Adjacent base sections of a base structure of a reciprocating floor conveyor are connected along longitudinal side edges by a tongue and groove joint. Side portions of adjacent sections form a guide beam. The groove and tongue portions of the joint are formed at lower ends of angled inner walls extending downwardly from the top of the guide beam. The inner walls together define an upwardly opening space above the joint. The space is large enough, and the groove and tongue portions are spaced below the top of the guide beam a distance sufficient, to permit the joint to be sealed while maintaining the joint, including sealing portions thereof, isolated from the top of the guide beam and from a bearing positioned on the guide beam. The tongue and groove portions together define a sealing space for receiving a flexible sealant to seal the joint. Sealant oozing out of the sealing space into the space above the joint is isolated from the bearing. The joint may also be secured by a weld bead in the space above the joint. A layer of flexible sealant may be placed on top of the bead. Both the bead and the sealant are isolated from the bearing.
