[0023] Example: See Figure 1 , 3As shown in the figure, a hidden frame connection structure for a U-shaped glass curtain wall includes a door and window frame arranged inside the curtain wall. An aluminum alloy floor spring door 40 or a glass window 50 is arranged inside the door and window frame. The door and window frame is divided into a door frame or a window frame, but both include vertical side frames 10 and horizontal side frames 30. Among them, the horizontal side frame 30 of the door frame is different from the horizontal side frame 30 of the window frame, but the structures of the vertical side frames 10 of both are the same. U-shaped glass curtain walls 20 are arranged on both sides of the vertical side frame 10. The U-shaped glass curtain wall 20 is composed of a number of U-shaped glasses 21 that are opposite and misaligned and connected together; the vertical side frame 10 includes a vertical square pipe 11. On the outer walls of the rear side and the inner side of the vertical square pipe 11, an L-shaped stainless steel plate 12 is welded and fixed. At the rear end of the stainless steel plate 12, an L-shaped rear connecting edge 121 is bent and formed. At the end of the rear connecting edge 121, a lining plate 13 is welded and fixed. The lining plate 13 is welded and fixed on the outer wall of the outside of the vertical square pipe 11; on the outer wall of the front side of the vertical square pipe 11, a first steel groove 14 is welded and fixed. The side wall of the first steel groove 14 is welded and fixed on the side wall of the stainless steel plate 12. At the front end of the stainless steel plate 12, a front connecting edge 122 with a "匚" - shaped horizontal cross-section is formed.

[0024] One side of the U-shaped glass curtain wall 20 is inserted between the rear connecting edge 121 and the front connecting edge 122 of the stainless steel plate 12. The U-shaped glasses 21 inside the U-shaped glass curtain wall 20 are fixedly connected to the rear connecting edge 121 and the front connecting edge 122 respectively through first double-sided adhesive strips 16; a first rubber pad 15 is clamped and fixed between the end of the U-shaped glass 21 and the bottom surface of the first steel groove 14.

[0025] Figure 2 、 4 As shown in the figure, the door and window frame around the aluminum alloy floor spring door 40 is composed of two groups of left and right vertical side frames 10 and a horizontal side frame 30 arranged above the aluminum alloy floor spring door 40;

[0026] The door and window frame around the glass window 50 is composed of two groups of left and right vertical side frames 10 and two groups of upper and lower horizontal side frames 30. There is no need for a horizontal side frame 30 below the aluminum alloy floor spring door 40.

[0027] The described horizontal frame 30 includes a frame beam 31 with a "ㄇ" - shaped longitudinal section. The left and right ends of the frame beam 31 extend beyond the two ends of the door and window frame and abut against the upper or lower end of the U - shaped glass curtain wall 20 and are fixedly connected to the U - shaped glass curtain wall 20. Longitudinal sections of the front and rear ends of the frame beam 31 are respectively formed with connecting grooves 311 with a "凵" - shaped cross - section. Vertical curtain wall glasses 70 are respectively inserted into the connecting grooves 311. A second rubber pad 33 is clamped and fixed between the curtain wall glass 70 and the bottom surface of the connecting groove 311. A second double - sided adhesive strip 34 is fixedly connected between the curtain wall glass 70 in the connecting groove 311 and the inner side wall of the connecting groove 311. A number of vertical support square tubes 60 are provided between the curtain wall glasses 70, and the ends of the support square tubes 60 are welded and fixed to the frame beam 31. An inner groove frame 32 is provided between the frame beam 31 and the aluminum alloy floor spring door 40 or the glass window 50. Connecting edges 321 are respectively formed on the front and rear sides of the inner groove frame 32, and the connecting edges 321 are respectively fixedly connected to the connecting grooves 311 at the front and rear ends of the frame beam 31. Its frame beam 31 not only participates in the structure of the door and window frame but also serves as a support connecting member for other curtain wall glasses 70.

[0028] As Figure 4 shown, the horizontal frame 30 on the glass window 50 includes a horizontal first transverse square tube 35. The first transverse square tube 35 is inserted into the inner groove frame 32 and is welded and fixed to the inner groove frame 32. A horizontal second channel steel 36 is welded and fixed to the front side wall of the first transverse square tube 35. The connecting edge 321 on the front side of the inner groove frame 32 is inserted and fixed into the second channel steel 36. A C - shaped channel steel 37 is inserted and fixed between the second channel steel 36 and the connecting groove 311 on the front side of the frame beam 31. The first transverse square tube 35 is welded and fixed to the frame beam 31. The upper and lower ends of the glass window 50 are respectively inserted into the second channel steel 36. The glass window 50 is a fixed type. It is required to set the same slot positions on the horizontal frame 30, so the connecting edge 321 on the front side of the inner groove frame 32 is adjusted, and the second channel steel 36 and the C - shaped channel steel 37 are added for connection. At the same time, the main support member of its horizontal frame 30 is the first transverse square tube 35, and the first transverse square tube 35 is also hidden in the structure composed of the frame beam 31, the inner groove frame 32, the second channel steel 36 and the C - shaped channel steel <del>37< / del>.

The frame beam 31 is welded and fixed to the second transverse square tube 38 and the angle iron 39. The second transverse square tube 38 is welded and fixed to the inner groove frame 32. The main support members of its horizontal frame 30 are the second transverse square tube 38 and the angle iron 39. Similarly, the second transverse square tube 38 and the angle iron 39 are hidden in the structure composed of the frame beam 31 and the inner groove frame 32.

[0030] It should be noted that in the translation of the text in item , there is an extra "<del>37< / del>" in the original text, which seems to be an error in the original. I have translated it as it is in the translation. If this is not what you intended, please check and correct the original text.The aluminum alloy floor spring door 40 is provided with a guide rail above it. The guide rail abuts against the inner groove frame 32. Several screws are inserted into the guide rail. The screws pass through the inner groove frame 32 and are screwed to the second horizontal square tube 38.

[0031] The joint between the U-shaped glass 21 and the front connecting edge 122 and the rear connecting edge 121 is coated with a first structural sealant 17; the joint between the curtain wall glass 70 and the connecting groove 311 is coated with a second structural sealant 310. Both the first structural sealant 17 and the second structural sealant 310 can improve the sealing and waterproofing effect.

[0032] Polycarbonate sheets 80 are fixedly connected to the inner surface of the U-shaped glass 21 and the inner surface of the curtain wall glass 70, respectively; adding polycarbonate sheets 80 to the inside of the glass can significantly improve safety, comfort and energy efficiency.

[0033] Weather-resistant sealant 22 is applied to the joints between adjacent U-shaped glass curtain walls 20.

[0034] Working Principle: This structure is a U-shaped glass curtain wall with concealed frame connection. Its main technical point is the adjustment of the original square tube design on the exterior of the U-shaped glass curtain wall. The square tubes include vertical square tubes 11, first horizontal square tubes 35, second horizontal square tubes 38, and supporting square tubes 60, all of which are made into concealed frame structures. The specific structure is mainly designed and adjusted in conjunction with the structure of the door and window frames. For example, the vertical square tubes 11 are placed inside the vertical frame edges 10 on both sides of the door and window frames. The vertical frame edges 10 are placed on both sides of the aluminum alloy floor spring door 40 or glass window 50. The side, that is, between the U-shaped glass curtain wall 20 and the aluminum alloy floor spring door 40 or between the U-shaped glass curtain wall 20 and the glass window 50, instead of being set on the facade, achieves a simple and harmonious appearance. Moreover, the vertical square tube 11 is set inside the vertical frame 10 compared to the outside of the vertical frame 10 (the vertical square tube 11 set inside the vertical frame 10 has more welding points with the outer layer structure of the vertical frame 10), which can effectively improve the supporting strength of the vertical frame 10, thereby improving the stability and reliability of the U-shaped glass curtain wall 20 on both sides of the door and window frame.

[0035] In addition to setting the vertical square tube 11 inside the vertical frame 10, depending on the structure of the aluminum alloy floor spring door 40 or the glass window 50, the first horizontal square tube 35 or the second horizontal square tube 38 are respectively set inside the horizontal frame 30. At the same time, the horizontal frame 30 is also designed with a frame beam 31 to support the upper and lower inner and outer double-layer glass curtain walls (i.e., curtain wall glass 70). The frame beam 31 provides a supporting foundation for both the double-layer glass curtain wall and the U-shaped glass curtain wall 20, and also provides a supporting foundation for the supporting square tube 60 set between the curtain wall glass 70.

[0036] The embodiments described above are illustrative of the present invention and are not intended to limit the present invention. Any person skilled in the art can modify the embodiments without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be as set forth in the claims.
