[0022] Preferred embodiments according to the present invention will be described in detail below with reference to the attached drawings. Prior to this, terms and words used in this specification and claims should not be interpreted as being limited to their ordinary or dictionary meanings, and should be interpreted in a meaning and concept consistent with the technical spirit of the present invention, based on the principle that the inventor can appropriately define the concept of the terms to best describe his invention.

[0023] Therefore, the embodiments described in this specification and the configurations illustrated in the drawings are merely the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention; thus, it should be understood that various equivalents and modifications that can replace them may exist at the time of filing this application.

[0024] The prefabricated frame system according to a preferred embodiment of the present invention illustrated in FIGS. 1 and 2 can be used for garbage collection stations, platforms, awnings, etc.

[0025] As illustrated in FIG. 3, the column-beam combined frame (100), which serves as a column or beam, has a square profile shape, and two sides arranged to face each other have U-shaped or inverted U-shaped grooves (110) formed along the longitudinal direction so that they are inwardly recessed. In this embodiment, the column-beam combined frame (100) is a rectangular profile shape formed such that the width (w1) of the side where the groove (110) is formed is greater than the width (w2) of the side where the groove (110) is not formed, as shown in FIG. 3.

[0026] A fastening line (111) is formed within the groove (110) so that a fastening means can be fastened, and the fastening line (111) can be used to position the fastening means when fastening a fastening means such as a direct fastening screw.

[0027] On both sides of the column-beam combined frame (100) where the groove (110) is not formed, either a positioning groove (130) or a positioning projection (230) is formed along the longitudinal direction. In this embodiment, two positioning grooves (130) are formed along the longitudinal direction on one side of the column-beam combined frame (100).

[0028] As illustrated in FIG. 4, the straight connecting member (200) is provided to be fixed to one side of the column beam / frame (100) and includes a straight plate (250) and a sliding connecting part (210).

[0029] The straight plate (250) is composed of a straight plate that is long in one direction. In order to easily position the fastening means (10), a fastening line (251) may be formed in the shape of a groove in the center of one side of the straight plate (250).

[0030] It is preferable that the sliding joint (210) includes a first vertical section (211) and a horizontal section (213). The first vertical section (211) extends vertically from one side of the straight plate (250). The horizontal section (213) extends in one direction from the first vertical section (211) so as to be horizontal with the straight plate (250). In this way, the sliding joint (210) forms an 'L' shape by including the first vertical section (211) and the horizontal section (213). To further increase the coupling strength of the sliding joint (210), it is preferable to further include a second vertical section (215) that extends vertically from the horizontal section (213) toward the straight plate (250). In this embodiment, two sliding joints (210) having the same shape are formed on one side of the straight plate (250). That is, two sliding joints (210) are formed protruding from one side of the straight plate (250) in the same direction.

[0031] On the other side of the straight plate (250), either a positioning groove (130) or a positioning projection (230) is formed along the longitudinal direction. In this embodiment, two positioning projections (230) are formed along the longitudinal direction on the other side of the straight connecting rod (200). Accordingly, the positioning projection (230) of the straight connecting rod (200) is seated in the positioning groove (130) of the column-beam combined frame (100), thereby making it easy to fix the position of the straight connecting rod (200) on one side of the column-beam combined frame (100).

[0032] As configured above, when the sliding joint (210) of a straight connecting member (200) fixed to one column-beam combined frame (100) as shown in FIG. 2 and the sliding joint (210) of a straight connecting member (200) fixed to another column-beam combined frame (100) are joined to each other in a sliding manner, the two column-beam combined frames (100) are joined to each other, thereby enabling expansion of the columns and beams in the left-right, front-back, and height directions.

[0033] As illustrated in FIG. 5, the vertical connecting member (300) is formed in the shape of an L or an inverted L. Additionally, one side of the vertical connecting member (300) is inserted into the inner side of one column-beam combined frame (100) so that the outer surface of one side of the vertical connecting member (300) can come into contact with the inner side of one column-beam combined frame (100), and the other side is inserted into the inner side of another column-beam combined frame (100) so that the outer surface of the other side of the vertical connecting member (300) can come into contact with the inner side of the other column-beam combined frame (100). That is, the cross-section of one side of the vertical connecting member (300) is formed to correspond to the cross-section of the column beam combined frame (100), and in this embodiment, the vertical connecting member (300) is in a rectangular shape, and two sides arranged to face each other have U-shaped or inverted U-shaped grooves (310) formed along the length direction so that they go inward.

[0034] As illustrated in FIG. 6, it is preferable that the frame connecting member (400) be inserted into the inner side of the column-beam combined frame (100) so that the outer surface of the frame connecting member (400) can come into contact with the inner surface of the column-beam combined frame (100). That is, the cross-section of the frame connecting member (400) is formed to correspond to the cross-section of the column-beam combined frame (100). In this embodiment, the frame connecting member (400) has a square profile shape, and U-shaped or inverted U-shaped grooves (410) are formed along the longitudinal direction so that the two sides arranged to face each other are inserted inward. A fastening means fastening part (430) is provided on the inner side of the frame connecting member (400), and in this embodiment, the fastening means fastening part (430) is provided on the inner side of the two sides arranged to face each other where the grooves (410) are not formed. The fastening means fastening part (430) has a circular cross-section and is open to one side. Furthermore, it is preferable that at least one reinforcing plate (450) be provided on the inner side of the frame connecting member (400) so that one side and the other side are connected to each other. In this embodiment, by connecting the grooves (410) on both sides with two reinforcing plates (450), the space inside the frame connecting member (400) is divided into three spaces by the two reinforcing plates (450).

[0035] As illustrated in FIGS. 1 and 2, first, looking at one support member (I), three column-beam combined frames (100) are each connected by four straight connecting members (200) and extended in the height direction indicated in the drawing to form a single beam (B1). FIG. 7 illustrates a structure in which the straight connecting members (200) of each column-beam combined frame (100) are slidably joined to one another. The end surface of one end of the beam (B1) is inclined so that it goes inward from top to bottom.

[0036] Three column-beam combined frames (100) are each connected by four straight connecting rods (200) and extended in the left-right direction indicated on the drawing to form a single column (P1-1), and one column-beam combined frame (100) is formed into another column (P1-2). A structure in which the straight connecting rods (200) of each column-beam combined frame (100) are slidably connected to each other is illustrated in FIG. 7.

[0037] One end of a column (P1-1) and a beam (B1) configured as described above are connected perpendicularly to each other using a vertical connecting member (300). When one side of the vertical connecting member (300) is inserted into the inner side of one column-beam combined frame (100) and the other side of the vertical connecting member (300) is inserted into the inner side of another column-beam combined frame (100), the two column-beam combined frames (100) are vertically connected, thereby vertically connecting the column (P1-1) to one side of the beam (B). At this time, the top surface of the column (P1-1) is sloped so that the height decreases from the outside to the inside, and the end surface of the beam (B) is sloped so that it goes inward from top to bottom, so that the column (P1-1) and the beam (B) are connected at an angle. For a secure connection, a fastening means (10) can be fastened to the part where a vertical connecting member (300) is inserted into the inner side of the column (P1-1) and the beam (B).

[0038] The other end of the other column (P1-2) and the beam (B1) configured as above is connected by a frame connecting member (400). The frame connecting member (400) is fixed to the other column (P1-2) by fastening the fastening means (10) to the fastening means fastening part (430) of the frame connecting member (400), and when the frame connecting member (400) is inserted into the other side of the beam (B1), the other end of the other column (P1-2) and the beam (B1) are connected so as to be perpendicular to each other.

[0039] Next, looking at the other support (II), one column-beam combined frame (100) is arranged as a beam (B2), and two column-beam combined frames (100) are arranged as two columns (P2). One end of one column (P2) and one end of the beam (B2) are connected perpendicularly to each other using a frame connecting member (400), and the other end of the other column (P2) and one end of the beam (B2) are connected perpendicularly to each other using a frame connecting member (400). Since the frame connecting member (400) has already been described in detail above, a detailed description will be omitted here.

[0040] A first finishing material (1100) as shown in FIG. 17 can be assembled on the top of the column (P1-2) and column (P2) using a single column-beam combined frame (100).

[0041] The first finishing material (1100) includes a first closing part (1110) and a column beam combined frame insert part (1120).

[0042] The first closing part (1110) is formed in the same way as the cross-section of the column-beam-frame to block the entire side of the column-beam-frame.

[0043] The column-beam combined frame insertion part (1120) protrudes from one side of the first closing part (1110) and is inserted into the column-beam combined frame (100). Accordingly, a step (1130) is formed between the first finishing material (1100) and the column-beam combined frame insertion part (1120).

[0044] As shown in FIG. 1, a roof plate (20) is placed on the upper part of two supports (I, II). In this embodiment, two roof plates (20) are provided, but the number of roof plates (20) may vary depending on the embodiment.
