Abstract

PROBLEM TO BE SOLVED: To provide a manufacturing method that causes few variation of size and hardness of necessary locations even if an error of a material supply amount is caused in simultaneous molding of many pieces of the concrete spacer block.SOLUTION: A pressure plate 6 that pressurizes an upper surface of a spacer block is divided into a reinforcement steel receiving part 8 of a center part and shoulders part 9 on both sides, and are made to be pressurized by providing the pressure difference between the center part and the shoulder part. Pressurizing of a spacer block shoulder part 2 is enabled corresponding to the variation of the amount at the material supply while the pressure plate shoulder part 9 slides by the pressure lower than the reinforcement receiving part 8.

Description

本発明は外溝工事基礎部分の鉄筋受けに使用するコンクリートスペーサーブロックの製造方法に関する。  The present invention relates to a method for manufacturing a concrete spacer block used for reinforcing bar reception of an outer groove construction foundation.

近年普及してきたコンクリートスペーサーブロックは鉄筋のずれ止め溝を設けてあるため、従来のコンクリートスペーサーブロックに比べて利点が多い。  The concrete spacer block that has been popular in recent years has many advantages over the conventional concrete spacer block because it is provided with a groove to prevent the rebar from shifting.

しかしながら、近年多発する地震、地盤沈下等の対策の一環として基礎のより強化のため、その中心的役割を鉄筋と共に果たすコンクリートスペーサーブロック（以下、スペーサーブロックという）にも今まで以上に強度を求める声が強くなっている。  However, in order to strengthen the foundations as part of countermeasures against earthquakes and land subsidence that have occurred frequently in recent years, concrete spacer blocks (hereinafter referred to as spacer blocks), which play a central role with reinforcing bars, demand more strength than ever. Is getting stronger.

又、従来の生産性を上げるためのプレス機による多数個を同時加圧、即時脱型による製造方法では、多数個の型枠内に材料の均等な投入が極めて難しく、その結果硬度や寸法にばらつきが発生する欠点がある。  In addition, in the conventional manufacturing method by simultaneous pressurization and immediate demolding with a press machine to increase productivity, it is extremely difficult to evenly put materials into a large number of molds, resulting in hardness and dimensions. There is a drawback that variation occurs.

本発明は、スペーサーブロックの上面を加圧する加圧板を中心部の鉄筋受部と両側の肩部に分割し、中心部と肩部に圧力差を設けて加圧することにより上記課題を解決する。  The present invention solves the above problem by dividing a pressure plate for pressing the upper surface of the spacer block into a reinforcing bar receiving portion at the center and shoulders on both sides, and applying a pressure difference between the center and the shoulder.

本発明は、加圧面を鉄筋受部と肩部に分けることにより最重要な鉄筋受部の寸法、硬度は維持しながら、給材時の分量誤差はあまり寸法精度を必要としない肩部の寸法を若干のばらつきを持たせることにより、多数個取りの製品であっても鉄筋受部の寸法、硬度を維持したスペーサーブロックを提供することができる。  The present invention divides the pressing surface into a reinforcing bar receiving part and a shoulder part, while maintaining the most important dimensions and hardness of the reinforcing bar receiving part, the quantity error during feeding does not require much dimensional accuracy. By providing a slight variation, it is possible to provide a spacer block that maintains the size and hardness of the reinforcing bar receiving portion even in a multi-cavity product.

本発明のスペーサーブロックの製造方法では図４で示されるように図３の一体型加圧板６を鉄筋受部８と肩部９とに分割している。  In the spacer block manufacturing method of the present invention, as shown in FIG. 4, the integrated pressure plate 6 of FIG. 3 is divided into a reinforcing bar receiving portion 8 and a shoulder portion 9.

又、図４で示すように分割された加圧板の鉄筋受部８はプレスシリンダー５に直結されてあり、その両側を加圧板肩部９が鉄筋受部８より低い圧力でスライドしながら給材時の分量のばらつきに対応してスペーサーブロック肩部２の加圧を行うことができる。  Further, as shown in FIG. 4, the rebar receiving portion 8 of the divided pressure plate is directly connected to the press cylinder 5, and the pressure plate shoulder portion 9 slides on both sides thereof at a lower pressure than the rebar receiving portion 8. The spacer block shoulder 2 can be pressurized corresponding to the variation in the amount of time.

本発明は、加圧板肩部９をプレスシリンダー５に直結し鉄筋受部８をスライドさせる加圧板の動きが逆の製造方法でも外周の寸法精度が必要な製品には応用することが可能である。  The present invention can be applied to a product that requires outer dimensional accuracy even in a manufacturing method in which the pressure plate shoulder portion 9 is directly connected to the press cylinder 5 and the rebar receiving portion 8 is slid to move the pressure plate. .
