Background

In the assembly type building construction, the prefabricated composite slabs are sequentially stacked according to the hoisting plan and the number, and the control of the hoisting quality is mainly in the aspect of precision control of construction measurement. When the prefabricated laminated slab is constructed in a general engineering project: the method comprises the following steps of directly hoisting the laminated slab to an operation surface from a hook on a transportation component vehicle, stopping descending when the distance from a plate surface is 500mm, stabilizing the laminated slab by an operator, guiding the laminated slab to slowly descend to an aluminum template, and picking and correcting after the component is stabilized. And checking the horizontal position of the laminated slab according to the aluminum die on the beam side, and adjusting the horizontal displacement of the laminated slab through a crowbar to enable the laminated slab to meet the requirements. There are two problems with this common practice, one being that the precision of the prefabricated laminate cannot be guaranteed. The prefabricated laminated slab is provided with the following precision requirements: the short side of the laminated slab is supported on the beam or shear wall by 10mm, and the allowable error is 5 mm. When the prefabricated superimposed sheet of hoisting equipment installation is used, because hoist and mount wire rope has the swing condition, it is big partially to prefabricated superimposed sheet hoist and mount precision influence, and the prefabricated superimposed sheet after the position that falls is difficult to reach the requirement, even the manual work uses the crowbar to carry out the off normal adjustment, partial superimposed sheet precision also can appear and is not conform to the requirement.

The second problem is to affect the work efficiency: when the prefabricated laminated slab is in a falling position, a tape measure is needed to measure and control the falling position of the prefabricated laminated slab and slowly adjust the integral falling position state of the prefabricated laminated slab, so that more time is delayed; when the prefabricated superimposed sheet appears the hoist and mount precision and is not conform to the requirement, need use crowbar adjustment prefabricated superimposed sheet position, need invest more manpowers. To better solve the problem, a tool capable of effectively controlling the precision of the prefabricated composite slab and increasing the work efficiency is urgently needed so as to ensure the construction quality and the construction efficiency of the fabricated composite slab.
