Description

Technical Field

[0001] This utility model relates to the field of building material testing technology, and more specifically to a high-temperature performance testing device for profiled steel sheet composite floor slabs. Background Technology

[0002] Corrugated steel sheet composite floor slabs are an important structural element in modern construction engineering, widely used as a load-bearing structure to significantly improve the building's seismic resistance, stability, and construction efficiency. However, in practical applications, these slabs often need to withstand high-temperature environments, especially in extreme conditions such as fires. Therefore, testing their performance under high temperatures is particularly important.

[0003] Traditional performance testing methods for profiled steel sheet composite floors primarily focus on their mechanical properties and durability at room temperature, with less attention paid to performance changes under high-temperature environments. Existing testing equipment often cannot simulate real fire environments, leading to significant discrepancies between test results and actual conditions. Furthermore, while some testing devices can simulate high-temperature environments, they typically only heat or pressurize one side of the specimen, failing to comprehensively reflect the complex stress conditions of profiled steel sheet composite floors under actual fire conditions.

[0004] Therefore, it is necessary to propose a high-temperature performance testing device for profiled steel composite floor slabs to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to develop a testing device that can simultaneously heat and pressurize the profiled steel sheet composite floor slabs under high-temperature conditions such as fires, in order to more realistically simulate the performance of the slabs. Such a device can not only more accurately evaluate the mechanical properties and deformation characteristics of the profiled steel sheet composite floor slabs under high temperatures, but also provide a more reliable basis for their application in engineering design and construction.
