  • the cavity 250 is shaped to prevent the tile support 156 from being removed vertically.
  • the cavity 250 may be a longitudinally extending cavity with a longitudinally extending open slot 256 at a lower end to accommodate the L-shaped plate, but the open slot 256 may be stepped out (i.e. , laterally) from a main body 258 of the cavity 250.
  • the cavity 250 may include a lower shoulder 260 below the main body 258 of the cavity to prevent vertical movement of the first leg 252 within the cavity 250.
  • the tile edging apparatus 240 includes a plurality of the tile supports 156.
  • the tile support 156 may be independent from one another.
  • the plurality of tile supports 156 may be held in a common cavity 250.
  • the longitudinally extending cavity 250 may hold two or more tile supports 156 end to end or spaced from one another along the longitudinal axis 184.
  • the tile edging apparatus 240 may include a connector 270.
  • the connector 270 joins the tile edging apparatus 240 end to end with an another of the tile edging apparatus 240.
  • the connector 270 may be a connector tab.
  • the connector 240 may be a plate slidable into the cavity 250 at one end (e.g., the first end 186) of one tile edging apparatus 240 and into the cavity 250 at an opposite end (e.g., the second end 186) of another tile edging apparatus 240 to join the two tile edging apparatus together.
  • edge restraint 1150 is similar in some respects to edge restraint 150, and like features are indicated by like reference numbers incremented by 1000.
  • the edge restraint 1150 includes a fixation flange 1182.
  • the fixation flange 1182 includes a blocking body 1280 moveable between a secured position over the aperture 1226 and a removed position spaced from the aperture 1226 such that a fastener 1152 can be passed through the aperture 1226.
  • an upper rim 1282 of the aperture 1226 is recessed below a top surface 1284 of the fixation flange 1182.
  • the fixation flange 1182 may include a spaced-apart pair of parallel ridges 1286 flanking the aperture 1226 and spaced from the aperture 1226 to receive a head 1288 of the fastener between the ridges 1286.
  • the ridges 1286 may provide a surface on which tile or other material can rest without resting on the head 1288 of the fastener 1152.
  • each ridge may include a groove 1290 facing the other ridge.
  • the blocking body 1280 may be slidably received in the grooves 1290 between the ridges 1286, the body 1280 overlying the aperture 1226 as exemplified in Figure 12B.
  • the wording “and/or” is intended to represent an inclusive - or. That is, “X and/or Y” is intended to mean X or Y or both, for example. As a further example, “X, Y, and/or Z” is intended to mean X or Y or Z or any combination thereof.

Abstract

Un système de pavage comprend une couche de base ; une couche de sable de sable angulaire grossier au-dessus de la couche de base ; une couche de carreaux de carreaux de porcelaine au-dessus de la couche de sable ; et un dispositif de retenue de bord métallique implanté le long d'un bord de la surface pavée. La couche de base peut comprendre une grille d'armature. Un dispositif de bordage de carreaux comprend une bande de retenue de bord de carreau allongée présentant un axe longitudinal s'étendant entre une première extrémité et une seconde extrémité et un axe vertical s'étendant perpendiculairement à l'axe longitudinal et entre une extrémité supérieure et une extrémité inférieure ; une saillie de fixation s'étendant hors d'un premier côté latéral de la bande de retenue de bord, la saillie de fixation comprenant une ouverture s'étendant généralement verticalement à travers cette dernière ; et une saillie de support de carreau s'étendant hors d'un second côté latéral de la bande de retenue de bord opposée au premier côté latéral, la saillie de support de carreau comprenant une surface de support de carreau.
