Description

本発明は、例えば、天井スラブ等の構造体に吊設される空調機器、ケーブルラック、ダクト、天井下地材等の吊設部材の振れ止め措置として、吊設部材を吊り下げ支持する吊りボルトに夫々の端部が取り付けられて、互いに交差する２本の振れ止め用ボルトとを連結するなど、２本の棒状体を交差姿勢で連結する棒状体用交差連結具に関する。   The present invention provides, for example, a suspension bolt for hanging and supporting a suspension member as a steadying measure for suspension members such as an air conditioner, a cable rack, a duct, and a ceiling base material suspended from a structure such as a ceiling slab. The present invention relates to a cross-connecting member for rod-like bodies that connects two rod-like bodies in a crossing posture, such as connecting two steady-state bolts that are attached to each end and that cross each other.

例えば下記特許文献１には、耐震補強用の吊りボルト振れ止め装置が記載されている。この吊りボルト振れ止め装置は、天井部より垂下された振れ止め措置対象の吊りボルトの隣り合うものどうし間に振れ止め用の筋交いを１本ずつ入れ、筋交いの上端部を筋交い取付金具によって隣り合う一方の吊りボルトの上端部に取り付け、筋交いの下端部を筋交い取付金具により他方の吊りボルトの下端部に取り付け、しかして隣り合う吊りボルト間に配設した筋交いにより地震発生時における吊りボルトの揺れを抑えて、天井材等の損壊、落下を防止するようにしたものである。   For example, Patent Literature 1 below describes a suspension bolt steadying device for seismic reinforcement.

First, as shown in (a), for example, with the left hand, The other locking bolt 4b is held in a state of being pressed against each other, and one of the engaging portions 7 of the cross connector 5 held by the right hand is moved from the locking bolt 4b as shown in FIG. Engage with the steady-state bolt 4a from the lower side (back side) at the upper position.

一方の係合部７を振れ止め用ボルト４ａに対し下側（背面側）から係合させたならば、図４の(b) に示すように、交差連結具５の係合操作部片１３を左手で掴んで、圧接用ブリッジ部９を振れ止め用ボルト４ｂの上に押し付けるような状態から、この圧接用ブリッジ部９が振れ止め用ボルト４ａに対し斜交する状態となるように、係合操作部片１３を左手で掴んで図４の(b) の左方へ引き寄せながら、振れ止め用ボルト４ａの下側（背面側）へ潜り込ませるように強く押し込んで、他方の係合部８を、振れ止め用ボルト４ｂの下方位置で振れ止め用ボルト４ａに対し下側（背面側）から係合させて、交差連結具５を図２の(a) ，(b) に示すような状態とする。これによって、一方の振れ止め用ボルト４ａ上に交差状態に重なった他方の振れ止め用ボルト４ｂは、圧接用ブリッジ部９の山形頂部９ｏと前記一方の振れ止め用ボルト４ａとの間で強力に圧接されて保持固定された状態となり、しかして両方の振れ止め用ボルト４ａ，４ｂは所定の交差姿勢で連結される。   If one of the engaging portions 7 is engaged with the steady-state bolt 4a from the lower side (rear side), as shown in FIG. 4B, the engaging operation piece 13 of the cross connector 5 is obtained. From the state in which the pressure-contact bridge portion 9 is pressed onto the steady-state bolt 4b, so that the pressure-contact bridge portion 9 is obliquely crossed with the steady-state bolt 4a. While holding the joint operation piece 13 with the left hand and pulling it to the left as shown in FIG. 4B, it pushes strongly so as to sink into the lower side (rear side) of the steady-state bolt 4a, and the other engagement portion 8 Are engaged with the steady-state bolt 4a from the lower side (back side) at a position below the steady-state bolt 4b, and the cross-connecting device 5 is in a state as shown in FIGS. 2 (a) and 2 (b). And As a result, the other steadying bolt 4b, which is overlapped on the one steadying bolt 4a, is powerfully connected between the mountain-shaped top 9o of the pressure welding bridge 9 and the one steadying bolt 4a. The two bolts 4a and 4b are connected in a predetermined crossing posture.

この棒状体用交差連結具５では、上記実施形態の説明のように一方の振れ止め用ボルト４ａ上に交差状態に重なった他方の振れ止め用ボルト４ｂが、圧接用ブリッジ部９の山形頂部９ｏと一方の振れ止め用ボルト４ａとの間で強力に圧接されて保持された状態となることにより、両方の振れ止め用ボルト４ａ，４ｂが交差姿勢で連結されることになるが、圧接用ブリッジ部９の山形頂部９ｏと一方の振れ止め用ボルト４ａとの間で圧接保持された状態の他方の振れ止め用ボルト４ｂは、一方の振れ止め用ボルト４ａに対し交差角度が変更可能であるため、２本の振れ止め用ボルト４ａ，４ｂは、ある一定の交差角度姿勢に限らず、任意の交差角度姿勢で連結可能となる。   In this cross-connector 5 for rod-like bodies, as described in the above embodiment, the other steady-state bolt 4b overlapped on the one steady-state bolt 4a is connected to the mountain-shaped top portion 9o of the pressure-bonding bridge portion 9. And one of the steady-state bolts 4a are held in a state where they are strongly pressed against each other, so that both steady-state bolts 4a and 4b are connected in an intersecting posture. The crossing angle of the other steadying bolt 4b that is held in pressure contact between the chevron 9o of the portion 9 and one steadying bolt 4a can be changed with respect to the one steadying bolt 4a. The two steady rest bolts 4a and 4b can be connected not only to a certain crossing angle posture but also to any crossing angle posture.

また、この棒状体用交差連結具５では、上記のように２本の振れ止め用ボルト４ａ，４ｂが任意の交差角度姿勢で連結可能であるが、一方の振れ止め用ボルト４ａに対し他方の振れ止め用ボルト４ｂがその軸方向にスライドしないように連結可能となる。この場合、２本の棒状体、例えば２本の振れ止め用ボルト４ａ，４ｂは、ネジ棒（ボルト）であることが好ましく、このネジ棒のネジ部によって上記スライドが有効に阻止される。これは、ネジ棒（ボルト）の場合には、そのネジ部が滑り止め機能を有効に発揮し、線状体６からなる係合部７，８及び圧接用ブリッジ部９がそのネジ部に掛止されるからである。   Further, in this cross-connector 5 for rod-like bodies, as described above, the two steady-state bolts 4a and 4b can be coupled at an arbitrary intersecting angle posture, but the other steady-state bolt 4a is connected to the other steady-state bolt 4a. The steadying bolt 4b can be connected so as not to slide in the axial direction. In this case, it is preferable that the two rod-like bodies, for example, the two anti-rest bolts 4a and 4b, are screw rods (bolts), and the sliding is effectively prevented by the screw portions of the screw rods. This is because in the case of a screw rod (bolt), the screw portion effectively exhibits the anti-slip function, and the engaging portions 7 and 8 made of the linear body 6 and the pressure contact bridge portion 9 are hooked on the screw portion. Because it is stopped.

以上の実施形態の説明から分かるように、この棒状体用交差連結具５によれば、一方の棒状体４ａ上に他方の棒状体４ｂを交差させた２本の棒状体４ａ，４ｂを連結するのに、交差連結具５の一方の係合部７を、一方の棒状体４ａに対してその下側（背面側）から係合させた後、圧接用ブリッジ部９を他方の棒状体４ｂの上に押し付けるような状態から、この圧接用ブリッジ部９が一方の棒状体４ａに対し斜交する状態となるようにして、他方の係合部８を一方の棒状体４ａに対し下側（背面側）から係合させることによって、一方の棒状体４ａ上に交差状態に重なった他方の棒状体４ｂが、圧接用ブリッジ部９の山形頂部９ｏと一方の棒状体４ａとの間で強力に圧接されて保持固定された状態となるから、２本の棒状体４ａ，４ｂを任意の交差角度で簡単に連結することができる。   As can be seen from the description of the above embodiment, according to the rod-like body cross connector 5, the two rod-like bodies 4a and 4b obtained by crossing the other rod-like body 4b on one rod-like body 4a are coupled. However, after engaging one engaging portion 7 of the cross connector 5 from the lower side (rear side) with respect to one rod-like body 4a, the pressure-bonding bridge portion 9 is connected to the other rod-like body 4b. From the state of pressing upward, the pressure-bonding bridge portion 9 is in a state of obliquely intersecting the one rod-shaped body 4a, and the other engagement portion 8 is placed on the lower side (back surface) with respect to the one rod-shaped body 4a. By engaging from the side, the other rod-like body 4b that overlaps one rod-like body 4a is pressed strongly between the mountain-shaped top portion 9o of the pressure-welding bridge portion 9 and the one rod-like body 4a. The two rod-like bodies 4a and 4b can be arbitrarily held because they are held and fixed. It can be easily connected by a difference angle.

また、一方の係合部７は、前記一方の棒状体４ａに対し係脱自在に係合するＵ字状本体１０と、このＵ字状本体１０における圧接用ブリッジ部９につながる端部７ｂと反対側の端部７ａから前記係合部７の開口部側に屈曲突入して前記一方の棒状体４ａからの離脱をし難くするための突入片１１とから構成されたもので、交差連結具５による棒状体４ａ，４ｂの連結作業中に突入片１１によって、係合部７が棒状体４ａから簡単には離脱しないため、連結作業を一層迅速容易に行なうことができる。   One engaging portion 7 includes a U-shaped main body 10 that is detachably engaged with the one rod-shaped body 4a, and an end portion 7b that is connected to the pressure-contact bridge portion 9 in the U-shaped main body 10. A cross-connecting tool comprising a protruding piece 11 for bending and protruding from the opposite end portion 7a to the opening side of the engaging portion 7 to make it difficult to separate from the one rod-like body 4a. Since the engaging portion 7 is not easily detached from the rod-like body 4a by the protruding piece 11 during the joining operation of the rod-like bodies 4a, 4b by 5, the joining operation can be performed more quickly and easily.

また、他方の係合部８は、前記一方の棒状体４ａに対し係脱自在に係合するＵ字状本体１２と、このＵ字状本体１２の先端部からＵ字状本体１２に一部沿うように二重線状に延出して形成された係合操作部片１３とから構成されたもので、係合操作部片１３によって棒状体４ａに対する係合部８の係合操作を容易に行なうことができる。   The other engaging portion 8 includes a U-shaped main body 12 that is detachably engaged with the one rod-shaped body 4a, and a part from the distal end of the U-shaped main body 12 to the U-shaped main body 12. It is comprised from the engagement operation part piece 13 extended and formed in double line shape so that engagement operation of the engagement part 8 with respect to the rod-shaped body 4a by the engagement operation piece 13 can be carried out easily. Can be done.

特に、この棒状体用交差連結具５は、１本のバネ鋼線からなる線状体６によって形成されるもので、構造が極めて簡素で、製作が容易であるため、コストの低廉化を期することができると共に、棒状体４ａ，４ｂの連結作業を迅速容易に行なうことができる。   In particular, the cross-connecting tool 5 for a rod-shaped body is formed by a linear body 6 made of a single spring steel wire, has a very simple structure, and is easy to manufacture. In addition, the connecting work of the rod-like bodies 4a and 4b can be performed quickly and easily.
