Abstract: The present invention refers to an anchorage for underpinning and bearing walls. The anchorage includes at least one head module and a brace tube which are joined coaxially together. The head module has a tapered point which serves as a guide and in the proximity to this point, the head module has at least two foldable blades on both sides of the brace tube. The blades present reinforcement ribs and tabs on their outer part and they are joined at one of their ends to the brace tube with a joint hinge and held at an upper third of the blades by a clamping device which is linked to the brace tube with a removable bolt. This removable bolt includes a knuckle pin with an end linked by a connector to the brace tube. The opposite end includes a clearance drilling angled at a slant, at 45 degrees of its axle, this end being inserted in the brace tube in correspondence with a bolt clamp.
