(Cl. 20--1) This invention relates t0 »framework formed of relatively light planks of wood or other material, and the primary object of the invention is to pro vide frameworks of this character of larger size and greater strength than have heretofore been available, by associating the planks in a novel manner under tension. ` ` Other important objects and advantages of the invention will be apparent in the following de scription and the accompanying drawings, where in for purposes of illustration only, preferred em bodiments of the invention are set forth. In the drawings: 2 I 2 being oppositely angulated to receive the twisted ends and thereby hold the transverse members 9 in their twisted condition. The ten sion exerted by the twisted cross members 9 on the planks I0 and II stresses these planks and hence the entire framework, and thereby the framework’has rigidity and resistance to distor tion by outside stress substantially greater it would otherwise have with the component ele 10 ments not under internal stress.` Flooring can be made by placing on the frame work of the type illustrated in Figure 2, a frame I3,.on which is then spread a concrete beton I4 which clings to the frame and enters the per 15 forations Iliathereof. A coating I5 completes the readiness of the frame I4 to receive the Figure 2 is a fragmentary perspective view parquet, brick or`~`other flooring on its upper showing an embodiment of the present invention part, while its lower part is ready to receive Figure l is a perspective view of a plank show ing it twisted to endow it with tension in accord ance with the present invention. in a framework for supporting flooring or the the elements I6, such as reeds or laths which like. 20 can support a coating, forming the airspaces B Figure 3 is a sectional and elevational View between this coating and the flooring I5, the on a reduced scale showing completion of floor coated `elements IS forming the ceiling for the ing on a framework of the type shown in Figure 2. neXt lower story or the like, Figure 4 is a fragmentary perspective view of Referring now to Figures 4 and 5 of the draw an embodiment of the invention in heavy frame ings, showing heavy lframework in accordance work of curved construction, and, with the present invention, in a curved form, Figure 5 is a group perspective view partly in and utilizing the construction shown in Figure 3, elevation and partly diagrammatic, of construc there are present the framing |261., light mortar tions of different sizes utilizing the type of frame Il', and a tight coating I8, and the interior pan work illustrated in Figure 4, and partly broken 30 els I 9 oi cork, laminated wood, agglomerates or away to show structural details. other materials suited to the particular use for It is well known that planks of such material which the building is intended. as young green wood react strongly when placed The framework of the present invention can be under tension by twisting them, and that the re satisfactorily made from >fresh cut green young sultant tension endows the planks with very sub wood. Also, if desired, in the constructions shown stantial strength and resistance to other stresses in Figures 2 and 3, the framing B may be when assembled in such tensioned condition, omitted and the airspaces B taken up by some which the planks would not have in their ordi porous filling leaving the wood free to breathe, nary state of rest. Because of these phenomena, in which cases the flooring I5 and the ceiling I iind it possible to provide larger and stronger 40 forming elements I6 are ñXed directly to the frameworks constructed from planks of much beams I0 and II. lighter than usual material and of smaller than An important feature of the invention »is that usual cross section, through assembling the planks units such as shown in Figure 2 of the draw under tension as disclosed herein. ings made be standardized and made portable, so The embodiment of the invention shown in 45 >that they can be readily transported to the job Figure 2 of the drawings, is a framework for and be set up by the workmen, the joining of supporting flooring or the like, consisting of at the required assemblies being easily effected by least one joist or the like 9a with at least two means of bolts or the like. In the arrangement longitudinal laterally spaced members each com of Figures 4 and 5, the wall plates 20 and ridge posed of planks I0 and Il, with their ends rig 50 poles ZI may be in sections accommodating one ’ idly connected as at 9b to the joist, and with or more of the building units described herein transverse members 9 having their opposite ends , above. It will be apparent that the present in anchored, as in saw slots I2 cut in the planks, - ~ « vention is readily adaptable for the construction the transverse members 9 being longitudinally twisted as indicated in Figure 1, and the saw slots and lining of such buildings as tunnels, silos, bins and the like. 2,414,094 3 I claim: 1.
