Description

Technical Field

[0001] The utility model relates to the technical field of building material decoration products, in particular to a passive system door. Background Art

[0002] With the increase in the amount of urban construction, the urban heat island effect has become more and more serious. The urban heat island has increased the temperature of the entire city, causing a further increase in air conditioning energy consumption, while passive low-energy buildings will not produce the heat island effect. If many ordinary buildings that produce the heat island effect are transformed into low-energy buildings, the heat island will be eliminated one by one.

[0003] In order to better reduce energy consumption and reduce the harm caused by the heat island effect, Germany proposed the concept of "passive house" in the 1980s based on low-energy buildings. "Passive house" is a building that achieves constant temperature, humidity, oxygen, cleanliness and quietness in all four seasons through thermal insulation of the ground, walls, doors and windows, fresh air system and renewable energy such as solar energy and geothermal energy. Compared with traditional buildings, passive buildings can save more than 90% of energy consumption.

[0004] In the composition structure of a passive house, the door is a structure that is often opened and closed, and is also one of the channels for energy exchange between the inside and outside of the house. Its structure and installation method are very important for the formation of a passive house. At present, although most of the doors on the market have good sound insulation, fire prevention, and heat preservation effects, after actual testing, they still cannot meet the requirements of passive doors, and the currently disclosed prior art only describes the use effect of passive doors. For example, passive doors need to have ultra-low energy consumption building design, low thermal conductivity, high sealing level, to ensure the overall constant temperature performance, and at the same time have better sound insulation and anti-theft functions. However, no specific technical solutions have been disclosed, and the structure of passive doors needs to be developed. Utility Model Content

[0045] See also Figure 1 It can be seen that in this embodiment, a hinge 64 is installed in the third sound insulation and heat preservation chamber 15 located in the side frame 6, and a hinge decompression strip 16 is fixedly provided on the edge of the main frame shell 1, and one end of the hinge 64 extends to the outside of the third sound insulation and heat preservation chamber 15 and is fixed on the hinge decompression strip 16.

[0046] Here, the provision of the hinge pressure relief strip 16 can reduce the squeezing force of the hinge 64 on the door leaf during the process of opening and closing the door, and the noise of opening and closing the door is smaller.

[0047] Then, in this embodiment, both ends of the second sound insulation and heat preservation chamber 14 are respectively installed with heat-resistant isolation strips 65 .

[0048] See also Figure 1 In this embodiment, when the door is closed, in order to reduce wind resistance, the front panel 11 is flush with the front end of the door frame, and the rear panel 12 is flush with the rear end of the door frame.
