본 발명은 도 1 및 도 3에 도시한 바와 같이 강 또는 알루미늄 압출형재 등으로 제조되고 사다리꼴 유사 단면으로 된 박스형 빔 본체(1)의 공동에 가로방향으로 리브(2)를 일체로 형성하고, 상기 빔 본체(1)의 후면(3) 양측에 범퍼 스테이(4)를 설치한 것에 있어서, 상기 빔 본체(1)의 중앙부 후면(3)에서 상·하면(13)(13')에 이르도록 일정 길이로 되고 빔 본체(1)와 동일재질로 된 단일 보강부재(14)를상·하면 (13)(13')에 리벳(15)으로 결합하여서 된 것이다.1 and 3, the ribs 2 are integrally formed in the cavity of the box-shaped beam body 1 made of steel or aluminum extrusion and having a trapezoid-like cross section, as shown in FIGS. In the case where the bumper stays 4 are provided on both sides of the rear surface 3 of the beam body 1, the beam body 1 is fixed so as to extend from the rear surface 3 of the central portion of the beam body 1 to the upper and lower surfaces 13 and 13 '. A single reinforcing member 14 having a length and made of the same material as the beam main body 1 is joined to the upper and lower surfaces 13 and 13 'by rivets 15.

상기한 보강부재(14)의 상·하면의 폭은 대략 빔 본체(1)의 상·하면(13) (13')의 중앙부까지 형성하면 좋고, 보강부재(14)를 빔 본체(1)에 결합할 때 리벳(15)을 도시하였으나 용접 또는 볼트에 의하여 결합할 수도 있는 것이다.The width of the upper and lower surfaces of the reinforcing member 14 may be formed up to the center of the upper and lower surfaces 13 and 13 'of the beam main body 1, and the reinforcing member 14 is attached to the beam main body 1. When the rivet 15 is shown to be coupled, it may be joined by welding or bolts.

이상과 같은 본 발명은 정면(화살표 방향)에서 충격이 가하여 지면 도 4의 가상선과 같이 빔 본체(1)가 변형하면서 충격을 흡수하며, 상기와 같이 충격을 흡수할 때 후면(3) 및 상·하면(13)(13')의 변형을 양호하게 억제하여 외부충격에 대한 지지력을 증대할 수 있는 것이다.In the present invention as described above, when the impact is applied from the front side (arrow direction), the beam main body 1 deforms as shown in the virtual line of FIG. 4, and the shock is absorbed. The deformation of the lower surfaces 13 and 13 'can be suppressed satisfactorily to increase the bearing capacity against external impact.

그리고 본 발명의 보강부재(14)의 상·하면의 결합 폭은 대략 빔 본체(1)의 상·하면(13)(13')의 중앙부 위치까지의 폭으로 하였음으로 경량화하면서 빔 본체 (1)의 상·하면(13)(13')의 변형을 최대로 억제할 수 있는 것이다.In addition, the width of the coupling between the upper and lower surfaces of the reinforcing member 14 of the present invention is approximately the width of the upper and lower surfaces 13 and 13 ′ of the beam main body 1, thereby reducing the weight. The deformation of the upper and lower surfaces 13 and 13 'can be suppressed to the maximum.

이상과 같이 본 발명은 빔 본체의 중앙부 후면에서 상·하면에 이르도록 단일 보강부재를 결합하였음으로 빔 본체가 충격을 흡수할 때 후면 및 상·하면의 변형을 양호하게 억제하여 외부충격에 대한 지지력을 증대시킴으로서 충격흡수성능을 증대할 수 있는 것이다.As described above, the present invention combines a single reinforcing member from the rear of the central part of the beam main body to the upper and lower surfaces so that the deformation of the rear and upper and lower surfaces is well suppressed when the beam main body absorbs the shock, thereby supporting the external impact. By increasing the shock absorption performance can be increased.
