Embodiment Construction
[0025] In order to have a further understanding and understanding of the structural features of the present invention and the achieved effects, the preferred embodiments and accompanying drawings are used for a detailed description, as follows:
[0026] like figure 1 As shown, an experimental device for studying fire spread of thermal insulation materials under ambient wind conditions according to the present invention includes a main body support 1 and a sample support 2, and the main body support 1 and the sample support 2 are mirror images. In order to facilitate the movement of the main body support 1 and the sample support 2, four rollers 20 can be installed at the bottom of the main body support 1; four pulleys 21 can also be installed at the bottom of the same sample support 2. An ambient wind tilting assembly is installed on the main frame 1, and the ambient wind tilting assembly is used to adjust the wind direction of the ambient wind, and an ambient wind generating ...

The invention relates to an experimental device for studying fire spread of a thermal insulating material under an ambient wind condition. Compared with the prior art, the experimental device solves the defect that no experimental device for studying fire spread of thermal insulating materials under the ambient wind condition is available. A vertical movement component is mounted on a sample bracket of the experimental device, a support platform is mounted on the vertical movement component, two rotating shaft support bases are arranged on the support platform, sample rotating shafts are mounted on the rotating shaft support bases and are in rotational matching with the rotating shaft support bases, ceramic fiber plates are fixedly mounted on the sample rotating shafts, a turbine worm speed reducer A is fixedly mounted on the support platform, the output shaft of the turbine worm speed reducer A is horizontally connected with a sample rotating shaft, and a rotating handle A is mounted on the input shaft of the turbine worm speed reducer A. By adopting the experimental device, fire spread of the thermal insulating material can be studied under the multi-angle ambient wind condition, and moreover, the wind speed, the wind direction and the placing angle of a sample material can be controlled.
Description
technical field [0001] The invention relates to the technical field of fire prevention performance research of building materials, in particular to an experimental device for studying fire spread of thermal insulation materials under ambient wind conditions. Background technique [0002] With the rapid development of my country's economy and the acceleration of urbanization, my country's construction industry is developing rapidly. In response to my country's increasing building energy-saving requirements, organic exterior wall insulation materials are widely used in building exterior walls, and their economic benefits and thermal insulation properties are excellent. was unanimously approved. However, due to the structure of the organic insulation material itself, its fire resistance is poor, and it is easy to burn. Once it catches fire, it will generate a lot of heat to promote the rapid spread of the fire, and a large amount of toxic and harmful smoke will be produced dur...
