FIG. 9 is a partial explanatory diagram for explaining a first procedure for constructing a dormitory roof using a corner decoration for roof, and FIG. 10 is a partial explanation for explaining the second procedure. FIG.
[0007]
Reference numeral 10 denotes a roof corner ornament body made of a thin metal plate. In the unfolded state as shown in FIG. A projecting portion 14 having a lower projecting portion 13 having a top portion having a required angle on the extension line of the vertical portion 12 is formed on the extension line of the vertical portion 12, and a pair of peaks is formed between the pair of vertical portions 12. A shape projecting portion 15 is continuously formed, and a corner decoration portion 17 is integrally formed between the lower projecting portions 13 so as to integrally have a locking collar portion 16 on the periphery.
Two first locking piece portions 18 and second locking piece portions 19 are formed integrally with the locking collar portion 16 of the corner decoration portion 17.
1, 20, 20, 21, 22, 22, 22, 23, and 23 are virtual folding lines, respectively.
Needless to say, the shape, quantity and position of the first locking piece 18 and the second locking piece 19 can be changed as needed.
[0008]
In forming the roof corner ornament 24 of the present invention using the roof corner ornament body 10 made of such a thin metal plate, first, as shown in FIGS. The first virtual folding lines 20 and 20 shown in FIG. 1 on the line connecting the portion 12 and the top portion 13a of the downward projecting portion 13 are bent to the surface side, respectively, and the top portions 15a of the pair of upper mountain-shaped projecting portions 15 are bent. The second virtual folding lines 21 and 21 shown in FIG. 1 on the extended line are bent to the back side to form corner decoration overlapping portions 25 and 25, respectively.
[0009]
Next, as shown in FIGS. 4 to 5, the locking collar portion 16 of the corner decoration portion 17 is provided at the portions of the third virtual folding lines 22 and 22 and the fourth virtual folding lines 23 and 23 shown in FIG. 1. Two first locking pieces 18 and a first locking piece 19 are formed on the inner side of the corner decoration 17 and are appropriately formed integrally with the hook 16 of the corner decoration 17 while being bent several times on the back side. Each is bent and locked.
[0010]
As shown in FIGS. 6 to 7, the roof corner ornament 24 of the present invention is bent at a predetermined angle corresponding to the angle of the descending ridge 27a of the dormitory roof 27 shown in FIG. doing.
When the roof corner ornament 24 is thus configured as described above, it is formed of a single plate, so that the number of parts can be reduced, the processing can be easily performed, and it can be supplied at low cost. Further, the roof corner ornament 24 is manufactured in advance in a factory, and therefore, there is an effect that, in the construction, it does not take time and effort in the one-touch process.
Further, if the roof corner ornament 24 is used, it is easy to connect roof plates, and it is excellent as a decorative ornament.
[0011]
FIGS. 9-10 is a partial explanatory view for demonstrating the 1st and 2nd procedure which constructs the ridge roof 27 using the corner decoration 24 for roofs of this invention.
When sequentially attaching the roof corner ornament 24 to the descending ridge 27a of the dormitory roof 27, first, in the first procedure, as shown in FIG. A long metal roof plate 29 is placed on the roof base plate 28 of the descending wing 27a, and is formed in the gap formed between the corner decoration overlap portions 25 and 25 and the overhang portions 14 and 14, respectively. , 29 are inserted from the left and right sides, and the edge portions 29a, 29a of the long metal roof plates 29, 29 are covered with nails or the like through roof mounting brackets (hangers, etc.) 30, 30. It fixes to the base plate 28, respectively.
[0012]
Next, in the second procedure, as shown in FIG. 10, the same roof corner ornament 24 next to the lowest roof corner ornament 24 is placed on the roof base plate 28 of the descending wing 27a. In the same manner, the side edges of the long metal roof plates 29, 29 are placed in the gaps formed between the corner decoration portions 25, 25 and the overhanging portions 14, 14, respectively. The edge portions 29a, 29a of the long metal roof plates 29, 29 are fixed to the roof base plates 28, 28 with nails or the like through the roof mounting brackets (hangers, etc.) 30, 30, respectively. To do.
In this manner, as in the first procedure, the roof corner ornament 24 and the long metal roof plates 29 and 29 are fixed on the roof base plate 28 of the descending wing 27a, and sequentially up to the top. Raised and constructed a dormitory roof 27 as shown in FIG.
Therefore, since the construction does not require sheet metal processing at the site, the one-touch process is extremely simple, and there is an effect that the labor of a skilled worker is not bothered.
In addition, in the Example of this invention, although the metal roof board was made into the elongate metal roof board, of course, it is not restricted to this.
[0013]
【The invention's effect】
As described above, according to the metal plate roofing construction method using the corner ornament for roof according to the present invention, the corner ornament for roof and the metal roof plate can be assembled in a one-touch process without taking time and workability is improved. Good, no need for skilled workers, safe and cost-effective.
Also, the roof corner ornaments are made of a single plate, so the number of parts is small, processing is easy, and they can be manufactured at the factory in advance, so that they can be supplied at a low cost and rainwater does not easily enter after construction. Therefore, it is easy to connect the roof boards, and it has the effect of being excellent as a decorative ornament.
