Description

Technical Field

[0001] This utility model relates to the field of building materials technology, and in particular to a field testing box for the fire resistance performance of building materials. Background Technology

[0002] In the construction industry, gypsum board is an interior decoration material, generally used for partition walls, ceilings, floors, etc. However, if gypsum board does not meet the corresponding safety standards, it can aggravate the fire during a fire and even accelerate its spread. Therefore, understanding and testing the combustion performance of gypsum board is very important.

[0003] In actual fire resistance tests of gypsum boards, it was found that the fire resistance of these gypsum boards did not meet the expected requirements. Once the test conditions triggered their withstand limit, the gypsum boards would show obvious cracking. This cracking was not a localized small-scale damage, but rather a more serious disintegration. A large number of fragments and fine powder would fall into the interior of the test chamber. These fragments and fine powder not only affected the accuracy of the test results, but could also cause equipment malfunctions. In addition, gypsum boards come in different sizes, and the existing equipment is inconvenient to test gypsum boards of different sizes.

[0004] Therefore, there is an urgent need to provide on-site testing boxes for the fire resistance performance of building materials to solve the above problems. Utility Model Content
