Description

  TECHNICAL FIELD The present invention relates to a stand device for a solar power generation device that generates power using solar energy, and in particular, solar power generation in which solar power generation devices installed on a flat roof or the like are arranged at a predetermined sunlight incident angle. The present invention relates to a gantry device.

  2. Description of the Related Art In recent years, a solar power generation device that is arranged on a roof of a house using a solar cell that receives sunlight and converts it into electricity has become popular. Thus, as used in such a device, a solar cell module product in which a plurality of solar cell elements are connected in accordance with various roof shapes is made.

  There are various methods for attaching such solar cell modules to the roof, using a roof-integrated solar cell module manufactured integrally with a roof member, or a vertical beam or a horizontal beam on a roof tile. There is an installation method called a so-called roofing type in which a frame is assembled and a solar cell module is installed there.

  By the way, since these conventional installation methods are premised on installation mainly on inclined folded-plate roofs or tile roofs, concrete floors with a substantially flat roof top like the roof of a building. If the solar power generation device is installed horizontally on the roof (referred to as a flat roof) as it is, the incident angle of sunlight on the solar cell module becomes shallow, and thus the amount of power generation is usually reduced by about 30 to 40%. There was a thing.

  In order to solve such a problem, a method for tilting and supporting the solar cell module using a mount for tilting the solar cell module is often employed.

  Specifically, an anchor is buried by first making a hole in a concrete roof which is a horizontal installation surface, and a foundation fixed to the anchor is formed by a heavy object such as concrete. By doing so, the foundation is fixed to the installation place by anchor bolts or the like driven into the roof, and the solar cell module can be supported by the wind and the like by the weight of the foundation and the fixing force of the anchor bolt. .

  When the foundation is fixed in this way, a base rail made of a long metal member is installed between a plurality of bases, and a support bracket for supporting the solar cell module is fixed on the base rail. The solar cell module is supported and fixed by.

  At this time, the installation angle of the solar cell module can be changed by changing the length of the support bracket, for example, by shortening the support bracket on one side, the longest support bracket on the other side, and the intermediate support bracket in the middle length. The power generation efficiency at the time of solar power generation can be improved.

However, there are some problems with the conventional method using the gantry.
First of all, there is a problem that the construction period is long for foundation work.
Moreover, in order to hit an anchor on a flat roof, the structure of the installation surface may be damaged, and rainwater may enter from there, or the life of the installation surface may be shortened.

  In addition, it is necessary to drive into the reinforcing bar of the concrete floor that constitutes the flat roof from the strength aspect, but it is difficult to grasp the position of the reinforcing bar or the position where the anchor can be hit is limited by the pitch of the reinforcing bar, so it is optimal for the flat roof There was a problem that solar cell modules could not be installed at positions and orientations, and the number of installed solar cell modules could be limited or the amount of power generated could be reduced.

Instead of fixing with an anchor, a method of fixing the gantry on the flat roof with an adhesive is also conceivable. However, in general land roofs, a waterproof sheet is often laid on the concrete floor, and since this waterproof sheet deteriorates, it is necessary to replace the waterproof sheet regularly. It is necessary to remove the support frame once.
If the gantry is fixed with an adhesive, there is a problem that it becomes difficult to remove the gantry when replacing the waterproof sheet.

  In order to solve such a problem, a plurality of photovoltaic power generation devices each provided with a gantry having different heights on opposite sides of the solar cell module are arranged along the arrangement direction of the gantry, and the adjacent photovoltaic power generation There has been reported an example in which the apparatus is connected to each other by a connecting member provided on both bases, and a weight member is provided on the base (see Patent Document 1).

  In this way, the installation angle of the solar cell module is inclined by providing the gantry with different heights on the opposite sides of the solar cell module, and a plurality of photovoltaic power generations are made by connecting members provided on the gantry. The devices are connected to each other and integrated with a spread, and a weight member is provided on the gantry, so that the set of photovoltaic power generation devices is fixed only by being placed on the flat roof.

  However, in this example, the width of the gantry must be matched to the width of the solar cell module in advance, and there is a problem that the modules to be used are limited. Moreover, since it is configured for a flat roof, there is a problem that it is difficult to use for a flat folded plate roof (a roof covered with a metal plate or the like) as it is. Furthermore, since the dimensions are determined, there is a problem that the size and weight are not necessarily suitable for transportation and storage.

JP 2006-12777 A

In the example shown in Patent Document 1 exemplified above, it is necessary to adjust the width of the gantry in advance to the width of the solar cell module, and there is a problem that the size of the solar cell module cannot be freely set. .
Moreover, there is a problem that it cannot be installed on a flat roof or a flat folded plate roof as it is.
Furthermore, since the size is determined, there is a problem that it is not necessarily suitable for transportation and storage.

It is an object to realize a pedestal device of a solar power generation apparatus that is suitable for transportation, can be easily connected to each other, and can create a device having a predetermined size.

  In order to solve the above-described problems, a mounting device for a solar power generation device according to the present invention is a mounting device for a solar power generation device that forms a solar cell module for a solar power generation device by holding a side surface of a solar cell panel. In addition, at least two crosspiece members are provided, and hinge mechanisms capable of adjusting the angle are provided in at least two places between the crosspiece members.

  Here, a fixing member for fixing the gantry device is attached to a rail-shaped base beam member which is one of the beam members, and when fixing on a flat roof, an adhesive is applied only to the back surface of the fixing member. It is characterized by bonding and fixing.

  In addition, the rail-like base beam member of the beam members has left and right ends extending in a bowl shape. Bolt fixing holes are provided in the bowl-shaped portion, and the metal surface such as a folded plate roof is provided. When fixing, bolts are fixed using this hole.

  Further, the plurality of crosspiece members are folded by the hinge mechanism and folded together.

  Furthermore, a rail-shaped base crosspiece member of the crosspiece members is extended, and the extension portion can be connected to the base crosspiece member of another gantry device in the front-rear direction.

  Since the gantry device of the present invention is configured as described above, the side surface of the solar cell panel is held as the gantry device of the solar power generation device, and the solar cell panel is maintained at a predetermined angle with respect to the solar rays. Power generation can be improved and is not limited to the size of the module. It can be installed on a flat roof or a flat folded-plate roof as it is, suitable for storage and transportation, and interconnected. Can be realized.
