The lower cap 16 is not shown in detail, but is fixed to the lower end of the profile 13 with screws. Note that a drain hole is formed in the lower cap 16 at a position corresponding to the hollow portion 13 a of the profile 13.

Next, in the building material 1 according to the embodiment of the present invention, a method, an operation, and an effect of attaching the upper cap 15 to the shape member 13 will be described.
As shown in FIGS. 2 and 6, the insertion wall portion 21 of the upper cap 15 is inserted into the hollow portion 13 a from the upper end of the shape member 13, and the insertion protrusion 23 of the upper cap 15 is inserted into the inserted portion of the shape member 13. The upper cap 15 is pushed into the shape member 13 by being inserted into the 19 space portions 19 a.
As shown in FIG. 1, when the insertion protrusion 23 is pushed into the space 19 a of the inserted portion 19, the tip portion of the pressing portion 35 does not completely enter the inserted portion 19, and the protruding portion is shaved. It becomes the marginal part 35b, and presses the insertion part 19 strongly while being cut out. The shaving allowance 35b that has been shaved out is discharged into the hollow portion 13a of the profile 13 as shavings.
A reaction force F that presses the inner wall 13b of the shape member 13 acts on the pressing portion 35, and the pressure contact surface 39 on the opposite side of the pressing portion 35 is strongly pressed by the inner wall 13b of the shape member together with the pressing portion 35. Press contact.

The press-fit portion 37 of the insertion protrusion 23 is inserted into the inserted portion 19 while being pressed against the inner wall 19 b of the inserted portion 19 of the profile 13.
Each auxiliary pressing portion 33 provided on the outer peripheral side surface of the insertion wall portion 21 abuts on the inner wall 13b of the shape member 13 and fills the clearance K between the inner wall 13b of the shape member 13.
The auxiliary pressing portion 34 provided at the one end portion 21a and the other end portion 21b located at the discontinuous portion 25 of the insertion wall portion 21 is in contact with the outer wall of the insertion portion 19 and is connected to the insertion portion 19 of the profile 13. Fill the clearance between.

According to the building material 1 according to the embodiment of the present invention, the upper cap 15 is press-fitted into the hollow portion 13a of the profile 13 by the insertion protrusion 23 and the press-contact surface 39 of the upper cap 15, and is in a press-contact state even after press-fitting. Therefore, the upper cap 15 can be fixed to the shape member 13 without screwing.
As shown in FIG. 7, when the upper cap 15 is attached to a large number of profiles 13, as in the prior art, screw holes are formed in the profile 13 and the upper cap 15 one by one, or each upper cap 15 is profiled. Since it is not necessary to fix to 13 with a screw | thread, construction labor and material cost can be reduced.
Each of the auxiliary pressing portions 33 of the upper cap 15 is in contact with the inner wall 13b of the shape member 13 on two sides of one side and an adjacent side constituting the square with respect to the shape member 13 having a square section. Since the clearance K between the insertion wall portion 21 of the cap 15 and the inner wall 13b of the profile 13 is filled, it is possible to prevent the upper cap 15 from rattling against the profile 13.

Since the insertion protrusion 23 is provided with a press-fitting portion 37 for press-fitting into the inner wall 19a of the insertion portion 19, the insertion protrusion 23 can be prevented from rattling in the insertion portion 19, and the pressing by the pressing portion 35 can be stabilized. Can be done.
Since the press-fit portion 37 is provided next to the pressing portion 35 so as to contact the inner wall 19 b of the inserted portion 19, the press-fit portion 37 is scraped when the press-fit portion 37 is pressed into the inner wall 19 b of the inserted portion 19. Even if shavings come out, the design is good without shavings being exposed to the outside of the profile 13.
By being pushed into the inserted portion 19 while the pressing portion 35 is being cut, the cap can be further strongly fixed by pressing strongly against the shape member 13 after press-fitting.
Further, the insertion wall portion 21 of the upper cap 15 is provided with auxiliary pressing portions 34 that contact the outer surface of the insertion portion 19 at the end portions 21a and 21b facing each other with the discontinuous portion 25 interposed therebetween. Shaking with respect to the insertion portion 19 can be prevented.
