Formwork spacer and tie used as an anchor for concrete construction
View Patent ↗A device for use with formwork in concrete construction. The device comprising: a body having a bore for defining a first aperture; one or more sidewalls coupled to the body, the sidewalls extending upwardly outwardly with respect to the body; wherein, when the body is releasably coupled to the formwork, the bore is adapted to receive a formwork coupling element. The device can be incorporated into concrete structures within building.
1. A device for use with formwork in concrete construction, the device comprising:
an elongate body having a first end and a second end; a first end surface at the first end of the body having an longitudinally directed bore that defines a first aperture in the first end surface; the bore having a threaded periphery for enabling threaded engagement with a formwork coupling element received axially through the first aperture;
two longitudinal side protrusions, the longitudinal side protrusions being respectively located at opposite sides of the body, each of the side protrusions further defining a sidewall that extends upwardly outwardly with respect to the body for defining a recess there between;
an endwall proximal to the second end of the body; the end-wall interconnects the sidewall of the each side protrusion;
wherein the sidewalls and end-wall have a continuous peripheral outwardly-extending flange; and
wherein, in use, the formwork coupling element is received axially through the first aperture and is threadedly engaged to the bore for releasably coupling the body to the formwork.
2. The device according to claim 1 , further comprising a substantially planar lower base portion for engaging a formwork surface.
3. The device according to claim 2 , further comprising a first fastening element for releasably fastening the device to the formwork surface.
4. The device according to claim 3 , wherein the first fastening element includes a plurality of fixing apertures for receiving nails to releasably fasten the device to a substantially horizontal portion of formwork; the fixing apertures being located in about the body through each of the side protrusions.
5. The device according to claim 1 , in combination with a building comprising concrete, wherein the device is substantially encapsulated in the concrete; and wherein the device can be used as an anchor point when set in concrete.
6. The device according to claim 1 , further comprising a protrusion for abutting engagement with a corner or an edge of formwork.
7. The device according to claim 1 , wherein the bore extends axially into the body and is adapted for threaded engagement with a threaded rod or bolt.
8. The device according to claim 7 , wherein the device further comprising a second aperture at a second end of the body; and the second aperture is adapted for receiving a formwork coupling element.
9. The device according to claim 8 , wherein the bore defines a longitudinal through passage that forms the second aperture.
10. The device according to claim 1 , wherein the bore is a through bore that extends axially through the body for defining a second aperture at the second end of the body, the second aperture being adapted to enable threaded engagement of a second formwork coupling element for releasably coupling the body to the formwork.
11. The device according to claim 8 , further comprising a protrusion for abutting engagement with a corner edge of a formwork.
12. The device according to claim 8 , wherein the device is integrally formed.
13. The device according to claim 12 , wherein the device is constructed from plastics.
14. The device according to claim 10 , wherein the device is constructed from plastics; wherein in use, the device is substantially encapsulated in the concrete with the first end surface exposed to thereby enable the first aperture to define an anchor point in the concrete when set.
