る。(Problems to be Solved by the Invention) However, reinforcing bar joints using couplers, etc. cannot be connected without rotating or moving the mutual reinforcing bars to be connected, and since a fairly heavy installation tool is used, handling is difficult. If there are variations in the distance between reinforcing bars, it is difficult to connect them, the length of the reinforcing bars shrinks during connection, and there are also limitations on the shape of the reinforcing bars.
また重ね継手の場合には鉄筋をユニツト化した
とき、相互の鉄筋が干渉したり、後付け鉄筋の配
筋等、残工事が多い。 In addition, in the case of lap joints, when the reinforcing bars are made into units, there are many cases where the reinforcing bars interfere with each other, and there is a lot of work left to be done, such as reinforcing bars to be installed later.

ユニツトの接合に適用される。(Effects of the Invention) According to the present invention, the joint steel plates are attached to the front and back sides of a pair of reinforcing bar units that are to be joined, straddling the end portions of the reinforcing bars placed opposite each other, and concrete is added between the two joint steel plates. Since the reinforcing bar units are joined by pouring the reinforcing bars, construction is simple, and it can be applied to joining all reinforcing bar units, regardless of the shape or diameter of the reinforcing bars.

が、総合的にはコストを低減しうるものである。 In addition, the joint steel plate serves as a connecting reinforcing bar, a formwork for joining concrete, and is also used as an embedded steel plate.Furthermore, according to the present invention, reinforcing bars of any shape can be used instead of threaded reinforcing bars, which have been commonly used in the past. Coupled with the fact that it can be used, although the joint steel plate itself is expensive, overall costs can be reduced.
