Aluminum alloy window frame sealing drainage structure

Abstract

The invention provides an aluminum alloy window frame sealing drainage structure. According to the structure, an inner frame and an outer frame are respectively connected to two sides of a connectingpiece, glass is arranged in a window frame, and a buckling strip is arranged between the inner frame and the inner side surface of the glass. The structure is characterized in that, an open hole is formed in the side edge of the outer frame on the inner side of an external extending edge of the outer frame, a groove is formed in the surface on the outer side of the outer frame below the open hole,and space among the glass, the side edge of the outer frame and the extending edge communicates with the outside through the open hole and the groove. According to the structure, since the side edgeof the outer frame is not directly exposed in the external environment, an open hole with a larger area can be formed in the side edge of the outer frame without causing the problem of backward flowing of external water, the outflowing speed of seeping water is higher, and in addition, an elastic block arranged below the glass can effectively block gaps at the outer frame, the connecting piece, the inner frame and the buckling strip, so the problems of inward leakage of external seeping water and outward leakage of internal seeping water are avoided.

Description

technical field [0001] The invention belongs to the technical field of improving the drainage structure of an aluminum alloy window, in particular to a sealing drainage structure of an aluminum alloy window frame. Background technique [0002] Aluminum alloy windows are commonly used structures in buildings. The structure of the window frame is as follows: image 3 Shown: including outer frame 15, inner frame 2 and connector 19, where the outer frame, connector and inner frame are connected to each other to form a single-layer or multi-layer glass 8, the extension edge 10 of the outer frame and the glass An outer sealing strip 9 is arranged between the outer surfaces, and an inner sealing strip 5 is arranged between the buckle 1 and the inner surface of the glass. Since the outer sealing strip is in an outdoor environment, after a long time of use, water seepage often occurs, especially in heavy rains, it is easy to seep a lot of water, and the water will accumulate on the o...

AI Technical Summary

Problems solved by technology

[0003] The above structure has the following problems: 1. When the window frame is used for a long time, there will be some slight deformations, and sometimes water will accumulate on the convex edge 17 on the side of the outer frame, and mildew, 2. There is a rigid support 27 between the above-mentioned flange and the protruding part 7 of the connector, as well as between the flange 20 of the inner frame and the glass bottom surface, since there are many gaps in this place, when the extension edge When the water seepage cannot be discharged in time, the accumulated water will flow along the above-mentioned gaps to the connecting parts and the inner frame, and mold and odor will also appear after the seepage is dried; 3. There is also the problem of water seepage at the inner sealing strip. When water flows downward, it will also remain in the inner frame and connecting parts, and there are also problems of mold and odor; 4. The lower end of the extension edge is open, and in stormy weather, the outside water may have the problem of backflow
