The upper surface base 1 can be attached by a long screw combined with an attachment hole penetrating from the upper surface side to the bottom surface side of the joist material in addition to screwing from the bottom surface side.
Although illustration is omitted, when the diameter of the circular plate 11 is 100 millimeters, the upper surface side of the upper surface base 1 opposite to the formation side of the small cylinder 12 having an outer diameter of 51 millimeters is 10 By forming V-shaped grooves having a depth of 1.0 mm, which form squares with a millimeter interval, vertically and horizontally, the contact force with the joists on the wood deck side can be increased.

As shown in FIG. 4, the strut 2 has a spherical shape having a thread slightly formed on the outer peripheral surface thereof, for example, on the lower end side of the hollow cylinder 21 having an outer diameter of 39 mm, and having a diameter slightly larger than the outer diameter of the hollow cylinder 21. The end 22 is integrally formed.
For example, when the outer diameter of the hollow cylinder 21 is 39 millimeters, the spherical end 22 is formed to have a diameter of 40 millimeters.
In addition, since this support | pillar 2 is formed with the plastic resin, in order to adjust the height required at the time of construction, it can carry out easily by cutting an upper part with a saw etc. with an installation state. Is possible.

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 mark of the installation location is directly visually confirmed through the small aperture 31 in the central portion in the state where the bundle corresponding to the inclination of the present embodiment is placed at the installation location. Therefore, the installation work becomes extremely easy.

At this time, in the state where the bundle corresponding to the inclination of 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 in the center.
After confirming the installation position, the two corresponding screw holes 32a on the opposite side to the slit 33 forming side are screwed and partially fixed for each bundle corresponding to the inclination.
After that, by fitting the spherical end 22 of the support column 2 into the recess housing 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 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 fitting of the pillars 2 into the tilt-corresponding bundle is completed, the entire lower 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.
