Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is an exploded view of an eaves hook support 21 shown as an actual embodiment of the present invention.
As shown in FIG. 1, the eaves support 21 is attached to a nose cover plate 22 containing a cement-based material or a plasticizer containing an alkaline component, and is mounted with an eaves support 27. A spacer 24 made of an alkali-resistant resin material or a resin material not containing a plasticizer, which will be described later, is interposed between the mounting portion 23 and the nose masking plate 22. The mounting portion 23 and the spacer 24 are attached to the nose masking plate 22 by screws 25. It is to be fixed.

  The eaves support 21 includes the above-described mounting portion 23 that is attached to the nose cover plate 22 and the eaves support portion 26 that protrudes from the surface of the mounting portion 23 toward the eaves tip (not shown). The eaves rod 27 is mounted below the rod support portion 26.

  As shown in FIG. 2A, the attachment portion 23 is a plate formed in a substantially T shape.

  A through hole 28 through which the screw 25 shown in FIG. 1 is inserted is formed in the left and right ends of the upper side plate portion of the mounting portion 23 and the lower end portion of the plate portion extending downward.

  The through hole 28 is a hole having a circular cross section formed so that the diameter thereof is substantially the same as the diameter of the screw portion 25a of the screw 25, and in a direction perpendicular to the surface of the mounting portion 23 as shown in FIG. Is formed.

  The eaves support portion 26 protrudes in the protruding direction of the eaves edge, and includes ear portions 26a and 26b for engaging the engaging portions 27a and 27b on the upper edge of the eaves eaves 27.

  As shown in FIG. 2B, the spacer 24 is a plate body having a shape viewed from the front so as to be substantially the same as the mounting portion 23, and forms a wall portion into which the screw 25 is screwed. It has a thickness dimension of about 10 mm.

  As shown in FIGS. 1 and 2B, screws 25 are screwed into the front surface F of the spacer 24 with which the mounting portion 23 abuts at positions corresponding to the through holes 28, 28,. Are formed as recesses 29, 29,.

  The recess 29 has a circular shape with a smaller diameter than the through hole 28 and is formed so as to be recessed by a certain dimension in the thickness direction of the spacer 24. As shown in FIG. 3, the bottom surface 30 of the recess 29 and the spacer 24 A space between the rear surface B and the rear wall B is a solid wall portion 31 into which the screw 25 can be screwed.

  As described above, the spacer 24 is not formed with a screw-penetrating hole in the wall portion through which the screw 25 is penetrated, and the spacer 24 is configured to have no hole. The rear surface B of the recess 29 is formed flat.

  The depth of the recess 29 is such that when the tip of the screw 25 is inserted, the alignment of the mounting portion 23 and the spacer 24 is facilitated by aligning the axes of the through hole 28 and the recess 29. Depending on the thickness dimension, the dimension is set to about 2 mm to 3 mm.

In the above configuration, the eaves support 21 is formed of a polycarbonate resin from the viewpoint of, for example, corrosion resistance, impact resistance, flame retardancy, and the like.
The spacer 24 is formed of an alkali-resistant resin material or a resin material that does not contain a plasticizer as described above, and is formed of, for example, a hard vinyl chloride resin. The plasticizer-resistant resin material is more preferably a resin that does not contain a plasticizer and is difficult to infiltrate the plasticizer.

Next, the construction method of the eaves rod support tool 21 will be described.
In order to attach the eaves support 21 to the nasal concealment plate 22, as shown in FIG. 24, and the mounting portion 23 of the eaves support 21 is disposed on the front surface F of the spacer 24, and the recess 29 of the spacer 24 is visually recognized from the through hole 28 and aligned.

Then, the screw 25 is inserted through the through hole 28 of the mounting portion 23, and the tip of the screw 25 is brought into contact with the recess 29. At this time, since the recess 29 is formed to have a smaller diameter than the through hole 28, the through hole 28 and the recess 29 can also be obtained by fitting the screw 25 into the recess 29 and matching the axis of the through hole 28. Can be easily aligned.
When the through hole 28 and the recess 29 are aligned as described above, the screw 25 is pressed and rotated and screwed into the solid wall 31 of the spacer 24, as shown in FIG. Twenty-five screw threads 36 cut through the material 40 of the spacer 24 and enter the inside of the material 40 while opening the material 40.

  At this time, since the reaction force against the screw portion 25a is generated in the material 40 of the spacer 24 pushed outward by the screw 25, the material 40 is formed in the screw valleys 37, 37,. Enters and the material 40 comes into close contact with the thread 36 and the thread valley 37.

  When the screw 25 is further rotated and the screw portion 25 a of the screw 25 enters the nose cover plate 22, the material 40 in the vicinity of the opening on the rear surface B side of the spacer 24 is concealed as the screw 25 advances. Slightly extends to the plate 22 side. When the head portion 25b of the screw 25 comes into contact with the front surface of the attachment portion 23, the attachment of the eaves pad support 21 to the nose cover plate 22 is completed as shown in FIG.

  As described above, the screw 25 is interposed by interposing the non-hole spacer 24 having the recess 29 between the nose cover plate 22 and the attachment portion 23 and having no hole formed in advance in the portion through which the screw 25 passes. By screwing in, the material 40 of the spacer 24 is brought into close contact with the surface of the screw portion 25a of the screw 25 as shown in FIG. 3, and the gap between the nose cover plate 22 and the mounting portion 23 is blocked. Accordingly, a cement-based material containing an alkali component generated by screwing the screw 25 into the nose cover plate 22 or a chip containing a plasticizer is formed in the mounting portion 23 through the hole 38 formed in the spacer 24. The effect that it can prevent that a crack generate | occur | produces by moving in the through-hole 28 made and adhering to the attachment part 23 formed with the polycarbonate is acquired.

  Further, when the screw 25 is screwed, a recess 29 having a smaller diameter than the through hole 28 is formed at a position corresponding to the through hole 28, and the position of the recess 29 can be confirmed from the through hole 28. Since the tip of the screw 25 inserted through the hole 28 can be fitted into the recess 29, the alignment of the through hole 28 of the mounting portion 23 and the recess 29 of the spacer 24 is facilitated, and the spacer 24 of the screw 25 is made. It becomes easy to screw in.

  Further, a simple structure in which the attachment portion 23 is attached to the nose cover plate 22 by the screw 25 using the non-hole spacer 24 in which the recess 29 is formed. Since the tip of 25 can be guided appropriately, the effect that attachment work of eaves-rod support tool 21 which can prevent crack of attachment part 23 is simple is acquired.

  The recess 29 is formed so that the bottom surface 30 having a certain size is flattened, but the bottom surface 30 may have a taper shape in which the diameter is gradually reduced toward the rear surface B of the spacer 24. By forming the recess 29 in such a shape, it is easier to screw the screw 25 into the spacer 24.

  In the above embodiment, the rear surface B of the spacer 24 that contacts the nasal concealment plate 22 is formed flat, but as shown in FIGS. 5 (a) and 5 (b), it surrounds the solid wall 31 and A groove 39 for discharging chips and rainwater from the nose cover plate 22 may be formed so as to communicate downward.

  The shape, width, and depth of the groove 39 are not particularly limited as long as the chips and rainwater can be discharged. However, the shape and width are in consideration of the strength of the spacer 24. It is assumed that chips and the like are more easily discharged, and the depth dimension takes into consideration the thickness dimension of the spacer 24, the depth dimension of the recess 29, the strength of the solid wall portion 31 into which the screw 25 is screwed, and the like. And about 1 mm to 3 mm.

  By forming such a groove 39 on the rear surface B of the spacer 24, the cement containing material containing an alkali component generated when the screw 25 is screwed into the nasal concealment plate 22 or chips containing a plasticizer can be used. 24 can be discharged below, and the transition of these chips to the mounting portion 23 side can be more reliably prevented.
