Description

  The present invention relates to a mounting structure and a mounting method when a solar cell module for obtaining power by photovoltaic power generation is mainly installed on a veranda or a balcony of a building.

  When a space for installing the solar cell module cannot be secured on the roof or the ground such as an apartment house, the veranda or balcony is suitable as a solar cell module that can receive enough sunlight. . There is no strict distinction between verandas and balconies, but those with a roof are often called verandas and those without a roof are often called balconies. For the sake of simplicity, the expression veranda will be used hereinafter for both of these or other similar structures.

  Prior art documents such as the following exist as techniques for installing solar cell modules on the veranda, but they are large: (1) installed inside the veranda, (2) installed outside the veranda, (3) veranda (4) Attached using a veranda chassis, (5) Attached separately from a handrail or a veranda chassis, and the like.

  (2) In the installation outside the veranda, solar cells are installed outside the veranda's fence and waist wall, so there are no objects that block sunlight, so the solar cells receive more sunlight. There is a possibility of generating more electricity.

On the other hand, in the technique of installing and fixing on the inside of the veranda fence and the waist wall, there is a possibility that sunlight is blocked by the veranda on the upper floor. In particular, in the summer when the sun rises, it is highly likely that it will be difficult to receive sufficient sunlight in the solar cell inside the veranda fence and the waist wall.

  In Patent Document 1, the outside of the south beland parapet 1 is inclined upward, and a solar cell panel is attached to the inclined surface.

  In Patent Document 2, a solar cell is attached to a handrail body made of a support and a headboard.

  In Patent Document 3, a fixing member is attached to a flange portion of a veranda, and after the upper portion of the solar cell is engaged with the fixing member, the lower portion of the solar cell is fixed to the upper portion of the rail of the veranda.

  In Patent Document 4, a frame body of a solar cell panel is fixed to the outside of a waist wall of a veranda using a connecting member.

  Patent document 5 supports a pole material in the center part of the solar cell back surface, and fixes this pole material to the fence of a veranda firmly.

  Patent Document 6 is a solar cell device installed so as to sandwich a wall body whose upper end is open, and extends outside the side portion of the solar cell, and then is not U-shaped. It has a support material that is folded back to the light-receiving surface side and extends to the back surface of the solar cell, and is provided with an air circulation port where the support material does not exist in the upper part of the space between the wall body and the solar cell. is there.

  Patent Document 7 uses so-called support pillars, and both ends of the pillars are pressed against two independent structures separated by a certain distance such as a floor and a ceiling of a building or opposite wall surfaces. The plurality of pillars support the solar cell at a specific position and angle in the air.

  Patent Document 8 includes a solar cell module and a pedestal that supports the light receiving surface of the solar cell module in the solar radiation direction, and a first columnar body and the first columnar body on the back side of the solar cell module. A connecting portion that rotatably supports one end of the first columnar body, a second columnar body that can fix the other end of the first columnar body and the connecting portion, and an upper end portion of the solar cell module. And the other end of the second columnar body is rotatably supported by the gantry.

The patent documents 1 to 8 are classified as follows.

  When the solar cell module is provided in the veranda or in the upper part of the veranda as in Patent Literature 3 and Patent Literature 7, the use space of the veranda is narrowed, which is not preferable.

  In the case where the solar cell module is provided on the veranda using a casing as in Patent Document 1, Patent Document 4, and Patent Document 6, this is possible only when a sufficient installation space such as a wall can be secured.

  For example, in Patent Document 1, in order to secure a required area in order to attach a solar cell to a parapet, it is necessary to form the outside of the parapet on an upward inclined surface. As a result, the rising dimensions of the parapets become large and the frame construction becomes troublesome. Moreover, it cannot be constructed without an external scaffold, and it is virtually impossible to remove the solar cell from the parapet in order to attach the solar cell to the parapet, and it cannot be replaced when the solar cell fails or is damaged.

  In Patent Document 2, a solar cell is attached to a handrail main body composed of a column and a headboard, and the column and the headboard directly receive the load load of the solar cell.

  In Patent Literature 3, it is difficult to attach the fixing member to the flange portion of the veranda with sufficient fixing strength, and the work of fixing the lower portion of the solar cell to the upper portion of the veranda fence is similarly complicated. .

  Patent Document 4 cannot be attached only from the inside of the veranda, and needs to be performed after an expert of construction work assembles a scaffold on the outside of the veranda.

  In Patent Document 5, since a solar cell is attached to the outside of a veranda fence, a load is applied to the fence (handrail).

  In Patent Document 6, a waist wall of a condominium veranda, which is a fixed object, is interposed, and the inside of the curved portion of the support material is in contact with the top of the waist wall of the veranda and places a load on the waist wall.

  Patent document 7 is installed in a veranda by a support pillar, and becomes a hindrance when the veranda is used for other purposes.

  In Patent Document 8, since the frame is directly installed on the fence portion of the veranda, the load on the solar panel cannot be sufficiently supported when subjected to strong wind or the like, and there is a concern about the risk of falling or the like.

  The object of the present invention is to eliminate the disadvantages of the conventional example, and to install the solar cell module outside the veranda without applying a load to the fence (handrail), and to perform construction without an external scaffold, which is simple and easy. Another object is to provide a solar cell module mounting structure and mounting method that can be installed at low cost.

  In order to achieve the above object, the present invention as claimed in claim 1 as a structure for mounting a solar cell module, includes: The gist is that the portion is inserted and the sheath tube is filled with non-shrink mortar and fixed.

  The present invention as claimed in claim 3 as a method for attaching a solar cell module is to open a bolt through hole in a veranda floor plate, attach a plate with a sheath tube with a bolt, and attach a sheath tube to the outside of the handrail installation location on the veranda floor, The gist is to fill the bolt through hole with grout, insert the leg portion of the gantry frame with the solar cell panel installed in the sheath tube, and fill the sheath tube with non-shrink mortar and fix it.

  According to the present invention, the non-shrinkable mortar is filled between the sheath tube and the solar cell module support portion, thereby enduring a bending load due to wind pressure or the like. Moreover, since the gantry is divided into the sheath tube portion and the module support portion, construction without an external scaffold is possible.

  Furthermore, in addition to installation on the rooftop, it can be installed easily, easily and at low cost on places other than the rooftop such as the walls of existing buildings.

  Moreover, the dimension error (horizontal direction, inclination) of the existing housing can be absorbed by installing the gantry frame into the sheath tube.

  As described above, the solar cell module mounting structure and mounting method of the present invention allows the solar cell module to be installed outside the veranda without applying a load to the fence (handrail), and can be constructed without an external scaffold.
