GUARD RAIL FOR IMPACT ABSORPTION USING ROAD

摘要

The present invention prevents the vehicle from escaping out of the road by inadvertently absorbing the guardrail collision, and prevents the shock from being absorbed and prevents the passenger from the vehicle falling down the slope. The present invention relates to a guard rail for shock absorption of a road, having a U-shaped cross section, and having a fixing groove 11 formed at an upper end of the vertical portion, and having a bolt hole 12 penetrating the fixing groove 11 at a vertical portion. A foundation concrete 10 fixed to both sides of the road; The two lower movable plates 21 and the two upper movable plates 24 are inserted into the hinges 23 and the long bolts 32 are rotatably fixed to the lozenge, and a fixed plate ( 22 is fixed to the hinge 35, the fixing plate 25 is fixed to the upper end of the upper movable plate 24 by the hinge 26, bolts on the surface of the upper movable plate 24 and the lower movable plate 21 The fixing plate 28 is fixed to the fixing bolt 30, and a ring 31 is formed at the end of the fixing bolt 30 so that the spring 29 is fixed between the ring 31 facing each other, and the lower movable plate ( The fixing plate 22 of the 21 is inserted into the flange fixing groove 62 of the lower fixing stand 60 and fixed with bolts, and the fixing plate 25 of the upper moving plate 24 is connected to the fixing protrusion 72 of the fixing stand 70. Shock absorbing frame 20 is fixed to the bo The groove portion 43 is formed in the inside by being formed to have a V-shape with rubber, and fixed flanges 42 are formed at both ends, and the fixed flange 42 at the lower end is a flange fixing groove 62 of the lower fixing table 60. The fixed flange 42 is inserted into the flange, the top of the fixing flange 42 is inserted into the flange fixing groove 74 of the holder 70 is fixed by bolts, the two shock absorbing plate 40 is installed so as to face each other; The protrusion-like member 51 and the groove-like member 52 are formed to be symmetrical with each other in a shape similar to that of the groove 43 of the shock absorbing plate 40, and the protrusion-type member 51 has a protrusion at an end thereof. A 53 is formed, and the grooved member 52 has a groove portion 55 formed at an end thereof to fix the protrusion 53 and the groove portion 55 to be engaged with each other, and to form the protrusion member 51 and the grooved member 52. A bolt long hole 54 formed to penetrate both ends thereof, and a shock absorbing member 50 fixed to the shock absorbing frame 20 by a long bolt 32; A lower fixing member 60 having a protrusion 61 formed at a lower end thereof in a longitudinal direction and having two flange fixing grooves 62 formed at an upper end thereof; Two flange fixing grooves 74 are formed in the lower portion defined by the intermediate protrusion 73, the fixing member 70 is formed with a fixing groove 71 in the upper portion; A plurality of sound absorbing holes 81 are formed on the front and back of the case 84, and fixing protrusions 83 are formed at the lower end thereof, and sound absorbing material 82 is inserted and fixed therein to be fixed to the upper end of the fixing table 70. It is characterized by consisting of; a sound absorbing plate (80).;Guard rail, shock absorbing frame, sound absorbing plate, shock absorbing member
