Description

  The present invention relates to a fixing device and method for a workpiece or a building using an earth anchor with a rotary bearing member.

A conventional method of fixing to the ground of a building or building is to fix the workpiece or building to the ground gravitationally with a concrete foundation so that the workpiece or building does not fall or move due to an external force such as wind force or seismic force.
In order to connect workpieces etc. to the ground, the earth anchor with rotating support body and the technique of its construction method were proposed. (See Patent Document 1)

Japanese Patent No. 4752046

Due to the accident at the nuclear power plant caused by the Great East Japan Earthquake on March 11, 2011, further use of natural energy has come to be desired. There is a trial calculation that power equivalent to 40 nuclear power plants can be obtained if solar cells are installed in abandoned farmland or abandoned farmland in Japan.
Conventionally, when a solar panel mount is provided on the ground, it has been installed on the ground in a gravitational manner using a concrete foundation. However, it can be imagined that it is cheaper to fix the solar panel mount to the ground using a cheaper earth anchor than to fix it to the ground gravitationally with a concrete foundation. In addition, when the solar battery is installed in a closed land, abandoned farmland, or desert, it is desirable that the solar battery can be easily removed and transferred. In that sense, it is desirable to fix the solar panel mount to the ground using a ground anchor with a rotating support body that can be easily pulled out and reused rather than relying on a gravity foundation. Necessary and sufficient durability and strength can be obtained by using a material such as SUS304 for the earth anchor.
With the technique of patent document 1, the technique which connects a ground workpiece to the ground was proposed. However, it did not show how to fix the work or structure to the ground.
By economically fixing the work and building to the ground, the foundation can be made smaller and the foundation work cost can be reduced. In addition, an application for “earth anchor with rotating support body and its construction method” improved after Patent Document 1 has been filed (see Japanese Patent Application No. 2011-236191).
