[0003] Corner sealing is a specialized method used to ensure a tight seal at the joint between two adjacent materials or components at right angles (i.e., corners) during construction, renovation, or certain engineering projects. This method must balance structural stability and aesthetics while preventing the penetration of moisture, air, and dust, placing high demands on process precision and the selection of sealing materials. However, existing corner sealing methods offer poor sealing performance after installation, leading to air and rain leaks. Furthermore, the joint requires the application of glue, which can easily lead to visual unevenness. Utility Model Content

The cross-sections of the first rubber strip slot and the second rubber strip slot are both arc-shaped. Foam strips are installed on both the first rubber strip slot and the second rubber strip slot.

[0008] Furthermore, the corner aluminum profile further includes a supporting edge, one end of which is fixed on the oblique side, and the other end of which is fixed on the connection between the two right-angle sides.

[0009] Furthermore, the thermal insulation component includes two thermal insulation aluminum profiles, both ends of the thermal insulation aluminum profiles are provided with dovetail structures, and the beveled edges and the butt joint aluminum profiles are provided with dovetail grooves, and the dovetail structures at both ends of the thermal insulation aluminum profiles are respectively inserted into the dovetail grooves on the beveled edges and the butt joint aluminum profiles.

[0010] Furthermore, V-shaped mounting grooves are provided on the short horizontal sides and the butting aluminum profiles.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention is installed by self-tapping screws, and no glue is required at the joints, which solves the quality problems that occur during the construction and gluing process; and secondary sealing is achieved through the foam strips between the right-angled edges and the frames, and between the butt-jointed aluminum profiles and the frames, which solves the problems of traditional corner air leakage and rain leakage, and the corner sealed splicing is made up for the problem of weak strength of the frames themselves by inserting two frames and then firmly connecting them with self-tapping screws. After installation, it has the advantages of beautiful visual plane, flatness, and waterproofness. BRIEF DESCRIPTION OF THE DRAWINGS
