Description

【０００１】
【発明の属する技術分野】
本発明は、例えば柱に梁などの横架材を架け渡す際に、この柱と横架材とを連結する建築用木材の連結金具に関するものである。
【０００２】
【従来の技術及び発明が解決しようとする課題】
建築用木材の連結金具（継合金具）は、大別すると平断面コ字状あるいはＵ字状の二枚支持構造のものと、Ｔ字状の一枚支持構造のものとがあり、夫々の特徴をもって使い分けされており、連結する木材側のプレカットも夫々に合った加工がなされる。
【０００３】
この二枚支持構造のものは、例えば板材をコ字状あるいはＵ字状に折曲形成し、この折り返し部には、一方の木材に設けたボルト貫通孔に貫通される連結ボルトを挿通するボルト孔を設け、反対側の折曲遊離端側（二枚の支持板部）には、プレカットして形成した一方の木材の仕口部に連結（挿入して貫通ボルト止め）し得るように仕口連結部を設けた構成とし、一方の木材に連結固定した本金具の並設した二枚の支持板部を前記他方の木材の仕口部に係合して連結固定し、木材同志をこの金具によって連結する構成としている。
【０００４】
また、一枚支持構造のものは、Ｔ字状の基部のボルト孔を設けた取付板部を同様にして一方の木材に連結固定し、この取付板部から突出する一枚の支持板部を前記他方の木材の仕口部に係合して連結固定し、木材同志を同様に連結する構成としている。
【０００５】
このように例えば一方の木材である柱には数本の連結ボルトを貫通するボルト貫通孔を数ヵ所形成するが、このボルト貫通孔と連通合致される前記ボルト孔は、例えば意匠登録第８８６９０６号，意匠登録第１０６４３８０号などのように、二枚支持構造のコ字状あるいはＵ字状いずれの場合も曲げ巾のセンターに位置している。
【０００６】
ところが、一枚支持構造の場合は、例えば意匠登録第６４７８９１号，意匠登録第１０１９５３２号などのように取付板部と支持板部とのツーピース（別板材）を溶接で結合させるか、例えば意匠登録第９７９２２０号などのように左右対称の二枚の板材を背中合わせのように張り合わせて構成するかである。
【０００７】
しかしこのような一枚支持構造のものは、加工工程も多く、コスト高になる。
【０００８】
そのため、例えば意匠登録第１０１９７０５号，意匠登録第１０３３２２５号のように、一枚の板材から折曲して取付板部に対して支持板部を折曲突出形成する構成のものもあるが、前記柱に連結固定するための前記ボルト孔は、センター位置ではなく、支持板部に対して片側あるいは左右両側に折曲突出した取付板部に形成しなければならないため、支持板部の基端縁となる金具センター位置にボルト孔が形成できないこととなる。
【０００９】
このため、ボルト孔がセンターの支持板に対して片側にズレているから強度が低下するおそれがあると共に、この木材に対して二枚支持構造のものを採用する場合と、一枚支持構造を採用する場合とで柱を貫通させるボルト貫通孔の位置が異なるために、使用する金具によって異なる位置にボルト貫通孔を形成しなければならず、共通のプレカットとすることができない。
【００１０】
本発明は、このような問題点を見出しこれを解決したもので、別ピースを溶接で接合する構成ではなく、一枚の板材から一枚支持構造のものを折曲形成する構成でありながら、ボルト孔を二枚支持構造のものと同様に金具のセンター位置、即ち、支持板部の基端縁、更に言い換えれば、折曲形成した支持板部の折曲縁の長さ方向（長さ延長方向）に位置させるように構成して、木材に設ける連結ボルトのボルト貫通孔の位置をいずれの金具の場合も変える必要がなく、例えば仕口部を一枚の支持板部の場合も二枚の支持板部の場合も選択係合できるように加工すれば、ほとんど全く共通のプレカットで双方の金具が使用可能となる極めて画期的なセンター位置にボルト孔を設けた一枚支持構造の木材の連結金具を提供することを目的としている。
【００１１】
【課題を解決するための手段】
添付図面を参照して本発明の要旨を説明する。
【００１２】
一方の建築用木材１と、端部に仕口部２を設けた他方の建築用木材３とを直角若しくは傾斜状態に連結するための一枚の板材から成る木材の連結金具であって、一枚の板材に切り起こし折曲用の切込縁４を形成し、この切込縁４を介して取付板部５に対して支持板部６を略９０度折曲形成し、この取付板部５には前記一方の建築用木材１に当接し、この建築用木材１に設けたボルト貫通孔７に貫通される連結ボルト８を挿通するボルト孔９を設け、前記折曲形成した支持板部６には前記他方の建築用木材３に設けた仕口部２に連結する仕口連結部10を設け、前記支持板部６の折曲基部の折曲縁11の長さ方向が前記取付板部５の中央部に位置するように前記切込縁４の位置を設定すると共に、この切込縁４は、ボルト孔９の上下位置に臨むように形成して取付板部５が切り出されるように形成し、この折曲縁11の長さ方向に略合致する前記取付板部５の中央部に前記ボルト孔９を配設して、前記支持板部６と共にボルト孔９が取付板部５の中央部に位置するように構成したことを特徴とする木材の連結金具に係るものである。
【００１３】
【発明の実施の形態】
好適と考える本発明の実施の形態（発明をどのように実施するか）を、図面に基づいてその作用効果を示して簡単に説明する。
【００１４】
一枚の板材に切込縁４を形成する。例えば所定形状の板材を打ち抜き形成する際に切込部も形成して板材の所定位置に立ち起こし折曲のための前記切込縁４を形成する。
【００１５】
この切込縁４を利用して取付板部５に対して支持板部６を立ち起こし折曲形成する。
【００１６】
この際、前記切込縁４の設定によって本発明では、単に支持板部６の側方に取付板部５が折曲突出した形状とはならず、支持板部６の基端縁である折曲縁11の長さ方向（長さ延長方向）が取付板部５の中央部に位置する。
【００１７】
即ち、例えば予めこの取付板部５の中央部にボルト孔９を形成しておくことで、このボルト孔９は、支持板部６の折曲縁11の長さ方向に位置する。
【００１８】
従って、センター位置とする支持板部６の基端縁長さ方向、即ち、この支持板部６と共にセンター位置に前記ボルト孔９が配置された構成の一枚支持構造の木材の連結金具を、ツーピースの溶接構造とせずに一枚の板材からの折曲によって形成できることとなる。
【００１９】
従って、この折曲構造によって簡易なプレス加工などによって容易に製作でき、量産性に秀れ、コストアップにならないと共に、折曲構造であるから、一枚支持構造であってもセンター位置（支持板部６の基端縁長さ方向）に取付板部５に設けたボルト孔９を配置できるため、同様にセンター位置に設けた断面コ字状やＵ字状の二枚の支持板部６が並設した二枚支持構造の木材の連結金具を用いる場合も、本金具の一枚支持構造を用いる場合も、一方の木材１（柱）の所定位置にボルト貫通孔７を設けておけば双方とも使用でき、共通のプレカットで良いこととなる。
【００２０】
即ち、例えば他方の木材３（横架材）の仕口部２として二枚並設の支持板部６でも一枚の支持板部６でも選択挿入係合し得るようにプレカットして仕口部２形成しておけば、柱１側のボルト貫通孔７はセンター位置に設けておけば良く、このプレカットによって必要に応じて二枚支持構造の木材の連結金具でも本発明の一枚支持構造の木材の連結金具でも適宜採用可能となる画期的な木材の連結金具となる。
【００２１】
【実施例】
本発明の具体的な実施例について図面に基づいて説明する。
【００２２】
本実施例は、一方の建築用木材１である柱１と、他方の建築用木材３である梁などの横架材３とを連結する連結金具として構成し、木材１，３には、本実施例の一枚支持構造の連結金具でも、図１１に示すような二枚支持構造の連結金具でも使用できるようにプレカットしている。
【００２３】
柱１には、連結ボルト８を挿通してナット８Ａ止めするボルト貫通孔７を複数センター位置に縦列形成し、また横架材３の先端部には、センター位置の一枚支持板部６も二枚並設の支持板部も挿入係合可能な仕口部２を形成し、貫通ピン12で連結固定するように構成している。
【００２４】
従って、本実施例では、図１１に示すような二枚支持構造と同様に前記ボルト貫通孔７と連通合致するボルト孔９をセンター位置に設けることで、二枚支持構造の場合と同一のプレカットで使用できるように構成している。
【００２５】
即ち、一枚の板材に切り起こし折曲用の切込縁４を形成し、この切込縁４を介して取付板部５に対して支持板部６を略９０度折曲形成するが、前記支持板部６の折曲基部の折曲縁11の長さ方向が前記取付板部５の中央部に位置するように前記切込縁４の位置を設定し、この折曲縁11の長さ方向に略合致する前記取付板部５の中央部に前記ボルト孔９を配設している。
【００２６】
具体的には、一枚の板材をプレス加工によって所定形状に切り込む際に、前記ボルト孔９及び前記貫通ピン12を貫通する係止孔13を打ち抜き形成すると共に所定位置に切込部を形成して前記切込縁４を形成する。
【００２７】
この切込縁４は、この切込縁４を用いて直角に支持板部６を立ち起こす折曲縁11がこの折曲縁11線上に各ボルト孔９が並ぶように設定する。
【００２８】
例えば、図１〜図４に示す第一実施例では、取付板部５の二ヵ所にボルト孔９を形成する実施例であるが、このボルト孔９の上下位置に臨むように切込部を形成し（端部においては片側には板縁があるためボルト孔９の片側に臨むように切込部を形成し）、取付板部５が切り出されるように形成すると共に、この切込部による切込縁４を用いてボルト孔９の並列方向を折曲縁11として立ち起こすことで、このボルト孔９を中央部に設けた取付板部５に対して支持板部６が立設形成されて、この折曲縁11の延長ライン上に前記ボルト孔９が並設していて、立ち起こした支持板部６の基端縁長さ方向にボルト孔９が位置し、支持板部６と共にボルト孔９がセンター位置に配置されることとなる。
【００２９】
従って、単に支持板部６の片側に取付板部５を折曲突出したのでは、必ず支持板部６の片側にズレた位置に取付板部５があり、この取付板部５に対するボルト孔９はセンター位置には配設できないが、本実施例では、例えば前述のように切込縁４の形状や位置の設定により、取付板部５に対して支持板部６を折曲するだけで、一枚支持構造の本金具を形成できると共に、取付板部５の中央部に対して支持板部６が折曲立設し、この取付板部５の中央部のボルト孔９はこのセンターに位置する支持板部６と同様にセンター位置に形成できることとなる。
【００３０】
従って、予め柱１に設けるボルト貫通孔７をセンター位置に必要数あるいは様々な金具を想定して多数形成しておけば、この厄介なプレカットをその都度柱１に形成しなくても、共通のプレカットで一枚支持構造，二枚支持構造に限らず、使用可能となる。
【００３１】
また、図５〜図７に示す第二実施例は、更に多数のボルト孔９を取付板部５の多数のセパレートした部分に夫々形成した場合で、図８〜図１０に示す第３実施例は切り出される取付板部５のセパレートした部分に二つのボルト孔９を形成した場合を示すものである。
【００３２】
尚、本発明は、本実施例に限られるものではなく、各構成要件の具体的構成は適宜設計し得るものである。
【００３３】
【発明の効果】
本発明は上述のように構成したから、別ピースを溶接で接合する構成ではなく、一枚の板材から一枚支持構造のものを折曲形成する構成でありながら、ボルト孔を二枚支持構造のものと同様に金具のセンター位置、即ち、支持板部の基端縁、更に言い換えれば、折曲形成した支持板部の折曲縁の長さ方向（長さ延長方向）に位置させるように構成して、木材に設ける連結ボルトのボルト貫通孔の位置をいずれの金具の場合も変える必要がなく、例えば仕口部を一枚の支持板部の場合も二枚の支持板部の場合も選択係合できるように加工すれば、ほとんど全く共通のプレカットで双方の金具が使用可能となる極めて画期的なセンター位置にボルト孔を設けた一枚支持構造の木材の連結金具となる。

BACKGROUND OF THE INVENTION
The present invention relates to a construction lumber connecting bracket for connecting a pillar and a horizontal member, for example, when a horizontal member such as a beam is bridged over the pillar.
[0002]
[Prior art and problems to be solved by the invention]
Broadly speaking, there are two types of construction lumber connecting brackets (joint fittings): one with a U-shaped flat support or two with a T-shaped support, and one with a T-shaped support. It is used properly with its characteristics, and the precuts on the wood side to be connected are processed according to each.
[0003]
In this two-sheet support structure, for example, a plate material is bent into a U-shape or a U-shape, and a bolt through which a connection bolt that passes through a bolt through-hole provided in one wood is inserted into the folded portion. A hole is provided, and the opposite bent free end side (two support plate parts) is connected so that it can be connected (inserted and secured with a through bolt) to one of the lumber parts formed by pre-cutting. The structure is provided with a mouth connecting portion, and the two support plate portions of the metal fittings connected and fixed to one piece of wood are connected and fixed by engaging the joint portion of the other piece of wood. It is the structure connected with a metal fitting.
[0004]
In the case of a single-sheet support structure, the mounting plate portion provided with the bolt hole of the T-shaped base is connected and fixed to one piece of wood in the same manner, and the single supporting plate portion protruding from the mounting plate portion is provided. It is configured to engage and fix the other lumber joint, and to connect the woods in the same manner.
[0005]
In this way, for example, several pillar through holes that penetrate several connecting bolts are formed in a pillar that is one wood, and the bolt hole that communicates with the bolt through hole is, for example, Design Registration No. 886906. As in Design Registration No. 1064380, the U-shaped or U-shaped two-sheet support structure is located at the center of the bending width.
[0006]
However, in the case of a single-sheet support structure, for example, as in Design Registration No. 647891, Design Registration No. 1019532 or the like, two pieces (separate plate materials) of the mounting plate portion and the support plate portion are joined together by welding, for example, design registration As shown in No. 979220 or the like, two symmetrical plates are laminated together like back to back.
[0007]
However, such a single-sheet support structure has many processing steps and is expensive.
[0008]
For this reason, for example, there is a configuration in which the support plate portion is bent and formed with respect to the mounting plate portion by bending from a single plate material, such as design registration No. 1019705 and design registration No. 1033225. The bolt hole for connecting and fixing to the pillar must be formed not on the center position but on the mounting plate part that is bent and protruded on one side or both right and left sides of the support plate part. Thus, the bolt hole cannot be formed at the metal center position.
[0009]
For this reason, since the bolt hole is shifted to one side with respect to the support plate of the center, there is a possibility that the strength may be reduced, and when using a two-sheet support structure for this wood, Since the position of the bolt through-hole through which the column passes is different in the case where it is adopted, the bolt through-hole must be formed at a different position depending on the metal fitting to be used, and a common precut cannot be made.
[0010]
The present invention finds such a problem and solves this, and is not configured to weld another piece by welding, but is configured to bend one of the support structure from one plate material, As with the two- bolt support structure, the center position of the bracket, that is, the base end edge of the support plate, or in other words, the length direction (length extension) of the bent support plate portion It is not necessary to change the position of the bolt through-holes of the connecting bolts provided on the wood in any of the metal fittings, for example, in the case of a single support plate part. If it is processed so that it can be selectively engaged even in the case of the support plate part of the wood, it is a single piece support structure wood with a bolt hole at a very innovative center position that makes it possible to use both brackets with almost the same pre-cut The purpose is to provide connecting brackets .
[0011]
[Means for Solving the Problems]
The gist of the present invention will be described with reference to the accompanying drawings.
[0012]
A timber connection bracket made of a single plate material for connecting one building wood 1 and the other building wood 3 provided with a joint 2 at the end in a right angle or inclined state, A cut edge 4 for cutting and raising is formed on a sheet of plate material, and a support plate portion 6 is bent about 90 degrees with respect to the attachment plate portion 5 via the cut edge 4. 5 is provided with a bolt hole 9 which is in contact with the one building wood 1 and through which a connecting bolt 8 is inserted through a bolt through hole 7 provided in the building wood 1, and the bent support plate portion. 6 is provided with a joint connecting part 10 connected to the joint part 2 provided on the other building wood 3, and the length direction of the bent edge 11 of the bent base part of the support plate part 6 is the mounting plate. The position of the cutting edge 4 is set so as to be located at the center of the part 5, and the cutting edge 4 faces the vertical position of the bolt hole 9. The mounting plate portion 5 is formed so as to be cut out, and the bolt hole 9 is disposed in the central portion of the mounting plate portion 5 that substantially matches the length direction of the bent edge 11, and the support plate The present invention relates to a timber connection fitting characterized in that the bolt hole 9 is located in the central portion of the mounting plate portion 5 together with the portion 6 .
[0013]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention (how to carry out the invention) considered to be suitable will be briefly described with reference to the drawings, showing its effects.
[0014]
The incision edge 4 is formed on one plate. For example, when a plate material having a predetermined shape is punched and formed, a cut portion is also formed and raised at a predetermined position of the plate material to form the cut edge 4 for bending.
[0015]
The support plate portion 6 is raised with respect to the mounting plate portion 5 by using the cut edge 4 to be bent.
[0016]
At this time, according to the present invention, the setting of the cutting edge 4 does not have a shape in which the mounting plate part 5 bends and protrudes to the side of the support plate part 6, but the folding which is the base edge of the support plate part 6. The length direction (length extension direction) of the curved edge 11 is located at the center of the mounting plate portion 5.
[0017]
That is, for example, by forming a bolt hole 9 in the central portion of the mounting plate portion 5 in advance, the bolt hole 9 is positioned in the length direction of the bent edge 11 of the support plate portion 6.
[0018]
Therefore, the base metal edge length direction of the support plate portion 6 as the center position, i.e., the one-piece support structure wood connecting bracket in which the bolt hole 9 is arranged at the center position together with the support plate portion 6, It can be formed by bending from a single plate material without a two-piece welded structure.
[0019]
Therefore, this bent structure can be easily manufactured by simple press working, etc., is excellent in mass productivity, does not increase the cost, and has a bent structure. Since the bolt hole 9 provided in the mounting plate portion 5 can be arranged in the base edge length direction of the portion 6, the two support plate portions 6 having a U-shaped cross section or U shape provided at the center position are similarly provided. Whether using a two-piece support structure of wood jointed in parallel or using a single-piece support structure of the main part, both can be provided by providing bolt through-holes 7 at predetermined positions on one piece of wood 1 (post). Both can be used and a common precut is sufficient.
[0020]
That is, for example, the joint portion 2 of the other wood 3 (horizontal material) is pre-cut so that it can be selectively inserted and engaged with either the two support plate portions 6 or the single support plate portion 6. If it is formed, the bolt through hole 7 on the pillar 1 side may be provided at the center position. If necessary, this pre-cut can also be used for a single metal support structure of the present invention even with a double metal support structure. This is an epoch-making wood connection fitting that can be appropriately adopted even with a wood connection fitting.
[0021]
【Example】
Specific embodiments of the present invention will be described with reference to the drawings.
[0022]
The present embodiment is configured as a connecting metal fitting for connecting the pillar 1 which is one building wood 1 and the horizontal member 3 such as a beam which is the other building wood 3. The connecting bracket having the single-sheet supporting structure of the embodiment or the connecting bracket having the two-sheet supporting structure as shown in FIG. 11 is pre-cut so that it can be used.
[0023]
The pillar 1 is formed with a plurality of bolt through holes 7 through which the connecting bolts 8 are inserted and fixed to the nuts 8 </ b> A in a plurality of center positions, and a single support plate 6 at the center position is also provided at the tip of the horizontal member 3. The two support plates are also formed so as to form the joint portion 2 that can be inserted and engaged, and are connected and fixed by the through pin 12.
[0024]
Therefore, in the present embodiment, the same pre-cut as in the case of the two-sheet support structure is provided by providing the bolt hole 9 in communication with the bolt through hole 7 at the center position as in the two-sheet support structure as shown in FIG. It is configured so that it can be used.
[0025]
That is, a cut edge 4 for cutting and raising is formed on a single plate material, and the support plate portion 6 is bent about 90 degrees with respect to the mounting plate portion 5 through the cut edge 4. The position of the cut edge 4 is set so that the length direction of the bent edge 11 of the bent base portion of the support plate portion 6 is located at the center of the mounting plate portion 5, and the length of the bent edge 11 is set. The bolt hole 9 is disposed at the center of the mounting plate 5 that substantially matches the vertical direction.
[0026]
Specifically, when a single plate material is cut into a predetermined shape by pressing, the locking hole 13 penetrating the bolt hole 9 and the through pin 12 is formed by punching and a notch is formed at a predetermined position. Thus, the cut edge 4 is formed.
[0027]
The cut edge 4 is set so that the bent edge 11 that raises the support plate portion 6 at a right angle by using the cut edge 4 is aligned with the bolt holes 9 on the bent edge 11 line.
[0028]
For example, in the first embodiment shown in FIGS. 1 to 4, the bolt holes 9 are formed in two places of the mounting plate portion 5, but the notches are formed so as to face the vertical positions of the bolt holes 9. (Because there is a plate edge on one side at the end, a notch is formed so as to face one side of the bolt hole 9), and the mounting plate 5 is formed so as to be cut out. By raising the parallel direction of the bolt holes 9 as the bent edges 11 using the cut edges 4, the support plate portion 6 is formed upright with respect to the mounting plate portion 5 provided with the bolt holes 9 in the center portion. The bolt holes 9 are juxtaposed on the extension line of the bent edge 11, and the bolt holes 9 are located in the length direction of the base edge of the support plate portion 6 raised up together with the support plate portion 6. The bolt hole 9 is disposed at the center position.
[0029]
Therefore, if the mounting plate portion 5 is simply bent and protruded on one side of the support plate portion 6, the mounting plate portion 5 is always located at a position shifted to one side of the support plate portion 6, and a bolt hole 9 for the mounting plate portion 5 is provided. However, in the present embodiment, for example, as described above, by simply setting the shape and position of the cutting edge 4, the support plate portion 6 is simply bent with respect to the mounting plate portion 5, A single metal support structure can be formed, and the support plate portion 6 is bent with respect to the center portion of the attachment plate portion 5, and the bolt hole 9 in the center portion of the attachment plate portion 5 is positioned at this center. It can form in a center position similarly to the support plate part 6 to perform.
[0030]
Therefore, if a large number of bolt through holes 7 provided in the pillar 1 are formed at the center position assuming a necessary number or various metal fittings, it is possible to share a common pre-cut without having to form the troublesome precut in the pillar 1 each time. The pre-cut is not limited to the one-sheet support structure or the two-sheet support structure, and can be used.
[0031]
Further, the second embodiment shown in FIGS. 5 to 7 is a case where a large number of bolt holes 9 are formed in a large number of separated portions of the mounting plate portion 5, respectively, and the third embodiment shown in FIGS. Shows a case where two bolt holes 9 are formed in a separated portion of the mounting plate portion 5 to be cut out.
[0032]
Note that the present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate.
[0033]
【The invention's effect】
Since the present invention is configured as described above, it is not a configuration in which separate pieces are joined by welding, but a configuration in which a single-sheet support structure is bent from a single plate material, but two bolt holes are supported. The center position of the metal fitting, that is, the base end edge of the support plate portion, in other words, the bending direction of the bent support plate portion in the length direction (length extension direction). It is not necessary to change the position of the bolt through hole of the connecting bolt provided in the wood in any case, for example, in the case of one support plate part or two support plate parts. If it is processed so that it can be selectively engaged, it will be a wood support metal fitting with a single support structure in which a bolt hole is provided at a very innovative center position where both metal fittings can be used with almost the same pre-cut.
