JOINT STRUCTURE FOR CONCRETE PRECAST MEMBER
To significantly shorten a construction period, and to increase the placement interval of joints to facilitate quality control during erection by making it possible to increase the engagement area per joint.SOLUTION: A female joint 3 consisting of a groove-type engaging part 6 having a groove-shaped cross section in a plan view and a female joint anchor part 7 extending rearward thereof is embedded in a joint end surface of a precast member 1A on one side with a joint 2 as a boundary at prescribed intervals in the horizontal direction with a vertical groove 5 facing the outside. A male joint 4 consisting of a male joint anchor part 9 having a tip formed so as to project outward and a fixing part 8 that is provided at the tip of the male joint anchor part and can be inserted into the groove-type engaging part 6 is embedded in a joint end surface of a precast member 1B on the other side at prescribed intervals in the horizontal direction. The groove-type engaging part 6 is formed in a vertically long shape that is long in the vertical direction. The fixing part 8 is formed in a vertically long shape that is long in the vertical direction. The male joint anchor part 9 is formed in a flat plate shape along a plane in the vertical direction.SELECTED DRAWING: Figure 5
【課題】大幅な工期短縮が図れるようにするとともに、継手１箇所当たりの係合面積を増加することにより、継手の配置間隔を大きくして架設時の精度管理を容易化する。【解決手段】継手部２を境に一方側のプレキャスト部材１Ａの接合端面に、水平方向に所定の間隔で、平面視で溝型断面からなる溝型係合部６と、その後方に延びる雌継手アンカー部７とからなる雌継手３が縦溝５を外部に臨ませた状態で埋設され、他方側のプレキャスト部材１Ｂの接合端面に、水平方向に所定の間隔で、先端が外部に突出形成された雄継手アンカー部９と、その先端に備えられた溝型係合部６内に挿入可能な定着部８とからなる雄継手４が埋設されている。溝型係合部６が上下方向に長い縦長の形状で形成されるとともに、定着部８が上下方向に長い縦長の形状で形成され、かつ雄継手アンカー部９が上下方向平面に沿った平板形状で形成されている。【選択図】図５
