Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a roof unit and a unit building.
[0002]
[Prior art]
Conventionally, in a unit building, as described in Japanese Patent Publication No. 3-26745, a plurality of building units are joined and a roof unit is mounted on each building unit.
[0003]
[Problems to be solved by the invention]
In the prior art, when a different roof is formed on a single building unit, if the upper roof surface and the lower roof surface are configured as separate roof units, the vertical load acting on those roof surfaces In order to transmit the horizontal load to the building unit side, it is necessary to provide a beam and a wall for supporting the roof units immediately below the boundary between the two roof units on the inner side of the building unit. For this reason, the freedom degree of a floor plan inside a building unit and a feeling of opening are spoiled.
[0004]
An object of the present invention is to improve a degree of freedom and a feeling of openness in a floor plan of a building unit when a different roof is formed on the building unit.

The long roof units 23 and 24 are mounted.
[0013]
The roof unit 23 constitutes the different roof 2 on the building unit 13, and has an upper roof surface 31 and a lower roof surface 32, and the upper roof surface 31 and the lower roof surface 32 are those The upper roof surface 31 and the lower roof surface 32 have their gradients opposite to each other. The roof surface 31 on the roof unit 23 intersects the roof surfaces 21A and 22A of the roof units 21 and 22, and is continuous with the roof surface 24A of the roof unit 24. The roof surface 32 under the roof unit 23 intersects the roof surface 24A of the roof unit 24.
[0014]
FIG. 2 shows the building unit 13 and the roof unit 23 taken out. The building unit 13 includes an inner wall panel 13B and an outer wall panel 13C at opposite side edges of the floor panel 13A, and a sleeve wall 13D that intersects the outer wall panel 13C at the other one side edge of the floor panel 13A.
[0015]
As shown in FIGS. 2 to 5 (in FIG. 3B, FIG. 4 and FIG. The lowermost edge and the uppermost edge of the lower roof surface 32 are made the same height, the upper roof surface 31 and the lower roof surface 32 are supported by an integral truss beam 33, and both ends of the truss beam 33 are built. The unit 13 is connected to the inner wall panel 13B and the outer wall panel 13C. Further, the roof unit 23 is configured such that, on the back side, the uppermost edge of the upper roof surface 31 is raised from the lowermost edge of the lower roof surface 32, and the upper roof surface 31 is supported by the truss beams 34. Both ends of 34 are connected to the inner wall panel 13B and the sleeve wall 13D of the building unit 13.
