[0017] Please see Figure 1 , Figure 1The diagram shown is a schematic structural diagram of a sealing device for a curtain wall expansion joint in one embodiment of the present invention. This sealing device is assembled into the expansion joint of the curtain wall and has the advantage of strong self-adaptability, which can effectively adapt to the current dynamic deformation requirements.
[0018] Specifically, in Figure 1 In the structure shown, the sealing device for curtain wall expansion joints in this embodiment includes a connecting assembly, a cover plate 20, and a sliding connecting rod 30. The connecting assembly includes a first connecting member 101 and a second connecting member 102. Both the first connecting member 101 and the second connecting member 102 are L-shaped structures and made of aluminum alloy. The connecting assembly is used to assemble in the expansion joint of the curtain wall. The first connecting member 101 is connected to the decorative surface on one side of the expansion joint by a first machine screw 111, and the second connecting member 102 is connected to the decorative surface on the other side of the expansion joint by a second machine screw 112, so as to fix the connecting assembly to the decorative surfaces on both sides of the expansion joint.
[0019] For example, in this embodiment, the decorative surfaces on both sides of the expansion joint are a first decorative surface 51 and a second decorative surface 52, respectively. The first decorative surface 51 is provided with a first aluminum alloy column 510, and the second decorative surface 52 is provided with a second aluminum alloy column 520. Both the first machine screw 111 and the second machine screw are screws with a diameter of 6 mm and a length of 20 mm. A plurality of first machine screws 111 are evenly distributed at 300 mm intervals along the length direction of the first aluminum alloy column 510 to connect the first connector 101 to the first aluminum alloy column 510; a plurality of second machine screws 112 are evenly distributed at 300 mm intervals along the length direction of the second aluminum alloy column 520 to connect the second connector 101 to the second aluminum alloy column 510.
[0020] The cover plate 20 adopts a U-shaped structure. A rotating shaft 201 is located at the center of its length on the inner side of the cover plate 20. The shaft is installed by creating a through hole in the cover plate 20, through which a screw 200 with a cap passes and threadedly connects to the rotating shaft 201, thus assembling the rotating shaft 201 onto the inner side of the cover plate 20. After the connecting assembly is installed into the expansion joint of the curtain wall, the cover plate 20 covers the expansion joint to seal it.
[0021] A rotating hole 300 is provided at the center of the sliding link 30 along its length, and a first elongated hole 31 and a second elongated hole 32 are provided at both ends, with the length directions of the first elongated hole 31 and the second elongated hole 32 both along the length direction of the sliding link 30. A rotating shaft 201 is assembled in the rotating hole 300 so that the rotating shaft 201 and the sliding link 30 form a rotatable structure, allowing the sliding link 30 to rotate around the rotating shaft 201. To ensure the reliability of the assembly, in this embodiment, a first stop 202 and a second stop 203 are respectively provided on the rotating shaft 201 at positions on both sides of the sliding link 30 to prevent the rotating shaft 201 from falling out of the rotating hole 300.
[0022] The first sliding bolt 301 passes through the first elongated hole 31 and is connected to the first connector 101, and the first sliding bolt 301 can slide along its length in the first elongated hole 31; the second sliding bolt 302 passes through the second elongated hole 32 and is connected to the second connector 102, and the second sliding bolt 302 can slide along its length in the second elongated hole 32.
[0023] The sealing device provided in this embodiment can be used if the distance between the decorative surfaces on both sides of the curtain wall expansion joint changes, such as Figure 3 As shown, if the distance between the first decorative surface 51 and the second decorative surface 52 changes, the first sliding bolt 301 can slide along its length in the first elongated hole 31, and the second sliding bolt 321 can slide along its length in the second elongated hole 32, so that the distance between the first connecting member 101 and the second connecting member 102 matches the distance between the decorative surfaces on both sides of the expansion joint. If the decorative surfaces on both sides of the curtain wall expansion joint undergo translational changes, that is, if the first decorative surface 51 and the second decorative surface 52 move parallel to each other, but the distance does not change, such as... Figure 4 As shown, the first connector 101 and the second connector 102 are subjected to the force of the decorative surface, causing the sliding connecting rod 30 to rotate around the rotation axis 201. Since the closing device in this embodiment will also change accordingly after the relative position of the decorative surfaces on both sides of the curtain wall expansion joint changes, the closing device in this embodiment has the problem of strong adaptability, so as to improve the reliability of the expansion joint closing.
