Description

本考案は吊り金具用補強金具に関し、詳しくはＨ型鋼等の溝形鋼のフランジに取り付けられる吊り金具の固定を補強する吊り金具用補強金具に関する。   The present invention relates to a reinforcing metal fitting for a hanging metal fitting, and more particularly to a reinforcing metal fitting for a hanging metal fitting that reinforces fixing of a hanging metal fitting attached to a flange of a grooved steel such as H-shaped steel.

吊り金具は、天井等から梁状に延びているＨ型鋼等の溝形鋼から該溝形鋼に穴を開けることなく吊りボルトを下げる場合に用いられている。   The hanging metal fitting is used when a hanging bolt is lowered from a grooved steel such as an H-shaped steel extending in a beam shape from a ceiling or the like without making a hole in the grooved steel.

溝形鋼への吊り金具の取付けは、該溝形鋼の水平のフランジに対して横方向から差し込まれた後に該フランジを上下から挟着握持することで固定することで行われている。   Attachment of the hanging metal fitting to the grooved steel is performed by inserting the flange from a horizontal direction with respect to the horizontal flange of the grooved steel and then fixing the flange by clamping the flange from above and below.

しかし、このような取付構成を有する吊り金具は、横方向に荷重が作用した場合に脱落し易いという特有の問題点を有している。   However, the hanging metal fitting having such a mounting configuration has a particular problem that it easily drops off when a load is applied in the lateral direction.

このため、特許文献１〜３等に記載されている補強金具によって固定を補強することが行われている。   For this reason, fixing is reinforced by the reinforcing metal fittings described in Patent Documents 1 to 3 and the like.

特許第３５８７８０１号Japanese Patent No. 3587801 特許第３５３８７７８号Japanese Patent No. 3538778 特許第２７４７６６７号Japanese Patent No. 2747667 特許第３７４３９０６号Japanese Patent No. 3743906 実用新案登録第１４９５５４７号Utility model registration No. 1495547

特許文献１及び２に記載の技術は、溝形鋼のフランジに引っ掛かる折り返し部を有する板状体からなる補助金具を取付けることで吊り金具の固定の補強を行っている。   The techniques described in Patent Documents 1 and 2 reinforce the fixation of the hanging metal fitting by attaching an auxiliary metal fitting made of a plate-like body having a folded portion that is hooked to the flange of the grooved steel.

しかしこれらの技術では、板状体の長さが調節不可能なため、種々のフランジ幅を有する溝形鋼に適用させるには種々の長さを有する板状体を用意しなければならないという欠点を有している。   However, in these techniques, since the length of the plate-like body cannot be adjusted, it is necessary to prepare plate-like bodies having various lengths in order to be applied to channel steel having various flange widths. have.

特許文献３及び４に記載の技術は、溝形鋼のフランジに引っ掛かる折曲端を有する固定板と該固定板と吊り金具とを連結するＵ字状ボルトからなる補強金具を取付けることで吊り金具の固定の補強を行っている。   The techniques described in Patent Documents 3 and 4 are provided by attaching a fixing plate having a bent plate hooked to a flange of a grooved steel and a U-shaped bolt for connecting the fixing plate and the hanging bracket to the hanging bracket. Reinforcement of fixing is performed.

しかしこの技術では、緊締具合の調整がＵ字状ボルトの一端側のみであるため、緊締具合の調整が一方側のみでしか行えず、調整範囲の融通性と調整作業の作業性の両面で欠点を有している。   However, with this technology, the tightening condition can be adjusted only on one end side of the U-shaped bolt. Therefore, the tightening condition can be adjusted only on one side, which is disadvantageous in terms of both flexibility of adjustment range and workability of adjustment work. have.

特許文献５に記載の技術は、溝形鋼のフランジに引っ掛かるフックボルトと該フックボルトの一端に螺合するナットからなる補助金具を取付けることで吊り金具の固定の補強を行っている。   The technique described in Patent Document 5 reinforces the fixing of the hanging metal fitting by attaching an auxiliary metal fitting made of a hook bolt hooked to the grooved steel flange and a nut screwed to one end of the hook bolt.

しかしこの技術では、フランジに対してフックボルトが点接触であるため、荷重が掛かった際にぐらつきが生じ易いという欠点を有していると共に、緊締具合の調整がフックボルトの一端側のみであるため、緊締具合の調整作業が一方側のみでしか行えず、調整範囲の融通性と調整作業の作業性の両面で欠点を有している。   However, in this technique, since the hook bolt is in point contact with the flange, there is a drawback that wobbling is likely to occur when a load is applied, and the adjustment of the tightening condition is only on one end side of the hook bolt. Therefore, the adjustment operation of the tightening condition can be performed only on one side, and there are drawbacks in both the flexibility of the adjustment range and the workability of the adjustment operation.

そこで本考案の課題は、種々のサイズのフランジを有する溝形鋼に対応可能であり、ぐらつきが生じ難い安定した補強が可能であり、両方向からの緊締具合の調整が可能な調整範囲が広く作業性が良好な吊り金具用補強金具を提供することにある。   Therefore, the problem of the present invention is that it can be applied to channel steel with flanges of various sizes, can be stably reinforced with little wobbling, and has a wide adjustment range in which the tightening degree can be adjusted from both directions. An object of the present invention is to provide a reinforcing metal fitting for a hanging metal fitting having good properties.
