Description
Patented Sept. 12, 1944 UNITED STATES PATENT OFFICE.
HEAT-INSULTED FLOOB' Carl. Georg Munters, Stocksund, Sweden Application January 5, 1943, Serial No. 471,344 In Sweden September 8, 1941 4 Claims.
This invention relates to heat-insulated floors, particularly for cold-storage' rooms. ticularly the invention relates to fioors comprising a layer of heat-insulating material placed on a substructure and a layer of concrete lying on top of the first-mentioned layer. said concrete layer being carried by supports extending from the substructure through the insulating layer. The invention has for its main objects to provide a fioor of this type which is inexpensive with respect to the erection cost and which possesses great strength and a good insulating capacity.
Further objects and advantages of the invention will be apparent from the following description considered in connection with the accompanying drawing which forms a part of this specification, and 'of which:
Fig. 1 shows a plan view of a portion of a floor in accordance with the invention, the concrete layer being partly broken away.
Fig. 2 shows a section on the line II-II of Fig. 1.
In the drawing, lfl designates the substructure of a fioor, which may be made from concrete, for example, said substructure having insulation boards or units |2 of the multilayer type provided thereon. Narrow ribs il extending along the fioor are set on edge between the insulation board |2, said ribs bearing with the lower portion thereof on the substructure IO while projecting with theirupper portion for a distance above the boards. The ribs ll, which may consist of a material such as Eternite, carry steel reinforcing rods |6 or the like which are preferably placed crosswise over the surface of the fioor, as will be seen from the drawing. A layer 18 of concrete of a suitable thickness is cast on the insulation units 12, the reinforqing rods IB being thus embedded in their entirety within the concrete so as to reinforce the latter in the usual way. Inasmuch asthe ribs |4 extend above the insulation boards-l2,"the"upper More paralternate corrugated and plane sheets of paper, which are joined to each other by means of waterglass or the like, and which are impregnated with bitmuinous products. Insulation boards of this type have been found to withstand the weight of the concrete layer |8 during pouring and prior to the setting of the latter, without any compression of the boards taking place, which compression would reduce the insulating capacity of the boards. The insulation boards are placed with the corrugations of the sheets extending substantially parallel to the ribs ll. By this arrangement there will be formed open passages along the surface .of the fioor, which may be connected into a circulation system comprising the fioor and wall insu' lation of the cold-storage room as well as the room itself as shown in the copending application 449,240 of C. G. Munters and D. E. Ahlqvist. Two insulation boards 12 lying adiacent one another between two ribs Il may be spaced a small distance from one another, so that an open circulation path for the air will be obtained with certainty even at the transition between the boards.
While a more or less specific embodiment of the invention has been shown, it is to be understood that this is for purpose of illustration only, and that the invention is not to be limited thereby, but its scope is to be determined by the appended claims viewed in the light of the prior art.
What I claim is:
i. A heat insulated fioor comprising a substructure, a plurality of spaced relatively thin rib members set on edge on said substructure, heat insulating material supported on said substructure between said rib members, reinforcends thereof are also cast into the concrete; The
ing rods supported by said rib members, and a layer of concrete on said insulating material and surrounding said reinforcing rods.
2. A heat insulated fioor comprising 'a substructure, a plurality of spaced relatively thin rib members set on edge on said substructure, heat insulating material supported on said substructure between said rib members, the upper said rib members which extend above said insuw lating material.
3. A heat insulated fioor comprising a substructure, a plurality of spaced relatively thin having suiiicient strength to support said concrete during the pouring and setting thereoi! without substantial reduction in the volume of said air spaces.
4. A heat insulated floor comprising a substructure, a piurality of spaced relativeiy thin rib members set on edge on said substructure and multilayer corrugated heat insulating ma- I terial supported on said substructure between said rib member, the corrugation of said material extending substantialiy parallel to said rib members, reinforcing rods supported by said rib member, and a layer of concrete on said insu- 10 lating material and surrounding said reinforcing rods.
