Vibration damping device for building

Abstract

The invention relates to a vibration reducing device for a building. The vibration reducing device comprises a top plate, a bottom plate and a vibration reducing assembly arranged between the top plate and the bottom plate; the vibration reducing assembly comprises a longitudinal vibration reducing assembly and a transverse vibration reducing assembly sleeving the longitudinal vibration reducing assembly; the transverse vibration reducing assembly comprises a vibration reducing elastomer sleeving the longitudinal vibration reducing assembly, a plurality of supporting columns I and a plurality of supporting columns II, wherein the multiple supporting columns I and the multiple supporting columns II are arranged in the vibration reducing elastomer in the longitudinal direction in a staggered mode; and the multiple supporting columns I are correspondingly arranged on the outer sides of the multiple supporting columns II and used for being matched with the supporting columns II to abut against the corresponding supporting columns I and buffer the borne transverse shear force when transverse vibration generates displacement. Energy absorbing and vibration reducing to borne longitudinal vibration force and transverse vibration force in different directions can be facilitated, meanwhile, the higher structure stability is achieved, the conventional anti-seismic requirements of the building are met, vibration noise pollution brought by vibration sources near the building can be further lowered effectively and advantageously, the structure is simple and compact, and manufacturing is easy.

Description

technical field [0001] The invention relates to the field of building energy absorption and vibration reduction, in particular to a building vibration reduction device. Background technique [0002] With the rapid development of the national economy, people have higher and higher requirements for quality of life, and higher requirements for vibration and noise reduction. With its advantages of being fast, punctual, energy-saving, convenient, and effectively alleviating ground traffic congestion, rail transit has quickly become a hot spot in the development of urban traffic construction. However, serious vibration and noise pollution are generated during the high-frequency operation of rail transit, which has a certain negative impact on the buildings along the line and people's work and life. Therefore, while the buildings along the rail transit meet the corresponding national seismic code design, Environmental pollution caused by vibration and noise must also be considered...

Problems solved by technology

However, the high-frequency operation of rail transit produces serious vibration and noise pollution, which has a certain negative impact on the buildings along the line and people's work and life. Therefore, while the buildings along the rail transit meet the corresponding national seismic code design, The environmental pollution caused by vibration and noise must also be considered, such as setting a vibration-absorbing structure between the foundation part of the building and the superstructure of the building
