Abstract
The utility model relates to roofing, particularly relates to positively fixed type roofing.A kind of positively fixed type roof vent pipe, positively fixed type roofing comprises roofing surface layer, waterproofing course, insulation layer and deck, the short steel pipes buried underground in deck below described steam vent position, short steel pipes bottom leans out structural layer lower surface, the hypomere that short steel pipes stretches out deck is arranged with PVC sleeve pipe, described PVC sleeve pipe passes into rainwater drainage pipe nearby downwards, and be a circle pervious concrete between steam vent and insulation layer, steam vent top end cover is established lid steel sheet and is fixed on vent ports.The utility model ensures the attractive in appearance of roofing, can not be destroyed, and ensures the heat insulation effect of insulation layer.
Description
Technical field
The utility model relates to roofing, particularly relates to positively fixed type roofing.
Background technology
(waterproofing course is upper for positively fixed type roofing, insulation, sloping layer under), owing to having certain steam to exist in roof panel and insulation sloping layer, therefore require that when doing waterproofing course heat insulation layer arranges dividing joint, thus the water existed in roofing is passed by dividing joint, generally one stack is set in right-angled intersection place of roofing dividing joint.
Tradition positively fixed type roof vent pipe root is embedded in insulation layer, and top must be stretched out roofing and is not less than 250mm, and exhaust tube wall must arrange additional waterproof course and add ferrule, painting encapsulant.To affect roofing attractive in appearance owing to stretching out roofing for this stack, and very easily destroyed, and after destroyed, rainwater can flow into insulation layer from extract duct and affect heat insulation effect.
Summary of the invention
The utility model is intended to the above-mentioned defect solving prior art, provides a kind of positively fixed type roof vent pipe.The utility model ensures the attractive in appearance of roofing, can not be destroyed, and ensures the heat insulation effect of insulation layer.
In order to solve the problems of the technologies described above, the utility model positively fixed type roof vent pipe, a kind of positively fixed type roof vent pipe, positively fixed type roofing comprises roofing surface layer, waterproofing course, insulation layer and deck, the short steel pipes buried underground in deck below described steam vent position, short steel pipes bottom leans out structural layer lower surface, the hypomere that short steel pipes stretches out deck is arranged with PVC sleeve pipe, described plastic bushing passes into rainwater drainage pipe nearby downwards, be a circle pervious concrete between steam vent and insulation layer, steam vent top end cover is established lid steel sheet and is fixed on vent ports.
Described positively fixed type roof vent pipe, rainwater drainage pipe nearby described in described PVC sleeve pipe leads to so that small angle is downward-sloping.
Described a kind of positively fixed type roof vent pipe, described short steel pipes outer wall is provided with ring-type wing plate (seal ring) and plays sealing effect to be stuck in deck.
The utility model solves positively fixed type roofing exhaust problem; Stack is placed in below roofing, is not easily destroyed; Roofing is given prominence to obstruction and is reduced, attractive in appearance; In roof waterproof layer local by accidental destruction situation, the rainwater entering insulation sloping layer can be discharged by this stack, reduces because insulation layer enters the sound of rainwater to roof heat insulation effect.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described:
Fig. 1 is the utility model schematic diagram.
Detailed description of the invention
As shown in Figure 1, the utility model positively fixed type roof vent pipe, a kind of positively fixed type roof vent pipe, positively fixed type roofing comprises roofing surface layer 1, waterproofing course 2, insulation layer 3 and deck 4, the short steel pipes 5 buried underground in deck below described steam vent position, short steel pipes bottom leans out structural layer lower surface, the hypomere that short steel pipes stretches out deck is arranged with plastic bushing 6, described PVC sleeve pipe passes into rainwater drainage pipe nearby downwards, be a circle pervious concrete 7 between steam vent and insulation layer, steam vent top end cover is established lid steel sheet 8 and is fixed on vent ports.
In order to complete draining task better, in an embodiment of the present utility model, rainwater drainage pipe nearby described in described plastic bushing leads to so that small angle (less than 5 °) is downward-sloping, fails in figure to express this angle.
Except controlling the angle of inclination of plastic bushing, in another embodiment, described short steel pipes outer wall is provided with ring-type wing plate 9 as seal ring and, to be stuck in deck 4, so can plays sealing effect.
Certain most preferred embodiment of the present utility model has above-mentioned two kinds of technical schemes concurrently.
Claims (3)
