EARTH ANCHOR BRACKET HAVING SAW-TOOTHED AND CURVED PART

摘要

THE PRESENT INVENTION PROVIDES AN EARTH ANCHOR BRACKET (100) SUPPORTED BY A GIRDER (4) COUPLED TO A SIDE SURFACE OF AN EARTH WALL (1) TO FIX A FREE LENGTH OF AN ANCHOR BODY (3) INSERTED INTO A BORING HOLE FORMED AT THE EARTH WALL (1) ACCORDING TO AN EARTH ANCHOR METHOD. THE EARTH ANCHOR BRACKET (100) OF THE PRESENT INVENTION INCLUDES TWO SIDE PLATES (110) EACH INCLUDING A CURVED PORTION (114) INCLUDING SAW-TEETH (115) AND FACING EACH OTHER; A COUPLING MATERIAL (120) COUPLING AND FIXING THE TWO SIDE PLATES (110); AND A PRESSURE BEARING MEANS SUPPORTED BY THE TWO SIDE PLATES (110) AND INCLUDING OBSTACLE PROTRUSIONS ENGAGED (134) WITH THE SAW-TEETH (115) OF THE TWO SIDE PLATES (110) AND A THROUGH PORTION (132) WITHDRAWING THE FREE LENGTH OF THE ANCHOR BODY (3). ACCORDING TO THE PRESENT INVENTION, BECAUSE THE CURVED PORTION (114) INCLUDING THE SAW-TEETH (115) IS FORMED AT THE SIDE PLATE OF THE EARTH ANCHOR BRACKET (100), EVEN THOUGH A POSITION OF A BORING PORTION TO INSERT THE ANCHOR BODY (3) IS DEVIATED SOMEWHAT FROM A RIGHT POSITION, THE PRESSURE BEARING MEANS BEARING THE TENSION FORCE OF THE ANCHOR BODY (3) CAN BE PREVENTED MOVING. FURTHER, BECAUSE THE PRESSURE RESISTING ABILITY IS FURTHER IMPROVED THAN THAT OF THE PRIOR ART, LIGHTENING AND MINIATURIZING THE EARTH ANCHOR CAN BE SOUGHT COMPARED TO THE PRIOR ART WITH RESPECT TO THE SAME TENSION FORCE.
