The utility model belongs to the field of construction engineering, in particular to the isolation beam system. Including a cross beam, the two ends of the cross beam are anchored isolation bearings. The isolation bearings include an upper seal plate and a lower seal plate. A plurality of support sleeves are arranged vertically between the upper seal plate and the lower seal plate, and an annular cavity is formed between the adjacent support sleeves. A plurality of springs are arranged in the annular cavity along the radial direction of the support sleeve, and the two ends of the springs are fixed on the wall of the adjacent support sleeve. In this technical scheme, the vertical loads generated by seismic action can cause lateral displacement of multi-layer PTFE plates. The springs arranged radially along the support sleeve in the cavity can buffer the lateral displacement and reduce the negative impact of lateral displacement. At the same time, the outer edges of the upper seal plate and the lower seal plate are fixed with a number of springs, which can keep the upper seal plate and the lower seal plate moving. The relative fixed position of the state further ensures that the lateral displacement remains within a reasonable range.

隔震梁系统
本技术属于建筑工程领域,具体涉及隔震梁系统。
技术介绍
目前,在构建居民住房时,横梁都是采用现场用钢筋和混凝土浇筑的方式制作,并不具备隔震的功效。现有公知使用的横梁隔震手段主要包括加设叠层橡胶隔震支座,由钢板、橡胶硫化后在高温下分层压制而成。置于建筑物下部或桥梁墩台上,当地震发生时,阻止并减少地震能量向上部建筑或桥梁主体传播。但是,一般叠层橡胶隔震支座的橡胶在上部竖向地震荷载作用下容易使橡胶材料产生过大的侧向位移,进而会产生较大的竖向变形,容易使支座毁坏。
