Description

本発明は、主に冷媒配管用として用いられるラックの振れ止め金具に係り、特に、施工後の外観を重視しながらラックの移動を確実に防止することができるラックの振れ止め金具に関する。   The present invention relates to a rack steadying bracket mainly used for refrigerant piping, and more particularly to a rack steadying bracket capable of reliably preventing rack movement while placing importance on the appearance after construction.

冷媒配管や電線材を収納するラックの中でも、屋上に設置されることが多い冷媒配管用のラックは、施工後の外観が重視される。そのため、この冷媒配管用のラックを固定する振れ止め金具は、ラックの親桁の内側に装着されるものが採用されている。   Among racks for storing refrigerant pipes and electric wire materials, the refrigerant pipe racks often installed on the roof place importance on the appearance after construction. For this reason, as the steady rest fitting for fixing the refrigerant piping rack, one mounted on the inner side of the main beam of the rack is adopted.

図９乃至図１１に、従来から使用されている振れ止め金具１００を示している。この振れ止め金具１００は、ラックＱの親桁Ｑ１下端部に屈曲された下部屈曲片Ｑ２の上に重ね、この下部屈曲片Ｑ２を圧着するタイプの振れ止め金具１００である。すなわち、チャンネル材製の架台Ｐの上部開口部Ｐ１にラックＱの親桁Ｑ１を設置し、この親桁Ｑ１の下部屈曲片Ｑ２に振れ止め金具１００を重ねて使用する（図１１参照）。そして、振れ止め金具１００を貫通する止着ボルト２０と、架台Ｐの開口部Ｐ１内のリップ部Ｐ２に係止した中ナット４０とをネジ止めすることで、ラックＱの下部屈曲片Ｑ２を振れ止め金具１００で圧着固定するものである（図１０参照）。   9 to 11 show a steady rest 100 used conventionally. This steady rest 100 is a steady rest 100 of the type which piles up on the lower bending piece Q2 bent to the lower end part of the main girder Q1 of rack Q, and crimps this lower bending piece Q2. In other words, the parent girder Q1 of the rack Q is installed in the upper opening P1 of the channel material base P, and the steady rest metal fitting 100 is overlapped with the lower bent piece Q2 of the parent girder Q1 (see FIG. 11). Then, by fastening the fastening bolt 20 that penetrates the steady mounting bracket 100 and the intermediate nut 40 that is locked to the lip portion P2 in the opening P1 of the gantry P, the lower bent piece Q2 of the rack Q can be swung. It is fixed by crimping with a stopper 100 (see FIG. 10).

ところが、従来の振れ止め金具１００によると、ラックＱの下部屈曲片Ｑ２が振れ止め金具１００で圧着されているだけなので、ラックＱの横方向（図１０の矢印方向）に加わる外力には極めて弱く、架台Ｐから簡単に外れてしまうおそれがあった。特に、屋上での設置が多い冷媒配管用のラックＱなどは、多くの作業者等が触れ易い場所に設置されているので、天井裏などに設置される電線材用のラックＱに比べて深刻な課題になっている。   However, according to the conventional steady rest 100, the lower bent piece Q2 of the rack Q is only crimped by the steady rest 100, so that it is very weak to the external force applied in the lateral direction of the rack Q (arrow direction in FIG. 10). There was a risk that it would easily come off the base P. In particular, the rack Q for refrigerant piping, which is often installed on the roof, is installed in a place where many workers can easily touch, so it is more serious than the rack Q for electric wires installed on the back of the ceiling. It is a difficult issue.

そこで、当出願人は先に、特許文献１に記載のラック用振れ止め金具を発明している。この振れ止め金具は、溝形鋼のフランジ上に載置するラックの下部屈曲片を固定するものである。すなわち、ラックの下部屈曲片の上面に重ねる押さえ板と、ラックを載置した溝形鋼のフランジの下面に係止する下部金具とを設け、これらを角根ボルトで連結する。このとき、押さえ板の一端に、溝形鋼のフランジに係止する規制板を設け、下部金具にフランジの端部に当接する上板を設けることで、ラックの固定力を高めたものである。
特許第３３６７０５２号公報 Therefore, the applicant of the present invention has invented the rack steadying bracket described in Patent Document 1. This steady rest metal fitting fixes the lower bent piece of the rack placed on the flange of the channel steel. That is, a pressing plate that is superimposed on the upper surface of the lower bent piece of the rack and a lower metal member that is engaged with the lower surface of the flange of the grooved steel on which the rack is placed are provided and connected by square root bolts. At this time, the holding plate is provided with a restricting plate that is engaged with the flange of the grooved steel at one end, and an upper plate that is in contact with the end of the flange is provided on the lower metal fitting, thereby increasing the fixing force of the rack. .
Japanese Patent No. 3367052

特許文献１の振れ止め金具によって、ラックの親桁の内側に装着されるタイプの振れ止め金具に強力な固定力を付与することに成功した。ところが、この固定力は、ラックの親桁内側に向けて加わる外力に対して優れた効果を発揮するが、ラックの親桁外側に向けて加わる外力に対しては、依然として弱い傾向にあり、図１０の矢印方向に振れるおそれは未だ解消されていなかった。すなわち、この特許文献１の振れ止め金具においても、ラックの下部屈曲片を親桁内側で挟着する構造になっているからである。   With the steady rest fitting of patent document 1, it succeeded in giving a strong fixing force to the steady rest fitting of the type with which the inner side of the main beam of a rack was mounted | worn. However, this fixing force has an excellent effect on the external force applied to the inside of the rack's main beam, but it still tends to be weak against the external force applied to the outside of the rack's main beam.
