REINFORCED JOINT, REINFORCED STEEL ASSEMBLY AND PRECAST REINFORCED CONCRETE BODY
To provide a reinforced joint and a precast reinforced concrete body which can tolerate misalignment between connecting reinforcing bars and can be applied to precast reinforced concrete, and that can shorten a joint length while securing a connection strength, which is advantageous in design of reinforcement bars and handling of joint, and can reduce the amount of injected mortar and reduce cost.SOLUTION: Both or one joint part of a coupler 2 is formed in a filling cylinder part 2A, and a mortar 3 is filled in between a reinforcement bar 1 and the other. A forward-spreading part 11 is provided at a portion of the reinforcement bar 1 to be inserted into the filling cylindrical part 2A. The filling cylindrical part 2A has a narrowed shape which narrows as it reaches the tip end, and the cross-sectional area between the filling cylindrical part 2A and the forward-spreading part 11 of the reinforcement bar 1 decreases as it reaches the coupler end part.SELECTED DRAWING: Figure 1
【課題】接続する鉄筋相互の芯ずれが許容できて、プレキャスト鉄筋コンクリート体に適用でき、また接続強度を確保しながら、継手長さを短くできて、配筋の設計や継手の取扱上で有利となり、かつモルタル注入量が節減できてコスト低下が図れる鉄筋継手およびプレキャスト鉄筋コンクリート体を提供する。【解決手段】カプラー２の両方または一方の継手部が、充填筒部２Ａに形成され、鉄筋１との間にモルタル３が充填される。鉄筋１の充填筒部２Ａに挿入される部位に先広がり部１１を有する。充填筒部２Ａは、先端側に至るに従って狭まる絞り形状であり、かつ充填筒部２Ａと鉄筋１の先広がり部１１の間の断面積が、カプラー端部に至るに従って小さくなる。【選択図】図１
