This conventional channel member 10 is formed by cutting a long and wide steel plate surface-treated by, for example, galvanization to a required length and width, and then forming it into a U-shaped cross section by cold forming. A base portion is formed at the edge 10b (cut end surface perpendicular to the plate axis) and the wood end 10a (cut end surface parallel to the plate axis) of the shaped material 10, and thus these edge portions 10b
In addition, the wood ends 10a require repair for rust prevention, and the repair work requires a lot of trouble and time. In addition, the surface plating layer of the steel plate is indicated by reference numeral f in FIG.

In addition, since the bending radius R2 of the outer corner becomes a radius 2t corresponding to twice the normal plate thickness t, the roundness (R) of the corner increases. Therefore, when this profile 10 is used by being joined or abutted to another architectural profile or the like, there is an inconvenience that the contact area with the other architectural profile or the like is reduced by the larger roundness of the corner. There is.

所定の長さに切断される。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an architectural section 1 made of a channel having a U-shaped cross section according to the present invention. The architectural profile 1 is made of a long and wide thin steel plate surface-treated by galvanizing, for example, a length of 3600 mm and a width of 350 mm.
Then, the cut steel sheet is formed into a double U-shape in a state in which the cut steel sheet is adhered in a double layer by roll forming and the ends of the steel sheet are butt-joined. In this case, the sheet thickness of the steel sheet before being formed into a double-layered U-shaped cross section is 1.20 mm (net thickness 1.15 mm + galvanized layer thickness 0.025 mm × 2), and the double-layered cross section The plate thickness t of the U-shaped profile 1 is substantially 1.20 mm × 2 = 2.40 mm. As shown in FIG. 1, the butt joints 2 between the wood ends of the steel plate are located at the center of the inner surface of the U-shaped section 1. The building profile 1 is cut to a predetermined length required for use.

被膜を形成すればよい。According to this architectural profile 1, only the edge 4 of the profile 1 is exposed when the profile 1 is cut, and the conventional building profile 10 shown in FIG. As can be seen from FIG. 1, the edge portion 3 corresponding to 10a is a bent portion of a steel sheet adhered in a double layer, and the surface of the edge portion 3 is in a state covered with a galvanized layer f. Further, since the wood ends of the steel sheet forming the profile 1 are butt-joined to each other in a close contact state, rust-proofing treatment of the joined portion is not particularly required. Therefore, only the fore-edge 4 of the profile 1 needs to be repaired for rust prevention. For repairing the fore-edge 4, a rust-preventive coating may be formed on the fore-edge by painting or spraying with a rust preventive.

Since the base portion exposed to the fore edge 4 is reduced by the interposition of the forehead 4, and the architectural profile 1 is used after being cut to a required length, the inner and outer sides of the fore edge 4 are plated at the time of the cutting. The cut edges of the layers f, f and the cut edges of the intermediate plating layers f, f are wrapped freely and become wrapped around the base portion, thereby reducing the base portion exposed to the fore-edge 3. Therefore, repair on rust prevention at the fore edge 4 can be easily performed.

も同様に発揮される。Further, according to the architectural profile 1, as shown in FIG. 2, when the plate thickness is the same as that of the conventional profile 10 shown in FIG. Bending radius R1
Is a radius corresponding to approximately one half of the plate thickness t, that is, t / 2
In addition, the bending radius R2 of the outer corner is a radius corresponding to approximately ２ of the plate thickness t, that is, 3t / 2, and the radius of the corner of the profile is made as small as possible in comparison with the conventional building profile 10. Can be sharpened. This allows the corners of the profile to be used effectively. Such an effect is obtained by forming a metal plate, which has not been subjected to a surface treatment such as plating, into a double-layered shape and forming the required cross-sectional shape in a state where the metal ends of the metal plate are butt-joined. The same applies to materials.

By passing the sheet through a forming roll group (not shown) of the forming apparatus, as shown in FIGS. 1 to 3, the both ends 5a of the steel plate 5 gradually become tubular so as to approach each other at a position directly above the center in the width direction. The two ends 5a, 5a of the steel plate 5 are butt-welded to form a tubular body 6 having a circular cross section as shown in FIG. Immediately after this welding, the outer bead raised portion (not shown) of the butt weld portion W is cut flush with the outer surface of the tubular body 6 with a cutting bit or the like, and the weld portion W from which the bead raised portion has been cut off is cut.
On the outer surface, a rustproof coating is formed by thermal spraying (not shown).

It is formed into a shape, and the base of the metal plate is exposed only at the edge of the profile, and the edge of the profile of the present invention corresponding to the wooden end of the conventional architectural profile has a double layered shape. Since the bent portion of the metal plate is in close contact with the ridge, repairing on rust prevention only needs to be performed on only the fore-edge of the profile, so that repair of the profile can be reduced as much as possible in comparison with the conventional profile.

When the profile is cut to the required length and used, the double surface treatment layer in the middle part of the fore edge is wrapped up with the surface treatment layers on both the inner and outer sides. Since the base portion is wrapped around the base portion, the base portion exposed to the fore edge is further reduced.
Furthermore, according to this building profile, the bending radius of the inner corner and the bending radius of the outer corner at the corner of the profile can be made smaller and sharper than the conventional profile, so that the corner of the profile can be sharpened. Can be used more effectively than conventional profiles.
