BACKGROUND ART Conventionally, among building units constituting a two-story unit-type building, a larger floor area is secured within a building unit placed on an upper floor within a diagonal line limit stipulated by law. There is a trapezoidal box shape with an inclined surface on the top. Also, in recent years, the number of three-story houses is increasing, and even when building such houses by the unit construction method, by arranging a trapezoidal box-shaped building unit on the third floor, the floor area of that floor can be reduced. Larger reserves are being made within the tilt limits.

On the other hand, in a three-story building, it is obligatory to provide an emergency entrance having a width dimension of 750MM or more and a height dimension of 1200MM or more on the third floor portion. If the third floor portion is configured to include the trapezoidal box-shaped building unit, the trapezoidal box-shaped building unit may need to be provided with an emergency entrance. In such a case, it is common to provide the emergency entrance on a vertical outer surface continuous with the lower edge of the inclined surface.

By the way, in order to further increase the floor area, it is necessary to bring the building unit closer to the restricted diagonal line side. For this purpose, the area of the inclined surface in the trapezoidal box-shaped building unit is required. Must be larger. However, if the area of the inclined surface is increased, the area of the vertical outer surface becomes smaller, and there arises a problem that the emergency entrance having a predetermined size cannot be provided in the vertical outer surface. As a result, there was a limit to increasing the floor area on the third floor.

An object of the present invention is to provide a building unit capable of providing an emergency entrance and increasing the floor area.

In the present invention as described above, it is possible to provide the emergency entrance 8 of a predetermined size by utilizing the inclined surface 6, and by providing the emergency entrance 8 on the inclined surface 6, the area of the inclined surface 6 is increased. Even if it is increased, there will be no hindrance, so it is possible to secure a large floor area within the diagonal line restrictions. At this time, by providing an external floor 9 between the emergency entrance 8 and the inclined surface 6, the external floor 9 can be used as a step for the rescuer so that the rescuer can quickly enter. become.

Further, in the building unit of the present invention, it is desirable to provide the emergency entrance 8 on the vertical surface 7 which is located at a position recessed from the inclined surface 6. In such a case, it is possible to install the window frame 33, the shoji 34, or the door having a general opening / closing mechanism at the emergency entrance 8. That is, it is not necessary to provide the window frame 33 and the door in a tilted opening.

In the building unit of the present invention, the emergency entrance 8 may be a translucent glass window. In such a case, it becomes possible to incorporate daylighting inside the building unit 5A.

Further, in the building unit of the present invention, it is desirable that the outer floor 9 is horizontal. In such a case,
The rescuer can enter the area more quickly, and when the window or door provided in the emergency entrance 8 is destroyed at the time of entering, the fragments can be prevented from falling to the ground as much as possible.

Further, in the building unit of the present invention, a storage case 36 may be provided at least below the emergency entrance 8.
