"Steel Frame Modular Unit Housing" is a technology that systemizes high-quality housing to ensure the recycling of resources, while securing a certain quality and supplying it to many customers. In order to achieve this, a box-type steel frame with a high degree of completeness is required to be produced in the factory, and a technique is required to be completed in a short time by a minimum process in the field.

The steel-frame unit modular housing is less suitable for factory production and less loss, and it is the most suitable housing production method for reuse and recycling.

However, in the related art, the columns and the beams are joined by a joining method such as brackets and welding. This is not only the stress transmission is unclear, but also problems such as heat deformation due to the steel plate, the increase in the amount of bolts and the excessive amount of welding, and there is a problem in that the efficient use of the column member due to the overlap of the column section when the modular unit is horizontally coupled.

As a background of the present invention, there is a patent registration No. 0923637, "Architectural modular unit having reinforced connection structure" (Patent document 1).

However, in the background art, the upper modular unit and the lower modular unit are combined using the connecting plate 20. Since the structure simply couples the ends of the pillars to each other, it is difficult to increase the lateral force resistance and maintain structural stability. In addition, there is a problem in that the vertical coupling and horizontal coupling are very difficult because the coupling structure is complicated and the coupling is not exposed when the coupling between the modular units is performed.
