Description

Technical Field

[0001] The utility model relates to the technical field of slings, in particular to a composite plate lifting and transportation tool. Background Art

[0002] A composite slab is a concrete slab composed of precast and cast-in-place sections. The precast section is factory-fabricated, reinforced, and thickened to serve as a base support layer. The cast-in-place section is poured on-site over the precast section. Common dimensions for composite slabs are 2.44 meters in length and 1.22 meters in width.

[0003] The currently used composite slab hoist uses a hook to directly hook onto the steel bars of the composite slab, and can only lift one composite slab at a time, which is inefficient. In large-scale construction projects, it will greatly affect the construction progress and increase the construction period cost. It also takes a long time to load and unload. It is easy to damage the steel bars, destroy the strength and effective cross-sectional area of ​​the steel bars and the bonding force with the concrete, and bring safety hazards to the bearing capacity of the composite slab. It is inconvenient to operate, and the frequent hooking and unhooking operations increase the labor intensity and risk of operational errors of the operators, especially in high-altitude working environments. It has limited applicability, and the hook size of the hoist is large, which can only fit the composite slabs with a certain degree of exposed steel bars, which limits its versatility and increases construction costs and management difficulty. Therefore, in response to the above phenomena, a composite slab lifting and transportation tool is proposed to meet the needs of actual use. Utility Model Content
