Abstract

The invention belongs to the technical field of buildings, and discloses a door and window joint and a construction method thereof. The door and window joint comprises a door and window auxiliary frame, an outer wall, a heat preservation layer and a keel, wherein the heat preservation layer covers the outer side of the outer wall, so that heat preservation of the outer side surface of the outer wall at the door and window joint is realized; the keel is connected with the outer side of the outer wall; the edge of the door and window auxiliary frame is connected with the edge of the outer wall,and a first sealing piece is arranged in a first gap formed between the outer wall and the door and window auxiliary frame; a second sealing piece is arranged in a second gap formed between the door and window auxiliary frame and the heat preservation layer; and the outer side of the first sealing piece and the outer side of the second sealing piece are respectively sealed by sealant. Through sealing treatment of the first gap and the second gap, heat preservation and sealing of the gap at the joint of the outer wall and the door and window auxiliary frame are realized, so that the door and window joint has good sealing performance and heat preservation performance, and the waterproof, heat preservation, heat insulation and sound insulation functions of a house are effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of buildings, in particular to a door and window joint and a construction method thereof. Background technique [0002] Prefabricated buildings have begun to develop rapidly in my country in recent years. Following the pace of the country's modernization of the construction industry, steel-structured prefabricated buildings have gradually opened up the market and become a new star in the construction industry. The market has shifted from public buildings to residential buildings. [0003] Housing is oriented to thousands of small owners, and there are higher standards and more perceptual requirements for waterproofing, thermal insulation, sound insulation and comfort of buildings. Therefore, the exterior wall, door and window systems of steel structure prefabricated residences need to be systematically designed. Construction, to ensure the functional needs of the building. The door and window joints in the ...
