RAIL LAYING STRUCTURE AND RAIL LAYING METHOD
To provide a rail laying structure and a rail laying method which can suppress formation of a step and can be laid such that the rail alignment is appropriate.SOLUTION: Since a rail 10 has a circular cross section in a direction perpendicular to the longer direction, a surface of an exposed part projecting upward at the height of a ground surface 5 is a curved surface having a circular cross-section outer periphery in a direction perpendicular to the longer direction of the rail 10, forming a smooth curved surface. Further, a recess 16 for a flange of a wheel to pass through has such a shape that the outer periphery of the cross section is formed on both sides of a lowermost part 50 having an arc-shaped curved surface. Therefore, unlike those normally used having a rectangular cross-section, no steps are formed at which the height is discontinuous in the vertical direction, and having a barrier-free structure allows a user to pass by without any obstacles when wheels of a wheelchair pass over.SELECTED DRAWING: Figure 9
【課題】段差の形成を抑制することができるとともに、レールの位置合わせが適正となるように敷設することが可能なレールの敷設構造と、レールの敷設方法を提供する。【解決手段】レール１０は、長手方向に対して垂直な方向の断面が円形であるため、地盤面５の高さから上側に出ている露出部分の表面は、レール１０の長手方向に対して垂直な方向の断面外周が円弧状である曲面となり、滑らかな曲面が形成される。また、車輪の鍔が通るための窪み１６は、最下部５０を挟んで、その両側に断面外周が円弧状の曲面が形成された形状となっている。そのため、通常使用される断面が矩形状のレールを敷設したものと異なり、上下方向に高さが不連続となる段差が一切形成されず、車椅子車輪が乗り越える際に障害とならずに自力で通行できるバリアフリーの構造となる。【選択図】図９
