Embodiment 1

[0019] Such as figure 1 As shown, a right-angle building ventilation exhaust duct of the present invention adopts a rectangular cavity duct as the exhaust duct main body 1, the inner wall junction 2 is at a right angle, and the end surface is perpendicular to the outer wall of the duct main body. Reinforcing ribs 3 are provided in the two sides of the main body 1 of the exhaust pipe and the junction 2 of the four inner walls. A fire check valve installation reserved hole 4 is provided on one side of the exhaust pipe main body 1.

Embodiment 2

[0021] Such as figure 2 As shown, a right-angle building ventilation exhaust duct of the present invention uses a square cavity tube as the exhaust duct main body 1, the inner wall junction 2 is a right angle, and the end surface is perpendicular to the outer wall of the duct main body. Reinforcing ribs 3 are provided in the junction 2 of the four inner walls of the exhaust duct main body 1. A fire check valve installation reserved hole 4 is provided on one side of the exhaust pipe main body 1.

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

Abstract

The invention relates to a right-angled building ventilation exhaust duct. The right-angled 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 of the duct body, at least one of four sides of the duct body is internally provided with a reinforcing bar, at least one of inner wall corners of the duct body is internally provided with a reinforcing bar, and the combinations of any side and any inner wall corner of the duct body are internally provided with reinforcing bars, respectively. The right-angled building ventilation exhaust duct has higher vertical compressive strength and has the advantages of high strength, fire resistance, water resistance, light weight and the like.

Description

Technical field [0001] The invention relates to a right-angle building ventilation exhaust duct. Background technique [0002] Existing buildings, especially residential kitchens, toilets and some of the products under the requirements of the standards for ventilation and exhaust ducts in public areas, have technical problems such as low vertical pressure and low household safety levels. Summary 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 right-angle building ventilation and exhaust duct, which improves the vertical compression of the building's ventilation and exhaust duct, has excellent strength, is fireproof, waterproof, light, etc. Features. [0004] In order to achieve the above-mentioned purpose, a right-angle building ventilation and exhaust duct of the present invention adopts the following technical solutions: [0005] A right-angle building ventilation and exhaust...
