SUSPENSION BRIDGE FRAME, SUSPENSION BRIDGE, AND SUSPENSION BRIDGE ERECTION METHOD
To provide a suspension bridge frame, in which upper left and right parts and lower left and right parts are held by cables, and a suspension bridge using the suspension bridge frame with high stability; and to provide a suspension bridge erection method, a suspension bridge, and a suspension bridge frame used by these, constructed, at a low cost, by sequentially connecting suspension bridge frames on the shore side and sending them to the opposite shore side, and which excels in safety during erection.SOLUTION: In a suspension bridge frame 30 and a suspension bridge 80, main cables 50a, 50b are respectively fixed and held at the upper left, upper right, lower left, and lower right of the suspension bridge frame 30 such that the stability can be improved. In the suspension bridge erection method, temporary suspension of the suspension bridge frame 30 to the main cables 50a, 50b and connection by a connection member are performed on the shore side on the ground, and this is sent to the opposite shore side for erection. As a result, work at a high place is reduced and safety is improved, work efficiency is improved, and the cost can be reduced by shortening the construction period and reducing labor costs.SELECTED DRAWING: Figure 7
【課題】左右上部、左右下部をケーブルで保持する吊橋フレーム、及びこの吊橋フレームを用いた安定性の高い吊橋を提供する。また、吊橋フレームを岸側で順次連結し対岸側に送り出して架設を行う低コストで且つ架設時の安全性に優れた吊橋の架設方法、吊橋、及びこれに用いる吊橋フレームを提供する。【解決手段】この吊橋フレーム３０及び吊橋８０は、吊橋フレーム３０の左上、右上、左下、右下のそれぞれに主ケーブル５０ａ、５０ｂが固定しこれを保持するため、安定性の向上を図ることができる。また、この吊橋の架設方法は、吊橋フレーム３０の主ケーブル５０ａ、５０ｂへの仮止め及び連結部材による連結を岸側の地上で行い、これを対岸側に送り出して架設を行う。これにより、高所作業が減少し安全性が向上する他、作業効率が上がり、工期の短縮と人件費の低減によるコスト削減を図ることができる。【選択図】図７
