[0025] The protrusion 3 is provided with a pressing plate 5 fixed to the protrusion 3 by a bolt assembly 4. The pressing plate 5 is provided with a through hole for the bolt 41 to pass through. The edge of the glass curtain wall panel 1 is arranged between the pressing plate 5, the protrusion 3 and the column body 2.

[0026] A first movable bar 6 is provided between the protrusion 3 and the pressure plate 5. The first movable bar 6 is provided with at least one first mounting hole 61, and the first mounting hole 61 is connected to the first through slot 31. The bolt assembly 4 includes a bolt 41 and a nut 42.

[0027] A filling material 11 is provided between the glass curtain wall panel 1 and the protrusion 3 and / or the first movable strip 6. That is, the filling material 11 can be filled to the protrusion 3 or only to the first movable strip 6, which can be done according to actual conditions.

[0028] During installation, the head of the bolt 41 is inserted into the first through groove 31, and the rod of the bolt 41 extends between the extension arms 32 and passes through the first mounting hole 61 and the through hole of the pressing plate 5, and is then threadedly connected with the nut 42, thereby pressing and fixing the glass curtain wall panel 1. After the pressing plate 5 is installed, the glass curtain wall panel 1 is inserted between the pressing plate 5, the column body 2, the protrusion 3, and the first movable bar 6, and then the bolt assembly 4 is tightened to complete the installation.

[0029] Of course, the present invention can also remove the first connecting strip 6, so as to be applicable to glass curtain wall panels 1 with lower thickness.

[0030] like Figure 1 、 Figure 3 and Figure 4 As shown, the first movable strip 6 is provided with a first step surface 62 on the side surface opposite to the protrusion 3, and a first groove 33 adapted to the first step surface 62 is provided on the side surface opposite to the protrusion 3 and the first movable strip 6.

[0031] like Figure 3 and Figure 4 As shown, a second groove 63 is provided on the surface of the first movable bar 6 on the side opposite to the pressing plate 5 .

[0032] like Figure 1 、 Figure 3 and Figure 4 As shown, first plug-in columns 64 are arranged at intervals on the first step surface 62, and the diameter of the first plug-in columns 64 is equal to the distance between the extension arms 32; a third groove 65 is provided in the second groove 63 corresponding to the position of the first plug-in columns 64, which can make the installation more accurate and simple.

[0033] like Figure 1 、 Figure 3 and Figure 4As shown, a second mounting hole 66 is provided at the bottom of the third groove 65, and the second mounting hole 66 passes through the first plug-in column 64. A rotating shaft 7 that can rotate in the second mounting hole 66 is provided in the second mounting hole 66. The rotating shaft 7 is located at one end of the third groove 65 and is provided with a rotating shaft cap 71. A straight groove 72 is provided on the end surface of the rotating shaft cap 71 away from the rotating shaft 7. A rectangular turning bar 73 is provided at one end of the rotating shaft 7 extending out of the first plug-in column 64. The middle part of the turning bar 73 is connected and fixed to the rotating shaft 7. When the rotating shaft 7 is rotated, the two sides of the turning bar 73 abut against each other with the extension arm 32 ( Figure 4 As shown), the connection between the first movable bar 6 and the protrusion 3 is tighter; the rotation of the rotating shaft 7 can be achieved by inserting a flat-blade screwdriver into the flat-blade slot 72, and rotating the flat-blade screwdriver to rotate the rotating shaft 7 together; in the present invention, the rotating bar 73, the rotating shaft 7 and the rotating shaft cap 71 are an integrally formed structure.

The fourth groove 83 is adapted to the second step surface 81, so that when the two second movable bars 8 are connected to each other, the second step surface 81 of one second movable bar 8 can just be inserted into the fourth groove 83 of the other second movable bar 8, thereby playing a limiting role; when there is only one second movable bar 8, the second plug-in column 82 is inserted into the third groove 65 to further limit the second movable bar 8; when there are multiple second movable bars 8, the two adjacent second movable bars 8 can be further limited by inserting the second plug-in column 82 into the fifth groove 84.

[0036] like Figure 7As shown, when the second movable bar 8 is connected to the first movable bar 6, the second plug-in column 82 is inserted into the third groove 65, and the second step surface 81 is placed in the second groove 63. At this time, the third mounting hole 85 is connected to the first mounting hole 61 at the corresponding position.

[0037] like Figure 1 As shown, a buckle cover 9 is provided on the pressure plate 5, and the buckle cover 9 and the pressure plate 5 are clamped and fixed to each other. Specifically, the pressure plate 5 is provided with first teeth 51 on both sides of the glass curtain wall panel 1, and the buckle cover 9 is provided with second teeth 91 that bite into the first teeth 51 at the position corresponding to the position of the first teeth 51.

[0038] like Figure 1 As shown, in order to ensure sealing, a first card groove 52 is provided on the surface of the pressure plate 5 opposite to the protrusion 3 and corresponding to the position of the glass curtain wall panel 1, and a second card groove 21 is provided on the surface of the column body 2 on the side of the protrusion 3 and corresponding to the position of the glass curtain wall panel 1. The first card groove 52 and the second card groove 21 are arranged along the length direction of the column body 2. A sealing strip 10 is clamped in the first card groove 52 and the second card groove 21. The side of the sealing strip 10 away from the first card groove 52 and the side of the sealing strip 10 away from the second card groove 21 are in contact with the glass curtain wall panel 1 respectively.

[0039] The present invention adopts a method of arranging a protrusion on the column body, a first through groove on the protrusion, and adding a first movable strip between the protrusion and the pressure plate, thereby achieving adaptation to at least two thicknesses of glass curtain wall panels. By adding a second movable strip, the glass curtain wall panels of a third thickness can be used. Not only is the structure simple and the construction is convenient, but modular production is also achieved, saving costs.
