Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof unit which constitutes a roof portion of a unit building, and is particularly applied to a roof portion such as a hipped roof in which a plurality of roof surfaces are complexly connected and combined. A preferred roof unit.

[0002]

2. Description of the Related Art Unit buildings are widely used as one method for increasing the industrial production rate of buildings. A unit building is a building in which one building is divided into several units in advance and produced in a factory, and these are constructed / assembled at a construction site. As a unit that constitutes a unit building, there are a room unit that constitutes each room portion such as a living room, a dining room, and a bedroom, and a roof unit that constitutes a roof portion of the building. When assembling and constructing a unit building, multiple room units produced at the factory are connected to each other and installed on the foundation of the construction site.In addition, multiple roof units are installed on top of each installed room unit. It will be installed and connected to the.

The roof unit comprises a roof panel having a roof surface, and support frames which are arranged at opposite ends of the roof panel to face each other and support the roof panel. The roof panel is formed as a roof structure by assembling a rectangular roof frame using a plurality of frame members and further attaching a roof surface material to the surface of the assembled roof frame with nails or the like. Further, the support frame is formed by assembling into a structure capable of supporting the roof panel using a plurality of frame members.

By the way, in the above-mentioned conventional supporting frame, for example, as is clear from the description of Japanese Patent Laid-Open No. 62-6041, the upper contour is defined along the flow (inclination) of the corresponding roof panel. It was For example, in the case of a roof unit that constitutes a gable roof, the support frame of the roof unit that constitutes the ridge side is arranged along the roof panels of both flows,
The upper part was formed in a pentagonal shape with a mountain shape, and the support frame of the eaves side roof unit was formed in a right-angled triangular shape with an oblique side in the upper part so as to follow the one-way roof panel. Generally, the conventional support frame is formed to have the shape of the entire side surface of the roof unit. In the case of a roof unit that constitutes a gable roof, one type of support frame is prepared for roof units of the same shape (same shape and same size) because the opposite side surfaces have the same shape and dimension. If there are 10 different types of roof units, it is sufficient to prepare 10 different types of support frames.

[0005]

However, according to the structure of the conventional roof unit described above, the roof panels 3 to 5 and 6 like the roof units 1 and 2 for the hipped roof shown in FIGS. 7 and 8. In the case of roof units (hereinafter also referred to as complex-shaped roof units) 1, 2 with complicated installation of 7 and 7 (roof surface flow) and side heights differing on both sides, 2 types per roof unit The supporting frames 8, 9, 10 and 11 are required.

On the other hand, as a tendency in recent years, a lot of building units having a roof pattern with a taste have come to be reflected in consideration of the diversification of the taste of the building owner, and as a result, many roof units having a complicated shape have become popular. Being produced. This type of roof unit is produced after an order is received. In this case, roof panels 3 to 5, 6, 7 and support panels are provided as shown in the same figure depending on the site conditions and the request of the building owner. Frames 8, 9,
It is usual to change the shape and size of 10 and 11 to newly manufacture. Therefore, each time a new roof unit of this type is produced, the number of types of support frames increases remarkably. For example, in the case of producing 10 types of roof units having complicated shapes different from each other, the number of support frames is increased accordingly. Twenty types of frames had to be prepared, which hindered production costs and management. It has also been pointed out that the conventional structure in which only both end portions of the roof panel are supported by the support frames is structurally unstable for a roof panel having a complicated shape.

The present invention has been made in view of the above circumstances, and provides a roof unit capable of reducing the number of specific constituent members (supporting frames) and strengthening the structure as a whole. The purpose is to do.

[0008]

In order to solve the above problems, a roof unit according to claim 1 joins at least one roof panel having a roof surface and a support structure for supporting the roof panel. In the roof unit formed as described above, the support structure includes two flat side support frames disposed on opposite sides of each other and at least one flat surface provided between the side support frames. It is characterized in that it is a three-dimensional support structure consisting of a frame-shaped erection support frame.

According to a second aspect of the present invention, there is provided a roof unit in which the erection support frame is provided with a lower cross member for erection between the two side support frames and at least one roof panel in a predetermined inclined state. The truss structure is characterized by including a diagonal member for supporting and fixing the diagonal member and a vertical member for supporting one end of the diagonal member.

Furthermore, the roof unit according to claim 3 has at least two roof panels each having roof surfaces that flow perpendicularly to each other, and the two side support frames have the same shape and the same size. It is characterized by being formed in.

[0011]

According to the structure of the present invention, since the roof panel is supported by the three-dimensional support structure instead of the conventional planar support structure, the proof stress against snow load and wind load is enhanced. It is possible to obtain a roof unit that is structurally more stable. Therefore, the roof unit of the present invention is suitable for application to a roof portion such as a hipped roof in which a plurality of roof surfaces are complexly connected and combined.

Further, the roof support panel can be supported in a predetermined inclined state by using the erection support frame according to claim 2.
By supporting a roof panel having a flow in the lateral direction of various roof units having a complicated shape, it becomes possible to form various roof units by using two side support frames having the same shape. As a result, when there are 10 types of roof units having a complicated shape, a total of 11 types of support frames including 10 types of side support frames and a single type of universal erection support frame may be prepared. Therefore, it is possible to reduce the number of the specific constituent members (support frame) as a whole. Therefore, the work cost is significantly reduced.

In contrast to the use of one erection support frame 37, 37, in the roof unit 48, only one erection support frame is used because the roof panel 59 is smaller than the corresponding roof panel 26. Moreover, since there is no corresponding roof panel 27, it is sufficient to support only one erection supporting frame. In addition,
The procedure for assembling the roof unit 48 is as follows.
Since it is almost the same as that of No. 1, its explanation is omitted.

According to the structure of the roof unit 15 (48), the roof panels 25, 26, 27 having a complicated shape as a whole are formed.
Since (58,59) is supported by the three-dimensional support frame 28 (60) having a three-dimensional truss structure, the proof stress against snow load and wind load is strengthened, and a structurally more stable roof unit is obtained. You can Further, in forming the various roof units 15 and 48 having a complicated shape, the triangular support frames 37 having the same shape are used to support the roof panels having a flow in the lateral direction of each roof unit. This allows each roof unit to be formed using two side support frames of the same shape. As a result, when there are 10 types of roof units having a complicated shape, a total of 11 types of support frames including 10 types of side support frames and a single type of universal erection support frame may be prepared. Therefore, it is possible to reduce the number of deformed points of the support frame as a whole. Therefore, the work cost is significantly reduced.
