I-shaped steel beam vibration reduction device and I-shaped steel composite beam
The invention relates to the technical field of bridge vibration reduction, and particularly discloses an I-shaped steel beam vibration reduction device and an I-shaped steel composite beam. The I-shaped steel composite beam comprises a beam body and beam vibration reduction devices, wherein the beam body comprises an upper flange plate, a lower flange plate and web plates; one beam vibration reduction device or two symmetrical beam vibration reduction devices are arranged on each web plate; and each beam vibration reduction device comprises a dowel bar, a bevel amplifying rod and a damper, the dowel bar is rotatably connected with the upper flange plate of the I-shaped steel beam, the bevel amplifying rod comprises a connecting end and an amplifying end, the connecting end is rotatably connected with the dowel bar, the bevel of the bevel amplifying rod is rotatably arranged on the lower flange plate, the distance between the bevel and the connecting end is smaller than that between the bevel and the amplifying end, and the damper is rotatably arranged on the web plate of the I-shaped steel beam and is further rotatably connected with the amplifying end. The problems of the increase of the construction cost and the influence on the net width of the bottom of a bridge and navigation because a special damper support member is needed for arranging a vertical damper between two piers of the bridge in the prior art can be solved.
本发明涉及桥梁减振技术领域，具体公开了一种工型钢梁减振装置及工型钢组合梁，该工型钢组合梁包括：梁体，其包括：上翼缘板、下翼缘板和腹板；还包括每个腹板处设置的一个梁减振装置或者两个对称设置的减振装置，每个减振装置包括：传力杆，其与工型钢梁的上翼缘板转动连接；还包括折角放大杆，其包括连接端和放大端，连接端与传力杆转动连接，其折角处转动设置在下翼缘板上，并且设在折角处到连接端的距离小于到放大端的距离；还包括阻尼器，其可相对转动地设在工型钢梁的腹板上，还与放大端转动连接。能够解决现有技术中在桥梁两桥墩之间布置竖向阻尼器需专门的阻尼器支撑构件，将增加工程造价和影响桥梁底部净宽影响通航的问题。
