Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to an arc-shaped inner corner line for a waterproof base layer. Background Art

[0002] At the inner corners where the facade and plane of the existing concrete structure meet, manually mixed mortar is used to smooth out the arc corners, which causes cracking, shrinkage, poor arc corner forming, and a loose bonding surface with the concrete base. As a result, the laid waterproof membrane becomes broken, cracked, hollow, and unstable at the inner corners. Once the waterproof membrane is damaged, it will directly lead to leakage risks. Utility Model Content

[0003] The purpose of the utility model is to provide a kind of circular arc internal corner line for waterproof base layer which has simple structure, convenient construction, reduces the cost of labor, materials, etc., reduces the time of workers for detailed processing of the circular arc corner mortar base layer at the internal corner, and at the same time does not need to wait for the circular arc corner of the mortar to dry before laying the waterproof membrane, so that the waterproof layer can be constructed in advance and the construction period can be shortened.

[0004] The utility model is achieved through the following measures:

[0005] A circular arc inner corner line for a waterproof base layer, characterized by comprising a middle section component and right-angle pieces arranged at both ends of the middle section component;

[0006] The middle section assembly includes a middle section inner corner line and an end inner corner line;

[0007] A rectangular limiting column is arranged at the end of the end inner angle line, and a rectangular slot is opened at the bottom of both ends of the right-angle piece, and the rectangular limiting column is arranged in the rectangular slot.

[0008] The specific features of the utility model also include:

[0009] The end surfaces of the middle section inner corner line and the end inner corner line are arc surfaces.

[0010] Threaded holes are provided at both ends of the end inner angle line, and connecting studs are provided on the side of the rectangular limit column, and the connecting studs are arranged in the threaded holes;

[0011] The connecting stud can be installed at any end of the end inner angle line according to installation requirements.

[0012] The middle section inner corner line and the end inner corner line are fixed on the concrete structure surface by structural adhesive.

[0013] During the construction and installation, the installation is carried out from the inner corner on one side, and the right-angle piece and the end inner corner line are installed in place. At the same time, the end inner corner line is fixed to the inner corner of the concrete structure surface by structural adhesive. The middle inner corner line of appropriate length is selected according to the length on site, and the middle inner corner lines are installed in sequence using structural adhesive. When approaching the inner corner on the other side, the end inner corner line is installed, and finally the right-angle piece is buckled on the end of the end inner corner line. After the installation of the arc-shaped inner corner lines of each part is completed, the additional layer of waterproof membrane can be laid.

[0014] The beneficial effects of the utility model are: simple structure, convenient construction, reduction of labor, material and other costs, reduction of workers' time for detailed processing of the mortar base layer of the arc corner at the inner corner, and no need to wait for the mortar arc corner to dry before laying the waterproof membrane, so that the waterproof layer can be constructed in advance and the construction period can be shortened.
