Description

【0001】
【発明の属する技術分野】
本発明は円筒状のコンクリート二次製品、例えば、コンクリート柱、コンクリートパイル等の円筒状型枠にコンクリートホッパからコンクリートを払い出して充填投入するときに供給案内するコンクリートホッパの案内シュートに関する。
【0002】
【従来の技術】
コンクリート柱やコンクリートパイル等のコンクリート二次製品は、上下に分割可能な円筒状の型枠内にコンクリートを充填し、遠心成形により所定形状としている。このコンクリートの充填の際には案内シュートによりコンクリートを型枠内に誘導するようにしており、例えば、実開平5−29707号公報に記載の如く、一対の方形状の板体よりなる案内シュートを型枠の長手方向に沿って対向させると共に、その下端部を型枠内に装填した鉄筋の側部に当接させるようにしたものがある。
【0003】
【発明が解決しようとする課題】
しかしながら、案内シュートを単に型枠内の鉄筋かごの側部に当接する従来の方式では、鉄筋の中央部付近からコンクリートを充填しようとして案内シュートを鉄筋かごの中央寄りに当接させると、案内シュートの下端部と型枠の側縁部との間に隙間ができて充填しようとするコンクリートが型枠の側縁部のフランジ部に漏洩してくるおそれがある。
【0004】
また、漏洩を防止するために案内シュートを型枠の側縁部に接近させると、鉄筋かごの側部からではスランプ値が5cm以下の流動性の低い二次製品用のコンクリートを鉄筋かご内に入れにくく、鉄筋かごの側部と案内板との間にコンクリートが堆積しがちとなり、また従来例のように案内シュートにバイブレータを取り付けたとしても充填時の作業効率の低下は免れない。
【0005】
また、円筒状の型枠内にコンクリートを充填する際には、充填装置に対して型枠を移動させるのが一般的である。この円筒状の型枠は相当重いものであり、所定の位置に停止させようとしても急停止させることは難しく、そのために型枠の端部付近にコンクリートを充填する場合には型枠の端部を充填装置の下位に設けた案内シュートにぶつけないように、型枠の端部を案内シュートよりかなり手前に停止させて充填することが多い。このように、型枠の端部を案内シュートより手前に停止させて充填するということは、型枠の端部の手前で投入したコンクリートを型枠の端部に手作業で充填してやる必要があり、作業者の負担も大きくて作業効率の向上を阻むものである。
【0006】
本発明は上記の点に鑑み、二次製品用の円筒状型枠にコンクリートを充填する際、型枠の側縁部にコンクリートが漏洩したり堆積したりすることがなく、型枠内にコンクリートをスムーズに充填できるようにした二次製品用コンクリートホッパの案内シュートを提供することを目的とするものである。
【0007】
【課題を解決するための手段】
本考案は上記の目的を達成するために、請求項1記載の案内シュートは、鉄筋かごを装填した円筒状型枠内にコンクリ−トを充填するために供給案内するコンクリートホッパの案内シュ−トにおいて、前記コンクリートホッパの下位に円筒状型枠を移送する移送装置を配設し、該移送装置にて移送する円筒状型枠の長手方向に沿って一対のカバー体を対向させ、各カバー体の下端部を前記円筒状型枠の内側縁部に当接可能なように各カバー体の間隔を拡縮自在に、かつ昇降自在に配設する一方、カバー体の内側には上端部を回動自在に軸着した案内板を配設すると共に、案内板の下端部前記円筒状型枠内の鉄筋かごに当接させるようにバネ体により内方向に弾力的に押圧付勢したことを特徴としている。
【0008】
前記案内板における円筒状型枠の長手方向側の板幅をカバー体における円筒状型枠の長手方向側の板幅より幅広く形成すると共に、案内板の上端部とカバー体の内側とを回動自在に軸着する棒状体にバネ体を介装して案内板を弾力的に横移動可能としたことを特徴としている。
【0009】
【発明の実施の形態】
本発明の請求項1記載の案内シュートによれば、型枠の長手方向に沿って配設した一対のカバー体の内側に案内板を配設してあり、しかもこの案内板はバネ体により型枠の内側に向けて弾力的に付勢しているので、カバー体の下端部を型枠の内側縁部に当接させる時、案内板の下端部はカバー体より内側に離れた位置で鉄筋かごに当接することになる。これによって、型枠にコンクリートを投入する時、カバー体により型枠の内側縁部を閉塞すると共に、案内板によりコンクリートを鉄筋かごの軸心付近に誘導するので、型枠の側縁部からの漏洩を防止すると共に、主に鉄筋かごの中心部付近において充填することができ、効率的な充填作業を期待することができる。
【0010】
また、請求項2記載の案内シュートによれば、移動する型枠の端部が案内シュートに接近しすぎて案内板に接触しても、案内板はバネ体の弾力によってカバー体に沿って横移動するために衝撃を吸収でき、案内シュートを損傷させることはない。したがって、型枠の端部を案内シュートにかなり接近させて停止させることができ、型枠の端部付近へのコンクリートの充填を可能とする。
【0011】
【実施例】
以下、本発明の実施例を図面に基づいて説明する。
【0012】
図中1はコンクリートを製造するバッチャープラント(図示せず)の下部に配設した架台であって、架台1の中央部付近にはバッチャープラントにより製造したコンクリートを一時貯留して適宜払い出すようにしたコンクリートホッパ2を配設している。
【0013】
コンクリートホッパ2の下位にはコンクリート柱やコンクリートパイル等を成形する際に使用される上下分割可能とした円筒状型枠の下型枠3を搬送する移送装置4を配設し、下型枠3内には芯金となる鉄筋かご5を装填している。
【0014】
また、架台1の上部には支持フレーム6を配設し、支持フレーム6の四隅にはスプロケット7を回転軸8により軸支して回転自在に配設し、更に回転軸8の一つには回転用スプロケット9を装着すると共に、該回転用スプロケット9と駆動用モータ10に取り付けたスプロケット11とにチェーン12を巻回し、駆動用モータ10の回転を各回転軸8を介して四隅のスプロケット7に伝達するようにしている。
【0015】
前記四隅のスプロケット7にはそれぞれチェーン13を巻回すると共に、その一端部は支持フレーム6の下位に配設した枠状の昇降用フレーム14に取り付け、他端部は架台1の側部に配設した昇降用フレーム14の重量を相殺するカウンターウエイト15に取り付け、駆動用モータ10の正逆回転によりスプロケット7を正逆回転させ、昇降用フレーム14をガイド体16に沿って上下に昇降させるようにしている。
【0016】
17はコンクリートホッパ2内のコンクリートを下型枠3内に誘導するための案内シュートであって、案内シュート17は移送する下型枠3の長手方向に沿って適宜長さの方形状の一対のカバー体18を対向させ、その下端部を下型枠3の内側縁部に当接できる構造としている。
【0017】
また、カバー体18の上端部の両側にはナット19を固着し、該ナット19を左右相反する方向に螺刻したねじ棒20に螺着し、ねじ棒20の両端部を昇降用フレーム14に回転自在に支持させると共に、回転軸21及び伝動用ギヤ22を介して昇降用フレーム14に取り付けた駆動用モータ23によりねじ棒20を回転して左右のカバー体18の間隔を拡張・縮小移動できるようにしてある。
【0018】
また、昇降用フレーム14の上面にはねじ棒20と平行にスライドレール24を配設し、スライドレール24にはスライドレール24に沿って摺動するスライドユニット25を取り付けており、カバー体18の上端部の両側は前記スライドユニット25に取り付けてねじ棒20による拡張・縮小がスムーズに行えるようにしている。
【0019】
また、図4、図5に示すように、カバー体18の内側には支持片26により棒状体27を固定し、該棒状体27にはバネ体であるコイルバネ28と移動片29を装着し、移動片29を両側に装着したコイルバネ28の復元力に抗して左右に移動できるようにしている。
【0020】
前記移動片29にはコンクリートの案内ガイドとなる案内板30の上端部を固着し、棒状体27を中心にして案内板30を揺動自在とすると共に、コイルバネ28の復元力に抗して左右に横移動できるようにしている。また、案内板30をカバー体18より幅広くし、案内板30が横移動しても投入されるコンクリ−トがカバ−体18に直接当たらないようにしている。
【0021】
また、案内板30を内方向に弾力的に押圧付勢して移送する下型枠3の鉄筋かご5に当接させるために、カバー体18を貫通させた押圧部材31の先端を案内板30に当接させ、押圧部材31に装着したバネ体であるコイルバネ32の復元力によって案内板30を内方向に押圧付勢する構造としている。
【0022】
しかして、コンクリートホッパ2に貯留したコンクリートを下型枠3内に充填する時には、先ず、駆動用モータ23を駆動させてカバー体18間の間隔を下型枠3の内側縁部より若干内側となる位置に移動させ、更にモータ10を正回転駆動して昇降用フレーム14を上昇させて案内シュート17を上方に待機させておく。
【0023】
そして、鉄筋かご5を装填した下型枠3内をコンクリートホッパ2の下位に送り込み、下型枠3がコンクリートホッパ2の下位に到達すると、駆動用モータ10を逆回転して案内シュート17を降下させる。
【0024】
次に、駆動用モータ23を正回転してカバー体18の間隔を拡張する方向に移動させてカバー体18の下端部を下型枠3の内側縁部に当接させる。このとき、カバー体18の内側に配設した案内板30は、コイルバネ32により内側に押圧付勢されてその下端部は鉄筋かご5に当接するようになり、投入されるコンクリートを鉄筋かご5の中央部付近に誘導する案内ガイドとして作用する。
【0025】
カバー体18が所定の位置に固定されるとコンクリートホッパ2より所定量のコンクリートを払い出し、カバー体18より内側で案内ガイドとなっている案内板30に誘導させて下型枠3内にコンクリートを充填する。
【0026】
こうして所定量のコンクリートを充填すると、下型枠3を所定量前進させてコンクリートを順次充填していくのである。
【0027】
また、下型枠3を順次前進させて最後に下型枠3の端部付近にコンクリートを充填する時には、案内シュート17を下降させたままの状態で下型枠3を前進させ、下型枠3の端部が案内板30の端部にほぼ当接する位置にて停止させるようにする。
【0028】
この時、下型枠3が所定の位置に正確に停止せずに下型枠3の端部が案内板30に接触しても、案内板30はコイルバネ28に抗して若干横移動可能として柔軟性を持たせているために破損に至ることはない。これによって案内シュート17の案内板30を下型枠3の端部位置まで望ませることができ、コンクリートを下型枠3の端部までスムーズに充填投入することができる。
【0029】
【発明の効果】
以上のように本発明の請求項1記載の案内シュートによれば、コンクリートホッパ2の下位に円筒状型枠を移送する移送装置4を配設し、該移送装置4にて移送する円筒状型枠の長手方向に沿って一対のカバー体18を対向させ、各カバー体18の下端部を前記円筒状型枠の内側縁部に当接可能なように各カバー体18の間隔を拡縮自在に、かつ昇降自在に配設する一方、カバー体18の内側には上端部を回動自在に軸着した案内板30を配設すると共に、案内板30の下端部前記円筒状型枠内の鉄筋かご5に当接させるようにコイルバネ32により内方向に弾力的に押圧付勢したので、型枠へのコンクリート充填時、カバー体18を型枠の内側縁部に当接させたうえ、案内板30を鉄筋かご5の中央部寄りに当接させることができ、投入したコンクリートを下型枠3の側縁部から漏洩するのを防止できると共に、コンクリートを鉄筋かご5の軸心付近に誘導投入することができて充填作業を効率よく行うことができる。
【0030】
また、本発明の請求項2記載の案内シュートによれば、案内板30における円筒状型枠の長手方向側の板幅をカバー体18における円筒状型枠の長手方向側の板幅より幅広く形成すると共に、案内板30の上端部とカバー体18の内側とを回動自在に軸着する棒状体26にコイルバネ28を介装して案内板30を弾力的に横移動可能に構成したので、型枠の端部をカバー体18に当接させて停止させることができ、型枠の端部付近へのコンクリートの充填を容易に行うことができる。

BACKGROUND OF THE INVENTION
The present invention relates to a guide chute for a concrete hopper for supplying and guiding a concrete concrete secondary product, for example, a concrete mold such as a concrete column and a concrete pile when the concrete is discharged from the concrete hopper and charged.
[0002]
[Prior art]
Concrete secondary products such as concrete pillars and concrete piles are filled with concrete in a cylindrical mold that can be divided into upper and lower parts, and are formed into a predetermined shape by centrifugal molding. When this concrete is filled, the concrete is guided into the mold by a guide chute. For example, as described in Japanese Utility Model Laid-Open No. 5-29707, a guide chute composed of a pair of rectangular plates is used. Some of them are made to face along the longitudinal direction of the mold, and the lower end thereof is brought into contact with the side portion of the reinforcing bar loaded in the mold.
[0003]
[Problems to be solved by the invention]
However, in the conventional method in which the guide chute is simply brought into contact with the side of the reinforcing steel basket in the formwork, if the guide chute is brought into contact with the center of the reinforcing steel basket near the center of the reinforcing steel bar, There is a risk that the concrete to be filled due to a gap between the lower end of the mold and the side edge of the mold will leak into the flange of the side edge of the mold.
[0004]
In addition, when the guide chute is moved closer to the side edge of the formwork to prevent leakage, concrete for secondary products with low fluidity with a slump value of 5 cm or less from the side of the rebar cage is placed in the rebar cage. It is difficult to insert, and concrete tends to accumulate between the side of the reinforcing bar and the guide plate. Even if a vibrator is attached to the guide chute as in the conventional example, a reduction in work efficiency during filling is inevitable.
[0005]
In addition, when filling concrete into a cylindrical formwork, it is common to move the formwork relative to the filling device. This cylindrical formwork is quite heavy, and it is difficult to stop it suddenly even if it stops at a predetermined position. Therefore, when filling concrete near the end of the formwork, the end of the formwork In many cases, the end of the mold is stopped before the guide chute so that it does not hit the guide chute provided below the filling device. In this way, the end of the formwork is stopped before the guide chute and is filled, so it is necessary to manually fill the end of the formwork with the concrete poured in front of the end of the formwork Therefore, the burden on the worker is large and the improvement of work efficiency is hindered.
[0006]
In the present invention, in view of the above points, when concrete is filled into a cylindrical formwork for a secondary product, the concrete is not leaked or accumulated on the side edge of the formwork, and the concrete is placed in the formwork. An object of the present invention is to provide a guide chute for a concrete hopper for a secondary product that can be filled smoothly.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a guide chute for a concrete hopper that feeds and guides a concrete chute filled with a concrete in a cylindrical form loaded with a rebar cage. in the previous SL arranged a transfer device for the lower transporting a cylindrical formwork to the concrete hopper, along the longitudinal direction of the cylindrical mold to transfer at said transfer device are opposed to the pair of cover members, each cover the spacing of the lower end portion of the body the cylindrical mold can abut so that each cover member to the inner edge of the expansion freely, and while vertically movably disposed, the upper end portion on the inside of each cover body A guide plate pivotally attached to the shaft is disposed, and the lower end portion of each guide plate is elastically pressed and urged inward by a spring body so as to abut on a rebar cage in the cylindrical mold . It is characterized by that.
[0008]
The width of the guide plate on the longitudinal side of the cylindrical mold is wider than the length of the cover on the longitudinal side of the cylindrical mold , and the upper end of the guide plate and the inside of the cover are rotated. It is characterized in that the guide plate can be elastically moved laterally by interposing a spring body on a rod-like body that is freely attached to the shaft .
[0009]
DETAILED DESCRIPTION OF THE INVENTION
According to the guide chute of the first aspect of the present invention, the guide plate is disposed inside the pair of cover bodies disposed along the longitudinal direction of the mold, and the guide plate is formed by the spring body. Since it is elastically biased toward the inside of the frame, when the lower end of the cover body is brought into contact with the inner edge of the mold frame, the lower end of the guide plate is located at a position away from the inside of the cover body. It will come into contact with the cage. As a result, when putting concrete into the formwork, the cover body closes the inner edge of the formwork, and the guide plate guides the concrete to the vicinity of the axis of the rebar cage. While preventing leakage, it can be filled mainly in the vicinity of the central portion of the reinforcing bar cage, and an efficient filling operation can be expected.
[0010]
According to the guide chute described in claim 2, even if the end of the moving mold is too close to the guide chute and comes into contact with the guide plate, the guide plate is moved sideways along the cover body by the elasticity of the spring body. It can absorb the impact to move and will not damage the guide chute. Therefore, the end of the formwork can be stopped by being brought very close to the guide chute, and the concrete can be filled near the end of the formwork.
[0011]

[0014]
Further, a support frame 6 is disposed at the upper part of the gantry 1, and sprockets 7 are pivotally supported by rotation shafts 8 at the four corners of the support frame 6. A rotating sprocket 9 is mounted, and a chain 12 is wound around the rotating sprocket 9 and a sprocket 11 attached to a driving motor 10, and the rotation of the driving motor 10 is rotated through the respective rotating shafts 8 at the four corners of the sprocket 7. To communicate.
[0015]
The chain 13 is wound around the sprockets 7 at the four corners, one end of the chain 13 is attached to a frame-like lifting frame 14 disposed below the support frame 6, and the other end is disposed on the side of the gantry 1. It is attached to a counterweight 15 that cancels the weight of the installed lifting frame 14, and the sprocket 7 is rotated forward and backward by forward and reverse rotation of the driving motor 10, so that the lifting frame 14 is moved up and down along the guide body 16. I have to.
[0016]
Reference numeral 17 denotes a guide chute for guiding the concrete in the concrete hopper 2 into the lower mold 3, and the guide chute 17 is a pair of squares having an appropriate length along the longitudinal direction of the lower mold 3 to be transferred. The cover body 18 is opposed to each other, and a lower end portion of the cover body 18 can be in contact with the inner edge portion of the lower mold 3.
[0017]
Further, nuts 19 are fixed to both sides of the upper end portion of the cover body 18, and the nuts 19 are screwed to screw rods 20 screwed in opposite directions, and both ends of the screw rods 20 are attached to the lifting frame 14. The screw rod 20 is rotated by a driving motor 23 attached to the lifting frame 14 via the rotating shaft 21 and the transmission gear 22 so that the space between the left and right cover bodies 18 can be expanded / reduced. It is like that.
[0018]
Further, a slide rail 24 is disposed on the upper surface of the lifting frame 14 in parallel with the screw rod 20, and a slide unit 25 that slides along the slide rail 24 is attached to the slide rail 24. Both sides of the upper end are attached to the slide unit 25 so that the screw rod 20 can be smoothly expanded and contracted.
[0019]
Also, as shown in FIGS. 4 and 5, a rod-like body 27 is fixed to the inside of the cover body 18 by a support piece 26, and a coil spring 28 that is a spring body and a moving piece 29 are attached to the rod-like body 27. The moving piece 29 can be moved left and right against the restoring force of the coil spring 28 mounted on both sides.
[0020]
An upper end portion of a guide plate 30 serving as a guide guide for concrete is fixed to the moving piece 29 so that the guide plate 30 can swing around the rod-shaped body 27, and at the same time against the restoring force of the coil spring 28. You can move horizontally. Further, the guide plate 30 is made wider than the cover body 18 so that even if the guide plate 30 moves laterally, the supplied concrete does not directly hit the cover body 18.
[0021]
Further, in order to bring the guide plate 30 into contact with the rebar cage 5 of the lower mold frame 3 which is elastically pressed and urged inwardly, the tip of the pressing member 31 penetrating the cover body 18 is guided to the guide plate 30. The guide plate 30 is configured to press and urge the guide plate 30 inward by a restoring force of a coil spring 32 that is a spring body attached to the pressing member 31.
[0022]
Therefore, when filling the concrete stored in the concrete hopper 2 into the lower mold 3, first, the drive motor 23 is driven so that the interval between the cover bodies 18 is slightly inside the inner edge of the lower mold 3. Then, the motor 10 is driven to rotate forward to raise the elevating frame 14, and the guide chute 17 is kept on standby.
[0023]
Then, the inside of the lower mold 3 loaded with the reinforcing bar 5 is sent to the lower part of the concrete hopper 2, and when the lower mold 3 reaches the lower part of the concrete hopper 2, the driving motor 10 is reversely rotated to lower the guide chute 17. Let
[0024]
Next, the drive motor 23 is rotated in the forward direction to move the cover body 18 in the direction in which the space between the cover bodies 18 is expanded, so that the lower end portion of the cover body 18 is brought into contact with the inner edge portion of the lower mold frame 3. At this time, the guide plate 30 disposed on the inner side of the cover body 18 is pressed and urged inward by the coil spring 32 so that the lower end of the guide plate 30 comes into contact with the rebar cage 5. Acts as a guide for guiding near the center.
[0025]
When the cover body 18 is fixed at a predetermined position, a predetermined amount of concrete is discharged from the concrete hopper 2 and guided to a guide plate 30 serving as a guide guide on the inner side of the cover body 18 to put the concrete in the lower mold 3. Fill.
[0026]
When a predetermined amount of concrete is filled in this way, the lower mold 3 is moved forward by a predetermined amount, and concrete is sequentially filled.
[0027]
Further, when the lower mold 3 is sequentially advanced and finally the concrete is filled in the vicinity of the end of the lower mold 3, the lower mold 3 is moved forward with the guide chute 17 lowered, and the lower mold 3 3 is stopped at a position where the end of 3 substantially contacts the end of the guide plate 30.
[0028]
At this time, even if the lower mold frame 3 does not accurately stop at a predetermined position and the end of the lower mold frame 3 contacts the guide plate 30, the guide plate 30 can be slightly moved laterally against the coil spring 28. Because it is flexible, it will not be damaged. As a result, the guide plate 30 of the guide chute 17 can be desired up to the end position of the lower mold 3, and the concrete can be filled and charged smoothly to the end of the lower mold 3.
[0029]
