网架支座技术领先,网架支座质量可靠,网架支座服务,客户的满意是衡水广润最的追求。
网架支座的主要技术性能:
1、可承载竖向载荷;
2、具有抗竖向拉力的性能,保证竖向地震时上下结构不脱节;
3、具有抗水平力的性能,保证水平地震时结构不脱节;
4、可适应径向、环向的位移要求;
5、可适应任意方向的转角要求;
6、减震支座具有良好的减震性能;
7、支座通过球面传力,不出现力的缩颈现象,作用在上、下结构的反力比较均匀;
8、支座不用橡胶承压,不存在橡胶老化对支座的影响,使用寿命长。
网架支座包括固定支座、单向、双向三种型式,22个等级,其水平承载力、竖直方向拔力及支座的整体强度均比普通支座有大幅度提高。该系列支座采用弹性减振元件,当水平力大到一定程度后,减振弹簧开始发生弹性变形实现缓冲作用。当结构发生转角时,球芯产生转动,释放上部结构产生的转矩。地震时,刚性抗震措施和柔性减振措施同时发生作用,以抵御巨大的地震输入能量,这样既能保证桥梁上、下结构合理相对位移,减小地震力的放大系数,又使结构保持统一性。该支座可抵御8-11度地震,对高烈度地震区尤其直下型地震区的工程结构有良好的抗震减振作用。
网架支座技术参数
1、支座竖向承载力分为300KN~10000KN十四个级别;
2、支座的抗水平力为竖向承载力的20%;
3、设计转角为0.08rad(可根据用户要求另行设计)
4、支座的径向位移量±20mm-±50mm,环向位移量±60mm-±100mm;
注:以上技术要求均可根据客户要求设计生产
