Description

[Detailed description of the invention] The present invention is a capsule for rust prevention and reinforcement of fastening bolts, more specifically a capsule for rust prevention and reinforcement of hexagonal bolts, square nails, large needles, etc. (hereinafter referred to as fastening bolts) used for concrete sleepers or wooden sleepers. (hereinafter simply referred to as capsule).

Tightening bolts are used as a general method for fastening rails or tie plates to sleepers, but when fastened with these fastening bolts, the material deterioration of the sleepers due to dynamic loads from trains and aging, especially concrete. In the case of sleepers, the material deteriorates in the embedded plugs, and in the case of wooden sleepers, the Omachi holes (hereinafter referred to as bolt holes) deteriorate, and the fastening bolts develop rust, which causes the fastening force between the rail and the sleepers to loosen, causing track deviation. It often progresses.

In addition, the deterioration of the material of the bolt holes of the sleepers accelerates the deterioration of the sleepers, which causes disadvantages in terms of track strength and track maintenance economics.

In view of this problem, the inventors of the present invention have conducted extensive research, and as a result, they have put an adhesive containing a rust preventive and/or preservative into the capsule, and utilized the fixing action of the fastening bolt inside the bolt hole. Break! By spreading the adhesive between the fastening bolts and sleepers, you can not only strengthen the fastening bolts against rust with a simple operation, but also prevent material deterioration in the bolt holes, and maintain the relationship between the rails and sleepers for a long time. After learning that it was possible to maintain the fastening force of 1, the present invention was completed.

The present invention consists of a container that is filled with an adhesive containing a rust preventive agent and/or a preservative, and that can be inserted into a fastening bolt hole of a sleeper, etc., and the wall of the container is fastened by inserting it into the bolt hole. A molded sealing member that can be broken by the pressing force of a bolt and has a sealing area sufficient to prevent adhesive from flowing out or scattering from the bolt hole when the container is broken is provided on the upper or lower end surface of the container. An object of the present invention is to provide a capsule for rust-proofing and reinforcing fastening bolts, which is characterized by:

Common adhesives such as single-wave moisture-curing adhesives, two-component adhesives, solvent solution adhesives, latex adhesives, and emulsion adhesives can be used, but performance and
A single-wave moisture-curing adhesive is preferred from the viewpoint of workability.

In particular, urethane-based, especially asphalt urethane or tar urethane-based single-wave moisture-curing adhesives are particularly preferred since they also have a rust-preventing effect.

The adhesive is blended with a rust preventive and/or preservative depending on the type of sleeper.

As the rust preventive agent, most of those commonly used as rust preventive pigments and rust preventive additives can be used, but in the case of adhesives having a rust preventive effect, addition may not be necessary.

The preservative may be one that is generally used as a wood preservative, but a combination of a water-soluble salt type preservative and an oily preservative is particularly preferred because it has a large preservative effect in a humid environment. .

The formulation of preservatives is particularly effective for wooden sleepers.

In addition, in order to enhance the effect of holding fastening bolts,
Silica sand, diamond sand, and glass powder may be blended.

Adhesive containers must be easily destroyed by screwing or driving fastening bolts into the fixing holes, but must not be damaged during transportation, and should also prevent contents from evaporating and outside air from entering. Shielding properties are also required, such as aluminum-laminated plastic film containers such as aluminum-laminated polyethylene, round plastic containers such as polyvinyl chloride, polyvinylidene chloride, Teflon, and polyethylene, polyvinyl chloride, vinyl chloride, acetic acid, and vinyl copolymer. Examples include glass containers coated with a tough resin such as fused resin, but in short, it is best to choose the material and wall thickness by taking into consideration factors such as breakage resistance during transportation and possibility of breakage during construction.

A molded seal member is attached to one end of the adhesive container to prevent the adhesive from flowing out or scattering from the bolt hole when the container is broken.

The sealing member may vary depending on the type of bolt hole.

For example, in the case of concrete sleepers, it is sufficient to have a cross-sectional area that seals the drain hole communicating with the bolt hole in order to fit the fastening bolt into the bolt hole, while in the case of wooden sleepers, the bolt hole should have a large needle, etc. is driven in, so a sealing area that is at least approximately equal to the cross-sectional area of the bolt hole is required.

The sealing member is preferably made of rubber or soft plastic, and may be formed integrally with the cylindrical container using polyethylene, polypropylene, or the like.

Further, it may also be used as the lid of the container.

The capsule according to the present invention is inserted into the bolt direction before the fastening bolt is inserted into the bolt hole.

In particular, in the case of concrete sleepers, if the bolt holes are not constant and are too deep, the container containing the adhesive may not be destroyed when the fastening bolt is inserted.

In order to prevent this, it is preferable to adjust the capsule position of the bolt Omukai according to the depth of the bolt hole.

For example, the height of the adhesive container can be adjusted by interlocking the adhesive container and the molded seal member.

Furthermore, the amount of screwing of the capsule may be adjusted by providing a protrusion on the outer periphery of the molded sealing material that can be fitted into a bolt hole.

Hereinafter, specific examples of the present invention will be explained with reference to the accompanying drawings.

FIG. 1 is a cross-sectional view of a capsule according to the present invention. In the case of a rust preventive agent for iron and wooden sleepers, a single-wave moisture-curing adhesive 2 containing a preservative is used, for example, in a cylindrical container made of polyvinyl chloride. (Wall thickness 0.57Ir!n, diameter 15 x height 7orrgI
t) It is stored in 1.

A plate-shaped molded seal member 3 made of soft plastic is fixed to the lower end of the cylindrical container 1.

In the case of concrete sleepers, the capsule is inserted into a bolt hole 10 of a hexagonal bolt with the molded seal member 3 side facing downward, as shown in FIG. The punch hole 11 is closed.

After that, when the hexagonal bolt 12 is fitted from the top of the bolt hole 10, the tip of the bolt begins to press the top end of the cylindrical container 1 downward, and when it descends to a certain extent, the container wall is destroyed and the adhesive inside is poured into the bolt hole 10. Fill up.

Furthermore, when the hexagonal bolt 12 is lowered, the adhesive 2 spreads between the bolt hole 10 and the hexagonal bolt 12 (see FIG. 12).

Note that FIG. 13 shows a state in which the rail R is attached to the sleeper T via the fastening spring 13.

In the case of concrete sleepers, the molded seal member 3 is mainly intended to close the drain hole 11, so if the molded seal member 3 is formed into a conical shape as shown in FIG. 2, it will fit into the drain hole. This is preferable because it is easy.

Furthermore, as shown in Fig. 3, if the container 1 is formed into a sausage shape by using a plastic cylindrical film and sealing both ends with clasps 1a, the container wall can be easily made flexible and break during transportation. In addition, the capsules are easy to manufacture and cost-effective.

Furthermore, in concrete sleepers, the depth of the bolt holes may not be constant, so it is best to be able to adjust the height of the capsule so that the capsule container will not be destroyed when the hexagonal bolt is inserted into the bolt hole. .

Therefore, as shown in FIG. 4, a nail-shaped protrusion 1b is provided at one end of the adhesive container 1, and a female threaded hole 3a passing through the center of the molded seal member 3 is provided, and the protrusion 1b is inserted into the female threaded hole 3a. may be combined.

In addition, as shown in Fig. 5, an aluminum-laminated plastic cylindrical film is used as the adhesive container, one end 1c is tightly wound, and the other end is provided with a nail-shaped protrusion 1d similar to that shown in Fig. 4. A female screw hole 3b that does not penetrate therethrough may be provided in the center of the seal member 3, and the projection 1d may be intertwined within the female screw hole 3b.

Furthermore, as shown in FIG. 6, a flow-like projection 4 may be provided on the outer periphery of the molded seal member 3, and the projection 4 may be engaged with a threaded portion of a bolt hole.

In this case, as shown in FIGS. 7 and 8, a (+) or (=) shaped driver groove 5 is provided at the upper end of the adhesive container 1.
A and 5b may be provided with a protrusion 5 that can be screwed in with a screwdriver, or as shown in FIGS. The member 6 may be provided in a protruding manner, and the grip member 6 may be held to be screwed in.

On the other hand, in the case of wooden sleepers 20, unlike concrete sleepers, a large needle for driving is used, so a preliminary fixing hole 21 with a smaller cross section and shallower depth than the large needle, etc. is drilled in advance. The capsule according to the present invention is inserted into the hole 21 (17th medical examination diagram).

The capsule is preferably inserted into the fixing hole 21 with the molded seal member 3 facing upward (see FIG. 18).

In this way, when the large needle 22 is driven into the fixing hole 21, the adhesive container 1 is easily destroyed and the internal adhesive 2 is scattered, but the molded seal member 3 prevents it from scattering outside the fixing hole. It is sealed without any problem and is spread between the large needle and the fixed hole (first
(See Figure 9).

Therefore, the large needles are not only reinforced and firmly fixed to the wooden sleepers by the adhesive, but also the rust preventive agent and preservative in the adhesive prevent the large needles from rusting and the material of the main sleeper parts that come into contact with the large needles. Prevents deterioration and maintains the fixing strength of the large needle over time.

In addition, the solid line part in the wooden sleeper 20 shows the penetration of the preservative.

The rust-proofing reinforcing capsules used for wooden sleepers may have the same capsule structure as concrete sleepers, but in order to effectively utilize the driving action of large needles, etc., it is more preferable to configure them as follows. .

FIG. 14 shows a capsule in which a container 1 is made of a glass material and its opening is sealed with a molded sealing material 3 that also serves as a lid. This is because it mixes into the adhesive and increases the frictional force after the adhesive hardens, making it difficult for the large needle to come off.

In this case, to prevent container damage during capsule transportation,
It is preferable to cover the entire capsule with tough resin 7 (
(See Figure 15).

Further, as shown in FIG. 16, it is preferable to form a concave groove in the center of the molded seal member 3 so that the large needle can be bent or penetrated by its tip when driving in, since the sealing effect is great. .

Although various preferred specific examples have been described above with reference to the accompanying drawings, the present invention is not limited to the above specific examples.
Various modifications can be made without departing from the gist of the present invention.
