2. Description of the Related Art Conventionally, as a method of burying anchor bolts in a concrete foundation when constructing various structures, various types of supports are used on discarded concrete.
A method has been adopted in which a bolt is supported, or an anchor bolt is tied to a reinforcing bar framed on a discarded concrete with an iron wire or the like, and then the frame concrete is cast.

[0003] In addition, it is conceivable that an anchor bolt is welded and supported to a reinforcing steel bar framed on the above-mentioned discarded concrete. However, depending on the nature of the construction, the anchor bolt is deteriorated and is prohibited.

[0004]

In the above-mentioned conventional anchor bolt supporting methods, all require skill to support the anchor bolt at a predetermined position including a height, and a predetermined interval is required in a wide place. Drilling a large number of anchor bolts required a great deal of time and effort.

[0005] Even after the anchor bolts have been supported, the anchors may be poured when the body concrete is subsequently poured.
In some cases, the bolt was moved and was not buried in a predetermined position. Therefore, in the construction requiring accuracy, it is often necessary to redo the construction and correct the work.

[0006] The present invention has been made in view of the above circumstances,
It is an object to provide a buried construction method along with facilitating faster burying operation thereby improving the buried precision economic anchor bolts.
