The most on-the-spot Module nodes to key is attached, and forms the rigidity that structure is overall, next to that make building
The seam crossing of intermodule coincide, it is ensured that the building demands such as safe, waterproof, sound insulation and anticorrosion.
It addition, because the restriction transported, lift by crane and install, for the facility producing, transport and installing, build
Built module is usually formed as cuboid.The length on the long limit of building block is up to approximately 18 meters, the length of minor face
Degree be up to approximately 4.5 meters, the height of building block be building monolayer height, i.e. 3.1 meters to 4.5 meters it
Between.

It addition, in corner post bearing type building module, the joist of superstructure module and substrustion module
Variola plate-girder separate, two beams bear alone the load on vertical direction, do not have combined effect between beam, because of
Overall inefficient of this structure.In order to improve the support loads of building block, need to strengthen joist and sky
The size of card beam, thus steel quantity consumption becomes big.By calculating, the steel quantity consumption of columns supported modular structure is
The 120% to 130% of the steel quantity consumption of same steel construction, its main cause is exactly that the steel quantity consumption of long side bar is bigger.
Further, since for the support loads improving building block, need to strengthen joist and variola plate-girder
Size, so the depth of section of joist and variola plate-girder is relatively big, typically between 150mm to 300mm, adds
Installation gap necessary between upper module and floor thick-ness and ceiling thickness, lower floor's ceiling is to upper strata
Floor spacing is generally higher than 400mm, the most significantly decreases user indoor use height, was built into once
This is higher.
