Description

Modular construction and installation process

Technical Field

The invention relates to the technical field of machinery, in particular to a modular building and installation process.

Background

The traditional modular building composed of containers mostly has only two layers of containers. The upper and lower decks of containers are typically secured by twist locks attached to standard corner fittings of the upper and lower decks of containers, but twist locks cannot be attached to adjacent containers on the same deck.

Along with the continuous development of market, in order to satisfy the supporting needs of modular building, novel modular building now is mostly the container crowd that the multilayer container that is no less than two-layer makes up to wherein each layer also comprises many containers. However, the conventional way of connecting corner fittings by using twist locks cannot connect adjacent containers on the same layer, and has the defect of low structural strength. Therefore, the modular building adopting the traditional connection mode cannot meet the requirement of seismic intensity of a project site.

Therefore, a modular building which is connected by inserting the upper and lower layers of containers into the connecting rods through slot hole sites is appeared in the market. However, based on the existing box manufacturing precision, it is often found that the difference value of the diagonal lines at the ends of the boxes is large, so that hole positions at the top and the bottom are offset to a certain extent, and therefore, the hole positions at the upper layer and the lower layer are often found to be not aligned to each other in the stacking of the boxes on site, abnormal processing such as hole expansion needs to be performed on parts such as connecting plates, and the like, so that the field working strength and the construction safety hazard are increased, and the slow progress of the stacking of the boxes and.

Therefore, there is a need for a modular construction and installation process that at least partially addresses the above problems.
