PROBLEM TO BE SOLVED: To provide a thin slide support device for construction which is simple in structure, reduced in the number of part items, thinned in the thickness of a support, and easy in installation and replacement work.SOLUTION: A thin slide support device comprises: a base plate 5 fixed to a lower structure 2 such as a foundation; a support holding member 6 detachably fixed to the base plate with an installation bolt 20 and formed with a hollow support holding part 8; a rubber layer 12 having steel plates 13, 14 at upper and lower faces formed below the support holding part and expandable to a side face; a lower-part slide member 16 which is arranged on the rubber layer of the support holding part and installed with a low-friction material 17 at its upper part, and whose upper end is protruded upward from the upper face of the support holding member; and an upper-part slide member 18 which is fixed to the side of an upper structure 3 and forms a slide face by contacting with the lower-part slide member. A penetration hole or a recess 15 is formed at least at one face of the upper and lower plates with which a flat part of the rubber layer contacts, and the elastic deformation of the rubber layer caused by stress is absorbed by the swelling of the side face of the rubber layer and the swelling of the flat part of the rubber layer to the penetration hole or the recess. |
