CONSTRUCTION METHOD FOR MAIN TOWER
To provide a construction method for a main tower capable of reducing work at a construction site and shortening a construction period in the main tower of an extradosed bridge or a cable-stayed bridge.SOLUTION: A main tower includes a steel shell member 12, an inner concrete part 13 provided inside the steel shell member 12, and an outer concrete part 14 provided outside the steel shell member 12. A diagonal member fixing steel shell member 12b to which a diagonal member is fixed is manufactured in a factory or the like in a state in which an outer pipe 25b through which the diagonal member is inserted is attached. When the diagonal member fixing steel shell member 12b is installed at a predetermined position, a part of the outer pipe 25b passes through the outer concrete part 14 one step lower than the diagonal member fixing steel shell member 12b. Therefore, the outer concrete part 14 of each stage is formed in parallel with or in front of or behind the inner concrete part 13 of the next higher stage after the diagonal member fixing steel shell member 12b of the stage is installed.SELECTED DRAWING: Figure 8
【課題】エクストラドーズド橋や斜張橋の主塔に関して、施工場所での作業を軽減し、工期を短縮できる主塔の構築方法を提供する。【解決手段】主塔は、鋼殻部材１２と、鋼殻部材１２の内部に設けられた内部コンクリート部１３と、鋼殻部材１２の外部に設けられた外部コンクリート部１４を含む。斜材が定着される斜材定着鋼殻部材１２ｂは、工場等にて、斜材が挿通される外筒管２５ｂを取り付けた状態に製造される。斜材定着鋼殻部材１２ｂが所定の位置に設置されると、外筒管２５ｂの一部は、その斜材定着鋼殻部材１２ｂよりも一段下の外部コンクリート部１４を通過する。このため、各段の外部コンクリート部１４は、一段上の斜材定着鋼殻部材１２ｂを設置した後に、一段上の内部コンクリート部１３と平行して又は前後して形成される。【選択図】図８
