Description

本発明は、二重折板屋根などの折板屋根を形成する際に用いられる屋根材取付具に関するものである。 The present invention relates to a roofing material fixture used when forming a folded plate roof such as a double folded plate roof.

金属製の屋根材である折板屋根材は外気温や太陽光等の熱により伸縮するため、これにより、ストレスや摩擦力が折板屋根材に蓄積されて折板屋根材が大きくうねり、バックリングと呼ばれる爆烈音を発生させることがある。そこで、このような折板屋根材の熱伸縮による爆裂音の発生を防止するために各種の提案がなされている。 Folded plate roofing material, which is a metal roofing material, expands and contracts due to outside air temperature and heat from sunlight, etc., which causes stress and frictional forces to accumulate in the folded plate roofing material, causing the folded plate roofing material to swell and back. It may generate an explosive sound called a ring. Therefore, various proposals have been made to prevent the generation of explosive sound due to thermal expansion and contraction of such a folded plate roof material.

例えば、特許文献１には金属屋根の支持構造が記載されている。この金属屋根は二重折板屋根であって、図１１に示すように、上弦折板である上側屋根材３０と下弦折板である下側屋根材３１とを対向配置して形成されている。下側屋根材３１は母屋等に固定されたタイトフレーム４１に固定吊子４８を介して連結固定されている。また、上側屋根材３０は複数個の屋根材取付具Ａを介して下側屋根材３１に連結固定されている。 For example, Patent Document 1 describes a support structure for a metal roof. This metal roof is a double folded plate roof, and as shown in FIG. 11, the upper roof material 30 which is an upper chord folded plate and the lower roof material 31 which is a lower chord folded plate are arranged to face each other. . The lower roof material 31 is connected and fixed to a tight frame 41 fixed to a purlin or the like via a fixed suspension 48. Further, the upper roof material 30 is connected and fixed to the lower roof material 31 via a plurality of roof material attachments A.

この屋根材取付具Ａは受け部材１と可動吊子２とを備えて形成されている。受け部材１には前後方向に長いガイド溝２４が形成されており、このガイド溝２４に可動吊子２をスライド移動自在に取り付けている。そして、受け部材１を下側屋根材３１の馳締め部４７に係止して取り付けると共に可動吊子２の上端に設けた係止部１９を上側屋根材３０の馳締め部４７に係止して取り付けるようにしている。 This roofing material fixture A is formed with a receiving member 1 and a movable hanging member 2. The receiving member 1 is formed with a guide groove 24 that is long in the front-rear direction, and the movable suspension 2 is slidably attached to the guide groove 24. The receiving member 1 is locked and attached to the tightening portion 47 of the lower roof material 31 and the locking portion 19 provided at the upper end of the movable hanging member 2 is locked to the tightening portion 47 of the upper roof material 30. To be installed.

このような金属屋根では、可動吊子２がガイド溝２４の長手方向に沿って屋根の傾斜方向と平行にスライド移動することにより、上側屋根材３０が熱伸縮可能となり、ストレスや摩擦力が上側屋根材３０に蓄積されないようにして、爆裂音等の発生を防ぐことができるものである。
特許第３０６５９４０号公報 In such a metal roof, the movable roof 2 is slid along the longitudinal direction of the guide groove 24 in parallel with the inclination direction of the roof, so that the upper roof material 30 can be thermally expanded and contracted, and stress and frictional force are increased on the upper side. Generation | occurrence | production of an explosion sound etc. can be prevented by making it not accumulate | store in the roofing material 30. FIG.
Japanese Patent No. 3065940

しかし、上記の従来例では、母屋に不陸があった場合や施工の不備などが原因でタイトフレーム４１が所定位置から位置ずれして取り付けられた場合に、下側屋根材３１に歪みが生じ、この歪みにより、複数個の屋根材取付具Ａの互いの位置関係が設計通りにならなかったり、上側屋根材３０が設計通りの位置に取り付けられないことがあった。このため、受け部材１と可動吊子２とが互いに上下左右のいずれかに片寄った状態で連結されてガイド溝２４と可動吊子２の移動方向とが平行とならず、受け部材１と可動吊子２との間に大きな摩擦力が生じるおそれがあった。そして、この場合、上側屋根材３０が熱伸縮すると、可動吊子２のスライド移動に大きな応力がかかり、爆裂音の発生を充分に低減できないことがあった。 However, in the above-described conventional example, when the main frame is uneven or when the tight frame 41 is displaced from a predetermined position due to inadequate construction, the lower roof material 31 is distorted. Due to this distortion, the positional relationship between the plurality of roofing material attachments A may not be as designed, or the upper roofing material 30 may not be attached at the designed position. For this reason, the receiving member 1 and the movable suspension 2 are connected in a state where they are offset from each other in the vertical and horizontal directions, so that the guide groove 24 and the moving direction of the movable suspension 2 are not parallel to each other. There was a possibility that a large frictional force would be generated between the suspension 2 and the suspension 2. In this case, when the upper roof material 30 is thermally expanded and contracted, a large stress is applied to the sliding movement of the movable hanging member 2, and the generation of the explosion sound may not be sufficiently reduced.

本発明は上記の点に鑑みてなされたものであり、爆裂音の発生を充分に低減することができる屋根材取付具を提供することを目的とするものである。 This invention is made | formed in view of said point, and it aims at providing the roofing material fixture which can fully reduce generation | occurrence | production of an explosion sound.

以下、本発明を実施するための最良の形態を説明する。 Hereinafter, the best mode for carrying out the present invention will be described.

図１（ａ）に、本発明の可動吊子２を備えた屋根材取付具Ａを示す。この屋根材取付具Ａは、上側屋根材３０と下側屋根材３１との間を断熱空間３２とする断熱性の高い断熱屋根を形成する際に、上側屋根材３０と下側屋根材３１とを離間させた状態で連結するために用いられるものである。このような断熱屋根としては二重折板屋根を例示することができ、この場合、上側屋根材３０と下側屋根材３１としては塗装鋼板や亜鉛めっき鋼板などの金属板をロール成形などで折り曲げて形成した折板屋根材４９を用いることができる。このような屋根材取付具Ａは、受け部材１、可動吊子２、断熱部材３を備えて形成することができる。受け部材１はこの実施の形態において屋根材保持具６９として形成されているものである。 Fig. 1 (a) shows a roofing material fixture A provided with the movable hanging piece 2 of the present invention. When this roofing material attachment A forms a heat-insulating roof having a high thermal insulation property between the upper roofing material 30 and the lower roofing material 31, the upper roofing material 30, the lower roofing material 31, Are used for connection in a state of being separated. An example of such a heat insulating roof is a double folded plate roof. In this case, as the upper roof material 30 and the lower roof material 31, a metal plate such as a coated steel plate or a galvanized steel plate is bent by roll forming or the like. The folded-plate roof material 49 formed in this way can be used. Such a roofing material fixture A can be formed including the receiving member 1, the movable hanging member 2, and the heat insulating member 3. The receiving member 1 is formed as a roofing material holder 69 in this embodiment.

図２（ａ）に示すように、本発明の可動吊子２は、吊子本体７０と連結部材７３とを備えて形成されている。吊子本体７０は溶融亜鉛めっき鋼板や塗装鋼板やステンレス鋼板等の金属板を折り曲げ加工して形成されるものであり、例えば、厚み０．６〜１．８ｍｍの金属板を用いることができる。図２（ｂ）に示すように、吊子本体７０は、矩形板状の連結部７７と、連結部７７の下端部から側方に向かって略水平に突出する挿入部７８と、連結部７７の上端部から側方（挿入部７８と反対側）に向かって略水平に突出する突出部１８と、突出部１８の先端から連結部７７側に向かって斜め下方に突出する係止部１９とを設けて形成されている。この連結部７７と挿入部７８と突出部１８により、可動吊子２を屋根材保持具６９と連結するための立ち上がり部７２を形成することができる。また、挿入部７８の略中央部の一部を突出部１８側に突出するように折り返して結合片７８ａを形成している。 As shown in FIG. 2A, the movable hanging element 2 according to the present invention includes a hanging body 70 and a connecting member 73. The hanging body 70 is formed by bending a metal plate such as a hot-dip galvanized steel plate, a coated steel plate, or a stainless steel plate. For example, a metal plate having a thickness of 0.6 to 1.8 mm can be used. As shown in FIG. 2B, the hanging body 70 includes a rectangular plate-shaped connecting portion 77, an insertion portion 78 that protrudes substantially horizontally from the lower end portion of the connecting portion 77, and a connecting portion 77. A projecting portion 18 that projects substantially horizontally from the upper end of the projection toward the side (opposite to the insertion portion 78), and a locking portion 19 that projects obliquely downward from the tip of the projecting portion 18 toward the connecting portion 77. Is formed. The connecting portion 77, the insertion portion 78, and the protruding portion 18 can form a rising portion 72 for connecting the movable hanging element 2 to the roof material holder 69. Further, a coupling piece 78a is formed by folding back a part of a substantially central portion of the insertion portion 78 so as to protrude toward the protruding portion 18.

連結部材７３は溶融亜鉛めっき鋼板や塗装鋼板やステンレス鋼板等の金属板を折り曲げ加工して形成されるものであり、例えば、厚み０．６〜１．８ｍｍの金属板を用いることができる。また、連結部材７３は矩形板状に形成される底部７６と、底部７６の両方の長手端部から表面側に向かって折り返し屈曲して形成される一対の装着部１７、１７と、各装着部１７の先端から上方に向かって略垂直に突出する一対の挟着部１６、１６と、底部７６の両方の短辺端部から略水平に突出する一対の脱落防止部２１、２１とを備えて形成されている。 The connecting member 73 is formed by bending a metal plate such as a hot dip galvanized steel plate, a coated steel plate, or a stainless steel plate. For example, a metal plate having a thickness of 0.6 to 1.8 mm can be used. The connecting member 73 includes a bottom portion 76 formed in a rectangular plate shape, a pair of mounting portions 17 and 17 formed by bending back from the longitudinal end portions of both the bottom portions 76 toward the surface side, and each mounting portion. A pair of sandwiching portions 16 and 16 projecting substantially vertically from the tip of 17 and a pair of drop-off preventing portions 21 and 21 projecting substantially horizontally from both short side end portions of the bottom portion 76. Is formed.

そして、この実施の形態の可動吊子２は、上記の吊子本体７０と連結部材７３を接合して一体化することによって形成されている。吊子本体７０と連結部材７３とを接合するにあたっては、吊子本体７０の挿入部７８を連結部材７３の底部７６と一方の装着部１７との間に差し込んで配置すると共に結合片７８ａを底部７６と他方の装着部１７との間に差し込んで配置し、この吊子本体７０の連結部７７を連結部材７３の一対の挟着部１６、１６の間に配置し、この後、連結部７７と一対の挟着部１６、１６とをかしめなどにより接合する。尚、かしめの代わりに、溶接により接合しても良い。符号２０は、かしめにより形成される突起部である。このようにして上記の吊子本体７０と連結部材７３とを接合して一体化することによって、可動吊子２を形成することができる。 And the movable hanging element 2 of this embodiment is formed by joining and integrating the above-described hanging element main body 70 and the connecting member 73. In joining the hanging body 70 and the connecting member 73, the insertion portion 78 of the hanging body 70 is inserted between the bottom portion 76 of the connecting member 73 and the one mounting portion 17, and the coupling piece 78a is placed at the bottom portion. The connecting portion 77 of the hanging body 70 is disposed between the pair of sandwiching portions 16 and 16 of the connecting member 73, and thereafter the connecting portion 77. And the pair of sandwiching portions 16, 16 are joined by caulking or the like. In addition, you may join by welding instead of caulking. Reference numeral 20 denotes a protrusion formed by caulking. Thus, the movable suspension 2 can be formed by joining and integrating the above-described suspension body 70 and the connecting member 73.

図３（ａ）（ｂ）に示すように、受け部材１は一対のサドル半体１０、１０をボルトなどの結合具１１で結合して形成されるものである。サドル半体１０はステンレス鋼板やめっき鋼板や塗装鋼板などの金属板を折り曲げ加工して形成されるものであり、矩形板状の支持片１２の上端に断面略半円弧状の保持部１３を設けると共に支持板１２の下端に載置片１４を設けて形成されている。支持板１２にはネジ孔４４が形成されている。保持部１３と載置片１４とは共に支持板１２の一方の表面よりも外側に突出している。また、一対のサドル半体１０、１０のうちの一方には馳締め係合部１５が設けられている。馳締め係合部１５は支持片１２の下部に断面略つ字状に折り曲げ形成されており、保持部１３や載置片１４と同じ方向で支持板１２の表面に突出して形成されている。 As shown in FIGS. 3A and 3B, the receiving member 1 is formed by connecting a pair of saddle halves 10 and 10 with a connecting tool 11 such as a bolt. The saddle half 10 is formed by bending a metal plate such as a stainless steel plate, a plated steel plate, or a coated steel plate, and a holding portion 13 having a substantially semicircular cross section is provided at the upper end of a rectangular plate-like support piece 12. A mounting piece 14 is provided at the lower end of the support plate 12. A screw hole 44 is formed in the support plate 12. Both the holding portion 13 and the mounting piece 14 protrude outward from one surface of the support plate 12. Further, one of the pair of saddle halves 10 and 10 is provided with a tightening engagement portion 15. The clamping engagement portion 15 is formed to be bent in a substantially square cross section at the lower portion of the support piece 12 and is formed to protrude from the surface of the support plate 12 in the same direction as the holding portion 13 and the mounting piece 14.

断熱部材３は受け部材１や可動吊子２よりも熱が伝わりにくい非伝熱性を有するものであり、例えば、ＡＢＳ樹脂などのプラスチックの成形品で形成することができる。この断熱部材３は外形が略小判状の被保持部２２と、被保持部２２の上面にその長手方向の全長にわたって突設された一対のガイド片２３、２３とを備えて形成されている。また、被保持部２２にはその長手方向の両端面に開口するガイド溝２４が形成されており、このガイド溝２４は被保持部２２の上面開口を通じて一対のガイド片２３、２３の間の空間にまで至るように形成されている。 The heat insulating member 3 has a non-heat transfer property in which heat is less likely to be transferred than the receiving member 1 and the movable hanging member 2, and can be formed of a molded product of plastic such as ABS resin. The heat insulating member 3 includes a held portion 22 whose outer shape is substantially oval, and a pair of guide pieces 23 and 23 projecting from the upper surface of the held portion 22 over the entire length in the longitudinal direction. The held portion 22 is formed with guide grooves 24 that are open on both end faces in the longitudinal direction. The guide groove 24 is a space between the pair of guide pieces 23, 23 through the upper surface opening of the held portion 22. It is formed to reach to.

そして、図４に示すように、ガイド溝２４に臨む面、すなわち、被保持部２２の底面などの内面や一対のガイド片２３、２３の互いに対向する面は粗面８として形成されている。この粗面８は多数の微細な突起を設けて形成されている。このような多数の微細な突起を有する断熱部材３は微細な骨材入り樹脂で成形することにより形成することができる。骨材としては、無機系骨材としてガラスやセラミックや炭素等を素材とする繊維やビーズを用いることができ、有機系骨材としてはメラミンやアクリルなどの樹脂を素材とする繊維やビーズを用いることができる。繊維の骨材であれば、例えば、長さを３０〜１００μｍで直径１０〜３０μｍとすることができる。ビーズの骨材であれば、例えば、粒径が５０〜２００μｍとすることができる。樹脂としてＡＢＳ樹脂などを用いることができる。骨材の配合量は樹脂全量に対して質量比で１０〜３０％とするのが好ましい。１０％より少ないと骨材が少なすぎて骨材による粗面化や補強効果が小さくなるおそれがあり、３０％よりも多いと骨材が多すぎて成形性が低下するおそれがある。このように断熱部材３に含有（内蔵）した骨材は粗面８に露出したりして多数の微細な突起を形成することになり、これにより、粗面８はざらざらしている。 As shown in FIG. 4, the surface facing the guide groove 24, that is, the inner surface such as the bottom surface of the held portion 22 and the surfaces of the pair of guide pieces 23, 23 facing each other are formed as a rough surface 8. The rough surface 8 is formed with a large number of fine protrusions. The heat insulating member 3 having such a large number of fine protrusions can be formed by molding with a fine aggregate-containing resin. As aggregates, fibers and beads made of glass, ceramic, carbon, etc. can be used as inorganic aggregates, and fibers and beads made of resins such as melamine and acrylic are used as organic aggregates. be able to. In the case of a fiber aggregate, for example, the length may be 30 to 100 μm and the diameter may be 10 to 30 μm. In the case of an aggregate of beads, for example, the particle diameter can be 50 to 200 μm. An ABS resin or the like can be used as the resin. The blending amount of the aggregate is preferably 10 to 30% by mass ratio with respect to the total amount of the resin. If it is less than 10%, the aggregate is too small and the roughening or reinforcing effect by the aggregate may be reduced, and if it exceeds 30%, the aggregate is too much and the moldability may be reduced. As described above, the aggregate contained (incorporated) in the heat insulating member 3 is exposed to the rough surface 8 to form a large number of fine protrusions, and thus the rough surface 8 is rough.

そして、屋根材取付具Ａは次のようにして形成することができる。受け部材１は対向配置した一対のサドル半体１０、１０を結合具１１で結合して形成するものである。このとき、一対のサドル半体１０、１０は支持板１２、１２の内面（保持部１３や載置片１４が突出する面と反対側の面）同士を合わせるようにし、ネジ孔４４に結合具１１を螺着することにより結合することができる。また、上記のように結合したサドル半体１０、１０の間には断熱部材３を挟持して保持する。このとき、サドル半体１０の保持部１３の内側に断熱部材３の被保持部２２を嵌め込むようにし、対向するサドル半体１０、１０の保持部１３、１３の間に被保持部２２を介在させるようにする。従って、対向する保持部１３、１３の上端間には断熱部材３のガイド片２３、２３が介在するものである。 And the roofing fixture A can be formed as follows. The receiving member 1 is formed by connecting a pair of saddle halves 10 and 10 facing each other with a coupler 11. At this time, the pair of saddle halves 10 and 10 are arranged so that the inner surfaces of the support plates 12 and 12 (the surfaces opposite to the surfaces from which the holding portions 13 and the mounting pieces 14 protrude) are aligned with each other. 11 can be connected by screwing. Further, the heat insulating member 3 is sandwiched and held between the saddle halves 10 and 10 coupled as described above. At this time, the held portion 22 of the heat insulating member 3 is fitted inside the holding portion 13 of the saddle half 10, and the held portion 22 is interposed between the holding portions 13 and 13 of the opposing saddle halves 10 and 10. Intervene. Therefore, the guide pieces 23 and 23 of the heat insulating member 3 are interposed between the upper ends of the opposing holding portions 13 and 13.

上記のようにして受け部材１と断熱部材３とを一体化した後、この断熱部材３に可動吊子２を取り付ける。このとき、図１（ａ）に示すように、可動吊子２の底部７６及び装着部１７の部分を被保持部２２に形成されたガイド溝２４に差し込むと共に可動吊子２の挟着部１６の部分をガイド溝２４のガイド片２３、２３の間に位置させるようにするものであり、これにより、可動吊子２をスライド吊子として受け部材１及び断熱部材３に対して長手方向にスライド移動自在に取り付けることができる。また、ガイド溝２４に底部７６及び装着部１７を差し込んだ状態で脱落防止片２１を下方に向かって折り曲げる。これにより、脱落防止片２１がガイド溝２４の開口縁部に引っ掛かるようになって、底部７６及び装着部１７の部分をガイド溝２４から抜けないようにすることができ、受け部材１及び断熱部材３からの可動吊子２の脱落を防止することができる。また、受け部材１と可動吊子２との間のヒートブリッジを樹脂製の断熱部材３で防止することができる。 After the receiving member 1 and the heat insulating member 3 are integrated as described above, the movable suspension 2 is attached to the heat insulating member 3. At this time, as shown in FIG. 1A, the bottom 76 and the mounting portion 17 of the movable suspension 2 are inserted into the guide groove 24 formed in the held portion 22 and the sandwiching portion 16 of the movable suspension 2. Is positioned between the guide pieces 23, 23 of the guide groove 24, whereby the movable suspension 2 is slid in the longitudinal direction with respect to the receiving member 1 and the heat insulating member 3 as a slide suspension. Can be attached movably. Further, the drop-off prevention piece 21 is bent downward while the bottom 76 and the mounting portion 17 are inserted into the guide groove 24. As a result, the drop-off prevention piece 21 can be caught on the opening edge of the guide groove 24, so that the bottom 76 and the mounting portion 17 can be prevented from being removed from the guide groove 24. It is possible to prevent the movable hanging piece 2 from falling off from 3. Moreover, the heat bridge between the receiving member 1 and the movable suspension 2 can be prevented by the heat insulating member 3 made of resin.

そして、本発明の屋根材取付具Ａは、図１（ｂ）に示すように、ガイド溝２４に臨む面である被保持部２２の底面やガイド片２３、２３の互いに対向する面を粗面８として形成し、この粗面８と接触する可動吊子２の底部７６の下面や連結部材７３の挟着片１６の表面を金属の平滑面９として形成しているので、骨材により粗面８に形成された微細な多数の突起を平滑面９に点接触あるいは線接触させることができるものであり、これにより、粗面８がない場合に比べて、断熱部材３のガイド溝２４に臨む面と可動吊子２の表面との接触面積を少なくして摩擦を小さくすることができるものである。もちろん、ガイド溝２４による可動吊子２のスライド移動のガイドは損なわないようにすることができる。また、粗面８に骨材を含有させることにより粗面８の耐摩耗性が向上し、長期使用によっても可動吊子２のスライド性能を低下させないようにすることができるものである。 And the roofing material fixture A of this invention is rough as shown in FIG.1 (b) in the bottom face of the to-be-held part 22 which is a surface which faces the guide groove 24, and the mutually opposing surface of the guide pieces 23 and 23. As shown in FIG. 8, the lower surface of the bottom 76 of the movable hanging element 2 that contacts the rough surface 8 and the surface of the sandwiching piece 16 of the connecting member 73 are formed as a smooth metal surface 9. A number of fine protrusions formed on the surface 8 can be brought into point contact or line contact with the smooth surface 9, thereby facing the guide groove 24 of the heat insulating member 3 as compared with the case without the rough surface 8. The contact area between the surface and the surface of the movable suspension 2 can be reduced to reduce the friction. Of course, the guide of the sliding movement of the movable suspension 2 by the guide groove 24 can be kept intact. Further, by incorporating aggregate into the rough surface 8, the wear resistance of the rough surface 8 is improved, and the sliding performance of the movable suspension 2 can be prevented from being deteriorated even after long-term use.

ここで、可動吊子２のスライド移動実験の結果を示す。受け部材１と可動吊子２とを図１（ａ）（ｂ）に示すようにセットし、可動吊子２の上に折板の自重相当の錘（１４ｋｇ）を載せ、この状態で可動吊子２を水平方向に引張り、その時の抵抗値（引っ張り力）を測定した。断熱部材３として、ガラス繊維強化ＡＢＳ樹脂の成型品（繊維長約５０μｍ、繊維径約２０μｍのガラス繊維３０質量％含有）を用いた場合（実施例）と、ガラス繊維やその他の骨材を含有しないＡＢＳ樹脂の成型品を用いた場合（比較例）とで実験をした。その結果、実施例が三回の測定で３７Ｎ、４１Ｎ、４４Ｎの抵抗値を示し、平均４０Ｎになったのに対して、比較例では二回の測定で５１Ｎ、５５Ｎの抵抗値を示し、平均５３Ｎになった。このように本発明の屋根材取付具Ａは従来のものに比べて、約２５％の滑り抵抗を低減することができるものである。 Here, the result of the slide movement experiment of the movable suspension 2 is shown. The receiving member 1 and the movable suspension 2 are set as shown in FIGS. 1A and 1B, and a weight (14 kg) corresponding to the weight of the folded plate is placed on the movable suspension 2, and the movable suspension is placed in this state. The child 2 was pulled in the horizontal direction, and the resistance value (tensile force) at that time was measured. When the heat insulation member 3 is a molded product of glass fiber reinforced ABS resin (containing a fiber length of about 50 μm and a fiber diameter of about 20 μm containing 30% by mass of glass fiber) (Example), it contains glass fibers and other aggregates. An experiment was performed in the case of using a molded product of ABS resin (comparative example). As a result, the example showed resistance values of 37N, 41N, and 44N in three measurements and averaged 40N, while the comparative example showed resistance values of 51N and 55N in two measurements. 53N. Thus, the roof material fixture A of the present invention can reduce the slip resistance by about 25% compared to the conventional one.

The friction between 2 and the receiving member 1 can be reduced.

上記のように本発明は、突起２５を備えることにより、従来のように突起２５がない構造に比べて、受け部材１と可動吊子２との摩擦を小さくして移動性を向上させることができ、母屋等の建物構造材のひずみや施工のばらつきなどを吸収して可動吊子２をスムーズにスライド移動させることができるものである。また、受け部材１と可動吊子２との摩擦を小さくするために、潤滑油を塗布する手法も考えられているが、メンテナンス性が低く、熱等により油分が放出されたり、可動吊子２のスライド移動により流れ出したりして持続効果が低く、本発明の方が優れるものである。現実に、長期にわたって使用する屋根で且つ二重折板屋根の場合、メンテナンスがほとんど不可能であり、本発明によればメンテナンスフリーが可能であり、持続効果も期待することができる。 As described above, according to the present invention, by providing the protrusion 25, the friction between the receiving member 1 and the movable suspension 2 can be reduced and the mobility can be improved as compared with the conventional structure without the protrusion 25. In addition, the movable suspension 2 can be smoothly slid by absorbing the distortion of the building structural material such as the main building and the variation in construction. In order to reduce the friction between the receiving member 1 and the movable suspension 2, a technique of applying lubricating oil is also considered. However, the maintainability is low, the oil is released by heat or the like, or the movable suspension 2.
