SYNTHETIC PANEL STRUCTURE

To provide a synthetic panel structure capable of easily and firmly bonding a concrete floor slab and a transverse rib.SOLUTION: A synthetic panel structure comprises a main girder panel 12, an intermediate panel 14, and a concrete floor slab 16. The main girder panel 12 has a first transverse rib 15A arranged on the upper surface of a first bottom steel plate 11 at a distance in the bridge axis direction X and integrally coupled to the concrete floor slab 16. The intermediate panel 14 further includes a second transverse rib 15B arranged at a distance from the upper surface of a second bottom steel plate 13 in the bridge axis direction X, disposed in a plurality so as to be shifted in the bridge axis direction X with respect to the first transverse rib 15A and integrally coupled to the concrete floor slab 16. The second transverse rib 15B protrudes from the end part in the bridge axis perpendicular direction Y of the second bottom steel plate 13 toward the upper surface of the first bottom steel plate 11. Each of the first transverse rib 15A and the second transverse rib 15B is formed with a plurality of open holes 18 penetrating in the bridge axis direction X at intervals in the bridge axis perpendicular direction Y.SELECTED DRAWING: Figure 1 【課題】コンクリート床版と横リブとを容易かつ強固に結合することができる合成パネル構造を提供する。【解決手段】主桁パネル１２と、中間パネル１４と、コンクリート床版１６と、を備え、主桁パネル１２は、第１底鋼板１１の上面に、橋軸方向Ｘに間隔をあけて複数配置されてコンクリート床版１６と一体に結合された第１横リブ１５Ａを有し、中間パネル１４は、第２底鋼板１３の上面に、橋軸方向Ｘに間隔をあけて、かつ、第１横リブ１５Ａに対して橋軸方向Ｘにずらされるように複数配置されてコンクリート床版１６と一体に結合された第２横リブ１５Ｂを更に有し、第２横リブ１５Ｂは、第２底鋼板１３の橋軸直角方向Ｙの端部から、第１底鋼板１１の上面に向けて突出し、第１横リブ１５Ａおよび第２横リブ１５Ｂにはそれぞれ、橋軸方向Ｘに貫かれた貫通孔１８が橋軸直角方向Ｙに間隔をあけて複数形成されている。【選択図】図１
