Description

TECHNICAL FIELD

[0001] The utility model relates to the construction technology field of building laminated slab, specifically relates to a laminated slab cast-in-place band reinforcing device. BACKGROUND

[0002] Laminated slab is one of common prefabricated components, which is composed of bottom concrete prefabricated slab and upper concrete cast-in-place layer. Compared with cast-in-place floor slab, laminated slab can reduce formwork and thus shorten construction period, and the construction quality of laminated slab is more guaranteed. However, in actual construction process, the formwork at the cast-in-place band part of laminated slab often does not fit tightly with the laminated slab joint, causing grout leakage, which further increases the labor cost and material cost for later chiseling and repairing, and increases construction cost. Grout leakage at the laminated slab band affects the one-time forming quality of laminated slab construction, and also affects the visual quality of the structure.

[0003] Chinese patent with publication number CN219196707U discloses a reinforcing device for laminated slab cast-in-place band, which comprises a fixed plate, a truss reinforcement is fixed on the top of the fixed plate, a band connecting port is arranged on the top of the fixed plate, a laminated slab body is fixed on the bottom of the fixed plate, a thick formwork is connected to the bottom of the laminated slab body, and a square steel is installed on the bottom of the thick formwork. The device is provided with a reinforcing mechanism, which drives the metal plate and the reinforcing plate to move together. One side of the reinforcing plate can be attached to the outside of the corresponding thick formwork, achieving the purpose of reinforcing the laminated slab cast-in-place band and improving the stability of the laminated slab cast-in-place band. The device is provided with a stabilizing device. The connecting rod on one side of the movable pad can extend to the outside of the stabilizing shell, and one end of the connecting rod is inserted into the preset positioning hole of the thick formwork, thereby achieving the purpose of improving the stability between the laminated slab body and the thick formwork and achieving the effect of further reinforcement.

[0004] However, the reinforcing device for laminated slab cast-in-place band has a relatively complex structure, which makes the disassembly and assembly process relatively complicated and time-consuming and labor-intensive, and the pull-reinforcing method makes the reinforcement at the joint between the laminated slab and the cast-in-place band not in place. In addition, the aluminum formwork support system requires a double-stand rod system. If grout leakage or misalignment occurs at the laminated slab, not only does it need to be polished and repaired again, but also the joint between the laminated slab band is not straight, which directly affects the engineering quality and increases the labor cost and causes material waste.
