13 Claims. (Cl. 154-44)
My invention elates to improvements in lami
nated structured and particularly to improve
ments in such structures wherein a compressible
fragile interior lamination is arranged between
5 two outer protective laminations and provided
with spacers which prevent crushing of the into
rior lamination, and securing devices which ex
tend through the several laminations holding
them together.

An object is to provide such a structure with
improved means to secure the several laminations

spacers to permit limited compression of the

A material which I have found suitable is one
formed of cellulose ?bers very loosely integrated 30
together. It consists of a pluralityof gossamer
like layers of asphalt impregnated cellulose ?bers.
The several layers are held together by the as
phaltic binder. The material is moisture resist
ant in that the cellulose ?bers are coated. with 35
thin ?lms of- asphalt. The material is thermo
plastic and under heat and pressure it may be '
permanently compacted and densi?ed.

For each tubular spacer element I provide a
pair of cooperating split tubular sleeves or fer
rules 22. These sleeves are secured to the outer
protective laminations as shown in Figs. 2 and 3‘
and extend into opposite ends of the spacer ele

with ridges or corrugations which are adapted to
, secure them to the outer laminations I4 and I8
and also to secure them frictionally in place
within the spacer elements and with end ?anges
15 which overlie the outer layers l4 and 18. The
combined length of the two sleeves within any‘
spacer element is less than the axial dimension
of such spacer whereby limited axial compressi
bility of the spacer is permitted before the two
20 ferrules are brought into engagement to- limit
such compressibility.
While the spacer‘ elements are compressible
they are not compressible to the same extent
that the insulation lamination I6 is compressible.
25 The insulation lamination is very easily com—
pressed to a small fraction of, its normal thick
ness while the permitted axial compressibility of
these tubular spacers is relatively slight and
increasingly resisted and the spacer elements are
30 resilient to return the outer walls of the lami
support provided with apertures to receive the
same the worker can see to align-the sleeve aper
tures with the apertures through the support.
Upon this alignment being accomplished the fas
teners may then be inserted in place.
As the expansible heads of the‘ fasteners are
passed through the apertures within the support
they expand su?iciently to engage the support to
secure the panel thereto. This expansion is due
to the inherent expansible tendency of the split
spring fastener.
The spacer elements are com
pressed su?lciently to permit of this‘compression
of the laminated panel against the support. The 15
split sleeves permit limited compression of the
spacer elements while preventing undue com
pression which might result from the.stacking
or storing of a plurality of panels. Such undue
compression if permitted might result in perma 20
nent densi?cation or compacting of the interior
insulation layer as a'result of its thermoplastic.
