There are two types of length L, 4985 mm and 4828 mm. The longer edge field receiver 2 is indicated by 2A in particular, and this field edge receiver 2A is schematically shown in FIG. 5 (a). Further, the shorter edge receiver 2 is indicated by 2B in particular, and this edge receiver 2B is schematically shown in FIG. 5 (b). The web 2a of the edge receiver 2A shown in FIG. 5 (a) is provided with tapping pilot holes 8 at a constant pitch p (227.5 mm) in the longitudinal direction of the web 2a. The center of the hole 8, the end face of the field edge receiver 2A, and the length n are 103.75 mm. The web 2a of the edge receiver 2B shown in FIG. 5 (b) is provided with tapping pilot holes 8 at a constant pitch p (303.3 mm) in the longitudinal direction of the web 2a. The center of 8 and the end face and length n of the field edge receiver 2B are 139.25 mm.

図６の(a) は図５の(a) に示す野縁受け２Ａの一部を実寸を基に拡大図示したものであり、図６の(b) は図５の(b) に示す野縁受け２Ｂの一部を実寸を基に拡大図示したものである。そして、各野縁受け２Ａ，２Ｂのウエブ２ａには、タッピング用の下孔８の近傍でウエブ２ａの表裏両面に対応する位置に下孔位置確認用マーク９が形成されている。この下孔位置確認用マーク９は、クリップ３の第１立板部２１に設けられたビス挿通孔６及び第２立板部２２に設けられたビス挿通孔６が前記ウエブ２ａの下孔８と合致する位置でクリップ３の左右側縁部（第１立板部２１の左右側縁部でもあるし、第２立板部２２の左右側縁部でもある）に沿うように形成された左右一対の線状部９，９からなる。 6 (a) is an enlarged view of a part of the field edge receiver 2A shown in FIG. 5 (a) based on the actual size, and FIG. 6 (b) shows the field shown in FIG. 5 (b). A part of the edge receiver 2B is enlarged and illustrated based on the actual size. In addition, in the web 2a of each of the field receivers 2A and 2B, pilot hole position confirmation marks 9 are formed at positions corresponding to both the front and back surfaces of the web 2a in the vicinity of the pilot hole 8 for tapping. The lower hole position confirmation mark 9 includes a screw insertion hole 6 provided in the first upright plate portion 21 of the clip 3 and a screw insertion hole 6 provided in the second upright plate portion 22 of the lower hole 8 of the web 2a. Left and right edge portions of the clip 3 at positions that coincide with the left and right edge portions (the left and right edge portions of the first standing plate portion 21 and the left and right edge portions of the second standing plate portion 22). It consists of a pair of linear parts 9 and 9.

この場合、クリップ３にはシングルクリップ３Ｂとダブルクリップ３Ａとの２種類があるため、左右一対の線状部９，９は、シングルクリップ３Ｂ用の左右一対の線状部９ｂ，９ｂとダブルクリップ３Ａ用の左右一対の線状部９ａ，９ａとからなるものされる。 In this case, since the clip 3 has two types of a single clip 3B and a double clip 3A, the pair of left and right linear portions 9 and 9 is a pair of left and right linear portions 9b and 9b for the single clip 3B and a double clip. It consists of a pair of left and right linear portions 9a, 9a for 3A.

上記線状部９（９ａ，９ｂ）は、図３の拡大断面図で示すように、タガネによる打ち出しによって野縁受け２のウエブ２ａの表裏両面に凹凸状を呈するように形成される。この線状部９（９ａ，９ｂ）は、タガネによる打ち出しによらず、他の方法、例えばペンキ等の塗料で線を描くことにより形成することもできるが、この実施形態のように線状部９をタガネによる打ち出しにより形成すれば、線状部９をウエブ２ａの表裏両面に同時に簡単に形成することができると共に、この線状部９は、ウエブ２ａの表裏両面に凹凸状を呈するように形成されるから、比較的離れたところからでも下孔位置確認用マークが見易くなる効果がある。 As shown in the enlarged cross-sectional view of FIG. 3, the linear portion 9 (9a, 9b) is formed so as to exhibit irregularities on both the front and back surfaces of the web 2a of the field edge receiver 2 by punching with a chisel. The linear portion 9 (9a, 9b) can be formed by drawing a line with a paint such as paint, for example, without depending on the punching, but as in this embodiment, the linear portion If 9 is formed by punching, the linear portion 9 can be easily formed on both the front and back surfaces of the web 2a at the same time, and the linear portion 9 has an uneven shape on both the front and back surfaces of the web 2a. Since it is formed, the pilot hole position confirmation mark can be easily seen even from a relatively distant place.

次に、クリップ３を野縁受け２にビス７止めする際の下孔位置確認用マーク９の作用を図６の(a) ，(b) を参照して説明する。このビス７止め作業にあたって、クリップ３（ダブルクリップ３Ａ及びシングルクリップ３Ｂ）は、第１立板部２１の下端部側の係合凸部１３，１３を野縁１（ダブル野縁１Ａ及びシングル野縁１Ｂ）のリップ部１ｏ，１ｏの裏面側に係合させると共に、第２立板部２２を図２の(c) の仮想線図示の状態から直角下向きに折り曲げて、野縁受け２に掛止した状態にしておく。 Next, the operation of the pilot hole position confirmation mark 9 when the clip 3 is fastened to the field receiver 2 with reference to the screw 7 will be described with reference to FIGS. 6 (a) and 6 (b). In this screw 7 fixing operation, the clip 3 (double clip 3A and single clip 3B) has the engaging projections 13 and 13 on the lower end side of the first standing plate portion 21 connected to the field edge 1 (double field edge 1A and single field 3). Engage with the back side of the lip portions 1o, 1o of the edge 1B) and fold the second upright plate portion 22 perpendicularly downward from the phantom line shown in FIG. Leave it stopped.

先ず、図６の(a) は野縁受け２Ａ（下孔８のピッチＰが２２７．５ｍｍ）を使用する場合であるが、この場合、野縁１がダブル野縁１Ａで、これを吊支するクリップ３がダブルクリップ３Ａであれば、図６の(a) の右側に仮想線で示すように、ダブルクリップ３Ａを野縁受け２Ａに沿って適宜にスライドさせて、このダブルクリップ３Ａの左右側縁部を、野縁受け２Ａ側の下孔位置確認用マーク９である左右一対の線状部９ａ，９ａに揃えることにより、ダブルクリップ３Ａ側のビス挿通孔６が野縁受け２Ａ側の下孔８と合致した状態となるから、野縁受け２Ａ側の下孔８の位置が作業者にとって見えにくくても、その下孔８を確認できて、ビス挿通孔６から野縁受け２Ａ側の下孔８へのタッピングビス７（図２参照）のねじ込み作業を容易迅速に行なうことができる。 First, FIG. 6A shows a case where a field edge receiver 2A (pitch P of the lower hole 8 is 227.5 mm) is used. In this case, the field edge 1 is a double field edge 1A, which is suspended. If the clip 3 to be operated is a double clip 3A, as shown by the phantom line on the right side of FIG. 6A, the double clip 3A is appropriately slid along the field receiver 2A, By aligning the side edge with a pair of left and right linear portions 9a, 9a, which are the pilot hole position confirmation marks 9 on the field edge receiver 2A side, the screw insertion hole 6 on the double clip 3A side is located on the field edge receiver 2A side. Since it is in a state of matching with the lower hole 8, even if the position of the lower hole 8 on the side edge receiving 2A side is difficult for the operator to see, the lower hole 8 can be confirmed and the screw insertion hole 6 can be seen from the side edge receiving 2A side. Easily screw in the tapping screw 7 (see Fig. 2) into the lower hole 8 It can be carried out in.

また野縁１がシングル野縁１Ｂで、これを吊支するクリップ３がシングルクリップ３Ｂあれば、図６の(a) の左側に仮想線で示すように、シングルクリップ３Ｂを野縁受け２Ａに対して適宜にスライドさせて、このシングルクリップ３Ｂの左右側縁部を、野縁受け２Ａ側の下孔位置確認用マーク９である左右一対の線状部９ｂ，９ｂに揃えることにより、シングルクリップ３Ｂ側のビス挿通孔６が野縁受け２Ｂ側の下孔８と合致した状態となって、シングルクリップ３Ｂの位置決め作業及びビス挿通孔６から野縁受け２Ｂ側の下孔８へのタッピングビス７（図３参照）のねじ込み作業を容易迅速に行なうことができる。 Further, if the field edge 1 is a single field edge 1B and the clip 3 that supports it is a single clip 3B, the single clip 3B is attached to the field edge receiver 2A as shown by a virtual line on the left side of FIG. The single clip 3B is appropriately slid to align the left and right side edges of the single clip 3B with a pair of left and right linear portions 9b and 9b which are the pilot hole position confirmation marks 9 on the field edge receiver 2A side. The screw insertion hole 6 on the 3B side is aligned with the lower hole 8 on the side edge receiver 2B side, and the positioning operation of the single clip 3B and the tapping screw from the screw insertion hole 6 to the lower hole 8 on the field edge receiver 2B side. 7 (see FIG. 3) can be easily and quickly carried out.

図６の(b) は野縁受け２Ｂ（下孔８のピッチＰが３０３．３ｍｍ）を使用する場合であり、この場合も、野縁１がシングル野縁１Ｂで、クリップ３がシングルクリップ３Ｂであれば、図６の(b) の右側に仮想線で示すように、シングルクリップ３Ｂを野縁受け２Ｂにに対して適宜にスライドさせて、このシングルクリップ３Ｂの左右側縁部を、野縁受け２Ｂ側の下孔位置確認用マーク９である左右一対の線状部９ｂ，９ｂに揃えることにより、シングルクリップ３Ｂ側のビス挿通孔６が野縁受け２Ｂ側の下孔８と合致した状態となるから、野縁受け２Ｂ側の下孔８の位置が作業者にとって見えにくくても、その下孔８を確認できて、ビス挿通孔６から野縁受け２Ｂ側の下孔８へのタッピングビス７のねじ込み作業を容易迅速に行なうことができる。また、野縁１がダブル野縁１Ａで、クリップ３がダブルクリップ３Ａの場合は、図５の(b) の左側に仮想線で示すようになる。 FIG. 6B shows a case where the field edge receiver 2B (the pitch P of the lower holes 8 is 303.3 mm) is used. In this case, the field edge 1 is a single field edge 1B and the clip 3 is a single clip 3B. Then, as shown by the phantom line on the right side of FIG. 6B, the single clip 3B is appropriately slid with respect to the field edge receiver 2B, and the left and right edges of the single clip 3B are By aligning with the pair of left and right linear portions 9b, 9b, which are the mark 9 for confirming the hole position on the edge receiving 2B side, the screw insertion hole 6 on the single clip 3B side matches the hole 8 on the side edge receiving 2B side. Therefore, even if it is difficult for the operator to see the position of the lower hole 8 on the side edge receiver 2B side, the lower hole 8 can be confirmed, and the screw insertion hole 6 can connect to the lower hole 8 on the side edge receiver 2B side. The tapping screw 7 can be screwed easily and quickly. . Further, when the field edge 1 is a double field edge 1A and the clip 3 is a double clip 3A, the left side of FIG.

この下孔位置確認用マーク９は、ウエブ２ａの表裏両面に対応する位置に形成されているから、タッピングビス７によるクリップ３（ダブルクリップ３Ａ及びシングルクリップ３Ｂ）のビス止めを、ウエブ２ａの表裏何れの面から行なう場合にも下孔８の位置を確認できる。また、クリップ３側のビス挿通孔６は、この実施形態では第１立板部２１及び第２立板部２２の夫々に設けられており、しかして例えば図２の(b) ，(c) に示すように、ダブルクリップ３Ａの第２立板部２２が野縁受け２のウエブ２ａ表面に当接する場合は、第２立板部２２側のビス挿通孔６から野縁受け２のウエブ２ａの下孔８にねじ込んで締め付ければよい。これとは逆に、ダブルクリップ３Ａの第１立板部２１が野縁受け２のウエブ２ａ表面に当接する場合は、第１立板部２１側のビス挿通孔６から野縁受け２のウエブ２ａの下孔８にねじ込んで締め付ければよい。 Since this pilot hole position confirmation mark 9 is formed at a position corresponding to both the front and back surfaces of the web 2a, the screws 3 of the clip 3 (double clip 3A and single clip 3B) with the tapping screw 7 are fastened to the front and back of the web 2a. The position of the pilot hole 8 can be confirmed in any case. Further, in this embodiment, the screw insertion hole 6 on the clip 3 side is provided in each of the first standing plate portion 21 and the second standing plate portion 22, and for example, (b) and (c) in FIG. When the second upright plate portion 22 of the double clip 3A comes into contact with the surface of the web 2a of the field receiving 2, as shown in FIG. 2, the web 2a of the field receiving 2 from the screw insertion hole 6 on the second upright plate 22 side. What is necessary is just to screw in the lower hole 8 and tighten. On the contrary, when the first upright plate portion 21 of the double clip 3A comes into contact with the surface of the web 2a of the edge receiving member 2, the web of the edge receiving member 2 is inserted from the screw insertion hole 6 on the first upright plate portion 21 side. What is necessary is just to screw and tighten to the pilot hole 8 of 2a.

上記のようにダブルクリップ３Ａ又はシングルクリップ３Ｂを野縁受け２に対しビス７止めした後、第２立板部２２の脇板部２６をダブル野縁１Ａ又はシングル野縁１Ｂの側縁部１ｂにビス２７止めすることによって、ダブルクリップ３Ａ又はシングルクリップ３Ｂをダブル野縁１Ａ又はシングル野縁１Ｂに対し強固に固定することができる。 After the double clip 3A or the single clip 3B is screwed to the field edge receiver 2 as described above, the side plate part 26 of the second upright plate part 22 is connected to the side edge part 1b of the double field edge 1A or the single field edge 1B. The double clip 3A or the single clip 3B can be firmly fixed to the double field edge 1A or the single field edge 1B.

図７は野縁受け２の端部を図６と同様に拡大図示したもので、接合すべき野縁受け２，２のウエブ２ａ，２ａの端部間に野縁受けジョイント金具１４を介装してビス１５止めするためのタッピング用の下孔１６が野縁受け２の端部に設けられていて、この下孔１６の近傍でウエブ２ａの表裏両面に対応する位置に下孔位置確認用マーク１７を形成した状態を示す。図７の(a) は野縁受け２Ａの場合を示し、図７の(b) は野縁受け２Ｂの場合を示す。 FIG. 7 is an enlarged view of the end portion of the field receiver 2 in the same manner as FIG. 6, and the field receiver joint fitting 14 is interposed between the ends of the webs 2a and 2a of the field receivers 2 and 2 to be joined.

上記下孔位置確認用マーク１７は、図８の(a) に示すように、野縁受けジョイント金具１４に設けられたビス挿通孔１８が、野縁受け２Ａ，２Ｂのウエブ２ａに設けられたタッピング用の下孔１６と合致する位置で野縁受けジョイント金具１４の端縁部１４ａ，１４ｂに沿うように延びる線状部からなるものである。 As shown in FIG. 8 (a), the lower hole position confirmation mark 17 has a screw insertion hole 18 provided in the field receiving joint fitting 14 provided in the web 2a of the field receiving 2A, 2B. It consists of a linear portion extending along the edge portions 14a and 14b of the field edge receiving joint fitting 14 at a position matching the tapping pilot hole 16.

図８の(a) ，(b) に示す野縁受けジョイント金具１４は、ウエブ１９ａと上下のフランジ１９ｂ，１９ｂとで溝形に形成され、野縁受け２Ａ，２Ｂに内嵌合可能な金具本体１９と、金具本体１９のウエブ１９ａの表面側に取り付けられたバネ鋼板製挟着板２０とからなり、挟着板２０は、その長手方向中央部がウエブ１９ａの表面側中央部に一体に取り付けられて、この取付部１９ｏを挟んでその両側部分が挟着板部２０ａ，２０ａを形成し、各挟着板部２０ａの先端部は上向きに僅かに反り返ってガイド部２０ｂを形成している。尚、図８の(a) ，(b) において、２０ｃは挟着板２０に設けられた補強リブを示し、また１４ａは金具本体１９の端縁部を示し、１４ｂは挟着板２０の端縁部を示す。前記下孔位置確認用マークである線状部１７は、ウエブ２ａに設けられた下孔１６の近傍でウエブ２ａの表裏両面に対応する位置に形成したものであるが、ウエブ２ａの表面側では金具本体１９の端縁部１４ａに平行するように位置し（図８の(a) 参照）、ウエブ２ａの裏面側では挟着板２０に平行するように位置する（図８の(b) 参照）。 The edge receiving joint fitting 14 shown in FIGS. 8 (a) and 8 (b) is formed into a groove shape with a web 19a and upper and lower flanges 19b and 19b, and can be fitted into the edge receiving 2A and 2B. It consists of a main body 19 and a spring steel plate sandwiching plate 20 attached to the surface side of the web 19a of the metal fitting body 19, and the longitudinal center portion of the sandwiching plate 20 is integrated with the center portion on the surface side of the web 19a. It is attached, and the both side portions sandwiching the attachment portion 19o form the sandwich plate portions 20a and 20a, and the tip portions of the respective sandwich plate portions 20a are slightly warped upward to form the guide portions 20b. . 8 (a) and 8 (b), 20c represents a reinforcing rib provided on the sandwiching plate 20, 14a represents an edge of the metal fitting body 19, and 14b represents an end of the sandwiching plate 20. The edges are shown. The linear portion 17 serving as a mark for confirming the lower hole position is formed at a position corresponding to both the front and back surfaces of the web 2a in the vicinity of the lower hole 16 provided in the web 2a. It is positioned so as to be parallel to the end edge portion 14a of the metal fitting body 19 (see FIG. 8A), and is positioned so as to be parallel to the sandwiching plate 20 on the back surface side of the web 2a (see FIG. 8B). ).

従って、野縁受け２を端部どうし接続する時は、図８の(a) ，(b) に示すように、金具本体１９の両端部側を両野縁受け２，２の端部に内嵌合すると共に、両野縁受け２，２の端部を金具本体１９の両挟着板部２０ａ，２０ａと両野縁受け２Ａ，２Ｂのウエブ２ａ，２ａとの間に差し込んだ状態とし、斯かる状態から図８の(a) に示すように、タッピングビス１５を野縁受けジョイント金具１４側に設けられたビス挿通孔１８から野縁受け２，２のウエブ２ａ側のタッピング用の下孔１６（図７参照）にねじ込んで締め付けることによって、両野縁受け２，２を一体的に接続することができる。 Therefore, when connecting the edge receivers 2 to each other, as shown in FIGS. 8 (a) and 8 (b), both ends of the metal fitting body 19 are connected to the ends of both edge receivers 2 and 2, respectively. In addition to fitting, the ends of the two edge receivers 2, 2 are inserted between the sandwiching plate portions 20a, 20a of the metal fitting body 19 and the webs 2a, 2a of the two edge receivers 2A, 2B, From this state, as shown in FIG. 8 (a), the tapping screw 15 is moved from the screw insertion hole 18 provided on the edge receiving joint fitting 14 side to the bottom edge tapping screw 18 on the web 2a side of the edge receiving 2 and 2. By screwing and tightening into the hole 16 (see FIG. 7), the two edge receivers 2 and 2 can be integrally connected.

上記のように野縁受け２を端部どうし接続する際に、野縁受け２の端部に、下孔１６の近傍でウエブ２ａの表裏両面に対応する位置に下孔位置確認用マークである線状部１７が形成してあるため、野縁受けジョイント金具１４を野縁受け２の端部に対し嵌合させる時に、金具本体１９の端縁部１４ａ又は挟着板２０の端縁部１４ｂを、図８の(a) ，(b) に示すように、野縁受け２側の下孔位置確認用マークとしての線状部１７に平行に揃えることによって、野縁受けジョイント金具１４のビス挿通孔１８が野縁受け２側の下孔１６と合致した状態となり、従って野縁受け２側の下孔１６の位置が作業者にとって見えにくい状態にあっても、その下孔１６を確認できて、ビス挿通孔１８から野縁受け２側の下孔１６へのタッピングビス１５のねじ込み作業を容易迅速に行なうことができる。 When the edge receiver 2 is connected to each other as described above, a pilot hole position confirmation mark is provided at the end of the field receiver 2 at positions corresponding to both the front and back surfaces of the web 2a in the vicinity of the lower hole 16. Since the linear portion 17 is formed, when the edge receiving joint fitting 14 is fitted to the end of the field receiving 2, the edge 14 a of the fitting body 19 or the edge 14 b of the sandwiching plate 20 is used. As shown in FIGS. 8 (a) and 8 (b), the screws of the field receiving joint fitting 14 are aligned in parallel with the linear portion 17 as a mark for confirming the hole position on the field edge receiving 2 side. Even if the insertion hole 18 is aligned with the lower hole 16 on the side edge receiver 2 side, and therefore the position of the lower hole 16 on the field edge receiver 2 side is difficult to see for the operator, the lower hole 16 can be confirmed. The screw of the tapping screw 15 from the screw insertion hole 18 to the lower hole 16 on the side edge receiver 2 side It can be carried out only work easily quickly.

前記下孔位置確認用マークとしての線状部１７は、図示は省略するが、図４に示す下孔位置確認用マークである線状部９と同様に、タガネによる打ち出しによって前記ウエブの表裏両面に形成されたものである。このように線状部１７をタガネによる打ち出しにより形成すれば、線状部１７をウエブ２ａの表裏両面に同時に簡単に形成することができる。この線状部１７は、タガネによる打ち出しによらず、他の方法、例えばペンキ等の塗料で線を描くことにより形成することもできるが、この実施形態のように線状部１７をタガネによる打ち出しにより形成すれば、線状部１７をウエブ２ａの表裏両面に同時に簡単に形成することができると共に、この線状部１７は、ウエブ２ａの表裏両面に凹凸状を呈するように形成されるから、比較的離れたところからでも下孔位置確認用マークが見易くなる効果がある。 Although the illustration of the linear portion 17 as the pilot hole position confirmation mark is omitted, similar to the linear portion 9 which is the pilot hole position confirmation mark shown in FIG. It is formed. If the linear portion 17 is formed by punching in this way, the linear portion 17 can be easily formed simultaneously on both the front and back surfaces of the web 2a. The linear portion 17 can be formed by drawing a line with other methods, for example, a paint such as paint, instead of punching with a chisel. However, as in this embodiment, the linear portion 17 is punched with a chisel. Since the linear portion 17 can be easily and simultaneously formed on both the front and back surfaces of the web 2a, the linear portion 17 is formed so as to have irregularities on the front and back surfaces of the web 2a. There is an effect that the pilot hole position confirmation mark can be easily seen even from a relatively distant place.
