Description

本発明は、地震時の繰り返し揺れを受けても吊り金具の変形を防止することができる吊り金具用補強金具に関するものである。   The present invention relates to a reinforcing metal fitting for a hanging metal fitting that can prevent the deformation of the hanging metal fitting even when subjected to repeated shaking during an earthquake.

当出願人は、特許文献１に記載の如く、形鋼に装着した吊り金具が、地震等の振動でも外れないように装着する吊り金具用耐震補助具を先に提案している。この補助具は吊りボルト支持用の吊り金具に装着するもので、この補助具を装着する吊り金具は形鋼フランジの水平突起部に係止する略コ字状の開口部と、この開口部内の水平突起部を下から締め付け固定する締付ボルトとを有するタイプの吊り金具に装着するものである。   As described in Patent Document 1, the applicant of the present application has previously proposed a seismic auxiliary tool for a hanging metal fitting that is attached so that the hanging metal fitting attached to the shape steel is not detached even by vibration such as an earthquake. This auxiliary tool is attached to a hanging bracket for supporting a suspension bolt. The hanging metal fitting to which this auxiliary tool is attached has an approximately U-shaped opening that is engaged with the horizontal protrusion of the shape steel flange, and the inside of this opening. It is attached to a hanging metal fitting of a type having a fastening bolt for fastening the horizontal protrusion from below.

特許文献１の補助具の構成は、吊り金具の側面に係止する平面略Ｕ字形状を成し吊り金具の開口方向に延長された係止杆体と、形鋼に連結する固定板体とを備えたものである。この補助具を吊り金具に装着することにより、地震等で、吊り金具の締付ボルトが緩んだとしても、補助金具が吊り金具を支持しているので、吊り金具の脱落を防止することができる。   The structure of the auxiliary tool of Patent Document 1 includes a locking housing that has a substantially U-shaped planar shape that is locked to the side surface of the hanging bracket and that extends in the opening direction of the hanging bracket, and a fixed plate body that is connected to the shape steel. It is provided. By attaching this auxiliary tool to the hanging bracket, even if the fastening bolt of the hanging bracket is loosened due to an earthquake or the like, the auxiliary bracket supports the hanging bracket, so that the hanging bracket can be prevented from falling off. .

また、特許文献２に、羽根を備えたタイプの吊り金具を補強する補助具が記載されている。この羽根は、吊り金具の左右側面に一対備えられており、形鋼のフランジに当接させることで、吊り金具に対する左右への支持強度を高める効果がある。特許文献２の補助具では、このような羽根を備えた吊り金具を補強する手段として、前記特許文献１にて使用している平面略Ｕ字形状の係止杆体に替えて長ボルトを使用したものである。   Further, Patent Document 2 describes an auxiliary tool that reinforces a hanging metal fitting having a blade type. A pair of the blades is provided on the left and right side surfaces of the suspension fitting, and has an effect of increasing the left and right support strength with respect to the suspension fitting by being brought into contact with the flange of the shape steel. In the auxiliary tool of Patent Document 2, a long bolt is used as a means for reinforcing the hanging metal fitting provided with such blades in place of the flat U-shaped locking housing used in Patent Document 1. Is.

特許第２７４７６６７号公報Japanese Patent No. 2747667 特開２０１１-１６３０７８号公報JP 2011-163078 A

特許文献１や特許文献２に記載の補助金具によると、いずれも、係止杆体や長ボルトの長手方向に沿った強化が可能になり、吊り金具の開口部から形鋼のフランジが外れる方向への吊り金具の移動を防止することはできる。ところが、先の東日本大震災により、これら当初の予想に反する方向に思わぬ脆弱性があることが判明した。   According to the auxiliary metal fittings described in Patent Document 1 and Patent Document 2, it is possible to reinforce along the longitudinal direction of the locking housing and the long bolt, and in the direction in which the flange of the shape steel is removed from the opening of the hanging metal fitting. Can be prevented from moving. However, the Great East Japan Earthquake revealed that there were unexpected vulnerabilities in a direction contrary to these initial expectations.

すなわち、吊り金具の中でも、特許文献２に記載されている羽根を備えたタイプでは、形鋼のフランジに当接する羽根を左右側面に備えているので、この左右方向への支持強度は特に補強しなくても十分な耐久性があると思われていた。ところが、この羽根を備えたタイプの吊り金具に従来の補助金具を装着したものを震災後に確認すると、この羽根に変形が生じ、フランジと羽根との間に隙間が開いているものが確認されている。これは、羽根を備えたタイプの吊り金具に対し、左右の羽根方向に予想を超えた振動や荷重を受けたことにより、羽根に変形が生じたものである。このように羽根に変形が生じ、フランジとの当接面に隙間が生じている吊り金具は、既にフランジに対する締め付け保持力が完全に失われており、更に余震等が加わると簡単に外れてしまう危険性がある。   That is, among the hanging metal fittings, the type provided with the blades described in Patent Document 2 has blades that contact the flange of the shape steel on the left and right side surfaces, so that the support strength in the left-right direction is particularly reinforced. It was thought that it was durable enough without it. However, when the type of suspension fitting with this blade equipped with a conventional auxiliary fitting was confirmed after the earthquake, it was confirmed that the blade was deformed and there was a gap between the flange and the blade. ing. This is because the blades are deformed by receiving unexpected vibrations and loads in the left and right blade directions with respect to the type of suspension metal fitting provided with the blades. In this way, the suspension fittings in which the blades are deformed and a gap is generated on the contact surface with the flange have already completely lost the tightening holding force against the flange, and can easily be removed when an aftershock or the like is applied. There is a risk.

そこで、本発明は上述の課題を解消すべく創出されたもので、羽根を有するタイプの吊り金具に装着することで、吊り金具の左右方向に加わる荷重や振動に対する耐久性を強化することができる吊り金具用補強金具の提供を目的とするものである。   Therefore, the present invention has been created to solve the above-mentioned problems, and by mounting on a suspension fitting having a blade type, durability against load and vibration applied in the left-right direction of the suspension fitting can be enhanced. The purpose is to provide a reinforcing metal fitting for a hanging metal fitting.

The fixed plate body 3 is a member that locks the leading end of the connecting housing 1 to the construction material P. An insertion hole 3 </ b> A for inserting the open end portion of the connecting housing 1 is opened in the fixed plate body 3. Further, a fixing nut 1A is screwed to the tip of the connecting casing 1 inserted through the insertion hole 3A so that the connecting casing 1 and the fixing plate 3 are connected. Then, when the overlapping portion 2A is tightened with the connecting housing 1, the support piece 2B is pressure-bonded to the end of the horizontal protrusion P1, and the position of the connecting housing 1 is fixed.

図示の固定板体３は、挿通孔３Ａと係止片３Ｂとを備えている（図４参照）。挿通孔３Ａは、連結杆体１の開放端部を挿通するもので、この開放端部に固定ナット１Ａをねじ止めして固定板体３に連結する（図２参照）。また、係止片３Ｂは、造営材Ｐの垂直面Ｐ２に固定板体３を当接した状態で、この垂直面Ｐ２の上端に係止するように屈曲形成されたものである。図示例の固定板体３は、造営材ＰとしてＬ形鋼を利用したときに好適であるが、この固定板体３の形状を変えてＨ形鋼の水平突起部Ｐ１に係止するように構成することも可能である（図示せず）。   The illustrated fixing plate 3 includes an insertion hole 3A and a locking piece 3B (see FIG. 4). The insertion hole 3A is inserted through the open end of the connecting housing 1, and a fixing nut 1A is screwed to the open end to connect to the fixed plate 3 (see FIG. 2). The locking piece 3B is formed to be bent so as to be locked to the upper end of the vertical surface P2 in a state where the fixed plate 3 is in contact with the vertical surface P2 of the construction material P. The fixed plate body 3 in the illustrated example is suitable when L-shaped steel is used as the construction material P, but the shape of the fixed plate body 3 is changed so as to be locked to the horizontal protrusion P1 of H-shaped steel. It is also possible to configure (not shown).

図５乃至図７に示す支持体２は、羽根１４上の水平突起部Ｐ１に上から重ねる重合片２Ｄを設けたものである（図５参照）。そして、この重合片２Ｄの一端部から下方に向けて左右一対の支持片２Ｂが屈曲延長されている。この支持片２Ｂは、図２の実施例と同様に、水平突起部Ｐ１の端部に当接せしめると共に連結杆体１を貫通せしめる貫通孔２Ｃが形成されたものである。更に、重合片２Ｄの他端部から上方に向けて左右一対の嵌合片２Ｅが屈曲延長されている（図７参照）。この嵌合片２Ｅは、圧着部１２の左右側面に嵌合するように形成されたものである（図６参照）。そして、重合片２Ｄを水平突起部Ｐ１上に重合すると、支持片２Ｂを貫通する連結杆体１が羽根１４の下面に固定されるように設けたものである。   The support body 2 shown in FIGS. 5 to 7 is provided with a superposed piece 2D that overlaps the horizontal protrusion P1 on the blade 14 from above (see FIG. 5).
