Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a united / paneled stepped roof in a unit construction building or the like.

[0002]

2. Description of the Related Art Conventionally, as a roof structure for a pitched roof of a unit house or the like, a structure in which a roof panel is installed after a roof frame is assembled, and then a joint between roof panels is constructed. In general, a structure in which the entire roof is divided into a plurality of roof units to be produced in a factory, which is installed on site and then a joint portion between the units is constructed is generally adopted.

However, in the structure in which the roof panel is installed on the rooftop structure, the construction time is long and the man-hour is also large. Also, in the case of a roof with a corner that comes in and out that is complicated to fit in, the assembly work for that part is on-site work, so
There is a problem that it requires a professional job and takes time. on the other hand,
In the structure where multiple roof units are joined, a shed, a purlin, etc. are required for each unit in the adjacent portions of the units, and considering the roof as a whole, the members will be provided in duplicate. Material costs are high.

As a means for solving such a problem, a combination of a roof unit and a roof panel has been proposed. In this method, at least four corners of the roof are unitized, beams are bridged between adjacent units, and a roof panel is arranged on the beams.

However, the above proposed example is applied to a gable roof and the like, and in a stepped roof having a plurality of stepped roof surfaces, how to combine a roof unit and a roof panel, etc. Has not been devised. Even in general houses, there are many cases in which the plane of the building is concave, etc., and the pitched roof of such a building may have a difference in the ridge position between the wide part and the narrow part in the gable direction, resulting in a step on the roof surface. There are many. In that case, a wall surface will be created between roof surfaces of different heights, resulting in a complicated accommodation,
On-site construction takes time and effort.

An object of the present invention is to provide a stepped roof having a plurality of stepped roof surfaces, in which a labor saving, simplification, shortening of the construction period can be achieved, and a unit / panel combined stepped roof capable of reducing the materials used. Is to provide.

[0007]

The unit / panel combined stepped roof of the present invention is a stepped roof having a roof wall surface parallel to the gable surface in the middle of the girder direction, and is constructed as follows. Is. Roof units and roof panels are arranged alternately in the column direction. The roof panel is installed on the frame of the roof unit on both sides. At least a roof portion forming the end face and a roof portion forming the intermediate roof wall surface are formed by the roof unit. In this stepped roof, the width of the roof unit in the column direction is 0.5
˜2.5 times, and the width of the roof panel in the girder direction is 0.5 to 2.5 times the standard size, and the standard size is standardly used as the module width of a house. A width of 80-100 cm is desirable.

[0008]

[Function] Since the roof units and roof panels are alternately arranged and the roof panels are installed on the frames of the roof units on both sides, there is no need to separately provide a roof truss for installing the roof panels or a truss, and the materials used are reduced. In addition, it eliminates the need to assemble the hut structure on-site and simplifies construction. Since the arrangement direction in which the roof units and the roof panels are alternately arranged is the girder direction, unlike the case where the roof units are arranged in the slope direction, it is possible to eliminate the structural material dedicated to supporting the roof panels at all. Further, by using a large roof panel extending from the ridge to the eaves, it is possible to eliminate a horizontal seam in the middle of the roof slope and facilitate the rain scavenging treatment of the joint portion of the roof surface. In addition, the roof part that forms the gable face and the roof part that forms the middle roof part wall surface are composed of roof units, so the roof part that is complicated to fit due to the existence of the wall part will be unitized and factory manufactured. Therefore, despite the stepped roof, it is possible to eliminate complicated site work and save labor in the field work. That is, the work period can be shortened, the number of man-made objects can be reduced, and the number of steps can be reduced. Moreover, since the complicated interior part is manufactured in the factory, it does not require a professional and can be manufactured by multi-skilled workers, and the quality is high.

When the widths of the roof unit and the roof panel in the girder direction are set to the above-described dimensions, the dimensions are within the limits defined by the traffic rules, and the truck transportation from the factory to the site becomes possible. That is, the track width dimension is currently 2.5.
Although it is regulated within m, the standard size is 80
If the width of the roof unit and the roof panel is 0.5 to 2.5 times the standard dimension as a width of -100 cm, the roof unit and the roof panel can be transported within the limited width of 2.5 m as described above.
