BRACKET FOR ANCHOR HEAD ZONE OF DIAPHRAGM WALL

摘要

The present invention relates to a bracket for the anchor head of a diaphragm wall, which has an earth pressure plate of which the pipe bracket can be freely rotated at a random angle according to the angles of tension members in a sleeve when the tension members are extended while passing through the pipe bracket, thereby anchoring the tops of the tension members without the bending of the tension members and actively handling one kind of the sleeve at various angles, wherein the sleeve is constructed at the various angles in the diaphragm wall. According to the present invention, a bracket for the anchor head of a diaphragm wall allows the tops of tension members to be guided and anchored to an anchor head anchoring unit, and comprises: a rectangular earth pressure plate in surface contact with a fixed earth pressure plate arranged on the top of a sleeve, and having a long hole of which the lower side has an arc-shaped holding protrusion protruding therefrom and held on the lower inner surface of the through-hole of the fixed earth pressure plate; a hollow pipe-shaped pipe bracket penetrating the long hole of the earth pressure plate, and installed to be able to be rotated within a predetermined angle range; and two support pins inserted into through-holes in the middles of the pipe bracket, and able to be rotated within the allowable angle range of the long hole by being mounted on the earth pressure plate at both sides of the long hole collinearly, wherein the tension members constructed to be tilted downwards in a drilled hole through the sleeve of the diaphragm wall form an anchor when supported by the wall of the diaphragm wall or the fixed earth pressure plate around the sleeve.
