[0002]

2. Description of the Related Art Conventionally, the foundation of a wooden house or the like is a foundation formed of concrete, a plurality of anchor bolts for fixing a foundation body buried at a predetermined interval on the foundation, and a plurality of bolts. An anchor bolt is inserted, a base body having a bolt insertion hole formed therein, and a fixing nut screwed into the anchor bolt to fasten and fix the base body. After assembling the girder and girder, the upper building was constructed, and then the roof was attached to the upper part of the upper building to construct the building.

[0003]

[Problems to be Solved by the Invention] In the conventional construction of a building, the upper surface of the foundation must be machined so as to be horizontal. There is a method of carefully patting the filled mortar with a trowel or a method using a level mortar, but the former can not obtain an accurate horizontal surface, it takes time to work, and it takes a long time to cure There were drawbacks. In the latter method, the surface is processed into a horizontal surface by surface tension. However, surface tension like water cannot be obtained, an accurate horizontal surface cannot be obtained, and it takes a long time to cure. In addition, the connection strength between the base body of the base and the upper building installed on the top of the base body is weak, and there is a disadvantage that sufficient earthquake resistance cannot be obtained.

The present invention has been made in view of the above-mentioned conventional drawbacks,
The base can be installed on an accurate horizontal surface in a short time with simple work, and the base and the upper building are firmly connected to each other. It aims to provide a construction method.
