Description

Technical Field

[0001] The utility model relates to the technical field of building material performance detection, in particular to a building thermal insulation material performance detection device. Background Art

[0002] Building insulation materials are made by taking measures on the building's exterior envelope to reduce the dissipation of indoor heat from the building to the outdoors, thereby maintaining the building's indoor temperature. Building insulation materials are usually made from a composite of insulation boards made of a variety of different materials during production. In order to ensure the quality of the insulation materials, the insulation boards are usually tested for their compressive properties.

[0003] Some existing related devices usually have relatively simple material fixing fixtures. Therefore, when testing prefabricated materials of different sizes, if the fixture cannot be changed, the prefabricated materials need to be uniformly processed before testing. Some materials will inevitably be wasted during the processing, increasing the testing cost. At the same time, when these devices are used, each material is usually tested one by one, which is time-consuming and costly, and is not conducive to comparative analysis. Therefore, technical personnel in this field provide a building insulation material performance testing device to solve the problems raised in the above background technology. Utility Model Content
