Description

A middle sealing strip of a passive house door frame

technical field

The utility model belongs to residential doors and windows, in particular to a sealing strip in the middle of a door frame of a passive house.

Background technique

"Passive house" means "passive ultra-low energy building". The so-called "passive house" refers to the use of advanced energy-saving design concepts and construction technologies to optimize the building enclosure structure, greatly improve the building's thermal insulation, heat insulation and airtight performance, and through the high-efficiency heat (cold) of the fresh air system. The recovery unit recycles heat (cold) from indoor exhaust air, thereby significantly reducing the building's heating and cooling needs. On February 4, 2016, the National Development and Reform Commission and the Ministry of Housing and Urban-Rural Development issued the "Action Plan for Urban Adaptation to Climate Change", which clearly stated the adoption of "actively developing passive ultra-low energy consumption green buildings, and adopting high-efficiency and high-performance external wall insulation systems, doors and windows, and improve building airtightness" to achieve the goal of improving the ability of urban buildings to adapt to climate change. Residential doors and windows are the main channel for residential heat dissipation and air communication. "Passive house" puts forward very strict requirements on the structure and performance of doors and windows. The requirements for doors and windows in passive ultra-low energy buildings:

The maximum heat transfer coefficient of external doors and windows (U value in the installed state) ≤0.8 (W/m ² ·K).

Air tightness: Under the condition of indoor and outdoor positive and negative pressure difference of 50Pa, the average number of air changes per hour of the building is less than 0.6.

Therefore, reasonable door and window structure design has a decisive impact on the construction and application of "passive houses".

Usually, the broken bridge aluminum alloy casement door is provided with two layers of inner and outer sealing strips between the door frame and the door leaf, but such a structure often cannot meet the technical requirements of "passive house".

Contents of the invention

In order to achieve the above purpose, the technical solution of the utility model is a middle sealing strip of a passive house door frame, which is installed on the inner side of the door frame. The middle sealing strip of the door frame is a hollow sealing strip with a cavity, and the middle sealing strip of the door frame The inner side is provided with a door frame sealing butt joint edge protruding from the outer edge.

Furthermore, the sealing butt joint edge of the door frame corresponds to a cavity, and the door frame seal butt joint edge is provided with a corrugated inner wall.

Furthermore, the sealing strip in the middle of the door frame is provided with six cavities.

Furthermore, both sides of the sealed butt joint edge of the door frame are inclined side walls.

Furthermore, the outer surface of the middle sealing strip of the door frame is provided with two mounting clips for connecting with the door frame.

Furthermore, the middle sealing strip of the door frame is a EPDM sealing strip.

The beneficial effects of the utility model are: the middle sealing strip of the passive house door frame has good heat insulation and sealing performance, and is arranged between the door frame and the door leaf to realize a three-layer sealing structure between the door frame and the door leaf, which can meet the technical requirements of "passive house" Require.

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