As a result, it is possible to prevent water on the inner surface side of the building bar member and prevent corrosion damage to the building bar member and the mounting bracket fixed thereto.

  Moreover, it is preferable that the drain hole is formed in the corner part of a bottom plate and a side plate. Thus, by forming a drain hole in the corner portion, it is possible to reduce the surface tension of water and promote drainage through the drain hole. Moreover, since the surface tension of water can be reduced, drainage can be promoted suitably even if the drain hole is made smaller.

  Moreover, it is preferable that a plurality of drain holes are formed at equal intervals along the longitudinal direction of the side plate. Thereby, the length of the bar member for construction can be easily grasped by using the number of drain holes as a guide. Moreover, the attachment position of the board etc. which are attached to a building bar member can be easily grasped | ascertained by setting the position of the drain hole as a mark.

  ADVANTAGE OF THE INVENTION According to this invention, the water supply by the inner surface side of a building bar member can be prevented, and the corrosion damage of a building bar member and the attachment metal fitting fixed to this can be prevented.

  Hereinafter, preferred embodiments of an architectural bar member according to the present invention and a ceiling base material provided with the same will be described with reference to the drawings. In the description of the drawings, the same or corresponding elements are denoted by the same reference numerals, and redundant description is omitted. For convenience of explanation, the extending direction (longitudinal direction) of the field edge receiver is the X-axis direction, and the extending direction (longitudinal direction) of the field edge is the Y-axis direction, the direction orthogonal to the X-axis direction and the Y-axis direction. Is described as the Z-axis direction. FIG. 1 is a perspective view showing a ceiling base material according to an embodiment of the present invention.

  A ceiling base material (steel base material) 1 according to an embodiment of the present invention supports a ceiling panel (not shown) of a building from above, and as shown in FIG. Is attached to a field edge (a bar member for construction, for example, a double field edge) 2, a field edge receiver 3 disposed above the field edge 2 to support the field edge 2, and the field edge 2 to the field edge receiver 3. The field edge 2 and the field edge receiver 3 extend in the horizontal direction and extend in directions orthogonal to each other.

  The field edge 2 has a substantially U-shaped cross-section, and extends in the Y-axis direction, and a pair of side walls (side plates) that are erected from both side edges of the base plate 2a and face each other. 2b, 2b, and a pair of lip walls 2d, 2d bent inward from the ends (open ends) 2c, 2c opposite to the base plate 2a of the pair of side walls 2b, 2b. ing.

  The field edge receiver (channel) 3 has a substantially U-shaped cross section and extends in the X-axis direction from a flat plate portion 3a and is erected in the Y-axis direction from both side edges of the plate portion 3a. And a pair of facing wall portions 3b, 3b facing each other. The field edge receiver 3 is disposed on the field edge 2, and the facing wall portion 3 b on the lower side of the field edge receiver 3 is in contact with the field edge 2.

  The clip 4 includes a locking claw bent downward from the upper facing wall portion 3b of the field edge receiver 3, a root portion 4b disposed on the upper facing wall portion 3b of the field edge receiver 3, and the root portion. A plate portion 4c that is bent downward from 4b and extends in the Z-axis direction (vertical direction); and a projection portion 4d that is formed at the lower portion of the plate portion 4c and engages with the lip wall 2d of the field edge 2. ing.

  Here, in the field edge 2 of this embodiment, the drain hole 2g is formed in the corner part 2f of the base board 2a and the side wall 2b. The drain hole 2g penetrates the base plate 2a and the side wall 2b and discharges the water in the field edge 2 to the outside. A plurality of the drain holes 2g are formed and arranged at equal intervals along the Y-axis direction (longitudinal direction of the field edge 2). This drain hole 2g is formed by processing with a drill, for example.

  In such a ceiling base material 1, the water drainage hole 2 g is formed in the corner portion 2 f of the base plate 2 a and the side wall 2 b of the field edge 2, so that water has entered the field edge 2. However, it can drain suitably through the drain hole 2g. Thereby, the aquifer on the inner surface side of the field edge 2 can be prevented, and corrosion damage to the field edge 2 and the mounting bracket (for example, board screw) fixed thereto can be prevented. As a result, it is possible to prevent the board from falling by preventing the field edge 2 and the board screw from being pulled out.

  Moreover, since the drain hole 2g is formed in the corner part 2f of the base plate 2a and the side wall 2b, it is possible to reduce the surface tension of water and to promote drainage through the drain hole 2g. it can. Moreover, since the surface tension of water can be made small and drainage can be promoted, the drain hole 2g can be made small.

  Moreover, since the water drain hole 2g is formed in plural along the longitudinal direction (Y-axis direction) of the field edge 2 at equal intervals, the length of the field edge 2 is determined by using the number of the water drain holes 2g as a guide. It can be easily grasped. Moreover, by using the position of the drain hole 2g as a mark, the board mounting position can be easily grasped, and the workability at the time of mounting can be improved.
