[0058] The plurality of support portions may include a first support portion 120, a second support portion 130, and a third support portion 140. The first support portion 120 may be formed by cutting a portion of a single metal plate and bending the cut region relative to the base 110. The first support portion 120 may be disposed approximately in the center of the base 110. The first support portion 120 may be disposed perpendicular to the base 110. The length from the upper surface of the base 110 to the upper end of the first support portion 120 may be longer than the length from the upper surface of the base 110 to the upper end of the second support portion 130 or the third support portion 140.

The first support portion 120 may be disposed on the inner circumferential surface of the first hole 181. The cross-sectional shape of the first hole 181 may be formed to correspond to the cross-sectional shape of the first support portion 120. For example, the cross-sectional shapes of the first hole 181 and the first support portion 120 may be approximately trapezoidal.

[0061] The first hole 181 may be disposed perpendicular to the first support portion 120. The first groove 127 may be formed in a region where one end of the first support portion 120 is connected to the inner surface of the first hole 181. A portion of the first groove 127 may be formed on one side of the first support portion 120, and the remaining portion may be formed on the lower surface of the base 110. In a region where the first groove 127 is formed and the first groove corresponds to a region connecting the first support portion 120 and the base 110, a rib 128 having an outwardly protruding shape may be formed. A portion of the rib 128 may be formed on the other side of the first support portion 120, and the remaining portion may be formed on the upper surface of the base 110. The strength of the connection region between the first support portion 120 and the base 110 may be enhanced by the rib 128.

[0063] The second support portion 130 may have a shape protruding upward from the edge of the base 110. The second support portion 130 may be coupled to a side of the second module 14. The side of the second module 14 coupled to the second support portion 130 may face the side of the second module 14 coupled to the first support portion 120.

[0064] The third support portion 140 may have a shape that protrudes upward from the edge of the base 110. The third support portion 140 may be coupled to a side of the second module 14. The side of the second module 14 that engages with the fourth support portion 140 may be adjacent to the side of the second module 14 that engages with the first support portion 120, or adjacent to the side of the second module 14 that engages with the second support portion 130.

A side of the first support portion 120 facing the first hole 181 may be opposite to a side of the first support portion 120 to which the support coupling portion 160 is coupled.

[0067] The support coupling portion 160 may be formed by cutting a portion of a metal plate. A second hole 183 that penetrates the lower surface from the upper surface may be formed in the base 110. The support coupling portion 160 may be located at one end of the inner circumferential surface of the second hole 183. The cross-sectional shape of the support coupling portion 160 may be formed to correspond to the cross-sectional shape of the second hole 183. The second hole 183 and the base 110 may be arranged perpendicular to the support coupling portion 160.

[0068] The support coupling portion 160 may be connected to the base 110 at one end, and the other end may be coupled to the side of the first support portion 120. The other end of the support coupling portion 160 may be joined to the side of the first support portion 120 by welding.

[0070] According to the above structure, the connection areas of the plurality of modules can be formed by a single metal plate, which has advantages in that the number of parts for forming the bracket is reduced, thereby reducing manufacturing costs, and improving production efficiency by omitting the joining process between the plurality of plates.

[0071] Figure 4 is a top view of a bracket according to a second embodiment of the present invention.

[0072] In this embodiment, except that the supporting coupling portion is provided in plurality, the other parts are the same as those in the first embodiment. Therefore, the same construction as the first embodiment uses the same reference numerals, and only the characteristic part of this embodiment is described below, and the rest is described using the first embodiment.

[0073] like Figure 4 As shown, this embodiment has a plurality of support couplings. In this case, the support coupling 160 of the first embodiment described above may be referred to as a first support coupling 160, and the other support couplings among the plurality of support couplings may be referred to as a second support coupling 170.

[0074] The second support coupling portion 170 may support one side surface of the first support portion 120. One side surface of the first support portion 120 can be supported by the first support coupling portion 160 and the second support coupling portion 170.

[0075] The second support coupling portion 170 may be formed by cutting a portion of a metal plate. A third hole 185 may be formed in the base 110, which runs through the lower surface shape from the upper surface. The second support coupling portion 170 may be disposed at one end of the inner circumferential surface of the third hole 185. The cross-sectional shape of the second support coupling portion 170 may be formed to correspond to the cross-sectional shape of the third hole 185. The third hole 185 and the base 110 may be disposed perpendicular to the second support coupling portion 170. The second support coupling portion 170 may be disposed to overlap with the first support coupling portion 160 in the horizontal direction. Based on the first support portion 120, the first support coupling portion 160 and the second support coupling portion 170 may be arranged symmetrically.

[0076] The second support coupling portion 170 may be connected to the base 110 at one end and coupled to the side of the first support portion 120 at the other end. The other end of the second support coupling portion 170 may be joined to the side of the first support portion 120 by welding.

[0077] The second support coupling portion 170 may include a first region 172 extending upward from the upper surface of the base 110, a second region 174 extending from the upper end of the first region 172 in a horizontal direction parallel to the base 110, and a third region 176 bent from an extended end of the second region 174 and coupled to a side surface of the first support portion 120. The first region 172 may be disposed perpendicular to the base 110, the second region 174, and the third region 176. The second region 174 may be disposed perpendicular to the third region 176. One side surface of the third region 176 may be welded to one side surface of the first support portion 120.

[0078] In this embodiment, a plurality of support coupling portions may be formed so as to support one side surface of the first support portion more firmly than the support coupling portions in the first embodiment.

[0080] In this embodiment, except that the support coupling portion extends from the first support portion, the other parts are the same as the first embodiment. Therefore, the same construction as the first embodiment uses the same reference numerals, and only the characteristic part of this embodiment is described below, and the rest is described using the first embodiment.

[0081] like Figure 5 and Figure 6As shown, in this embodiment, the bracket 300 may include a support coupling portion 310. In this case, unlike the first embodiment, the support coupling portion 310 may extend outward from the first support portion 120 rather than from the base 110. Therefore, since the support coupling portion 160 described in the first embodiment is formed (see Figure 2 ), so the second hole 183 may not be formed (see Figure 2 ).

[0082] In addition, the first holes 181a, 181b formed in the base 110 may also be formed so that the cross-sectional shape thereof corresponds to the sum of the cross-sectional shapes of the support coupling portion 310 and the first support portion 120. Therefore, the first holes 181a, 181b may include a 1-1 hole 181a corresponding to the cross-sectional shape of the first support portion 120 and a 1-2 hole 181a corresponding to the cross-sectional shape of the support coupling portion 310. The 1-1 hole 181a and the first support portion 120 may have a rectangular cross-sectional shape. The 1-1 hole 181a and the 1-2 hole 181b may be connected to each other.

[0083] The support coupling portion 310 may extend from one end of the edge of the first support portion 120, and the other end may be coupled to the upper surface of the base 110. The other end of the support coupling portion 310 may be coupled to the upper surface of the base 110 by welding.

[0084] The support coupling portion 310 may include a first region 312 extending from one side of the base 120, a second region 314 connected to the first region 312 at one end and extending downward, and a third region 316 bent from the other end of the second region 314 and coupled to the upper surface of the base 110. The second region 314 may be disposed perpendicular to the first region 312, the third region 316, and the base 110, and may be disposed parallel to the first support portion 120. The lower surface of the third region 316 may be welded to the upper surface of the base 110.

[0085] In this embodiment, one side of the first support portion 120 may be supported with respect to the base 110 by the support coupling portion 310 .
