ところで、これら従来のタイトフレームに設けられる係止受部と折版屋根材の係止部との係合状態は、タイトフレームの係止受部の下端縁に折版屋根材の係止部の係止面が当接するものであり、タイトフレームの係止受部の下端縁は、角張っていたりタイトフレームから切り起こした際の切断面のままで先鋭な状態となっていることが多く、そのため、この下端縁と当接する折版屋根材の係止面には、取り付け作業時に係止受部の下端縁によってキズが付けられることが多かった。 By the way, the engagement state of the latch receiving part provided in these conventional tight frames and the latching part of the folding roof material is such that the latching part of the folding roof material is provided at the lower end edge of the locking receiver of the tight frame. The locking surface comes into contact, and the lower end edge of the locking receiving portion of the tight frame is often sharp or sharp with the cut surface when cut and raised from the tight frame. The locking surface of the stencil roofing material that comes into contact with the lower edge is often scratched by the lower edge of the locking receiving portion during the mounting operation.

また更に、この折版屋根材は、金属製であるため、温度（気温）の変化によって体積が膨張したり収縮したりするので、この膨張収縮によって長さも伸縮する性質があり、この折版屋根材の伸縮作用によって、タイトフレームの係止受部に当接している折版屋根材の係止部の係止面が移動することで、設置後も多くのキズが付き、これら取り付け時のキズや取り付け後の折版屋根材の伸縮作用によって繰り返しキズが付けられることで、厚さの薄い折版屋根材が局所的に一層薄くなってしまい、折版屋根材の耐久性を低下してしまうという問題があった。 Furthermore, since the folding roof material is made of metal, the volume expands and contracts due to changes in temperature (air temperature), and therefore the expansion and contraction has the property that the length expands and contracts. Due to the expansion and contraction of the material, the locking surface of the locking part of the stencil roofing material that is in contact with the locking receiving part of the tight frame moves, so there are many scratches even after installation. Or repeatedly attached scratches by the expansion and contraction action of the folding roof material after installation, the thin folding roof material becomes locally thinner and the durability of the folding roof material is reduced. There was a problem.

本発明は、従来のタイトフレームにおける上述の問題を解決し、タイトフレームの係止受部を、折版屋根材の係止面に対してキズを付け難い形状に構成し、折版屋根材を取り付ける際や取り付けた後にもこの折版屋根材の係止面にキズを付けることがなく、折版屋根材の耐久性を損ねることがない画期的なタイトフレームを提供することを目的とする。 The present invention solves the above-mentioned problems in the conventional tight frame, and the tight receiving portion of the tight frame is configured in a shape that is difficult to scratch the locking surface of the folded roof material. The purpose of the present invention is to provide an innovative tight frame that does not damage the engagement surface of the engraved roofing material even when it is installed or after installation, and does not impair the durability of the engraved roofing material. .

添付図面を参照して本発明の要旨を説明する。 The gist of the present invention will be described with reference to the accompanying drawings.

折版屋根材１を梁材に固定する際に用いるタイトフレーム２であって、このタイトフレーム２の左右夫々の斜辺部３に凹字状の切欠き孔４を設け、この凹字状の切欠き孔４のタイトフレーム頂部５側を前記斜辺部３の上部側から下部側に向かって徐々に膨出度合いが大きくなるように外方に向かって膨出させて下端に板片を有する外面が湾曲した半釣鐘形状の膨出部６を設け、この膨出部６下端の板片を、この板片の基端部から折曲部９の外周面がＲ形状となるようにして下端縁を内側に向けて前記斜辺部３の傾斜面３ａに対して略直交するように折曲して前記折版屋根材１の係止部７が係止する板片状の係止受部８を設け、前記タイトフレーム２に前記折版屋根材１を嵌合係止した際に、前記係止受部８の下側板面８ａと前記折版屋根材１の係止部７の係止面７ａとの面同士が接触係合して、この折版屋根材１の係止部７が前記タイトフレーム２の斜辺部３に設けた係止受部８に引っ掛かり係止するように構成したことを特徴とするタイトフレームに係るものである。 A tight frame 2 used for fixing the folded roofing material 1 to a beam material. A concave cutout hole 4 is provided in each of the left and right oblique sides 3 of the tight frame 2 to form the concave cutout. The outer surface having a plate piece at the lower end is formed by bulging the tight frame top 5 side of the notched hole 4 outward so that the degree of bulging gradually increases from the upper side of the oblique side 3 toward the lower side. A curved semi-bell shaped bulging portion 6 is provided, and the lower end edge of the bulging portion 6 has a lower end edge so that the outer peripheral surface of the bent portion 9 has an R shape from the base end portion of the bulging portion 6. the plate piece-like lock receiving portion 8 of the engaging portion 7 of said bent folded plate roofing material 1 is locked so as to be substantially perpendicular to the inclined surface 3a of the slant portion 3 provided toward the inside When the folded roof material 1 is fitted and locked to the tight frame 2, the lower plate surface 8a of the locking receiving portion 8 and the folded roof material 1 are fixed. Face each other and the locking surface 7a of the locking portion 7 is in contact engagement with, caught by the lock receiving portion 8 of the engaging portion 7 of the folding plate roofing material 1 is provided in the inclined portion 3 of the tight frame 2 The present invention relates to a tight frame that is configured to be locked.

本発明は上述のように構成したから、タイトフレームに折版屋根材を取り付ける際や取り付けた後に、この折版屋根材に係止受部によるキズが付かないので、折版屋根材の耐久性を低下させることがない、実用性に優れた画期的なタイトフレームとなる。 Since the present invention is configured as described above, when the folded roofing material is attached to the tight frame or after it is attached, the folded roofing material is not scratched by the locking receiving portion, so the durability of the folded roofing material It is an epoch-making tight frame excellent in practicality that does not lower the thickness.

即ち、従来のタイトフレームは、折版屋根材の係止部の係止面と点接触、若しくは線接触であることに対して、本発明の係止受部は、係止部の下側板面が折版屋根材の係止部の係止面と面接触する構成としているので、従来のように先鋭な切削面が当接するのではなく、滑らかで平坦な面同士が当接し合うことで従来に比して折版屋根材の耐久性を損ねるようなキズを付けるようなことはなくなる。 That is, the conventional tight frame is in point contact or line contact with the engaging surface of the engaging portion of the folding roof material, whereas the engaging receiving portion of the present invention is the lower plate surface of the engaging portion. Is configured to be in surface contact with the locking surface of the locking portion of the folding roofing material, so that the sharp cutting surface does not contact as in the conventional case, but the smooth and flat surfaces contact each other. Compared to this, there will be no scratches that impair the durability of the folding roofing material.

しかも、折版屋根材の係止部をタイトフレームの係止受部の下側板面が受け止める、即ち、面を面で受け止める面接触構成としたので、従来の嵌合強度（係止強度）に比して、より強固に嵌合（係止）することができ、強風などによって折版屋根材が剥離方向に吹き上げられても、この折版屋根材がタイトフレームから容易に脱離することなく、係止状態が強固に保持される実用性に優れたタイトフレームとなり、更に、面接触としたことで接触圧が分散され、点接触や線接触に比して接触圧が軽減されることで、より一層キズが付き難くなる。 Moreover, since the lower plate surface of the tight frame locking receiving portion receives the locking portion of the folded roof material, that is, a surface contact configuration in which the surface is received by the surface, the conventional fitting strength (locking strength) is achieved. In comparison, it can be fitted (locked) more firmly, and even if the folding roof material is blown up in the peeling direction by a strong wind or the like, the folding roof material is not easily detached from the tight frame. It becomes a tight frame with excellent practicality in which the locked state is firmly held, and furthermore, contact pressure is dispersed by using surface contact, and contact pressure is reduced compared to point contact and line contact. , It becomes even more difficult to get scratched.

従って、タイトフレームに折版屋根材を取り付ける際や、タイトフレームに折版屋根材を取り付けた後も、折版屋根材の係止面にキズが付くことが殆どないので、このキズによって折版屋根材の耐久性が低下することがなく、また、キズが原因で折版屋根材が錆びてしまい耐久性どころか体裁を損ねてしまうという不具合が生じることがない実用性に優れた画期的なタイトフレームとなる。 Therefore, when attaching the folding roofing material to the tight frame or after attaching the folding roofing material to the tight frame, the engagement surface of the folding roofing material is hardly scratched. The durability of the roofing material is not reduced, and the stencil roofing material is rusted due to scratches, so that it does not have the problem of impairing the appearance as well as the durability. It becomes a tight frame.

また、本発明は、折版屋根材をタイトフレームに取り付ける際に、この折版屋根材をタイトフレームの係止受部に滑らかに嵌合することができるので、より一層折版屋根材の係止部の係止面にキズが付き難くなる実用性に優れたタイトフレームとなる。 Further, according to the present invention , when the folded roofing material is attached to the tight frame, the folded roofing material can be smoothly fitted into the locking receiving portion of the tight frame. It becomes a tight frame excellent in practicality in which scratches are difficult to be scratched on the locking surface of the stopper.

また、更に本発明は、折版屋根材の剥離方向の力を正面から受けることで膨出部による強度の向上の効果がより一層発揮されることとなり、折版屋根材から強い力を受けても係止受部が変形して捲れあがったり、破損したりせずに強固に折版屋根材を受け止めることができる耐久性に優れたタイトフレームとなる。 In addition, the present invention further exerts the effect of improving the strength by the bulging portion by receiving the force in the peeling direction of the folded roof material from the front, and receives the strong force from the folded roof material. However, the lock receiving portion is deformed, and it becomes a tight frame excellent in durability that can firmly receive the folded roofing material without being rolled up or damaged.

また、本発明は、タイトフレームの上方から折版屋根材を被嵌し下方に押し込むことで、折版屋根材が膨出部の下端側で外形状に沿って広げられて押し込まれ、この膨出部の下端を乗り越えたところで折版屋根材の戻り付勢によって、この折版屋根材の係止部がタイトフレームの係止受部と強固に嵌合して引っ掛かり係止状態となって固定されるので、一々、折版屋根材を広げながらタイトフレームに押し嵌めるといった煩わしい作業をする必要がなく、更に、膨出部の下端側の膨出度合いを大きくしたので、係止面積を大きく設定することができ、よって、折版屋根材の係止部がタイトフレームの係止受部から脱離し難くなるので、折版屋根材をタイトフレームに、スムーズ、且つワンタッチで取り付けることができるとともに、強固に折版屋根材をタイトフレームに取り付け固定することができる作業性且つ実用性に優れたタイトフレームとなる。 Further, the present invention is such that the folding roof material is fitted and pushed downward from above the tight frame, and the folding roof material is spread and pushed along the outer shape on the lower end side of the bulging portion. After the lower end of the protruding portion is overcome, the folding force of the folding roofing material is firmly engaged with the locking receiving portion of the tight frame by the biasing force of the folding roofing material and fixed in a locked state. Therefore, there is no need to perform the troublesome work of pressing and fitting to the tight frame while spreading the folding roof material, and the degree of bulging on the lower end side of the bulging part has been increased, so the locking area is set large. Therefore, the locking portion of the folding roof material is difficult to be detached from the locking receiving portion of the tight frame, so that the folding roof material can be attached to the tight frame smoothly and with one touch, Fold firmly A tight frame with excellent workability and practicality can be fixed attached roofing tight frame.

好適と考える本発明の実施形態を、図面に基づいて本発明の作用を示して簡単に説明する。 An embodiment of the present invention which is considered to be suitable will be briefly described with reference to the drawings showing the operation of the present invention.

本発明のタイトフレーム２に折版屋根材１を被嵌した際に、このタイトフレーム２の斜辺部３に設けた板片状の係止受部８の下側板面８ａと、折版屋根材１の係止部７の係止面７ａとが面同士で当接し合うので、折版屋根材１の係止面７ａにキズが付くことが殆どなくなることとなる。 When the folded roof material 1 is fitted on the tight frame 2 of the present invention, the lower plate surface 8a of the plate-like locking receiving portion 8 provided on the oblique side portion 3 of the tight frame 2, and the folded roof material Since the locking surfaces 7a of the one locking portion 7 come into contact with each other, the locking surface 7a of the stencil roofing material 1 is hardly scratched.

即ち、従来のタイトフレームは、タイトフレームの斜辺部に外方且つ下向きに突設した板片状の係止受部の下端面或いは下端縁が折版屋根材１の係止面７ａに当接する構成となっており、この折版屋根材１の係止面７ａと当接する係止受部は、タイトフレームの斜辺部を切り起こして形成したものが多く、よって、係止受部の下端面（下端縁）は、斜辺部を切り欠いた際の切削面の縁部が先鋭な状態のままであったり、板片の端面ということで接触面が非常に狭小な面積となり応力が集中してしまうため、よりキズを付け易い状態となっている。 That is, in the conventional tight frame, the lower end surface or the lower end edge of the plate-like locking receiving portion protruding outward and downward on the oblique side portion of the tight frame abuts on the locking surface 7a of the folding roof material 1. Many of the latch receiving portions that are configured and come into contact with the latching surface 7a of the folded roofing material 1 are formed by cutting and raising the oblique sides of the tight frame. (Lower edge) The edge of the cut surface when the hypotenuse is notched remains sharp, or the contact surface becomes very narrow due to the end face of the plate piece, and stress is concentrated. Therefore, it is in a state where it is easier to scratch.

また、このようなキズを付けないために係止受部の折版屋根材１の係止面７ａとの当接部を、キズを付け難い形状に処理するには手間がかかり、その分、コストアップにつながり、安価に製品を提供できなくなるため、殆どのタイトフレームでは、このような係止受部の切削面の処理は十分に行われることがない
これに対して、本発明は、係止受部８の下端面（下端縁）を当接させるのではなく、内側に折曲して外側板面であった面を下側板面８ａとなるように構成し、この下側板面８ａが従来の係止受部の下端面となることで、切り欠き面が当接することがなく、しかも、接触面積が従来に比して広大となり応力が分散されるので、より一層キズが付き難い状態に構成している。 Further, in order to prevent such scratches, it takes time and effort to process the contact portion of the latch receiving portion with the locking surface 7a of the folded roofing material 1 into a shape that is difficult to scratch. Since this leads to an increase in cost and it becomes impossible to provide a product at a low cost, the processing of the cutting surface of such a locking receiving portion is not sufficiently performed in most tight frames. The lower end surface (lower end edge) of the stopper 8 is not brought into contact, but the surface that is the outer plate surface is bent to the inner side so as to become the lower plate surface 8a. By being the lower end surface of the conventional latch receiving part, the notch surface does not come into contact, and the contact area is larger than before and the stress is dispersed, making it even more difficult to scratch It is configured.

即ち、従来の係止受部は、折版屋根材１の係止面７ａと点接触、若しくは線接触であることに対して、本発明の係止受部８は、折版屋根材１の係止面７ａと面接触としているので、この滑らかで平坦な面同士が当接し合うこと、更には、接触圧も分散されることで嵌合時にキズが付き難い構成となり、よって、タイトフレーム２に折版屋根材１を取り付ける際や、タイトフレーム２に折版屋根材１を取り付けた後も、折版屋根材１の係止面７ａにキズが付くことが殆どないので、このキズによって折版屋根材１の耐久性が低下することがなく、また、キズが原因で折版屋根材１が錆びてしまい耐久性どころか体裁を損ねてしまうという不具合が生じることがない実用性に優れた画期的なタイトフレームとなる。 That is, the conventional latch receiving part is a point contact or a line contact with the latching surface 7a of the folded roof material 1, whereas the latch receiving part 8 of the present invention is the Since the surface is in contact with the locking surface 7a, the smooth and flat surfaces come into contact with each other, and further, the contact pressure is also dispersed so that it is difficult to be scratched during fitting. When the folding roof material 1 is attached to the tight frame 2 or after the folding roof material 1 is attached to the tight frame 2, the engaging surface 7a of the folding roof material 1 is hardly scratched. The durability of the slab roofing material 1 is not lowered, and the stencil roofing material 1 is rusted due to scratches. It becomes a period tight frame.

また更に、この折版屋根材の係止部とタイトフレームの係止受部とを面接触としたことで、嵌合強度（係止強度）も向上し、より強固に折版屋根材１をタイトフレーム２に固定し得ることが可能となる。 Furthermore, the engagement portion (engagement strength) is improved by making the engagement portion of the folding roof material and the engagement receiving portion of the tight frame in surface contact, and the folding roof material 1 is more firmly attached. It can be fixed to the tight frame 2.

また、このタイトフレーム２に被嵌した折版屋根材１は、例えば、強風などによって剥離方向の強い力を受けることがあり、この際、この折版屋根材１の剥離方向の強大な力をタイトフレーム２の係止受部８が受け止めることで折版屋根材１が剥離し飛ばされることを防いでいる。よって、この係止受部８が折版屋根材１から押圧された際に容易に変形したり破損してしまっては、折版屋根材１を強固に保持することはできないので、よって、この係止受部８は、強風などによって折版屋根材１が受ける強大な力を受け止めるだけの強度（耐久性）が必要であり、本発明は、この点、折版屋根材１の係止部７を受け止める係止受部８を面で受け止める構成とし、尚且つ、タイトフレーム２の斜辺部３を膨出させてタイトフレーム２と一体成形されている膨出部６とこの係止受部８を一体成形してこの係止受部８が受ける力を膨出部６で受け止める構成としたので、強固な力を受けても係止受部８が捲れあがったり破損してタイトフレーム２から離脱してしまうことがなく極めて強固に折版屋根材１を係止することが可能な耐久性に優れたタイトフレームとなる。 Further, the folded roof material 1 fitted to the tight frame 2 may receive a strong force in the peeling direction due to, for example, strong winds. At this time, a strong force in the peeling direction of the folded roof material 1 is applied. When the latch receiving part 8 of the tight frame 2 receives, the folded roof material 1 is prevented from being peeled off. Therefore, if the latch receiving portion 8 is easily deformed or damaged when pressed from the folded roof material 1, the folded roof material 1 cannot be firmly held. The latch receiving portion 8 needs to have enough strength (durability) to receive the strong force received by the folding roof material 1 due to a strong wind or the like. The latch receiving portion 8 for receiving 7 is received by the surface, and the bulging portion 6 formed integrally with the tight frame 2 by expanding the oblique side portion 3 of the tight frame 2 and the latch receiving portion 8. Is formed so that the force received by the latch receiving portion 8 is received by the bulging portion 6, so that the latch receiving portion 8 is rolled up or damaged even when a strong force is received, and is detached from the tight frame 2. It is possible to lock the folding roof material 1 very firmly without having to An excellent tight frame to durability.

即ち、本実施例の係止受部８は、係止受部８の下側板面８ａが折版屋根材１の係止部７の係止面７ａと面接触により嵌合し、従来のタイトフレームの係止受部のように点接触や線接触での嵌合ではないので、従来に比し、より嵌合強度（係止強度）を向上した構成とし、しかも、本実施例の係止受部８は、斜辺部３を打ち出して膨出させて形成した膨出部６の下端に設けた構成とし、更に、この膨出部６と係止受部８とは、もともと、斜辺部３の傾斜面３ａの一部であり、よって、これらは一体成形されているので、この係止受部８が折版屋根材１から受ける力、例えば、強風などによって折版屋根材１が剥離方向に吹き上げられた際に生じる押圧力を膨出部６で強固に受け止める構成としている。 That is, the latch receiving portion 8 of the present embodiment is fitted with the locking surface 7a of the latching portion 7 of the stencil roofing material 1 by surface contact with the lower plate surface 8a of the latch receiving portion 8, and the conventional tight Since it is not fitting by point contact or line contact like the frame lock receiving part, it has a structure with improved fitting strength (locking strength) compared to the conventional one, and the locking of this embodiment The receiving part 8 is provided at the lower end of the bulging part 6 formed by projecting and projecting the oblique side part 3, and the bulging part 6 and the locking receiving part 8 are originally composed of the oblique side part 3. Since these are integrally formed, the folding roof material 1 is peeled in the peeling direction by the force received by the latch receiving portion 8 from the folding roof material 1, such as strong wind. The bulging portion 6 firmly receives the pressing force generated when the air is blown up by the bulge.

よって、本実施例の係止受部８は、従来のタイトフレームの係止受部に比して、極めて嵌合強度に優れた係止受部８に構成している。 Therefore, the latch receiving portion 8 of the present embodiment is configured as a latch receiving portion 8 that is extremely excellent in fitting strength as compared with a conventional tight frame latch receiving portion.

また、本実施例のタイトフレーム２は、折版屋根材１を支持する際の耐久性を向上させるため、折版屋根材支持部10の強度を向上した構成としている。 In addition, the tight frame 2 of this embodiment has a configuration in which the strength of the folded roof material support portion 10 is improved in order to improve durability when the folded roof material 1 is supported.

具体的には、図２に示すように、タイトフレーム頂部５と左右の斜辺部３との前後方向（帯板材の短手方向）の端部に補強縁部12を設けた構成とし、より具体的には、この補強縁部12は、タイトフレーム頂部５及び左右の斜辺部３の前後端縁を内側方向に直角に折曲して形成して、折版屋根材支持部10を断面コ字状に形成した構成としている。 Specifically, as shown in FIG. 2, a reinforcing edge 12 is provided at the ends of the tight frame top 5 and the left and right oblique sides 3 in the front-rear direction (short direction of the strip), more specifically. Specifically, the reinforcing edge portion 12 is formed by bending the front and rear end edges of the tight frame top portion 5 and the left and right oblique side portions 3 at right angles to the inner side, thereby forming the folded roof material support portion 10 in a U-shaped cross section. It is set as the structure formed in the shape.

以上のように構成した本実施例のタイトフレーム２に、折版屋根材１を取り付ける際は、図５（ａ）に示すように、最初に取り付けた折版屋根材１の端部と新たに取り付ける折版屋根材１の端部同士が重なるように、具体的には、折版屋根材１に設けてあるハゼ嵌合部13同士を嵌合するようにして、タイトフレーム２の上方から折版屋根材１を被嵌する。 When the folding roof material 1 is attached to the tight frame 2 of the present embodiment configured as described above, as shown in FIG. Folded from above the tight frame 2 so that the ends of the folding roof material 1 to be attached overlap each other, specifically, the seam fitting portions 13 provided on the folding roof material 1 are fitted together. The plate roof material 1 is fitted.

この被嵌した折版屋根材１を下方に押し込んで行くと、図５（ｂ）並びに図６に示すように、タイトフレーム２の斜辺部３に設けた半釣鐘形状に形成した膨出部６に折版屋根材１の内面が当接して折版屋根材１が左右方向に押し広げられる。 When the fitted folding roofing material 1 is pushed downward, as shown in FIG. 5B and FIG. 6, the bulging portion 6 formed in a semi-bell shape provided in the oblique side portion 3 of the tight frame 2. The inner surface of the folded roofing material 1 is brought into contact with the folded roofing material 1 so that the folded roofing material 1 is expanded in the left-right direction.

この折版屋根材１が左右に押し広げられた状態で、更に下方に押し込むことで、図５（ｃ）並びに図７に示すように、折版屋根材１の内面当接部がこの膨出部６を乗り越え、折版屋根材１の内面に設けられている係止部７の係止面７ａが、タイトフレーム２の係止受部８の下側板面８ａと面接触状態で嵌合することとなる。 When the folded roofing material 1 is pushed to the left and right and further pushed downward, the inner surface contact portion of the folded roofing material 1 bulges as shown in FIGS. The locking surface 7a of the locking portion 7 provided on the inner surface of the folded roofing material 1 is fitted over the lower plate surface 8a of the locking receiving portion 8 of the tight frame 2 in a surface contact state. It will be.

最後に、図５（ｄ）に示すように、折版屋根材１の嵌合したハゼ嵌合部13を締め付けて、折版屋根材１同士を連結固定することで取り付けが完了する。 Finally, as shown in FIG.5 (d), the goby fitting part 13 which the folding roof material 1 fitted is fastened, and attachment is completed by connecting and fixing the folding roof materials 1 mutually.

このように、本実施例のタイトフレーム２を用いて折版屋根材１を取り付ける際は、折版屋根材１をタイトフレーム２に押し込んで被嵌するだけのワンタッチ作業で容易に取り付けることができるように構成している。 Thus, when attaching the folding roof material 1 using the tight frame 2 of the present embodiment, the folding roof material 1 can be easily attached by a one-touch operation of pushing the folding roof material 1 into the tight frame 2 and fitting it. It is configured as follows.

本実施例は、以上のように構成したので、以下のような作用効果を奏する。 Since the present embodiment is configured as described above, the following effects can be obtained.

本実施例は、膨出部６下端から突出している係止受部８を内側に折曲して、この係止受部８の下側板面８ａが折版屋根材１の係止部７の係止面７ａと嵌合するように構成したので、従来の係止受部は、折版屋根材１の係止面７ａと点接触、若しくは線接触であることに対して、本実施例の係止受部８は、折版屋根材１の係止面７ａと面接触としているので、この滑らかで平坦な面同士が当接し合うこと、更には、接触圧も分散されることで係止時にキズが付き難い構成となり、よって、タイトフレーム２に折版屋根材１を取り付ける際に、折版屋根材１の係止面７ａにキズが付くことが殆どないので、折版屋根材１の耐久性が低下することを可及的に低減することができる。 In the present embodiment, the locking receiving portion 8 protruding from the lower end of the bulging portion 6 is bent inward, and the lower plate surface 8a of the locking receiving portion 8 is formed on the locking portion 7 of the folding roof material 1. Since it comprised so that it might fit with the latching surface 7a, the conventional latching receiving part is a point contact with the latching surface 7a of the stencil roofing material 1, or a line contact, and a present Example. Since the latch receiving portion 8 is in surface contact with the latching surface 7a of the folded roofing material 1, the smooth and flat surfaces are brought into contact with each other, and furthermore, the contact pressure is also dispersed to be latched. At times, when the folding roof material 1 is attached to the tight frame 2, the engagement surface 7a of the folding roof material 1 is hardly scratched. It can reduce as much as possible that durability falls.

また、本実施例は、膨出部６を斜辺部３の上部側から下部側に向かって徐々に膨出度合いが大きくなる錐体状に形成した構成としたので、タイトフレーム２の上方から折版屋根材１を被嵌し下方に押し込むことで、折版屋根材１が膨出部６の下端側で外形状に沿って広げられて押し込まれ、この膨出部６の下端を乗り越えたところで折版屋根材１の戻り付勢によって、この折版屋根材１の係止部７がタイトフレーム２の係止受部８と強固に嵌合して引っ掛かり係止状態となって固定されるので、一々、折版屋根材１を広げながらタイトフレーム２に押し嵌めるといった煩わしい作業をする必要がなく、更に、膨出部６の下端側の膨出度合いを大きくしたので、係止面積を大きく設定することができ、よって、折版屋根材１の係止部７がタイトフレーム２の係止受部８から脱離し難くなるので、折版屋根材１をタイトフレーム２に、スムーズ、且つワンタッチで取り付けることができるとともに、強固に折版屋根材１をタイトフレーム２に取り付け固定することができる作業性且つ実用性に優れたタイトフレームとなる。 Further, in the present embodiment, the bulging portion 6 is formed in a conical shape in which the degree of bulging gradually increases from the upper side to the lower side of the oblique side portion 3, so that the fold portion 6 is folded from above the tight frame 2. When the plate roof material 1 is fitted and pushed downward, the folded roof material 1 is expanded and pushed in along the outer shape on the lower end side of the bulging portion 6, and the lower end of the bulging portion 6 is overcome. By the return bias of the folding roof material 1, the locking portion 7 of the folding roof material 1 is firmly engaged with the locking receiving portion 8 of the tight frame 2 and is locked in a locked state. In addition, it is not necessary to carry out the troublesome work of pressing and fitting the tight roof frame 1 while expanding the folded roof material 1, and further, since the degree of bulging on the lower end side of the bulging portion 6 is increased, the locking area is set large. Therefore, the locking part 7 of the folded roofing material 1 is tight. Since it is difficult to detach from the latch receiving portion 8 of the ram 2, the folded roof material 1 can be attached to the tight frame 2 smoothly and with one touch, and the folded roof material 1 is firmly attached to the tight frame 2. The tight frame is excellent in workability and practicality that can be fixed.

また更に、本実施例は、折版屋根材１の内面が当接する膨出部６の外面や、膨出部６から係止受部８に掛かる折曲部９を滑らかな弯曲形状（Ｒ形状）に形成した構成としたので、折版屋根材１を押し込んでタイトフレーム２に被嵌する際に、折版屋根材１をより一層スムーズに押し込むことができ、しかも、押し込み移動させている折版屋根材１の内面にも、ほとんどキズが付かない画期的なタイトフレームとなる。 Furthermore, in this embodiment, the outer surface of the bulging portion 6 with which the inner surface of the folding roof material 1 abuts, and the bent portion 9 that hangs from the bulging portion 6 to the locking receiving portion 8 are smoothly bent (R-shaped). ), The folded roofing material 1 can be pushed more smoothly when the folded roofing material 1 is pushed into the tight frame 2 and the folding roof material 1 is pushed and moved. The inner surface of the plate roof material 1 also becomes an epoch-making tight frame with almost no scratches.

尚、本発明は、本実施例に限られるものではなく、各構成要件の具体的構成は適宜設計し得るものである。 Note that the present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate.
