FIG. 5 is an enlarged perspective view showing a state in which the mold fitting 2 of the embedded bolt 1 is fixed to the metal foam 4, and an enlarged front view of the screw portion 26 of the embedded bolt 1. FIG. 6 is a side sectional view of the concrete foundation.

This will be described with reference to FIGS. 1, 2 and 3. FIG.
FIG. 2 illustrates a state in which the embedding bolt 1 is embedded in the upper part of the concrete foundation that does not interfere with the arrangement of the beam reinforcing unit U by the form fitting 2 of the embedding bolt 1. FIG. 3 shows a state before the concrete is poured into the concrete casting formwork and a state where the metal foam 4 is removed after the curing is completed in the formation of the concrete foundation. Buried bolt 1 buried in concrete foundation
In the case of the form fitting 2, the form fitting 2
Engage and fix to the upper end of metal foam 4 for foundation building
An engagement fixing surface is provided, and the engagement fixing surface is

And suspended in the form fitting 2
Is temporarily fixed with a nut 24, and the upper end of the
Can be combined with bolt holes of metal form 4 on mating surface
Bolt holes 22 and place them on metal form 4
A center scale 23 for performing precision is provided . The buried bolt 1 is fixed to a formwork fitting 2. The formwork fitting 2 is engaged and fixed to a metal foam 4 before casting concrete, casts concrete, and is removed after curing. A buried bolt 1 buried for large receiving and joist receiving is configured to protrude from the upper part.

FIG. 4 and FIG. 5 will be described. Formwork fitting 2
Is the magnet 3 for engaging and fixing to the metal form 4
And a bolt hole 22 that can be combined with a bolt hole of the metal form 4 in order to firmly fix the form fitting 2 to the metal form 4.
And a central scale 23 for precisely performing the arrangement. The embedded bolt 1 is fixed to the mold fitting 2 by a nut 24, and the projection 25 of the nut 24 is
It is necessary to completely bury the hole in the mold fitting 2. When removing the formwork fitting 2, remove the metal foam 4,
When the nut 24 is removed, the mold fitting 2 can be easily removed.

Referring to FIG. 6, the concrete foundation will be described. A groove for forming a concrete foundation is dug, a gravel 7 is put in the groove, and a discard concrete 8 is cast on the gravel 7. The support fitting 10 is placed on the upper surface of the disposal container 8, and the beam reinforcing unit U is placed on the support fitting 10. The supporting bracket 10 has a purpose of obtaining a space between the dumping concrete 8 and the beam reinforcing unit U, and also has a function of preventing water from permeating into the beam reinforcing unit U from between the dumping concrete 8 and the concrete foundation. -ing Metal foam support fittings 11 are placed on the left and right of the disposal container 8, and the left and right metal foam support fittings 11 are connected by a connecting plate 14. In addition, an adjusting screw 12 is provided below the metal foam supporting bracket 11, and the height of the metal foam supporting bracket 11 can be adjusted by the adjusting screw 12. The left and right metal foams 4 are placed on the upper surface of the metal foam support fitting 11, and the base frame 9 made of a synthetic resin plate is placed on the side of the upper surface of the metal foam support fitting 11 and placed.

With the above configuration, a concrete casting formwork is formed, concrete is cast, and cured, whereby the embedding bolt 1 is configured to be embedded, and a concrete foundation having a chamfered portion is formed. In the concrete foundation, a beam reinforcement unit U constituted by a beam reinforcement 16 and a hoop reinforcement 15 is configured to be buried in a substantially lower half position, and an upper reinforcement 17 and an anchor bolt 18 are provided in a portion near the upper half. It is arranged. The strength of the concrete foundation can be sufficiently obtained by calculation using the beam reinforcement unit U located below, and the upper part is reinforced by the upper reinforcement 17 and the anchor bolts 18 so that it can be vertically and horizontally caused by an earthquake or a typhoon. It is possible to fully support the force of.
