Embodiment 1

[0019] Such as figure 1 As shown, a rounded building ventilation and exhaust pipe of the present invention adopts a rectangular cavity pipe as the main body 1 of the exhaust pipe, and the junction 2 of its inner wall is an R arc transition chamfer, and the end surface is perpendicular to the outer wall of the main body of the pipe. Reinforcing ribs 3 are provided in the two sides of the exhaust pipe main body 1 and in the junctions 2 of the four inner walls. One side of the main body 1 of the exhaust pipe is provided with a reserved hole 4 for installing a fire check valve.

Embodiment 2

[0021] Such as figure 2 As shown, a rounded building ventilation and exhaust pipe of the present invention adopts a square cavity pipe as the main body 1 of the exhaust pipe, and the junction 2 of its inner wall is an R arc transition chamfer, and the end surface is perpendicular to the outer wall of the main body of the pipe. Reinforcing ribs 3 are provided in the junctions 2 of the four inner walls of the exhaust pipe main body 1 . One side of the main body 1 of the exhaust pipe is provided with a reserved hole 4 for installing a fire check valve.

[0022] This scheme improves the vertical pressure of the ventilation and exhaust pipes of the building, ensures the quality of the ventilation and exhaust of the building, and improves the working standard.

Abstract

The invention relates to a rounded building ventilation exhaust duct. The rounded building ventilation exhaust duct is characterized in that a duct body is a rectangular cavity duct; end faces of the duct body are perpendicular to the outer wall thereof; at least one of four edges of the duct body is internally provided with a reinforcing bar; at least one inner wall corner of the duct body is internally provided with a reinforcing bar; the combinations of any side and any inner wall corner of the duct body are internally provided with reinforcing bars, respectively. The rounded building ventilation exhaust duct has higher vertical compressive strength and has the advantages such as excellent strength, fire resistance, water resistance and light weight.

Description

technical field [0001] The invention relates to a ventilation and exhaust duct for buildings with rounded corners. Background technique [0002] Existing buildings, especially residential kitchens, toilets, and some ventilation and exhaust ducts in public areas, have technical problems such as low vertical pressure and low safety levels for residents. Contents of the invention [0003] In order to solve the above-mentioned existing shortcomings, the main purpose of the present invention is to provide a practical rounded building ventilation and exhaust duct, which improves the vertical pressure of the building ventilation and exhaust duct, and has excellent strength, fire prevention, waterproof, and light weight. Features. [0004] In order to achieve the above-mentioned purpose, a kind of rounded building ventilation and exhaust duct of the present invention adopts the following technical scheme: [0005] A ventilation and exhaust duct for a building with rounded corner...
