Description
本発明は、木質の柱部材と木質の梁部材とを接合した柱梁接合構造および柱梁接合方法に関するものである。 TECHNICAL FIELD The present invention relates to a beam-column joint structure and a beam-joint method in which a wooden column member and a wooden beam member are joined.
従来、木質の柱部材と木質の梁部材、あるいは鋼材を内蔵した木製の梁部材とを接合する場合、引きボルトとドリフトピンを併用した鋼板挿入2面剪断型の柱梁接合構造が一般的に用いられている(例えば、特許文献1、2を参照)。図3に示すように、この従来の柱梁接合構造は、木質の柱部材1に水平に挿通配置した複数の通しボルト2(引きボルト)およびナット2aを介して平面視でT字状断面の梁部材接続用の金物3のベースプレート3aを柱1の側面の凹部1aに取り付ける一方、梁部材接続用の金物3のガセットプレート3bを木質の梁部材4の端面の凹溝部4aに挿入配置し、ガセットプレート3bと梁部材4とをドリフトピン5などの接合具にて接続したものである。なお、図の例では、梁部材4の上面にラグスクリューボルト6を介してスラブコンクリート7が設けられ、ドリフトピン5の端部側に木栓8が埋め込み配置され、柱部材1の側面の凹部1aの縁部にモルタルバーなどの断熱材9が配置された例を示している。 Conventionally, when joining a wooden column member and a wooden beam member, or a wooden beam member containing a steel material, a steel plate inserted two-side shear type column-beam joint structure using a pull bolt and a drift pin is generally used. (For example, see Patent Documents 1 and 2). As shown in FIG. 3, this conventional beam-column joint structure has a T-shaped cross section in plan view through a plurality of through bolts 2 (pull bolts) and nuts 2a that are horizontally inserted through a wooden pillar member 1 and arranged. The base plate 3a of the metal member 3 for connecting the beam member is attached to the concave portion 1a on the side surface of the pillar 1, and the gusset plate 3b of the metal member 3 for connecting the beam member is inserted and arranged in the concave groove 4a on the end surface of the wooden beam member 4. The gusset plate 3b and the beam member 4 are connected by a connector such as a drift pin 5. In the example shown in the figure, slab concrete 7 is provided on the upper surface of the beam member 4 via a lag screw bolt 6, a wooden plug 8 is embedded and arranged on the end side of the drift pin 5, and a concave portion on the side surface of the column member 1. An example in which a heat insulating material 9 such as a mortar bar is arranged at the edge of 1a is shown.
しかしながら、こうした柱梁接合構造においては、接合に起因する剛性や耐力の低下が大きく、接合効率が低いことが問題となっていた。また、一定階数以上の架構を計画する場合、通し柱以外にも対応可能な汎用ディテールが必要となる。上記の問題に対しては、例えばRC(鉄筋コンクリート)接合部などの木材よりも硬質の材料からなる仕口部材を採用することで、接合効率を大幅に上昇させることができる(例えば、特許文献3を参照)。この場合、仕口部材と、仕口部材の上端面に配置される上側柱部材と、仕口部材の下端面に配置される下側柱部材との接続に、既往技術のグルードインロッド(以下、GIRということがある。)接合を用いることが有効であるが、以下のような問題があった。 However, in such a beam-column joint structure, the rigidity and proof stress caused by the joint are greatly reduced, and the joining efficiency is low. In addition, when planning a frame with a certain number of floors or more, general-purpose details that can be used besides through columns are required. In order to solve the above problem, for example, by adopting a connection member made of a material harder than wood, such as a RC (reinforced concrete) joint, the joining efficiency can be greatly increased (for example, Patent Document 3). See). In this case, the connection between the connection member, the upper column member disposed on the upper end surface of the connection member, and the lower column member disposed on the lower end surface of the connection member is performed using a glue-in rod (hereinafter, referred to as a conventional technology). , GIR.) Although it is effective to use a junction, there are the following problems.
図4(a)に示すように、異形鉄筋A1を木材A2(集成材)に挿入し、エポキシ系接着剤A3にて定着させるタイプのGIR接合は、適用事例も多く一般的であるが、鉄筋A1の節部に集中的に木材A2を押し広げる力が作用するため、割裂破壊しやすく脆性的な性状を有する。 As shown in FIG. 4 (a), GIR joining of a type in which deformed reinforcing bar A1 is inserted into wood A2 (laminate) and fixed with epoxy adhesive A3 is common in many application examples. Since the force for pushing and spreading the wood A2 acts intensively on the nodes of A1, the wood is easily split and fractured and has brittle properties.
図4(b)に示すように、ネジ部A41と丸鋼部A42からなる鋼棒A4(転造ねじアンカーボルト)のネジ部A41を木材A2に挿入し、エポキシ系接着剤A3にて定着させるタイプのGIR接合は、鋼棒A4が十分に塑性変形するまで割裂破壊しにくく、図5に示すように靱性的な破壊形式となることが実験的に確認されている。なお、図5は、断面寸法が150mm×150mmの木材に鋼棒(異形鉄筋、転造ねじアンカーボルト)をGIR接合にて500mmの長さだけ定着させた場合の引張試験結果である。 As shown in FIG. 4B, the screw portion A41 of the steel rod A4 (rolled screw anchor bolt) composed of the screw portion A41 and the round steel portion A42 is inserted into the wood A2, and fixed with the epoxy adhesive A3. It has been experimentally confirmed that this type of GIR joint hardly splits and fractures until the steel bar A4 is sufficiently plastically deformed, and has a tough fracture mode as shown in FIG. FIG. 5 shows a tensile test result when a steel bar (deformed rebar, rolled screw anchor bolt) is fixed by GIR bonding to a length of 500 mm on wood having a cross-sectional dimension of 150 mm × 150 mm.
耐火仕上材を有する柱の場合には特に、GIRのエポキシ系接着剤の注入作業を現場にて行うことは仕上の後遣り工程が増え、労力を要する。そこで、既に工場もしくはサイトにてGIR鋼棒を挿入した木質の柱部材を用意し、建方時には接合部内にて上下の柱部材から突出した鋼棒を接合するのみとすることが現実的である。しかしながら、上記の靱性的なネジ形状の鋼棒を用いる場合、上下の柱部材にそれぞれ固定された鋼棒同士の接合に対する汎用的な手段がないという問題がある。 In particular, in the case of a pillar having a refractory finish, performing the work of injecting the GIR epoxy-based adhesive on site increases the number of post-processing steps for the finish and requires labor. Therefore, it is realistic to prepare a wooden pillar member in which a GIR steel rod is already inserted at a factory or a site, and only join the steel bars projecting from the upper and lower pillar members in the joint at the time of construction. . However, when the tough screw-shaped steel rod is used, there is a problem that there is no general-purpose means for joining the steel rods fixed respectively to the upper and lower column members.
このため、木質の柱部材と梁部材の柱梁接合構造において、接合部の上下の柱部材にそれぞれ固定された鋼棒同士を容易に一体化接合することのできる施工性に優れた技術が求められていた。 For this reason, in a beam-column joint structure between a wooden pillar member and a beam member, there is a need for a technique excellent in workability capable of easily integrally joining steel rods respectively fixed to upper and lower pillar members at the joint. Had been.

It is characterized in that deformed reinforcing bars of steel bars are joined.

以下に、本発明に係る柱梁接合構造および柱梁接合方法の実施の形態を図面に基づいて詳細に説明する。なお、この実施の形態によりこの発明が限定されるものではない。 Hereinafter, embodiments of a beam-column joint structure and a beam-column joint method according to the present invention will be described in detail with reference to the drawings. The present invention is not limited by the embodiment.
図1に示すように、本発明に係る柱梁接合構造10は、木質の角型断面の柱部材12と木質の角型断面の梁部材14とを、RCで構成された仕口部材16を介して接合してなる構造である。仕口部材16の側端面には梁部材14と接続するためのウェブ16A(突出金物)が設けられている。 As shown in FIG. 1, a beam-column joint structure 10 according to the present invention includes a wooden member 16 having a rectangular cross section and a wooden member 14 having a rectangular cross section. It is a structure that is joined through the intermediary. A web 16 </ b> A (a protruding hardware) for connecting to the beam member 14 is provided on a side end surface of the connection member 16.
仕口部材16の上下にはベースモルタル32を介して上側柱部材12Aおよび下側柱部材12Bが配置される。仕口部材16、上側柱部材12A、下側柱部材12Bの平面視で4隅側には、それぞれ鋼棒22が上下方向に挿入配置される。図の例ではGIR接合の場合を示している。鋼棒22は異形鉄筋部22Bとネジ形状のネジ部22Aとからなる切削鉄筋であり、ネジ部22Aは上側柱部材12Aおよび下側柱部材12Bに挿入配置されてエポキシ系接着剤等を介してここに付着固定され、異形鉄筋部22Bは仕口部材16に主筋として挿入配置されて鉄筋継手18、20に接合される。鉄筋継手18、20の間には異形鉄筋24が配置されている。仕口部材16の内部の異形鉄筋部22Bの周囲には複数のフープ筋28が巻回配置されている。 An upper column member 12A and a lower column member 12B are arranged above and below the connection member 16 via a base mortar 32. Steel rods 22 are vertically inserted at four corners of the connection member 16, the upper column member 12A, and the lower column member 12B in plan view. The example of the figure shows the case of a GIR junction. The steel bar 22 is a cutting reinforcing bar including a deformed reinforcing bar portion 22B and a screw-shaped screw portion 22A. The screw portion 22A is inserted and arranged in the upper column member 12A and the lower column member 12B, and is interposed through an epoxy adhesive or the like. Here, the deformed reinforcing bar portion 22B is inserted and arranged as a main reinforcing bar in the connection member 16 and joined to the reinforcing bar joints 18 and 20. A deformed reinforcing bar 24 is disposed between the reinforcing bar joints 18 and 20. A plurality of hoop bars 28 are wound around the deformed reinforcing bar portion 22 </ b> B inside the connection member 16.
このように、本実施の形態では、柱部材12と仕口部材16との接続に際し、GIRの鋼棒22に切削鉄筋を用いる。切削鉄筋は、図2に示すように異形鉄筋の片側をネジ形状に切削加工したものである。切削鉄筋からなる鋼棒22のネジ部22A側を柱部材12内に挿入配置することで木材の割裂破壊を防止して靱性的な性状を確保する。一方の異形鉄筋部22B側を仕口部材16内に挿入配置することで通常のPC(プレキャストコンクリート)用スリーブ系の鉄筋継手18、20(例えばスリーブジョイント)の利用が可能となり、建方時には仕口部材16内にて上側柱部材12Aおよび下側柱部材12Bから突出した切削鉄筋の異形鉄筋部22Bを接合するのみとすることができる。この方法によれば現位置でのエポキシ系接着剤の注入作業は生じない。なお、図1の例では鉄筋継手18、20を仕口部材16内の上下2か所に設けているが、例えば下側柱部材12Bから上方に突出する異形鉄筋部22Bを仕口部材16内の上方まで延長すれば鉄筋継手を上部の1か所に低減することができる。 As described above, in the present embodiment, when connecting the column member 12 and the connection member 16, the cutting bar is used for the GIR steel rod 22. As shown in FIG. 2, the cut rebar is obtained by cutting one side of a deformed rebar into a thread shape. By inserting the screw portion 22A side of the steel rod 22 made of the cutting rebar into the column member 12, splitting and breaking of wood is prevented, and toughness is secured. By inserting one deformed reinforcing bar portion 22B side into the connecting member 16, it is possible to use the ordinary PC (precast concrete) sleeve type reinforcing bar joints 18 and 20 (for example, a sleeve joint), and to construct the joint at the time of construction. In the mouth member 16, the deformed reinforcing bar portion 22B of the cutting reinforcing bar protruding from the upper column member 12A and the lower column member 12B can only be joined. According to this method, the work of injecting the epoxy adhesive at the current position does not occur. In the example of FIG. 1, the rebar joints 18 and 20 are provided at two upper and lower positions in the connection member 16. For example, the deformed rebar portion 22 </ b> B protruding upward from the lower column member 12 </ b> B Can be reduced to one upper part.
仕口部材16と梁部材14との接合は、引きボルト34とドリフトピン38を併用した鋼板挿入2面剪断型接合ディテール(図3を参照)を用いる。なお、図1において、符号36はナット、符号40はベースプレートである。仕口部材16がRCであることから引きボルト34部分に起因する接合効率の低下を防止することができ、引きボルト34との一体性が高まるため、一般的な木質接合部にて同様のディテールを採用した場合と比較して接合効率の増大を期待することができる。仕口部材16内の引きボルト34の付着性能を高めるため、引きボルト34には全ネジボルト、あるいは図2に示したような方法で両端をネジ加工した切削鉄筋を用いることもできる。 The joint between the connection member 16 and the beam member 14 uses a steel plate insertion two-surface shearing type joint detail (see FIG. 3) using both the pull bolt 34 and the drift pin 38. In FIG. 1, reference numeral 36 denotes a nut, and reference numeral 40 denotes a base plate. Since the connection member 16 is made of RC, it is possible to prevent a decrease in joining efficiency due to the pull bolt 34, and to increase the integrity with the pull bolt 34. It can be expected that the joining efficiency will be increased as compared with the case where is adopted. In order to enhance the adhesion performance of the pull bolt 34 in the connection member 16, the pull bolt 34 may be a full screw bolt or a cutting rebar whose both ends are threaded by a method as shown in FIG. 2.
上記の実施の形態において、仕口部材16はPC化(プレキャストコンクリート化)したものを用いてもよい。その場合、予め鉄筋継手18、20が設けられた仕口部材16の上下に、鋼棒22の異形鉄筋部22Bが突出した上側柱部材12Aおよび下側柱部材12Bを配置した後、異形鉄筋部22Bと鉄筋継手18、20とを接合することで、上記の柱梁接合構造10を構築することもできる。なお、上述したように仕口部材16の内部に鉄筋継手を1か所しか設けない場合は、仕口部材16内に上下方向の主筋(異形鉄筋部22B)を通すための孔を開けておき、異形鉄筋部22Bを挿入後にグラウト充填すればよい。 In the above embodiment, the connection member 16 may be made of PC (precast concrete). In this case, after the upper column member 12A and the lower column member 12B from which the deformed reinforcing bar portion 22B of the steel bar 22 protrudes are disposed above and below the connection member 16 in which the reinforcing bar joints 18 and 20 are provided in advance, the deformed reinforcing bar portion The beam-column joint structure 10 described above can also be constructed by joining the reinforcing joints 22 and 22B to the rebar joints 18 and 20. When only one reinforcing joint is provided inside the connection member 16 as described above, a hole is formed in the connection member 16 for passing a main reinforcing bar (deformed reinforcing bar portion 22B) in the vertical direction. The grout may be filled after inserting the deformed reinforcing portion 22B.
このように、本実施の形態によれば、柱部材12と仕口部材16との接続を、切削鉄筋からなる鋼棒22を用いたGIR接合とすることで、靱性を有し、かつ施工性に優れたディテールを実現することができる。これにより柱梁接合構造10の剛性、耐力、靱性を確保することで、ラーメン架構以外の耐震要素を減少させ、高い空間自由度を実現することができると同時に意匠性に優れた木質空間を提供することが可能である。 As described above, according to the present embodiment, the connection between the column member 12 and the connection member 16 is performed by GIR bonding using the steel rod 22 made of a cutting rebar, thereby having toughness and workability. Excellent detail can be realized. As a result, by securing the rigidity, strength and toughness of the beam-column joint structure 10, seismic elements other than the ramen frame can be reduced, and a high degree of freedom in space can be realized, and at the same time, a wooden space excellent in design can be provided. It is possible to
また、切削鉄筋については、通常の異形鉄筋に対して十分な長さのネジ切削加工を施す技術が存在している。本発明においては、その他のディテールも全て既存技術にて構成することが可能なため、施工性に優れ、かつ低コストの柱梁接合構造を実現することができる。また、接合部の取合が明快なため、被覆等の耐火仕様の納りも容易となる。 Further, as for the cutting rebar, there is a technique of performing a sufficient length of thread cutting on a normal deformed rebar. In the present invention, since all the other details can be configured by the existing technology, it is possible to realize a column-beam joint structure excellent in workability and low in cost. In addition, since the connection of the joints is clear, it is easy to accommodate fireproof specifications such as coating.
以上説明したように、本発明に係る柱梁接合構造によれば、木質の柱部材と木質の梁部材とを木材よりも硬質の材料からなる仕口部材を介して接合してなる柱梁接合構造であって、仕口部材の側端面に設けられ、梁部材と接続するための突出金物と、仕口部材とその上下にそれぞれ設けられる上側柱部材および下側柱部材とを接続するために上下方向に挿入配置される鋼棒とを備え、鋼棒は異形鉄筋部とネジ形状のネジ部とからなり、ネジ部は上側柱部材および下側柱部材に挿入配置されてここに付着固定され、異形鉄筋部は仕口部材に挿入配置されて鉄筋継手に接合されるので、上側柱部材および下側柱部材にそれぞれ付着固定された鋼棒同士を容易に一体化接合することのできる施工性に優れた柱梁接合構造を提供することができる。 As described above, according to the beam-column joint structure of the present invention, a beam-column joint formed by joining a wooden pillar member and a wooden beam member via a connection member made of a material harder than wood.
