Description

Passive house window insulation node structure

technical field

The utility model belongs to the field of passive houses, in particular to a window insulation node of a passive house.

Background technique

With the country's rapid promotion of energy conservation and emission reduction and the rapid development of building energy conservation, it is imperative to design new buildings and existing buildings with external thermal insulation. However, the external wall insulation industry developed relatively late in China, and has about 20 years of engineering experience, so there are many defects and deficiencies in the design. In recent years, with the development of my country's building energy-saving industry and the improvement of building standard requirements, more new building situations have gradually entered people's lives.

As a kind of ultra-low energy buildings, passive houses are gradually appearing before our eyes. In passive buildings, in addition to high thermal insulation and energy efficiency requirements, there are also high requirements for building air tightness. Since the doors and windows are installed by hanging, there are obvious gaps between them and the base wall, and there is a hidden danger of cracking and water leakage. Rainwater infiltrates into the insulation layer along the gaps, which can easily cause the outer wall to crack, burst and fall off, which not only affects the appearance of the building, but also reduces the service life and thermal insulation effect of the outer wall insulation layer.

The gap between the passive house window and the base wall is sealed with waterproof rain cloth, and the inside and outside of the passive house window are pasted with waterproof and breathable rain cloth, and the window fixture is covered;

The graphite polystyrene board is a double-layer structure, which is the first layer of graphite polystyrene board and the second layer of graphite polystyrene board from inside to outside;

The second layer of graphite polystyrene board and the first layer of graphite polystyrene board are pasted and connected by 1/2 board seam;

The thickness of the first layer of graphite polystyrene board is the same as the thickness of the window frame of the passive house window;

The gaps between the first layer of graphite polystyrene board and the second layer of graphite polystyrene board are filled with polyurethane foam;

detailed description

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

As shown in the figure, the thermal insulation node structure of the window of the passive house includes the thermal insulation layer 12 and the passive house window 2 arranged around the flat window and connected with the base wall 1 by adhesive. The shape is suitable; the heat preservation layer 12 is successively composed of graphite polystyrene board, protective surface layer mortar 13, alkali-resistant glass fiber mesh cloth 14 and facing layer 15 from the inside to the outside; the design of the heat preservation layer 12 not only plays a very important role A good protection effect can achieve the purpose of higher energy saving requirements, and ensure the airtightness of the window part, which can better achieve the effect required by the passive house.

The passive house window 2 adopts external hanging installation, which avoids the thermal bridge that may be generated at the window sill. Has pre-pressed sealing tape.

The gap between the passive house window 2 and the base wall 1 is sealed with a waterproof rain cloth, and the inside and outside of the passive house window are pasted with waterproof and breathable rain cloth, and the window fixing parts are covered; the design of the air-proof rain cloth and the pre-pressed sealing tape can also ensure The airtightness of the whole building enables the fresh air system, heat pump system and other equipment to work effectively

Described graphite polystyrene board is a double-layer structure, and from inside to outside is the first layer of graphite polystyrene board 4 and the second layer of graphite polystyrene board 5; The benzene board 4 is pasted and connected by 1/2 board seams; the thickness of the first layer of graphite polystyrene board 4 is the same as that of the window frame of the passive house window 2, thus avoiding the need to pass through the first layer of benzene board 4 around the window of the passive house Cutting can be turned into construction; the board seam of the first layer of graphite polystyrene board 4 and the second layer of graphite polystyrene board 5 is filled with polyurethane foam 10 .

The window frame of the passive house window 2 is provided with door and window connection lines.
