Construction method of tension balance type anti-seismic and vibration-isolation foundation

CHEN YANG / ZHANG SILU / LI XI

The invention discloses a construction method of a tension balance type anti-seismic and vibration-isolation foundation, relates to a foundation for an earthquake area, and solves the problem that the anti-seismic and vibration-isolation effect of the existing anti-seismic and vibration-isolation foundation is poor. The foundation pit is excavated, and a foundation bearing layer is constructed in the foundation pit; secondly, a support structure is installed on the top face of the foundation bearing layer, specifically, a lower support is installed at first, the position of the lower support is adjusted, then a ball is placed in a lower spherical hinge bowl buckle, an upper support is installed, a spherical hinge structure is formed between the upper support and the lower support, at least three tensioning pieces are installed between the upper support and the lower support, and the tensioning pieces are installed on the top face of the foundation bearing layer; a damper is arranged on each tensioning piece; thirdly, an upper structure is installed on the top face of the support structure; and finally, the foundation pit is filled with anti-vibration filler to the top of the support structure. The method is used for construction of anti-seismic vibration isolation foundations of small buildings and light structures.

本发明公开了一种张拉平衡式抗震隔振基础的施工方法，涉及一种地震区用的基础，解决现有抗震隔振基础抗震隔振效果不佳的问题，采用的技术方案是：张拉平衡式抗震隔振基础的施工方法，首先，在开挖基坑与并在基坑内施工基础持力层；其次，在基础持力层的顶面安装支座结构，具体是先安装下支座并对其调整位置，再将球体放置于下球铰碗扣内，再安装上支座，上支座与下支座之间形成球铰结构，再在上支座与下支座之间安装至少三根张拉件，每根张拉件上分别设置阻尼器；再次，在支座结构的顶面安装上部结构；最后，在基坑内填筑阻振填料至支座结构的顶部。本发明用于小型建筑物和轻型结构抗震隔振基础的施工。
