[0001]
[Industrial application fields]
TECHNICAL FIELD The present invention relates to a decorative tile rod that is attached to a horizontal roof using a metal roof plate to give an accent to a building.
[0002]
[Prior art]
Metal roofs are used in various buildings such as general houses and public facilities because they are relatively light and have a low load on the underlying framework structure and can be easily combined using nails and screws.
In roof ridges using a metal roof, a horizontal roofing method is frequently used because unit roof plates formed in a predetermined size are used. In the horizontal method, as shown in FIG. 1, after fixing the eaves side metal roof plate 1 to the base plate 2 with nails, screws, bolts, etc., the eaves side metal roof plate 1 is attached to the locking projection 1a on the ridge side. The ridge side metal roof plate 1 connected to the eaves side metal roof plate 1 is fixed to the base plate 2 by engaging the locking recesses 1 b of the ridge side metal roof plate 1. Thereafter, the metal roof plate 1 is laid from the eaves to the building side by the same operation.
Since the metal roofing board 1 that has been laid down is spread on the entire surface of the roof in a flat state, the impression given to the viewer is weak. Therefore, recently, a decorative roof bar 3 extending from the eaves to the ridge is attached to the side roof, and the roof is accented. The present inventors have also developed a horizontal roof with a decorative tile rod, and some of them were introduced in Japanese Patent Laid-Open Nos. 9-195450 and 9-324506.
[0003]
Since the horizontal metal roof plate 1 has a flat surface in the lateral direction, a mounting bracket 4 as shown in FIG.
The mounting bracket 4 includes a tongue piece 4 a that is inserted into a connecting portion between the eaves side metal roof plate 1 and the ridge side metal roof plate 1. A presser piece 4b is raised on the opposite side of the tongue piece 4a. A bolt 4e is fixed to the tongue piece 4a, and a nut 4f is screwed into the tip of the bolt 4e protruding through the bolt hole. When the nut 4f is tightened, the presser piece 4b is elastically deformed and approaches the tongue piece 4a. Rivet holes 4 c are formed in the mounting bracket 4 on the left and right.
[0004]
As shown in FIG. 4, the mounting bracket 4 has a tongue piece 4 a inserted in a gap at a connecting portion between the eaves side metal roof plate 1 and the ridge side metal roof plate 1. After the tongue piece 4a is inserted, the nut 4f is screwed into the bolt 4e, and the eaves side end of the ridge side metal roof plate 1 is sandwiched between the tongue piece 4a and the holding piece 4b, so that the mounting bracket 4 is fixed. The
On the other hand, as shown in FIG. 3, the decorative tile rod 3 has a substantially semicircular cross section as shown in FIG. 3, and the inwardly bent portion 3 b bent inwardly fits the steps of the metal roof plates 1, 1. A step 3c is attached.
Next, the decorative roof rod 3 is applied so as to cover the mounting bracket 4, the rivet holes 4 c of the mounting bracket 4 are aligned with the rivet holes 3 a formed on the left and right sides of the decorative roof rod 3, The decorative tile rod 3 is riveted to the rivet hole 4c, and the decorative tile rod 3 is attached to the entire metal roof plates 1 and 1 so that there is no gap.
[0005]
[Problems to be solved by the invention]
Since the conventional decorative tile rod 3 as described above is fixed by the mounting bracket 4, the mounting bracket 4 is required for each connecting portion of the metal roof plates 1 and 1. For this reason, not only will material costs and man-hours increase, but the entire roof will become heavier, and the merits of a metal roof that should be light and strong will be somewhat impaired. On the other hand, if the number of mounting brackets 4 is reduced, the strength against wind pressure and the like is reduced, and the decorative tile rod 3 and thus the mounting bracket 4 are easily lifted in the middle of the mounting brackets 4 and 4. If the gap between the metal roofing board 1 and the decorative tile rod 3 increases due to the rising of the decorative tile rod 3 and the mounting bracket 4, the appearance of the decorative tile rod 3 is deteriorated as well as the appearance. There is a possibility that the decorative roof bar 3 is detached from the metal roof plate 1 by the blown air.
[0006]
[Means for Solving the Problems]
The present invention has been devised to solve such problems, and even if the mounting position of the decorative tile rod to the metal roof plate by the mounting bracket is minimized, the decorative tile does not impair the mounting strength. An object is to provide a rod mounting structure.
In order to achieve the object, the decorative tile rod mounting structure of the present invention has a semi-hollow body shape that is long in the ridge direction, and the inner bending portion having a step portion is formed at the lower part of the cross section orthogonal to the ridge direction. The insertion piece which protruded in the ridge direction from the said internal bending part of the stick | rod is inserted in the connection part between the eaves side metal roof board and the ridge side metal roof board.
The decorative tile used in this mounting structure can be formed by bending a metal cut plate cut out from a single metal plate.
[0007]
Embodiment
The decorative tile rod 10 used in the mounting structure according to the present invention has a shape as shown in FIG. 5, for example, and is formed from a metal cut plate into a semi-cylindrical shape.
Specifically, it is formed into a semi-hollow body having a plurality of inner bent portions 11 and 11 on the bottom surface with a length W corresponding to the effective length in the ridge direction of the metal roof plate that has been laid side by side. A step 15 corresponding to the height h of the edge of the eaves side of the metal roof slab is formed between each of the inner bent portions 11, 11 extending in the direction of the eave at the step 15. 14 is used. A rivet insertion hole 12 is formed in the eaves side hollow body side wall portion in the vicinity of the eaves side end and near the ridge side end or at an appropriate position therebetween.
[0008]
A stepped portion 15 of the decorative roofing rod is positioned slightly on the eaves side of the stepped portion formed in the latching recess 1b of the horizontal metal roof plate as shown in FIG. The decorative tile rod 10 is pushed up and attached to the ridge side so as to be inserted into the connecting portion between the ridge side locking recess 1b and the eaves side roof plate 1 (FIG. 7). The decorative roof bar 10 is fixed to the metal roof at each step, but if left as it is, it shifts toward the eaves side due to gravity, so that it is prevented by some means. For example, the mounting bracket 4 that has been conventionally used is appropriately attached at two or more positions (every third level in FIG. 7) of the steps of the locking recesses 1b, 1b over the entire length of the decorative tile rod 10, and the rivet insertion holes 12 are provided. The decorative brick 10 is pushed up and fixed.
[0009]
The decorative tile rod 10 according to the present invention is manufactured by cutting the metal plate 16 into a shape in which the insertion piece 14 protrudes from the line of the step portion 15 toward the ridge as shown in FIG. . When the cut metal plate 16 is bent along the fold line BL (b), the insertion piece 14 is formed so as to protrude from the inner bent portion 11 in the ridge direction. Next, the metal plate 16 is bent into a cylindrical shape in the direction in which the inner bent portion 11 is bent, and the decorative tile is extended from the inner bent portion 11 and the insertion piece 14 protrudes toward the ridge as shown in FIG. A rod 10 is formed. For this reason, a new part is not required and it can carry out easily by a bending process by making the shape of the cut-out metal plate 16 into Fig.6 (a).
In addition, since the decorative roof bar 10 is temporarily fixed in the pushed-up state, the riveting operation can be easily performed even when performing a construction process for preventing the displacement such as attaching the mounting bracket 4.
The above description has been made with a semi-circular decorative brick rod, but it goes without saying that it can also be applied to a rectangular or pentagonal decorative brick rod.
[0010]
【The invention's effect】
As described above, in the side roof roof decorative tile rod mounting structure according to the present invention, the insertion piece formed to extend from the inner bent portion at the stepped portion at the lower end of the decorative tile rod and project toward the ridge side. However, it is inserted in the connection part between the eaves side metal roof board and the ridge side metal roof board. For this reason, since the number of mounting brackets can be reduced while maintaining the mounting strength against wind pressure or the like, the construction becomes easy, the cost can be reduced, and the metal roof can be reduced in weight.
