Description

(54) УСТРОЙСТВО ДЛЯ ГАШЕНИЯ КОЛЕБАНИЙ(54) DEVICE FOR EXTINGUISHING VIBRATIONS

РАЗРЕЗНЬК ПРОЛЕТНЫХ СТРОЕНИЙ МОСТАUNIVERSAL OF THE BRIDGE BRIDGE

. I , ; I Изобретение относитс  к мостосттроению и может быть использовано/ дл  гашени  колебаний разрезных пролетш 1х строений мостов. . I; I The invention relates to bridge construction and can be used / for damping oscillations of split 1-span bridge structures.

Известно устройство дл  гашени  колебаний разрезных пролетных строений моста, включающее подпруйиненную зат жку с анкерами, укрепленную в верхней части смежных пролетный строений, и накладки, жестко укрепленные в нижней части смежных пролетных строений tlA device is known for damping oscillations of split span structures of a bridge, including a podruzhennoy tightening with anchors, fortified in the upper part of the adjacent span structures, and lining, rigidly fortified in the lower part of adjacent span structures tl

Недостаток этого устройства заключаетс  в относительно невысокой надежности его работы ввиду возможной многократной в процессе колебаний пластификащш или потери усто чивости укрепленными обоими концами в нижней части смежных пролетных строений накладками что приводит к пониженной выносливости и хру111КС)сти устройства. Кроме того, наличие этих накладок приближает статическую схему пролетного строени  к нераэрёзной , что также снижает эффектив.ность устройства.The disadvantage of this device lies in the relatively low reliability of its operation due to the possible repeated plasticization or loss of stability during the oscillations by the reinforced at both ends in the lower part of the adjacent spans, which leads to reduced endurance and sharpness of the device. In addition, the presence of these pads brings the static scheme of the span to the non-radial one, which also reduces the efficiency of the device.

Наиболее близким к предлагаемому по технической сущности и достигаемому эффекту  вл етс  устройство дл  гашени  колебаний разрезных пролетHbix строений моста, включающее демпфирующее приспособление, размещенное между обраще1 ными друг к другу попками парных вертикалышх уголков, The closest to the proposed technical essence and the achieved effect is a device for damping the oscillations of the split span of Hbix bridge structures, including a damping device, placed between the butt pairs of vertical vertical corners facing each other,

10 жестко укрепленных другими полками симметрично на стенках главных балок смежных пролетных строений, причем обращенные друг к другу полки уголков выполнешз с соосными отверсти ми 10 rigidly reinforced by other shelves symmetrically on the walls of the main beams of adjacent spans, with the overhanging corners facing each other with coaxial holes

IS под бол1Ъ1, а демпфирукицее приспособление выполнено в виде набора шайб из упруго сжимаемого материала 2.IS under bol1'1, and the damping device is made in the form of a set of washers of elastically compressible material 2.
