Vibration reduction and isolation structure of frame-type power foundation
The invention provides a vibration reduction and isolation structure of a frame-type power foundation. The structure comprises a foundation layer and a floor slab which are oppositely arranged at intervals; a plurality of frame columns which are arranged at intervals are connected between the foundation layer and the floor slab; each frame column comprises a body and an elastic concrete layer connected with the upper end of the body; the lower end of the body is connected with the foundation layer; and the upper end of the elastic concrete layer is connected with the floor slab. According to the vibration reduction and isolation structure of the frame-type power foundation, the elastic concrete layer is arranged on the upper portion of a frame beam, the elasticity of elastic concrete is used for achieving the vibration reduction performance, and the size of structural elements can be reduced while the power requirement is met, so that the engineering cost is reduced; and compared witha frame structure provided with a damper, the vibration reduction and isolation structure has the advantages that the construction is simple, the construction period is short, and the maintenance is not needed in the later period, so that the construction cost is greatly reduced.
本发明提供了一种框架式动力基础的减隔振结构，其包括相对且间隔设置的基础层和楼板，基础层与楼板之间设有多个间隔设置的框架柱相接，框架柱包括本体和连接于本体的上端的弹性混凝土层，本体的下端与基础层相接，弹性混凝土层的上端与楼板相接。本发明的框架式动力基础的减隔振结构，通过在框架梁的上部设置弹性混凝土层，利用弹性混凝土的弹性起到减震性能，在满足动力要求的同时可减少结构构件尺寸，从而减少工程造价，并且，与安装阻尼器的框架结构相比，具有施工简单，工期短，后期免维护检修的优点，大幅度减少了工程造价。
