【産業上の利用分野】[Industrial applications]

この考案は、例えば、屋根材の固定のため、Ｈ鋼等からなる梁材上に固定する ようなタイトフレームに関する。 The present invention relates to a tight frame which is fixed on a beam made of H steel or the like for fixing a roofing material, for example.

【０００２】[0002]

【従来の技術】[Prior art]

タイトフレームは通常、下端に支持脚が形成され、梁材に対してはこの支持脚 を溶接することによって固定している。 A tight frame usually has a support leg formed at the lower end, and is fixed to the beam by welding the support leg.

【０００３】 しかし、溶接によって固定するのでは、固定作業が煩雑で作業性が悪く、その うえ、タイトフレームは所定間隔おきに固定する必要があるため、固定位置を間 違えた場合などやり直しが利かず、作業全体が作業者に負担をかけるものである 。However, if fixing by welding, the fixing work is complicated and the workability is poor. Moreover, since the tight frame needs to be fixed at predetermined intervals, it is easy to redo it if the fixing position is wrong. Instead, the whole work puts a strain on the worker.

【０００４】 そこで、溶接をせずとも固定作業が行なえるタイトフレームが案出された。こ れは梁材としてのＨ鋼をその幅方向で挟持するもので、Ｈ鋼の幅方向に分割した ２つの部材には、Ｈ鋼の縁部の厚みに対応する係止部を形成し、これら２つの部 材をボルトナットで緊結する構成を採用している。Therefore, a tight frame has been devised which can be fixed without welding. This is to clamp the H steel as a beam material in the width direction, and two members divided in the width direction of the H steel are formed with a locking portion corresponding to the thickness of the edge of the H steel, We have adopted a structure in which these two parts are tightly connected with bolts and nuts.

【０００５】[0005]

【考案が解決しようとする課題】[Problems to be solved by the device]

しかしＨ鋼には、建物の規模等に応じて様々なサイズのものを使用するため、 上述したような構成のタイトフレームの場合には、係止部の大きさが異なるもの をＨ鋼に合せて各種用意しなければ固定作業の行なえない場合があった。 However, since H steels of various sizes are used depending on the scale of the building, in the case of the tight frame having the above-mentioned configuration, the ones with different locking portions should be matched with H steels. In some cases, fixed work could not be performed unless various types were prepared.

【０００６】 そこでこの考案は、どのような大きさのＨ鋼にも溶接作業なしで固定できるよ うなタイトフレームの提供を目的とする。[0006] Therefore, an object of the present invention is to provide a tight frame that can be fixed to H steel of any size without welding work.

【課題を解決するための手段】 上述した課題を解決するための手段を実施例の図３を用いて説明すると、その 構成は、本体２下部の固定部４を梁材３の被固定部３ａに固定するとともに、本 体２上部に屋根材を固定するタイトフレーム１であって、前記固定部４を、前記 被固定部３ａ上に載置する上部材１６と、該上部材１６の下側位置に相対向して 保持する２つの下部材ｚ１７，１７とで構成し、これら上部材１６と下部材１７ ，１７との間に、対向する上記下部材１７，１７間の間隔を前記被固定部３ａの 幅寸法に合せて変更する幅変更機構を設け、上記下部材１７，１７の後端部に、 支持突起２６，２６を立設して上記上部材１６に対する回動支点を設けるととも に、先端部に圧接部２７，２７を形成し、上記上部材１６と２つの下部材１７， １７との相互間に、両者を緊結して前記被固定部３ａの幅方向における両側縁に 対し挟持固定する緊結手段２９，３０，３１，３２を設けたタイトフレーム１で あることを特徴とする。[Means for Solving the Problems] Means for solving the above-mentioned problems will be described with reference to FIG. 3 of an embodiment. A tight frame 1 for fixing the roofing material to the upper part of the main body 2 as well as the upper member 16 for mounting the fixing portion 4 on the fixed portion 3a, and a lower side of the upper member 16. It is composed of two lower members z17, 17 which are held opposite to each other in position, and the space between the lower members 17, 17 facing each other is fixed between the upper member 16 and the lower members 17, 17. A width changing mechanism for changing the width of the portion 3a is provided, and at the rear end portions of the lower members 17 and 17, support protrusions 26 and 26 are provided upright to provide a rotation fulcrum for the upper member 16. In addition, the pressure contact portions 27, 27 are formed at the tip end, and the upper member 16 and two The tight frame 1 is provided with binding means 29, 30, 31, 32 for tightly binding the lower members 17, 17 to both side edges in the width direction of the fixed portion 3a and tightly binding them. Is characterized by.

【作用】[Action]

すなわち、上述の構成によれば、梁材に対する固定は、まず、固定部を構成す る上部材を梁材の被固定部に載置するとともに、対向する下部材同士の間隔を幅 変更機構を用いて被固定部の幅寸法に対応させ、下部材先端部の圧接部を被固定 部の幅方向における両側縁下面に当接する。続いて、緊結手段を用いて下部材の 圧接部を被固定部両側縁の下面に圧接し、被固定部の両側縁を上下に強固に挟持 すればよい。下部材の後端に設けた回動支点を中心として下部材先端部の圧接部 が被固定部の下に圧接し、この力を上部材が受けて強固な固定が行なわれる。 That is, according to the above-described configuration, when fixing the beam member, first, the upper member constituting the fixing portion is placed on the fixed portion of the beam member, and the interval between the lower members facing each other is changed by the width changing mechanism. The pressure contact portion of the lower member tip portion is brought into contact with the lower surface of both side edges in the width direction of the fixed portion in correspondence with the width dimension of the fixed portion. Then, the pressure contact portion of the lower member may be pressed against the lower surface of both side edges of the fixed portion by using a binding means to firmly sandwich both side edges of the fixed portion in the vertical direction. The pressure contact portion of the tip end portion of the lower member is pressure-contacted below the fixed portion around the rotation fulcrum provided at the rear end of the lower member, and this force is received by the upper member to perform firm fixing.

【考案の効果】[Effect of device]

上述の結果、この考案によると、梁材に対する固定は、被固定部の幅方向にお ける両側縁を上下に挟むことによって行なわれるので、溶接なしで固定作業を行 なうことができる。 As a result of the above, according to the present invention, since the fixing to the beam is performed by sandwiching both side edges in the width direction of the fixed portion up and down, the fixing work can be performed without welding.

【００１０】 しかも、上部材と下部材との間には、相対向する下部材の間隔を、被固定部の 幅寸法に対応して変更する幅変更機構を介在しているので、Ｈ鋼の幅に関わりな く、どの大きさのＨ鋼に対しても強固な固定を行なうことができる。Moreover, since a width changing mechanism for changing the interval between the lower members facing each other according to the width dimension of the fixed portion is interposed between the upper member and the lower member, the H steel It can be firmly fixed to any size H steel regardless of the width.

【００１１】 また、上述の固定は、後端部に設けた回動支点を中心として回動する下部材の 圧接部と上部材とで、被固定部に噛付いたように挟持することで行なうので、被 固定部の厚みの異なるどのような大きさのＨ鋼に対してであっても強固に固定す ることができる。Further, the above-mentioned fixing is performed by sandwiching the pressure contact portion and the upper member of the lower member, which rotate around a rotation fulcrum provided at the rear end portion, as if they were engaged with the fixed portion. Therefore, it can be firmly fixed to H steels of any size with different thicknesses of the fixed portion.

【００１２】 さらに、固定作業は、例えばボルトナット等からなる緊結手段を締めるだけで よいので、溶接の場合に比して極めて簡易迅速に行なえる。Furthermore, since the fixing work only needs to be performed by tightening the tightening means such as a bolt and nut, it can be performed extremely simply and quickly as compared with the case of welding.

【００１３】 回動支点を、下部材の後端に支持突起を立設して形成したので、カシメ等によ り上部材と下部材とを相互に枢着するなどして接合する作業が不要となり、製造 が容易に行なえる。その上、下部材を上部材に対して自由に移動可能に構成でき るので、上部材と下部材との間に介在させる幅変更機構の構造を簡素にでき、製 造コストを低く押えることが可能となり、また高い強度を維持し、取付け作業を 円滑にすることができる。Since the rotation fulcrum is formed by vertically arranging the support protrusion at the rear end of the lower member, it is not necessary to join the upper member and the lower member by pivoting the upper member and the lower member to each other by caulking or the like. Therefore, it is easy to manufacture. Moreover, since the lower member can be configured to be freely movable with respect to the upper member, the structure of the width changing mechanism interposed between the upper member and the lower member can be simplified, and the manufacturing cost can be kept low. This makes it possible to maintain high strength and facilitate installation work.

These two joining members 5 and 5 are formed by pressing a metal plate, and connect the receiving plate 7 from the upper end of the vertical piece 6 to the outside, and from the lower end to the outside. The letter-shaped mounting plates 8 are connected to each other, and the reinforcing ribs 9 ...

【００１６】 また、垂直片６の上部には、これより上側部分を若干外側にずらす折曲線１０ を形成し、２つの接合部材５，５を接合したときに両者間に吊子１１（図１参照 ）を取付けるための隙間を形成できるようにしている。そしてその折曲線１０よ りも上側部分には、角孔１２を形成しており、吊子取付け用の根角ボルト１３が 挿入できるようにしている。 さらに、前述した取付け板８の水平面８ａにも同様に角孔１４を形成して、固 定部４に対する固定用の根角ボルト１５の挿入が行なえるようにしている。In addition, a fold curve 10 is formed on the upper portion of the vertical piece 6 so that the upper portion of the vertical piece 6 is shifted slightly outward, and when the two joining members 5 and 5 are joined together, the suspension 11 (FIG. It is possible to form a gap for attaching the reference). A square hole 12 is formed on the upper side of the folding curve 10 so that a root angle bolt 13 for attaching the suspension can be inserted. Further, a square hole 14 is similarly formed on the horizontal surface 8a of the above-mentioned mounting plate 8 so that a root angle bolt 15 for fixing to the fixing portion 4 can be inserted.

【００１７】 前述した固定部４は、上下に分離可能な上部材１６と、２つの下部材１７，１ ７とで構成している。 上部材１６は、短冊のように長い薄箱状に形成され、下面を開口している。そ して、上面には８つの挿通孔１８，１８，１９…を形成している。そのうちの２ つの挿通孔１８，１８は、長さ方向の中間部分に左右に並べて形成し、上述の根 角ボルト１５、およびワッシャ２０、スプリングワッシャ２１、ナット２２によ って接合部材５，５を固定できるようにし、他の挿通孔１９…は、長さ方向の両 端部から長さ方向に沿って所定間隔おきに３つずつ、上述の挿通孔１８，１８を 挟んで形成し、下部材１７、１７を取付けられるようにしている。The above-mentioned fixing portion 4 is composed of an upper member 16 which is vertically separable and two lower members 17 and 17. The upper member 16 is formed in a long thin box shape like a strip, and has an opening on the lower surface. Then, eight insertion holes 18, 18, 19 ... Are formed on the upper surface. Two of the insertion holes 18, 18 are formed side by side in the middle portion in the longitudinal direction, and the joint members 5, 5 are formed by the above-mentioned root bolt 15, the washer 20, the spring washer 21, and the nut 22. The other insertion holes 19 are formed by sandwiching the above-mentioned insertion holes 18, 18 from the both ends in the length direction at intervals of a predetermined distance along the length direction. The members 17 and 17 can be attached.

【００１８】 また、上述の挿通孔１９…のうち、中心側の４つの挿通孔には、これらよりも 所定間隔端部側位置に、下部材１７，１７の上部後端を端部側にずれないように 係止するための凹段部２３…をプレス加工により形成している。Further, among the above-mentioned insertion holes 19, the four insertion holes on the center side are displaced from the upper rear end of the lower members 17, 17 toward the end side by a predetermined interval end side position than these. The recessed step portions 23 are formed by press working so as to prevent them from being locked.

【００１９】 下部材１７は、上面と前面とを開口した薄箱状で、前後方向の長さを上述の挿 通孔１９…の間隔に対応させて形成するとともに、幅寸法を上部材１６のそれよ りも小さくして、上部材１６に対して下から嵌合可能なものとしている。The lower member 17 is in the form of a thin box having an open upper surface and a front surface, and is formed such that its length in the front-rear direction corresponds to the interval between the above-mentioned insertion holes 19 ... And the width dimension of the upper member 16. It is made smaller than that, and can be fitted to the upper member 16 from below.

【００２０】 そして後端には、補強壁２４を立設するとともに、両側壁２５，２５の後端部 に、上部材１６端部の内面と、上述の凹段部２３…とに下から当接する支持突起 ２６，２６を立設している。この支持突起２６，２６は、上端を尖鋭に形成する とともに、前方へかけて湾曲部２６ａと傾斜部２６ｂとを形成し、この下部材１ ７が上述の上部材１６に対して支持突起２５，２５の上端を支点として回動する ようにしている。At the rear end, a reinforcing wall 24 is provided upright, and at the rear end portions of the side walls 25, 25, the inner surface of the end portion of the upper member 16 and the above-mentioned concave step portion 23 are contacted from below. Supporting projections 26, 26 that are in contact with each other are provided upright. The upper ends of the support protrusions 26, 26 are sharpened, and a curved portion 26a and a sloped portion 26b are formed toward the front. The lower member 17 supports the upper member 16 above. The upper end of 25 is used as a fulcrum to rotate.

【００２１】 また、両側壁２５，２５の先端部は、その高さを若干低めに形成して、回動し たときにＨ鋼３の被固定部３ａに下から圧接する圧接部２７を形成している。Further, the front end portions of the both side walls 25, 25 are formed to have a slightly lower height, and a press-contact portion 27 is formed to press-contact the fixed portion 3a of the H steel 3 from below when rotating. is doing.

【００２２】 そして、上述の下部材１７の中央部には、前述した上部材１６の挿通孔１９１ …に対応する角孔２８を形成し、下から根角ボルト２９を挿通できるようにして いる。この角孔２８に挿通する根角ボルト２９は、緊結手段の一部を構成するも ので、上部材１６の挿通孔１９から突出した根角ボルト２９の先端部にワッシャ ３０とスプリングワッシャ３１とを挿嵌し、ナット３２で締付けることで上部材 １６と下部材１７とを緊結してＨ鋼３の被固定部３ａに対する挟持固定を行なう ようにしている。A square hole 28 corresponding to the above-described insertion hole 191 of the upper member 16 is formed in the central portion of the lower member 17 so that the root angle bolt 29 can be inserted from below. The root angle bolt 29 that is inserted into the square hole 28 constitutes a part of the tightening means. Therefore, the washer 30 and the spring washer 31 are inserted into the tip of the root angle bolt 29 that protrudes from the through hole 19 of the upper member 16. Then, by tightening with the nut 32, the upper member 16 and the lower member 17 are tightly connected, and the H steel 3 is clamped and fixed to the fixed portion 3a.

【００２３】 このように構成したタイトフレーム１の作用および効果を説明すると、使用は 、Ｈ鋼３所定位置の被固定部３ａに、図３に示したように固定して行なう。すな わち、被固定部３ａに対する固定は、まず、上部材１６の下側位置で相対向して いる下部材１７，１７同士の間隔を、下部材１７，１７の保持位置を三種類のう ちから適宜選定して被固定部３ａの幅に対応させる。例えば１２０ｍｍのような 幅広の被固定部３ａの場合には、下部材１７，１７の支持突起２６，２６を上部 材１６の端部に係止して、一番端部側の挿通孔１９，１９に根角ボルト２９を挿 通し、幅狭の被固定部３ａの場合には、下部材１７，１７の支持突起２６，２６ を一番中央側の凹暖部に係止して、根角ボルトを一番中央側の挿通孔１９，１９ に挿通する。The operation and effect of the thus constructed tight frame 1 will be described. The use is carried out by fixing it to the fixed portion 3a at a predetermined position of the H steel 3 as shown in FIG. That is, in fixing to the fixed portion 3a, first, the lower members 17 and 17 facing each other at the lower position of the upper member 16 are separated by three types of holding positions. It is appropriately selected from the above to correspond to the width of the fixed portion 3a. In the case of a wide fixed portion 3a having a width of 120 mm, for example, the supporting protrusions 26, 26 of the lower members 17, 17 are locked to the end portions of the upper member 16, and the insertion holes 19, Insert the root angle bolt 29 into 19 and, in the case of the fixed portion 3a having a narrow width, lock the support protrusions 26, 26 of the lower members 17, 17 to the concave warm portion on the most central side to fix the root angle bolt. Insert through the insertion holes 19 and 19 on the most central side.

【００２４】 そしてその後、上部材１６と下部材１７，１７とを緊結する緊結手段２９，３ ０，３１，３２を緩めて上部材１６をＨ鋼３の被固定部３ａに載置するとともに 、相互の間隔を被固定部３ａの幅に対応させた２つの下部材１７，１７を、Ｈ鋼 ３の被固定部３ａを上下方向から挟み、緊結手段２９，３０，３１，３２を締め ればよい。図３に示したように、下部材１７，１７の後端に形成した支持突起２ ６を支点として下部材１７，１７が回動し、先端部の圧接部２７，２７が被固定 部３ａの下側に圧接し、この力を上部材１６が受けて強固な固定が行なわれる。After that, the tightening means 29, 30, 31, 32 for tightly connecting the upper member 16 and the lower members 17, 17 are loosened to place the upper member 16 on the fixed portion 3a of the H steel 3, and By sandwiching the fixed portion 3a of the H steel 3 from above and below with the two lower members 17 and 17 whose mutual intervals correspond to the width of the fixed portion 3a, and tightening the binding means 29, 30, 31, 32. Good. As shown in FIG. 3, the lower members 17 and 17 rotate about the supporting projections 26 formed at the rear ends of the lower members 17 and 17, and the pressure contact portions 27 and 27 at the tip end of the fixed portion 3a. The upper member 16 is pressed against the lower side, and the upper member 16 receives this force to firmly fix the member.

【００２５】 したがって、Ｈ鋼３の被固定部３ａに対する固定は、被固定部３ａを上下に挟 むことによって行なわれるので、溶接なしで固定作業を行なうことができる。Therefore, since the H steel 3 is fixed to the fixed portion 3a by sandwiching the fixed portion 3a vertically, the fixing work can be performed without welding.

【００２６】 しかも、上部材１６に対する下部材１７，１７の保持は、相対向する２つの下 部材１７，１７の間隔を、被固定部３ａの幅寸法に対応して変更できるようにし ているので、Ｈ鋼３の幅に関わりなく、どの大きさのＨ鋼に対しても強固な固定 を行なうことができる。Moreover, since the lower members 17, 17 are held with respect to the upper member 16, the distance between the two lower members 17, 17 facing each other can be changed according to the width dimension of the fixed portion 3a. , H steel 3, regardless of the width, can be firmly fixed to H steel of any size.

【００２７】 また、上述の固定は、支持突起２６の上端を中心として回動する下部材１７， １７の圧接部２７と上部材１６とで、被固定部３ａに噛付いたように挟持するこ とで行なうので、どのような大きさのＨ鋼３であっても強固に固定することがで きる。Further, in the above-mentioned fixing, the pressing contact portion 27 of the lower members 17 and 17 rotating around the upper end of the support protrusion 26 and the upper member 16 are sandwiched so as to be engaged with the fixed portion 3a. Since it is performed by using the above method, it is possible to firmly fix the H steel 3 of any size.

【００２８】 さらに、固定作業は、ボルトナットからなる緊結手段２９，３０，３１，３２ を締めるだけでよいので、溶接の場合に比して極めて簡易迅速に行なえる。Further, since the fixing work only needs to be performed by tightening the tightening means 29, 30, 31, 32 composed of bolts and nuts, it can be performed extremely simply and quickly as compared with the case of welding.

【００２９】 さらに、上部材１６と下部材１７，１７とはそれぞれ別々に形成するだけでよ く、改めて接合する必要はないので、製造が容易に行なえる。Furthermore, since the upper member 16 and the lower members 17, 17 need only be formed separately and do not need to be joined again, manufacturing can be performed easily.

【００３０】 なお、他の実施例を説明すれば、図１に仮想線で示したように、上部材１６の 下端縁から水平方向に翼状の支持片３３…を延設するもよい。接合部材５，５下 端部の取付け板８の下端からも同様に、支持片を延設するもよい。この様にした 場合には、この支持片の下面が、Ｈ鋼３の上面に当接するので、タイトフレーム １を取付けた際の安定性を向上することができる。To describe another embodiment, as shown in phantom in FIG. 1, wing-shaped support pieces 33 ... May be extended horizontally from the lower end edge of the upper member 16. Similarly, a support piece may be extended from the lower end of the attachment plate 8 at the lower end of the joining members 5 and 5. In this case, the lower surface of this support piece contacts the upper surface of the H steel 3, so that the stability when the tight frame 1 is attached can be improved.

【００３１】 また、図４に示したタイトフレーム４１のように、二連式のものとするもよい 。このタイトフレーム４１では、各タイトフレーム４２，４２を構成する接合部 材４３，４３，４４，４４のうち対向するもの同士４４，４４の取付け板４５， ４５を、タイトフレーム４２，４２の所定の固定間隔に対応した間隔をあけて連 結している。また、他の接合部材４３，４３からは、上述の間隔の半分の長さの 延設部４６を形成している。このようにして取付け板４５，４５と延設部４６と を含む全長を取付けピッチに形成した場合、タイトフレーム４１の固定は、Ｈ鋼 の端から順番に並べて行くだけでよく、固定位置を測ったりする作業を省くこと ができ、作業性が向上する。Further, as in the tight frame 41 shown in FIG. 4, a double frame may be used. In this tight frame 41, the joint plates 43, 43, 44, 44 constituting the respective tight frames 42, 42, which are opposed to each other, are attached to the mounting plates 45, 45 by a predetermined amount. They are connected at intervals that correspond to the fixed intervals. Further, from the other joining members 43, 43, an extending portion 46 having a length half the above-mentioned interval is formed. When the entire length including the mounting plates 45, 45 and the extended portion 46 is formed at the mounting pitch in this way, the tight frames 41 can be fixed only by sequentially arranging from the end of the H steel, and the fixing position can be measured. The work to be done can be omitted and the workability is improved.

【００３２】 さらに、図５に示したように、上部材１６に対する下部材１７の保持の仕方を 、プレス加工により形成した切込みのない凸部５１の内上面に係止して行なうよ うにするもよい。先の実施例の場合と同一の構成部分には同一の符号を付してお く。Further, as shown in FIG. 5, the method of holding the lower member 17 with respect to the upper member 16 may be carried out by engaging with the inner upper surface of the notched convex portion 51 formed by press working. Good. The same components as those in the previous embodiment are designated by the same reference numerals.

【００３４】 このように構成した固定部６３では、まず一端部をＨ鋼３の一端に係止すると ともに、他端側の下部材６２をＨ鋼３の幅に合わせて、長さ方向に適宜移動する 。そして、各緊結手段（根角ボルト６５，とワッシャ６６、スプリングワッシャ ６７、ナット６８）を用いて上部材６３と下部材６２，６２との緊結を行ない、 Ｈ鋼３に対する固定を行なう。 また、固定部を構成する下部材の圧接部は、下 部材先端部の両側壁に、断面コ字状の圧接板を傾動可能に枢支して構成するもよ い。このようにした場合には、タイトフレームの固定時に、圧接板の上面が被固 定部の傾きに対応して面で強く密着するので、強固な固定状態を得ることができ る。なお、圧接板の上面に凹凸を形成して高い滑り止め効果を期待するもよい。In the fixing portion 63 configured as described above, first, one end is locked to one end of the H steel 3, and the lower member 62 on the other end side is adjusted to the width of the H steel 3 as appropriate in the length direction. Moving . Then, the upper member 63 and the lower members 62, 62 are tightly connected to each other by using the respective tightening means (root angle bolts 65, washers 66, spring washers 67, nuts 68) and fixed to the H steel 3. In addition, the pressure contact portion of the lower member that constitutes the fixed portion may be configured by tiltably supporting a pressure contact plate having a U-shaped cross section on both side walls of the tip end portion of the lower member. In such a case, when the tight frame is fixed, the upper surface of the pressure contact plate closely adheres to the surface in correspondence with the inclination of the fixed portion, so that a strong fixed state can be obtained. In addition, you may expect high anti-slip effect by forming unevenness | corrugation on the upper surface of a press contact plate.

【００３５】 そしてまた、屋根材は先の実施例のように吊子１１を介して固定するようにせ ずともよく、したがって、本体２の形状も他の様々なものを採用できる。Further, the roofing material does not have to be fixed via the suspension 11 as in the previous embodiment, and therefore, the main body 2 can have various other shapes.

【００３６】 なお、この考案の幅変更機構は、前述した一実施例の構成における上部材１６ 端部と２つの凹段部２３，２３と、上部材１６と下部材１７，１７とを緊結する 緊結手段２９，３０，３１，３２とに対応する。The width changing mechanism of the present invention tightly connects the end portion of the upper member 16 and the two concave step portions 23, 23, and the upper member 16 and the lower members 17, 17 in the configuration of the above-described embodiment. It corresponds to the binding means 29, 30, 31, 32.
