Description

  The present invention relates to a panel mount for installing various panels such as solar battery panels at predetermined installation locations such as the ground.

  2. Description of the Related Art Conventionally, for example, those described in Patent Documents 1 and 2 are known as panel mounts for installing a solar cell panel at a predetermined installation location such as the ground or a building rooftop. These solar panel mounts are generally made of concrete foundation pedestals installed on the ground, anchor bolts embedded in the pedestals, and steel frames fastened to the anchor bolts by bolts. And. The concrete pedestal is installed on the ground after leveling the ground at the installation site.

  The frame is a frame body that supports the solar cell panel so that the solar cell panel faces a predetermined direction and altitude, for example, a column that is erected at an interval at an installation location where the solar cell panel is installed And a beam member for connecting the columns. These columns and beam members are connected by a fastener such as a bolt.

The panel mount used can be considered. In this case, for example, the wedge provided at the end of the beam member is fitted into the support member on the support column side, and the solar cell panel is fixed to the beam member.

  However, in such a connection structure, since the operator manually performs the operation of receiving the wedge into the hole of the member using a hammer or the like, there is a possibility that the amount of insertion of the wedge will vary. Further, there is a risk that the worker forgets to drive the wedge to a predetermined driving amount after temporarily fixing the wedge to the member. In particular, in the case of a solar cell panel installed in a large area, if the user forgets to perform a driving operation up to a predetermined driving amount, there is a high possibility that he / she will not notice it later. If the wedge driving amount is insufficient as in these cases, there is a problem that it is difficult to maintain the reliability of the connection strength between the column and the beam member.

  In addition, if the wedge driving amount is insufficient, when the solar cell panel receives wind and buoyancy occurs, the wedge and the receiving member are disengaged from the beam member to which the solar cell panel is fixed. Since the force acts in the direction, it may be difficult to stably fix the solar cell panel.

  The present invention has been made in view of the circumstances as described above, and can easily connect between the support column and the beam member, and can provide a reliable connection strength between the support column and the beam member.
