Description

本発明は、角材や丸材など長手の木質部材に固有の質感を確保しつつ、これと直交する方向の剪断耐力を増すようにした、木質部材の補強構造に関する。   The present invention relates to a reinforcing structure for a wooden member that secures a texture specific to a long wooden member such as a square member or a round member, while increasing the shear strength in a direction orthogonal to the longitudinal wooden member.

木質軸組構造の構造物躯体を構成する木質の横架材や縦材にあっては、材質によって多少異なるものの、両端固定された木質部材の長さ方向に直交して剪断荷重が作用すると、その中央部に応力が集中して曲げ力が作用し、木目が開く方向に変形し、ついには剪断破壊されてしまう恐れがある。   In the case of wooden horizontal members and vertical members that make up the structural frame of a wooden frame structure, although slightly different depending on the material, when a shear load acts perpendicular to the length direction of the wooden member fixed at both ends, There is a risk that stress concentrates on the central part and bending force acts, deforms in the direction in which the wood grain opens, and eventually breaks in shear.

剪断耐力を増すためには部材断面を大きく取れば良いが、資材単価が高くなり、同一構造物容積の場合には、部材断面が増す分、間取が減少する欠点も生ずる。また、部材のスパンを短くすればよいが、この場合には他の部材との取合い箇所が多くなり、構造が複雑化する。   In order to increase the shear strength, it is sufficient to increase the cross section of the member. However, the unit price of the material is increased, and in the case of the same structure volume, there is a disadvantage that the layout is reduced as the cross section of the member is increased. Moreover, the span of the member may be shortened, but in this case, the number of places where the member is engaged with each other increases and the structure becomes complicated.

そこで補強構造として、短冊金物、その他接合金物などの鋼板などの平板状の補強金物を外面に添付して木質部材を補強する構造がある。しかし、これら補強金物は、一般に木質部材の外面に添えられ、釘、タッピングスクリュなどにより部材に一体的に接合されるため、木材に固有の質感が損われる上に、木質部材を補強すると言うよりは、強度の高い補強金物に強度を負担させることになり、補強金物の強度により、その部分の強度が定ってしまう。   Therefore, as a reinforcing structure, there is a structure in which a wooden member is reinforced by attaching a flat reinforcing metal member such as a strip metal or other steel plate such as a joint metal to the outer surface. However, these reinforcement hardware is generally attached to the outer surface of the wooden member and is integrally joined to the member by a nail, a tapping screw, etc., so that the inherent texture of the wood is impaired and the wooden member is reinforced. This causes the strength to be borne by the high-strength reinforcing hardware, and the strength of the portion is determined by the strength of the reinforcing hardware.

また、該種補強金物は鋼板製であり、肉厚も薄いため、幅方向に対する強度は高いものの、肉厚方向の曲げ強度は低く、簡単に折れ曲りやすい。このため接合部分に応力が加わると釘などがゆるんで、木質部材との間にがたが生じたり、剥がれやすい。   Further, since the seed reinforcement hardware is made of a steel plate and has a small thickness, the strength in the width direction is high, but the bending strength in the thickness direction is low, and it is easily bent. For this reason, when stress is applied to the joint portion, the nail or the like is loosened, and rattling is likely to occur or peel off from the wooden member.

尚、本出願人は、下記特許文献１で示す木質部材の接合構造を提案している。これは例えば、土台と柱の接合部にそれぞれほぞ穴及びを凹部形成しておき、このほぞ穴及び凹部に木質板からなるほぞ部材を嵌合して接合する。   In addition, this applicant has proposed the joining structure of the wooden member shown by the following patent document 1. FIG. For example, mortises and recesses are respectively formed in the joints between the base and the pillars, and tenon members made of a wooden board are fitted and joined to the mortises and the recesses.

そして、ほぞ部材の片面または両面には予め鋼板を重合しておき、嵌め合い状態で、土台の側面からほぞ部側に向けて複数の線状接合具を打込み、鋼板を貫通させて土台−柱間を接合するものである。   Then, a steel plate is preliminarily superposed on one side or both sides of the tenon member, and in a fitted state, a plurality of linear joints are driven from the side surface of the base toward the tenon side, and the base plate-pillar is penetrated through the steel plate. It is what joins.

この接合構造によれば、補強金具が接合位置の外面に露出せず、単に接合具の頭部が見えるだけであり、木質部材の質感を損うことがない。また、接合部の内部で木質部材と一体化し、接合箇所を補強するため、接合部に力が加わっても、容易には変形が生ずることがなく、木質部材と協働して外力に対抗する。
特開２００１−２４５０３４号公報 According to this joining structure, the reinforcing metal fitting is not exposed on the outer surface of the joining position, and only the head of the joining tool can be seen, and the texture of the wooden member is not impaired. In addition, since it is integrated with the wooden member inside the joint and reinforces the joint portion, even if a force is applied to the joint, deformation does not easily occur, and it works against the external force in cooperation with the wooden member. .
JP 2001-245034 A

この構造においては、土台に対する柱の接合箇所のように、その補強位置を部材間の接合位置に限定して補強を行っている。   In this structure, the reinforcement position is limited to the joining position between the members, as in the joining part of the column to the base.

しかし木質部材のうち、両端固定され、その長手方向と直交する方向の荷重を分担する部材、例えば大引き、梁、あるいはこれと直交配置される根太などの横架材にあっては、床板を介してその長手方向と直交する鉛直荷重が常時加わっている。   However, among wooden members, members that are fixed at both ends and share the load in the direction orthogonal to the longitudinal direction, for example, horizontal members such as large draws, beams, or joists placed orthogonal to the floor plate, Therefore, a vertical load perpendicular to the longitudinal direction is constantly applied.

また、柱や間柱などの縦材においても地震時に大きな横力が加わると、その両端の他部材との接合位置が補強されていたとしても、材そのものの中央部に大きな剪断力が作用すると、縦材そのものが折れる可能性もある。   In addition, when a large lateral force is applied to a vertical member such as a column or a stud during an earthquake, even if the joint position with other members at both ends is reinforced, a large shearing force acts on the central part of the material itself, The vertical member itself may break.

そこで本発明は、以上の課題を解決するものであって、その目的とするところは、簡単な構造を付加することで、木質部材に固有の質感を損うことなく、また他部材との接合位置によらず、木質部材の荷重作用位置を補強出来るようにした木質部材の補強構造を提供することにある。   Therefore, the present invention solves the above-described problems, and the object of the present invention is to add a simple structure so as not to impair the texture unique to the wooden member and to join with other members. An object of the present invention is to provide a reinforcing structure for a wooden member that can reinforce the load acting position of the wooden member regardless of the position.

前記目的を達成するため、請求項１の発明に係る木質部材の補強構造発明は、図１、２の第１の実施の形態にも示すように、両端固定された角材や丸材など長手の横架材よりなる木質部材１の中央部に、その長手方向に沿って、スリット２を形成し、該スリット２内に補強板３を挿入して埋設するとともに、該補強板３と直交して前記木質部材１の側面よりこれを貫通する複数のタッピングネジなどよりなる線状の金属接合具４を打込んで木質部材１内部に前記補強板３を固定したことを特徴とする。 In order to achieve the above object, the invention for reinforcing a wooden member according to the first aspect of the present invention is a longitudinal horizontal structure such as a square member or a round member fixed at both ends as shown in the first embodiment of FIGS.

The reinforcing plate 3 is fixed inside the wooden member 1 by driving a linear metal connector 4 made of a plurality of tapping screws or the like penetrating from the side surface of the wooden member 1.

スリット２は、側面形状が略矩形状であり、木質部材を貫通して形成してもよく、木質部材内に深く凹溝により形成しても良い。補強板３は、一般には、スリット２の形状に沿い、スリット２内に嵌挿される肉薄矩形状の鉄板などの金属板により形成される。補強板３を繊維強化樹脂板などのプラスチック板により形成することも可能である。   The slit 2 has a substantially rectangular side surface, and may be formed through the wood member, or may be formed by a deep groove in the wood member. The reinforcing plate 3 is generally formed of a metal plate such as a thin rectangular iron plate that is inserted into the slit 2 along the shape of the slit 2. It is also possible to form the reinforcing plate 3 with a plastic plate such as a fiber reinforced resin plate.

請求項２の発明は、図３の第２の実施形態に示すように、前記スリットが前記木質部材の幅方向に２つ以上平行に形成され、この２つ以上のスリットの夫々に補強板が嵌挿固定されていることを特徴としている。   In the second aspect of the invention, as shown in the second embodiment of FIG. 3, two or more slits are formed in parallel to the width direction of the wooden member, and a reinforcing plate is provided in each of the two or more slits. It is characterized by being fitted and fixed.

請求項５の発明は、図４の第３の実施形態に示すように、前記スリット２が前記木質部材１の幅方向に２つ以上平行して配列された木質部材において、前記補強板１０が断面略コ字形をなし、該コ字形補強板１０の背面板部１０ｂを木質部材１の荷重作用方向（上面又は下面）に露出した状態でスリット２内に嵌合固定されたことを特徴とする。   According to a fifth aspect of the present invention, as shown in the third embodiment of FIG. 4, in the wooden member in which two or more slits 2 are arranged in parallel in the width direction of the wooden member 1, the reinforcing plate 10 is It has a substantially U-shaped cross section, and is fitted and fixed in the slit 2 with the back plate portion 10b of the U-shaped reinforcing plate 10 exposed in the load acting direction (upper surface or lower surface) of the wooden member 1. .

請求項６の発明は、図５の第４実施形態に示すように、両端固定された長手の横架材よりなる木質部材の中央部にほぞ穴を形成し、該ほぞ穴が形成された木質部材中央部の上面に、下端中央に凹部が形成された柱を立設し、両側面に接合補強板が積層された木栓を前記ほぞ穴と前記凹部に嵌合し、ほぞ穴の両外側部に接して、長手方向に沿って、左右のスリットを形成し、該左右のスリット内に補強板を挿入して埋設するとともに、補強板、接合補強板及び木栓と直交して前記木質部材の側面よりこれを貫通する複数の線状接合具を打込んで木質部材内部に前記補強板、接合補強板及び木栓を固定した木質部材の補強構造を特徴としている。According to the sixth aspect of the present invention, as shown in the fourth embodiment of FIG. 5, a mortise is formed in the center of a wooden member made of a long horizontal member fixed at both ends, and the wood having the mortise formed therein. A column with a recess formed in the center of the lower end is erected on the upper surface of the central part of the member, and a wooden plug in which bonding reinforcing plates are laminated on both sides is fitted into the mortise and the recess, and both outer sides of the mortise The left and right slits are formed along the longitudinal direction in contact with the portion, the reinforcing plate is inserted and embedded in the left and right slits, and the wooden member is orthogonal to the reinforcing plate, the joining reinforcing plate and the wooden plug. It is characterized by a reinforcing structure of a wooden member in which a plurality of linear joints penetrating from the side face are driven and the reinforcing plate, the joining reinforcing plate and the wooden plug are fixed inside the wooden member.

請求項１の発明によれば、補強板は木質部材内部に埋設されるため、木材固有の質感を損うことがない。荷重の作用方向は補強板の幅方向であり、補強板の内外面方向からの荷重は木質部材によって保護されていることから、補強板の肉厚は薄くても木質部材と協働して強固な剪断耐力を得ることが出来る。   According to the first aspect of the present invention, the reinforcing plate is embedded in the wooden member, so that the texture unique to the wood is not impaired. The direction of the load is the width direction of the reinforcing plate, and the load from the inner and outer surface direction of the reinforcing plate is protected by the wooden member. Therefore, even if the thickness of the reinforcing plate is thin, it is strong in cooperation with the wooden member. High shear strength can be obtained.

請求項２の発明によれば、補強板が２つ以上埋設固定されることで、さらなる剪断耐力を得ることが出来る。   According to the invention of claim 2, it is possible to obtain further shear strength by embedding and fixing two or more reinforcing plates.

本発明では、補強板の材質に応じた特性や補強効果を得ることが出来る。例えば鋼板の場合には安価となるし、ステンレス鋼板の場合には、発錆がなく、耐久性に優れる。さらに、繊維強化樹脂板（以下ＦＲＰと称する）の場合には高強度である上に軽量に出来るなどの特性がある。   In this invention, the characteristic according to the material of a reinforcement board and the reinforcement effect can be acquired. For example, in the case of a steel plate, it is inexpensive, and in the case of a stainless steel plate, there is no rusting and excellent durability. Further, in the case of a fiber reinforced resin plate (hereinafter referred to as FRP), there are characteristics such as high strength and light weight.

請求項５の発明によれば、補強板が断面コ字形に連結されていることにより、部材側面側からの曲げ耐力も向上する。また、木質部材に対する補強板の取り付け固定も容易である。   According to the invention of claim 5, since the reinforcing plate is connected in a U-shaped cross section, the bending strength from the side surface of the member is also improved. In addition, it is easy to attach and fix the reinforcing plate to the wooden member.

以下、本発明の最良の実施の形態につき、添付図面を参照して詳細に説明する。図１，２は本発明の第１実施形態を示す。   The best mode for carrying out the present invention will be described below in detail with reference to the accompanying drawings. 1 and 2 show a first embodiment of the present invention.

図１（ａ）において、角材（丸材でも可）よりなる長手の木質部材１の長手方向中央にはこれに沿った方向であって部材断面方向に一本のスリット２が貫通形成されている。このスリット２にはこれと略同一縦横寸法であって、スリット２の厚み寸法にほぼ等しい肉薄の金属補強板３が嵌挿埋設される。   In FIG. 1A, a single slit 2 is formed in a longitudinal direction center of a longitudinal wood member 1 made of square wood (or round wood) in a direction along the longitudinal direction and in a member cross-sectional direction. A thin metal reinforcing plate 3 having substantially the same vertical and horizontal dimensions as the slits 2 and substantially equal to the thickness dimension of the slits 2 is inserted and embedded in the slits 2.

埋設状態では、図１（ｂ）に示すように、木質部材１の一側面より補強板３に向けてドリルなどにより複数の下穴１ａが千鳥状に形成される。この下穴１ａの深さは少なくとも、前記補強板３を十分に貫通する深さであって、木質部材１の他方側に貫通しない程度に設定されている。   In the embedded state, as shown in FIG. 1 (b), a plurality of pilot holes 1 a are formed in a staggered pattern by a drill or the like from one side surface of the wooden member 1 toward the reinforcing plate 3. The depth of the pilot hole 1a is at least deep enough to penetrate the reinforcing plate 3 and not to penetrate the other side of the wooden member 1.

次いで各下穴１ａには線状の金属接合具４としてのタッピングネジがねじ込まれる。この接合具４ネジのネジ頭部は図の一部に拡大して示すように、皿状であって、全ての接合具４がねじ込まれた状態では、図１（ｃ）に示すように、補強板３を貫通した状態で木質部材１内で一体化され、かつネジ頭部は木質部材１の側面と同一面となり、補強体が完成する。   Next, a tapping screw as a linear metal connector 4 is screwed into each pilot hole 1a. As shown in FIG. 1 (c), the screw head of the connector 4 screw has a dish shape as shown in an enlarged view of a part of the figure, and when all the connectors 4 are screwed in, The reinforcing member 3 is integrated in the wooden member 1 in a state of passing through the reinforcing plate 3, and the screw head is flush with the side surface of the wooden member 1 to complete the reinforcing body.

前記補強板３は、鋼板、ステンレス鋼板、などの金属板、又はＦＲＰ板材などのプラスチック板などの中から選ぶことが出来る。このうち、鋼板を選択した場合には、その表面には防錆用の亜鉛メッキなどを施しておくことが望ましい。また、鋼板の場合その厚みが０．６mm程度であれば、十分な補強効果を発現できる。   The reinforcing plate 3 can be selected from metal plates such as steel plates and stainless steel plates, or plastic plates such as FRP plates. Among these, when a steel plate is selected, it is desirable to give rust-proof galvanizing to the surface. In the case of a steel plate, if the thickness is about 0.6 mm, a sufficient reinforcing effect can be exhibited.

なお、スリット２を形成した段階で下穴１ａを形成し、補強板３に対する挿通は接合具４のねじ込み時の貫通力のみで貫通させて木質部材１の内部に一体化することもできる。また、木質部材１の一方の側面からだけでなく、他方の側面から接合具４を交互ねじ込みすることも出来、同一本数でのネジ打込み部位の支持強度の左右平均化を図ることが出来る。また、金属棒状の接合具を用い、その両端を木質部材１の両側に突出させ、接合部両端のネジ部にナットを螺締させるなどの方法で固定させるようにしても良い。   In addition, the pilot hole 1a can be formed in the stage which formed the slit 2, and the penetration with respect to the reinforcement board 3 can be penetrated only by the penetration force at the time of screwing of the connector 4, and can also be integrated in the inside of the wooden member 1. FIG. Moreover, the connector 4 can be screwed alternately from not only one side surface of the wooden member 1 but also from the other side surface, so that the left and right average of the support strength of the screw driving site can be achieved with the same number. Moreover, you may make it fix by the method of using a metal rod-shaped joining tool, projecting the both ends to the both sides of the wooden member 1, and screwing a nut to the thread part of both ends of a joining part.

以上の補強構造を具備した木質部材１を横架材として使用した場合に、図２（ａ）に示すようにその上部から長手直交方向に剪断荷重Ｆが作用すると、木質部材単体では剪断破壊される程度の荷重であっても、図２（ｂ）に示すごとく、補強板３の介在により、弾性変形範囲内にとどまる。このとき荷重は補強板３のみでなく、接合具４を介して木質部材１も分担し、両者協働して剪断力に対抗するものとなり、剪断荷重Ｆが取除かれると、元の直線状に弾性復帰するものとなる。   When the wooden member 1 having the above-described reinforcing structure is used as a horizontal member, if a shear load F acts in the longitudinal orthogonal direction from the upper portion as shown in FIG. Even if it is a certain load, as shown in FIG.2 (b), it will remain in the elastic deformation range by interposition of the reinforcement board 3. FIG. At this time, not only the reinforcing plate 3 but also the wooden member 1 is shared through the connector 4, and both cooperate to counter the shearing force. When the shearing load F is removed, the original linear shape is obtained. It will return to elasticity.

なお、前記鋼板に替えてステンレス鋼板、あるいはプラスチック板なども採用可能である。ステンレス鋼板の場合には、前記のごとき防錆処理が不要であるとともに、靱性も高いため、さらに肉厚を薄くすることが出来る。またＦＲＰ板の場合には軽量高強度となる。   In addition, a stainless steel plate or a plastic plate can be used instead of the steel plate. In the case of a stainless steel plate, the rust prevention treatment as described above is unnecessary and the toughness is high, so that the wall thickness can be further reduced. In the case of an FRP plate, it is lightweight and strong.

次に、図３（ａ），（ｂ）は本発明の第２実施形態を示すものである。なお、図において、前記と同一部分には同一記号を用いて説明する。図において、木質部材の長手方向に形成されるスリット２は、木質部材１の幅方向に２つ平行して貫通形成され、各スリット２内に補強板３が埋設され、複数の接合具４によって木質部材１内に一体化されている点、及び接合具４の長さも、両補強板３を貫通するに十分な長さに形成されている点が異なるのみでその他は第１実施形態と同様である。   Next, FIGS. 3A and 3B show a second embodiment of the present invention. In the figure, the same parts as those described above will be described using the same symbols. In the figure, two slits 2 formed in the longitudinal direction of the wooden member 1 are formed so as to penetrate in parallel with the width direction of the wooden member 1, and a reinforcing plate 3 is embedded in each slit 2. The other points are the same as those of the first embodiment except that they are integrated in the wood member 1 and the length of the connector 4 is different from that of the wood member 1 in that the length is sufficiently long to penetrate both the reinforcing plates 3. It is.

本実施形態では、第１実施形態の２倍の剪断耐力となる。なお、補強板３を３枚以上埋設する構造とすることもできるが、木材強度や木材の断面積等の点を考慮して埋設数を設定すればよい。   In this embodiment, the shear strength is twice that of the first embodiment. In addition, although it can also be set as the structure which embeds three or more reinforcement boards 3, it should just set the number of embed | buried in consideration of points, such as timber strength and a cross-sectional area of timber.

図４（ａ），（ｂ）は本発明の第３実施形態を示すものである。図において、木質部材１には平行な２つのスリット２が形成されているとともに、各スリット２に埋設される補強板１０は、平行な一対の補強板本体１０ａと補強板本体１０ａの頂部で一体化された背面板部１０ｂとからなる断面略コ字形をなしており、図４（ｂ）に示す組立状態では、前記背面板部１０ｂが木質部材１の頂部に露出している。   4 (a) and 4 (b) show a third embodiment of the present invention. In the figure, two parallel slits 2 are formed in the wood member 1, and the reinforcing plate 10 embedded in each slit 2 is integrated with a pair of parallel reinforcing plate main body 10a and the top of the reinforcing plate main body 10a. The rear plate portion 10b has a substantially U-shaped cross section, and the back plate portion 10b is exposed at the top of the wooden member 1 in the assembled state shown in FIG.

本実施形態では、図４（ｂ）の矢印に示すように、木質部材１の上部側からの長手直交方向に作用する剪断荷重Ｆに対する耐力を十分に得られると同時に、側面側からの長手直交方向に作用する剪断荷重Ｆ１に対しては背面板部１０ｂがその荷重を分担して支えることになるため、垂直、水平方向とも剪断耐力を得ることが出来る。
本実施形態において、背面板部１０ｂが木質部材１の下面側となるように下面側から補強板１０を嵌挿することも可能である。 In the present embodiment, as shown by the arrow in FIG. 4B, sufficient resistance to the shear load F acting in the longitudinal orthogonal direction from the upper side of the wooden member 1 can be obtained, and at the same time, the longitudinal orthogonal from the side surface side. Since the back plate 10b shares and supports the shear load F1 acting in the direction, shear strength can be obtained in both the vertical and horizontal directions.
In this embodiment, it is also possible to insert the reinforcing plate 10 from the lower surface side so that the back plate portion 10b is on the lower surface side of the wooden member 1.

図５（ａ），（ｂ）は、本発明の補強構造を土台と柱との仕口部に適用した第４実施形態を示している。図５（ａ）において、土台２０にはほぞ穴２１が加工され、ほぞ穴２１の両外側部に接して、長手方向に沿ってスリット２が開口されている。一方、柱２２の下部中央には凹部２３が形成され、この凹部２３とほぞ穴２３の双方に嵌合する接合用の木栓２４及びこの木栓２４の両面に積層された鋼板などの接合補強板２５が設けられている。   5 (a) and 5 (b) show a fourth embodiment in which the reinforcing structure of the present invention is applied to a joint portion between a base and a pillar. In FIG. 5A, a mortise 21 is machined in the base 20, and the slit 2 is opened along the longitudinal direction in contact with both outer side portions of the mortise 21. On the other hand, a recess 23 is formed in the lower center of the column 22, and a joining wooden plug 24 that fits into both the concave 23 and the mortise 23 and joining reinforcement such as steel plates laminated on both sides of the wooden plug 24. A plate 25 is provided.

以上において、両スリット２に補強板３を嵌合埋設し、次いで木栓２４を接合補強板２５とともにほぞ穴２１に嵌め付け、次いで柱２２の凹部２３を木栓２４と接合補強板２５の積層体に嵌め付け、次いで、複数のネジ接合具４を補強板３及び積層***置に向けてねじ込むことで、図５（ｂ）に示すように、土台２０と柱２２間の接合を行えるとともに、この接合位置周辺において土台２０の剪断耐力も確保することになる。   In the above, the reinforcing plate 3 is fitted and embedded in both the slits 2, and then the wooden plug 24 is fitted into the mortise 21 together with the joining reinforcing plate 25, and then the concave portion 23 of the pillar 22 is laminated with the wooden plug 24 and the joining reinforcing plate 25. Next, as shown in FIG. 5 (b), the base 20 and the pillar 22 can be joined by screwing them into the body and then screwing the plurality of screw joints 4 toward the reinforcing plate 3 and the laminated body position. The shear strength of the base 20 is also secured around the joining position.

また、土台−柱間のみでなく、各種接合部を補強することも可能であり、横架材だけでなく、縦材などにも以上の補強構造とすることも可能であることは勿論である。   In addition, it is possible to reinforce various joints as well as between the base and the pillar, and of course, it is possible to have the above reinforcing structure not only for horizontal members but also for vertical members. .
