Description

本発明は、折板屋根材を支持するタイトフレームを、屋根下地材に溶接することなく固定できるタイトフレーム固定装置に関するものである。 The present invention relates to a tight frame fixing device that can fix a tight frame that supports a folded-plate roof material to the roof base material without welding it.

折板構造屋根は、Ｈ型鋼やＩ型鋼などで構成された屋根下地材（母屋）の上面に沿って固定された横長のタイトフレーム上に、折板屋根材が順次被嵌支持されて取付固定されることによって構成されている（例えば、特許文献１参照。）。 A folded-plate structure roof is constructed by sequentially fitting and supporting folded-plate roofing materials onto a horizontally long tight frame that is fixed along the top surface of a roof base material (main structure) made of H-shaped steel or I-shaped steel, etc. (For example, see Patent Document 1).

ところで、タイトフレームは、屋根下地材に対して溶接固定されるのが一般的であるが、昨今は施主から火の取り扱いを控えて欲しいという要望があって溶接作業自体が困難な現場があったりする。また、海沿い等の塩害が懸念される地域では、タイトフレームに錆付き防止のための鍍金を施したいという要望も多く、これに応えるべくタイトフレームに鍍金を施すことによって溶接による固定が非常に困難となるケースもある。 Generally, tight frames are fixed to the roof underlayment by welding, but in recent years, clients have requested that the handling of fire be avoided, making welding difficult at some sites. Also, in areas where salt damage is a concern, such as coastal areas, there are many requests to plate the tight frames to prevent rust, and in some cases plating the tight frames in response to this makes fixing them by welding extremely difficult.

そこで従来、タイトフレームの屋根下地材への固定手段として、溶接せずに固定できる無溶接固定具が開発されている（特許文献２参照）。 Therefore, non-welding fasteners that can fasten tight frames to roof underlayment without welding have been developed (see Patent Document 2).

この特許文献２を簡単に説明すると、受部本体（タイトフレーム）と、この受部本体が設置されると共に受部本体の設置位置を中心として両側に貫通孔が形成された長方形状の台座と、断面コ字形状で且つ上片側に締付螺子部が設けられてなる二つの係止部材とを具備し、前記係止部材の前記締付螺子部は前記台座の前記貫通孔に貫通されると共に、前記係止部材は水平面上を回動自在とすると共に前記締付螺子部の締付にて固定されてなるものであって、台座に装着された両係止部材を、屋根下地材としてのＨ型鋼或いはＩ型鋼のフランジに被嵌した上で、締付螺子部を締付することによって係止固定できるように構成されている。 To briefly explain this patent document 2, it comprises a receiving body (tight frame), a rectangular base on which the receiving body is installed and which has through holes on both sides centered on the installation position of the receiving body, and two locking members with a U-shaped cross section and a tightening screw on the upper side, the tightening screw of the locking member passes through the through hole of the base, the locking member is rotatable on a horizontal plane, and is fixed by tightening the tightening screw, and both locking members attached to the base are fitted over the flanges of H-beam or I-beam used as roof underlayment, and can be locked and fixed by tightening the tightening screw.

上記特許文献２では、既存の安価なタイトフレームを使用することができず、台座と係止部材とが設けられた専用設計のタイトフレーム（受部本体）を多数用意する必要があるために施工コスト高となってしまう問題点があった。 The problem with Patent Document 2 above is that it is not possible to use existing inexpensive tight frames, and it is necessary to prepare a large number of specially designed tight frames (receiving body) equipped with bases and locking members, resulting in high construction costs.

本発明は、このような従来の無溶接タイトフレーム固定具の問題点に注目し、これを解決しようとするためのもので、既存のタイトフレームを無溶接で屋根下地材に固定することができるタイトフレーム固定装置を提供するものである。 The present invention focuses on and seeks to solve the problems associated with conventional non-welded tight frame fasteners, and provides a tight frame fastening device that can fasten existing tight frames to roof underlayment without welding.

本発明の最適な実施形態を、図面に基づいて本発明の作用を示し簡単に説明する。 The optimal embodiment of the present invention will be briefly explained with reference to the drawings, showing the operation of the present invention.

屋根下地材１上に載置されたタイトフレーム２の載置部３に、押え部材４の交差重合部５を上方から交差状態に重ねて載置すると、タイトフレーム２の長さ方向と直交する載置部３の一方側に押え部材４の一方側端部６が突出状態に配設されると共に、載置部３の反対側に反対側端部６が突出状態に配設される。 When the cross-over portion 5 of the pressing member 4 is placed crosswise from above on the mounting portion 3 of the tight frame 2 placed on the roof underlayment 1, one end 6 of the pressing member 4 is arranged in a protruding state on one side of the mounting portion 3 perpendicular to the length direction of the tight frame 2, and the opposite end 6 is arranged in a protruding state on the opposite side of the mounting portion 3.

次いで、屋根下地材１とこの屋根下地材１上に載置されている前記押え部材４の両側端部６を上下から挟み込むようにして固定部材７の固定基体８を取付け、この固定基体８に設けられている締付ボルト９を締付操作して押え部材４の端部６若しくはこの押え部材４の端部６が載置されている屋根下地材１に締付圧接させると、押え部材４が屋根下地材１に締付固定されて、押え部材４に前記タイトフレーム２（の載置部３）が押え込まれて屋根下地材１上に固定される。 Next, the fixed base 8 of the fixing member 7 is attached so as to sandwich from above and below both side ends 6 of the roof underlayment 1 and the pressing member 4 placed on the roof underlayment 1, and the tightening bolts 9 provided on the fixed base 8 are tightened to press the end 6 of the pressing member 4 or the roof underlayment 1 on which the end 6 of the pressing member 4 is placed, so that the pressing member 4 is tightened and fixed to the roof underlayment 1, and the tight frame 2 (the mounting portion 3) is pressed into the pressing member 4 and fixed onto the roof underlayment 1.

従って、本発明の押え部材４と固定部材７とから成るタイトフレーム固定装置Ａを用いることにより、既存の安価なタイトフレーム２を溶接手段を要することなく屋根下地材１上に固定できる。 Therefore, by using the tight frame fixing device A consisting of the clamping member 4 and fixing member 7 of the present invention, an existing inexpensive tight frame 2 can be fixed onto the roof underlayment 1 without the need for welding means.

本発明の具体的な実施例について図面に基づいて説明する。 Specific examples of the present invention will be described with reference to the drawings.

本実施例は、折板構造屋根のタイトフレーム２をＨ型鋼やＩ型鋼などの鉄骨で構成された屋根下地材１上に固定するためのタイトフレーム固定装置Ａに係るものであって、屋根下地材１上に載置されたタイトフレーム２の載置部３に上方から交差状態に重ねて載置される押え部材４と、この押え部材４の両側端部６を前記屋根下地材１に締付固定して前記タイトフレーム２を屋根下地材１上に押え込み固定する前後一対の固定部材７（第一固定部材７Ａと第二固定部材７Ｂ）とから成るものに構成されている。尚、図面は、タイトフレーム嵌合式と称される折板構造屋根用のタイトフレーム２を採用した場合を図示しているが、本実施例は、重ね式折板構造屋根用のタイトフレーム２の固定や、ハゼ式折板構造屋根用のタイトフレーム２の固定にも使用可能である。また、本実施例では、タイトフレーム２の谷部３を前記載置部３とした場合を示している（以下、本実施例では載置部３を谷部３と称して説明する。）。 This embodiment relates to a tight frame fixing device A for fixing a tight frame 2 of a folded plate structure roof to a roof base material 1 made of steel such as H-shaped steel or I-shaped steel, and is composed of a pressing member 4 that is placed on the placement part 3 of the tight frame 2 placed on the roof base material 1 in a cross state from above, and a pair of front and rear fixing members 7 (first fixing member 7A and second fixing member 7B) that fasten and fix both side ends 6 of the pressing member 4 to the roof base material 1 to press and fix the tight frame 2 on the roof base material 1. Note that the drawing shows a case where a tight frame 2 for a folded plate structure roof called a tight frame fitting type is used, but this embodiment can also be used to fix a tight frame 2 for a folded plate structure roof with a lapped type or a tight frame 2 for a seam type folded plate structure roof. In addition, this embodiment shows a case where the valley part 3 of the tight frame 2 is the placement part 3 described above (hereinafter, in this embodiment, the placement part 3 is referred to as the valley part 3 and described.).

具体的には、本実施例の前記押え部材４は、図１～図４に示すように、平面視長方形状の金属板で構成されており、この金属板の中間部が前記タイトフレーム２の谷部３上にこのタイトフレーム２の長さ方向と交差するように（タイトフレーム２と押え部材４とが直交状態となるように）重ねて配設（載置）される交差中央部５として構成され、この際タイトフレーム２の長さ方向と直交する谷部３の一方側に突出状態に配設される一方側端部６と、谷部３の反対側に突出状態に配設される反対側端部６とを有するように金属板の長さ寸法が設定構成されている。尚、本実施例のタイトフレーム固定装置Ａは、説明の都合上、屋根下地材１及びタイトフレーム２の長さ方向に対向する方向を左右方向、タイトフレーム２の長さ方向と直交する方向に対応する方向を前後方向と定めて、以下説明する。 Specifically, as shown in Figs. 1 to 4, the clamping member 4 in this embodiment is made of a metal plate that is rectangular in plan view, and the middle part of this metal plate is configured as an intersecting central part 5 that is placed on the valley part 3 of the tight frame 2 so as to intersect with the length direction of the tight frame 2 (so that the tight frame 2 and the clamping member 4 are perpendicular to each other), and the length dimension of the metal plate is set so that it has one side end 6 that is arranged in a protruding state on one side of the valley part 3 that is perpendicular to the length direction of the tight frame 2, and the other side end 6 that is arranged in a protruding state on the opposite side of the valley part 3. For convenience of explanation, the tight frame fixing device A in this embodiment will be described below by defining the direction that faces the length direction of the roof base material 1 and the tight frame 2 as the left-right direction, and the direction that corresponds to the direction perpendicular to the length direction of the tight frame 2 as the front-rear direction.

また、この長方形状の押え部材４は、外周の四辺部に直角上方へ屈曲形成された補強片15を有していると共に、前後の対向短辺部（前後両端部６の端縁）の中間部が、補強片15と反対向きに（直角下方に）屈曲形成されて、この垂下片が前記屋根下地材１の上フランジ部１Ａの一方側（前側）縁部と反対側（後側）縁部とに近接若しくは当接する位置決め片10として構成されていて、この押え部材４の前記交差中央部５を、屋根下地材１の上フランジ部１Ａ上に載置されている前記タイトフレーム２の谷部３上に上方から重ねて載置すると、前後の前記位置決め片10が上フランジ部１Ａの一方側（前側）縁部と反対側（後側）縁部とに近接若しくは当接（図３，図６参照）して、屋根下地材１（の上フランジ部１Ａ）に対し押え部材４が屋根下地材１の長さ方向と直交する前後方向へは位置ズレが防止されるように構成されている。 The rectangular pressing member 4 has reinforcing pieces 15 bent upward at right angles on the four sides of the periphery, and the middle parts of the front and rear opposing short sides (the edges of the front and rear ends 6) are bent in the opposite direction (down at right angles) to the reinforcing pieces 15, and these hanging pieces are configured as positioning pieces 10 that come into contact with or are in contact with one side (front side) edge and the opposite side (rear side) edge of the upper flange portion 1A of the roof underlayment 1. When the intersecting center portion 5 of the pressing member 4 is placed from above on the valley portion 3 of the tight frame 2 placed on the upper flange portion 1A of the roof underlayment 1, the front and rear positioning pieces 10 come into contact with or are in contact with one side (front side) edge and the opposite side (rear side) edge of the upper flange portion 1A (see Figures 3 and 6), so that the pressing member 4 is prevented from shifting position in the front-to-rear direction perpendicular to the length direction of the roof underlayment 1 relative to the roof underlayment 1 (upper flange portion 1A).

また、この押え部材４は、図１に示すように、前記交差中央部５の下面が、上方に向かって凹む形状に形成されていると共に、この凹みは、交差中央部５を前記タイトフレーム２の谷部３に上方から重ねて載置した際に谷部３に略合致する凹み形状に形成されていて、この凹みが、谷部３に対し交差中央部５（押え部材４）が位置決め状態で被嵌載置するための位置決め凹部11として構成されている（図６参照）。 As shown in FIG. 1, the lower surface of the central intersection portion 5 of the pressing member 4 is formed in a shape that is concave toward the top, and this concave shape is formed to approximately match the valley portion 3 of the tight frame 2 when the central intersection portion 5 is placed on the valley portion 3 from above, and this concave is configured as a positioning recess 11 for fitting the central intersection portion 5 (pressing member 4) in a positioned state relative to the valley portion 3 (see FIG. 6).

また、この位置決め凹部11は、前記屋根下地材１の上フランジ部１Ａ上に載置されているタイトフレーム２の谷部３に押え部材４の交差中央部５を上方から重ねて載置した際に、押え部材４の両側端部６の下面が上フランジ部１Ａ上に載置される凹設深さ寸法を有する形状に形成されている（図３，図４，図６参照）。 The positioning recess 11 is formed in a shape that has a recess depth dimension that allows the undersides of both side ends 6 of the pressing member 4 to rest on the upper flange portion 1A when the intersecting center portion 5 of the pressing member 4 is placed from above on the valley portion 3 of the tight frame 2 that is placed on the upper flange portion 1A of the roof underlayment 1 (see Figures 3, 4, and 6).

また、ここで本実施例のタイトフレーム２についてさらに詳しく説明すると、前記谷部３の上面には、その前後二箇所に上方へ向かって半球状に突出する係止凸部13が設けられている（図２参照）。 Now, to explain the tight frame 2 of this embodiment in more detail, the upper surface of the valley portion 3 is provided with two locking projections 13 that protrude upward in a semi-spherical shape at the front and rear (see Figure 2).

そして、前記押え部材４の交差中央部５には、この交差中央部５を前記タイトフレーム２の谷部３に上方から重ねて載置した際に、この谷部３上に突設されている前記係止凸部13が係止するための丸穴状の係合部12が設けられ（貫通形成され）ていて、この係止凸部13の係合部12への係合係止により、谷部３（タイトフレーム２）に対して交差中央部５（押え部材４）が水平方向に位置ズレ防止された位置決め状態となるように構成されている（図３，図６参照）。 The central intersection 5 of the pressing member 4 is provided with (formed through) a round hole-shaped engagement portion 12 for engaging with the locking protrusion 13 protruding from the valley portion 3 when the central intersection 5 is placed on top of the valley portion 3 of the tight frame 2 from above. The locking protrusion 13 engages with the engagement portion 12, so that the central intersection 5 (pressing member 4) is positioned relative to the valley portion 3 (tight frame 2) in a horizontal direction to prevent misalignment (see Figures 3 and 6).

具体的には、前記一方側端部６の上面と前記他方側端部６の上面とに、夫々の下面を上方に向かって凹となるように押圧することによって上方に向かってリング状に突出する凸条16が一体的に突設されていて、このリング凸条16内側のリング凸条16に対して凹んでいる部分が前記締付ボルト９のボルト先端の外形状に対応する平面視円形の凹部14に形成され、この円形凹部14が前記ボルト収容凹部14として構成されている（図６参照）。 Specifically, a ring-shaped protrusion 16 is integrally formed on the upper surface of the one end portion 6 and the upper surface of the other end portion 6, and the lower surface of each is pressed so that it is concave upward, forming a ring-shaped protrusion 16. The inner portion of this ring protrusion 16 that is concave relative to the ring protrusion 16 is formed into a circular recess 14 in plan view that corresponds to the outer shape of the bolt tip of the tightening bolt 9, and this circular recess 14 is configured as the bolt accommodating recess 14 (see FIG. 6).

また、本実施例の固定部材７は、前記屋根下地材１の上フランジ部１Ａとこの上フランジ部１Ａ上に載置されている前記押え部材４の端部６を上下から挟み込むようにして取付ける固定基体８に、前記押え部材４の端部６若しくはこの押え部材４の端部６が載置されている上フランジ部１Ａに締付圧接してこの押え部材４を屋根下地材１（上フランジ部１Ａ）に締付固定する前記締付ボルト９が設けられている。 The fixing member 7 in this embodiment is attached to a fixed base 8 that is attached by clamping the upper flange portion 1A of the roof underlayment 1 and the end portion 6 of the pressing member 4 placed on this upper flange portion 1A from above and below, and the tightening bolt 9 is provided to tighten and press the end portion 6 of the pressing member 4 or the upper flange portion 1A on which the end portion 6 of the pressing member 4 is placed, thereby tightening and fixing the pressing member 4 to the roof underlayment 1 (upper flange portion 1A).

また、固定基体８は、図１に示すように、一枚の金属板が折曲されて天板部17の左右両側に垂下板部18が垂下連設する正断面転コ字板状体に形成されていると共に、左右の垂下板部18は、前記屋根下地材１の上フランジ部１Ａとこの上フランジ部１Ａ上に載置されている前記押え部材４の端部６とを上下から挟み込むようにして前方及び後方から被嵌可能な被嵌用間隙19を有する側面視コ字状体（Ｃ字状体）に構成され、さらにこの被嵌用間隙19の下方に存する水平縁部が、前記上フランジ部１Ａの下面に圧接する下顎部20として構成されている。 As shown in FIG. 1, the fixed base 8 is formed by bending a single metal plate into a U-shaped plate-like body in front cross section, with hanging plate portions 18 hanging continuously on both the left and right sides of the top plate portion 17, and the left and right hanging plate portions 18 are configured as a U-shaped body (C-shaped body) in side view with a fitting gap 19 that can be fitted from the front and rear so as to sandwich the upper flange portion 1A of the roof underlayment material 1 and the end portion 6 of the pressing member 4 placed on this upper flange portion 1A from above and below, and further, the horizontal edge portion present below this fitting gap 19 is configured as a lower jaw portion 20 that presses against the underside of the upper flange portion 1A.

また、この固定基体８の天板部17には、この天板部17を上下に貫通するようにして六角ボルトが採用された前記締付ボルト９が螺着されていると共に、この締付ボルト９は、その頭部が天板部17の上方へ突出するようにして天板部17に螺着されていて、この締付ボルト９の頭部を締付操作すると、ボルト先端が天板部17から下方へ螺動進出するように構成されている。 The tightening bolt 9, which is a hexagonal bolt, is screwed into the top plate portion 17 of the fixed base 8 so as to penetrate the top plate portion 17 from top to bottom, and the tightening bolt 9 is screwed into the top plate portion 17 so that its head protrudes above the top plate portion 17. When the head of the tightening bolt 9 is tightened, the tip of the bolt is configured to screw downward from the top plate portion 17.

従って、この固定基体８を、屋根下地材１の上フランジ部１Ａとこの上フランジ部１Ａ上に載置されている前記押え部材４の端部６とを上下から挟み込むように被嵌した状態で（上フランジ部１Ａと端部６とが前記被嵌用間隙19に入り込んだ状態で）締付ボルト９を締付操作すると、螺動進出する締付ボルト９のボルト先端が前記端部６に上方から接近し、やがて端部６上面に設けられている前記ボルト収容凹部14に締付操作により収容されて圧接し、これにより上フランジ部１Ａと押え部材４の端部６とが固定部材７（固定基体８）の下顎部20と締付ボルト９によって挟み込まれ前記押え部材４が屋根下地材１（上フランジ部１Ａ）に締付固定されて、タイトフレーム２（の谷部３）が屋根下地材１上に固定されるように構成されている。 Therefore, when the fastening bolt 9 is fastened while the fixed base 8 is fitted so as to sandwich the upper flange portion 1A of the roof underlayment 1 and the end portion 6 of the pressing member 4 placed on the upper flange portion 1A from above and below (with the upper flange portion 1A and the end portion 6 entering the fitting gap 19), the bolt tip of the fastening bolt 9 that advances in a screwing motion approaches the end portion 6 from above, and is eventually accommodated and pressed into the bolt accommodating recess 14 provided on the upper surface of the end portion 6 by the fastening operation, so that the upper flange portion 1A and the end portion 6 of the pressing member 4 are sandwiched between the lower jaw portion 20 of the fixed member 7 (fixed base 8) and the fastening bolt 9, and the pressing member 4 is fastened and fixed to the roof underlayment 1 (upper flange portion 1A), and the tight frame 2 (valley portion 3) is fixed onto the roof underlayment 1.

また、本実施例では、前記押え部材４一個に対し固定部材７が二個一組（一対）で使用されるものとし、この二個の固定部材７は、その前記被嵌用間隙19の開放側を向い合せて使用される。 In addition, in this embodiment, two fixing members 7 are used in a set (pair) for each pressing member 4, and these two fixing members 7 are used with the open sides of the fitting gap 19 facing each other.
