Opening built-in door and window structure for passive building external wall external thermal insulation system and mounting method of structure

Abstract

The invention discloses an opening built-in door and window structure for a passive building external wall external thermal insulation system. The opening built-in door and window structure comprises a door and window body positioned in a door and window opening, a window frame of the door and window body is divided into an upper frame, a lower frame, a left frame and a right frame, a waterproof breathable roofing underlayment is pasted on the periphery of one indoor side of the window frame, connectors are mounted at four rims, the door and window body is fixed to the door and window opening through the connectors, damp-proof thermal insulation cushion blocks are arranged at mounting positions of the connectors and the door and window opening, a waterproof breathable film is pasted on the periphery of the outer vertical surface of one outdoor side of the window frame, thermal insulation rubber strips are continuously pasted at lapping edges of the rims of the upper frame, the left frame and the right frame and an external thermal insulation layer, the lower frame is provided with a water drip, and a window sill is fixed below the water drip. The door and window structure is convenient to mount, low in construction technical difficulty, small in labor input, high in operability, rapid in construction, high in work efficiency and remarkable in economic benefit, and convex-concave joints between the door and window frame and the door and window opening are decreased.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a door and window structure with a built-in hole in a passive building external wall external thermal insulation system and an installation method thereof. Background technique [0002] Passive low-energy-consumption building technology is the most advanced new building energy-saving technology in the world. Among them, the installation of doors and windows is one of the core technologies of passive low-energy buildings. This technology has extremely strict and extremely fine process technical standards and construction quality requirements. Any flaws in the construction process will seriously reduce the energy-saving effect of the building. . At present, the installation of doors and windows in passive buildings mainly adopts the construction of external hanging type. The construction process has the following drawbacks: 1. The doors and windows are fixed by external hang...
