Sept. 25, 1934. M. G. CLARK HEATING SYSTEM FOR METAL BUILDING 'Filed April 6, 1931 2 sheets-sneerh INVENTOR a number of angle irons 7 immediately above and below the floor and secured therewith and with the ribs 3 of the walls as by welding. 'Ihe floor is, therefore, in effect rigidly integral with the walls. The structure may of course have any number of floors, one being shown.

It will be apparent that the floor has a number of hollows 9 one between each pair of webs 6, coextensive with the floor, and these hollows are open-ended. Also the structure of the walls provides vertically extending channels between the ribs 3 thereof, of which channels riser conduits 10 may be made by securing metal panel plates 8 over any pair of ribs 3 as by welding. As the hollows 9 open only at two sides of the oor, panel plates 8 are only useful to serve a floor at those sides thereof. If the panel plates extend only above and below a iloor, the hollows 9 of'the latter will obviously be in communicating relation with the risers 10 of the Walls. If a partition 1l be placed across one of the conduit risers at the top of a floor as inFig. 4, all flow between riser and hollow must be to or from below the floor. But if instead a panel plate 8 be laid above the floor the corresponding riser will extend thereabove as to serve another higher oor while still communicating with the rst floor. Thus as indicated in Figs. 1 and 2. a pair of closure members 12 are laid as indicated to provide manifolds extending along below the floor at the edges adjacent the open ends of the hollows 9 thereof, A hot air furnace 13 has delivery connection as by the pipe 14 with one of these manifolds and return connection from the other by way of the pipe 15 and blower 16. There is communication between the inlet manifold and all of the hollows 9 of the floor shown throughout the entire length of the wall. As indicated Fig. 4, partitions 11 are placed between some of the ribs 3 of the corresponding wall just above the floor level so that ow is positively directed into the floor. On other parts of the wall, however, instead plates 8 are employed above the floor to form risers leading above the floor level and to the next floor. On the opposite wall the arrangement is the same.

Thus aV continuous passage for the heating medium is supplied by the furnace 13 across both floors in parallel relation, up one wall, through, and down the other wall therefrom, returning to the furnace by way of the blower.

To improve thermal efficiency, appearance, and acoustical properties the metal of the structure is covered with a non-metallic insulating material as indicated. Wall channel portions which are not used for heating conduits, are lled with this' material as at 17 in an amount sufficient that some of theyrnaterial overlies the plates 8 as at 18 to present a smooth interior wall surface. A thickness of the material as at 19 is applied to the outside Wall surface, as `is a ceiling thickness beneath the floor indicated at 20. The floor is overlaid by a denser` material as at 21.

It will thus be apparent that a closed path is provided for the heating medium which path includes all of the floor areas and part of the wall areas. The conduit dimensions, therefore, while slight in one direction, are so extensive in the other that the sectional area for path of flowis ample 4for all conditions. Moreover, no room space is taken up by any part of the heating system. While air may be employed as the primary medium of heat transfer, this air is recirculated in a closed path so that impurities from the outside are not introduced into the inside thereby.

The arrangement described will be recognized as more or less elementary. In many instances as where heat is to be delivered through a single oor, it is desirable to provide a devious path through the oor. An arrangement for this purpose is shown Figs. 5 and 6 wherein air is introduced into one end of one of the end hollows of the oor as at 22 and return connection is had at one end of the hollow at the opposite end of the floor as at 23. The other ends of the hollows are closed by partitions 24. Openings 2-5 are provided in the webs 6 of the floor. The openings may be located at opposite ends of alternate webs as indicated in Fig. 5, so that the path of flow through the floor will be as shown by the arrows.

Frequently the building structure will include an inside wall 26 between outside walls 27 as indicated in Figs. 7 and 8. Here it is preferable that the heating risers be associated with the inside wall and the return risers with the outside Walls so that the direction of flow will be as indicated by the arrows in Fig. 8. Fig. 9 shows a manner of supporting the inside wall which permits introduction of air thereto entirely therealong. 28 is a beam upon which the inside wall is supported, the wall having the rst adjacent floor level slightly above the eam. At one end of the w'all as at 29 the ribs 3 thereof are turned to the right as appears in Fig. 9 so that by a short closure member 12a a path may be had from the manifold provided into the floor portion toward the right. At the other end of the vwall as at 12b the ribs are turned in the other direction and the manifold 12b similarly provides for introduction of heating air to the left-hand floor portion. 'I'he two floor portions have outlets at 30 and their webs 6 have openings 25 so that flow through the floor portions will be as indicated by the arrows in Fig. 7 and the arrangement will provide a devious path generally similar to that Figs. 5 and 6.

By the employment of panel plates 8 as directed in connection with Figs. 1 and 2, provision may be made for heating additional overhead floors in a manner which will be apparent.

What I claim 15:.

Building construction of the class described comprising a sheet metal floor panel, the panel comprising a plurality of sheet metal units of coextensive length assembled to provide a continuous repeated box section having spaced top and bottom faces with webs extending therebetween, a wall panel at the end of said floor panel and comprising a sheet metal part secured with said floor panel and deformed to provide vertically extending channels opening toward said floor panel and there communicating with cavities ofthe latter, said wall panel including nonmetallic parts overlaid upon said sheet metal parts to close said channels on the corresponding side of said floor panel and thereby provide conduit passage means effective to conduct a heating medium between the hollows of said panels.
