共々抜け易い。However, if the anchor bolts are to be immediately installed at the time of concrete placement, considerable accuracy is required. Generally, a concave portion is provided in the foundation concrete, and the anchor bolt is later placed in the concave portion. It is difficult to set the anchor to the reinforcing bar in terms of position and level, and it is often difficult to set the anchor without engaging the reinforcing bar. It can also be done. In addition, the concrete cannot be roughened when the void is removed, and the anchors are easily removed.

The point is to provide a method.

である。To achieve the above object, according to the anchor bolt fixing method of the present invention,
A net iron cone whose diameter gradually increases as it goes down, and whose top surface is open, is buried in the foundation casting concrete, and the mesh iron cone is filled with non-shrink mortar and consolidated.
A J-type anchor bolt is inserted and buried in the mortar.

にＪ型アンカー４を挿入する。DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings showing the most preferred embodiments of the present invention. 1 has an opening 1a whose diameter gradually increases toward the bottom and only on the top surface.
A mesh iron cone having the mesh iron cone 1 installed in the foundation concrete 2 and the mesh iron cone 1
Then, a compacted mortar 3 made of non-shrinkable mortar is loaded and compacted through the top opening 1a, and a J-type anchor 4 is inserted into the compacted non-shrinkable mortar 3.
【０００７】従って前記の方法によれば前記網鉄製円錐

定着される。Therefore, according to the above-mentioned method, the compacted non-shrinkable mortar 3 loaded in the mesh iron cone 1 is tightly integrated with the foundation concrete 2 via the mesh of the mesh iron cone 1. By inserting and embedding the J-type anchor 4 in the consolidation non-shrinkable mortar 3, the J-type anchor 4 is firmly fixed to the foundation concrete 2 without engaging the J-type anchor 4 with the foundation rebar.

が目荒し状態となる。Further, since the net iron cone 1 is formed in a conical shape whose diameter gradually increases as it goes down, the post-cast concrete together with the J-type anchor 4 does not come off from the base concrete. In addition, since the cone 1 has a mesh shape, the concrete filled in the cone 1 protrudes from the mesh, and the anchor attachment portion in the foundation concrete is roughened.

て基礎コンクリートが目荒し状態となる。According to the present invention, as described above, the mesh made of mesh iron whose diameter gradually increases toward the lower portion and whose top surface is open is buried in the foundation concrete, so that the cone is filled. The post-cast concrete adhered well to the base concrete, and the J-type anchor inserted into the post-cast consolidation non-shrink mortar filled in the cone adhered well to the base concrete even if it was not fixed to the base rebar. When the mold anchor has a structure that is difficult to come off, when removing the mesh iron conical material,
The foundation concrete is roughened by the concrete projecting from the mesh of the mesh iron conical material.
