ASSEMBLY STRUCTURE FOR PLACING ROADBED CONCRETE, CONCRETE PRESS-IN MACHINE AND ROADBED CONCRETE PLACING METHOD
To provide an assembly structure for placing roadbed concrete which resolves the problem of quality deterioration, defects, construction loss, etc., due to the finishing of a slope when placing roadbed concrete to construct it as an RC structure with the slope such as a roadbed surface of a highway ramp or a channel surface of a sub-bank of a dam.SOLUTION: A roadbed reinforcing bar is configured by upper and lower bars whose direction of either a vertical or horizontal steel bar roughly matches a direction of a drainage slope on an upper surface of a roadbed, and a substantially gate-type or rod-type stirrup reinforcement that restrains both upper and lower bars, and a net body structure is configured by a plurality of elongated belt-like net bodies having one or more planes; an axial direction of the net body is made approximately orthogonal to a direction of the drainage slope in a narrow space between the upper and lower bars; at least one plane of the net body is placed facing an approximately vertical portion of the stirrup reinforcement or a lower surface of the upper bar; and at least one end of the plane of the net body in a cross-sectional view is arranged in a slope portion in a direction of the drainage slope in a vertical cross-sectional view facing the lower surface of the upper bar.SELECTED DRAWING: Figure 3
【課題】高速道路ランプの路盤面やダムの副堤の水路面などの勾配を有するＲＣ構造物として路盤コンクリートを打設して構築する時に、勾配の仕上げに伴い品質の悪化や不良、施工のロス等が発生等を解決する路盤コンクリート打設のための組立構造物を提供する。【解決手段】路盤鉄筋を、縦横いずれかの棒鋼の方向が路盤上面の水勾配の方向に概合致する上筋及び下筋と、両者を拘束する概門型あるいは棒型のスターラップ筋とから構成すると共に、網体構造物を、帯状で細長の１以上の平面を有する複数の網体で構成し、上筋と下筋の狭隘に、前記網体の軸方向を水勾配の方向と概直交させ、少なくとも網体が有する平面の１つを、スターラップ筋を成す概鉛直の部分に面してあるいは上筋の下面に面して配置し、断面視で少なくとも網体が有する平面１つの端部は、上筋の下面に面して水勾配の方向の縦断面視で勾配部分に配置する。【選択図】図３
