PROBLEM TO BE SOLVED: To provide a portable slope which is light in weight and easy to carry, can be easily manufactured at a low cost in an optimum size with excellent workability, is excellent in a fixing performance, is not easily broken by a high impact resistant performance of a slope edge part and a derailing prevention wall, and has an excellent repair performance.SOLUTION: A portable slope includes at least two pieces of plywood for which plate materials made of fiber reinforced plastic (FRP) are bonded to both front and back surfaces of a square core material composed of a foamable resin. The pieces of plywood have tapered structures 4 and 5 for dissolving the level difference of the pieces of plywood themselves at respective upper and lower ends in a passing direction and have a structure for which an outer side face to the passing direction is fitted by a frame member 9, two or more pieces of plywood are arranged side by side with respect to the passing direction, opposed side faces of the pieces of plywood are connected by a sheet material 6, and the pieces of plywood are made foldable so as to overlap with each other. Further, an impact absorber 7 is mounted on the outer periphery of a part to be fitted to the tapered structure of the plywood, in a frame member.COPYRIGHT: (C)2013,JPO&INPIT【課題】軽量で持ち運びが容易であり、加工性が良く最適なサイズを容易かつ安価に製造でき、固定性能に秀で、スロープ縁部及び脱輪防止壁の高い耐衝撃性能により破損が生じにくく、優れた補修性能を有する携帯用スロープを提供する。【解決手段】発泡性樹脂からなる方形の芯材の表裏両面に、繊維強化プラスチック(FRP)製の板材を接着した少なくとも2枚以上の合板からなり、合板は、通行方向上下端それぞれに合板自身の段差を解消するためのテーパー構造4,5を有し、通行方向に対する外側面を枠部材9によって嵌合させた構造を有し、2枚以上の合板を、通行方向に対して並列させ、合板の対向側面をシート材6によって連結させ、合板が互いに重なり合うように折り畳み可能にする。更に、枠部材のうち、合板のテーパー構造に嵌合する部位の外周に、衝撃吸収材7を装着する。【選択図】図1
