Description

Technical Field

[0001] This utility model relates to the field of engineering construction, and in particular to a composite slab connection structure with a lifting formwork. Background Technology

[0002] The proportion of prefabricated buildings in housing construction projects has been increasing year by year, and composite slabs have been widely used in floor slab installation. Composite slabs are generally installed by first installing the support frame, then installing the composite slabs, and finally pouring the concrete for the post-pouring strip (also known as the connecting strip).

[0003] Currently, there are two main construction methods for connecting strip scaffolding. Method one uses full-span scaffolding, which involves a large amount of installation and dismantling of the scaffolding system for the connecting strip between adjacent composite slabs, increasing the workload of hoisting operations, construction period, and cost. Method two uses full-span scaffolding for the portion below the composite slab, while a scaffold-free system is used for the connecting strip between adjacent composite slabs. This scaffold-free system requires pre-embedded bolt sleeves within the composite slab. Before pouring the connecting strip, construction workers climb ladders to the area below the connecting strip and, standing on the ladders, use bolts to connect the rigid supports, bottom formwork, and composite slab. After the slab is fixed and the concrete is poured, the rigid supports and bottom formwork are removed one by one. This method involves pre-embedding sleeves in the precast part of the composite slab, which saves the time of erecting and dismantling the supports at the connecting strip. However, before and after the composite slab is poured, the construction workers need to raise their hands under the composite slab to install and remove the rigid supports and bottom formwork. This deviates from the principles of ergonomics, requires more connection nodes, and the construction workers' arms are prone to fatigue during installation, resulting in low efficiency. Moreover, escalator work is above 2 meters and is considered high-altitude work, which poses a high safety risk. At the same time, the pre-embedded sleeves have high requirements for pre-embedding quality, which will also increase the cost of the composite slab. Utility Model Content
