Next, an out-swinging window in the present exemplary embodiment will be further described.

In an embodiment of the present utility model, the middle parts of the main frame, the lower frame, the fixed frame and the rotating frame are all provided with broken bridges; wherein the broken bridge is a penetrating broken bridge.

The strip-penetrating type heat-insulating section is characterized in that heat-insulating strips are inserted into two groups of aluminum sections and then rolled into a broken bridge heat-insulating section, and the two heat-insulating strips are used for connecting the inner part and the outer part of the aluminum section, so that the conduction of heat inside and outside the aluminum section is prevented, and the purpose of energy conservation is realized. The most important part of the bridge-breaking process is the heat insulation strip in the bridge-breaking aluminum. The heat insulation strips are made of two materials at present, one is PA66 nylon heat insulation strip, the other is polyurethane glue injection, and most of the materials are cavity-free. Our country was introduced with European style, i.e. nylon heat insulation strips. The aluminum alloy profile is added with a material with poor heat conduction performance in the middle part of the aluminum alloy profile to conduct heat conduction blocking, so that the heat insulation effect is achieved. The bridge is a cold and hot bridge in architecture, the cold and hot can be quickly transmitted through metal, and the bridge is broken by using different materials to break the cold and hot, so as to block the heat circulation. In short, the traditional aluminum alloy doors and windows have the defects that the metal heat conduction is relatively fast, the indoor and outdoor temperature difference is relatively large, and the aluminum alloy forms a 'bridge' for heat transfer. The bridge-cut-off is to disconnect the aluminum alloy from the middle, and the aluminum alloy on two sides is connected by adopting a separator with low heat conductivity coefficient, so that heat is not easy to transfer, and the bridge-cut-off aluminum is called as bridge-cut-off aluminum.

In a specific embodiment, the main frame, the lower frame, the fixed frame and the rotating frame are all provided with broken bridges in the middle, so that the economic energy-saving effect is achieved, and the performance is guaranteed to be better.

It is to be noted that the broken bridge aluminum door and window is a door and window product with a frame and a fan structure manufactured by aluminum alloy building section bars. When the section bars are manufactured into the fan frame, a corner combining process is needed to splice the section bars. The corner combining process plays an important role in door and window stability, and different corner combining processes have different influences on door and window assembly modes and overall performances. The corner collision process is to smear the section glue on the surface of the aluminum alloy section, plug the corner connector into the section cut at 45 degrees, and connect the section by the impact extrusion of a precision machine, thus forming an integral molding, and being not easy to crack when water is fed in a seamless way. But because the collision angle is needed to be carried out during production, the field framing is not supported.

As an example, the window frame ratio of the out-swinging casement window of the present utility model ranges from 0.19 to 0.21, preferably may be 0.19, 0.20, 0.21, etc., wherein the window frame ratio refers to the ratio of the front projection area of the aluminum frame of the window to the projection area of the whole window, and the smaller the window frame ratio, the better the energy saving.
