Size-variable concrete preformed hole device and hole forming method
The invention relates to the technical field of concrete preformed holes, in particular to a size-variable concrete preformed hole device and a hole forming method. The bracket is fixed on a basic surface and is used for supporting the center rod; the first nut and the second nut are in threaded connection with the center rod, and the screwing directions of threads are opposite; the first positioning disc and the second positioning disc are installed on the center rod and located between the first nut and the second nut. The first scale rod and the second scale rod are hinged to the first nut and the second nut respectively and lapped on the first positioning disc and the second positioning disc respectively, and the first scale rod and the second scale rod are connected through a spring. The fixing device is fixedly connected to the first positioning disc and the second positioning disc, and the rolling skin is wound on the fixing device; and the controller is fixedly connected to the first scale rod, the second scale rod or the spring. The manufacturing cost is low, taking out is easy, no impurities are left in the hole, and the hole diameter size can be guaranteed; and the manufacturing requirements of concrete preformed holes of different shapes and sizes can be met.
本发明涉及混凝土预留孔技术领域，具体为一种可变尺寸的混凝土预留孔器及成孔方法。支架固定在基础面上，用于支撑中心杆；所述第一螺母、第二螺母与中心杆螺纹连接，且螺纹旋向相反；所述第一定位盘、第二定位盘安装在中心杆上，位于第一螺母、第二螺母之间；所述第一刻度杆、第二刻度杆分别铰接在第一螺母、第二螺母上，分别搭在第一定位盘、第二定位盘上，第一刻度杆、第二刻度杆之间通过弹簧相连；固定器固接在第一定位盘、第二定位盘上，卷皮缠绕在固定器上；所述控制器固接在第一刻度杆、第二刻度杆或弹簧上。既造价低、易取出、孔内无遗留杂物，又能保证孔径尺寸；能够满足不同形状与尺寸的混凝土预留孔的制作需求。
