Test device for fire and combustion characteristics of building wall insulation panels with adjustable and complex configurations

Abstract

The present invention provides a device for testing the fire and combustion characteristics of thermal insulation boards for building walls with adjustable and complex configurations. Rectangular support plates of the same size form a rectangular support plate group; two ends of the sides of the rectangular support plate group are respectively welded with a cardan shaft; One end away from the cardan shaft is respectively inserted into a telescopic rod support, and the telescopic rod is fixedly connected to the telescopic rod support; the telescopic rod support is fixed in a limit hole in a bottom platform by a limit screw On the base, the hinge configuration of the two support plates above can be fixed on the bottom platform through the three telescopic rod supports; the application of this technical solution can realize the study of various geometric wall configurations and environments Data collection for analysis of special fire spread behavior of building wall insulation panels under wind conditions.

Description

technical field [0001] The present invention relates to a field, in particular to a device for testing the fire and combustion characteristics of thermal insulation boards for building walls with adjustable complex configurations. Background technique [0002] With the rapid promotion of global environmental protection buildings and green buildings in the past 30 years, building wall insulation panels have been widely used in the construction field and various related industries. It can play the role of partial decoration, and has already had a huge impact on people's living and home furnishing. But at the same time, the raw materials used as building insulation boards are usually high molecular polymers, such as flexible polyurethane (FPU) foam boards, rigid polyurethane (RPU) foam boards, extruded polystyrene (XPS) foam boards, etc. These materials are composed of a large amount of hydrocarbon elements, and if not specially treated, they are extremely flammable, and the n...

Problems solved by technology

At present, most of the research methods and devices on the fire and combustion behavior of building insulation panels are aimed at the case of a single panel or a single configuration. Complex and diverse geometric configurations of modern buildings

Secondly, the environmental parameters or boundary conditions are not perfect enough, for example, the influence of environmental wind on building wall fires cannot be reflected, which is crucial for high-rise building fires

Therefore, the existing test devices and methods have limited the development of building fire safety science and the in-depth analysis of related combustion laws.
