Abstract

A construction packer comprising a base part including a base shim and a wall component extending substantially perpendicular to the base shim, the wall component having a first interlocking feature; and a stacking shim configured to be placed on top of the base shim and having a second interlocking feature provided at an edge thereof that engages with the first interlocking feature to provide an assembled construction packer.

Claims (15)

1 . A construction packer comprising a base part including a base shim and a wall component extending substantially perpendicular to the base shim, the wall component having a first interlocking feature; and

a stacking shim configured to be placed on top of the base shim and having a second interlocking feature provided at an edge thereof that engages with the first interlocking feature to provide an assembled construction packer;

wherein the first interlocking feature is a slot and the second interlocking feature is a detent that engages with the slot, wherein the detent has a resilient width that narrows when forced through the slot and widens once through the slot to prevent removal from the slot.

2 . The construction packer claimed in claim 1 , wherein the first interlocking feature is configured to receive multiple second interlocking features corresponding to multiple stacking shims stacked one on top of the other and engaged with the base part.

3 . The construction packer claimed in claim 1 , wherein the slot is open from a juncture between the base shim and the wall component and extends along the wall component away from the juncture.

4 . The construction packer claimed in claim 1 , wherein the length of the slot defines a stacking guide for receiving one or more stacking shims.

5 . The construction packer claimed in claim 1 , wherein the first interlocking feature comprises two parallel slots in the wall component.

6 . The construction packer claimed in claim 1 , wherein the detent is specifically an anchoring clip that protrudes from a side edge of the stacking shim.

7 . The construction packer claimed in claim 1 , wherein the detent comprises two spaced apart fingers each capped with an outward facing retaining lip, wherein the fingers are resiliently movable toward each other and the lips prevent the detent removing from the slot.

8 . The construction packer claimed in claim 1 , wherein the number of second interlocking features is equal to the number of first interlocking features.

9 . The construction packer claimed in claim 1 , wherein the wall component extends from the base shim at a right angle.

10 . The construction packer claimed in claim 1 , wherein the base shim is provided with an obstacle recess for accommodating building hardware.

11 . The construction packer claimed in claim 1 , wherein the stacking shim is colour-coded according to its thickness.

12 . The construction packer claimed in claim 1 , wherein the base part and stacking shim are made of a thermoplastic.

13 . The construction packer claimed in claim 6 , wherein the anchoring clip protrudes from the side edge in the same plane as the stacking shim.
