後、次の柱の接続作業に移る。(Prior Art) The present applicant has proposed a reinforcing bar joint shown in FIG. This is done by fixing the sleeves S and Sa, which are joints, to the ends of the reinforcing bars R and Ra to be connected, and then tightening the bolt B, which has been previously screwed into one of the sleeves S, by turning the double nut N attached to this bolt. The two reinforcing bars are joined by feeding one end of the bolt into the other sleeve Sa as shown by the chain line, and stopping feeding when it has been inserted a predetermined amount. T and Ta are tapered portions formed on the outer periphery of each sleeve S and Sa. When using such joints to, for example, erect prefabricated reinforcing bars, the upper column is hoisted by a crane, all the reinforcing bar joints are connected while the column is suspended, and after the work is completed, the next step is carried out. Move on to the pillar connection work.

作業が迅速かつ容易に行えない。 As a method for determining the distance between opposing joints, for example, by applying the tightening torque imparting device for reinforcing bar connection fittings described in Japanese Utility Model Application Publication No. 61-67348, a hydraulic cylinder and chuck fittings provided on both sides of this hydraulic cylinder are used. It is also conceivable to hold each chuck fitting in each sleeve and adjust the stroke of the hydraulic cylinder to provide the joint spacing. however,
In the method using hydraulic cylinders, since the hydraulic cylinders are located on the sides of the opposing sleeves, it is difficult to install and remove the hydraulic cylinders when the spacing between adjacent reinforcing bars is narrow, and it is difficult to install and remove the chuck fittings on top of that. It is very time consuming and the work to determine the spacing between joints cannot be done quickly and easily.

異なる鉄筋の接続作業に利用できて便利である。(Effects of the Invention) According to the present invention, reinforcing bars can be temporarily held by providing a cylindrical reinforcing bar holding part and a cylindrical joint spacing holding part, so crane work and reinforcing bar connection work can be separated. Therefore, the connection work can proceed independently of the crane work, making the connection work more efficient. Since the spacing between the joints can be maintained automatically at the same time as temporary fixing, the spacing between the joints can be established reliably and easily. Further, according to the present invention, the cylindrical joint spacing holding part is concentrically connected to the cylindrical reinforcing bar holding part, and the receiving part that comes into contact with the tapered part of the reinforcing bar joint is provided on the inner peripheral part of both holding parts. Therefore, the holding state of the reinforcing bar joint is such that both holding parts and the connected reinforcing bar are in a straight line, and even if the spacing between adjacent reinforcing bars is narrow, the work to create a gap between opposing joints can be performed smoothly. In this case, it is only necessary to insert one of the reinforcing bar joints into one of the holding parts, and there is no need for work such as attaching chuck fittings as in the conventional example, so the work of determining the joint spacing can be done easily and quickly. By connecting both holding parts in a separable manner via the spacing adjusting threaded part and female threaded part, the spacing between reinforcing bar joints can be adjusted, so one type of temporary holder can be used to connect reinforcing bars with different joint spacings. It is available and convenient.
