DETAILED DESCRIPTION OF THE INVENTION

[0019] Hereinafter, an embodiment of the present disclosure will be described in detail with reference to the accompanying drawings.

[0020] In the accompanying drawings, the same or similar elements are denoted by the same reference numerals. In the drawings, the size or the thickness of each of the elements is exaggerated for ease of understanding. However, the scope of the present disclosure should not be interpreted as being limited thereto.

[0021] FIG. 1 is a view illustrating a configuration of a prefabricated shelf 100 to which a reinforcement beam for horizontal frames is applied, and FIG. 2 is a view illustrating a structure of vertical frames 102 that are illustrated in FIG. 1. As illustrated in the drawings, the prefabricated shelf 100 includes the vertical frames 102, the horizontal frames 104, and a support plate 106. The vertical frame 102 is formed of two support portions 202 and 204 that are connected perpendicularly to each other, and the support portions 202 and 204 are provided with a plurality of fastening holes 206.

[0022] The plurality of fastening holes 206 is provided in the support portions 202 and 204 at regular intervals such that an assembled height of the horizontal frames 104 is capable of being adjusted, and may be arranged in one row or multiple rows along in a longitudinal direction (or a Y direction) of the vertical frame 102. An upper hole 206a, a middle hole 206c, and a lower hole 206b are sequentially formed in each of the fastening holes 206 in the longitudinal direction. A width of the middle hole 206c is narrower than a width of the upper hole 206a, and the middle hole 206c is in communication with the upper hole 206a via a first inclined portion 206d. A width of the lower hole 206b is narrower than the width of the middle hole 206c, and the lower hole 206b is in communication with the middle hole 206c via a second inclined portion 206e.

[0023] Each of the vertical frames 102 is fitted with respective backing members 103 that are respectively provided with a receiving groove formed in an ‘L’ shape, and is provided vertically on each of the backing members 103, so that pillars of a shelf are formed. In addition, the vertical frames 102 are formed of a plurality of unit partial bodies having a predetermined length such that an overall height of the shelf can be changed. At this time, a bracket 108 is used in order to extend and connect at least two vertical frames 102.

[0024] FIG. 3 is a view illustrating a structure of the horizontal frame 104 that are illustrated in FIG. 1. As illustrated in the drawings, the horizontal frame 104 includes a connection portion 302, an abutment portion 304, and fastening protrusions 306a and 306b. FIG. 4 is a detailed view illustrating the fastening protrusions 306a and 306b that are illustrated in FIG. 3.

[0025] The abutment portion 304 is formed in a shape in which a corner of the connection portion 302 along a longitudinal direction (a Z direction) is folded approximately at a right angle by a predetermined width, and supports the support plate 106.

[0026] The connection portion 302 is provided with the fastening protrusions 306a and 306b that are formed in line on an outer surface of end portions of the connection portion 302. A distance between the fastening protrusions 306a and 306b is equal to a distance between the two fastening holes 206 that are formed in the vertical frames 102. The fastening protrusions 306a and 306b are protrudingly formed on the outer surface (or front surface) of both a first end and a second end of the connection portion 302. Between two vertical frames 102 that form the pillars, fastening protrusions 306a and 306b of both the first end and second end of the horizontal frame 104 are fastened to the fastening holes 206 at the same height. Since the fastening protrusions 306a and 306b are fastened to the fastening holes 206 from an inner sides of the vertical frames 102, the front surface of the horizontal frame 102 is in contact with rear surfaces of the vertical frames 102. Therefore, the size of protruding portions for fastening the horizontal frame 104 to the vertical frames 102 is minimized, so that an excellent aesthetic appearance of the shelf may be realized.

[0027] As illustrated FIG. 4, each of the fastening protrusions 306a and 306b is provided with a lower convex portion 402 and an upper convex portion 404 that are protruding in a thickness direction (an X direction) and that are having inclined surfaces inclined in a width direction (a Y direction), and is provided with wing portions 406 and 408 that protrude toward a longitudinal direction (a Z direction) from side surfaces of the upper convex portion 404. Between the lower convex portion 402 and the upper convex portion 404, a curved portion 403 having a discontinuous inclined surface is formed.

[0028] FIGS. 5A to 5C are views illustrating a configuration of a reinforcement beam 500 for horizontal frames, and FIG. 6 is a view illustrating a state in which the reinforcement beam 500 for the horizontal frames are mounted between the horizontal frames 104. As illustrated in the drawings, each of opposite end portions of a body portion 504 of the reinforcement beam 500 for the horizontal frames is provided with a pulling portion 502.

[0029] As illustrated in FIG. 6, the pulling portion 502 supports a lower outer surface 302a of the connection portion 302 of the horizontal frame 104, and prevents the lower portion of the connection portion 302 from being bent outward.

[0030] The body portion 504 is provided with a first horizontal member 506, a vertical member 508, and a second horizontal member 510. The first horizontal member 506, the vertical member 508, and the second horizontal member 510 are formed integrally with each other. A border between the first horizontal member 506 and the vertical member 508 and a border between the vertical member 508 and the second horizontal member 510 are folded approximately at a right angle by performing a bending, respectively. The first horizontal member 506 and the second horizontal member 510 are folded in the opposite direction to each other with respect to the vertical member 508. These orientations of the first and second horizontal frames 506 and 510 facilitate the fastening of the reinforcement beam 500 for the horizontal frames to the horizontal frames 104.

[0031] Opposite ends of the first horizontal member 506 in the longitudinal direction are folded approximately at a right angle toward the vertical member 508, so that the pulling portions 502 are formed. A first embossed reinforcement portion 503 is formed on each of the pulling portions 502.

[0032] Side surface support portions 509 formed on opposite ends of the vertical member 508 in a longitudinal direction support an inner side surface 302b of the connection portion 302. A gap capable of accommodating the connection portion 302 of the horizontal frame 104 is formed between the side surface support portion 509 and an internal side surface 502a of the pulling portion 502. The side surface support portion 509 of the vertical member 508 is formed such that a height thereof is lower than a height of the border between the vertical member 608 and the second horizontal member 510, so that a gap capable of accommodating the abutment portion 304 of the horizontal frame 104 is provided.

[0033] A locking portion 512 caught on the abutment portion 304 is formed on each of opposite ends of the second horizontal member 510 in a longitudinal direction. A second embossed reinforcement portion 513 is formed on each of the locking portions 512.

[0034] The locking portion 512 is formed in an inclined shape so that a length of a border portion 510a between the vertical member 508 and the second horizontal member 510 is shorter than a length of an opposite side end portion 510b. This shape of the locking portion 512 enables the reinforcement beam 500 to be easily mounted between the horizontal frames 104.

[0035] The embodiments described above are intended to facilitate the understanding of the present disclosure to those skilled in the art, and the scope of the present disclosure is not limited thereto. Therefore, it is obvious to those skilled in the art that various modifications and changes may be derived within the scope of the present disclosure.
