一体的に連結する。A method of constructing a foundation of the present invention is to install a precast concrete column base having a loose hole for inserting a beam reinforcing bar on a footing and projecting the reinforcing bar of a precast concrete foundation beam. And while joining the rebar inserted through the loose hole, after positioning the rebar to fix the rebar to the column base of precast concrete by filling the loose hole with grout material, concrete at the joint between the column base and the foundation beam It is cast and connected integrally.

アンカーボルト６が突設してある。EXAMPLE In FIG. 1, a foundation pile 1 is buried in the ground A, and a footing 2 is formed on the top of the foundation pile 1. The column base 3 and the foundation beam 4 are each made of precast concrete, and a horizontal reinforcing bar 5 is projectingly provided in the connecting direction. An anchor bolt 6 is projectingly provided on the top of the column base 3.

枠８を配しコンクリートを打設して一体的に連結する。The column base 3 is installed on the footing 2 using mortar or the like. Next, the foundation beam 4 is arranged between the column bases 3, both of the reinforcing bars 5 are joined by a mechanical joint using a sleeve 7, etc., and the formwork 8 is arranged on both sides of the column base 3 and the foundation beam 4 joint B. Concrete is poured and connected integrally.

ラウト材の充填によって定着するので施工性がよい。EFFECTS OF THE INVENTION The present invention having the above-described structure divides the foundation into column pedestals and foundation beams, each made of precast concrete, and at the site, the horizontal reinforcing bars protruding from each are joined and the concrete is placed only at the joints. Therefore, the construction is easy, and the curing of the concrete is small, which shortens the construction period and saves labor. In particular, the horizontal rebar projecting from the column base is inserted into the loose hole and is fixed by filling the grout material after positioning the horizontal rebar, so workability is good.
