Description

TECHNICAL FIELD

[0001] The utility model relates to the field of laminated slab construction technology, and particularly relates to a laminated slab belt reinforcing component capable of avoiding slurry leakage. BACKGROUND

[0002] In building assembly construction, laminated slabs are widely used in residential buildings, public buildings, and industrial and warehouse buildings, and are formed by combining a prefabricated laminated slab bottom plate with a cast-in-place concrete layer. The traditional construction method is to use a formwork under a scaffold for support and reinforcement. In the actual installation process, it is inevitable that a gap will be generated at the overlapping joint between the laminated slab and the cast-in-place slab belt. If no measures are taken during the concrete pouring process, slurry leakage will occur at the overlapping gap between the laminated slab and the cast-in-place slab belt under the action of construction load and concrete vibration. In addition, under the extrusion action of the slurry, the formwork is prone to deformation, and after the formwork is removed, there will be slurry floating at the joint between the formwork and the prefabricated laminated slab, which affects the visual quality.
