Description

【０００１】
【産業上の利用分野】
本発明は、木造建物の梁、桁などの横架材を、柱や胴差などの構造に接合するために適用する横架材の接合装置に関するものである。
【０００２】
【従来の技術】
取付板と該取付板の前面に突設した接合板とで接合金物を構成し、該接合金物の取付板を柱や胴差などの構造材にボルト締めして前記接合板を構造材に突設し、該接合板を梁、桁などの横架材の端面に縦設したスリットに係合するようにして横架材端部を前記接合金物に設けた透孔に横架材を通じてドリフトピンを嵌挿させるようにして横架材を構造材に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）。

【発明が解決しようとする課題】
前記公報記載の構造のものは、構造材の側面に接合金具を取付け、該接合金具に対して横架材の端面に設けたスリットを係合して接合することを基本とするため、プレカット工場等の工場からの出荷時には構造材である木材の側面より接合金具が突出した状態にあると運搬、取扱上不便であるため、現場で接合金具を木材に取付ける必要があり、そのため現場では騒音、工期の長期化等様々な不都合が生じる。
【０００５】
本発明は、斯様な従来例の欠点に着目して創案し、しかも、横架材の確実な接合を行うことのできる装置を提供すべく創案したものである。
【０００６】
【課題を解決するための手段】
梁などの横架材の端部に、その端面に縦設した下端開口の係合溝の相対する各側壁に重ね合わせ、かつ、互いに間隙を存して補強板を止着し、該補強板を通じて第一掛止杆を横架材の前記端部の上部側に横設し、この第一掛止杆を前記間隙内で受支する、大径な先端部を備えた第一突子と、該第一突子より下側にして前記下端開口部を通じて前記間隙内に位置させる、適宜数の、大径な先端部を備えた第二突子を、柱や胴差などの構造材の側面に突設し、前記第二突子に掛止する第二掛止杆と、前記第一突子と第二突子の一方又は双方の下側にそれぞれ位置させて該突子を前記第一又は第二の掛止杆とで挟持する係止杆のそれぞれの嵌挿孔を、横架材の前記端部の側面に、前記補強板に設けた係止杆貫通用の透孔と一致するように横設した構成とすることを基本的手段とし、この手段に、第一突子と第二突子のそれぞれの先端部の後端側の周側に、前記先端部の先端方向に漸次大径とするテーパ縁を設け、このテーパ縁と接する位置に第一、第二の掛止杆と係止杆および係止片の全部又は一部を配置したことを付加すれば、接合時に横架材の構造材方向への引き寄せを図ることができる。
【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一実施形態を示し、図１は縦断面図、図２は横断面図、図３は補強板の斜視図である。
【０００８】
実施形態の接合装置は、横架材（実施形態では梁であるが桁でも良い）１側に一対の補強板２，２を取付け（固定し）、該補強板２，２を通じて前記横架材１の端部に嵌挿する第一、第二の掛止杆３，３Ａや係止杆４を、構造材（実施形態では柱であるが胴差でも良い）１０側に設けた第一、第二の突子５，５Ａと互いに組合わせて前記横架材１を構造材１０に接合するものである。
【０００９】
補強板２は鋼板製の平板体で成り、先端部に一対三組の第一透孔６，６、６，６、６，６を、後端部に３個の第二透孔６Ａ，６Ａ，６Ａをそれぞれ上下対称的に設けて左右勝手方向を選択して自在に使用できるようにしたものである。
【００１０】
もっとも、実施形態の補強板２は、横架材１の長手方向（端面）に面して左右いずれの側にも適用できるようにして当該補強板１の製造コストや在庫管理費の低減を図ったものであるが、これらの点を無視すれば、左右勝手それぞれ専用の補強板（例えば、透孔６，６Ａ位置を上下非対称的に設けて）を用いても不都合はない。
【００１１】
なお、前記一対三組の第一透孔６，６、６，６、６，６は各組において上位側のものが常に用いられ、下位側のものも常に用いて差し支えないが（この場合は、係止杆４貫通用として用いる）、図１で示す通り、実施形態では最下位の組の下位側のもの（左右勝手を選択して適用方向を決めた当該補強板２の）みを用いている。
【００１２】
前記横架材１の端部１´の側面には、補強板２の先端部側に設けた前記各組の第一透孔６，６中の上位側のもの６と一致する位置にして第一嵌挿孔７，７，７を設け、該第一嵌挿孔７，７，７中の最下位の第一嵌挿孔７（便宜上、符号７ａで示す）の下側には該嵌挿孔７（符号７ａで示す）と対応する前記第一透孔６（便宜上、符号６ａで示す）と前記一組を成す下位側の透孔６（便宜上、符号６ｂで示す）と一致する位置にして他の第一嵌挿孔７（便宜上、符号７ｂで示す）を設ける一方、前記端部１´の側面の後端側には前記組付片５の後端部側に設けた第二透孔６Ａ，６Ａ，６Ａと一致する位置にして第二嵌挿孔７Ａ，７Ａ，７Ａを横設してある。
【００１３】
また、横架材１の端面１ａには、これら嵌挿孔７，７Ａと交叉するようにして下端開口の係合溝（縦溝）８を設け、係合溝８は、構造材１０側に突設した前記第一突子５と第二突子５Ａが係合できる奥行幅を有する溝部８ａと該溝部８ａの奥壁の両隅部に溝部８ａを部分的に延長させて設けた一対のスリット部８ｂ，８ｂで構成し、この係合溝８に勝手方向を選択した一対の前記補強板２，２を該係合溝８の各側壁に重ね合わせるようにして係合して前記の通り横架材１（の端部１´）に互いに間隙ｂを存して固定してある。すなわち、補強板２は、後端部を係合溝８のスリット部８ｂに嵌挿させて先端部を溝部８ａに配するようにして後端部側に設けた第二透孔６Ａと横架材１側に設けた第二嵌挿孔７Ａを一致させ、これらにドリフトピンで構成した固定杆９を、また、互いに一致する第一透孔６と第一嵌挿孔７同士中の最上位のものにドリフトピンで構成した最上位の掛止杆である第一掛止杆３をそれぞれ打ち込み、嵌挿して横架材１端部に互いに間隙ｂを存して固定してある。
【００１４】
前記第一、第二の各突子５，５Ａは、前記構造材１０を貫通させ、構造材１０より突出させた螺子部１１にナット１２を螺合して取付けたボルト杆１３の頭部側で構成し、構造材１０の側面（横架材１との対向面）に、前記間隙ｂ或いは第一透孔６や第一嵌挿孔７と相対的に設定される位置関係にして縦方向に並設され、第一突子５は前記第一掛止杆３（最上位の第一透孔６や第一嵌挿孔７）と、第二突子５Ａは最上位のものを除く他の第一透孔６（６ａ，６ｂ）や最上位のものを除く他の第一嵌挿孔７（７ａ，７ｂ）とそれぞれ一致するようにして構造材１０に突設したものである。
【００１５】
突子５，５Ａの大径な（中間部より大きな径のある部分を備えた）先端部（ボルト杆１３の頭部で構成する）５´，５´Ａの後端側の周側に備えたテーパ縁ａ，ａ´（円錐台形体で構成した）は、横架材１の構造材１０方向への引寄せ作用をするもので、第一突子５のテーパ縁ａに第一掛止杆３が載ったとき、その傾斜により該掛止杆３は降下しつつ構造材１０方向へ移動し、補強板２を取付けた横架材１は構造材１０方向へ引き寄せられることになり、また、第二突子５Ａのテーパ縁ａ´の場合は、該テーパ縁ａ´の一部が重なり合うようにして接合金具Ａに設けた第一透孔６（６ａ，６ｂ）（最上位のものを除く）に第二掛止杆３Ａ又は係止杆４を挿通させたとき、掛止杆３Ａ又は係止杆４がテーパ縁ａ´を相対的に押圧して第一透孔６（６ａ，６ｂ）に挿通されることになり、第二掛止杆３Ａ等により押圧されたテーパ縁ａ´すなわち第二突子５Ａは定置状態にあるから第二掛止杆３Ａ等を組付けた横架材１側が構造材１０方向に移動することになり、横架材１は構造材１０方向へ引き寄せられることになる。
【００１６】
なお、実施形態の突子５，５Ａの先端部５´，５´Ａは、前記の通り、ボルト杆１３の頭部で構成してあるが、これは突子５，５Ａの中間部を挟持する掛止杆３又は３Ａと係止杆４との離開幅（距離）より、先端部５´，５´Ａが常時幅広い大径な状態位置に配することができるからで（ボルト杆１３は回転方向においてはどの回転角度でも径の変化はない）、つまり、方向性を選ぶ必要がないからで、この意味において、突子５，５Ａ（ボルト杆１３）を構造材１０に取付けるに際しての煩雑さは回避できる。従って、この煩雑さを無視すれば、突子５，５Ａの先端部５´，５´Ａは、その上端と下端のみを突出させた、側面視ほぼＴ字形のものでも不都合はなく、テーパ縁は省略しても良い。
【００１７】
そして、横架材１に固着した補強板２，２間の間隙ｂに構造材１０に突設した第一突子５及び第二突子５Ａが、係合溝の下端開口部を通じて相対的に係合するようにして横架材１を構造材１０の側面に沿って降下させると、間隙ｂの上部側に配した第一掛止杆３が第一突子５に掛止し、横架材１は第一突子５に掛止杆３を介して受止されて構造材１０に仮接合される。この状態で互いに連通状態に有る第一透孔６（６ａ，６ｂ）と第一嵌挿孔７に第二掛止杆３Ａを打ち込み、嵌挿すると、第二掛止杆３Ａは横架材１に横設、固定され第二突子５Ａに受止される位置に配され、横架材１側の荷重を第二突子５Ａに負荷させ、耐荷重強度を得られる。
【００１８】
また、第二掛止杆３Ａの打込み操作と相前後して最下位の第一透孔６（符号６ｂで示している）と第一嵌挿孔７（符号７ｂで示す）に前記係止杆４を打ち込み、嵌挿させると、係止杆４は最下位の第二突子５Ａの下縁に接する位置にして横架材１に横設され、横架材１に下方から外力が負荷したとき、係止杆４が最下位の第二突子５Ａに係止して横架材１の浮き上りが防止される状態になると同時に、最下位の第二突子５Ａは係止杆４と第二掛止杆３Ａとでその中間部を挟持された状態になるので、横架材１に対して構造材１０から離開する方向の外力が負荷しても、第二突子５Ａの大径な先端部５´Ａの存在によって前記の挟持状態が維持され、横架材１の構造材１０からの離脱が防止される状態にもなるのである。
【００１９】
実施形態の場合は、図示６ａで示す第一透孔および７ａで示す第一嵌挿孔に嵌挿した第二掛止杆３Ａに対応する、図示６ｂで示す第一透孔および７ｂで示す第一嵌挿孔に嵌挿した係止杆４のみを係止杆として用いているが、構造材１に突設した各突子５，５Ａ全部を係止杆４と掛止杆３又は３Ａで挟持させるようにすれば、構造材１０に作用する横架材１からの離脱方向への外力に、尚一層対処することができる。
【００２０】
なお、第二突子５Ａ（これに対応する第一透孔６や第一嵌挿孔７）の数は適宜選択すれば良く、適宜数のものを選択して利用しても良く、また、第一、第二の掛止杆３，３Ａは各突子（実施例では第一突子５と第二突子５Ａの全部）の全部又は適宜のものに対応させて設けても良い（実施例の配置に限定する必要はない）。係止杆４については前記の通りである。
【００２１】
なお、図１７は、ボルト杆１３の頭部側（突子５，５Ａ側）に設けた係止鍔で、該係止鍔１７が構造材１０の側面に係止することにより各突子５，５Ａを一定の突出量を備えた、設計通りの位置に配することができるのである。
【００２２】
【発明の効果】
本発明は前記の通り、従来のように接合金具の存在による運搬上の不都合が生じることがなく、横架材を構造材に確実に接合することのできる斬新な構造の接合装置を提供できる。また、本発明にあっては、横架材に補強板を設けて該補強板を通じて前記横架材に掛止杆や係止杆を嵌挿するようにしているため、該掛止杆等を介する外力が横架材に負荷してもその損傷を防ぐことができ、従って、掛止杆等を構造材に近接させて配せられ、必然的に構造材側の突子の突出量を低減でき、突出量の大きいことによる突子の耐力の低下を防げ、総じて横架材の接合状態を簡単な構造で確実に維持できる装置を提供できる。

[0007]
DETAILED DESCRIPTION OF THE INVENTION
The drawings show an embodiment of a horizontal member joining apparatus according to the present invention. FIG. 1 is a longitudinal sectional view, FIG. 2 is a transverse sectional view, and FIG. 3 is a perspective view of a reinforcing plate.
[0008]
In the joining device of the embodiment, a pair of reinforcing plates 2 and 2 are attached (fixed) to a horizontal member (in the embodiment, a beam but may be a girder) 1 side, and the horizontal member is passed through the reinforcing plates 2 and 2. The first and second latching rods 3 and 3A and the locking rods 4 to be inserted into the end of 1 are provided on the side of the structural material 10 (which is a column in the embodiment but may be a torso), The horizontal member 1 is joined to the structural member 10 in combination with the second protrusions 5 and 5A.
[0009]
The reinforcing plate 2 is made of a flat plate made of a steel plate, with a pair of first through holes 6, 6, 6, 6, 6, 6 at the front end and three second through holes 6A, 6A at the rear end. 6A are provided symmetrically in the vertical direction so that they can be used freely by selecting the right and left direction.
[0010]
However, the reinforcing plate 2 of the embodiment faces the longitudinal direction (end surface) of the horizontal member 1 and can be applied to either the left or right side in order to reduce the manufacturing cost and inventory management cost of the reinforcing plate 1. However, if these points are ignored, there is no inconvenience even if a dedicated reinforcing plate for each of the left and right sides (for example, the positions of the through holes 6, 6A are provided asymmetrically in the vertical direction) is used.
[0011]
The first through holes 6, 6, 6, 6, 6 and 6 of the pair are always used in the upper side in each set, and the lower side may be used in all cases (in this case, , Used for penetrating the locking rod 4), as shown in FIG. 1, in the embodiment, the lower side of the lowest pair (of the reinforcing plate 2 that selects the right and left hand and determines the application direction) is used ing.
[0012]
On the side surface of the end portion 1 ′ of the horizontal member 1, a position that coincides with the upper one 6 in the first through holes 6, 6 of each set provided on the tip end side of the reinforcing plate 2 is arranged. One insertion hole 7, 7, 7 is provided, and the lowermost first insertion hole 7 (indicated for convenience by reference numeral 7 a) in the first insertion hole 7, 7, 7 The first through hole 6 (indicated by reference numeral 6a for convenience) corresponding to the hole 7 (indicated by reference numeral 7a) and the lower side through hole 6 (indicated by reference numeral 6b for convenience) corresponding to the set are aligned with each other. The other first fitting insertion hole 7 (indicated by reference numeral 7b for convenience) is provided, while the rear end side of the side surface of the end portion 1 ′ is provided with a second through hole provided on the rear end portion side of the assembly piece 5. Second fitting insertion holes 7A, 7A, 7A are provided laterally at positions corresponding to the holes 6A, 6A, 6A.
[0013]
In addition, the end surface 1a of the horizontal member 1 is provided with an engaging groove (vertical groove) 8 having a lower end opening so as to intersect with the fitting insertion holes 7 and 7A, and the engaging groove 8 is provided on the structural material 10 side. A pair of grooves 8a having a depth that can be engaged with the projecting first and second protrusions 5A and 5A and the corners of the inner wall of the groove 8a are partially extended. A pair of the reinforcing plates 2 and 2 which are configured by the slit portions 8b and 8b and whose direction is selected are engaged with the engaging groove 8 so as to overlap each side wall of the engaging groove 8 as described above. The horizontal member 1 (the end 1 ') is fixed with a gap b between each other. That is, the reinforcing plate 2 is horizontally mounted with the second through-hole 6A provided on the rear end side such that the rear end portion is fitted into the slit portion 8b of the engagement groove 8 and the front end portion is disposed in the groove portion 8a. 7A of 2nd insertion holes provided in the material 1 side are made to correspond, and the fixing rod 9 comprised by these with the drift pin is also the highest position in 1st through-hole 6 and 1st insertion insertion holes 7 which mutually correspond. The first latch rod 3 which is the uppermost latch rod composed of drift pins is driven into each of them, and is inserted and fixed at the end of the horizontal member 1 with a gap b between them.
[0014]
Each of the first and second protrusions 5 and 5 </ b> A penetrates the structural member 10, and the head side of a bolt rod 13 attached by screwing a nut 12 to a screw portion 11 protruding from the structural member 10. In the longitudinal direction, the positional relationship is set relatively to the gap b or the first through-hole 6 or the first insertion hole 7 on the side surface of the structural member 10 (the surface facing the horizontal member 1). The first protrusion 5 is the same as the first latching rod 3 (the uppermost first through-hole 6 and the first fitting insertion hole 7), and the second protrusion 5A is other than the uppermost one. The first through-hole 6 (6a, 6b) and the other first fitting insertion holes 7 (7a, 7b) other than the uppermost one are projected from the structural member 10 respectively.
[0015]
Provided on the peripheral side of the rear end side of 5 ′, 5′A of the protrusions 5, 5 A (having a portion having a larger diameter than the intermediate portion) 5 ′, 5′A. The taper edges a and a ′ (configured by a truncated cone) act to draw the horizontal member 1 in the direction of the structural material 10, and the first hook 5 is attached to the taper edge a of the first protrusion 5. When the rod 3 is placed, the latch rod 3 moves downward while moving toward the structural material 10, and the horizontal member 1 to which the reinforcing plate 2 is attached is pulled toward the structural material 10. In the case of the taper edge a ′ of the second protrusion 5A, the first through holes 6 (6a, 6b) (the uppermost one provided in the joint fitting A so that a part of the taper edge a ′ is overlapped). When the second latching rod 3A or the latching rod 4 is inserted into the first through hole 6 (6), the latching rod 3A or the latching rod 4 relatively presses the taper edge a ′. 6b), and the taper edge a 'pressed by the second hook 3A or the like, that is, the second protrusion 5A is in a stationary state. The frame material 1 side moves in the direction of the structural material 10, and the horizontal material 1 is drawn toward the direction of the structural material 10.
[0016]
In addition, as above-mentioned, although the front-end | tip parts 5 'and 5'A of the protrusions 5 and 5A of the embodiment are comprised by the head of the bolt rod 13, this clamps the intermediate part of the protrusions 5 and 5A. This is because the distal end portions 5 'and 5'A can always be arranged in a wide and large diameter position from the separation width (distance) between the retaining rod 3 or 3A and the locking rod 4 (the bolt rod 13 is There is no change in the diameter at any rotation angle in the rotation direction), that is, there is no need to select the directionality. In this sense, it is troublesome to attach the protrusions 5 and 5A (bolt rod 13) to the structural member 10. This can be avoided. Accordingly, if this complexity is ignored, the tip portions 5 'and 5'A of the protrusions 5 and 5A may be substantially T-shaped in a side view in which only the upper and lower ends protrude, and there is no problem. May be omitted.
[0017]
And the 1st protrusion 5 and 2nd protrusion 5A which protruded in the structural material 10 in the gap | interval b between the reinforcement plates 2 and 2 adhering to the horizontal member 1 are relatively passed through the lower end opening of the engaging groove. When the horizontal member 1 is lowered along the side surface of the structural member 10 so as to be engaged, the first hooking rod 3 disposed on the upper side of the gap b is hooked on the first protrusion 5, and the horizontal member is mounted. The material 1 is received by the first protrusion 5 via the hook 3 and temporarily joined to the structural material 10. In this state, when the second hooking rod 3A is driven into the first through holes 6 (6a, 6b) and the first fitting insertion hole 7 which are in communication with each other, and inserted, the second hooking rod 3A becomes the horizontal member 1. The load is applied to the second projecting member 5A by applying the load on the horizontal member 1 side to the second projecting member 5A.
[0018]
The locking rod is inserted into the lowest first through hole 6 (indicated by reference numeral 6b) and the first fitting insertion hole 7 (indicated by reference numeral 7b) at the same time as the driving operation of the second hooking rod 3A. 4 is driven and inserted, the locking rod 4 is placed horizontally on the horizontal member 1 at a position in contact with the lower edge of the lowest second protrusion 5A, and external force is applied to the horizontal member 1 from below. At the same time, the locking rod 4 is locked to the lowermost second protrusion 5A to prevent the horizontal member 1 from being lifted, and at the same time, the lowermost second protrusion 5A is connected to the locking rod 4. Since the intermediate portion is sandwiched between the second hooks 3A, even if an external force is applied to the horizontal member 1 in a direction away from the structural member 10, the second protrusion 5A has a large diameter. The presence of the leading end portion 5′A maintains the above-described sandwiched state, and also prevents the horizontal member 1 from being detached from the structural member 10.
[0019]
In the case of the embodiment, the first through-hole shown in FIG. 6b and the first through-hole shown in 7b corresponding to the second retaining rod 3A inserted into the first through-hole shown in FIG. Although only the locking rod 4 inserted into the one insertion hole is used as the locking rod, all the protrusions 5 and 5A projecting on the structural material 1 are connected with the locking rod 4 and the latching rod 3 or 3A. If sandwiched, the external force acting on the structural member 10 in the direction of detachment from the horizontal member 1 can be dealt with even more.
[0020]
The number of the second protrusions 5A (the first through holes 6 and the first fitting insertion holes 7 corresponding thereto) may be appropriately selected, and an appropriate number may be selected and used. The first and second latching rods 3 and 3A may be provided corresponding to all or appropriate ones of the protrusions (all of the first protrusion 5 and the second protrusion 5A in the embodiment). It need not be limited to example placement). The locking rod 4 is as described above.
[0021]
FIG. 17 shows a locking rod provided on the head side (projections 5 and 5 </ b> A side) of the bolt rod 13. When the locking rod 17 is locked to the side surface of the structural member 10, each projection 5 , 5A can be arranged at a designed position with a certain amount of protrusion.
[0022]
【The invention's effect】
As described above, the present invention can provide a joining apparatus having a novel structure capable of reliably joining a horizontal member to a structural member without causing inconvenience in transportation due to the presence of a joining metal fitting as in the prior art. In the present invention, a reinforcing plate is provided on the horizontal member, and a latching rod or a locking rod is inserted into the horizontal member through the reinforcing plate. Even if the external force is applied to the horizontal member, it can be prevented from being damaged. Therefore, hooks and so on can be placed close to the structural material, which inevitably reduces the amount of protrusion on the structural material side. It is possible to provide a device that can prevent a decrease in the yield strength of the protrusion due to a large protrusion amount and can reliably maintain the joined state of the horizontal member as a whole with a simple structure.
