[0031] Reference is first made to FIG. 1A, which, in a top view,
illustrated the geometry of an elongated timber or lumber member
according to the invention, for an elongated, thermally insulating
building construction element assembly. In the exemplary end view
of FIG. 1A, the longitudinal axes of the member is generally
perpendicular to the drawing plane. Accordingly, a plurality of
slots 12 running over all part of the length of the member 10, are

depths Y, made in the member of general width W and thickness H.
The elongated timber or lumber member 10 illustrated in FIG. 1A is
also provided with a joining surface 11, generally over the width W
of the member to provide a surface adapted and suitable for
assembling the elongated member to a corresponding elongated member
10. The grooves or slots 11 formed in the timber or lumber material
16 are made to a depth Y which typically is more than one half of
the thickness H. For the purpose of aligning first and second
elongated members 10 with respective adjoining surfaces 11 facing

15B will take the place of the tongue 15A, thereby also allowing
assembly of a pair of identical elongated timber or lumber members
10 according to the invention to be assembled to form an elongated
thermally isolating building construction element assembly by use
of separate tongue members that would fit into grooves 15B made in
the adjoining surface 11.
[0032] Also illustrated in FIG. 1A is the fitting surface 13
adapted for providing a suitable interface between a further

the elongated, thermally insulating building construction element
assembly.
[0035] FIG. 3 illustrates yet another embodiment of the elongated
member 10, having three grooves or slots 12 formed therein, in a
sectional view, wherein a pair of the elongated members 10 have
been assembled to form the elongated, thermally insulating building
construction element 20. In the embodiment example illustrated in
FIG. 3 the grooves or slots 12 are shaped and positioned in the
longitudinal member 10, such that when a pair of the longitudinal
members 10 are assembled as shown in FIG. 3 to form the
longitudinal, thermally insulating building construction element
assembly 20, the openings formed by the slots or grooves 12 in the
adjoining surface 11 are only partly overlapping as indicated by
P.
[0036] Reference is now made to FIG. 4, which shows in a sectional
view corresponding to the sectional views of FIGS. 1B, 2 and 3, a

building construction element assembly 20 by applying a glue or
cement to all or parts of the adjoining surfaces 11, or by shaping
the tongues 15A and grooves 15B in such a way that they lock to
each other by forcing the elongated timber or lumber members
together from a position indicated in FIG. 5 to a position of
complete assembly as indicated in FIG. 7, and also as indicated in
the sectional views of the complete assembly of the elongated,
thermally insulating building construction element of FIGS. 9 and
10.
[0040] A further embodiment of the elongated, thermally insulating
building construction element illustrated in FIG. 7, is illustrated
in a prospective view in FIG. 8. In FIG. 8 the openings 17 are
provided with respective extensions 17A to provide a through hole
to the building construction element 20, adapted for receiving a
bolt or other means for keeping the longitudinal timber or lumber
members 10 assembled. In FIG. 8 is also shown in phantom

illustrated in FIG. 8, and also illustrating assembly of the
elongated timber or lumber members 10 into the elongated, thermally
insulating building construction element assembly 20 by way of a
bolt 30. Although the illustrations of FIGS. 8 and 9 for sake of
simplicity only illustrate a single set of openings 17 and opening
extensions 17A aligned with each other to accommodate the bolt 30
shown in FIG. 9, the elongated timber or lumber member 10 may be

FIG. 11A illustrate how the construction element assembly 20 is
provided with a cut out or recess 19 adapted to receive the upper
part of the ground beam 40, which, as illustrated in FIG. 11A, also
serves to seal off the slots or grooves 12 at one end of the
building construction element assembly 20. Correspondingly, the
building construction element 20 may be adapted with corresponding
cut out or recess on its other end, i.e., on its upper end in the
wall construction of which a lower part is illustrated in FIG. 11A,
so as to provide a ceiling of the slots or grooves 12 at the upper
end of the building construction element 20. It should be noted
that in the view of FIG. 11A, slots or grooves 12 would actually
not be visible, in that they are located in the interior of the
building construction element 20 and mostly sealed off for
providing means for thermal insulation of the elongated, lumber or
timber thermally insulating building construction element 20. In
the view of FIG. 11A, however, fitting surface 13 would be visible,
as well as the tongue 14A and groove 14B.
[0044] In FIG. 11B is shown the same elements, and in the same
view, as in FIG. 11A, however, in FIG. 11B is shown an embodiment
of the ground beam 40, having cut outs or recesses 41 running in
the ground beam 40 in a direction perpendicular to the drawing
plane, for providing a duct for ventilating one or more of the
grooves or slots in the interior of the building construction
element 20. Although the embodiment of the ground beam illustrated
in FIG. 11B is provided with two cut outs or recesses 41 to serve
as ducts for ventilation, the ground beam 40 may be provided only
with a single cut out or recess 41, or any other numbers of cut
outs or recesses 41, positioned with respect to the grooves or
slots 12 in the interior of the building construction element 20,
so at to provide ventilation of one or more of the slots or grooves
12 as required according to the intended purpose. As an example,
referring again to FIG. 11B, the duct provided by the recess 41 on
the right hand side of the drawing could be feeding hot air that is
driven through the entire length of the building construction
element 20 to its upper end for communicating the air driven
through the slot or groove 12 to a channel or duct provided in a
corresponding top plate.
