Description

Manufacturing device for electric pole

The present invention improves the horse-side structure of the pole pole manufacturing apparatus using centrifugal casting for the manufacture of reinforced concrete poles, and it is possible to arrange the tensile rods according to the design value according to the cost reduction and the increase in the design load. The present invention relates to a pole pole manufacturing apparatus capable of producing high pole poles.

Generally, a pole is a cylindrical shape with a gentle gradient and is manufactured in various lengths from 7 to 17m. The end buried in the ground is called a circle and the opposite end is called. These poles are made of concrete as a base material, but is made of a structure that increases the strength of the pole by molding a frame consisting of a tension bar that is disposed in the longitudinal direction and the iron wire attached to the tension bar by welding.

1 is a cross-sectional view and a partially enlarged view showing a configuration of a conventional pole manufacturing apparatus, Figure 2 and Figure 3 is a view showing a fastening structure of the tension muscles applied to the conventional pole production apparatus.

In the conventional electric pole manufacturing apparatus in Figure 1 is a divided structure in which the die 20 is opened and closed.

The formwork 20 is equipped with a disc plate 30 to form a sphere 30 of the electric pole 10 on one side, and to maintain a constant interval with the disc plate 30 to mount the circle tension plate 32 and A spherical sphincter fixing plate 34 which is fastened in a state where one side of the tensile muscle 64 penetrates is mounted on the bottom surface of the spherical tension plate 32.

Formwork 20 is equipped with a horse plate 40 to form a horse 14 of the pole 10 on the other side, the horse plate 40 to be coupled to the tension axis 50 is constant with the horse plate 40 Mounting and maintaining the spacing is mounted on the top surface of the horse tension plate 42 is a horseshoe tension fixing plate 44 which is fastened in a state that the other side of the tensile muscle 64 penetrated. The tension shaft 50 is bolted to connect with an external tensioner and is installed to be rotated by the fastening force of the nut 52 in the state of penetrating the copper plate 46 fastened to the upper side of the formwork.

The horse plate 40, the horse tension plate 42, the sphere plate 30, the sphere tension plate 32 forms a hole through which both sides of the tensile muscles 64 arranged in a circle.

Although not shown in the drawing, the outer periphery of the formwork 20 includes a plurality of rings capable of receiving rotational force in contact with the rotating roller.

In addition, the spherical tendon root fixing plate 34 and the spherical tendon root fixing plate 44 are combined in the state where the tensile muscle 64 penetrates as shown in FIGS. 2 and 3 so as to have a bearing force. Peanut-shaped fastening holes 36 of different diameters are formed.

The tension root 64 forms a head 66 so that both ends enter and engage the small diameter 38 inserted into the large diameter 37.

Looking at the work process of such a conventional mold device,

① First process

After placing a plurality of tensile muscles 64 cut about 400mm ~ 500mm longer than the length of the pole 10 in the longitudinal direction of the pole 10, and wound around the spiral wound around the wire to form a frame, The head 66 is formed by heating and pressing both ends of the tension root 64 arranged in the longitudinal direction in the frame.

② Second process

A mold release agent is applied to the formwork 20, and both sides of the tensile muscle 64 pass through the horse plate 40, the horse tension plate 42, the sphere plate 30, and the sphere tension plate 32. The head 66 is fastened to the fastening holes 36 of the spherical sphincter fixing plate 34 and the spherical sphincter fixing plate 44, and the frame formed in the first step is remodeled to the formwork 20. Settle down.

③ Third process

When the concrete is added into the formwork 20, the tensioning muscle 64 is pulled tightly through the tensioner so that there is no deformation of the entire frame, and then the concrete is introduced into the formwork 20 and the formwork 20 is rotated in the centrifuge in a closed state. It is to make the inner hole to become the thickness of the prescribed pole 10.

At this time, the tension root 64 is provided with a tensile force that is just to maintain a straight line with the tensile axis 50, when the tension is excessively tensioned the tension muscle 64 is stretched head 66 and the head 66 Care should be taken that the adjacent surface of the caught small diameter 38 is retracted to release the tensioned state.

④ 4th process

Steam curing is performed by the boiler so that the concrete of the pole 10 has a predetermined demoulding strength.

⑤ 5th process

After cutting the tensile muscles 64 using a welding rod between the horse plate 40 and the horse tension plate 42 and between the sphere plate 30 and the sphere tension plate 32, only the electric pole 10 was transferred. The electric pole 10 is completed by performing fine cutting and natural curing of the tensile muscles 64 remaining on the spherical sphere 12 side and the horse sphere 14.

However, the conventional electric pole manufacturing apparatus cuts about 400mm ~ 500mm longer than the length of the pole 10 in order to tension the tension root 64, the problem of causing the cost increase as much as the excess length of the tensile muscle 64 there was.

Another problem is that the fastening hole 36 has a nut shape, and the head 66 of the tension root 64 enters the large diameter 37 of the fastening hole 36 and then moves to the small diameter 38 so that the head 66 is moved. The structure of the large diameter 37 side is opened by the structure supported by the adjacent surface of the small diameter 38, and the shape of the horseshoe 14 of the electric pole 10 becomes bad.

That is, when the head 66 of the tensile muscle 64 passes through the large diameter 37 of the horseshoe tendon fixation plate 44 and rotates the horseshoe tendon fixation plate 44 slightly, the head 66 has a small diameter 38. And the tension root 64 is constrained by engaging the adjacent surface of the small diameter 38.

As such, since the large diameter 37 is opened, the concrete or water constituting the electric pole 10 leaks through the gap, so that the horseshoe shape of the product is poor.

In order to solve this problem, if the large diameter (37) exposed by using a separate member to block the process is complicated.

In addition, in the case where the fastening hole 36 restraining the tension muscle 64 tensions the tension muscle 64 in a structure forming a clearance between the large diameter 37 and the small diameter 38, the tension muscle 64 is centered. In particular, the flow of the horseshoe plate tensile muscle fixation plate 44 is generated, and the shape of the horseshoe 14 of the pole 10 becomes poor.

Another problem is that when the design load of the pole 10 is increased, it is impossible to arrange the tension root 64 on the side of the horse 14 having a relatively small diameter with respect to the diameter of the pole 12 of the pole 10.

That is, when the length of the pole 10 is 16m, the design load of the pole 10 is 1300kg, the diameter 14 of the horse ball 14, 12 tensile muscles 64 having a diameter of 14mm of the tensile muscle 64 is required, and The spacing between the tension roots 64 has a design value of 40.58 mm.

However, the fastening hole 36 formed in the conventional horseshoe tendon fixing plate 44 has a structure of a large diameter 37 and a small diameter 38, that is, lengths of both sides of the large diameter 37 and the small diameter 38, ie, Twelve fastening holes (36) for the arrangement of twelve tensile muscles (64) in which the range angles of both large and small diameters (37) and small diameters (38) from the central axis of the rectus muscle fixing plate (44) satisfy the above design values. Formation area of the can not be secured and manufacturing the pole 10 was not possible according to the design load.

The present invention is to solve the above problems, an object of the present invention is to improve the horseshoe side structure of the manufacturing apparatus using centrifugal casting for the production of the reinforced concrete structure of the poles tension force to the horse plate forming the horseshoe poles It is to provide a manufacturing apparatus of a pole for fastening one side of the tension muscle to the horse plate.

Another object of the present invention is to tighten the tension muscles of the horse plate by using a bolting method, the effective area for fastening the tension muscles on the horse plate is relatively increased, and the pole can be stretched by the tightening of the tight bolt method It is to provide a manufacturing apparatus.
