Embodiment 1

[0072] Such as Figure 1-8 As shown, a prefabricated passive house exterior wall with doors and windows installed includes a rectangular sheet-shaped wall with door and window installation openings. The wall includes an inner wall 4 and an outer wall 6, and the inner wall 4 and the outer wall In the middle of the page wall 6, there is a thermal insulation board as the thermal insulation layer 5; the thermal insulation layer 5 is made of high-efficiency thermal insulation material GPES rigid foam composite plastic thermal insulation board with thermal conductivity ≤0.022w / (m·K) or polyurethane modified polyisocyanurate Rigid foam composite plastic insulation board; the insulation layer of the door and window installation opening is an L-shaped section structure. The outer side of the top of the door and window frame and the outer side of the left and right sides of the door and window frame are closely matched with the L-shaped section of the insulation layer. The horizontal part...

Embodiment 2

[0082] Such as Figure 9-11 As shown, a door and window connector includes a body 27 with a zigzag flap shape. On both sides of the body 27 there are symmetrically arranged raised bands 28 with an n-shaped cross section. A positioning is provided on the top of the raised band 28 at one end of the body 27. Protruding 8. The body 27 is provided with a through hole. The through hole is an oval hole. Such as Figure 12-14 As shown, the raised belt 28 is provided with an ear plate 29 extending outward, and the positioning protrusion 8 and the ear plate 29 are located at the same end of the body 27. A through hole is provided on the ear plate 29. The Z-shaped flap-shaped body 27 of the connecting piece has a height of 12mm, a width of 60mm, and a length of 200mm, and is made of 3mm steel plate.

Embodiment 3

[0083] Embodiment 3: A construction method for installing doors and windows on the exterior wall of a prefabricated passive house, which is characterized in that it includes the following steps:

[0084] (1) Make door and window openings and door and window frames according to the relationship between door and window opening size and door and window frame size:

[0085] Door and window opening width=(door and window width+2×a)±1mm

[0086] Door and window opening height = (door and window width + c+b) ± 1mm

[0087] a: the distance from the left outer side of the door and window frame to the left side of the door and window opening or the distance from the right outer side of the door and window frame to the right side of the door and window opening is 15±1mm; b: the distance from the lower outer side of the door and window frame to the bottom of the door and window opening is 35±1mm, of which the height dimension of the additional profile 21 of the window frame is 30±1mm; c: the dist...

Abstract

The invention discloses an assembly type passive house external wall provided with doors and windows, and a door and window installation method thereof. The external wall is characterized in that the external wall comprises rectangular sheet wall units provided with door and window installation holes, the wall units comprise an inner wall unit and an outer wall unit, and a heat-insulation sheet material serving as a heat-insulation layer is arranged between the inner and outer wall units. A door and window connector is characterized in that the connector comprises a Z-shaped bent sheet connector body, uplifted zones having n-shaped cross sections are symmetrically arranged on the two sides of the connector body, and the top portions of the uplifted zones at one end of the connector body are provided with positioning projections.

Description

Technical field [0001] The invention belongs to the technical field of building door and window construction, and relates to a connection structure between an external wall of an assembled passive house and doors and windows. In particular, it relates to door and window connectors, factory-produced passive house building exterior walls installed with passive house windows, and the method of installing doors and windows on the exterior wall of prefabricated passive house buildings. The doors and windows involved specifically refer to the high-efficiency insulation doors and windows above 70 series (door and window heat transfer Coefficient K≤1.0W / (㎡k)) installation. Background technique [0002] At present, in the installation of doors and windows in domestic buildings, firstly, the openings of the doors and windows are reserved by pouring concrete or masonry on site, and then the dimensions of the openings are measured, and the doors and windows are made according to the measured...
