As shown in fig. 1 to 5, the embodiment discloses a roof vent waterproof structure, which includes an exhaust pipe 2 disposed on a roof 1, a bottom layer large-surface waterproof member 3 is laid on a roof surface around the exhaust pipe 2, a first set of holes 301 is disposed on the bottom layer large-surface waterproof member 3, and the first set of holes 301 is disposed on the exhaust pipe 2. The bottom layer large-surface waterproof piece 3 plays a waterproof protection role on the roof surface around the exhaust pipe 2, and prevents rainwater from permeating into a building from cracks on the roof around the exhaust pipe 2.

Be provided with the waterproof piece of circumferential weld 4 in the top of the big waterproof piece of bottom 3, the waterproof piece of circumferential weld 4 is rectangular form, and the waterproof piece of circumferential weld 4 includes pipe shaft parcel section 401, is provided with a plurality of connecting strips 402 on the lower bottom border length direction of pipe shaft parcel section 401. When using circumferential weld waterproof part 4 to construct, shaft of pipe parcel section 401 is the annular parcel on blast pipe 2, and each connecting strip 402 is the radial attached top surface of connecting in bottom macrosurface waterproof part 3 of annular, and the gap between blast pipe 2 and the roof has effectually been sheltered from to circumferential weld waterproof part 4 like this.

In order to improve the leakproofness that connecting strip 402 and bottom large face waterproof part 3 are connected, install top layer reinforcing waterproof part 5 additional on the basis of circumferential weld waterproof part 4, seted up second cover on top layer reinforcing waterproof part 5 and established hole 501, the second cover is established the hole 501 cover and is established on body of pipe parcel section 401 to top layer reinforcing waterproof part 5 covers laminating behind the whole connecting strip 402 and connects in the top surface of bottom large face waterproof part 3.
