Traditionally, most of the side beams of the underframe have been of the channel type (U-type) or other I-type as described in Utility Model Publication No. 47-3368, and there have also been a few L-type beams in areas where there is no problem in terms of strength. A cross-sectional member is used. The purpose of these crossbeams is to support the main floorboards that support the loads on the floor and to take on the loads of the equipment below the floor. However, these horizontal beams are unsuitable for vehicles employing a double floor structure that requires high fire resistance and high sound insulation performance. That is,
It was necessary to separately provide a bracket for attaching the sub-floor board to the U-shaped or I-shaped horizontal beam.

近代車両の省エネルギ指向に反するものとなる。 These receivers (L-shaped members) are attached by welding or riveting, but this requires a large amount of man-hours to manufacture as it involves removing distortion due to welding heat, drilling holes for rivets, and caulking. In addition, the number of parts increases, which increases the number of parts management hours.Furthermore, since the receiver is attached separately, there are parts where parts are overlapped, resulting in an increase in weight.
This goes against the energy saving orientation of modern vehicles.

In the present invention, a plurality of cross beams are arranged between side beams arranged parallel to the longitudinal direction of the car body, at predetermined intervals in the longitudinal direction of the car body, and are arranged to extend in the width direction of the car body. In a vehicle underframe structure in which the ends are fixed to each of the side beams, the plurality of horizontal beams are shaped members having a continuous king-shaped cross section, and the central web of the shaped members has a longitudinal direction of the vehicle body. The width in the longitudinal direction of the lower web is made wider than the width in the longitudinal direction of the vehicle body,
A sub-floor board covering the lower surface of the heat and sound insulating material is disposed between the horizontal beams arranged adjacently, joined to the center web of each horizontal beam, and the dimension of the sub-floor board in the longitudinal direction of the vehicle body is as follows: It is characterized in that the distance is longer than the distance between the center webs of the adjacent horizontal beams and shorter than the distance between the lower webs of the adjacent horizontal beams.

Hereinafter, the present invention will be explained with reference to an illustrated embodiment. In the figure, 1 is the outer panel of the vehicle, 2 is the side pillar, and 4 is the outer panel of the vehicle.
is a long base, and these members are assembled as side blocks before the entire structure is assembled. 1
Reference numeral 2 denotes a horizontal beam, which is fitted into the channel groove of the side beam 3 and fixed to the side beam 3 by spot welding or the like to form an underframe block. The side structure blocks and the underframe blocks are connected by connecting the long base 4 and the side beams 3 by arc welding, spot welding, or the like.

材である。 The horizontal beam 12 has an upper web 5, a lower web 6, and a central web 7, and the upper web 5 supports the main floor plate 9. The lower web 6 is provided to balance the strength and rigidity of the cross beam 12 and to support underfloor equipment, and the central web 7 is provided to receive the sub-floor board 8. This sub-floor board 8 is vertically inserted into the mounting surface of the central web 7 based on the dimensional difference (B-A) between the central web 7 and the lower web 6, and is fixed with the mounting screws 11. 10 is a heat and sound insulation material packed between the main floor board 9 and the sub-floor board 8.

させることができる。 The present invention is constructed as described above, and the central web 7, which corresponds to the sub-floor plate support (previously, a separate angle material was attached by welding or riveting), is integrated into the horizontal beam 12. Therefore, there is no need to provide a separate sub-floor plate holder, and by providing a dimensional difference between the central web 7 and the lower web 6, the sub-floor plate 8 can be easily attached from below. Furthermore, the structure of the horizontal beam itself is simplified, the number of parts is reduced, and there are no parts where the members overlap, contributing to a reduction in manufacturing man-hours and weight. By the way, since the entire lower surface of the heat-insulating and sound-insulating material 10 is covered by the sub-floor board 8, rainwater or dust cannot enter and the heat-insulating and sound-insulating material 10 itself can be prevented from deteriorating. Ru. Moreover, if the sub-floor board 8 is made of metal, for example stainless steel, the fire resistance of the underframe itself can be improved.
