Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a fixing device for a laminated slab strip formwork. BACKGROUND

[0002] In the construction of fabricated structures, the installation of laminated slabs generally uses a special independent support system. This support system cannot reinforce and support the strip formwork at the cast-in-place slab strip, which leads to poor surface quality of the concrete slab strip and easy occurrence of exposed reinforcement.

[0003] For example, a reinforcing device for a laminated slab cast-in-place slab strip disclosed in Patent No. CN219196707U includes a fixed plate, a truss reinforcement fixed to the top of the fixed plate, a slab strip connecting port provided at the top of the fixed plate, a laminated slab body fixed to the bottom of the fixed plate, a thick formwork connected to the bottom of the laminated slab body, and a square steel installed at the bottom of the thick formwork. The reinforcing device is provided with a reinforcing mechanism, which pushes the metal plate and the reinforcing plate of the movable frame to make one side of the reinforcing plate adhere to the outside of the corresponding thick formwork, thereby achieving the purpose of reinforcing the laminated slab cast-in-place slab strip and improving the stability of the laminated slab cast-in-place slab strip. The reinforcing device is also provided with a stabilizing device, and the connecting rod on one side of the movable pad can extend to the outside of the stabilizing shell and insert one end of the connecting rod into the pre-designed 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 device tightens the two sides of the thick formwork through the reinforcing mechanism and the stabilizing device, so that the rear formwork and the laminated slab are stably adhered. Since the laminated slab itself has a certain length, only the two sides of the formwork and the laminated slab are fixed, and due to the influence of the weight of the upper layer of concrete, the middle part of the laminated slab may be curved downward, which may affect the flatness of the assembled formwork and laminated slab, and there is limitation.
