[Detailed explanation of the invention] [Purpose of the invention] (Field of industrial application) The invention relates to building materials, for example, the upper surface of a rising wall formed around the periphery of a concrete building's roof can be covered with a hollow columnar material such as a decorative frame. Regarding the configuration of the connection part.

(Prior Art) Conventionally, when connecting hollow columnar members formed by bending metal plates in the width direction, as shown in FIG. Connecting end surfaces 5 and 6 are formed at each connecting end with the columnar material 2 by a plurality of connecting pieces 3 and 4 made of metal plates, and a joint receiving part 7 protruding from one connecting end surface 5 is connected to the other connecting end. The connecting end surface 5 is fitted into the opening 8 of the end surface 6,
A structure in which a concave groove formed by the joint receiving part 6 and the joint receiving part 7 is filled with caulking material and connected to each other is known.
When forming the connecting end surfaces 5 and 6, the columnar material 1 is made of an elongated metal material having an L-shaped cross section or an elongated metal material with one side of the elongated metal material having an L-shaped cross section bent further outward.
A plurality of connection pieces 3 and 4 are attached to the inner walls of the connection ends of the columnar members 1 and 2 with adhesive. The method of gluing was used.

(Problems to be Solved by the Invention) When using the conventional method shown in FIG. It is difficult and dangerous to cut on site as it takes time and effort to cut the pillars 1 and 2, and even if they are cut in advance at the factory, they may not match on site due to errors in the dimensions of the pillars 1 and 2. Moreover, when the pillars 1 and 2 have curved surfaces or small steps, it is troublesome to match the shape of the connecting piece 3. In addition, since the shapes of the columnar members 1 and 2 are diverse, the connecting pieces 3 and 4 must be created each time as needed, resulting in poor efficiency and the inability to respond quickly.
