Background technique

In recent years, prefabricated construction projects have been gradually developed, and PC laminated board components are the most important components of prefabricated buildings, and their installation area is large, while the single laminated board itself has the characteristics of large plane size and small thickness. It is particularly important to take protective measures for the laminated boards to prevent the boards from cracking.

The traditional non-fabricated building construction placing machine is directly placed on the beam or slab surface reinforcement of the cast-in-place floor slab, and the bottom surface of the formwork at the corresponding position is reinforced. However, when the prefabricated construction project is pouring the concrete after installing the laminated slab, the laminated slab The slab surface cannot directly bear the load of the outriggers of the placing machine, so the placing machine is not used when pouring the concrete, and the concrete pump is directly used to move the concrete on the slab surface for pouring, which will lower the construction efficiency and affect the installation quality of the laminated slab.
