Abstract

According to the present invention, the length of a tensile core is set to be equal to the distance between a proximal plate and a distal plate in order to prevent a surplus protruding length of the tensile core so that cutting is not necessary and stress does not remain in the tensile core disposed in a concrete electric pole as cutting by arc welding is not necessary, and since short coupling devices are inserted through insertion bolt holes of the proximal and distal plates, an assembling operation may be efficiently carried out due to easy handling and coupling. According to the configuration of the present invention: both end parts of a tensile core (900) are brought into contact with an inner surface (840A) of a distal plate (800A) and an inner surface (830B) of a proximal plate (800B); tension insert bolts (700A) are inserted through an insertion hole (820B) of the proximal plate (800B) and an insertion hole (820A) of the distal plate (800A) such that threaded portions (920) of the tensile core (900) can be screw-coupled to threaded portions (750A) of the tension insert bolts (700A) when the threaded portions (920) of the tensile core (900) are inserted into the threaded portions (750A) of the tension insert bolts (700A), wherein each of the tension insert bolts (700A) comprises a head portion (720A), an insertion portion (730A), an insertion-coupling portion (740A), and said threaded portion (750A); and inner surfaces (752A) of the threaded portions (750A) of the tension insert bolts (700A) are aligned with the inner surfaces (830B)(840A) of the proximal plate (800b) and the distal plate (800A). According to the present invention, the length of the tensile core is set to be equal to or slightly shorter than the distance between the proximal plate and the distal plate in order to prevent a surplus protruding length of the tensile core so that operations can be efficiently carried out and stress does not remain in the tensile core disposed in a concrete electric pole as cutting by arc welding is not necessary. In addition, since all of the tensile cores have the same length, the tensile cores may receive equal tension without eccentric force, and thus electric poles having stable structures can be produced.

Description

Fastening device for fastening the tension muscles on the horse's end and the sphere side and manufacturing method of the pole using the same

The present invention relates to a fastening device for fastening the tension muscles on the horseshoe side and the sphere side of the pole, and a method of manufacturing the poles using the same. Through the short fastening device, it is easy to handle and the work is efficient.

In addition, since the length of the tensile muscle is formed to be the same as the distance between the spherical plate and the horse plate, the structure is made so that the excess protrusion length of the tensile muscle does not occur, it is an efficient technique that omitted the cutting work.

In addition, since the length of the tensile muscles is the same length, it is a technology that produces structurally stable poles because the tensile force applied to each tensile muscle is the same, so that no eccentricity is generated.

In this way, the production of pole pole is efficient and the tensile force is uniform, so the structure of pole pole is stable and the protruding length of tensile muscle is not generated.

Centrifugal force manufacturing apparatus is divided into two divided molds (or dies), tension rods installed in the mold, disc and horse plates for firmly fixing the tension muscles at both ends, and tension means for applying tension to the tension muscles. And, and is composed of a connection ring for connecting the horse plate and the tension means.

The electroforming apparatus thus constructed is conventional. The circle is said to be the end of the pole, which is embedded in the ground, and the end of the pole on the opposite side.

Since the present invention is also an improvement on the basis of the conventional electric pole manufacturing apparatus, the basic manufacturing process of making the pole is the same.

The basic manufacturing process of Jeonju is explained by the conventional Jeonju manufacturing apparatus as follows.

(a) The two divided lower molds form a horizontal plane in the longitudinal direction and are firmly fixed, and the upper mold is not yet joined to the lower mold, and the tension rods are placed on the disc and the horse plate while the lower mold is opened. Insert

More than 12 tensile muscle through holes are formed in the disc and the horse plate. To place more than 12 tensile muscles.

The length of the pole produced is about 15m ~ 25m and is equal to the distance between the disc and the horse plate.

(b) Insert and fix the tension muscles in the through-holes of the disc and the horse plate.

It is a way to pull the horse plate by the tension means in the state that the original plate is fixed.

At this time, since the connection ring is connected to the horse plate and is also connected to the tensioning means, when the connection ring is pulled by the tensioning means, the tensile force is applied to the tensile muscle.

(c) Put the concrete mortar into the lower mold with the tensile force applied to the tension root, close the lower mold with the upper mold and apply centrifugal force to the mold.

(d) Apply the centrifugal force to cure the pole and then to cure the mold.

(e) Take the pole out of the mold. At this time, since the tension plate is connected to the disc and the end plate, it should be disassembled. Disassembly of the tensile muscles and the disc is released by cutting (cutting by welding), and disassembly of the tensile muscles and the spherical plate releases the horse plate from the tensile muscles by releasing the nut.

With respect to the basic fabrication process will be described in more detail with reference to Patent Registration No. 10-0376818 (see Fig. 1) with respect to the problems of the prior art.

Electric pole manufacturing apparatus 100 using the centrifugal force was made of a formwork 20 of two divided structures.

One side sphere 12 of the die 20 is formed with a spherical plate 30 and a spherical sphincter fixing plate 34, the tensile muscle 64 is penetrated through the spherical plate 30 and spherical sphincter fixing plate 34 The head 66 of the tension muscle 64 is inserted into and fixed to the spherical tensile muscle fixation plate 34.

The other end 14 of the formwork 20 has a horse plate 40 is formed, and the tension root 64 is penetrated through the horse plate 40, the long tension nut 320 and the end tension nut on the horse plate 40 340 is fixed.

As shown in FIG. 2, the tension root 64 is formed of a head 66 and a nut 680 on both sides.

The spherical tension root fixing plate 34 is provided with a fastening hole 36 through which the head 66 of the tension muscle 64 is inserted (see FIG. 3), and the nut of the tension muscle 64 is formed on the horse plate 40. A bolt hole 440 is formed in which the portion 680 enters and is fastened to the tension nuts 300.

The head 66 of the tension root 64 is inserted into the fastening hole 36 of the spherical tensile muscle fixing plate 34 and fixed in a locked state, and the nut part 680 of the tension muscle 64 is a horseshoe plate 40. Penetration through the bolt hole 440 of the) is fixed by the long tension nut 320 and the short tension nut 340.

Tensile muscle tension means for imparting tensile force to the tension muscles 64 is provided in line with the horseshoe plate 40. The tension root tensioning means is formed of a horse tension plate 42, the tension axis 50, the copper plate 46 and the nut 52.

The horse plate 40 and the horse tension plate 42 are connected by a connection ring 200.

The hanger jaw 420 of the horseshoe plate 40 and the hanger jaw 422 of the horseshoe tension plate 42 are coupled and connected to the hanger groove 220 of the connection ring 200.

Tensile force is applied to the tension root 64 by pecking the nut 52.

That is, when the nut 52 is split by the tensioner, a tensile force is induced on the tension shaft 50, and the tensile force is transmitted to the horse plate 40 through the connection ring 200. This imparts a tensile force to the tensile muscles 64 fixed to the horse plate 40.

As shown in FIG. 4, the spiral wire 62 is spirally welded to the main surface of the tension root 64 to form the frame 60. To reinforce the shear force.

Now, when the tensile force is applied to the tension root 64, the concrete mortar is put into the lower mold and then closed by the lower mold. The mold is rotated to form a pole having a hollow part by centrifugal force.

After curing the concrete pole 10 formed in the mold, the one connected to and fixed with the tension roots 64 in the sphere and the sphere is released to demould the mold.

That is, the tension root 64 is cut between the spherical plate 30 and the spherical tension plate 32 using a welding rod, and the connection ring 200 is separated and released from the spherical plate 40 at the same time.

After the mold is demolded, only the concrete pole remains, but still not the finished pole. This is because the tensile roots 64 protrude from both the sphere side and the horse sphere side of the pole.

The protruding tension root 64 should be cut to match the end face of the pole.

Now look at the problem caused by the protrusion of the tensile muscles 64 as follows.

First, the reason why the tensile muscles 64 protrude on the both ends of the pole and the horseshoe side will be described.

The protruding portion on the spherical side is a protruding portion formed by cutting between the spherical plate 30 and the spherical tension plate 32.

The reason for cutting between the spherical plate 30 and the spherical tension plate 32 is to quickly take out the pole from the mold and increase the number of times the mold moves.

You can't install too many molds. The size of one mold is too big.

Once cutting between the spherical plate 30 and the spherical tension plate 32 and then cutting the protrusion of the tension root 64 in the stockyard, electroforming is more efficient than cutting the protrusion of the tensile muscle 64 in the mold. to be. Actual pole production is doing this.

As shown in Fig. 5, the protruding portion d of the tension ball 64 on the horseshoe side is fixed length fixed by the insertion length d1 of the horseshoe plate 40 and the long tension nut 320 and the short tension nut 340. (d2) The sum of lengths.

In order to remove the pole from the mold, the long tension nut 320 and the short tension nut 340 must be loosened and the horse plate 40 must be disassembled. The protrusion d of the tension root 64 is formed by the insertion length d1 of the disassembled horse plate 40, the long tension nut 320, and the fixed length d2 of the short tension nut 340.

Next, look at the problems caused by the cutting of the tension root 64 projections.

The cutting means of the protruding tensile muscle 64 includes (1) cutting by oxygen welding or arc welding, and (2) cutting by saw blades.

Cutting between the spherical plate 30 and the spherical tension plate 32 of the Patent No. 10-0376818 is the cutting by welding.

Cutting by oxygen welding or arc welding causes high heat due to welding to be transferred to the tensile muscles embedded in the concrete, which generates adverse residual stress. As a result, the design strength is lowered by the residual stress of the tensile strength of the tensile root 64. In order to compensate for this, there is a problem in that it is more economical to use the tensile muscle 64 more.

In particular, when cutting by arc welding to facilitate cutting, high heat of about 4000 ° C. in a carbon arc and 3000 ° C. in a metal arc is generated.

When arc welding is performed while the spiral spiral wire 62 is integrally welded to the main surface of the tension bar 64, sparks are generated at the contact point between the tensile wire 64 embedded in the concrete and the spiral spiral wire 62. While high heat of 4000 ℃ is generated. This is because it is grounded at the contact point.

The high temperature of 4000 ℃ not only lowers the tensile strength of the tensile muscle 64, but also has a problem of destroying the concrete around it.

In the case of cutting the protruding portion of the tension root 64 by the saw blade, the saw blade must be in contact with the concrete end face, which is dangerous and the cutting operation is also difficult in practice.

In addition, the protruding portion of the tension muscle 64 on the horseshoe side is the length d, which is the sum of the insertion length d1 of the horseshoe plate 40 and the fixed length d2 of the long tension nut 320 and the short tension nut 340. This is the length to be cut and thus the excess length d of the tension root 64. The surplus length of the tensile muscle 64 is uneconomical.

Now look at the problem of Patent No. 10-0376818 (see Fig. 1) associated with the excess length (d) of the tensile muscle (64).

(a) The length L of the tension root 64 is the length L1 between the disc and the end plate plus the surplus length d. The length L of the tension root 64 is longer than the distance L1 between the spherical plate and the horse plate.

(b) As shown in Fig. 6, the tension root 64 has a shape in which the head 66 is formed on the spherical side and the nut portion 680 is formed on the spherical side.

(c) The order of fixing the tensile muscle 64 between the disc and the horse plate first passes through the nut portion 680 of the tension muscle 64 through the fastening hole 36 of the disc, and then again After passing through the bolt hole 440, the nut part 680 of the tension root 64 is screwed and fixed with the long tension nut 320 and the short tension nut 340. FIG.

(d) As described above, the nut part 680 of the tension root 64 is first inserted into the fastening hole 36 of the spherical plate and then inserted into the bolt hole 440 of the spherical plate. As long as (L) is not only 15 ~ 25m but also inserted into small holes, it is extremely difficult to handle long tensile muscle 64 and at the same time, it is difficult to insert into small holes. There is this inefficient problem.

As described above, Korean Patent No. 10-0376818 is a problem that is difficult to insert and fix the tensile muscles, and a problem derived from the excess length of the tensile muscles.

(a) Since the shape of the tension muscles is formed by the head 66 and the nut portion 680, the order of installation on the spherical plate and the spherical plate is determined. In other words, the nut part 680 of the tensile muscle first penetrates the fastening hole 36 of the spherical tensile muscle fixing plate 34 and then passes through the bolt hole 440 of the horse plate 40. To penetrate the two small fastening hole 36 and the bolt hole 440 by controlling the tensile muscles over 20m is very difficult to handle the tensile muscles is not easy installation work takes too much installation time. This is the main reason that pole production becomes inefficient.

(b) Since the tensile muscle penetrating the horse plate is fixed by the long tension nut 320 and the short tension nut 340, the insertion length d1 and the long tension nut 320 and the short tension of the horse plate 40 are fixed. The excess length d is generated by adding the fixed length d2 of the nut 340.

① The excess length (d) of the tensile muscle shall be cut. Cutting is by arc welding or oxygen welding. It is a cause of introducing the residual stress which is disadvantageous in the tensile muscle by generating high heat in the tensile muscle embedded in the concrete by the spark of arc welding. Residual stress has a problem of lowering the tensile strength of the tensile muscles.

② The excess length (d) of the tensile muscle to be cut is not only a waste of the material, but also the cutting work has to be inefficient because the pole pole production is inefficient.

③ Since the length L of the tension root 64 is longer than the distance L1 between the spherical plate and the spherical plate by the surplus length d, the fastening hole 36 and the spherical plate of the sphincter sphincter fixing plate 34 Insertion to be inserted into the small hole of the bolt hole 440 of 40) and the installation of the tension muscles is extremely difficult problem.

In the present invention, the length of the tensile muscle is equal to the distance (L1) between the original plate and the horse plate so that the excess length (d) of the tensile muscle does not occur and at the same time there is no excess length (d), so that cutting is not necessary. Its purpose is to prevent residual stress from occurring in the tensile muscles embedded in concrete poles due to cutting by arc welding.

Insertion and bolt hole penetration of the spherical plate and the horseshoe plate is not made to penetrate the very long tensile muscles, but allows the fastening device of very short length to penetrate and facilitates the handling and fastening of the fastening device and the structure of the fastening device is simple. There is another purpose to make the fastening work by the fastening device more efficient,

Another purpose is to improve the productivity of pole poles by cutting the mold and eliminating the need for cutting by acquiring completed pole poles with mold release.

Polygonal wrench grooves are formed on the tension insert bolts and the tension bolt heads, so that one bolt can be fastened unlike the prior art fasteners divided into long and short bolts.

The present invention is a fastening device by the tension insert bolt 700A and the tension bolt 700B. The basic concept is the same whether the tension is tightened with the tension insert bolt 700A or the tension muscle with the tension bolt 700B.

First, the configuration of the fastening device by the tension insert bolt 700A is as follows.

Comprising a spherical plate 800B having an insertion hole 820B, and a horseshoe plate 800A having an insertion hole 820A formed therebetween, and a tension root is installed therebetween, and the spherical plate 40 is connected to the connection ring 200. In a conventional electroforming apparatus of the present invention, in which tension means are applied to the tension muscles by the tension muscle tension means while the tension muscle tension means is connected to each other.

Both ends of the tension root 900 are provided to be in contact with the inner surface 840A of the horse plate 800A, and the inner surface 830B of the wheel plate 800B, the tension insert bolt 700A is a spherical plate ( The spiral portion 920 of the tension root 900 is inserted into the spiral portion 750A of the tension insert bolt 700A by penetrating the insertion hole 820B of the 800B and the insertion hole 820A of the horse plate 800A. And the tension insert bolt 700A is formed of the head portion 720A, the insertion portion 730A, the insertion / fastening portion 740A and the spiral portion 750A, and the tension insert bolt 700A. The inner surface 752A of the spiral portion 750A is positioned to coincide with the spherical plate 800B and the

inner surface

830B and 840A of the spherical plate 800A. Constitution of fastening device for fastening muscles.

In addition, a polygonal wrench groove 722A is formed in the head portion 720A of the tension insert bolt 700A.

In addition, a circular stepped portion 830A in which the head 720A of the tension insert bolt 700A is supported is formed on the outer side of the insertion hole 820A of the horseboard 800A.

Next, the configuration of the fastening device by the tension bolt 700B is as follows.

One end of the tension coupler 750B is helixed and coupled to both ends of the tension root 900 to the stopper 752B, and the other end thereof is the inner surface 830B of the spherical plate 800B and the spherical plate 800A. 840A, the tension bolt 700B passes through the insertion hole 820B of the spherical plate 800B and the insertion hole 820A of the horse plate 800A, and then the other end of the tension coupler 750B. The screw 740B of the tension bolt 700B of the tension bolt 700B is inserted into the portion 754B, but the tension bolt 700B includes the head 720B, the insertion portion 730B, and the spiral bolt portion 740B. The spiral bolt portion 740B with the inner surface 742B of the spiral bolt portion 740B aligned with the

inner surface

830B and 840A of the spherical plate 800B and the horse plate 800A. ) Is a constitution of a fastening device for fastening the tension muscles on the horseshoe side and the sphere side of the pole, characterized by being spirally coupled to the stopper 752B of the tension coupler 750B.

In addition, a polygonal wrench groove 722B is formed in the head portion 720B of the tension bolt 700B.

In addition, a circular stepped portion 830A in which the head portion 720B of the tension bolt 700B is supported on the outer side of the insertion hole 820A of the horseboard 800A is formed.

A) Tightening device by tension insert bolt 700A

Both ends of the tensile muscles 900 are in contact with the inner surface 840A of the horse plate 800A, and the inner surface 830B of the spherical plate 800B. It is a structure that does not penetrate the insertion hole (820A) and the insertion hole (820B) of the disk plate (800B). Instead, the tension insert bolt 700A having an extremely short length penetrates the insertion hole 820A of the horse plate 800A and the insertion hole 820B of the spherical plate 800B. The tension insert is inserted into the wrench groove 722A of the tension insert bolt 700A while the spiral portion 920 of the tension root 900 is inserted into the spiral portion 750A of the penetrated tension insert bolt 700A. The bolt 700A may be rotated to screw and engage.

Thus, by forming the wrench groove 722A in the tension insert bolt 700A, not only the tension insert bolt 700A can be easily fastened but also the fastening with a single bolt is different from the conventional fastening divided into long and short bolts. Possible to fasten the work.

Rather than penetrating the long tensile muscle 900, which is 20m or more in length, it is easy to penetrate the tension insert bolt 700A that is very short in length, as well as a rotational work for fastening.

This is because the tension insert bolt 700A is easier to handle than the long tensile muscle 900.

The concrete mortar is poured in a state in which tensile force is applied to the tensile muscles 900. After concrete mortar is cured, it is demolded. Together with the demolding, the sphere plate 800A and the sphere plate 800B are separated.

Tensile force 900 is given a tensile force is fixed by the adhesion of the concrete, so the tensile force of the tensile muscles 900 acts as a compressive force of the concrete pole. In other words, imparting tensile force to the tensile muscle 900 is to increase the support strength of the pole by introducing a compressive force to the completed pole.

Electric poles are vulnerable to horizontal forces in an upright state because they are elongated in shape compared to the cross-sectional area. The introduction of compressive force into the pole is intended to reinforce it.

More than 12 tensile muscles 900 are inserted in the pole. The compressive forces introduced by this article should be balanced. Eccentricity due to power imbalance should not occur. Twelve copies shall be arranged symmetrically to each other. The tension should be given equally. Careful attention is required.

The spiral of the tension insert bolt 700A while the inner surface 752A of the spiral portion 750A of the tension insert bolt 700A coincides with the

inner surface

830B and 840A of the spherical plate 800B and the horse plate 800A. The length S of the portion 750A and the insertion length S of the spiral portion 920 of the tensile muscle 900 inserted thereto are the same. To this end, the spiral portion 920 of the tension root 900 is screwed and coupled to the end of the spiral portion 750A of the tension insert bolt 700A.

All 12 bones must have the same length to impart the same tensile force to the tensile muscles 900. It is to make structurally stable pole without eccentricity.

Meanwhile, since both ends of the tension root 64 are in contact with the

inner surfaces

830B and 840A of the spherical plate 800B and the spherical plate 800A, the tension is completed after the tension pole is completed with the release of the tension insert bolt 700A. Since there is no surplus length of the root 900 and there is no need to cut the surplus length, residual stress due to the cutting is not generated.

B) Fastening device by tension bolt 700B

The fastening device by the tension bolt 700B and the fastening device by the tension insert bolt 700A have the same basic concept except for the tension coupler 750B.

Both ends of the tension coupler 750B, to which the tension root 900 is coupled, in the state in which both ends of the tension root 900 are helically coupled to the stopper 752B of the tension coupler 750B. ) And the

inner surface

830B and 840A of the spoke plate 800A, and the inner surface 742B of the spiral bolt portion 740B of the tension bolt 700B is the original plate 800B and the spoke plate ( The spiral bolt portion 740B of the tension bolt 700B is spirally coupled to the stopper 752B of the tension coupler 750B while coinciding with the

inner surfaces

830B and 840A of the 800A. This is to make the length of the tensile muscles 900 the same.

This is because the same tensile force is applied to the 12 tensile muscles 900 so as to make a structurally stable pole without eccentricity.

In addition, by forming a wrench groove 722B in the tension bolt 700B, not only the tension bolt 700B can be easily fastened but also can be fastened with a single bolt unlike the conventional fastening divided into long and short bolts. The work is efficient.

Wrench grooves 756B are also formed on the outer circumferential surface of the tension coupler 750B to facilitate fastening by a wrench. The shape of the wrench groove 756B of the tension coupler 750B is also preferably polygonal.

Both ends of the tension coupler 750B coupled with the tension root 900 are in contact with the

inner surface

830B and 840A of the spherical plate 800B and the horse plate 800A, and thus the tension bolt 700B is released. Together with the completion of the pole, there is no surplus length of the tension root 900, and even if the tension bolt 700B is released, the tension coupler 750B remains in the concrete pole as it is embedded.

In particular, the present invention has one feature in the structure that does not generate excess protrusion length in the tensile muscle, and another feature in the structure in which a uniform tensile force is introduced into the tensile muscle.

The configuration related to the structure in which uniform tensile force is introduced into the tension roots is that, in the case of the tension bolt 700B, the inner surface 742B of the helix bolt portion 740B of the tension bolt 700B includes the spherical plate 800B and the spherical plate 800A. And a circular stepped portion in which the head portion 720B of the tension bolt 700B is supported at the outer portion of the insertion hole 820A of the horse plate 800A. 830A) and all of the same depth configuration. This is the configuration in which the spiral portion 920 of the tension root 900 must be completely screwed into the insertion portion 730A of the tension insert bolt 700A.

In the case of the tension bolt 700B, the tension coupler 750B to which the tension root 900 is coupled while the helix 920 of both ends of the tension root 900 is spirally coupled to the stopper 752B of the tension coupler 750B. The inner surface 742B of the spiral bolt portion 740B of the tension bolt 700B and the structure in which both ends thereof contact the inner surface 830B and the 840A of the spherical plate 800B and the horse plate 800A. The structure that matches the

inner surfaces

830B and 840A of the spherical plate 800B and the spherical plate 800A, and the spiral bolt portion 740B of the tension bolt 700B are the stopper 752B of the tension coupler 750B. That is the configuration that helixes and combines.

In the present invention, since the length of the tension muscle is equal to or slightly smaller than the distance between the original plate and the horse plate, the excess length (d) of the tension muscle is not generated. As a result, residual stress does not occur in the tensile muscles embedded in the concrete pole.

The long length of the tension bar is located between the disc and the end plate, and the short length fastener is inserted through the insertion hole of the disc and the end plate to be fastened to the tension bar. Not only is easy, but the structure of the fastening device is simple, there is an effect that the fastening operation is performed efficiently.

Since the fastening device is disassembled at the position coinciding with the inner surface of the spherical plate and the end plate, the excess protrusion of the tension muscle does not occur, so that the finished pole is released without the cutting device and the cutting is not necessary. to be.

Polygonal wrench grooves are formed on the tension insert bolt and the head of the tension bolt, so that unlike the conventional fastening divided into long and short bolts, it is possible to fasten a single bolt and thus the fastening work is efficient.

Since the length of the tension muscle is precisely cut so as to be located between the disc and the end plate, the inner surface of the tension device and the screw-coupled fastening device is located on the inner side of the disc and the end plate, so that the number of the tension muscles All tensile muscles remain the same, regardless of length, so that the tensile force applied to each tensile muscle is uniform. Since the tensile force is uniform, eccentricity does not occur in the tensile muscles, so it is possible to produce structurally stable poles, which is an efficient and economical useful invention.
