Description

本発明は、屋根の改修に際し既設屋根材の上に新設金属屋根材が葺かれる改修金属屋根の軒先構造に関する。   The present invention relates to an eaves-end structure of a modified metal roof in which a new metal roof material is spread on an existing roof material when the roof is modified.

この種の改修金属屋根の軒先構造として、例えば、図7に示すように、既設屋根材41の上に新設金属屋根材42が、新設金属屋根材42の軒先側端42aが既設屋根材41の軒先側端41aよりも棟側方向に所定間隔Hだけずれた位置になるように葺かれ、新設金属屋根材42の軒先部を覆う新設軒先唐草(軒先包み)43が新設金属屋根材42の軒先方向に露出する既設屋根材41の露出部41bの上に敷設されるものがある(特許文献1参照)。
これによれば、新設金属屋根材42の軒先側端42aが既設屋根材41の軒先側端41aよりも棟側方向に所定間隔だけずれた位置になるように葺かれるので、新設金属屋根材42の軒先側端42aを既設屋根材41の軒先側端41aに揃えて葺く改修工法の場合のように、新設金属屋根材42の軒先の、既設軒樋44からの高さが、高くなるようなことがなくなる。したがって、屋根の改修に際し既設軒樋44は付け直すことなく既設状態のままにしておいても、新設金属屋根板42を流れる雨水は既設軒樋44を飛び越えて流れ落ちるようなことがなく、既設屋根材41の露出部の上に敷設された新設軒先唐草43の上を伝ってから既設軒樋44に確実に流入する。
As an eaves tip structure of this type of modified metal roof, for example, as shown in FIG. 7, a new metal roof material 42 is formed on an existing roof material 41, and an eaves side end 42 a of the new metal roof material 42 is an existing roof material 41. A new eaves arabesque (eave wrapping) 43 covering the eaves of the new metal roofing material 42 is wound at a position shifted by a predetermined distance H in the ridge side direction from the eaves side end 41a. Some are laid on the exposed portion 41b of the existing roof material 41 exposed in the direction (see Patent Document 1).
According to this, the eaves side end 42a of the new metal roofing material 42 is wound so as to be shifted from the eaves side end 41a of the existing roofing material 41 by a predetermined distance in the ridge side direction. The height of the eaves of the new metal roofing material 42 from the existing eaves eaves 44 is increased as in the case of the repair method in which the eaves side end 42a is aligned with the eaves side end 41a of the existing roofing material 41. There is nothing wrong. Therefore, even if the existing eaves 44 are not reattached when the roof is repaired, the rainwater flowing through the new metal roof plate 42 does not jump over the existing eaves 44 and does not flow down. After passing over the new eaves arabesque 43 laid on the exposed portion of the material 41, it surely flows into the existing eaves basket 44.

特開平10−131412号公報JP-A-10-131212

上記従来の改修金属屋根の軒先構造では、新設軒先唐草43を既設屋根材41に固定するにあたり、該新設軒先唐草43の、既設屋根材41の露出部41bを覆う屋根載置部43aにセルフドリリングビス45を打ち込んで既設屋根材41に固定し、更に該セルフドリリングビス45の打込箇所に該ビス頭部を覆うように防水シート46を被着させている。しかしながら、かかるセルフドリリングビス45の打込箇所は、新設金属屋根材42の軒先側端部の裏面側であって軒先部からの雨水が浸入しやすい箇所であるため、防水シート46を被着させるだけでは防水対策が十分なものとはいえなかった。また、新設金属屋根材42の軒先側端部の裏面部に、セルフドリリングビス45の頭部との当接を避けるために切欠部47を形成するとなると、新設金属屋根材42を軒先側の正面から切欠部47がよく見えるため改修屋根の美観を損ないやすい。   In the above-described conventional eaves structure of a modified metal roof, when the newly installed eaves arabesque 43 is fixed to the existing roofing material 41, the new eaves arabesque 43 self-drills to the roof mounting portion 43a covering the exposed portion 41b of the existing roofing material 41. A screw 45 is driven in and fixed to the existing roofing material 41, and a waterproof sheet 46 is attached to the driving site of the self-drilling screw 45 so as to cover the screw head. However, since the place where the self-drilling screw 45 is driven is the back side of the end of the eaves side of the new metal roofing material 42 and rainwater from the eaves is likely to enter, the waterproof sheet 46 is attached. It could not be said that waterproofing was enough. Moreover, when the notch part 47 is formed in the back surface part of the eaves side edge part of the new metal roofing material 42 in order to avoid contact | abutting with the head part of the self-drilling screw 45, the new metal roofing material 42 is made into the front of the eaves side. Since the cutout 47 can be seen well, the aesthetic appearance of the repaired roof is likely to be impaired.

本発明の目的は、上記のような、新設金属屋根材の軒先側端が既設屋根材の軒先側端よりも棟側方向に所定間隔だけずれた位置になるように葺かれる改修金属屋根の軒先構造において、新設金属屋根材として凹凸立体感に富む金属成形瓦のようなデザインを呈する横葺屋根材を採用し、この新設金属横葺屋根の軒先部まわりの雨仕舞いの向上を図れ、また外観意匠に優れる改修金属屋根の軒先構造を提供することにある。   The object of the present invention is as described above, wherein the eaves end of the repaired metal roof is sown so that the eaves side end of the new metal roofing material is shifted by a predetermined distance in the ridge side direction from the eaves end side of the existing roofing material. In the structure, we adopt a horizontal roofing material that has a design like a metal roof tile with rich unevenness as a new metallic roofing material, and it is possible to improve the rain finish around the eaves of this new metallic roofing roof, and the appearance The object is to provide an eaves-end structure of a modified metal roof that excels in design.

In order to achieve the above object, the eaves structure of a modified metal roof as a premise of the present invention will be described with reference to the reference numerals attached to FIGS. 1 to 6 to facilitate understanding of the contents of the invention. The new metal roof material (6) in the forefront row on the material (2) is such that the eaves end (6a) of the new metal roof material (6) is more than the eaves end (2a) of the existing roof material (2). The arabesque main surface portion (23) and the roof mounting portion (24) continuously provided in the ridge side direction from the upper end of the arabesque main surface portion are wound so as to be shifted by a predetermined interval (H) in the ridge side direction. The newly established eaves arabesque (8) covers the eaves of the existing roofing material (2) with the arabesque main surface (23), and the roof mounting part (24) is exposed in the direction of the eaves of the new metal roofing material (6). It is installed so as to be laid on the exposed portion of the existing roof material (2).
In addition, the present invention provides a main surface plate portion (12) in which the new metal roofing material (6) is provided with main surface concave portions (10) and main surface convex portions (11) extending in the left-right lateral direction extending in the eaves-ridge direction. And a front convex part (13) continuous downward from the eaves side end of the main surface plate part and continuing to the eaves side end of the main surface concave part (10), and an eaves side end of the main surface convex part (11) A front plate portion (15) having a continuous front concave portion (14), and folded back from the lower end of the front plate portion (15) toward the ridge side to be continuous with the front convex portion (13) and the front concave portion (14), respectively. Consisting of a reed roofing material comprising an engagement piece recess (16) and a front engagement piece (18) having an engagement piece projection (17);
The roof mounting part (24) of the new eaves arabesque (8) has a convex part (26) and a concave part (25) corresponding to the engaging piece concave part (16) and the engaging piece convex part (17), respectively. Being formed into a shape,
