预制混凝土墙板专用快拆型盲孔工装件

Abstract

本实用新型给出了一种预制混凝土墙板专用快拆型盲孔工装件,涉及预制混凝土墙板生产技术领域，该工装件包括工装件主体、定位件及定位组件。工装件主体由锥台状橡胶外套包裹内设固定螺纹孔的柱形钢管构成，其侧壁开设两个装配孔。定位件为橡胶材质，上端设柱形凸块与装配孔过盈插接，下端设浆液隔离凸起；定位组件包含焊接于模台面的定位螺母及固定于定位件底部的定位螺栓，实现定位件预固定。安装时，定位件通过螺栓‑螺母组件垂直固接于模台，工装件主体按压插接至定位件凸块上，再经固定螺栓锁紧边模。本实用新型解决了传统螺纹连接工装易偏移、拆装繁琐的问题，通过模台预固定与弹性插接结构，实现快速拆装，提高盲孔成型质量及施工效率。
