Aluminum alloy door and window frame and hole wall gap for how much, in the specification can be found
The gap between the door frame and the hole is required
Wall facade material between the door and window frame and the hole between the gap
Water wall 15mm, mortar + coating 20 ~ 25mm. Bricks 25 ~ 30 mm.
Stone 40 ~ 50mm (using concrete mouth or increase the sub-box) outside the insulation wall
External insulation thickness + Facing material practice gap -10
Note:
(1) due to the finishes (including insulation) material thickness requirements, will make the window frame and the hole between the gap increases, when the door
When the gap between the window frame and the hole is greater than 35mm, it is necessary to add a concrete mouth or steel sub-frame between the door frame and the hole. The gap between the mouth and the window frame should not be greater than 20mm; sub-frame and the gap between the doors and windows frame is 5mm, sub-frame and the hole side of the gap should not be greater than 20mm; no sub-frame when the finish surface to be pressed window frame 5mm , There are sub-frame when the surface and sub-box top flush.
(2) The gap between the threshold of the door frame and the hole shall be adjusted according to the difference between the floor material and the threshold of the door frame.
To ensure that the gap between the threshold and the floor (wall) filled with dense and external waterproof integrity, after the completion of the floor of the floor should be high outside the low
Curtain wall, aluminum alloy doors and windows with building structural standards in Table 6.1.1
Look at the surface material, the general coating is 5mm enough, if it is stone, you need 20-30 or even larger.
