2. Description of the Related Art In recent years, a unit construction method has been adopted in a building such as a house for the purpose of shortening a construction period at a building site. This is a method of manufacturing various housing units such as a room box unit and a roof unit in a factory in advance and transporting them to a construction site, where they are installed on a foundation to build a unit house.

[0003] By the way, when a room such as a solarium is to be provided so as to protrude from a building body by such a unit construction method, conventionally, in a factory, it corresponds to the protruding portion using columns or beams. Manufactures a rectangular overhang unit and transports it together with the box unit to the construction site, where it is assembled to the box unit, or the frame is assembled using columns and beams at the construction site It is known from a method of assembling this to a building body to form an overhang portion.

[0004]

However, in any of the conventional methods, the room of the overhang portion is made up of four pillars and four lower beams connecting the lower ends of the four pillars, The structure has at least two (two beams connecting the front and rear columns) connecting the upper ends of the four columns. Therefore, when the overhanging unit is attached to the box unit, the pillars of the box unit and the pillars of the overhanging unit overlap, which leads to waste of material costs, which is a factor of cost increase. .

[0005] It is an object of the present invention to eliminate the above-mentioned drawbacks of the prior art, reduce costs without wasting material, and ensure strength that can withstand vibration during transportation.
An object of the present invention is to provide an overhang unit that can be maintained and can be joined to a box unit with high positional accuracy.

[0006]

Therefore, the overhanging unit of the present invention is manufactured in a factory, and is composed of four columns and a plurality of beams connecting between upper ends and lower ends of these columns. For building sites with box units configured in a box shape

[0007]

The floor frame has both base ends connected at right angles to the two columns of the box unit, and the ceiling frame has both base ends connected at right angles to the two columns of the box unit. , Because it consists of two pillars that connect both free ends of the floor frame and ceiling frame,
In other words, the pillars that overlap the pillars of the box unit are omitted, so that material costs can be reduced compared to the past,
As a result, cost can be reduced. In addition, the floor frame and ceiling frame are framed in a rectangular shape by four beams .
In addition to ensuring the strength to withstand vibrations, etc., applied to the two columns of the box unit, the positions on both sides of the base end, that is, the positions of the base ends of the beams on both sides constituting the framework of the floor frame and the ceiling frame are also required. Since the interval between them is accurately set by the beam connecting them, it is possible to join the box unit with high positional accuracy. Moreover, since the floor frame is formed in a rectangular frame, the required strength of the floor can be secured.
