C. T. IVIcFARLANDIA BUILDING CONSTRUCTION.- APPucATloN man nem. 191,3.
Patented Jan. 22, 1918 CLRENCE T. MCFARLAND, OF BOSTON, MASSACHUSETTS.
BUILDING CONSTRUCTION.
Application led December 8, 1913.
To all whom t may concern.'
Be it known that 1, CLARENCE T. MCFAR- LAND, a citizen of the United States, residing in Boston, county of Suolk, and State of Massachusetts, have invented an 1mprovement in Building Constructions, of Which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.
This invention relates to a composite building construction and more particularly to the floors and ceilings of the same.
The inventionis adapted to be embodied in buildings having brick and like outside Walls, and is particularly adapted to be embodied in buildings having Wooden frames.
The invention has for its object to provide a superior floor construction With which a Wooden, brick or like building may be provided With a light Weight metal floor, which is continuous from Wall to Wall, and serves as a lire stop and also to render the building rat and vermin proof, as Will be described.
lThe improved floor construction also enables a material saving in the height and cost of the building to be effected Without sacrificing head room between the different floors, as Will be described.
These and Other features of this invention will be pointed out in the claims at the end of this specification.
Figure l represents a sutlicient portion of a building embodying this invention to enable it to be understood.
Fig. 2, a section of the building shown in Fig. l taken on the line 2 2.
,'Fig. 3, a section 0n the line 3-3 Fig. 1.
F ig. 4, a perspective of the floor plates shown in Fig. 2 inverted.
Fig. 5, an enlarged detail to be referred to, and f Fig. 6, a detail of a reinforcement to be referred to.
In the present instance, 1 have shown the invention as embodied in a building having one side Wall a of brick or like material, and the opposite side Wall o of Wood, With an intermediate partition cap c supported upon post (Z.
1n accordance With this invention, the
Specification of Letters Patent.
Patented Jan. 22, 1.191%.
serial No. 805,382.
outside Walls e, b and the partition cap o, support a sheet metal floor structure preferably of the construction herein shown, and comprising a plurality of sheet metal beams c, and connecting plate members j". The sheet metal beams c may and preferably will be made of the cross section herein shown, see Fig. and consisting of side Walls and a connecting Wall. The side Walls are composed, as herein shown, of converging members or sections 10, and diverging members or sections 12, which extend from the converging members l0, and from which extend the floor members the converging memberslO being connected by the wall let, which forms a substantially Wide bearing for the beam. 1t is preferred to make the members 10 of the side walls materially longer or larger than the members 12.
A plurality' of the hollow sheet metal beams c may be rolled, pressed up or otherwise formed from a fiat metal sheet, with floor members 7I connecting the side Walls of adjacent beams. In the present instance the floor is made up of tivo halves or members each comprising three metal sheets. one of which is provided with four metal beams and each of the other tivo with three metal beams. A floor of sheet metal is thus formed, which comprises a plurality of sheet metal beams and one or more con-- necting plates and adjacent licor sheets may have their adjacent floor members secured together, which may be effected in any suitable manner but preferably by providing said floor members with bent flanges or lips 17, Whichl are capable of being interlocked with unskilled labor on the job after the manner shoivn in Figs. 2 and 5, so as to make a continuous floor sheet extended in one direction of the building, as for instance in the direction of the length thereof from one end Wall 9,0 to the other end Wall 21, see Fig. 2.
The floor sheets may be arranged as herein shovvn, so that the beams of the said sheets extend transversely of the building, as representedrin Figs, 1 and 3, and in the present instance tivo floor sheets are employed to cover the space between the walls a, b, and each floor sheet has one end of its beams resting on one of the side Walls a, o,
and its other end on the partition cap c, and the beams of one of the Hoor sheets are contracted so as to dovetail into the beams of the other floor sheet supported by the partition cap, as clearly shown in Fig. l. In this manner the building is provided with a practically continuous sheet metal floor eX- tended from one side wall as a to the vother side wall 5 of the building and from one end wall 20, to the other end wall 2l and is supported by saidside and end walls. The floor members f of the Hoor sheetsmay be provided with upturned lips 2st, which serve as anchoring devices to secure the floor sheets to the side and end walls of the building, see Figs. l, 2 and 3.
The sheet metal iioor may be reinforced by bridging members, which may be of Wood but are preferably of sheet metal and made as herein shown7 each consisting' of a vertical web 30 having top and bottom flanges 31, 32 and end iianges 33, the ends of said sheet metal bridging members being shaped to conform to the shape of the sides l0, l2 of the beams, so that the bridging members can be slipped between and be supported by the adjacent sides of two beams, as represented in Figs. l and fl.
The flanges 33 of the bridging members afford a sufliciently broad bearing surf'ace for the bridging members to be maintained inv an upright position without otherwise fastening them to the sheet metal beams.
The sheet metal floor is shown in Fig. l in its normal position, and in Fig. Llin an inverted position, to enable the construction to be clearly shown and understood.
The hollow sheet metal beams may and preferably will have' extended into them, so as to rest upon the diverging members l2 of the side walls of said beams, filler strips or pieces 37 of wood, or other suitable material, which project above the beams and form supports for the floor boa-rds 38,V to which the latter may be nailed or otherwise secured.
The metal beams e may have secured to them wire lathing 39, which may be fastened by tie wires 40, which are passed through holes 4l in the side walls of the beams near the lower edges of the same.
A layer 42 of plaster may be applied to the wire lathing 39 in the usual manner. If desired the side walls 10, 12 of the sheet metal beams may be reinforced by sheet metal shoes lle, see Fig. 6, which are shaped to conform to the shape of the larger portion of the beam, so that the said shoes can be slipped intoor over the beams as desired and fastened in any suitable manner as for instance by spot welding or riveting.
The wooden strips or nailers 37, may be nailed or otherwise secured in fixed relation to the beams, andthey may be `Hush with or project above the beams. The sheet metal Vfrom one another -bers of a greater wi beams may be of less depth than that redrawing, vit will be seen'that the sheet metal floorV runs from wall to wall and over artition ca s thereby eliminating thenecessity for the usual fire stopping', and making the building practically ratV and vermin proof, and further serves to stop the travelof fire and smoke from one floor to another'.
Where plumbing and heating pipes are run through the floors, suitable holes may be eut in the floor members j, and if the holes are sufficiently large to weaken the said members, the latter can be Vstrengthened around the holes in any suitable manner. The sheet metal Hoor construction is especially adapted for use in buildings having Vwooden floors, but it is also capable of-being used in buildings having concrete iioors, in which case, the nailer strips 37 are omitted, and the hollow beams' areV filled with concrete or the like, and the floor members f serve as forms to support the concrete, thereby avoidingithe use of temporary forms. lV hen used in a building havinga concrete floor, the licor members f'may be slit or expanded to better engage the concrete. In practice, the sheet metal beams are made of sufficient depth to sustain a given load on substantially long span, and are separated byV substantial spaces. For ordinary spans, which range from 8 to 20 feet, a beam of a depth of from t to 16 inches is preferred and a separationV of from l0 to 16V inches on centers. Y
Claims zl l. In a building construction, in combination, a sheet metal floor plate comprising a plurality of beams and intermediate plate members of greater width than said beams, the latter having Vconverging side wall members forming the lower part of the beam and shorter diverging members forming .the upper part of the beam and separated at their widest part a distance which is less than the width of the lower part of the beam at its greatest width, said intermediate plate members being wider than the `depth'and widt-h of the beam. i
2. In a building construction, in combination, a sheet metal floor comprising a plurality of sheet metal beams having adjacent side walls separated'fromeach other and integral with intermediate pla-te me-nr dth than said beams,
lnailer strips interposed between and sup*- ported by the side walls of said beams, and
a iooring secured to said nailer strips.
3. In a building construction, in c0mbination, a sheet metal floor plate comprising aaafaaae a plurality of beams integral with inten name to this speceaton in `he presence mediate plate members of greater Width of two subscribing Witnesses.
than Jche depth of said beams 'the latter i. having converging side Wall members and CLARENCE T' MCFARLAND' shorter dvergng members, and a naler Vtnesses: strip supported by the dvergng members. JAS. H. CHURCHILL,
