Corner connector for casement window sash of aluminum alloy doors and windows

Abstract

The invention discloses a corner connector for a casement window sash of aluminum alloy doors and windows, wherein the connector is made of heat isolating material, and comprises a vertical connecting shaft, a horizontal connecting shaft, an outside waterproof strip, an inside waterproof strip, a frame internal waterproof strip, a vertical casement window sash, and a horizontal casement window sash; the joint of the vertical connecting shaft and the horizontal connecting shaft is provided with the outside waterproof strip, the inside waterproof strip, and the frame internal waterproof strip, and installed between the vertical casement window sash and the horizontal casement window sash. The corner connector has the advantages that the corner connector has inside and outside waterproof strips, and can effectively prevent water; for arranging the vertical and horizontal connecting shafts, the corner connector can effectively connect the frame body; the corner connector adopts the heat isolating material, thus the heat transfer performance of doors and windows is reduced; the corner connector is simple in operation, and easy to practice; the waterproof performance of the casement window sash of aluminum alloy doors and windows is improved, and the service life of doors and windows is prolonged.

Description

technical field [0001] The invention relates to a connecting piece of an aluminum alloy door and window of a building, and more specifically relates to a corner connecting piece used for a casement window frame of an aluminum alloy door and window. Background technique [0002] At present, in the decoration project of aluminum alloy doors and windows in buildings, the connection of the aluminum alloy door and window casement frames adopts aluminum corner codes. The profiles are connected at 45 degrees. Since there is a certain gap between the connected casement frame profiles or between the casement frame profiles and the aluminum corner code, although the waterproof treatment of the structural adhesive is performed, it is not easy to control during the installation process, resulting in It is easy to seep water during use. To sum up, there are certain limitations in the connection of aluminum alloy door and window casement frames with aluminum corner codes. Contents of t...
