A prefabricated panel demoulding device

technical field

The utility model relates to the construction field, in particular to a demoulding device for prefabricated panels.

Background technique

At present, the ultra-high-strength concrete (UHPC) precast slabs produced by domestic prefabricated component manufacturers are mainly produced by fixed table formwork. When the UHPC slab reaches the demoulding strength, it is manually demoulded by tools such as crowbars and spreaders. In addition, the currently produced UHPC boards are mainly used as external hanging boards, and the specifications are relatively small, mainly 1200mm×900mm or 900mm×600mm, and the thickness is relatively thin, generally less than 25mm.

When producing UHPC prefabricated panels according to the current production method, there are mainly the following problems, including:

First of all, the labor intensity is high and the production efficiency is low. When producing UHPC prefabricated panels, the demoulding is mainly done manually through simple tools. Therefore, the labor intensity is high and the production efficiency is relatively low.

Secondly, the quality is relatively poor. For the UHPC prefabricated panels currently produced, tools such as crowbars will inevitably damage the UHPC prefabricated panels during the demoulding process, and the UHPC prefabricated panels cannot be effectively guaranteed.

To sum up, how to provide a demoulding device for prefabricated panels with low labor intensity, high production efficiency and good quality has become an urgent technical problem to be solved by those skilled in the art.
