Description

Technical Field

[0001] The utility model relates to the technical field of reinforced concrete columns, in particular to a modular reinforced concrete structure. Background Art

[0002] Modular construction technology is considered to be the prefabricated construction technology with the highest level of prefabrication. Compared with traditional methods, it abandons the practice of relying solely on one-dimensional components (such as beams and columns) or two-dimensional components (such as walls and panels), and instead uses pre-decorated three-dimensional box modules as core prefabricated units. After these modules are produced and decorated in the factory, they are assembled on-site to form a modular building combination with diverse usage functions. Through modular construction technology, we can completely move the module production and interior decoration links to the factory environment, greatly reducing the workload of on-site construction. This approach not only improves the quality of the building, but also significantly shortens the on-site construction period, effectively saves labor and natural resources, and reduces the negative impact on the surrounding environment. Therefore, modular construction technology is regarded as a green, low-carbon, and energy-saving construction method, which is highly consistent with the current construction industry's inherent need for sustainable development.

[0003] Traditional modular reinforced concrete (MiC) buildings integrate non-load-bearing components such as formwork, lightweight partition walls, and base plates with composite slabs (precast layers) and manufacture them into boxes in the factory. The concrete three-dimensional box formwork is produced in the factory and installed on-site, and mechanical properties equivalent to cast-in-place are achieved by casting shear walls and coupling beams on-site. The main load-bearing and lateral-resisting shear walls, coupling beams and other components are all cast on-site. The top plate of the MiC module unit is equivalent to the "precast base plate" of the concrete composite floor slab and can be used as a formwork for the later-cast concrete composite layer. After the module is installed, the thin shell plate is only used as a casting formwork for the shear walls and top beams and does not participate in the structural load. The main load-bearing and lateral-resisting shear walls, coupling beams and other components are all cast on-site, such as Figure 1 As shown: beam formwork 5, lightweight exterior wall 6, composite roof slab 7, lightweight partition wall 8, wall formwork 9, base slab 10, cast-in-place structural beam 11, cast-in-place shear wall 12, and cast-in-place floor slab 13. Traditional modular reinforced concrete structures have numerous module connection interfaces and require a large amount of concrete pouring on site, which weakens the advantages of modular construction technology and is not conducive to the promotion and application of modular buildings.
