〔産業上の利用分野〕
この発明は、コンクリートセグメントの製造方法に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for manufacturing concrete segments.
従来、コンクリートセグメントは、以下のようにして製
造されていた。即ち、型枠内にコンクリートを、型枠を
機械的に振動させながら打設し、次いで、型枠内のコン
クリートの上面を、これに、人がコンクリートの硬化時
期毎に数回、木鏝や金鏝を擦り付けて仕上げ、養蒸後、
脱型する。Conventionally, concrete segments have been manufactured as follows. That is, concrete is poured into a formwork while the formwork is mechanically vibrated, and then the upper surface of the concrete in the formwork is pounded with a wooden trowel or a handshake several times each time the concrete hardens. Finish by rubbing with a metal trowel, and after nourishing and steaming,
Remove the mold.
しかしながら、型枠内のコンクリートの上面を鏝によっ
て仕上げる作業は、重労働を強いられるので、型枠内の
コンクリートの上面仕上作業の軽減化を図ることができ
るコンクリートセグメントの製造方法の開発が望まれて
いるが、かかる方法は、まだ、提案されていない。However, finishing the top surface of the concrete inside the formwork with a trowel requires heavy labor, so it is desired to develop a method for manufacturing concrete segments that can reduce the work of finishing the top surface of the concrete inside the formwork. However, such a method has not yet been proposed.
従って、この発明の目的は、型枠内のコンクリートの上
面仕上作業の軽減化を図ることができるコンクリートセ
グメントの製造方法を提供することにある。Accordingly, an object of the present invention is to provide a method for manufacturing a concrete segment that can reduce the work required to finish the top surface of concrete within a formwork.

ある。This invention involves pouring concrete into a formwork while vibrating the formwork, then laying a net plate on the top surface of the poured concrete, then placing a trowel on top of the net plate, and The feature is that the trowel is moved along the upper surface of the concrete while vibrating the trowel.
次に、この発明のコンクリートセグメントの製造方法の
一実施態様を、図面を参照しながら説明する。Next, one embodiment of the concrete segment manufacturing method of the present invention will be described with reference to the drawings.

第１図に示すように、この発明のコンクリートセグメン
トの製造方法は、下記からなっている。As shown in FIG. 1, the method for manufacturing a concrete segment of the present invention consists of the following steps.
即ち、コンクリートセグメント用型枠１内にコンクリー
トを打設する。型枠ｌは、従来と同様にコンクリートが
型枠１内にまんべんなく行き渡るように機械的に振動さ

、型枠１に沿って自動的に移動させてもよい。この後は
、従来の、コンクリートセグメントの製造方法と同様に
、養魚後、脱型する。That is, concrete is poured into the concrete segment formwork 1. The formwork 1 is mechanically vibrated so that the concrete is evenly distributed within the formwork 1, as in the conventional case. When the concrete 2 is completely poured, a net plate 3 made of expanded metal, wire lath, metal lath, wire mesh, resin, rubber, etc. is laid on the top surface of the concrete 2. Next, #l! where an electric vibrator 4 was attached on the mesh plate 3! Put 5 on it. The tip of the trowel 5 is bent upward so that the trowel 5 does not get caught on the net plate 3 when moving the trowel 5. And jl! 5 along the formwork 1. The trowel 5 may be moved manually or automatically along the formwork 1. After this, the fish is cultured and then demolded in the same manner as in the conventional method for producing concrete segments.
コンクリート２の上面に、エキスバンドメタル等からな

クリート２の上面に形成されている凹部内の空気がスム
ーズに、網板３の網目から外部に抜は出て、コンクリー
ト２の上面が平滑化される。網板３は、型枠ｌのコンク
リート２のダレを防止する作用も有する。When a material made of expanded metal or the like is laid on the top surface of the concrete 2, and a vibrating trowel 5 is applied from above, the air in the recesses formed on the top surface of the concrete 2 is smoothly drawn from the mesh of the mesh plate 3 to the outside. The top surface of the concrete 2 is smoothed. The mesh plate 3 also has the function of preventing the concrete 2 in the formwork l from sagging.
網板３を敷かないで、鏝５をコンクリート２の上面にあ
てがうと、鏝５の振動によってコンクリート２の表面に
ダレや波打が生じて、表面性状に優れたコンクリートセ
グメントが得られない。If the trowel 5 is applied to the upper surface of the concrete 2 without laying the mesh plate 3, the vibration of the trowel 5 will cause sag or undulation on the surface of the concrete 2, making it impossible to obtain concrete segments with excellent surface properties.
鏝５を型枠ｌに沿って移動させたら、網板３をコンクリ
ート２の上面から取り外す。この際、コンクリート２の
上面に網板３の跡が残るが、これは、最終仕上工程で容
易に平滑に仕上げられる。After moving the trowel 5 along the formwork l, the net plate 3 is removed from the upper surface of the concrete 2. At this time, traces of the net plate 3 remain on the upper surface of the concrete 2, but this can be easily smoothed out in the final finishing step.
以上説明したように、この発明によれば、従来のように
、コンクリートの上面を、作業者がこれに直に鏝を擦り
付けて仕上げる必要がないので、型枠内のコンクリート
の上面仕上作業が大幅に軽減されるといった有用な効果
がもたらされる。As explained above, according to the present invention, there is no need for the worker to finish the top surface of the concrete by directly rubbing a trowel on it as in the past, so the work of finishing the top surface of the concrete inside the formwork is greatly simplified. This has the beneficial effect of reducing the
