In order to achieve the purpose, the utility model adopts the following technical scheme:

the design is a building roof waterproof exhaust device, which comprises an exhaust pipe, wherein a roof layer is respectively formed by a structural layer, a leveling layer, a heat insulation layer, a waterproof layer and a protective layer from inside to outside, the exhaust pipe extends outwards from the roof layer in the roof layer, the inlet end of the exhaust pipe is inserted into the heat insulation layer, a plurality of exhaust holes are formed in the inlet end of the exhaust pipe, the exhaust holes are formed in the exhaust pipe along the circumference of the center of the exhaust pipe, the outer side of each exhaust hole is provided with a first exhaust groove and a second exhaust groove in a crossed manner on the heat insulation layer, and the first exhaust groove and the second exhaust groove are arranged in a perpendicular and crossed manner in the center of the exhaust pipe.

Preferably, the outlet end of the exhaust pipe is opened downwards.

Preferably, the protective sleeve is sleeved on the outer wall of the exhaust pipe on the protective layer, the lower end of the protective sleeve is tightly attached to the protective layer in a sealing mode, and concrete is filled in the space between the protective sleeve and the exhaust pipe.

Preferably, the barrier net is fixedly installed at the outlet end of the exhaust pipe.

The utility model provides a building roof waterproof exhaust device, which has the beneficial effects that: this waterproof exhaust apparatus of building roofing passes through the intraformational gas of first air discharge duct and the intraformational gas of second air discharge duct discharge heat preservation of seting up of heat preservation to in flowing into the blast pipe through the exhaust hole, the exit end through the blast pipe flows to the external world, reaches and prevents that the roofing from leading to the fracture destruction of roofing because of the frost heaving of water, gaseous pressure, the life's of extension roofing effect.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1-3, a building roof waterproof exhaust device comprises an exhaust pipe 6, a roof layer is respectively composed of a structural layer 1, a leveling layer 2, a heat preservation layer 3, a waterproof layer 4 and a protective layer 5 from inside to outside, the exhaust pipe 6 extends from the inside of the roof layer to the outside of the roof layer, an outlet end opening of the exhaust pipe 6 is downward, an inlet end of the exhaust pipe 6 is inserted into the heat preservation layer 3, the exhaust pipe 6 can discharge gas in the heat preservation layer 3 in time, the roof is effectively prevented from cracking and damage due to frost heaving of water and gas pressure, the service life of the roof is prolonged, the inlet end of the exhaust pipe 6 is provided with a plurality of exhaust holes 10, the exhaust holes 10 are uniformly distributed along the central circumference of the exhaust pipe 6, the exhaust holes 10 are used for gas circulation between the heat preservation layer 3 and the exhaust pipe 6, the heat preservation layer 3 outside the exhaust holes 10 is provided with a first exhaust groove 8 and a second exhaust groove 9 in a crossed manner, and the first exhaust groove 8 and the second exhaust groove 9 are vertically and crossly arranged along the center of the exhaust pipe 6, and the first exhaust groove 8 and the second exhaust groove 9 are both used for exhausting the gas in the heat-insulating layer 3.
