PROBLEM TO BE SOLVED: To provide a pressure support frame for a ground anchor securing the ground contact area with the ground, reliably holding the ground, having a simplified and lightweight structure easily assembled from a split state, mitigating installation conditions due to easy carry-in to a site, and reducing cost for the labor and the whole anchor work. SOLUTION: A plurality of nearly frame-shaped pressing sections 3 are integrally fitted to a nearly box-shaped core section 2, and prescribed expansive bodies 4 stored in the opening portions of the pressing sections 3 are expanded to be closely stuck to the ground 50. An anchor tensile member 10 is fixed to the core section 2 in this state, the holding area of the ground 50 is fully secured by the pressing sections 3, and the expansive bodies 4 are closely stuck to irregular portions on the surface of the ground 50 to reliably hold the ground 50. A site for integral assembling can be optionally selected, the core section 2 and the pressing sections 3 can be carried-in in the split state, and this pressure receiving frame is adaptable to various places.
