Problems solved by technology
[0009] The technical problem to be solved by the present invention is that the existing combustion vertical furnace used for the fire resistance test of building components has poor sealing performance, cannot effectively observe the real-time state of the building components to be tested during the experiment, and is difficult to effectively collect the gas in the furnace body. The technical disadvantage of temperature, the combustion vertical furnace used in the fire resistance test of building components provided by the present invention has good sealing performance, is easy to observe the real-time state of the sample to be tested in the combustion furnace, and can effectively collect the temperature data of the combustion furnace

The invention relates to a combustion vertical furnace for a fire resistance test of a building component. The combustion vertical furnace comprises a furnace body and a sample bracket. The combustion vertical furnace is characterized in that the furnace body is in a box shape, the foundation part of the furnace body adopts a C20 reinforced concrete ground floor with a thickness of 200mm, the surface of the ground floor around a test furnace is plastered with cement mortar with a proportion of 1:2, and an embedding piece adopts steel material. The combustion vertical furnace for the fire resistance test of the building component has the advantages that the sealing performance is improved; the outward leakage of fume is avoided; the states of a sample to be tested can be observed through an observing window in a real-time way; the measuring accuracy is ensured; and combustion data is favorably collected.
Description
technical field [0001] The invention relates to a detection device for a fire resistance test of a building component, in particular to a combustion furnace used for a fire resistance test of a building component. Background technique [0002] The safety performance of building components is an important indicator of building fire safety. The fire resistance of building components is related to the safety of buildings. Therefore, before building components are put into use, they need to be tested for safety and fire performance indicators. The National Standard of the People's Republic of China "Building Components Fire resistance test method "GB / T 9978.1-9-2008 stipulates the test device, test conditions, test piece requirements, test procedures, fire resistance limit judgment conditions and test report content of the fire resistance test of building components. The standard is applicable to load-bearing and non-load-bearing components such as walls, beams, columns, floors,...
