Prefabricated laminated slab supporting device

The utility model relates to the field of prefabricated buildings, in particular to a prefabricated laminated slab supporting device which comprises a supporting vertical rod and a jacking vertical rod, a containing hole is formed in one end of the supporting vertical rod, the jacking vertical rod is inserted into the containing hole, scales are arranged on the jacking vertical rod, a lifting mechanism is installed on the supporting vertical rod, and the jacking vertical rod is inserted into the containing hole. The lifting mechanism can be used for lifting the jacking vertical rod, and a fixing piece used for fixing the jacking vertical rod is installed on the supporting vertical rod. The problem that the construction efficiency is low due to the fact that the height of the supporting device is repeatedly determined is solved. 本申请涉及装配式建筑的领域，尤其涉及一种预制叠合板支撑装置，其包括支撑立杆和顶托立杆，所述支撑立杆的一端开设有放置孔，所述顶托立杆插入所述放置孔内，所述顶托立杆上设置有刻度，所述支撑立杆上安装有升降机构，所述升降机构可用于对顶托立杆进行升降，所述支撑立杆上安装有用于对所述顶托立杆进行固定的固定件。本申请改善了因反复确定支撑装置高度而导致的施工效率较低的问题。
