Abstract

PROBLEM TO BE SOLVED: To improve working efficiency by separately providing a bolt projecting only height enough to fix an anchor bolt buried in a sill on a sill reinforcing fitting and fixed on a floor and a wall. SOLUTION: The base part 21 of an anchor bolt 2 is buried in the concrete foundation 1 of a building, and the other part is projected on the foundation 1 in the form of an erection part 22. In addition, a sill reinforcing fitting 5 is previously fitted to a channel-like steel-made sill 3. The anchor bolt 2 is inserted in the bolt hole of the lower plate-like part of the sill 3, and the sill 3 and the fitting 5 are lowered to be mounted on the foundation 1. The erection part 22 of the anchor bolt 2 is inserted in the bolt holes of the sill 3 and the fitting to be tightened by nuts 54, 55. A bolt 56 attached to the upper plate-like part of the sill 3 is inserted in a structural plywood 6 and the lower frame 7 of a wall. Furthermore, a stud 8 is arranged on the lower frame 7, and a hole-down fitting 9 is inserted in the bolt 56 to be arranged and fixed on the lower frame 7. Thereby working efficiency can be improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, reference numeral 1 denotes a concrete foundation of a building, and an anchor bolt 2 having a diameter of 16 mm.
Is buried, and the other part is erected on the concrete foundation 1 in the form of a standing part 22. A channel-like steel base (side joist) 3 is inserted through the upright portion 22 via a spacer 4.

That is, as shown in FIG. 2, a channel-shaped steel base having an upper plate-shaped portion 31 and a lower plate-shaped portion 32 and a connecting wall 33 connecting the upper plate-shaped portion 31 and the lower plate-shaped portion 32. Invite 3 A bolt hole 31 ′ and a bolt hole 32 ′ are formed in the upper plate-shaped portion 31 and the lower plate-shaped portion 33 so as to be positioned in advance, and the anchor bolt 2 is inserted into the bolt hole 32 ′ of the lower plate-shaped portion 32. Then, the channel-shaped steel base 3 is lowered and placed on the foundation 1 via the spacer 4.

Actually, as shown in FIGS. 3 and 4, a base reinforcing metal 5 is previously fitted into the channel-shaped steel base 3. The base reinforcing hardware 5 includes a ceiling part 51 and a floor part 5.
The ceiling 51 and the floor 52 are formed with bolt holes 52 'positioned with respect to each other. Then, while positioning the bolt holes 52 'of the base reinforcing metal 5 and the bolt holes'32' of the channel-like steel base up and down, the former surrounds the latter in the channel-like steel base 3 so that the latter surrounds the latter. To fit.

In this state, the channel-shaped steel base 3 and the base reinforcing hardware 5 are lowered, and the upright portions 22 of the anchor bolts 1 are raised.
Are inserted through the bolt holes 32 ′ and 52 ′ and tightened by the washers 53 and the nuts 54 and 55. On the other hand, the bolt hole 51 'of the ceiling part 51 of the base reinforcing metal 5 and the bolt hole 31' of the upper plate-shaped part 31 of the channel-shaped steel base 3 are positioned so that the ceiling part 51 of the reinforcing metal fitting 5 and the channel-shaped steel A bolt 56 is inserted from the upper plate-shaped portion 31 of the base 3 through a washer 57 and tightened with a nut 58.

Then, as shown in FIG. 6, a structural plywood 6 having a bolt hole 6 'thereon is made to face the channel-like steel base 3 and the base reinforcing hardware 5, and then a bolt 56 is inserted into the bolt hole 6'. 6 'and inserted. In this case, an anti-vibration effect can be expected by appropriately applying the adhesive B on the upper plate-like portion 31 of the channel-like steel base 3 as shown in the figure.

Further, as shown in FIG.
The lower frame 7 of the wall and the two studs 8 standing upright facing the lower frame 7 from the back. It goes without saying that a bolt hole 7 ′ through which the bolt is inserted is formed in the lower wall frame 7. Then, as shown in FIG.
Are inserted through the bolt holes ′, and the lower frame 7 and the studs 8 are integrally dropped on the plywood 6 and placed.

Further, a horizontal fixing portion 91, an upright wall 92 vertically erected on the horizontal fixing portion 91, and a pair of reinforcing members 93 between the horizontal fixing portion 91 and the upright wall 92 are provided. The hole-down metal fittings facing the lower frame. The horizontal fixing portion 91 has a bolt hole 91 ′. Then, the hole down metal is lowered and the bolt hole 91 ′ is formed.
Then, the horizontal fixing portion 91 is fixed to the stud 8 at a level separated from the lower frame by a known method such as a metal fitting screw. Then, a double nut 57 is attached to the bolt 56 from above the horizontal fixing portion 91.
And fix it.

The foundation, base,
The floor and wall structures are shown in FIG. As is clear from the figure,
The anchor bolt 2 buried in the concrete foundation 1 has its upper part erected from the concrete foundation 1, but protrudes only at a height necessary for being fixed by the reinforcing metal 5.

FIG. 11 shows an embodiment different from that described above, in which anchor bolts 2 embedded in a foundation 1 are shown.
Is erected upward via a wooden base W. FIGS. 12 and 13 are the same as the first embodiment in that anchor bolts are erected upwards via appropriately assembled color steel plates 32 instead of wooden bases.

[0018]

As described in detail above, in the work of fixing the foundation, foundation, floor, wall, etc. of a building, the upper part of the anchor bolts with the lower part buried in the base is erected high on the base. Since it is not performed, the foundation, the base, the floor, the wall, etc. can be fixed efficiently, and it is safe for the operator.
