DISPLACED CONTROL SYSTEM FOR BRIDGE UPPER PART STRUCTURE DRAW AND CONTROL METHOD

摘要

PURPOSE: A displacement control device and a displacement control method for drawing the upper structure of a bridge are provided to control the unstable displacement of an upper structure occurred when the upper structure is drawn. CONSTITUTION: A displacement control device for drawing the upper structure of a bridge comprises a lower body(100), an intermediate body(200), an upper body(300), and a bearing plate. The lower body is composed of a rectangular steel plate(110) and multiple support plates(120). The support plates are vertically installed on the rectangular steel plate. The intermediate body is rotatably coupled to the support plates through bolts(B) and nuts(N) and is composed of multiple steel plates(210). The upper body is coupled to the steel plates of the intermediate body and is composed of a rectangular steel plate(310), multiple fixed plates(320), and triangular plates(330). The fixed plates are vertically installed on the rectangular steel plate. The triangular plates are horizontally installed between the rectangular steel plate and the fixed plates. The bearing plate is fixed between the support plates of the lower body and the steel plates of the intermediate body.
