Abstract

The invention discloses a multifunctional large-scale experimental device for preventing, controlling and blocking fire spreading on a vertical surface. The device comprises a steel profile-ceramic fiber board mixing experiment frame, the steel profile-ceramic fiber board mixing experiment frame is preset with an experiment material mounting holes, a thermocouple and a heat flow meter pre-buried hole, universal wheels are arranged at the bottom layer, and an exhaust fume collecting hood is arranged at the upper layer. A pipeline is connected with a gas acquisition system and is connected with a gas analyzer and a data acquisition system through pipelines; and an image acquisition system is arranged in the front of a building body, and a high-speed camera and an infrared camera are erected on the main vertical face and the side vertical face respectively. The device can be used for researching various related building thermal insulation curtain wall fireproof blocking technologies, simulating combustion phenomena and combustion rules of the thermal insulation curtain wall under various blocking technologies in a real fire scene, and exploring the effective fireproof blocking technology.

Description

technical field [0001] The invention relates to the technical field of fire safety, in particular to an experimental device for preventing and blocking fire spread on a multifunctional large-scale facade. Background technique [0002] High-rise buildings refer to residential buildings with a building height greater than 27m and non-single-storey factory buildings, warehouses and other civil buildings with a building height greater than 24m. The facades of high-rise buildings are usually covered with insulation materials, and common organic insulation materials such as polyurethane and polyethylene have the characteristics of low ignition point and fast fire spread. In recent years, with the increasing number of high-rise buildings, the fire situation in high-rise buildings has become more and more serious. The internal and external fires of high-rise buildings caused by building exterior wall insulation materials emerge in endlessly. The behavior and law of three-dimensiona...
