Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unit structure roof constructed by combining roof units.

[0002]

2. Description of the Related Art Conventionally, in a unit structure building, the roof is often a unit structure. In this case, in a gabled roof with a gable or the like, the entire roof is divided into a plurality of roof units 71 in the gable width direction as shown in FIG. These roof units 71 have a planar shape of the same size as the room unit 72 therebelow, and are stacked on the room unit 72 and joined by bolts or the like.

[0003]

However, in such a conventional roof structure, the height h of each roof unit 71 becomes higher toward the center of the ridge because of the roof slope. Therefore, when the span L of the entire roof in the wife direction is long, or in the case of a steeply sloped roof, the height h of the roof unit 71 in the ridge portion becomes too high to fall within the height limit of the Road Law for truck transportation. It may not be able to be transported. In addition, if the height h becomes high, even during the manufacturing process of the roof unit 71 in the factory, it will be out of reach of the worker, and the workability will deteriorate. Further, since each roof unit 71 is directly stacked on the unit box 72 therebelow, the bundle 73 becomes long in the roof unit 71 of the ridge, and the amount of material used increases, which is uneconomical.

Further, in the unit-structured roof shown in FIG. 1, a large number of bundles of the roof units 71 and the ceilings appear in the back of the hut, which limits the design of the hut storage space. Also,
When the ceiling surface is arranged above the lower surface of the roof unit 71, bundles, beams and the like project, which makes it difficult to provide such a large space in the building. In addition, as described above, there are many bundles and threads on the back of the cottage, which makes it difficult to perform various operations in the cottage during construction and maintenance.

The object of the present invention is to make it possible to reduce the height of each roof unit even in the case of a large span, to meet the size limitation in transportation, and to provide a large space in the attic without protrusions such as columns. (EN) Provided is a unit structure roof which can be formed, facilitates the design of an attic storage room and the formation of a large space with a high ceiling, and can perform roof construction safely and easily.

[0006]

A unit structure roof of the present invention comprises a pair of eaves side roof units, and a ridge side roof unit which is placed between the eaves side roof units and constitutes an upper part of the gable roof. Composed of. Eaves side roof unit is adjacent to the upper edge of the roof surface with a slope have a horizontal roof unit receiving portion is intended side shape is trapezoidal, the pair of eaves side roof unit is facing away from each other To do. Each of the eaves-side roof units is a unit box frame provided with a surface material for a roof surface, and the roof unit receiving portion is configured by a part of the unit box frame to have a surface material for the roof surface. a portion of the horizontal member which is not stretched, and you shall edges wife direction is supported by each beam member. Of the horizontal material that will be the roof unit receiving part
The parts are located along both edges of the roof unit receiving part in the gable direction.
Two parallel girder horizontal cross members and these girder horizontal cross members
It is composed of a plurality of laterally-stretched materials that connect the spaces. Upper Symbol ridge side roof unit shall be constructed Put the face plate of the roof in the unit box frame. The roof surface of the eaves side roof unit and the ridge side roof unit shall be continuous without a step.

On the roof side of the roof, a rectangular portion is opened between a pair of eaves side roof unit and ridge side roof unit, but a side wall panel may be provided in this opening. In addition, when partitioning the back of the hut with a boundary wall, the eaves side roof unit and the ridge side roof unit on both sides are provided with unit inner boundary walls,
A panel behind the hut wall will be installed to connect to the inner wall of these units. The eaves side roof unit may be provided with hanging tool mounting holes for removably mounting the lifting tool on the front and upper surfaces of the eaves and on the upper surface of the roof unit receiving portion, respectively.

[0008]

According to this structure, since the ridge-side roof unit and the eaves-side roof unit are formed in upper and lower two stages, the height of these roof units does not become so high even if the span in the gable direction becomes long, It is possible to fit within the transportation size limit. When constructing roofs having different spans, it is possible to prepare the same eaves side roof unit and make only the ridge side roof unit having a different span. Even if the span of the ridge-side roof unit is increased, the height of the ridge-side roof unit can be kept within a predetermined limit in a typical house or a building such as an apartment. Moreover, since the height of the ridge side roof unit is reduced by the height of the eaves side roof unit,
The length of the bundle material etc. can be short, and the material can be saved.

Also, since the eaves side roof units on both sides are provided apart from each other and the ridge side roof units are laid over them,
In the back of the hut, a wide space is formed below the roof unit on the ridge side without protrusions such as columns. Therefore, it is possible to freely design an attic storage room or the like using this space, and it is also possible to form a large space with a high ceiling following the attic space in the building. Furthermore, when performing roof construction,
Workers can move and work in the large attic space, and workability is good.

When the end wall panel is provided on the end face of the roof as described above, it is easy to carry out site construction for closing the end face. Also,
When the boundary wall is composed of the unit inner boundary wall provided in each roof unit in advance as described above and the attic wall panel, the entire attic wall can be easily constructed.

The eaves side roof unit can be transported by truck, for example, by arranging a pair of eaves side roof units in a standing posture with their lower surfaces facing each other. Can fit exactly into the truck transport limit size.
