Short suspender longitudinal bridge direction offset adjusting device
The invention relates to a short suspender longitudinal bridge direction offset adjusting device which is characterized in that elliptical holes are correspondingly formed in an arch rib and a bridge deck, a plurality of pairs of lug plates are correspondingly arranged above the arch rib and below the bridge deck, and the upper end and the lower end of a short suspender penetrate through the elliptical holes in the arch rib and the bridge deck respectively; and the upper end and the lower end of the short suspender are respectively anchored on the drum-shaped section area between the lug plates through prestressed anchorage devices. The structure has the advantages that the upper lug plate and the lower lug plate are arranged on the arch rib and the bridge deck respectively, the upper end and the lower end of the short suspender are anchored to the ends of the upper lug plate and the lower lug plate respectively, and therefore the short suspender is longer than a traditional bridge structure, and the bending stress resistance of the short suspender is effectively improved; torsion dampers are additionally arranged on the two sides of the anchoring end of the short suspender, when the short suspender vibrates at high frequency, the torsion dampers provide buffering force for the short suspender, and the vibration effect of the short suspender is reduced.
本发明涉及一种短吊杆纵桥向偏移调节装置，拱肋和桥面板上对应地开设有椭圆孔洞，拱肋上方和桥面板下方对应地设有数对耳板，短吊杆的上下两端分别贯穿拱肋和桥面板上的椭圆孔洞，短吊杆的上下两端分别通过预应力锚具锚固在耳板间的鼓形截面区上。本发明的有益效果是：通过在拱肋和桥面板分别设置上下耳板，短吊杆的上下两端分别锚固在上下耳板的端部，因此短吊杆的长度相比传统桥梁结构中更长，有效提升了其抵抗弯曲应力的能力；在短吊杆的锚固端两侧加装扭转阻尼器，当短吊杆发生高频振动时，扭转阻尼器对其提供缓冲力，降低短吊杆的振动效应。
