The upper member 110 is formed to be bent from both sides of the first member 112 and the longitudinal direction of the first member 112 covering the upper surface of the abdominal member 100, and the second member covering the longitudinal side surface of the abdominal member 100. Member 114. The height of the second member 114 is formed longer than the height of the abdominal member 100.

The upper member 110 further includes a bottom member 116 that is bent from the second member 114 and extends in a direction covering the lower surface of the abdominal member 100. The bottom member 116 is integrally formed with the upper member 110. The bottom member 116 is formed to be shorter than the widthwise length of the first member 112 to be in contact with the abdominal members 100 disposed on both sides of the abdominal member 100 among the plurality of abdominal members 100, respectively. . The bottom member 116 is formed shorter than the widthwise length of the abdominal member 100.

The upper member 110 further includes a side member 118 covering the widthwise side surface of the abdominal member 100 at both widthwise sides of the first member 112. The side member 118 may be welded to the upper member 110.

A lifting hole 113 may be formed at the corner side of the upper surface of the upper material 110. The lifting hole 113 is used to mount the lifting device during transportation, construction and dismantling of the perforated plate.

The bent bottom surface and the bottom member of the abdominal member 100 are welded together. That is, the stopper member 130 constituting the lower member is coupled to the bottom member 116 and the abdominal member 100 by welding. The bent upper surface and the upper member 110 of the abdominal member 100 may also be welded. The bent upper surface of the upper member 100 and the upper side of the upper member 110 may be coupled by spot welding, and the side surfaces of the upper member 110 and the upper member 110 may be coupled by line welding.

Meanwhile, the stopper member 130 constituting the lower member may be fastened with the bottom member 116 and the abdominal member 100 by screws, and the stopper member 130, the bottom member 116, and the abdominal member 100 may be screwed. Holes 131, 117, and 101 may be formed in the fastening sites, respectively.

In the case of using the shaped steel product to form the upper surface of the perforated plate, the welding joining method is used to join the shaped steels. In this case, due to the degradation of the quality of the welded portion formed along the longitudinal direction of the section steel, durability problems such as welding drop off due to the driving of the vehicle are generated, resulting in reduced vehicle runability and noise.

In addition, the perforated plate combining the ready-made steel products is not optimized in cross section, the steel weight of the perforated plate is increased, there is a problem such as an increase in production cost, transportation cost, deterioration of workability.
