论平屋面的排水与找坡(国外英文资料) Drainage and slope finding of flat roof Introduction: Drainage generally adopts flat roof wall and Roof Sloping gutter peripheral itself two ways to solve. Key words: flat roof, rainwater, slope finding Drainage usually adopts flat roof wall and Roof Sloping gutter peripheral itself two ways to solve. A gutter in the wall or parapet, the facade is subject to certain constraints, can not be fully realized. In the roof parapet side ditch, and the contradiction of the roof beam, plate, deliberately groove structure is also difficult, also affect the room space, rely on less thick insulation (insulation) layer can not be cut, insulation (insulation) layer is also negative, holding the edge ditch (insulation) layer is also difficult to find the slope protection; deliberately thickened layer and insulation layer (insulation), like the underground garage to a thickened layer side ditch is not appropriate (see Figure 1). Therefore, there is the roof structure by looking for the slope, the building slope to solve, but because of the irregular plane, many changes, the structure for slope is limited, it is difficult to achieve. In addition, the top surface of the room is uneven and looks uncomfortable. Therefore, the construction of slope is easier and more flexible. The problem discussed here is limited to this. Figure 1 cut insulation (heat insulation) layer to form side ditch I. General principles of rainwater inlet setting 1. emission patterns A combination of roof, rainwater, platoon, platoon, or both. In order to facilitate maintenance and reduce leakage, less indoor space, the design should be used as far as possible outside the platoon, and when the large span outside the difficulty or building facade requirements can not row outside, the use of internal or mixed type. 2. of the catchment area calculation (1): roof catchment area of the roof is calculated according to the horizontal projection area of the roof. In the standpipe with 100 as an example
