SPACER FOR FACING PANELS OF CONCRETE WALLS

CALES D'ESPACEMENT POUR PANNEAUX DE PAREMENT POUR MURS DE BETON

English 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.

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.

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.
