9 Claims. (01, -4 3 This invention relates to building elements,,and particularly to structural units for forming partitions. I

One object of the invention is, to provide astruc- 5 tural unit of they type referred to which is of light weight, easy to handle, and capable of being fabricated at a reasonable cost.

Another object of the invention is to provide a structural unit of the type referred towhich is so constructed as to materially reduce reflection of sound from a partition and transmission of sound from one side of a partitionto its other side.

A further objectof the invention is to provide a structural unit of the type referredto which may be readily erected upon the job, and which, moreover, may be taken down intact and re-erected, thus providing a material reduction in cost of material.

A still further object of the invention is to provide a structural unit of the type specified, of such a nature that when a plurality of these units are assembled to form a partition, they will present a structure having a substantially protected continuous rigid metallic core to prevent transmission offire from one side to the other. H H With these objects in view, the in ention consists in an article of manufacture comprising a structural unit and in a partition or the like constructed of such units, each unit comprising a relatively rigid metallic core and sound deadening and absorbing materials applied thereto, and each unit provided with means for interengagement with the units, next adjacent theretoin a structure composed of same, all as will be explained more p ticularly and'flnally claimed. 'j

In the accompanying drawing illustrating the invention, in the several figures of which like parts are similarly s gnated, F gure 1 is air agme tary sectional perspective view of a partition 'con- 40 structed in accordance with the invention and Iormed of the units contemplated by the invention. Fig. 2 is ahorizontal'section through a unit of preferred form. Fig. 3 is a section taken substantially upon the line 3- 3 oi Fig. 2 and illustrating parts of twounits and structural details preferably embodied'therein. Fig. 4 is a tragmentary horizontal sectionshovving the abutting interlocking edges of two units of amodified form of which the invention is susceptible.

Referring particularly to Figs. 1, 2 and 3, each unit includes a continuous: imperforate, sheetmetal core member 1 having appropriately applied to it at one of its longitudinal edges, by welding, riveting or other means, two rigid angle members 2 providing supporting struts, these' members thickness. 7

In forming partitionsoi the units described, an angle member er. the, like 8 isattached by in the upper lateraledges of ,the

gagedandsupported in proper position by. the

being so' arranged relatively to the edge of the coremember 1 as to provide a slot or groove 3 equal to the thickness of member 1. 'Applied to the core thus formed of the core member 1 and angle members 2 is a coating or insulating sound 5 absorbent or deadening material 4 such as a softpofrous mastic-impregnated felt, or felt fiber com bined with a suitablebinder, to which are applied cork boards 5,.or other appropriate material having soundabsorbent or deadening properties preferably differing from those of the mastic coating 4. Asw'ill be seen, particularly by an inspection of Figs. 2' and 3', the sound absorbent or deadening materialsie and 5 terminate sufiiciently short of one longitudinal edgebfthe core member l'to provide an ofistanding tongue 6, for a purpose later explained. It will be noted also that 'the' core member 1 terminates short of one lateral, edge of the u'nit, as indicated at 7,}(Eig. 3) to provide in the upper edge of the unita groove similar to the 'grooveB f" These units are; preferably made' in such lengthsland widths. as to. facilitate their handlin and assembly; For example, they .may be in I lengths of approximately eight and ten feet to 25 accommodate ordinary. ceiling heights, andthey maybe. from nine, to twelve inches wide, and they may be oisuchcross sectionas to permit the use of sound deade'ning materials of appropriate spikeaboltsor screws!) to the ceiling and a plastic ,recei-vingfmember or trough 10, is attached to the floor by spikes, bolts or screws 11. The units are .so' assembled that ,the complemental tongues '6 and. grooves {3 of adjacent units are intereng'aged, as illustrated in Fig. I and the grooves provided units are ohceiling attachedangle member 8. ,AS each unit is. properly positioned, its floor adjacent edge is blocked up or shimmed up into close contact with the ceiling, and after the units are'in'place." the plastic. receivingmember or trough i0 is filled 45 with, plaster ot-'. Paris, cement mortar or other appropriate" plastic which,,when itsets, rigidly maintainsall of the units in adjusted position.

Referring now particularly to Fig.3, it will be ,seen'that one longitudinal edge of thecore 1 of ,50

the unit, is notched out at suitable intervals throughout its length, 'asfin dicated at I3, to receive a, pluralityo'fwedge shaped cutting 1nembars 14 which, when the angles 2 are'riveted to the core member llmay be so spaced as to be held way into the tongues 6, the tendency will be for relative longitudinal movement to takeplace between the adjacent units, and this will, as the units are successively assembled in place, force them successively into close contact with the ceiling. a

It will be apparent from the foregoing, and

from an inspection of Fig. 1, that when the units described are assembled as indicated, to form a partition, the interengagement between the tongue and groove elements of the longitudinal edges of the core members will form in effect a continuous, unbroken, imperforate, metallic diaphragm throughout the partition. It will be noted also, that the angle members 2 provide struts which impart vertical strength to the partition and to the diaphragm'formed by the engaging core members 1. Moreover, due to the arrangement of the sound deadening materials on the cores, these sound deadening materials will completely enclose the cores and struts and will be in close contact throughout the partition and present a substantially unbroken sound deadening surface on each side of the partition.

By employing'themastic coatings 4 and the cork or other layers 5, the twohaving different sound absorbing properties or coeflicients, it will be seen that the sound deadening and absorbing properties of the units and of the partitions formed thereof will be enhanced. For example:Sound waves striking the partition will first be absorbed by the layer 5, and waves not so ab sorbed and passing through this layer will be partially, at least, absorbedin the underlying ad- J'acent coating 4. Any portions of the wave energy which penetrate the coating 4 will "strike against the solid metal diaphragm formed by the cores 1 and will be to some extent reflected back through the coating 4 and layer 5 referred to, but will be substantially absorbed therein. Obviously, sound waves penetrating the layer 5 and coating 4 and striking the diaphragm formed by the cores 1 will to some extent pass through the diaphragm due to the vibration set up therein, but because of the deadening effect produced by their passage through the layer 5 and coating 4 referred to they will not, to any appreciable extent, penetrate the coating 4 and layer 5 upon the opposite side of the diaphragm.

Furthermore, transmission of sound through the partition from floor to ceiling, and vice versa, will be materially reduced, due to the formation of the units and the intimate contact of the sound deadening layers and coatings thereof with the ceiling and the bedding of the lower edges of the units in the plastic mass contained in the member 10.

Although the preferred embodiment of the invention is illustrated in Figs. 1 to 3 inclusive, it is obviTaus that it is susceptibleof modification,

, and one modification is illustrated in Fig. 4. In

this modification, the core members 1' are shown as having one longitudinal edge 17, bent over to angle form and to this part 17 is fixed, by riveting -broken partition-forming; arrangement,

or welding or other suitable means, a channel member 18 which forms a groove to receive the complementally shaped edge 19 of the adjacent unit. In this form of the invention the mastic coating 4 and cork or the like layers 5 are preferably used in the same manner as the corresponding parts 4 and 5 already described.

Due to the construction of the units, the materials of which the layers 5 and 5 are preferably formed, and the intimate flush contact of the exposed surfaces of the units when assembled, it is possible to. so treat these exposed surfaces, preferably during their manufacture, as to provide any desirable ornamental effect to produce an attractive wall surface, without any additional finish.

It will be understood from the foregoing, that it is the intention to produce these structural units in appropriate lengths, widths and thicknesses and of such desired surfacefinishes as to provide an article of manufacture which may be set up upon the job, in the manner described, to produce a finished, attractive partition which needs no further treatment, surface or otherwise, to make it a presentable, sightly structure.

Moreover, due to the structural characteristics and method of assembly of the units, it will be apparent that a partition formed thereof, may, when desired, be taken down without injury to the units, and another partition erected from the same units.

Various changes are contemplated as within the spirit of the invention and the scope of the following claims.
