Description
The present invention relates to a rail fastening device made of a synthetic resin material and integrated with a metal reinforcement material having improved economy, efficiency, durability and homogeneity.
Generally, the structure of the track is composed of a bedrock, a bed, a sleeper, a rail and a line structure. In the structure of such a track, a road bed is a group of gravels formed on a bedrock, and is generally classified into a general road, a secondary road, a concrete road, and the sleeper is laid beneath the rail to firmly position and hold the rail in place, Which are distributed over a wide range of road loads, are classified into wooden sleepers and concrete sleepers. The rails are fixed by a fastening device with screw spikes and spring clips to the concrete sleeper or concrete slabs. These fastening devices are basically equipped with elastic pads to reduce noise or vibration transmitted from the wheels to the rails during train operation .
Such a conventional technique is disclosed in Korean Patent Laid-Open Publication No. 10-2010-0126699 (hereinafter referred to as Patent Document 1).
Patent Document 1 includes a sleeper preformed with concrete, and on the free upper end portion of the sleeper, two stop portions separated from each other in the form of a hump-like ridge portion are formed. On each of the surfaces of the stop parts facing each other, there is a stop surface extending substantially parallel to each rail. In this way, the stop provides a lateral boundary of the receptacle extending therebetween in a direction across the rail, the flat base of the receiving port forming a substrate, and rails being laid on the substrate.
The support element is supported on the side surface of the guide plate on the side farther from the rail and mounted on the stopper. The guide plate supports the guide plate, And a tensioning clamp supported on the guide plate and having at least one spring arm for supporting the base of the rail and having a support surface associated with the guide plate and a support surface associated with the support, And a fastening bolt for fastening the tension clamp.
The rail fastening apparatus according to the above-described Patent Document 1 attaches and fixes the rail to the concrete sleepers through such a construction. Particularly, regarding the transverse force generated when the train travels on the rail, The guide plates disposed on both sides thereof are supported, and the guide plates can be laterally supported on the respective stop portions through the support elements.
However, the rail fastening apparatus of Patent Document 1 has a problem that it is difficult to manufacture a sleeper and it is necessary to spend an excessive amount of money because two fasteners spaced apart from each other in the form of a hump-like ridge are formed on the railroad tie itself.
The rail fastening device according to the related art is provided with a stopper formed in the railroad tie itself so as to stably support a transverse force generated when the train travels on the rail, The load is applied to the stop portion without being attenuated in the middle, so that the sleeper itself may be damaged. In the event that the sleeper itself is damaged, it is necessary to perform a complicated restoration operation .
In order to solve such a problem, Korean Patent Registration No. 10-1530965 (hereinafter referred to as Patent Document 2) has been proposed.
The above-mentioned
(Patent Document 1) KR10-2010-0126699 A Rail fixing system and rail fixing device for fixing rails on a substrate
(Patent Document 2) KR10-1530965 B1 Rail fastening device with shear load induction enclosure
However, in the above-described
In order to solve the above-mentioned problems, a rail fastening device incorporating a metal reinforcement according to the present invention has a metal reinforcing member formed by insert injection at a position expected to be damaged by lateral load and axial load by contacting with a guide plate, It is an object of the present invention to provide a rail fastening device in which a metal reinforcement material is integrally assembled so as to improve workability while reducing weight and minimize damage caused by warpage, deformation and abrasion at a position at which breakage is expected.
Another object of the present invention is to provide a metal stiffener having a structure in which a bottom contact member and a side contact member are integrally formed and spaced apart from each other by a predetermined distance and then connected through first and second connecting members, The bottom plate and the side support portion can be firmly coupled to the bottom plate and the side support portion to improve the durability, and the bottom plate and the side support portion can be integrated to prevent deformation and cracks from occurring even when a lateral load is generated.
Another object of the present invention is to provide a side reinforcement member for supporting a side support member constituting a metal reinforcement, the side reinforcement member being embedded in a side support portion, minimizing breakage of the side support portion when a lateral load and axial load are generated, Thereby improving the durability of the battery.
Another object of the present invention is to provide a floor surface contact member and a side surface contact member having a chamfer formed in the bottom contact member and the side contact member constituting the metal stiffener so that the metal stiffener is firmly coupled So as to improve durability.
The present invention relates to a method of manufacturing a metal plate by forming a metal reinforcement through insert injection at a position where damage is expected by lateral load and axial load by contacting with a guide plate to improve workability while reducing the weight by making the entire material of synthetic resin material, Damage due to bending, deformation and abrasion can be minimized.
In addition, the metal reinforcement may be formed by integrally forming the bottom contact member and the side contact member integrally with a predetermined distance therebetween, and then connecting the first and second connecting members through the first and second connecting members. The bottom plate and the side support portion can be integrated to prevent deformation and cracks from occurring even when a lateral load is generated.
Further, since the side contact member reinforcing members for supporting the side supporting portions constituting the metal reinforcement are embedded in the side supporting portions, breakage of the side supporting portions can be minimized when the lateral and axial loads are generated, and durability of the side supporting portions can be improved have.
In addition, a bottom surface coupling hole and a side coupling hole in which a chamfer is formed in the bottom contact member and the side contact member constituting the metal reinforcement are formed to maintain the state where the metal reinforcement is firmly coupled at the bottom plate and the side support portion, thereby improving durability It is a useful design that can be made.
