Abstract
The utility model discloses a double-drain-pipe structure of a building roof. The double-drain-pipe structure comprises a first drain pipe (5), a vertical pipe (1) connected with the first drain pipe (5) and a second drain pipe (2), wherein the port at one end of the second drain pipe (2) is arranged on a slope making layer (4) of the building roof, the lowest end of the port is no higher than the lowest position of the slope making layer, and the port at the other end of the e second drain pipe (2) is communicated with the vertical pipe (1). The double-drain-pipe structure ensures organized drainage of the roof and facilitates discharging of water in a heat preservation layer and the slope making layer of the roof, the inside of the roof is ensured to be dry, and roof leakage is reduced.
Description
Technical field
The utility model relates to a kind of gutter of building roof discharge structure, particularly a kind of building roof.
Background technology
The roof structure on flat roof mostly is greatly 4 layers, comprises successively waterproofing course, insulation layer, leveling layer and sloping layer from top to bottom.It is the excessive and main temporary measure taked need lay flexible waterproof layer immediately time of water content in roof slope making or insulation layer that the roofing light aggregate on flat roof is looked for aqueous vapor discharging in slope or the insulation layer; after complete one, two year of construction, the roofing exhaust hole can be blocked by dust, dust storm etc. usually.Press standard drawing regulation, be not more than 36 square metres on the flat roof deck and just must establish a stack, so not only hinder people in the activity of roofing, and very easily be disturbed or shutoff does not sternly cause roof leakage, the while also affects the decoration impression effect of roofing very much.
Existing employing polyphenyl foam plate is done the flat roof deck that insulation layer, light aggregate are done sloping layer, because the waterproofing course on the insulation layer in use breakage can occur, so can cause rainwater invades in the insulation layer, time one is long, roofing insulation has just become " aquifer ", and like this, roofing has just become one " waterponding roof ", although seepage can not occur immediately at that time, stay very large hidden danger to this building.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of can be after roof waterproof layer damages, the double water-discharging outlets structure that prevents indoor seepage and discharge roofing heat-insulating layer, look for the building roof of moisture in the cortex.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is as follows:
A kind of Double water drainage tube structure of building roof, comprise a gutter and the standpipe that is connected this gutter, also comprise one the 2nd gutter, the least significant end that the port of the 2nd gutter one end is arranged on the sloping layer place of building roof and this port is not higher than the least significant end of described sloping layer, and the port of the other end is communicated with described standpipe.
According to an embodiment of the present utility model, described the 2nd gutter is arranged on described gutter bottom, and the 2nd gutter and gutter all have certain slope, and described the 2nd gutter connects described standpipe by a plastic three-way.The 2nd gutter is embedded in the parapet of described building when construction, and leans out described parapet, and preferably leaning out length is 10mm.
According to another embodiment of the present utility model, described the 2nd gutter and described gutter all vertically arrange, and described the 2nd gutter is communicated with described standpipe by an elbow and a plastic three-way.
Because the diameter of gutter and standpipe is different, so described plastic three-way is reducing tee.
The beneficial effects of the utility model are: will adopt so far roof slope making or the aqueous vapor exposed conduit discharging modes of insulation layer, change into the mode of being combined with dark discharging, after roof waterproof layer damages, can effectively discharge the ponding in roofing heat-insulating layer, the sloping layer.
Description of drawings
Fig. 1 is the schematic diagram of an embodiment of the utility model building roof Double water drainage tube structure;
Fig. 2 is the schematic diagram of another embodiment of the utility model building roof Double water drainage tube structure.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail:
From the utility model embodiment of Fig. 1～shown in Figure 2 as can be known, the Double water drainage tube structure of building roof of the present utility model comprises a gutter 5 and the standpipe 1 that is connected this gutter 5.Building roof should be flat roof deck and adopts in a organized way central drainage mode, in order to prevent roof ponding after the waterproofing course breakage, pre-buried the 2nd gutter 2 when 6 construction of building parapet, the least significant end that the port of port the 2nd gutter 2 one ends of the 2nd gutter 2 one ends is arranged on sloping layer 4 places of building roof and this port is not higher than the least significant end of described sloping layer, and the port of the other end is communicated with standpipe 1.The 2nd gutter 2 is generally the plastic pipe of diameter 50mm.
Referring to the embodiment of Fig. 1, the 2nd gutter 2 is arranged on gutter 5 bottoms, and equal horizontally sets and have certain slope, so that draining is more smooth.The port least significant end that gutter 2 is arranged in the sloping layer 4 is concordant with the least significant end of sloping layer.The 2nd gutter 2 connects standpipe 1 by plastic three-way 3.
The 2nd gutter 2 is embedded in when housing construction in the parapet 6 of building, and leans out parapet 6, generally leans out 10mm.
Referring to another embodiment of Fig. 2, the 2nd gutter 2 all vertically arranges with described gutter 5, and the port of the 2nd gutter 2 upper ends is concordant with sloping layer 4 least significant ends, and the 2nd gutter 2 is communicated with standpipe 1 by an elbow and plastic three-way 3.
Because the diameter of gutter and standpipe is different, so plastic three-way 3 is reducing tee.
Owing to being provided with the 2nd gutter at the structural slab place of being close to building roof, so when the waterproofing course on the insulation layer in use breakage occurs, the rainwater of invading in the insulation layer can be discharged smoothly from the 2nd gutter, can not make the roofing retaining, thereby has prevented the generation of roof roof leaking phenomenon.
In sum, content of the present utility model is not limited in the above-described embodiment, and those skilled in the art can propose other embodiment within technological guidance's thought of the present utility model, but this embodiment is included within the scope of the present utility model.
