PRECAST FLOOR SLAB CONNECTION STRUCTURE, PRECAST FLOOR SLAB SYSTEM, AND BRIDGE STRUCTURE

PROBLEM TO BE SOLVED: To provide a precast floor slab connection structure allowing precast floor slabs to be easily connected with each other.SOLUTION: A precast floor slab connection structure 2 connects a first precast floor slab 10 and a second precast floor slab 20, which are formed into tabular shape and disposed in arrangement direction X that intersects a thickness direction Z. The precast floor slab connection structure comprises: a first convexity 15 having first inclined surfaces 15c, 15d, which project from a side face of the first precast floor slab and incline toward one side Z1 in the thickness direction with the closeness to one side Y1 in an intersecting direction Y that intersects in the thickness direction and the arrangement direction; and a second convexity 25 having second inclined surfaces 25c, 25d, which project from a side face of the second precast floor slab and incline along and contact the first inclined surface. Movement of the first convexity and the second convexity in a direction along the first inclined surface is restricted by static frictional force between the first inclined surface and the second inclined surface or a fixing strength applied on the first inclined surface and the second inclined surface.SELECTED DRAWING: Figure 3 【課題】プレキャスト床版同士を容易に接続できるプレキャスト床版の接続構造を提供する。【解決手段】板状に形成され、厚さ方向Ｚに交差する並び方向Ｘに並べて配置された第一プレキャスト床版１０と第二プレキャスト床版２０とを接続するプレキャスト床版の接続構造２であって、第一プレキャスト床版の側面から突出し、厚さ方向及び並び方向にそれぞれ交差する交差方向Ｙの一方側Ｙ１に向かうにしたがって厚さ方向の一方側Ｚ１に向かうように傾斜した第一傾斜面１５ｃ、１５ｄを有する第一凸部１５と、第二プレキャスト床版の側面から突出し、第一傾斜面に沿って傾斜するとともに第一傾斜面に接触する第二傾斜面２５ｃ、２５ｄを有する第二凸部２５と、を備え、第一凸部と第二凸部との第一傾斜面に沿う方向の移動が、第一傾斜面と第二傾斜面との間に作用する静止摩擦力、又は、第一傾斜面及び第二傾斜面に作用する固着力により規制される。【選択図】図３
