DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be specifically described with reference to the drawings.
Here, in the accompanying drawings, the same reference numerals are given to the same members, and redundant descriptions are omitted.
In addition, since description here is one form by which this invention is implemented, this invention is not limited to a corresponding form.

  The marker-corresponding bundle according to the present embodiment is suitable for use when constructing a wood deck, and can be used on a flat ground as shown in FIG. 1 (a), but is particularly inclined as shown in FIG. 1 (b). Suitable for use in

  As shown in FIG. 2, the marker-corresponding bundle of the present embodiment includes an upper surface base 1 serving as a lid made of polypropylene resin, a support 2 made of polypropylene resin in which the upper surface base 1 and the upper end side are combined, and the support 2. And a lower surface base 3 made of polypropylene resin to be combined with the lower end side.

The upper surface base 1 is attached to the bottom surface side of the joist material that supports the floor plate by, for example, screwing or the like, and as shown in FIGS. The small cylinder 12 in which a thread groove capable of screwing the upper end side is formed on the inner surface side is integrally formed.
2 and 3, reference numeral 13 denotes vertical ribs provided at six locations on the outer periphery of the small cylinder 12 at the same interval.
Although not shown in detail, when the diameter of the circular plate 11 is 100 mm, the upper surface side of the upper surface base 1 that is opposite to the formation side of the small cylinder 12 having an outer diameter of 51 mm is provided on the upper surface side. By forming V-shaped grooves having a depth of 1.0 mm that form squares at intervals of 10 mm vertically and horizontally, the contact force with the joist on the wood deck side can be increased.

As shown in FIG. 4, the support column 2 is formed by integrally forming a spherical end 22 on the lower end side of the hollow cylinder 21.
The inside of the spherical end 22 is formed hollow, and a through hole 22a for draining water penetrating from the inside to the outside is formed in a central portion located at the lowermost part.
In addition, a smooth surface 23 for marking is formed at two places (see (a) in the figure) on the side surface along the length direction of the support column 2.
The smooth surface 23 is a marking-corresponding surface and is gray-coated as a process for facilitating marking with a pencil or the like.

A screw thread is formed on the outer peripheral surface of the hollow cylinder 21 other than the smooth surface 23.
For example, the spherical end 22 having a diameter of 40 mm can be integrally formed on the lower end side of the hollow cylinder 21 having an outer diameter of 39 mm.
Here, the smooth surface 23 can be formed on the hollow cylinder 21 by performing a process of scoring the side surface with an L-shaped blade in the vertical direction on the hollow cylinder 21 having the entire thread formed thereon. .

As shown in FIG. 5, the lower surface base 3 is formed by integrally forming a flange 32 on the outer periphery of a small cylindrical recess housing 31 that is combined with the spherical end 22 of the support 2.
The recess housing 31 and the flange 32 are continuously formed with slits 33 so that the recesses expand when the spherical end 22 is combined.
Although not shown in the drawings, when the diameter of the flange 32 is 100 millimeters, the bottom surface of the lower surface base 3 opposite to the formation side of the recess housing body 31 having an outer diameter of 50 millimeters is 10 The contact force with the installation surface side can be increased by forming V-shaped grooves having a depth of 1.0 mm that form squares with a millimeter interval vertically and horizontally.

The concave housing 31 has a small hole 31a penetrating to the bottom surface at the center, and the slit 33 is formed continuously to the small hole 31a.
Here, by forming the small hole 31a in the central portion, the marker of the installation location is directly visually confirmed through the small hole 31 in the central portion in a state where the marker corresponding bundle of the present embodiment is placed at the installation location. Therefore, the installation work becomes extremely easy.

The diameter of the upper end side of the concave portion of the concave housing 31 is smaller than the diameter of the spherical portion of the spherical end portion 22. For example, when the diameter of the spherical end portion 22 is 40 mm, the diameter is 38.7 mm. Yes.
In addition, the diameter of the upper end side of the recess of the recess housing 31 indicates the length from one end of the inner diameter portion to the opposite end, excluding the thickness of the small cylindrical recess housing 31.
In this way, the diameter of the upper end side of the concave portion of the concave housing 31 is made smaller than the diameter of the spherical portion of the spherical end portion 22, so that when the column 2 is combined with the lower surface base 3, the column 2 It becomes difficult to come off and the holding power can be increased.

Two locking pieces 34 for closing the slits 33 in the vertical direction are formed on the outer surface of the recess housing 31 so as to sandwich the formation positions of the slits 33 on the lower surface base 3.
As shown in FIG. 2, the locking piece 34 is formed with a screw hole 34 a through which a fastening screw 35 for fastening passes.

In FIG. 5, 32 a is a screw hole for fixing to an inclined ground formed on the flange, and 36 is a triangular rib formed integrally with the recess housing 31 and the flange 32 in a triangular shape.
The triangular ribs 36 are formed at three positions every 90 degrees except for the positions where the slits 33 are formed.

  Next, a usage example of the marker correspondence bundle will be described.

A required number of lower surface bases 3 are arranged at predetermined locations on an inclined surface which is an installation surface.
At this time, in the state where the marker-corresponding bundle according to the present embodiment is placed at the installation location, the mark of the installation location can be directly visually confirmed through the small hole 31 at the center.
Here, after confirming the installation position, a part of the lower surface base 3 is fixed by screwing the bundle corresponding to each marker using the two screw holes 32a on the opposite side to the slit 33 formation side. .
Thereafter, when the spherical end portion 22 of the support column 2 is temporarily fitted into the recess housing body 31 of the lower surface base 3, the position of the lower surface base 3 is not displaced, so that the fitting operation is facilitated.
Here, when the spherical end portion 22 of the support column 2 is temporarily fitted into the recess housing 31, the slit 33 is temporarily expanded, so that it can be easily combined.
Further, in the combined state, the diameter of the upper end side of the recess housing body 31 is slightly smaller than the diameter of the spherical end portion 22, so that it is possible to adjust the inclination angle while preventing the support column 2 from coming off and increasing the holding force.

When the insertion of the column 2 into the marker-corresponding bundle is completed, as shown in FIG. 6, leveling is performed using a laser level.
Then, as shown in FIG. 7, marking is performed at a predetermined position on the smooth surface 23 using a pencil or the like.

After completion of marking, the support column 2 is removed from the lower surface base 3, and the marking position of the smooth surface 23 of the hollow cylinder 21 is cut with a cutter as shown in FIG.
At this time, since there is no fear of damaging other construction sites such as the floor surface by the cutting operation, the cutting operation can be easily and quickly performed.

After the cutting, as shown in FIG. 9, the support column 2 is attached to the lower surface base 3.
Here, the entire bottom surface base 3 is fixed by screwing the remaining two screw holes 32a.
In addition, the lower surface base 3 and the support | pillar 2 can also be fixed with an adhesive agent as needed.
Further, by using the screw hole 34a formed in the locking piece 34 and tightening with the tightening screw 35, the combined spherical end 22 can be firmly fixed.

After fixing, as shown in FIG. 10, the upper surface base 1 is fitted into each column 2 to form a lid.
Thereafter, if necessary, each column 2 is adjusted to a vertical state.
At this time, a vertical level can be easily adjusted by placing a level on the upper surface base 1.

Even in an inclined place, in a state where the support column 2 is combined with the lower surface base 3 so as to stand upright, the hemispherical portion corresponding to the lower half of the spherical end portion 22 of the support column 2 is substantially the entire surface of the recess of the recess housing 31. By contacting, it becomes possible to support a load over a wide area, and even if it is made of resin, it has sufficient strength.
Further, by providing the small hole 31a in the center of the recess housing body 31, the lowermost end portion of the spherical end portion 22 and the peripheral edge of the aperture portion come into contact with each other, so that the load can be received more efficiently.
Further, the small hole 31a also functions as a drain.
