Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof bundle supporting structure for a unit type building.

[0002]

BACKGROUND ART A unit-type building is formed by including a foundation part constructed on site, a building body arranged on the foundation part, and a roof part arranged on the building body. There is. Of these, the building body consists of a combination of multiple building units, and this building unit includes pillars erected at the four corners, and upper and lower beams spanning between the upper ends and lower ends of these pillars. Is formed by. In addition, if necessary, the upper part of the building unit may be provided with four 4 beams corresponding to the four upper beams.
A shed panel in which the frame members of a book are combined in a square shape is arranged. Further, the roof portion is provided with a roof panel in which a roof material is previously mounted on a frame in a factory, and a roof bundle for supporting and fixing the roof panel to form a roof slope, and the roof bundle is A plurality of upright beams are erected in accordance with the allocation of the roof panels with the upper surfaces of the two upper beams forming the adjacent building units or the upper surface of the frame material forming the shed panel as a supporting surface.

[0003]

However, the roof bundle which is erected on the outer peripheral portion forming the outer wall of the building body is
Only the upper surface of one upper beam or one frame member can be used as the supporting surface, and in such a roof bundle supporting structure, due to an external force applied by the typhoon or earthquake transmitted through the roof bundle. In order to prevent deformation and lateral buckling of the frame material that constitutes the upper beam or hut panel, and to have a structure with sufficient yield strength,
For example, changing the material of the upper beam or the frame material that becomes the supporting surface of the roof bundle, increasing the material thickness of the upper beam or the frame material, changing the cross-sectional shape of the upper beam or the frame material, and many It is necessary to take measures such as attaching stiffeners to reinforce the upper beam or the frame material, and when manufacturing building units or shed panels in factories, increase costs and management complexity due to member changes, and complicate assembly process. There was a problem such as.

An object of the present invention is to solve the above-mentioned conventional problems and to provide a roof bundle supporting structure for a unit type building having necessary and sufficient strength without changing the material specifications of the building unit or the shed panel. Is provided.

[0005]

According to the present invention, there are formed pillars which are erected at four corners, and four upper beams and lower beams which are bridged between upper ends and lower ends of these pillars. In a roof bundle supporting structure of a unit type building in which a roof bundle for supporting a roof panel is erected on a built building unit, the roof bundle includes one of the four upper beams, and It is characterized in that it is erected in parallel with the upper beam of the book and erected over a reinforcing beam which is a constituent element of the building unit.

In addition, the roof bundle has four columns which are erected at the four corners and bridged between the upper ends and the lower ends of these columns.
A shed panel in which four frame members corresponding to the four upper beams of a building unit including upper and lower beams are combined in a quadrangle shape on the building unit. It may be erected upright over one of the four frame members of the panel and a reinforcing beam that spans the frame member in parallel and is a constituent element of the shed panel. .

In addition, a short horizontal furring bridging between the two roof bundles may be attached to the outdoor side surface of the roof bundle in order to fix the outer wall material. A long horizontal furring spanning the roof bundle may be attached.

In the roof bundle, the bottom of the roof bundle main body may be erected over the upper beam and the reinforcing beam or the frame member and the reinforcing beam, and the roof bundle main body may be provided at the bottom. The roof bundle may include a base plate having an area larger than the bottom area of the base plate, and the base plate may be erected over the upper beam and the reinforcing beam or the frame member and the reinforcing beam.

[0009]

According to the present invention, the roof bundle is erected by straddling the frame beams and the reinforcing beams forming the upper beam or the shed panel forming the building unit. The external force acting on the roof panel, which is a constituent element of the roof portion due to a typhoon or an earthquake transmitted via the above, must be distributed to and carried by the upper beam and the reinforcing beam or the frame member and the reinforcing beam. Therefore, it is possible to obtain the supporting structure for the roof bundle of the unit type building having necessary and sufficient strength without changing the material specifications of the building unit or the shed panel against external force acting on these roof panels.

Further, by mounting the horizontal furring strips for fixing the outer wall material over a plurality of roof bundles, it becomes unnecessary to bridge a plurality of short horizontal furring strips between the two roof bundles. Administrative effort can be reduced.

Furthermore, since the roof bundle is provided with the base plate having a larger bottom area than the bottom area of the roof bundle main body, the roof bundle can be surely straddled by the upper beam and the reinforcing beam. The roof bundle can be easily erected on site.
