TEMPORARY GATE, INSTALLATION STRUCTURE FOR TEMPORARY GATE, AND PILE STRUCTURE FOR INSTALLING TEMPORARY FENCE/GATE

摘要

A temporary gate, an installation structure for a temporary gate, and a pile structure for installing a temporary fence/gate are provided with: base plates which are respectively affixed to the lower portions of the gate posts of the temporary gate; and spiral piles which are respectively inserted through and affixed to the plate surfaces of the base plates, are extended downward relative to the base plates, and are embedded within the installation surfaces. Each of the spiral piles is configured integrally from: a twisted plate which has a twisted shape and which is spirally extended about an extension axis; and an affixation bar which is extended on the extension axis from the center of the upper end of the twisted plate. Each of the base plates is horizontally gripped and affixed by plate affixing devices which grip the base plate from the upper and lower surface sides thereof. The configuration eliminates the need of embedding a concrete foundation in the ground and stably maintains the vertically supported position of a heavy object having a moment load. Therefore, the configuration is suitable for frequent movement and for supporting a large temporary structure. Also, the configuration enables the position of installation to be changed after the piles are installed, and enables repeated use.
