Vertical buffering anti-vibration coupling beam device
The invention discloses a vertical buffering anti-vibration coupling beam device. The device comprises a steel box girder, a bridge tower lower cross beam and a connecting beam device. The two ends ofthe steel box girder are supported on the bridge tower lower cross beam and are connected with the lower cross beam of the bridge tower through the connecting beam device. The steel box girder is provided with a plurality of spaced spacing cavities in the transverse bridge direction; a sleeve hole is formed in an upper wing plate of a lower cross beam of the bridge tower; the sleeve holes are symmetrically formed close to two sides of a web of the bridge tower lower cross beam; a connecting beam hole is formed in the lower surface of the steel box girder; horn sleeves in the connecting beam device are symmetrically arranged in the sleeve holes and the connecting beam hole; horn mouths directly face each other; two ends of a steel wire rope bundle respectively penetrate through the horn mouths, the bottom end is anchored with the reducing end of each he horn sleeve at the lower part, the top end is anchored to a fixing flange arranged at the reducing end of the horn sleeve on the upperportion, and the reducing end of the horn sleeve in the sleeve hole is anchored to the upper wing plate. The fixing flange applies an acting force to the bottom face of each spacing cavity through abuffer spring arranged outside the steel wire rope bundle in a sleeving mode, so that when the steel box girder vibrates up and down, vibration is buffered to limit the amplitude.
本发明公布了一种竖向缓冲抗振连梁装置，包括钢箱梁、桥塔下横梁和连梁装置，钢箱梁的两端支撑在桥塔下横梁上，并通过连梁装置与桥塔下横梁衔接，钢箱梁在横桥向设有多个隔开的间隔腔，桥塔下横梁上翼板上开设有套管孔，该套管孔靠近桥塔下横梁腹板两侧对称布置，钢箱梁的下表面设有连梁孔，连梁装置中的喇叭套管对称布置在套管孔和连梁孔内，喇叭口相互正对，钢丝绳束两端分别从喇叭口穿过，底端与下部的喇叭套管的缩径端锚固，顶端与上部的喇叭套管缩径端的固定法兰锚固，套管孔内喇叭套管的缩径端与上翼板锚固，该固定法兰通过套在钢丝绳束外的缓冲弹簧对间隔腔底面施加作用力，使钢箱梁在上下振动时，缓冲振动限制振幅。
