Traditionally, there have been a variety of metal tile stick roofs,
In order to connect the upper and lower roof panels in a watertight manner, there are problems such as a complicated structure, troublesome construction, and increased construction costs. Since the pattern is constant, there is little change in appearance and lacks aesthetics.・[Means for solving the problems] Therefore, as a result of intensive research in order to solve the above problems, the inventor has developed the present invention by forming rising portions on both sides of the main plate in the width direction. An upper roof plate with a connecting part at the upper end of the rising part and a three-arc-shaped external bulge projecting outward from the main plate end on the underwater side, which is approximately the same as the upper roof plate. An arc-shaped inner bulge corresponding to the outer bulge is formed on the main plate on the water side of the lower roof plate having a cross-sectional shape, and a groove is provided at the periphery of the inner bulge. Equipped with
By creating a roof joint structure in which the outer bulge of the upper roof plate overlaps the inner bulge of the lower roof plate, the joint between the upper and lower roofs, which have the same cross-sectional shape, can be easily and watertightly connected. It can be constructed easily, has the appearance of a tiled roof, and solves the above-mentioned problems.

〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 1 to 8.

Reference numeral A denotes a metal upper roof plate, in which rising portions 2, 2 are bent on both sides of the main plate 1 in the width direction;
A connecting portion 3.3 is formed from the upper end of 2. Connecting part 3
In this embodiment, a substantially horizontal top portion 3a is formed inward from the upper end of the rising portion 2, a side portion 3b is bent downward from the inner end of the top portion 3a, and the side portion 3b is bent from the lower end of the side portion 3b. A folded edge 3c bent in an arc shape is integrally formed on the top portion 3a side (see FIG. 4).

Another example of the connecting portion 3 is the top portion 3a of the above example.
There is one in which only the upper end of the rising portion 2 is formed inward from the upper end (see FIG. 8).

An arcuate outer bulge 4 is integrally formed so as to protrude outward from the end of the main plate 1 on the water side to the upper roof plate (see FIG. 4). Specifically, the top side 4a is integrally formed with the main plate 1 so as to protrude outward in an arc shape from the underwater side end of the main plate 1.

The top side 4a is slightly inclined upward with respect to the main plate 1 (see FIG. 3). A side edge 4b is formed downwardly on the outer periphery of the top edge 4a. The vertical width of this side 4b becomes gradually smaller toward the lower edge of the main plate 1 (see FIG. 4).

B is a lower roof plate made of metal, and its shape is the same cross-sectional shape as the upper roof plate A. That is, rising portions 6.6 are bent on both sides in the width direction of the main plate 5, and connecting portions 7.7 are bent and formed at the upper ends of both rising portions 6.6.

The embodiment of this connecting part 7 is the same as that of the upper roof plate A,
A substantially horizontal top portion 7a is formed inward from the upper end of the rising portion 6, and a side portion 7b is bent downward from the inner end of the top portion 7a, and an arc-shaped portion extends from the lower end of the side portion 7b toward the top portion 7a. A folded cage 7C is integrally formed (see Fig. 4).

Another embodiment of the connecting portion 7 of the lower roof sheet B to the upper roof sheet is one in which the top portion 7a is formed inward from the upper end of the rising portion 6 (see FIG. 4).

Here, the concept of the upper roof sheet A and the lower roof sheet B refers to the positional relationship in which they are constructed at upper and lower positions at the joint location (see FIGS. 2 to 4).

Therefore, since the upper roof plate A and the lower N root plate B in the present invention indicate a vertical positional relationship, as shown in FIG. The temporary upper part of the adjacent building is the upper roof plate A.
, the lower one becomes the lower roof plate B (see Figures 2 and 4).

An inner bulge 8 is integrally formed on the main plate 5 on the water side of the lower roof board B so as to correspond to the outer bulge 4 (see FIG. 4). Specifically, the inner bulging portion 8 is formed in an arcuate shape inwardly from both sides of the main plate 5 in the width direction from the water-side edge of the main plate 5. It is formed in substantially the same shape as part 4.

The inner bulging portion 8 is also formed from a top side 8a and a side side 8b. The vertical width of this side 8b is such that the upper edge of the main plate 5 is approximately on the same plane as the main plate 5, and toward the center of the main plate 5,
It is formed so that it gradually becomes higher (see Figure 4).

Further, a groove 8c is formed along the arc-shaped periphery on the top side 8a of the inner bulge 8. This /JI8c may be formed continuously along the circular arc periphery (see Figure 4), or the groove 8c may be divided at the center of the inner bulge 8 (see Figure 5). ). In addition, at a small portion of the rising portion 6 on the water side of the lower roof sheet B (where the upper roof sheet A overlaps the lower roof sheet B), a connecting portion 7 is attached to the upper end thereof.
is not provided (Fig. 4).

(See 5th review).

Furthermore, a vertical groove portion 6a is formed in the rising portion 6 where the connecting portion 7 is not provided so as to protrude outward (see FIGS. 4 and 5).

In addition, the main plate 1 of the upper roof plate A and the main plate 5 of the lower roof plate B
In some cases, arcuate bulges 9 having substantially the same shape as the outer bulge 4 or the inner bulge 8 are formed at appropriate intervals in the longitudinal middle of the bulge (see Fig. 5). ). Furthermore, the surfaces of the outer bulge 4, the inner bulge 8, and the arcuate bulge 9 (the top edge 4a of the outer bulge 4, and the top edge 8a of the inner bulge 8) ) may also be shaped into a waveform (fifth).
(see figure).

Also, the upper roof plate A and the lower roof plate B are names given based on the vertical relationship in construction, and in reality, as shown in FIG. However, inner bulges 8 are often formed on the water side.

In the figure, 10 is a structural material such as a cross beam or a main building, 11 is a base material such as wood wool board 1 foam synthetic resin, rock wool, etc.
It is laid out on 0.

First, place the lower roof board B on the base material 11 (if the base material 11 is not laid on the structural material 10, on the structural material IO).
Gaii! ii and fixed with ropes etc. Next, the underwater side of the upper roof sheet A is placed on the water side of the lower roof sheet B, and the outer surface side bulge 4 is superimposed on the inner side bulge 8 of the lower roof sheet B (see Fig. 3). ). At this time, the inner bulge 8
Seal material 1 is applied to 118C and the protruding strip 6a of the rising portion 6.
2 may be inserted (see Figure 3). The upper roof plate A is also fixed onto the structural material 10 or the base material 11 using hangers or the like. By repeating these steps in sequence, the roof is constructed in the upper and lower directions.

Next, the upper roof plate A adjacent in the width direction of the roof.

The joint locations between the roof panels or between the lower roof panels B and B will be explained. In this case, the horizontally adjacent upper roof plate A,
Since the connecting points of A and lower roof panels B and B have exactly the same structure, first of all, when talking about upper roof panels A and A,
The rising portions 2.2 facing the upper roof plate Δ are brought into contact with each other, and then the cap material 13 is fitted onto the connecting portions 3, 3 at the upper ends of the rising portions 2, 2. Specifically, the cap member 13 has a crown-shaped portion 13a having a substantially gate-shaped cross section, and fitting folded edges 13b, 13b are bent inward from both ends (see FIG. 6). The camping material 13 has a top portion 3a and a side portion 3.
It is used for the connecting part 3 composed of the folded edge 3c.

That is, the top portion 3a of the upper end of the opposing rising portion 2.2,
A resilient material 14 such as foamed synthetic resin is placed on the material 3a. Then, the cap material 13 is fitted onto the connecting portions 3, 3 via the cushion material 14, and the fitted folded edge 13b is fitted into the folded edge 3C.

Further, due to the resilient force of the cushion material 14, the fitting folded edge 13b and the folded green 3C are permanently fitted (see FIG. 7).

Further, when the connecting portion 3 is composed only of the top portion 3a, a flat plate-shaped cap material 3 is used. That is, the top portion 3a of the upper end of the opposing rising portion 2゜2,
Place cap material 13 on top of 3a! ! Place this cap material 1
Both widthwise sides of 3 are folded into top parts 3a, 3a (see Fig. 8).

〔Effect of the invention〕

In the present invention, the rising portions 2.
2, and a connecting portion 3.2 is formed at the upper end of the rising portion 2.2.
3, the upper roof plate A is provided with an arc-shaped outer surface side bulge 4 projecting outward from the 1 end of the main plate on the underwater side, and the cross-sectional shape is approximately the same as that of the upper roof plate A. Lower roof board B
An arcuate inner bulge 8 corresponding to the outer bulge 4 is formed on the main plate 5 on the water side.
A groove 8C is provided on the periphery of the roof plate B, and the outer protrusion 4 of the upper roof plate A is overlapped with the inner protrusion 8 of the lower roof plate B, thereby creating a roof joint structure. Firstly, the structure is simpler than the conventional roof joint structure, and construction can be done easily and quickly. Second, the watertightness of the joints is relatively good. Thirdly, the roof using the present invention (tile rod Thatched roof m> has various effects such as giving the appearance the atmosphere of a tiled roof and making it more aesthetically pleasing.

To explain these effects in detail, in the past, the joint structure of the tile and stick roof enclosure was complex and difficult to construct.
Furthermore, although this is hardly ever adopted due to the high cost, in the present invention, a two-arc-shaped outer surface bulge is provided so as to protrude outward from the l end of the main plate on the underwater side of the upper roof plate. The upper roof plate A can be formed by simply providing a protrusion 4, an inner bulge 8 on the water side main plate 5 of the lower roof plate B, and overlapping these outer bulges 4 with the inner bulge 8. The joint part of the lower roof plate B can be scraped, and the construction is simple and can be carried out easily and quickly.

In this way, it can be constructed by a simple operation of placing the underwater side of the upper roof plate A on the water side of the lower roof plate B and superimposing the outer side bulging part 4 on the inner side bulging part 8, The outer wall can be roofed in an extremely short period of time, and advanced skills and experience are not required.

Further, the upper roof plate A and the lower roof plate B have a simple shape and can be produced in large quantities by press working or the like, so that they can be provided at extremely low prices.

Next, in the present invention, since $8c is provided in the inner bulging part 8 of the lower roof board B, this void part of /e8C prevents the capillary phenomenon, blocks the infiltration of rainwater, and prevents rainwater from entering. n (watertightness) can be made suitable. That is, when the outer side bulging part 4 is superimposed on the inner side bulging part 8 and the respective top sides 4a, 8a are brought into close contact, a gap is formed between the top sides 4a, 8a by a8c, and this gap This prevents capillary action and prevents rainwater from entering the interior, making it possible to provide a roof joint structure with extremely good watertightness.

Further, in the present invention, the outer side bulge 4 of the upper roof plate and the inner side bulge 8 of the lower roof plate B are formed in an arc shape, and the upper roof plate A and the lower roof plate B are jointed. As shown in Fig. 1, the roof in which the joint parts are constructed in the following places and the joint parts are successively formed has an arc-shaped part of the outer bulge 4 that is continuous in the horizontal and vertical directions when viewed from the top. It is possible to provide a roof that exhibits a front-groove wave pattern and has an appearance similar to a tiled roof, and is excellent in aesthetics.

Of course, this roof joint structure can be used as a sloped or vertical wall joint structure.

In addition, if the upper roof plate A and the lower roof plate B are each made relatively long, arc-shaped bulges 9 are formed on the main plate 1 and the main plate 5 at appropriate intervals, and the roof is made of these, The number of joints in the vertical direction between the upper roof plate A and the lower roof plate B can be reduced,
Construction time can be further reduced. Also, if the sealing material 12 is inserted into the groove 8C (see Fig. 3), the upper N
When constructing the joint between the root board A and the lower roof board B, the sealing material 12 can be reliably superposed without shifting its position, and the sealing material 12 has the advantage of making the joint location even better watertight. .
