It is fixed to channel 11.
次に、折板屋根12を第1の屋根金物100に取り付ける手順について説明する。まず、吊子14の貫通孔にボルト176aが貫通するように、支持頂部175の頂面に吊子14が置かれる。そして、貫通孔から突出したボルト176aにナット及びワッシャ176bをねじ込み、締結する。これにより、吊子14が第1の屋根金物100に固定される。そして、上方から吊子14に嵌合式折板13をかぶせるように取り付け、さらにその上方からキャップ15をかぶせ、所定の圧力でキャップ15を嵌合式折板13を介して吊子14に押しつける。これにより、キャップ15が嵌合式折板13を挟んで吊子14と嵌合し、折板屋根12が第1の屋根金物100に取り付けられる。 Next, a procedure for attaching the folded plate roof 12 to the first roof hardware 100 will be described. First, the suspension 14 is placed on the top surface of the support top 175 so that the bolt 176 a penetrates the through hole of the suspension 14. Then, the nut and washer 176b are screwed into and fastened to the bolt 176a protruding from the through hole. Thereby, the suspension 14 is fixed to the first roof hardware 100. Then, the fitting type folding plate 13 is attached so as to cover the hanger 14 from above, the cap 15 is further covered from above, and the cap 15 is pressed against the hanger 14 via the fitting type folding plate 13 with a predetermined pressure. As a result, the cap 15 is fitted to the hanger 14 with the fitting-type folding plate 13 interposed therebetween, and the folding plate roof 12 is attached to the first roof hardware 100.
一般に、風が強い地域に立てられる建築物あるいは壁がない建築物に用いられる折板屋根には、折板屋根を梁材から引きはがすような力が加わる。そのため、このような建築物に用いられる屋根金物には、大きな力に耐えうることが求められる。本実施形態による第1の屋根金物100は、C型チャンネル11に取り付けられた状態において、第1の上側固定部材110と第1の下側固定部材140とが、C型チャンネル11を全周に渡って保持する。そのため、折板屋根12をC型チャンネル11から引きはがすような力が加わっても、第1の端部141と第1の突出部117とが密着し、かつボルト151aとダブルナット151bとによって密着固定されること、及び第2の端部142と第2の突出部118とが密着し、かつボルト152aとダブルナット152bとによって密着固定されることにより、第1の上側固定部材110と第1の下側固定部材140とが分離しにくくなって、大きな力に耐えることができる。また、第1の折曲部111及び第2の折曲部112が第1の底部113から上方に突出するため、第1の上側固定部材110は、X軸回りのモーメント力に対して抵抗可能であって、これによりX軸回りに曲げられにくくなる。 In general, a folded plate roof used for a building standing in a windy area or a building without walls is subjected to a force of peeling the folded plate roof from a beam member. Therefore, roof metal fittings used for such buildings are required to withstand a large force. In the first roof metal fitting 100 according to the present embodiment, the first upper fixing member 110 and the first lower fixing member 140 are attached to the C-shaped channel 11 so that the C-shaped channel 11 is surrounded by the first upper fixing member 110 and the first lower fixing member 140. Hold across. Therefore, even if a force for peeling the folded-plate roof 12 from the C-shaped channel 11 is applied, the first end 141 and the first protrusion 117 are in close contact with each other, and the bolt 151a and the double nut 151b are in close contact with each other. The first upper fixing member 110 and the first upper fixing member 110 are fixed by being fixed, and the second end portion 142 and the second projecting portion 118 are in close contact with each other and the bolt 152a and the double nut 152b are in close contact with each other. It becomes difficult to separate the lower fixing member 140 from the lower fixing member 140, and a large force can be endured. Moreover, since the first bent portion 111 and the second bent portion 112 project upward from the first bottom portion 113, the first upper fixing member 110 can resist the moment force about the X axis. Therefore, it becomes difficult to bend around the X axis.
なお、第1の屋根金物100が取り付けられる梁材はC型チャンネル11に限定されず、アングル材やその他、梁材として使用可能な鋼材であってもよい。この場合、第1の下側固定部材140の形状は、梁材の形状に応じて適宜変更されうる。また、第1の屋根金物100に取り付けられる折板は嵌合式折板に限定されず、ハゼ式折板、重ね式折板、又はその他の折板式屋根であってもよい。この場合、第1の折板支持部170の形状は、折板の取り付け手段に応じて適宜変更されうる。 The beam member to which the first roof metal fitting 100 is attached is not limited to the C-shaped channel 11 and may be an angle member or other steel members usable as the beam member. In this case, the shape of the first lower fixing member 140 can be appropriately changed according to the shape of the beam member. Further, the folding plate attached to the first roof metal fitting 100 is not limited to the fitting type folding plate, and may be a goby type folding plate, a stacking type folding plate, or another folding plate type roof. In this case, the shape of the first folded plate supporting portion 170 can be appropriately changed depending on the attachment means of the folded plate.
また、第1の上側固定部材110と第1の折板支持部170とは溶接以外の手段、例えば接着剤やボルト・ナット等によって接続されてもよい。ボルト176aは第1の折板支持部170に溶接されなくてもよい。 Further, the first upper fixing member 110 and the first folded plate supporting portion 170 may be connected by means other than welding, for example, an adhesive agent, a bolt/nut or the like. The bolt 176a may not be welded to the first folded plate support portion 170.

比較例
図7及び8に示す通り、特開2010−90672号公報に記載の外装用取付部材と同様の屋根金物401を比較例とした。屋根金物401は、折板屋根を支持するとともに、C型チャンネル11上に着地部422をC型チャンネル11上に着地させる本体402と、着地部422上に重ねて一端縁をC型チャンネル11の外側へ延在させた上側固定具403と、C型チャンネル11を下方から包持して一端縁をC型チャンネル11の外側へ延在させた下側固定具404とを備える。上側固定具403及び下側固定具404の他端は折り曲げられて、C型チャンネル11の開口又は角に引っかけられる。そして、上側固定具403と下側固定具404との各一端縁をボルト405にて締め付けることにより、着地部422がC型チャンネル11に押し当てられ、これにより屋根金物401がC型チャンネル11に取り付けられる。本体402の頂面から上方に向けてボルト403が延びる。試験機に固定されたC型チャンネルに屋根金物401を取り付け、屋根金物401から延びるボルト406を鉛直上方に引っ張った。屋根金物401を構成する各部材は、厚さ4.5mmのSPHC(熱間圧延鋼板)にドブメッキを施して形成される。なお、図7及び8に示される屋根金物401の寸法の単位はミリメートルである。屋根金物401について引張試験を行った結果を図10及び表1に示した。表1には、2体の試験体のうち、安全を見込んで最大荷重が低い方を選択し、記載した。図10には、2体の試験体のうち、一方を比較例1、他方を比較2として記載した。比較例1と比較例2の材料及び寸法は同じである。なお、図10において、図9と同様に、説明の容易のため、比較例2に係る曲線を比較例1に係る曲線よりもグラフ上においてストローク8mm相当だけずらして示した。
Comparative Example As shown in FIGS. 7 and 8, a roof metal fitting 401 similar to the exterior mounting member described in JP 2010-90672 A was used as a comparative example. The roof metal fitting 401 supports a folded-plate roof and also has a main body 402 that lands the landing portion 422 on the C-shaped channel 11 and the main body 402 that lands on the landing portion 422 and has one end edge of the C-shaped channel 11. An upper fixing tool 403 extending outward and a lower fixing tool 404 wrapping the C-shaped channel 11 from below and extending one end edge to the outside of the C-shaped channel 11 are provided. The other ends of the upper fixing tool 403 and the lower fixing tool 404 are bent and hooked on the opening or corner of the C-shaped channel 11. Then, by tightening one end edges of the upper fixture 403 and the lower fixture 404 with bolts 405, the landing portion 422 is pressed against the C-shaped channel 11, whereby the roof metal fitting 401 is attached to the C-shaped channel 11. It is attached. A bolt 403 extends upward from the top surface of the main body 402. A roof metal fitting 401 was attached to a C-shaped channel fixed to a tester, and a bolt 406 extending from the roof metal fitting 401 was pulled vertically upward. Each member that constitutes the roof metal fitting 401 is formed by performing dobb plating on SPHC (hot rolled steel plate) having a thickness of 4.5 mm. The unit of the dimensions of the roof metal fitting 401 shown in FIGS. 7 and 8 is millimeter. The results of the tensile test performed on the roof metal fitting 401 are shown in FIG. 10 and Table 1. In Table 1, out of the two test bodies, the one with the lowest maximum load was selected for safety and described. In FIG. 10, one of the two test bodies is shown as Comparative Example 1 and the other is shown as Comparative 2. The materials and dimensions of Comparative Example 1 and Comparative Example 2 are the same. Note that, in FIG. 10, similarly to FIG. 9, the curve according to Comparative Example 2 is shown shifted from the curve according to Comparative Example 1 by a stroke equivalent to 8 mm for easy description.
実施例は、比較例と比較して、許容荷重が約2.8倍となった。 In the example, the allowable load was about 2.8 times that of the comparative example.
本実施形態によれば、比較例と比較して、有意に強度が高い屋根金物を得ることができる。すなわち、本実施形態による屋根金物は、より多くの風荷重に耐えることができる。 According to the present embodiment, it is possible to obtain a roof metal fitting having significantly higher strength than that of the comparative example. That is, the roof hardware according to the present embodiment can withstand a larger wind load.
なお、いずれの実施形態においても、第1〜3の屋根金物100〜300が取り付けられる梁材は、C型チャンネル、アングル材、その他の梁材として使用可能な鋼材であってもよい。例えば屋根金物をC型チャンネルに取り付ける場合、下側固定部材として第1の下側固定部材140を用いてもよく、例えば屋根金物をアングル材に取り付ける場合、下側固定部材として第2の下側固定部材240を用いてもよい。 In any of the embodiments, the beam member to which the first to third roof metal fittings 100 to 300 are attached may be a C-shaped channel, an angle member, or any other steel member that can be used as a beam member. For example, when attaching the roof metal fittings to the C-shaped channel, the first lower fixing member 140 may be used as the lower fixing member. For example, when attaching the roof metal fittings to the angle member, the second lower fixing member is used as the lower fixing member. The fixing member 240 may be used.
また、屋根金物に取り付けられる折板は、嵌合式折板、ハゼ式折板、重ね式折板、又はその他の折板式屋根であってもよい。例えば屋根金物をC型チャンネルに取り付ける場合、折板支持部として第1の折板支持部170を用いてもよく、例えば屋根金物をハゼ式折板に取り付ける場合、折板支持部として第2の折板支持部270が用いられてもよく、例えば屋根金物を重ね式折板に取り付ける場合、折板支持部として第3の折板支持部370が用いられてもよい。 Further, the folding plate attached to the roof metal fitting may be a fitting type folding plate, a goby type folding plate, a stacking type folding plate, or another folding plate type roof. For example, when attaching the roof metal fittings to the C-shaped channel, the first folded plate support portion 170 may be used as the folded plate support portion. For example, when attaching the roof metal fittings to the goby-type folded plate, the second folded plate support portion may be used. The folded plate support portion 270 may be used. For example, when the roof metal fitting is attached to the stacking folded plate, the third folded plate support portion 370 may be used as the folded plate support portion.
第1の下側固定部材140及び第2の下側固定部材240の代わりに、丸棒を折り曲げて形成された部材を下側固定部材として用いてもよい。この場合、丸棒の両端部に雄ねじが切られて上側固定部材のボルト孔に貫通され、ナットを用いて上側固定部材に固定される。 Instead of the first lower fixing member 140 and the second lower fixing member 240, a member formed by bending a round bar may be used as the lower fixing member. In this case, male screws are cut at both ends of the round bar to pass through the bolt holes of the upper fixing member and are fixed to the upper fixing member using nuts.
