Abstract

The utility model discloses an anti-leakage roof drainage gutter and belongs to industrial and civil buildings. The anti-leakage roof drainage gutter is characterized in that steel wire balls are arranged on a horn opening of a water outlet pipe in the roof gutter, a cobblestone layer is paved in the roof gutter, the thickness of the cobblestone layer can be 100-150mm, the lower portion of the cobblestone layer is a big cobblestone layer with the thickness being 50-100mm, the upper portion of the cobblestone layer is a small cobblestone layer with the thickness being 50mm, a reinforced concrete water grate is placed on the small cobblestone layer after the small cobblestone layer is smoothened, the reinforced concrete water grates is cuboid and long-stripe-shaped water leaking openings are arranged in the reinforced concrete water grate in the length direction, namely that the water leaking openings are parallel to a wider edge of the water grate and two ends of each of the leaking openings are of a semicircular shape. The cobblestone layer has a heat retaining function, cracking of a proof insulating layer caused by change of temperature is reduced and phenomenon of leaking of the roof gutter of a building in later period is effectively reduced.

Description

The roof drainage gutter of preventing water leakage

Technical field

The utility model belongs to civil building, especially relates to a kind of roof drainage gutter of civil building.

Background technology

At present, in the roof building engineering, majority be deck construction complete after, do waterproofing course at structural level, the waterproofing course top is done insulation layer again, and the insulation layer top is done steel concrete and received surface layer, around roofing or vertically make drainage gutter, leader (outdoor falling into water and indoor falling into water) is set in the gutter bottom, and the suitable for reading and steel concrete of leader receipts surface layer upper surface is concordant; But because steel concrete receipts surface layer is generally thinner, and the bottom of receiving surface layer is the heat insulating material of different attribute, easily receive the surface layer be full of cracks after the construction because of variations in temperature, Sometimes When It Rains will infilter rainwater, because the draining under the insulation layer is not considered in design, at this moment the space of heat insulating material will store a large amount of rainwater, of long duration open valley will occur leak, and causes unnecessary loss and trouble.

Summary of the invention

The purpose of this utility model is the roof drainage gutter that proposes a kind of preventing water leakage, and is not only rational in infrastructure, uses reliably, guarantees that draining is unimpeded, chaps because of variations in temperature but also effectively reduce roofing, reduces the generation of roof leakage phenomenon.

The purpose of this utility model is achieved like this: a kind of roof drainage gutter of preventing water leakage, the deck that comprises roofing, waterproofing course and leader, deck at roofing arranges waterproofing course, and the bell-mouthed degree of depth that this waterproofing course is made into leader is no less than 50mm, the wide 400mm of being no less than is reserved in the corresponding position that is positioned at pre-buried leader on waterproofing course, the degree of depth is no less than the open valley of 200mm, it is characterized in that: on the horn mouth of each leader in the open valley, all place steel wire lump, in open valley, lay the cobble layer, the thickness of this cobble layer can be 100～150mm, the bottom of this cobble layer is the cobblestone layer of thickness 50～100 mm, the diameter of this cobblestone is 35～50mm, the top of this cobble layer is the pebble layer of thickness 50 mm, the diameter of this pebble is 20～35mm, the pebble layer is smoothed, place the steel concrete leaf grating for down pipe at the cobble layer, this leaf grating for down pipe is the along its length uniform strip scupper (being that each scupper is parallel with the broadside of leaf grating for down pipe) of offering of cuboid and centre, the two ends semicircular in shape of this scupper, the length of this leaf grating for down pipe * wide * thick 500mm * 400mm * 50mm that can be.

Like this, the cobble layer of laying has the effect of insulation, with regard to reduced all use thermal insulation material on the roofing integral roofing insulation layer done because of variations in temperature in the be full of cracks that gutter and roofing intersection form, effectively reduced the phenomenon of building roof gutter deuterogenesis seepage.

The roof drainage gutter of the preventing water leakage that the utility model proposes, not only rational in infrastructure, use reliably, guarantee that draining is unimpeded, but also effectively reduced roofing because of the be full of cracks that variations in temperature occurs, reduced the generation of open valley drainage.

The roof drainage gutter of the preventing water leakage that now in conjunction with the accompanying drawings and embodiments the utility model is proposed is described further.

Description of drawings

Fig. 1 is the principal section schematic diagram of the roof drainage gutter of the preventing water leakage that proposes of the utility model.

Fig. 2 is the part 2 of the roof drainage gutter of the preventing water leakage that proposes of the utility model: the master of leaf grating for down pipe looks schematic diagram.

Among Fig. 1, Fig. 2: 1, waterproofing course 2, leaf grating for down pipe 3, cobble layer 4, open valley 5, leader 6, deck 7, steel wire lump.

The specific embodiment

Such as Fig. 1, can find out among Fig. 2: a kind of roof drainage gutter of preventing water leakage, the deck 6 that comprises roofing, waterproofing course 1 and leader 5, deck 6 at roofing arranges waterproofing course 1, and the bell-mouthed degree of depth that this waterproofing course 1 is made into leader 5 is no less than 50mm, the wide 400mm of being no less than is reserved in the corresponding position that is positioned at pre-buried leader 5 on waterproofing course 1, the degree of depth is no less than the open valley 4 of 200mm, it is characterized in that: on the horn mouth of each leader 5 of 4 li of open valleys, all place steel wire lump 7, in open valley 4, lay cobble layer 3, the thickness of this cobble layer 3 can be 100～150mm, the bottom of this cobble layer 3 is the cobblestone layer of thickness 50～100 mm, the diameter of this cobblestone is 35～50mm, the top of this cobble layer 3 is the pebble layer of thickness 50 mm, the diameter of this pebble is 20～35mm, the pebble layer is smoothed, place steel concrete leaf grating for down pipe 2 at cobble layer 3, this leaf grating for down pipe 2 is cuboid and the centre uniform strip scupper (being that each scupper is parallel with the broadside of leaf grating for down pipe 2) of offering along its length, the two ends semicircular in shape of this scupper, the length of this leaf grating for down pipe 2 * wide * thick 500mm * 400mm * 50mm that can be.

Like this, the cobble layer 3 of laying has the effect of insulation, with regard to reduced all use thermal insulation material on the roofing integral roofing insulation layer done because of variations in temperature in the be full of cracks that gutter and roofing intersection form, effectively reduced the phenomenon of building roof gutter 4 deuterogenesis's seepages.
