Building integrated photovoltaic system is a photovoltaic power generation system built integrally with a building, and photovoltaic modules can form the outer shell of a building such as walls, windows, and roofs to produce electricity in an eco-friendly way. In particular, the exterior wall-type integrated building solar photovoltaic system, which is applied to the exterior wall of a building, can replace expensive building exterior materials, so it can also secure economic feasibility.

Due to the nature of the building integrated photovoltaic system installed outside the building, in the event of a fire in the building, a problem may occur in which the fire outside the building quickly spreads through the sealant of the building integrated photovoltaic system. The present invention can prevent this risk and increase the bonding strength between the photovoltaic module and the Z-bar.

1 schematically shows a part of a conventional building-integrated photovoltaic system according to an embodiment of the present invention.

The conventional building-integrated photovoltaic system largely consists of a photovoltaic module (2000) for photovoltaic power generation, a Norton tape (1300) for bonding the Z-bar frame (1000) and the photovoltaic module (2000), and the Norton tape (1300). ) may include a sealant that reliably bonds the Z-bar frame 1000 and the solar module 2000 to which they are temporarily bonded.

The conventional building integrated solar system is manufactured through the following sequence.

First, the Z-bar frame 1000 is fixed to the building by passing screws through the opening at the lower side of the Z-bar frame 1000 and the opening of the square tubular structure 4000 installed in the building.

One side of the Norton tape 1300 may be attached to the upper side of the fixed Z-bar frame 1000.

On the other hand, the norton tape 1300 refers to a spacer tape that has excellent double-sided adhesiveness and serves to fix the structure by maintaining its shape until the structural silicone is completely cured. It has a well-connected open cell structure, which is highly compatible with most of the sealants produced, and can be produced in the shape desired by the user. In addition, the Norton tape 1300 having fire resistance may be produced by changing the material.

In one embodiment of the present invention, the Norton tape 1300 may be Norton tape 1300, preferably having fire resistance.

At this time, the sealant may preferably be silicon, but may be changed according to the material and purpose of the Z-bar frame 1000 and the solar module 2000.

The photovoltaic module 2000 is placed on the opposite side of the Z-bar frame 1000 of the attached Norton tape 1300 and attached.

Thereafter, the sealant is injected into the space surrounded by the Z-bar frame 1000, the Norton tape 1300, and the solar module 2000, and the sealant is waited for curing.

The building-integrated photovoltaic system 1 made in this way has the advantage of being simple to manufacture, but the space between the photovoltaic module 2000 and the Z-bar frame 1000 is narrow when injecting the sealant, so the operator must be skilled. In addition, there is a disadvantage in that foreign substances such as moisture penetrate into the gap between the sealant aged over time and the Norton tape 1300 to damage the photovoltaic module 2000.

In addition, there is a risk that the sealant for weathering 3100 or a fire generated outside the building will quickly spread along the sealant and the Norton tape 1300.

Accordingly, the present invention for securing these disadvantages is schematically shown in FIG. 2 .

The cover frame 1200 is bonded to the outside of the second frame web 1152, the vertical member 1210 having a wave pattern concave groove formed at one end, and the sealant at the lower side of the vertical member 1210. The horizontal member 1220 extending toward the portion 3000 and in contact with a portion of the lower flange; may include, and a waterproof silicon 1240 may be positioned above the concave groove of the vertical member.

A more detailed description of this will be described later with reference to FIG. 7 .

5 schematically illustrates a filling operation of the inclined portion 1110 and the fire-resistant sealant 1400 according to an embodiment of the present invention.

The inclined portion 1110 according to an embodiment of the present invention may increase bonding strength by increasing a contact area between the fire-resistant sealant 1400 and the main frame 1100 .

In addition, the inclined portion 1110 does not exist and the cover frame 1200, the photovoltaic module 2000, the wing portion 1130, the upper flange 1154, and the junction portion 1120 of the space composed of The circumference of the space composed of the cover frame 1200, the solar module 2000, the wing part 1130, the upper flange 1154, the junction part 1120, and the inclined part 1110 is larger than the circumference. It can exert great effect.

In the inclined portion 1110 according to an embodiment of the present invention, the fire-resistant sealant filling tool 1410, which is preferably conical, is connected to the bonding portion 1120, the Norton tape 1300, and the solar module 2000. It provides a space that can easily penetrate into the space made of the fire-resistant sealant to facilitate the filling operation. When there is no inclined portion 1110, the fire resistant sealant filling tool ( 1410), the difficulty of filling the fire-resistant sealant 1400 increases due to the interference of the photovoltaic module 2000, and therefore, the fire-resistant sealant filling tool 1410 is not used for the photovoltaic module due to a worker's mistake. Damage to the lower surface of the building-integrated photovoltaic system 1 may result in a decrease in efficiency or even failure of the integrated solar system 1 due to damage to the lower surface of the 2000. In addition, the fire-resistant sealant 1400 is not uniformly filled, resulting in a decrease in the filling rate and bonding. intensity may decrease.

On the other hand, the fire-resistant sealant filling tool 1410 is a tool used to fill the fire-resistant sealant 1400 in a desired space, and in the present invention, the wing portion 1130, the upper flange 1154, the junction ( 1120), a tool for filling the space formed by the inclined portion 1110, the cover frame 1200, and the photovoltaic module 2000 with the fire-resistant sealant 1400.

In detail, the fire resistant sealant filling tool 1410 may be a sealant gun.

On the other hand, when the inclined portion 1110 is present, the generally conical fireproof sealant filling tool 1410 is easily placed in a space composed of the joint portion 1120, the Norton tape 1300, and the solar module 2000. Since it can penetrate into the photovoltaic module 2000, it is possible to prevent the worker from damaging the photovoltaic module 2000, thereby exhibiting the effect of improving the durability of the building integrated photovoltaic system 1, and the fire-resistant sealant filling tool 1410 ) is attached to the inclined portion 1110, which is made of metal, and the fire-resistant sealant filling tool 1410 is moved and filled, thereby minimizing the shaking of the fire-resistant sealant filling tool 1410 so that uniform filling is possible even if the operator's skill level is low. and by uniformly filling the space formed by the Norton tape 1300, the joint 1120, the inclined portion 1110, the cover frame 1200, and the solar module 2000 to be filled The filling rate of the fire-resistant sealant 1400 can be maximized. That is, the durability of the building integrated photovoltaic system 1 to be completed can be improved.

Meanwhile, since FIG. 5 schematically shows the fire resistant sealant filling tool 1410 according to an embodiment of the present invention, the size of the fire resistant sealant filling tool 1410 may preferably be larger than that shown in the drawing. More preferably, the space between the photovoltaic module 2000 and the Z-bar frame 1000 and the nozzle of the fireproof sealant filling tool 1410 may have corresponding sizes.

6 schematically shows a sealant construction method of the conventional building integrated solar system 1 and a sealant construction method of the present invention.

6A schematically shows a sealant construction method of the conventional building-integrated photovoltaic system 1.

When constructing a sealant for coupling the photovoltaic module 2000 and the Z-bar frame 1000, in the conventional building-integrated photovoltaic system 1, an operator uses the fireproof sealant filling tool 1410 to It should be constructed from the center of the module 2000 toward the outside. In this case, there is a risk that the lower portion of the photovoltaic module 2000 and the fire-resistant sealant filling tool 1410 collide with each other. That is, there is a risk of damage to the photovoltaic module 2000, and thus the skill level of the operator is very important.

In addition, depending on the attachment position of the solar panel 2000, it is impossible to place the fire-resistant sealant filling tool 1410 in the center of the solar module 1000 and install the solar module 1000 on the Norton tape ( 1300), the fire-resistant sealant 1400 had to be attached on the Z-bar frame 1000 in advance or the fire-resistant sealant filling tool 1410 having a special structure had to be used. In this case, since the sealant filling rate of the space where the sealant is filled is not perfect, problems such as poor adhesion and waterproofness may occur.

On the other hand, in the building integrated photovoltaic system 1 according to an embodiment of the present invention, the Norton tape 1300 and the fire-resistant sealant 1400 are used when installing the sealant for coupling with the Z-bar frame 1000. Due to the structure in which the Norton tape 1300 is protected by the wing portion 1130 and the fire resistant sealant 1400 is protected by the cover frame 1200 in a state where the positions of are reversed, the fire resistant sealant filling tool ( 1410) may work toward the center from the outside of the photovoltaic module 2000.

That is, to prevent the fireproof sealant filling tool 1410 from contacting the photovoltaic module 2000 to interfere with the operation or to prevent the photovoltaic module 2000 from being damaged by the fireproof sealant filling tool 1410 can be effective.

The building-integrated photovoltaic system 1 according to an embodiment of the present invention can exhibit the effect of being able to construct using the non-special general fire-resistant sealant filling tool 1410.

The building-integrated photovoltaic system 1 according to an embodiment of the present invention does not require a sealant to be attached in advance or a worker to work in an unstable posture, thereby achieving a filling rate of 100% to achieve a Z-bar frame and the sunlight It is possible to exhibit an effect of increasing adhesive strength between the modules 2000 and improving waterproofness.

7 schematically shows cross-sectional views of the cover frame 1200 and the waterproof silicone 1240 according to another embodiment of the present invention.

FIG. 7 schematically shows a cross section of the photovoltaic module 2000 and a cross section of the cover frame 1200 where the waterproof silicon 1240 is located.

The cover frame 1200 according to an embodiment of the present invention includes a space in which the weather sealant 3100 side is disposed, the cover frame 1200, the upper flange 1154, the joint 1120, the By partitioning the space formed by the inclined portion 1110 and the wing portion 1130, the fire occurring on the side of the weather sealant 3100 spreads to the fire resistant sealant 1400 and the norton tape 1300. moisture from the outside into the space formed by the cover frame 1200, the upper flange 1154, the joining portion 1120, the inclined portion 1110, and the wing portion 1130. penetration can be prevented.

According to one embodiment of the present invention, the cover frame 1200 can protect the fire resistant sealant 1400 and the norton tape 1300 from fire spreading from the sealant part 3000 side. When a fire occurs in the conventional building-integrated photovoltaic system 1 without the cover frame 1200, when the fire spreads to the sealant and the Norton tape 1300, the sealant and the Norton tape 1300 act as a fuse This allows the fire to spread faster.

If the fire-resistant sealant 1400 and the fire-resistant Norton tape 1300 are used as in the present invention, it is possible to prevent fire from rapidly spreading through the fire-resistant sealant 1400 and the fire-resistant Norton tape 1300, but the fire resistance The solar module 2000 is detached from the Z-bar frame 1000 due to damage to the sealant 1400 and the fire-resistant Norton tape 1300, and secondary damage may occur when falling.

The cover frame 1200 is a metal material, and prevents the fire-resistant sealant 1400 and the Norton tape 1300 from being directly damaged by fire, and in the event of a strong fire, the inflow through the cover frame 1200 It is not possible to prevent the fire-resistant sealant 1400 and the Norton tape 1300 from being damaged by heat, but compared to the building integrated solar system 1 without the cover frame 1200, the fire-resistant sealant Secondary damage can be minimized by delaying the time at which the 1400 and the Norton tape 1300 are damaged, and during that time, actions such as fire suppression and evacuation.

In addition, the cover frame 1200 according to an embodiment of the present invention can exert an effect of preventing moisture from flowing into the photovoltaic module 2000 .

More specifically, the weather sealant 3100 can prevent moisture from entering the photovoltaic module 2000 and the norton tape 1300 at the beginning of the construction of the building integrated photovoltaic system 1, but the time When the sealant for weathering 3100 is cured while flowing, gaps may be formed, and moisture may flow into the gaps. When the cover frame 1200 is present, it is possible to exhibit an effect of improving the durability of the building-integrated photovoltaic system 1 by preventing the inflow of moisture due to the curing of the weather sealant 3100 .

In addition, the cover frame 1200 according to an embodiment of the present invention prevents a tool from damaging the side surface of the photovoltaic module 2000 due to a worker's mistake during construction of the sealant part 3000 by a worker. can do.

The solar module 2000 according to an embodiment of the present invention includes a glass 2100 that protects the surface, a plurality of cells 2300 that absorb light energy to generate electrical energy, and a plurality of cells 2300. It includes an EVA (2200) for bonding and protecting, a back sheet (2400) for protecting the EVA (2200) and the Cell (2300), and by the Norton tape (1300) and the fire-resistant sealant (1400) -Can be attached to the bar frame (1000).

The cover frame 1200 according to an embodiment of the present invention further includes the waterproof silicone 1240 located in a space between the cover frame 1200 and the side surface of the photovoltaic module 2000, and the waterproof The silicon 1240 can prevent moisture from entering the space between the cover frame 1200 and the side surface of the solar module 2000 and protect the EVA 2200, which is vulnerable to moisture.

More specifically, the EVA 2200 of the photovoltaic module 2000 is vulnerable to moisture, and when exposed to moisture, insulation breakdown occurs and the performance of the photovoltaic module 2000 decreases or does not work. can In general, this problem can be prevented by using the weather sealant 3100 installed between the photovoltaic module 2000 and the photovoltaic module 2000, but exposed to the outdoors for a long period of three to ten years or more after construction. Since the products of the sealant for weathering 3100, which have durability that can be withstood, are relatively expensive, there is a problem in that the initial installation cost increases. In the case of using the inexpensive sealant for weathering 3100 for the economic feasibility of the building integrated photovoltaic system 1, when a period of two to three years or more elapses, the silicone for weathering is hardened and cracks may occur in the silicone for weathering. If moisture such as rainwater or the like flows in through the gap, the insulation of the EVA 2200 may be destroyed and the photovoltaic module 2000 may fail.

In the cover frame 1200 according to an embodiment of the present invention, the waterproof silicon 1240 is located on an inner surface, and between the inner surface of the cover frame 1200 and the side surface of the photovoltaic module 2000 The positioned waterproof silicone 1240 prevents moisture from entering between the cover frame 1200 and the glass 2100, so even when the inexpensive weather sealant 3100 is destroyed, the EVA 2200 Moisture protection can be provided.

In addition, compared to the amount of the sealant for weathering 3100 injected into the sealant part 3000, the amount of the waterproof silicone 1240 located in the space between the cover frame 1200 and the side of the solar panel is small. Using the expensive waterproof silicone 1240, it is possible to maintain waterproofness for a long period of time, as in the case of using the expensive weather sealant 3100, and the cost consumed at this time is also higher than that of using the expensive weather sealant 3100. It can be cheap and economical.

On the other hand, the waterproof silicone 1240 can be integrally manufactured by a machine in the process of manufacturing the cover frame 1200, and can be more uniformly attached to the building compared to the case where a worker directly works and attaches the waterproof silicone 1240. The effect of improving the durability of the integrated photovoltaic system 1 can be exhibited.
