【産業上の利用分野】[Industrial applications]

本考案は、バラツキのない常に一定均一のコンクリート製品を成形す るためのコンクリート練り混ぜと締固め状態を測定するコンクリートの 練り加減測定器に関する。 The present invention relates to a concrete kneading degree measuring device for measuring concrete kneading and compaction conditions for molding a constant and uniform concrete product without variation.

【0002】[0002]

【従来の技術】[Prior art]

従来超硬練りコンクリートのミキサーでの混練は砂、砂利の粒度、特 に細い砂、荒い砂の粒度の違いで含水量に差があって水分調整装置にて 水分比の測定を行っていても、成形機で成形し易く練り混ぜられたコン クリートや成形困難に練り混ぜられた水分変化のある硬練りコンクリー ートが供給されているため製品にバラツキが生じていた。 Conventionally, when mixing cemented carbide with a mixer, there is a difference in the water content due to the difference in the particle size of sand, gravel, especially fine sand, and coarse sand. However, there were variations in the product due to the supply of concrete that was easily mixed by a molding machine and kneaded for mixing, and hard kneaded concrete that was mixed for difficult molding and had a change in water content.

【0003】 したがって、超硬練りコンクリートの混練はきわめて難かしく、従来 はvebe試験あるいは練り混ぜたコンクリートを手で握って確かめる 経験的な方法等でチェックを行っていたがいずれも正確さに欠けた測定 方法であった。またこの硬練りコンクリートの測定は迅速且つ簡単であ って正確に行うものでないと役に立たないとされている。そして、即時 脱型で成形する製品の優劣は硬練りコンクリートの練り混ぜ状態で決ま るといっても過言ではないといわれていて、この超硬練りコンクリート の練り混ぜチェックは工程管理として毎日2回行うように規定されてい る。Therefore, it is extremely difficult to knead super-hard mixed concrete, and conventionally, the vebe test or the empirical method of grasping the kneaded concrete with a hand to check it was checked, but none of them was accurate. It was a measurement method. Moreover, it is said that the measurement of this hard-mixed concrete is not useful unless it is done quickly and easily and accurately. It is said that it is not an exaggeration to say that the superiority or inferiority of products molded by immediate demolding depends on the mixing state of hard concrete, and this mixing check of ultra-hard concrete is performed twice a day as process control. It is stipulated to do.

【0004】[0004]

【考案が解決しようとする課題】[Problems to be solved by the device]

このようにミキサーでの混練時に水分調整しても実際現状では成形機 に供給される硬練りコンクリートの練り加減は固い練りのコンクリート もあれば軟かい練りのコンクリートもあり、これが成形機に供給される ため成形が不調となって製品にもバラツキが生じて均一な製品が製造で きない。 Even if the water content is adjusted during kneading with a mixer in this way, in reality, there are some types of hard kneading concrete that are supplied to the molding machine, such as hard kneading concrete and soft kneading concrete, which are supplied to the molding machine. As a result, the molding will become unsuccessful and the products will also vary, making it impossible to manufacture uniform products.

【課題を解決するための手段】[Means for Solving the Problems]

考案者は、このような超硬練りコンクリートの練り混ぜと締固めの測 定が困難な点を解決するため鋭意研究の結果考案に到達したものであっ て、本考案は、ミキサーで混練した超硬練りコンクリートを取外し自在 の測定用の試験筒体に取出して詰め、この筒体を上下動する底板に載置 して、この底板に軸体を設けて偏心カムに当接させる一方、試験筒体に 納めたコンクリート上面に重錘押圧板を設け、この押圧板の上面に規定 目盛を有する軸を装着してコンクリート入りの試験筒体を偏心カムに設 けたL形状の切込みによって垂直落下させ、この衝撃と上方の重錘押圧 板の押圧で試験筒内のコンクリートの沈降を目盛で測定して練り加減を 計るものである。 The inventor arrived at the idea as a result of diligent research in order to solve the problem that it is difficult to measure the mixing and compaction of such superhard concrete, and the present invention was made by mixing the super-mixed concrete with a mixer. Remove the hard concrete into a removable test cylinder for measurement, place it on a bottom plate that moves up and down, and install a shaft on this bottom plate to make it contact the eccentric cam. A weight pressing plate is provided on the concrete upper surface of the body, a shaft having a specified scale is mounted on the upper surface of the pressing plate, and the test cylinder containing concrete is vertically dropped by the L-shaped notch provided on the eccentric cam. With this impact and the pressing of the weight pressing plate above, the sedimentation of concrete in the test tube is measured on a scale to measure the degree of mixing.

【0006】[0006]

【作用】[Action]

この測定は、正常なコンクリートの練り加減によって測定した目盛を 基準として、次に測定するミキサー内の練り上ったコンクリートを採取 して試験筒内に充填して同様に試験を行い、基準測定した目盛と比較し て許容誤差内ならばよいが、変化している場合は練り混ぜの水分調整を 行って練り加減の統一を図りミキサーから成形機に供給するものである 。 This measurement is based on the scale measured by adjusting the normal mixing of the concrete, and the concrete that has been thoroughly mixed in the mixer to be measured next is sampled and filled in the test tube, and the same test is performed to make the standard measurement. It should be within the permissible error compared to the scale, but if it is changing, the water content of the kneading should be adjusted to unify the kneading amount and be supplied from the mixer to the molding machine.

【0007】 この練り混ぜの測定はミキサーで混練した練り上った超硬練りコンク リートを迅速且つ確実に行ってこそその効果は大であり、本考案はミキ サーでの混練中に簡単に行えるためその作用効果は更に増大する。The measurement of this kneading has a great effect only when the kneaded cemented kneading concrete which has been kneaded with a mixer is swiftly and surely provided, and the present invention can be easily carried out during kneading with a mixer. Therefore, the action and effect are further increased.

However, the eccentric cam (8) has an L-shaped notch (9). When the vertical shaft (5), which is large and is in contact with the rotation of the eccentric cam (8), reaches the L-shaped notch (9), it vertically drops. Then, the concrete in the test tube (2) sinks due to the impact caused by the vertical drop. The sedimentation action of this concrete will be described in detail with reference to FIG. Although the eccentric cam (8) is manually rotated by the handle (10) in the drawing, it is of course possible to electrically rotate the eccentric cam (8) instead of the manual operation.

It is inserted in and is pulled out at the time of measurement to make the shaft (14) free. (18) is a graduated shaft (14) collar that can be moved up and down, and is fixed to the shaft (14) with a set screw (19) so that the amount of concrete can be adjusted to the optimum state.

The lower side is rotatably mounted on the test cylinder mounting plate (4) by a shaft pin (23). A nut (22) is provided on the upper portion of the bolt (21) to screw the lid (12) on the upper portion of the test cylinder (2). (24) shows a roll pin for stopping the operation of opening the tightening bolt (21) at a certain position by loosening the tightening nut (22) of the test tube (2) from the mounting plate (4). .

【0012】 本考案の測定器は上述の如きであるが、図3以下において試験筒(2 )の脱着の操作および測定の手段を順を追って説明する。Although the measuring instrument of the present invention is as described above, the operation of attaching and detaching the test tube (2) and the measuring means will be described in order with reference to FIG.

In FIG. 3, the test tube (2) is loosened by the tightening nut (22) and the bolt (21) is opened left and right. FIG. 4 is a front view showing a removed state, and FIG. 4 shows a state diagram in which the removed test tube (2) is separated from the upper lid body (12). Further, FIG. 5 shows a state diagram in which the separated test cylinder (2) is filled with concrete C kneaded with a mixer. Reference numeral (3-1) in the figure is a hole for mounting the test tube (2) at a proper position, and is fitted to the protrusion (4-1) provided at the center of the mounting plate (4). .

【0014】 このようにコンクリートCを充填した試験筒(2)は図6で示すよう に蓋体(12)を取付けて載置板(4)上に配されてボルト(21)に よって固定されて試験が開始される。As shown in FIG. 6, the test cylinder (2) thus filled with concrete C is mounted on the mounting plate (4) with the lid (12) attached and fixed by the bolts (21). The test is started.

【0015】 図7、図8、図9によって偏心カム(8)とこれに当接している軸( 5)の作用を順に説明すると、図6によってコンクリートCを充填した 試験筒(2)を配置したとき、載置板(4)に設けてある上下動する軸 (5)は図7に示されるように偏心カム(8)の最も低い位置に当接し ている。先ず上方の固定ピン(16)を抜いてフリーの状態とし、そし て偏心カム(8)をハンドル(10)を矢印のように操作して回転させ ると、軸(5)は偏心カム(8)の最高位置まで達してこれによって試 験筒(2)を最高位まで上昇する。(図8参照のこと)そして更に偏心 カムを回転させることによって、軸(5)は偏心カムのL形状の切欠き (9)の位置に達して図9に示すように一気に落下する。The operation of the eccentric cam (8) and the shaft (5) in contact with the eccentric cam (8) will be described in order with reference to FIGS. 7, 8 and 9, and a test cylinder (2) filled with concrete C will be arranged according to FIG. At this time, the vertically moving shaft (5) provided on the mounting plate (4) is in contact with the lowest position of the eccentric cam (8) as shown in FIG. First, the upper fixing pin (16) is pulled out to be in a free state, and the eccentric cam (8) is rotated by operating the handle (10) as shown by the arrow, so that the shaft (5) is rotated. ) To the highest position, which raises the test tube (2) to the highest position. (See FIG. 8) Then, by further rotating the eccentric cam, the shaft (5) reaches the position of the L-shaped notch (9) of the eccentric cam and falls at a dash as shown in FIG.

【0016】 したがって試験筒(2)内のコンクリートはこの衝撃と上蓋に設けら れている重錘押圧板(15)の押圧によって沈降するもので、この沈降 の度合を重錘押板(15)上面の目盛(13)によって測定してコンク リートの水分比、即ち練り加減を計るものである。Therefore, the concrete in the test tube (2) is settled by this impact and the pressure of the weight pressing plate (15) provided on the upper lid, and the degree of this settling is determined by the weight pressing plate (15). The water content of the concrete, that is, the degree of kneading is measured by measuring the scale (13) on the upper surface.

【0017】 図10乃至図14は偏心カム(8)の種々の形状を表わした図であっ て、図10は先の実施例で示した形状の偏心カムであってL形状の切欠 き(9)が一箇所に設けた形状であって、偏心カム(8)が一回転する 毎に一回の衝撃が与えられる。また図11はL形状の切欠きが(9)お よび(9−1)と二箇所設けてあって、偏心カム(8)が一回転する毎 に二回の衝撃が試験筒(2)に与えられる。同様に図12はL形状の切 欠きが(9),(9−1),(9−2)と三箇所設けてあり、さらに図 13は(9),(9−1),(9−2),(9−3)と四箇所設けてあ る。FIGS. 10 to 14 are views showing various shapes of the eccentric cam (8), and FIG. 10 shows the eccentric cam having the shape shown in the previous embodiment and having an L-shaped notch (9). ) Is provided in one place, and an impact is given each time the eccentric cam (8) makes one rotation. Further, in FIG. 11, L-shaped notches are provided at two locations (9) and (9-1), and each time the eccentric cam (8) makes one rotation, two impacts are applied to the test tube (2). Given. Similarly, FIG. 12 shows three L-shaped notches (9), (9-1) and (9-2), and FIG. 13 shows (9), (9-1) and (9-). 2) and (9-3) are provided at four locations.

【0018】 この偏心カムの形状は任意であってコンクリートの練り混ぜの状態に 応じて選択でき、超硬練りのコンクリートからスランプ大のコンクリー トまで試験測定に最も適したカムを用いることができる。またL形状の 切欠き(9)による試験筒(2)の落下距離も任意に形成することがで きる。The shape of this eccentric cam is arbitrary and can be selected according to the state of mixing of concrete, and a cam most suitable for test measurement can be used from concrete of superhard mixing to concrete of slump size. Further, the drop distance of the test tube (2) due to the L-shaped notch (9) can be arbitrarily formed.

【0019】 本考案においては、偏心カム(8)のL形状の切欠きによる落下衝撃 と上方重錘押圧板(15)の相方の作用によってコンクリートの練り混 ぜを測定しているが、スランプ大のコンクリートの場合は、偏心カム( 8)を用いず、試験筒(2)を載置する上下動板(4)から上の装置を テーブル振動機の上に載せてテーブル振動と上方の重錘押圧板(15) の押圧作用によって試験筒(2)内のコンクリートの沈降によって練り 混ぜ加減を測定することも可能である。In the present invention, the mixing and mixing of concrete is measured by the drop impact due to the L-shaped notch of the eccentric cam (8) and the mutual action of the upper weight pressing plate (15). In the case of the concrete, the eccentric cam (8) is not used, the device above the vertical moving plate (4) on which the test tube (2) is placed is placed on the table vibrator, and the table vibration and the upper weight are placed. It is also possible to measure the mixing degree by the sedimentation of the concrete in the test tube (2) by the pressing action of the pressing plate (15).

【考案の効果】[Effect of device]

以上従来からコンクリートの練り混ぜと締固め状態を試験測定する測 定機がなく、それぞれ経験に頼って手で握って見てその度合を確かめて いた。特に超硬練りのバサバサ状のコンクリートの練り混ぜと締固め状 態を迅速且つ正確に行うことはきわめて難かしかったが、本考案の測定 器によるときは簡単に正確にコンクリートの練り混ぜ締固め状態が測定 できるため、成形されるコンクリート製品にバラツキが生じることなく 常に均質の製品が成形できるという画期的な作用効果を奏するものであ る。 As mentioned above, there has been no measuring instrument to test and measure the mixing and compaction state of concrete so far, and each one had to rely on his experience to grasp it with his hand. In particular, it was extremely difficult to quickly and accurately perform the mixing and compaction of super-hard, dry, and dry concrete, but when using the measuring instrument of the present invention, it is possible to easily and accurately mix and compact concrete. Since the condition can be measured, this has the epoch-making effect that a homogeneous concrete product can always be molded without variation in the concrete product being molded.
