'It is a schematic cross-sectional configuration diagram of the line. As disclosed in the drawings, the present invention is characterized by including a support plate 10 , a frame, a heat insulating material 30 , and a solar panel 40 . Hereinafter, each of these configurations will be described.

It is assumed that the support plate according to the present invention is made of a metal plate, but is not limited thereto, and may be made of a synthetic resin plate having a certain hardness depending on the construction environment, wood, a gypsum board, or a composite plate of various materials.

In addition, a plurality of through-holes may be formed in the support plate, and unlike the drawings disclosed as a flat plate, a specific portion may be bent or a plurality of bent portions may be formed, and furthermore, the support plate may have a structure in which a central portion is penetrated. The size and shape of the through hole may be variously changed for building structure, exterior design, sound absorption, etc., and the bent part may also be variously changed and applied for exterior design or rigidity reinforcement.

At this time, the present invention proposes a case in which the reinforcement strips 112 and 116 are provided along the lower edge of the support plate 10 as shown in FIG. 5 . In the present invention, the support plate 10 is a means for supporting each component and a part directly coupled to the building. When separate reinforcement strips 112 and 116 are provided on the lower edge of the support plate 10, the support plate 10 ) can support the present invention more stably, as well as enhance the binding force with the building.

In the drawings, a case is disclosed in which the reinforcing strip is made of a vertical reinforcing strip 112 provided on each left and right of the lower surface of the support plate 10 and a horizontal reinforcing strip 116 provided on each of the upper and lower surfaces of the lower surface of the support plate 10, but in the circumstances Accordingly, any one of the vertical reinforcement strip 112 or the horizontal reinforcement strip 116 may be provided. The reinforcing strip may be made of metal, synthetic resin, or a composite material.

The frame is a part on which the photovoltaic panel 40 is mounted, and forms an internal accommodating space of a certain size in the unit photovoltaic module together with the support plate 10, and is combined with the frame of another adjacent photovoltaic module. part to be In the present invention, the frame may be composed of the first, second, and third frames 22, 24, 26.

The first frame 22 is installed in each corner portion of the support plate 10, each lower portion is coupled to the support plate 10, and each upper portion extends to a certain vertical height. A separate first auxiliary frame as indicated by reference numeral 23 in FIG. 7 may be further provided between the first frames.

In this case, the first frame 22 may be separated into a first lower frame 226 and a first upper frame 222 as shown in FIG. 8 . In this case, the lower end of the first lower frame 226 is coupled to the support plate 10 , and the upper end thereof extends to a predetermined vertical height. The lower end of the first upper frame 222 is coupled to the upper end of the first lower frame 226 , and the upper end thereof extends to a predetermined vertical height.

The first lower frame 226 and the first upper frame 222 are interposed between the fitting end formed at the upper end of the first lower frame 226 and the fitting formed at the lower end of the first upper frame 222 as shown in the drawing. It may be connected by a combination of grooves. However, it should be noted that this is only an example of various various coupling methods.

The second frame 24 is positioned to have a predetermined vertical height from each of the front and rear ends of the support plate 10 , and both end portions are connected to each of the upper portions of the first frame 22 opposite to each other. Accordingly, the first frame 22 opposite to each other in each of the front end portion and the rear end portion of the support plate 10 is integrated.

The third frame 26 is positioned with a predetermined vertical height from each of the left and right ends of the support plate 10, and both ends are connected to each of the upper ends of the first frame 22 opposite to each other. . Accordingly, all of the first, second, and third frames 22, 24, and 26 form an integrated structure.

It is preferable to determine the width and length of each of the first, second, and third frames in consideration of the size of the solar panel or the thickness of the insulating material, rather than uniformly determining it. In addition, of course, the shape, structure, material, etc. of each of the first, second, and third frames may be variously changed according to circumstances.

In this case, the present invention does not exclude the case where the lower portion of each of the first frames is connected by each of the separate fourth and fifth frames. That is, as shown in FIG. 6 , the fourth frame 23 is positioned at the front end and the rear end of the support plate 10 , respectively, and both ends of each fourth frame 23 are the front end and the rear end of the support plate 10 . It is connected to the lower portion of each of the first frame 22 that is installed to face each other in each.

And, the fifth frame 27 is located at each of the left end portion and the right end portion of the support plate 10 , and both ends of each fifth frame 27 are the left end portion and the right end portion of the support plate 10 , respectively. It is connected to the lower portion of each of the first frame 22 that is installed to face each other.

In this case, the first frame 22 connected to the second and third frames 24 and 26 and forming an integral structure can be supported by each of the fourth and fifth frames 23 and 27, the first, The sense of unity between the 2 and 3 frames 22 , 24 and 26 can be more firmly maintained. The lower surface of each of the fourth and fifth frames may be combined with the support plate.

6 discloses a configuration in which each of the fourth and fifth frames are provided and connected at the same time, but the present invention does not exclude a case in which only one of the fourth and fifth frames is installed depending on circumstances such as the size of the solar panel. The width or thickness of each of the fourth and fifth frames may vary depending on the size of the solar panel or the thickness of the insulating material.

In addition, the present invention proposes a case in which the coupling portion is formed in the upper portion of each of the second and third frames. First, a first coupling portion is formed on an outer surface portion of the second frame located at the front end portion of the support plate among the second frames, and a second coupling portion is formed on the outer surface portion of the second frame located at the rear end portion of the support plate among the second frames. An addition may be formed.

And, a third coupling part is formed on the outer surface of the third frame positioned at the left end of the support plate among the third frames, and the third coupling part is formed on the outer surface of the third frame positioned at the right end of the support plate among the third frames. 4 A coupling portion may be formed.

At this time, the first and second coupling parts are in close contact with each other, and the third and fourth coupling parts are in close contact with each other. In FIG. 3 , an example of the first and second coupling portions 242 and 243 formed in the second frame 24 and an example of the third and fourth coupling portions 262 and 263 formed in the third frame 26 are shown. has been disclosed.

Each of these coupling parts can be changed and applied in various structures, and in consideration of the convenience and constructability of the coupling, it is preferable to have an alternating structure. Although the present invention assumes a case in which the coupling portion is formed in each of the second and third frames, the coupling portion having an alternating structure may be formed in any one of the second and third frames depending on circumstances.

In addition, in the present invention, the frame may have a structure having a rectangular rim with an open central portion, unlike the above-described configuration. In this case, the frame of the frame structure is placed on each of the front end and the rear end of the support plate, or on each of the left and right ends of the support plate, and then, as a frame of a rod structure having a certain length, the opposite frame frames are connected to each other. will be able

The lower surface of the insulating material 30 is in close contact with the upper surface of the support plate 10 , and the side portions thereof are exposed to the outside through the space between the first frames 22 opposite to each other as shown in FIG. 1 . The insulating material is sufficient as long as it is a material used as an insulating material in the related industry.

The reason that the present invention exposes the side portion of the insulator to the outside is that when constructed on site, it is embedded in an adjacent photovoltaic module so that the side portions of the insulators facing each other are in close contact with each other, so that there is a discontinuity between the adjacent insulators. This is to block the heat transfer itself to the outside by not having a surface.

At this time, the present invention does not exclude the case in which the concave-convex surface of any shape is formed on the side surface of the heat insulating material. It goes without saying that the concavo-convex surface formed of the insulating material is not limited to a specific shape and may be variously changed. When the concave-convex surface is formed on the side portion of the insulator, it is possible to further enhance the insulation effect in that the side surfaces of the adjacent insulators can be more closely adhered to each other during the construction process of the photovoltaic module.

In the case of forming the uneven surface of any shape on the side surface of the insulating material, each of the front and rear side surfaces of the insulating material among the uneven surfaces is formed in an alternating structure, and each of the left and right surfaces among the uneven surfaces is formed in an alternating structure. desirable. This is because each of the front side and the rear side, and the left side and the rear side, respectively contact the adjacent insulator during the construction process of the photovoltaic module.

9, an example of the 1st, 2nd, 3rd, and 4 uneven|corrugated surfaces 32, 34, 36, 38 formed in the heat insulating material 30 is disclosed. That is, the first concave-convex surface 32 formed on the front side of the insulator 30 is in close contact with the second concave-convex surface 34 formed on the rear side of the insulator 30 during the construction process, and the left side of the insulator 30 . The third concave-convex surface 36 formed on the surface is in close contact with the fourth concave-convex surface 38 formed on the right side of the insulator 30 during the construction process.

In forming the concave-convex surface on the side part of the insulating material, if the front and rear side surfaces and the left and right side surfaces at the opposite positions are made into an alternating structure, the workability in the field can be improved. Not only that, but the adhesion between adjacent insulating materials can also be improved to a significant level.

On the other hand, the lower surface of the insulation material is placed in close contact with the upper surface portion of the support plate, and when constructed in this state, the adhesion between the insulation material and the support plate is reduced, and the insulation material may be separated from the support plate. To this end, the present invention proposes a case in which a pressure strip is provided on the upper surface of the insulating material.

As illustrated in FIG. 10 , the pressure strip presses the heat insulator 30 in the direction of the support plate 10 in a state located on the upper surface of the heat insulator 30 to enhance the adhesion between the heat insulator 30 and the support plate 10 . The pressure strip may be made of a synthetic resin or metal having a certain width and a certain length.

Although the drawing shows a case in which the pressure strip is composed of a vertical pressure strip 312 and a horizontal pressure strip 316 that are orthogonal to each other, the present invention is made of only a plurality of vertical pressure strips or a plurality of horizontal pressure strips, or diagonally The case of having an X-shaped structure is not excluded. Reference numeral 314 denotes a fastening means for integrating the pressure strip with each of the support plate and the heat insulating material.

In addition, as described above, when the first frame is separated into the first lower frame and the first upper frame, the present invention provides that the first lower frame is formed by varying the vertical height corresponding to the thickness of the insulating material placed on the support plate. do not exclude

That is, as shown in FIG. 8, when the first frame is configured to be separated into the first lower frame 226 and the first upper frame 222, the first upper frame 222 maintains a constant vertical height h, and 2 The lower frame 226 is configured to have different heights, such as h1, h2, h3, etc. depending on the thickness of the insulating material placed on the support plate.

When the heat insulating material and the photovoltaic panel have an integrated structure, an air flow space is required between the photovoltaic panel and the heat insulator to remove heat generated during the operation of the photovoltaic panel, and the heat insulating material is the material or the unit solar according to the present invention. The required thickness may vary depending on the installation location (latitude) of the photovoltaic module.

Therefore, by making the first upper frame to have a certain vertical height, an air flow space is secured to efficiently remove heat generated during the operation of the solar panel, and the thickness of the first lower frame is determined according to the material or installation location. By preparing to correspond to a different insulator, it becomes possible to more conveniently perform the assembly operation of the unit photovoltaic module according to the demand.

The solar panel is a part that generates electricity using incident sunlight, and the lower part is spaced apart from the upper part of the insulator by a predetermined distance, and the edge part is coupled to the upper part of each of the second and third frames. Accordingly, as shown in FIG. 4 , a space of a certain size in which external air freely flows is formed between the lower surface portion of the solar panel 40 and the upper surface portion of the insulator 30 .

In the present invention, the photovoltaic panel is characterized in that it is made of a pure photovoltaic panel without a border frame to finish the edge of the conventional photovoltaic panel. That is, as shown in FIG. 2 , the present invention provides that each of the second and third frames 24 and 26 can simultaneously perform a finishing function such as an edge frame made of a metal material in a conventional solar panel. It is possible to significantly increase the economical efficiency of the photovoltaic module, as well as light weight and transportability.

In Figure 3, reference numerals 241 and 261, respectively, the second and third frames (24, 26), respectively, is formed in the upper portion of the solar panel 40 is a seating end. Coupling between the solar panel and the second and third frames may be made in various ways. In this case, a separate sealing material may be added to prevent water leakage through the edge portion of the solar panel and the second and third frames.

On the other hand, when the solar panel increases, its weight also increases proportionally. For this purpose, as shown in FIG. 7 , at least one first auxiliary frame 23 includes a third frame 26 and a support plate 10 . ) is not excluded, and also does not exclude the case where at least one support frame 25 is provided to support the solar panel 40 .

That is, the first auxiliary frame 23 is provided in the middle portion of the third frame 26 extending to a certain length to distribute some of the load acting on the third frame 26, and is supported on the lower surface of the solar panel 40 The frame 25 is provided to prevent the central portion of the solar panel 40 from sagging due to snow or strong wind.

In the drawings, only the case in which the first auxiliary frame 23 is provided between the third frames 26 is disclosed, but in the present invention, the first auxiliary frame 23 includes the third frame 26 as well as the second frame 24 . ) is not excluded. The material or configuration of the first auxiliary frame may be substantially the same as that of the first frame. Reference numeral 231 denotes a second auxiliary frame supporting the central portion of the support frame 25 , and may be provided while penetrating the central portion of the insulating material 30 .

In the unit photovoltaic module according to the present invention, the support plate (or the support plate and the reinforcement strip) is directly coupled to the outer or upper part of the building to constitute the roof or wall of the building. At this time, the support plate may be coupled to a wall surface, such as a support bar or board, such as an I-beam steel installed in a building by using a separate fastening bolt, etc. The present invention separately proposes the coupling method disclosed in FIG. 11 in addition to the conventional coupling method do.

That is, at least one first fastening hole 241, 261 is formed on the outer portion of each of the second and third frames 24 and 26 or on the outer portion of any one of the second and third frames 24 and 26, A second fastening hole 101 is formed in the support plate 10 positioned opposite to the first fastening holes 241 and 261, and then the support plate 10 as a separate fastening bolt 102 is attached to the outside of the building, not shown. That's what joins the upper part.

This combination method not only makes it possible to conveniently perform the assembly work in a building in that it does not interfere at all with the unit photovoltaic module installed adjacent to it, but also checks or inspects a specific unit photovoltaic module after construction is completed. When replacement is necessary, it is possible to very easily separate only the relevant unit photovoltaic module from the building.

Reference numerals 243 and 263 denote a cover, respectively. When the covers 243 and 263 are forcibly fitted and coupled to the grooves 242 and 262 formed in the upper portions of the first fastening holes 241 and 261, the first fastening of the second and third frames 24 and 26 is performed. The balls 241 and 261 are completely sealed from the outside. Although the drawings disclose a case in which the first fastening hole has a semicircular structure, the present invention does not exclude a case in which the first fastening hole is formed in a circular structure inside each of the second and third frames.

If the reinforcing strips 112 and 116 are provided on the lower surface of the support plate 10 as shown in FIG. 5, a separate fastening hole corresponding to each of the second fastening holes 101 must be formed in each of the reinforcing strips 112 and 116. is self-evident In this case, the fastening bolt 102 is coupled to the building by sequentially passing through the fastening holes (not shown) formed in each of the second fastening holes 101 and the reinforcing strips 112 and 116 of the support plate 10 .

On the other hand, when a plurality of unit photovoltaic modules according to the present invention are constructed in a building, the possibility of leakage through the coupling portion between the adjacent second and third frames cannot be completely excluded. To this end, the present invention proposes the following method.

First, as shown in Fig. 12a, a protruding end 264 having a predetermined height is formed on the outer upper surface of each of the third frames 26 to extend in the longitudinal direction, and as shown in Fig. 12b (including the schematic cross-sectional configuration of the BB' line) When installing the unit photovoltaic module adjacent to each other, each of the protruding end 264 of the third frame 26 on one side and the protruding end 264 of the second frame 26 on the other side opposite to each other is attached to the closing strip 27. method of joining by

The finishing strip 27 is preferably made of a length capable of combining at least one or more unit photovoltaic modules adjacent to the left and right. In this case, it is possible to fundamentally prevent leakage through the space between the adjacent third frames. Although not disclosed in the drawings, of course, a case in which a coupling portion is formed in the third frame as shown in FIG. 3 is not excluded.

The configuration shown in each of FIGS. 12A and 12B may be directly applied to the embodiment shown in FIG. 11 . That is, after forming the protruding end 264 in the second frame 26 , the first and second fastening holes 241 and 261 and the second fastening holes are formed in the second and third frames 24 and 26 and the support plate 10 , respectively. (101) is formed, and after coupling the support plate 10 to the building as the fastening bolts 102, each of the protruding ends 264 of the opposite second frame 26 are coupled to each other with the closing strip 27.

Next, as shown in FIG. 13a, one side portion is opened on the lower surface of the third frame 26 located at the right end portion of the support plate, and a first drain portion 268 protruding convexly downward is formed extending in the longitudinal direction, , on the lower surface of the third frame 26 located at the left end of the support plate, the second draining part 267 protruding downward is extended in the longitudinal direction.

In this case, when the unit photovoltaic module is installed adjacently as shown in FIG. 13b (including the schematic cross-sectional configuration of the line CC′), the second draining part 267 of the third frame 26 opposite to each other and adjacent to each other The end portion is inserted into the inner space of the first drain 268 of the third frame 26 on the other side. It goes without saying that the specific shapes of the first and second drainage units 267 and 268 may be changed.

At this time, when the protruding ends 264 of each of the third frames 26 facing each other are closed with the closing strips 27, unlike the above-described example, even if some leakage occurs through the space between the adjacent third frames, the first , it is possible to discharge to the outside of the building through the combined structure of the 2 draining part, so water leakage into the inside of the building does not occur. In addition, the unit photovoltaic module can form an integrated structure with each other by the finishing frame.

In the same manner as in the above-described example, in this embodiment, a case in which a coupling portion is formed in each of the third frames as shown in FIG. 3 is not excluded. On the other hand, although only the case for the third frame in the unit photovoltaic module is disclosed in the accompanying drawings, the present invention is that each of these protruding ends or drains, and the combined configuration of the finishing strip is applied to the second frame as it is. Of course, this is not excluded.

A schematic construction method of the present invention having such a configuration will be described with reference to the above description and attached FIG. 14 .

First, a plurality of unit photovoltaic modules are prepared. Each of the unit photovoltaic modules may be composed of a support plate 10, first, second, and third frames 22, 24, 26, a heat insulator 30, and a solar panel 40, as disclosed in FIG. As for the specific configuration for each of these, the above content may be applied as it is.

When a plurality of unit photovoltaic modules are prepared, the first installation step of coupling any one of the unit photovoltaic modules to an arbitrary point on the outer surface of the support part 2 installed on the outer or upper part of the building follows (FIG. 14) in ①).

The support part 2 is a part to which a unit photovoltaic module is coupled and supports it, and may be formed of a support plate having a predetermined area or a plurality of support bars spaced apart from each other by a predetermined distance. FIG. 14 discloses a case in which the support part 2 is made of a support bar such as an I-beam.

The unit solar panel module coupling to the support part 2 may be made using various coupling means such as bolts, as well as in a coupling method as shown in FIG. 11 . In this case, a reinforcement strip may be further provided on the lower surface of the support plate as shown in FIG. 5 in some cases.

When the unit photovoltaic module is firstly installed at an arbitrary point of the support part 2, another prepared unit photovoltaic module is positioned above the firstly installed unit photovoltaic module and coupled to the support part 2 Perform the second installation.

The second installation for the other unit photovoltaic module is the upper side of the second frame 24 located at the front end of the support plate 10 among the prepared second frames 24 of other unit photovoltaic modules, as shown in the figure. It may be made in a manner of closely coupling the upper portion of the second frame 24 positioned at the rear end portion of the support plate 10 among the second frame 24 of the unit photovoltaic module installed primarily with the portion (Fig. See ② in 14).

If, as shown in FIG. 3 , the first coupling part 242 is formed in the upper portion of the second frame 24 positioned at the front end portion of the support plate 10 , and the second coupling portion 242 is formed in the rear end portion of the support plate 10 . When the second coupling portion 243 is formed in the upper portion of the frame 24, they are coupled while being in close contact with each other. At this time, a separate waterproof packing (not shown) may be interposed between the first and second coupling parts 242 and 243 .

Although the drawing discloses a configuration in which each of the two unit photovoltaic modules is vertically coupled to the support bar 2 over the first and second orders and coupled to each other at the same time, the present invention provides for two or more plurality of unit solar power modules. Of course, the case where the power generation module is vertically disposed is not excluded.

When two unit photovoltaic modules are vertically coupled to each other in a state in which they are coupled to the support part 2 over the first and second rounds, another unit photovoltaic module is prepared, respectively, and the first and second unit photovoltaic power generation modules are installed After locating on the left or right side of each of the modules, the tertiary installation is followed by coupling to the support 2 and at the same time coupling adjacent unit photovoltaic modules to each other.

The tertiary installation is, as shown in the figure, installed in the upper part of the third frame 26 located at the left end part of the support plate 10 among the third frames 26 of each other unit photovoltaic module and the first and second parts. Among the third frames 26 of each unit photovoltaic module, it may be made in a manner of closely coupling the upper portions of the third frame 26 positioned at the right end portion of the support plate 10 (in FIG. 14 ). , see ④).

At this time, as shown in FIG. 3 , a fourth coupling part 263 is formed on the upper portion of the third frame 26 located at the right end portion of the support plate 10 , and located at the left end portion of the support plate 10 . When the third coupling portion 262 is formed in the upper portion of the third frame 26, the third frames 26 of adjacent unit photovoltaic modules can be coupled to each other very easily. Of course, a separate waterproof packing may be interposed between the third and fourth coupling portions 262 and 263.

Alternatively, the third frame 26 may be formed as shown in FIG. 12A or 13A, and when the third frame 26 is configured in this configuration, one side third frame 26 and the other side third frame (26) adjacent to each other ( 26) Each of the protruding ends 264 is coupled by a closing strip 27 .

When the tertiary installation work is continuously performed, the exterior portion of the building is finished with a unit photovoltaic module, and accordingly, each unit photovoltaic module forms an integral structure with the building. That is, the photovoltaic module is not simply attached to the exterior of the building, but serves as a finishing material while forming a part of the building.

A separate finishing plate (not shown) is prepared for each of the unit photovoltaic modules located at the top, bottom, and left and right ends of the unit photovoltaic power generation module installed integrally with the building, and the upper side of the unit photovoltaic power module , the lower side, and when combined with each of the left and right sides, construction according to the present invention is completed. A plurality of vent holes are formed in the closing plate for the ingress of air, which are well known in the related art, and detailed description thereof will be omitted.

The drawing discloses a configuration in which unit photovoltaic modules are constructed continuously to the right based on the first and secondly installed unit photovoltaic modules, but unlike the first and second installed unit photovoltaic modules, based on It is self-evident that unit photovoltaic modules can be continuously constructed on the left or both left and right sides.

As such, the present invention manufactures an insulating material and a photovoltaic panel as an integral structure in a factory, and then transports it to a site requiring construction, and simply connects and assembles the unit photovoltaic modules at the site. In that it is possible to finish with a power generation module, very high constructability can be guaranteed, and even unskilled people can perform the work very easily.

In addition, the solar panel constructed according to the present invention can maximize the thermal insulation performance of the building in that each side of the insulating material provided in each unit photovoltaic module is in close contact with each other. And since the space under the adjacent solar panel has a structure in which each of the left and right as well as the top and bottom are completely communicated with each other, the heat generated in the photovoltaic power generation process can be removed by the air introduced from the outside in the shortest time.

In the above description, limited to preferred embodiments of the present invention, this is only an example, the present invention is not limited thereto and can be changed and implemented in various ways, and further, separate technical features are provided based on the disclosed technical idea. It will be obvious that it can be implemented in addition.
