Description

Concrete Pole Making Equipment with Improved Spheres and Horses

The present invention relates to an apparatus for manufacturing a concrete pole pole and an improved concrete pole pole, and a method for manufacturing a pole pole using the same, and a structure to compensate for the shortage of concrete mortar on the horse sphere caused by the compaction by centrifugal force, and one conventional circle. Unlike spherical plates, the present invention relates to a structure that facilitates assembly and disassembly work by dividing weight while dividing into two spherical tension plates and spherical support plates.

In addition, the tension hinge bolts are inserted into the insertion grooves on the spherical side and the spherical side to fix both ends of the tension muscle, and the direction of the tension hinge bolts coincides with the placement direction of the tension muscle. It relates to a structure that minimizes the loss.

In addition, the present invention relates to a conventional concept in which the sphere side is the fixed side, the horseshoe side is the tension side, and the new concept in which the spheres are the tension side and the horseshoe side is the fixed side.

The production of electric pole is efficient and economical because there is no need for the subsequent process to reinforce the thickness of the finished concrete pole by inputting the lack of concrete mortar on the horse end to the design thickness.

In addition, since the present invention is divided into two circular tension plate and a circular support plate, the weight of the present invention is divided into two circular tension plates and a circular support plate, so that the handling is easy and the assembly and disassembly work is efficient, and the assembly structure is stable. It is a useful technique in the field of production technology.

In addition, there is a mortar inlet on the horse's side and a circular hole on the side of the sphere, respectively, so that steam is evenly contacted inside the hollow through the mortar inlet and the circular hole during steam curing. It is a useful technology that greatly saves the energy required for curing.

Jeonju is a concrete product with a tension bar inserted. Tensile force is applied to the tensile muscles.

Jeonju's shape is usually called the base buried in the basement and the opposite air side.

The inside of the pole is hollowed out. The diameter of the sphere is large, and the diameter of the sphere is small.

This is because the sphere is buried underground and is standing vertically, so the diameter of the sphere is large and the diameter of the sphere is small to be structurally stable.

Concrete pole is manufactured by centrifugal force.

The outline of concrete pole making is as follows.

In the Jeonju Mold, the tensile muscles are long and extended over the sphere and the horse sphere.

Tensile muscles are located between the sphere of the finished concrete pole and the concrete thickness of the sphere.

Since the diameter of the sphere is smaller than that of the sphere, it is more difficult for the reinforcement of the tensile muscle than the sphere.

The tensile force is applied to the tension muscles by the tension device, and concrete mortar is introduced into the mold in this state. At this time, the slump of concrete mortar is zero.

Centrifugal force is applied to the mold.

The concrete mortar adheres to the mold by centrifugal force, and a hollow part thereof is formed at the center thereof.

The concrete thickness of the sphere and the horse sphere in which the hollow part is formed is the same.

The central axis of centrifugal force is the central axis of the sphere and the horse sphere. The central axis of the centrifugal force is the central axis of the mold and its central axis is a horizontal line.

Since the central axis of the centrifugal force of the mold is a horizontal line, the bottom of the sphere is located below the bottom of the sphere. The concrete mortar of the mold is gravity-driven from the top side to the bottom side. This is because the pole is inclined downward from the end to the sphere.

The slope of the pole is usually 1/75 with respect to the central axis.

The central axis of the centrifugal force is a horizontal line connecting the central axis of the sphere and the sphere, and since the concrete thickness of the sphere and the sphere is the same, the concrete mortar of the sphere side in the mold is directed to the sphere side by gravity due to the slope of the pole.

It is for this reason that the slump of concrete mortar is set to 0 to minimize the amount of deflection. Even if the slump value = 0, the concrete mortar is not compacted.

As the concrete mortar is compacted by centrifugal force, the structure becomes dense. As compacted and dense, there is a shortage of concrete mortar.

Concrete mortar is gravity due to the sphere side, so the concrete mortar is gathered to the sphere side. As a result, the shortcomings appear on the side. There is a problem that the coating thickness is less than the end of the horseshoe side. This problem on the phrase side is called problem-1.

Concrete mortar is attached to the mold wall, but the concrete mortar is insufficient in the hollow part opposite the mold wall. This causes the coating thickness of the tensile muscles not to meet the specification, or even the tensile muscles are exposed.

Insufficient cover thickness should be followed by reinforcement with concrete mortar after completion of electric pole. In particular, where the tensile muscle is exposed, it is cumbersome to follow-up work to be completely covered.

In the concrete poles actually used, for example, the reduction in the thickness of the horseshoe is explained as follows.

Length of concrete pole (L) = 16m,

Diameter α of the sphere, 403 mm,

Word diameter β = 190 mm,

Concrete thickness of the sphere and sphere T = 55 mm,

Number of tensile muscles = 12-16,

Concrete mortar; Slump = 0, sand + aggregate (maximum size of coarse aggregate; 19 mm)

After fabricating the electric pole by applying centrifugal force under the above conditions, the concrete thickness T on the horseshoe side was reduced to 40 mm by 15 mm. The concrete thickness T = 55mm was taken into account at least the concrete coating thickness of the horse's tensile muscles, 40mm is not enough as the coating thickness of the tensile muscles.

Looking at the relationship between the lack of concrete mortar caused by the centrifugal force in relation to the prior art as follows.

First, the prior art-1 of FIGS. 1 and 2 relates to a manufacturing method and a manufacturing apparatus of the pole of Patent No. 10-0376818.

A tension root 64 is disposed in the mold 20, and one end of the tension root 64 is provided by the tension nut 300 on the spherical tension root fixing plate 34 and the other end of the tension root fixing plate 44. It is fixed

In particular, the tension root 64 inserted into the horse plate 40 is inserted and fixed to the bolt hole 440 of the horse plate 40 as shown in FIG.

The tension of the tensile muscles 64 is a method of applying tension to the tension muscles 64 by moving the horseshoe plate 40 a certain distance while one end of the tension muscles 64 is fixed to the spherical tension muscle fixation plate 34. .

Means for moving the horse plate 40 is a connection ring 200 and the tension shaft 50 as shown in FIG. The connection ring 200 is also connected to the horse plate 40 at the same time. That is, the connection ring 200 has a structure in which the tension root 64 penetrates the bolt hole 440 and is simultaneously connected with the horse plate 40 fixed by the tension nut 300. Although not shown, the tension axis 50 is an axis connected with the hydraulic pressure.

In other words, the connection ring 200 is positioned between the horse plate 40 and the tensile shaft 50 to transfer the tensile force of the tensile shaft 50 to the connection ring 200, and the tensile force transmitted again is the horse plate 40 By transferring to the horse plate 40 by moving a predetermined distance to give a tensile force to the tension root (64).

However, despite the lack of concrete mortar on the horseshoe by centrifugal force, there is no space to fill the lack of concrete mortars on the horseshoe.

This is because, as in FIG. 2, the horse plate 40 is completely blocked except for the bolt hole 440.

As the structure of the prior art-1, the concrete mortar deficiency on the horseshoe side cannot be filled by centrifugal force.

Reference numerals related to the prior art-1 of FIG. 1, 14 is a word, 20 is a mold, 23 is a circle, 30 is a circle plate, 32 is a sphere tension plate, 46 is a copper plate, 52 is a nut, 220 is a hook groove, 420,422 Is a hanger

Next, the prior art-2 relates to a manufacturing apparatus and a manufacturing method of the pole of Patent No. 10-0766425. 3 and 4 are shown.

The prior art-2 differs only from the improvement of the configuration of the horseshoe plate 40 to which the tension root 64 is fixed while using the prior art-1 as it is, as follows.

The horse plate 40 of the prior art-2 has a circular space 400 is formed in the center, the size of the circular space 400 is almost similar to the size of the inner space of the electric pole (100). Tensile muscle guide fixing hole 440 is formed on the outer wall of the circular space 400. The length of the guide fixing hole 440 is determined by the design position of the tensile muscle 64. Since the width of the guide fixing hole 440 should be such that the tension root 64 can be inserted freely, it is generally slightly larger than the diameter of the tension muscle 64.

The horseshoe plate 40 and the horseshoe plate 40 are fixed to the horseshoe plate 40 and the horseshoe plate 40 is fixed to the horseshoe plate 40 is fixed to the horseshoe plate upper cover 74 is installed. Fixing of the horseshoe fixing plate bottom cover 72 and the horseshoe fixing plate top cover 74 is fixed by the horseshoe fixing plate fixing cover fastening nut 350 by inserting the cover fixing rod 48.

However, even in the prior art-2, there is no space for filling the shortage of concrete mortar on the horseshoe side.

On the horse plate 40 in contact with the concrete and the horse plate 40 to which the tension roots 64 are fixed, respectively, a bottom cover 72 and a horse stop plate top cover 74 are installed, and a cover fixing rod 48 is provided. (See Fig. 4) There is no space at all in the bottom cover 72 and the top cover 74 of the horse holding plate, and there is no structure to fill the shortage of concrete mortar. .

As the structure of the prior art-2, the concrete mortar deficiency on the horseshoe side cannot be filled by centrifugal force.

Reference numerals in FIGS. 3 and 4 are the same as in the prior art-1 and will be omitted. 2A is a support flange of the spherical mold, and B is a support flange of the spherical mold.

Now, problem 2 on the sphere side will be described.

First, the prior art-2 will be described.

The circular structure of Fig. 3 is composed of a flange plate (A) of a circle mold and a single circle plate (30), while the flange (A) of the mold and the circle plate (30) are assembled and fixed by fastening bolts.

One end of the tension root 64 is fixed to the spherical plate 30. The other end of the tension root 64 is fixed to the horse plate 40.

3 does not show a fastening bolt for assembling and fixing the mold flange A and the one-piece disk 30. As shown in FIG. Usually, the mold flange A and the spherical plate 30 are assembled and fixed by fastening bolts. This is to facilitate the dismantling of the original plate 30 in the mold flange (A) when demolding.

Since the spherical plate 30 of FIG. 3 is subjected to centrifugal force while fixing the tensioning muscle 64 to which tension is applied, the weight of the spherical plate 30 is usually 40 kg or more.

Lifting or disassembling and re-mounting the disc 30 or more than 30kg in order to assemble to the mold flange (A) is generally a work-dependent work, so the workability is significantly reduced due to its weight There is this. This is problem-2 on the sphere side.

Since dozens of molds are usually operated at a time, the larger the number of molds, the lower the workability due to the weight of the disk 30.

In addition, the tension root 64 fixed to the disk plate 30 should be in line with the insertion groove of the disk plate 30. This is because when the tension root 64 has a very small inclination angle that is not in line with the insertion groove, a loss of tensile force occurs due to the frictional force caused by the tension force applied to the tension root 64.

It is also not easy to insert the tension root 64 into the insertion groove of the spherical plate 30 while the spherical plate 30 is assembled and fixed with the mold flange A. FIG.

Next, the prior art-1 will be described.

Fig. 1 is also assembled and fixed to the spherical plate 30 by fastening bolts to the mold flange A as shown in Fig. 2 while having the original spherical plate 30 as shown in Fig. 2. The difference from FIG. 2 differs only in that the sphere tension plate 32 is separately added to the sphere plate 30.

Since the weight of the disc 30 is 40 kg or more, as in the salping bar in FIG. 2, the problem of FIG. 2 is the same as that of FIG. 1.

However, FIG. 2 is a problem because the spherical tension plate 32 is added separately, which is more heavy and the insertion of the tensile muscle 64 becomes more difficult.

On the other hand, in the pole production apparatus, the technical force is concentrated in arranging and fixing the tension muscles on the horse plate.

This is because the horseshoe is smaller in diameter than the raw balls. The length of the pole is proportional to the number of tensile muscles.

It is not possible to place a large number of tensile muscles in small diameter spheres. The number of tensile muscles is determined by the diameter of the spokes.

It is advantageous to impart tensile force to the tension muscles in the words. The inclination of 1/75 is the side on which the inclined side is inclined, and the incidence side is inclined. It is easy on the horse's side to apply tension to the tension muscles and make the slope easier. For this reason, the tension is usually done on the horseshoe side and the fixing is usually done on the spherical side.

(a) The present invention predicts the deficiency of the concrete mortar on the horseshoe side caused by the compaction by centrifugal force in the manufacturing process of the concrete pole in advance, first by applying a preliminary centrifugal force to the molds to reach the horseshoe shortage state and then It stops and fills the lack of concrete mortar on the horse's side, and puts regular centrifugal force on the mold to make the finished horse's coating thickness become the design thickness. It is easy to handle assembling and disassembling work by dividing the weight into the support plate, and the assembly and disassembly structure is also formed to facilitate assembly and disassembly while sufficiently supporting the tensile force of the tensile muscle. Easily install and demold molds by easy installation of tensile muscles and assembly and disassembly of molds Its purpose is to make it an enemy

(b) The lack of concrete mortar on the horse's side is added to make the covering's thickness on the horse's side the design thickness, thus eliminating the need for subsequent steps to reinforce the coating's thickness after the pole is completed, and at the same time making the pole's production more efficient and economical. At the same time, the shape of the pressing surface of the spherical support plate and the pressing part of the spherical tension plate supported thereon is formed into a closed circular shape, so that even if a strong tensile force by the tension muscle is applied to the pressing portion of the spherical tension plate, Another purpose is to stably be supported by the assembly structure of the pressing ground,

(c) Using tension hinge bolts inserted into the insertion grooves of the spherical and the spherical side to fix both ends of the tension muscles, the tension hinge bolts should be aligned with the direction of the tension muscles. Another goal is to minimize losses,

(d) In addition, through the mortar inlet and the round hole, the mortar inlet is formed on the horse's side and the circular hole on the side of the sphere. Another goal is to reduce the energy required for curing by shortening.

The present invention is to solve the problem--1 of the sphere side of the one-weight body while at the same time to solve the problem--1 on the horseshoe side of the coating thickness is insufficient due to the lack of concrete mortar on the horseshoe by centrifugal force. The slope of the pole is 1/75, so the lack of concrete mortar is always the smaller diameter. In general terms, the smaller diameter is a sphere, and the larger diameter is a sphere. In other words, with the Jeonju standing on the ground, the ground is the sphere and the other side is the other side.

In the present invention, the terms "circle" and "spherical" are used as they are, "the word is smaller in diameter, the diameter is greater in diameter."

In this definition, not only "sphere = fixed side, horse = tension side" is established.

The opposite is also true. That is, "a sphere = a tension side, a horse sphere = a fixed side" is established.

The present invention seeks to solve the problem-1 and the problem-2 firstly in terms of "sphere = fixed side, end sphere = tension side", and secondly, "sphere = tension side, sphere = fixed side".

1) The configuration of the present invention in the first aspect of "circle = fixed side, horse = tension side" is as follows.

In the production apparatus for fixing the side of the horseshoe side, the tension root 64 is tensioned by the tension on the horseshoe side, the concrete mortar into the mold and then centrifugal force applied to the mold to produce a concrete pole

In addition, the direction of the tension bolt insertion groove 512 of the horseshoe plate 510 and the tension bolt insertion groove 954 of the spherical tension plate 900B coincides with the inclination direction of the tension root 64.

The locking portion 820 having the exhaust hole 830 and the rubber cap 800 having the insertion portion 810 are inserted into the mortar insertion space portion 514 formed by the horse plate 510.

Will be. This is because the rubber cap 800 inserted into the mortar insertion space portion 514 is removed during curing. In the case of steam curing, the steam is contacted evenly through the hollow hole, so that the curing quality of concrete pole is not only excellent, and the curing time of 8 hours can be shortened by 1 hour or more, thereby greatly reducing energy.

2) The configuration of the present invention in the second aspect of "circle = tension side, horse = fixed side" is as follows.

hinge grooves

In the small hollow portion 950 of the spherical tensile plate 900B, a rubber cap 800 having a catching portion 820 having an exhaust hole 830 and an inserting portion 810 is inserted.

In addition, the central circular hole 515a of the blocking plate 515 blocking the mortar insertion space portion 514 of the horseshoe tension plate structure (P) formed integrally with the horseshoe plate, and the spherical tension plate and the support plate are divided on the horseshoe side. The small hollow portions 950 of the spherical tensile plate 900B of the prefabricated spherical structure Q pass through each other. This is because the rubber cap 800 inserted into the mortar insertion space portion 514 is removed during curing. Not only the curing quality of concrete pole is excellent, but the curing time of 8 hours can be shortened by 1 hour or more, and the energy is greatly reduced.

The present invention predicts the deficiency of the concrete mortar on the horseshoe side caused by the compaction by the centrifugal force in the manufacturing process of the concrete pole in advance, and first, by applying a preliminary centrifugal force to the molds to reach the horseshoe shortage state and then stop the molds. Since the side is filled with insufficient concrete mortar, there is an effect that the cover thickness of the horseshoe side becomes the design thickness.

Since the lack of concrete mortar on the horse's side is added to the design thickness on the horse's side, there is no need for subsequent work to reinforce the thickness after the pole is completed, making the pole pole efficient and economical.

It is a structure that can be added to the mortar of the shortage, and it is a structure in which the fixing and support of the tensile muscles to which tension is given is supported by a mold. .

Since the inclination of the pole is 1/75, and the inclination of the tension muscle is the same, the tension-bearing force of the tension muscle can be minimized by forming the tension-muscle insertion groove of the horse plate to match the inclination of the tension muscle. have.

Since the horseshoe plate and the horseshoe plate are integrally formed, the structure is simple, but it is easy to impart a tensile force to the tensile muscle, and at the same time, the mortar deficiency on the horseshoe side can be easily introduced.

In addition, since the present invention is divided into two circular tension plate and circular support plate, unlike the conventional circular plate, it is easy to handle the assembly and disassembly work by the divided weight, and the assembly and disassembly structure is also tensioned. It is easy to assemble and dismantle while sufficiently supporting the tensile force of the muscle, and it is easy to install the tensile muscle on the spherical tension plate and to assemble and disassemble the mold, so that the mold can be efficiently installed and demolded.

Since the shape of the pressing surface of the circular support plate and the pressing part of the circular tension plate supported thereon is closed, the assembly structure of the pressing portion and the pressing surface is subjected to strong tensile force by the tension root applied to the pressing part of the circular tension plate. There is an effect that the support is sufficient and stable.

Since the small hollow part of the spherical tension plate is blocked by the blocking plate, the concrete mortar inside the mold due to the centrifugal force is prevented from popping out of the mold.

Not only did the tension bolt insertion groove of the spherical tension plate match the inclination of the tension muscle, but the micro error was adjusted by the hinge portion of the tension hinge bolt and the corresponding hinge groove, so that the tensile strength loss of the tension muscle due to frictional force was reduced. There is an effect that is minimized.

In addition, since the mortar inlet is formed on the horse's side and the circular hole is formed on the spherical side, steam is uniformly contacted inside the hollow through the mortar inlet and the circular hole during steam curing, resulting in excellent curing quality and curing time over 1 hour. It is a useful invention with the effect that the energy required for curing is shortened significantly.

Referring to the concrete pole production apparatus improved with the sphere and the sphere of the present invention in detail as follows.

The terms "sphere" and "spherical" shall be used as it is in the present invention, "the word shall have a smaller diameter, and the sphere shall have a larger diameter".

At all times, only on “smaller diameters” centrifugal forces cause shortages of concrete mortar.

1) The first aspect of “circle = fixed side, end = tension side” is explained as follows.

In this case, the "smaller diameter" is the spoken side. The horseshoe side is the tension side, and the corresponding spherical side is the fixed side.

Accordingly, the horseshoe side is provided with a horseshoe tension plate structure (P) formed integrally with the horseshoe plate, and the corresponding horseshoe is provided with a prefabricated wheel structure (Q) in which the spherical tension plate and the support plate are divided.

A) First, a description will be given of the "horse plate tension plate structure (P) formed integrally with the horse plate", which is the tension side installed on the horseshoe side.

The basic concept of applying a tensile force to the tension muscles arranged over the spherical side and the spherical side and producing the concrete pole by centrifugal force is the same as in the present invention or the prior arts 1 and -2.

However, only on the horseshoe side of the "horseshoe tension plate structure (P) formed integrally with the horseshoe plate" on the sphere side, only the "prefabricated sphere structure (Q) in which the spherical tension plate and the support plate is divided" is installed.

More specifically, the "rolling plate tension plate structure (P) formed integrally with the horseshoe plates" of the present invention is to make the horseshoe-side structure capable of adding the concrete mortar of the shortage because the shortage of concrete mortar occurs on the horseshoe side. In addition, the structure is simple and easy to fix and support the tensile muscle to which tension is applied.

As in the configuration described in the above problem solving means, by forming integrally the horse plate 510 to form the mortar insertion space portion 514 and the horse body plate 520 to form the mortar insertion space portion 540 integrally Tensile force is applied to the tension muscle 64 by the tension of the horseshoe plate 520, and thus the tension muscle 64 is stretched, and the length of the extension muscles is adjusted to the adjustment spiral 522 of the horseshoe plate 520. It will appear inserted. Tensile force is introduced into the tension root 64 only when the stretched length is fixed as it is.

In order to keep the tension muscles 64 stretched as it is, the horseshoe tension fixing nut 600 and the horseshoe side support flange (B) inserted into the adjusting spiral 522. Since the horseshoe-side support flange B is fixed to the mold 20, it is the horseshoe plate 520 and the horseshoe fixing nut 600 which are moved.

In order to introduce a tensile force to the tension root 64, the distance to the horseshoe plate 520 has to be moved to a stationary state. When the horseshoe fixing nut 600 is rotated so as to be in contact with the horseshoe-side support flange B, the horseshoe-fixing nut 600 is fixed and supported by the horseshoe-side support flange B, and the horseshoe tension plate 520 is not moved. It is fixed to the position as it is.

In addition, the structure of the horse plate 510 and the horse tension plate 520 is integrated into the mortar insertion space portion 514 consisting of the horse plate 510 and the mortar insertion space portion 540 in the horse tension plate 520. Since the structures are in communication with each other, it is easy to input the mortar deficiency amount of the horseshoe into the mold.

As such, the structure in which the horse plate 510 and the horse tension plate 520 are integrally formed has a simple structure, and it is easy to apply a tensile force to the tensile muscle 64, and at the same time, it is easy to input a mortar deficiency amount on the horse side. Structure.

In addition, although the tension bolt 700A may be used, the inclination of the pole is usually 1/75, so it is advantageous to use the tension hinge bolt 700.

The tension bolt 700A may use what is described in Korean Patent No. 10-0970674. (See Fig. 8)

If the reference numeral in Fig. 8 is used as it is, the configuration of the tension bolt 700A is as follows.

The tensioning bolt 700A is composed of an insertion and fastening portion 740A having a head portion 720A, an insertion portion 730A, and a spiral portion 750A, and the spiral portion 920 of the tension root 900 is tensioned. It is a structure inserted into the spiral part 750A of the bolt 700A. The length S of the spiral portion 750A of the tension bolt 700A is equal to the length of the spiral portion 920 of the tensile muscle 900.

Tension hinge bolt 700 is shown in FIG.

The tension hinge bolt 700 is the same as the tension bolt 700A, except that the head portion 710 has a hinge portion 720 and the insertion portion 730 having an inclined surface is different. The spiral portion is formed inside the insertion portion 730. The spiral portion of the insertion portion 730 and the spiral portion 64a of the tensile muscle 64 are coupled to each other.

The hinge portion 720 of the tension hinge bolt 700 corresponds to the hinge groove 516 formed in the tension bolt insertion groove 512 of the horseshoe plate 510. (See Fig. 5).

The hinge portion 720 of the tension hinge bolt 700 and the hinge groove 516 corresponding thereto will be described in detail as follows.

Since the pole and the horse are different in diameter, the inclination of the pole is inclined to 1/75 with respect to the axis of rotation. Tensile muscles (64) in the reinforcement is also inclined state in order to match the direction of the inclined tensile muscles (64) of the hinge portion 720 of the tension hinge bolt 700 and the corresponding plate 510 A hinge groove 516 is formed in the tension bolt insertion groove 512. When the direction of the tension bolt insertion groove 512 of the horse plate 510 coincides with the inclination direction of the tension muscle 64, there is no loss of tensile force added to the tension muscle 64.

In other words, when the direction of the tension hinge bolt 700 inserted into the tension bolt insertion groove 512 of the horse plate 510 coincides with the inclination direction of the tension muscle 64, the tensile force added to the tension muscle 64 is frictional force. The loss does not occur.

Therefore, it is preferable to form the tension bolt insertion groove 512 of the horseboard 510 to match the inclination of the tension root (64). It is structurally advantageous because the tensile force loss of the tensile muscle 64 due to the frictional force is minimized.

However, even if the tension bolt insertion groove 512 of the horse plate 510 matches the inclination of the tension root 64, there will always be an error.

Measures for overcoming this error are the hinge portion 720 and the hinge groove 516. By adjusting the hinge portion 720 and the hinge groove 516, the tension hinge bolt 700 is matched with the inclination of the tensile muscle 64. The diameter of the tension bolt insertion groove 512 of the horse plate 510 is 1 ~ 2mm larger than the diameter of the tension hinge bolt 700. Because of this margin, fine adjustment by the hinge portion 720 and the hinge groove 516 is accommodated.

On the other hand, the locking portion 820 having the exhaust hole 830 and the rubber cap 800 formed with the insertion portion 810 is inserted into the mortar insertion space portion 514 formed of the horseboard 510.

The mortar inserting space portion 514 is a space for injecting the mortar shortage on the horseshoe side.

When the mold is rotated by the centrifugal force, by blocking the mortar insertion space portion 514 with a rubber cap 800 to prevent the concrete mortar from jumping out of the mold.

The exhaust hole 830 of the rubber cap 800 is for discharging gas such as water vapor generated by heat of hydration in the mold out of the mold.

The tensioning of the tension roots 64 is accomplished by a tensioning device (not shown). The tension device may be fixed to the tension device fastening unit 530 and the tension device may be tensioned. At this time, the tension device is also provided with an insertion portion and a protrusion corresponding to the protrusion 532 and the insertion portion 534 of the tension device fastening portion 530.

B) Next, a description will be given of the "prefabricated circular structure (Q) divided by the spherical tension plate and the sphere support plate" which is a fixed side installed on the sphere side as follows.

Conventionally, since the structure is divided into a one-piece body weight plate is divided into a sphere support plate (900A) having a mass study 910 and a sphere tension plate (900B) having a small hollow portion 950, the weight is shared, easy to handle and disassemble Not only the work is easy but also the insertion of the tension root 64 is easy to manufacture the work of the pole.

The assembly structure divided into the sphere support plate (900A) and the sphere tension plate (900B) will be described in more detail as follows.

Since the mortar contact surface 916 of the spherical support plate 900A is in close contact and contact with the spherical side support flange A, fixing between the spherical support plate 900A and the support flange A is firm and stable.

In addition, since the edge fixing support jaw 914 is supported on the interface of the mold 20, the support flange A of the mold 20 and the spherical support plate 900A are stable.

The pressing surface 930 of the spherical support plate 900A has a closed circular shape as shown in FIG. In addition, the pressing portion 960 of the spherical tension plate 900B that is supported on it is also a closed circular shape.

As described above, since the shape of the pressing surface 930 of the circular support plate 900A and the pressing portion 960 of the circular tensile plate 900B supported thereon are closed, the pressing portion of the circular tensile plate 900B ( The strong tensile force by the tension root 64 applied to the 960 is sufficiently and stably supported by the assembly structure of the pressing portion 960 and the pressing surface 930.

Since the tension bolt 700A and the tension hinge bolt 700 have been described in detail in the above a), they will be replaced by the a) and will be omitted here.

On the other hand, when the small hollow portion 950 of the spherical tension plate 900B is blocked by the blocking plate 970, the concrete mortar inside the mold 20 due to the centrifugal force is prevented from popping out of the mold 20.

Since the blocking plate 970 prevents the release of the concrete mortar, the thickness thereof may be thin.

The fixing of the blocking plate 970 is preferably fixed to the welding 972 to meet the inner vertical portion 966 while forming a straight line with the mortar contact portion 964. It is advantageous to drill a small circular hole 970a in the center of the blocking plate 970. It is for exhausting through the circular hole 970a. 80-100 mm is sufficient as the diameter of the circular hole 970a normally.

2) The second aspect of “circle = tension side, horse = fixed side” is explained as follows.

The "smaller diameter" is always the verb side. In this case, the horseshoe side is the fixed side, and the corresponding spherical side is the tension side.

Accordingly, a "spherical tension plate structure (P) in which a horse plate is integrally formed" is installed on the spherical side, and a "prefabricated sphere structure (Q) in which a spherical tension plate and a spherical support plate is divided" is installed on the corresponding spherical side.

A) First, the fixed side installed on the horseshoe side will be described as "prefabricated structure (Q) divided by the spherical plate and the support plate circle" as follows.

The rubber cap 800 is inserted into the small hollow portion 950 of the spherical spherical plate 900B in the “prefabricated spherical structure Q” in which the spherical spherical plate and the spherical support plate are divided.

At this time, the configuration of the rubber cap 800 is inserted into the locking portion 820 having an exhaust hole 830 is inserted into the mortar insertion small space portion 514 in the "terminal tension plate structure (P) formed integrally with the end plate" of the first term. It is the same as the configuration of the rubber cap 800 in which the portion 810 is formed.

Except for the configuration in which the rubber cap 800 is inserted into the small hollow portion 950 of the circular tension plate 900B in the “prefabricated circular structure (Q) divided by the circular tension plate and the circular support plate” installed on the horse sphere, It is the same as the "Prefabricated structure of circle (Q) with dividing circle tension plate and circle support plate" in the first paragraph above.

Therefore, the description of the prefabricated garden structure (Q) in which the spherical tension plate and the disc support plate are divided on the side of the sphere is described in the first paragraph “Prefabricated garden structure (Q) in which the spherical tension plate and the disc support plate is partitioned. Instead, it will be omitted here.

B) Next, the "tensive plate tension plate structure (P) formed integrally with the horse plate", which is the tension side provided on the spherical side, is as follows.

The structure and function of the "tensile plate structure formed integrally with the horse plate (P)" and the "tensile plate structure formed integrally with the horse plate (P)" installed at the end side of the first term above Is the same.

However, there is no rubber cap 800 inserted into the mortar inserting space portion 514 in the “rolling plate tension plate structure (P) in which a horse plate is integrally formed” which is installed on the spherical side. Instead, the mortar inserting space portion 514 is blocked. The only difference is that the blocking plate 515 is formed. In the center of the blocking plate 515, a circular hole 515a of about 80 to 100 mm is formed for exhausting.

Therefore, the description of the "horse plate tension plate structure (P) formed integrally with the horse plate is installed on the spherical side is replaced with the description of the" horse plate tension plate structure (P) formed integrally with the horse plate "of the first term installed on the sphere side, and here It will be omitted.
