Description

Beam structure

The present invention relates to a box beam structure, and more specifically, the upper, lower, front, rear, left, and right side of the panel to form a beam structure of one box form to form a position where the exterior panel is formed in a curved surface The present invention relates to a box beam structure that can be installed in a portion and at the same time extend in length.

Conventionally, in order to make a box beam structure, a plurality of lateral stiffeners are welded to a longitudinal stiffener 130 (diagonal stiffener) at equal intervals as shown in FIGS. 1 and 2 to weld the internal reinforcement structure. After forming, the outer plate 140 was welded to form a box-shaped beam structure.

As described above, the longitudinal reinforcement member 130 is welded to the longitudinal reinforcement member 130 so that the longitudinal reinforcement member 120 is inserted into the longitudinal reinforcement member so that the longitudinal reinforcement member 130 is smoothly inserted into the longitudinal reinforcement member 130 and the horizontal reinforcement member after insertion. 120 was welded to form an internal reinforcement structure.

At this time, the lateral reinforcement 120 is divided into the L-shaped side longitudinal reinforcement (120a) and the I-shaped vertical longitudinal reinforcement (120b).

When the internal reinforcing structure is welded to the exterior, the intersection of the weld line of the reinforcement 130 and the welding line of the transverse reinforcement 120 is generated, and this portion is a portion where the structural stress concentration and the stress concentration according to the shape of the weld are welded. Fatigue damage occurs during use by the action of variable external force on the structure.

On the other hand, in order to increase the rigidity and strength of the box beam structure as described above, the number of longitudinal reinforcement 130 and the transverse reinforcement 120 must be increased inside the box beam, but the weld line crosses due to the increase of the reinforcement (120, 130). There is a problem that the number of parts increases, and thus the stress concentration increases, and thus the probability of fatigue damage increases, and the amount of steel used and the number of working hours increase.

In addition, in the case of the box beam structure manufactured as described above, when the shape of the outer wall or the inner wall forms a curved surface, there is a problem that the conventional box beam can not be installed according to the bending angle along the curved surface.

In order to solve the above problems, an improved box beam constituting the reinforcement in the vertical direction or up, down, left, and right directions outside the circular pie and combining the top, bottom, left and right flat panels with the reinforcement is provided. It is well shown in JP 2006-108482 A.

However, when a circular pipe, a reinforcement panel, and a flat panel are coupled to each other as described above, when the portion where the outer panel is installed is curved, there is a problem in that the installation itself is not possible.

The two conventional configurations are box beams applied in a vertical or horizontal state and cannot be installed at a curved position, which is designed by using 2D (2D computer graphics), which is mostly designed in 2D. Only when the simulation is applied to 3D (3D computer graphics) only to check and cut it as it is to produce the structure as described above there is a problem that can not be used as a box beam applied to the curved surface.

The present invention for solving the above problems is to facilitate the installation of the exterior panel to be installed on the curved surface and at the same time to configure the structure of the beam coupled to the external panel in the form of a rectangular box fatigue fracture phenomenon by the action of external force. It is an object of the present invention to provide a beam structure so that it can be prevented.
