Fire-fighting emergency top-attaching smoke exhaust through hole device
The invention relates to a fire-fighting emergency top-attaching smoke exhaust through hole device, which is characterized in that each independent fireproof subarea of a building and each closed and semi-closed functional unit in a single fireproof subarea are built, or each closed and semi-closed functional unit is divided into a plurality of smaller functional areas, each layer of corridor area, each layer of staircase area or spacing layer area; an independent top-attached smoke exhaust channel leading to the external atmosphere is arranged, the channel is attached to the top, a hole is formed in the wall beam plate in the top-attached mode in the smoke exhaust flow direction, and the top face of the channel horizontally and gradually ascends and does not descend. The fire-fighting emergency ceiling-attaching smoke-discharging through hole device is composed of two parts, namely a ceiling or a top plate surface in the upper area of a space where a smoke discharging channel area is located and an adjacent edge enclosing part, and a through hole part which is tightly attached to the ceiling or the top plate surface and is embedded into a wall beam plate. The through hole part is composed of a through hole ring, an opening structure reinforcing part, baffles at the two ends of the through hole, an automatic emergency opening and closing mechanism linked with the baffles and a rainproof and windproof outwards-protruding part extending out of the outer wall.
本发明涉及一种消防应急贴顶排烟通孔装置，建构筑物每个独立的防火分区，和单个防火分区内各封闭半封闭的功能单元或其分隔成多个更小的功能区域，每层楼道走廊区域，楼梯间每层区域或间隔层区域，设置独立的通向外部大气的贴顶排烟通道，通道贴顶，沿排烟流向在墙梁板件贴顶开孔，通道顶面水平逐步上升且不下降。本消防应急贴顶排烟通孔装置，由两部分组成，排烟通道区所在空间上部区域的天花板或顶板板面及其邻近边缘围合部分，和紧贴天花板或顶板板面的嵌入墙梁板件上的通孔部分。通孔部分构成为通孔环圈、开孔结构补强部分和通孔两端挡板及挡板联动自动应急启闭机构，以及伸出外墙的防雨防风的外突部分。
