  Therefore, in the case of the structure 1 of the present invention, when the structure 1 is stacked up and down, it is possible to achieve a reliable connection even at each corner portion, and a structure that can be disassembled, or the structure 1 When stacking as a container for transportation, the upper and lower connections are reliable, so multi-layer stacking is possible, and on land, it can respond to shaking of the ship due to waves, or shaking at the time of an earthquake. Depending on the situation, disassembly is possible.

  In carrying out the present invention, although not shown in the drawings, in order to reliably perform alignment with the fitting 1 in the upper structure 1 placed on the fitting 2 of the lower structure 1, On the upper horizontal plate 4 in the upper fitting 2, a positioning pin with a tapered guide portion that is tapered toward the upper end portion is vertically projected by screwing or the like, and the other structure positioned at the upper position. A pin hole may be provided in the lower horizontal plate of the fitting 2 below the object 1 so that the upper and lower structures 1 can be reliably positioned by at least one pair of pins and pin holes. It is good also as a form which makes a shear resistance function with respect to the horizontal force by a pin in addition to the friction joining by a high strength volt | bolt by said at least 1 set of pin and pin hole.

  When carrying out the present invention, a steel foundation may be used in addition to the concrete foundation 21. In this case, a female screw hole or a bolt insertion hole is provided in the steel foundation, and instead of the anchor bolt, a bolt or bolt- You may make it fix the structure 1 to a steel foundation using a nut.

  When carrying out the present invention, although not shown in the drawings, the connecting member 13 and the fitting 2 may have different heights. In this case, the lower or upper flange of the connecting member 13, the fitting 2, When a step in the vertical direction is generated between them, a spacer having a bolt insertion hole made of a steel plate or the like may be appropriately interposed and connected.

  When carrying out the present invention, when a structure such as a container for a ship, a container unit for a house, a container for a warehouse, a container for transporting an automobile or a freight car, a box-type structure, etc. In 1, facilities for various uses are arranged.

In the case of lifting and transporting the structure 1, the suspension frame body provided with a hanging bracket having a rotation locking bracket fixed to the vertical axis on the lower end side is suspended and supported by a crane or the like. The rotation locking bracket is inserted into the fitting 2 and the rotation locking bracket is rotated by 90 ° to engage the lower surface of the upper horizontal plate 4 so that it can be lifted and conveyed. .
