[0031] Specifically, in this embodiment, the direction close to the periphery of the building window wall is called the outer end, the direction away from the periphery of the building window wall is called the inner end, the direction outside the building wall is called the outer side, and the direction inside the building wall is called the inner side.

[0032] The glass 4 is double-layer hollow glass, the window frame 1 is a hollow aluminum alloy profile, a cantilever is provided on the front side of the window frame 1, and a U-shaped groove is provided on the cantilever, and a glass outer rubber strip 8 is provided in the U-shaped groove to press the outer glass 4, and is used in conjunction with the glass inner rubber strip 5 on the inner pressure strip 2 to press the front and rear sides of the double-layer glass 4. An elastic filler with a multi-groove structure is provided between the edge of the double-layer glass 4 and the window frame 1 to protect the glass 4 from rigid collision with the window frame 1 and to improve the thermal insulation and sound insulation performance.

[0033] During installation, the double-layer glass 4 is pushed in from the rear side to the front side of the window frame 1. After the outer glass 4 is in contact with the outer glass rubber strip 8, the inner pressure strip 2 is installed. After the inner pressure strip 2 is installed, it clamps the glass 4 together with the cantilever on the front side of the window frame 1 to prevent the glass 4 from falling off. Then the outer pressure strip 3 can be installed.

[0034] The inner bead 2 includes a connecting portion and a beading portion, the connecting portion is connected to the window frame 1, the beading portions are connected to the connecting portions to form an L-shaped structure, and the inner end front side of the beading portion is pressed on the surface of the glass 4 through the inner glass strip 5, thereby clamping the front and rear sides of the double-layer glass 4. The inner end rear side of the beading portion is detachably connected to the outer bead 3 for the final installation of the outer bead 3.

[0035] A sealing strip 6 is arranged between the front side of the outer end of the outer strip 3 and the rear side of the window frame 1, so as to prevent condensation or condensed water from flowing into the space between the outer strip 3 profile and the inner strip 2 profile, and accumulating inside the window frame 1, thereby reducing the negative situations of water dripping from the bay window and mildew on the wall. In addition, due to the seal between the outer strip 3 and the window frame 1, the sealing performance of the window is also improved, which helps to avoid movement and noise when subjected to force.

[0036] Example 2

[0037] like Figure 1-Figure 4 As shown, a cantilever 201 extends backward from the rear side of the inner end of the inner bead 2, and a notch 301 is provided at the front side of the inner end of the outer bead 3, and the cantilever 201 is inserted into the notch 301. A filling rubber strip 7 is provided between the cantilever 201 and the inner wall of the notch 301.

[0038] Specifically, the protrusion 202 on the cantilever 201 of the inner bead 2 and the protrusion 302 in the notch 301 of the outer bead 3 are respectively formed into a barb shape. After the cantilever 201 of the inner bead 2 is inserted into the notch 301 of the outer bead 3, the barb protrusions on both sides of the filling rubber strip 7 squeeze into the filling rubber strip 7 to form an anti-pullout effect, thereby realizing the connection between the outer bead 3 and the inner bead 2; of course, this anti-pullout effect is limited, it prevents the free separation between the outer bead 3 and the inner bead 2, but when a greater degree of external force is applied, the notch 301 of the outer bead 3 and the cantilever 201 of the inner bead 2 can still be pulled apart. In this way, the outer bead 3 of other styles can be replaced, for example, it can be made into an arc or various line shapes instead of a square shape as shown in the figure, further improving the indoor decorative effect.

[0039] During installation, the outer pressure strip 3 is assembled at the corners in the workshop, and the inner pressure strip 2 is installed separately up, down, left and right.
