[0020] The technical scheme of the utility model will be further specifically explained below by means of embodiments and in combination with the drawings.

[0021] As Figures 1 to 4 ​​As shown, a curtain wall corner connecting structure includes a stand column 3, a connecting piece 4, a glass glue strip 5 and an angle adjusting fixing piece 6. The connecting piece 4 is arranged in parallel on the outer side of the stand column 3. Two rotating grooves 7 extending in the vertical direction are arranged on the inner side of the connecting piece 4. The cross section of the rotating groove 7 is arc-shaped. The angle adjusting fixing piece 6 is arranged in the rotating groove 7. The angle adjusting fixing piece 6 can rotate around the axis of the rotating groove 7. The extrusion surface 8 is arranged on the inner side of the angle adjusting fixing piece 6. The glass glue strip 5 is arranged on the left and right sides of the stand column 3. The edge of the curtain wall 200 is arranged between the angle adjusting fixing piece 6 and the glass glue strip 5. The connecting structure further includes a mounting piece 9. The mounting piece 9 locks the connecting piece 4 on the stand column 3. The extrusion surface 8 of the angle adjusting fixing piece 6 presses the curtain wall on the glass glue strip 5.

[0022] Through the above arrangement, the angle adjusting fixing piece 6 can rotate to adapt to the installation of curtain walls with different included angles. The connecting piece 4 supports the outer side of the angle adjusting fixing piece 6, so that the angle adjusting fixing piece 6 is not easy to fall off, thereby improving the safety of the curtain wall.

[0023] The stand column 3 of the present application is vertically arranged at the corner of a building. The rotating groove 7 of the connecting piece 4 is arranged on the outer side of the stand column 3 with the groove opening inward. The upper and lower ends of the rotating groove 7 extend to the upper and lower sides of the connecting piece 4, respectively. The central angle corresponding to the cross section of the rotating groove 7 is less than 180 degrees, specifically 120 degrees, which facilitates the rotation of the angle adjusting fixing piece 6. The length of the angle adjusting fixing piece 6 is substantially equal to the length of the rotating groove 7. The upper end of the angle adjusting fixing piece 6 is flush with the upper end of the connecting piece 4, and the lower end of the angle adjusting fixing piece 6 is flush with the lower end of the connecting piece 4. The extrusion surface 8 of the angle adjusting fixing piece 6 is pressed on the outer side of the curtain wall by the mounting piece 9. The extrusion surface 8 is a plane, which ensures sufficient contact area between the extrusion surface 8 and the curtain wall, thereby improving the waterproof performance. The glass glue strip 5 is pressed on the inner side of the curtain wall, further improving the waterproof performance. The glass glue strip 5 and the extrusion surface 8 clamp the curtain wall, thereby fixing the curtain wall. The angle adjusting fixing piece 6 can rotate around the axis of the rotating groove 7, thereby automatically adapting to curtain walls with different included angles. At the same time, the connecting piece 4 supports the outer side of the angle adjusting fixing piece 6 through the rotating groove 7, which is more reliable than the traditional corner connecting structure. The angle adjusting fixing piece 6 is less likely to fall off, thereby improving the safety of the curtain wall.

[0024] As an implementation manner, the mounting piece 9 includes a threaded stud 91 and a nut 92. The threaded stud 91 penetrates the stand column 3 and is fixedly connected to the inner side of the connecting piece 4. The nut 92 is threadedly connected to the inner end of the threaded stud 91 and abuts against the inner side of the stand column 3.

[0025] Through the above arrangement, the connecting piece 4 is locked on the stand column 3 by the threaded stud 91 and the nut 92.

[0026] The angle adjusting fixing piece 6 of the application is provided with two, which are symmetrically arranged on the left and right sides of the stud 91, and the stud 91 is located on the angle bisector of the two curtain walls. The column 3 is provided with a bolt hole matched with the stud 91, and the stud 91 penetrates the column 3 through the bolt hole, and then a nut 92 is installed at the inner end. The nut 92 abuts against the inner side of the column 3, the stud 91 exerts a pulling force on the connecting piece 4, and the connecting piece 4 presses the angle adjusting fixing piece 6 against the outer side of the curtain wall.

[0027] As an implementation manner, the cross section of the angle adjusting fixing piece 6 is semicircular, the arc surface of the angle adjusting fixing piece 6 is attached to the rotating groove 7, the arc surface of the angle adjusting fixing piece 6 is fixedly connected with a guide strip 10 in the circumferential direction, and the rotating groove 7 is provided with a guide groove 11 in the circumferential direction.

[0028] Through the above arrangement, the angle adjusting fixing piece 6 is stably installed in the rotating groove 7.

[0029] The guide groove 11 of the application penetrates the opposite sides of the rotating groove 7 at both ends, which facilitates the insertion of the guide strip 10 into the guide groove 11. The guide strip 10 prevents the angle adjusting fixing piece 6 from moving up and down, and prevents the angle adjusting fixing piece 6 from being separated from the rotating groove 7, so that the angle adjusting fixing piece 6 can only rotate around the axis of the rotating groove 7.

[0030] As an implementation manner, the cross section of the guide strip 10 is T-shaped, and is matched with the cross section of the guide groove 11.

[0031] As an implementation manner, the extrusion surface 8 of the angle adjusting fixing piece 6 is provided with a first installation groove 12 extending in the vertical direction, and a sealing strip is installed in the first installation groove 12.

[0032] Through the above arrangement, the waterproofness between the extrusion surface 8 and the curtain wall is further increased.

[0033] As an implementation manner, the column 3 is provided as a square tube, the outer side corner of the column 3 is provided with a second installation groove 13 in the vertical direction, the cross section of the second installation groove 13 is T-shaped, the glass glue strip 5 is provided with a right-angled recess on the side away from the curtain wall, the outer side corner of the column 3 is embedded in the right-angled recess, the glass glue strip 5 is provided with a convex strip 14 matched with the second installation groove 13 in the right-angled recess, and the convex strip 14 is embedded in the second installation groove 13.

[0034] Through the above arrangement, the glass glue strip 5 is stably installed on the column 3.
