Background
The vertical stacking phenomenon of a plurality of prefabricated slabs often exists in a prefabricating factory and a transportation process from the end of maintenance to the installation of a construction site of the truss reinforced concrete prefabricated slabs. During the stacking process, the skid is usually used as a support between the prefabricated panels of each layer. At present, the arrangement position of the precast slab skids is usually determined by manual visual inspection, so that the plurality of layers of skids stacked vertically among the precast slabs are difficult to be in the same vertical line. The offset of the upper and lower skid makes the vertical gravity of the upper precast slab exert eccentric concentrated force on the lower precast slab, so that the lower precast slab is subjected to bending and shearing. With the increase of the stacking time of the prefabricated slabs, the prefabricated slabs often generate structural through seams under the action of continuous bending shear. The vibration of the truss reinforced concrete precast slab in the transportation process further aggravates the development of structural through joints caused by the offset of the skid.
In order to solve the problems, the scheme is developed accordingly.
