ABSTRACT:
A crosspiece supporting pad in a structural construction member including a resilient member having concavely curved surfaces on its upper and lower sides, and a pair of rigid members each having a convexly curved surface which mates with the concavely curved surfaces of the resilient member. The rigid members are respectively fixed to the upper and lower sides of the resilient member with their convexly curved surfaces respectively held in mating relation with the concavely curved surfaces of the resilient member. The pad has sufficient strength to support a crosspiece in expansion joints and adequately absorbs displacement occuring at the ends of the crosspiece due to a live load and further restrains compressive deformation due to the live load.
