Improvements in the Method of and Means for Constructing Floors,
Walls, Partitions, and the like.
We, HUGH LUPUS CUNNAH and HENRY ARTHUR HUGHES, of 11, Queen Victoria
Street, in the City and County of London, Manufacturers, do hereby declare the
nature of this invention and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :-
The objects of this invention are to enable floors, walls, ceilings and the like to
be constructed without the aid of temporary centering used to support the concrete
and plaster before it is set, and to enable walls, partitions and the like to be erected
in a cheap and simple manner.
These objects we obtain by making the foundation or support of the plastic
material (fireproof or otherwise) of corrugated dovetailed and perforated metal such
as steel or iron or of any other suitable material.
And in order that our said invention may be fully understood we will proceed to
explain the same with reference to the accompanying drawings in which
Fig. 1 shews a portion of a perforated sheet ready for corrugation.
Fig. 2 is section of same.
Fig. 3 represents a portion of the same sheet after corrugation.
Fig. 4 is section of same.
Fig. 5 shews a portion of a wall constructed according to this invention.
Fig. 6 shews a portion of a floor also constructed according to this invention.
The same letters denote the same parts in all the Figs.
a is a sheet of metal or other suitable material punched through from each side
at b in such a manner as to leave the perforated portions projecting beyond the level
of the sheet (see Figs. 1 and 2).
The perforated sheet is then by means of suitable machinery corrugated as shown
at Figs. 3 and 4 forming dovetailed keys for the concrete, plaster or cement of which
the wall, partition, floor, ceiling or the like is composed.
Partitions or walls may be rapidly and substantially built with the aid of the
perforated and corrugated sheets as follows
The framework of the wall or partition is made of I or channel iron or steel
uprights c maintained in their proper position by being secured to channel iron or
steel sills & at the top and bottom the said uprights being erected at convenient
distances apart varying from 1 foot to 4 feet and the corrugated sheets with the
corrugations horizontal are lowered into the uprights before the top channel iron or
steel is fixed.
In cases where the sheets cannot be lowered into position from above the head
sill and one upright are placed in position and secured the perforated corrugated
sheets are then inserted sideways into the groove in the upright, dropped into
the sill d and the next upright placed in position and secured and so on, sufficient
space being left to allow of the last sheet passing the flange of the last channel
iron. The whole of the wall or partition thus formed is then filled in on both
sides with a suitable plastic material such as Portland Cement one part, coke
breeze four parts, and. plastered in the usual way, the wall or partition when

page_text: completed being only about two inches thick and sound damp fire and vermin
proof. In some cases the sheets may be imbedded in the plastic material of
which the wall or partition is composed before being placed in position the
various sections being cemented together and afterwards plastered over.
For floors and ceilings the perforated and corrugated sheets f are laid on the lower
flanges of the steel joists g and the space between the sheets and the top of the
joists filled in with concrete h.
The underside of the sheet may be filled in with plaster or merely painted no
temporary centering being required during the construction of the floor.
The perforated and corrugated sheets may be used instead of ordinary lathing for
making ceilings and the like.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed we declare that what
we claim is :-
1. The improved method of and means for constructing walls, ceilings, floors,
partitions and the like which consists in imbedding perforated and corrugated
sheets of metal or other suitable material in concrete or other suitable plastic
material substantially as and for the purpose specified.
2. In the construction of floors, ceilings, walls, partitions and the like the
corrugated and perforated sheets as herein before specified.
3. In the construction of floors, ceilings, walls, partitions and the like the
combination of corrugated perforated sheets with a metal framework of I or
channel iron or steel and concrete cement or other plastic material substantially as
specified.
