Description

本発明は、野縁受けに野縁を結合するためのクリップに関する。 The present invention relates to a clip for joining a field edge to a field edge receiver.

鉄筋コンクリート造の建築構造物において、コンクリート等からなる天井に複数の長尺形状の野縁受けを水平方向に延在するようにアンカーボルトによって吊り下げ、野縁受けの下方に複数の長尺形状の野縁を水平方向かつ野縁受けに対して直交するように結合し、野縁に内装材としての天井パネルを結合したものがある。野縁受けは、断面コ字状のチャンネル材が使用されることがある。野縁は、底壁部と、底壁部の両側縁から上方へと立ち起こされた一対の側壁部と、側壁部の上縁から互いに近接する方向に延出したリップ部とを有し、リップ部の先端が底壁部側に屈曲し、リップ部の底壁部側にリップ溝を形成し、一対のリップ部間に開口部を形成しているものがある。このような天井構造体において、野縁受けに野縁を結合するために、金属製のクリップが使用されることがある（例えば、特許文献１）。 In a reinforced concrete building structure, a plurality of long-shaped field edge receivers are suspended from a ceiling made of concrete or the like by an anchor bolt so as to extend horizontally, and a plurality of long-shaped field edge supports are formed below the field edge receiver. There is a type in which the field edge is connected in a horizontal direction and perpendicular to the field edge receiver, and a ceiling panel as an interior material is connected to the field edge. A channel material having a U-shaped cross section may be used for the field edge receiver. The field edge has a bottom wall part, a pair of side wall parts raised upward from both side edges of the bottom wall part, and a lip part extending in a direction close to each other from the upper edge of the side wall part, In some cases, the tip of the lip portion is bent toward the bottom wall portion, a lip groove is formed on the bottom wall portion side of the lip portion, and an opening is formed between the pair of lip portions. In such a ceiling structure, a metal clip may be used to join the field edge to the field edge receiver (for example, Patent Document 1).

特許文献１に係るクリップは、鞍形金具（交差連結金具）と締め付けねじとを有する。鞍形金具は、ねじ穴を有する上面板と、上面板の互いに対角位置の側縁から下方に延在する２つの側板とを備える。クリップの上下方向の中心軸に対して、両側板は互いに１８０°回転対称な形状であり、その下部に切欠を有する。このクリップを野縁受けと野縁とに取り付けるには、まず、鞍形金具を野縁受けに上から跨がせ、次に、鞍形金具を傾斜させて両側板の下端を野縁内に突入させた後回転させることで、切欠に野縁のリップ部を受容させる。そして、締め付けねじをねじ穴に螺入させて、鞍形金具を引き上げ、締め付けねじの先端と切欠の下縁との間に野縁受けの上横壁部と野縁のリップ部とが挟持され、野縁受け及び野縁が結合される。 The clip according to Patent Document 1 has a hook-shaped bracket (cross-connecting bracket) and a fastening screw. The saddle-shaped metal fitting includes an upper surface plate having a screw hole and two side plates extending downward from side edges of the upper surface plate that are diagonal to each other. Both side plates are 180 ° rotationally symmetric with respect to the center axis in the vertical direction of the clip, and have a notch in the lower part thereof. To attach this clip to the field edge and the field edge, first place the saddle-shaped bracket over the field edge receiver, and then tilt the saddle-shaped bracket so that the lower ends of both side plates are within the field edge. By rotating after entering, the lip of the field edge is received in the notch. Then, the tightening screw is screwed into the screw hole, the saddle-shaped bracket is pulled up, and the upper lateral wall portion of the field edge receiver and the lip portion of the field edge are sandwiched between the tip of the tightening screw and the lower edge of the notch, The field edge and the field edge are combined.

しかしながら、特許文献１に係るクリップは、野縁受けの上部にダクト等の設備が設置されている場合には、締め付けねじを締め付けるための作業スペースを十分にとることができないという問題があった。また、側板の下部をリップ部間に挿入できるようにするために、側板を２つにして互いに野縁受けを跨いで対角上に配置させている。このため、結合構造のバランスが悪く、結合安定性を高めることができなかった。例えば、地震等によって野縁受け及び野縁に水平方向の荷重が加わると、互いに上下方向の軸に対して回転し、野縁受けと野縁との結合が解除されるおそれがあった。 However, the clip according to Patent Document 1 has a problem in that a work space for tightening a tightening screw cannot be sufficiently taken when a facility such as a duct is installed on the upper portion of the field receiver. Further, in order to allow the lower portion of the side plate to be inserted between the lip portions, the two side plates are arranged in a diagonal manner across the edge receiver. For this reason, the balance of the bonding structure was poor, and the bonding stability could not be improved. For example, when a horizontal load is applied to the field receiver and the field edge due to an earthquake or the like, they may rotate with respect to the vertical axis and the connection between the field receiver and the field edge may be released.

本発明は、以上の背景を鑑みてなされたものであって、野縁受けに野縁を取り付けるためのクリップの取付作業性及び結合安定性を向上させることを課題とする。 This invention is made | formed in view of the above background, Comprising: It makes it a subject to improve the attachment workability | operativity and coupling | bonding stability of the clip for attaching a field edge to a field edge receiver.

以下、図面を参照して、本発明を適用した野縁受けと野縁とを結合するクリップの実施形態を詳細に説明する。以下の説明では、各図に示す座標軸に基づいて各方位を定める。 Hereinafter, with reference to the drawings, an embodiment of a clip for joining a field edge receiver and a field edge to which the present invention is applied will be described in detail. In the following description, each direction is determined based on the coordinate axes shown in the drawings.

図１に示すように、クリップ１は、野縁受け３と野縁４とを結合するために使用される。野縁受け３及び野縁４は、例えば亜鉛めっき鋼板やアルミ板から形成された長尺部材である。野縁受け３は、断面形状において、上下方向に延びる縦壁部６と、縦壁部６の上端縁及び下端縁から縦壁部６に対して直角かつ同じ方向（前方）に突出する上横壁部７及び下横壁部８とを有する（いわゆる、軽溝形鋼）。野縁４は、断面形状において、左右方向（野縁４の幅方向）に延びる底壁部１１と、底壁部１１の両端から底壁部１１に対して直角かつ同じ方向（上方）に突出する一対の側壁部１２と、一対の側壁部１２の各上端から互いに近接する方向に突出した一対のリップ部１３とを有している（いわゆる、リップ溝形鋼）。リップ部１３の先端は、底壁部１１側に直角に折り曲げられている。これにより、リップ部１３の底壁部１１側を向く部分には、底壁部１１と相反する側（上方）に窪んだリップ溝１４が形成されている。 As shown in FIG. 1, the clip 1 is used to connect the field edge receiver 3 and the field edge 4. The field edge receiver 3 and the field edge 4 are long members formed of, for example, a galvanized steel sheet or an aluminum sheet. In the cross-sectional shape, the field edge receiver 3 has a vertical wall portion 6 that extends in the vertical direction, and an upper horizontal wall that protrudes in the same direction (forward) from the upper and lower edges of the vertical wall portion 6 at a right angle to the vertical wall portion 6. It has a part 7 and a lower lateral wall part 8 (so-called light grooved steel). In the cross-sectional shape, the field edge 4 has a bottom wall portion 11 extending in the left-right direction (the width direction of the field edge 4), and projects from both ends of the bottom wall portion 11 at a right angle to the bottom wall portion 11 and in the same direction (upward). A pair of side wall portions 12 and a pair of lip portions 13 projecting from the respective upper ends of the pair of side wall portions 12 in directions close to each other (so-called lip channel steel). The tip of the lip 13 is bent at a right angle toward the bottom wall 11. Accordingly, a lip groove 14 that is recessed on the side (upward) opposite to the bottom wall portion 11 is formed in a portion facing the bottom wall portion 11 side of the lip portion 13.

コンクリートや鉄骨等から形成された建築構造体の天井又は梁である躯体天井部１５には、上下に延在するアンカーボルト１６の上端が結合されている。アンカーボルト１６の下端には、野縁受けホルダ１７が結合されている。野縁受けホルダ１７は、一端においてアンカーボルト１６に締結され、他端に野縁受け３を下方から包み込み、支持するフック部を備えている。アンカーボルト１６及び野縁受けホルダ１７は、１つの野縁受け３に対して複数設けられ、野縁受け３を適所で支持している。野縁受け３は、複数設けられ、それぞれが１つの水平面上に配置されている。本実施形態では、各野縁受け３の軸線（長手方向）が左右方向に延在している。 An upper end of an anchor bolt 16 extending in the vertical direction is coupled to a frame ceiling portion 15 which is a ceiling or beam of a building structure formed of concrete, steel frame, or the like. A field edge holder 17 is coupled to the lower end of the anchor bolt 16. The field edge holder 17 is fastened to the anchor bolt 16 at one end, and includes a hook portion that wraps and supports the field edge receiver 3 from below at the other end. A plurality of anchor bolts 16 and field edge holders 17 are provided for one field edge receiver 3, and support the field edge receiver 3 in place. A plurality of field edge receivers 3 are provided, each of which is arranged on one horizontal plane. In the present embodiment, the axis (longitudinal direction) of each field receiver 3 extends in the left-right direction.

野縁４は、複数設けられ、野縁受け３の下方において、それぞれが１つの水平面上に配置されている。本実施形態では、各野縁４の軸線（長手方向）が前後方向に延在している。すなわち、野縁４は、野縁受け３に対して直交するように配置され、上方から見て野縁受け３と共に格子形状を形成している。野縁４は、上方から見て野縁受け３と交差する箇所において、クリップ１によって野縁受け３に結合されている。野縁４の底壁部１１の下面には、例えばビスにより天井パネル１９が取り付けられている。野縁受け３及び野縁４は、延在する方向を長手方向、長手方向に直交する水平方向を幅方向（短手方向）とする。 A plurality of field edges 4 are provided, and each of the field edges 4 is disposed on one horizontal plane below the field edge receiver 3. In the present embodiment, the axis (longitudinal direction) of each field edge 4 extends in the front-rear direction. That is, the field edge 4 is disposed so as to be orthogonal to the field edge receiver 3 and forms a lattice shape together with the field edge receiver 3 as viewed from above. The field edge 4 is coupled to the field edge receiver 3 by the clip 1 at a location where the field edge 4 intersects with the field edge receiver 3 as viewed from above. A ceiling panel 19 is attached to the lower surface of the bottom wall portion 11 of the field edge 4 by screws, for example. In the field edge receiver 3 and the field edge 4, the extending direction is the longitudinal direction, and the horizontal direction orthogonal to the longitudinal direction is the width direction (short direction).

図２に示すように、クリップ１は、クリップ部材２１とボルト（ねじ部材）２２とを有する。 As shown in FIG. 2, the clip 1 includes a clip member 21 and a bolt (screw member) 22.

クリップ部材２１は、上壁２３と、前壁２４と、下壁２５と、後壁２６とを備える。本実施形態では、クリップ部材２１は、１枚の金属板をフォーミング加工（曲げ加工、プレス加工）することによって形成されている。金属板は、例えば、冷間圧延鋼板やステンレス板等であってよい。クリップ部材２１にばね性を持たせるため、焼入れ等の熱処理を行うことが好ましい。なお、他の実施形態では、クリップ部材２１は、樹脂の成形品であってもよい。 The clip member 21 includes an upper wall 23, a front wall 24, a lower wall 25, and a rear wall 26. In this embodiment, the clip member 21 is formed by forming (bending or pressing) a single metal plate. The metal plate may be, for example, a cold rolled steel plate or a stainless steel plate. In order to give the clip member 21 springiness, it is preferable to perform a heat treatment such as quenching. In other embodiments, the clip member 21 may be a resin molded product.

上壁２３は、ねじ孔２７を有する本体部２８と、本体部２８の左右両側端から下方に延出する一対の突片２９とを備える。本体部２８は、略長方形を呈する平板状の部分であり、結合状態においては、後方に進むにつれて上方に進むように延在している。すなわち、本体部２８は、その前端が後端より下方に位置するように野縁受け３の下横壁部８に対して上下方向に傾斜している。ねじ孔２７は、その軸線が本体部２８の主面に直交するように設けられている。また、左右各々の突片２９は、互いに左右対称な形状であり、主面が左右を向いた平板状を呈する。突片２９は、側面視で略直角三角形状を呈し、本体部２８との境界をなす稜線となる斜辺と、上下方向に延びる後縁と、前後方向に延びる下縁とを有する。上壁２３の前後方向の距離は、野縁受け３の下横壁部８の前後方向の長さに略一致する。 The upper wall 23 includes a main body portion 28 having a screw hole 27 and a pair of projecting pieces 29 extending downward from both left and right ends of the main body portion 28.

As for the main-body part 30, the main surface has faced up and down. The pair of locking pieces 31 are symmetrical to each other, have a substantially square shape in a side view, and have upper end edges extending in the front-rear direction. In the present embodiment, the pair of locking pieces 31 are inclined in the left-right direction so as to be separated from each other as they proceed upward. The width in the left-right direction of the lower wall 25, that is, the distance between the upper ends of the pair of locking pieces 31 is longer than the distance between the pair of lip portions 13 and is equal to or less than the distance between the inner surfaces of the pair of left and right side wall portions 12. Each of the upper ends of the locking pieces 31 can be simultaneously locked in the left and right lip grooves 14. The length of the lower wall 25 in the front-rear direction, that is, the length of the main body 30 in the front-rear direction is equal to or less than the distance between the pair of lip portions 13.

後壁２６は、下壁２５の後端から上方に延出する平板状の部分であり、主面が前後を向いている。後壁２６の上端は、係止片３１の上端よりも上方に位置し、突片２９の下端よりも下方に位置する。後壁２６の上下方向の長さは、側壁部１２の上端から底壁部１１の上面までの距離以下である。後壁２６の左右方向の幅は、一対のリップ部１３間の距離以下である。また、前壁２４の前面と後壁２６の後面との距離は、一対のリップ部１３間の距離以下である。また、前壁２４の後面と後壁２６の前面との距離は、野縁受け３の下横壁部８の前端と縦壁部６の後面との距離以上とする必要があり、本実施形態では、両者の距離は略等しい（図４及び図５参照）。 The rear wall 26 is a flat portion extending upward from the rear end of the lower wall 25, and the main surface faces front and rear. The upper end of the rear wall 26 is located above the upper end of the locking piece 31 and is located below the lower end of the protruding piece 29. The length of the rear wall 26 in the vertical direction is equal to or shorter than the distance from the upper end of the side wall portion 12 to the upper surface of the bottom wall portion 11. The width in the left-right direction of the rear wall 26 is equal to or less than the distance between the pair of lip portions 13. The distance between the front surface of the front wall 24 and the rear surface of the rear wall 26 is equal to or less than the distance between the pair of lip portions 13. Further, the distance between the rear surface of the front wall 24 and the front surface of the rear wall 26 needs to be equal to or greater than the distance between the front end of the lower horizontal wall portion 8 of the field receiver 3 and the rear surface of the vertical wall portion 6. The distance between them is substantially equal (see FIGS. 4 and 5).

ボルト２２は、ねじ孔２７に螺合するねじ山を有する軸部と軸部の基端に設けられた頭部とを備える。ボルト２２の先端は、平坦な形状となっている。 The bolt 22 includes a shaft portion having a screw thread that is screwed into the screw hole 27 and a head portion provided at a proximal end of the shaft portion. The tip of the bolt 22 has a flat shape.

次に、図３〜図５を参照して、クリップ１による野縁受け３と野縁４との結合手順について説明する。最初に、クリップ１は、上壁２３が上側、下壁２５が下側になるように、野縁受け３と野縁４とが交差する部分の野縁受け３の前側に配置され、上方からねじ孔２７にボルト２２の先端側が螺入された状態にある。 Next, with reference to FIGS. 3 to 5, a procedure for joining the field edge receiver 3 and the field edge 4 by the clip 1 will be described. First, the clip 1 is disposed on the front side of the field edge receiver 3 where the field edge receiver 3 and the field edge 4 intersect so that the upper wall 23 is on the upper side and the lower wall 25 is on the lower side. The tip end side of the bolt 22 is screwed into the screw hole 27.

そして、クリップ１は、その幅方向（結合状態における左右方向）が前後に延在するように配置される。前壁２４の前面と後壁２６の後面との距離は、一対のリップ部１３間の距離以下であるため、クリップ１の下側は、野縁４の内部へと進入可能である。そこで、図３に示すように、クリップ１の下側を一対のリップ部１３間を通過させて、少なくとも後壁２６が完全に野縁４の内部に受容されるまで、クリップ１を下方に移動させる。 And the clip 1 is arrange | positioned so that the width direction (left-right direction in a coupling | bonding state) may extend back and forth. Since the distance between the front surface of the front wall 24 and the rear surface of the rear wall 26 is equal to or less than the distance between the pair of lip portions 13, the lower side of the clip 1 can enter the inside of the field edge 4. Therefore, as shown in FIG. 3, the lower side of the clip 1 is passed between the pair of lip portions 13, and the clip 1 is moved downward until at least the rear wall 26 is completely received inside the field edge 4. Let

次に、図４に示すように、前壁２４が後壁２６に対して前方に来るように、クリップ１を９０°回転させる。その後、後壁２６が野縁受け３の下方を通過して野縁受け３の後方に配置され、前壁２４の後面が下横壁部８の前端に当接するまで、クリップ１を後方に移動させる。この時、突片２９の下縁を下横壁部８の上面に当接させ、突片２９の後縁を縦壁部６の前面に当接させる。これにより、この段階におけるクリップ１の位置が安定する。 Next, as shown in FIG. 4, the clip 1 is rotated by 90 ° so that the front wall 24 comes forward with respect to the rear wall 26. Thereafter, the clip 1 is moved backward until the rear wall 26 passes below the field receiver 3 and is disposed behind the field receiver 3 and the rear surface of the front wall 24 abuts the front end of the lower lateral wall 8. . At this time, the lower edge of the projecting piece 29 is brought into contact with the upper surface of the lower horizontal wall portion 8, and the rear edge of the projecting piece 29 is brought into contact with the front surface of the vertical wall portion 6. Thereby, the position of the clip 1 at this stage is stabilized.

そして、ねじ孔２７にボルト２２を螺進させて、ボルト２２の先端を下横壁部８の上面に当接させる。この状態から、さらにボルト２２を螺進させると、ボルト２２の先端が下横壁部８の上面を後方に向かって摺動するとともに、クリップ部材２１が上方に移動する。この時、突片２９の後縁は、クリップ部材２１が上昇するためのガイドとして機能する。また、前壁２４の後面は下横壁部８の前端に摺接し、後壁２６の前面は縦壁部６の後面に摺接する。 Then, the bolt 22 is screwed into the screw hole 27 and the tip of the bolt 22 is brought into contact with the upper surface of the lower horizontal wall portion 8. When the bolt 22 is further screwed from this state, the tip of the bolt 22 slides backward on the upper surface of the lower lateral wall portion 8 and the clip member 21 moves upward. At this time, the rear edge of the protruding piece 29 functions as a guide for the clip member 21 to rise. Further, the rear surface of the front wall 24 is in sliding contact with the front end of the lower horizontal wall portion 8, and the front surface of the rear wall 26 is in sliding contact with the rear surface of the vertical wall portion 6.

そして、図５に示すように、係止片３１の先端がリップ溝１４に係止されるまでボルト２２を螺進させることによって、野縁受け３と野縁４とが結合する。この時、ボルト２２の先端が下横壁部８の上面だけではなく、縦壁部６の前面にも当接していることが好ましい。 Then, as shown in FIG. 5, the field receiver 3 and the field edge 4 are joined by screwing the bolt 22 until the tip of the locking piece 31 is locked in the lip groove 14. At this time, it is preferable that the tip of the bolt 22 is in contact with not only the upper surface of the lower horizontal wall portion 8 but also the front surface of the vertical wall portion 6.

すると、下横壁部８とリップ部１３とがボルト２２の先端と係止片３１の先端とに挟持されることにより、野縁受け３と野縁４との上下方向の相対的な移動が規制され、摩擦力によって前後・左右方向への移動も抑制される。また、下壁２５によって連結された前壁２４と後壁２６とが、野縁受け３を挟持するため、クリップ１が野縁受け３に対して前後方向に移動することが規制される。また、一対の係止片３１の各々が一対のリップ溝１４の各々に係止され、かつ前壁２４の下部の両側縁が一対のリップ部１３に挟持されているため、クリップ１が野縁４に対して左右方向に移動することが規制される。このように、クリップ１による水平方向の摩擦力に逆らう荷重が加えられても、クリップ１は、野縁受け３及び野縁４のそれぞれから外れ難いため、野縁受け３と野縁４との結合安定性を高めることができる。 Then, the lower horizontal wall portion 8 and the lip portion 13 are sandwiched between the tip end of the bolt 22 and the tip end of the locking piece 31, thereby restricting the relative movement in the vertical direction between the field edge receiver 3 and the field edge 4. In addition, movement in the front-rear and left-right directions is also suppressed by the frictional force. Further, since the front wall 24 and the rear wall 26 connected by the lower wall 25 sandwich the field receiver 3, the clip 1 is restricted from moving in the front-rear direction with respect to the field receiver 3. Further, since each of the pair of locking pieces 31 is locked to each of the pair of lip grooves 14 and both side edges of the lower portion of the front wall 24 are sandwiched between the pair of lip portions 13, the clip 1 has a field edge. 4 is restricted from moving in the left-right direction. Thus, even if a load against the horizontal frictional force by the clip 1 is applied, the clip 1 is difficult to come off from each of the field edge receiver 3 and the field edge 4. Bond stability can be increased.

また、クリップ１は、野縁受け３の側方から、野縁受け３の下方を跨ぐように取り付けられるため、野縁受け３の上方にダクト等の設備が設置されていても、それらの設備は取付作業の障害とはならない。また、ボルト２２の頭部が縦壁部６及び上横壁部７から離れるようにねじ孔２７が形成されているため、上横壁部７は、ボルト２２を螺進させるためのドライバー等の工具を使用する際の障害にならない。また、クリップ１を構成する部品が、クリップ部材２１とボルト２２との２つから構成される簡素な構造であるため、低コストで製造できるとともに、取付作業が簡略になっている。 Further, since the clip 1 is attached from the side of the field edge receiver 3 so as to straddle the area below the field edge receiver 3, even if a facility such as a duct is installed above the field edge receiver 3, those facilities are provided. Does not hinder the installation work. Further, since the screw hole 27 is formed so that the head of the bolt 22 is separated from the vertical wall portion 6 and the upper horizontal wall portion 7, the upper horizontal wall portion 7 uses a tool such as a screwdriver for screwing the bolt 22. Does not become an obstacle to use. Moreover, since the components which comprise the clip 1 are the simple structures comprised from two of the clip member 21 and the volt | bolt 22, while being able to manufacture at low cost, the attachment operation is simplified.

次に、図６を参照して、本発明の変形実施形態について説明する。変形実施形態に係るクリップ４０は、下壁４２と前壁２４及び後壁２６との結合部の形状がクリップ１と異なる。クリップ４０において、クリップ１と同様の構成は、同一の符号を付して説明を省略する。 Next, a modified embodiment of the present invention will be described with reference to FIG. The clip 40 according to the modified embodiment is different from the clip 1 in the shape of the connecting portion between the lower wall 42 and the front wall 24 and the rear wall 26. In the clip 40, the same configurations as those of the clip 1 are denoted by the same reference numerals and description thereof is omitted.

変形実施形態に係るクリップ部材４１の下壁４２は、前壁２４の下端から、後方に進むにつれて下方に進むように傾斜して延在する前端傾斜部４３と、前端傾斜部４３の後端から後方に延在する本体部４４と、本体部４４の後端から後方に進むにつれて上方に進むように傾斜して延在する後端傾斜部４５と、本体部４４の左右両側端から各々略上方に延出する一対の係止片３１とを備える。前端傾斜部４３及び後端傾斜部４５は、クリップ４０の下側を一対のリップ部１３間に通すための誘い形状となっており、この作業を容易にする。 The lower wall 42 of the clip member 41 according to the modified embodiment extends from the lower end of the front wall 24 from the front end inclined portion 43 that extends so as to advance downward as it goes backward, and from the rear end of the front end inclined portion 43. A main body portion 44 extending rearward, a rear end inclined portion 45 extending obliquely so as to advance upward from the rear end of the main body portion 44, and substantially upward from both left and right side ends of the main body portion 44. And a pair of locking pieces 31 extending in the direction. The front end inclined portion 43 and the rear end inclined portion 45 have an invitation shape for passing the lower side of the clip 40 between the pair of lip portions 13, and facilitate this operation.

以上で具体的実施形態の説明を終えるが、本発明は上記実施形態に限定されることなく幅広く変形実施することができる。例えば、後壁２６の上端側を後傾させて、クリップ部材２１を引き上げるときの誘い形状としてもよい。また、ボルト２２の先端を丸みを帯びた形状にしてもよく、又はボルト２２の先端の円周状の縁部を面取りしてもよい。例えば、ボルト２２の軸線と面取り面とのなす角度は、ねじ孔２７の軸線と下横壁部８とがなす角度に一致させてもよい。また、後壁２６、突片２９及び係止片３１の全て又はいずれかを省略しても、野縁受け３と野縁４とを結合させることができる。また、ねじ孔２７の軸線が横下壁部８に対して前傾していれば、上壁２３は傾斜していなくともよい。例えば、上壁２３を、水平にしたり、前壁２３と平行にしてもよい。 Although the description of the specific embodiment is finished as described above, the present invention is not limited to the above embodiment and can be widely modified. For example, it is good also as an invitation shape when the upper end side of the rear wall 26 is inclined backwards and the clip member 21 is pulled up. Further, the tip of the bolt 22 may be rounded, or the circumferential edge of the tip of the bolt 22 may be chamfered. For example, the angle formed between the axis of the bolt 22 and the chamfered surface may match the angle formed between the axis of the screw hole 27 and the lower horizontal wall portion 8. Even if all or any of the rear wall 26, the projecting piece 29, and the locking piece 31 is omitted, the field edge receiver 3 and the field edge 4 can be combined. If the axis of the screw hole 27 is inclined forward with respect to the lateral lower wall portion 8, the upper wall 23 may not be inclined. For example, the upper wall 23 may be horizontal or parallel to the front wall 23.
