11 Claims.

This application is a division of my cepending lapplication Serial No. 221,780, filed September 24, 1927, (Patent No. 1,825,346, issued September 29, 1931) and the invention herein described and claimed relates to materials for building construction, and is particularly applicable tothe construction of floors, ceilings, roofs, Walls and partitions, Where non-combustibility and sound proofness combined with light Weightv are desirable.

The invention aims to provide a light, strong, heat and sound proof fire-resisting slab which may be put in place With facility and does not require plastering to make an acceptable nish.

Further objects of the invention appear hereinafter in connection with the description of the several embodiments illustrated in the accompanying drawings, wherein Y Fig. 1 is a perspective view'of a Wall embodying the invention, showing the'various steps or stages in erection;

Fig. 2 is a cross-section through a ceiling slab at right angles to the direction of the reinforcing strips, showing several varieties of reinforcing and nailing strips suitable for supporting a floor having a Wood iinish;

Fig. 3 is a similar view of a roof slab having a ycement or composition nish; l I

Fig. 4 is a horizontal cross-section through an outside wallv embodying the invention showing a preferred form of stud construction;

Figs. 5 and 6 are similar views illustrating other forms of stud construction; and

vFig. 7 is`a perspective View of a supporting sheet and stiffening bars ready to be placed in a horizontal supporting frame and receive the aerated gysum or similar plastic material to form a slab.

This invention is illustrated in Fig. l as applied to an inside Wall supported uponA floors carried by light Weight beams 11, the iioor slabs 12 being composed of heat and sound insulating material from two to three inches or more in thickness and provided with Wood screeds or nailing strips 13 for a Wood iioor 14, as is customary in apartments and oices and other buildings having this type of floor. Any type of floor construction may be used with partition walls embodying the invention, as it is adapted to both re proof and semi-fire proof or re resisting construction.

In the floor illustrated, the floor slab 12 is composed of suitable re resisting sheets or boards 15, such as sheet rock, gypsum boards, etc., commonly used for partitions and ceilings, which (Cl. 'Y2-16) are laid across the supporting beams 11 and insulate them from the floor slab as described in my Patents Nos. 1,582,172 and 1,582,173, dated April 27, 1926, and which in turn support the door filling 16 of light `Weight heat and sound insulating material, as described in my Patent No. 1,717,444 dated June 18, 1929.

The floor supporting sheets 15 are preferably stiffened to give them sufficient strength and rigidity to support the filling 16 during construction by ribs or bars 17, of Wood or metal, which are secured flat `against the floor Sheets for their entire length by means of suitable adhesive 18, such as asphaltum` or other sticky non-combustible material, that retains its adhesive properties for an indenite period. These bars17-may be made the full depth of the iill and used to support the oor iinish 14 in Wooden floors, or they may be shalloWer and covered by the fill, as desired. `Compositeribs 19 of wood and metal may be usedto advantage, as illustrated in Fig. 2.

Fastening the strengthening ribs to the sheets in the manner described stops the vibration in the ribs so that soun'd will not be'conducted through them, thereby eliminating any direct means for conductingsounds from the room above to the room below or vice versa.

Any suitable means `for protecting the beams may be attached to the under side of the oor. For example, as shown in Fig. 1, the beam protection is alforded by cast concrete channels 20, which may be secured to the under side of the floor slab 12 by means of metal straps or hangers 21 embedded in the channels and having their upper ends projecting through the sheets 15 and anchored by any suitable means.

The wall slabs or filling-in panels 22 (see Figs. 1 and 4) are held at top and bottom by soffit boards 23, which may be secured beneath the beam covering by means of hangers or screws 24, and sills or plates 25, which may be laid along the floor upon the nailing strips Where it is desired to erect a partition. The sills 25 are advantageously secured in position upon the nailing strips 13 or floor slab 12 by means of asphalt or other adhesive.

The wall slabs 22 preferably are precast or made up in advance and stored to harden and dry out thoroughly before being erected in their places in the structure, particularly if made of a wet material like cellular gypsum. In the form illustrated they comprise outer layers 26 of plaster board, sheet rock, or the like, between which is a lling 27 of cellular gypsum, or other heat and sound insulating material. The edges of the their edges to the opposite sides of stiffening strips of rigid material, and a lling of light weight plastic heat and sound insulating material enclosed by said strips and lling the space between said sheets, the outer side edges of said strips projecting beyond the edges of said facing sheets and being shaped or adapted for engagement with similar shaped or adapted side edges of adjoining slabs in the structure to form putty receiving open joints.

7. A substantially rigid heat and sound proof light-weight filling-in panel for attachment to a supporting frame in the construction of Walls, partitions or roofs, consisting of a preformed slab comprising sheet-like insulating material having all its edges secured to and stiifened by strips of rigid material forming with said sheet like material a shallow box-like structure substantially closed except at the side opposite said sheet-likematerial, and a filling of light weight plastic heat and sound insulating material embraced by said sheet-like material and said strips and filling the box-like structure formed thereby substantially flush with the tops of said strips.

8. A substantially rigid heat and sound proof light-weight filling-in panel for attachment to a supporting frame in the construction of walls, partitions or roofs, consisting of a preformed slab comprising facing sheets of insulating material secured at their edges to the opposite sides of stiifening strips of rigid material forming with said sheets of insulating material a shallow boxlike structure substantially closed on all sides, and a lling of light weight plastic heat and sound insulating material entirely filling the space Within said shallow box-like structure.

9. A substantially rigid heat and sound proof light-weight filling-in" panel for attachment to a supporting frame in the construction of walls, partitions or roofs, consisting of a preformed slab comprising a sheet of facing material having its edges secured to and stiffened by strips or" rigid material, and a filling of light weight plastic heat and sound insulating material filling the space enclosed by said strips.

10. A substantially rigid heat and sound proof light-weight filling-in panel for attachment to a supporting frame in the construction of Walls, partitions or roofs, consisting of a preformed slab comprising sheets of facing material secured at their edges to the opposite sides of stiffening strips of rigid material forming with said sheets a shallow box-like structure substantially closed on all sides, and a filling of light Weight plastic heat and sound insulating material iilling the space within said shallow box-like structure.

11. A substantially rigid heat and sound proof light-weight lling-in panel for attachment to a supporting frame in the construction of walls, partitions or roofs, consisting of a preformed slab comprising a sheet of facing material having its edges secured to and stiiened by strips of substantially rigid material, additional stiffem'ng strip means secured to said sheet within the space defined by said edge stiffening strips and of less height than the latter, and a filling of lightweight plastic heat and sound insulating material filling the space within said edge stiffening strips and embedding said additional stiffening strip means.
