Description of the Related Art Conventionally, a floor beam of a building is fastened with anchor bolts buried and erected in a concrete foundation to transmit the load of the entire building to the concrete foundation, and the building is firmly supported by the concrete foundation. . The anchor bolt is attached to the concrete part with its lower end curved,
Strength is maintained to withstand vertical and horizontal forces. From the viewpoint of structural strength, a main reinforcement portion erected in parallel with the anchor bolt is buried in the base portion at the lower end portion and near the center portion from the viewpoint of structural strength. However, the thickness of the concrete covering the anchor bolt in the horizontal direction is not necessarily symmetrical, and one side may be thick and the other side may be thin. For this reason, there is a difference in the covering thickness around the anchor bolt at the upper end of the foundation.

の付着強度に有効に作用している。[0002] When the concrete foundation is laid at the base portion at the lower end portion, the concrete has a sufficient adhesive force against normal force. However, when a horizontal force such as an earthquake rolls, a horizontal load tends to concentrate around the anchor bolt. As described in Japanese Patent Application Laid-Open No. 60-175650, a method of using a porous body as a reinforcing material for basic concrete has been known as a reinforcing structure, and this effectively affects the adhesive strength of the entire concrete foundation.

生しやすいと言った問題がある。However, as described above, even when around the anchor bolts, there is no reinforcing bar at the upper end of the foundation. There is a problem that cracks are likely to occur when the covering thickness is small due to the horizontal force acting intensively around the anchor bolt which is a part.
