（産業上の利用分野）
本考案は、簡単な構成の連結具により隣接する
コンクリート製品を連結するための連結装置に関
するものである。[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a connecting device for connecting adjacent concrete products by means of a simple connecting device.
（従来の技術）
従来、第５図ないし８図に示されるようなコン
クリート製品の連結装置が考案されている。(Prior Art) Conventionally, devices for connecting concrete products as shown in FIGS. 5 to 8 have been devised.
これは、連結板１の一端にボルト孔２が設けら

沿つて設けられ、このボルト溝３はボルト孔２か

連結ボルト５を隣接するコンクリート製品Ｃの端
面の近傍に埋込んだ埋込みナツト６に軽く螺合し
た後に、打込片４を上方より叩過いて隣接するコ
ンクリート製品Ｃを引き寄めて各端面を密着さ
せ、その後に連結ボルト５を締込む構成のもので
ある。 This is because a bolt hole 2 is provided at one end of the connecting plate 1, and a bolt groove 3 is provided at the other end along the vertical direction, and the length of this bolt groove 3 starting from the bolt hole 2 is from the lower end. It gradually becomes shorter toward the upper end, and a driving piece 4 is provided protruding near the bolt groove 3, and each connecting bolt 5 inserted into the bolt hole 2 and the bolt groove 3 is inserted into the vicinity of the end face of the adjacent concrete product C. After being lightly screwed into the embedded embedded nut 6, the driving piece 4 is struck from above to draw the adjacent concrete products C together so that each end face is brought into close contact with each other, and then the connecting bolt 5 is tightened. It is.
この連結装置の連結具A′１，A′２は打込片４
を備えており、この打込片４を叩いて隣接するコ
ンクリート製品Ｃを互いに引き寄せるので、過つ

うことがない利点を有しているが、この打込片４
を連結板１に突設するには、金属板を曲げ加工す
ることにより連結板１と打込片４とを一体の構造
にするか、或いは別体に成形した連結板１と打込
片４とをアーク溶接により固着する構造であつ
た。 Connectors A'1 and A'2 of this connecting device are driven pieces 4
This has the advantage that the concrete products C will not be accidentally struck and damaged since the concrete products C are attracted to each other by striking this poured piece 4. 4
In order to protrude from the connecting plate 1, the connecting plate 1 and the driving piece 4 can be made into an integral structure by bending the metal plate, or the connecting plate 1 and the driving piece 4 must be formed separately. The structure was such that they were fixed together by arc welding.
このため、アーク溶接による場合は、小鉄片を
連結板１の定位置に定角度で外観上見栄えよく溶
接することは、極めて熟練を要すると共に、アー
ク溶接後に仕上げ加工を施さないと商品価値のあ
る製品とはならないという問題がある。 For this reason, when arc welding is used, it requires extremely skill to weld small pieces of iron to the fixed position of the connecting plate 1 at a fixed angle with a good appearance, and if finishing is not performed after arc welding, the commercial value is lost. The problem is that it does not become a product.
また、曲げ加工による場合は、使用材料に無駄
が生ずると共に、折曲げ加工を必要とするため製
品コストが上昇するという問題がある。 Furthermore, when bending is used, there are problems in that the materials used are wasted and the product cost increases because bending is required.
いずれの場合においても、連結板１に打込片４
を突設するには多くの製作工程が必要なため、前
もつて完成品をストツクしておく必要があつた。 In either case, the driving piece 4 is attached to the connecting plate 1.
Since many manufacturing steps were required to install the protrusion, it was necessary to stock the finished product in advance.
しかも連結するコンクリート製品Ｃは、大小軽
重の差が大きく、埋込みナツト６が埋込まれてい

している。このため、端部の厚いコンクリート製
品に使用する目的で製作されている連結具を使用

合は、打込片を叩く力を加減しなければならな
い。 Moreover, the concrete products C to be connected have a large difference in size and weight, and the thicknesses T of the ends of the concrete products C in which the embedded nuts 6 are embedded are different. For this reason, when connecting concrete products with thin ends using a connector manufactured for use with concrete products with thick ends, the force with which the concrete pieces are struck must be adjusted.
しかし、作業能率を重視する作業現場に於いて
は、常に叩き過ぎの弊害が続発し、このためコン
クリート製品の端部の破損、或いは亀裂が多発し
て多大の損害を生ずる危険が大きかつた。 However, in work sites where work efficiency is important, the negative effects of over-pounding always occur, and as a result, there is a great risk that the edges of concrete products will frequently break or crack, resulting in great damage.
（考案が解決しようとする問題点）
本考案は、上記した各問題点に鑑み、連結具の
打込片が過大な力によつて叩かれることにより、
コンクリート製品の端部に破損或いは亀裂が生ず

ある。(Problems to be solved by the invention) In view of the above-mentioned problems, the invention solves the problem when the driving piece of the connecting tool is struck by excessive force.
This was done to prevent damage or cracks from occurring at the edges of concrete products.
