Slotting type ventilation and heat insulation roof system for building energy-saving transformation
The invention discloses a slotting type ventilation and heat insulation roof system for building energy-saving transformation, and relates to the technical field of building structures, the slotting type ventilation and heat insulation roof system comprises a ventilation and heat insulation component, the ventilation and heat insulation component comprises a skin erected on the outer side of an existing roof, and the skin is arranged in an elevated mode so as to form a ventilation cavity located between the skin and the existing roof, the skin is provided with a plurality of slots, the slots are communicated with the ventilation cavity so that air in the ventilation cavity can pass through the slots to achieve hot-pressing ventilation in the vertical direction, the ratio of the sum of the slot areas to the surface area of the skin is defined as the slot ratio, and the slot ratio is larger than 0 and smaller than 14%. Hot-pressure ventilation in the vertical direction and wind-pressure ventilation in the horizontal direction in the ventilation cavity can be considered, and the heat dissipation effect of the existing roof is improved.
本发明公开了一种用于建筑节能改造的开缝式通风隔热屋面系统，涉及建筑结构技术领域，包括通风隔热部件，通风隔热部件包括架设在既有屋面外侧的表皮，表皮架高设置，以形成位于表皮与既有屋面之间的通风空腔，其中，表皮设置有多条开缝，各开缝连通通风空腔，以使通风空腔内的空气通过各开缝实现竖直方向的热压通风，开缝面积总和占表皮表面积的比率定义为开缝比率，开缝比率大于0且小于14％。本申请能兼顾通风空腔内竖直方向的热压通风与水平方向的风压通风，提高既有屋面的散热效果。
