The present invention relates to a metal fitting that can be prevented from falling off.

従来、この種、形鋼材のフランジ部に開口部を挿入し、締付けボルトにより上下方向から挟持して固定する略コの字状の取付け金具の脱落防止具として、取付け金具の板幅より大の平板状基部の一端側に前記フランジ部の端面に係合する第1の係合部を備え、他端側には前記取付け金具の上下に配置する第1及び第2の腕部を連結する連結部が挿通する係合穴を有する第2の係合部を備え、前記取付け金具が締付けボルトの緩みにより形鋼材のフランジ部から抜け出す方向に移動する際に、前記係合穴に前記連結部が係合すると共に、前記フランジ部に第1の係合部が係合することで取付け金具の脱落を防止する脱落防止具が開示されている。(特開2002−339937号)  Conventionally, as a tool for preventing the dropout of a substantially U-shaped mounting bracket that is inserted into the flange portion of this type and shape steel material, and clamped from the top and bottom with a clamping bolt, it is larger than the plate width of the mounting bracket. A first engaging portion that engages with an end surface of the flange portion is provided on one end side of the flat plate-like base portion, and a first arm portion and a second arm portion that are arranged above and below the mounting bracket are connected to the other end side. A second engaging portion having an engaging hole through which the connecting portion is inserted, and when the mounting bracket moves in a direction of coming out of the flange portion of the shaped steel member due to loosening of the tightening bolt, the connecting portion is inserted into the engaging hole. A drop-off prevention tool is disclosed that engages and prevents a fitting from falling off by engaging a first engagement portion with the flange portion. (Japanese Patent Laid-Open No. 2002-339937)

また、取付け金具の板幅より大の平板状基部の一端側に前記フランジ部の端面に係合する係合部を備え、他端側には前記係合部と同じ側に立設された立ち上り部の先端に前記締付けボルトのボルト軸が挿通する挿通穴を有する折返し部を備え、前記取付け金具が締付けボルトの緩みにより形鋼材のフランジ部から抜け出す方向に移動する際に、前記挿通穴に前記締付けボルトのボルト軸が係合すると共に、前記フランジ部に係合部が係合することで取付け金具の脱落を防止する脱落防止具が開示されている。(特開2002−339919号)  In addition, an engaging portion that engages with the end surface of the flange portion is provided on one end side of the flat base portion that is larger than the plate width of the mounting bracket, and the other end side is provided on the same side as the engaging portion. A folding portion having an insertion hole through which the bolt shaft of the tightening bolt is inserted at the tip of the portion, and when the mounting bracket moves in the direction of coming out of the flange portion of the shaped steel material due to the loosening of the tightening bolt, There has been disclosed a drop-off preventing tool that prevents the mounting bracket from falling off by engaging the bolt shaft of the tightening bolt and engaging the flange with the engaging portion. (Japanese Patent Laid-Open No. 2002-339919)

上記従来の方法において、両者の脱落防止具は、取付け金具の板幅より大の平板状基部の一端側に前記フランジ部の端面に係合する係合部を備え、他端側に取付け金具の連結部が挿通する係合穴、あるいは、取付け金具の締付けボルトの軸を挿通する挿通穴を備えたものであるが、締付けボルトの軸を挿通する挿通穴を備えたものでは、締付けボルトのボルト軸に対して部分的に過度の曲げ力が掛かるため、抜け出す荷重に対して強度的に不利になり、また、大きな強度も期待できない。
連結部を挿通する係合穴を備えたものは、抜け出す荷重に対して金具全体で支持するため強度的な期待はできるものの、脱落防止具の製品自体が大きくなり、経済的に不利になり、また、作業性も悪い。
また、両者共、平板状基部が取付け金具の板幅より大のため、前記取付け金具の下側に配置する第2の腕部の両側板に設けた鋸歯部が脱落防止具の取付けにより形鋼材のフランジ部に直接接触できず、平板状基部を介した状態になるために、取付け金具自体の固定力及び、滑り抑制力の低下に影響を与える可能性があるなどの問題点が生じていた。
In the above conventional method, both of the drop-off prevention tools include an engaging portion that engages with the end surface of the flange portion on one end side of the flat base portion larger than the plate width of the mounting bracket, and the other end side of the mounting bracket. It has an engagement hole through which the connecting part is inserted, or an insertion hole through which the shaft of the fastening bolt of the mounting bracket is inserted, but if it has an insertion hole through which the shaft of the fastening bolt is inserted, the bolt of the fastening bolt Since an excessive bending force is partially applied to the shaft, it is disadvantageous in terms of strength against the load that comes out, and high strength cannot be expected.
The one with the engagement hole that passes through the connecting part is supported by the whole bracket against the load that comes out, but it can be expected to be strong, but the product of the fall-off prevention device itself becomes large, which is economically disadvantageous, Also, workability is poor.
Further, in both cases, since the flat base portion is larger than the plate width of the mounting bracket, the saw-tooth portions provided on the both side plates of the second arm portion arranged below the mounting bracket are formed by mounting the drop-off prevention tool. Since it cannot be in direct contact with the flange portion of the metal plate and is in a state through the flat base portion, there has been a problem that it may affect the fixing force of the mounting bracket itself and the reduction of the slip suppression force. .
