  Hereinafter, the best mode for carrying out the present invention will be described.

  The protruding corner member A of the present invention is formed by joining a pair of protruding corner halves 5 and 5. As shown in FIG. 2A, a plurality of protruding corner halves 5 can be cut out with a predetermined width from a substrate 20 such as a ceramic siding material or a resin molded plate having an uneven pattern on the surface. Here, a groove 1 and a ridge 2 that are long in the longitudinal direction (lateral direction) of the substrate 20 are formed on the surface of the substrate 20. Therefore, the long groove | channel 1 and the protruding item | line 2 which are long in the horizontal direction are also formed in the surface of the cut-out corner half body 5. Next, the inclined surface 6 is formed at the side end portion of the projected corner half body 5 by cutting the side end portion of the projected corner half body 5 having the grooves 1 and the ridges 2 on the surface thereof at about 45 °. Next, as shown in FIG. 2B, the pair of protruding corner halves 5 and 5 are joined in a substantially L-shaped cross section by abutting the inclined surfaces 6 and 6 and joining them with an adhesive or the like. At this time, the concave grooves 1 and 1 formed in the left and right protruding corner halves 5 and 5 and the ridges 2 and 2 are connected continuously. In this way, the long concave grooves 1 and the convex ridges 2 are formed in the lateral direction across the surfaces of the pair of protruding corner halves 5 and 5 connected to the left and right, and a plurality of the concave grooves 1 and the convex ridges 2 are alternately arranged vertically. Will be formed side by side.

  Moreover, when the long groove | channel 1 and the protruding item | line 2 which are long in the transversal direction (vertical direction) of the board | substrate 20 are formed in the surface of the board | substrate 20, it carries out as follows. First, as shown in FIG. 3A, a plurality of protruding corner half bodies 5 are cut out from the substrate 20 with a predetermined width dimension. Accordingly, the grooves 1 and the ridges 2 that are long in the vertical direction are also formed on the surface of the cut out half-finished half 5. Next, one of the upper end portion or the lower end portion of the projected corner half body 5 is cut by cutting one of the upper end portion or the lower end portion of the projected corner half body 5 having the concave grooves 1 and the protruding strips 2 on the surface. An inclined surface 6 is formed on the surface. Next, as shown in FIG. 3B, the pair of protruding corner halves 5 and 5 are joined in a substantially L-shaped cross section by abutting the inclined surfaces 6 and 6 and joining them with an adhesive or the like. At this time, the concave grooves 1 and 1 formed in the left and right protruding corner halves 5 and 5 and the ridges 2 and 2 are connected continuously. Next, a plurality of a pair of protruding corner halves 5 and 5 joined to the left and right are joined up and down. This joining is performed using an adhesive or the like. In this way, the long concave grooves 1 and the convex ridges 2 are formed in the lateral direction across the surfaces of the pair of protruding corner halves 5 and 5 connected to the left and right, and a plurality of the concave grooves 1 and the convex ridges 2 are alternately arranged vertically. Will be formed side by side.

  Next, the top surface 4 is formed by chamfering the top 3 of the ridge 2 at the joint portion between the pair of left and right protruding corner halves 5, 5. In this case, the depth (depth position) of the top surface 4 from the vertex C of the ridge 2 and the inclination angle of the top surface 4 with respect to the surface of the projected corner half 5 are made different for each ridge 2. The processing depth (depth position) X of the top surface 4 can be 0 <X ≦ √2d, where d is the depth dimension of the groove 1. Further, the angle of the top surface 4 can be set almost arbitrarily. That is, by changing the angle and depth of chamfering as shown by the dotted lines M1, M2, and M3 shown by dotted lines in FIGS. A plurality of types of top surfaces 4a, 4b,... With different depth positions from the vertex C can be formed. The range in which the top surface 4 can be formed connects the bottom vertex T of the groove 1 at the top 3 of the ridge 2 and the intersection P between the back surface extension line S of the projected corner half 5 and the surface of the projected corner half 5. It can be on the vertex C side of the ridge 2 from the limit line L. The range which can form the top surface 4 in FIG. 1 is shown with a dotted pattern. In addition, the depth dimension d of the ditch | groove 1 can be 7-11 mm, and the thickness dimension D of the protruding corner half body 5 can be 21-35 mm.

  In this way, the top surface 4 formed by chamfering on the ridges 2 arranged vertically is different from each other in at least one of the depth position from the vertex C of the ridge 2 and the angle with respect to the surface of the protruding corner half 5. By forming the seed top surfaces 4a, 4b..., As shown in FIG. 5, various top surfaces 4a, 4b... Can be formed, and a natural and uncomfortable appearance can be obtained. . The angles and depths of all the top surfaces 4 do not have to be different, and the angles and depths of several top surfaces 4 may be the same.

  In the present invention, before chamfering the top portion 3 of the convex portion 2, it is preferable to remove the adhesive protruding from between the bonded outer corner halves 5 and 5 throughout, thereby improving the appearance of the appearance. It can be improved. In FIG. 2B, the adhesive protruding from the surface of the joining portion of the protruding corner halves 5 and 5 joined to the left and right is removed, while in FIG. In addition to the adhesive that protrudes to the surface of the joint portion of the protruding corner halves 5 and 5 that are bonded to each other, the adhesive that protrudes to the surface of the bonding portion of the protruding corner halves 5 and 5 that are bonded vertically can also be removed.
