核电站环承梁吊装用吊具
本技术涉及核电站建造领域,尤其涉及一种对核电站中的环承梁进行吊装用的吊具。
技术介绍
目前,在对核电站中的环承梁进行吊装时,通常是在环承梁的组件全部运送到达施工现场时,先在地面上利用临时螺栓对环承梁进行预拼装,并在拼装完成后对预拼装形成的环承梁的下翼缘内环的圆度进行检测,若该环承梁的下翼缘内环的圆度符合设计及安装要求,则对预拼装形成的环承梁中的各段进行编号后并拆开,然后将环承梁的各段分别吊装至穹顶下方的牛腿处进行组装作业,完成环承梁的吊装。这样吊装环承梁,需对环承梁的每一段进行单独吊装,吊装次数多;在牛腿处进行组装作业,为高空组装作业,且作业量大,进而导致施工安全风险及质量风险大;吊装次数多,高空组装作业量大,导致施工周期长,场地占用时间长。
技术实现思路
为减少工作量,降低施工安全风险及质量风险,缩短施工周期,本技术提出一种核电站环承梁吊装用吊具,该核电站环承梁吊装用吊具包括分配器、吊索及吊耳组件,所述分配器包括支撑件、连接耳板和3n个吊耳板,且n为大于1的正整数;所述连接耳板固定设置在所述支撑件的顶部,且所述连接耳板上设置有连接吊孔;所述吊耳板 ...
