Description

The inverted roof of band weeper drain

Technical field

The utility model relates to a kind of building roofing, particularly a kind of inverted roof with weeper drain.

Background technology

The roofing of traditional reinforced concrete structure is made up of floor slab structure layer, sloping layer, waterproofing course, insulation layer, topping and surface layer etc. usually.Way waterproofing course in the past is made in above the insulation layer, still often easily causes the local damage of waterproofing course owing to the reason of structure and construction aspect, causes seepage and has a strong impact on heat insulation effect.

Recently inverted roof way commonly used is that insulation layer is laid on the waterproofing course, this has improved the execution conditions of waterproofing course to a certain extent, but waterproofing course tends in default of the water proof structure facility with top in this case, cause moisture to permeate toward following surface layer by roofing layer, alluvial is on waterproofing course, and easily further be penetrated into down one deck, and destroy original roof structure, cause the damage of structure.

The utility model content

Technical problem to be solved in the utility model is, a kind of inverted roof with weeper drain is provided, and the moisture alluvial of avoiding down permeating in the existing inverted roof causes structure to damage on waterproofing course, so that the technical problem of roof leakage.

The technical solution of the utility model is; a kind of inverted roof with weeper drain is provided; comprise deck, waterproofing course, insulation layer, topping and surface layer; described insulation layer is on described waterproofing course; described waterproofing course and insulation layer have the gradient; and the gradient low side of described insulation layer is provided with weeper drain, and described weeper drain itself has the gradient, and the low side of the weeper drain gradient is communicated with drainage pipe.

In the inverted roof of above-mentioned band weeper drain, the gradient of described waterproofing course and insulation layer is by the sloping layer that is provided with under the waterproofing course or directly adopt roof structure to look for domatic to become.

In the inverted roof of above-mentioned band weeper drain, be the roofing edge at the low side of the above-mentioned gradient, described weeper drain is positioned at the roofing edge.

In the inverted roof of above-mentioned band weeper drain, the above-mentioned gradient is roughly 2%.

In the inverted roof of above-mentioned band weeper drain, the gradient scope of described weeper drain itself is 0.5%～1%.

In the inverted roof of above-mentioned band weeper drain, be coated with topping and surface layer on the described weeper drain, organize draining in a organized way on the surface layer as required.

In the inverted roof of above-mentioned band weeper drain, the cross section of described weeper drain is wide, height is respectively 150 * 30mm, the cobble of interior shop nonwoven parcel.

The inverted roof of band weeper drain of the present utility model by weeper drain is set, has been guaranteed the drying of roof structure layer, has avoided alluvial water that techonosphere is damaged, thereby has improved heat insulation effect, and effectively reduced the situation of roof leakage.

The specific embodiment

As shown in Figure 1, the inverted roof of band weeper drain of the present utility model is by floor slab structure layer 11, sloping layer 12, compositions such as waterproofing course 13, insulation layer 14, topping 15 and surface layer 16.Above-mentioned each layer laid from top to bottom successively, wherein also can adopt roof structure to look for the slope and do not establish sloping layer.Below be that example is introduced the utility model with the way that sloping layer is set.

Insulation layer 14 on the waterproofing course 13 adopts the water proof type heat insulating material, do not deposit in insulation layer 14 to guarantee the water that down permeates from surface layer, but alluvial is on waterproofing course 13.Be close to below the waterproofing course 13 and be sloping layer 12, the gradient operated by rotary motion of sloping layer 12 is 2% about (depth-width ratio that is the cross section is 2: 100, down with), thereby makes waterproofing course 13, the insulation layer 14 of sloping layer more than 12 all have the gradient about 2%.

The lower position of the gradient that forms on insulation layer 14, by sloping layer 12 is provided with weeper drain 17.Because action of gravity, the water of alluvial on waterproofing course 13 can be along the slope from the high-end weeper drain 17 that flows to low side.Weeper drain 17 is communicated with roof drainage pipeline 19 by downward-sloping conduit 18, thereby water is discharged.What fail among the figure to express is, on the direction vertical with this drawing, by sloping layer 12, makes weeper drain 17 itself also have the gradient simultaneously, and the low side of the gradient then is a conduit 18.The gradient scope of above-mentioned weeper drain 17 is 0.5%～1%.

In the present embodiment, the way of weeper drain 17 is: wide, the height in cross section are respectively 150 * 30mm, the cobble of interior shop nonwoven parcel, and it is the specification of 5～8mm that cobble adopts particle diameter.At roofing periphery (being the inboard and last roofing threshold of the parapet outside among the embodiment) weeper drain of perforation is set, sentences circular-arc avoiding there being side to arrange floor drain.Water in the weeper drain 17 passes parapet according to the direction of arrow among Fig. 1 with the DN50PVC gutter and inserts the exterior wall rain leader downspout.Certainly weeper drain 17 also can adopt other structures or size, as the structure of hollow etc.

As shown in Figure 2, the gradient low side of roofing is generally the roofing edge, and promptly the low side of the incline structure of waterproofing course 13 is at the roofing edge.Correspondingly, weeper drain 17 also is arranged at roofing edge.Arrow among this figure only is used to represent flow into the flow direction of the water of weeper drain 17.

As shown in Figure 3, in flat roof, high both sides were low in the middle of sloping layer 12 gradients were set to, and at both sides downside correspondence position weeper drain 17 can be set respectively.Similarly, the arrow among this figure also only is used to represent flow into the flow direction of the water of weeper drain 17.In addition, sloping layer 12 is provided with also can look for the slope toward each edge of roofing as shown in Figure 4, and can at each edge correspondence position of roofing weeper drain 17 be set, the example that is provided with many weeper drains 17 as shown in Figure 4.

Look among the embodiment on slope at the employing room panel structure, because floor slab structure layer 11 itself has the gradient, make waterproofing course 13, insulation layer 14 on it all have the gradient, thereby the weeper drain 17 of gradient low side that can be by being arranged on insulation layer 14 compile the water that accumulates on the waterproofing course 13 and discharge.
