PRECAST CONCRETE SLAB AND ITS CONSTRUCTION METHOD
To provide a precast concrete slab that improves the workability on site and can secure quality of the junction even under the influence of distortion or vibration.SOLUTION: A precast concrete slab consists of a main body 2 and a joint structure 1 arranged at least at a part of the peripheral surface of the main body, and is configured in a way described hereinafter. The aforesaid joint structure 1 consists of: an upper joint structure 11 that comprises an upper joint top face, an upper joint bottom face, a first vertical face and a second vertical face of the upper joint, an upper joint slope, and upper protrusion reinforcement bars 311; and/or a lower joint structure 12 that comprises a lower joint top face, a lower joint bottom face, a first vertical face and a second vertical face of the lower joint, a lower joint slope, and lower protrusion reinforcement bars 321. When one side of a joint is the aforesaid upper joint structure 11, the other side of the joint is arranged to be the aforesaid lower joint structure 12. Both the aforesaid upper/lower protrusion reinforcement bars 311/321 have tips with male screw shape, comprising upper/lower anchor plates 312/322 and upper/lower nuts 313/323. Upper/lower protrusion-bar-housing parts that can accommodate the protrusion reinforcement bars 311/321 are included. Inserts capable of adjusting the protrusion length are included. Upper/lower notches continuous to the aforesaid upper/lower protrusion-bar-housing parts are included.SELECTED DRAWING: Figure 1
【課題】現場での作業性を向上するとともに、変形や振動の影響下においても接合部の品質を確保できる、プレキャストコンクリート版を提供する。【解決手段】本体２とその周面の少なくとも一部に設けた継手構造１とを有し、前記継手構造１は上継手上面と上継手下面と上継手第一・第二鉛直面と上継手傾斜面と上突出筋３１１とを有する上継手構造１１及び／又は下継手上面と下継手下面と下継手第一・第二鉛直面と下継手傾斜面と下突出筋３２１とを有する下継手構造１２を有し、一方が前記上継手構造１１のとき他方を前記下継手構造１２により構成し、前記上下突出筋３１１・３２１はいずれも先端が雄ネジ状で上下定着板３１２・３２２と上下ナット３１３・３２３とを有し、突出筋３１１・３２１を収容可能な上下突出筋格納部を有し、突設長が調整可能なインサートを有し、前記上下突出筋格納部と連続する上下切り欠きを有する、プレキャストコンクリート版。【選択図】図１
