A method for linking foundation belt at reinforcement of existing belt foundation system with a new foundation plate includes arrangement in the body of the foundation belt, normally to its long axis, with given separation in horizontal direction, of separate horizontal console reinforced-concrete beams with circular cross sections, those at leaving the body of the foundation belt are connected to each other with a horizontal tie reinforced-concrete bean, this at one side adjoins the foundation belt, and at the other side is connected to the foundation plate. The console beams are arranged as some section at inlet to the body of the foundation belt with diameter larger compared to the last section, this provides increase of area of contact of beams with material of belt foundation just in zone of largest concentration of compression stresses, and in the end zone, where compression stresses with opposite sign occur, after concreting the beams and concrete coming to designed strength through tubes laid in the body of console beams injection with cement mortar to material of belt foundation is performed, this increases the area of contact of the beams with strengthening material of foundation belt in the zone of contact with the console beams along with that. |
