  • Patent number: 10132070
    Abstract: A flexible modular trench includes an open-faced channel extending along a central axis between a pair of axial ends. The open-faced channel includes a pair of axially-extending shelves connected by a trench wall. The trench wall has a smooth inner surface and a corrugated outer surface. The corrugated outer surface has corrugations extending along a plane perpendicular to the central axis to allow for increased flexibility such that the flexible modular trench is bendable in a direction perpendicular to the central axis.

  • Patent number: 10017933
    Abstract: An elongate linear drain for a shower includes an elongate, channel-shaped drain body, an elongate, channel-shaped extension that is connectable to either end of the drain body, elongate inserts that are nested within the drain body and the extension, and end walls that cap the ends of the drain body and the ends of the extension. Mounting members are formed along an outboard side of each sidewall of the drain body and the extensions and the mounting members are engaged by float sticks to facilitate the sloping of the floor that leads to the linear drain. Height adjustment screws formed in the respective bottom walls of the drain body and extensions enable height adjustment of the inserts. This enables the tile that overlies the shower floor to be flush with the tile that overlies the insert.

  • Patent number: 9834894
    Abstract: A drainage installation (20), for a warehouse and/or factory floor that has a surface level (26), has a drainage channel (24) recessed into the floor and a plurality of sections of flat grating (22) seated inside the drainage channel (24). The drainage channel (24) has an axially-elongated, square-U shaped channel portion which is flanked by horizontal shoulders (30), which then transition into vertically-depending skirt portions (32). The horizontal shoulders (30) as well as the sections of flat grating (22) are arranged to be more less planar with the surface level (26). Wherein, the skirt portions (32) are formed with a series of apertures (36) which either allow the injection of wet cement underneath the shoulder portions (30) of the drainage channel (24), or alternately the venting of the wet cement when the cavity under the shoulder portions (30) are over-filled.

  • Patent number: 8211298
    Abstract: A method of manufacturing a cast article including a frame that in use of the article defines an aperture; and a further component that is in use retained moveably captive relative to the frame. The method casts the further component and respective first and second frame members, the further component and the frame members being securable together to form the article, and subsequently assembles the frame members and the further component together to form the article. A gully grate results from practicing the method.

  • Publication number: 20120107044
    Abstract: A grating system provides enhanced see through characteristics and typically includes longitudinal deep bars, axial crossbars, axial filler bars between the crossbars and longitudinal joining bars which join the crossbars and filler bars to one another. The deep bars are part of a first subassembly and the other bars are part of a second subassembly which may be lowered to join the two subassemblies to one another. The crossbars and filler bars are typically seated on the deep bars. The joining bars are typically above and aligned with the deep bars. The upper surfaces of the crossbars and filler bars are usually substantially flush with one another. The grating system is configured to support vehicular and pedestrian traffic.

  • Patent number: 8122674
    Abstract: A grating system typically includes longitudinal deep bars, axial crossbars, longitudinal filler bars seated on the crossbars between the deep bars and axial joining bars which join the deep bars and filler bars to one another. The crossbars are inserted lengthwise through slots formed in the deep bars. The joining bars are inserted lengthwise into holes formed in the deep bars and filler bars. The joining bars are typically above and aligned with the crossbars. The upper surfaces of the crossbars and filler bars are substantially flush with one another to form most of the upper surface of the grating system on which vehicular and pedestrian traffic typically travel.

  • Patent number: 8075219
    Abstract: An improved grate 601 is made from a plurality of elongate grate pieces 602, each grate piece 602 having a body 603 with a first end 604 and a second end 605. Each grate piece 602 has the first end 604 angled with respect to the body 603 and the second end 605 angled with respect to the body 603. When the first end 604 of a grate piece 602a is welded to the first end of an adjacent grate piece 602b, and the second end 605 of the grate piece 602a is welded to the second end of the adjacent grate piece 602b so as to form the grate 601, a gap is formed between the respective bodies of the grate pieces 602 to permit the drainage of liquid between the grate pieces. By varying the angles at which the grate pieces 602 are welded together sections of grate with both horizontal and vertical curvature can be formed.

  • Patent number: 7967523
    Abstract: A trench drain assembly including a flow channel and a frame for supporting the channel in a trench. Sidewalls of the frame have a gradually increasing height between ends of the frame so that the frame creates a gradual slope for the assembly to properly drain. In addition, sidewalls of the frame include spaced lugs that extend outwardly and sidewalls of the channel include spaced lugs that extend inwardly to create an interference fit with the lugs of the frame so that the channel can be easily attached to the frame. During assembly, the frame is lowered onto the channel so that the lugs of the frame are received between the lugs of the channels and the frame is then slid with respect to the channel until the lugs of the frame are positioned below the lugs of the channel to secure the frame to the channel.
