Tensile test device and heating device

Abstract

The invention relates to a tensile test device and a heating device, and the tensile test device comprises the heating device and a tensile test machine, wherein the tensile test machine comprises loading heads capable of moving oppositely and reversely, the heating device comprises a heating furnace bracket and a heating furnace guiding and moving front and rear and assembled on the heating furnace bracket, the heating furnace is provided with at least two test piece perforations perforating through the upper furnace wall and the lower furnace wall of the heating furnace in the up-and-down direction, the respective test piece perforations are arranged at intervals in the front-rear direction, and the heating furnace is provided with a fixing device corresponding to the test piece perforations for detachably fixing the tensile test pieces in the test piece perforations. The invention solves the problem in the prior art that the tensile test pieces need to be separated from the heatingdevice to cause temperature loss during the tensile test, and can simultaneously heat two or more tensile test pieces.

Description

technical field [0001] The invention relates to a tensile test device for performing a tensile test on a tensile test piece in a high-temperature environment. Background technique [0002] In recent years, with the development trend of high-rise, long-span, lightweight and durability in the field of civil engineering, steel fiber-containing concrete materials such as steel fiber concrete and ultra-high performance concrete have been used in high-rise buildings, complex structures, and large buildings. Span bridges, special conditions of use and harsh environments (such as offshore platforms, subsea tunnels, nuclear facilities and military protection projects) are more and more widely used in fields such as steel fiber concrete, ultra-high performance concrete and other materials. New requirements have been put forward, and the research on its fire resistance has also become a hot spot. [0003] The degradation of mechanical properties of steel fiber reinforced concrete and ...
