At present, the construction site supports a part of the beam side template according to the size of the composite slab, which often causes the difference between the arching of the local template and the overall arching. The composite slab itself is also warped and deformed due to production reasons. At the same time, because the frame is affected by the weight of the composite slab, even if the double-sided adhesive strip is pasted on the supported template, it is still impossible to avoid a certain gap between the composite slab and the template. When pouring concrete, leakage and other phenomena occur at the junction of the two. After the template frame is disassembled, it needs to be polished, which adds unnecessary processes, affects the visual quality of the post-casting joint of the composite slab, causes delays in the construction period, and wastes costs.
