Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a roof structure for a unit building. More specifically, the present invention relates to a roof structure of a unit-type building in which a plurality of roof panels are combined on a building frame composed of building units to form a pitched roof.

[0002]

BACKGROUND ART Conventionally, in the case of constructing a pitched roof in a unit type building, a roof unit is formed in advance by factory-installing a roof panel to a base frame through a bundle or panel brackets to form a roof unit. The unit is transported to the construction site together with the building unit, the building unit is placed there to build the building skeleton, and then the roof unit is installed on it to form the roof. A roof panel framing method is known in which a roof, a beam, a mother house, and the like are assembled to form a shed, and a wooden roof panel is assembled to the shed to construct a roof.

[0003]

However, in the former roof unit system, since the roof panel is attached to the base frame in a slanted shape via the bundle and panel brackets, the transport efficiency is poor and the cost is increased. It was a factor. Moreover, since the roof panel is supported via a bundle for each roof unit, when the roof unit is installed on the building frame, the bundles of the roof units are arranged adjacent to each other at the joint of the roof units. In addition, as a result of the base frame and the upper beam of the building unit on the top floor overlapping, it is not economical from a material standpoint. Further, in the latter roof panel frame system, since a hut has to be formed at the construction site, there is a lot of work at the construction site, which is a factor that the construction period and cost cannot be reduced. Moreover, since these works are works at high places (work on the building frame), they are dangerous and inefficient.

An object of the present invention is to provide a roof structure for a unit-type building which solves the above-mentioned conventional problems, can be easily and economically constructed, and can improve the strength against external force. is there.

[0005]

The roof structure of a unit type building according to the present invention has a structure in which a plurality of roof panels each having a panel frame and a roof material attached thereto are combined to form a pitched roof. A roof structure of a unit building constructed, wherein a joint portion between the roof panels is located on a beam of the building unit.

Further, the roof structure of the unit type building of the present invention is a unit type structure in which a plurality of roof panels constructed by attaching a roofing material to a panel frame are combined on a building frame composed of building units to form a pitched roof. A roof structure of a building, wherein a joint between the roof panels is located on an upper beam or an intermediate beam provided between the upper beams of the building unit, and a bundle is erected on the upper beam or the intermediate beam. The upper end of this bundle supports a panel frame at the joint between the roof panels, and the panel frame and the bundle and the upper beam or an intermediate beam provided between the upper beams form a truss.

Here, it is preferable that the upper end of the bundle has a receiving plate for supporting the panel frames at the joint portion of at least two roof panels adjacent to each other. Furthermore, it is preferable that the lower end has a connecting plate that connects between adjacent building units, for example, between adjacent upper ends of columns. Further, it is preferable that the truss constitutes two vertical construction surfaces that are orthogonal to each other.

[0008]

According to the roof structure of the unit type building of the present invention,
Since the joints between the roof panels are located on the beams of the building units, if a bundle is erected on the beams of the building unit, the joints between adjacent roof panels can be supported at the top of the bundle. It can be done economically without duplication of materials. Moreover, in terms of construction, in the factory, the roof material was attached to the panel frame in advance to manufacture roof panels, which were then transported to the construction site, whereupon they were bundled on the beams of the building units that compose the building frame. Since it suffices to stand upright and support the joint portion between the adjacent roof panels at the upper end of this bundle, the construction can be performed easily.

Further, the joint portion between the roof panels is positioned on the upper beam or the intermediate beam provided between the upper beams of the building unit, and a bundle is erected on the upper beam or the intermediate beam, and at the upper end of this bundle. Since the panel frame at the joint portion between the adjacent roof panels is supported and the truss is constituted by this panel frame, the bundle and the upper beam or the intermediate beam, the strength against external force can be improved.

At least two adjacent to the upper end of the bundle.
If the structure has the receiving plate that supports the panel frames in the joint portion of the two roof panels, at least two roof panels can be supported in a slanted manner by one bundle and are adjacent to each other via the bundle. Two roof panels can be joined together. Further, if the lower end of the bundle has a connecting plate for connecting adjacent building units, if the connecting plates connect the adjacent building units, the bundle can be erected between them.
In addition, if the trusses are configured to form two vertical structure surfaces that are orthogonal to each other, the strength can be improved against external forces from all directions including two directions that are orthogonal to each other.

Since the receiving plates 15B for supporting the upper ends of the roof panels 25, 26 are provided respectively, the adjacent roof panels 21, 22, 2
The roof panels 2 adjacent to each other through the bundle 11 can support the three members in a slanted manner by one bundle 11.
1, 22, 23 can be integrally joined. Further, since the lower end of the bundle 11 is provided with the connecting plate 14A for connecting between the upper ends of the four columns 4 of the uppermost building unit 2, the uppermost building unit 2 can be connected by the connecting plate 14A. In the meantime, the bundle 11 can be built.

In the construction, the roof members 27, 2 are attached to the panel frames 24, 25, 26 in advance at the factory.
8 and 29 are attached to manufacture roof panels 21, 22, and 23, and it is only necessary to transport the roof panels 21, 22, and 13 together with the bundles 11, 12, and 13 to the construction site. Therefore, the transportation efficiency can be improved as compared with the conventional roof unit. . Moreover, at the construction site, the bundles 11, 12, 13 are erected on the building frame 3 formed by the building units 1, 2, and the bundles 11, 1
Roof panels 21, 22, 23 adjoining at the upper end of 2, 13
Since it suffices to support the joints between them, the material can be economical without duplication, and the construction can be performed easily.

Although the present invention has been described above with reference to the preferred embodiments, the present invention is not limited to these embodiments, and modifications can be made without departing from the gist of the present invention. For example, in the above embodiment, the bundle 11 is erected right above the four pillars 4 where the building unit 2 is assembled, but it may be placed on the upper beam 6B of the building unit 2. The bundles 12 and 13 may also be erected on the intermediate beam 7 instead of on the upper beam 6A of the building unit 2. In short, the upper beams 6A, 6B or the intermediate beams 7 of the building unit 2, the panel frame 24,
25, 26 inclined panel frames 24A, 25A, 2
As long as the truss can be configured to include 6A and the bundles 11, 12, and 13, the arrangement positions of the bundles 11, 12 and 13 and the lower end support positions of the inclined panel frames 24A, 25A and 26A may be any positions.

In the above embodiment, the bundle 11 and the bundle 1
If the brace is inserted diagonally between the bundle 11 and the bundle 11 between the bundle 2 and the bundle 2, the truss can also be formed by this, so that the strength can be further increased. Further, in the above embodiment, the dormitory roof has been described, but not limited to this,
It can also be applied to other pitched roofs such as gable roofs.

[0025]
