[0019] As Figures 1 - 5 shown, the anti-detachment device for building curtain walls includes a positioning frame 1. The positioning frame 1 is arranged in a C shape with one side open. It also includes a connecting rod 2 and a cross bar 3. The connecting rod 2 is movably connected to the outer side wall of the positioning frame 1. The adjusting rod moves horizontally and is adjusted by a horizontal adjustment mechanism 4 to fit the outer wall of the positioning frame 1. The cross bar 3 is movably connected to the bottom of the connecting rod 2. A vertical connection mechanism 5 is connected between the cross bar 3 and the connecting rod 2. The vertical connection mechanism 5 moves horizontally synchronously with the connecting rod 2 for adjustment. On the inner side wall of the positioning frame 1 near one side of the support plate 6, a baffle plate 17 is fixedly connected. On the side wall of the positioning frame 1 away from the support plate 6, a locking screw 18 is threadedly connected. The positioning frame 1 is on one side of the steel structure longitudinal beam and is horizontally sleeved on the outer wall of the longitudinal beam. By rotating the locking screw 18, the positioning of the device is achieved. When installing the curtain wall, through the action of the connecting rod 2 and the cross bar 3 at the lower part of the positioning frame 1 between the connected curtain walls, the horizontal adjustment mechanism 4 horizontally adjusts the left and right positions of the connecting rod 2 and the cross bar 3, and the vertical connection mechanism 5 adjusts the height of the cross bar 3, so that the adjacent curtain walls up and down, left and right are at equal intervals, and at the same time, the edges of the curtain walls are pressed, supported and limited.

[0020] As Figure 1 shown, in order to keep a certain distance between the adjacent curtain walls on the left and right, through the horizontal movement of the connecting rod 2 and the cross bar 3, the un-fixed curtain wall is horizontally pushed laterally to increase its lateral support and prevent the curtain wall from shifting laterally. The horizontal adjustment mechanism 4 includes a support plate 6, a stud 7 and an adjustment plate 8. The support plate 6 is fixedly connected to the side wall of the positioning frame 1 adjacent to the opening. The support plates 6 are symmetrically distributed.

The stud 7 is threadedly connected to the connecting rod 2. The stud 7 is rotatably connected inside the symmetric support plates 6. The adjustment plate 8 is fixedly connected to both end faces of the stud 7. By rotating the adjustment plate 8, the stud 7 rotates between the symmetric support plates 6, driving the connecting rod 2 to move horizontally. The connecting rod 2 is in contact with the positioning frame 1, increasing the movement stability and preventing the connecting rod 2 from rotating.

[0021] As Figure 2 , Figure 3 and Figure 5As shown in the figure, in order to adjust the height of the cross bar 3, keep a certain distance between the upper and lower adjacent curtain walls, use the lower curtain wall to support the upper curtain wall, and be applicable to curtain walls of different sizes, a sliding cavity 9 is opened in the lower part of the connecting rod 2. The vertical connecting mechanism 5 is slidably arranged in the sliding cavity 9 and extends along the length direction of the connecting rod 2 at the bottom end of the connecting rod 2.

The supporting spring 12 is wound around the outer side wall of the connecting rod 2. The supporting spring 12 is located between the bottom wall of the limiting plate 11 and the inner bottom wall of the sliding cavity 9. The cross bar 3 is fixedly connected to the lower end surface of the sliding rod 10. The cross bar 3 is arranged in a C shape. After the left and right positions of the connecting rod 2 are adjusted, the cross bar 3 is pulled downward so that the cross bar 3 is clamped between the upper and lower adjacent curtain walls, the lower curtain wall is used to support the upper curtain wall, and the connecting rod 2 is used to limit the curtain wall, which is convenient for injecting structural adhesive and bolt connection at the connection between the curtain wall and the steel structure.

[0022] As Figures 1 - 3 shown in the figure, in order to press the edges of the upper and lower adjacent curtain walls, pressing components 13 are arranged on the upper and lower side walls of the cross bar 3 close to the opening side. The pressing components 13 include clamping plates 14, adjusting screws 15 and rubber pads 16. The clamping plates 14 are fixedly connected to the upper and lower side walls of the cross bar 3 close to the opening side. The clamping plates 14 are arranged symmetrically up and down. The adjusting screws 15 penetrate through the clamping plates 14 and are threadedly connected to the clamping plates 14. The rubber pads 16 are rotatably connected to the pressing ends of the adjusting screws 15. After the cross bar 3 is inserted between the upper and lower adjacent curtain walls, the cross bar 3 is clamped between the upper and lower adjacent curtain walls, and the adjusting screws 15 are rotated to make the rubber pads 16 fit and push the edges of the curtain walls to press the curtain walls.

[0023] During specific use, the operator horizontally sleeved the positioning frame 1 on the longitudinal beam of the steel structure, rotated the locking screw 18 to make the side of the positioning frame 1 close to the baffle 17 fit the longitudinal beam, and used the positioning frame 1 to limit and fix the device by the baffle 17. In the initial state, the connecting rod 2 is located on one side of the symmetrical support plates 6, keeping away from the side where the curtain wall is installed, and the cross bar 3 fits with the lower end of the connecting rod 2;

[0024] When installing the curtain wall, horizontally engage the curtain wall between adjacent longitudinal beams through profiles, pull down the cross bar 3 to make the upper wall of the cross bar 3 fit the bottom wall of the curtain wall to be installed, rotate the adjusting plate 8 to horizontally push the curtain wall with the connecting rod 2 to position the curtain wall left and right. The bottom wall of the curtain wall to be installed is supported by the cross bar 3 and the curtain wall installed below to maintain the distance between the upper and lower adjacent ones. Place the curtain wall on the cross bar 3. Finally, rotate the adjusting screw 15 to make the rubber pad 16 fit and push the edge of the curtain wall to press the curtain wall, realizing the positioning during the installation process of the curtain wall. Inject structural adhesive at the connection between the curtain wall and the steel structure, and realize the positioning installation of the curtain wall through bolt connection;
