とができる。[0003] In order to obtain a sufficient connection strength between the screw rebars 1, it is necessary to set the screwing depth of each screw rebar 1 to the joint 2 to a predetermined amount or more. For this reason, conventionally, a marking 5 extending in the longitudinal direction with paint or the like is provided on the outer periphery of the screw reinforcing bar 1 at a position away from the distal end surface 1a. Distance D 1 of the between one end (the end closer to the front end surface 1a of the screw rebar 1) and the front end surface 1a of the screw reinforcing bar 1 of the marking 5 is equivalent to the necessary screwing depth. Distance D 2 between the other end and the distal end surface 1a of the screw rebar 1 marking 5 corresponds to the screwing depth prohibiting any further screwing. This distance D 2 is intended to ensure the necessary screwing depth of the screw rebar 1 counterparty. Therefore, if the grout material is injected in a state where both ends of the joint 2 are located at positions corresponding to the markings 5 of the two screw reinforcing bars 1, that is, a state where a sufficient screwing depth is secured, a sufficient connection strength can be secured. Further, in the inspection of the connection state performed later, the screwing depth of the screw reinforcing bar 1 can be confirmed from the positional relationship between the marking 5 and both ends of the joint 2.

o corresponds to a screwing depth that prohibits further screwing. This is for securing the necessary screwing depth of the screw reinforcing bar 1 of the other party. Also, one end of the attachment portion 21 of the jig 20 (the positioning portion 2)
A predetermined length La from the end on the second side) corresponds to a required screw length of the screw reinforcing bar 1. Therefore, in the screwed state of the screw reinforcing bar 1, the additional portion 21 of the jig 20 can be seen, and the end 10 a of the joint 10 is separated from the other end of the additional portion 21 of the jig 20 by a predetermined length Lb (Lb = Lo). If it is located in the range of -La), it means that the required screwing length is secured.

りと確認できる。After the screwing of the threaded reinforcing bar 1 is completed and the screwing depth is confirmed, a nozzle of an injector (not shown) is applied to the injection hole 12 to inject a grout material (not shown). As a result, the grout material passes through the injection hole 12 and fills the gap between the outer peripheral surface of the screw reinforcing bar 1 and the inner peripheral surface of the joint 10.
By the hardening of the grout material, the connection work of the pair of screw reinforcing bars 1 is completed. When inspecting the connection state at a later date, it is possible to clearly confirm that the required depth is secured by screwing the two threaded rebars 1 by looking at the attachment portion 21 of the jig 20.

The threaded reinforcing bar 1 may be screwed to the joint 10 as follows. That is, the joint 10 is screwed about one half to the one screw reinforcing bar 1. Next, the other threaded reinforcing bar 1 is arranged coaxially with the joint 10, and the threaded reinforcing bar 1 is turned to be screwed into the joint 10 by about half. Instead of injecting the grout material, a torque may be applied to the pair of threaded reinforcing bars 1 so that the end surfaces 1a thereof are strongly applied to each other. In this case, the jig 20 may be attached to only one screw reinforcing bar 1. Since the tip surfaces 1a of both the screw reinforcing bars 1 are in contact with each other, if the screwing depth of one of the screw reinforcing bars 1 is confirmed with this jig 20, the other screw reinforcing bars 1
This is because the screwing depth will be checked.

In the case where a U-shaped jig is used and the step of screwing the jig to the joint over the entire length is not included in the screwing, it is not necessary to attach the jig to the screw reinforcing bar with an adhesive. In this case, as the screw rebar is screwed into the joint, the jig also advances with the screw rebar via the positioning portion abutting on the distal end surface of the screw rebar. Further, the jig positioning portion may not be provided. In this case, only the attached portion is attached to the non-threaded portion of the screw reinforcing bar with an adhesive or the like. In this case, similarly to the above embodiment, the additional portion may extend from the distal end surface of the screw rebar by a length Lo (see FIG. 1), or the additional portion having the length Lb may be extended from the distal end of the screw rebar. They may be mounted apart by a predetermined length La. The jig may be constituted by a colored adhesive tape.
