Waterproof joint structure and construction method of air duct exiting concrete structure opening

Abstract

The invention relates to a waterproof node structure of an air pipe concrete discharge structure cave entrance and a construction method of the waterproof node structure, wherein the waterproof node structure of the air pipe concrete discharge structure cave entrance comprises an air pipe, a cover plate, a flexible isolation layer, a protection layer and a flexible isolation rod, wherein the air pipe is arranged in the concrete structure in a penetrating way through a cave entrance formed in a concrete structure; the cover plate is fixedly arranged at the outer side of the cave entrance, and comprises a first sub plate and a second sub plate which are mutually connected; the first sub plate is attached to the concrete structure along the periphery of the air pipe; the second sub pipe is attached to the periphery of the air pipe along the trend of the air pipe; the flexible isolation layer is arranged between the first sub plate and the concrete structure in a clamped way and is arranged between the second sub plate and the air pipe in a clamped way; the protection layer is arranged on the outer surface of the concrete structure; an installing seam is reserved between the end part of the protection layer and the second sub plate; and the flexible isolation rod is arranged in the installing seam. The rigid waterproof measure is combined with the flexible waterproof measure, so that the reliable connection of the vibration air pipe and the concrete structure cave entrance is realized; the fixation is tight; and good water stop performance is achieved.

Description

Technical field [0001] The invention relates to the field of building construction, in particular to a waterproof node structure with a concrete structure opening through a wind pipe and a construction method thereof. Background technique [0002] With the development of the times, more and more roofing equipment appears in public projects such as conventional shopping malls and office buildings, which puts forward higher requirements for waterproof and leak-proof construction projects. The indoor air-conditioning duct exits through the horizontal opening of the roof concrete structure and is connected to the roof air-conditioning unit. The opening of the concrete structure of the wind pipe needs to be waterproofed to prevent rainwater from entering the room. [0003] Because the air duct is vibrating during operation, it is easy to damage the traditional rigid waterproof structure, resulting in unreliable connection between the air duct and the concrete structure opening, and the...
