The invention discloses a support structure for improving the adaptability of buildings to the ground, comprising a base, two left and right symmetrical mounting blocks are fixedly connected to the left and right sides of the base, and a first mounting plate is fixedly connected to the inner wall of the bottom of the base . The present invention plays the role of supporting the building by arranging the first mounting plate, the ball, the second mounting plate and the supporting plate, and also plays the role of fixing the supporting plate by arranging the positioning plate and the positioning bolt. When the situation is complicated, the upper surface of the support plate is inclined. By adjusting the upper surface of the support plate to the level, the support plate is completely fixed by the positioning bolts, and then the support plate can be kept in a horizontal state even in the case of complicated ground conditions, so as to achieve the support The board has the proper supporting effect to ensure the stability of the building above, thereby making the entire building safer.
