The layer gaps shown in the figures are not actually present and the illustrations are intended to distinguish clearly between the layers. The material of the heat-insulating layer can be various, and typical materials include rigid polyurethane foam plastics, polystyrene foam plastics, hydrophobic expanded perlite, H-shaped foam plastic glass and the like. The roof receives the rainwater, the influence of snow, can the seepage income water, the heat preservation is the biggest layer body of trapped water volume, prior art is that the measure of depositing water for getting rid of the heat preservation is directly to insert at the heat preservation and establishes like the blast pipe 5 shown in fig. 5, wear each layer on the blast pipe, the export is located roof the superiors top, the intraformational water of heat preservation passes through the blast pipe with the gaseous state mode and discharges, it is slow to do drainage speed like this, low efficiency, the effect is poor, often can lead to the aspect inflation because of the heat preservation water content is too big, destroy the roof waterproof layer, something still can cause the roof to.

SUMMERY OF THE UTILITY MODEL

The utility model discloses it is slow to solve prior art roof heat preservation drainage speed, and the poor problem of effect provides for this reason the utility model discloses a roof drainage structure, this structure drainage is fast, and is effectual.

In order to solve the problem, the utility model discloses a technical scheme, its special character is that heterotypic drainage and exhaust pipe has been buried underground at the roof heat preservation, and this heterotypic drainage and exhaust pipe has the arched body of cross section, and this arched body both sides respectively link there is the pterygoid lamina below the through-hole of arranging according to arched body length direction is seted up to the both sides wall of arched body, heterotypic drainage and exhaust pipe's connecting portion have the coupling, and the upside of this coupling has the gas outlet, even has the blast pipe on this gas outlet, and this blast pipe upwards wears out, and the export is located the roof top.

Furthermore, geotechnical cloth is wrapped on the special-shaped drainage and exhaust pipe.

The pipe joint is a two-way pipe joint, a three-way pipe joint or a four-way pipe joint.

The roof is specifically a roof overall structure layer which is formed by combining a plurality of layer bodies, usually, the lowest layer is a reinforced concrete roof layer, the uppermost layer is a concrete protective layer, an isolation layer, an insulation layer, a waterproof layer and the like are arranged in the middle, and the top layer of the roof is the uppermost layer.

Receive the sleet influence, the roof is intake and is mostly amasss in the heat preservation, and heat preservation intraformational water has the liquid and also has the gaseous state, the utility model discloses roof drainage structure, the drainage is the water of getting rid of liquid water and gaseous state, the blast pipe of blast pipe for getting rid of gaseous state water, the blast pipe of row vapor promptly.

Liquid water in the roof heat-insulating layer can enter the pipeline through the through holes on the two sides of the arched pipe body, the tail end of the pipeline is provided with a water outlet, and the liquid water is discharged from the water outlet. Gaseous water in the heat-insulating layer can also enter the pipeline through the through holes on the two sides of the arched pipe body and then is discharged through the air outlet of the pipe joint and the exhaust pipe connected with the air outlet. The utility model provides a pipe joint, including two-way pipe joint, three-way pipe joint, four-way pipe joint, lie in with the difference of ordinary pipe joint that the joint cavity upside has the gas outlet, again exactly the joint cavity will with heterotypic drainage blast pipe configuration is corresponding, according to this, the utility model provides a shape and the structure of pipe joint can be made clear and definite.

The invention is further described with reference to the accompanying drawings and the detailed description.
