Description

この発明は、各種目的に対応して用いられるボルトの受け金物を施工側において都合良く適宜の材に備え付け得るボルト受け金物の提供と、構造材の引き寄せ側における施工のみによって、互いに直交する向きにある各構造材を引き寄せ状態に接合することのできる引き寄せ方法の提供に関する。   The present invention provides a bolt bracket that can be used for various purposes and can be conveniently attached to an appropriate material on the construction side, and in a direction orthogonal to each other only by construction on the drawing side of the structural material. The present invention relates to the provision of a drawing method capable of joining each structural material in a drawn state.

建物の構築後における使い勝手の変更や、使用居住空間の変更等に伴う各種増改築や、耐震補強等が随時必要とされることがある。   There are cases in which it is necessary to change the facilities after building construction, various expansions and reconstructions accompanying changes in the living space used, seismic reinforcement, etc.

このような建物の増改築や、耐震補強工事等にあっては、多くの場合、増設や耐震補強される梁を既設の梁に引き寄せ接合するために新たに羽子板ボルトを当該増設梁や耐震補強梁に備え付けると共に、既設の梁の背面側において当該羽子板ボルトの締め付けをなす必要があった。   In such extension and renovation of buildings and seismic reinforcement work, in many cases, a new battledore bolt is attached to the extension beam or seismic reinforcement to attract and join the beam to be expanded or seismically strengthened to the existing beam. In addition to being provided on the beam, it was necessary to tighten the battledore bolt on the back side of the existing beam.

また、このような建物の増改築や、耐震補強工事等において、新たに柱を増設する場合や新たに柱の耐震補強をする場合、当該柱における柱頭、柱脚部分を横向きの構造材に引き寄せ組み付けるようにして、地震等に際して、当該横向きの構造材からの柱の浮き上がりや、柱上にある梁等の当該柱からの浮き上がり等を防ぐために、当該横向きに備えられている各構造材の背面側における各種施工が必要とされていた。   In addition, when a new column is added or a new column is retrofitted with seismic reinforcement, such as in an extension or renovation of such a building, the head of the column and the column base are drawn to the structural material facing sideways. In the event of an earthquake, etc., in order to prevent the column from lifting up from the sideways structural material and the beam on the column, etc. Various constructions on the side were required.

かかる点から、例えば、基礎に備えられているアンカーボルトと、柱に備えられているホールダウン金物におけるボルト挿通孔とが同一の垂直線上に位置づけられなかったような場合、この土台から突き出されているアンカーボルトを柱に備えられているホールダウン金物に連結する手段として特許文献1に示される接合金物が開示されている。   From such a point, for example, when the anchor bolt provided on the foundation and the bolt insertion hole in the hole-down hardware provided on the column are not positioned on the same vertical line, the anchor bolt is protruded from the base. As a means for connecting a fixed anchor bolt to a hole-down hardware provided on a pillar, a joint hardware disclosed in Patent Document 1 is disclosed.

この特許文献1に示される接合金物は、基礎に埋め込まれたアンカーボルトヘの接続部と柱に固定されたホールダウン金物への取付部にワイヤーロープの端末を挿入し圧縮止めした接合金物であって、接続部がアンカーボルトに螺合するナット端部を有し、取付部がホールダウン金物の取付穴に挿入するボルト端部を有するようにしてあり、また、ボルト端部を取付穴に取り付けるために介在するワツシヤが傾斜する上下面を有する構成の接合金物としてある。
特開平11−350609
The joint hardware shown in Patent Document 1 is a joint hardware in which a wire rope end is inserted into a connection portion to an anchor bolt embedded in a foundation and a mounting portion to a hole-down hardware fixed to a column and is compressed. The connection portion has a nut end portion that is screwed into the anchor bolt, the attachment portion has a bolt end portion that is inserted into the attachment hole of the hole-down hardware, and the bolt end portion is attached to the attachment hole. For this reason, it is a bonding hardware having a configuration in which the interposed washers have upper and lower surfaces that are inclined.

しかしながら、特許文献1に示される接合金物は、基礎に備えられ、かつ、土台を貫通して上方に突き出されたアンカーボルトの取扱いに関するものであって、設置されている土台に対して新たに設置される柱を引き寄せ状態に組み付ける手段や設置されている柱の耐震補強手段として用い得るものではなかった。   However, the joint hardware shown in Patent Document 1 relates to the handling of anchor bolts provided on the foundation and protruding upward through the foundation, and is newly installed on the installed foundation. It was not possible to use as a means for assembling the pillars to be pulled together or as a means for seismic reinforcement of the installed pillars.

また、新規に備えられる柱の柱頭や耐震補強される柱の柱頭にあって、この柱頭を当該柱に直交して備えられている梁等に対して引き寄せ状態に組み付けるには、当該柱に直交している梁等の構造材の上方に張り込まれている床材等を取り外して施工する必要があった。   In addition, it is in the head of a newly provided pillar or a pillar to be seismically strengthened, and in order to assemble this head with a beam or the like provided perpendicular to the pillar, it is perpendicular to the pillar. It was necessary to remove and install the floor material, etc., that was stuck above the structural material such as beams.

また、新規に梁等の横向きの構造材を当該構造材に直交する向きにある梁等の横向きの構造材に引き寄せ状態で組み付ける場合や、直交して横向きに備えられている各構造材相互の耐震補強施工等に際して、既設梁等における接合側と反対側に備えられている各種造作材や、張り込まれている壁面材等を取り外して施工する必要があった。   In addition, when a horizontally-oriented structural material such as a beam is newly assembled to a laterally-oriented structural material such as a beam in a direction orthogonal to the structural material, or between each structural material provided orthogonally and horizontally In the case of seismic reinforcement construction, it was necessary to remove the various construction materials provided on the opposite side of the existing beam, etc., and the wall materials that had been installed.

かかる従前手法にあっては、増改築や、耐震補強施工等において新規に柱や、新規に梁を容易かつ確実に組み付け設置したり、新規に耐震補強施工をなすことが難しく、新規に柱や梁等を備え付ける増改築や耐震補強施工に際して、多くの材と、多くの施工手間と、多くの施工期間とを要し、割高な施工コストとなる不具合があった。   In this conventional method, it is difficult to install and install new pillars and new beams easily and surely in extension and reconstruction, seismic reinforcement construction, etc. There was a problem that the construction cost was expensive because many materials, a lot of construction work, and a lot of construction period were required for the retrofitting and seismic reinforcement work with beams.

この発明は、かかる従前における増改築や耐震補強施工時における柱や梁等の新規設置や新規耐震補強に際して、当該柱や梁等の構造材の引き寄せを柱や梁等の新設側あるいは新規耐震補強側においてなし得るようにして、柱や梁等の新設側や耐震補強の新規施工側と反対の側にある建物部分の取り壊しや、取り外し等を要請されることの不具合を解消し、また、各種用途に対応して設置されるボルトのねじ入れ対象金物を施工側にある材に対して都合良く設置するものである。   In the present invention, when a new column or beam is newly installed or a new seismic reinforcement is carried out at the time of the conventional extension or reconstruction or seismic reinforcement, the structural material such as the column or beam is attracted to the new side of the column or beam or a new seismic reinforcement. The problem of being requested to demolish or remove the building part on the opposite side of the new construction side of pillars and beams and the new construction side of seismic reinforcement, etc. The bolts to be screwed in according to the usage are conveniently installed on the material on the construction side.

典型的には、当該ボルト受け金物10の全長よりもやや短い深さの比較的細い孔径の案内孔40bを穿ち、更に、当該ボルト受け金物10の円筒部12aが押し込まれることに伴う構造材40の割れを防ぐために当該ボルト受け金物10における軸部12の直径とほぼ同寸の内径を備える孔40cを、構造材40にねじ入れ状態に押し入れられるボルト受け金物10における軸部12のほぼ半分程度の深さまで穿ち、更に、当該ボルト受け金物10における頭部11の納まる凹部40aを座刳り工具を用いて座刳る。   Typically, the guide member 40b having a relatively small hole diameter, which is slightly shorter than the entire length of the bolt receiver 10, and the structural member 40 associated with the cylindrical portion 12a of the bolt receiver 10 being pushed in. In order to prevent cracking, a hole 40c having an inner diameter substantially the same as the diameter of the shaft portion 12 in the bolt receiver 10 is approximately half of the shaft portion 12 in the bolt receiver 10 that is pushed into the structural member 40 in a screwed state. Further, the concave portion 40a in which the head portion 11 is accommodated in the bolt receiver 10 is seated using a seating tool.

なお、かかる孔開けや、座刳りは、構造材40における木部が比較的新しい場合には、必要と判断される程度に対応した適宜の孔開けや座刳りをなすようにして構造材40の増設や新規設置や、構造材40相互の補強をなすようにすればよいが、増設や新設相手とされる構造材40が古い家屋等の改修や補強対象とされる構造材40が古い家屋の補強工事等にあっては、前記各孔開けと、座刳りとを当該ボルト受け金物10の備え付け対象構造材40に対して施す。   In addition, when the wood part in the structural material 40 is relatively new, such drilling or sitting down is performed by appropriately drilling or sitting down corresponding to the degree judged to be necessary. It is only necessary to add or newly install or reinforce the structural material 40. However, the structural material 40 to be added or newly installed is a modification of an old house or the structural material 40 to be reinforced is an old house. In the reinforcement work or the like, the above-described perforation and countersinking are performed on the structural material 40 to be provided with the bolt receiving hardware 10.

かかる必要な前施工等を適宜施すと共に、構造材40に対して当該構造材40における雄ねじ12bのねじ先12b’から当該ボルト受け金物10を前記角形断面をなす凹部13に密に嵌り合うビットなどのアタッチメントを備えたインパクトドライバーでねじ入れて、このボルト受け金物10における頭部11の頂面11aがねじ入れ構造材40の面と面一になるまでねじ入れる。   Such necessary pre-construction is appropriately performed, and a bit that closely fits the bolt receiving object 10 from the screw tip 12b ′ of the male screw 12b in the structural material 40 to the concave portion 13 having the square cross section, etc. Then, it is screwed in with an impact driver equipped with the attachment until the top surface 11a of the head 11 of the bolt receiving metal 10 is flush with the surface of the screw-in structure 40.

なお、このボルト受け金物10の構造材40に対するねじ入れに際して、必要に応じて前もって備えられる前記各孔や座刳り凹部40a等が当該構造材40の割れ出し等の不具合を効果的に防ぐと共に当該ボルト受け金物10に備えられている前記頭部11の座面11bに備えられている突条15が当該構造材40の木部を適宜削り出して、構造材40に対する当該ボルト受け金物10の備え付けがより円滑にかつ確実になされる。   In addition, when the bolt receiving hardware 10 is screwed into the structural material 40, the holes, the countersunk recesses 40a, and the like that are provided in advance as needed effectively prevent problems such as cracking of the structural material 40 and the like. The protrusion 15 provided on the seating surface 11b of the head 11 provided in the bolt receiver 10 cuts out the wood portion of the structural material 40 as appropriate, and the bolt receiver 10 is attached to the structural material 40. Is made smoother and more reliable.

更に、必要に応じて、図8に示されるように、この構造材40に備え付けられたボルト受け金物10における前記木ねじ挿通孔16から適宜当該構造材40に対して木ねじ30をねじ入れて適宜の工具、例えば、前記インパクトドライバー等を用いてねじ入れて当該ボルト受け金物10の引き抜き耐力を補強する。例えば、当該木ねじ30を四角頭付き木ねじ30として、この木ねじ30を四角形のビットを取り付けたインパクトドライバー等で適宜構造材40にねじ入れて当該ボルト受け金物10の引き抜き耐力を補強する。   Furthermore, if necessary, as shown in FIG. 8, a wood screw 30 is appropriately screwed into the structural material 40 from the wood screw insertion hole 16 in the bolt receiver 10 provided in the structural material 40 as appropriate. Screws are inserted using a tool such as the impact driver to reinforce the pulling strength of the bolt receiver 10. For example, the wood screw 30 is used as a square head wood screw 30 and the wood screw 30 is appropriately screwed into the structural member 40 with an impact driver or the like to which a square bit is attached to reinforce the pulling strength of the bolt receiver 10.

このボルト受け金物10の構造材40に対する備え付け状態の補強は、このボルト受け金物10に対して要請される引き抜き耐力等によって適宜施される。この図示例にあっては、前記の各木ねじ挿通孔16に対して、例えば、直径が5mm前後の軸部30bを有する70mm〜80mmの木ねじ30をねじ入れて、当該ボルト受け金物10の引き抜き耐力を補強してある。かかる木ねじ30による補強は、当該ボルト受け金物10の雄ねじ12bのみで要請される引き抜き耐力を有しない場合であっても、この木ねじ30による補強によって要請される引き抜き耐力を任意に都合良く補強し得ると共に、当該補強の木ねじ30相互が近づきすぎることに伴う構造材40のねじ込み木部の損傷による引き抜き耐力の低下を避ける点等から、概ね2〜4個の木ねじ挿通孔16を設け、これに木ねじ30をねじ入れることによって補強するようにしてある。   Reinforcement of the mounting state of the bolt receiver 10 with respect to the structural member 40 is appropriately performed according to a pulling strength required for the bolt receiver 10 and the like. In this illustrated example, for example, a 70 mm to 80 mm wood screw 30 having a shaft portion 30b having a diameter of about 5 mm is screwed into each wood screw insertion hole 16, and the pulling strength of the bolt bracket 10 is pulled out. Is reinforced. The reinforcement by the wood screw 30 can arbitrarily reinforce the drawing strength required by the reinforcement by the wood screw 30 even when the pulling strength required only by the male screw 12b of the bolt receiver 10 is not provided. In addition, from the viewpoint of avoiding a decrease in pulling strength due to damage of the screwed wood portion of the structural member 40 caused by the reinforcement wood screws 30 being too close to each other, approximately 2 to 4 wood screw insertion holes 16 are provided, and the wood screws are provided in the holes. 30 is reinforced by screwing in.

なお、この補強に用いられる木ねじ30は、その頭部30aがボルト受け金物10の木ねじ挿通孔16の大きい孔部16a内に納まって当該頭部30aの頂面11aから外方にはみ出ない状態で、当該頭部30aの座面11bを当該孔部16aの底面16cに接して当該ボルト受け金物10を構造材40に対して止着し得る木ねじ30を用いることが望ましい。   It should be noted that the wood screw 30 used for reinforcement is in a state where its head portion 30a is housed in the large hole portion 16a of the wood screw insertion hole 16 of the bolt receiver 10 and does not protrude outward from the top surface 11a of the head portion 30a. It is desirable to use the wood screw 30 that can contact the seating surface 11b of the head portion 30a with the bottom surface 16c of the hole portion 16a and fasten the bolt receiving hardware 10 to the structural member 40.

このように一方の構造材40に対して備え付けられたボルト受け金物10における雌ねじ孔14に対して他方の構造材40に備え付けられる引き寄せ金物80を構成する羽子板金物50のボルト70や、ホールダウン金物60のボルト70をねじ入れて、この直交する向きに組み付けられる構造材40相互を引き寄せ状態にして、構造材40相互の接合をより確実なものとする。   In this way, the bolt 70 of the wing sheet metal 50 that constitutes the drawing metal 80 provided to the other structural material 40 with respect to the female screw hole 14 in the bolt metal fitting 10 provided to the one structural material 40, or the hole down hardware. 60 bolts 70 are screwed in, and the structural members 40 assembled in the orthogonal direction are brought close to each other, so that the structural members 40 can be more reliably joined to each other.

また、前記土台41”に直交ように接合されている柱42’側にホールダウン金物60の引き寄せ金具61を当該柱42’に挿通された2本のボルト62、62で当該柱42’に対して定法で止着した。   Further, a pull-down fitting 61 of a hole-down hardware 60 is attached to the pillar 42 'side that is orthogonally joined to the base 41 "with respect to the pillar 42' by two bolts 62 and 62 inserted into the pillar 42 '. It was fixed by the law.

かかる状態で、このホールダウン金物60の引き寄せ金具61に回転自在に備えられている直径12mmのボルト70の先端を前記土台41”に備えられているボルト受け金物10の雌ねじ孔14にねじ入れて、財団法人日本住宅・木材技術センターの「接合金物試験法規格」に示されている「柱端仕口金物の引張試験」に準拠して引張試験を行った。   In this state, the tip of a bolt 70 having a diameter of 12 mm, which is rotatably provided in the pulling metal fitting 61 of the hole-down hardware 60, is screwed into the female screw hole 14 of the bolt receiving hardware 10 provided in the base 41 ″.

Figure 2007205064
Figure 2007205064

この測定データによれば、最大荷重が40kN前後で、極めてばらつきが少なかった。
また、最大荷重時における変位は20mm〜30mmと、ややばらつくが、これは、ボルト受け金物10が土台41”から引き抜けたり、引き寄せ金具61が大きく曲がったり、溶接部が切れたりして、終局状態が様々の態様に分かれたことによる。このことは、同時に、ボルト受け金物10の引き抜き耐力がZマーク金物である引き寄せ金具61の材料強度と拮抗しており、両者の組合せが良好なバランスにあることを意味している。
According to this measurement data, the maximum load was around 40 kN and there was very little variation.
Further, the displacement at the maximum load varies slightly from 20 mm to 30 mm. This is because the bolt bracket 10 is pulled out from the base 41 ″, the pulling fitting 61 is bent greatly, the welded portion is cut, and the like. This is due to the fact that the state is divided into various forms, which means that the pulling strength of the bolt receiving metal 10 is antagonized with the material strength of the pulling metal fitting 61 which is a Z mark hardware, and the combination of both is in a good balance. It means that there is.
