Resumen
Device for linking existing micropiles and shoes for building enhancement. It is a linking device between foundations to be stressed and micropiles, both of any material. With it the unión between both elements is improved, usually entrusted to the simple friction between the surfaces of both materials. The device has a main part composed of a shaft (1) and pressure shoes (4), temporarily joined together by tying elements (8). Before inserting into the hole made in the foundation (6) to be stressed, a transition element or screw (9) is placed to join the device with the micropile (7). The desired effect of exerting pressure on the walls of the foundation hole to be stressed is achieved by activating the device by means of a screw or pressure rod (3), operated manually or mechanically.
