Patent ID: 8499527

Claim:
A building construction method for constructing a building, comprising: manufacturing, in a plant, a plurality of rectangular room modules, each with a steel frame structure, including the following steps: connecting beams into a rectangular steel frame, to create a ceiling frame of a rectangular room module, connecting a frame column member to each corner of the ceiling frame, connecting vertical column members to the ceiling frame, wherein said vertical column members do not include said frame column members, connecting beams between vertical column members, between frame column members, and between frame column members and vertical column members, so as to create walls of the rectangular room module, fitting steel plates in empty spaces in the walls of the rectangular room module, each empty space in a wall being framed by: beams, and either two vertical column members, or a vertical column member and a frame column member, rotating the rectangular room module so as to dispose the ceiling frame of the rectangular room module above the walls of the rectangular room module, fitting a deck plate or a reinforcing steel member in each empty space in the ceiling of the rectangular room module, each empty space in the ceiling being framed by beams, and placing mechatronics equipment in rectangular room modules, said mechatronics equipment including at least one of: piping, ducts and cables; transporting the rectangular room modules from the plant to a building construction site; installing the rectangular room modules in a grid pattern, including creating a frame column of the building by connecting four frame column members adjacent to one another, wherein each frame column member is from a different rectangular room module, and wherein each frame column member is vertically provided at a corner of one of a plurality of adjacent rectangular room modules; placing concrete on the ceiling of a rectangular room module, thereby enabling the ceiling of the rectangular room module to act as a floor surface of another rectangular room module installed thereon; and placing concrete in a space in a rectangular parallelepiped shape, which is longer in a vertical direction than in any other direction, the rectangular parallelepiped shape formed by connecting adjacent frame column members with steel plates so as to make the frame columns of the building have a steel plate concrete structure.
