Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building unit with a pitched roof frame, and can be used in a box-shaped unit type prefabricated building used for houses and the like.

[0002]

2. Description of the Related Art Conventionally, a unit type prefabricated building has been used as a building such as a house with high performance, high quality, low cost and a short construction period. Some of these unit-type buildings are relatively conventional buildings that assemble panels and shafts that have been factory-manufactured to a specified shape and dimensions, but in recent years, building units that have been assembled into rectangular parallelepiped box shapes at the factory. A box-shaped unit system that forms a building by combining is widely used.

Among them, the box-shaped unit system is a frame panel system in which inner and outer panels are stretched on a frame in which steel frames or the like are combined in a rectangular parallelepiped shape as columns or beams, and the panel itself is assembled on each surface of the rectangular parallelepiped. The panel monocoque method that secures the structural strength is used.

Although the roof of a unit type building is partially flat, it is generally a flat roof type, but a pitched roof is generally used for residential purposes. Among the unit type buildings, as the pitched roof in the frame panel system, the roof panel system and
The roof unit method is used. In the roof panel system, a receiving structure such as a bundle pillar is erected on the upper surface of the uppermost floor portion composed of the above-mentioned box-shaped unit, and a roof panel having a surface finished for roof is assembled thereon. In the roof unit method, a roof panel and a supporting structure including a bundle pillar are assembled in a factory in advance and placed on a unit on the uppermost floor of the building on site.

[0005]

Here, in the roof panel system, since each member before assembly is compact, it can be easily and simply transported. On the other hand, the roof panel method requires assembling from the supporting portion at the site, which requires a large number of assembly steps and inevitably complicates site construction. On the other hand, the roof unit method is generally assembled in a factory, and after mounting on the top floor unit at the site, all that is required is waterproof connection of the joint, etc., and the site construction can be simplified and speeded up. On the other hand, the roof unit method has a disadvantage that it has to be carried into the site as a three-dimensional unit, requires a large amount of transportation from the factory, and requires an additional number of trucks.

An object of the present invention is to provide a building unit with a pitched roof frame that can simplify both on-site construction and transportation.

[0007]

The present invention is characterized in that a roof frame for supporting a pitched roof is provided on an upper portion of a rectangular parallelepiped box-shaped main body frame. Here, the main body frame is a frame of a box-shaped building unit in the shape of a rectangular parallelepiped, and is assembled by a steel beam or the like. An outer wall panel such as ALC (lightweight cellular concrete) is appropriately stretched on the outside of the main body frame, and interiors such as walls, floors, ceilings, and furniture, etc. are appropriately installed inside.

The roof frame includes a bundle member that rises from the upper surface of one side of the main body frame, and an inclined member whose one end is supported by the bundle member and whose other end is supported by the upper surface of the other side of the main body frame. Is desirable. .
It is preferable that the roof frame includes opposing bundle members that stand up from one side upper surface and the other side upper surface of the main body frame, and a mountain-shaped member whose one end and the other end are supported by each bundle member. .

It is desirable that the roof frame is connected and fixed to the upper surface of the pillar portion of the main body frame. . The bundle member is preferably formed by an extension of a pillar of the main body frame. .

[0010]

In the present invention as described above, since the roof frame is installed in advance at the factory on the upper surface side of the rectangular parallelepiped building unit including the main body frame, the building unit with the roof frame is carried to the site and the uppermost floor of the building is loaded. If installed in the part,
The roof frame will be installed on the upper part of the building as it is.

Therefore, at the site, the roof can be formed only by arranging the roof panel on the roof frame on the upper part of the building, and it is not necessary to assemble the roof support structure unlike the conventional roof panel system, and the conventional roof unit is used. It is not necessary to place the work on the building unit like the method, and the on-site construction can be simplified. Further, in transportation, since the roof frame and the main body frame can be integrally handled as a building unit, there is no need to transport the roof frame separately from the building unit as in the conventional roof unit system, and transportation can be simplified.

Further, if the roof frame is composed of a bundle member and a sloping member facing in one direction, a roof support structure on the eaves side of the roof can be constructed. Can be configured. When the bundle member is connected and fixed to the pillar portion of the main body frame, the load strength can be secured, and when the pillar of the main body frame is extended to form the bundle member, the connection and fixation can be omitted and the rigidity can be increased.
