Abstract

ABSTRACT OF THE DISCLOSURE:
A spacer for facing panels of a concrete wall, including a pair of pegs, each having a head to lie against an external surface of a panel and a shank to pass freely through a hole in the panel. The shanks have a series of spaced holes in them so enabling the spacer to be used with different thickness panels, and a link is provided having bent-over ends to pass through holes in the shanks to connect them together. The ends co-operate in use with the heads to grip the panels whereby the spacing of the panels is determined.

Description

Jt;'~

This invention relates to spacers for facing panels of concrete walls, which spacers are of the kind intended to hold the panels in a desired spaced relation prior to filling of the space between them with concrete.
According to this invention there is provided a spacer for facing panels of a concrete wall, which spacer comprises a pair of.pegs, each having a head to lie against an external surface of a panel and a shank to pass freely through a hole in the panel, and a link having bent-over ends to pass :'.
; 10 through holes in the shanks to connect them together, which ends in use are in contact ~ith the inner surfaces of said.
, facing panels and co-~operate with the heads to grip the panels . whereby the spacing of tl,e panels is determined.
~. The shanks may have a series of spaced holes in them .~ so enabling the spacer to be used with different thickness ,: ~
panels.
Furthermore, the shanks may be longitudinally grooved to receive the link whereby the shanks are held aligned and the link is neatly retained.
~, . 20 An embodiment of the inventi.on will now be described, by way of example, with reference to the accompanying drawing in which:--. ; Fig. 1 shows the pegs of a spacer viewed from above and inserted in panels, and Fig. 2 shows in sectional elevation the inserted pegs ... .
d ~ ~ connected by a link.
:~ In .the drawing, a pair o~ panels 1 and 2 for facing a :~: concrete wall are shown prior to filling of the space between :. them with concrete.
~ 30 q'he spacing of the panels is maintained by spacers .. each of which comprises a pair of pegs 3, 4 and a link $.

;'' .- The pegs 39 4, which conveniently are of a plastics , materia],, have flat heads 5, 15 which, when the pegs are inserted in aligned holes 9, 10 in the panels, overlie ,' the outer surfaces o the panels to take the loads applied to the panels during pouring of concrete. The :~1 pegs 3, 4 have shanks which extend through the holes 9, 10 ~,i, O with radial clearance if desired to facilitate insertion.
;. The shanks in the form shown have in them'longitudinally-':~,. spaced holes 6, 7 which open into longitudinal :',1 1 :
grooves 11, 12o ~i , The link'8 i~s for instance of stout iron wire and ~;`. has its ends 13, 14 bent at right angles to the medial '~ ' portion which is of a length dependent on the desired -1 spacing of the panels. After the pegs have been ', inserted through the holes 9, 10, the link 8 is inserted so that it lies in the aligned grooves 11, 12 with ~ts ~'' C ends 13, 14 inserted through the ones of the holes 6, 7 ' adjacent the ilmer surfaces of the panels 1, 2. Thus ! ` the link 8 resists displacement of the panels when ~.
subject to external pressures, the panels fitting neatly ',` 1 ` between the heads 5, 15 and link ends 13, 14.

~',, ' It will be clear that the spacer of this invention .,.,' , not only ensures the correct spacing of the panels, but also'can be easily fitted by relatively unskilled labour `,: without using special tools.

Claims

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:-

1. A spacer for facing panels of a concrete wall, which spacer comprises a pair of pegs, each having a head to lie against an external surface of a panel and a shank to pass freely through a hole in the panel, and a link having bent-over ends to pass through holes in the shanks to connect them together, which ends in use are in contact with the inner surfaces of said facing panels and co-operate with the heads to grip the panels whereby the spacing of the panels is determined.

2. A spacer according to claim 1, wherein the shanks have a series of spaced holes in them so enabling the spacer to be used with different thickness panels.

3. A spacer according to claim 1 or claim 2, wherein the shanks are longitudinally grooved to receive the link.

4. A concrete wall having facing panels spaced apart by spacers as claimed in claim 1 or claim 2.
