Description

本発明は、例えば、略正方形断面の柱材の側面に略台形断面の被締結部材を取り付けるための構造材の結合構造に係り、特に、部品点数が少ない簡単な構造で容易に取り付けることができ、且つ、外力によって外れ難く強固な固定状態を得ることができるように工夫したものに関する。   The present invention relates to, for example, a structure for joining structural members for attaching a fastened member having a substantially trapezoidal cross section to a side surface of a column having a substantially square cross section, and in particular, can be easily attached with a simple structure having a small number of parts. And it is related with what was devised so that it might be hard to come off by external force and a firm fixed state could be obtained.

例えば、略正方形断面の柱材の側面に略台形断面の被締結部材を固定させる場合、柱材の側面と該部材に孔を設け、該孔を貫通するボルトとそのボルトに螺合させるナットによって締結・固定させる構成が一般的である。   For example, when fixing a fastened member having a substantially trapezoidal cross section to a side surface of a column material having a substantially square cross section, a hole is provided in the side surface of the column material and the member, and a bolt passing through the hole and a nut screwed into the bolt are used. A configuration that is fastened and fixed is common.

又、図１、図２、図４、図５に示すように、上記被締結部材１１と上記ジョイントピース１９は、上記溝３内において、接合面１７と接合面２０を当接させた状態で、且つ、連結用係合凸部１５と連結用係合凹部２３を係合させた状態で設置されている。 As shown in FIGS. 1, 2, 4, and 5, the fastened member 11 and the joint piece 19 are in a state where the joint surface 17 and the joint surface 20 are in contact with each other in the groove 3. In addition, the coupling engaging projection 15 and the coupling engaging recess 23 are engaged with each other.

上記ジョイントピース１９の雌ねじ部２５には押しねじ２７が螺合されている。上記押しねじ２７を上記雌ねじ部２５に螺合させていくことによりその先端が雌ねじ部２５より突出する。その突出した押しねじ２７の先端によって上記被締結部材１１を付勢・移動させ、それによって、上記被締結部材１１及び上記ジョイントピース１９を相互に離間する方向に付勢・移動させるものである。これにより、上記被締結部材１１の固定用係合凸部１３と上記柱材１の固定用係合凹部５が係合すると共に、上記ジョイントピース１９の固定用係合凸部２１と上記柱材１の固定用係合凹部５が係合し、被締結部材１１と柱材１が強固に締結・固定されることなる。 A push screw 27 is screwed into the female thread portion 25 of the joint piece 19. When the push screw 27 is screwed into the female screw portion 25, the tip thereof protrudes from the female screw portion 25. The to-be-fastened member 11 is urged / moved by the tip of the protruding push screw 27, and thereby the to-be-fastened member 11 and the joint piece 19 are urged / moved in a direction away from each other. As a result, the fixing engaging convex portion 13 of the fastened member 11 and the fixing engaging concave portion 5 of the column member 1 are engaged, and the fixing engaging convex portion 21 of the joint piece 19 and the column member are engaged. 1 fixing engagement recesses 5 are engaged, and the fastened member 11 and the column member 1 are firmly fastened and fixed.

以上の構成を基にその作用を説明する。
まず、柱材１の溝３内に被締結部材１１を設置すると共にジョイントピース１９を設置する。その際、上記被締結部材１１の連結用係合凸部１５と上記ジョイントピース１９の連結用係合凹部２３とを係合させた状態とする。 The operation will be described based on the above configuration.
First, the fastened member 11 is installed in the groove 3 of the column 1 and the joint piece 19 is installed. At that time, the connecting engaging convex portion 15 of the fastened member 11 and the connecting engaging concave portion 23 of the joint piece 19 are engaged.

次に、上記ジョイントピース１９の雌ねじ部２５に押しねじ２７を螺合させていく。押しねじ２７を雌ねじ部２５に螺合させていくことにより、押しねじ２７の先端が雌ねじ部２５より突出していき、それによって、上記被締結部材１１を付勢し、その結果、上記被締結部材１１と上記ジョイントピース１９が相互に離間する方向へと移動することになる。これによって、上記被締結部材１１の固定用係合凸部１３と上記柱材の溝３の固定用係合凹部５が係合すると共に、上記ジョイントピース１９の固定用係合凸部２１と上記溝３の固定用係合凹部５が強固に係合する。   Next, a push screw 27 is screwed into the female screw portion 25 of the joint piece 19. By screwing the push screw 27 into the female screw portion 25, the tip of the push screw 27 protrudes from the female screw portion 25, thereby urging the fastened member 11 and as a result, the fastened member. 11 and the joint piece 19 move in a direction away from each other. As a result, the fixing engaging convex portion 13 of the fastening member 11 and the fixing engaging concave portion 5 of the groove 3 of the column member engage with each other, and the fixing engaging convex portion 21 of the joint piece 19 and the fixing convex portion 21 of the joint piece 19 are engaged. The fixing engaging recess 5 of the groove 3 is firmly engaged.

又、上記ジョイントピース１９は上記押ねじ２７によって付勢されるのに伴い、上記連結用係合凹部２３を介して上記連結用係合凸部１５を中心にして僅かに回転することになり、それによって、上記固定用係合凸部２１と上記固定用係合凹部５がより強固に係合することになる。以上の作用により、上記被締結部材１１は上記柱材１に強固に締結されることになる。 Further, as the joint piece 19 is urged by the push screw 27, the joint piece 19 is slightly rotated around the coupling engagement convex portion 15 via the coupling engagement concave portion 23. Accordingly, the fixing engaging convex portion 21 and the fixing engaging concave portion 5 are more firmly engaged. With the above operation, the fastened member 11 is firmly fastened to the pillar material 1.

以上本実施の形態によると、次のような効果を奏することができる。
まず、少ない部品点数で且つ容易な作業によって、被締結部材１１を柱材１の溝３に取り付けることができる。すなわち、部品点数は、被締結部材１１、ジョイントピース１９、押ねじ２７の３点のみであり、上記被締結部材１１及び上記ジョイントピース１９を柱材１の溝３に挿入し組み合わせた後、上記押ねじ２７を上記ジョイントピースの雌ねじ部２５に螺合し回転させるだけで所望の締結構造を得ることができるからである。
又、取付位置の変更も容易である。すなわち、上記押しねじ２７を緩めるだけで締結力が弱まり、上記被締結部材１１及び上記ジョイントピース１９を上記溝３に沿ってスライドさせることができるからである。
又、強固な締結状態を得られる。すなわち、上記押しねじ２７が回転し上記被締結部材１１の方向へ移動することで上記被締結部材１１と上記ジョイントピース１９を相互に離間する方向へと付勢し、上記被締結部材１１の固定用係合凸部１３と上記溝３の固定用係合凹部５が係合すると共に、上記ジョイントピース１９の固定用係合凸部２１と上記溝３の固定用係合凹部５が強固に係合する構成になっているからである。又、上記ジョイントピース１９が連結用係合凹部２３を介して連結用係合凸部１５を中心にして僅かに回転するため上記ジョイントピース１９の固定用係合凸部２１と上記溝３の固定用係合凹部５の係合がより強固となる構成になっているからである。
又、上記被締結部材１１の接合面１７と上記ジョイントピース１９の接合面２０が上記ジョイントピース１９の移動方向に対して傾斜した方向に設けられているので、上記被締結部材１１に対して溝３方向に押し付ける力が効果的に作用し、その結果上記被締結部材１１を上記溝３に対してより強固に押し付けて、被締結部材１１の溝３側の面を溝３に対して密着させた状態で締結・固定することができ、被締結部材１１の溝３の反対側の面を溝３に対して平行に保つことができる。 As described above, according to the present embodiment, the following effects can be obtained.
First, the fastened member 11 can be attached to the groove 3 of the column member 1 by an easy operation with a small number of parts. That is, the number of parts is only 3 points of the fastened member 11, the joint piece 19, and the set screw 27. After the fastened member 11 and the joint piece 19 are inserted into the groove 3 of the pillar 1 and combined, This is because a desired fastening structure can be obtained simply by screwing the push screw 27 into the female thread portion 25 of the joint piece and rotating it.
Also, the mounting position can be easily changed. That is, simply loosening the push screw 27 weakens the fastening force, and the fastened member 11 and the joint piece 19 can be slid along the groove 3.
Moreover, a firm fastening state can be obtained. That is, when the push screw 27 rotates and moves in the direction of the fastened member 11, the fastened member 11 and the joint piece 19 are biased in a direction away from each other, and the fastened member 11 is fixed. The engaging convex portion 13 and the fixing concave portion 5 for fixing the groove 3 are engaged, and the fixing engaging convex portion 21 for the joint piece 19 and the fixing concave portion 5 for fixing the groove 3 are firmly engaged. This is because they are configured to match. Further, since the joint piece 19 is slightly rotated about the coupling engagement convex portion 15 through the coupling engagement concave portion 23, the fixing engagement convex portion 21 of the joint piece 19 and the groove 3 are fixed. This is because the engagement recess 5 for use is more firmly engaged.
Further, since the joint surface 17 of the member to be fastened 11 and the joint surface 20 of the joint piece 19 are provided in a direction inclined with respect to the moving direction of the joint piece 19, a groove is formed with respect to the member to be fastened 11. A force pressing in three directions effectively acts, and as a result, the member to be fastened 11 is more strongly pressed against the groove 3, and the surface of the member to be fastened 11 on the groove 3 side is brought into close contact with the groove 3. It is possible to fasten and fix in a state where the groove 3 is held, and to keep the surface of the fastened member 11 opposite to the groove 3 parallel to the groove 3.
