Description

本発明は吊り治具に係り、重量のあるコンクリート製品等で吊支するのに大きな力を必要とする物品、例えばカルバートや、単体ではそれほど重量はないが幾つも連続して成形されるような下水道函体等であって、外面の開口端が広く、内端が狭くなった楔溝を備えた物品に適用して、吊支を容易にするためのものに関する。   The present invention relates to a hanging jig, such as an article that requires a large force to be suspended by a heavy concrete product, such as a culvert or a single piece that is not so heavy but is continuously formed. The present invention relates to a sewer box or the like, which is applied to an article provided with a wedge groove having a wide open end on the outer surface and a narrow inner end to facilitate a suspension support.

楔作用を利用した締着法は広く行われている。例えば、ワイヤで重量物を吊り下げて、ジャッキによりリフトアップ又はリフトダウンするようなときに使用されるジャッキ用チャック装置が特許文献１に開示されている。   Fastening methods using wedge action are widely used. For example, Patent Document 1 discloses a jack chuck device that is used when a heavy object is suspended by a wire and lifted up or down by a jack.

特開平１１−１２４３００号公報 （段落０００１参照）JP 11-124300 A (see paragraph 0001)

例えば、コンクリート製のボックスカルバートのように重量のある物品を運搬する場合、載置場所から吊支して車両等に搭載する必要がある。工場生産品の場合は吊りボルトを予め製品に埋設しておけるので、フックをこの吊りボルトに係合させて吊り上げられる。
経年劣化等でこのような既設の旧物品を新品と交換する場合、旧物品を設置場所から掘り出す必要があるが、吊りボルトが無いとフック等を旧物品に引っ掛けて吊り上げることになり、大変な作業となる。特許文献１に開示の技術は、旧物品にワイヤを取り付けるやり方に関しては何ら言及も示唆もしておらず、本発明の先行技術としては不十分である。 For example, when a heavy article such as a box culvert made of concrete is transported, it is necessary to hang it from a placement place and mount it on a vehicle or the like. In the case of a factory-produced product, a suspension bolt can be embedded in the product in advance, so that the hook can be lifted by engaging with this suspension bolt.
When replacing such existing old items with new ones due to aging, etc., it is necessary to dig out the old items from the installation location. It becomes work. The technique disclosed in Patent Document 1 makes no mention or suggestion regarding a method of attaching a wire to an old article, and is insufficient as a prior art of the present invention.

交換の対象となる物品の場合、その一面に排水用の透孔が開いているものがある。この透孔は、目詰まりを防ぐためと、ハイヒールの踵が落ち込むのを防ぐため、その一面で広く開口し、他面が狭く開口する楔状となっている。 In the case of an article to be exchanged, there is an article having a drainage hole on one side. In order to prevent clogging and to prevent the heel of the high heel from falling, the through hole has a wedge shape with a wide opening on one surface and a narrow opening on the other surface.

本発明はこの楔状の透孔を利用して、簡単に重量のある物品を吊支できる吊り治具を提供することを目的とする。 An object of the present invention is to provide a hanging jig capable of easily hanging a heavy article using the wedge-shaped through hole.

（請求項１）本発明に係る吊り治具は、少なくとも一面で縮寸する楔孔を備えた物品用で、楔体と楔子を包含する。該楔体は板状で該物品の該楔孔に緩合する幅を有しかつ透孔を備え、該透孔の周壁面の一部に楔部が設けられている。該楔子は板状で該楔体の該透孔に緩合する幅を有する。そして、該楔体を該物品の該楔孔に緩合し、該楔子を、該楔体の該透孔を通して、該楔部と対向させることにより、該楔体に引張力が作用したとき該楔孔と該楔部の楔作用で該楔子を該楔孔面に圧接して該物品を吊支するようになっている。 (Claim 1) A suspension jig according to the present invention is for an article having a wedge hole which is reduced in size on at least one surface, and includes a wedge body and a wedge. The wedge body is plate-shaped, has a width that loosely fits into the wedge hole of the article, and has a through hole. The wedge is plate-shaped and has a width that loosely fits into the through hole of the wedge body. Then, the wedge body is loosely fitted into the wedge hole of the article, and the wedge element is opposed to the wedge portion through the through-hole of the wedge body, whereby when the tensile force acts on the wedge body, The wedge is pressed against the wedge hole surface by the wedge action of the wedge hole and the wedge portion to suspend the article.

物品の楔孔に楔体と楔子をセットし、楔体の透孔にクレーン等のフックを掛合してこの楔体を引き上げると、楔体は楔孔の壁面に接触しながら移動する。この壁面からの分力で楔子は水平方向へ移動して反対側の壁面に押し付けられ、引抜き力が大きくなればなるほど、楔子を楔孔面に圧接し、大きな引抜き力を物品に与えてこれを吊支する。 When a wedge body and a wedge are set in a wedge hole of an article, a hook such as a crane is engaged with the through hole of the wedge body and the wedge body is pulled up, the wedge body moves while contacting the wall surface of the wedge hole. Due to the component force from the wall surface, the wedge moves horizontally and is pressed against the opposite wall surface, and as the pulling force increases, the wedge member is pressed against the wedge hole surface, and a large pulling force is applied to the article. Suspend.
