Description

Detachable functional building-integrated solar power generation system and installation method thereof

[0001] The present invention relates to a building-integrated solar power generation system and an installation method thereof, and more particularly, to a detachable functional building-integrated solar power generation system and an installation method thereof, which secures earthquake resistance and insulation performance by attaching solar modules on both sides to an exterior wall structure by a double-fitting method and attaching the solar modules in a sealed state, thereby enabling easy and quick installation and maintenance through simple attachment and detachment along with firm fixation.

[0002] Building Integrated Photovoltaics (BIPV) is a method of producing electrical energy by installing solar cell modules on the building envelope. It can be used as both an existing building envelope and an energy production tool, so it is expected to have a dual effect.

[0003] These BIPV systems are emerging as a solution that can overcome the limitations of countries like Korea, which have a small land area and densely packed buildings, because they do not require separate installation space like existing solar power generation systems.

[0004] BIPV systems are installed on the exterior walls, curtain walls, etc. of buildings through separate fastening structures as shown in the patent documents below. However, existing fastening structures do not have functions such as insulation or waterproofing in addition to fastening and bonding, so there are problems such as the significant influence of outside air between solar modules and the possibility of water inflow. In addition, there are problems such as vulnerability to vibrations caused by earthquakes and weak bonding strength.

In the following description of the present invention, if a detailed description of a known function or configuration is determined to unnecessarily obscure the gist of the present invention, such detailed description will be omitted. Throughout the specification, when a part is said to "include" a certain component, unless specifically stated otherwise, this does not mean that other components are excluded, but rather that other components may be included.

[0053]

[0054] Referring to FIGS. 1 to 3, a detachable functional building-integrated solar power generation system according to one embodiment of the present invention includes: an exterior wall structure (1) formed on an exterior wall of a building; a first fixing unit (2) that is coupled to the exterior wall structure (1) by a fitting method; a pair of second fixing units (3) that are fitted to both sides of the first fixing unit (2) and each have an adjacent solar module (P) attached to them; and a closing means (4) that seals between the solar modules attached to the pair of second fixing units (3).

[0055] The building-integrated photovoltaic power generation system according to the present invention enables quick installation and easy maintenance and repair through a structure that is fastened in a clamping manner. In addition, the double clamping method of the first fixing unit (2) and the second fixing unit (3) with insulation and earthquake resistance functions, and the sealed blocking between the solar modules (P) that are joined on both sides, further enhances the earthquake resistance and insulation performance.

[0056] Hereinafter, the upper and lower directions of the drawing will be explained assuming the upper and lower directions, and the upper direction in the drawing means the outer direction of the outer wall structure (1) that is perpendicular to the outer wall structure (1). Therefore, considering that the outer wall structure (1) is generally installed in a direction perpendicular to the ground, the upper direction in the drawing may mean the outer direction of the outer wall structure (1) that is parallel to the ground, and when the outer wall structure (1) forms an angle that is not perpendicular to the ground, the upper direction in the drawing may also form a certain angle with the ground depending on the angle that the outer wall structure (1) forms with the ground.

[0057] The above-mentioned exterior wall structure (1) is a configuration that forms the exterior wall of a building, and may refer to an exterior material, a curtain wall, etc. The above-mentioned exterior wall structure (1) may have a fitting projection (11) formed to protrude upward, and the above-mentioned first fixing unit (2) is fitted into the fitting projection (11).

[0058] The first fixing unit (2) is configured to be joined to the outer wall structure (1) by a fitting method, and is fitted into the fitting projection (11). In addition, the second fixing units (3) on both sides to which the solar modules (P) are attached are joined by a fitting method to the first fixing unit (2). In particular, the first fixing unit (2) can absorb vibration and have a heat insulating function, and can improve earthquake-resistant performance and achieve effective heat insulation by absorbing vibration and blocking heat at the point where the solar modules (P) are connected. Therefore, the first fixing unit (2) can secure earthquake-resistant and heat insulating performance while simply joining and connecting the solar modules (P) on both sides by a fitting method, thereby improving functionality along with quick installation and maintenance. To this end, the first fixing unit (2) can include a unit body (21), an earthquake-resistant insulating rubber (22), and a fixing piece (23).

To this end, the unit body (21) may include a support protrusion (211) and a joining portion (212).

[0060] The above-mentioned support protrusion (211) is configured to protrude downward from both ends of the unit body (21), and an earthquake-resistant insulating rubber (22) can be fitted between the support protrusions (211).

In particular, the connecting portion (212) may maintain a stable fitting state through its unique structure, and may allow the fitting portion (311) and the fixing portion (312) of the second fixing unit (3), which will be described later, to be fitted and fixed. To this end, the connecting portion (212) may include an insertion groove (212a), a fitting groove (212b), and a convex end (212c), as illustrated in FIG. 3.

[0062] The above insertion groove (212a) is formed by being recessed to a certain depth from the top to the bottom of the joint portion (212), into which the insertion projection (311b) of the second fixing unit (3) to be described later is inserted, and is formed as a pair on both sides so that the insertion projections (311b) of each of the second fixing units (3) on both sides can be inserted.

[0063] The above fitting groove (212b) is configured to be recessed outward at one point within the insertion groove (212a), and can be recessed in a round shape at one point on the upper side so that the protruding surface (311b-1) of the insertion projection (311b), which will be described later, can be fitted therein. Accordingly, the fitting groove (212b) can be formed in a position and shape corresponding to the protruding surface (311b-1), and the protruding surface (311b-1) of the insertion projection (311b) fitted into the insertion groove (212a) can be fixed in close contact with the fitting groove (212b).

[0064] The above convex end (212c) is formed to protrude outward from an outer point of the connecting portion (212), and may be formed at a height corresponding to the fitting groove (212b). The above convex end (212c) may be formed to protrude outward in a rounded manner, and may be formed at a position and shape corresponding to the recessed groove (312a) of the later-described mounting portion (312) of the second fixing unit (3), so that the second fixing unit (3) may be stably fixed to the connecting portion (212).

[0065] The above earthquake-resistant insulating rubber (22) is configured to be fixed to the lower side of the unit body (21) to absorb vibration and block heat, and may be formed of a rubber material having a certain elasticity, and may be formed of, for example, a rubber foam insulation material. The earthquake-resistant insulating rubber (22) may be inserted and attached between the support protrusions (211) of the unit body (21), and the fitting projection (11) of the outer wall structure (1) is fitted therein. To this end, the earthquake-resistant insulating rubber (22) may have a fitting hole (221) formed through the center so that the fitting projection (11) is fitted therein, and protrusions (222) may be formed at both ends so that they are fitted to the lower side of the support protrusions (211). The above protrusion (222) is formed by protruding from both sides from the lower side of the earthquake-resistant rubber (22), and is inserted into the lower side of the support protrusion (211). Accordingly, the earthquake-resistant rubber (22) is stably fixed by the support protrusion (211), and the earthquake-resistant rubber (22) is inserted between the support protrusion (211) and the outer wall structure (1) by the elastic earthquake-resistant rubber (22), thereby further enhancing the earthquake-resistant performance through vibration absorption.

[0066] The above-mentioned fixed piece (23) is configured to fix the first fixed unit (2) to the outer wall structure (1), and is formed with a screw or the like, and is fastened to the outer wall structure (1) by penetrating the unit body (21) and the earthquake-resistant insulating rubber (22) as shown in Fig. 2.

[0067] The second fixing unit (3) above is configured to attach a solar module (P) and is fitted into the first fixing unit (2). The second fixing units (3) are formed as a pair on both sides of the first fixing unit (2) and are fitted and seated on both sides of the first fixing unit (2), so that adjacent solar modules (P) are attached and connected to each other. The second fixing unit (3) is also coupled to the first fixing unit (2) in a way that it can be detached and attached by fitting, so that quick installation, maintenance and management are possible, and it is coupled to both sides of one first fixing unit (2) so that attachment and connection of the solar module (P) can be easily achieved. A pair of second fixing units (3) are fitted onto the first fixing unit (2) from both sides, and are connected to each other in the fitted state to be fixed to the first fixing unit (2), so that the solar modules (P) adjacent to each second fixing unit (3) are respectively attached. For this purpose, the second fixing unit (3) may include a fixing member (31), a connecting means (32), and an attachment means (33).

[0068] The above-mentioned fixing member (31) is configured to be fitted into the first fixing unit (2), and a solar module (P) is attached to the upper side thereof to be coupled thereto. The above-mentioned fixing member (31) can maintain a state in which it is stably fitted onto the first fixing unit (2) by including a fitting portion (311) and a fixing portion (312), and can have an additional insulating function through the fixing portion (312).

[0069] The above fitting part (311) is configured to be inserted into and fitted into the above connecting part (212), and is fixed by being inserted into the insertion groove (212a) of the connecting part (212). To this end, the fitting part (311) may include a support member (311a) and an insertion projection (311b).

[0070] The above support member (311a) is configured to protrude inwardly by a certain length, such that the insertion projection (311b) protrudes downwardly and is fitted into the insertion groove (212a), and the support members (311a) of the second fixing units (3) on both sides can be connected and fixed upwardly by the connecting means (32).

[0071] The above insertion projection (311b) is configured to protrude downward from the support member (311a), and is fitted into and fixed in the insertion groove (212a). In particular, the insertion projection (311b) may include a protruding surface (311b-1) formed to protrude outwardly in a rounded manner at one point, and is formed in a position and shape corresponding to the fitting groove (212b) of the insertion groove (212a). Accordingly, when the insertion projection (311b) is fitted into the insertion groove (212a), the protruding surface (311b-1) is fitted closely into the fitting groove (212b), thereby preventing detachment and ensuring stable fixation.

[0072] The above-mentioned mounting portion (312) is configured to have a certain space inside the outer side of the support member (311a), and may be formed as a frame having a square cross-section. The mounting portion (312) is mounted on the unit body (21) outside the coupling portion (212), and a solar module (P) is attached to the upper side thereof by an attachment means (33). Therefore, the mounting portion (312) can maintain the solar module (P) in a stably attached state, and can have an additional heat blocking function through the inner space. In addition, the mounting portion (312) may include a recessed groove (312a) formed to be recessed in a round shape at one point on the inner side. The above-mentioned recess (312a) can be formed in a position and shape corresponding to the convex end (212c) of the unit body (21), and when the fixing portion (312) is fixed on the unit body (21), it is supported by being in close contact with the convex end (212c), thereby maintaining a more stable fixing state. In addition, the fixing portion (312) can form a fixing groove (312b) that is recessed into the bottom at a certain height so that the head portion of the fixing piece (23) can be inserted, and through this, even when the fixing piece (23) protrudes from the upper portion of the unit body (21), the fixing portion (312) can be fixed by being in close contact with the unit body (21).

[0073] The above connecting means (32) is configured to connect the second fixing units (3) on both sides fitted into the first fixing unit (2) and fix them to the first fixing unit (2), so that the second fixing units (3) on both sides can be connected and fixed at once, enabling rapid installation and ensuring stable fixing of the second fixing unit (3). To this end, the connecting means (32) may include a reinforcing clamp (321) and a fastening piece (322).

[0074] The above reinforcing clamp (321) is configured to connect the second fixing units (3) and is mounted on the support ends (311a) of the second fixing units (3) on both sides.

[0075] The above fastening piece (322) is configured to fasten the reinforcing clamp (321) to the first fixing unit (2), and is formed in the form of a screw, screw, etc., so that it can penetrate the reinforcing clamp (321) and be inserted into and fastened to the connecting portion (212) of the first fixing unit (2).

[0076] The above attachment means (33) is configured to attach a solar module (P) to a second fixing unit (3), and fixes the solar module (P) by attaching a Norton tape (331) between the second fixing unit (3) and the solar module (P), and while the Norton tape (331) is attached, fixing silicone (332) is applied to the outside of the Norton tape (331) and hardened to ensure complete fixation. Here, the Norton tape (331) is a high-strength double-sided tape in the form of foam, which can be formed of high-density polyurethane foam, and stably fixes the solar module (P) until the fixing silicone (332) is completely hardened.

[0077] The above closing means (4) is configured to seal between the solar modules (P) attached to the second fixing units (3), and seals between the solar modules (P) attached to the second fixing units (3) on both sides from the outside. The closing means (4) may first insert a backup material (41) in the form of Styrofoam or the like between the solar modules (P), and then apply external silicone (42) on the backup material (41) to form a sealed state. Here, weather silicone having weather resistance may be applied as the external silicone (42), and by supporting and sealing between the solar modules (P), it is possible to improve insulation and absorb vibrations.

[0078]

[0079] Referring to FIG. 4, a detachable functional building-integrated solar power generation system according to another embodiment of the present invention will be described. The detachable functional building-integrated solar power generation system includes an exterior wall structure (1), a first fixing unit (2), a second fixing unit (3), and a finishing means (4) similar to the first embodiment, except that the fitting projection (11) may include a catch (111), the unit body (21) may include a fixing groove (213), and the mounting portion (312) may additionally include a filler (312c) and an injection hole (312d). In addition, the Norton tape (331) may additionally include an injection groove (331a).

[0080] The above-mentioned hook (111) is formed to protrude outward from the upper end of the fitting projection (11), so that when the first fixing unit (2) is fitted into the fitting projection (11), the hook (111) passes through the fitting hole (221) and is fixed by being caught in the unit body (21). To this end, the unit body (21) of the first fixing unit (2) may have a fixing groove (213) formed at a certain height in the bottom thereof, and the hook (111) is inserted into and fixed in the fixing groove (213). At this time, the hook (111) may be fixed by being fixed by being caught in the upper side of the earthquake-resistant insulating rubber (22) by rotating the first fixing unit (2) while the hook (111) is inserted into the fixing groove (213) by passing through the fitting hole (221), thereby enabling more stable fitting of the first fixing unit (2).

[0081] In addition, the filler (312c) is configured to be injected and filled into the space within the mounting portion (312) of the second fixed unit (3), and a material such as silicone that can have a heat insulating function, a vibration absorbing function, etc. can be injected. Therefore, the filler (312c) can provide higher heat insulating properties than the heat insulating function through the empty space of the mounting portion (312), and can even add an earthquake-resistant function through vibration absorption. The filler (312c) can be injected into the mounting portion (312) through an injection hole (312d) formed on one side of the mounting portion (312), and the injection hole (312d) can be formed at the upper end of one side of the mounting portion (312) so that the filler (312c) can be completely filled within the mounting portion (312).

[0082] In addition, the Norton tape (331) may additionally include an insertion groove (331a) that is recessed to a certain depth from the outside where the fixing silicone (332) is applied, and the fixing silicone (332) may be injected and applied even within the insertion groove (331a). Accordingly, an insulating function and a vibration absorption function may be formed within the Norton tape (331) through the fixing silicone (332), and the fixing force by the Norton tape (331) may also be further enhanced.

[0083]

[0084] Referring to FIG. 5, a method for installing a detachable functional building-integrated solar power generation system according to the present invention may include a first unit fitting step (S1) of fitting a first fixing unit (2) to an exterior wall structure (1), a first unit fixing step (S2) of fixing the first fixing unit (2) fitted to the exterior wall structure (1), a second unit fitting step (S3) of fitting second fixing units (3) on both sides to the first fixing unit (2) fixed to the exterior wall structure (1), a connecting fixing step (S4) of connecting the second fixing units (3) on both sides fitted to the first fixing unit (2) and fixing them to the first fixing unit (2), a module attaching step (S5) of attaching a solar module (P) to each second fixing unit (3), and a finishing step (S6) of sealing between the attached solar modules (P).

[0085] The above first unit fitting step (S1) is a process of fitting the first fixing unit (2) to the outer wall structure (1), such that the fitting projection (11) of the outer wall structure (1) is inserted along the fitting hole (221) of the first fixing unit (2). At this time, if a catch (111) is formed in the fitting projection (11), the catch (111) can be rotated and fixed while passing through the fitting hole (221) and being inserted into the fixing groove (213) of the unit body (21).

[0086] The above first unit fixing step (S2) is a process of fixing the first fixing unit (2) fitted into the exterior wall structure (1) to the exterior wall structure (1), and the fixing piece (23) can be inserted so as to penetrate the unit body (21) and the earthquake-resistant insulating rubber (22) and be fixed to the exterior wall structure (1). Accordingly, since the fixing is performed while the first fixing unit (2) is fitted into the exterior wall structure (1), the first fixing unit (2) can be easily installed at an accurate location, and even during maintenance, the fixing piece (23) can be released so that the first fixing unit (2) can be easily separated.

[0088] The above-described connecting and fixing step (S4) is a process of connecting the second fixing units (3) on both sides fitted into the first fixing unit (2) while simultaneously fixing them to the first fixing unit (2). In this process, the reinforcing clamp (321) is seated between the support ends on both sides, and the fastening piece (322) is inserted and fixed into the connecting portion (212) of the first fixing unit (2) by passing through the reinforcing clamp (321). Therefore, the above-described connecting and fixing step (S4) can simultaneously connect the second fixing units (3) on both sides while fixing them to the first fixing unit (2), thereby enabling rapid installation and ensuring that the second fixing unit (3) is firmly fixed to the first fixing unit (2).

[0089] The above module attachment step (S5) is a process of attaching a solar module (P) to each of the second fixing units (3). First, a Norton tape (331) is attached to the second fixing unit (3) to attach the solar module (P), and then fixing silicone (332) is applied to the outside of the Norton tape (331) and hardened to complete the attachment of the solar module (P).

[0090] The above finishing step (S6) is a process of sealing the space between the solar modules (P) attached to the second fixed unit (3). After inserting a backup agent (41) between the solar modules (P), external silicone (42) is applied to block the inflow of external substances and the movement of heat, and to enable vibration absorption between the solar modules (P).
