The invention belongs to the technical field of building materials, and particularly relates to a rod profile and an application structure thereof. The plurality of interface parts are integrally formed at the periphery of the rod body; the interface part is provided with a box-shaped T-shaped groove with a groove opening back to the rod body;
inverted T-shaped grooves are formed in the two side walls, close to the bottom of the box-shaped T-shaped groove, of the box-shaped T-shaped groove; the two side walls, close to a groove opening, of the box-shaped T-shaped groove are provided with inner protruding edges, and the inner protruding edges face the center of the box-shaped T-shaped groove. A V-shaped caulking groove is formed between every two adjacent connector parts. According to the scheme, the connector part of the rod profile adopts the
composite structure, so that various accessories can be conveniently connected with the rod profile in different forms, and holes and grooves in the rod profile are reduced; the connecting structure of the rod profile and the accessories can be in a detachable connection mode, so that the accessories can be increased, decreased and installed conveniently, the installation efficiency of the accessories is improved, and recycling and reusing of the accessories and the rod profile are facilitated.
