Description

本発明は、トラス骨組部材、より詳細には、体育館、大型展示場、公共施設等の大空間を有するトラスドーム等の建築物を構築するための立体トラス、ラチス梁等に用いる部材で、意匠的に優れた木製トラス材を用いたトラス骨組部材に関するものである   The present invention relates to a truss frame member, more specifically, a member used for a three-dimensional truss, a lattice beam or the like for constructing a building such as a truss dome having a large space such as a gymnasium, a large exhibition hall, or a public facility. Related to truss frame members using wooden truss

トラス骨組部材として、スチールパイプの両端を潰して連結用ボルト孔を形成したものがある。このトラス骨組部材は、複数、端部を重ねて連結用ボルト孔にボルトを通して連結していくものである。   There is a truss frame member in which both ends of a steel pipe are crushed to form connecting bolt holes. In this truss frame member, a plurality of ends are overlapped and connected to a connecting bolt hole through a bolt.

このスチールパイプのトラス骨組部材の場合、スチールパイプがむき出しになっているため、外観美がないだけでなく、温もりを感ずることができず、むしろ寒さを覚えてしまうものである。   In the case of this steel pipe truss frame member, since the steel pipe is exposed, not only is there no appearance beauty, but the warmth cannot be felt, but rather the cold is remembered.

そこで、本願出願人は、温もりのある外観で見た目がよく、しかも製造容易でトラス材の破損が起こりにくい木製トラス骨組部材として、木製トラス材４１の両端面中央部に、棒材４９を充填したパイプ４４を嵌入し、パイプ４４及びトラス材４１に貫設したピン孔４３、５０同士を合わせ、そこにドラフトピン４５を打ち込んでパイプ４４をトラス材４１内に固定し、パイプ４４のトラス材４１端面からの露出部において、グローブ５２に対する固定ボルト４７を保持可能にして成る木製トラス骨組部材を提唱した（特開２００５−１７１４９８号、図７）   Therefore, the applicant of the present application filled a bar 49 in the center of both ends of the wooden truss 41 as a wooden truss frame member that looks good with a warm appearance and is easy to manufacture and is less likely to damage the truss. The pipe 44 is inserted, the pin holes 43 and 50 penetrating the pipe 44 and the truss member 41 are aligned with each other, and the draft pin 45 is driven therein to fix the pipe 44 in the truss member 41. A wooden truss frame member that can hold the fixing bolt 47 to the globe 52 at the exposed portion from the end face has been proposed (Japanese Patent Laid-Open No. 2005-171498, FIG. 7).

この木製トラス骨組部材の場合は、上記のとおり、予めトラス材４１の側面にドリフトピン４５を打ち込むためのピン孔４３が複数、交互に打ち込み方向を変えて穿設され、また、パイプ４４の側面には、ドリフトピン４５を打ち込むための、棒材４９を通して貫通するピン孔５０が、予め貫設される。   In the case of this wooden truss frame member, as described above, a plurality of pin holes 43 for driving the drift pins 45 into the side surface of the truss member 41 are previously drilled by alternately changing the driving direction. In this case, a pin hole 50 penetrating through the bar 49 for driving the drift pin 45 is provided in advance.

この場合、ピン孔４３とピン孔５０は、当然のことながらパイプ４４の挿入孔４２内への嵌入時に互いに合致するように設計されて穿設されるが、実際には誤差があり、それが集積されると更に大きな誤差となり、ドリフトピン４５の打込みに支障を来たす。また、温度や湿度の変化によって木材の含水率も変わり、伸縮したり反ったりするために、ピン孔４３とピン孔５０とが合致しなくなることも少なくない。そこで、ピン孔４３とピン孔５０とを大きめに穿孔しておくことも考えられるが、そのようにした場合は、骨組みのガタつき発生の原因となる。   In this case, the pin hole 43 and the pin hole 50 are naturally designed and drilled so as to match each other when the pipe 44 is inserted into the insertion hole 42. If they are integrated, a larger error occurs, which hinders the driving of the drift pin 45. Further, the moisture content of the wood also changes due to changes in temperature and humidity, and the pin holes 43 and the pin holes 50 often do not match because they expand and contract or warp. Therefore, it is conceivable that the pin hole 43 and the pin hole 50 are perforated larger, but in such a case, it causes a looseness of the skeleton.

Then, one of the bolts is fixed to the end face of the truss member by being screwed into a female screw hole formed in the rod-shaped metal object, and the other bolt is screwed into the globe joint, whereby the truss member is attached to the globe. A plurality of pin holes for penetrating drift pins into the truss member, and a pin hole corresponding to the pin hole is formed in the rod-shaped hardware. The pin hole of the rod-shaped hardware formed is larger than the pin hole of the truss member.

前記接合金具は、前記棒状金物にネジ付けられる固定ボルトと、前記固定ボルトと一体化されていて前記トラス材の端面に当接するベースと、前記ベースに固定される筒状キャップと、ヘッドが前記キャップに係止されて前記キャップに回転自在に保持されるグローブジョイントネジ込み用の接合ボルトと、前記接合ボルトを遊挿する締込みスリーブとから成り、前記締込みスリーブには、前記接合ボルトに設置したピンを係止する長孔が形成されるものであることが好ましい。   The joint fitting includes a fixing bolt that is screwed to the rod-shaped hardware, a base that is integrated with the fixing bolt and abuts against an end surface of the truss member, a cylindrical cap that is fixed to the base, and a head that includes the head A joint bolt for screwing a glove joint screwed to the cap and rotatably held by the cap, and a tightening sleeve for loosely inserting the joint bolt, the tightening sleeve includes the joint bolt It is preferable that a long hole for locking the installed pin is formed.

好ましくは、前記棒状金物は丸棒状であり、前記棒状金物固定用のボルトと、前記ベースと、前記キャップとが溶接により一体化され、また、前記各ピン孔は、交互に方向を違えて形成される。更に好ましくは、前記ドリフトピンに、それと前記棒状金物及び前記トラス材との隙間に接着剤を注入するための接着剤充填路が形成される。   Preferably, the bar-shaped hardware is a round bar shape, the bolt for fixing the bar-shaped hardware, the base, and the cap are integrated by welding, and the pin holes are alternately formed in different directions. Is done. More preferably, an adhesive filling path for injecting an adhesive into a gap between the drift pin and the rod-shaped hardware and the truss member is formed in the drift pin.

本発明に係るトラス骨組部材は上記のとおりであり、殊に、棒状金物のピン孔がトラス材のピン孔よりも大きいため、ドリフトピンの打ち込みが容易で、接合金具のネジ付けに伴なって棒状金物が引き出されてガタつくことがない。従って、温度や湿度の変化等によって木製トラス材に誤差が生じたとしても、グローブジョイントに対し緩みを生ずることなく緊締することが可能で、増し締めすることもでき、骨組みにガタつきを生ずることがないという効果がある。   The truss frame member according to the present invention is as described above, and in particular, since the pin hole of the rod-shaped hardware is larger than the pin hole of the truss member, it is easy to drive in the drift pin, and accompanying the screwing of the joining metal fitting The rod-shaped hardware is pulled out and will not rattle. Therefore, even if an error occurs in the wooden truss due to changes in temperature or humidity, it can be tightened without loosening the glove joint, it can be tightened, and the frame will be loose. There is an effect that there is no.

本発明の好ましい実施の形態を添付図面に依拠して説明する。図１に示される本発明に係るトラス骨組部材は、トラス材１と、トラス材１に挿入される棒状金物２と、棒状金物２に連結されることによってトラス材１の端面に固定されると共に、グローブジョイント４に連結される接合金具３とから成る。   Preferred embodiments of the present invention will be described with reference to the accompanying drawings. The truss frame member according to the present invention shown in FIG. 1 is fixed to the end surface of the truss member 1 by being connected to the truss member 1, the rod-like metal member 2 inserted into the truss member 1, and the rod-like member 2. , And a joint fitting 3 connected to the globe joint 4.

トラス材１は木製であって、通常四角柱であるが、他の形状、例えば、円柱、六角柱等であってもよい。トラス材１の両端面中央部には、棒状金物２をその長さ方向に嵌入するための挿入孔５が穿設される。挿入孔５の深さは、棒状金物２の長さに対応するものとされる。   The truss member 1 is made of wood and is usually a quadrangular prism, but may have other shapes such as a cylinder, a hexagonal column, or the like. An insertion hole 5 for inserting the rod-shaped hardware 2 in the length direction is formed in the center of both end surfaces of the truss member 1. The depth of the insertion hole 5 corresponds to the length of the rod-shaped hardware 2.

棒状金物２は、通例鋼材、アルミニウム材その他の金属製棒材で、断面円形の場合が多いが、それに限られる訳ではない。トラス材１には、その長さ方向と直角の方向に、一側から他側に抜けるピン孔６が複数貫設される。通例、ピン孔６は、交互に方向を変えて（９０度ずらして）形成される。また、棒状金物２にも、その挿入孔２への挿入時にピン孔６に対応するように、交互に方向を変えて複数のピン孔７が貫設される（図２参照）。ピン孔７は、ピン孔６よりも大きめに形成される。棒状金物２を挿入孔５へ挿入してそこに固定する際には、ピン孔６からピン孔７を貫いてドリフトピン８が打ち込まれる。   The rod-shaped hardware 2 is usually a steel bar, an aluminum bar or other metal bar, and is often circular in cross section, but is not limited thereto. The truss member 1 is provided with a plurality of pin holes 6 extending from one side to the other side in a direction perpendicular to the length direction. Usually, the pin holes 6 are formed by alternately changing the direction (shifted by 90 degrees). Also, a plurality of pin holes 7 are penetratingly formed in the rod-shaped hardware 2 so as to correspond to the pin holes 6 when inserted into the insertion holes 2 (see FIG. 2). The pin hole 7 is formed larger than the pin hole 6. When the rod-shaped hardware 2 is inserted into the insertion hole 5 and fixed thereto, the drift pin 8 is driven from the pin hole 6 through the pin hole 7.

通例、ドリフトピン８には、その一端面中心から長さ方向に延びる接着剤充填路１８が穿設され、その途中及び／又は末端に、横方向に分岐してピン外周面に開口する分岐路１８ａが形成される。そして、上記のようにドリフトピン８を打ち込んだ後、接着剤充填路１８に接着剤が注入される。注入された接着剤は、分岐路１８ａからドリフトピン８の周面と周囲部材との隙間に浸出し、ドリフトピン８と棒状金物２、並びに、ドリフトピン８とトラス材１とが接着され、強固に一体化される。   In general, the drift pin 8 is provided with an adhesive filling path 18 extending in the length direction from the center of one end surface thereof, and branching path that branches in the lateral direction and opens to the outer peripheral surface of the pin in the middle and / or the end thereof. 18a is formed. Then, after the drift pin 8 is driven as described above, the adhesive is injected into the adhesive filling path 18. The injected adhesive is leached from the branch path 18a into the gap between the peripheral surface of the drift pin 8 and the surrounding member, and the drift pin 8 and the rod-shaped hardware 2 and the drift pin 8 and the truss member 1 are bonded to each other. Integrated into

棒状金物２の一端面（両端面の場合もある）にはメネジ孔９が形成され、そこに接合金具３の固定ボルト１０がネジ込まれる。   A female screw hole 9 is formed in one end surface (in some cases, both end surfaces) of the rod-shaped hardware 2, and a fixing bolt 10 of the joint fitting 3 is screwed into the female screw hole 9.

接合金具３は、固定ボルト１０と一体化されていてトラス材１の端面に当接するベース１１と、ベース１１に固定されるキャップ１２と、ヘッドがキャップ１２に係止されていて締込みスリーブ１３を介して回転させられる接合ボルト１４とから成る。   The joining metal fitting 3 includes a base 11 that is integrated with the fixing bolt 10 and abuts against an end surface of the truss member 1, a cap 12 that is fixed to the base 11, a head that is locked to the cap 12, and a fastening sleeve 13. And a joining bolt 14 that is rotated via the screw.

固定ボルト１０はそのネジ杆部を突出させた状態でベース１１に溶接され、キャップ１２は固定ボルト１０のヘッドに被せるようにしてベース１１に溶接され、かくしてこれら３部品が一体化される。   The fixing bolt 10 is welded to the base 11 with its threaded portion protruding, and the cap 12 is welded to the base 11 so as to cover the head of the fixing bolt 10, thus integrating these three components.

接合ボルト１４はそのヘッドがキャップ１２内において係止され、そのネジ杆部がキャップ１２から突出した状態にて、回転自在に保持される。接合ボルト１４の突出部には締込みスリーブ１３が、回転自在に被装される。締込みスリーブ１３には、接合ボルト１４の軸方向に長い長孔１５が形成され、この長孔１５を通して接合ボルト１４のネジ杆部にピン１６が、若干長孔１５から飛び出るようにして固定される。   The joining bolt 14 has its head locked in the cap 12 and is rotatably held in a state where its threaded portion protrudes from the cap 12. A tightening sleeve 13 is rotatably mounted on the protruding portion of the joining bolt 14. The fastening sleeve 13 is formed with a long hole 15 that is long in the axial direction of the joining bolt 14, and the pin 16 is fixed to the threaded portion of the joining bolt 14 through the long hole 15 so as to slightly protrude from the elongated hole 15. The

本発明に係るトラス骨組部材を組み立てるには、先ず、挿入孔５に棒状金物２を、ピン孔６とピン孔７を対応させるようにして挿入し、ピン孔６からドリフトピン８を打ち込む。ピン孔７はピン孔６よりも大きく穿孔されるため、この打ち込み作業に際しての孔合わせは容易で、当該作業を難なく行なうことができる。このようにピン孔７がピン孔６よりも大きい場合には、ドリフトピン８の打ち込み後においても、棒状金物２は挿入孔５内において若干移動可能となる。   In order to assemble the truss frame member according to the present invention, first, the rod-shaped hardware 2 is inserted into the insertion hole 5 so that the pin hole 6 and the pin hole 7 correspond to each other, and the drift pin 8 is driven from the pin hole 6. Since the pin hole 7 is drilled larger than the pin hole 6, the hole alignment at the time of this driving operation is easy and the operation can be performed without difficulty. As described above, when the pin hole 7 is larger than the pin hole 6, the rod-shaped hardware 2 can be slightly moved in the insertion hole 5 even after the drift pin 8 is driven.

次いで、キャップ３を持って固定ボルト１０を棒状金物２のメネジ孔９にネジ込んでいく。やがてベース１１が、回転しながらトラス材１の端面に軽く摺接するので、更に強くネジ込んでいくと、棒状金物２が移動可能分引き上げられて強く締まり、ベース１１がトラス材１の端面に強く当接し、キャップ３の回転が困難となる。そこで、ベース１１をネジ１７やビスにより、トラス材１の端面に完全固定する。   Next, holding the cap 3, the fixing bolt 10 is screwed into the female screw hole 9 of the rod-shaped hardware 2. Eventually, the base 11 slidably contacts the end surface of the truss member 1 while rotating. Therefore, when the screw 11 is further tightened, the bar-shaped hardware 2 is pulled up by a movable amount and tightened strongly. The cap 3 is difficult to rotate. Therefore, the base 11 is completely fixed to the end surface of the truss member 1 with screws 17 and screws.

上記のようにして組み立てたトラス骨組部材は、従来のものと同様に、１つのグローブジョイント４に複数組み付け、所望の立体トラス、ラチス梁等を組み上げていく（図４、図５参照）。グローブジョイント４への組み付けに当っては、連結ボルト１４の先端をグローブジョイント４の任意のメネジ孔４ａに当てがい、締込みスリーブ１３を回転させる。それにより、締込みスリーブ１３の長孔１５に係合しているピン１６を介して連結ボルト１４が回転させられ、メネジ孔４ａにネジ込まれていく。   As in the conventional case, a plurality of truss frame members assembled as described above are assembled to one glove joint 4 and a desired three-dimensional truss, lattice beam, etc. are assembled (see FIGS. 4 and 5). In assembling to the globe joint 4, the tip of the connecting bolt 14 is applied to an arbitrary female screw hole 4 a of the globe joint 4, and the tightening sleeve 13 is rotated. As a result, the connecting bolt 14 is rotated via the pin 16 engaged with the long hole 15 of the tightening sleeve 13 and screwed into the female screw hole 4a.

骨組みが緩んだ場合にも、同様に締込みスリーブ１３を締め上げていく。かくして、ガタつきのない確固とした立体トラス等が完成する。   When the skeleton is loosened, the tightening sleeve 13 is similarly tightened. Thus, a solid three-dimensional truss without rattling is completed.

この発明をある程度詳細にその最も好ましい実施形態について説明してきたが、この発明の精神と範囲に反することなしに広範に異なる実施形態を構成することができることは明白なので、この発明は添付請求の範囲において限定した以外はその特定の実施形態に制約されるものではない。   Although the present invention has been described in some detail with respect to its most preferred embodiments, it will be apparent that a wide variety of different embodiments can be constructed without departing from the spirit and scope of the invention, the invention being defined by the appended claims. It is not restricted to the specific embodiment other than limiting in.
