It is about to be done.

FIG. 11 is a side view showing a frame structure 112 according to a modification. In this modification, the inner edge 140c and the outer edge 140d of the side joint plate 140 of the corner member 118 are configured to have a corner cut shape instead of an arc shape. The inner edge 140c and the outer edge 140d of the side joint plate 140 are composed of a straight line extending in the z direction, a straight line extending in the x direction, and a straight line extending obliquely at 45 degrees to the x and z directions. The inner peripheral plate 142 is composed of a bent flat plate corresponding to the inner edge 140c. The outer cover 144 is composed of a bent flat plate corresponding to the outer edge 140d. According to this modification, the outer edge of the front opening 122 and the strip-shaped frame 124 can be configured to be octagonal, and the design of the exterior can be enhanced.

FIG. 12 is a side view showing a frame structure 212 according to another modification. In this modification, the width w1 of the girder 14 in the z direction and the width w2 of the column 216 in the x direction are not the same, and the width w2 of the column 216 is smaller than the width w1 of the girder 14 . The column 216 of this modified example includes an exterior plate 234 and a pair of core members 238a and 238b. The pair of core members 238a and 238b are arranged adjacent to each other in the x direction, for example, and no connection member is sandwiched between the pair of core members 238a and 238b. The connecting member 236 of the column 216 is composed of one end of the core member 238b of the pair, and the end of the one core member 238b is rigidly joined to the column joint plate 48 of the square member 218. As shown in FIG.

A width w3 from the inner edge 240c to the outer edge 240d of the corner member 218 changes depending on the position in the circumferential direction. The length of the first side 240 a of the side joint plate 240 is the same as the width w 1 of the girder 14 , and the length of the second side 240 b is the same as the width w 2 of the column 216 . Therefore, the length of the second side 240b is smaller than the length of the first side 240a. A width w3 from the inner edge 240c to the outer edge 240d of the corner member 218 gradually decreases from the girder 14 toward the column 216. As shown in FIG. In the example of FIG. 12, the inner edge 240c has an arc shape that is part of an ellipse, and the outer edge 240d has an arc shape that is part of a circle. Also in this modified example, the outer edge of the front opening 222 can be bordered by the rounded strip-shaped frame 224, so that the exterior design can be enhanced.

The container house 10 according to this embodiment may be used as a superstructure of a trailer house. For example, a connecting member may be attached to the floor structure composed of the lower girder 14a and the lower beam 20a of the container house 10 for connecting to tires for traveling and a towing part of a towing vehicle. For example, the tire and connecting member described in JP-A-2020-059321, which is incorporated herein by reference, can be applied to the container house 10 according to the present embodiment.
