PCa WALL BALUSTRADE, WALL BALUSTRADE STRUCTURE, AND METHOD OF CONSTRUCTING WALL BALUSTRADE STRUCTURE
To provide a PCa wall balustrade, a wall balustrade structure, and a method of constructing the wall balustrade structure that can be constructed in a short period of time and has a low construction cost and manufacturing cost without the need to bolt the PCa wall balustrades to each other.SOLUTION: A precast reinforced concrete PCa wall balustrade 1 juxtaposed along an edge of a side end of a road floor slab includes: anchor holes 2 opened on a bottom surface for inserting anchor bolts (12) having an enlarged section formed at an end in the longitudinal direction; a spiral reinforcement (6) consisting of a spiral-shaped reinforcement buried around the anchor holes 2; a protrusion 3 formed on one end face in the width direction and a concave groove 4 formed on the other end face, which are fitted to the adjacent PCa wall balustrade 1 and serve as side shear keys. The adjacent PCa wall balustrades 1 are not connected via tensile members that transmit tensile force.SELECTED DRAWING: Figure 1
【課題】ＰＣａ壁高欄同士をボルト接合する必要がなく、短期間で施工可能で施工コスト及び製造コストが安いＰＣａ壁高欄、壁高欄構造、及び壁高欄構造の構築方法を提供する。【解決手段】道路床版の側端部の縁に沿って並設されるプレキャスト鉄筋コンクリート製のＰＣａ壁高欄１において、長手方向の端部に拡大部が形成されたアンカーボルト（１２）を挿置するための底面に開口するアンカー孔２と、このアンカー孔２の周りに埋設された螺旋状の鉄筋からなるスパイラル筋（６）と、隣接するＰＣａ壁高欄１と嵌合して側面せん断キーとなる幅方向の一方の端面に形成された凸条３及び他方の端面に形成された凹溝４と、を設け、隣接するＰＣａ壁高欄１と引張力を伝達する引張部材を介して連結しない。【選択図】図１
