An aluminum alloy casement window

Abstract

The invention discloses an aluminium alloy casement window which comprises a window frame, a window support and a window sash, wherein the window support is located between the window frame and the window sash, the window frame is provided with a line pressing groove, a stepping bar is arranged above the groove mouth of the line pressing groove, one end of the window support is fixed on the window frame through the stepping bar, and the other end of the window support is fixed on the window sash. According to the aluminium alloy casement window, due to the facts that the stepping bar is arranged above the groove mouth of the line pressing groove and one end of the window support can be fixed on the window frame through the stepping bar, the fact that milling machining is carried out on the line pressing groove is avoided, and the window support is enabled to be conveniently and rapidly installed on the window frame.

Description

technical field [0001] The invention relates to an aluminum alloy casement window. Background technique [0002] The window stay is used to lock the open state of the window sash after pushing the window sash away. Generally, one end of the window stay is fixed on the window frame, and the other end is fixed on the window sash. In the aluminum alloy casement window, the window stay is inconvenient to be fixed on the window frame due to the existence of the crimping groove on the window frame. In the prior art, the method of fixing the window brace on the window frame is to first remove a part of a rib forming the crimping groove, and then fix the window brace on the bottom of the crimping groove. Such as figure 1 As shown, it is the structure of a frame in the window frame of an aluminum alloy casement window. The frame is composed of an outdoor window frame profile 103, a broken bridge 102, and an indoor side window frame profile 101. The crimping groove of the frame is c...

Problems solved by technology

[0003] In the prior art, because the ribs on the window frame need to be milled, the length of the milling process needs to be adjusted according to the length of the window brace, which makes the processing inconvenient, and the milling is too much and it is not beautiful, and the milling is too short to install the window brace. Finally, the original crimping groove of the window frame was destroyed, and the installation of the window stay was very inconvenient

And in the prior art, the window brace is fixed in the crimping groove. When there is rainwater in the crimping groove, the window brace is soaked in rainwater, which is easy to corrode; because the window brace is fixed at the bottom of the crimping groove, the drainage of the window frame The effect is also greatly reduced; before milling, it is necessary to determine the side where the window stay is installed according to the opening direction of the sash. Milling is very troublesome in actual operation, prone to errors, and reduces production
