Passive door-leaf-concealing door

Abstract

The invention discloses a passive door-leaf-concealing door. Through arrangement of an external aluminum frame with heat insulation property, butt-joint gaps formed between the periphery of a door leaf and a door frame during door leaf closing are completely shielded and concealed, the door leaf concealing function is achieved, thus the integrity degree of the outer side of a building is improved,and the aesthetic property of the outer side of the building is increased. Through filling of a door cavity of the door leaf with a fire-resistant heat insulation material, arrangement of a heat insulation layer on the external aluminum frame, ladder-like arrangement of all connecting plates on the door leaf, and the sealing connecting effect of sealing rubber strips at all butt-joint positions,the heat transfer coefficient of the whole door can reach the using standard of a severe cold area, the heat insulation property is extremely good, and the passive door-leaf-concealing door with highpracticability is formed; and meanwhile, through arrangement of matching of the water-retaining sealing rubber strips with skew fillets on an external door plate, the property of resistance for wetting by rain of the whole door structure is improved, the problem that a rain cape cannot effectively shield rainwater for the bottom of the door leaf is solved, the service life of the door leaf is prolonged, the rainwater can be effectively prevented from leaking into an indoor space from a bottom gap between the door leaf and the door frame, and the practicability is extremely high.

Description

technical field [0001] The invention relates to the technical field of building doors and windows, in particular to a passive hidden leaf door. Background technique [0002] With the vigorous development of China's construction industry and the improvement of environmental protection awareness, residential and public buildings have higher and higher requirements for the technology, appearance and physical properties of doors and windows. The residential design specifications issued by the state have higher and higher requirements for the thermal insulation performance of doors and windows. Only those whose thermal insulation performance meets the requirements of passive houses can be called passive doors and windows, which plays a decisive role in energy conservation, emission reduction and energy conservation. At present, there are very few door products on the market that can achieve passive doors and windows, and the openable part of the existing door structure can see a ...

AI Technical Summary

Problems solved by technology

At present, there are very few door products on the market that can achieve passive doors and windows, and the openable part of the existing door structure can be seen from the outside as a circle frame, which does not have the effect of a hidden fan, resulting in a low integrity of the outside of the building , not only poor thermal insulation performance, but also very unsightly
