Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a building using a steel bearing wall panel made of a steel frame and a wooden face material. The wall structure is a steel house structure, and a wooden frame material and a foamed resin-based heat insulating material are used for the roof structure. The present invention relates to a connection structure between a wall construction surface and a roof construction surface when a structural heat insulation panel sandwiched between face materials is used. A steel house is a wall-type structure among thin, lightweight steel structures. A thin lightweight steel is a steel structural material having a wall thickness of less than 2.3 mm.
[0002]
[Prior art]
As a basic structure of a building using a steel wall panel, there is a technique in which a through member is attached to the upper part of a wall construction surface constructed by connecting and fixing a load-bearing wall panel, and a roof truss is installed on the upper part (for example, (See Patent Document 1). This technology does not consider using the hut as a living space.
[0003]
In addition, in a wooden house, there is a basic structure of a building using the same wall panel in a wooden structure. This structure is a structure in which a wall set framed in a factory is assembled by screwing, a roof is screwed to a ceiling joist panel, a roof truss and a roof panel, and a siding is alternately engaged with a mounting bracket on an outer wall (for example, (See Patent Document 2). In this structure, it is difficult to join the wall construction surface and the roof panel with structural continuity in the building where the wall construction surface and the roof truss use steel frame materials, and ceiling joists are installed on the ceiling surface. Therefore, it becomes difficult to construct a wide space that has continuity with the immediate lower floor.
[0004]
Various roof structures using the hut as a living space are also disclosed. For example, there is a structure in which a roof panel is supported by a large number of bundle members and a triangular truss (see, for example, Patent Document 3). In this technique, a triangular truss is required between the bundling material for supporting the roof construction surface and the outer wall and the space behind the shed, and there are beams and walls or columns that support the bundle and the triangular truss on the floor directly below the shed. is necessary. Therefore, although the cabin space can be used, the space on the lower floor is limited. Moreover, the number of members and the number of joints increase, and the construction becomes complicated.
[0005]
In addition, there is a structure in which a floor construction surface is once formed immediately below the roof and a triangular truss and partition walls are arranged on the back of the hut (see, for example, Patent Document 4). In this structure, there are many structural surfaces that constitute the back of the hut, and the construction becomes complicated, and it is difficult to configure a wide space having continuity with the lower floor. Moreover, the number of members and the number of joints increase, and the construction becomes complicated.
[0006]
The space between the truss is widened to form the attic space, and there are extremely few points that support the load from the roof, and there is also a structure that is supported by the truss and roof beam assembly frame, bundle material, and receiving material attached to the bundle material (for example, , See Patent Document 5). In this structure, an excessive load acts on a beam provided directly under the truss. Although the number of members is small, it is necessary to improve the member strength to receive an excessive load.
[0007]
There is a hut truss that also serves as a ceiling structural member in the shed space and a wall structural member in the shed space (see, for example, Patent Document 6). With this technology, only a rectangular long and narrow space can be secured in the back of the hut, and a wide space having continuity with the immediate lower floor cannot be formed as described above.
[0008]
It is difficult to effectively use the attic space with the conventional techniques as described above. On the other hand, as a roof panel capable of reducing the installation of trusses, roof beams and the like as much as possible, there is a structural heat insulating multi-layer board in which a wooden frame material and a foamed resin heat insulating material are sandwiched between wooden surface materials. For example, the R control panel developed by AFM in the United States is a structural surface material “OSB (Oriented Strand) that is press-molded with adhesives using hardwood and aspen as chips with EPS (foamed polystyrene) as the core material. There is a panel having a sandwich panel structure in which “board” is bonded from both sides (for example, see Non-Patent Document 1). When the roof panel having such excellent strength is used, the truss and the roof beam can be reduced as much as possible.

【The invention's effect】
According to the present invention, it becomes possible to use a heat insulating multilayer board for a wooden structure incorporating a heat insulating material for a roof construction surface, and a wide interval can be taken using a triangular frame mainly for a wife surface, There is no exposure of structural members in the attic space, and the living room space can be extended to the attic space without forming a horizontal ceiling plane. In addition, it is possible to save labor for the construction of complicated huts, and at the same time as the upper building, heat insulation of the roof surface is ensured, so that the labor of the frame construction and the heat insulation work can be saved, and the construction period can be shortened. In addition, by inserting a composite part of channel steel and joining wood between the wall and the hut, or an assembly through member that combines the channel steel and lip channel steel in a box shape, the wall construction surface becomes a surface caused by wind, etc. The effect of constraining outward deformation can also be expected. In addition, since the tapping screw and screw nail for fixing the structural roof structure in which the heat insulating material is incorporated do not directly contact the shape steel, there is an effect that a thermal bridge cannot be formed on the roof surface and a loss of heat insulating performance can be avoided.
