Abstract

The invention provides a portable shear span section local electrochemical accelerated corrosion device and a steel beam corrosion system. The device is a rectangular corrosion tank 1 and comprises aplastic tank frame, a short plastic block 7 and a long plastic strip 6; he corrosion tank is a double-layer composite bottom and is provided with a rectangular tank into which the short plastic blockand the long plastic strip can be inserted; a transverse baffle 4 is installed on the upper portion of the corrosion groove, door-type plastic plates 2 of hinges 5 are installed at the two ends of thecorrosion groove, bolt holes 3 are pasted in the middle of the four corners of the corrosion groove, and sliding blocks 9 with threads can be inserted into the bolt holes. The system comprises a steel beam to be corroded, a direct-current power supply, a stainless steel plate, a supporting block for supporting the corrosion beam, a rubber basin, a cushion block for supporting the corrosion deviceand the corrosion tank. The portable shear span section local electrochemical accelerated corrosion device and the steel beam corrosion system are provided for the steel beam, and a good water leakage prevention effect can be provided when local corrosion occurs to the shear span section of the steel beam. When the rusting length changes, lengthening can be conducted, the length is adjustable, and the portability is good.

Description

technical field [0001] The invention relates to a portable local electrochemical accelerated corrosion device for a shear span and a steel beam corrosion system, belonging to the technical field of electrochemical corrosion tests. Background technique [0002] Steel structures in harsh environments such as salt lakes are prone to anti-corrosion coatings that are prone to aging and peeling off. Under certain conditions, electrochemical corrosion will occur, which will affect the service life and safety of the structure. Due to the leakage of rainwater, the change of the environment and location of the structure, the localized corrosion of the shear span is a typical corrosion condition of the steel beam. Therefore, for steel structures that have been in service for a long time, the durability problem caused by corrosion is worthy of attention. At present, it is a common method to study the mechanical degradation behavior of corroded steel beams by electrochemical accelerated...
