A wall protecting assembly is provided for protecting outwardly exposed intersecting wall surfaces adjacent the intersection thereof comprising a rigid base plate securely attached to the wall surfaces and overlying an associated corner and a semi-resilient cover member mounted in spaced relation to the base plate. A cushion member projects outwardly from the base plate adjacent the corner so as to cushion impacts administered to the cover member and retains the cover member in spaced apart relationship relative to the base plate. Stop members are utilized to maintain spacing between the base plate and the cover member at locations spaced from the intersection.

A floor grid is provided for a trafficway for removing debris from traffic passing thereover. The grid comprises a support structure below the surface of the trafficway, a plurality of spaced tread rails defining an upper surface which is generally flush with the surface of the trafficway and being supported by the support structure, and a plurality of traverse spacer bars or channels positioned immediately beneath the tread rails. Each tread rail is secured to each spacer channel by a bolt where both cross. Each bolt has a head which is received in and is slidable, when the bolt is not tightened, along a pair of confronting slots in an associated tread rail. Each of the slots has a flat vertical surface which respectively butt against a pair of flat vertical surfaces of the bolt head preventing rotation of the bolt relative to the tread rail. Preferably the slots are just high enough to snugly receive the bolt heads. Feet extend outwardly from the lower end of each tread rail and engage the spacer channels. The feet in conjunction with the tightened bolts resist movement of the tread rail with respect to the spacer channels. The tread rails and spacer channels together form an insert which is easily removable for repair or cleaning. Cushions are provided between the tread rails and support structure to absorb vibration and impact.

An expansion joint filler strip and cover assembly for a joint formed by spaced structural sections includes elongate base members secured to respective structural sections and having a joint therebetween. The base members have spaced apart, upstanding first and second and third walls with the third wall being substantially contiguous with the joint forming wall surface of the respective structural section. The first and second wall portions define an elongate, channel therebetween and the second and third wall portions define an elongate, recess therebetween with the third wall portion terminating in an edge spaced below the terminating edges of the first and second wall portions. A replaceable, elastomeric strip extends across the joint and has side portions secured to the base members with at least one side portion having an elongate flange received within the elongate recess and an outer surface even with the terminating edges of the first and second wall portions. An elongate cover member engaged with the terminating edges of the first and second wall portions and the elastomeric strip. An elongate tongue is received into the channel between the first and second wall portions. Preferably, clips in the channels provide an interference engagement with the first and second wall portions and the cover member tongue for retaining the cover member and the side portion of the elastomeric strip on the respective base member.

A wall protection assembly, for protecting an outwardly projecting corner of a building wall, includes a rigid base member having angularly disposed walls, each terminating in an outwardly extending abutment flange. The corner guard includes a semi-resilient guard member having a wall portion thereof, the wall portion having an inwardly extending flange on each side thereof for engaging the respective abutment flanges on the base member. The base member and guard member have interengaging portions adjacent the side thereof to retain the guard member on the base member with the guard member flanges engaging the abutment flanges of the base member. The abutment flanges contain any displacement or expansion of the guard member resulting from an impact thereto.

A stair nosing structure for a stair step having a tread surface and a riser or forwardly facing surface includes an elongated rigid base member having spaced portions defining at least one channel extending along the length thereof and an elongated tread member having elongated means extending therefrom and into the base member channel or channels with an interference engagement with spaced portions of the base member including at least one face of one of the base member channel defining portions to secure the tread member to the base member.
