Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a pseudo-wood utility pole mainly used in scenic areas and the like.

In the Kansai region, the Ancient Capital Preservation Law is applied to two districts, Nara and Kyoto, but in order to preserve the environment, these areas are designated as scenic areas and structures must be built to avoid destroying the current environment. is regulated. For this reason, the current cosiclete utility poles used as power distribution equipment are too conspicuous, and water poles with a short service life are inevitably used. costs.

In view of this point, an object of the present invention is to provide a method for manufacturing a pseudo-wood telephone pole using cosiclete at a low cost by a simple method as a substitute for a wooden pole.

To explain the embodiment of the present invention with reference to the drawings, (1) is a bark board made of synthetic resin, where the bark of a real tree is spread on a flat surface, resin for molding is poured on it, and after it hardens, it is attached to a tree. It is made by peeling and gluing the skin.

After cutting this bark board (1) according to the length and length of the pseudo-wood utility pole to be manufactured and applying a mold release agent, the bark board (1)
Curve it into a U shape with the molded surface where the wood grain appears on the inside, and push the lower half into the semicircular gutter-shaped lower mold frame (2),
Attach accessories for the lower formwork as appropriate. This is the lower formwork (2
) also has the purpose of preventing movement of the bark board (1). In addition, when cutting the bark board (1), it is necessary to take into account the shrinkage of the bark board (1),
Also, when pushing the bark board (1) into the lower formwork (2), it is important to do so so that the U-shaped curved tip protrudes evenly above the lower formwork (2). It is.

Next, a reinforcing bar basket (3) is placed inside the lower formwork (2) with a predetermined distance between it and the lower half of the bark board (1). After arranging the reinforcing bar basket (3), the tip of the bark board (1) protruding upward from the lower formwork (2) is curved, and a predetermined interval is left above the reinforcing bar basket (8). , overturn the semicircular gutter-shaped upper formwork (4), fasten the upper and lower formworks (4) and (2) together with appropriate bolts (not shown) to assemble the frame, and then attach the upper formwork side accessories. Attach. In this case, the part of the bark board (1) that protrudes upward from the lower formwork (2) has a length that corresponds to the inner circumference of the upper formwork (4), so this part Be careful not to get caught between (4) and (2).

In such a case, the bark board (1) deforms along the inner peripheral surface of the upper formwork (4), and when the lower formwork (2) and the upper formwork (4) are joined, the bark board (1) completely upper and lower formwork (4) and (2)
It is pasted on the inside of the.

Next, cycrete is injected into the assembled molds (2) and (4) and centrifugal molding is performed by a known method. After molding, it is cured to solidify the cosicrete.

Next, after removing the accessory attachment fittings attached to the upper and lower formworks (4) and (2), the bolts fastening the upper and lower formworks (4) and (2) are removed to remove the mold.

Since the outer periphery of the demolded product is soaked in the bark board (1), set the seam of the bark board (1) to -F, and roll the product from one side of the seam to cover the entire circumference with the bark board. Peel off. The bark board (1) is removed from the product with the bark board (1) removed.
) remains, so we repaired and finished the other necessary parts, and in the case of colored poles, we applied a sealer finish, and then, at the end of the day, we installed + cep at the base of the finished product. shall be.

In the above embodiments, cosicrete was filled into the mold by centrifugal force forming, but the present invention is not limited to this, and cosicrete can also be filled into the mold by a filling method.

However, in this case, the formwork is doubled with a reinforcing cage (3) interposed therebetween, and cosiclete is filled between them.

The artificial wood telephone pole manufactured as described above has a wood grain-like pattern on its surface, so it looks like a wooden pole at first glance, and when used in the following places, there is no risk of destroying the surrounding environment. Expected to be effective.

0 Environmental conservation areas (mainly mountainous areas) ○ Places in parks that require an aesthetic appearance ○ Areas with particularly large numbers of trees in urban areas ○ Other areas that require an aesthetic appearance As described above, the present invention is designed to spread bark on a flat surface, A resin for molding is poured onto it, and after it hardens, it is peeled off from the bark to make a bark board.The bark board is cut into a predetermined shape and size and curved into a U-shape, and the lower half is shaped like a gutter. At the same time, a reinforcing bar cage is placed inside the lower half of the bark board at a predetermined distance from the lower half of the bark board, and while the upper half of the bark board is curved, the reinforcing bar cage is inserted into the lower half of the bark board. A trough-like upper formwork is placed over the lower formwork at a predetermined distance above the lower formwork, the upper and lower formworks are fastened to each other to form a frame, and then Sifrito is injected into the frame to form reinforcing bars. The manufacturing method is extremely simple, as it relates to a method for manufacturing a pseudo-wood telephone pole, which is characterized by filling and molding the inside and outside surfaces of a basket, leaving the upper and lower formwork after curing and solidifying, and then peeling off the bark board. In addition, compared to the conventional method of making a mold of a fake tree directly from raw wood, it is possible to use only the bark of the tree, spread the bark on a flat surface, and pour resin on top of it to make the mold. Bark boards of arbitrary width and length can be obtained depending on the diameter and length of the artificial tree, and a pseudo-wood telephone pole of a desired size can be easily manufactured. In addition, the fake wood utility pole manufactured using this method has a very beautiful appearance, with one vertical red joint between the bark boards. Since the thickness of the bark board can be changed freely, the manufacturing cost of the bark board is also very low, and therefore the product cost is not much higher than that of a normal cosiclete utility pole.
