More specifically, the present invention relates to a belt-type centrifugal force pillar forming apparatus that can form centrifugal force pillars under high-speed conditions.

In a centrifugal force column forming machine, it is necessary to produce centrifugally formed concrete columnar products of various diameters and lengths using the same equipment. In order to obtain such a centrifugally formed columnar product made of concrete, a belt-type centrifugal force column forming apparatus using a plurality of flat belts in parallel has been proposed.
The pulley in this conventional belt-type centrifugal force column making device had a diameter of 30 cm to 80 cm and had a flat circumferential surface over its entire width.

直接型枠を乗せる方式であるベルトを使用しない
方式の昔からの遠心力製柱機における最高速度で
ある35G程度（すなわち、平ベルトの周速度が
350ｍ／分程度）として使用するときは問題なく
使用できた。 In this conventional belt-type centrifugal force column making device, the centrifugal force applied to the concrete, which is the forming material used to make the column, is transferred to a belt that places the formwork directly between wheels rotating in the same direction at parallel positions. The maximum speed of the old centrifugal force column making machine that does not use the method is about 35G (in other words, the circumferential speed of the flat belt is
When used at a speed of approximately 350 m/min), it was possible to use it without any problems.

で、従来の平ベルトを複数本並列に使用する遠心
力製柱装置では、成形材料にかける遠心力を最高
でも30G〜35G程度に抑えて使用していた。 However, in order to apply a centrifugal force of 35G or more, for example 45G, the circumferential speed of the flat belt should be increased to 500m/
If the length exceeds about 10 minutes, a meandering phenomenon will occur where the flat belt moves left and right in the pulley axis direction on the pulley circumferential surface, even if the column formwork filled with concrete, which is the forming material, is placed on top of the flat belt. easy. If a meandering phenomenon occurs, the flat belt may come off the pulley, so in conventional centrifugal force column forming equipment that uses multiple flat belts in parallel, the centrifugal force applied to the molding material is limited to about 30G to 35G at most. I was using it.
そこで、蛇行により平ベルトがプーリから外れ
ることを防止するために、プーリ周面の側端に径
方向に張出し、プーリ周方向に連続した鍔を設け
たプーリを使用したベルト式遠心力製柱装置が考
え出されている。 Therefore, in order to prevent the flat belt from coming off the pulley due to meandering, a belt-type centrifugal force column making device using a pulley with a flange extending radially from the side end of the pulley circumferential surface and continuous in the circumferential direction of the pulley. has been devised.

However, the belt-type centrifugal force forming column device, which has a collar on the pulley side end to prevent the flat belt from meandering, can be operated at high speeds and can considerably prevent the flat belt from coming off the pulley; This causes the flat belt and the collar to rub against each other, causing the side edges of the flat belt to easily wear out, and the life of the flat belt to be extremely shortened. Furthermore, if the molding material is rotated at an extremely high speed so that the centrifugal force applied to it is about 45G (i.e., when the circumferential speed of the flat belt is about 500 m/min), even if there is a collar, the flat belt will ride on the collar. However, there was a drawback that there was a risk that the flat belt would come off.

However, the pulley width W is approximately 1.2 to 2 times the width S of the flat belt, and the width w of the parallel portion 14 is 1/30 to 1/20 of the pulley width W, and the pulley peripheral surface is approximately 1.2 to 2 times the width S of the flat belt.

The portion 15 is continuous with the horizontal portion 14. In this way, a crown is provided on the pulley peripheral surface.

うに形成されている。 In the device of this invention, the pulley width W is about 1.2 to 2 times (preferably 2.0 times) the width S of the flat belt 11.
), the width w of the parallel part 14 is 1/30 to 1/2 of the pulley width W
0, the crown amount h expressed by the difference between the radius of the center of the pulley and the radius of the end of the pulley, which is the maximum diameter part of the pulley, is formed to be 1/125 to 1/100 of the maximum diameter D of the pulley.
以下に前記のプーリ幅Ｗとベルト幅Ｓと平行部
幅ｗの数値範囲内と範囲外での効果の比較を行つ
た試験例を示す。 Below is a test example in which the effects of the above-mentioned pulley width W, belt width S, and parallel portion width W within and outside the numerical ranges were compared.

製柱するという実験を10回繰り返した。 First, in the apparatus shown in FIGS. 1 and 2, the maximum diameter D of the pulley is 30 cm, the pulley width W is set to be twice the belt width S, and the crown amount h is set to 1/1/2 of the maximum diameter. 100, the width w of the parallel part was changed, and an experiment was repeated 10 times to make a pile with a diameter of 300 mm and a length of 6 m at a circumferential belt speed of 500 m/min.
その結果、平行部の幅ｗがプーリ幅Ｗの1/18の
ときは、10回の試験中２回、製柱の途中でどちら
か一方側のベルトがプーリから外れそうになつた
ので、途中で製柱を中止せざるを得なかつた。 As a result, when the width w of the parallel part was 1/18 of the pulley width W, the belt on either side almost came off the pulley during pillar making in two out of 10 tests. We had no choice but to stop making pillars.
また、平行部の幅ｗがプーリ幅Ｗの1/35のとき

方側のベルトが破損しそうになり、やはり途中で
製柱を中止せざるを得なかつた。 Also, when the width w of the parallel part is 1/35 of the pulley width W, one of the belts on either side was about to break during the pillar making process, and once out of 10 tests, the belt on either side was about to break during the pillar making process. I had no choice but to cancel it.
しかし、平行部の幅ｗがプーリ幅Ｗの1/20〜1/
３０のときは何らトラブルを発生することなく製柱
できた。 However, the width w of the parallel part is 1/20 to 1/2 of the pulley width W.
When I was 30, I was able to make pillars without any trouble.
なお、ベルトの周速を下げて、従来ベルト式の

く製柱できた。 In addition, the circumferential speed of the belt has been lowered to 350 m/s, which is the circumferential speed used in conventional belt-type centrifugal column making equipment.
If the width w of the parallel part is 1/ of the pulley width W
I was able to make pillars with both 18 and 1/35 without any trouble.
次いで、プーリ幅Ｗがベルト幅Ｓの２倍と一定

直径Ｄが80cmとしたプーリを使用してクラウン量
ｈを種々変化させて直径が800mm、長さが６ｍの
パイルをベルトの周速を500ｍ／分とした条件で
製柱するという実験を10回繰り返した。 Next, the pulley width W was kept constant at twice the belt width S, the width w of the parallel part was kept constant at 1/25, the maximum diameter D was 80 cm, and the crown amount h was varied. An experiment was repeated 10 times in which a pile with a diameter of 800 mm and a length of 6 m was made at a circumferential belt speed of 500 m/min.
クラウン量ｈが1/90のときは10回の試験中少な

を得なかつた。 When the crown amount h was 1/90, at least once out of 10 tests, one of the belts on either side almost broke during pillar making, and pillar making had to be stopped midway.
クラウン量ｈが1/130のときは10回の試験中２

止せざるを得なかつた。 When crown amount h is 1/130, 2 out of 10 tests
During the process, one of the belts on either side came close to coming off the pulley, so they had no choice but to stop the process.
しかし、クラウン量ｈが1/100〜1/125のとき

遠心力製柱装置で使用されていた周速の350ｍ／
分とした場合は、クラウン量ｈが1/90でも1/130

た。 In addition, the circumferential speed of the belt has been reduced to 350 m/cm, which is the circumferential speed used in conventional belt-type centrifugal force column forming equipment.
When expressed in minutes, even if the crown amount h is 1/90, it is 1/130.
However, I was able to make the pillars without any problems.

回繰り返した。 Finally, the width w of the parallel part is kept constant at 1/25, the crown amount h is kept constant at 1/100, and the maximum diameter D is 30 cm.
Using the pulley, change the width W of the pulley,
A pile with a diameter of 300 mm and a length of 6 m is
10 experiments were carried out in which pillars were made at a speed of 500 m/min.

止せざるを得なかつた。 When the pulley width W was 1 times the belt width S, and when it was 2.2 times the belt width S, at least once out of 10 tests, the belt on either side seemed to come off the pulley during pillar making. Due to the summer weather, we had no choice but to stop making pillars midway through.
しかし、プーリの幅Ｗがベルト幅Ｓの1.2倍〜
2.0倍のときは何らトラブルを発生することなく
製柱できた。 However, the pulley width W is 1.2 times the belt width S.
At 2.0x, pillars could be made without any trouble.

することなく製柱できた。 In addition, the circumferential speed of the belt has been reduced to 350 m/cm, which is the circumferential speed used in conventional belt-type centrifugal force column forming equipment.
If the width of the pulley is W, then the width of the belt is S.
Whether it was 1.2x or 2.0x, pillars could be made without any trouble.

従つて、上記の範囲を外れるプーリを使用する場
合は、成形材料にかける遠心力を従来のベルト式
製柱装置と同様に35G程度（すなわち、ベルトの
周速を350ｍ／分程度）に下げて製柱しなければ
ならなくなる。 In this way, this is the first attempt to rotate at a higher speed than the speed commonly used with conventional belt-type column making machines.When used, the pulley width W, parallel part width w, and crown amount h can be controlled within a certain range. If you don't
Problems arise in which the belt on either side is damaged or comes off, making it difficult to form piles at a high speed that has never been done before.
Therefore, when using a pulley that is outside the above range, the centrifugal force applied to the molding material should be lowered to about 35G (i.e., the circumferential speed of the belt should be about 350 m/min), as with conventional belt-type column forming equipment. Pillars will have to be made.
なお、この考案に使用するより具体的な値とし
ては、プーリ幅Ｗは150〜800mm、平行部の幅ｗは
５〜40mm、クラウン量ｈは3.00mm〜8.00mmの範囲
である。 In addition, as more specific values used in this invention, the pulley width W is in the range of 150 to 800 mm, the width of the parallel portion w is in the range of 5 to 40 mm, and the crown amount h is in the range of 3.00 mm to 8.00 mm.

上するという優れた効果を発揮する。 Using this particular pulley of this invention in this way,
Centrifugal force column making equipment uses multiple flat belts in parallel, and even if the flat belts are rotated at extremely high speeds of around 500 m/min, which was previously unimaginable, to make piles, the flat belts may come off or be damaged. It has the excellent effect of making it possible to make pillars in a stable state without any problems and reducing wear on the belt.It also enables high-speed pillar making, which has the effect and advantage of shortening the pile manufacturing time. This has the excellent effect of improving the quality of the piles.

When the pulley 9 is rotated by the drive device 8 via the rotating shaft 1, the pulleys 10 and 11 are rotated by the flat belt 12.
The column forming form 13 is rotated while being supported by the flat belt 12 between the pulleys 9 and 10. For this reason, centrifugal force forming is possible, but during this work, the flat belt 12 is connected to the pulley 9 of a specific shape,
The product rotates with the pulleys 9, 10, 11 and moves left and right in the axial direction of the pulley due to the frictional force applied to the circumferential surface of the pulleys 10 and 11, but the product can be of any diameter or length. Even when making columns, the flat belt 12 will not come off from the pulleys 9, 10, 11 of a specific shape.

９，１０，１１から外れることはない。 In addition, the flat belt 12 has a specific crown structure around the pulleys 9, 10, and 11 around which it is wound, so that the flat belt is always attached to each pulley even when making a column of a product of any diameter or length. The tension is large at the center of the belt and small at both sides. Therefore, when the flat belt 12 is fitted to each pulley and deviates to one side on the circumferential surface of the pulley, the tension acting on that one side becomes smaller, but the tension acting on the other side increases. A force that reduces the tension and returns to the other side acts on the other side, and the flat belt 12 returns in the opposite direction on the pulley circumferential surface. For this reason, when manufacturing a product of any diameter or length, the flat belt 12 is always kept hanging on the parallel part 14 of the pulley circumferential surface, and does not come off the pulleys 9, 10, 11. do not have.
さらに、この特定された大きさの平行部の存在
は平ベルト１２の片寄りからの戻りを早くする役
割を果たしている。 Furthermore, the presence of the parallel portion of the specified size plays a role in speeding up the return of the flat belt 12 from one side.

平ベルト１２の周速を同一に保つことができる。 In other words, even if a single molding frame is stretched over multiple flat belts 12 and rotated at high speed in a centrifugal column forming device, a parallel portion of a specified size will still exist in the center of the pulley. This ensures that the tension of the plurality of flat belts 12 used is always maintained at a constant constant tension state, and that the flat belts 12 peripheral speeds can be kept the same.

As mentioned above, the centrifugal force pillar making device of this invention, which uses multiple flat belts using specially shaped pulleys in parallel, can handle multiple flat belts when making pillars of products of any diameter or length. It becomes possible to maintain the tension of belt 12 at a stable constant tension state and to keep the peripheral speed of flat belt 12 the same.
It becomes possible to rotate the flat belt at high speed in a safe state. In other words, in a centrifugal column making device that uses a flat belt, when making columns of any diameter or length, for example, the circumferential speed of the flat belt is increased to 500 m/min or more, and the Even if the centrifugal force applied to the molding material is 45G or more, it is possible to form pillars in a stable state, and the wear of the flat belt is also reduced.

There is also less wear and tear on the equipment.
