Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a silo repair method for grass, which prevents corrosion of the inner surface of a silo for grass for housing grass for livestock breeding, and a grass silo formed by using the repair method. Regarding silos.

[0002]

BACKGROUND OF THE INVENTION Grass silos are generally assembled locally because of their large size. When assembling the silo,
The inner wall is covered with a rust-proof enamel (glass glaze burned at high temperature), and the inner wall of the tubular peripheral wall is curved inward in an arc shape and multiple bolts and nuts are used. It is formed by joining together.

By the way, when the iron plate for forming the peripheral wall of the silo is curved inward in an arc shape, a crack is formed in the vitreous enamel covering the inner peripheral surface of the iron plate, and the iron plate of the peripheral wall body is exposed in the crack. It will be in the state of doing.

Further, when grass is put into the silo or taken out of the silo, hard grass and the like in the grass strongly rubs the inner peripheral surface of the peripheral wall of the silo, so that the inner peripheral surface of the peripheral wall of the silo is rubbed. Peel off the covering enamel. Then, the iron plate of the peripheral wall body of the silo is exposed on the inner peripheral surface of the peripheral wall of the silo.

About 40-60% of grass is stored in silos
It also contains water. At the same time, the grass contained in the silo is fermented in the silo and the internal temperature becomes high.

Therefore, iron rust easily and quickly occurs on the iron plate portion exposed on the inner peripheral surface of the peripheral wall of the silo, due to grass containing a large amount of water or grass fermented at high temperature. And
The iron rust corrodes the iron plate portion around it, making the iron plate forming the peripheral wall body brittle. As a result, when corrosion of the peripheral wall body progresses extremely, the peripheral wall of the silo collapses and a serious accident occurs.

Therefore, conventionally, when the iron plate of the main body of the peripheral wall is exposed to the inner peripheral surface of the peripheral wall of the silo as described above, various kinds of rust preventive plastics or the like are formed on the inner peripheral surface of the peripheral wall. The coating agent is applied to cover the iron plate portion of the peripheral wall main body exposed on the inner peripheral surface of the peripheral wall of the silo with the coating agent to prevent the iron plate portion from rusting and corroding the iron plate.

[0008]

However, by simply covering the inner peripheral surface of the peripheral wall with a coating material such as plastic for rust prevention as described above, the grass is put into the silo or the grass is taken out of the silo. When the surface of the coating agent covering the inner circumferential surface of the silo was rubbed with grass, the coating agent was easily separated from the inner circumferential surface of the circumferential wall.

Specifically, the inner peripheral surface of the peripheral wall of the silo is covered with the enamel made of smooth glass material as described above. Therefore, the coating agent applied to the inner peripheral surface of the peripheral wall covered with the enamel does not firmly stick to the inner peripheral surface of the peripheral wall and is easily peeled off from the inner peripheral surface of the peripheral wall. for that reason,
When the surface of the coating was rubbed with grass, the coating easily separated from the inner peripheral surface of the peripheral wall of the silo and fell off.

Then, the iron plate of the peripheral wall body was exposed again on the inner peripheral surface of the peripheral wall of the silo, and the iron plate portion was rusted and the periphery of the iron plate portion was corroded.

The present invention has been made in view of the above problems, and it is possible to continue to surely cover the inner peripheral surface of the peripheral wall of the silo with the rust preventive coating agent so as not to be easily peeled off. An object of the present invention is to provide a method of repairing a silo for grass (hereinafter referred to as a repair method) that can be performed, and a silo for grass (hereinafter referred to as a silo) formed by using the repair method.

[0012]

In order to achieve the above object, a repairing method of the present invention is a method for repairing a silo peripheral wall in which a peripheral wall body is formed of an iron plate, such as iron rust on the inner peripheral surface of the peripheral wall. The step of removing dirt, the step of applying a layer of elastic rust-preventive coating to the inner surface of the circumferential wall from which the dirt has been removed without gaps, and a stainless steel plate on the inner surface of the circumferential wall coated with the coating Step of tightening, inserting the bolt protruding from the inner peripheral surface of the peripheral wall into the bolt insertion hole provided in the stainless plate, screwing a nut at the tip of the bolt and tightening the stainless plate, A step of fixing the coating surface to the inner peripheral surface of the peripheral wall in a state of being adhered to the surface of the coating material by using elasticity of the coating material, and rust prevention in a gap opened at an end edge of the stainless plate stretched on the inner peripheral surface of the peripheral wall With a coating agent and fill the gap with the coating agent With cunning, it is characterized by comprising the step of covering their surface with a coating agent by a coating agent for rust in the bolt tip and the nut surface exposed to the stainless steel plate top surface is coated, respectively.

The silo of the present invention is a silo having a peripheral wall body formed of an iron plate, in which stains such as iron rust on the inner peripheral surface of the peripheral wall of the silo are removed, and the inner peripheral surface of the peripheral wall has a resilient rust-proof coating. Along with applying the agent in a layered manner, a stainless plate is stretched around the inner peripheral surface of the peripheral wall coated with the coating agent, and a bolt protruding from the inner peripheral surface of the peripheral wall is inserted into a bolt insertion hole provided in the stainless plate, The stainless steel plate is fixed to the inner peripheral surface of the peripheral wall in a state in which the nut is screwed to the tip of the bolt and tightened, and the back surface of the stainless steel plate is brought into close contact with the surface of the coating material by using the elasticity of the coating material. , A rust preventive coating agent is filled in a gap opened at an edge of the stainless steel plate extending on the inner peripheral surface of the peripheral wall and the gap is sealed with the coating agent, and a bolt tip and a nut exposed on the upper surface of the stainless steel plate Coating for rust prevention on the surface Is characterized by covering their surface with a coating agent is applied, respectively.

[0014]

In the silo repaired by the repair method consisting of the above steps, or in the silo having the above-mentioned structure, the surface of the coating agent for rust prevention applied in layers on the inner peripheral surface of the peripheral wall of the silo is covered with a stainless steel plate to prevent rust prevention. The surface of the coating material is protected by a stainless plate.

Therefore, when the grass is put into the silo or the grass is taken out from the silo, the coating material covering the inner peripheral surface of the peripheral wall of the silo is rubbed directly with the hard grass or the like in the grass, The coating agent does not peel off from the inner peripheral surface of the silo peripheral wall. In other words, the tough stainless steel plate surface stretched around the inner peripheral surface of the silo is not directly rubbed by the grass, and the coating material inside the stainless steel plate is not directly rubbed by the grass.

At the same time, a stainless steel plate fixed to the inner peripheral surface of the silo peripheral wall by using bolts and nuts is used so that the coating material is firmly fixed between the stainless steel plate and the inner peripheral surface of the peripheral wall of the silo so as not to be easily peeled off. Sandwiched between.

For this reason, the inner peripheral surface of the peripheral wall of the silo is continuously covered with the coating agent for a long period of time, and the iron plate portion of the peripheral wall main body exposed on the inner peripheral surface of the peripheral wall of the silo is rusted to cause the iron plate. Corrosion around the part is prevented.

The inner peripheral surface of the peripheral wall of the silo is covered with an elastic coating material.

Therefore, when the stainless steel plate is fixed to the inner peripheral surface of the peripheral wall of the silo using the bolts and nuts, even if the surface of the coating agent applied in layers on the inner peripheral surface of the peripheral wall has irregularities, the surface of the coating agent is not covered. The back surface is in close contact with the stainless plate and the inner peripheral surface of the peripheral wall of the silo without any gap.

Moisture and humidity in the grass penetrate between the stainless steel plate and the coating agent and between the coating agent and the inner peripheral surface of the peripheral wall to rust the iron plate portion of the peripheral wall body exposed on the inner peripheral surface of the peripheral wall. Occurs, and corrosion around the iron plate part is prevented.

The stainless steel plate is excellent in corrosion resistance and is tough.

Therefore, it is possible to prevent the surface of the coating agent from being exposed inside the silo, because the stainless steel plate rusts and decays due to moisture in the grass or heat generated by the grass, or the stainless steel plate is crushed by being rubbed by the grass and crushed. It
