Abstract

The invention relates to a high-temperature medium tensile deformation testing device for a concrete test sample and a deformation sensor clamp thereof. The deformation sensor clamp comprises an arc-shaped elastic piece, fixing seats and a measuring rod, wherein the fixing seats are arranged at two ends of the elastic piece; the measuring rod is arranged at the outer ends of the fixing seats and comprises a fire-resistant measuring end used for extending into a fire simulated furnace; clamping hoops which are provided with fastening screws and are used for clamping the deformation sensors andclamping rods or positioning rods with top plates are arranged on one sides of the fixing seats; the high-temperature medium tensile deformation testing device for the concrete test sample comprises at least two deformation sensor clamps with the previous structure. According to the testing device disclosed by the invention, the problem that the deformation sensor cannot directly test high-temperature medium deformation of the concrete test sample is solved.

Description

technical field [0001] The invention relates to a deformation sensor clamp in the field of concrete mechanical performance test and a high-temperature tensile deformation test device for a concrete specimen using the clamp. Background technique [0002] With the rapid development of high-rise buildings, fire problems have become increasingly prominent. In high-rise buildings, reinforced concrete structures account for more than 90%. As the main structural material, the mechanical properties of concrete will undergo a series of changes in the high temperature and high temperature of fire, such as the decrease of strength and elastic modulus, and the increase of deformation. As a load-bearing and supporting system of a building, its structure must maintain sufficient bearing capacity for a certain period of time so that the victims of the disaster can evacuate safely, and firefighters can extinguish the fire and rescue the casualties. Therefore, in order to effectively carry...
