Background Technology

[0003] In general, it is common practice to use prefabricated construction methods when building large buildings. This construction method proceeds by first constructing the building's frame, and then pouring slabs and retaining walls simultaneously for each floor. Recently, metal panels have been widely used for roofing buildings constructed in this manner.

[0004] However, when constructing a roof with such metal panels, there was a problem where melted snow or rainwater could easily penetrate through the joints due to the simple assembly structure between adjacent metal panels.

[0005] Water that penetrates into the assembly area in this way flows along the metal panels, corroding metal materials such as bolts used in construction, and eventually causes leakage problems.

[0006] Therefore, there is a need for a method to prevent leakage by draining melted snow or rainwater to the outside at the initial stage of penetration, even if such water penetrates the assembly area. The problem to be solved

[0034] FIG. 1 is a schematic diagram for explaining a roof panel assembly according to an embodiment of the present invention, FIG. 2 is a perspective view showing a prefabricated steel plate of a roof panel assembly according to an embodiment of the present invention, FIG. 3 and FIG. 4 are schematic diagrams for explaining a first assembly part provided on a prefabricated steel plate of a roof panel assembly according to an embodiment of the present invention, FIG. 5 and FIG. 6 are schematic diagrams for explaining a second assembly part provided on a prefabricated steel plate of a roof panel assembly according to an embodiment of the present invention, FIG. 7 is a schematic diagram for explaining a joining structure of adjacent prefabricated steel plates in a roof panel assembly according to an embodiment of the present invention, and FIG. 8 is a schematic diagram showing a fastening member of a roof panel assembly according to an embodiment of the present invention.

[0036] As illustrated in FIG. 1, a roof panel assembly (100) according to one embodiment of the present invention may be a panel that is overlaid on an exterior panel (10), such as a single steel plate or a sandwich panel. Meanwhile, the roof panel assembly (100) may be a panel that is overlaid on an exterior panel (10), such as an aged single steel plate or a sandwich panel, or it may be a new roof panel assembly that is not intended for overlay.

[0037] A roof panel assembly (100) according to one embodiment of the present invention may be formed by including a prefabricated steel plate (110) and a fastening member (120).

[0039] The above prefabricated steel plate (110) can be assembled in one direction with an adjacent prefabricated steel plate (110') in the longitudinal direction.

[0040] Accordingly, prefabricated steel plates (110, 110') adjacent to each other in the longitudinal direction can be continuously assembled in one direction, thereby allowing for expansion to a desired area.

[0041] At this time, adjacent prefabricated steel plates (110, 110') are distinguished only for convenience of explanation, and may be made of the same material and have the same structure.

[0042] According to one embodiment of the present invention, prefabricated steel plates (110, 110') adjacent to each other in the longitudinal direction can be assembled together through a simple snap-fit ​​method.

[0043] Accordingly, melted snow or rainwater can easily penetrate into the assembly area between adjacent prefabricated steel plates (110, 110') in the longitudinal direction, corroding the metal and causing leakage.

[0044] Accordingly, a roof panel assembly (100) according to one embodiment of the present invention solves the problem of leakage through a double waterproof structure, which will be explained in more detail below.

[0045] According to one embodiment of the present invention, the prefabricated steel plate (110) is provided in a plate shape and can be extended in one direction.

[0046] These prefabricated steel plates (110) can be overlaid on exterior panels (10), such as single steel plates or sandwich panels. Meanwhile, the prefabricated steel plates (110) can be installed on a new roof that is not intended for overlaying. In this case, the prefabricated steel plates (110) may refer to the top steel plates of a new single steel plate or a new sandwich panel.

[0047] According to one embodiment of the present invention, the prefabricated steel plate (110) may include a body portion (111), a first assembly portion (112), and a second assembly portion (113).

[0048] Referring to FIG. 2, the body portion (111) can be defined as an area extending in one direction between the first assembly portion (112) and the second assembly portion (113) in the prefabricated steel plate (110).

[0049] Given that the first assembly part (112) and the second assembly part (113) are end structures of the assembly steel plate (110) for assembly, the size and length of the assembly steel plate (110) can be substantially defined by the body part (111).

[0050] The above body portion (111) can be in close contact with the upper surface of the exterior panel (10). At this time, if the exterior panel (10) has an uneven structure in the longitudinal direction, the body portion (111) may also have a corresponding uneven structure to match it.

[0051] The first assembly part (112) may be provided at one end in the longitudinal direction of the prefabricated steel plate (110), more specifically, the body part (111). The first assembly part (112) may protrude upward relative to the body part (111). At this time, a groove corresponding to the protruding shape may be formed on the lower side of the first assembly part (112) protruding upward relative to the body part (111).

[0052] According to one embodiment of the present invention, when a prefabricated steel plate (110) is overlaid on an exterior panel (10), the first assembly part (112) may face the second assembly part (113') of the prefabricated steel plate (110') that is overlaid on the exterior panel (10) in an up-and-down direction.

[0053] At this time, a space may be provided between the first assembly part (112) and the second assembly part (113') of an adjacent assembly steel plate (110') facing it in the vertical direction to accommodate the head part (121 in FIG. 8) of a fastening member (120) that is fastened to fix the assembly steel plate (110) to the exterior panel (10).

[0054] The first assembly part (112) can be combined with the second assembly part (113') of an adjacent prefabricated steel plate (110') in a manner that is covered by the second assembly part (113') of an adjacent prefabricated steel plate (110'). At this time, the second assembly part (113') of the adjacent prefabricated steel plate (110') can be fitted into the first assembly part (112).

[0055] Through this, the roof panel assembly (100) according to one embodiment of the present invention can be extended in one direction.

[0056] Referring to FIGS. 3 and 4, the first assembly part (112) may include a first-1 vertical part (112a), a first-1 inclined part (112b), a first-2 inclined part (112c), a drainage channel (112d), a fastening part (112e), a first-3 inclined part (112f), a first-4 inclined part (112g), a first-5 inclined part (112h), a first-2 vertical part (112i), a first horizontal part (112j), and a first-3 vertical part (112k).

[0057] The first-1 vertical section (112a) may be provided at one end in the longitudinal direction of the body section (111). The first-1 vertical section (112a) may extend from one end in the longitudinal direction of the body section (111).

[0058] This first-1 vertical section (112a) may be provided in a plate shape. The first-1 vertical section (112a) may be bent from the body section (111). At this time, the first-1 vertical section (112a) may be bent vertically upward relative to the body section (111).

[0059] The first-1 inclined portion (112b) may be provided at the upper end of the first-1 vertical portion (112a) in the longitudinal direction. The first-1 inclined portion (112b) may extend from the upper end of the first-1 vertical portion (112a) in the longitudinal direction.

[0060] This first-1 inclined portion (112b) may be provided in a plate shape. The first-1 inclined portion (112b) may be bent from the first-1 vertical portion (112a). At this time, the first-1 inclined portion (112b) may be bent upwardly inclined toward the outside of the body portion (111).

[0061] According to one embodiment of the present invention, the first-1 inclined portion (112b) may have a first slope. When adjacent prefabricated steel plates (110, 110') are assembled, the second-6 inclined portion (113j in FIG. 6) of the adjacent prefabricated steel plate (110') may be in close contact with the first-1 inclined portion (112b).

[0062] At this time, the second-6 slope (113j in FIG. 6) may have a second slope greater than the first slope.

[0063] Accordingly, the 2-6 inclined section (113j in FIG. 6) is pressed against the 1-1 inclined section (112b), thereby forming a primary waterproof structure, which will be explained in more detail below.

[0064] The first-2 inclined section (112c) may be provided at the upper end of the first-1 inclined section (112b) in the longitudinal direction. The first-2 inclined section (112c) may extend from the upper end of the first-1 inclined section (112b) in the longitudinal direction.

[0065] These first-2 inclined sections (112c) may be provided in a plate shape. The first-2 inclined section (112c) may be bent from the first-1 inclined section (112b). At this time, the first-2 inclined section (112c) may be bent upwardly inclined toward the inside of the body section (111).

[0066] The above drainage channel (112d) may be provided at the upper longitudinal end of the first-second slope (112c). The above drainage channel (112d) may extend from the upper longitudinal end of the first-second slope (112c).

[0067] Here, when adjacent prefabricated steel plates (110, 110') are assembled, melted snow or rainwater flows along the body part (111) and can penetrate into the assembly area between adjacent prefabricated steel plates (110, 110').

[0068] In this way, the water penetrating into the assembly area between adjacent prefabricated steel plates (110, 110') can flow into the drainage channel (112d) by passing through the first-1 vertical section (112a), the first-1 inclined section (112b), and the first-2 inclined section (112c) in sequence.

[0069] According to one embodiment of the present invention, such a drainage channel (112d) can provide a path for the infiltration water to be discharged to the outside before reaching the fastening part (112e), so that the inflow of infiltration water that travels along the prefabricated steel plate (110) into the fastening part (112e) which provides the fastening surface of the fastening member (120) is blocked.

[0070] To this end, the drainage channel (112d) may be provided on the upstream side of the connection part (112e) based on the expected path of infiltration of the infiltrating water.

[0071] According to one embodiment of the present invention, the drainage channel (112d) may be provided at one end in the longitudinal direction of the fastening portion (112e). The drainage channel (112d) may be provided between the first-second inclined portion (112c) and the fastening portion (112e).

[0072] This drainage channel (112d) is provided in the shape of a 'U' groove and can be extended in a first direction away from the expected path of infiltration of the infiltrating water at a position lower than the connecting part (112e). Through this, the drainage channel (112d) can induce drainage of the infiltrating water in the first direction.

[0073] For example, the first direction may be a direction perpendicular to the direction in which the prefabricated steel plate (110) extends with respect to the plane.

[0074] In this way, the seepage water drained in the first direction by the drainage channel (112d) can be discharged along the roof slope into the gutter at the bottom.

[0075] Accordingly, according to one embodiment of the present invention, even if melted snow or rainwater penetrates into the assembly area between adjacent prefabricated steel plates (110, 110'), the penetrating water can be smoothly discharged to the outside in the early stages of penetration.

[0076] That is, according to one embodiment of the present invention, even if water such as melted snow or rainwater penetrates into the assembly area between adjacent prefabricated steel plates (110, 110'), the water can be discharged to the outside before reaching the assembly area connected by a metal fastening member (120), thereby preventing corrosion of the fastening member (120) and preventing leakage.

[0077] The above-mentioned fastening portion (112e) may be provided at the top of the drainage channel (112d). The above-mentioned fastening portion (112e) may extend from the top of the drainage channel (112d).

[0078] The above fastening portion (112e) may be provided in a plate shape. The above fastening portion (112e) may be bent from the drainage channel (112d). At this time, the above fastening portion (112e) may be horizontally bent to the outside of the body portion (111).

[0079] According to one embodiment of the present invention, the fastening portion (112e) may provide a fastening surface of a fastening member (120) that is fastened to fix the prefabricated steel plate (110) to the exterior panel (10).

[0080] As described above, based on the expected path of infiltration water, a drainage channel (112d) is provided on the upstream side of the connection part (112e), thereby blocking the inflow of infiltration water into the connection part (112e).

[0081] Accordingly, corrosion of the fastening member (120) made of metal material due to water penetrating into the assembly area between adjacent prefabricated steel plates (110, 110') can be prevented.

[0082] The first-third inclined portion (112f) may be provided at the other end in the longitudinal direction of the fastening portion (112e). The first-third inclined portion (112f) may extend from the other end in the longitudinal direction of the fastening portion (112e).

[0083] These first-third inclined portions (112f) may be provided in a plate shape. The first-third inclined portions (112f) may be bent from the fastening portion (112e). At this time, the first-third inclined portions (112f) may be bent downwardly inclined toward the outside of the body portion (111).

[0084] The first-fourth inclined section (112g) may be provided at the longitudinal lower end of the first-third inclined section (112f). The first-fourth inclined section (112g) may extend from the longitudinal lower end of the first-third inclined section (112f).

[0085] These first-fourth inclined portions (112g) may be provided in a plate shape. The first-fourth inclined portion (112g) may be bent from the first-third inclined portion (112f).

[0086] At this time, the first-fourth inclined portion (112g) can be bent downwardly inclined toward the inside of the body portion (111).

[0087] The above-mentioned first-fifth inclined section (112h) may be provided at the longitudinal lower end of the first-fourth inclined section (112g). The above-mentioned first-fifth inclined section (112h) may extend from the longitudinal lower end of the first-fourth inclined section (112g).

[0088] These first-fifth inclined sections (112h) can be bent from the first-fourth inclined section (112g). At this time, the first-fifth inclined section (112h) can be bent downwardly inclined toward the outside of the body section (111).

[0089] According to one embodiment of the present invention, the first-5 slope section (112h) may have the same first slope as the first-1 slope section (112b). That is, the first-5 slope section (112h) and the first-1 slope section (112b) may be symmetrical (based on the drawing).

[0090] The first-2 vertical section (112i) may be provided at the longitudinal lower end of the first-5 inclined section (112h). The first-2 vertical section (112i) may extend from the longitudinal lower end of the first-5 inclined section (112h).

[0091] At this time, the first-2 vertical section (112i) can be extended to a length corresponding to the first-1 vertical section (112a).

[0092] These first-2 vertical sections (112i) may be provided in a plate shape. The first-2 vertical sections (112i) may be bent from the first-5 inclined sections (112h).

[0093] At this time, the first-2 vertical section (112i) can be vertically bent downward from the first-5 inclined section (112h).

[0094] The first horizontal section (112j) may be provided at the lower end of the first-second vertical section (112i) in the longitudinal direction. The first horizontal section (112j) may extend from the lower end of the first-second vertical section (112i) in the longitudinal direction.

[0095] This first horizontal section (112j) may be provided in a plate shape. The first horizontal section (112j) may be bent from the first-second vertical section (112i).

[0096] At this time, the first horizontal portion (112j) can be horizontally bent to the outside of the body portion (111).

[0097] Accordingly, when the prefabricated steel plate (110) is overlaid on the exterior panel (10), the first horizontal portion (112j) can be in close contact with the upper surface of the exterior panel (10), just like the body portion (111).

[0098] The first-third vertical section (112k) may be provided at one end in the longitudinal direction of the first horizontal section (112j). The first-third vertical section (112k) may extend from one end in the longitudinal direction of the first horizontal section (112j).

[0099] These first-third vertical sections (112k) may be provided in a plate shape. The first-third vertical sections (112k) may be bent from the first horizontal section (112j).

[0100] At this time, the first-third vertical section (112k) can be vertically bent at one end of the length direction of the first horizontal section (112j) to a position lower than the body section (111).

[0101] Accordingly, when the prefabricated steel plate (110) is overlaid on the exterior panel (10), the first-third vertical section (112k) can be in close contact with the side of the exterior panel (10). That is, the first-third vertical section (112k) can be inserted between adjacent exterior panels (10).

[0102] Through this, the prefabricated steel plate (110) overlaid on the exterior panel (10) can be stably maintained on the exterior panel (10).

[0104] The second assembly part (113) may be provided at the other end in the longitudinal direction of the prefabricated steel plate (110). The second assembly part (113) may be fitted and connected in the vertical direction to the first assembly part (112') of an adjacent prefabricated steel plate (110').

[0105] Accordingly, adjacent prefabricated steel plates (110, 110') can be assembled and extended in one direction.

[0106] According to one embodiment of the present invention, when the second assembly part (113) is fitted and coupled in the vertical direction to the first assembly part (112') of an adjacent prefabricated steel plate (110'), it can form a receiving space while being spaced vertically apart from the first assembly part (112') of the adjacent prefabricated steel plate (110').

[0107] In this receiving space, the upper part of the fastening member (120) exposed on the fastening part (112e), that is, the head part (121 in FIG. 8) of the fastening member (120) may be positioned.

[0108] That is, when assembling adjacent prefabricated steel plates (110, 100'), the head portion (121 in FIG. 8) of the fastening member (120) exposed on the fastening portion (112e) can be concealed by the second assembly portion (113') of the adjacent prefabricated steel plate (110').

[0109] As illustrated in FIGS. 5 and 6, according to one embodiment of the present invention, the second assembly (113) may include a second-1 vertical section (113a), a second-1 inclined section (113b), a second-2 inclined section (113c), a second-1 extended section (113d), a second-3 inclined section (113e), a second horizontal section (113f), a second-4 inclined section (113g), a second-2 extended section (113h), a second-5 inclined section (113i), and a second-6 inclined section (113j).

For example, the above-mentioned second-1 vertical section (113a) may be extended to a length corresponding to the first-2 vertical section (112i) of the first assembly section (112).

[0111] This second-1 vertical section (113a) may be provided in a plate shape. The second-1 vertical section (113a) may be bent from the body section (111). At this time, the second-1 vertical section (113a) may be bent vertically in the upward direction of the body section (111).

[0112] The above-mentioned second-1 inclined section (113b) may be provided at the upper end of the second-1 vertical section (113a) in the longitudinal direction. The above-mentioned second-1 inclined section (113b) may extend from the upper end of the second-1 vertical section (113a) in the longitudinal direction.

[0113] For example, the above 2-1 inclined section (113b) can be extended to a length corresponding to the 1-5 inclined section (112h) of the 1st assembly section (112).

[0114] This second-1 inclined portion (113b) may be provided in a plate shape. The second-1 inclined portion (113b) may be bent from the second-1 vertical portion (113a).

[0115] At this time, the second-1 inclined portion (113b) can be bent upwardly inclined toward the outside of the body portion (111).

[0116] The second-2 inclined section (113c) may be provided at the upper end of the second-1 inclined section (113b) in the longitudinal direction. The second-2 inclined section (113c) may extend from the upper end of the second-1 inclined section (113b) in the longitudinal direction.

[0118] This second-2 inclined portion (113c) may be provided in a plate shape. The second-2 inclined portion (113c) may be bent from the second-1 inclined portion (113b).

[0119] At this time, the second-2 inclined portion (113c) can be bent upwardly inclined toward the inside of the body portion (111).

At this time, the second-1 extension (113d) may extend inwardly into the body portion (111).

[0121] The second assembly part (113) can form a groove larger than the first assembly part (112) downward through the second-1 extension part (113d) and the second-2 extension part (113h) described later, and accordingly, when assembling adjacent prefabricated steel plates (110, 110'), a receiving space can be formed between them while being spaced apart from the first assembly part (112').

[0122] The second-third inclined portion (113e) may be provided at one end in the longitudinal direction of the second-first extension portion (113d). The second-third inclined portion (113e) may extend from one end in the longitudinal direction of the second-first extension portion (113d).

[0123] These second-third inclined portions (113e) may be provided in a plate shape. The second-third inclined portion (113e) may be bent from the second-first extended portion (113d).

[0124] At this time, the second-third inclined portion (113e) can be bent upwardly inclined toward the outside of the body portion (111).

[0125] These second-third inclined sections (113e) can be extended to a position higher than the fastening section (112e) of the first assembly section (112).

[0126] The second horizontal section (113f) may be provided at the upper end of the second-third inclined section (113e) in the longitudinal direction. The second horizontal section (113f) may extend from the upper end of the second-third inclined section (113e) in the longitudinal direction.

[0127] This second horizontal section (113f) may be provided in a plate shape. The second horizontal section (113f) may be bent from the second-third inclined section (113e). At this time, the second horizontal section (113f) may be horizontally bent to the outside of the body section (111).

[0128] According to one embodiment of the present invention, when assembling adjacent prefabricated steel plates (110, 110'), the second horizontal portion (113f) is spaced vertically apart from the fastening portion (112e) of the first assembly portion (112) and can conceal the head portion (121 in FIG. 8) of the fastening member (120) that is exposed above the fastening portion (112e).

[0129] The second-fourth inclined portion (113g) may be provided at one end in the longitudinal direction of the second horizontal portion (113f). The second-fourth inclined portion (113g) may extend from one end in the longitudinal direction of the second horizontal portion (113f).

[0130] These second-fourth inclined portions (113g) may be provided in a plate shape. The second-fourth inclined portion (113g) may be bent from the second horizontal portion (113f).

[0131] At this time, the second-4th inclined portion (113g) can be bent symmetrically with respect to the second-3rd inclined portion (113e). That is, the second-4th inclined portion (113g) can be bent downwardly inclined toward the outside of the body portion (111).

[0132] The second-2 extension (113h) may be provided at the longitudinal lower end of the second-4 inclined portion (113g).

[0133] That is, the second-2 extension (113h) can be extended from the lower end of the second-4 inclined portion (113g) in the longitudinal direction to the inside of the body portion (111).

[0134] As described above, the second-2 extension (113h), together with the second-1 extension (113d), can form a groove larger than the first assembly (112) on the lower side of the second assembly (113).

[0135] Through this, when assembling adjacent prefabricated steel plates (110, 110'), a receiving space for the head portion (121 in FIG. 8) of a fastening member (120) having the first prefabricated portion (112) as the bottom surface can be formed on the lower side of the second assembly portion (113).

[0136] The second-fifth inclined portion (113i) may be provided at one end in the longitudinal direction of the second-2 extension portion (113h). The second-fifth inclined portion (113i) may extend from one end in the longitudinal direction of the second-2 extension portion (113h).

[0137] These second-fifth inclined portions (113i) may be provided in a plate shape. The second-fifth inclined portion (113i) may be bent from the second-2 extension portion (113h).

[0138] At this time, the second-fifth inclined portion (113i) may be symmetrical with respect to the second-2 inclined portion (113c). That is, the second-fifth inclined portion (113i) may be bent downwardly inclined toward the inside of the body portion (111).

[0139] The second-sixth inclined section (113j) may be provided at the longitudinal lower end of the second-fifth inclined section (113i). The second-sixth inclined section (113j) may extend from the longitudinal lower end of the second-fifth inclined section (113i).

[0140] These second-sixth inclined portions (113j) may be provided in a plate shape. The second-sixth inclined portions (113j) may be bent downwardly inclined toward the outside of the body portion (111).

[0141] According to one embodiment of the present invention, when assembling adjacent prefabricated steel plates (110, 110'), the 2-6 inclined portion (113j) can be in close contact with the 1-1 inclined portion (112b) of the 1st assembly portion (112').

[0142] At this time, the 2-6 slope portion (113j) may have a second slope greater than the first slope formed by the 1-1 slope portion (112b).

[0143] Accordingly, when assembling adjacent prefabricated steel plates (110, 110'), the 2-6 inclined section (113j) can be pressed against the 1-1 inclined section (112b), thereby primarily blocking the penetration of melted snow or rainwater.

[0144] As illustrated in FIG. 7, a roof panel assembly (100) according to one embodiment of the present invention may have a double waterproof structure.

[0145] That is, according to one embodiment of the present invention, when assembling adjacent prefabricated steel plates (110, 110'), the second-6 inclined portion (113j') of the second prefabricated steel plate (113') provided on the adjacent prefabricated steel plate (110') is pressed against the first-1 inclined portion (112b) of the first prefabricated steel plate (112), thereby primarily blocking the penetration of melted snow or rainwater.

[0146] Nevertheless, the water that has penetrated into the assembly area of ​​the first assembly part (112) and the second assembly part (113') can be discharged to the outside before reaching the fastening part (112e) through the drainage channel (112d) provided on the upstream side of the fastening part (112e).

[0147] A roof panel assembly (100) according to one embodiment of the present invention can prevent corrosion of the fastening member (120) and completely solve the problem of leakage through this double waterproof structure.

[0149] The above fastening member (120) can be sequentially connected through the assembly steel plate (110) and the exterior panel (10) using the fastening part (112e) of the first assembly part (112) as the fastening point.

[0150] Through this, the fastening member (120) can fasten the prefabricated steel plate (110) and the exterior panel (10) as a single unit.

[0151] At this time, as described above, after the fastening is completed, the upper portion of the fastening member (120) exposed on the fastening portion (112e) can be concealed by the second assembly portion (113') of the adjacent prefabricated steel plate (110') when the second assembly portion (113') of the adjacent prefabricated steel plate (110') is fitted and coupled to the first assembly portion (112) in the vertical direction.

[0152] As illustrated in FIG. 8, the fastening member (120) may be provided with a bolt. Accordingly, the fastening member (120) may be divided into a head portion (121) and a body portion (122).

[0153] The head portion (121) may be defined as the longitudinal upper portion of a fastening member (120) that is exposed or protrudes onto the fastening portion (112e) of the first assembly portion (112) when fastening is completed, and is concealed by the second assembly portion (113') of an adjacent assembly steel plate (110').

[0154] The body portion (122) may extend in one direction from the lower side of the head portion (121). According to one embodiment of the present invention, the body portion (122) may include a first screw thread (122a).

[0155] The first screw thread (122a) may be formed on the upper longitudinal side of the body portion (122). At this time, the body portion (122) may further include a second screw thread (122b). The second screw thread (122b) may be formed on the lower longitudinal side of the body portion (122).

[0156] At this time, the first screw thread (122a) and the second screw thread (122b) may not be connected to each other in the longitudinal direction of the body part (122). That is, the first screw thread (122a) and the second screw thread (122b) may be provided discontinuously.

[0157] However, this is just an example, and it goes without saying that screw threads can be formed along the entire length of the body part (122).

[0159] Hereinafter, a roof panel assembly according to another embodiment of the present invention will be described with reference to FIGS. 9 and FIGS. 10.

[0161] FIG. 9 is a schematic diagram for explaining a roof panel assembly according to another embodiment of the present invention, and FIG. 10 is a schematic diagram for explaining the joining structure of adjacent prefabricated steel plates in a roof panel assembly according to another embodiment of the present invention.

[0163] Referring to FIGS. 9 and 10, a roof panel assembly (200) according to another embodiment of the present invention may include a prefabricated steel plate (110), a fastening member (120), and a reinforcing plate (230).

[0165] Another embodiment of the present invention differs from the first embodiment of the present invention only in that a reinforcing plate has been added; therefore, the same reference numerals are assigned to the remaining identical components, and a detailed description thereof is omitted.

[0167] According to another embodiment of the present invention, the reinforcing plate (230) may be positioned on one side in the longitudinal direction of an exterior panel (10), such as a single steel plate or a sandwich panel.

[0168] At this time, one side in the longitudinal direction of the exterior panel (10) may be a location where a clamp (C) supporting the solar panel is installed.

[0169] That is, the reinforcing plate (230) is positioned where the solar panel is to be installed, and can reinforce the strength of the position so that the solar panel can be stably supported.

[0170] These reinforcing plates (230) can be placed on the fastening portion (112e) of the first assembly (112) in which a drainage channel (112d) is provided on the upstream side.

[0171] Accordingly, according to another embodiment of the present invention, the fastening member (120) can be sequentially connected to the prefabricated steel plate (110) and the exterior panel (10) through the reinforcing plate (230).

[0172] According to another embodiment of the present invention, such a reinforcing plate (230) may include a plate body (231) and a plate wing (232).

[0173] The above plate body (231) may be provided in a plate shape. This plate body (231) may be seated on the fastening portion (112e) and may provide a fastening surface of the fastening member (120).

[0174] The plate wing (232) may be provided at both ends in the longitudinal direction of the plate body (231). The plate wing (232) may extend from both ends in the longitudinal direction of the plate body (231).

[0175] These plate wings (232) may be provided in a plate shape. The plate wings (232) may be folded from the plate body (231).

[0176] At this time, the plate wing (232) can be bent downwardly inclined toward the outside of the plate body (231).

[0177] According to another embodiment of the present invention, a plate wing (232) provided at one end of a plate body (231) may be positioned on a drain (112d) of a first assembly part (112).

[0178] Additionally, the plate wing (232) provided at the other end of the plate body (231) may be positioned on the first-third inclined portion (112f) of the first assembly part (112).

[0179] Meanwhile, the lower jig of the clamp (C) supporting the solar panel can be divided into a left jig and a right jig.

[0180] The jigs on both sides of the clamp (C) can be attached to the second assembly (113) in a manner that wraps around the second assembly (113). At this time, the jigs on both sides of the clamp (C) can be pressed in a direction that meets each other by means of a bolt.

[0181] Accordingly, the lower jig of the clamp (C) can be pressed against the outer surface of the second assembly part (113).

[0182] According to another embodiment of the present invention, the second assembly part (113) may be provided in a form that fits with the lower jig of the clamp (C) so that the lower jig of the clamp (C) can be pressed against the outer surface.

[0183] According to another embodiment of the present invention, even if melted snow or rainwater penetrates into the assembly area between adjacent prefabricated steel plates (110, 110') at the location where the clamp (C) supporting the solar panel is installed, the penetrating water can be smoothly discharged to the outside at the beginning of the penetration through the drainage channel (112d) provided on the upstream side of the location where the fastening member (120) is fastened, before the penetrating water reaches the location where the fastening member (120) is fastened, thereby preventing leakage.

[0185] According to the embodiment of the present invention described above, by providing a drainage channel in the roof panel assembly, even if unintended water penetrates between the first assembly and the second assembly, the water can be forcibly discharged through the drainage channel, thereby minimizing leakage.

[0186] In the roof panel assembly according to an embodiment of the present invention, the prefabricated steel plate may be a new single steel plate or may refer to the upper steel plate of a sandwich panel. Alternatively, the roof panel assembly according to an embodiment of the present invention may be used for overlay repair of an aging roof. In this case, the roof panel assembly according to an embodiment of the present invention may be installed on an existing aging single steel plate or an existing aging sandwich panel.

[0188] Although the present invention has been described in detail using preferred embodiments, the scope of the invention is not limited to specific embodiments and should be interpreted by the appended claims. Furthermore, those skilled in the art will understand that many modifications and variations are possible without departing from the scope of the invention. Explanation of the symbols
