If the 1-angle material 3 is not removed, the second and third angle materials 5 and 7 cannot be removed. In other words, in the state where the end portions of the first, second, and third angle members 3, 5, and 7 are combined, the first angle member 3 can be held and lifted up as a whole.

  By the way, in order to prevent the first angle member 3 from coming off in the direction opposite to the arrow A after combining the end portions of the first, second, and third angle members 3, 5, and 7, Spot welding is performed on a part of the joint between the angle member 3 and the second and third angle members 5 and 7, or the first angle member 3 is attached to the second angle member 2 by an appropriate fixing tool such as a set screw or a hook. What is necessary is just to fix to at least one of the 3rd angle materials 5 and 7. FIG. In this case, it is sufficient to fix the first angle member 3 so that it does not come off from the second and third angle members 5 and 7, and therefore it can be implemented with a simple configuration.

  By the way, the configuration of both end portions of the reinforcing angle members 9, 11, 15 in the frame structure 1 is as shown in FIG. That is, both end portions of the angle member 9 are provided with inner angle engagement portions 25 that engage with inner angle portions of the first and second sides 5A and 5B of the second angle member 5, and the inner angle engagement. In order to form the portion 25, a cutout portion 27 in which one side is deleted is formed. An engagement protrusion 29 is provided at the distal end of the inner angle engagement portion 25 and is fitted into an engagement hole 5H (see FIG. 1) formed in the second and third angle members 5. The protrusion amount of the engagement protrusion 29 is a protrusion amount substantially equal to the thickness of the second angle member 5. Note that the engagement protrusion 29 in the reinforcing angle member 11 is inserted into the engagement hole 7 </ b> H formed in the third angle member 7.

  As shown in FIG. 5, one end of the auxiliary angle member 13 has the same configuration as the end portions of the angle members 9 and 11, so that components having the same function are denoted by the same reference numerals and are duplicated. Description is omitted. The other end of the auxiliary angle member 13 between the second angle member 5 and the angle member 11 that contacts the angle member 11 is formed as a contact surface that contacts the angle member 11. Is formed with an engagement protrusion 31 that is inserted into an engagement hole (not shown) provided in the angle member 11. The protrusion amount of the engagement protrusion 31 is set to a protrusion amount that is approximately ½ of the thickness of the angle member 11 so that the engagement protrusion 31 of the other angle member 13 is not pressed against. is there.

  With the above configuration, each of the angle members 9, 11, 13, 15 can be combined with the frame structure 1 as shown in FIG. The auxiliary angle members 9, 11, 13, and 15 can be omitted.

  As can be understood from the above description, according to the present embodiment, it is easy to combine the end portions of each angle member without using an assembly jig or the like, for example. In addition, after combining the ends of a plurality of angle members in a state intersecting in three directions, it becomes difficult to remove each angle member due to the engagement between the engagement recesses and the engagement protrusions provided at the ends. Thus, the angle members can be easily fixed to each other.
