Novel heat insulation and sound insulation building door and window profile

Abstract

The invention provides a novel heat insulation and sound insulation building door and window profile which comprises an aluminum alloy fixing and supporting frame, a heat insulation layer and an interior trimming layer. The aluminum alloy fixing and supporting frame is positioned outdoors, an outer layer inner cavity is formed in an outer layer of the cross section of the aluminum alloy fixing and supporting frame, an inner layer inner cavity is formed in an inner layer of the cross section of the aluminum alloy fixing and supporting frame, the heat insulation layer is embedded into the inner layer inner cavity, the interior trimming layer is positioned indoors and provided with screws, the screws are connected with the heat insulation layer and the aluminum alloy fixing and supporting frame, dense needle-shaped projections are arranged on the inner wall of the inner layer inner cavity, the heat insulation layer is made of polyurethane, and the interior trimming layer is made of PVC (polyvinyl chloride) plastics. As the heat insulation layer is embedded into the inner layer inner cavity of the aluminum alloy fixing and supporting frame, the heat insulation and sound insulation effects of doors and windows are improved, and the overall strength of the profile is enhanced as compared with that of an original heat insulation profile. In addition, the cost can be reduced, the profile conforms to the energy-saving development trend of the doors and windows, and the production process is more beneficial to mass production owing to structural change.

Description

technical field [0001] The invention belongs to the technical field of building door and window profiles, and in particular relates to a novel heat-insulating and sound-insulating building door and window profile. Background technique [0002] In order to meet the energy-saving requirements of buildings and reduce the heat and cold loss of building doors and windows, the broken-bridge building profiles with energy-saving effects currently used in building doors and windows products adopt the method of disconnecting the middle part of the original aluminum profile section and dividing it into indoor and outdoor sections. Two parts, and then insert an engineering plastic sheet with low thermal conductivity in the middle of the two parts to form a whole. Although this form of building door and window profiles has a good energy-saving effect, it has complex processing and material integrity. Not strong, expensive and other shortcomings.
