Description

隐形地脚螺栓
技术领域
本实用新型属于输配电及用电工程专业-变电站-变电工程土建结构设计技术领域,主要用于变电站中的高压电抗器、变压器与基础连接安装固定,也可用于其它大件设备与基础连接。
背景技术
变电站中的高压电抗器、主变压器等大型设备要求与基础有可靠连接、拆装方便及很好的抗震性能,宜采用地脚螺栓连接方式。但由于设备自重较大,就位时多采用滚杠、滑道等推拉方式安装,要求设备基础顶面平整、无凸起物,因此,高压电抗器、主变压器等大型设备与基础连接多数采用现场焊接方式,造成焊接部位防腐困难、拆装不方便、抗震性能较差。对于某些必须使用地脚螺栓固定的设备,预埋的地脚螺栓在安装过程中极易受到大件设备的碰撞而损坏,增加了设备安装难度。
实用新型内容
本实用新型所要解决的技术问题是在满足大件设备拆装方便的前提下,提供一种造价低、施工方便、抗震性能好的隐形地脚螺栓。
为解决上述技术问题,本实用新型提供一种隐形地脚螺栓,其特征在于:包括箱形铁件和活动螺栓,箱形铁件顶板上面开有螺栓孔,侧板及背板外侧设有锚筋,活动螺栓设在箱形铁件内。
为增加强度,箱形铁件内中间设有肋板。
本实用新型结构构造合理,结构性能与受力性能匹配统一,可有效地保证设备与基础连接强度,满足设备抗震和定位要求,为大型设备在基础上就位安装和搬运提供了方便条件。
附图说明
图1为本实用新型的结构示意图;
图2为本实用新型使用状态结构示意图。
具体实施方式
参考图1,本实用新型包括预埋箱形铁件和活动螺栓8,箱形铁件包括顶板2、侧板3、背板4、底板7,顶板2上面预留螺栓孔1,侧板及背板外侧设有锚筋5,活动螺栓设在箱形铁件内,6是肋板。
参考图2,本实用新型设备安装前活动螺栓8位于箱型铁件内,设备就位后,活动螺栓8与设备底板9连接。当需要移动设备时,松开活动螺栓8,将其下沉至箱形铁件内。
需要安装设备时将活动螺栓上提到基础顶面,卸掉螺丝帽时活动螺栓隐藏在箱形铁件中,上部设备可以在基础顶面直接滑动或滚动,不受活动螺栓的影响。当活动螺栓长度小于预埋的箱形铁件净高时,也可以在设备就位后安装活动螺栓。
