Door window

Abstract

The invention provides a door window. The door window comprises a window frame assembly, at last one window sash assembly and a glass assembly, wherein at least one first hollowed-out structure and atleast one second hollowed-out structure are formed on the window frame assembly, the first hollowed-out structures are used for lighting, and the second hollowed-out structures are used for air circulation; the window sash assemblies are cooperatively connected with the second hollowed-out structures, can be opened or slide relative to the window frame assembly, and a third hollowed-out structurefor lighting is formed on each window sash assembly; the glass assembly is used for sealing the first hollowed-out structures and the third hollowed-out structures; and the window frame assembly comprises a plurality of border profiles, each window sash assembly also comprises a plurality of border profiles, and at least part of the border profiles are composite profiles prepared from non-metal plates and metal profiles. The door window has good heat preservation performance and sound insulation performance, and building energy consumption can be reduced.

Description

technical field [0001] The invention relates to the technical field of doors and windows, in particular to a door and window. Background technique [0002] The envelope of a building is composed of exterior walls, roofs, doors and windows, and the windows, which account for 20%-30% of the building area, are the parts that dissipate the most heat and can be said to be the weak link in the envelope. Door and window energy consumption control is the key to improving building energy efficiency. [0003] Aluminum alloy profiles are mostly hollow structures with light specific gravity. The material is 70 times lighter than bricks of the same volume, and the weight is only 1 / 3 of stainless steel. Aluminum profiles have the characteristics of short production cycle, excellent mechanical properties, and good processing performance. Moreover, because aluminum profiles can be bent arbitrarily or formed at one time, and have high processing precision, they can complete the production o...

Problems solved by technology

[0004] In the prior art, an aluminum-wood composite window structure is that the aluminum alloy main frame is an independent component, which bears the structural strength of the door and window. The aluminum frame and the wooden frame are made separately, and finally connected by nylon buckles or plastic bridges. The gap between them is prone to condensation, which is not good for wood protection

Another kind of aluminum-wood composite door and window is that the finished window is made of aluminum alloy profiles on the outside, and wooden profiles on the inside. The wooden profiles on the inside bear the structural strength of the doors and windows, and the aluminum alloy profiles are set on the outside of the wood profiles for waterproof, dustproof, and UV protection; Wood profiles also have heat preservation, humidity control and high decorative effects; but the processing of this wood profile is more complicated, and the quality requirements for wood materials are higher

[0005] Secondly, the bonding degree of composite materials (especially metal and wood composites) is not high, so cracking and degumming will occur when adhesives are used for bonding. Currently, there is no specific adhesive for metal and wood composite materials on the market. Most adhesives have average adhesion, short service life and contain harmful substances that will cause environmental pollution

For example, the publication date is July 8, 2015, and the Chinese patent with the publication number CN103773284B discloses a weather-resistant water-based adhesive and its preparation method. wood composites

[0006] In addition, the aluminum-wood composite materials obtained by the adhesives and processes of the prior art can only be used for interior decoration of rooms, such as sliding doors in kitchens and bathrooms, and cannot be used for external doors and windows, because the temperature difference between the inside and outside of external doors and windows is large, and the aluminum-wood composite The material is easy to warp, deform and crack, and the outside is exposed to the sun and rain, the adhesive is easy to age, and the aluminum-wood composite material is easy to crack
