PROVISIONAL SPECIFICATION.
Improvements in Combined Timber and Concrete Walling, Flooring,
and Roofing.
GEORGE EDWARD CLARE, Architect and Surveyor, 66, Duke Street, Chelmsford
Essex, do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in the construction of combined fireproof
timber and concrete walls, floors, and roofs for buildings and the like.
Hitherto difficulties have been experienced in the construction of concrete
work, as for instance
(1) The use of complicated and costly apparatus to keep it true and rigid.
(2) The cost of skilled labour, accustomed to the work.
(3) The danger of unequal settlement shrinkage and cracking of large surfaces
wholly composed of concrete.
The object of my invention is to render the construction of concrete walls,
floors and roofs, perfectly simple, by the insertion of timber framework, rendered
fireproof and damp-proof, so as to comply with the bye laws of the Local Govern-
ment Board and at the same time be cheaper than ordinary solid concrete.
brick or stone work, and by the use of breeze or similar couerete, to admit of
the surfaces being finished with, tiling, slating, boarding and the like being
nailed to the same, or coated with any form of plastering, or left plain for
cheaper class of buildings.
To carry out my invention, the walls, floors or roofs, would first be constructed
of open timber framework, the timbers being sawn to a special section or left
square, and fillets nailed on to form a key for the concrete.
The timbers used would be of non-inflamable wood, and rendered damp proof
when exposed on the outside.
After the framework is erected the spaces between the timbers, would be
filled in with coke breeze, clinker or other concrete, by means of sections of
removeable battening secured to the timbers.
And where hollow walls, floors, or roofs are required for exposed positions, the
concrete would be built up in two thicknesses bonded together, and with a cavity
between.

ascertained in and by the following statement ;-
-
My invention relates to improvements in the construction of combined fireproof
timber and concrete walls, floors and roofs for buildings and the like.
Hitherto difficulties have been experienced in the construction of concrete work;
as for instance firstly, the use of complicated and costly apparatus to keep it
true and rigid, secondly, the cost of skilled labour accustomed to the work, thirdly,
the danger of unequal settlement shrinkage, and crackling of large surfaces
wholly composed of concreto.
And in order that my invention may be thoroughly understood, I now proceed
to describe the accompanying drawing" thereof, reference being had to letters and
figures marked thereon.
Fig. 1, is an elevation of a portion of a house shewing the construction of
my invention with the framing built up in position and the concrete a filled in
by means of planking that slides vertically in grooved fillets, or otherwise fixed.
Fig 2, is a ground plan of Fig. 1.
Fig. 3, is a vertical section of Fig. 1.
Fig. 4, is a section of a building framed together and laid horizontally on a
prepared level surface, and the concrete filled in the spaces and levelled off
with a straight edge g, after the concrete is set the section would be hoisted into
position; these sections could be prepared anywhere and carted to where required
and placed in a vertical position by the usual tackle; and is more suitable for low
buildings such as one storey bungalows.
Fig. 5, is an enlarged and more detailed plan of Fig. 2.
Fig. 6, is an enlarged and more detailed plan of Fig. 4, showing how two
sections can be bolted together at the angles.
Figs. 7, and 8, are enlarged sectional details of Fig. 3.
Fig. 9, is a plan shewing wire netting, expanded metal or the like interlaced
to the framing, and fixed to it to secure concrete to the framing instead of
fillets

m studs forming openings for doors, windows, etc.
n wire netting or the like interlaced to secure concrete to timbers.
and in Fig. 6, shews a simple form of construction where concrete will
be exposed and cover fillets would then be fixed on to each side of tlie vertical
stud to secure the concrete and to cover the joints.
The object of my invention is to render the construction of concrete walls.
floors, and roofs, perfectly simple by the insertion of timber framework rendered
fire proof and damp proof, so as to comply with the byelaws of the Local Govern-
ment, and at the same time be cheaper than ordinary solid concrete, brick or stone
work, and by the use of breeze or similar concrete to admit of the surfaces being
finished with tiling, slating, boarding, or the like. being nailed to the same, or
ocated with any form of plastering, or left plain for cheap class of buildings.

page_text: T'o carry out
my invention the walls, floors, or roofs, would first be constructed
of open timber framework, the timber being sawn to a special section or left
square, and fillets nailed on to form a key for the concrete.
The timbers used would be of non-flammable wood, and rendered damp proof
when exposed on the outside.
After the framework is erected the spaces between the timbers would be
filled in with coke breeze, clinker or other concrete, by means of section removable
battening or the like secured to the timbers, and where hollow walls, floors, or
roofs are required for exposed positions the concrete would be built up in two
thicknesses bonded together with a cavity between, or the concrete could be cast
in blocks and fixed between timbers.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:―
1. The combined timber and concrete walling, flooring, and roofing, for the
erection of buildings constructed in the same manner as fully described in the
above specification, and illustrated in the accompanying drawing.
2. In forming a fireproot construction, the combination of the concrete and wire
netting, with the fireproof timbers, substantially as herein described.
3. In combined timber and concrete buildings, the combination of fillets,
vertical studs, angle studs, girts or plates and joists, substantially as herein
described and according to the accompanying drawing.
4. The combination of hollow concrete walls, floors and roofs, substantially as
herein described for the purpose specified.
