Description

  The present invention relates to a new structure for attaching a solar cell module to a building such as a house.

  Solar cells are attracting attention and are spreading from the viewpoint of the global environment. The installation of the solar cell modules is usually arranged along an inclined roof facing south. In cold climates, solar cell modules may be attached to the south facing wall or veranda to avoid power generation being blocked by snow accumulation when installed on the roof.

  For example, in mounting to a wall surface, as shown in Japanese Patent No. 4556215, module mounting means for mounting a module on a pair of main members made of L-shaped steel material fixed in parallel to the upper and lower surfaces of the wall, and the module mounting means It is known to install a module along a wall surface with a cover mounting means that covers a gap around each mounted module.

  This solar cell array platform wall surface installation system has been systematized so that all the members covering the wall surface and the covers covering the gaps around each mounted module can be attached via the main material, Since the module mounting means can be mounted after temporarily placing the module to be mounted on the mounting piece, it can be mounted by one person when mounting the module on the wall surface.

  Moreover, in the attachment to a veranda, as shown in Unexamined-Japanese-Patent No. 2002-1111033, it is a solar cell apparatus installed so that this may be clamped to the wall body by which the upper end part was open | released, After extending outward from the side part, it has a support member that is folded back to the non-light-receiving surface side in a U shape and extended to the back surface of the solar cell, and is located above the space between the wall and the solar cell. A device provided with an air circulation port without the support material is known.

  In this solar cell device, when the solar cell device is installed and fixed on the waist wall or fence of the veranda, an amateur who is not an expert in the construction work installs the solar cell outside the waist wall or rail of the veranda. The work can be done only on the inner side, and there is no fear of dropping the solar cell device by mistake, and it can be securely and securely fixed.

  Moreover, as what is installed in a ground apart from a building, as shown by Unexamined-Japanese-Patent No. 2010-258024, it is a support structure which supports a several solar cell module with a predetermined inclination angle with respect to a horizontal surface. A concrete block installed in correspondence with a plurality of support locations of each solar cell module, and a mounting bracket supported on each concrete block, the mounting bracket standing up on the concrete block The solar cell module is fastened to be slidable with an external force of a predetermined value or more along the extending direction of the upper portion of the support piece with respect to the upper portion of the support piece. What is being known.

  In this solar cell module support structure and its mounting bracket, there is provided a support structure that can stably support the solar cell module at a low cost and its mounting bracket against soft ground and instability of the ground from a long-term viewpoint. It can be provided.

Japanese Patent No. 4556215 JP 2002-111033 A JP 2010-258024 A

  When installing a solar cell module directly on the outer wall surface of a building such as a general house, the wall surface that can be attached is limited so that windows and ventilation holes are not blocked. There is a problem that it is less than the rated power generation amount (approx. 3KW or more) commensurate with the amount. If the rated power generation amount is small, a cost that is not proportional to the number of panels such as a power conditioner is applied, so the installation cost may not be recovered.

  In addition, as shown in JP-A-2002-111033, when a solar cell module is attached only to a waist wall or a fence of a house veranda, when attached to a handrail of a house veranda that is old and lacks strength, There is a problem that the veranda of the house cannot withstand the weight of the battery module.

  Moreover, in the thing of Unexamined-Japanese-Patent No. 2010-258024 which installs on the ground independently from the building shown previously, the large land which can be occupied besides a house is needed, and it becomes unsuitable for a general household. ing.

  In addition, when installing a solar cell module parallel to the outer wall surface of the house, there is no problem of snow accumulation when it is installed on the roof, but there is a problem that it is not possible to receive sunlight efficiently during the day when the sunlight is strong. .

  Therefore, the present invention can attach more panels than the case where the solar cell module is directly attached to the outer wall surface of the building, is firmly attached without imposing a burden on the building, and is efficient without occupying a large land. It aims at providing the attachment structure to the building of a solar cell which can receive sunlight.

  According to the first aspect of the invention, the solar cell is attached to the building with a boulder 40 embedded in the ground E away from the building 1, and between the parapet 4 and the veranda 5 of the building 1 and the boulder 40. A plurality of beam members 10, 20, and 30 are slanted to each other, and a solar cell module S is attached to a desired position of the beam members 10, 20, and 30.

  The structure for attaching the solar cell to the building of the invention of claim 2 is such that the upper attaching portions 11 and 21 of the beam members 10 and 20 are substantially firmly fixed to the upper portions of the parapet 4 and the veranda 5 of the building 1. The lower mounting members 13 and 23 of 10 and 20 are loosely fitted with the boulders 40 in the vertical direction.

  The structure for attaching the solar cell to the building of the invention of claim 3 is such that the upper attachment portion 31 of the beam member 30 is loosely fitted vertically with the upper portion of the parapet 4 or veranda 5 of the building 1 and the lower portion of the beam member 30. The mounting member 33 is fixed to the boulder stone 40 almost firmly.

  According to the invention of claim 1, a boulder 40 is embedded in the ground E away from the building 1, and a plurality of beam members 10, between the upper part of the parapet 4 or the veranda 5 of the building 1 and the boulder 40. Since the solar cell module S is attached to the desired position of the beam members 10, 20, 30 by attaching the solar cell module S diagonally, the solar cell module S can be attached to the window 1 or the like. More panels can be attached than when directly attaching to the outer wall surface 2.

  Also, a plurality of beam members 10, 20, and 30 are diagonally spanned between the upper part of the parapet 4 or veranda 5 of the building 1 and the bundling stone 40, and the solar cell module is placed at a desired position of the beam members 10, 20, and 30. By attaching S, the boulders 40 can be embedded in the ground E at a position that can be occupied, so that sunlight can be received efficiently without occupying a large area.

  According to the second aspect of the present invention, the upper mounting portions 11 and 21 of the beam members 10 and 20 are substantially firmly fixed to the upper portions of the parapet 4 and the veranda 5 of the building 1, and the lower mounting members 13 of the beam members 10 and 20. , 23 are loosely fitted with the boulders 40 in the vertical direction, so that unnecessary force is not applied to the beam members 10, 20 and the building 1 even if the boulders 40 move due to freezing or sinking.

  According to the invention of claim 3, the upper mounting portion 31 of the beam member 30 is loosely fitted in the vertical direction with the upper part of the parapet 4 or the veranda 5 of the building 1, and the lower mounting member 33 of the beam member 30 is attached to the bundling stone 40. Because it is almost firmly fixed, unnecessary force is not applied to the upper part of the beam 30 or the parapet 4 or the veranda 5 of the building 1 even if the boulder 40 moves due to frost heaving or sinking. It can be attached firmly without hanging.
