Description

A power generation roof unified with building}

The present invention relates to a solar roof, and more particularly, the roof of the building itself as a solar roof, but can completely prevent leakage due to rainwater, as well as the outside air can be introduced through the solar cell module. The present invention relates to a building-integrated photovoltaic roof that can quickly remove heat generated from a solar cell module.

There is a growing interest in solar power as an alternative energy source due to the depletion of near-by resources. Photovoltaic power generation is an integrated technology that converts sunlight entering the earth into electrical energy. It is not only eco-friendly, but once the device is installed and operated, it can produce electricity without the need for energy input. There is an advantage, and the application range is gradually increasing.

In general, photovoltaic power generation is a unit photovoltaic module including a plurality of solar cells, a wire electrically connecting the solar cells, and a film or protective glass to protect the solar cells from the external environment. Operate in series or parallel connection. In order to apply such a solar cell module to a building, the most widely used from the past to the present is a method of mounting a solar cell module on a roof of an existing building.

This method can be implemented by simply fixing the finishing frame that tightly constrains the solar cell module to the roof, which eliminates the need to dismantle the existing building or to construct a new structure for solar cell module installation. have. However, this method has a disadvantage in that the appearance of the building becomes bad in that the solar cell module assembly is installed on the roof of an existing building. In addition, this method is to fix the finishing frame to the roof using a fastening means such as bolts, there is a problem that leaks into the building through the through hole of the fastening means formed in the fixing process.

On the other hand, in order to solve the problem of the method of installing the solar cell module using the finishing frame as described above, the currently widely researched method is the building integrated solar power roof (Building Integrated roof) consisting of the solar cell module itself as the roof of the building Photovoltaic, BIPV). Republic of Korea Patent No. 0989599 uses this approach and an embodiment thereof is disclosed in FIG. As can be seen from the figure, this method has the advantage of not only reducing the cost for roof construction but also maintaining the building appearance as originally intended by constructing the roof itself of the building as a solar cell module assembly.

However, this method does not fundamentally solve the problem of water leakage into the building due to rainfall in that a roof is formed by interconnecting a plurality of solar cell modules that operate independently of each other. Moreover, the solar cell module generates a considerable amount of heat during its operation, and most of these methods currently proposed focus only on replacing the roof itself with the solar cell module. Removable structure is not presented at all, there is a problem that the reality is very poor.

The main drainage guide pipe 10 is a part for supporting the building integrated photovoltaic roof according to the present invention and at the same time to guide the rainwater that can be introduced through the roof to the outside, fixed to the top of the fixed bar (1) of the building A plurality of bars are installed at regular intervals from each other in a state perpendicular to the bar. The fixing bar (1) is typically configured to reinforce the lower transverse bearing capacity of the building roof, a plurality of spaced apart from each other in the form of a horizontal bar is installed. The fixing bar may be made of C-shaped steel.

Upper and left sides of each of the main drainage guide pipes 10 are provided with first and second mounting ends 120 and 130 extending in a horizontal direction. Each of the first and second mounting stages 120 and 130 is a portion in which an end of the solar cell module 30 to be described later is mounted. Unexplained reference numerals 122 and 132 are vertical ends, respectively, and are means for preventing the end of the solar cell module mounted on each of the first and second mounting ends 120 and 130 from being out of position by external force.

In addition, the lower left and right sides of the main drainage guide pipe 10 are provided with first and second drainage portions 160 and 170. Each of the first and second drainage portions 160 and 170 has drainage passages 162 and 172 formed by the first and second side walls 164 and 174. Each of the first and second side walls 164 and 176 is a portion in which each end of the auxiliary drainage guide pipe 20 to be described later is mounted, and the drawing discloses a case having an inclined angle at an angle and protruding obliquely. Only one example may be variously changed to a structure that can form the appropriate drainage at the same time to properly mount the auxiliary drainage pipe end.

Reference numerals 166 and 176, respectively, are fixed ends. Each of the fixed ends 166 and 176 is a part necessary for fixing the main drainage guide tube 10 to the fixing bar 1 using a coupling means called a holder 50. That is, in a state in which the main drainage guide tube 10 is placed on the fixing bar 1 and the ring 52 provided in the holder 50 is coupled to the respective fixed ends 166 and 176 of the main drainage guide tube. The main drainage guide pipe 10 is attached to the fixed bar 1 by tightly constraining the extension end 54 of the holder to the fixed bar 1 by using a bolt. However, the specific configuration of each fixed end is not limited to the specifically disclosed structure because it can be changed in various ways, it is obvious that the specific configuration of the holder 50 will also be changed according to the configuration of the fixed end. .

When the main drainage guide pipe 10 is installed on the fixed bar 1 using the holder 50, the present invention provides a heat shield between the fixed bar 1 and the main drainage guide pipe 10 as shown in the drawing. The case where 60 is mediated is not excluded. Typically, each of the fixed bar 1 and the main drainage pipe 10 may be made of a metal material. In this case, the heat generated from the solar cell module 30 is naturally fixed through the main drainage pipe 10. It is transmitted to 1) and it is possible to raise the temperature of the roof.

For this reason, the heat transfer member 60 is interposed between the main drain pipe 10 and the fixed bar 1, which is a metal material, so that heat transfer between the main drain pipe 10 and the fixed bar 1 can be appropriately blocked. do. In this case, the heat shield 60 is preferably made of a synthetic resin material, and the holder 50 may be preferably made of a synthetic resin material for proper heat shielding.

The auxiliary drainage guide pipe 20 is a portion for properly inducing rainwater that can be introduced through the roof, consisting of a plurality of spaced apart from each other by a predetermined interval, orthogonal to the opposite main drainage guide pipe (10) Is installed. More specifically, both end portions of the auxiliary drainage guide pipe 20 are preferably placed on the upper portion of each of the first and second side walls 166 and 176 of the main drainage guide pipe 10.

Each auxiliary drain guide pipe 20 is provided with a drainage flow path 22 formed by the left and right walls 24. Accordingly, the rainwater introduced through the roof of the building is guided to the drainage paths 162 and 172 of the main drainage pipe 10 through the drainage inlet 22 of the auxiliary drainage pipe 20 and is naturally discharged to the outside of the building. .

On the other hand, the present invention proposes a case in which the auxiliary drainage guide pipe 20 is installed to be inclined to guide the rainwater introduced into the auxiliary drainage guide pipe 20 more naturally to the main drainage guide pipe 10. That is, the auxiliary drainage guide pipe 20 is the first and the second side wall in a state in which one of the first and second side walls 166 and 176 of the main drainage guide pipe 10 is formed with a higher vertical height than the other. (166, 176) That is what is placed in the upper part.

The drawing discloses a case in which the vertical height h2 of the second side wall 176 is formed higher than the vertical height h1 of the first side wall 166. In this state, when both ends of the auxiliary drain guide pipe 20 are placed in the first and second side walls 166 and 176, the end portion of the auxiliary drain guide pipe 20 placed in the second side wall 176 may be disposed in the first side wall ( 166) is higher than the end portion of the auxiliary drainage pipe 20 placed. Therefore, when the rainwater flows into the auxiliary drainage pipe 20 as shown in FIG. 4, the rainwater naturally moves to the right main drainage pipe point according to the gradient and is led to the drainage of the main drainage pipe.

The solar cell module 30 is a device for converting sunlight incident to the roof of the building into electrical energy, a plurality of solar cells, wires for electrically connecting the solar cells as known in the art, and It may include a film or a protective glass to protect the solar cells from the external environment, each outer edge is finished by a finishing frame made of a metal material.

Specifically, the solar cell module 30 is installed in the first, second mounting end (120, 130) of the main drain pipe (10) opposite ends of each side. In this case, the other two end portions (more specifically, the finishing frame end 32 of each solar cell module) of each solar cell module 30 that is not placed in the first and second mounting ends 120 and 130 are illustrated in FIG. 2. Likewise, it is located in the drainage flow path 22 of the auxiliary drainage guide pipe 20.

The finishing frame end 32 of the solar cell module 30 in contact with each other in the drainage flow path 22 of the auxiliary drainage guide pipe 20 may be tightly coupled to each other by a separate adhesive means. Even if the adhesion is not completed or the adhesive site is damaged over time, the rainwater that penetrates between the solar cell modules 30 in the drainage flow path 22 of the auxiliary drainage guide pipe is interposed with the main drainage guide through the drainage flow path 22. Appropriate guidance to the tube 10 is as described above.

The closing cap 40 is a part to prevent the rain water to flow in by closing the space between the solar cell module 30 is placed in the main drain pipe (10). Specifically, the interspace S formed at the end of the solar cell module 30 facing each other by being placed in the first and second mounting ends 120 and 130 of each main drainage guide pipe 10 is sealed.

The upper end of the cap 40 is provided with first and second horizontal ends 42 and 44 which protrude in left and right directions, and below the first and second insertion ends 46 and 48 which protrude downward. ) May be formed. In this case, the first and second insertion ends 46 and 48 are inserted into the space S between the solar cell modules 30 facing each other at an upper portion of the main drainage guide tube 10, and the first and second horizontal ends. 42 and 44 press the upper surface of both ends of the solar cell module 30 to tightly constrain the solar cell module.

In addition, the present invention does not exclude the case where the base panel 3 and the heat insulating finisher 5 are further provided between the fixed bar 1 and the main drainage guide pipe 10. As a specific example of this, a schematic cross-sectional configuration diagram and a schematic construction diagram of a building integrated solar power roof are disclosed in FIGS. 5A and 5B, respectively.

The base panel 3 is a part fixedly installed on the fixing bar (1). The material is made of a metal, and as shown in the figure, it may be formed in the longitudinal direction stepped portion protruded downwardly spaced apart from each other by a molding operation. The stepped part is for enhancing the rigidity of the base panel. When the stepped part is provided in the base panel, the stepped parts of adjacent base panels overlap each other and are placed on the fixing bar 1. In addition, a plurality of through holes may be formed in the base panel to enhance the sound absorbing function.

The heat insulating finisher (5) is a portion that performs a sound absorbing function as well as a heat insulating function. When the heat insulating finisher 5 is provided, a support bar not shown may be further provided to easily install the heat insulating finisher 5. The support bar is made of Z bars widely used in the related art, and are installed on the base panel 3 in a state spaced apart from each other by a predetermined interval, and the heat insulating finisher 5 is installed in the interspace partitioned by the support bar. . The support bar may be fixed to the fixing bar 1 together with the base panel 3 by the fastening plate 7.

As in this embodiment, when the base panel 3 and the heat insulating finish material (5) is further provided between the fixed bar (1) and the main drain guide pipe (10), the main drain guide pipe (10) is a heat insulating finish material (5 ) It is installed on the top. Since the heat insulating finisher 5 is not easy to transfer heat due to its own characteristics, it is possible to easily block heat transmitted through the main drainage pipe 10 even though the heat shield 60 is not mediated as in the case of the above-described embodiment. have.

However, when the thermal barrier material 60 is mediated, since the thermal barrier effect may be further increased, the present invention provides a thermal barrier material 60 between the main drainage guide pipe 10 and the thermal insulation finish material 5 as disclosed in the drawings. It does not exclude the case where it is mediated. In this case, in the state in which the heat shield 60 is mediated between the main drainage guide pipe 10 and the heat insulating finisher 5, the main drainage guide pipe 10 is fixedly coupled to the heat insulating finisher 5 by the holder 50.
