Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a roof structure in a unit house.

Conventional technology In factory-produced housing such as unit housing,
Generally, roofs were constructed using standardized steel roof trusses, or bundles, beams, purlins, rafters, etc. were standardized, and these members were assembled to form roof frames.

In this way, for factory-produced houses where many of the components that make up the roof are standardized, building a house with a roof with a different external shape requires major changes to the roof structure, making it difficult to mass produce. I had the inconvenience of missing it.

Purpose of the invention The present invention was made in order to solve the above-mentioned conventional inconveniences, and its purpose is to provide a roof structure for unit houses that allows mass production of houses with different external shapes of roofs. purpose.

Structure of the invention The present invention forms a rectangular parallelepiped-shaped roof frame member by vertically suspending pieces at the corners of a roof panel receiving part formed in a rectangular planar shape, and this roof frame member is used as a building frame for a house. The lower end of the vertical piece is fixed to the beam in the upper surface by placing it in the center of the upper surface, and a plurality of The above object is achieved by extending the roof panels to form an outer roof, and by placing and fixing a central roof unit forming the roof apex above the roof panel receiver.

Embodiments of the invention Hereinafter, embodiments of the invention will be described based on the drawings.

In the embodiments shown in FIGS. 1 to 4, the basic roof type is a gable roof.

The basic roof structure of a gable roof will be explained based on FIGS. 1 to 3.

An outer roof 71 is formed.

Between the upper edges of the outer roofs 71, 71, that is,
A central roof unit 91 forming the ridge of the gable roof is mounted and fixed on the upper part of the roof panel receiving part 31.

Although the basic gable roof is constructed in this way, it is shown in FIG. 4 that by changing the external shape of the central roof unit 91, it is possible to construct a wide variety of modified roofs. A to F
The explanation will be based on.

The modified roof shown in the figure is constructed by using the aforementioned gable roof as a basic roof and changing the central roof unit 91.

In Fig. 4A, a modified roof is constructed by adding a central roof unit 91a with a lighting window 4a or a ventilation system protruding from the center of the central roof unit forming the ridge of the gable roof mentioned above. Show what you did.

FIG. 4B shows a double gable roof in which the central roof unit 91 forming the ridge of the gable roof described above is placed and fixed with a step 4b provided between it and the outer roof 71. It is.

FIG. 4C shows a central roof unit 91 in which a smaller gable roof 4C is protruded from the center of the central roof unit forming the ridge of the gable roof described above.
Indicates C.

In FIG. 4D, the roof on one side of the central roof unit 91d is formed as a roof surface with the same slope that is continuous with the outer roof 71, and the roof on the other side is formed as a vertical roof surface 4d,
A roof is shown in which a lighting window is provided on the vertical roof surface 4d.

FIG. 4E shows a roof in which the central roof unit 91e is formed into a flat roof, and the top of the gable roof is made into a flat roof surface.

FIG. 4F shows a roof in which the central roof unit 91f has a hip roof type.

Next, other embodiments shown in FIGS. 5 to 9 will be described.

In this embodiment, the basic roof type is a hipped roof, and the roof structure of the basic hipped roof will be explained based on FIGS. 5 and 6.

In the figure, 22 indicates a roof frame member, and this roof frame member 22 is formed by joining section steel into a rectangular planar shape to form a roof panel receiving portion 32, similar to the above embodiment. Roof panel receiving part 3
Vertical pieces 5a, 5a... are hung from the corners of 2,
It is formed into a rectangular parallelepiped shape.

The roof frame member 22 is placed in the center of the upper surface of the housing frame 1, and is mounted on the vertical pieces 5a, 5a...
, the inner beam 1 on the upper surface of the housing frame 1
It is fixed to C by bolt connection or the like.

The edge of the roof panel receiving part 32 of this roof frame member 22 and the beams 1 on the long side and short side of the housing frame 1
A plurality of roof panels 6, 6... are stretched between a and 1b, and an outer roof 7 is formed on all sides of the roof frame member 22.
2 is formed.

The outer roof 72 is formed with a hipped roof by extending triangular roof panels 6a, 6a, . . . at the corners where the long side roof surface and the short side roof intersect.

Between the upper edges of the outer roof 72, that is, above the roof panel receiver 32, a central roof unit 92 forming the ridge of the hipped roof is mounted and fixed.

Although the basic hipped roof is constructed in this manner, it is possible to construct a wide variety of modified roofs by changing the external shape of the central roof unit 92. Diagrams A to F
The explanation will be based on.

The modified roof shown in the figure is a modified roof constructed by using the aforementioned hipped roof as a basic roof and changing the central roof unit 92.
