DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof structure and an eaves roof unit in a house or other unit building.

[0002]

2. Description of the Related Art Conventionally, as a roof structure of a unit house,
Generally, a configuration is adopted in which a plurality of mountain-shaped roof trusses are provided in parallel in the row direction, a roof panel is mounted on these roof trusses, and a finishing material such as a roofing material is provided.
Eaves gutters and gables are also installed on site. In some cases, the roof is divided into several triangular boxes, factory-produced, transported to the site, and joined to form a unit roof.

[0003]

The above-mentioned unit roof type has a high factory production rate and requires relatively little on-site work. However, since a three-dimensional roof unit is transported to the site, it has to be transported. ineffective. In addition, it is necessary to divide the roof unit into small roof units due to the size restrictions in the Road Traffic Law, and the number of units increases and the number of trucks increases. For these reasons, transportation costs increase. In addition, since the roof unit is divided into a large number in this manner, the number of work for processing the connecting portion on the site increases. In addition, the division of the roof unit is also performed in the direction of the wife, and a large number of inter-unit connecting portions extending in the lateral direction (row direction) are formed on the roof surface. The horizontal connection of the roof surface is more difficult to finish raining than the connection in the vertical direction (along the roof gradient), and is a cumbersome and time-consuming operation. For this reason, even if a unit roof type is adopted, it is difficult to obtain the expected labor saving effect of on-site construction, and it is disadvantageous in terms of cost and the like when comprehensively judged. Often used as a roof.

In the truss-type roof, since all of the truss-type roofs are composed of flat parts, the transportation efficiency is higher than that of the unit roof type. However, all conventional truss-type roofs use a roof truss parallel to the wife's face, so the roof truss has a mountain shape or a triangular shape obtained by dividing the mountain into two. For this reason, space efficiency cannot be sufficiently improved in truck transportation and storage. In the case of a conventional truss-type roof, since eaves ceilings, eaves gutters, gables, and other small parts are also constructed on site, the construction takes time and the construction period is lengthened. In addition, the mounting of these small parts involves a lot of work at a high place and is dangerous, and requires a scaffold. In unit-construction houses, a configuration has been developed that allows most of the construction to be performed without the need for a scaffold.In such a configuration, the scaffold is built only for processing the eaves, which is inefficient. .

It is an object of the present invention to provide a roof structure and an eaves roof unit that can efficiently transport and store constituent members to a site and that can be easily installed at the site.

[0006]

A roof structure according to the first aspect of the present invention is a roof structure of a sloped roof constructed on juxtaposed unit boxes, wherein the roof structure comprises a vertical frame-shaped ramen or truss extending in a girder direction. Are provided at a plurality of locations separated in the direction of the wife. The bundles at both ends of any of the roof frames are installed on pillars of a unit box.

In this configuration, it is preferable to provide an eaves roof unit projecting laterally along the girder row direction at the upper end of the unit box. The eaves roof unit shall have an eaves frame and an eaves ceiling. It is preferable to install a large roof panel extending from the ridge to the eaves on the roof frame. When the eaves roof unit is provided, a large roof panel extending from the ridge to the eaves is installed over the roof frame and the eaves roof unit.

[0008] The roof structure of the invention of claim 5 is applied not only when the building body is a unit box. According to the present invention, a plurality of roof frames composed of vertical frame-shaped ramen or trusses extending in the girder direction, an eave roof unit having an eave frame, and an eave roof unit and an eave roof unit on the roof frame and eave roof unit from the ridge to the eaves. An extended roof panel. The roof frame is provided at a plurality of locations separated in the direction of the wife.

The eaves roof unit of the present invention is of a foldable type and is provided with a roof panel or the like thereon. That is, the eaves roof unit has a building frame joint at the upper end and extends along the roof slope, and is attached to the eaves of the inclination frame so as to be able to turn up and down and below the inclination frame. An eaves ceiling frame that can be folded in an overlapping state, a support frame whose lower end is attached to the eaves ceiling frame so that it can be folded in a folded state and an upper end can be joined to the inclined frame, and an eaves ceiling surface stretched on the eaves ceiling frame And a gutter provided along the eaves of the inclined frame or the eaves ceiling frame.

[0010]

In this roof structure, since the roof frame is a vertical plane ramen or truss extending in the girder direction, these roof frames are rectangular flat parts. Therefore, transportation and storage in the factory can be performed with a good space efficiency. In addition, when the roof frame extends in the girder direction as described above, it is easy to have a size that can be bridged between both ends in the longitudinal direction of the unit box, and the structure combined with the unit box is simple and simple. Therefore, roof design is easy. In the case where the bundle material at both ends of the roof frame is installed on the columns of the unit box, the roof load is directly supported by the columns of the unit box, so the roof load does not act on the ceiling beam,
The margin of the ceiling beam can be afforded.

When an eaves roof unit having an eaves frame and an eaves ceiling is mounted on the upper end of the unit box, the eaves frame, which is likely to have a complicated structure, can be easily attached only to the unit box. Can be constructed on site. In addition, the on-site ceiling construction is not required. Since the eaves roof unit is relatively small, there is relatively little transportation efficiency problem even with a three-dimensional shape.

When a large roof panel extending from the ridge to the eaves is installed on the roof frame, no lateral joints are formed on the roof surface, so that on-site construction becomes easier. The roof panels are factory-fabricated with the roofing material, which is the finishing material, so on-site work is completed only by installing the roof panels and treating the joints between the vertical roof panels with rain. , Construction becomes very simple.

In particular, when the large roof panel extending from the ridge to the eaves and the eaves roof unit are combined with the roof frame, the construction work at the site is very simple, and the roof is not required. The components need only be planar parts except for the eaves roof unit. For this reason, while most of the components are planar components, the efficiency of transportation and storage can be improved, and on-site construction that does not differ from that of the conventional unit roof type can be performed. Therefore, by combining this roof structure with the unit construction building, it is possible to improve the transportation efficiency without impairing the effect of shortening the construction period, which is the greatest advantage of the unit construction method.

[0014] In a building of another construction method, such as a building of a panel construction method or a frame construction method, a unit construction method building may be used.
By adopting this roof structure as in the above configuration, the efficiency of transportation and the ease of on-site construction can be improved.

In the eaves roof unit according to the sixth aspect, the inclined frame, the eaves ceiling frame, and the support frame are configured to be folded on each other, so that they can be transported and stored in a planar state, and the transportation and storage efficiency can be reduced. good. In addition, since the eaves ceiling and gutters were provided in advance, on the site, after returning to the three-dimensional shape from the folded state by ground work, this eaves roof unit was simply attached to the building body such as a unit box, and almost all Construction of the eaves section is completed. Therefore, complicated high-place work is not required, and the construction of the eaves can be completed without using a scaffold.
