本考案は、結合金具及び該結合金具を用いた柱と横材との結合構造に関するも のである。 The present invention relates to a coupling fitting and a coupling structure between a column and a cross member using the coupling fitting. It is.
【０００２】0002
従来、柱と横材との結合に際しては、図５或いは図６に示すような結合金具が 汎用されている。 例えば、図５に示す結合金具の場合は、結合用軸棒ａの後半分が緊締部ｂとな され、該緊締部ｂは、その表面に螺設された雄螺子ｃと丸座金ｄと雄螺子ｃに螺 合可能な雌螺子ｅとからなり、又、前半分には割り溝ｆが穿設された係止片取付 部ｇが設けられ、係止片ｈがその重心を外した位置を支点として、支軸ｉの周り に回動可能に軸着されており、同図（ロ）の破線で示すように、係止片取付部ｇ の割り溝ｆ内に係止片ｈの短尺部分を収容して全体を係止片取付部ｇの軸方向に 合わせた状態（係止片ｈの軸芯と係止片取付部ｇの軸芯とを一致させた状態）で 真っ直ぐにすることが可能であると共に、同図（ハ）に示すように、チャンネル 鋼からなる柱ｊと、この中に嵌入した横桟からなる横材ｋとの結合部において、 重ね合わせ部に設けられた挿通孔ｓに、係止片ｈを挿入し更に横材ｋの空洞部に 位置させると、係止片ｈは自重でその長尺部を下側にしてほぼ直立状態となる。 次いで、僅かにこの結合金具を引き戻してその係止片ｈを重ね合わせ部の内側壁 に当接した状態とし、雄螺子ｃと雌螺子ｅとで緊締するのである。 Conventionally, when joining columns and cross members, joining metal fittings as shown in Fig. 5 or 6 were used. It is commonly used. For example, in the case of the coupling fitting shown in Fig. 5, the rear half of the coupling shaft a becomes the tightening part b. The tightening part b has a male screw c screwed on its surface, a circular washer d and a male screw c screwed together. It consists of a female screw e that can be fitted together, and a locking piece with a split groove f bored in the front half. A portion g is provided, and the locking piece h moves around the support shaft i using the position where the center of gravity is removed as a fulcrum. As shown by the broken line in the same figure (b), the locking piece mounting part g The short part of the locking piece h is accommodated in the split groove f of In the aligned state (the axis of the locking piece h and the axis of the locking piece mounting part g are aligned) It is possible to make the channel straight, as shown in the same figure (c). At the joint between the column j made of steel and the horizontal member k made of a horizontal crosspiece fitted therein, Insert the locking piece h into the insertion hole s provided in the overlapping part, and then insert it into the hollow part of the cross member k. When positioned, the locking piece h becomes approximately upright with its long portion facing downward due to its own weight. Next, pull back this coupling fitting slightly and attach the locking piece h to the inner wall of the overlapping part. , and tighten with male screw c and female screw e.
【０００３】 又、図６に示す結合金具の場合は、結合用軸棒ｐに設けられる係止片取付部と 係止片との構造が、図５に示す従来の結合金具と異なっている。即ち、係止片取 付部ｍに取り付けられる係止片ｎは、係止片取付部ｍを挟んで二枚の係止板ｏ、 ｏ’と、この係止板ｏ、ｏ’の前部及び後部の上縁間に架設された連結板ｑ、ｑ ’とからなっており、係止片ｎを支軸ｉの周りに回動させたとき、この連結板ｑ 、ｑ’が係止片取付部ｍの上縁又は下縁に当たる為に、同図（ロ）に示すように 係止片ｎの軸方向を係止片取付部ｍの軸方向に合わせた状態で、係止片取付部ｍ と係止片ｎとを真っ直ぐにすることが出来ず、傾斜した状態となる。この為、重 ね合わせ部に設けられる挿通孔ｒの孔径Ｄは大きくとっておく必要がある。0003 In addition, in the case of the coupling fitting shown in Fig. 6, the locking piece mounting portion provided on the coupling shaft p and The structure with the locking piece is different from the conventional coupling fitting shown in FIG. That is, the locking piece The locking piece n attached to the attachment part m has two locking plates o, with the locking piece attachment part m in between. o' and connecting plates q, q installed between the front and rear upper edges of this locking plate o, o' ', and when the locking piece n is rotated around the spindle i, this connecting plate q , q' hits the upper or lower edge of the locking piece mounting part m, as shown in the same figure (b). With the axial direction of the locking piece n aligned with the axial direction of the locking piece mounting part m, and the locking piece n cannot be made straight, resulting in an inclined state. For this reason, heavy The hole diameter D of the insertion hole r provided in the mating portion must be set large.
【０００４】0004
ところが、図５に示す結合金具の場合は、係止片ｈが一枚であり、その厚みは 割り溝ｆの幅に制約されるから、結合金具の耐引抜強度は比較的小さなものとな り、満足な結合強度が得られないという問題があった。又、図６に示す結合金具 の場合は、係止片ｎが二枚の係止板ｏ、ｏ’からなり、しかもその厚さを厚くす ることができるので、結合金具の耐引抜強度は比較的大きなものとすることが出 来るが、重ね合わせ部に設けられる挿通孔ｒの孔径Ｄは大きくとらざるを得ず、 従って重ね合わせ部自体の強度が低下するという問題があった。 However, in the case of the coupling fitting shown in Fig. 5, there is only one locking piece h, and its thickness is Since it is limited by the width of the split groove f, the pull-out strength of the coupling fitting is relatively small. Therefore, there was a problem that a satisfactory bond strength could not be obtained. In addition, the coupling fittings shown in Fig. 6 In this case, the locking piece n consists of two locking plates o and o', and the thickness is increased. Therefore, the pull-out strength of the coupling fittings can be relatively high. However, the hole diameter D of the insertion hole r provided in the overlapping part has to be large, Therefore, there was a problem in that the strength of the overlapping portion itself was reduced.
【０００５】 本考案はこのような従来技術の欠点を解消し、結合金具及び該結合金具を用い た柱と横材との結合構造に於いて、結合金具の耐引抜強度及び重ね合わせ部自体 の強度の何れにも悪影響を与えないものを提供することを目的としてなされたも のである。[0005] The present invention solves the drawbacks of the conventional technology and provides a coupling fitting and a method using the coupling fitting. In the joint structure between the column and the horizontal member, the pull-out strength of the joint fittings and the overlapping part itself The purpose of this product is to provide a product that does not adversely affect the strength of the product. It is.
