DESCRIPTION OF THE PREFERRED EMBODIMENTS The eyebolt fastening structure of a typical unit house according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is an explanatory view (cross-sectional view taken along the line EE in FIG. 3A) showing an eyebolt fastening structure of the unit house A, which is a hollow square steel material 1, a through bolt 2, and an eyebolt 3 which form a frame. , And the flat bar 4.

Each unit house A is shown in FIG.
As shown in (b), the lower unit house A ₁ and the upper unit house A ₂ are connected vertically, horizontally, and longitudinally to form a collective building α, and FIG. FIG. 3B is a perspective view of a collective building α formed by two rows on the left and right sides and two stages on the upper and lower sides, for a total of four units, from the front side and FIG. 3B from the back side.

A unit house A, which is connected to form an aggregated building α, is mainly a hollow rectangular steel material 1 serving as a frame to form a frame, and is formed into a horizontally long cube or the like. In addition, in this cube, the entrance door 5, window 6, bay window 7,
The balcony 8, the outer wall 9, the floor 10, and the ceiling 11 with a roof are formed, and a ventilation fan, an air conditioner, etc. are installed if necessary. This is a shape suitable for transportation from the factory to the installation site, and by making it a cubic shape,
This is for facilitating loading and unloading of the truck with a crane and for facilitating connection of the unit houses A.

Further, the outer wall 9 is made of a lightweight and highly earthquake-resistant material that can withstand the impact and vibration of truck transportation.
For example, a metal siding, a metal panel or the like is used. Note that the roofed ceiling 11 may be a roof material that is widely used, and may be waterproof. Of course, a base material having functions such as heat insulation, soundproofing, sound insulation and fireproofing can be formed on the roof (ceiling), outer wall, floor and the like.

Further, the unit house A is a floor 1 on the entrance side.
0 is extended to form the passage 12. This passage 12 can be extended to the left and right simply by connecting the unit houses A to the left and right, and especially in the case of a building with two or more floors, there is no need to separately form the passage on the site, and the construction period is shortened. This makes the construction easier. In addition, passage 12
A handrail 13 is formed at the end edge of the to project vertically to prevent danger. Of course, stairs leading to the second floor (plural floors), handrails for fall prevention, and the like, which are needed depending on the assembled shape of the collective building α, are separately attached.

Further, the eyebolts 3 are to be installed on the rectangular steel material 1 which constitutes the roof 11 of the unit house A, and are formed at at least four corners to keep the crane loading and unloading in a balanced manner.
