FIXED LOAD SUPPORT MEMBER

Japanese Patent JP3859609

B2

PROBLEM TO BE SOLVED: To provide a fixed load support member incorporated with a horizontal directional shearing deformation restricting wall for eliminating micro-displacement in the horizontal direction of an upper support member by ordinary traffic vibration by a wheel load such as a truck, in its turn, eliminating micro-displacement in the horizontal direction of an upper structure such as a beam.
SOLUTION: This load support member is used for an elastic support device for a structure, and makes the upper support member 3 and a lower support member 2 relatively horizontally immovable by restricting shearing deformation of an elastic layer 5 by the shearing deformation restricting wall 4. The shearing deformation restricting wall 4 is integrally arranged in any one member of the lower support member 2 or the upper support member 3. The shearing deformation restricting wall 4 is arranged in the elastic layer 5 so as to project toward any other member of the lower support member 2 or the upper support member 3. A tip part of the shearing deformation restricting wall 4 is slidably fitted to a recessed part 9 arranged in the other member.
