【００１２】 図３〜図５は上記インサート１５の第２〜第４実施例を示す。まず、図３は主 体１６、栓体１７および突起体１８を第１実施例と同様にプラスチック材により 一体成形するとともに、この成形時に主体１６の左端外周に環状の溝１６ｃを形 成し、主体１６と栓体１７との連結部に環状の薄肉部１６ｄを形成する。また図 ４および図５は、主体１６と栓体１７および突起体１８とを別体に形成し、主体 １６は金属材またはプラスチック材により形成し、栓体１７および突起体１８は プラスチック材により一体に形成するとともに、栓体１７の右面に小径の取付け 軸部１７ａを一体に形成し、この取付け軸部１７ａを主体１６の左端に圧入嵌合 させる。この場合、図４においては主体１６の嵌合孔１６ａを等径かつ平滑な面 に形成し、また図５においては、左部の嵌合孔１６ａ−１を右部の嵌合孔１６ａ −２よりも大径に、かつ両者間に段部１６ａ−３を有する段付きの嵌合孔１６ａ に形成する。なお図２中、２４は支持管８ｂの取付け基部の下部側に形成した排 出口である。[0012] 3 to 5 show second to fourth embodiments of the insert 15. First, Figure 3 is mainly The body 16, the plug body 17, and the protrusion 18 are made of plastic material as in the first embodiment. In addition to being integrally molded, an annular groove 16c is formed on the outer periphery of the left end of the main body 16 during this molding. Then, an annular thin portion 16d is formed at the connecting portion between the main body 16 and the plug body 17. See also 4 and FIG. 5, the main body 16 and the plug body 17 and the projection body 18 are formed as separate bodies. 16 is made of a metal material or a plastic material, and the plug body 17 and the projection body 18 are It is made of plastic material and attached to the right side of the plug body 17 with a small diameter.

In FIG. 2, reference numeral 24 denotes a drain formed on the lower side of the mounting base of the support tube 8b. It is the exit.
【００１３】 次に上記実施例の作用、効果について説明する。外枠８に固着した支持管８ｂ に支持軸２０を嵌合させ、止めピン２３を挿通して支持軸２０を支持管８ｂに固 定し、該支持軸２０の先端部２０ｃにインサート１５を嵌合支持する。次いで外 枠８を内枠７に接近させると、突起体１８の先端部が小面積で内枠７に当接し、 インサート１５は外枠８と内枠７とで挾持されて軸方向移動不能にかつ支持軸２ ０と略同軸に保持される。この状態で成形室１０内に生コンクリートを充填し、 これを硬化させて成形する。この場合、突起体１８の先端部が内枠７に当接して おり、この当接部には生コンクリートが充填されなくなるが、上記先端部は小面 積であるので成形品の品質に影響を及ぼすことはない。また嵌合孔１６ａの右端 はＯリングによりシールされ、生コンクリートの液が嵌合孔１６ａ内に流入しな くなる。また取付け孔８ａと支持軸２０との嵌合部から漏洩した生コンクリート の液は、排出口２４から外部に排出され、支持軸２０と支持管８ｂとの嵌合部に 侵入しなくなり、支持軸２０が支持管８ｂに固着されなくなる。[0013] Next, the operation and effect of the above embodiment will be described. Support tube 8b fixed to the outer frame 8 The support shaft 20 is fitted to the support shaft 20, and the stop pin 23 is inserted to fix the support shaft 20 to the support tube 8b. Then, the insert 15 is fitted and supported on the tip portion 20c of the support shaft 20. Then outside When the frame 8 is brought close to the inner frame 7, the tips of the projections 18 come into contact with the inner frame 7 in a small area, The insert 15 is sandwiched between the outer frame 8 and the inner frame 7 so as to be immovable in the axial direction and to support the support shaft 2. It is held substantially coaxial with 0. In this state, the molding chamber 10 is filled with ready-mixed concrete, This is hardened and molded. In this case, the tip of the protrusion 18 contacts the inner frame 7 Since this contact part is not filled with fresh concrete, the above-mentioned tip part is a small face. Since it is a product, it does not affect the quality of the molded product. The right end of the fitting hole 16a Is sealed by an O-ring so that the liquid of fresh concrete does not flow into the fitting hole 16a. Become Also, fresh concrete leaked from the fitting portion between the mounting hole 8a and the support shaft 20. Liquid is discharged to the outside from the discharge port 24, and is discharged to the fitting portion between the support shaft 20 and the support pipe 8b. The support shaft 20 is no longer invaded, and is not fixed to the support pipe 8b.
【００１４】 次いで、外枠８を外側方に回動させると、支持軸２０がインサート１５内を摺 動して外方に離脱する。この場合、流通孔１９から嵌合孔１６ａ内に外気が流入 するので、支持軸２０はインサート１５から円滑に離脱する。そして、インサー ト１５の嵌合孔１６ａはコンクリート成形品２５の外側面に開口し、この部に吊 り具２６（図３）を外側（右方）から嵌合係止させることにより、上記コンクリ ート成形品２５を吊り揚げることができる。[0014] Next, when the outer frame 8 is rotated outward, the support shaft 20 slides inside the insert 15. It moves and separates to the outside. In this case, outside air flows from the circulation hole 19 into the fitting hole 16a. Therefore, the support shaft 20 is smoothly separated from the insert 15. And the inserter The fitting hole 16a of the grate 15 is opened on the outer surface of the concrete molded product 25 and is hung on this part. By fitting and locking the fitting 26 (FIG. 3) from the outside (right side), The molded article 25 can be hoisted.
【００１５】 この場合、図３〜図５に示すインサート１５は、栓体１７と主体１６との連結 力が小さいため、次の如くして栓体１７を主体１６から離脱させ、吊り具２６を コンクリート成形品２５の内側（左方）から嵌合孔１６ａに嵌合係止させること ができる。即ち、突起体１８の先端が覗いているコンクリート成形品２５の内面 側の周囲をハンマー等で衝撃を加えて除去し、突き棒（図示省略）を外（右）側 からインサート１５内に挿入し、該突き棒により栓体１７を内（左）方に押すと 、該栓体１７が主体１６から離脱し、嵌合孔１６ａがコンクリート成形品２５の 内面側に開口する。これにより、上記吊り具２６を内側（左方）から上記嵌合孔 １６ａに嵌合係止させ、コンクリート成形品２５を吊り揚げることができる。[0015] In this case, the insert 15 shown in FIGS. 3 to 5 is a connection between the plug body 17 and the main body 16. Since the force is small, the stopper 17 is disengaged from the main body 16 and the lifting tool 26 is Fitting and locking from inside (left side) of the concrete molded product 25 into the fitting hole 16a You can That is, the inner surface of the concrete molded product 25 in which the tip of the protrusion 18 is seen The periphery of the side is impacted with a hammer etc. and removed, and the stick (not shown) is placed on the outside (right) side. From the inside into the insert 15 and push the plug 17 inward (left) with the thrust bar. , The plug 17 is removed from the main body 16, and the fitting hole 16a is Open to the inner surface side. As a result, the suspending tool 26 is inserted into the fitting hole from the inside (left side). The concrete molded product 25 can be lifted by fitting and locking with the 16a.
【００１６】 また図５においては、端部に大径の駒２６ａを有する吊り具２６を嵌合孔１６ ａ内に挿通すると、上記駒２６ａが嵌合孔１６ａの段部１６ａ−３に係合し、こ れにより上記吊り具２６が吊り揚げ時に不用意に離脱しなくなる。[0016] Further, in FIG. 5, the suspending tool 26 having the large diameter piece 26a at the end is provided with the fitting hole 16 When it is inserted into a, the piece 26a is engaged with the step portion 16a-3 of the fitting hole 16a, As a result, the lifting tool 26 does not accidentally come off during lifting.
【００１７】[0017]
以上の説明から明らかな如く、本考案は筒状の主体の一方の軸端を閉塞する栓 体に、突出端部が小径となる可橈性の突起体を設けるようにしたので、インサー トを型枠の両壁で挾持しながら、突起体のコンクリート成形品からの露出量を少 なくすることができる。またインサートを型枠の両壁で挾持することができるの で、インサートを型枠の支持軸に遊嵌させることにより、該インサートの型枠へ の取付けおよび成形品の離型を迅速にできるようにしながら、インサートは型枠 に高精度に取付けられることになる等の効果を奏する。 As is apparent from the above description, the present invention is a plug for closing one axial end of a tubular main body. Since the body is provided with a slidable protrusion whose protruding end has a small diameter, the inserter While holding the mold on both walls of the formwork, the amount of exposure of the protrusion from the concrete molded product is reduced. It can be lost. You can also hold the insert on both walls of the formwork. Then, by loosely fitting the insert to the support shaft of the mold, The inserts allow the molds to form while allowing for quick mounting and demolding of molded parts. There is an effect that it can be attached to the high precision.
