In particular, the present invention relates to a vertical stacking method of extrusion-molded cement boards and its structure.

従来、複数の押出成形セメント板（パネル壁材）１，２を縦張り方式で上下多段にビル等の梁に建て込むときは、図５０に示すように、先ず、床スラブ３下面に設けたＨ形鋼製梁４の上側水平フランジ部に、断面Ｌ字形のピースアングル（連結金具）５を介して、上段壁材載置支持用の断面Ｌ字形通しアングル６を水平方向に連結固定し、次に、前記梁４の下側水平フランジ部に、下段壁材固定支持用の通しアングル７を水平方向に連結固定する。 Conventionally, when a plurality of extrusion-molded cement boards (panel wall materials) 1 and 2 are installed on a beam such as a building in a vertically extending manner in a vertically extending manner, first, as shown in FIG. 50, first provided on the lower surface of the floor slab 3 An L-shaped through-angle 6 for supporting the upper wall material is horizontally connected and fixed to the upper horizontal flange portion of the H-shaped steel beam 4 via an L-shaped piece angle (connecting bracket) 5. Next, a through angle 7 for fixing and supporting the lower wall material is connected and fixed to the lower horizontal flange portion of the beam 4 in the horizontal direction.

この後、上段の通しアングル６の水平フランジ部にセメント板１を載置し、上段通しアングル６の鉛直フランジ部に断面Ｚ形のＺクリップ（連結金具）８を挟むと共に、該Ｚクリップ８とセメント板１をボルト９で締め付けることにより、上段の通しアングル６に上段のセメント板１を締結固定する。 Thereafter, the cement plate 1 is placed on the horizontal flange portion of the upper through angle 6, and a Z clip (connecting metal fitting) 8 having a Z-shaped cross section is sandwiched between the vertical flange portions of the upper through angle 6. By tightening the cement plate 1 with bolts 9, the upper cement plate 1 is fastened and fixed to the upper through angle 6.

又、下段通しアングル７の鉛直フランジ部に前記Ｚクリップ８の上部を溶接すると共に、該Ｚクリップ８と下段のセメント板２をボルト９で締め付けることにより、下段通しアングル７に該セメント板２を締結固定する（特許文献１参照）。尚、符号１０はモルタル、１１は層間閉塞用ロックウール、１２は無機質断熱材、１３はシーリング材である。

特許文献１記載の上記セメント板の縦積み工法によれば、梁４の上部、下部に上段通しアングル６、下段通しアングル７を取り付け、下段通しアングル７の鉛直フランジ部に下段セメント板２を連結固定すると共に上段通しアングル６の水平フランジ部に上段セメント板１を載置して連結固定する。 According to the vertical stacking method of the cement plate described in Patent Document 1, the upper passage angle 6 and the lower passage angle 7 are attached to the upper and lower portions of the beam 4, and the lower cement plate 2 is connected to the vertical flange portion of the lower passage angle 7. At the same time, the upper cement board 1 is placed on the horizontal flange portion of the upper through angle 6 and fixedly connected.

従って、上下２段のセメント板１，２を建て込むには、上下２本の通しアングル６，７を必要とし、且つ、２本の通しアングル６，７に夫々専用の連結金具を使用しなければならない。このため、前記セメント板１，２の上下２段当たりの通しアングル６，７及び連結金具の数が多くなり、工期が長期化すると共に材料費が嵩むという問題があった。 Therefore, in order to install the upper and lower two-stage cement plates 1 and 2, the upper and lower two through angles 6 and 7 are required, and a dedicated connecting bracket must be used for each of the two through angles 6 and 7. I must. For this reason, there are problems that the through-angles 6 and 7 and the number of connecting fittings per upper and lower two stages of the cement plates 1 and 2 are increased, the construction period is prolonged and the material cost is increased.

特に、下段セメント板２の上端部が固定されていないため、長期に渡る乾湿繰返しによる、セメント板表裏面の寸法変化差等により、反りや撓みによる仕上がり面の目違いが生じて施工品質が低下する。又、上記梁４に取り付けたピースアングル５に、セメント板１を支持するための通しアングル６を溶接し、該上段通しアングル６の短い溶接部に上段セメント板１の重量が集中的に作用するので、該セメント板１に対する支持強度が低下する。更に、例えば、複数の縦張りセメント板１，２間に地震力が作用した場合、両者間に地震力による大きな変位が発生し易いため、防水上の観点からも構造的に不利になる。 In particular, since the upper end of the lower cement board 2 is not fixed, due to repeated changes in the wet and wet conditions over a long period of time, differences in the dimensions of the front and back surfaces of the cement board may cause a difference in the finished surface due to warping or bending, resulting in poor construction quality. To do. Further, a through angle 6 for supporting the cement plate 1 is welded to the piece angle 5 attached to the beam 4, and the weight of the upper cement plate 1 acts intensively on the short welded portion of the upper through angle 6. Therefore, the support strength with respect to the cement board 1 is lowered. Furthermore, for example, when a seismic force is applied between the plurality of vertical cement plates 1 and 2, a large displacement due to the seismic force is likely to occur between them, which is structurally disadvantageous from the viewpoint of waterproofing.

そこで、セメント板の上下２段当たりの通しアングル及び連結金具等の部品点数を少なくし、工期の短縮、材料費の削減及び施工品質の向上を図るために解決すべき技術的課題が生じてくるのであり、本発明は該課題を解決することを目的とする。 Therefore, there are technical issues that need to be solved to reduce the number of parts such as through-angles and connecting brackets for the upper and lower stages of the cement board, shorten the construction period, reduce material costs, and improve construction quality. Therefore, an object of the present invention is to solve the problem.

The clips 33 are arranged at appropriate intervals on both sides of the cement plate weight receiving member 27. Further, the Z clip 33 has a stepped portion 33a at an intermediate portion in the vertical direction, and a vertically long elongated bolt hole 33b is formed in the vertical flange portion above the stepped portion 33a. Further, the Z clip 33 is fastened and fixed to the upper cement plate 19 by a bolt 34 penetrating the long hole 33b, and the vertical flange portion 24a of the through angle 24 is fitted to the vertical flange portion 33c below the step portion 33a. The inner surface is fixed by tightening.

各Ｚクリップ３３と対応する通しアングル２４の外面側には縦長の連結プレート（上段用平形連結金具。短冊プレ−トともいう。）３５が設けられ、該連結プレート３５の下部には、図８に示すように、縦長のボルト用長孔３５ａが形成されている。又、前記連結プレート３５は、長孔３５ａを貫通するボルト３６により、下段セメント板１５の上部に締結固定されている。更に、該連結プレート３５の上側端部は、下段セメント板１５よりも上側に突出し、該突出部分は前記通しアングル２４の鉛直フランジ部２４ａに溶接にて固定されている。尚、符号３７はナット、３８は層間閉塞用ロックウールである。 On the outer surface side of the through-angle 24 corresponding to each Z clip 33, a vertically long connecting plate (a flat connecting metal fitting for the upper stage, also referred to as a strip plate) 35 is provided. As shown in FIG. 3, a vertically long elongated bolt hole 35a is formed. The connecting plate 35 is fastened and fixed to the upper portion of the lower cement plate 15 by bolts 36 penetrating the long holes 35a. Further, the upper end portion of the connecting plate 35 protrudes above the lower cement plate 15, and the protruding portion is fixed to the vertical flange portion 24 a of the through angle 24 by welding. Reference numeral 37 denotes a nut, and 38 denotes an interlayer blocking rock wool.

次に、上記断面Ｌ字形の通しアングル２４を１本のみ用いて、建造物の梁２６に上下２段の縦張り用セメント板（中空パネル壁材）１５，１９を建込む際の手順について説明する。先ず、前記梁２６の水平上面に通しアングル２４の水平フランジ部２４ｂを溶接し、該通しアングル２４の長手方向中央部の鉛直フランジ部２４ａにセメント板自重受け部材２７を嵌合して溶接する。この場合、セメント板自重受け部材２７の嵌合用隙間Ｓを通しアングル２４の鉛直フランジ部２４ａに上方より係止嵌合し、嵌合後に通しアングル２４にセメント板自重受け部材２７の周縁部を溶接固定する。 Next, a description will be given of a procedure for installing vertical cement boards (hollow panel wall materials) 15 and 19 in two upper and lower stages on a beam 26 of a building using only one through-angle 24 having an L-shaped cross section. To do. First, the horizontal flange portion 24b of the through angle 24 is welded to the horizontal upper surface of the beam 26, and the cement plate self-weight receiving member 27 is fitted and welded to the vertical flange portion 24a of the longitudinal center portion of the through angle 24. In this case, the cement plate self-weight receiving member 27 is fitted through the fitting gap S through the vertical flange 24a of the angle 24 from above, and the peripheral edge of the cement plate self-weight receiving member 27 is welded to the through angle 24 after the fitting. Fix it.

又、下段セメント板１５には連結プレート３５の下部をボルト３６により固定する。固定後、連結プレート３５の上部を前記通しアングル２４の鉛直フランジ部２４ａの内面側に溶接固定する。従って、前記通しアングル２４に下段セメント板１５が強固に支持固定される。斯くして、前記梁２６に固設した１本の通しアングル２４に、上下２段のセメント板１５，１９が強固に建て込まれる。 Further, the lower part of the connecting plate 35 is fixed to the lower cement plate 15 with bolts 36. After fixing, the upper part of the connecting plate 35 is welded and fixed to the inner surface side of the vertical flange portion 24 a of the through angle 24. Accordingly, the lower cement plate 15 is firmly supported and fixed to the through angle 24. Thus, the upper and lower two-stage cement plates 15 and 19 are firmly built in one through angle 24 fixed to the beam 26.

次に、前記セメント板自重受け部材２７の水平フランジ部２８ｂに上段セメント板１９を載置すると共に、該上段セメント板１９にＺクリップ３３の上部をボルト３４により固定する。すると、該Ｚクリップ３３の下部により前記通しアングル２４の鉛直フランジ部２４ａの外面部が挟んで締め付け固定される。 Next, the upper cement plate 19 is placed on the horizontal flange portion 28 b of the cement plate self-weight receiving member 27, and the upper portion of the Z clip 33 is fixed to the upper cement plate 19 with bolts 34. Then, the outer surface portion of the vertical flange portion 24a of the through angle 24 is clamped and fixed by the lower portion of the Z clip 33.

斯くして、前記通しアングル２４に上段セメント板１９が強固に支持固定される。即ち、通しアングル２４内面側に前記Ｚクリップ３３の下側鉛直フランジ部３３ｃを挟み付けて固定することにより、該通しアングル２４に上段セメント板１９が一体的に連結される。 Thus, the upper cement plate 19 is firmly supported and fixed to the through angle 24. That is, the upper vertical cement board 19 is integrally connected to the through angle 24 by sandwiching and fixing the lower vertical flange portion 33 c of the Z clip 33 to the inner surface side of the through angle 24.

従来技術では、上下２段のセメント板１５，１９を建て込む際に、２本の通しアングル５，６及びピースアングル７を使用する必要があったが、本発明では、通しアングル２４の数が１本で済み、且つ、ピースアングル（連結金具）が不要になる。従って、通しアングル及び連結金具等を大幅に削減できるので、その分だけ部品点数が削減されると共に、該部品の組付け工数も少なくなり、大幅な工期短縮が達成される。 In the prior art, it is necessary to use the two through angles 5 and 6 and the piece angle 7 when installing the upper and lower cement plates 15 and 19, but in the present invention, the number of through angles 24 is reduced. Only one piece is required, and a piece angle (connecting bracket) is not required. Therefore, the through angle and the connecting metal fittings can be greatly reduced, so that the number of parts is reduced by that amount, and the number of assembling steps of the parts is reduced, and the construction period is greatly shortened.

本発明は、従来例とは異なり、下段セメント板１５上端部の跳ね出しがなくなり、反りや撓みによる仕上がり面の目違いが生じ難くなる。更に、従来は、梁に取り付けたピースアングルに上段セメント板１９の重量が作用し、且つ、通しアングル２４の短い溶接部分のみで上段セメント板１９を支持する構造であるので、支持強度の面で不利になっていた。 In the present invention, unlike the conventional example, the upper end portion of the lower cement plate 15 does not jump out, and it is difficult to cause a difference in the finished surface due to warping or bending. Furthermore, the conventional structure is such that the weight of the upper cement plate 19 acts on the piece angle attached to the beam, and the upper cement plate 19 is supported only by the short welded portion of the through angle 24. It was a disadvantage.

この点、本発明では、上段セメント板１９の重量を十分支持するべく、上記セメント板自重受け部材２７の溶接長を所要寸法に設定でき、且つ、セメント板自重受け部材２７が通しアングル２４の上端部に掛止連結される二股形状部を有するので、上段セメント板１９に対する支持強度が著しく増大する。 In this regard, in the present invention, the weld length of the cement plate self-weight receiving member 27 can be set to a required dimension so as to sufficiently support the weight of the upper cement plate 19, and the cement plate self-weight receiving member 27 passes through the upper end of the angle 24. Since the forked portion is hooked and connected to the portion, the support strength for the upper cement plate 19 is remarkably increased.

更に、本発明は、縦張りのセメント板１５，１９間の取り合い部において、接点が横一本であるため、従来の持ち出し構造に比べて、縦張りのセメント板の相互間の変位が少なくなり、防水面でかなり有利になる。 Further, according to the present invention, since the contact point is one side at the joint portion between the vertical cement plates 15 and 19, the displacement between the vertical cement plates is reduced as compared with the conventional take-out structure. It will be quite advantageous in terms of waterproofing.

更に又、縦張りのセメント板１５等の取付け部は、４点止め方式の構造を有するので、セメント板１５等の加重負担が増大する恐れはない。又、下段セメント板１５上部に取り付けた連結プレート３５は、その上側鉛直フランジ部が上段セメント板１９の下部を鉛直状態で支持固定するので、上段セメント板１９の幅方向中央部がセメント板自重受け部材２７により鉛直状態で支持固定されることと相俟って、該セメント板１９のバタツキを良好に防止することができる。 Furthermore, since the attachment portion of the vertical cement board 15 or the like has a four-point structure, there is no fear that the load on the cement board 15 or the like will increase. Further, the upper vertical flange portion of the connecting plate 35 attached to the upper portion of the lower cement plate 15 supports and fixes the lower portion of the upper cement plate 19 in a vertical state, so that the central portion of the upper cement plate 19 in the width direction receives the weight of the cement plate itself. Coupled with being supported and fixed in a vertical state by the member 27, the cement plate 19 can be prevented from fluttering well.

尚、セメント板自重受け部材２７のセメント板１５に掛止される二股形状部の幅は所要寸法（約８０ｍｍ）に設定できるので、両者のロッキングを一層容易に実施できるメリットを有する。 In addition, since the width of the bifurcated portion hooked to the cement plate 15 of the cement plate self-weight receiving member 27 can be set to a required dimension (about 80 mm), there is an advantage that both can be locked more easily.

次に、本発明の実施例２について図９乃至図２１に基づいて説明する。本実施例の特徴１つは、連結プレート４０の下部を下段セメント板１５に締付け固定し、且つ、連結プレート４０の上部をＺクリップ４１に重合させて締付け固定したことにある。なお、セメント板自重受け部材２７の構成は実施例１と同様である（図６参照）。 Next, a second embodiment of the present invention will be described with reference to FIGS. One feature of the present embodiment is that the lower part of the connecting plate 40 is fastened and fixed to the lower cement plate 15 and the upper part of the connecting plate 40 is overlapped with the Z clip 41 and fastened and fixed. In addition, the structure of the cement board own weight receiving member 27 is the same as that of Example 1 (refer FIG. 6).

図９に示すように、連結プレート４０の下部中央箇所には、ボルト４２が貫通する縦長の長孔４３が形成されていると共に、連結プレート４０の上縁部中央箇所には、縦長のボルト４４貫通用長孔４５が切り欠けられている。 As shown in FIG. 9, a vertically long slot 43 through which the bolt 42 penetrates is formed at the lower center portion of the connecting plate 40, and a vertically long bolt 44 is formed at the center portion of the upper edge portion of the connecting plate 40. The through hole 45 is cut out.

前記Ｚクリップ４１は、上下方向中央部の左右両側に傾斜して形成された段差部４６と、該段差部４６の下側に連設された枠形の下側鉛直フランジ部４７と、段差部４６の上側に連設された上側鉛直フランジ部４８とから成り、上側鉛直フランジ部４８の上縁部には、縦長のボルト４４貫通用長孔４９が切り欠けられている。 The Z clip 41 includes a stepped portion 46 formed to be inclined on both the left and right sides of the central portion in the vertical direction, a frame-shaped lower vertical flange portion 47 continuously provided on the lower side of the stepped portion 46, and a stepped portion. The upper vertical flange portion 48 is formed on the upper edge of the upper vertical flange portion 48, and a long hole 49 for penetrating the vertically long bolt 44 is notched.

更に、上側鉛直フランジ部４８の下端部には挟持板５１が垂下して延設され、該挟持板５１と下側鉛直フランジ部４７との間には、通しアングル２４の鉛直フランジ部２４ａを挟持嵌合するためのアングル用隙間Ｔ１が形成されている。また、枠形下側鉛直フランジ部４７の下縁両側部は縦断Ｌ字形状に形成されている。さらに、該Ｌ字形状部５０と対応する下側鉛直フランジ部４７内には、連結プレート４０の上部を上方へ挿通させるために、挟持板５１と下辺部５２の間にプレート用隙間Ｔ２が形成されている。 Further, a clamping plate 51 extends downward from the lower end portion of the upper vertical flange portion 48, and the vertical flange portion 24 a of the through angle 24 is sandwiched between the clamping plate 51 and the lower vertical flange portion 47. An angle gap T1 for fitting is formed. Further, both side portions of the lower edge of the frame-shaped lower vertical flange portion 47 are formed in a longitudinal L shape. Further, in the lower vertical flange portion 47 corresponding to the L-shaped portion 50, a plate gap T2 is formed between the holding plate 51 and the lower side portion 52 so as to insert the upper portion of the connecting plate 40 upward. Has been.

実際に壁材を建込む際の手順の一例について説明すると、図１０及び図１１に示すように、先ず、梁２６の上面に通しアングル２４の水平フランジ部２４ｂを溶接すると共に、下段セメント板１５の左右方向（ＬＲ）両側部の上部にそれぞれ連結プレート４０をボルト４２により締付け固定し、この後、連結プレート４０の上下方向中間部を通しアングル２４の鉛直フランジ部２４ａに接する様に建て込む。 An example of the procedure for actually building the wall material will be described. As shown in FIGS. 10 and 11, first, the horizontal flange portion 24b of the angle 24 is welded to the upper surface of the beam 26, and the lower cement plate 15 is welded. The connecting plate 40 is fastened and fixed to the upper portions of both sides of the left and right direction (LR) by bolts 42, and thereafter, the connecting plate 40 is built so as to be in contact with the vertical flange portion 24a of the angle 24 through the vertical middle portion.

次に、連結プレート４０の真上にＺクリップ４１を配置し、該Ｚクリップ４１を連結プレート４０側に下降させる（図１２及び図１３）。これにより、下側鉛直フランジ部４７のプレート用隙間Ｔ２を連結プレート４０が上側へ挿通して嵌合すると、下側鉛直フランジ部４７と挟持板５１間のアングル用隙間Ｔ１に通しアングル２４の鉛直フランジ部２４ａが仮止めされる（図１４及び図１５）。この状態では、連結プレート４０がＺクリップ４１の下側鉛直フランジ部５２により水平方向への移動が拘束され、下段セメント板１５が仮止めされ、且つ、双方の長孔４５及び長孔４９が互いに一致するように位置して、連結プレート４０がＺクリップ４１の外面側に相互重合する。 Next, the Z clip 41 is disposed right above the connecting plate 40, and the Z clip 41 is lowered to the connecting plate 40 side (FIGS. 12 and 13). As a result, when the connecting plate 40 is inserted and fitted to the plate gap T2 of the lower vertical flange portion 47 upward, the angle 24 is vertically passed through the angle gap T1 between the lower vertical flange portion 47 and the holding plate 51. The flange portion 24a is temporarily fixed (FIGS. 14 and 15). In this state, the movement of the connecting plate 40 in the horizontal direction is restricted by the lower vertical flange portion 52 of the Z clip 41, the lower cement plate 15 is temporarily fixed, and both the long holes 45 and 49 are mutually connected. Positioned so as to coincide with each other, the connecting plate 40 is superposed on the outer surface side of the Z clip 41.

而して、図１６及び図１７に示すように、通しアングル２４の長手方向中央部の真上にセメント板自重受け部材２７を配置し、セメント板自重受け部材２７を通しアングル２４側へ下降させる。これにより、通しアングル２４の鉛直フランジ部２４ａがセメント板自重受け部材２７の隙間Ｓに嵌合して係止固定される（図１８及び図１９）。この後、セメント板自重受け部材２７の周縁部を鉛直フランジ部２４ａに溶接にて固着する。 Thus, as shown in FIGS. 16 and 17, the cement plate self-weight receiving member 27 is disposed right above the central portion in the longitudinal direction of the through-angle 24, and the cement plate self-weight receiving member 27 is lowered to the through-angle 24 side. . Accordingly, the vertical flange portion 24a of the through angle 24 is fitted and locked in the gap S of the cement plate self-weight receiving member 27 (FIGS. 18 and 19). Thereafter, the peripheral edge portion of the cement plate self-weight receiving member 27 is fixed to the vertical flange portion 24a by welding.

固着後、セメント板自重受け部材２７の水平フランジ部２８ｂ上に上段セメント板１９を載置し、上段セメント板１９の下部に連結プレート４０及びＺクリップ４１をボルト４４にて締付け固定する（図２０及び図２１）。すると、該Ｚクリップ４１の下部が前記通しアングル２４の鉛直フランジ部２４ａの外面部を挟んで締め付け固定する。斯くして、１本の通しアングル２４に、上下２段のセメント板１５，１９が強固に建て込まれ、実施例１と同様の効果を奏する。 After fixing, the upper cement plate 19 is placed on the horizontal flange portion 28b of the cement plate weight receiving member 27, and the connecting plate 40 and the Z clip 41 are fastened and fixed to the lower portion of the upper cement plate 19 with bolts 44 (FIG. 20). And FIG. 21). Then, the lower portion of the Z clip 41 is clamped and fixed by sandwiching the outer surface portion of the vertical flange portion 24a of the through angle 24. Thus, the upper and lower two-stage cement plates 15 and 19 are firmly built in one through angle 24, and the same effects as those of the first embodiment are obtained.

次に、本発明の実施例３について図２２乃至図３５に基づいて説明する。本実施例の特徴は、下段用連結金具を、通しアングル２４の鉛直フランジ部２４ａに係合する逆Ｊ形係止部材５５と、該係止部材５５の下部を保持するための上面開口形保持部５６を有する取付け部材５７とから構成したことにある。逆Ｊ形係止部材５５は、その下部を取付け部材５７の保持部５６に挿通保持させた状態で、保持部５６及び通しアングル２４に嵌合仮止めして固着される。 Next, Embodiment 3 of the present invention will be described with reference to FIGS. The feature of the present embodiment is that the lower connecting metal fitting is engaged with the vertical flange portion 24a of the through angle 24, and the upper surface opening type holding for holding the lower portion of the locking member 55. The mounting member 57 has a portion 56. The inverted J-shaped locking member 55 is fixedly fitted and temporarily fixed to the holding portion 56 and the through-angle 24 in a state where the lower portion is inserted and held in the holding portion 56 of the mounting member 57.

実際に壁材を建込む際は、図２２及び図２３に示すように、先ず、梁２６に通しアングル２４の水平フランジ部２４ｂを溶接すると共に、下段セメント板１５の左右方向両側部の上部にそれぞれ、取付け部材５７の下部をボルト４２により締付け固定する。この後、図２４及び図２５に示すように、取付け部材５７の真上に逆Ｊ形係止部材５５を配置し、該係止部材５５を取付け部材５７側に下降させる。これにより、逆Ｊ形係止部材５５の上側係合部５９内側に通しアングル２４の鉛直フランジ部２４ａが嵌合係止されると共に、係止部材５５の下部が取付け部材５７の保持部５６に挿通保持される（図２６及び図２７）。この状態で、係止部材５５を下部保持部５６及び通しアングル２４に嵌合仮止めして固着する。 When actually building the wall material, as shown in FIGS. 22 and 23, first, the horizontal flange portion 24b of the angle 24 is welded through the beam 26, and at the upper part of the left and right side portions of the lower cement plate 15 The lower portions of the attachment members 57 are fastened and fixed by bolts 42, respectively. Thereafter, as shown in FIGS. 24 and 25, the inverted J-shaped locking member 55 is disposed immediately above the mounting member 57, and the locking member 55 is lowered toward the mounting member 57. Accordingly, the vertical flange 24 a of the angle 24 is fitted and locked inside the upper engagement portion 59 of the inverted J-shaped locking member 55, and the lower portion of the locking member 55 is fixed to the holding portion 56 of the mounting member 57. It is inserted and held (FIGS. 26 and 27). In this state, the locking member 55 is temporarily fixed by fitting to the lower holding portion 56 and the through angle 24.

而して、図２８及び図２９に示すように、通しアングル２４の長手方向中央部の真上にセメント板自重受け部材２７を配置して、セメント板自重受け部材２７を通しアングル２４側に下降させる。これにより、通しアングル２４の鉛直フランジ部２４ａがセメント板自重受け部材２７の隙間Ｓに嵌合して固定される（図３０及び図３１）。このあと、セメント板自重受け部材２７の周縁部を通しアングル２４に溶接にて固着する
固着後、セメント板自重受け部材２７の水平フランジ部２８ｂ上に上段セメント板１９を載置させる。そして、係止部材５５及び取付け部材５７に対して、セメント板自重受け部材２７側（通しアングル２４の長手方向中央側）の箇所にＺクリップ４１を配置し、Ｚクリップ４１を上段セメント板１９の下部にボルト４４にて締付け固定する（図３２及び図３３）。すると、該Ｚクリップ４１の下部が前記通しアングル２４の鉛直フランジ部２４ａの外面部を挟んで締め付け固定する。斯くして、１本の通しアングル２４に、上下２段のセメント板１５，１９が強固に建て込まれ、実施例１と同様の効果を奏する。 Thus, as shown in FIGS. 28 and 29, the cement plate self-weight receiving member 27 is arranged right above the longitudinal center of the through-angle 24, and the cement plate self-weight receiving member 27 is lowered to the through-angle 24 side. Let Accordingly, the vertical flange portion 24a of the through angle 24 is fitted and fixed in the gap S of the cement plate self-weight receiving member 27 (FIGS. 30 and 31). Then, the upper stage cement board 19 is mounted on the horizontal flange part 28b of the cement board own weight receiving member 27 after fixing by fixing to the angle 24 through the peripheral part of the cement board own weight receiving member 27 by welding. Then, with respect to the locking member 55 and the attachment member 57, the Z clip 41 is disposed at a location on the cement plate own weight receiving member 27 side (longitudinal direction center side of the through angle 24), and the Z clip 41 is attached to the upper cement plate 19. The lower part is fastened and fixed with bolts 44 (FIGS. 32 and 33). Then, the lower portion of the Z clip 41 is clamped and fixed by sandwiching the outer surface portion of the vertical flange portion 24a of the through angle 24. Thus, the upper and lower two-stage cement plates 15 and 19 are firmly built in one through angle 24, and the same effects as those of the first embodiment are obtained.

尚、図示例では、係止部材５５及び取付け部材５７に対して、セメント板自重受け部材２７側の箇所にＺクリップ４１を取り付けているが、Ｚクリップ４１の取付け位置は特に限定されるべきではなく、図３４及び図３５に示すように、係止部材５５及び取付け部材５７に対して、セメント板自重受け部材２７と反対側（通しアングル２４の長手方向外端側）の箇所にＺクリップ４１を取り付けてもよい。 In the illustrated example, the Z clip 41 is attached to a location on the cement plate self-weight receiving member 27 side with respect to the locking member 55 and the attachment member 57, but the attachment position of the Z clip 41 should not be particularly limited. However, as shown in FIGS. 34 and 35, the Z clip 41 is provided at a position opposite to the cement plate self-weight receiving member 27 (the outer end side in the longitudinal direction of the through angle 24) with respect to the locking member 55 and the mounting member 57. May be attached.

次に、本発明の実施例４について図３６乃至図４６に基づいて説明する。本実施例の特徴は、図３６に示すように、連結金具６０の下部側外面の中間部に、縦断面Ｌ形の下段セメント板用保持部６１を連設すると共に、連結金具６０の上部側内面の両側縁部にそれぞれ、側面視Ｌ形のアングル用保持部６２を連設したことにある。更に、連結金具６０の上部を平面視コ字形に形成し、該コ字形部６３の内側に、ボルト挿通用長孔６４を有するＺクリップ４１の下部が上方から嵌合係止するように構成されている。なお、下段セメント板用保持部６１及びアングル用保持部６２の形状はそれぞれ、下段セメント板１５及び通しアングル２４に嵌合する形状であれば、任意の形状を採用しうる。 Next, a fourth embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 36, the present embodiment is characterized in that a lower cement board holding portion 61 having an L-shaped longitudinal section is connected to an intermediate portion of the outer surface on the lower side of the connection fitting 60 and the upper side of the connection fitting 60. The reason is that angle holding portions 62 having an L shape in a side view are connected to both side edge portions of the inner surface. Furthermore, the upper part of the connecting metal fitting 60 is formed in a U shape in plan view, and the lower part of the Z clip 41 having the bolt insertion long hole 64 is fitted and locked from above inside the U-shaped part 63. ing. In addition, as long as the shape of the holding part 61 for lower cement boards and the holding part 62 for angles is a shape fitted to the lower cement board 15 and the through angle 24, respectively, arbitrary shapes can be employ | adopted.

連結金具６０を側方から見ると、連結金具６０の下部外面と保持部６１との間に空間部が形成され、該空間部には下段セメント板１５の上縁部が嵌合係止される。また、連結金具６０の上部内面と保持部６２との間にも空間部が形成され、該空間部には通しアングル２４の鉛直フランジ部２４ａが嵌合係止される。 When the connection fitting 60 is viewed from the side, a space is formed between the lower outer surface of the connection fitting 60 and the holding portion 61, and the upper edge of the lower cement plate 15 is fitted and locked in the space. . Further, a space portion is also formed between the upper inner surface of the connection fitting 60 and the holding portion 62, and the vertical flange portion 24a of the through angle 24 is fitted and locked in the space portion.

実際に壁材を建込む際は、図３７及び図３８に示すように、梁２６に通しアングル２４の水平フランジ部２４ｂを溶接する。そして、下段セメント板１５の左右方向両側部の真上に連結金具６０を配置し、連結金具６０を下段セメント板１５側に下降させる。これにより、連結金具６０の下側保持部６１が下段セメント板１５の内側上縁部に嵌合係止されると共に、連結金具６０の上部内面と保持部６２間の空間部に、通しアングル２４の鉛直フランジ部２４ａが嵌合係止される（図３９及び図４０）。 When the wall material is actually built, the horizontal flange portion 24b of the angle 24 is welded through the beam 26 as shown in FIGS. And the connection metal fitting 60 is arrange | positioned right above the left-right direction both sides of the lower cement board 15, and the connection metal fitting 60 is lowered | hung to the lower cement board 15 side. As a result, the lower holding portion 61 of the connection fitting 60 is fitted and locked to the inner upper edge portion of the lower cement plate 15, and the through angle 24 is formed in the space between the upper inner surface of the connection fitting 60 and the holding portion 62. The vertical flange portion 24a is fitted and locked (FIGS. 39 and 40).

そして、図４１及び図４２に示すように、通しアングル２４の長手方向中央部の真上にセメント板自重受け部材２７を配置して、これを下降させる。このことにより、通しアングル２４の鉛直フランジ部２４ａにセメント板自重受け部材２７が嵌合固定される。この後、セメント板自重受け部材２７の周縁部を通しアングル２４に溶接にて固着する（図４３及び図４４）。 Then, as shown in FIGS. 41 and 42, the cement board self-weight receiving member 27 is arranged right above the longitudinal center of the through angle 24 and is lowered. As a result, the cement plate self-weight receiving member 27 is fitted and fixed to the vertical flange portion 24 a of the through angle 24. Thereafter, the cement plate self-weight receiving member 27 is fixed to the angle 24 by welding through the peripheral edge (FIGS. 43 and 44).

固着後、セメント板自重受け部材２７の水平フランジ部２８ｂに上段セメント板１９を載置させる。そして、連結金具６０の上縁部にＺクリップ４１の下部を嵌合係止させ、この状態で、上段セメント板１９にＺクリップ４１をボルト４４にて締付け固定する（図４５及び図４６）。すると、該Ｚクリップ４１の下部が前記通しアングル２４の鉛直フランジ部２４ａの外面部を挟んで締め付け固定する。斯くして、１本の通しアングル２４に、上下２段のセメント板１５，１９が強固に建て込まれ、実施例１と同様の効果を奏する。 After fixing, the upper cement plate 19 is placed on the horizontal flange portion 28 b of the cement plate self-weight receiving member 27. Then, the lower portion of the Z clip 41 is fitted and locked to the upper edge portion of the connection fitting 60, and in this state, the Z clip 41 is fastened and fixed to the upper cement plate 19 with bolts 44 (FIGS. 45 and 46). Then, the lower portion of the Z clip 41 is clamped and fixed by sandwiching the outer surface portion of the vertical flange portion 24a of the through angle 24. Thus, the upper and lower two-stage cement plates 15 and 19 are firmly built in one through angle 24, and the same effects as those of the first embodiment are obtained.

本発明において、通しアングルの鉛直フランジ部に嵌合溶接されるセメント板自重受け部材は、上記実施例１〜４の態様例に限定されものではなく、多様な応用変形例を適宜採択することができる。図４７及び図４８は他の態様例を示すものである。図示例の特徴は、下端外面に水平フランジ部６６ｂを有するセメント板自重受け部材６６の本体上部の左右方向Ｗ全域に、所定隙間Ｔ（鉛直フランジ部２４ａの厚み寸法と略同一の寸法）を有する縦断面Ｕ字形状を形成し、該Ｕ字形状部６７の隙間Ｔに、通しアングル２４の鉛直フランジ部２４ａを嵌合装着して挟持係止させるように構成したことにある。これによれば、セメント板自重受け部材６６の形状寸法が小さい場合でも、通しアングル２４に対する所要の連結強度を容易に確保できる。 In the present invention, the cement plate weight receiving member fitted and welded to the vertical flange portion of the through-angle is not limited to the above-described embodiments of the first to fourth embodiments, and various application modifications can be appropriately adopted. it can. 47 and 48 show another example. The illustrated example has a predetermined gap T (a dimension substantially the same as the thickness dimension of the vertical flange portion 24a) in the entire left and right direction W of the upper portion of the main body of the cement plate self-weight receiving member 66 having the horizontal flange portion 66b on the outer surface of the lower end. The vertical cross section is U-shaped, and the vertical flange portion 24a of the through angle 24 is fitted and mounted in the gap T of the U-shaped portion 67 so as to be clamped and locked. According to this, even when the shape dimension of the cement board own weight receiving member 66 is small, the required connection strength with respect to the through angle 24 can be easily ensured.

また、図４９はセメント板自重受け部材の更に他の態様例を示すものである。図示例の特徴は、水平フランジ部６９ｂを有するセメント板自重受け部材６９の本体上部の左右両側部のみにそれぞれ、所定隙間Ｔを有する縦断面Ｕ字形状を形成し、各Ｕ字形状部７０の隙間Ｔに、通しアングル２４の鉛直フランジ部２４ａを嵌合装着して挟持係止させるように構成したことにある。これによれば、セメント板自重受け部材６９の形状寸法が大きい場合でも、所要の連結強度を確保しつつセメント板自重受け部材６９の軽量化が図れる利点を有する。 FIG. 49 shows still another example of the cement plate weight receiving member. The feature of the illustrated example is that a U-shaped longitudinal section having a predetermined gap T is formed only on both the left and right sides of the upper part of the main body of the cement board own weight receiving member 69 having the horizontal flange portion 69b. The vertical flange portion 24a of the through angle 24 is fitted and mounted in the gap T so as to be sandwiched and locked. According to this, even when the shape dimension of the cement board own weight receiving member 69 is large, there is an advantage that the cement board own weight receiving member 69 can be reduced in weight while ensuring the required connection strength.

更に、本発明において、連結プレート及びＺクリップも、上記実施例１〜４の態様例に限定されものではなく、多様な応用変形例を適宜採択することができる。例えば、連結プレート及びＺクリップの位置関係は任意である。又、Ｚクリップに、通しアングル２４の鉛直フランジ部２４ａを挟み締め付けるための部材を重ねて、上段セメント板１９にボルト締めして固定してもよい。更に、逆Ｊ形係止部材５５の下部を段差状に形成し、該段差状部分を下段セメント板１９の上縁部に嵌合固定させることもできる。この係止部材５５の上部形状は、Ｊ形でなくとも通しアングル２４の鉛直フランジ部２４ａと嵌合する形状であれば任意の形状でもよい。 Furthermore, in this invention, a connection plate and Z clip are not limited to the example of the said Examples 1-4, A various application modification can be employ | adopted suitably. For example, the positional relationship between the connecting plate and the Z clip is arbitrary. Further, a member for sandwiching and tightening the vertical flange portion 24a of the through angle 24 may be overlapped on the Z clip, and the upper cement plate 19 may be bolted and fixed. Further, the lower portion of the inverted J-shaped locking member 55 can be formed in a step shape, and the stepped portion can be fitted and fixed to the upper edge of the lower cement plate 19. The upper shape of the locking member 55 is not limited to the J shape, but may be any shape as long as it fits with the vertical flange portion 24a of the through angle 24.
