Description

A positioning device for installing prefabricated building panels

Technical field

The utility model relates to the technical field of building prefabricated panels, specifically a positioning device for installing prefabricated building panels.

Background technique

Most of the prefabricated building panels are cement prefabricated panels, which are walls prefabricated with Portland cement and steel keels. They are usually prefabricated into plate shapes by formwork, hence the name prefabricated building panels. They are mostly used in buildings with brick-concrete structures. In the early days, it was prefabricated and used directly in building construction. It was widely used to save the time of building red bricks. Most of the prefabricated building panels were installed by cranes, which is very common on construction sites.

Precast building panels are usually installed by a crane. In some areas with complex roads, it may be inconvenient for a crane to enter the construction area. Moreover, the panels will inevitably shake when installing precast building panels, making it impossible to install the precast building panels in a timely manner. Where needed, and the excessive weight of some prefabricated building panels will cause the clamping robotic arm to fall rapidly and damage the device. During the process of transporting the prefabricated building panels, the continuous movement of the pulleys will also cause the prefabricated building panels to be difficult to place. Reaching the designated location in a short time will affect the installation process, so the entire device needs to be stopped in time when it reaches the designated location.
