Problems solved by technology

[0007] In order to solve the existing ventilation pipes due to the roof leakage caused by the peeling of the waterproof material outside the waterproof casing, the water leakage point caused by the radial gap between the concrete roof panel, the waterproof casing, the ventilation riser and the waterproof filler caused by the temperature difference, due to the affected The vibration force and thermal expansion cause the ventilation riser and the waterproof filling material to separate from each other to form gaps and leaks. The embodiment of the present invention provides a roof extension ventilation pipe assembly and a method for preventing the ventilation riser from leaking.

Abstract

The invention discloses a vent-thru-roof (VTR) assembly on a roof and a method for preventing a vent stack from a water leakage, belonging to the field of building. The assembly is composed of a roof vent pipe seat, a sealing rubber ring, a waterproof cap, a sealing rubber mat, a roof vent pipe, a ventilation cap, a plurality of fastening bolts and a plurality of fixing bolts. In the invention, a waterproof cap is installed above on a roof vent pipe seat, so that a roof water leakage caused by the stripping of a waterproof material, water leakage points formed by radial gaps appearing on a concrete roof plate, a waterproof sleeve, a vent stack and a waterproof filling material caused by a temperature difference, and a gap water leakage formed by the mutual separation of the vent stack and the waterproof filling material caused by a shaking force and a thermal expansion can be efficiently prevented; and the VTR assembly on a roof is convenient to install.

Description

technical field [0001] The invention relates to the construction field, in particular to a roof extension ventilation pipe assembly and a method for preventing water leakage of the ventilation riser. Background technique [0002] With the rapid development of my country's construction market in recent years, people have higher and higher requirements for the quality of architectural design and construction. The roof extension vent pipe is a device used for ventilation and exhaust gas removal of the building drainage system. According to the existing building water supply and drainage design specifications, the building drainage system must be provided with a vent pipe that passes through the roof of the building. The current design and construction method is mainly to pre-fill the steel waterproof casing with concrete mortar and fix it in the roof slab layer, the ventilation riser passes through the steel waterproof casing to protrude from the roof, and then fills the steel ...
