Adhesive fixing structure for roof-mounted photovoltaic power generation system

[0001] The present invention relates to an adhesive fixing structure for a roof-mounted photovoltaic power generation device, and more specifically, to an adhesive fixing structure for a roof-mounted photovoltaic power generation device capable of stably supporting and installing the photovoltaic power generation device on a roof panel in a non-drilling manner.

[0002] Recently, interest in the development of energy sources such as wind, tidal, solar, and geothermal power is growing day by day as a means to overcome the energy crisis caused by the depletion of fossil fuels and to address environmental pollution and global warming.

[0003] Representative examples of such power generation systems include wind power, tidal power, and photovoltaic or solar thermal power systems. Among these devices, photovoltaic power systems have a relatively simple structure that allows for installation in urban areas or ordinary homes, and prefabricated buildings, which offer lower construction costs, are frequently used to install these systems.

[0004] In the case of prefabricated buildings, a roof frame consisting of horizontal and vertical frames is installed at the top of the columns, and roof panels are installed on top of it; support frames and solar panels are then installed on these roof panels for power generation.

[0005] As an example of installing solar panels on the roof panels of a prefabricated building, Korean Published Patent No. 10-2020-0038086 (Patent Document 1) discloses a "support frame fixing structure for a solar power generation device for roof installation," and Korean Published Patent No. 10-2015-0117513 (Patent Document 2) discloses a "prefabricated roof fixing structure for a solar array."

[0006] However, conventional technologies such as those described in the aforementioned patent documents 1 and 2 require forming holes that penetrate the roof panels for the installation of fixing bolts, making the work difficult. Additionally, separate sealing work is required to maintain airtightness so that rainwater does not enter through the drilled holes. Furthermore, as time passes, if rainwater repeatedly enters the area where the fixing bolts are installed, corrosion occurs and leakage occurs.

[0007] The present invention aims to solve the aforementioned conventional problems by providing an adhesive fixing structure for a roof-mounted solar power generation device that can resolve the corrosion and leakage problems of conventional roof panels caused by the inflow of rainwater or foreign substances by installing the support posts of the solar power generation device on the roof panel using a non-drilling method.

[0010] The adhesive fixing layer of the adhesive fixing structure of the roof-mounted photovoltaic power generation device according to the present invention comprises a base layer applied between the roof coupling part and the roof panel, a connecting part introduced from the base layer into the through hole, and an expanded projection extended from the connecting part through the through hole to occupy the area around the through hole on the upper surface of the roof coupling part, wherein the base layer, the connecting part, and the expanded projection are formed integrally.

[0011] The adhesive fixing structure of a roof-mounted photovoltaic power generation device according to the present invention further comprises a plurality of intermediate fixing parts that fix the roof coupling part and the support column coupling part to each other; wherein the intermediate fixing part comprises an intermediate fixing bolt and an intermediate fixing nut that are coupled to penetrate the roof coupling part and the support column coupling part vertically.

[0012] The adhesive fixing structure of the roof-mounted photovoltaic power generation device according to the present invention is characterized in that a filling space is formed between the roof coupling part and the roof panel, wherein the roof coupling part is spaced apart from the roof panel by a certain distance by the intermediate fixing part, so that the adhesive fixing layer can be accommodated with a certain thickness.

[0013] The adhesive fixing structure of the roof-mounted photovoltaic power generation device according to the present invention is characterized in that a gap maintaining portion is formed on the lower surface of the roof connecting portion facing the upper surface of the roof panel, which maintains a uniform gap between the roof connecting portion and the roof panel and maintains a uniform thickness of the adhesive fixing layer applied between the roof connecting portion and the roof panel.

[0016] The adhesive fixing structure of the roof-mounted photovoltaic power generation device according to the present invention can solve the problems of corrosion and leakage of conventional roof panels caused by the inflow of rainwater or foreign substances by installing the support of the photovoltaic power generation device on the roof panel using a non-drilling method.

[0024] Hereinafter, an adhesive fixing structure of a roof-mounted photovoltaic power generation device according to a preferred embodiment of the present invention will be described in detail with reference to the attached drawings.

[0025] FIGS. 1 to 3 illustrate an adhesive fixing structure of a roof-mounted photovoltaic power generation device according to the present invention. Referring to FIGS. 1 to 3, the adhesive fixing structure of a roof-mounted photovoltaic power generation device according to the first embodiment of the present invention may be configured to include a roof coupling part (100), an adhesive fixing layer (200), a support column coupling part (300), an intermediate fixing part (400), and a support column fixing part (500).

[0026] The roof joint (100) is positioned on the roof panel (10) to occupy or surround a portion of the ridge (11) on one side of the roof panel (10) and a portion of the valley (12) surrounding both sides of the ridge (11). As the adhesive fixing layer (200) described later is applied to a certain thickness and hardened, the roof joint (100) is bonded and fixed to the roof panel (10) at a certain distance without coming into contact with the surface of the ridge (11) and the valley (12).

[0027] More specifically, the roof joint (100) may be configured to include an upper plate (110), a first side plate (121) and a second side plate (122), a first lower plate (131) and a second lower plate (132).

[0028] The top plate (110) is a part positioned to face the upper surface of the ridge portion (11) on one side, and is formed in a flat plate shape parallel to the upper surface of the ridge portion (11), and is formed to have a width corresponding to the ridge portion (11) or a slightly larger width.

[0029] The first side plate (121) and the second side plate (122) are extended downwardly at an angle from both sides of the left and right longitudinal edges of the top plate (110) to face the sides of the top plate (11), respectively.

[0030] The first lower plate (131) and the second lower plate (132) are extended horizontally from the respective ends of the first and second side plates (122) to face the upper surface of the valley (12) around both sides of the ridge (11).

[0031] As previously explained, the top plate (110), the first side plate and the second side plate (122), the first bottom plate (131), and the second bottom plate (132) constituting the roof joint part (100) are adhered to and fixed to the roof panel (10) at a certain distance from the roof panel (10) by curing the adhesive fixing layer (200) applied to a certain thickness.

[0032] The adhesive fixing layer (200) is applied to one side surface of the roof panel (10) corresponding to the portion where the roof joint (100) is placed, thereby bonding and fixing the roof joint (100) to the roof panel (10). The adhesive fixing layer (200) may be a liquid that is fluid when contained in a sealed container or within a certain period of time after exposure to the outside air, and may be an adhesive that hardens when exposed to the outside air for a certain period of time or longer. As the adhesive, a conventional industrial adhesive capable of bonding metals, plastics, etc., may be applied.

[0033] The adhesive fixing layer (200) can be applied to have a certain thickness between the roof joint (100) and the roof panel (10). After applying the adhesive fixing layer (200) to the surface of the roof panel (10), when attaching the roof joint (100) to the roof panel (10), it is preferable to allow a portion of the adhesive fixing layer (200) between the roof joint (100) and the roof panel (10) to cure in a state where it flows out to the edges of the roof joint (100) and to the outside, so that the adhesive fixing layer (200) occupies an area larger than the area of ​​the roof joint (100). Additionally, the adhesive fixing layer (200) can be formed thicker than the adhesive fixing layer (200) between the roof joint (100) and the roof panel (10) by extending the adhesive fixing layer (200) to the edge and outside of the roof joint (100), thereby improving the adhesive and fixing ability of the roof joint (100) to the roof panel (10).

[0034] The support column connecting part (300) is a part for installing a support column (20) that supports a solar module of a solar power generation device, and its lower part is connected to the roof connecting part (100), and the support column (20) of the solar power generation device is connected to its upper part.

[0035] More specifically, the support joint (300) may be configured to include a horizontal plate (310), a first vertical plate (321), and a second vertical plate (322).

[0036] The horizontal plate (310) is a part that is connected to the upper plate (110) of the roof joint (100), is arranged to be in contact with and parallel to the upper plate (110) of the roof joint (100), and is formed in the shape of a square flat plate. The horizontal plate (310) is formed with a width or length longer than the width of the upper plate (110) of the roof joint (100). A portion of the bottom surface of the horizontal plate (310) is connected in close contact with the upper surface of the upper plate (110) of the roof joint (100).

[0037] The first vertical plate (321) and the second vertical plate (322) each extend upward from opposite sides of the horizontal plate (310) so as to be orthogonal to the horizontal plate (310). The first vertical plate (321) and the second vertical plate (322) each extend from opposite sides of the horizontal plate (310) arranged in a direction parallel to the direction in which the ridge portion (11) on the roof panel (10) is arranged. The gap between the first vertical plate (321) and the second vertical plate (322) is formed to correspond to the thickness of the support (20) or a slightly wider gap.

[0038] The intermediate fixing part (400) connects and fixes the roof connecting part (100) and the support connecting part (300) to each other, and can be configured to include an intermediate fixing bolt (410) and an intermediate fixing nut (420). In this embodiment, two intermediate fixing parts (400) are applied, but a larger number of intermediate fixing parts (400) can be applied.

[0039] A plurality of intermediate fixing holes (430) are formed at corresponding positions on the upper plate (110) of the roof coupling part (100) and the horizontal plate (310) of the support coupling part (300) so that the roof coupling part (100) and the support coupling part (300) can be coupled and fixed to each other through the intermediate fixing part (400). The intermediate fixing holes (430) are formed to penetrate vertically through each of the upper plate (110) and the horizontal plate (310).

[0040] The intermediate fixing part (400) may fix the roof connecting part (100) and the supporting part (300) to each other by passing the intermediate fixing bolt (410) through the intermediate fixing holes (430) from the upper plate (110) side to the horizontal plate (310) side, and then fastening the intermediate fixing nut (420) to the end of the intermediate fixing bolt (410) exposed on the bottom surface of the horizontal plate (310), or conversely, the roof connecting part (100) and the supporting part (300) may fix the roof connecting part (100) and the supporting part (300) to each other by passing the intermediate fixing bolt (410) through the intermediate fixing holes (430) from the horizontal plate (310) side to the upper plate (110) side, and then fastening the intermediate fixing nut (420) to the end of the intermediate fixing bolt (410) exposed on the upper surface of the upper plate (110).

[0041] In this embodiment, an intermediate fixing part (400) is applied to the configuration that connects the roof connecting part (100) and the support connecting part (300) to each other; however, the roof connecting part (100) and the support connecting part (300) can be connected and fixed to each other by welding. In this case, welding can be performed along the boundary where the top plate part (110) and the horizontal part meet. Additionally, both the method using the intermediate fixing part (400) and the method using welding can be applied to the configuration that connects the roof connecting part (100) and the support connecting part (300) to each other.

[0042] As the head portion of the intermediate fixing bolt (410) or the intermediate fixing nut (420) of the intermediate fixing part (400) is positioned below the upper plate part (110), that is, between the upper plate part (110) and the uppermost part of the floor part (11), the roof connecting part (100) is spaced upward at a certain distance from the roof panel (10), and a filling space can be formed between the roof connecting part (100) and the roof panel (10) to accommodate and fill an adhesive fixing layer (200) of a certain thickness.

[0043] The support fixing part (500) is configured to connect and fix the support (20) to the support connecting part (300) and may include at least one support fixing bolt (510) and a support fixing nut (520). In order to connect and fix the support (20) to the support connecting part (300) using the support fixing part (500), at least one support fixing hole (323) is formed in the first vertical plate (321) and the second vertical plate (322) of the support connecting part (300). The support fixing hole (323) is formed to penetrate horizontally through each of the first vertical plate (321) and the second vertical plate (322), and is formed at a position corresponding to each other on the first vertical plate (321) and the second vertical plate (322). And, at least one support fastening hole (21) is formed in the support (20) at a position corresponding to the support fixing hole (323) and penetrating the support (20).

[0044] The support fixing part (500) can connect and fix the support (20) to the support connecting part (300) by passing the support fixing bolt (510) through the support fixing hole (323) of the first vertical plate (321) or the second vertical plate (322), the support fastening hole (21) of the support (20), and the support fixing hole (323) of the second vertical plate (322) or the first vertical plate (321), and then fastening the support fixing nut (520) to the end of the support fixing bolt (510) exposed to the outside of the support connecting part (300).

[0045] The adhesive fixing structure of the roof-mounted photovoltaic power generation device according to the present invention, as described above, can firmly and easily install and fix the support (20) of the photovoltaic power generation device to the roof panel (10) without drilling the roof panel (10), thereby preventing leakage and corrosion of the roof panel (10).

[0046] Meanwhile, the adhesive fixing structure of the roof-mounted photovoltaic power generation device according to the present invention may utilize a roof coupling part (100) having a through hole (140) formed therein.

[0047] Referring to FIG. 4, a plurality of through holes (140) can be formed in the roof joint (100) so that a portion of the adhesive fixing layer (200) between the roof joint (100) and the roof panel (10) can pass through and flow out to the upper surface of the roof joint (100).

[0048] The through hole (140) can be formed to penetrate vertically the first side plate (121) and the second side plate (122), and the first bottom plate (131) and the second bottom plate (132), excluding the top plate (110) of the roof joint part (100).

[0049] After applying the adhesive fixing layer (200) to the roof panel (10) and attaching the roof joint part (100) to the roof panel (10), the adhesive fixing layer (200) flows out along the through hole (140) to the upper surface of the first side plate part (121) and the second side plate part (122) of the roof joint part (100), and to the upper surface of the first bottom plate part (131) and the second bottom plate part (132), and the adhesive fixing layer (200) that flows out to the upper surface of the roof joint part (100) hardens in that state.

[0050] According to the structure of the roof joint part (100) in which the through hole (140) is formed, the adhesive fixing layer (200) that has been cured can be divided into a base layer (210), a connecting part (220), and an expanded protrusion part (230).

[0051] The base layer (210) is a portion applied between the roof joint (100) and the roof panel (10), and when cured after application, it bonds and fixes the bottom surface of the roof joint (100) and the top surface of the roof panel (10).

[0052] The connecting portion (220) is formed by the adhesive fixing layer (200) flowing into and hardening inside the through hole (140) and is formed integrally with the base layer (210).

[0053] The expanded protrusion (230) is a hardened portion formed by the adhesive fixing layer (200) passing through the through hole (140) and flowing out around the through hole (140) on the upper surface of the roof joint (100). It is expanded to occupy a certain area of ​​the upper surface of the roof joint (100) around the through hole (140) and is formed integrally with the connecting portion (220). By expanding the expanded protrusion (230) to an area larger than the through hole (140), it is possible to prevent the roof joint (100) from separating and detaching from the base layer (210).

[0054] The adhesive fixing structure of the roof-mounted photovoltaic power generation device according to the second embodiment of the present invention, as described above, can effectively suppress and prevent the roof-mounted part (100) from separating and detaching from the base layer (210) by having the adhesive fixing layer (200) have the same or similar function as a rivet, through which the connecting part (220) and the expanding protrusion part (230) after curing are formed by the roof-mounted part (100) structure having a through hole (140). That is, the base layer (210) of the adhesive fixing layer (200) primarily adheres and fixes the roof-mounted part (100), and the connecting part (220) and the expanding protrusion part (230) secondarily adhere and fix the roof-mounted part (100), thereby improving the adhesive force and fixing force for the roof-mounted part (100).

[0055] In addition, multiple through holes are formed throughout the roof joint part (100) so that the adhesive fixing layer (200) can be cured relatively uniformly.

[0056] Meanwhile, the adhesive fixing structure of the roof-mounted photovoltaic power generation device according to the present invention may utilize a roof coupling part (100) equipped with a spacing part (150).

[0057] Referring to FIGS. 5 and 6, the roof joint (100) is further provided with a spacing member (150), and the spacing member (150) maintains a uniform spacing between the roof joint (100) and the roof panel (10) on the lower surface of the roof joint (100) facing the upper surface of the roof panel (10), and maintains a uniform thickness of the adhesive fixing layer (200) applied between the roof joint (100) and the roof panel (10).

[0058] More specifically, the spacing member (150) protrudes downward for a certain length from the bottom surface of the roof joint member (100), extends along the left and right length directions of the roof joint member (100), and is spaced apart at a certain distance along the upper and lower width directions of the roof joint member (100). The spacing member (150) is continuously formed along the bottom surfaces of the first side plate member (121) and the second side plate member (122), and the bottom surfaces of the first lower plate member (131) and the second lower plate member (132).

[0059] The above spacing member (150) can maintain a uniform spacing between the roof joint member (100) and the roof panel (10) by supporting the roof joint member (100) so that it does not tilt to either side of the left or right direction centered on the roof panel (10) as the upper plate (110) of the roof joint member (100) and the uppermost part of the roof panel (10) are spaced apart by the intermediate fixing member (400). Accordingly, the adhesive fixing layer (200) applied and received in the filling space formed between the roof joint member (100) and the roof panel (10) by the intermediate fixing member (400) can be cured while maintaining a uniform thickness. Furthermore, as the thickness of the adhesive fixing layer (200) is maintained uniformly, the support (20) of the solar power generation device can be stably supported and fixed.

[0060] In addition, the adhesive fixing structure of the roof-mounted photovoltaic power generation device according to the present invention may utilize a roof coupling part (100) having an adhesive receiving groove (160) formed therein.

[0061] Referring to FIGS. 7 and 8, a plurality of adhesive receiving grooves (160) are formed on the bottom surface of the roof joint (100) facing the upper surface of the roof panel (10).

[0062] More specifically, the adhesive receiving groove (160) is recessed from the bottom surface of the roof joint (100) to a certain depth into the roof joint (100) so that the adhesive fixing layer (200) can be partially inserted into the roof joint (100), extends along the left-right length direction of the roof joint (100), and is spaced apart along the upper-low width direction of the roof joint (100). The adhesive receiving groove (160) is continuously formed along the bottom surfaces of the first side plate (121) and the second side plate (122), and the bottom surfaces of the first bottom plate (131) and the second bottom plate (132).

[0063] The adhesive fixing layer (200) that enters the adhesive receiving groove (160) can increase the contact area and adhesive area with the roof joint part (100) to improve adhesive strength and fixing strength.

[0064] In addition, the adhesive fixing structure of the roof-mounted photovoltaic power generation device according to the present invention may further include a reinforcing part (600).

[0065] Referring to FIGS. 9 and 10, the reinforcing member (600) may be configured to include a plurality of reinforcing ribs that extend from the support member (300) to contact and support the roof member (100) when connecting the roof member (100) and the support member (300), thereby reinforcing the space between the support member (300) and the roof member (100).

[0066] The reinforcing ribs may be configured to include a first reinforcing rib (610) and a second reinforcing rib (620) located on the left and right sides, respectively, centered on the left and right length directions of the horizontal plate (310), and each of the first reinforcing rib (610) and the second reinforcing rib (620) may be spaced apart along the upper and lower width directions of the horizontal plate (310).

[0067] The first reinforcing rib (610) extends downward from one side in the longitudinal direction of the horizontal plate (310), and a first contact inclined surface is formed on one side to contact and be supported by the first side plate portion (121).

[0068] The second reinforcing rib (620) extends downward from the other side in the longitudinal direction of the horizontal plate (310), and on one side, a second contact inclined surface is formed so as to contact and be supported by the second side plate portion (122).

[0069] In this embodiment, the reinforcing member (600) is formed integrally with the support member (300), but alternatively, it may be formed integrally with the roof member (100) by extending from the roof member (100). In this case, the reinforcing member (600) may be configured to include a plurality of reinforcing ribs that extend from the roof member (100) to contact and support the support member (300) when the roof member (100) and the support member (300) are joined together, thereby reinforcing the space between the support member (300) and the roof member (100).

[0070] By stably reinforcing and supporting the support joint (300) with respect to the roof joint (100) through the above-mentioned reinforcing part (600), damage or breakage such as bending or breaking of the support joint (300) due to external force applied to the support (20) side of the photovoltaic power generation device can be prevented.

[0071] The adhesive fixing structure of the roof-mounted photovoltaic power generation device according to the present invention described above has been explained with reference to the attached drawings, but this is merely illustrative, and those skilled in the art will understand that various modifications and equivalent alternative embodiments are possible therefrom.

[0072] Therefore, the true scope of technical protection of the present invention should be determined solely by the technical concept of the appended claims.
