DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field 1] The present invention is directed to the top and bottom seven roof panels that are connected vertically and horizontally to form a roof surface. 11 rainwater from the knot! It can be firmly fixed to the root base material without penetrating into the back side of the roots, and snow accumulated on the roof surface can easily fall off naturally.
It is placed between roof panels made of gold i, which is also aesthetically pleasing. [Prior Art] Conventionally, @I-roots made of metal plates such as copper plates have been manufactured with various features such as beauty of appearance and ease of construction. In many cases, the roof surface is constructed by connecting a large number of rectangular root plates from the pot vertically and horizontally with the longitudinal direction horizontal. The conventional roof panels used in this way and their N-frame conditions will be explained below with reference to the drawings. FIG. 5 is a perspective view taken from slightly above, showing an example of a conventional II roof panel; FIG. 6 is a perspective view of the same roof panel shown in FIG. 5, showing a state where the roof panels are connected vertically and horizontally; The figure is Y- in Figure 6.
FIG. 3 is an enlarged explanatory end view along Y-line. The conventional roof board 10 shown in FIG.
! 1115, a lower side folded part 4 and a left side folded part 6 folded back to the 1 side. In this conventional roof board 10L, the insertion engagement state of each part is good when connecting the upper and lower left and right sides, and the upper and lower connecting parts 9
In order to prevent rainwater f from entering and leaking due to the capillary phenomenon after being crimped, the upper side folded portion 3 has a raised aIS3d and a lower side engagement portion 3e continuous thereto, as shown in FIG. The lower side folded portion 4 usually consists of a rising portion 4a and a lower side engaging portion 4b continuous therewith. To make four sheets of such conventional roof shingles 10 vertically and horizontally, as shown in FIG. In the case of the illustrated example, the left-side folded portion 6 is inserted and engaged with the lower surface of the right-side folded portion 5 (by pushing it from below) to form the left-right connected M portion 8. and 1
While the folded pieces 7a at the lower end of the hanger 7 are inserted and engaged with the lower surface side of the upper side folded part 3 at intervals of 5 to 30 CI, the upper part of the hanger 7 is nailed to the rafters of the roof base material and the roof board 10 is attached. Fix it. Repeat this to create the lower m root plate row. Next, the lower side folded portion 4 of the upper roof sheet 10 is attached to the lower roof sheet 10.
One person engages with the lower surface side of the upper folded portion 3 to form the upper and lower connecting portions 9. In this case, left and right connection 1!1ls8
And upper and lower Ml! In order to avoid overlapping with II$9 and make it too thick and to improve the aesthetic appearance of the entire m root, the longitudinal center of the upper am root plate 0 is connected to the left and right of the lower ff1ll plate 10. It is normal to place it at position lll8. The upper side is also fixed with the hanger 7 in the same way as the lower side. The roof is constructed in this way. Problem to be Solved by the Invention 1 The upper and lower connecting parts 9 of the roof surface made up of such conventional roof panels 10 are of M4 construction as shown in FIG. 7, and the rising parts 3d and 4a Even if the opening is not very high, a narrow gap is created in the upper and lower connecting parts 9, and the rainwater W blown up by the wind moves in the direction of the arrow and turns into layer fog due to the capillary W phenomenon. There was a problem that it was easy to migrate and leak. Furthermore, in order to minimize such rain leakage, the conventional roof shingles 10 are often folded back on the upper side l'! Although the length L' of IS3 was increased, the effect of preventing rain leakage11 was reduced, and on the other hand, the hanger 7 had to be changed, so the fixing state of mi root plate 0 to the roof base material was changed. There was a problem with the roof panels being prone to flapping on windy days. Also, the bottom side is folded i! The height of the rising part 4a of 1ls4 is low and it is easy to be stepped on and flattened (which makes it unsightly), and there is also the rIA problem that it is difficult for snow to fall naturally when it snows. [11 To solve the Alffi point Means 1 The present invention includes:
This was completed as a result of studies aimed at providing a means to solve the problems of conventional roof panels as described above. That is, in the present invention, the upper side,
In a roof board that has folded portions on the lower side, right side, and left side, and is bent four times vertically and horizontally by insertion and engagement of the opposing folded portions to form a roof surface, the lower side folded A11. The extended portion of the lower side of the roof sheet body is bent toward the ridge surface at the first bending line to form a high rising part, and then bent toward the upper side along the roof surface at the second bending line. and an upper side engaging part is provided, and the upper side folded part is formed by folding the upper side extension part of the roof plate body to the front side at the first folding line and then folding back to the back side at the second folding line. A hanger engaging part is provided in which the folded piece at the lower end of the hanger is inserted and engaged, and is folded back to the front side at the third bending line so that it is located on the lower side of the second bending line and on the roof surface. It extends in the direction away from the roof to a height corresponding to the rising part of the lower folded part, then forms a rising part towards the roof at the fourth bending line, and then further bends it towards the upper side at the fifth bending line. The present invention relates to a roof plate characterized in that a lower side engaging portion is provided between the roof plate body and the lower side folded portion of the upper roof plate to be inserted and engaged. Hereinafter, the present invention will be explained with reference to the drawings. FIG. 1 is a perspective view showing one embodiment of the roof board according to the present invention, seen from slightly diagonally above; FIG. 2 is the same perspective view showing the roof board of FIG. 1 connected vertically and horizontally; FIG. 3 is an enlarged explanatory end view along the line X--X in FIG. 2, and FIG. 4 is a partial perspective view showing the rising portion 1g of the lower folded portion. As shown in FIG. 1, the roof panel 1 according to the present invention has a rectangular roof panel body 2 with upper folded portions 3 on the four peripheries. Lower side folded part 4.
The right side folded part 5 and the left side folded part 6 are respectively formed, which is the same as the conventional roof board 10, but the feature is that the height of the rising part 4a of the lower side folded part 4 is increased and the upper side folded part 3 is formed. In addition to having a specific two-tiered structure, a rising portion 3b having a height corresponding to the rising portion 4a of the lower side folded portion 4 is provided at a position close to the rising portion 4a in the connected state. That is, as shown in FIG. 3, the lower side folded portion 3 is formed after the lower side extended portion of the roof plate body 2 is bent toward the roof surface along the first bending line A1 to form a high rising portion 4a. It is bent toward the upper side along the roof surface at the second bending line A2, and an upper side engaging portion 4b is provided. It is preferable that the edge of the upper side engaging part 4b is formed into a folded part aba which is further folded back to the front side as shown in FIG. It is preferable to provide a protruding convex rib 4aa in the height direction. Although the height of the rising portion 4a varies depending on the size of the roof board 1, it is preferably about 1.5 to 3 inches. As shown in Fig. 3, the upper side folded portion 3 is formed by folding the upper side extension of the roof plate body 2 to the front side at the first bending line B1, then to the lower side, and then folding back to the back side at the second bending line B2. is provided with a hanger engaging portion 3a, which is further folded back to the front side at the third bending line B3 and extends toward the lower side and away from the roof surface from the second bending line B2, The height corresponding to the rising part 4a of the lower side folded part 4, that is, the fourth fold line F1 after extending to the vicinity of the first folding line A1 of the lower side folded part 4 in the connected state described later.
4 toward the roof, forming a rising portion 3b having approximately the same height as the rising portion 4a of the lower side folded portion 4, and then further bending toward the upper side at the fifth bending line 85 to form the lower side. The engaging portion 3CtfiQ is cut out. In such a configuration, the fourth bending line B4 is located on the lower side of the second bending line B2, and the second bending line 82 is located between the third bending line 83 and the fourth bending line. It is above the plane reaching line B4. Therefore, this upper folded part 3 has a double structure, with a hanging part engaging part 3a folded back from the second folding line B2 and a fourth folding part 3a folded back from the third folding line B3. As shown in FIG. 3, a space S is formed between the bending line B4 and the surface extending to the bending line B4. The cross-sectional shape of the upper side folded portion 3 shown in FIG. 3 is merely an example, and various other shapes can be taken. For example, the extension of the roof body 2 is the first bend line]; It may also be folded back to the front side through the -hito rising portion. Furthermore, in order to make the space S as large as possible, it is preferable to extend from the third bending line B3 through a portion parallel to the roof surface and then away from the roof surface. As described above, the upper side folded portion 3 is formed. At one end of the upper side folded part 3 in the lateral direction, in order to avoid excessive thickness due to overlapping of the respective parts at the left and right connecting parts 8, the right side folded part 5 of the upper side folded part 3 is attached as shown in FIG. Alternatively, it is preferable to cut out the portion after the second bending line B2 of the portion that overlaps with the left-side folded portion 6. In the above embodiment, a simple structure consisting of one folded piece is shown as the right side folded part 5 and the left side folded part 6, but the present invention is not limited to such a structure. It may be devised to prevent rain from leaking from the four connecting portions 8 of Showa Go-5 (as described in No. I104). Further, the respective folding sides of the right side folded portion 5 and the left side folded portion 6 may be opposite to those in the above embodiment. [Construction Method] In the method of constructing a roof using the roof shingle 1 according to the present invention, when fixing the roof shingle 1 to the roof base material with the hangers 7, the folded pieces 7a of the hangers 7 are attached to the upper side as shown in FIG. When inserting and engaging the lower surface side of the hanging hook engaging part 3a of the folded part 3, and when engaging the lower side folded part 4 of the upper side board 1 with the upper side folded part 3 of the lower roof board 1, This can be carried out in the same manner as when using the conventional roof board 10, except for inserting and engaging the former upper side engaging part 4b into the lower surface side of the latter lower side engaging part 3C. (Operations and Effects 1) As described above, the roof board 1 according to the present invention not only increases the height of the rising portion 4a of the lower side folded portion 4, but also has the upper side folded portion 3 of a specific two-tiered structure. By providing a rising portion 3b having a height corresponding to the rising portion 4a of the lower side folded portion 4 in the connected state, the roof surface constructed from the rising portion 3b has the same height as that of the upper roof sheet 1 as shown in FIG. On the inside of the lower end of the roof plate main body 2, there is a surface extending from the third bending line B3 to the fourth bending line B4 and the hanging hook engaging part 3a of the upper side folded part 3 of the lower roof plate 1. , a space S with a relatively large gap is formed.Therefore, rainwater W blown up by the wind is absorbed into the roof plate body 2 of the lower roof plate 1 and the lower side engaging portion 3C of the upper side folded portion 3.
and the upper side engagement 8IS of the lower side folded part 4 of the upper roof plate 1
Even if water infiltrates into the interior in the direction of the arrow through the gap formed by 4b in the direction of the arrow due to capillary action, once it reaches the space S, the capillary current will disappear due to the large gap and there will be no further infiltration into the attic. Water leakage is prevented. Furthermore, since the length of the hanging hook engaging part 3a of the upper side folded part 3 does not prevent rainwater W from entering, it may be short. It is possible to shorten the length up to 7.
By shortening the length of the roof plate 1, the roof board 1 can be firmly fixed to the roof base material. Furthermore, by increasing the height of the rising portion 4a of the lower side folded portion 4, snow accumulated on the roof surface during snowfall can easily fall off naturally. The reason for this is not clear, but it is thought that the height difference between the first roof sheets divides the roof surface's resistance to the snow's actions.Also,
The high height of the rising portion 4a has the effect of improving the aesthetic appearance of the roof. By making the height of the rising portion 3b of the upper side folded portion 3 correspond to the height of the rising portion 4a of the lower side folded portion 4, as shown in FIG. It will support the weight and will not flatten even if stepped on. In this case, the lower side engaging portion 3C of the upper side folded portion 3 not only has an engaging function but also has the function of preventing the rising portion 3b from deforming due to heavy pressure. Furthermore, when the raised portion 4a of the lower side folded portion 4 is formed with a convex rib 4aa, its anti-load effect is further strengthened.
