[0157] The construction method of this utility model is as follows:

[0158] The support element 111 is fixed to the external corner of the building with screws;

[0159] A plurality of first mounting elements 121 are spaced apart and mounted to the outside of the support element 111;

[0160] The second decorative unit 160 and the third decorative unit 160 are fixed to both sides of the building's external corner, so that the end of the second decorative unit 160 abuts against the first positioning element 131 and the end of the third decorative unit 160 abuts against the second positioning element 141.

[0161] The first sealing element 151 and the second sealing element 152 are respectively filled between the second decorative unit 160 and the first connecting element 132, and between the third decorative unit 160 and the second connecting element 142;

[0162] The second snap-fit ​​element 161 is snapped into the first snap-fit ​​element 122, so that the first decorative element 162 covers the first sealing element 151 and the second decorative element 163 covers the second sealing element 152.

[0163] The advantages of this utility model are basically the same as those of Embodiment 1, and will not be repeated here.

[0164] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
