Description

  The present invention uses a support bolt installed on a foundation structure such as a concrete foundation or a pile foundation, and the solar panel is mounted at a predetermined angle regardless of the inclination of the support bolt due to a construction error of the foundation structure. The present invention relates to a support structure for a solar panel mount that can be installed.

  Conventionally, it is not used as a support structure for a solar panel pedestal, but it is disclosed in Patent Document 1 as a structure that allows rotational deformation of a pillar when a pillar of a building is inclined with respect to a pile foundation due to an earthquake or the like. The disclosed column base connection structure has been proposed.

  In the column base connection structure disclosed in Patent Document 1, a lower support member is attached to a rod-like connection member provided so as to protrude from the head of a steel pipe pile, and the lower end of the column base is formed by the lower support member and the upper pressing member. A flat plate-shaped connecting member attached to is sandwiched and fixed.

  In the column base connection structure disclosed in Patent Document 1, a convex portion is formed on the upper surface of the lower support member, and the lower surface of the upper pressing member is formed with a reduced diameter. By sandwiching a flat plate-like connecting member between the bottom surface of the holding member, it is possible to quantitatively allow the column to rotate and absorb the inclination of the column even if the column of the building is tilted due to an earthquake or the like. It has a structure.

  Here, the column base connection structure disclosed in Patent Document 1 is a structure that can absorb the inclination of the column with respect to the steel pipe pile, but the foundation on which the solar panel is installed can be a foundation structure such as a concrete foundation or a pile foundation. It can also be used as a support structure to be supported by.

JP 2003-55984 A

  However, the column base connection structure disclosed in Patent Document 1 is such that the upper pressing member is fastened to the rod-shaped connecting member, and the connection member is sandwiched between the convex portion of the lower support member and the lower surface of the upper pressing member, In order to absorb the inclination of the column with respect to the steel pipe pile due to the rotational deformation of the column, as shown in FIG. 9 of Patent Document 1, it is necessary to loosen the tightening of the upper pressing member with respect to the connection member.

  For this reason, the column base connection structure disclosed in Patent Document 1 is caused by an earthquake or the like by increasing the range of motion corresponding to the inclination of the column with respect to the steel pipe pile by loosening the tightening of the upper pressing member with respect to the connection member. While it was possible to cope with the inclination, there was a problem that the support of the pillar by the foundation structure might be insufficient.

  Moreover, the column base connection structure disclosed in Patent Document 1 is not based on the assumption that the rod-shaped connecting member and the column are fixed in a relatively inclined state from the beginning when the column is installed on the steel pipe pile. At this time, as shown in FIG. 1 of Patent Document 1, if the rod-like connecting member and the column are not inclined relatively, the convex portion of the lower support member and the flat plate-like shape The connecting member comes into surface contact with each other, and the lower surface of the upper pressing member and the flat connecting member come into surface contact with each other.

  However, the column base connection structure disclosed in Patent Document 1 is shown in Patent Document 1 when the solar panel mount is inclined at a predetermined angle from the horizontal direction in order to improve the power generation efficiency of the solar panel. 9, the rod-shaped connecting member and the column need to be relatively inclined from the beginning, and the flat connecting member is formed by the convex portion of the lower support member and the lower surface of the upper pressing member. Since it will be pinched by the point contact from the up-down direction, there existed a problem that it became difficult to connect with a rod-shaped connection member in the stable support state.

  In addition, in the column base connection structure disclosed in Patent Document 1, a concrete foundation is constructed by the existing uplifted concrete, and when a rod-like connection member provided on the concrete foundation is tilted, a pile is driven into the ground or the like. When a pile foundation is constructed and the rod-shaped connecting member provided on the pile foundation is tilted, the connecting member cannot be freely tilted with respect to the rod-shaped coupling member while maintaining a stable support state. Since the construction error of the connecting member cannot be absorbed, there is a problem that it is difficult to install the solar panel mount at a predetermined angle from the horizontal direction.

  Furthermore, since the solar panel mount must be able to sufficiently resist the weight of the solar panel and the blowing load acting on the solar panel installed outdoors, the convex portion and the upper portion of the lower support member It is necessary to firmly fix the flat connecting member with the lower surface of the pressing member by sandwiching it by surface contact or line contact. However, the column base connection structure disclosed in Patent Document 1 is such that, when the solar panel base is inclined at a predetermined angle from the horizontal direction, as shown in FIG. Since the flat connecting member is sandwiched by point contact between the shape portion and the lower surface of the upper pressing member, there is a problem in that a strong and stable support state cannot be obtained.

  Therefore, the present invention has been devised in view of the above-mentioned problems, and the object of the present invention is to support this even when the support bolt provided on the concrete foundation or the pile foundation is inclined. The solar panel mount can be installed at a predetermined angle by absorbing bolt installation errors, and the solar panel mount can be firmly supported by a concrete foundation or pile foundation.
