Improvements in and relating to the Fastening of Floors and
Ceilings on or to I Irons.
1, PETER SINZIG, Architect, of Hansaring 33, Cologue, in the Empire of
Germany, 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 :--
In the annexed drawing,
Fig. 1 shows the cross-section of a floor and ceiling attached to and carried by
I irons. is the cross-section of an I iron. Longitudinally, that is, parallelly on
the flange is arranged a wood-bar c, which must always have the same width as the
flange, but can be of any height. This bar c is then fixed on the flange of the
I iron at distances of about 50 to 60 cm. alternately on the right and on the left
side by means of my double angle-cramps d. As the under side of the Hange
increases in thickness towards the web, the double angle-cramps d draw the bar c
strongly down upon the flange and as the cramps d are, as hefore mentioned, arranged
alternately, this fastening is excellent and displacement of the bar c from the I iron
is impossible.
The bar may also be put together in pieces of any length. The position of the
iron rail can now be planed or made horizontal by means of the wood-bar e like
any other wooden beam. Then I fix on this bar c, by means of nails, pins or
screws b, any kind of floors a óf wooden planks, cement or gypsum plates.
Fig. 1 shows further on its under part the similar fastening of the bar with
the cramps d for the purpose of arranging ceilings of wooden boards, wood
panelling, cement or gypsum plates, and lath-ceilings of any kind.
Fig. 2 shows the same arrangement as described in Fig. 1 only with the
difference that the wood-bar e is fixed in any thickness, even to the thickness
of a beam, by means of relatively strengthened double angle-cramps d. Otherwise
the construction of the cramps remains unchanged. In the under part of Fig. 2 is
shown the fastening of the bar with the cramps d for the purpose of arranging.
ceilings of wire-fabrics, of reeds or of iron plates of any kind.
Figs. 3 and 4 show my double angle-cramps d. They can be made of square
iron, of wire or of strong band iron with any number of points and teeth.
This cranip consists of the rib d, which at the upper and the under part is bent
nearly rectangularly in the same direction. Whilst the upper bending ends in one
or more wedge-like points, the teeth of the under bending are blunt.
Fig. 5 shows on a reduced scale in plan a floor fixed on the I irons by means of
wood-bars and cramps.
Fig. 6 shows on a reduced scale the cross-section of an arched beton-floor and
ceiling as in Fig. 1.
Figs. 7 and 8 show on a reduced scale a cross-section and longitudinal section of
a beton-floor and ceiling in which the floor arranged on the woud-bar is laid either
with groove and tongue or overlapping edges. Under the I irons is shown a fence
ath ceiling the ends of which can be seen.
From the drawings and description it will be seen that the object of my inven-
tion, that is, the arrangement and fastening of Hoors and ceilings on I irons by
means of wood-bars and double angle cramps, is capable of wide application and
27

page_text: advantage. Whilst hitherto a wood flooring could be arranged on a framing of
I irons only by means of interlying masonry blocks my invention simplifies and
facilitates considerably the production of such a flooring. The system is to be
preferred to all other direct crampings on I irons, because in this invention I can
1) level.the flooring as with any timber joists or construction, which possibility is
completely excluded in all the other, methods: and 2) I can fix the flooring by
means of nails or screws as in any timber supports. In fixing ceilings there is the
same advantage since I can fix (exactly like the floorings) by means of the wood-
bar and the double angle crainps, fence laths, panelling etc. directly on the iron
framing as if to timber framing. In this invention also the weight and the support
load of the floor rests directly on the I iron, whilst by using masonry blocks on
beton the said weight must be taken by the beton vaulting.
Having now particularly described and ascertained the nature of this inven-
tiou and in what manner the same is to be performed I declare that what I
claim is ;-
The arrangement and fastening of floors and ceilings of any kind on or under
I irons by means of parallel bars of any thickness resting longitudinally on the
upper flange or under the lower flange of the I irons, and secured thereto by double
angle cramps with one or more points and teeth.
