Description

本発明は、木造建築において横架部材（梁、桁、土台等）を主幹部材（柱、及び梁や桁、胴差し等の横架部材）に対して任意の角度で斜めに連結できる連結金具に関する。   The present invention provides a connecting bracket that can connect a horizontal member (beam, girder, foundation, etc.) obliquely at an arbitrary angle to a main member (column, horizontal member such as a beam, girder, girder, etc.) in a wooden building. About.

道路の関係などで部屋の形を平面視四角形以外の形、例えば平面視台形状等とする場合には、梁等の横架部材を柱等の主幹部材に対して斜めに連結する必要がある。そのための連結金具としては、横架部材の端部に形成したスリットに差し込まれる接続片と、接続片から突出する形で形成され、主幹部材の接合面に形成した嵌合穴に嵌まり込む突起体とで構成したものが知られている（例えば特許文献１参照。）。
特開平１１−１７２７８８号公報 When the shape of the room is a shape other than a square in plan view, such as a plan view trapezoidal shape due to roads, etc., it is necessary to connect a horizontal member such as a beam obliquely to a main member such as a column. . As a connecting metal fitting for that purpose, a connecting piece inserted into a slit formed at the end of the horizontal member, and a protrusion formed in a shape protruding from the connecting piece and fitted into a fitting hole formed in the joining surface of the main member The thing comprised with the body is known (for example, refer patent document 1).
JP-A-11-172788

上記連結金具は、接続片を横架部材の長手方向に平行に埋め込むため、横架部材の連結角度が変われば接続片の角度も変わってくるので、横架部材の連結角度に合わせて一つ一つ特注で生産しなければならず、納期やコストが大となっている。また上記連結金具は、建築現場において主幹部材に一つ一つ取り付けるのは煩雑であるため、木材のプレカット工場で主幹部材に予め取り付けておくのが普通である。そうすると、工場から建築現場まで主幹部材を運搬する際、金具の接続片が主幹部材から飛び出すために荷嵩が増え、輸送コストが増大する不都合があった。   Since the connecting piece embeds the connecting piece parallel to the longitudinal direction of the horizontal member, if the connecting angle of the horizontal member changes, the angle of the connecting piece also changes. One special order must be produced, leading to large delivery times and costs. Moreover, since it is cumbersome to attach the above-mentioned metal fittings one by one to the main member at the construction site, it is usually attached in advance to the main member in a wood pre-cut factory. Then, when the main member is transported from the factory to the construction site, the connection piece of the metal fitting jumps out of the main member, resulting in an inconvenience that the bulk is increased and the transportation cost is increased.

さらに上記連結金具は、横架部材に固定する部分である接続片と、主幹部材に固定する部分である突起体とが一体になっていることで、以下のような不都合があった。
連結金具は、先に述べたように工場で主幹部材に予め取り付ける関係上、連結金具を上下に分離する主幹部材に跨って設置することができない。例えば柱と胴差しとが連結する箇所に、側方から背の高い梁の端面を当接して接合するような場合に、連結金具を柱と胴差しとに跨って設置することができず、また、連結金具を上下に分割する形で設置するのは連結強度の面から好ましくなく、そのため胴差しの背丈を梁の背丈と同じにして一体の連結金具を用いるようにしている。しかし、胴差しは途中を柱で受けているので、梁よりも背丈の低い木材を用いても強度上は問題がない。すなわち、従来の金具では背丈の低い横架部材の側面に背丈の高い横架部材の端面を当接して連結することができないため、互いに接合される横架部材の背丈を高い方の背丈に共通させており、金具の利用をしやすくするために経済性を多少犠牲にしていた。 Furthermore, the connection fitting has the following inconvenience because the connecting piece, which is a portion fixed to the horizontal member, and the protrusion, which is a portion fixed to the main member, are integrated.
As described above, the connecting bracket cannot be installed across the trunk member that separates the connecting bracket in the vertical direction because it is attached to the trunk member in advance at the factory. For example, in the case where the end face of a tall beam is abutted and joined from the side to the place where the pillar and torso are connected, the connecting bracket cannot be installed across the pillar and torso, In addition, it is not preferable to install the connecting brackets in a vertically divided manner from the viewpoint of connection strength. For this reason, an integral connecting bracket is used with the height of the torso being the same as that of the beam. However, since the torso is received by a pillar in the middle, there is no problem in strength even if wood whose height is lower than the beam is used. In other words, with conventional brackets, the end face of a horizontal member with a high height cannot be connected to the side surface of a horizontal member with a low height, so the horizontal height of the horizontal members to be joined together is common to the higher height In order to make the metal fittings easier to use, some economics were sacrificed.

また、最新の木造建築用ＣＡＤ・ＣＡＭシステムでは、連結金具に関する情報がインプットされていて、躯体の組立図面を作図すると、各部材のどこにどの連結金具を用いて、各部材にどのような取付け用の穴加工をしなければならないかを認識し、各部材に画一的な穴加工が自動的になされるようにしている。しかし個々の木造建築によっては、床上に置く畳の厚みが違っていたり、あるいはフローリングの床であったりするために、梁が柱等に取付く高さを上下に変更したい場合があるが、そのような設計変更に対応して穴位置が逐一自動的に変えられるようにソフトウエアを整備するのは容易ではなく、手作業で穴加工を行うのも煩雑であった。   In addition, in the latest CAD / CAM system for wooden buildings, information on connecting brackets has been input, and when drawing the assembly drawings of the housing, which connecting bracket is used for each member, what kind of mounting is used for each member Recognizing whether it is necessary to drill holes, uniform drilling is automatically performed on each member. However, depending on the individual wooden construction, the thickness of the tatami placed on the floor may be different, or the floor may be a flooring floor. It is not easy to prepare the software so that the hole position can be automatically changed one by one in response to such a design change, and it is complicated to perform the hole processing manually.

本発明は以上に述べた実情に鑑みてなされたものであって、主幹部材に横架部材を任意の角度で連結することができ、予め主幹部材に取付けておいても金具が邪魔にならず、さらに木造躯体の施工性と経済性の向上にも寄与する木造建築部材の連結金具の提供を目的とする。   The present invention has been made in view of the above-described circumstances, and a horizontal member can be connected to the main trunk member at an arbitrary angle, and the metal fitting does not get in the way even if attached to the main trunk member in advance. Furthermore, it aims at providing the connection metal fitting of the wooden building member which contributes also to the improvement of the construction property and economical efficiency of a wooden frame.

上記の課題を達成するために、請求項１記載の発明による木造建築部材の連結金具は、主幹部材に取付けるベース金具と、横架部材の端部に形成したスリットに差し込む板状の接続金具と、ベース金具と接続金具とを連結する連結ピンとを備え、接続金具は、主幹部材側の端部を連結ピンによりベース金具に連結してあり、連結ピンを支点として回動可能であり、且つ接続金具は、別々の主幹部材に取付けた複数のベース金具に跨って連結自在であることを特徴とする。 In order to achieve the above object, a connecting member for a wooden building member according to the invention described in claim 1 includes a base member attached to the main member, a plate-like connecting member inserted into a slit formed at an end of the horizontal member, , A connecting pin for connecting the base metal fitting and the connection metal fitting, and the connection metal fitting is connected to the base metal fitting by the connection pin at the end on the main member side , and can be rotated using the connection pin as a fulcrum. The metal fitting is characterized in that it can be connected across a plurality of base metal fittings attached to different main trunk members .

請求項１記載の発明による連結金具は、横架部材端部のスリットに差し込む接続金具が、連結ピンを支点として回動可能となっているので、横架部材を任意の角度で主幹部材に斜めに連結できる。また、本連結金具を予め工場で主幹部材に取付けても、接続金具が主幹部材の側面に沿うように倒れるので、主幹部材を工場から建築現場に運ぶ際に金具が邪魔にならない。   In the connecting bracket according to the first aspect of the present invention, the connecting bracket to be inserted into the slit at the end of the horizontal member is rotatable with the connecting pin as a fulcrum, so that the horizontal member is inclined to the main member at an arbitrary angle. Can be linked. Further, even if the connecting metal fitting is previously attached to the main member at the factory, the connection metal fitting falls down along the side surface of the main member, so that the metal fitting does not get in the way when the main member is carried from the factory to the construction site.

さらに、複数のベース金具を別々の主幹部材に設置し、接続金具をそのベース金具に跨って連結することで、従来のように互いに接合される横架部材の背丈を共通化する必要がなくなり、これにより各部材の寸法を強度と経済性を考慮して最適な状態とすることができる。また、分離したベース金具が接続金具で連結されることで、上下の主幹部材と梁とを強固に一体化できる。 Furthermore , by installing multiple base brackets on separate main members and connecting the connection brackets across the base brackets, there is no need to share the height of the horizontal members that are joined together as in the past, Thereby, the dimension of each member can be made into an optimal state in consideration of strength and economy. Moreover, the upper and lower trunk members and the beam can be firmly integrated by connecting the separated base metal fittings with the connection metal fittings.

請求項２記載の発明による連結金具は、接続金具の凹凸状の取付部をベース金具の被取付部に嵌合していること、及びこれらを貫通する連結ピンの相乗作用により、接続金具に加わる荷重や曲げ力に対して高い強度を発揮する。   According to a second aspect of the present invention, there is provided a connecting bracket which is applied to the connecting bracket by fitting the uneven mounting portion of the connecting bracket to the mounted portion of the base bracket and by the synergistic action of the connecting pin penetrating them.

The height of the horizontal member can be changed while the hole position of the hole is kept constant.

請求項４記載の発明のように、連結ピンを抜き差し自在とした場合には、ベース金具のみを工場で主幹部材に取付けておき、建築現場に搬入した後でベース金具に接続金具を簡単に連結できる。   When the connecting pin can be freely inserted and removed as in the invention described in claim 4, only the base metal fitting is attached to the main member at the factory, and the connecting metal fitting is simply connected to the base metal fitting after being brought into the construction site. it can.

請求項５記載の発明によれば、ベース金具に様々な大きさや形の接続金具を組み合わせることにより、横架部材の用途やサイズに合った多種類の連結金具を容易に製作できる。 According to the fifth aspect of the present invention, by combining the base metal fittings with various sizes and shapes, various types of connecting metal fittings suitable for the use and size of the horizontal member can be easily manufactured.

以下、本発明の実施の形態を図面に基づいて説明する。本発明による木造建築部材の連結金具は、図１に示すように、ベース金具１と、接続金具２と、連結ピン３とを備えてなり、接続金具２は連結ピン３を支点として左右に回動するようになっている。連結ピン３は、ベース金具１及び接続金具２に抜き差し自在にしてある。ベース金具１は、図４などに示すように、柱４等の主幹部材の側面にボルト５で固定され、接続金具２は梁６ａ等の横架部材の端部に上下方向に形成したスリット７に差し込み、ドリフトピン８ａ，８ｂにより横架部材に固定される。なお本連結金具の通常の使い方は、ベース金具１と接続金具２とに分離して、ベース金具１のみを工場で主幹部材に予め取付けておき、接続金具２は建築現場に搬入してから連結ピン３によりベース金具１に連結する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, a connecting member for a wooden building member according to the present invention comprises a base member 1, a connecting member 2, and a connecting pin 3. The connecting member 2 is rotated left and right with the connecting pin 3 as a fulcrum. It comes to move. The connecting pin 3 can be freely inserted into and removed from the base metal fitting 1 and the connection metal fitting 2. As shown in FIG. 4 and the like, the base metal fitting 1 is fixed to the side surface of the main member such as the pillar 4 with a bolt 5, and the connection metal fitting 2 is a slit 7 formed in the vertical direction at the end of a horizontal member such as the beam 6a. And is fixed to the horizontal member by the drift pins 8a and 8b. In addition, the normal usage of this connecting bracket is to separate the base bracket 1 and the connecting bracket 2 and attach only the base bracket 1 to the main member in advance at the factory, and connect the connecting bracket 2 after carrying it to the construction site. The pin 3 is connected to the base metal fitting 1.

ベース金具１は、金属の角棒を切削加工するなどして形成されるもので、前面部９を平面視半円状に面取りするとともに、前面部の上下方向に一定のピッチで凹凸状となった被取付部１０を形成してある。被取付部１０には、連結ピン３の挿通穴を上下方向に貫通して設けてある。さらに、被取付部１０の凹部には、前方より取付ボルトの挿通穴１１と、ボルトの頭部ないしナットが収まる座ぐり穴１２を設けてある。   The base metal fitting 1 is formed by cutting a metal square bar or the like. The base metal fitting 1 is chamfered in a semicircular shape when viewed from above and is uneven at a constant pitch in the vertical direction of the front surface portion. The attached portion 10 is formed. The attachment portion 10 is provided with an insertion hole for the connecting pin 3 penetrating in the vertical direction. Furthermore, the recessed part of the to-be-attached part 10 is provided with the insertion hole 11 of the attachment bolt from the front, and the counterbore hole 12 in which the head or nut of a bolt fits.

接続金具２は、厚さ数ミリの鉄板をレーザー加工機などで所定の形状に切断し、その板体１３のベース金具１側の端面に、所定の長さに切断した丸棒１４を間隔をおいて上下方向に並べて溶接し、凹凸状の取付部１５を形成してある。取付部１５には、連結ピン３の挿通穴を上下方向に貫通して設けてある。板体１３の上縁部と下縁部には、横架部材に貫通させたドリフトピン８ａの引っ掛け部１６を形成してあり、板体１３の先側の縁部には、固定用のドリフトピン８ｂの挿通穴１７を上下方向に間隔をおいて複数形成してある。この接続金具２は、取付部１５をベース金具１の被取付部１０に嵌合させ、上方より連結ピン３を差し込むことによりベース金具１に連結される。接続金具２の大きさや形は、横架部材のサイズ等に応じて適宜選択するもので、例えば図３に示すように、主幹部材としての梁２４の側面に登り梁１８を連結する場合には、登り梁１８に適した略平行四辺形状のものに取り替えることができるし、接続金具２の取付部１５をベース金具１の被取付部１０に高さを異ならせて嵌合することにより、ベース金具１の高さを同じにして、接続金具２の高さを変更することもできる。   The connection metal fitting 2 is formed by cutting an iron plate having a thickness of several millimeters into a predetermined shape with a laser processing machine or the like, and placing a round bar 14 cut into a predetermined length on the end surface of the plate body 13 on the base metal fitting 1 side. In this case, the concave and convex mounting portions 15 are formed by welding in the vertical direction. The attachment portion 15 is provided with an insertion hole for the connecting pin 3 penetrating in the vertical direction. A hook 16 of a drift pin 8a penetrating the horizontal member is formed on the upper edge and the lower edge of the plate 13, and a drift for fixing is provided on the front edge of the plate 13. A plurality of insertion holes 17 for the pins 8b are formed at intervals in the vertical direction. The connection fitting 2 is connected to the base fitting 1 by fitting the attachment portion 15 to the attachment portion 10 of the base fitting 1 and inserting the connecting pin 3 from above. The size and shape of the connecting fitting 2 are appropriately selected according to the size of the horizontal member, and for example, as shown in FIG. 3, when the climbing beam 18 is connected to the side surface of the beam 24 as the main member. It can be replaced with a substantially parallelogram shape suitable for the climbing beam 18, and the fitting portion 15 of the connection fitting 2 can be fitted to the attachment portion 10 of the base fitting 1 at different heights, so that the base It is also possible to change the height of the connection fitting 2 by making the height of the fitting 1 the same.

図４と図５は、本発明の連結金具の使用状態の一例で、柱４の左右の側面に梁６ａ，６ｂを上から見て斜めに連結し、柱４の後ろ側の側面には梁６ｃをまっすぐに連結しており、これらの連結箇所に本発明の連結金具をそれぞれ用いている。柱４の左右の側面には上下方向の四角い穴１９を形成してベース金具１を埋め込み、ボルト５とナット２０を用いてベース金具１を柱４に固定している。ベース金具１は、図５に示すように、ちょうど連結ピン３の中心の深さまで柱４に埋め込んである。ベース金具１は、いずれの連結金具も同じ大きさのものを用いているが、接続金具２は梁の背丈に応じて大きさの異なるものを用いている。柱４には、接続金具２をベース金具１に連結する際に、連結ピン３を上方から差し込めるように溝２１を形成してある。梁６ａ，６ｂには、幅方向の中央部に、接続金具２が嵌合するスリット７を形成してある。ベース金具１を連結ピン３の中心の深さまで柱４に埋め込むことで、梁をいかなる角度で柱４に連結する場合でも、スリット７の位置が梁の幅方向の中央に位置することになる。なお、ベース金具１の埋め込み深さを浅くしても梁を斜めに連結することは可能であるが、そうするとスリット７の位置が幅方向の中央から一方側にずれることになる。梁６ｃを柱４にまっすぐに連結する連結金具では、ベース金具１を柱４に埋め込まずに、柱４の側面に直接当接させてボルト５とナット２０で固定している。   FIGS. 4 and 5 show an example of the usage state of the connection fitting of the present invention. The beams 6a and 6b are connected obliquely to the left and right side surfaces of the column 4 when viewed from above, and the beam on the rear side surface of the column 4 6c is connected straightly, and the connecting metal fittings of the present invention are respectively used at these connecting portions. A square hole 19 in the vertical direction is formed on the left and right side surfaces of the pillar 4 to embed the base metal fitting 1, and the base metal fitting 1 is fixed to the pillar 4 using bolts 5 and nuts 20. As shown in FIG. 5, the base metal fitting 1 is embedded in the pillar 4 just to the depth of the center of the connecting pin 3. As for the base metal fitting 1, all of the connecting metal fittings have the same size, but the connecting metal fitting 2 has a different size according to the height of the beam. A groove 21 is formed in the column 4 so that the connecting pin 3 can be inserted from above when the connecting fitting 2 is connected to the base fitting 1. In the beams 6a and 6b, a slit 7 into which the connection fitting 2 is fitted is formed at the center in the width direction. By embedding the base metal fitting 1 in the column 4 to the depth of the center of the connecting pin 3, the slit 7 is positioned at the center in the width direction of the beam regardless of the angle at which the beam is connected to the column 4. Even if the embedding depth of the base metal fitting 1 is made shallow, it is possible to connect the beams obliquely, but in this case, the position of the slit 7 is shifted from the center in the width direction to one side. In the connecting metal fitting for connecting the beam 6c straight to the column 4, the base metal fitting 1 is not embedded in the column 4, but is directly brought into contact with the side surface of the column 4 and fixed with bolts 5 and nuts 20.

柱４に各梁６ａ，６ｂ，６ｃを連結する際の手順を述べると、柱４に予め取付けておいたベース金具１に接続金具２を連結ピン３で連結し、梁６ａ，６ｂ，６ｃは上側のドリフトピン８ａを予め打ち込んでおいて、接続金具２の上方より梁を下に下ろしながら接続金具２を梁のスリット７に差し込み、ドリフトピン８ａを接続金具の引っかけ部１６に引っ掛けて、最後に固定用のドリフトピン８ｂを梁６ａ，６ｂ，６ｃと接続金具２に貫通させる。   The procedure for connecting the beams 6a, 6b, and 6c to the column 4 will be described. The connecting metal 2 is connected to the base metal 1 that has been previously attached to the column 4 with the connecting pins 3, and the beams 6a, 6b, and 6c are The upper drift pin 8a is driven in advance, and the connecting fitting 2 is inserted into the slit 7 of the beam while lowering the beam from above the connecting fitting 2, and the drift pin 8a is hooked on the hooking portion 16 of the connecting fitting. The drift pin 8b for fixing is passed through the beams 6a, 6b, 6c and the connection fitting 2.

図６は、本発明の連結金具の使用状態の別の例であって、胴差し２２を挟んで１階部分の柱４ａと２階部分の柱４ｂを連結している箇所の側面に、梁６ｄ，６ｅを連結する場合を示している。胴差し２２は、梁６ｄ，６ｅよりも背丈の低い部材を用いており、胴差し２２の側面と１階部分の柱４ａの側面とにベース金具１をそれぞれ設置し、二つのベース金具１，１に跨がる形で接続金具２を連結ピン３により連結してある。１階部分の柱４ａと胴差し２２、２階部分の柱４ｂと胴差し２２とは、ホゾパイプ２３ａ，２３ｂによりそれぞれ連結してある。このような構造にすれば、ベース金具１は柱４ａと胴差し２２に予め取付けておくことができるし、各梁６ｄ，６ｅに埋め込まれる接続金具２はそれぞれ一体のものなので、梁６ｄ，６ｅに加わる曲げやねじりの力に対して高い強度で連結できる。また接続金具２が、分離したベース金具１，１を連結していることで、胴差し２２と、１階部分の柱４ａと、左右の梁６ｄ，６ｅとが一体化され、耐震性に優れた連結構造となる。   FIG. 6 is another example of the usage state of the connection fitting of the present invention, and the beam is formed on the side surface of the portion connecting the first floor portion pillar 4a and the second floor portion pillar 4b with the trunk 22 interposed therebetween. The case where 6d and 6e are connected is shown. The torso 22 uses a member having a lower height than the beams 6d and 6e, and the base metal fitting 1 is installed on the side surface of the torso 22 and the side surface of the pillar 4a on the first floor, respectively. The connecting fitting 2 is connected by the connecting pin 3 so as to straddle 1. The first floor portion pillar 4a and torso 22 and the second floor portion pillar 4b and torso 22 are connected by hozo pipes 23a and 23b, respectively. With such a structure, the base metal fitting 1 can be attached in advance to the pillar 4a and the trunk 22 and the connecting metal fittings 2 embedded in the beams 6d and 6e are integral with each other. It can be connected with high strength against bending and torsional forces applied to the wire. In addition, since the connecting metal fitting 2 connects the separated base metal fittings 1 and 1, the barrel 22, the first floor portion pillar 4 a, and the left and right beams 6 d and 6 e are integrated, and is excellent in earthquake resistance. It becomes a connected structure.

本発明の連結金具は、以上に述べた実施形態に限定されない。例えば、ベース金具の横幅を大きくし、取付ボルトの挿通孔と座ぐり穴をそのベース金具の両側部であって接続金具の両側に外れた位置に設けて、ベース金具に接続金具を連結した状態で主幹部材に取付けできるようにしてもよい。本連結金具の使用方法については、ベース金具の主幹部材への取付けを建築現場で行ってもよいし、ベース金具に接続金具を連結する作業を工場で行ってもよい。また、一体化した状態の連結金具を工場ないし建築現場で主幹部材に取付けてもよい。   The connecting metal fitting of the present invention is not limited to the embodiment described above. For example, when the width of the base bracket is increased and the insertion holes and counterbore holes for the mounting bolts are provided on both sides of the base bracket at positions off the both sides of the connection bracket, and the connection bracket is connected to the base bracket. It may be possible to attach to the main member. About the usage method of this connection metal fitting, the attachment to the main member of a base metal fitting may be performed in a construction site, and the operation | work which connects a connection metal fitting to a base metal fitting may be performed in a factory. Moreover, you may attach the connection metal fitting of the integrated state to a main member at a factory or a construction site.
