Description

【０００１】
【産業上の利用分野】
本発明は、梁や桁等の横架材の柱や胴差等の構造材に対する接合装置に関するものである。
【０００２】
【従来の技術】
従来の、接合金具を用いた横架材（梁や桁）の接合装置としては、柱の側面に設けた受止穴に接合金具のプレート状の本体板の基端に突設した掛止材を嵌合掛止して組付けて前記本体板を柱側面より突出させ、この本体板に横架材の端部を端面に設けたスリットを係合させて組合わせるようにして前記スリットを通じて横架材の端部に予め横設した掛止杆を前記本体板に掛止して仮接合した後、横架材を通じて本体板に接合杆を嵌挿して接合するようにした構造のものがある（例えば、特許文献１参照）。

【発明が解決しようとする課題】
前記従来例は、接合金具の掛止材を受止するために柱側に特殊形状の受止穴を形成しなければならず、その加工が従来のほぞ接合のほぞ等と同様にきわめて煩雑で、接合金具を用いることによる利点である木材の加工上の簡便さを期待できない。また、柱側に組付けた接合金具のプレート体（プレート状本体）で横架材を受支する構成を採るため、いわば横架材の幅方向の１点で該横架材を受支することになるから、地震等の外力の付与に対処するにはその接合状態は必ずしも安定したものとはいえない。
【０００５】
本発明は、接合金具を用いることによる利点を生かし、横架材の安定した接合状態を得るべく創案したものである。
【０００６】
【課題を解決するための手段】
梁、桁などの横架材の端面に縦設した下端開口の係合溝に、該係合溝の相対する側壁のそれぞれに重ね合わせて止着して収設する一対の補強板と、該補強板の前記端面側の上部を通じて前記横架材の端部に横設する掛止杆と、この掛止杆を嵌合掛止する嵌合切欠を上端に備え、しかも、柱や胴差などの構造材の側面に突設する一対の受支板および該受支板を前記一対の補強板間に介在させて前記係合溝に摺嵌したとき、該受支板と前記補強板及び横架材の前記端部を互いに接合する接合杆とで構成することを基本的手段とし、補強板及び受支板の一方又は双方には該両板間の隙間を保持するための突縁を設けることにより両板間に生じる結露を防ぎ、結露を防ぎ、結露を原因とする装置全体の経時変化を防ぎ、堅牢な装置を提供する。
【０００７】
【発明の実施の形態】
図面は本発明に係る横架材の接合装置の実施形態を示し、図１は縦断面図、図２は横断面図、図３は図１の１Ａ−１Ａ線断面図、図４は補強板の斜視図、図５は接合金具の斜視図、図６は掛止杆又は接合杆と通しボルトとの関係に係る他の実施形態の説明図、図７は掛止杆又は接合杆と通しボルトとの関係に係るさらに他の実施形態の説明図である。
【０００８】
実施形態は、横架材（梁や桁）１側に補強板２を、柱（胴差でも良い）３側に接合金具４をそれぞれ止着し、補強板（鋼材で構成する）２と接合金具４で構成する受支板１７を掛止杆５と接合杆６とで組付けるようにして前記横架材１を柱３に接合するものである。
【０００９】
横架材１は端面に縦設した係合溝７を備え、該係合溝７内に収納するようにして一対の前記補強板２，２を止着、組付けたもので、係合溝７を方形状の大径部７ａと該大径部７ａの奥壁の両隅部にスリット状にして連通させた細径部７ｂ，７ｂとで構成し、この係合溝７の細径部７ｂに基端側を挟挿するようにして補強板２を係合溝７（大径部７ａ）の側壁７´の内側に重ね合わせ、補強板２の基端側に縦方向に並べて設けた各第一透孔８に、前記横架材１に前記係合溝細径部７ｂを横切るようにして前記第一透孔８と一致するように設けた第一嵌挿孔９を通じて固定杆１０を打込み、嵌挿して一対の補強板２，２を係合溝７内において空隙１１を存して組付けたものである。
【００１０】
また、横架材１に組付けた補強板２は、基（後）端側に縦方向に並べて設けた前記第一透孔８，８，８と同様に縦方向に並べて前端側に設けた第二透孔１２，１２Ａ，１２Ａを備え、これらを前記係合溝７の大径部７ａ部に配置して前記横架材１の係合溝大径部７ａ位置に前記第一嵌挿孔９，９，９と同様に縦方向に並べて設けた第二嵌挿孔１３，１３Ａ，１３Ａと一致させ、最上位の第二透孔１２に該第二透孔１２と一致する最上位の第二嵌挿孔１３を通じて前記掛止杆５を嵌挿して補強板２，２間に架設するようにして横架材１の係合溝大径部７ａ部位である先端部上部に横設してある。
【００１１】
前記柱３は、前記第二透孔１２，１２Ａ，１２Ａやこれらと一致する第二嵌挿孔１３，１３Ａ，１３Ａと対応するようにして縦方向に沿う中央に並べて設けた貫通孔１５，１５，１５を備え、該貫通孔１５に貫通させた通しボルト１４を利用してその側面に接合金具４を止着したものである。
【００１２】
接合金具４は、取付板１６の両側に一対の受支板１７，１７を相対設して成り、取付板１６には前記柱３に設けた貫通孔１５，１５，１５（該貫通孔１５に貫通させた通しボルト１４，１４，１４）のそれぞれと一致するようにして取付孔１８，１８，１８を縦方向に並べて設ける一方、受支板１７には上端の嵌合切欠１９と該切欠１９の直下に位置するようにして一対の接合孔２０，２０を設け、嵌合切欠１９を補強板２に設けた上位の前記第二透孔１２と、接合孔２０，２０を他の第二透孔１２Ａ，１２Ａと一致するように設けて構成したものである。
【００１３】
なお、受支板１７は実施形態のように接合金具４の一部で構成する必要はなく、鋼板のような単なるシート体で構成しても不都合はない。
【００１４】
また、接合金具４は、取付板１６に設けた取付孔１８，１８，１８のそれぞれに前記柱３の側面より前記貫通孔１５，１５，１５を利用して予め突出させた前記通しボルト１４の先端を挿通させるようにして柱３に組合わせ、通しボルト１４先端にワッシャー２１を介してナット２２を螺合締付けて柱３側面に固着して前記受支板１７を柱３側面より突出させたもので、柱３に対する接合金具４の、この取付け状態にあって、受支板１７に設けた嵌合切欠１９および一対の接合孔２０，２０のそれぞれに対応して前記通しボルト１４の先端が下側に近接して配置してある。
【００１５】
そして、補強板２，２およびこれらに架設するようにして配した掛止杆５を組付けた横架材１端部を、通しボルト１４およびナット２２によって柱３の側面に固着した接合金具４上に位置させて下方向に摺嵌（降下）させると、接合金具４を係合溝７すなわち補強板２，２間の空隙１１内に相対的に嵌合しつつ該横架材１は降下し、この降下に伴って嵌合切欠１９に掛止杆５が嵌合して嵌合切欠１９内を降下し、ついには、嵌合切欠１９の下縁で掛止杆５は受支され、該掛止杆５を組付けた横架材１は柱３に仮接合されることになる（このとき、掛止杆５は補強板２の第二透孔１２にも通してあるので、該掛止杆５に横架材１の全荷重が第二嵌挿孔１３部において負荷されることはなく、従って、補強板２は、この仮接合状態にあっても横架材１の第二嵌挿孔１３部からの損傷［裂傷］を防ぎ、補強材として機能する）。
【００１６】
この仮接合状態にあって、柱３側である接合金具４の受支板１７に設けた一対の接合孔２０，２０と、横架材１側である補強板２に設けた下側の一対の第二透孔１２Ａ，１２Ａおよびこれに一致させた横架材１の第二嵌挿孔１３Ａ，１３Ａは互いに一致した位置に配するようにしてあるから、これらに一方の第二嵌挿孔１３Ａ側から前記接合杆６を打込み嵌挿することによって横架材１は柱３に接合され、実施形態を適用した横架材の接合状態を得られる。
【００１７】
なお、柱３側である接合金具４の接合孔２０，２０の柱３側面からの離開距離より、横架材１側である第二透孔１２Ａ，１２Ａ（補強板２に設けた）や第二嵌挿孔１３Ａ，１３Ａの横架材１端面からの離開距離を短かくしておくと接合杆６をこれらに打込んで嵌挿する際に、横架材１が柱３方向に移動する引寄せ効果を期待でき、また、嵌合切欠１９を下縁方向に柱３側に漸次近づくように傾斜させると、掛止杆５がその傾斜に沿って移動することになるから、やはり、引寄せ効果を期待できる。
【００１８】
また、実施形態は補強板２の前端側に断面半円状の屈曲部片２ａ（省略しても良い）を設け、該屈曲部片２ａが圧接して弾性変形するように接合金具４の相対する受支板１７，１７の基部側である取付板１６側を、基部側から先端側方向に漸次互いに離開する平面視傾斜上の受圧部１７ａとなし、受支板１７，１７の上端を取付板１６より上方に突出させて相対する方向に折り曲げて案内部１７ｂ，１７ｂ´を設けてある。
【００１９】
実施形態にあっては、横架材１の端部を柱３に固着した接合金具４の直上に位置させて降下させると、接合金具４の受支板１７の案内部１７ｂ，１７ｂ´の存在によって補強板２，２間すなわち空隙１１内に接合金具４を係合しやすく、その作業を円滑に行うことができる。また、横架材１の端部を接合金具４に沿って降下させて掛止杆５を嵌合切欠１９に係合受支させての仮接合時に、補強板２側の屈曲部片２ａが受圧部１７ａを押圧して両者間に弾性が作用するので補強板２と接合金具４はよく密接してガタ付きがなく、次段の接合杆６の打込み操作などを円滑に行うことができる。
【００２０】
なお、図６および図７は、掛止杆５又は接合杆６と通しボルト１４との関係の説明図を示し、図６は掛止杆５又は接合杆６を通しボルト１４と接する直上に配置して横架材１の荷重を掛止杆５や接合杆６を介して通しボルト１４によっても受けるようにしてより強固な接合状態を得られるようにしたものである。
【００２１】
図７の場合は、掛止杆５又は接合杆６を図９のようにするのと同時に、ナット２２と接する位置に配してナット２２の緩み止めも機能させようとしたものである。
【００２２】
いずれにしても、掛止杆５や接合杆６は通しボルト１４とナット２２との接触位置（図６や図７）に在ることが望ましく、接触位置に存することにより、前記の通り接合強度の優れた装置を得られると共に、図１乃至図４の実施形態で掛止杆５や接合杆６として用いたドリフトピンの受支板１７に設けた切欠１９又は接合孔２０や補強板２に設けた第二透孔１２又は１２Ａ或いは横架材１に設けた第二嵌挿孔１３又は１３Ａを通じての嵌挿打込み操作時における当該ドリフトピンの案内材にもなるのである。
【００２３】
図６や図７で示す掛止杆５又は接合杆６と通しボルト１４との関係は、柱３側の通しボルト１４を貫通させる貫通孔１５と掛止杆５や接合杆６を貫通させる前記接合孔２０（又は切欠１９）、第二透孔１２（又は１２Ａ）および第二嵌挿孔１３（又は１３Ａ）が互いに当該関係位置に存することを前提とすることは勿論である。また、掛止杆５と接合杆６の全部がそれぞれ通しボルト１４やナット２２との配置関係で図６や図７の状態になくとも良く、その一部が図６や図７の状態であっても良い。
【００２４】
図示２８は、前記横架材１の荷重を受ける前記受支板１７の外側面の適所に設けた突子（補強板２側にも設けても良いし、補強板２側にのみ設けても良い）で、該突子２８の存在によって受支板１７と前記補強板２との間に隙間が形成され、金物である受支板１７と補強板２との密着（接）を防ぎ、密着による結露を防止し、結露水を原因とする補強板等の機能の劣化を防止できる。
【００２５】
実施形態にあっては屈曲部片２ａが構成する突縁も間隙保持を機能する。
【００２６】
【発明の効果】
本発明は前記の通りの構成であるから、横架材などの木材側に複雑な加工を施こさず、補強板等の金具を木材側に簡単に組付けられる斬新な構造の接合装置を提供でき、しかも、補強板の存在によって掛止杆や接合杆を横架材の端面に近接して配することができ、このため受支板の構造材からの突出量を低減できるから、全体として耐久的な横架材の接合装置を提供できる。

[0004]
[Problems to be solved by the invention]
In the conventional example, a receiving hole having a special shape must be formed on the column side in order to receive the latching material of the joining metal fitting, and the processing is extremely complicated like the tenon for the conventional tenon joining. The convenience in processing wood, which is an advantage of using the joining metal fitting, cannot be expected. Further, since the horizontal member is supported by the plate body (plate-shaped main body) of the joint fitting assembled on the column side, the horizontal member is supported at one point in the width direction of the horizontal member. Therefore, in order to cope with the application of an external force such as an earthquake, the joint state is not necessarily stable.
[0005]
The present invention has been devised in order to obtain a stable joint state of the horizontal member by taking advantage of the joint metal fitting.
[0006]
[Means for Solving the Problems]

[0020]
6 and 7 are explanatory views of the relationship between the latching rod 5 or the joint rod 6 and the through-bolt 14, and FIG. 6 is arranged immediately above the latch bolt 5 or the joint rod 6 in contact with the through-bolt 14. Thus, the load of the horizontal member 1 is also received by the through bolts 14 through the latching rods 5 and the joining rods 6 so that a stronger joining state can be obtained.
[0021]
In the case of FIG. 7, the latch rod 5 or the joint rod 6 is arranged as shown in FIG. 9 at the same time as the nut 22 so that the nut 22 can be prevented from loosening.
[0022]
In any case, it is desirable that the latching rod 5 and the joining rod 6 are located at the contact position (FIGS. 6 and 7) between the through bolt 14 and the nut 22, and as a result, the joining strength is as described above. 1 to 4, the notch 19 provided in the support plate 17 of the drift pin used as the latch rod 5 or the joint rod 6 in the embodiment of FIGS.

[0023]
The relationship between the latching rod 5 or the joining rod 6 and the through bolt 14 shown in FIGS. 6 and 7 is such that the through hole 15 that penetrates the through bolt 14 on the column 3 side and the latch rod 5 and the joining rod 6 are penetrated. Of course, it is assumed that the joining hole 20 (or the notch 19), the second through hole 12 (or 12A), and the second fitting insertion hole 13 (or 13A) are located at the relevant positions. Further, the latch rod 5 and the joint rod 6 may not be in the state of FIGS. 6 and 7 due to the arrangement relationship of the through bolts 14 and the nuts 22 respectively, and some of them are in the state of FIGS. 6 and 7. May be.
[0024]
28 is a protrusion provided at a suitable position on the outer surface of the support plate 17 that receives the load of the horizontal member 1 (may be provided on the reinforcing plate 2 side or only on the reinforcing plate 2 side). Therefore, a gap is formed between the support plate 17 and the reinforcing plate 2 due to the presence of the protrusions 28 to prevent close contact (contact) between the support plate 17 and the reinforcing plate 2, which are metal objects.
