In this level adjustment, for example, while measuring the horizontality of the floor member 13, for example, the male screw members 29 of the three level adjusting means 25 arranged on the floor member 13 are rotated, and the tips of the male screw members 29 are rotated. This is performed by projecting a small amount toward the building beam 11 side.
As described above, by finally adjusting the levels at three places, the level adjustment can be easily and reliably performed.
[0029]
Next, an adhesive 23 is filled in an adhesive filling space 21 formed by the sheet member 17, the wall member 19, and the lower surface of the floor member 13.
The filling of the adhesive 23 is performed by inserting a tip of a hose, a pipe, or the like into a filling hole 13a formed in the floor member 13 and pouring the adhesive 23 from the other end of the hose, the pipe, or the like.
[0030]
The filling of the adhesive 23 is performed by measuring the filling amount of the adhesive 23 into the adhesive filling space 21 by inserting a rod member or the like into the filling hole 13a.
Next, after the adhesive 23 is completely cured, the floor member 13 is fixed to the building beam 11 by the fixing means 26.
In this embodiment, first, as shown in FIG. 6, a male screw portion 29 a formed on the upper side of the vertical member 29 is screwed to a female screw member 33 arranged on the lower surface of the floor member 13, and a nut 35 Vertical members 29 are fixed to both sides of the building beam 11.
[0031]
Next, through holes 31a formed on both sides of the horizontal member 31 are fitted into the lower male screw portion 29b of the vertical member 29, and a nut 37 is screwed into the male screw portion 29b from below the horizontal member 31. Is done.
The horizontal member 31 is pressed against the lower surface of the building beam 11 by the rotation of the nut 37, and the floor member 13 is firmly fixed to the building beam 11.

In the above-described high-rigid floor installation structure, since the sheet member 17 is disposed on the upper surface of the building beam 11, even when the adhesive 23 is filled between the building beam 11 and the floor member 13, the adhesive 23 remains in the building beam. Thus, the floor member 13 can be easily and reliably removed from the building beam 11.
Further, since the wall members 19 having elasticity are arranged along both sides in the longitudinal direction of the upper surface of the building beam 11, when the floor member 13 is placed on the upper surface of the wall member 19, the wall member 19 is elastically deformed and the sheet member 17 is deformed. Since the adhesive filling space 21 in a closed state is formed by the lower surface of the wall member 19 and the floor member 13, the adhesive filling space 21 can be reliably filled with the adhesive 23.
[0033]
Further, in the above-described structure for installing a high-rigidity floor, since the floor member 13 is fixed to the building beam 11 by the fixing means 26, it is possible to reliably prevent the floor member 13 from moving from the building beam 11 due to vibration such as an earthquake.

In the above-described embodiment, an example is described in which the sheet member 17 uses the adhesive tape 39 such as a vinyl tape or a gum tape. However, the present invention is not limited to such an embodiment. It is only necessary to prevent direct adhesion to the beam 11 side or adhesion on the entire surface, and for example, a sheet such as a Teflon (registered trademark) sheet can be used.
[0036]
When a sheet having no adhesiveness is used on the building beam 11 side, the sheet is placed on the upper surface 11a of the building beam 11 with a slight gap, and the adhesive strength of the adhesive 23 is adjusted at the sheet portion. A configuration is adopted in which the shear stress is weakened at this portion by weakening. Further, in the above-described embodiment, an example in which an elastic body made of rubber is used for the wall member 19 has been described.
