Description
II
Изобретение относитс к области мостостроени и может быть использовано при возведении многопропетиых мостов с разрезными прюлетнымн строени ми.The invention relates to the field of bridge construction and can be used in the construction of multi-bridge bridges with split plyulet structures.
Известен мост, вкдючанищгй опоры, устои, керазрезное пролетное строение, установленное на опоры и устои через подвижные опорные части, демпфирующие устройства, размещенные между торцами П{юлетного строени и усто ми, каждое из которых выполнено в виде гидрюцилиндра с поршнем и соединенным с ним штоком, свободный кЪнец которого укреплен на передней грани соответствующего усто 1 .A bridge is known, including supports, abutments, a kerazreznoe span structure, mounted on supports and abutments through movable supporting parts, damping devices located between the ends of the P {yletnaya structure and the abutments, each of which is made in the form of a hydraulic cylinder with a piston and connected to it with a rod , the free end of which is reinforced on the front face of the corresponding usto 1.
Недостаток этой конструкции моста заключаетс в том, что при использовании разрезного пролетного строени размещенные на усто х демпфирующие устройства не обеспечивают передачу горизонтальной силы от временной нагрузки и температурных колебаний с пролетных строений на устои, в результате чего возрастает материалоемкость промежуточных опор, воспринимающих в данном случае горизонтальную нагрузку через неподвижные опорные части.The disadvantage of this bridge design is that when using a split span, the damping devices placed on the foundations do not ensure the transfer of the horizontal force from the temporary load and temperature fluctuations from the span structures to the foundations, as a result of which the material consumption of the intermediate supports increases, which in this case perceives horizontal load through fixed bearing parts.
Известен также мост, включающий опоры, разрезные пролетные строени , установленные на опоры через подвижные опорные части, демпфирующие прокладки из упругосжимаемого пластичного материала, размещенные в зазорах между торцами смежных пролетных строений, причем демпфирующие прокладки расположены в уровне плиты проезжей части моста 2.A bridge is also known, which includes supports, split span structures, mounted on supports through movable support parts, damping pads of resilient plastic material placed in the gaps between the ends of adjacent span structures, the damping pads located at the level of the roadway plate of bridge 2.
Недостаток известного моста заключаетс в низкой демпфирующей способности прокладок и надежности их работы, особенно в мостах, расположенных на кривой, обусловленных наличием поперечных деформаций прокладок при их обжатии, возможной неравномерностью их обжати по щирине моста, в особенности на криволинейных участках, а также возможными их смещени ми от проектного положени и остаточными деформаци ми.The disadvantage of the known bridge lies in the low damping capacity of the gaskets and the reliability of their operation, especially in bridges located on the curve, due to the presence of transverse deformations of the gaskets during their compression, possible irregularity of their compression along the width of the bridge, as well as their possible displacement from the design position and residual deformations.
Цель изобретени - повыщение демпфирующей способности прокладок и надежности их работы .The purpose of the invention is to increase the damping ability of gaskets and the reliability of their work.
