  Most of the plurality of horizontal beams 30 shown in FIG. 2 extend in the width direction of the track 1 through the vertical portions 13 (FIG. 3) of the vertical beams 10 and the vertical portions (not shown) of the vertical beams 20. ing. However, some of the plurality of horizontal beams 30 shown in FIG. 2 do not pass through the vertical beams 10 and 20. A part of the horizontal girder 30 that does not penetrate the stringers 10 and 20 is abutted against the vertical portion 13 (FIG. 3) of the column girder 10 and the vertical portion (not shown) of the column girder 20 and welded to these vertical portions. It is fixed by other methods.

  FIG. 3 is referred to again. Each floor plate 40 is arranged in parallel with each other along the longitudinal direction of the cross beam 30, and extends along the longitudinal direction of the vertical beam 10 and the vertical beam 20 (FIG. 2). In other words, each floor board 40 is parallel to the two vertical beams 10 and 20 shown in FIG. 2 and straddles a plurality of horizontal beams 30. As shown in FIG. 3, the upper surfaces 41 of the respective floor boards 40 are substantially flush with each other. Further, the upper surface 41 of the floor plate 40 and the upper surface 11a of the upper horizontal portion 11 of the vertical girder 10 are substantially flush with each other, but the upper surface 11a of the upper horizontal portion 11 of the vertical girder 10 is slightly smaller than the upper surface 41 of the floor plate 40. Low.

  As shown in FIG. 3, the stringer 10 is provided with a water stop cover 50 over its entire length. The water stop cover 50 is a pressed sheet metal, and as shown in FIG. 4, a pair of opposed vertical plate portions 51 and 52, and a horizontal plate portion 53 connecting the vertical plate portions 51 and 52 to each other. , Has a central portion 54 shaped into a U-shaped cross section. A pair of flange portions 55 and 56 are connected to both sides in the width direction of the central portion 54 over the entire length thereof. Each of the vertical plate portions 51 and 52 is bent substantially at right angles to the horizontal plate portion 53. The flange portion 55 is bent at a substantially right angle with respect to the vertical plate portion 51, and the flange portion 56 is bent at a substantially right angle with respect to the vertical plate portion 52. On the other hand, the flange portions 55 and 56 are substantially parallel to the horizontal plate portion 53. Further, a concave portion 57 is formed on the upper surface of each of the flange portions 55 and 56 over the entire length thereof.

  As shown in FIGS. 3 and 4, the water stop cover 50 is put on the stringer 10 like a hat, and straddles the stringer 10 and the floor plate 40 on both sides thereof. Specifically, as shown in FIG. 3, the central portion 54 of the water stop cover 50 is covered on the vertical girder 10 so as to cover the upper horizontal portion 11 of the vertical girder 10. More specifically, the horizontal plate portion 53 of the central portion 54 covers the upper surface 11a of the upper horizontal portion 11 of the vertical girder 10, and the vertical plate portions 51 and 52 of the central portion 54 11 is interposed between each side surface 11b and each side surface 42 of the floor plate 40 on both sides of the stringer 10. Further, the flange portions 55 and 56 of the water stop cover 50 are interposed between the upper surface 31 a of the upper horizontal portion 31 of the cross beam 30 and the lower surface 43 of the floor plate 40. Although not shown, the same water-stop cover as the water-stop cover 50 shown in FIGS. 3 and 4 is similarly provided on the vertical girder 20 shown in FIG.

  As shown in FIG. 3, an under pan 60 is provided below the floor plate 40. In the present embodiment, three underpans 60 are provided, one of which is provided in an area between the two stringers 10 and 20 shown in FIG. , And the other sheet is provided in an area outside the stringer 20. Each of the underpans 60 has substantially the same overall length as the vertical girders 10 and 20 and straddles a plurality of horizontal girders 30. In short, the underpan 60 is arranged below the floor plate 40 shown in FIG. 3 so as to cover substantially the entire floor surface.

  As shown in FIG. 3, the end of the underpan 60 overlaps the flange portions 55 and 56 of the water stop cover 50. In other words, the end of the underpan 60 is sandwiched between the upper surfaces of the flange portions 55 and 56 and the lower surface 43 of the floor plate 40 facing the upper surfaces. Further, between the flange portions 55 and 56 and the end of the under pan 60, a sealing material 58 filled in the concave portion 57 (FIG. 4) of the flange portions 55 and 56 is interposed. The underpan 60 in the present embodiment is a galvanized steel plate, and the sealing material 58 is butyl rubber. However, the underpan 60 can be replaced with, for example, an aluminum plate or a FRP (Fiber-Reinforced Plastics) plate. Further, the sealing material 58 is not limited to butyl rubber.

  As shown in FIG. 3, a spacer 61 is arranged between the underpan 60 and the floor plate 40. A double-sided tape is provided on the back surface of the spacer 61 (the surface facing the underpan 60), and the spacer 61 is attached to the underpan 60 with the double-sided tape. However, the spacer 61 is not provided on the entire surface of the underpan 60, but is provided only at a position corresponding to the upper horizontal portion 31 of the cross beam 30.

  As shown in FIG. 3, the upper surface 54 a of the central portion 54 of the water stop cover 50 is substantially flush with the upper surface 41 of the floor plate 40 on both sides of the vertical girder 10 on which the water stop cover 50 is covered. As described above, the upper surface 11 a of the upper horizontal portion 11 of the stringer 10 is slightly lower than the upper surface 41 of the floor plate 40. However, since the central portion 54 of the waterproof block 50 is placed over the upper horizontal portion 11 of the girder 10, the height difference between the upper surface 11 a of the upper horizontal portion 11 of the girder 10 and the upper surface 41 of the floor plate 40 is compensated. Therefore, a flat floor surface is formed as a whole. In other words, when the central portion 54 of the water stop cover 50 is placed on the upper horizontal portion 11 of the girder 10, the respective portions are so arranged that the upper surface 54 a of the central portion 54 and the upper surface 41 of the floor plate 40 are substantially flush. Is set in advance, and the spacer 61 is inserted.

  As described above, in the floor structure according to the present embodiment, the stringer 10 is covered with the waterproof block 50 that straddles the stringer 10 and the floor plate 40 on both sides of the stringer 10. Further, the water stop cover 50 is interposed between the horizontal plate portion 53 that covers the upper surface 11 a of the upper horizontal portion 11 of the vertical girder 10, and the side surface 11 b of the upper horizontal portion 11 of the vertical girder 10 and the side surface 42 of the floor plate 40. It has vertical plate parts 51 and 52 and flange parts 55 and 56 interposed between the upper surface 31 a of the upper horizontal part 31 of the horizontal girder 30 and the lower surface 43 of the floor plate 40. In addition, each of the horizontal plate portion 53, the vertical plate portions 51, 52, and the flange portions 55, 56 of the water stop cover 50 is a part of one bent sheet metal. In other words, the vertical plate portions 51 and 52 are connected to the horizontal plate portion 53, and the flange portions 55 and 56 are connected to the horizontal plate portion 53 via the vertical plate portions 51 and 52. Therefore, as shown in FIG. 3, water infiltrates into the cargo room from between the stringer 10 and the floor plate 40, particularly, between the side surface 11 b of the upper horizontal portion 11 of the stringer 10 and the side surface 42 of the floor plate 40. Nothing.

  The above structure is the same for the vertical beam 20 shown in FIG. 2 and the floor plate 40 on both sides thereof. Therefore, water does not enter the cargo room from between the stringer 20 and the floor plate 40, particularly, between the side surface of the upper horizontal portion of the stringer 20 and the side surface of the floor plate 40.

  The present invention is not limited to the above embodiment, and can be variously modified without departing from the gist thereof. For example, a cushioning material may be arranged between the stringer and the water stop cover. In this case, it is preferable to arrange a tape-shaped cushioning material between the upper surface 11a of the upper horizontal portion 11 of the vertical girder 10 and the lower surface of the horizontal plate portion 53 of the water stop cover 50 shown in FIG. The present invention can be applied not only to trucks other than van-type trucks but also to floor structures of luggage compartments of trucks other than trucks.
