Support de poteau

Post support

Abstract

A post (10) and ground support is illustrated utilizing a helical member (B) forming an auger for digging the ground support into the earth, and easily removing the ground support from the ground and re-using said support in another location. The ground support includes a ground engaging stabilizing member (C) affording resistance to a force having a component at right angles to the post (10), and a breakaway connection (D) is provided between the ground support member and the post (10), together with a connection (E) for retaining the post (10) in a position near the ground after separation therefrom. The breakaway connection positions the post (10) upon the ground support above the ground and separates in response to a force coming from any direction about the post (10). A shear pin having longitudinally flat surfaces (92) extending circumferentially thereabout prevents turning of the post with respect to the ground support, and a groove (97) extending about said flat surfaces assure uniformity of shearing from any direction in which the force is applied.
L'invention concerne un poteau (10) et un support en sol utilisant un élément hélicoïdal (B) formant une tarière pour creuser le sol et introduire le support dans la terre, retirer facilement le support du sol et réutiliser ledit support dans un autre emplacement. Ledit support en sol comprend un élément (C) stabilisateur pénétrant dans le sol résistant à une force ayant une composante perpendiculaire au poteau (10). On a prévu un raccordement de rupture (D) entre ledit élément de support en sol et ledit poteau (10), avec un raccordement (E) pour maintenir ledit poteau (10) dans une position proche du sol après sa séparation de celui-ci. Le raccordement de rupture positionne le poteau (10) sur le support en sol au-dessus du sol et se sépare en réaction à une force venant dans n'importe quel sens autour du poteau (10). Une broche de cisaillement autour de laquelle s'étendent des surfaces planes longitudinales (92) empêche que ledit poteau ne tourne par rapport au support de sol, une gorge (97) s'étendant autour desdites surfaces planes assure l'uniformité de cisaillement à partir de n'importe quel sens dans lequel la force est appliquée.
