The upper part of the suspension bolt 21 is fixed by the upper and lower nuts 23 and 26 via the waterproof packing 25 and the mountain seat 24 (FIGS. 2A and 3A). reference). The eaves hanger 22 is made of a piece of metal or the like, and is connected to the hanger bolt 21 at its substantially central portion. The eaves hanger (corresponding to the left and right in the figure) (Not shown) are provided with ear-holding portions 22a and 22a for holding the front and rear ears.

一方、屋根吊り具用補強具１０は、上記屋根吊り具２０を補強するもので、特に吊りボルト２１に対して添え木のごとく取り付けられる。 On the other hand, the roof hanger reinforcing tool 10 reinforces the roof hanger 20, and is attached to the hanger bolt 21 like a splint.

すなわち、屋根吊り具用補強具１０は、図１に示すように、吊りボルト２１の添え木として作用する補強杆体１１と、この補強杆体１１を吊りボルト２１に連結固定するための上下一対の連結具Ｒ、Ｒとより構成されている。 That is, as shown in FIG. 1, the roof hanger reinforcing tool 10 includes a reinforcing housing 11 that acts as a splint of the hanging bolt 21 and a pair of upper and lower connecting tools for connecting and fixing the reinforcing housing 11 to the hanging bolt 21. R and R are comprised.

補強杆体１１は、金属材、硬質樹脂材等の硬質な材料よりなり、吊りボルト２１の全長または上部を強化するために、吊りボルト２１と略同等またはやや短めの長さに形成されており、また、より強固な補強体として作用させるために、主片１１ａと副片１１ｂよりなる横断面Ｌ字形の屈曲片に形成されている。また、主片１１ａの上下端にはボルト止めのためのボルト挿通孔１１ａａが開設されている。   The reinforcing housing 11 is made of a hard material such as a metal material or a hard resin material, and has a length substantially equal to or slightly shorter than the suspension bolt 21 in order to reinforce the entire length or upper portion of the suspension bolt 21. Moreover, in order to make it act as a stronger reinforcement body, it forms in the bending piece of the cross-sectional L-shape which consists of the main piece 11a and the subpiece 11b. In addition, bolt insertion holes 11aa for fastening bolts are formed at the upper and lower ends of the main piece 11a.

一方、上下の連結具Ｒ、Ｒはそれぞれ、金属材、硬質樹脂材等の硬質な材料よりなり、１枚の板材を折曲および湾曲させて２つの筒体を有した状態で重合して形成されている。以下では、２つの連結具Ｒ、Ｒを区別して説明する場合には、補強杆体１１の上端に固定する連結具Ｒを上連結具Ｒ１、補強杆体１１の下端に固定する連結具Ｒを下連結具Ｒ２という。   On the other hand, the upper and lower connectors R and R are each made of a hard material such as a metal material or a hard resin material, and are formed by bending and bending one plate material and having two cylinders. Has been. In the following, when the two connectors R, R are described separately, the connector R that fixes the upper end of the reinforcing housing 11 is connected to the upper connector R1 and the connector R that fixes the lower end of the reinforcing housing 11 is connected to the lower end. It is called ingredient R2.

連結具Ｒは、開閉自在なリング体１２ａを含んで構成された、吊りボルト２１を抱持するための抱持体１２と、その抱持体１２に連設された筒体よりなる屋根支持補助部１４とを備えている。抱持体１２の開閉部は補強杆体１１との固定部１２ｂを構成しており、固定部１２ｂの重なり合う２片にはボルト挿通孔１２ｂａが開設されている。また、固定部１２ｂの上端側には、固定部１２ｂを構成する２片の上端から相互に遠ざかる方向に折曲され横方向に延出した屋根支持片１３が形成されている。   The connector R includes a ring body 12a that can be freely opened and closed, and includes a holding body 12 for holding the suspension bolt 21 and a cylindrical body that is connected to the holding body 12. Part 14. The opening / closing part of the holding body 12 constitutes a fixing part 12b with the reinforcing casing 11, and bolt insertion holes 12ba are formed in two overlapping pieces of the fixing part 12b. A roof support piece 13 is formed on the upper end side of the fixed portion 12b. The roof support piece 13 is bent in the direction away from the upper ends of the two pieces constituting the fixed portion 12b and extends in the lateral direction.

すなわち、この屋根吊り具用補強具１０は、補強杆体１１を連結具Ｒで挟み込んでボルトＢ、ナットＮで固定した状態では、補強杆体１１の上下端に抱持体１２が連設され、補強杆体１１の上下端に屋根支持片１３が連設された形状となる（図２（ａ）参照）。 That is, the roof hanging tool reinforcing tool 10 includes a holding body 12 connected to the upper and lower ends of the reinforcing casing 11 in a state where the reinforcing casing 11 is sandwiched between the connecting tools R and fixed with bolts B and nuts N. It becomes the shape where the roof support piece 13 was continuously provided in the upper and lower ends of the housing 11 (refer Fig.2 (a)).

この屋根吊り具用補強具１０は、図２（ａ）、図３（ａ）に示すように、補強杆体１１に連結された上下の連結具Ｒ、Ｒの両抱持体１２、１２で吊りボルト２１を抱持し、上下に移動しないように固定することで、補強杆体１１が吊りボルト２１に平行な状態で固定される。 As shown in FIGS. 2 (a) and 3 (a), the roof hanging tool reinforcing tool 10 is hung by both holding bodies 12 and 12 of upper and lower connecting tools R and R connected to the reinforcing housing 11. By holding the bolt 21 and fixing it so as not to move up and down, the reinforcing housing 11 is fixed in a state parallel to the suspension bolt 21.

具体的には、屋根吊り具用補強具１０は、上連結具Ｒ１の上端と補強杆体１１の上端とが折板屋根３０の裏面に接触し、その上連結具Ｒ１と、折板屋根３０の上面側に配され、吊りボルト２１に螺合したナット２３、山座２４、防水パッキン２５との間に折板屋根３０を挟み込み、該ナット２３と、上連結具Ｒ１の下側に配したナット２６とで締め付けて、上連結具Ｒ１およびこれに連結された補強杆体１１が吊りボルト２１の上部に固定される取付構造となっている。なお、下連結具Ｒ２の下側でナット２６止めしてもよい。 Specifically, in the roof hanging tool reinforcing tool 10, the upper end of the upper connecting tool R <b> 1 and the upper end of the reinforcing frame 11 are in contact with the back surface of the folded plate roof 30, and the upper connecting tool R <b> 1 and the folded plate roof 30 A folded plate roof 30 is sandwiched between a nut 23, a mountain seat 24, and a waterproof packing 25, which are arranged on the upper surface side and screwed into the suspension bolt 21, and the nut 23 and a nut arranged on the lower side of the upper connector R1. 26, the upper connector R1 and the reinforcing housing 11 connected thereto are fixed to the upper portion of the suspension bolt 21. The nut 26 may be fixed on the lower side of the lower connector R2.

さらに具体的には、このように折板屋根３０に対して、屋根吊り具用補強具１０を屋根吊り具２０とともに取り付けたときには、少なくとも、上連結具Ｒ１の両端に設けた屋根支持片１３および屋根支持補助部１４の上面が折板屋根３０の裏面に接触して、安定して連結されることとなる（図２（ａ）、図３（ａ）参照）。なお、図例では補強杆体１１のＬ字形の上端面も折板屋根３０の裏面に接触している。 More specifically, when the roof hanger reinforcing tool 10 is attached to the folded plate roof 30 together with the roof hanger 20, in this way, at least the roof support pieces 13 provided at both ends of the upper connector R1 and The upper surface of the roof support auxiliary portion 14 comes into contact with the back surface of the folded plate roof 30 and is stably connected (see FIGS. 2A and 3A). In the illustrated example, the L-shaped upper end surface of the reinforcing housing 11 is also in contact with the back surface of the folded plate roof 30.

屋根吊り具用補強具１０の例としては、抱持体１２を構成するリング体１２ａのみが他よりわずかに低く形成された図２の例と、抱持体１２（のリング体１２ａ部分）、屋根支持片１３および屋根支持補助部１４の上面の各高さが同一である図３の例を挙げている。 As an example of the reinforcing tool 10 for the roof hanger, only the ring body 12a constituting the holding body 12 is formed slightly lower than the other, and the holding body 12 (the ring body 12a portion), The example of FIG. 3 with which the height of the upper surface of the roof support piece 13 and the roof support auxiliary | assistant part 14 is the same is given.

図２に示した屋根吊り具用補強具１０は、抱持体１２のリング体１２ａと折板屋根３０との間に挟みこむ支持補助体１５の高さ分、リング体１２ａを低くしてある。この支持補助体１５は薄板ドーナツ形状をなしており、従来、本屋根吊り具用補強具１０を使用せずに屋根吊り具２０を取り付ける場合に使用するワッシャを代用すればよい。また、図３に示した屋根吊り具用補強具１０は、抱持体１２のリング体１２ａ、屋根支持片１３および屋根支持補助部１４の全てが同一高さに形成されているため、それら全てが折板屋根３０の裏面に接触する。 In the roof suspension reinforcing tool 10 shown in FIG. 2, the ring body 12 a is lowered by the height of the support auxiliary body 15 sandwiched between the ring body 12 a of the holding body 12 and the folded roof 30. . The support auxiliary body 15 has a thin plate donut shape, and conventionally, a washer used when the roof hanging tool 20 is attached without using the present roof hanging tool reinforcement 10 may be substituted. In addition, the roof hanging tool reinforcing tool 10 shown in FIG. 3 has the ring body 12a, the roof support piece 13, and the roof support auxiliary portion 14 of the holding body 12 all formed at the same height. Contacts the back of the folded plate roof 30.

また、図２（ｂ）、図３（ｂ）には、屋根吊り具用補強具１０と折板屋根３０の裏面との接触状態を表した折板屋根３０の部分平面図を示している。 FIGS. 2B and 3B are partial plan views of the folded plate roof 30 showing a contact state between the roof-suspender reinforcing tool 10 and the back surface of the folded plate roof 30.

これらの図に示すように、折板屋根３０との連結部位（吊りボルト挿通孔３１とその周辺部位）に連なるように屋根支持片１３および屋根支持補助部１４が連設され、それらが折板屋根３０に対してより広い面積で接触しているので、吊りボルト２１の折板屋根３０に対する連結による負荷が分散され、連結部位への負担を軽減でき、折板屋根の連結部位の損傷を防止できる。また、屋根吊り具用補強具１０はより広い面積で折板屋根３０と接触しているので、ぐらつきを防止でき、設置が安定する。 As shown in these drawings, the roof support piece 13 and the roof support auxiliary portion 14 are continuously provided so as to be connected to a connection portion (the suspension bolt insertion hole 31 and its peripheral portion) with the folded plate roof 30, and these are folded plates. Since it is in contact with the roof 30 in a wider area, the load due to the connection of the suspension bolt 21 to the folded plate roof 30 is dispersed, the burden on the connected portion can be reduced, and damage to the connected portion of the folded plate roof is prevented. it can. Moreover, since the roof hanging tool reinforcement 10 is in contact with the folded plate roof 30 in a wider area, wobble can be prevented and the installation is stabilized.

このように、屋根吊り具用補強具１０は安定状態を維持できる取付構造であるため、添え木としての効果を十分に発揮できる。 Thus, since the roof hanging tool reinforcement 10 has a mounting structure capable of maintaining a stable state, the effect as a splint can be sufficiently exhibited.

以上のように、本屋根吊り具用補強具１０は、屋根吊り具２０を補強するものであるが、折板屋根３０との連結構造によって補強具自体も安定化、強化される。また、屋根吊り具用補強具１０を本実施形態のように長板状の補強杆体１１と、抱持体１２、１２を含んだ上下の連結具Ｒ、Ｒとより構成すれば、少ない材料で形成でき、コストの低減化も図れる。 As described above, the reinforcing tool 10 for the roof hanging tool reinforces the roof hanging tool 20, but the reinforcing tool itself is stabilized and strengthened by the connection structure with the folded plate roof 30. Moreover, if the roof hanging tool reinforcement 10 is composed of a long plate-like reinforcement housing 11 and upper and lower connecting tools R and R including the holding bodies 12 and 12 as in this embodiment, the amount of material can be reduced. It can be formed and the cost can be reduced.

ついで、本発明の第２実施形態および第３実施形態（参考例）について、図４、図５に示した分解斜視図および図６に示した使用状態図を参照しながら説明する。なお、図６には、図４の屋根吊り具用補強具１０（第２実施形態）に対応した折板屋根３０との連結状態を表した正面図を示している。図５の屋根吊り具用補強具１０に対応した使用状態については、図６とほぼ同様であるため図示を省略している。また、第２、第３実施形態では、第１実施形態と同様の構成については同一の符号を図４〜図６に付して、その説明を省略する。 Next, a second embodiment and a third embodiment (reference example) of the present invention will be described with reference to an exploded perspective view shown in FIGS. 4 and 5 and a use state diagram shown in FIG. FIG. 6 is a front view showing a connection state with the folded plate roof 30 corresponding to the roof suspension tool reinforcement 10 (second embodiment) of FIG. 4. Since the use state corresponding to the roof suspension tool reinforcement 10 in FIG. 5 is substantially the same as that in FIG. 6, the illustration is omitted.

It can be carried out without difficulty, and the attaching work to the suspension bolt 21 can be performed quickly. For example, when attaching the roof hanger reinforcing tool 10 to the existing hanger bolt 21, if the piece of the fixing portion 12 b of the holding body 12 is temporarily fixed to the reinforcing housing 11, the work can be easily performed. .

なお、これらの２実施形態では、図６に示すように、屋根支持片１３が高く形成されているので、リング状の支持補助体１５を折板屋根３０とリング体１２ａとの間に嵌め入れて高さが調節されている。これによって、屋根吊り具用補強具１０が安定状態を保持する。なお、屋根支持片１３と、リング体１２ａとの高さを同一にして安定させてもよい。 In these two embodiments, as shown in FIG. 6, since the roof support piece 13 is formed high, the ring-shaped support auxiliary body 15 is fitted between the folded plate roof 30 and the ring body 12a. The height is adjusted. Thereby, the reinforcing tool 10 for roof hanging tools maintains a stable state. In addition, you may stabilize by making the height of the roof support piece 13 and the ring body 12a the same.

また、第１実施形態では、下連結具Ｒ２にも屋根支持片１３を設けて上下の連結具Ｒを同形状に形成することで２つの連結具Ｒ、Ｒを上下いずれにも使用できるようにしているが、屋根支持片１３は折板屋根３０に対して必要なものであるため、上連結具Ｒ１だけに形成したものでもよい。一方、第２、第３実施形態では、補強杆体１１の上下に屋根支持片１３、１３を設けることで補強杆体１１を天地を逆にしても使用できるようにしているが、同様に上部だけに形成したものでもよい。   Further, in the first embodiment, the lower connecting tool R2 is also provided with the roof support piece 13 so that the upper and lower connecting tools R are formed in the same shape so that the two connecting tools R and R can be used both in the upper and lower directions. However, since the roof support piece 13 is necessary for the folded plate roof 30, it may be formed only on the upper connector R1. On the other hand, in the second and third embodiments, the roof support pieces 13 and 13 are provided above and below the reinforcing casing 11 so that the reinforcing casing 11 can be used even when the top and bottom are reversed. It may be formed.
