Abstract

The invention provides a coiling type high-temperature stretching test clamp for a sheet-shaped material, relates to a stretching test clamp, and aims at solving the problem of the conventional building structure material high-temperature mechanical performance test that the true length variation in the stretching process cannot be detected and a normal-temperature stretching test clamp cannot beused normally. The coiling type high-temperature stretching test clamp for the sheet-shaped material comprises an upper clamp body, a lower clamp body and a test part, wherein the upper end of the upper clamp body and the lower end of the lower clamp body are connected to a stretching tester; the lower end of the upper clamp body is connected to the upper end of the lower clamp body through the test part. The coiling type high-temperature stretching test clamp for the sheet-shaped material is reasonable in size, simple, easy, reliable for high-temperature stretching test of the sheet-shaped material such as a building film, and capable of effectively performing high-temperature stretching test; the problem of effective clamping of the sheet-shaped material at the clamping end and the clampsize fitting can be solved; the clamp is applicable to the sheet-shaped material stretching test.

Description

technical field [0001] The invention relates to a tensile test fixture, in particular to a sheet material winding high-temperature tensile test fixture, which belongs to the technical field of sheet material mechanical testing. Background technique [0002] The experimental research and evaluation of high-temperature mechanical properties of building structural materials is of great significance in the field of building fire protection. At present, the research methods of high-temperature material properties test of traditional building materials such as steel and concrete are relatively mature, and the relevant research results have also been applied to the research of building fire protection. Membrane materials, as an emerging fifth class of building materials, are widely used in large-span structures due to their light weight, high light transmittance, and good anti-fouling and self-cleaning properties, but the research on the high-temperature mechanical properties of me...
