Abstract

The utility model provides an integrated fire-resistant exhaust passage for kitchens and toilets. The fire-resistant exhaust passage adopts a pipeline structure with a hollow square-shaped section; the length L of the pipeline is 2500-3500 mm; the side length A or the side width B of the hollow square-shaped section is 250-800 mm; the thickness of the wall of the pipeline is 5-15 mm; and four internal angles of the cross section of the pipeline take the shape of a circular arc with a 45 degree chamfer angle or a right angle. The integrated fire-resistant exhaust passage can be directly mounted after being transported to a building site, so that the assembly process of a combined-type fire-resistant exhaust passage in the prior art conducted when the combined-type fire-resistant exhaust passage is transported to the building site is eliminated, that is, the integrated fire-resistant exhaust passage is not required to be assembled again after being transported to the building site. The integrated fire-resistant exhaust passage is suitable for industrial mass production; and the quality of products in a production line can be guaranteed.
