, encounter When encountering various meteorological conditions, such as typhoons, heavy rains and other similar extreme weather conditions, due to the large volume of the test frame exposed by atmospheric corrosion, it is easy to fall off from the transmission line tower, which leads to the failure of the test
