Abstract
Description
Technology Field
[0001] The present invention relates to a curtain wall frame structure for heterogeneous panels that allows exterior panels to be freely installed regardless of thickness and enables easy detachment and maintenance when using solar panels, wherein a first panel installed on one side of a vertical frame is supported on the back surface of the front plate of a first finishing cap fixed to the front surface of the vertical frame, and a second panel installed on the other side of the vertical frame is supported on the back surface of the flat portion of a second finishing cap detachably coupled to the front plate of the first finishing cap. Background Technology
[0003] Thermal power generation, which primarily utilizes fossil fuels, poses serious environmental pollution problems due to exhaust gases. Furthermore, nuclear power generation incurs high costs for nuclear waste disposal, and the scale of damage in the event of a power plant accident is very large.
[0004] Consequently, as interest and demand for renewable energy increase worldwide, technologies related to power generation using solar power are steadily growing.
[0005] For example, there is a growing trend of installing solar power generation systems in apartment buildings to utilize them for common electricity.
[0006] To address this, solar panels were frequently installed on building rooftops in the past. However, since the rooftops of multi-unit residential buildings have a relatively smaller surface area compared to exterior walls, there are limitations to electricity production.
[0007] Therefore, the application of solar power generation that actively utilizes building exterior walls or windows has been increasing recently. In this case, the installation area of solar panels can be maximized to improve the building's energy efficiency, and since solar power generation is possible without compromising the building's aesthetics, it is advantageous for renewable energy production in urban areas.
[0008] In particular, recently, the construction of curtain walls is increasing not only in general buildings but also in multi-unit housing, and the curtain wall system is advantageous for the application of solar panels because the panel sizes can be standardized and attached (Published Patent No. 10-2020-0005766).
[0009] Solar panels used on buildings, namely PV (Photo Voltaic) panels, include BIPV (Building Integrated Photo Voltaic) panels and BAPV (Building Attached Photo Voltaic) panels.
[0010] BIPV panels utilize the building-integrated photovoltaic module itself as an exterior building material, whereas BAPV panels are building-attached photovoltaic panels that are installed on the exterior walls of a building.
[0011] BIPV panels are formed by bonding glass or metal plates to both sides of a PV module, and they are thin and very expensive compared to BAPV panels. BAPV panels are more economical than BIPV panels because they are cheaper, but they are thick because they are constructed by laminating an EVA sheet and a back sheet on the back of a PV module and attaching an aluminum frame to the side.
[0012] Meanwhile, because solar panels require continuous maintenance and replacement due to their lifespan, they must be fixed to the curtain wall frame as a detachable unit, unlike the glass panels typically used in curtain walls.
[0013] FIG. 1 is a curtain wall system with existing glass panels installed, in which glass panels (200) are installed on both sides by attaching a T-shaped end cap (300) to the front of a vertical frame (100).
[0014] Registered Patent No. 10-1482164 enables the installation of glass panels or solar panels by inserting them between module brackets, which are horizontal frames (transoms). In this case, a first module bracket is installed at the top and bottom of the glass panel, and for the solar panel, one end is supported by the first module bracket, and a second module bracket is installed at the other end to detachably connect the panel.
[0015] The above technology has the disadvantage that the design and installation of the curtain wall are complex and cumbersome because different types of module brackets must be installed depending on the type of panel.
[0016] Furthermore, since glass panels or solar panels are installed and supported on the front of horizontal or vertical frames, only BIPV panels, which are thinner than glass panels, can be used when installing a combination of glass and PV panels; conversely, the application of thicker BIPV panels is difficult, leading to a problem of significantly increased construction costs. The problem to be solved
[0018] To solve the above-mentioned problems, the present invention aims to provide a curtain wall frame structure for heterogeneous panels that allows exterior panels, such as glass panels or BAPV panels, to be freely installed regardless of their thickness, and enables easy detachment and maintenance when using solar panels. means of solving the problem
[0020] The present invention, according to a preferred embodiment, provides a curtain wall frame structure for heterogeneous panels, characterized by comprising: a vertical frame provided in a vertical direction; a first end cap comprising a back plate fixed to the front of the vertical frame, a front plate provided in front of the back plate so as to be spaced parallel to the back plate to support the front end of a first panel, and a side plate connecting one end of the front plate and the back plate; and a second end cap comprising a flat plate portion that is detachably coupled to the front of the front plate of the first end cap and extends outwardly to the side plate of the first end cap to support the front end of a second panel.
[0021] According to another preferred embodiment, the present invention provides a curtain wall frame structure for heterogeneous panels, characterized in that a fastening groove is formed at the corner portion where the front plate and the side plate of the first end cap meet, and a fastening hook is formed protrudingly at the center of the rear surface of the flat portion of the second end cap, which is inserted into and hooked into the fastening groove.
[0022] According to another preferred embodiment, the present invention provides a curtain wall frame structure for heterogeneous panels, characterized in that the flat portion of the second end cap is spaced apart from the front plate of the first end cap, and a supporting protrusion is formed protrudingly on the rear surface of the first panel side of the flat portion, which is supported on the front surface of the front plate of the first end cap.
[0023] According to another preferred embodiment, the present invention provides a curtain wall frame structure for heterogeneous panels, characterized in that a spacing portion is formed at the second panel side end of the flat plate portion, which is bent in an L-shape toward the inside.
[0024] According to another preferred embodiment, the present invention provides a curtain wall frame structure for heterogeneous panels, characterized in that a fixing bracket is coupled to the side of the second panel of the vertical frame, the fixing bracket comprising a fixing plate fixed to the side of the vertical frame and a supporting plate protruding outwardly in an orthogonal direction from the front end of the fixing plate, so that the second panel is received and supported between the supporting plate of the fixing bracket and a second finishing cap. Effects of the invention
[0026] According to the present invention, the following effects are achieved.
[0027] First, the first panel installed on one side of the vertical frame is supported on the back surface of the front plate of the first finishing cap fixed to the front of the vertical frame, and the second panel installed on the other side of the vertical frame is supported on the back surface of the flat portion of the second finishing cap detachably coupled to the front plate of the first finishing cap. Therefore, exterior panels, such as glass panels or BAPV panels installed on both sides of the vertical frame, can be easily detached from the curtain wall frame.
[0028] Second, when a fixing bracket is attached to the side of the second panel of the vertical frame, the second panel can be installed between the support plate of the fixing bracket and the flat portion of the second end cap regardless of the thickness of the second panel by adjusting the front and rear positions of the fixing bracket according to the thickness of the second panel.

FIG. 5 is a cross-sectional view illustrating the curtain wall frame structure for heterogeneous panels of the present invention, and FIG. 6 is a perspective view illustrating the state in which a gasket is coupled to the first end cap.
[0034] As illustrated in FIGS. 2 to 6, etc., the curtain wall frame structure for heterogeneous panels according to the present invention is characterized by being composed of: a vertical frame (1) provided in a vertical direction; a first end cap (3) comprising a back plate (31) fixed to the front of the vertical frame (1), a front plate (32) provided in front of the back plate (31) so as to be spaced parallel to the back plate (31) and supporting the front end of the first panel (2a), and a side plate (33) connecting one end of the front plate (32) and the back plate (31); and a second end cap (4) comprising a flat plate portion (41) that is detachably coupled to the front of the front plate (32) of the first end cap (3) and extends outward from the side plate (33) of the first end cap (3) to support the front end of the second panel (2b).
[0035] The present invention is intended to provide a curtain wall frame structure for heterogeneous panels that allows exterior panels to be freely installed regardless of their thickness, such as glass panels or BAPV panels, and enables easy detachment and maintenance when using solar panels.
[0036] The present invention is for combining various exterior panels, such as glass panels or PV panels, with a curtain wall and comprises a vertical frame (1), a first end cap (3), and a second end cap (4).
[0037] The above vertical frame (1) forms a mullion of the curtain wall frame and is installed vertically on the front of the building.
[0038] The above vertical frame (1) may be provided in multiple numbers spaced apart from each other in the width direction.
[0039] A horizontal frame (not shown) forming a transom of a curtain wall frame is installed between adjacent vertical frames (1).
[0040] The above vertical frame (1) can be formed with a square or rectangular cross-section.
[0041] A first panel (2a) is installed on one side based on the above vertical frame (1), and a second panel (2b) is installed on the other side.
[0042] A first end cap (3) for supporting the end of the first panel (2a) is attached to the front of the vertical frame (1).
[0043] The first end cap (3) is composed of a back plate (31) and a front plate (32) spaced apart from each other and a side plate (33) connecting one end of them, and is formed with a U-shaped cross section with one side open.
[0044] The back plate (31) of the first end cap (3) is fixed to the front of the vertical frame (1).
[0045] The above back plate (31) can be attached to the front of the vertical frame (1) with a fastening bolt (B).
[0046] The above front plate (32) is provided in front of the back plate (31) and spaced apart parallel to the back plate (31).
[0047] One end of the first panel (2a) is received and supported between the front of the vertical frame (1) and the back of the front plate (32).
[0048] To this end, it is preferable that the front plate (32) be formed longer than the back plate (31).
[0049] A connecting protrusion (34) may be formed protruding from the outer end of the above-mentioned back plate (31) to connect a gasket (6) that is in close contact with and supported on the back end of the first panel (2a) (Figs. 5, 6).
[0050] The above gasket (6) may be an EPDM compression gasket.
[0051] A sealant (7) can be applied between the front plate (32) and the front end of the first panel (2a).
[0052] A backup material (71) for sealant application may be installed on the inner side of the sealant (7).
[0053] On the back surface of the front plate (32), a support protrusion (35) may be formed so as not to push the backup material (71) inward.
[0054] The second end cap (4) is provided on the front of the front plate (32) of the first end cap (3).
[0055] The above second end cap (4) is configured to include a flat plate (41).
[0056] The flat plate portion (41) of the second end cap (4) is provided parallel to the front plate (32) of the first end cap (3) and can be configured to cover the entire front plate (32). However, the end portion of the flat plate portion (41) on the side of the second panel (2b) is formed to extend outward from the side plate (33) of the first end cap (3), so that the end portion of the second panel (2b) is received and supported in the space on the back.
[0057] The second end cap (4) is detachably coupled to the front plate (32) of the first end cap (3).
[0058] Accordingly, if the second panel (2b) is a PV panel, the second panel (2b) can be removed from the curtain wall frame after separating the second end cap (4) from the first end cap (3) as needed.
[0060] FIG. 7 is a perspective view illustrating the connection relationship between the first end cap and the second end cap.
[0061] As shown in FIGS. 5 and 7, a fastening groove (36) is formed at the corner where the front plate (32) and the side plate (33) of the first end cap (3) meet, and a fastening hook (42) that is inserted into and hooked inside the fastening groove (36) may be formed protrudingly at the center of the back surface of the flat plate portion (41) of the second end cap (4).
[0062] The second end cap (4) can be fastened to the first end cap (3) with a fastening bolt. However, in this case, fastening takes a long time and there is a problem that the fastening bolt is exposed to the front of the second end cap (4).
[0063] Accordingly, in order to allow the second end cap (4) to be attached to the front of the first end cap (3) with a single touch, a fastening groove (36) may be formed in the first end cap (3), and a fastening hook (42) may be formed in the second end cap (4).
[0064] The flat portion (41) of the second end cap (4) extends toward the second panel (2b) rather than the first end cap (3) and is joined to form an approximate T-shape together with the side plate (33) of the first end cap (3). Therefore, it is preferable to form the fastening hook (42) at a position corresponding to the side plate (33) at the center of the back of the flat portion (41) so that the second end cap (4) can maintain balance.
[0065] Accordingly, the fastening groove (36) to which the fastening hook (42) is attached can be formed at the corner where the side plate (33) and the front plate (32) meet.
[0066] The above-mentioned fastening groove (36) may be formed to be open toward the second panel (2b), and a locking projection (361) may be formed protrudingly on the inner side entrance side of the front side.
[0067] The above-mentioned fastening hook (42) may be formed in a flat L-shape, and a locking projection (421) may be formed on the end that is inserted into the fastening groove (36).
[0068] The locking projection (421) of the above-mentioned locking hook (42) is configured to engage with and lock into the locking projection (361) inside the locking groove (36).
[0069] It is preferable that the locking projections (361, 421) have an inclined surface on their front edge so that the locking projection (421) of the locking hook (42) can enter the locking groove (36) by sliding the second end cap (4) from the side.
[0071] As illustrated in FIGS. 5 and 7, the flat plate portion (41) of the second end cap (4) is spaced apart from the front plate (32) of the first end cap (3), and a supporting protrusion (43) that is supported on the front of the front plate (32) of the first end cap (3) may be formed protrudingly on the rear side of the first panel (2a) of the flat plate portion (41).
[0072] The flat plate portion (41) of the second end cap (4) can be configured to be in close contact with the front plate (32) of the first end cap (3).
[0073] However, in this case, since it may be difficult to remove the second end cap (4) from the first end cap (3), it is preferable to configure the flat portion (41) of the second end cap (4) to be spaced apart from the front plate (32) of the first end cap (3).
[0074] At this time, a supporting protrusion (43) may be formed protruding from the back surface of the flat plate (41) so that the second end cap (4), which is connected to the fastening groove (36) of the first end cap (3) with the fastening hook (42) of the central part separated from the first end cap (3), can be fastened while maintaining parallelism without tilting.
[0075] The above-mentioned support protrusion (43) is formed protruding from the back surface of the flat plate portion (41) at the front plate (32) side of the first end cap (3), that is, at the first panel (2a) side, so that its end can be supported on the front surface of the front plate (32).
[0077] As shown in FIGS. 5 and 7, a spacing portion (44) that is bent in an L-shape toward the inside may be formed at the end of the second panel (2b) of the flat plate portion (41).
[0078] When the above-mentioned flat plate (41) is joined so as to be spaced apart from the front plate (32), if the second panel (2b) is installed directly on the back surface of the flat plate (41), the front surface of the second panel (2b) is positioned further forward than the front surface of the first panel (2a), thereby forming a step difference and potentially damaging the appearance.
[0079] Accordingly, a spacing portion (44) may be provided at one end of the flat portion (41) of the second end cap (4) so that the front surfaces of the first panel (2a) and the second panel (2b) can form the same surface.
[0080] The above spacing member (44) is formed to protrude inward from the end of the second panel (2b) of the flat plate member (41) so as to support the front surface of the second panel (2b) to be the same as the front surface of the first panel (2a).
[0081] In order to install a backup material (71) and a sealant (7) between the above spacing member (44) and the second panel (2b), the spacing member (44) may be formed with an L-shaped cross-section in which the end is vertically bent inward.
[0083] FIG. 8 is a cross-sectional view illustrating an embodiment in which the thickness of the first panel and the second panel are the same, FIG. 9 is a cross-sectional view illustrating an embodiment in which the first panel is a finishing cap, and FIG. 10 is a perspective view illustrating a fixing bracket equipped with a gasket fixing device.
[0084] As illustrated in FIGS. 5, 8 to 10, a fixing bracket (5) is coupled to the side of the second panel (2b) of the vertical frame (1), the fixing bracket (5) being composed of a fixing plate (51) fixed to the side of the vertical frame (1) and a supporting plate (52) protruding outwardly in an orthogonal direction from the front end of the fixing plate (51), so that the second panel (2b) can be received and supported between the supporting plate (52) of the fixing bracket (5) and the second end cap (4).
[0085] The front surface of the second panel (2b) is supported by the second end cap (4).
[0086] At this time, the back surface of the second panel (2b) can be supported on the front surface of the vertical frame (1) just like the first panel (2a). However, in this case, if the second panel (2b) is thicker than the first panel (2a), it is difficult to install the second panel (2b).
[0087] Accordingly, a fixing bracket (5) can be installed on the side of the vertical frame (1) so that the second panel (2b) can be installed and supported regardless of thickness.
[0088] The above-mentioned fixed bracket (5) is an angle member composed of a fixed plate (51) and a support plate (52).
[0089] The above fixing plate (51) can be fixed to the side of the second panel (2b) of the vertical frame (1) with a fastening bolt (B), etc.
[0090] The above support plate (52) is provided in an outward vertical direction at the front end of the fixing plate (51), and the back surface of the second panel (2b) is supported in front.
[0091] That is, the back surface of the first panel (2a) is supported on the front surface of the vertical frame (1), whereas the back surface of the second panel (2b) can be supported on the fixing bracket (5) on the side of the vertical frame (1).
[0092] The above fixing bracket (5) can be fixed to the side of the vertical frame (1) by adjusting the front and rear position according to the thickness of the second panel (2b).
[0093] For example, if the first panel (2a) is a glass panel and the second panel (2b) is a BAPV panel with a thickness greater than that of the glass panel, the fixing bracket (5) can be fixed at a mid-side position of the vertical frame (1) so that the front of the support plate (52) is positioned inwardly at a stepped position compared to the front of the vertical frame (1) (Fig. 5).
[0094] In addition, if the second panel (2b) is a glass panel or a BIPV panel and has the same thickness as the first panel (2a), the fixing bracket (5) can be fixed to the front side of the vertical frame (1) so that the front surface of the support plate (52) forms the same surface as the front surface of the vertical frame (1) (Fig. 8).
[0095] The first panel (2a) or second panel (2b) may be a glass panel or a BAPV panel, as well as an end cap (Fig. 9).
[0096] By supporting the second panel (2b) with the above-mentioned fixed bracket (5), the width of the vertical frame (1) can be formed to be thin and slender.
[0097] Meanwhile, a gasket fixing device (8) for fixing a gasket (6) may be provided on the front surface of the support plate (52) of the above-mentioned fixing bracket (5).
[0098] The above gasket fixing device (8) can be fixed to the support plate (52) with a fastening bolt (B) (Fig. 10). Explanation of the symbols
