In any case, a constant ventilation space (S) is secured between the lower surface of the receiving material (X) and the upper surface of the foundation concrete (C) by the spacer plate (B). As a result, the receiving material (X) does not receive the moisture from the foundation concrete (C), which contributes to the improvement of its durability. In addition, the rotating material such as a wrench inserted from the ventilation space (S) without any trouble can be used. In addition, the pulling bolt described later can be surely rotated.

(7) is a drawing bolt receiving hole formed substantially at the center of the intermediate receiving seat (3) in the spacer plate (B), and (8) is both grounding leg seats (2) of the spacer plate (B). The mounting bolts (5) for the cap nut (2) are formed by opening the whole or a part of the hole, especially the elliptical shape. It is desirable to determine so that the position adjustment can be performed.

(9) is a drawing bolt receiving through hole vertically penetrating the receiving material (X), which is in communication with the drawing bolt receiving hole (7) on the spacer plate (B) side, and is provided with the spacer plate. A relatively long pulling bolt (10) is inserted from the lower part of (B) into the receiving member (X) so as to be erected.
(10a) is a large-diameter rectangular head of the pulling bolt (10), which is rotated by a turning tool such as a spanner inserted from the ventilation space (S).

On the other hand, at the lower end of the upright (column) (Y), a mortise pin receiving groove (11) which opens downward is formed into a blind hole having a constant depth (G). The pulling bolt receiving through hole (9) on the receiving material (X) side communicates with the receiving bolt (9). (D) shows substantially the same diameter of the matching communication.

(12) The tenon pin receiving groove (1)
A plurality of horizontal fixed pin receiving through-holes crossing 1) are also distributed at the lower end of the upright (Y) as adjacent mutually orthogonal directional states.

Further, (P) is a tenon pin used for assembling the upright member (Y) and its receiving member (X),

In that case, one of the pulling bolt (10) and the tenon pin (P) may be kept in a fixed state, and the other may be rotated.

Then, the body portion (13) of the tenon pin (P) protrudes from the upper surface of the receiving member (X) by a certain height and stands upright. The open tenon pin receiving groove (11) is dropped from above into the insertion state toward the tenon pin (P), so that the lower surface of the upright member (Y) (the cut end surface) becomes the receiving member (X). ) Is bonded to the upper surface.

Then, from the plurality of horizontal fixing pin receiving through holes (12) distributed in the vertical member (Y), the fixing pin receiving communication on the tenon pin (P) side which is in communication with the horizontal fixing pin receiving through hole. What is necessary is just to press-fit and integrate the fixing pins (A) into the holes (14) in a state of passing through the holes.

In the assembled state of the upright member (Y) and the receiving member (X) obtained by the above working method, the upright member (Y) is pressed into the tenon pin (P) by the fixing pin (A). ), The vertical member (Y) is still joined to the receiving member (X) by its own gravity, and is still tied up and fixed in the locked state. It is not integrated.

Therefore, in the present invention, finally, the pulling bolt (10) is rotated to operate the screw shaft (10b).
And the cap nut (17) on the mortise pin (P) side are completely tightened, so that the upright material (Y) is drawn into close contact with the receiving material (X) and fixed in the overall tied-up locked state. It is united.

Such a turning operation is performed by locking a turning operation tool such as a wrench inserted from the ventilation space (S) to the head (10a) of the pulling bolt (10), so that the receiving member ( X) can be executed without any trouble from outside.

As the fixing pin (A) of the upright (Y) mentioned above, it is preferable to adopt a metal product having the form shown in FIGS.

That is, in FIGS. 8 to 15, (18)

The mortise pin (P) shown in the first embodiment of FIGS. 1 to 6 is screwed with a pulling bolt (10) from its body (13) to a thin drawn base end (15). Although the cap nut (17) to be fastened is directly welded and integrated, the mortise pin (P) is passed through the cap nut (17) by the final turning operation of the pulling bolt (10).
As long as the upright material (Y) can be strongly pulled into the receiving material (X) and tightly integrated with it,
As shown in the modified embodiment of FIG. 20, the fixed length (L) of the tenon pin (P) is substantially equal to the depth (G) of the tenon pin receiving groove (11) opened in the vertical member (Y). It is equally dimensioned, and only the base end facing the lower surface (the cut surface) of the upright (Y) is finely drawn, and a separate adapter bolt (22) is inserted into the thin base end with the screw shaft. Part (22
b) is formed so as to function as the screwed base end portion (15) by being integrated by welding into a plug-in reinforcing state in which the lower end (Y) of the upright material (Y) projects from the lower surface (the cut end surface). Further, the separate cap nut (17) may be screwed and fastened to the screw shaft portion (22b) of the adapter bolt (22). (22a) is a large-diameter head portion of the adapter bolt (22) which is locked at a boundary position between the body portion (13) and the narrow base end of the tenon pin (P).

Further, the installation of the adapter bolt (22) is omitted, and the welding of the cap nut (17) to the screwed base end (15) as in the first embodiment is also omitted. As shown in another modified embodiment, the male screw (1) of the screwed proximal end (15) of the tenon pin (P) is used.
6) The separate cap nut (17) may simply be screwed and fastened. Further, it is conceivable that the cap nut (17) is welded and integrated with the screw shaft (10b) of the pulling bolt (10) in advance.

In any case, the cap nut (17) and the screw shaft (10b) of the pulling bolt (10) are screwed into the pulling bolt receiving through hole (9) opened in the receiving member (X). It will be concluded jointly.

In the first embodiment shown in FIGS.
