Definitions

  • This invention relates to an anchor which may be imbedded into a concrete slab and to which fittings may be secured.
  • the invention will be described by way of example in relation to its use in a concrete wall but it should be appreciated that this is by way of example only and the slab may be a floor or ceiling.
  • wall slabs are either cast in situ or prefabricated and there is a need for attaching fittings such as steel framework or the like to the wall to allow the building to be constructed.
  • Anchors of a variety of types are imbedded into the slab by being positioned and fixed relative to reinforcement prior to the pouring of the concrete for making the slab.
  • a face of the anchor is located against formwork used in the slab construction. Once the slab has cured the formwork may be removed to expose the anchors to have fittings to be secured to them.
  • anchors be accurately positioned at desired locations in the resultant slab. Some anchors are able to be adjusted so that slight misalignment or mis-positioning can be tolerated.
  • an anchor for imbedding into a concrete slab and to which fittings may be secured having:
  • the housing may have any desired peripheral shape and has at least one peripheral wall.
  • the housing may have a circular peripheral shape and the peripheral wall may be substantially cylindrical although this is not essential.
  • the housing has a base opening and an access opening spaced from the base opening.
  • the access opening is formed by a return wall projecting inwardly from the or each peripheral wall.
  • the return wall may have an annular appearance.
  • the housing may have at least one anchor portion for allowing the housing to be secured to reinforcement normally forming part of the slab in which it is embedded.
  • two anchor portions are present.
  • the anchor portions may comprise lugs extending outwardly of the housing. Where the housing has a circular peripheral wall, the lugs may extend outwardly from the wall at diametrically spaced locations on the wall.
  • the anchor includes a cover.
  • the cover normally seals the base opening of the housing.
  • the cover is preferably formed as a part separate from the housing and is fitted to the housing to close off the base opening.
  • the cover, where the peripheral wall of the housing is circular is also circular in shape and has an outwardly extending flange which may locate relative to the housing.
  • the flange is received within the housing and closely adjacent an inner surface of the peripheral wall of the housing.
  • the cover preferably has two concentric part cylindrical flanges which receive the wall of the housing between them.
  • the cover has a main panel from which the flanges may extend. If desired, one or more spacing projection may be present on the panel and located inwardly of the inner most flange. The or each spacing projection serve to the carriage support slightly from the main panel of the cover.
  • the anchor has a cap which is located relative to the housing and adjacent the access opening.
  • the cap is located within the housing and partially closes off the access opening. It is preferred that the cap has a lip which locates relative to the underside of the return wall.
  • the cap preferably has a slot extending part way across it.
  • the slot may have arcuate ends although this is not necessary.
  • the anchor has a carriage support.
  • the support may have spaced upstanding opposed side flanges for receiving the fastener carriage and for guiding movement of the fastener carriage across the support.
  • Preferably the support is substantially U shaped and has a wall extending between the opposed side flanges. The way may have a slot.
  • the fastener carriage may be substantially U shaped with a connecting wall and opposed side arms. Outer faces of the side arms may be shaped or have flat profiles for engaging the opposed flanges of the carriage support. In this way the fastener carriage is free to move along the support but is held against rotation relative to the support by the opposed flanges on the support.
  • the support may be provided by outwardly projecting flanges extending from the cap and towards the fastener carriage.
  • the carriage support in this embodiment is formed integrally with the cap. Preferably two diametrically opposed flanges are present.
  • the carriage support is formed as a discrete component.
  • the support when provided as a discrete component, has locating members for engagement with the cap to ensure that the cap, the support and the fastener carriage held between them may rotate as a unit within the housing.
  • the locating members are present as fingers projecting from the flanges on the support and the cap is provided with locating recesses for receiving the fingers. If desired, fingers may project from the cap and the flanges may have locating recesses.
  • the fastener is received by the fastener carriage and is held against rotation relative to the fastener carriage.
  • the fastener is a threaded nut.
  • the fastener carriage has an aperture through which a bolt may project to mate with the nut.
  • the fastener may be a bolt with the head of the bolt being received between the side arms of the fastener carriage and held against rotation and with the shank of the bolt extending outwardly through the aperture in the fastener carriage.
  • FIG. 1 is a perspective view of an anchor according to an embodiment of the invention.
  • FIG. 2 is an exploded view of the anchor of FIG. 1 ;
  • FIG. 3 is an exploded view of an anchor according to another embodiment of the invention.
  • the anchor 10 has a cylindrical body 12 with an annular inwardly directed return wall 11 defining an access opening 15 .
  • the opposite end of the body is open.
  • Anchor portions 13 , 14 project outwardly from diametrically opposed locations of the body 12 .
  • the anchor 10 includes a cap 20 , a fastener carriage 30 , a fastener 40 , a carriage support 50 and a cover 60 .
  • the cap 20 has raised portions 23 , 24 which are received within opening 15 .
  • a flange or lip 26 extends around the portions 23 , 24 and prevents the cap 20 from passing through the opening 15 .
  • a channel 22 is present between portions 23 , 24 and a slot 21 is located within the channel 22 .
  • the cap 20 has recesses 25 formed in the lip 26 . Four such recesses are present arranged in pairs on opposed sides of the cap.
  • Fastener carriage 30 is U shaped and has a connecting wall with an aperture 31 extending through it.
  • the carriage 30 has legs 33 , 34 with outer flattened faces.
  • the carriage 30 has a cavity 32 for receiving fastener 40 in such a way that it prevents rotation of the fastener 40 relative to the carriage 30 .
  • Carriage support 50 has side flanges 52 and 53 extending from a connecting wall 57 .
  • the flattened sides of legs 33 , 34 engage against the inner surfaces of flanges 52 and 53 , such that the carriage is free to move along the support 50 but cannot rotate relative to it.
  • a slot 51 is formed in the wall 57 .
  • the support 50 has fingers 54 and 55 which project from the flanges 52 , 53 and engage with recesses 25 in the cap 20 so that in the assembled condition the cap 20 retains the carriage 30 and the fastener 40 between it and the support 50 as a unit free to rotate within the body 12 .
