Description

A staggered modular building structure and its construction method

Technical field

The invention relates to a modular building structure, in particular to a staggered modular building structure, and also relates to a construction method of the staggered modular building structure.

Background technique

Modular building is an emerging building structure system. This system uses each room as a modular unit (it can also combine various partitions of the house into a modular unit according to the actual situation, taking a single apartment as an example, corridors, balconies , rooms, and bathrooms can be combined into one modular unit). Each modular unit is prefabricated in the factory, and the internal space of the module can be arranged and decorated in the factory. After completion, it is transported to the site and assembled into the entire building through reliable connections. , such as a modular building with a central structure (such as a core tube). The central structure (such as a core tube) is usually constructed on site. The core tube can be a reinforced concrete structure poured on site, or it can be a steel structure or a steel-concrete combination. Structure, each unit module and between the unit module and the core tube are all assembled into the building as a whole through reliable connections. Building modular units are usually self-contained and require little on-site craftsmanship, thus significantly reducing on-site work time. Compared with traditional building construction methods, modular buildings have the advantages of shortening the construction period, saving manpower and material resources, being green and environmentally friendly, and having excellent quality.

However, existing modular buildings still have the following shortcomings: Modular buildings are commonly known as box buildings, that is, each unit module is similar to a box with six sides, because modular buildings are stacked by box-shaped unit modules. Therefore, there will be many repeated surfaces between adjacent unit modules. The columns, beams, floor slabs, internal partition walls, etc. between adjacent unit modules overlap. Generally, they can be reused twice or more. Not only does it cause unnecessary waste, but it also causes the construction cost of modular buildings to double compared with conventional building structures, making it difficult to promote modular buildings.
