筋工法を提供することを目的とするものである。[Detailed description of the invention] The present invention relates to a foundation reinforcement construction method when constructing the foundation of a building, and the strength of the intersection between the reinforcing bar and the anchor bolt is high, and the reinforcement is placed near the intersection. This method allows you to place anchor bolts in a concentrated manner in areas of the foundation that require particular strength, without the risk of cracks in the concrete being built or corrosion of the reinforcing steel, and with a simple operation. The purpose is to provide a foundation reinforcement construction method that can easily partially improve the strength of the steel.
従来、第４図に示すように、建築物の基礎Ａを構築する
に際して配筋を行う基礎配筋工法において、鉄筋１とア
ンカーボルト２の中心線が同一線上に来て両者が衝突す
る。Conventionally, as shown in FIG. 4, in a foundation reinforcement construction method in which reinforcement is arranged when constructing a foundation A of a building, the center lines of reinforcing bars 1 and anchor bolts 2 are on the same line, and the two collide.
所謂、鉄筋１とアンカーボルト２との交叉部Ｂにおいて
は、鉄筋１を曲げ加工しアンカ−ボルト２外周胴部を迂
回させて配筋して基礎配筋を行っている。At the so-called intersection B between the reinforcing bar 1 and the anchor bolt 2, basic reinforcement is arranged by bending the reinforcing bar 1 and bypassing the outer peripheral body of the anchor bolt 2.

する部分に集中的に配筋して、基礎の強度を部分的に向
上させることも容易に行えないと云う欠点があった。However, when the reinforcing bars 1 are arranged by bending them as described above, the tensile force and other stresses acting on the beams of the building cause deformation in the bent parts of the reinforcing bars 1, resulting in a decrease in strength. , and the concrete to be cast near the bent part (the intersection B of the reinforcing bar 1 and the anchor bolt 2) due to the deformation.
In addition, when reinforcing the anchor bolts 2, as mentioned above, it is important to note that cracks may occur in the J-t and the reinforcing bars 1 may corrode due to the cracks. , since the reinforcing bars 1 must be bent, it is not easy to place anchor bolts in areas of the foundation that require particular strength to partially improve the strength of the foundation. There was a drawback.
本発明は、上記従来の基礎配筋工法の欠点を改良するた
めに為されたものである。The present invention was made in order to improve the drawbacks of the conventional foundation reinforcement construction method.
以下、本発明を図面に基いて詳細に説明する。Hereinafter, the present invention will be explained in detail based on the drawings.

。In the present invention, for example, as shown in FIGS. 1 to 3, at the intersection B of the reinforcing bar 1 and the anchor bolt 2, as shown in FIG. A reinforcing bar through hole 4 is formed in the peripheral body part 3 that can be rolled flat, and the reinforcing bar 1 is passed through the reinforcing bar through hole 4 of the anchor bolt 2, as shown in FIGS. 2 and 3, and the anchor bolt is inserted into the reinforcing bar 1. This invention relates to a foundation reinforcement construction method characterized in that the foundation reinforcement is placed by attaching the base plate 2 in a slidable manner and welding and reinforcing the penetrating portion as necessary.
尚、上記本発明の基礎配筋工法にて基礎配筋を行った後
においては、該基礎配筋の周辺部にコンクリートを打設
して基礎を構築する。Incidentally, after the foundation reinforcement has been arranged using the foundation reinforcement arrangement method of the present invention, concrete is poured around the foundation reinforcement to construct the foundation.

するものではない。Further, in the above-mentioned present invention, as shown in FIG. 3, an embodiment is illustrated in which the reinforcing bar 1 and the anchor bolt 2 intersect at a straight part and a part of a corner. It goes without saying that foundation reinforcement can be arranged in the same manner as described above at the intersection of the foundation, and this does not depart from the scope of the present invention.

る。As described above, the present invention forms a reinforcing bar through hole in the circumferential body of the anchor bolt at the intersection of the reinforcing bar and the anchor bolt, and also allows the reinforcing bar to pass through the reinforcing bar through hole of the anchor bolt, and attaches the anchor bolt to the reinforcing bar. Since the foundation reinforcement is arranged by attaching it so that it can slide freely, it is possible to arrange the reinforcement smoothly and firmly at the intersection of the reinforcing bars and the anchor bolt without bending the reinforcing bars and bypassing the outer circumferential body of the anchor bolt. However, unlike conventional methods, deformation occurs in the bent part of the reinforcing bars, resulting in a decrease in strength, and cracks occur in the concrete placed near the bent part due to the deformation, which leads to corrosion of the reinforcing bars. There is no risk of this occurring, and the reinforcement position of the reinforcing bars is regulated by the reinforcing bar through holes of the anchor bolts, and the tilting of the anchor bolts can be prevented by the reinforcing bars, so the reinforcing bars and anchor bolts can be kept in good condition. It has the advantage of being able to hold the reinforcing bars in place and place them accurately.Also, the anchor bolts can be slid freely using the reinforcing bars as guides, allowing the anchor bolts to be placed in a concentrated manner in areas of the foundation that require particular strength. Therefore, it is easy to partially improve the strength of the foundation.
