[0002] Internal and external corners are one of the building structures, referring to the corners formed by the intersection of two walls. The internal corner refers to the recessed corner, such as the angle between the ground or ceiling and the surrounding walls; the external corner refers to the protruding corner, such as the angle formed by two walls at the turning of a walkway. Since the internal and external corners are the angles formed by the intersection of two walls, there are easily gaps between the two walls. Therefore, the waterproof treatment of internal and external corners is particularly important in building waterproof construction.

[0003] In the Chinese invention with the publication number of CN108442540A, an internal corner waterproof structure and its construction process are disclosed. The internal corner waterproof structure includes at least one layer of rubber-like waterproof coating and at least one layer of carcass, and the whole waterproof structure is closely attached to the internal corner base surface.

[0004] Although the above patent can play a waterproof role for the internal corner, when laying the waterproof coating and the carcass on the internal corner, an arc angle is first set at the internal corner to facilitate the laying of the waterproof coating and the carcass. However, this arc angle is formed by construction workers using mortar for manual piling and arc treatment, which is time-consuming and laborious. Moreover, during the arc treatment process, there will be an angular deviation in manual arc treatment, resulting in inconsistent angles of the entire arc angle, making the waterproof coating and the carcass laid subsequently unevenly stressed on the arc angle and easily cracking, affecting the waterproof effect.
