Description

A fixing member for a concrete insert being used in railroad tie}

The present invention relates to a fixing device before spiral reclamation for iron bi-block railroad ties, and prevents departure before reclamation during concrete placement for railroad ties and increases hardness, strength, and elasticity during train operation. It relates to a fixing device.

In general, sleepers are arranged at appropriate intervals on a ballast, and rails are laid and settled thereon, so that the gage, which is the distance between the rail and the rail, is accurately maintained, and the train load applied to the rail is controlled through the ballast. It refers to wood or concrete delivered to the roadbed.

Wood sleepers have been mainly used, but there are defects such as decaying and bursting or warping, and there has been a shortage of forest resources after World War II, and concrete sleepers have been used as substitutes. Concrete sleepers include RC sleepers (reinforced concrete ties) and PC sleepers (prestressed concrete ties). PC sleepers are superior among them, so PC sleepers are mostly used now.

The vibration generated by the friction between the rails and the wheels when driving a train causes vibration and cracks, which adversely affects the durability and safety of the structure, and causes noise and vibration pollution to the living environment around the railroad rails. There are constant complaints in the country. For this reason, technologies related to vibration and noise of railroads are constantly being developed as interest in the environment increases.

Railroad sleepers play a role in maintaining the spacing of rails and transmitting the load of the train. In the past, wooden sleepers were used a lot, but in modern times they have been changed to concrete sleepers, and concrete sleepers transmit vibrations, pressures and loads acting on trains. Therefore, the train can be operated safely by preventing departure.

Conventional Patent Publication No. 10-2005-0087052 relates to a pre-embedded fixing device for railroad sleepers. The device for fixing the fixing device before purchase in the process of forming a sleeper using a sleeper maker has a very complex structure. And because of too many members, installation was difficult and costly.

Conventional Patent Publication No. 10-2006-0106543 relates to before embedding for concrete sleepers. A spiral triangular screw is formed on the outer circumferential surface before embedding, and by increasing the contact area between the sleeper and before embedding, it is possible to improve adhesion, increase lateral resistance and pullout force. There is a problem in that the water inflow prevention jaw protruding in a circular shape at the upper end is too low to allow water to flow into the interior.

In addition, the conventional holder before embedding is made of a urethane material, resulting in high cost and poor durability.
