。[Detailed Description of the Invention] The present invention relates to a foundation reinforcement construction method when constructing the foundation of a building, in which the strength of the intersection between the reinforcing bar and the anchor bolt is high, and the reinforcement is placed near the intersection. The purpose of the present invention is to provide a foundation reinforcement construction method that does not cause cracks in concrete or corrosion of reinforcing bars.

迂回させて配筋して基礎配筋を行っている。Conventionally, as shown in Fig. 3, in the foundation reinforcement construction method in which reinforcement is arranged when constructing the foundation A of a building, the center lines of the reinforcing bars 1 and anchor bolts 2 are on the same line and the two collide. At the intersection B between the reinforcing bars 1 and the anchor bolts 2, the reinforcing bars 1 are bent and the reinforcement is placed around the outer periphery of the anchor bolts 2 to provide basic reinforcement.

に関するものである。The present invention, for example, as shown in FIGS. 1 and 2,
The reinforcing bar 1 is bent at the intersection B of the reinforcing bar 1 and the anchor bolt 2, and the reinforcement is placed around the outer periphery of the anchor bolt 2, and the anchor bolt through hole 3 is driven into the intersection B by a metal piece ( For example, a plate 4 made of iron (for example, a piece of iron) is disposed, and a bent portion 5 of the reinforcing bar 1 is placed on the plate 4.
The present invention relates to a foundation reinforcement construction method characterized in that the foundation reinforcement is arranged by welding the plates 4 in contact with each other and attaching the anchor bolts 2 through the anchor bolt through holes 3 of the plates 4.

明の範囲を逸脱するものではない。Further, in the above-mentioned present invention, as shown in FIGS. 1 and 2, an example has been exemplified in which the reinforcing bar 1 and the anchor bolt 2 intersect at a straight portion and a part of a corner. It goes without saying that foundation reinforcement can be arranged in the same manner as described above at intersections of cross-shaped, T-shaped, etc. foundations, and this does not depart from the scope of the present invention.

Furthermore, the bending parts of the reinforcing bars are brought into contact with the plate and welded, and the basic reinforcement is arranged so that the anchor bolts are inserted through the anchor bolt through holes of the plate, so that the bending of the reinforcing bars is prevented. Deformation of the processed part can be prevented by the plate welded to the bent part, and the intersection between the reinforcing bar and the anchor bolt can be reinforced with this plate, so the strength of the intersection between the reinforcing bar and the anchor bolt is excellent. Since deformation of the bent portion of the reinforcing bars can be prevented, there is no risk of cracking in the concrete placed near the intersection of the reinforcing bars and the anchor bolts, and corrosion of the reinforcing bars due to cracks can be prevented. There is no possibility that this will occur.
