Definitions

  • This invention relates to a channel member assembly.
  • Channel members are used in the building industry as anchorages embedded in concrete, so that on setting of the concrete the channel can receive the head of a tee-headed bolt, to the screw-threaded shank of which is then secured items of machinery, brackets or other fittings.
  • the channel member In order to embed the channel member in the concrete it is necessary to mask the channel against the ingress of the fluid concrete, and to secure the channel member to shuttering defining the desired form of the concrete. At present, the channel is provided with holes in its base, and through these the member is nailed to the shuttering.
  • a securing method does not provide full rigidity of the channel member on the shuttering, and after the concrete has cured and the shuttering removed the nails remain extending into the channel and have to be broken, or bent along the base of the channel, to provide access for the tee-headed bolt.
  • a channel member assembly wich comprises a moulding which is inserted into a channel member and which may be removed after concrete has hardened around the channel member and moulding.
  • the moulding forms a groove in the concrete which enables a square headed bolt to be inserted into the channel member via the groove.
  • the moulding disclosed in DE-B-2,916,005 is not rigidly connected to the channel member as it must be removed later to allow insertion of the bolt.
  • a channel member assembly comprising a channel member which comprises two substantially parallel side walls joined by a base portion, the free end of each side wall having a flange, the flanges defining an opening between them; and characterised in that the flanges are inturned to be directed substantially parallel to said side wall of the channel member, and in that the assembly further comprises a bracket comprising securing means to allow the securement of the assembly to shuttering, and projection means engaged with the channel member between each side wall and respective flange to connect the bracket rigidly to the channel member.
  • the bracket is generally in the form of a plate and said projection means extend from a face of the plate.
  • the bracket does not protrude into the opening for the channel defined by the flanges.
  • the bracket is engageable with an end portion of the channel member thereby to provide a closure for said end portion during pouring of the concrete.
  • the bracket is in the form of a plate which provides the closure.
  • the means for allowing securement to the shuttering is provided by a through hole in the bracket for passage of a nail which will secure the bracket and the channel member to the shuttering.
  • the through hole is directed so as to be normal to the base of the channel in use.
  • a bracket 1 is generally rectangular in front view (Fig. 1) and is formed from 4 mm thick polypropylene.
  • a side wall 2 extends from three sides of the bracket 1, its inner corners 4 being radiussed to correspond to the radius of the base of a channel member on which it is to fit.
  • An apertured boss 6 is integrally formed along a portion of the side wall 2, and a through bore 8 within the boss 6 extends parallel to the side portion of the side wall 2.
  • the through bore 8 has four projections 9 which each have a tapered end 11, which is recessed within the bore 8 adjacent the top end 7 of the boss 6.
  • the four projections 9 extend from the tapered ends 11, along the inside of the bore 8 to a base 13 of the boss 6.
  • the bracket 1 has a generally rectangular gap 10 defined by its rear and side walls, and a tang 12 projects from the side wall 2 into the gap 10.
  • the lower edge of the gap 10 as defined by the rear wall has a further resilient lip 14 extending inwardly of the bracket 1.
  • a pair of projections 16 of rectangular cross-section project from a lower part of the rear wall of the bracket inwardly of the bracket 1.
  • the bracket 1 is installed on a channel member 18 as shown in Fig. 5, with a leg 20 of the channel member being threaded through the gap 10 until the bracket fits tightly around an open end face of the channel member and is held thereon by engagement of the bracket on the outer surface of the channel member's wall.
  • the bracket is then held in position by engagement of the tang 12 and the lip 14 with the leg 20, while the projections 16 engage within respective grooves formed along the channel member by virtue of its side walls being bent inwardly and upwardly to provide a retaining face for the tee-headed bolt.
  • the brackets When thus installed, the brackets close off the ends of the channel member to concrete poured into the shuttered volume, and the open channel itself is closed by abutment against the shuttering; the interior of the channel is thus effectively sealed against ingress of concrete, and when the concrete has set the shuttering can be removed by forcing it free of the nails through which it is held to the channel member.
  • the nails are positioned at the ends of the channel member and do not interfere with the function of the channel in receiving a tee-headed bolt slidable along the channel.
  • the position of the apertured boss 6 on a side of the bracket ensures that the channel member is secured to the shuttering at diagonally opposed end locations, thus providing full stability for the fixture.
  • This embodiment of the invention not only avoids the need for deflecting or breaking nails inserted through the base of the channel, but also ensures that the nails are supported within the apertures 8 over a longer distance than with such prior art arrangements, thus providing greater resistance to bending and greater rigidity for the channel member on the shuttering. It also provides for the nails to be supplied already inserted in the aperture 8 and held therein by friction with the aperture wall, thus reducing frustration caused by lack or loss of nails during fitting.
