The Chinese utility model patent with the authorization announcement number CN218843472U discloses a glass curtain wall construction node structure, which is used to seal and dock two adjacent glass curtain wall units, and connect decorative parts on the outside of the connection seam between the two glass curtain walls. The glass curtain wall construction node structure includes a fixed frame and a decorative strip connecting plate for connecting glass panels. The decorative strip connecting plate includes a first fixed plate segment, a connecting plate segment, and a second fixed plate segment arranged in sequence. The first fixed plate segment is fixedly connected to the docking surface of one of the two fixed frames, and the second fixed plate segment is attached to the docking surface of the two fixed frames. The butt joint extends outward from the butt joint and connects the decorative parts. To ensure the sealing of the butt joint of the two fixed frames, it is necessary to set oppositely arranged sealing strips at the butt joint surfaces of the two fixed frames. The sealing strips are located between the first fixed plate segment and the second fixed plate segment. Since the connecting plate segment is attached to the butt joint surface of the fixed frame, the sealing strips are located on the butt joint surface of the fixed frame. Therefore, before arranging the sealing strips on the fixed frame connected with the fixed plate segment, it is necessary to cut the sealing strips into multiple sections first, and then install the multiple sections of sealing strips on the fixed frame connected with the fixed plate segment respectively, and arrange the adjacent sealing strips at both ends at intervals, and the intervals are equal to the width of the connecting plate segment, so as to allow the connecting plate segment to pass through.
