Embodiment 1
[0038] Embodiment 1: as Figure 1-11 As shown, a multi-layer partitionable atrium building fire smoke simulation experiment device, including the main body of the experimental device, the sprinkler system located on the main body of the experimental device, the smoke control system, the supporting measurement and control system, the telescopic device and the fuel in the fire room Supply device, controller;
[0039] The main body of the experimental device is a multi-storey building with an adjustable atrium space size, and the spatial layout is symmetrically distributed. A telescopic device is installed on the floor 12 on one side of the atrium space 25 on each floor. The telescopic device can cut off a certain floor. The fire room 31 is set on the front and back sides of the atrium space 12 on the first floor, and the left and right sides are escape passages and pipe wells 32. The escape passage includes the stairwell 30, the front room 29, and the elevator room 28. The fire ...

The invention relates to a multilayer partition atrium building fire smoke simulation experiment device, and belongs to the technical field of fire safety. The device comprises an experimental device main body, a spraying system arranged on the experimental device main body, a flue gas control system, a matched measurement and control system and a fuel supply device arranged on an ignition room, the device can be used for researching experiments of temperature, speed, pressure and motion path conditions of fire smoke in a large space structure of an atrium building under different fire loads under the conditions of different atrium space sizes, partition conditions, natural ventilation, mechanical smoke exhaust, spraying system opening conditions and ignition space positions, and can record related data and videos; the experimental device is specially used for comprehensively and systematically researching the flow characteristic, temperature distribution, pressure change and the like of fire smoke in the building with the atrium structure, and has a wide application prospect in the fire safety design of the atrium building.
Description
technical field [0001] The invention relates to a multi-layer partitionable atrium building fire smoke simulation experiment device, which belongs to the technical field of fire safety. Background technique [0002] Due to its excellent commercial application value, the atrium building mainly has the characteristics of tall appearance, sufficient light, large vertical space, and high comprehensiveness. It has been highly recognized by architectural designers and construction developers, especially in the past ten years. The number of atrium-style commercial buildings in my country continues to increase rapidly. But at the same time, the relatively complex internal structure and relatively tall space of atrium-style commercial buildings have brought certain challenges to fire prevention and smoke exhaust. [0003] The biggest feature of the atrium building is that it has one or more capped large spaces that run through several floors in the vertical direction. Traditional bu...
