The present invention relates to a soundproof railroad rail and a connection structure thereof, and more particularly, to a soundproof railroad rail and a connection structure having an improved structure to prevent noise during driving of a train and to make the rail more rigid. .

In general, train rails have been reciprocated by rails that are fastened to sleepers made of wood or concrete. However, as described above, in order to effectively resilient to the load generated on the sleeper of wood or concrete material formed in the lower part of the rail according to the running of the train to reduce the vibration transmitted to the fastening member and the sleeper, the protection of the image due to the vibration and the train Many studies have been conducted to reduce environmental pollution due to noise and noise.

For example, Korean Utility Model Registration No. 20-0273446 reduces vibrations and noise generated when a train runs due to stepping by spaces formed at rail connecting parts in consideration of expansion and contraction of rails due to temperature differences. As for the purpose, the wedge insertion groove is provided at the opposite end of the rail and the wedge is inserted into the wedge insertion groove, and the wedge is formed in the wedge insertion groove of one rail so that the wedge insertion groove of one rail is inserted therein. The wedge insertion groove of the opposite rail discloses a technology related to the vibration and noise prevention structure of the railway rail, which is improved in the structure so that the flow insert is inserted.

Publication No. 02772559 describes dust-proof threaded spikes fastened on railroad concrete sleepers and direct connections.

Publication No. 20-0301005 is provided with a plurality of coupling grooves in the longitudinal direction to be fixed by bolts and nuts after the fixing plate on both sides of the end of the rail, and cross and abut each other in the thickness direction of the rail The railway rail connection structure is described,

Publication No. 20-0322053 discloses a structure that separates the lower fixed base plate and the solder plate, interposes a pair of pads between them, and supports the rail fastening bolts on both sides of the base plate, and a reinforcing wall in front of the base plate. The rail dustproof fastening structure is known, which is composed of two elastic pads fitted to a support, a cushioning member, a cap on the cushioning member, and a stopper washer on the cap top surface.

Publication No. 20-0301026 discloses a cut portion in which a rail is cut diagonally in the longitudinal direction, and fills an insulating material between the cut portion and each rail and a joint plate coupled to the side, and fills the filled insulating material. The insulation structure of the rail for rails fixed to the rail and the joint plate is disclosed,

Conventional techniques as described above are complicated in structure, such as the need to cut and replace the rail during the repair of the welded rail, and when the train wheels pass through the gap between the rail of the train when the vibration and noise generated There has been a problem that can not expect quiet driving,

" 로서, 열차의 휠이 일시에 레일의 연결부를 통과시키는 종래의 레일형상을 변형시켜 열차의 휠이 순차적으로 레일의 연결부를 통과시켜 소음 및 진동을 감소시키고자 레일의 끝단부분을 본 발명에서 개량하였으며,The present invention is connected to a long bar-shaped rail perpendicular to the driving direction of the car is pulsating noise and vibration at a predetermined interval due to the friction generated when the wheel of the train passes through the connection portion of the rail at a time according to the running speed of the train Has been providing frequent failures and noise pollution due to vibration to trains and passengers. , With a Taegeuk rail or with a 45 ° intermediate part

In the present invention, the rails of the train are modified in the conventional rail shape in which the rails are temporarily passed through, so that the wheels of the trains are sequentially passed through the rails to reduce the noise and vibration. And

Conventionally, the connection structure of trains has simply been fixed by bolts and nuts by simply installing fittings or connecting members on the left and right sides of the rails, or by expanding the rails by heating them, and then welding them to secure the connections. There is a problem that needs to be dismantled,

In the present invention, the base plate is installed in the lower part to settle the rails, and after inserting and fixing the fitting member between the upper and the left and right sides of the base plate, the two fitting members and the rail are firmly fixed with bolts and nuts and connecting pins of the rail. It is a technical problem to be achieved by the present invention to provide a railway rail and a connection structure that is firmly fixed.

In order to achieve the above object, the present invention provides a rail 1 having both ends inclined at 45 °, a base plate 2 fixed to a lower part of the rail 1, and a base plate 2 of the present invention. A fixing screw 100 inserted into the fixing screw insertion hole 21 to fix the base plate 2, a fitting member 3 inserted into the left and right sides of the rail 1 and the base plate 2, and the two It relates to a connection structure of the railway rail consisting of a connecting bolt (4), a connecting nut (5) and a connecting pin (6) for connecting and fixing the two fitting member (3) and the rail through hole (11) of the rail (1) .

" 자로서, 열차의 주행방향에서 평면에서 보았을 때 막대형상의 직각방향이 아닌 45°로 경사진 형상의 레일이거나, 태극형상의 레일이거나, 중간부가 45°형상인 "

" 자로서, 열차의 휠이 일시에 레일의 연결부를 통과시키는 종래의 레일형상을 변형시켜 열차의 휠이 순차적으로 레일의 연결부를 통과시켜 소음 및 진동을 감소시키고자 레일의 끝단부분을 본 발명에서 개량하였으며,The rail used in the present invention is not a rectangular rail formed at right angles when viewed from a plane, but a rail inclined at 45 °, a taiji rail, or an intermediate part having a 45 ° shape.

"As a rule, the rail is inclined at 45 ° rather than at right angles in the direction of travel in the plane of the train, the rail is a Taegeuk shape, or the middle is 45 °."

"In the present invention, the wheel of the train deforms the conventional rail shape through which the rail is temporarily passed so that the wheel of the train sequentially passes through the rail connection to reduce noise and vibration. Improved,

Install the base plate on the lower part of the connection structure of the train, settle the rails, insert the fitting material between the upper part of the base plate and the left and right sides of the rail, and fix the two fitting materials and the rails with bolts, nuts and connecting pins. The rail is securely fixed.

In the above, the base plate, the fitting material is to be made of a material such as casting or iron plate to minimize the damage caused by the train driving.
