The technical means of the present invention for achieving this object is as follows. First, claim 1
Is as follows. That is, the floor frame structure of this container is that of a container in which face plates are respectively assembled between frames that are orthogonal to each other in a vertical and horizontal direction, and are formed in a box shape and luggage is loaded inside. The floor frame has a substantially rectangular cylindrical shape in which an opening is formed in the center of the upper surface along the longitudinal direction and inner flanges are formed on the left and right sides of the upper surface through the opening. And a drain hole. Then, a side panel as a face plate is erected and fixed on one of the inner flange portions, and a floor interior material as a face plate is horizontally fixed on the other inner flange portion, and the side panel and the floor interior material are fixed. There are intervals between them. Next, claim 2 is as follows. That is, in this container floor frame structure, in the container floor frame structure of claim 1, the one inner flange portion on which the side panel is erected and fixed is the other inner flange portion on which the floor interior material is horizontally fixed. The height level is lower than the inner flange portion.

[0006]

The present invention is constituted by such means, and operates as follows. In this floor frame structure, an opening is formed in the center of the upper surface, inner flanges are formed on the left and right of the upper surface, drain holes are provided on the lower surface, and side panels are erected on the left and right inner flanges respectively. It is fixed and the floor interior material is fixed horizontally.

[0007] First, at the joint between the floor frame and the side panel, when used for a long period of time, the sealing is likely to be damaged, deteriorated, cracked, etc., and rainwater or the like is likely to infiltrate. The water is transmitted to the lower surface of the floor frame without being transmitted to the interior material side, and is discharged from the drain hole. In this way, the opening blocks the infiltration path of rainwater or the like, so that rainwater or the like is prevented from seeping into the floor interior material, and the inside luggage is prevented from getting wet. According to the second aspect, the inner flange portion is further stepped, and the inner flange portion to which the floor interior material is laterally fixed is located at an upper position, so that the above-mentioned point is more reliably realized.

Second, since the floor frame has a substantially rectangular tube shape with an inner flange portion integrally formed, the number of constituent members is reduced, and the number of constituent members is reduced by the formation of the opening. Raw materials are also reduced.

As the material 6, a lauan material or other wooden plate material, a veneer material or other plywood material, or another plate material is used.

In such a container, the structure of the floor frame 13 is as follows.
That is, as shown in the first embodiment of FIG. 1 and the second embodiment of FIG. 2, the floor frame 13 has an opening 16 opened in the center of the upper surface along the longitudinal direction. The inner flange portion 1 on the left and right sides of the upper surface through the opening 16
It is formed in a substantially rectangular tube shape in which the holes 7 and 18 are formed, and has a drain hole 19 on the lower surface. More specifically, the floor frame 13 is formed by sheet metal processing. The inner flange portions 17 and 18 are formed horizontally inward at the upper right and left ends of a long box-shaped main body having a substantially concave cross section, respectively. At the center of the upper surface between the inner flange portions 17 and 18
An opening 16 is formed as an interval between the two. A drain hole 19 is formed on the lower surface of such a lip groove type steel floor frame 13, and the drain hole 19 is
It has a slit shape, a plurality of round holes, and other forms.

A side panel 5 as a face plate is erected and fixed on one side, that is, on the outer inner flange portion 17, and the two side members 5 are attached to the interior member 11 having one end adhered to the side panel 5. , Are fixedly fastened by bolts 9 and nuts 10, and a sealing portion 7 is provided from the outside at a joint between the two. On the other side, that is, on the inner inner flange portion 18, the floor interior material 6 as a face plate is horizontally fixed and fixed by a screw 12, and a gap is closed between the two. Cover member 20 is provided. There is a predetermined space between the vertical side panel 5 fixed on the left and right inner flange portions 17 and 18 and the horizontal floor interior material 6 in this way. In the drawing, reference numeral 21 denotes an intermediate frame, and the intermediate frame 21 is disposed between two parallel floor frames 13 for reinforcement.

In the floor frame 13 of the first embodiment shown in FIG. 1, one inner flange portion 17 on which the side panel 5 is erected and fixed, and the other inner flange portion on which the floor interior material 6 is fixed horizontally. 18 are at the same height level. On the other hand, the floor frame 1 of the second embodiment shown in FIG.

That is, the inner inner flange portion 18 is located higher than the outer inner flange portion 17.

The present invention is configured as described above. Then, it becomes as follows. In the structure of the floor frame 13 of this container, an opening 16 is formed in the center of the upper surface along the longitudinal direction, inner flanges 17 and 18 are formed on the left and right of the upper surface, and a drain hole 19 is provided on the lower surface. A side panel 5 and a floor interior material 6 serving as face plates are fixed on the inner flange portions 17 and 18, respectively, in an upright position and a lateral position. Then, the following first and second cases are obtained.

First, in a joint portion between the floor frame 13 and the side panel 5, if used for a long period of time, the sealing 7 provided between them is liable to be damaged, deteriorated, cracked, etc., and rainwater or the like enters from outside. It's easy to do. However, according to the structure of the floor frame 13, the rainwater or the like that has entered from the joint portion of the floor frame 13 and the side panel 5 travels near the inner flange 17, the bolt 9, and the nut 10, and then has the opening 16. As a result, the water is transmitted downward to the lower surface of the floor frame 13 without being laterally transmitted to the floor interior material 6 serving as the interior interior material, and is discharged to the outside through the drain hole 19 on the lower surface. As described above, with respect to rainwater or the like that has entered from the joint portion of the floor frame 13 and the side panel 5, the penetration path transmitted to the floor interior material 6 is blocked by the opening 16, and the rainwater or the like seeps into the floor interior material 6. Is reliably prevented, and it is also possible to prevent the load A (see FIG. 4) loaded on the floor interior material 6 from getting wet. In other words, the penetration of rainwater and the like and the wetting of the baggage A as in the conventional example of this type shown in FIG.

In the three-structure, the inner flange portions 17 and 18 are further stepped, and the inner flange portion 18 to which the floor interior material 6 is fixed horizontally is fixed.
Are higher. Therefore, due to such a difference in the height level, the rainwater or the like that has entered as described above surely goes to the drain hole 19 on the lower surface of the floor frame 13.
The route of infiltration of rainwater or the like is more reliably blocked, so that the permeation of rainwater or the like into the floor interior material 6 is prevented, and the luggage A inside is avoided.

Secondly, such a floor frame 13 has a substantially rectangular cylindrical shape in which inner flange portions 17 and 18 are integrally formed on the main body, and this type of conventional example shown in FIG. The number of constituent members is reduced as compared with the case where two members, the plate 2 and the inner plate 3, are used. In addition, since the opening 16 is formed, the raw materials of the constituent members are reduced.

[0018]

As described above, the floor frame structure of the container according to the present invention has an opening along the longitudinal direction at the center of the upper surface and an inner flange at the left and right sides of the upper surface. According to the second aspect, the following effects are exhibited by further forming the inner flange portion to be stepped.

First, the waterproofness is improved. That is, it is possible to prevent rainwater or the like from seeping into the floor interior material, which is the interior interior material, and it is possible to reliably prevent the luggage loaded in the interior from getting wet, thereby improving the waterproof surface. In particular, in the second aspect, the waterproofness is further improved, for example, the permeation of rainwater or the like is prevented more reliably and the luggage is prevented from being wet.

Second, it is also excellent in cost.
That is, the number of constituent members and raw materials are reduced, so that costs for design, manufacture, mounting and the like are reduced. As described above, the effects exhibited by the present invention are remarkable and large, for example, the problems existing in this type of conventional example are eliminated.
