Energy-conservation and thermal-insulation aluminum wooden door and window with ultralow energy consumption

Abstract

The invention discloses an energy-conservation and thermal-insulation aluminum wooden door and window with ultralow energy consumption. A frame comprises an outdoor frame metal profile and an indoor frame compound profile which comprises an indoor frame wooden profile and a frame graphite polystyrene foaming plate spliced and fixed to the outside of the indoor frame wooden profile; a sash frame comprises an outdoor sash metal profile and an indoor sash compound profile which comprises an indoor sash wooden profile and a sash graphite polystyrene foaming plate spliced and fixed to the outside of the indoor sash wooden profile; a mullion comprises an outdoor mullion metal profile and an indoor mullion compound profile which comprises an indoor mullion wooden profile and a mullion graphite polystyrene foaming plate spliced and fixed to the outside of the indoor mullion wooden profile; and a false mullion comprises an outdoor false mullion metal profile and an indoor false mullion compoundprofile which comprises an indoor false mullion wooden profile and a false mullion graphite polystyrene foaming plate spliced and fixed to the outside of the indoor false mullion wooden profile. According to the energy-conservation and thermal-insulation aluminum wooden door and window, the thermal-insulation performance is significantly improved on the premise that the air tightness, water tightness and sound insulation properties are not influenced, and the heat transfer coefficient k is smaller than or equal to 0.8.

Description

technical field [0001] The invention belongs to the field of building doors and windows, and relates to an energy-saving and heat-preserving aluminum-wood door and window with ultra-low energy consumption. Background technique [0002] At present, the aluminum-wood doors and windows used by people basically adopt the structure of outer aluminum and inner wood, and the heat-insulating bridge aluminum alloy profiles and solid wood are composited by mechanical methods. The surface of the aluminum profile on the outdoor side is sprayed with electrostatic powder or fluorocarbon, which can resist ultraviolet rays in the sun and various corrosions in nature; the wooden profiles on the indoor side are processed into various structural forms and treated with water-based paint, equipped with special hardware systems and Insulating glass retains the characteristics and functions of pure solid wood doors and windows and also takes care of the different properties of wood and metal shrin...

Problems solved by technology

The surface of the aluminum profile on the outdoor side is sprayed with electrostatic powder or fluorocarbon, which can resist ultraviolet rays in the sun and various corrosions in nature; the wooden profiles on the indoor side are processed into various structural forms and treated with water-based paint, equipped with special hardware systems and Hollow glass retains the characteristics and functions of pure solid wood doors and windows and also takes care of the different properties of wood and metal shrinkage coefficients. Wood profiles are beautiful and generous indoors, but the thermal insulation performance of wood is not good, resulting in energy loss
