GUIDE MEMBER FOR JOINING CONCRETE PRECAST MEMBERS AND JOINING METHOD OF CONCRETE PRECAST MEMBER
To make it possible to quickly align positions without deteriorating quality and safely perform a work.SOLUTION: Female joints 3 each consisting of a groove-shaped engaging portion 6 having a groove-shaped cross section in a plan view and a female joint anchor portion 7 extending behind it, are buried at predetermined intervals in a horizontal direction, with a vertical groove 5 in a state of facing the outside, on a joint end face of a precast floor slab 1A on one side, and male joints 4 each consisting of a male joint anchor portion 9 whose tip is formed to protrude outside and a fixing portion 8 capable of being inserted into the groove-shaped engaging portion 6 provided at the tip, are buried at predetermined intervals in the horizontal direction on a joint end face of a precast floor slab 1B on the other side. Guide members are constituted such that a concave guide member 21 provided with a guide groove 23 extending along a vertical direction, and a convex guide member 22 provided with a guide protrusion 24 engaging with the guide groove 23 and capable of moving along the guide groove 23 are arranged facing each other on a position where the female joints 3 and the male joints 4 are not arranged among the joint end faces of the precast floor slabs 1A, 1B.SELECTED DRAWING: Figure 12
【課題】品質を低下させることなく、迅速に位置合わせできるとともに、安全に作業を行うことができるようにする。【解決手段】一方側のプレキャスト床版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床版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。ガイド部材は、プレキャスト床版1A、1Bの接合端面のうち、雌継手３及び雄継手４が配置されない位置に、上下方向に沿って延びるガイド溝23を備えた凹型ガイド部材21と、ガイド溝23に係合しガイド溝23に沿って移動可能なガイド凸部24を備えた凸型ガイド部材22とが、対向配置して構成される。【選択図】図１２
