Description

【０００１】
【発明の属する技術分野】
本発明は、木造建築物（住宅・非住宅）に使用される、位置合わせ機能付き大梁小梁の接合構造に関するものである。
【０００２】
【従来の技術】
主として木造住宅の小梁建方において、木製大梁の初期変形により小梁が所定の位置に円滑（設計通り）に設置できず、小梁と大梁との間が離れすぎたり、近づきすぎる場合、大梁と小梁の間にはその補正・矯正のため両梁間を引き寄せたり、押し開いたりする機能が要求される（図４ａ、ｂ、ｃでも後述する）。この場合、一般的には、図５のように柱に支持された木製大梁１と木製小梁２はあり継手４で結合すると共に、木製小梁２の側面と木製大梁１の間を梁受け金物（図示せず）を介して羽子板ボルト５で締め上げ固定することで継手精度を確保する。
【０００３】
現状では、前記図５に示すように木製小梁３を設置し、羽子板ボルト５で締め上げて位置調整するに際し、木製大梁２を引き寄せたり、押し開くためにジャッキや治具を用いるなど多くの労力をかけたり、部材の端部を部分的に削るなど、せっかく精度よく加工（プレカット）された梁部材であるにもかかわらず現場加工を余儀なくされていた。
【０００４】
また図６に示すように、木製柱と木製大梁の取合い部では、事前に複雑な加工を柱・梁に施した位置合わせ機能付き金物が知られている。同図において、柱６の側面に取付金物７が釘などの固定具８にて固着されている。その取付金物７は横断面コ字型で、上端縁に円弧状ガイド１０が形成され、このガイド下端に位置決め溝１１が形成されている。他方、木製小梁１２の端部中間には取付金物７が嵌る凹溝１３が形成されていて、凹溝１３の両側を貫通してガイドピン１４及び釘などの固定具１５を設けるようになされている（凹溝１３は概要的に示したもので、取付金物７の平行な２片の板厚部が嵌るように、２条の溝が平行に開設されることがある）。
【０００５】
したがって、取付金物７に凹溝１３が嵌まるように木製小梁１２を上方から引き下げ操作し、このとき、ガイドピン１４が取付金物７の上端縁の円弧状ガイド１０に沿って滑動し、それに伴って、柱６が木製小梁１２から設定距離よりも離れていれば引き寄せられ、近づきすぎていれば押し拡げられ、最後にガイド下端の位置決め溝１１にガイドピン１４が嵌合することで柱６と木製小梁１２とが所定の間隔に配置される。この位置で取付金物７と木製小梁１２を貫通して釘などの固定具１５を打設することにより、柱６と木製小梁１２が接合される。
【０００６】
他方、建築物が鉄骨構造部材であれば、いわゆるシノといわれる鉄棒を２部材の孔に挿通して部材間の位置合せを行うことはよく知られているが、木造建築の施工の際職人（大工）は、シノなど異業種（鉄骨工）の工具を持ち合わせていないことが多い。
【０００７】
【発明が解決しようとする課題】
図５、図６の従来技術は、木製の大梁小梁の接合や木製柱と木製小梁の接合構造の例であり、これら従来の関連技術には、本発明が目的とする木製大梁と鋼製小梁の位置合わせ機能付き接合構造については開示されおらず、大梁小梁の位置調整になお手間取っているのが現状である。
【０００８】
本発明は、前記の問題点に鑑みて提案されたもので、▲１▼従来の木製小梁を、寸法精度の高い薄板軽量形鋼等による鋼製小梁に変更する。▲２▼その高い精度利用することで、従来現場で多くの労力を掛け、梁部材に追加加工を複雑な加工までして行っていたものを、鋼製小梁による大梁の位置合わせ（補正・矯正）に変え、これにより極めて簡便に位置調整できるようにする。▲３▼前記位置合わせを、高価な特殊技能や高価な特殊工具・治具を用いずにできるようにすることを目的とする。
【０００９】
【課題を解決するための手段】
前記の目的を達成するため、本発明は次のように構成する。
【００１０】
第１の発明は、相対する木製大梁の間に鋼製小梁を納め、木製大梁に設置した小梁用受け金物を介して前記鋼製小梁と木製大梁を、前記小梁用受け金物に設けられた取付孔から打設されるドリルねじ等の固定具にて固着する接合構造において、前記小梁用受け金物と鋼製小梁には、大梁小梁の施工精度が設計値の通りとなることで両孔が合致する位置に同径の調整孔を開設し、前記調整孔は、前記取付孔の直径より大きな直径からなり、両調整孔の位置ずれを、ボルトやねじ等のねじ込み調整部材の差込み回転によるトルクで調整し、これに伴って、大梁小梁が移動し所定位置に合わせ込み補正・矯正可能に構成していることを特徴とするとする。
【００１１】
第２の発明は、第１の発明において、鋼製小梁をボックス形鋼製建材で構成し、鋼製小梁と小梁用受け金物のそれぞれの両側面に開設の前記調整孔に前記ねじ込み調整部材を差込み回転させることでそのトルクにより、大梁小梁同士を補正・矯正可能に構成していることを特徴とするとする。
【００１２】
第３の発明は、第１または第２の発明に記載の調整孔を有する小梁用受け金物を特徴とする。
【００１３】
第４の発明は、第１〜第３の何れかの発明において、小梁用受け金物と鋼製小梁の両調整孔にねじ込むことで所定のトルクを発揮し、大梁小梁同士を移動させ孔ずれを補正・矯正しうるボルトあるいはねじからなるねじ込み調整部材を特徴とするとする。
【００１４】
【作用】
本発明は、鋼製小梁と木製大梁に設けた小梁用受け金物にあらかじめ精度の高い調整孔（先孔）を開設し、その調整孔が重なる部分にボルトやねじからなるねじ込み調整部材を螺入し、そのトルクにより、鋼製小梁と小梁用受け金物を木製大梁に近づきまたは離れる方向に移動させ位置を合わせ込むことで、鋼製小梁と木製大梁の位置関係を補正・矯正し得るので、従来現場で多くの労力を掛け、梁部材に追加加工を複雑な加工までして行っていた接合作業を簡潔な構造により極めて簡便にでき、かつ、高価な特殊技能や高価な特殊工具・治具を用いず位置合わせできる。
【００１５】
【発明の実施の形態】
以下、本発明の実施形態を図１〜図４を参照して説明する。
【００１６】
図１において、下部柱１６の上端に木製大梁１７が設置され、所定の間隔をあけて平行に配置された前記木製大梁１７間にボックス形鋼からなる鋼製小梁１９が納められ、その両端が小梁用受け金物２０と２０ａを介して木製大梁１７に固定される。
【００１７】
図３に示すように小梁用受け金物２０、２０ａは、鋼製小梁１９の端部底面を支持する底板２１と鋼製小梁１９の両側面を外側から支持する両側板２２と背面板２３とから構成され、前方と上方が開放された形状である。背面板２３には複数の取付孔２４が開設されていて、この取付孔２４から釘、ボルト等の固定具２５を木製大梁１７に打設することで、小梁用受け金物２０、２０ａが木製大梁１７に固着されている。
【００１８】
小梁用受け金物２０、２０ａの両側板２２には、複数の取付孔２６が設けられていて、鋼製小梁１９の端部を小梁用受け金物２０、２０ａの内側に収納させた上、取付孔２６からドリルねじなどの固定具２７を鋼製小梁１９の両側面に向けて打設することにより、鋼製小梁１９を小梁用受け金物２０、２０ａに固定でき、この小梁用受け金物２０、２０ａを介して鋼製小梁１９を木製大梁１７に固定できる。
【００１９】
さらに、図において相対する一方の小梁用受け金物（図１の右方の小梁用受け金物２０）の両側板２２には前記取付孔２６とは別に、調整孔２８が開設されている。これに対応してボックス形鋼からなる鋼製小梁１９の両側面１９ａにも、小梁用受け金物２０の調整孔２８と同径の調整孔２９が開設されている。前記調整孔２８と２９は、木製大梁１７と鋼製小梁１９の施工精度が設計値どおりになったとき両孔が合致する位置に開設されている。
【００２０】
また、大梁と小梁に施工誤差（位置ずれ）が生じたときは、図３（ｄ）、（ｅ）に示すように調整孔２８と２９は、大梁側に近づきまたは離れる方向に位置ずれする。この場合、位置ずれした両調整孔２８と２９に図３（ｂ）に示すようなボルトやねじ等のねじ込み調整部材３０を差込み回転させることで、そのトルクにより両調整孔２８と２９が合致するように操作し、それに伴って木製大梁１７を鋼製小梁１９の側に強制的に引き寄せ（図３ｄに示す）、または強制的に押し開いて（図３ｅに示す）、接合部の補正・矯正行う。この状態で、ドリルねじなどの固定具２７で鋼製小梁１９と小梁用受け金物２０を適正に接合するものである。
【００２１】
実施形態の施工工程を説明する。
【００２２】
▲１▼あらかじめ相対する木製大梁１７に小梁用受け金物２０、２０ａを取付けておく。
▲２▼鋼製小梁（ボックス形鋼）１９の左端をまず一方の小梁用受け金物２０ａの内側に嵌合して位置決めし、ドリルねじ等の固定具２７で固定する。
▲３▼つぎに、鋼製小梁１９の右端を小梁用受け金物２０の内側に嵌合する。このとき、鋼製小梁１９と小梁用受け金物２０の調整孔２９と２８のずれが、鋼製小梁１９と木製大梁１７との位置ずれを示すことになる（図３ｄ，ｅ参照）。
【００２３】
▲４▼その位置ずれした状態で、調整孔２８と２９に、とがり先状のボルトあるいはねじからなるねじ込み調整部材３０を差込み回転させ（図３ｄが引き寄せ機能、図３ｅが押し開き機能を示す）、そのトルクにより小梁・大梁相互のずれを補正・矯正し（図４ａ、ｂ、ｃにその作用を模式図で示す）、その後、左端同様、ドリルねじ等の固定具２７を小梁用受け金物２０の取付け孔２６から打設して両部材を固定するもので、これにより大梁小梁を所定の位置に精度よく建方できる。
【００２４】
▲５▼前記の調整作業に際し、ボルトあるいはねじのねじ込み調整部材３０は、回転によりボックス形鋼の鋼製小梁１９や小梁用受け金物２０の鋼板部分を削り取り、調整孔２８、２９が位置ずれしたまま固定具２７を締込み完了するおそれがあるので、この場合を考慮して、位置ずれした両調整孔２８と２９が合致するよう鋼製小梁１９と小梁用受け金物２０に左右方向に力を加えながら、ねじ込み調整部材３０のねじ込み調整を行うのが望ましく、この操作により梁部材を所定の位置に移動させる機能を確実に実現できる。
【００２５】
以上の実施形態で示した各部の構成を適宜設計変更して実施することは、本発明の範囲に含まれる。例えば、図では調整孔２８は、左右の金物のうち一方の小梁用受け金物２０にのみ設けた例を示すが、両側の金物に調整孔２８を設けてもよい。また、鋼製小梁１９は、ボックス形鋼の例を図示したが、これに限らずＣ形鋼、Ｚ形鋼など各種断面形状の形鋼製小梁部材に適用でき、さらに必要に応じて、各種断面の形鋼製小梁の端部に、調整孔を開設するに適した断面形状となるよう別部材を溶接してもよい。さらに、小梁用受け金物２０、２０ａの形状や木製大梁１７への固着手段等も図示のものに限らない。
【００２６】
【発明の効果】
本発明は、鋼製小梁と木製大梁に設けた小梁用受け金物にあらかじめ精度の高い調整孔（先孔）を開設し、その調整孔が重なる部分にボルトやねじからなるねじ込み調整部材を螺入し、その回転により発生するトルクにより、鋼製小梁と小梁用受け金物を木製大梁に近づきまたは離れる方向に移動させ位置を合わせ込むことで、鋼製小梁と木製大梁の位置関係を補正・矯正するものであるから、従来現場で多くの労力を掛け、梁部材に追加加工を複雑な加工までして行っていた接合作業を、極めて簡便、安全かつ円滑にできる。また、高価な特殊技能や高価な特殊工具・治具を用いず位置合わせできる。

BACKGROUND OF THE INVENTION
The present invention relates to a joining structure of a large beam and a small beam having an alignment function used for a wooden building (house / non-house).
[0002]
[Prior art]
Mainly in the construction of small beams in wooden houses, if the small beams cannot be installed smoothly (as designed) due to the initial deformation of the wooden large beams, and if the distance between the small beams and the large beams is too far or too close, Between the beams, a function of drawing or pushing between the beams is required for the correction / correction (also described later in FIGS. 4a, b, and c). In this case, generally, the wooden beam 1 and the wooden beam 2 supported by the pillar as shown in FIG. 5 are connected by a joint 4 and a beam support is provided between the side surface of the wooden beam 2 and the wooden beam 1. The accuracy of the joint is ensured by tightening and fixing with the wing plate bolts 5 through a hardware (not shown).
[0003]
At present, as shown in FIG. 5, the wooden beam 3 is installed, and when the position is adjusted by tightening with the wing plate bolt 5, a jack or a jig is used to pull the wooden beam 2 or push it open. Despite the fact that it is a beam member that has been processed with high precision (pre-cut), such as applying labor or partially cutting the end of the member, it has been forced to perform on-site processing.
[0004]
In addition, as shown in FIG. 6, a hardware with an alignment function in which complicated processing is performed in advance on a pillar / beam at a joint portion between a wooden pillar and a wooden large beam is known. In the figure, a mounting metal 7 is fixed to a side surface of a column 6 with a fixture 8 such as a nail. The fitting 7 has a U-shaped cross section, and an arcuate guide 10 is formed at the upper end edge, and a positioning groove 11 is formed at the lower end of the guide. On the other hand, a concave groove 13 into which the fitting 7 is fitted is formed in the middle of the end portion of the wooden beam 12, and a guide pin 14 and a fixture 15 such as a nail are provided through both sides of the concave groove 13. (The groove 13 is schematically shown, and two grooves may be opened in parallel so that two parallel plate thickness portions of the mounting hardware 7 can be fitted).
[0005]
Therefore, the wooden beam 12 is pulled down from above so that the concave groove 13 fits into the fitting 7, and at this time, the guide pin 14 slides along the arcuate guide 10 at the upper edge of the fitting 7. Along with this, the pillar 6 is drawn if it is farther than the set distance from the wooden beam 12, and if it is too close, it is expanded, and finally the guide pin 14 is fitted into the positioning groove 11 at the lower end of the guide so that the pillar 6 is fitted. 6 and the wooden beam 12 are arranged at a predetermined interval. The pillar 6 and the wooden beam 12 are joined by driving a fixture 15 such as a nail through the mounting hardware 7 and the wooden beam 12 at this position.
[0006]
On the other hand, if the building is a steel structure member, it is well known that the so-called Shino is inserted into the hole of the two members to align the members, but the craftsmen ( Carpenters often do not have tools from other industries (steelworkers) such as Shino.
[0007]
[Problems to be solved by the invention]
The prior arts in FIGS. 5 and 6 are examples of the joining of wooden beam beams and the joining structure of wooden pillars and wooden beam beams. These conventional related techniques include the wooden beam and steel intended by the present invention. There is no disclosure of a joint structure with an alignment function for a small beam, and the current situation is that it still takes time to adjust the position of the small beam.
[0008]
The present invention has been proposed in view of the above-mentioned problems. (1) A conventional wooden beam is changed to a steel beam made of a thin, lightweight steel having high dimensional accuracy. (2) By using the high accuracy, it has been necessary to adjust the position of the large beam using a steel beam (correction / correction) This makes it possible to adjust the position very easily. (3) An object of the present invention is to enable the above-mentioned alignment without using an expensive special skill or an expensive special tool or jig.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, the present invention is configured as follows.
[0010]
A first aspect of the present invention is housed a steel joists between opposing wooden girders, the steel joists and wooden girders through the joists for receiving hardware installed in the wooden girder, the hardware-receiving the small beam In a joint structure that is fixed by a fixing tool such as a drill screw that is driven from a provided mounting hole, the accuracy of construction of the large beam and the small beam is the same as the design value for the small beam receiver and the steel small beam. As a result, an adjustment hole of the same diameter is opened at a position where both holes match, and the adjustment hole has a diameter larger than the diameter of the mounting hole , and the displacement of both adjustment holes can be adjusted by screwing in bolts or screws. It is characterized in that the adjustment is made by the torque due to the insertion rotation of the member, and along with this, the large beam and the small beam move so as to be adjusted to a predetermined position and can be corrected and corrected.
[0011]
According to a second invention, in the first invention, the steel beam is composed of a box-shaped steel building material, and the screw is screwed into the adjustment holes provided on both side surfaces of the steel beam and the beam receiver. The adjustment member is inserted and rotated so that the large beam and the small beam can be corrected and corrected by the torque.
[0012]
The third invention is characterized by a small beam receiver having the adjustment hole according to the first or second invention.
[0013]
According to a fourth invention, in any one of the first to third inventions, a predetermined torque is exerted by screwing into both adjustment holes of the small beam receiver and the steel small beam, and the large beam small beams are moved to each other. It is characterized by a screwing adjustment member made of a bolt or a screw capable of correcting and correcting the hole deviation.
[0014]
[Action]
In the present invention, a high-precision adjustment hole (tip hole) is opened in advance in a beam receiver for a steel beam and a wooden beam, and a screw adjustment member made of a bolt or a screw is provided in a portion where the adjustment hole overlaps. The position of the steel beam and the wooden beam is corrected and corrected by screwing in and moving the steel beam and the beam receiving tool closer to or away from the wooden beam to align the position. Therefore, it is possible to make the joining work, which has been a lot of labor in the field and complicated additional processing to the beam member, by the simple structure, and it is very simple, and expensive special skills and expensive special Alignment is possible without using tools or jigs.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to FIGS.
[0016]
In FIG. 1, a wooden girder 17 is installed at the upper end of a lower column 16, and a steel girder 19 made of box-shaped steel is placed between the wooden girder 17 arranged in parallel at a predetermined interval. Is fixed to the wooden girder 17 via the small beam receiving parts 20 and 20a.
[0017]
As shown in FIG. 3, the beam receivers 20, 20 a include a bottom plate 21 that supports the bottom surface of the end of the steel beam 19, both side plates 22 that support both sides of the steel beam 19 from the outside, and a back plate. 23, with the front and upper sides being open. A plurality of mounting holes 24 are formed in the back plate 23, and a fixture 25 such as a nail or a bolt is driven from the mounting hole 24 to the wooden large beam 17, so that the small beam receivers 20 and 20 a are made of wooden. It is fixed to the girder 17.
[0018]
A plurality of mounting holes 26 are provided on both side plates 22 of the beam receivers 20 and 20a, and the end of the steel beam 19 is stored inside the beam receivers 20 and 20a. The steel beam 19 can be fixed to the beam receivers 20 and 20a by driving a fixing tool 27 such as a drill screw from the mounting hole 26 toward the both side surfaces of the steel beam 19. The steel small beam 19 can be fixed to the wooden girder 17 through the beam receivers 20 and 20a.
[0019]
Further, in addition to the mounting hole 26, an adjustment hole 28 is formed in the both side plates 22 of one of the opposite small beam receivers (the right small beam receiver 20 in FIG. 1). Correspondingly, an adjustment hole 29 having the same diameter as that of the adjustment hole 28 of the small beam receiver 20 is also formed on both side surfaces 19a of the steel beam 19 made of box-shaped steel. The adjustment holes 28 and 29 are opened at positions where the holes match when the construction accuracy of the wooden beam 17 and the steel beam 19 is as designed.
[0020]
Further, when a construction error (displacement) occurs between the large beam and the small beam, the adjustment holes 28 and 29 are displaced in the direction approaching or leaving the large beam as shown in FIGS. 3 (d) and 3 (e). . In this case, the adjustment holes 28 and 29 are matched by the torque by inserting and rotating a screw adjustment member 30 such as a bolt or a screw as shown in FIG. Accordingly, the wooden large beam 17 is forcibly pulled toward the steel beam 19 (shown in FIG. 3d) or forcedly opened (shown in FIG. 3e). Make corrections. In this state, the steel beam 19 and the beam receiver 20 are appropriately joined by the fixture 27 such as a drill screw.
[0021]
The construction process of the embodiment will be described.
[0022]
{Circle around (1)} The small beam receivers 20 and 20a are attached to the opposed wooden large beams 17 in advance.
{Circle around (2)} The left end of the steel beam (box-shaped steel) 19 is first fitted and positioned inside one of the beam supports 20a, and fixed with a fixture 27 such as a drill screw.
(3) Next, the right end of the steel beam 19 is fitted inside the beam receiver 20. At this time, the shift between the adjustment holes 29 and 28 of the steel beam 19 and the beam receiver 20 indicates a positional shift between the steel beam 19 and the wooden beam 17 (see FIGS. 3d and e). .
[0023]
(4) With the position shifted, the screw adjustment member 30 made of a pointed bolt or screw is inserted into the adjustment holes 28 and 29 and rotated (FIG. 3d shows the pulling function and FIG. 3e shows the push-opening function). Then, the torque corrects and corrects the misalignment between the small beam and the large beam (the operation is schematically shown in FIGS. 4a, 4b, and 4c), and then, like the left end, the fixture 27 such as a drill screw is received for the small beam. Both members are fixed by driving from the mounting hole 26 of the hardware 20, whereby the large beam and the small beam can be accurately erected at a predetermined position.
[0024]
(5) In the above adjustment work, the screw or screw adjusting member 30 is rotated to scrape off the steel plate portion 19 of the box-shaped steel or the steel beam part 20 for the small beam, and the adjustment holes 28 and 29 are positioned. Since there is a possibility that the fixing device 27 may be tightened with being displaced, in consideration of this case, the steel beam 19 and the beam receiving device 20 are moved to the left and right so that the two adjusted holes 28 and 29 are aligned. It is desirable to perform the screwing adjustment of the screwing adjusting member 30 while applying a force in the direction, and this function can reliably realize the function of moving the beam member to a predetermined position.
[0025]
It is within the scope of the present invention to appropriately change the design of the components shown in the above embodiments. For example, in the drawing, the adjustment hole 28 is provided only in one of the left and right metal fittings 20, but the adjustment hole 28 may be provided in both hardware. The steel beam 19 is illustrated as an example of a box-shaped steel, but is not limited to this, and can be applied to a steel beam member having various cross-sectional shapes such as C-shaped steel and Z-shaped steel. Further, another member may be welded to end portions of the steel beam having various cross sections so as to have a cross sectional shape suitable for opening the adjustment hole. Further, the shape of the small beam receivers 20 and 20a and the fixing means to the wooden large beam 17 are not limited to those shown in the drawing.
[0026]
【The invention's effect】
In the present invention, a high-precision adjustment hole (tip hole) is opened in advance in a beam receiver for a steel beam and a wooden beam, and a screw adjustment member made of a bolt or a screw is provided in a portion where the adjustment hole overlaps. The positional relationship between the steel beam and the wooden beam is adjusted by moving the steel beam and the beam receiving tool closer to or away from the wooden beam by the torque generated by the screwing and rotation. Therefore, it is possible to make the joining work, which has been a lot of labor in the field and complicated additional processing to the beam member, extremely simple, safe and smooth. In addition, alignment is possible without using expensive special skills or expensive special tools or jigs.
