w 18, W24 y M1156 HARTMANN CEILING Filed All. 20. 1923 Patented Nov. l, llQZd.
OTTO HARTIWANN, F ESSEN, GERMANY.
CEILING.
Application filed August 20, 1923.
To all whom t may concern.'
Be it known that l, O'r'ro HARTMANN, a German citizen, and a resident of Essen, Germany, have invented certain new and useful Improvements in Ceilings, of which the following is a specification.
This invention relates to improvements in ceilings comprising single slabs, for instance of concrete or armoured concrete, forming a continuous surface and supported by lined suspension straps having bent-up ends in engagement with recesses in said slabs, and its novelty consists in providing;n the slabs at their undersides with long grooves in which engage said strap ends at any point thereof and in firmly connecting" the slabs by wires integral therewith and projecting` from the downwardly inclined buttedges of said slabs into the free joints between said slabs formed by said inclined butt-ends, said joints being; then filled out with mortar. rlhe improved ceilinfr is thus almost equivalent `to one large freely suspended ceiling.;` of iron concrete.
In the accompanying drawing: Fig. 1 is a cross-section of part of the ceiling as suspended from a wooden beam, Figs. 2 and il are respectively a plan view and an edge view of the same, Fig. 4 shows a detail of Fig". l on a larger scale.
The slabs a are suspended from ceiling beams Y) by means of suspension straps c oi inverted T shape embracing` said slabs from below and having' on their horizontal members (l bent-up ends e. 'lhe slabs are at their undersides provided with long grooves f in which said ends e are adapted to engage. at any point thereof, so that the straps can be easily and quickly applied, which means an economy of time and work without im- Serial No. 658,390.
pairing'the construction of the ceiling. The underside of the slabs is preferably corrugated, whereby a safe immovable support of the slabs on the suspension straps is ensured as the horizontal members of the latter en gage in the spaces between each two corrugrations. Armouring wires /L are cast in the slabs when moulding the same, in such a way that they project freely from the buttedges of the slabs, which are downwardly inclined or recessed, in such a way that free joints z' open at the top are formed between each two slabs. liy interlacing' the wires L of each two adjacent slabs. the latter are firmly connected. The free joints i are then filled out with mortar.
What l claim, is
l. [i ceiling comprising; single slabs forminga continuous surface and having` long grooves in their undersides, downwardly inclined butt-edges on said slabs forming between said slabs free joints open at the top, fixed suspension straps embracing said slabs from below and having; bent-up ends in engagement with said grooves at any point thereof, and wires integral with said .slabs and freely projecting from said buttfedgjes into said joints, the wires of each two adjarent slabs being` interlaced within said joints, substantially as set forth.
2. ln a ceiling as specified in claim l, a corrugated underside on said slabs, substantially as set forth.
3. In a. ceiling as specified in claim 1, a mortar filling' in said joints, substantially as set forth.
In testimony whereof l have hereunto set my hand.
