Description

本発明は、例えば、木製の柱などの建築用木材と、木製の梁などの連結用木材とを接合する木材接合金具に関するものである。   The present invention relates to a wood joining metal fitting for joining a building wood such as a wooden pillar and a connecting wood such as a wooden beam.

従来の木材の接合構造としては、例えば特開2000−104343号(特許文献1)にあるように、断面コ字型若しくはU字型の接合金具を用いる構造がある。   As a conventional wood joining structure, for example, as disclosed in Japanese Patent Application Laid-Open No. 2000-104343 (Patent Document 1), there is a structure using a U-shaped joining metal fitting having a U-shaped cross section.

具体的には、縦材(柱材)などの建築用木材の周面部に当接固定する取付板部と、この取付板部から突出して横材(梁材や桁材)などの連結用木材の端部の仕口部のスリットに継合連結される左右一対の継合板部とから成る断面コ字型若しくはU字型の接合金具を用いる。   Specifically, a mounting plate that abuts and fixes to the peripheral surface of a building wood such as a vertical member (column), and a connecting wood such as a cross member (beam or girder) that protrudes from the mounting plate. A U-shaped joining bracket having a U-shaped cross section composed of a pair of right and left joint plate parts joined and connected to the slit of the end portion of the joint is used.

この接合金具は、取付板部には、前記建築用木材の側面より貫通突出する取付ボルトを貫通するボルト孔が上下方向に複数並設状態に設けられ、この接合金具の左右の継合板部には夫々、前記連結用木材の端部にして仕口部に形成された係止孔に挿通固定する係止体(ドリフトピン)を挿通するための係合孔や、前記仕口部の係止孔に挿通固定した最も上側位置の係止体を掛け止め状態に連結するためのあご掛け凹部が設けられている。   In this joining bracket, the mounting plate portion is provided with a plurality of bolt holes penetrating the mounting bolts penetrating and projecting from the side surface of the building wood in the vertical direction. Respectively, an engagement hole for inserting a locking body (drift pin) that is inserted into and fixed to an engagement hole formed in the joint portion as an end portion of the connecting wood, and the engagement of the joint portion A jaw hooking concave portion is provided for connecting the uppermost position locking body inserted and fixed in the hole into a hooked state.

そして、例えば、先ず建築用木材の対向側面間に貫通状態に設けたボルト孔に貫通した取付ボルトにより、この建築用木材の側面(周面)に接合金具の取付板部を当接固定する。   For example, first, the mounting plate portion of the joint metal fitting is abutted and fixed to the side surface (circumferential surface) of the building wood with a mounting bolt penetrating through a bolt hole provided between the opposing side surfaces of the building wood.

次いで、この接合金具の継合板部を連結用木材の仕口部のスリット内に挿入配設しつつ、この仕口部の最も上側の係止孔に予め挿通係止しておいた係止体を前記あご掛け凹部に上方から載置支承させて掛け止め状態に連結する。   Next, a locking body that is inserted and locked in advance in the uppermost locking hole of the joint portion while the joint plate portion of the joint metal fitting is inserted and disposed in the slit of the joint portion of the connecting wood. Is placed and supported on the jaw hanging recess from above and connected to the latched state.

その後、この仕口部の残余の挿通孔と、前記継合板部の係合孔とを連通させて係止体を打ち込み固定して、この継合板部を前記連結用木材の仕口部に接合連結し、これにより建築用木材と連結用木材とを直角若しくは傾斜状態に接合する構造である。   Thereafter, the remaining insertion hole of the joint portion and the engagement hole of the joint plate portion are communicated to fix the locking body, and the joint plate portion is joined to the joint portion of the connecting wood. In this structure, the building wood and the connecting wood are joined at a right angle or in an inclined state.

また、従来から、例えば特開2004−108030号(特許文献2)にあるような、断面T字状で継合板部が一枚構造のものも実施されている。   Conventionally, for example, as disclosed in Japanese Patent Application Laid-Open No. 2004-108030 (Patent Document 2), one having a T-shaped cross section and a single joining plate portion has been implemented.

この種の木材接合金具にコストダウンの要望がある。   There is a demand for cost reduction in this kind of wood joint metal fittings.

コストダウンに最も効果的なのは、金具の板厚を薄くして材料の使用量を減らすことである。   The most effective way to reduce costs is to reduce the amount of material used by reducing the thickness of the bracket.

しかし、金具を薄厚化してしまうと強度不足が懸念される上、前記左右一対の継合板部はもともと仕口部のスリット幅に対応させた板厚に設計されているから、薄厚化した継合板部では仕口部のスリット内で連結用木材の長さ方向と直交する方向にガタついて十分な接合精度が確保できなくなってしまう。尚、このガタつきの問題は、継合板部の薄厚化に合わせてスリット幅も狭くすることで解決可能であるが、この種の接合金具に使用する木材の仕口形状も規格化が進んでいるため、スリット幅の変更は容易にはできないという現状である。   However, there is a concern about insufficient strength if the metal fitting is thinned, and the pair of left and right joint plates are originally designed to have a thickness corresponding to the slit width of the joint, so the thin joint plate In such a case, the joint rattles in the direction perpendicular to the length direction of the connecting wood within the slit of the joint, and sufficient joining accuracy cannot be ensured. This rattling problem can be solved by narrowing the slit width in accordance with the thinning of the joint plate, but the shape of the lumber used for this type of joint fitting is also being standardized. Therefore, the current situation is that the slit width cannot be easily changed.

本発明は、上記コストダウンの要望に応えるために開発されたもので、金具を薄厚化してコストダウン・軽量化を図る構成でありながら強度が向上し、且つ継合板部が木材の仕口部のスリットに対してガタつきにくく従来品と同等の接合精度を確保できる木材接合金具を提供するものである。   The present invention was developed to meet the above-mentioned demand for cost reduction, and the strength is improved while the structure is designed to reduce the cost by reducing the thickness of the metal fittings. It is intended to provide a wood joining metal fitting that is less likely to rattle against the slits and can ensure the same joining accuracy as a conventional product.

添付図面を参照して本発明の要旨を説明する。   The gist of the present invention will be described with reference to the accompanying drawings.

建築用木材1と、端部に仕口部3を設けた連結用木材2とを直角若しくは傾斜状態に接合する木材接合金具Aであって、前記建築用木材1の周面部に当接状態に取付けする取付板部5と、前記連結用木材2の仕口部3のスリット4に挿入して継合連結する継合板部6とから成り、一枚の板材を折曲することで前記取付板部5から前記継合板部6が折曲突出する構成とした木材接合金具Aにおいて、前記継合板部6の板厚寸法を、前記仕口部3のスリット4幅より薄厚に設定し、この継合板部6に、この継合板部6の一側板面を凹設することで他側板面を凸設させた凸条7を一体成形すると共に、この凸条7の前記継合板部6の他側板面に対する突出度を、この凸条7を含めた前記継合板部6の板厚寸法が、前記仕口部3のスリット4幅に合致する板厚となる突出度に設定して、この凸条7がスリット4の内面に接する構成とし、この凸条7は、前記継合板部6の前記取付板部5に対する折曲突出方向に連続する横長凸条7Aと、継合板部6の上下方向に連続する縦長凸条7Bとが連設する形状に形成すると共に、この横長凸条7Aと縦長凸条7Bとは、前記継合板部6の周縁部を避けた中央側に形成して、この継合板部6の周縁部の板厚寸法が、前記仕口部3のスリット4幅より薄厚となるように構成したことを特徴とする木材接合金具に係るものである。

好適と考える本発明の実施形態を、図面に基づいて本発明の作用を示して簡単に説明する。   An embodiment of the present invention which is considered to be suitable will be briefly described with reference to the drawings showing the operation of the present invention.

本発明の接合金具Aは、継合板部6の板厚寸法を、前記仕口部3のスリット4幅より薄厚に設定する。   In the joining metal fitting A of the present invention, the thickness of the joint plate portion 6 is set to be thinner than the slit 4 width of the joint portion 3.

即ち、継合板部6を薄厚化してコストダウンでき、また、薄厚化により軽量化できて取扱性が向上する。   That is, the joint plate portion 6 can be reduced in thickness to reduce the cost, and the thickness can be reduced in weight to improve handling.

また、この薄厚化した継合板部6は、従来品に比して強度不足の懸念があるが、本発明は、この継合板部6に、この継合板部6の一側板面を凹設することで他側板面を凸設させた凸条7を一体成形する。 Moreover, although this thinned joint plate part 6 has a possibility that the strength is insufficient as compared with the conventional product, the present invention has a concave one side plate surface of the joint plate part 6 in the joint plate part 6. Thus, the ridge 7 with the other side plate surface protruding is integrally formed.

すると、この一体成形による凸条7によって継合板部6が補強されるので、薄厚化によって失われた継合板部6の強度が補われて強度不足の懸念がない。 Then, since thus joint plate portions 6 in ridges 7 by the integral molding is reinforced, there is no fear of strength supplemented with insufficient strength of the joint plate portion 6 lost by thinning.

また、本発明の凸条7は、前記継合板部6の他側板面に対する突出度を、この凸条7を含めた前記継合板部6の板厚寸法が、前記仕口部3のスリット4幅に合致する板厚となる突出度に設定する。 Further, the protrusion 7 of the present invention has a degree of protrusion with respect to the other side plate surface of the joint plate portion 6, and the thickness of the joint plate portion 6 including the protrusion 7 is the slit 4 of the joint portion 3. setting the projecting degree of the thickness match the width.

そのため、継合板部6自体は薄厚化しているものの、この薄厚化した継合板部6を、連結用木材2の仕口部3のスリット4に挿入した際には、継合板部6とスリット4とに生じる隙間を凸条7が埋める役割を果たすので、継合板部6がスリット4内で連結用木材2の長さ方向と直交する方向にガタつくことはない。 Therefore, although the joining plate portion 6 itself is thinned, when the thinned joining plate portion 6 is inserted into the slit 4 of the joint portion 3 of the connecting wood 2, the joining plate portion 6 and the slit 4 are provided. Since the ridges 7 fill the gaps that occur in the gap, the joining plate portion 6 does not rattle in the slit 4 in the direction perpendicular to the length direction of the connecting wood 2.

従って、継合板部6を薄厚化してコストダウンを図る構成でありながら強度が向上し、且つ仕口部3への専用加工も不要で継合板部6が既存の連結用木材2の仕口部3のスリット4に対してガタつきにくく従来品と同等の接合精度を確保できる極めて実用性に優れた木材接合金具Aとなる。   Accordingly, the thickness is improved by reducing the thickness of the joint plate portion 6 while reducing the cost, and the joint plate portion 6 is not required to be specially processed to the joint portion 3, and the joint portion 6 of the existing connecting wood 2 is used. Thus, the wood joining metal fitting A can be secured with the same accuracy as that of the conventional product.

また、継合板部6に設ける凸条7は、例えば金属プレス加工により容易に形成可能である。 Further, the ridges 7 provided on the joint plate portion 6 can be easily formed by, for example, metal pressing.

本発明の具体的な実施例について図1〜図5に基づいて説明する。 For the specific embodiment of the present invention will be described with reference to FIGS.

本実施例の木材接合金具Aは、建築用木材1の周面部に取付けする取付板部5と、端部に仕口部3を設けた連結用木材2の仕口部3に連結する継合板部6とを備えている。   The wood joining bracket A of this embodiment is a joint plate that is connected to a mounting plate portion 5 that is attached to the peripheral surface portion of the building wood 1 and a joint portion 3 of the connecting wood 2 that is provided with a joint portion 3 at the end. Part 6.

具体的には、図1に示すように一枚の金属製(ステンレスなど)方形板材を二つ折り形状(断面コ字状)に折り返し形成して、折り返し部を前記取付板部5とし、この取付板部5の反対側に位置する左右の遊離板部を、取付板部5から90度折曲突出する前記継合板部6としている。即ち、本実施例は、前記特許文献1と同様の二枚の継合板部6を具備する二枚支持タイプ(断面略コ字型)の木材接合金具A1に適用している。   Specifically, as shown in FIG. 1, a single metal (stainless steel, etc.) rectangular plate material is folded back into a double fold shape (cross-sectional U shape), and the folded portion is used as the mounting plate portion 5, and this mounting is performed. The left and right free plate portions located on the opposite side of the plate portion 5 are the joint plate portions 6 that protrude 90 degrees from the mounting plate portion 5. In other words, the present embodiment is applied to a two-sheet support type (substantially U-shaped cross-section) wood joint metal fitting A1 including two joint plate portions 6 similar to those in Patent Document 1.

また、取付板部5は、その断面形状を、前記建築用木材1に対して前記連結用木材2が引っ張られる方向に負荷を受けて継合板部6が引っ張られた際に、コ字状の断面折り返し形状から変形すると想定した形状であって且つコ字状の折り返し形状のように直角の折曲部分を有しない折り返し形状に形成した構成としている。   Further, the mounting plate portion 5 has a U-shaped cross section when the joint plate portion 6 is pulled by receiving a load in a direction in which the connecting wood 2 is pulled with respect to the building wood 1. The shape is assumed to be deformed from the folded shape of the cross section, and is formed in a folded shape that does not have a right-angled bent portion like a U-shaped folded shape.

具体的には、この取付板部5の形状は、図2,図4に示すように折り縁を有しない湾曲状に折曲した断面略U字状に形成している。これにより、たとえ建築用木材1に対して連結用木材2が引っ張られる方向に負荷がかかったとしても、取付板部5はこの断面略U字形状から更に変形することは起こりにくいため、秀れた耐変形強度を発揮して秀れた連結力を実現できる構成としている。   Specifically, as shown in FIGS. 2 and 4, the shape of the mounting plate portion 5 is formed in a substantially U-shaped cross section that is bent into a curved shape having no folding edge. Thereby, even if a load is applied in the direction in which the connecting wood 2 is pulled with respect to the building wood 1, the mounting plate portion 5 is unlikely to be further deformed from the substantially U-shaped cross section. It has a configuration that can achieve excellent connection strength by exhibiting excellent deformation resistance.

また、この取付板部5には、建築用木材1の周面部より、この周面部に設けたボルト孔11を介して貫通突出させた取付ボルト9を挿通するためのボルト挿通孔10を上下方向に所定間隔をおいて複数箇所(本実施例では二箇所)に設けている。   Further, the mounting plate portion 5 is provided with a bolt insertion hole 10 for inserting a mounting bolt 9 penetrating and projecting from a peripheral surface portion of the building wood 1 through a bolt hole 11 provided in the peripheral surface portion. Are provided at a plurality of locations (two locations in the present embodiment) at predetermined intervals.

また、前記継合板部6は、その取付板部5に対する突出先端側の上部に、ドリフトピン12を掛止し得る略U状の掛止凹部13を形成し、同突出先端側の下部にドリフトピン12を係止し得る係合孔14を形成している。   Further, the joining plate portion 6 is formed with a substantially U-shaped latching recess 13 capable of latching the drift pin 12 in the upper portion on the projecting tip side with respect to the mounting plate portion 5, and drifts in the lower portion on the projecting tip side. An engagement hole 14 that can lock the pin 12 is formed.

また、本実施例は、前記継合板部6の板厚寸法を、前記仕口部3のスリット4幅より薄厚に設定している。   In this embodiment, the thickness of the joint plate 6 is set to be thinner than the width of the slit 4 of the joint 3.

具体的には、接合金具A1を構成する板材の板厚寸法を、従来品の板厚寸法に比して1mm程度薄くすることで前記取付板部5とともに継合板部6を薄厚化し、材料使用量の減量によるコストダウンを図ると共に、軽量化を図っている。   Specifically, by reducing the thickness of the plate constituting the joint metal fitting A1 by about 1 mm as compared with the plate thickness of the conventional product, the connecting plate portion 6 and the connecting plate portion 6 are made thinner, and the material is used. In addition to reducing costs by reducing the amount, the weight is reduced.

また、本実施例は、この継合板部6に、この継合板部6の一側板面を凹設することで他側板面を凸設させた凸条7(リブ)を一体成形すると共に、この凸条7の前記継合板部6の他側板面に対する突出度を、この凸条7を含めた前記継合板部6の板厚寸法が、前記仕口部3のスリット4幅に合致する若しくはスリット4幅よりやや薄い板厚となる突出度に設定している。   Further, in the present embodiment, the joint plate portion 6 is integrally formed with a ridge 7 (rib) in which the other side plate surface is projected by recessing one side plate surface of the joint plate portion 6. The degree of protrusion of the ridge 7 with respect to the other side plate surface of the joint plate portion 6 is such that the plate thickness dimension of the joint plate portion 6 including the ridge 7 matches the width of the slit 4 of the joint portion 3 or the slit. The projecting degree is set to a thickness slightly thinner than 4 widths.

具体的には、図2に示すように、プレス加工により各継合板部6の対向内側板面を外方へ凹設することで、この凹設部15と同形状の凸条7を継合板部6を薄くした厚さ分だけ継合板部6の外側板面に凸設させた構成として、この凸条7を含めた継合板部6の板厚寸法がスリット4幅に略合致する板厚となるようにしている。尚、各継合板部6の外側板面を内方へ凹設することで、継合板部6の内側板面に凸条7を突設させる構成としても良い。   Specifically, as shown in FIG. 2, by projecting the opposing inner plate surface of each joint plate portion 6 outward by pressing, the convex strip 7 having the same shape as the concave portion 15 is joined to the joint plate. As a configuration in which the thickness of the portion 6 is reduced by the thickness of the outer plate surface of the joint plate portion 6, the thickness of the joint plate portion 6 including the ridges 7 substantially matches the width of the slit 4. It is trying to become. In addition, it is good also as a structure which makes the protrusion 7 project on the inner side plate surface of the joint plate part 6 by making the outer side plate surface of each joint plate part 6 inwardly provided.

また、この凸条7は、継合板部6に、この継合板部6の前記取付板部5に対する折曲突出方向に連続する横長凸条7Aと、継合板部6の上下方向に連続する縦長凸条7Bとが連設する形状に形成している。   Further, the protruding strip 7 is formed on the joining plate portion 6, a horizontally long protruding strip 7 </ b> A that is continuous in the bending projecting direction of the joining plate portion 6 with respect to the mounting plate portion 5, and a vertically long continuous shape of the joining plate portion 6. It is formed in a shape in which the ridges 7B are continuously provided.

更に詳しくは、各継合板部6の上下方向の中ほど位置に、この継合板部6の基端部(前記取付板部5側)から突出先端部にかけて水平方向に連続する直線状の前記横長凸条7Aを形成し、この横長凸条7Aを直交するようにして継合板部6の基端部付近と継合板部6の突出方向の中間部付近とに、この継合板部6の下部から上部にかけて鉛直方向に連続する直線状の縦長凸条7Bを設けた構成としている。   More specifically, in the middle of the vertical direction of each joint plate portion 6, the linear horizontally long continuous in the horizontal direction from the base end portion (the mounting plate portion 5 side) of this joint plate portion 6 to the projecting distal end portion. From the lower part of this joining plate part 6, it forms the protruding item | line 7A, and this horizontal elongate protruding item | line 7A is orthogonally crossed in the vicinity of the base end part of the joining board part 6, and the intermediate part vicinity of the protrusion direction of the joining board part 6. It is set as the structure which provided the linear elongate protruding item | line 7B which continues in a perpendicular direction over the upper part.

従って、このように凸条7を横長凸条7Aと縦長凸条7Bとから成る形状として継合板部6の広範囲に設けたことにより、この凸条7が連結用木材2の仕口部3のスリット4の内面の広範囲に接触して良好なガタつき防止効果を発揮する構成としている。   Therefore, by providing the ridges 7 in a wide range of the joining plate portion 6 as a shape composed of the horizontally long ridges 7A and the vertically long ridges 7B in this way, the ridges 7 are formed in the joint portion 3 of the connecting wood 2. It is configured to exhibit a good anti-rattle effect by contacting a wide range of the inner surface of the slit 4.

また、この広範囲の凸条7によって継合板部6が補強されて強度が向上する構成としている。出願人の試作実験によると、凸条7若しくは後述の突起8(構成例1〜3)を形成することによって従来品の継合板部に比べて若干強度が低いか若しくは同等程度の強度が得られることが確認されている。 Moreover, it is set as the structure which the joint plate part 6 is reinforced by this wide ridge 7 and an intensity | strength improves. According to the applicant's prototype experiment, forming the ridges 7 or the projections 8 ( configuration examples 1 to 3 ) to be described later has a slightly lower strength or a comparable strength compared to the conventional joining plate portion. It has been confirmed.

次に、本実施例で使用する建築用木材1と、連結用木材2とを説明する。   Next, the building wood 1 and the connecting wood 2 used in this embodiment will be described.
