Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof-

The present invention relates to a building-integrated photovoltaic (PV) roof system, and more particularly, to a solar-powered building roof-in-building system capable of firmly mounting a solar panel on a gutter panel constituting a roof of a building, will be.

In general, roofs of buildings are constructed in various forms, and roof panel assemblies using panels have recently been widely used.

Such a roof panel assembly has been previously filed with Korean Registered Patent No. 10-1444454 (Publication date 2014.10.02).

Referring to FIG. 1, a conventional roof panel assembly will be described. A lower panel 3 is installed on a frame (C-shaped steel) 1 installed on a ceiling of a building, (Heat insulating material) 5 is laminated. And the upper panel 7 is laminated on the upper surface of the heat insulating board 5. [

In this case, the conventional roof panel assembly is constructed such that independent components such as the lower panel 3, the heat insulating board 5, and the upper panel 7 are sequentially stacked, and a Z bar 6 are integrally fastened from the upper panel 7 to the lower frame 1.

The upper panel 7 is provided with a bent portion 7a at one side so that a plurality of the upper panel 7 can be installed along the longitudinal direction of the frame 1 and the bent portion 7a of the adjacent upper panel 7 is provided at the other side. And an engaging portion 7b is provided. An insert clip 9 for fixing the upper panel 7 to the Z bar 6 interposed between the heat insulating boards 5 is provided between the overlapping bent portion 7a and the fitting portion 7b.

On the other hand, a solar panel structure may be installed on a roof panel having the above structure to generate electric energy using solar light.

In this case, the conventional solar panel installation structure may have a structure in which a frame is provided to the overlapping portion of the upper panel 7 via a separate fixing bracket, and a solar panel is installed on the frame.

However, the conventional solar panel installation structure is mostly installed at a certain height above the upper panel 7. As a result, there is a concern that the solar panel installation structure may be damaged due to factors such as a typhoon or other natural disasters accompanied by strong wind and rain.

The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a solar panel capable of firmly installing a solar panel on an upper part of a gutter panel constituting a roof of a building and facilitating drainage in rainy weather, And to provide a method of constructing the solar power generation roof system.

In order to accomplish the above object, the present invention provides a building integrated photovoltaic (PV) roof system, comprising: a bending part at one side so as to be successively arranged in a neighboring direction; A plurality of support members installed between the overlapped portions of the gutter panels and spaced apart from each other along the arrangement direction of the gutter panels; A solar panel member successively disposed on both sides of the support member so as to support both bottom surfaces; And a closure member joined to the gap between the upper surface of the solar panel member and the concealed closure member.

According to the present invention as described above, the solar panel member can be simply and firmly installed on the upper part of the gutter panel constituting the roof of the building through the supporting member and the closing member for supporting and fixing the solar panel member.

In addition, since the drainage structure including the rainwater receiver is applied to a gap between a plurality of solar panel members arranged in succession, the rainwater can be prevented from flowing into the gutter panel, thereby improving the watertightness performance.

In addition, since the rainwater introduced into the gaps between the solar panel members arranged successively is guided to the upper surface of the gutter panel, the drainage can be smoothly performed.

In addition, when a part of the solar panel assembly is damaged by a typhoon or a hail, even if rainwater or hail is introduced through the damaged part, it is possible to prevent the occurrence of leakage on the roof due to drainage to the outside through the surface of the gutter panel.

Further, by fixing the support member to the Z-bar structure of the roof, the load of the solar panel assembly can be supported and the structure can be reinforced.

In addition, by providing a worker inspection passage between the successively arranged solar panel assemblies at a predetermined interval, smooth maintenance and repair can be achieved.
