By using the mounting bracket according to the present invention, it is possible to form a roof without using rafters, which are generally used square timbers. In order to provide rafters, it is necessary to fix the rafters with nails at the corners of the timbers (purlins) that support the rafters, and in this case, grooves for fitting the rafters may be formed at the corners of the purlins. Such work requires skill and must be carried out at a high place where the foothold is poor.
On the other hand, the use of the mounting bracket according to the present invention does not require the installation of rafters or the processing of the purlin as described above, and thus has the effect of reducing the cost and the construction period.
In addition, the mounting bracket according to the present invention is designed to provide a gap through which air can pass without directly contacting the back surface of the roof plate with a beam or a ridge that is a square member supporting the roof plate. This has the effect of preventing deterioration of the roof plate due to retention of water.
以下、本発明を実施するための形態について図を用いて説明する。
図１は、本発明を用いた家屋１の屋根２の構造を概略的に表した説明図である。同図は、一例として単純な切り妻と称される形態の屋根２の片側面の構造を概略的に表したものであり、中央上部の棟部分を稜線状の頂部として両側の桁側に向かって下降傾斜した斜面を有する形態を表している。
なお当然ながら、本発明は単純な切り妻型の屋根に関わらず、他の形態の屋根にも適用可能であることは言うまでも無い。
Hereinafter, modes for carrying out the present invention will be described with reference to the drawings.
FIG. 1 is an explanatory view schematically showing the structure of a roof 2 of a house 1 using the present invention. As an example, this figure schematically shows the structure of one side of a roof 2 in the form of a simple gable, and the ridge part at the center upper part is used as a ridge-shaped top toward the girders on both sides. 2 shows a form having a slope inclined downward.
Of course, it goes without saying that the present invention is applicable to roofs of other forms, regardless of the simple gabled roof.
屋根２は、桁３、梁４、束５（５ａ、５ｂ）、母屋６、棟木７等からなる骨格部材と屋根板８を有しており、屋根板８の表面には瓦やスレートといった屋根材（図示せず）を設けるようになっている。骨格部材は、常法に従って構築され傾斜した屋根板８の荷重を支える構造を形成している。
桁３は、家屋の外壁上部において、図面の奥行き方向に亘って設けられる角材であり、後述する取付金具１０を介して屋根板８を支えるようになっている。棟木７は、束５ａの最上部において、図面の奥行き方向に亘って設けられる角材であり、束５ａとともに後述する取付金具１０を介して屋根板８を支えるようになっている。
また、中央上部の棟部分には、屋根材を配置した後に当該部分を覆う棟包み板９を設け、屋根の頂部となる棟木７部分からの雨の侵入を防止するようになっている。
The roof 2 has a skeleton member including a girder 3, a beam 4, a bundle 5 (5a, 5b), a purlin 6, a purlin 7, and the like, and a roof plate 8 on the surface of the roof plate 8 such as roof tiles and slate. A material (not shown) is provided. The skeleton member is constructed according to a conventional method and forms a structure for supporting the load of the inclined roof plate 8.
The girder 3 is a square member provided over the outer wall of the house in the depth direction of the drawing, and supports the roof plate 8 via a mounting bracket 10 described later. The purlin 7 is a square member provided at the top of the bundle 5a in the depth direction of the drawing, and supports the roof plate 8 together with the bundle 5a via a mounting bracket 10 described later.
In addition, a ridge-wrapping plate 9 is provided on the ridge portion in the upper center to cover the portion after arranging the roofing material so that rain can be prevented from intruding from the ridge tree 7 portion that is the top of the roof.
垂木の敷設を必要とする一般的な従来の屋根構造では、屋根板として「野地板」と称されている肉厚が９〜１２ｍｍ程度の合板を使用する。これに対して本実施の形態で用いる屋根板８は、肉厚が２４ｍｍ程度の合板を用いている。外形は、従来の野地板と同様に略９００×１８００ｍｍ程度である。
この肉厚の合板は、一般的な肉厚（９〜１２ｍｍ）の板と比較して強度があって撓みにくく、一般的な成人男性が乗っても踏み抜くことのない強度を有している。
なお、屋根板８は上記のような積層型の一枚板によって形成する場合の他、表裏の板材の間に格子状の補強フレームを内蔵して強度を高めた屋根板を用いてもよい。
In a general conventional roof structure that requires the installation of rafters, plywood having a wall thickness of about 9 to 12 mm, which is referred to as a "field board", is used as a roof board. On the other hand, the roof plate 8 used in the present embodiment uses plywood having a wall thickness of about 24 mm. The outer shape is about 900 × 1800 mm, which is the same as the conventional ground board.
This thick plywood has strength and is less likely to bend than a general wall thickness (9 to 12 mm), and has a strength that a general adult man does not step on. ..
In addition to the case where the roof plate 8 is formed of the above-mentioned laminated type single plate, a roof plate having a lattice-like reinforcing frame built in between the front and back plate members to increase the strength may be used.
本実施の形態に係る屋根２の構造についてさらに詳しく説明する。従来一般的な屋根の形成方法は、垂木と称する角材を棟木から桁に亘って複数本並べて配置し、この垂木に対して屋根板となる野地板を貼り付け、この野地板の表面にスレートや瓦といった屋根材を設けるというものである。
これに対して本実施の形態では、垂木を使用せずに屋根板８を設けることを特徴とする。前述したように単体において曲げや撓みに強く、屋根板８は従来の野地板よりも高い強度を有している。
具体的には、垂木に取り付けた野地板と同程度の強度を有するように構成するのが好ましい。このため、屋根板８には、合板としての肉厚を従来のものよりも肉厚に構成するか、構造的に強化した板材を使用する。
The structure of the roof 2 according to this embodiment will be described in more detail. Conventionally, a common roof is formed by arranging multiple timbers called rafters side by side from the purlins to the girders, attaching a roof plate to the rafters, and applying a slate or a slate to the surface of the roof plate. It is to provide roofing materials such as roof tiles.
On the other hand, the present embodiment is characterized in that the roof plate 8 is provided without using rafters. As described above, the roof plate 8 is strong against bending and bending as a single body, and the roof plate 8 has higher strength than the conventional base plate.
Specifically, it is preferable to have a strength similar to that of the field board attached to the rafter. For this reason, the roof plate 8 is made of a plywood plate which is thicker than the conventional one or is structurally reinforced.
屋根２は、骨格部材の中で最も高さの高い棟木７若しくは束５ａの先端から最も高さの低い桁３に亘るように傾斜させた屋根板８を設けるが、この屋根板８を取付金具１０を介して棟木７若しくは束５ａと桁３のそれぞれに固定している。また、傾斜した屋根板８の中間付近を、取付金具３０を介して束５ｂの頂部に取り付けている。言い換えるならば、屋根板８は骨格部材に対して取付金具１０，３０を介して取り付けられている。 The roof 2 is provided with a roof plate 8 that is inclined so as to extend from the tip of the purlin 7 having the highest height among the frame members or the bundle 5a to the girder 3 having the lowest height. It is fixed to each of the purlin 7 or the bundle 5a and the girder 3 via 10. Further, the vicinity of the middle of the inclined roof plate 8 is attached to the top of the bundle 5b via the attachment fitting 30. In other words, the roof plate 8 is attached to the skeletal member via the attachment fittings 10 and 30.
以下、屋根板８を骨格部材に取り付ける取付金具１０，３０について説明する。
本実施の形態では、棟木７若しくは束５ａと桁３に屋根板８を取り付ける金具として、図２に示す取付金具１０を使用する。図２（ａ）は取付金具１０の正面図、図２（ｂ）は取付金具１０の側面図を表している。
取付金具１０は、長方形状の一枚の板材を長辺に直交する折り曲げ部１１を境界として曲げ加工した板金部材として構成されている。そして、折り曲げ部１１を境界とした一方（図の下方）の側を棟木７若しくは桁３等に固定する固定部（固定手段）１２、他方（図の上方）の側を屋根板８の裏面と直接接触する取付面（平面部）１９を有した支持部１３として構成したものである。
Hereinafter, the mounting brackets 10 and 30 for mounting the roof plate 8 to the frame member will be described.
In the present embodiment, the metal fitting 10 shown in FIG. 2 is used as the metal fitting for attaching the roof plate 8 to the purlin 7 or the bundle 5a and the girder 3. 2A shows a front view of the mounting bracket 10, and FIG. 2B shows a side view of the mounting bracket 10.
The mounting member 10 is configured as a sheet metal member obtained by bending a single rectangular plate material with a bent portion 11 orthogonal to the long side as a boundary. Then, one side (lower side in the figure) with the bent portion 11 as a boundary is a fixing portion (fixing means) 12 that is fixed to the purlin 7 or the girder 3, and the other side (upper side in the figure) is the back surface of the roof plate 8. The support portion 13 has a mounting surface (flat surface portion) 19 that is in direct contact with the support portion 13.
固定部１２は、棟木７と桁３等の側面に接触する矩形の平面部１４と、平面部１４の上端に相当する部位に設けた係合片１５、平面部１４の下縁の両角部に設けた食い込み片１６、１６を有している。
係合片１５は、折り曲げによって固定部１２と取付面１９を形成する前に、固定部１２から取付面１９に亘る領域の一部を打ち抜き、その打ち抜いた部分を平面部１４に対して直交するように折り曲げた部位である。食い込み片１６は、平面部１４下縁の両角部を潰して平面部１４側に突出させた部位である。
The fixing portion 12 has a rectangular flat surface portion 14 that comes into contact with the side surfaces of the purlin 7 and the girder 3, an engaging piece 15 provided at a portion corresponding to the upper end of the flat surface portion 14, and both corners of the lower edge of the flat surface portion 14. It has the biting pieces 16 and 16 provided.
Before forming the fixing portion 12 and the mounting surface 19 by bending, the engaging piece 15 punches out a part of a region extending from the fixing portion 12 to the mounting surface 19, and the punched portion is orthogonal to the flat surface portion 14. It is the part that is bent like this. The bite piece 16 is a portion in which both corners of the lower edge of the flat surface portion 14 are crushed and protruded toward the flat surface portion 14 side.
取付金具１０が棟木７と桁３に装着される際、角材によって形成されている棟木７や桁３の側面に平面部１４が接触するとともに、係合片１５が棟木７や桁３の上面に接触する。
すなわち、棟木７や桁３の角を利用して取付金具１０の固定位置が定まり、この固定姿勢の状態で、固定用の小孔１７を通して取り付けたビスNによって取付金具１０が固定される。係合片１５は、固定位置を規定する作用の他、上方から作用する荷重を棟木７や桁３の上面によって支えることを可能にし、ビスNとともに屋根の荷重を支えるようになっている。このような構造により、小さな取付金具１０であっても、大きな荷重を支えることが可能になっている。
When the mounting bracket 10 is attached to the purlin 7 and the girder 3, the flat surface portion 14 comes into contact with the side surfaces of the purlin 7 and the girder 3 formed of square timbers, and the engaging pieces 15 are attached to the upper surfaces of the purlin 7 and the girder 3. Contact.
That is, the fixing position of the mounting member 10 is determined by utilizing the corners of the purlin 7 and the girder 3, and in this fixed state, the mounting member 10 is fixed by the screw N mounted through the fixing small hole 17. In addition to the action of defining the fixed position, the engagement piece 15 enables the load acting from above to be supported by the purlin 7 and the upper surface of the girder 3, and supports the load of the roof together with the screw N. With such a structure, even a small mounting member 10 can support a large load.
支持部１３は、固定部１２を構成する平面部１４に対して傾斜させた、屋根板８の裏面に対して接触する取付面１９を有している。また、この取付面１９の上縁両端に、両角部を潰して屋根板８側に突出させた食い込み片２０を設けている。
屋根板８は、勾配を設けて取り付けられるので、水平方向に対して傾斜している。この屋根板８の傾斜に対して、取付面１９は屋根板８の勾配角度よりも大きな角度を有するように形成される。具体的な例としては、水平方向に対する屋根板８の勾配角度が１０度であるならば、水平方向に対する取付面１９の角度は１５度、水平方向に対する屋根板８の勾配角度が１５度であるならば、水平方向に対する取付面１９の角度は２０度を成すように形成される。
The support portion 13 has a mounting surface 19 that is inclined with respect to the flat surface portion 14 that forms the fixed portion 12 and that contacts the back surface of the roof plate 8. Further, at both ends of the upper edge of the mounting surface 19, there are provided biting pieces 20 that are crushed at both corners and projected toward the roof plate 8 side.
Since the roof plate 8 is attached with a slope, it is inclined with respect to the horizontal direction. The mounting surface 19 is formed to have an angle larger than the inclination angle of the roof plate 8 with respect to the inclination of the roof plate 8. As a specific example, if the inclination angle of the roof plate 8 with respect to the horizontal direction is 10 degrees, the angle of the mounting surface 19 with respect to the horizontal direction is 15 degrees, and the inclination angle of the roof plate 8 with respect to the horizontal direction is 15 degrees. Then, the angle of the mounting surface 19 with respect to the horizontal direction is formed to be 20 degrees.
上記のように、屋根板８の勾配角度よりも取付面１９の角度を大きくすると、屋根板８を載せる際に最初に食い込み片２０が刺さり、取付面１９の上縁が下方に押された状態になる。
上縁が下方に押された取付面１９は、折り曲げ部１１付近を中心に曲がり取付面１９全体が屋根板８の裏面に接触するまで下方へ傾く。すなわち、屋根板８の接触に伴い取付面１９全体が接触するように角度が自動調節されるものであり、逆を言えばこのような自動調節ができるように支持部１３の素材と形状が定められている。また、屋根板８を取り付ける際の滑り止めとしての作用も有している。
屋根板８と取付面１９の結合は、屋根板８の表面側から打ち込んだねじ釘Ｋによって行われる。ねじ釘Ｋは、打ち込まれると屋根板８を貫通するとともに取付面１９に孔を開け、ネジ部によって屋根板８と取付面１９を結合する。
As described above, when the angle of the mounting surface 19 is made larger than the inclination angle of the roof plate 8, the biting piece 20 is pierced first when the roof plate 8 is placed, and the upper edge of the mounting surface 19 is pushed downward. become.
The mounting surface 19 whose upper edge is pressed downward bends around the bent portion 11 and tilts downward until the entire mounting surface 19 contacts the back surface of the roof plate 8. That is, the angle is automatically adjusted so that the entire mounting surface 19 comes into contact with the contact of the roof plate 8, and conversely, the material and shape of the support portion 13 are determined so that such automatic adjustment can be performed. Has been. It also has a function as a slip stopper when the roof plate 8 is attached.
The roof plate 8 and the mounting surface 19 are coupled with each other by a screw nail K driven from the front surface side of the roof plate 8. When the screw nail K is driven, it penetrates the roof plate 8 and makes a hole in the mounting surface 19, and the roof plate 8 and the mounting surface 19 are connected to each other by the screw portion.
また、棟木７若しくは束５ａ又は桁３の上面と接触する係合片１５と、屋根板８に接触する取付面１９との間には、数センチメートルの間隔が開くように間隔部２１を設けている。この間隔部２１は、平面部１４をそのまま延長した板状の部分であるが、屋根板８とこれを取り付けた棟木７等とを近接させず、空気の流通が可能となる隙間を開けるために設けている。
また、間隔部２１の両側を平面部１４側に変形させて突出させた変形部２２を形成しているので、当該部位による補強作用によって搭載した屋根板８の荷重等によって屈曲しないように強度が高められている。
A space 21 is provided between the engagement piece 15 that contacts the purlin 7 or the bundle 5a or the upper surface of the girder 3 and the mounting surface 19 that contacts the roof plate 8 so that a space of several centimeters is formed. ing. The spacing portion 21 is a plate-shaped portion obtained by extending the flat portion 14 as it is, but in order to open a gap that allows air to flow without bringing the roof plate 8 and the purlin 7 and the like having the roof plate 8 close to each other. It is provided.
Further, since the deformed portions 22 are formed by deforming both sides of the spacing portion 21 toward the flat surface portion 14 side and projecting, the strength is such that the roof portion 8 mounted thereon is not bent due to the reinforcing action of the portion. Has been raised.
次に、図３、図４を用いて屋根の骨格部材中の最高地点である棟木７と、最低地点である桁３の中間地点に設ける取付金具３０について説明する。この中間地点においても前述した取付金具１０と同様の金具を使用することも可能であるが、より最適な構造として取付金具３０を用いた場合について説明する。
取付金具３０は、Ｌ字状に形成した支持部３１と、支持部３１を支える固定部３２を強度のある鉄等の金属によって一体的に形成したものである。支持部３１は、内面に母屋６と称する角材を介して間接的に屋根板８の裏面を支える取付面３４を有するとともに、母屋６の側面を支える支持面３５を形成した部位である。支持面３５を構成する板状部分には、取付面３４によって下面を支えた母屋６をビスによって固定するための孔３６が複数個設けられている。L字状に形成した取付面３４と支持面３５の内面に装着した母屋６は、孔３６に挿通させたビスNによって固定させるようになっている。
Next, the purlin 7 that is the highest point in the frame member of the roof and the mounting bracket 30 that is provided at the middle point of the girder 3 that is the lowest point will be described with reference to FIGS. 3 and 4. Although it is possible to use a metal fitting similar to the above-described mounting metal fitting 10 at this intermediate point, a case where the mounting metal fitting 30 is used as a more optimal structure will be described.
The mounting member 30 is formed by integrally forming an L-shaped support portion 31 and a fixing portion 32 that supports the support portion 31 with a metal such as strong iron. The support part 31 is a part having an inner surface having a mounting surface 34 that indirectly supports the back surface of the roof panel 8 via a square bar called the purlin 6 and a support surface 35 that supports the side surface of the purlin 6. A plurality of holes 36 for fixing the purlin 6 whose lower surface is supported by the mounting surface 34 with screws are provided in the plate-shaped portion forming the support surface 35. The purlin 6 mounted on the inner surfaces of the L-shaped mounting surface 34 and the support surface 35 is fixed by a screw N inserted into the hole 36.
取付面３４の裏面には、板状の固定部３２が裏面に対して直交するように設けられている。固定部３２の下方には貫通孔３７が形成されており、当該部位を骨格部材の一種である束５ｂの先端に形成した切り込み３８内に装着し、切り込み３８内に貫通させた金属製の丸棒として形成されたドリフトピン３９を挿通させることで、取付金具３０が揺動可能に取り付けられている。
取付金具３０の特徴は、角材である母屋６の角度を屋根板８に合わせて自動調節されるように構成したことである。これにより取付金具３０は、骨格部材に対する屋根板８の取付角度に応じて屋根板８と接する母屋６を適切な角度に傾けることができるので、屋根板８の傾斜に応じた最適な状態で取り付けを行うことができるようになっている。
A plate-shaped fixing portion 32 is provided on the back surface of the mounting surface 34 so as to be orthogonal to the back surface. A through hole 37 is formed below the fixing portion 32, and the portion is mounted in a notch 38 formed at the tip of the bundle 5b, which is a kind of skeletal member, and is made of a metal circle penetrated into the notch 38. The mounting bracket 30 is swingably mounted by inserting the drift pin 39 formed as a rod.
A feature of the mounting bracket 30 is that the angle of the purlin 6 which is a square member is automatically adjusted according to the roof plate 8. As a result, the mounting bracket 30 can tilt the purlin 6 in contact with the roof plate 8 at an appropriate angle according to the mounting angle of the roof plate 8 with respect to the skeletal member, so that the mounting bracket 30 can be mounted in an optimal state according to the inclination of the roof plate 8. To be able to do.
改めて、図１を用いて屋根板８の取付構造について説明すると、図１に示した棟木７、桁３は図の奥行き方向に亘る長尺の角材として設けられている。図１には、棟木７の断面、桁３の側面が表されている。この棟木７と桁３の長手方向（図面の奥行き方向）に沿って、前述した取付金具１０が複数個配置され、この取付金具１０を介して屋根板８が取り付けられる。
また、束５ｂは垂直上方に向かって立設した角材であり、図の奥行き方向に亘って多数設けられている。各束５ｂの上部先端には、前述したように取付金具３０が設けられる。各取付金具３０には、図の奥行き方向に掛け渡された角材である母屋６が固定され、屋根板８の傾斜角度に応じて自動調節的に傾いた状態で屋根板８を固定するようになっている。
The mounting structure of the roof plate 8 will be described again with reference to FIG. 1. The purlin 7 and the girder 3 shown in FIG. 1 are provided as long square members extending in the depth direction of the drawing. FIG. 1 shows a cross section of the purlin 7 and a side surface of the girder 3. A plurality of the mounting brackets 10 described above are arranged along the longitudinal direction (depth direction of the drawing) of the purlin 7 and the girder 3, and the roof plate 8 is mounted through the mounting brackets 10.
In addition, the bundle 5b is a square bar that is erected vertically upward and is provided in large numbers in the depth direction of the drawing. The mounting bracket 30 is provided at the top end of each bundle 5b as described above. The purlin 6 which is a square timber suspended in the depth direction of the drawing is fixed to each of the mounting brackets 30, and the roof plate 8 is fixed in a state where the roof plate 8 is automatically adjusted and tilted according to the tilt angle of the roof plate 8. Is becoming
上記のように、取付金具１０を使用すると屋根板８と棟木７や桁３との間に隙間が形成されるので、当該部位における水分の滞留を防止し屋根の劣化を防止する作用を有する。また、軒部や棟付近から空気の侵入が可能になり、屋根裏空間の換気効果をもたらすようになっている。
また、取付金具３０を介して取り付けた母屋６は、屋根板８の傾斜角度に応じて自動調節的に傾き、角材の上面全体を屋根板８の裏面に接触させるようになっている。従来工法では母屋は野地板に対して傾いていないため、母屋の角部分に釘を打ち付けて垂木を固定し、さらにこの垂木に対して野地板を取り付けるようになっていた。母屋の角部分に対する垂木等の固定は、熟練を要するものであり、かつ不安定な足場での作業を強いるものであった。これに対して、本実施の形態では角材の角に釘を打つ必要がないので、比較的簡単かつ安全に作業を行うことができるものとなっている。
As described above, when the mounting bracket 10 is used, a gap is formed between the roof plate 8 and the purlin 7 or the girder 3, so that it has an effect of preventing moisture from staying at the relevant portion and preventing deterioration of the roof. In addition, air can enter from the eaves and the vicinity of the ridge, providing a ventilation effect for the attic space.
The purlin 6 mounted via the mounting bracket 30 is automatically tilted according to the tilt angle of the roof plate 8 so that the entire upper surface of the timber is brought into contact with the back surface of the roof plate 8. In the conventional method, the purlin is not tilted with respect to the baseboard, so nails are fixed to the corners of the purlin to fix the rafters, and then the baseboards are attached to the rafters. Fixing rafters and the like to the corners of the purlin requires skill and requires work on an unstable scaffold. On the other hand, in the present embodiment, since it is not necessary to drive a nail into the corner of the timber, the work can be performed relatively easily and safely.
また、上記の取付金具３０は、図１において点線Ａで囲った部位にように角材である束５ｂの上部先端に取り付けるように構成したが、この部位を点線Ｂで囲ったような構造に置き換えることが可能である。
点線Ｂで囲った構造は、角材で構成した束５ｂを金属製の支柱４０に代えたものである。支柱４０は、両端部にボルト状のネジを形成したネジシャフト４１と、このネジシャフト４１の下端および上端のネジ部に螺合する嵌合部を設けた端金具４２、４３を有している。
Further, the mounting bracket 30 is configured to be mounted on the tip of the upper portion of the bundle 5b which is a square member like the portion surrounded by the dotted line A in FIG. 1, but this portion is replaced with the structure surrounded by the dotted line B. It is possible.
The structure surrounded by the dotted line B is a structure in which the bundle 5b made of square members is replaced with the metal support columns 40. The support column 40 has a screw shaft 41 having bolt-shaped screws formed at both ends, and end fittings 42 and 43 having fitting portions screwed into the screw portions at the lower end and the upper end of the screw shaft 41. ..
下端の端金具４２は、骨格部材の一部に取り付けられ、ネジシャフト４１を垂直上方に立てた状態で保持されるように取り付けられる。また、上端の端金具４３は、前述した取付金具３０を回動可能に支持する部材として構成されている。
端金具４２と端金具４３は、ネジシャフト４１を回転させることによって互いの距離が変わるようになっている。すなわち、ネジシャフト４１の回転に応じて骨格部材に対する上端の端金具４３の高さが変わるので、取付金具３０の高さを屋根板８を固定する高さに合わせて調節することが可能になっている。
The end fitting 42 at the lower end is attached to a part of the skeleton member, and is attached so as to be held in a state where the screw shaft 41 is erected vertically upward. The end fitting 43 at the upper end is configured as a member that rotatably supports the mounting fitting 30 described above.
The distance between the end fitting 42 and the end fitting 43 is changed by rotating the screw shaft 41. That is, since the height of the end fitting 43 at the upper end with respect to the skeleton member changes according to the rotation of the screw shaft 41, the height of the mounting fitting 30 can be adjusted according to the height at which the roof plate 8 is fixed. ing.
また、屋根板８は棟木７から桁３に亘って一枚板である必要はなく、図５に示すように屋根板８ａ、屋根板８ｂのように２枚によって構成してもよい（２枚を超える枚数であっても差し支えない）。この場合、屋根板８ａと屋根板８ｂの接合部分が、取付金具３０に取り付けられた母屋６によって支えられ、両者ともに母屋６に固定される。
このような構造にすると、屋根板８ａと屋根板８ｂを支える取付金具３０が屋根板８ａと屋根板８ｂを連結する接続手段としても作用することになり、複数枚の屋根板によって長い傾斜面を構成する場合であっても、一枚板で構成した屋根板を使用した場合のような屋根材の下地を形成することが可能になっている。
Further, the roof plate 8 does not have to be a single plate from the purlin 7 to the girder 3, and may be composed of two plates such as a roof plate 8a and a roof plate 8b as shown in FIG. 5 (two plates). It does not matter if the number exceeds. In this case, the joint portion between the roof plate 8a and the roof plate 8b is supported by the purlin 6 attached to the mounting bracket 30, and both are fixed to the purlin 6.
With such a structure, the mounting bracket 30 that supports the roof plate 8a and the roof plate 8b also functions as a connecting means that connects the roof plate 8a and the roof plate 8b, and a long inclined surface can be formed by the plurality of roof plates. Even in the case of the construction, it is possible to form the base material of the roofing material as in the case of using the roofing board composed of one sheet.
