Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a roof panel installed on a shed for building a roof, and particularly to a roof unit suitable for use in a roof having a complicated roof shape. Regarding the method.

[Conventional technology]

Since a roof can be constructed with a relatively simple roof structure, a construction method using a roof panel as a foundation of the roof structure is widely used.

FIG. 5 shows a two-story building with roof panels installed on the shed. The roof type of the illustrated building is a gable roof, and rectangular panels are used as roof panels. A plurality of roof panels 10 are installed in both directions along the slope of the roof centering on the purlin, and constitute the foundation of the roof surface.

6 (A) and 6 (B) show an example of the structure of the roof panel 10, FIG. 6 (A) shows the front side, and FIG. 6 (B) shows the back side. 12 is a frame,
A plate member 14 is stretched on one side surface of the lattice-shaped frame body 12 to form a panel. The plate member 14 is not limited to one side surface, and may be stretched to both side surfaces.

The size of each roof panel 10 is standardized into a plurality of types, and various sizes are used according to the size of the roof.

By using such a roof panel, it is possible to construct a roof with a rooftop structure that is relatively easily configured using a roofing panel or the like. That is, it suffices to provide a roof support structure in a portion necessary to install the roof panel 10,
There is no need to construct a roof truss using many beams and rafters.

[Problems to be Solved by the Invention]

However, in the case of a roof panel standardized and manufactured like the above conventional roof panel, in the case of a roof having a relatively simple shape such as the gable roof shown in FIG. However, it is not possible to easily deal with a roof having a complicated outer shape. In other words, in the case of a roof with a shape in which multiple roofs intersect and a so-called geese part exists, there is no roof panel of a size and shape that fits the special roof, so an existing panel is used immediately. Can not do it.

Therefore, there is no choice but to handle the situation by appropriately arranging the shape and size of the existing roof panel by the site workers, or by constructing the roof support structure and the roof material on site as in the conventional construction method. However, such roof panel modification work and construction on the site not only require skill but also prolong construction work time, which means that the conventional standardized roof panel alone has a relatively complicated shape. However, there was a problem that the roof could not be constructed in panel form.

[Object of the Invention]

The present invention has been made to solve the above problems, and an object of the present invention is to provide a roof panel having a size and a shape suitable for a roof having any complicated outer shape. Easy to configure,
It is to provide a method of forming a roof unit that can be easily attached.

[Means for solving the problem]

In order to achieve the above object, the present invention provides a plane shape setting step of creating a plane projection shape drawing of a roof on which a roof panel is to be installed, and a predetermined plane projection shape of the roof shown in this step. Corresponding to each subdivided panel shape, the plane division process of subdividing into two or more types of panel shapes, and the roof panel actually used based on the actual roof slope and roof size. A panel original size setting step of calculating the original size, a roof panel creating step of manufacturing a roof panel to be installed on the roof based on the panel original size set in this step, and a combination of the roof panel with other roof members And a connecting member attaching step of attaching a connecting member interposed between the roof panel and the other roof member so as to form a ridge or a valley. The features.

[Action]

According to the present invention, first, the outer shape of the roof on which the roof panel is installed and the slope change line of the roof surface are represented by a plan view.
Then, this is subdivided into a predetermined panel shape on the drawing. This panel shape is a plane projection shape of a roof panel that is actually used. That is, the roof panel shape used on the drawing is set.

Here, in order to calculate the actual size of the roof panel actually used from the small-divided panel shape, it can be easily calculated by considering the roof slope, that is, the roof surface inclination angle.

By doing this, if the above-mentioned subdivision is performed in the shape of the roof panel that can be actually manufactured, the slope of the roof is standardized to some extent, so that it is possible to adapt the slope to several types of sizes. By forming the panels in advance, it is possible to prepare a roof panel that fits the roof extremely quickly.

Therefore, since the roof panel forming method does not care about the shape of the roof, the roof panel can be used even for a roof having a complicated shape. Further, the required roof panel can be accurately formed in the panel manufacturing stage for each roof to be constructed, and the actual roof panel installation work becomes extremely simple and the work efficiency is improved.

Moreover, since the joining member having a shape capable of forming a ridge or a valley is previously attached to the joining side of the roof panel with the other roof member, the joining work of the roof panel is simplified.

〔Example〕

Preferred embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 (A), (B), (C), and (D) show examples of panel shapes for subdividing the planar shape of the roof. In this embodiment, four types of panel shapes are used,
The figure (A) is a rectangular panel 20a, and the figure (B) is a triangular panel 20a.
2B and FIG. 2C show a parallelogram panel 20c, and FIG. 3D shows an inverted triangular panel 20d.

FIGS. 2 (A) and (B) show an example of a planar shape of a roof having a relatively complicated shape. Each of them has a shape in which a plurality of roofs are crossed, and portions of geese 22a to 22d are formed. Conventionally, it is difficult to install the roof panel at the intersection of the roof surfaces having different slopes.

First, in the plane shape setting step, which is the first step of the present invention, the out-of-plane shape of the roof and the change line (ridgeline) of the roof surface slope are shown on the drawing based on the design drawing or the like. That is, the diagram represented by the thick line in FIG. 2 is created.

Next, in the plane dividing step, the plane shape of the roof shown in FIG. 2 is divided into small pieces by the arrangement and combination of the panels having the basic shape, that is, the panels 20a to 20d shown in FIG. In this subdivision, the laying efficiency of panels and the roof strength are taken into consideration. This small division is shown by a thin line in FIG. As can be seen from the figure, the above-mentioned four types of panel shapes are wholly divided.

Thus, if the subdivided panel 20 is constructed with the actual size of the roof panel 10, it is possible to obtain all the roof panels 10 necessary for constructing the roof as illustrated.
Therefore, the panel original size calculation step is performed as the third step. This calculation is performed by calculating the original size of the roof panel 10 in the direction in which there is no slope from the actual size of the roof, and calculating the actual size in the direction of inclination from the actual size of the roof and the slope of the roof surface.

In this way, when the shape of the roof panel 10 to be used is specified and the original size is calculated, the roof panel manufacturing step is performed as the final step of forming the roof panel. This process is based on the calculated actual size of the roof panel and the actual roof panel 10
Is the process of creating
Roof panel 10 required for the roof configuration shown in (B)
Are all prepared.

FIGS. 3A and 3B are views showing how to join the roof panel 10 at the corner ridge 30 and the valley corner 32 shown in FIG. FIG. (A) shows a case of a corner ridge 30, and a joining member 34 is attached to the outer surface of the frame body 12 at the joining side end portion of each roof panel 10, and by closely joining this portion, The two roof panels 10 are joined while maintaining a predetermined angle. That is, the slope of the roof surface is formed.

Next, although FIG. (B) shows the case of the valley corner 32, the coupling member 36 is provided on the frame body 12 at the joining side end of the roof panel 10 as in the case of FIG. However, the shape is different from that of the coupling member 34, and the roof panel 10 is joined so as to form a valley on the front surface side 10a in a state of being closely joined. By thus joining the corners via the joining members 34 and 36, the joining property between the panels is improved, and the joining work is facilitated by using nails or the like.

It should be noted that FIG. 4 shows a planar shape and a small division state of a roof having a relatively uncomplicated shape. In the gable roof of Figure (A), only rectangular panels are used. And
A rectangular panel and a triangular panel will be used in the parquet roof of FIG. Therefore, it is possible to construct a roof without the formation of roof panels by the method according to the invention (especially for gable roofs).
However, the use of the present invention facilitates the formation of roof panels. That is, the present invention can be preferably used for a roof having a complicated shape, but the present invention is not limited to this, and can be effectively used even for a simple roof shape.

〔The invention's effect〕

As described above, according to the present invention, it is possible to easily manufacture a roof panel that exactly fits the roof regardless of the shape of the roof. Particularly in the case of a roof having a complicated outer shape, it is possible to form a roof using a roof panel, which has been difficult, and the efficiency of construction work is improved.
