INSTALLING STRUCTURE OF STEEL LAND COVERING PART
PROBLEM TO BE SOLVED: To provide an installing structure of a steel land covering part capable of further smoothly deforming a rib plate, without checking deformation of the rib plate, when a concrete wall handrail receives a collision load from a vehicle.SOLUTION: In an installing structure for installing a steel land covering part 20 of a concrete wall handrail 12 in a wall body part 13 and a concrete floor slab via bolt members 37 and 38, the bolt member 37 is fastened to a peripheral edge part of a bolt fastening hole 22a by using a nut member by interposing a level-raising washer between a peripheral edge part of the bolt fastening hole 22a and itself by at least a part of bolt fastening holes 21a and 22a. The free length of the fair length is held by a part between the nut member and an inside surface of a side surface joining plate 22 in a male screw rod of the fastened bolt member 37.SELECTED DRAWING: Figure 3
【課題】コンクリート壁高欄が車両からの衝突荷重を受けた際に、リブプレートの変形が阻害されないようにして、リブプレートをよりスムーズに変形させることのできる鋼製地覆部の取付け構造を提供する。【解決手段】コクリート壁高欄１２の鋼製地覆部２０を、ボルト部材３７，３８を介して壁本体部１３及びコンクリート床版に取り付けるための取付け構造であって、ボルト締着孔２１ａ，２２ａの少なくとも一部で、ボルト部材３７が、ボルト締着孔２２ａの周縁部分との間に嵩上げ座金を介在させて、ナット部材を用いてボルト締着孔２２ａの周縁部分に締着されている。締着されたボルト部材３７の雄ネジロッドには、ナット部材と、側面接合板２２の内側面との間の部分に、相当の長さの自由長が保持されるようになっている。【選択図】図３
