Description

Flat roof drainage structure with oblique eave opening

Technical Field

The utility model belongs to the technical field of the building, in particular to flat roofing drainage structure of oblique eaves mouth of roofing.

Background

Among the prior art, the drainage structures of the flat roofing of oblique eaves mouth of roofing is because of considering outer drainage factor, and the structure of adoption is that the main part is chosen to the oblique eaves mouth, and this kind of structure requires that the slope of oblique eaves mouth should be big as far as possible to make things convenient for the perpendicular water of gutter to fall the construction of mouth, however, this kind of structure is because the requirement slope of construction is bigger, and although the construction is more convenient, but has restricted the molding of oblique eaves mouth, difficult adaptation building form is to the requirement of the facade size and the form of oblique eaves mouth. The vertical parapet is made at the bottom of the oblique eaves mouth in order to reduce the problem that the slope is too small to construct, but the vertical modeling of the oblique eaves mouth is also influenced by the structure. In addition, because the oblique eaves mouth slope undersize, it is difficult to be under construction, and engineering quality is difficult to guarantee, has the problem of rainwater seepage.

Application number is CN 201620829162.0's utility model discloses a flat slope roofing handing-over drainage structures, include flat roofing structural layer, sloping roofing structural layer, enclose fender structural layer and manger plate eaves. However, the utility model discloses a problem that the difficult construction of flat roof drainage was not solved when oblique eaves mouth angle was less yet.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problem overcome prior art weak point and defect, provide and can properly solve the difficult problem of flat roofing drainage construction when oblique eaves mouth angle is less, guarantee oblique eaves mouth facade molding and reduce a flat roofing drainage structures of oblique eaves mouth of rainwater seepage risk.

The utility model discloses a technical scheme include flat roofing structural layer, oblique eaves mouth structural layer, fill, downpipe and heat preservation decorative layer that falls into water, hang oblique eaves mouth decoration tile on oblique eaves mouth structural layer, be equipped with the breakwater at the open end of flat roofing structural layer and oblique eaves mouth structural layer the last plane of the flat roofing structural layer in the outside of breakwater is equipped with leads the water slope all be equipped with the drain pipe preformed hole on breakwater, flat roofing structural layer and the heat preservation decorative layer to install L shape drain pipe in the preformed hole that is equipped with on breakwater, flat roofing structural layer and the heat preservation decorative layer the perpendicular position below installation fill and the downpipe that falls into water of L shape drain pipe, the contained angle between flat roofing structural layer and the oblique eaves mouth structural layer 3 is α.

The included angle α between the flat roof structure layer and the oblique eave structure layer is 15-45 degrees.

The oblique eave structure layer is arranged on the flat roof structure layer, and the oblique eave structure layer is arranged on the flat roof structure layer.

Compared with the prior art, the beneficial effects of the utility model are that, owing to adopt to be equipped with breakwater and L shape drain pipe at the open end of flat roofing structural layer and oblique eaves mouth structural layer, the drainage does not receive oblique eaves mouth's angle restriction, does not need to do gutter and eaves gutter again, so simple structure, construction convenience, engineering quality guarantees easily, does not have the problem of rainwater seepage, can effectively cooperate the figurative needs of facade, guarantees the facade of oblique eaves mouth and models, has effectively solved the drainage problem of the flat roofing of oblique eaves mouth.
