Abstract

The invention discloses a test device for fire damage and cooling treatment of a steel cable structure. The test device comprises a high-temperature calcinator, a cooling device and a loading device,the high-temperature calcinator comprises a high-temperature calcinator inner wall and a high-temperature calcinator outer wall, the high-temperature calcinator is of two semicircular structures, andthe lower ends of the two semicircular structures of the high-temperature calcinator can be closed or separated. The loading device is a microcomputer-controlled electronic pressure testing machine, the two ends of the loading device are each fixedly provided with a clamping device used for clamping and fixing the two ends of a test piece, the high-temperature calcining furnace and the cooling device can move left and right along the loading device, the cooling device is provided with a plurality of water spraying openings, and the water spraying openings are connected with a temperature control type cooling water tank. Open fire heating and water spraying cooling are used, and the situation that the steel cable structure suddenly encounters big fire in the using process is simulated moretruly.

Description

technical field

[0001] The invention is used in the field of steel cable structure safety detection, and is used for a test device and a use method thereof which adopt different temperature open flame heating and water temperature cooling after the steel cable structure is damaged by fire. Background technique

[0002] With the development of my country's infrastructure, the application of steel cable structures in engineering is becoming more and more extensive. The mechanical performance index will change obviously. Especially after high temperature treatment, the steel cable structure is cooled by water at different temperatures, and its damage will be different; even if the same temperature water is used for cooling, the mechanical performance indicators such as yield strength and ultimate strength of the steel cable structure will be affected by different heating temperatures. influences. The mechanical performance indicators such as yield strength and ultimate strengt...
