Technical Field

[0001] The utility model relates to the technical field of composite buildings, in particular to a composite building roof height limiting structure. Background Art

[0002] Composite slabs are assembled integral slabs made of prefabricated slabs and cast-in-place reinforced concrete layers. Composite slabs have good integrity, and the upper and lower surfaces of the slabs are flat, which is convenient for finishing layer decoration. They are suitable for high-rise buildings and large-span buildings that require high overall rigidity. Modern composite slabs generally include cast-in-place layers and composite layers. Usually, the composite layers are prefabricated in the factory, while the cast-in-place layers are constructed and poured with cement on the construction site. This connection method can better connect horizontal and vertical components.

[0003] At present, the construction height of the composite roof slab is generally between 2.7m and 3.5m. At this time, in order to meet the installation requirements of the composite roof slab, it is necessary to limit the height of the cast-in-place layer. The cast-in-place layer is shaped by the combined formwork during pouring. Therefore, the height of the combined formwork needs to be limited during construction. The structure for limiting the combined formwork in the prior art does not have good height adjustment performance and has low precision. Therefore, it is urgent to design a composite roof height limiting structure to solve the above problem. Utility Model Content
