A kind of roofing water falls a mouthful node waterproof structure
Technical field
The utility model relates to building roof waterproof fields more particularly to a kind of roofing water to fall a mouthful node waterproof structure.
Background technique
Water falls mouth, is the dress collected in roofing or flooring functional in organized water drainage mode, rain water on roof is guided to flow into drainpipe
It sets.Because it is different from the material of gutter, eaves gutter that water falls mouth, falls water between mouth and eaves gutter and be easy to generate crack, lead to roofing
There is flaw in waterproof effect, and accelerates the corrosion that mouth is fallen to water, reduces water and falls a mouthful service life.
Utility model content
The purpose of this utility model is that in view of the drawbacks of the prior art and insufficient, providing a kind of roofing water, to fall mouthful node anti-
Water-bound, not only overall structure fitting is firm for the structure, while being provided with multi layer waterproof, and structure is simple, easy for construction.
In order to achieve the above purposes, the technical solution adopted by the utility model is:, and a kind of roofing water falls a mouthful node waterproof structure,
It include that top plate, water fall cup, surface layer;The top plate is building roof roof support with reinforced concrete structure, and building on the top plate has
Styrofoam layer;Fitting is equipped with haydite concrete sloping layer on the styrofoam layer;The water falls cup through top plate, styrofoam
Installation, the water fall that cup top is divided into hollow and thin-walled inverted round stage structure and top is provided in the middle part of layer and haydite concrete sloping layer
One circle evagination, lower part is divided into hollow and thin-walled cylindrical structure;The top plate, haydite concrete sloping layer and water, which are fallen between cup, to be all provided with
It is equipped with a fixed gap, perfusion, which is built, in the gap pea gravel concreten insertion layer;The waterproof layer fitting is laid on haydite coagulation
Native sloping layer top surface, the waterproof layer are pasted into certain distance in cup at the top of overboard cup;Building on the waterproof layer has concrete
Surface layer, which, which corresponds to water and fall cup top arcuate top side location and build, pea gravel concreten pier;It is right in the middle part of the surface layer
Ying Shui falls cup position and is provided with circular hole, is equipped with water inside circular hole and falls cup lid, and it is latticed thread which, which falls cup hd top face,
Hollow structure.
It is fallen between cup lid and surface layer preferably, the water falls gap, water between cup and pea gravel concreten insertion layer
Gap is filled with modified pitch sealing compound.
Preferably, the waterproof layer is pasted into 60mm-70mm in cup at the top of overboard cup.
The beneficial effects of the utility model are: not only overall structure fitting is firm for the structure, while it being provided with multi layer waterproof,
And structure is simple, it is easy for construction.
Detailed description of the invention
Attached drawing described herein is to be used to provide a further understanding of the present invention, and constitutes one of the application
Point, but do not constitute the restriction to the utility model.
Fig. 1 is that water falls mouth structure schematic diagram.
Wherein: 1 is top plate, and 2 fall cup for water, and 3 be surface layer, and 1-1 is styrofoam layer, and 1-2 is haydite concrete sloping layer,
1-3 is waterproof layer, and 1-4 is pea gravel concreten insertion layer, and 2-1 is that water falls cup lid, and 3-1 is pea gravel concreten pier.
Specific embodiment
In conjunction with attached drawing, the utility model is described in further detail.
It include that top plate, water fall cup, surface layer as shown, a kind of roofing water falls a mouthful node waterproof structure;The top plate
For building roof roof support with reinforced concrete structure, building on the top plate has styrofoam layer;It is bonded and is equipped on the styrofoam layer
Haydite concrete sloping layer;The water falls cup installation in the middle part of top plate, styrofoam layer and haydite concrete sloping layer, the water
Fall that cup top is divided into hollow and thin-walled inverted round stage structure and top is provided with a circle evagination, lower part is divided into hollow and thin-walled cylinder knot
Structure;The top plate, haydite concrete sloping layer and water, which are fallen between cup, is provided with a fixed gap, and perfusion is built and had in the gap
Pea gravel concreten insertion layer;The waterproof layer fitting is laid on haydite concrete sloping layer top surface, and the waterproof layer is along overboard cup
Top is pasted into certain distance in cup;Building on the waterproof layer has concrete topping, which corresponds to water and fall at the top of cup
The build of evagination top side location has pea gravel concreten pier;Corresponding water falls cup position and is provided with circular hole in the middle part of the surface layer, in circular hole
Portion is equipped with water and falls cup lid, and it is latticed thread hollow structure which, which falls cup hd top face,.
When it is implemented, the water falls gap between cup and pea gravel concreten insertion layer, water falls cup lid and surface layer it
Between gap be filled with modified pitch sealing compound.
When it is implemented, the waterproof layer is pasted into 60mm-70mm in cup at the top of overboard cup.
