PROBLEM TO BE SOLVED: To provide a shear force transmission structure that can be formed simply.SOLUTION: A shear force transmission structure 10 has steel plates 11, 12, a connecting bolt 13 and a nut 14, etc. The steel plate 11 is buried over an RC continuous wall 3a and an RC sidewall 4a. The steel plate 12 is buried in the RC sidewall 4a. The steel plates 11, 12 are disposed by aligning the position of holes 112, 122. The shaft of the connecting bolt 13 is inserted into the holes 112, 122, and the nut 14 is tightened on the tip. When an underground structure building frame by the RC sidewall 4a and a bottom slab 5 rises by buoyancy, the steel plate 12 rises and the connecting bolt 13 is pushed up, and rubber ring 131 provided around the shaft is destroyed and locked at the upper part of the hole 112 of the steel plate 11. Thereby, the buoyancy applied to the underground structure building frame is transmitted to the RC continuous wall 3a side as a shear force, and can be resisted by the gravity of the RC continuous wall 3a.SELECTED DRAWING: Figure 2 |
