As shown in fig. 1 and 2, a wind brace mounting structure of a curtain wall opening sash comprises: the window comprises a window frame 1, a fan frame 2 and a wind brace 3, wherein the wind brace 3 is connected between the window frame 1 and the fan frame 2; the wind bracing frame is characterized in that a thickened connecting part 2-1 protruding towards the side where the wind bracing 3 is located is arranged on the fan frame 2, and the wind bracing 3 is connected with the thickened connecting part 2-1 through a first screw 4; the thickened connecting part 2-1 is formed by integrally bending the section bar of the fan frame 2, so that a groove 2-2 corresponding to the thickened connecting part 2-1 is formed in the fan frame 2.

The thickened connecting part 2-1 means that the thickness of the section bar wall at the thickened connecting part 2-1 is larger than that of the section bar wall at other parts of the fan frame 2. The first screw 4 and the fan frame 2 can have higher connection strength by arranging the thickening connection part 2-1, so that the looseness of the first screw caused by wind pressure vibration is effectively reduced, and the safety performance of opening the fan is improved.

In this embodiment, the thickness of the profile at the thickened connecting portion 2-1 is preferably 1.5 times or more the thickness of the profile at other portions of the sash frame 2. For example, the thickness of the section bar wall at other parts of the fan frame 2 is 1.2mm, and the thickness of the section bar wall at the thickening connecting part 2-1 is 2 mm. Obviously, those skilled in the art can appropriately adjust the wall thickness of the thickened connecting portion 2-1 according to different actual needs, as long as the material consumption and the connection strength are considered, and the method is not limited to this embodiment.

It should be noted that, according to the wind brace installation structure of the curtain wall opening fan provided by the embodiment, by arranging the protruding thickened connecting portion 2-1 and the groove 2-2, during installation, only one end of the wind brace 3 is connected to the fan frame 2 by the first screw 4, and various gaskets such as additional pre-stressed screw pads and the like are not required to be arranged, so that the structure is simple and the installation is convenient; moreover, after the first screw 4 passes through the thickened connecting part 2-1, the first screw is hidden in the groove 2-2 and does not enter the corner brace installation cavity 2-3 of the fan frame 2; the inserting connection of the fan frame corner connectors cannot be affected.

In this embodiment, the wind brace 3 and the window frame 1 are fixedly connected through a second screw 5. Preferably, a plurality of support legs 7 are arranged on one side of the window frame 1 connected with the upright post 6, the window frame 1 and the upright post 6 are suspended through the support legs 7, and the second screw 5 penetrates through the window frame 1 and penetrates out of the suspended area. Like this, can effectively ensure the joint strength between wind brace 3 and the window frame 1 to it is not hard up to effectively reduce the second screw that the wind pressure vibrations lead to.

As an alternative embodiment, it is also possible to provide the window frame 1 with a thickened side at the side where it is connected to the second screw 5; for example, increasing the thickness of the window frame 1 at the side connected to the second screw 5 to 1.5 times or more the thickness at other positions also has the effect of increasing the connection strength between the wind brace 3 and the window frame 1, and is not limited to the present embodiment.

As another alternative, the joint between the window frame and the second screw may be a thickened part, and a protrusion protruding towards the inner cavity of the window frame is arranged on the thickened part; the effect of enhancing the connection strength between the wind brace and the window frame can also be achieved, and the wind brace is not limited to the embodiment.

It will be appreciated by those skilled in the art from the foregoing description of construction and principles that the utility model is not limited to the specific embodiments described above, and that modifications and substitutions based on the teachings of the art may be made without departing from the scope of the utility model as defined by the appended claims and their equivalents. The details not described in the detailed description are prior art or common general knowledge.
