Injected bridge-cutoff aluminum profile used for inswinging casement window

Abstract

The invention discloses an injected bridge-cutoff aluminum profile used for inswinging a casement window, which comprises a window frame, a casement and a mullion. The window frame consists of a frame inner cavity, a frame outer cavity, a frame clapboard and a frame connecting plate. One end of the frame clapboard is connected with the middle part of the inner wall of the frame inner cavity, and the other end is connected with the middle part of the inner wall of the frame outer cavity. The frame clapboard, the inner wall of the frame inner cavity at one side of the frame clapboard, and the inner wall of the frame outer cavity make up a frame adhesive injection cavity. The frame connecting plate and the outer wall of the frame outer cavity are on the same plane, one end of the frame connecting plate is integrally molded with the end part of the outer wall of the frame outer cavity to form a frame outer decorative face, and the other end of the frame connecting plate extends outwards. The aluminum profile has the advantages that the wall thickness design of the side wall of the adhesive injection cavity is reasonable; the aluminum profile saves material while the original airtightness, watertightness, sound and heat insulation performances and thermal insulation properties are guaranteed; the percentage of outturn is improved; the weight per meter is reduced; and the production cost is reduced.

Description

technical field [0001] The invention relates to a broken bridge aluminum profile, in particular to a perfusion broken bridge aluminum profile used for an inner casement window. Background technique [0002] The broken bridge aluminum window of the prior art adopts the domestic advanced perfusion heat insulation and three-layer sealing form, which is tightly closed, has excellent air-tight and water-tight performance, and has excellent thermal insulation performance; Heat, heat preservation, excellent function, remarkable energy-saving effect. However, the broken bridge aluminum window of the prior art also has the following defects: the side wall of the glue injection cavity is connected with the glue after the glue injection, and the wall thickness of the side wall of the glue injection cavity has little effect on its load-bearing, while the existing The wall thickness of the broken bridge aluminum window glue injection cavity is thick and wastes material, the yield is low...
