1,573,280 F. E. SIMPSON REENF'ORCED FLOQRING CONSTRUCTION Filed May 31, 1 923 I II ATTORNEY FRED EARNEST SIMPSON, 015
ronon'ro, onrnnro, CANADA.
Application filed May 31,
To all whom it may concern:
Be it known that I, FRED Ennnnsr SIMP- soN,a subject of the King of Great Britain, andresiding at No. 142 Peter St, in the city of Toronto, in the county of York and Province of Ontario, Dominion of Canada, have invented a new and useful Reenforcedlilooring Construction, of which the following isthe specification.
This invention relates to reenforcod flooring construction, as described in the present specification and shown in the accompanying drawings that form part of the same.
The invention consists of the novel features pointed out broadly and specifically in the claims for novelty following a description containing an explanation in detail of an acceptable form ofthe invention.
The objects of the invention are; to provide a reenforced flooring construction 'including spaced reenforced concrete joists re tained in position by hollow spacing sections; and provided with a slab of concrete, formed of cement and aggregates of suitable proportions, to be laid in plastic form, and in which may be embedded sleepers, to which a flooring of wood or equivalent material may be fastened; to-provide a reenforced flooring construction from a hygienic point ofview, being no proof, vermin proof,
sound proof, warm, and well tempered, and
desirable of depth of construction, wherein the omission of I girders effects saving of steel work and consequent dnninut-ion of risk in case of fire; to provide a reenforced flooring construction which is easily comprehensible, having clear static calculations, which admit of the most QXlZEIlSlVG use of concrete, and which provides an absolutely even soflit without interruption up to spans of thirty feet, whereby the architectural and decorative formation of the ceiling is unimpeded; to provide a reenforced flooring construction admitting of little moisture and dampness, the sections being brough upon the site of assembly, and only the top layer b'einglaid in plastic form to provide a reenforced flooring construction wherein hollow spacing sections are employed which may accommodate ventilating tubes, water pipes, gas pipes, or electric wiring to provide a reenforced construction which obviates the necessity of wnterin which greatly expedites the assembling of the sections to provide a reenforced flooring construction which may be used within a very 1923. Serial No. 642,520.
short period after the assembling thereof and in which holes may be easily cut; in which the section may be easily trimmed, and in which damaged parts may be re placed with facility, or to which a continuous construction may be easily joined.
In the drawings Fig. l is a fragmentary perspective view of a section of recnforced flooring construction.
Fig; 2 is a fragmentary perspective view illust'ating a section of a concrete web as embodied in the invention.
Fig. 3 is a fragmentary view of one of the spacing sections, and
Fig. l is perspective view of one of the corrugated sheet metal concrete retaining sections.
Like numerals of reference indicate corresponding parts in the various figures.
The numerals l designate in their entirety, concrete joists, in the lower part of which a plurality of binding rods 2 are embedded. It will be observed that the joists are very narrow in proportion to their height, so that they will present a very high supporting strength. Abutnients 3 and 4 are provided with inclined surfaces 5 and 6 and shoulders 7 and 8, upon which the flanges 9 and 10 of the spacing sections 11 bear. The sides 12 and 13 of said spacing sections are also inclined, which serve to bring about a wedging effect upon the webs when positioned between them. Semi-cylindrical openings designated as at 14% extends longitudinally through said spacing sections 11 and serve to accommodate for ventilating tubes. water pipes, gas pipes, or electric wiring. The formation of the spacing sections 11 is such as will afford great rigidity combined with the maximum lightness. The numerals 17 designate concrete retainers formed of scrap sheet metal of any convenient length. The corrugated arcuate surfaces 18 provide very rigid supporting arches for the plastic concrete of which the slab 19 is formed. 20 and 21 designate side walls having their extremities 22 bending inwardly which bear upon the spacing sections 11.
Ensuing the assembling of the joists 1, the spacing sections 11, and concrete retainers 1", the slab 19 is laid in its plastic state. Thus the fresh concrete obtains a firm grip on the old concrete of the webs (have been made previously and have properly set), not only on the tops of the webs, but also along the sides of them to the junction of the retainers 19, s0 that the adhering surface is sufficient to, form a Very rigid construction. It is obvious that the adhesion between the old and the new concrete will be such that,practically speaking, the slab and the webswill form a monolith.
Sleepers 23 are embedded in the slab 19 when in its plastic condition, and serve as retaining means to which the wooden flooring 24 may be fastened.
' From the foregoing elucidation it is thought to be obvious that a: reeniforced flooring construction made in accordance with this disclosure is particularly well adapted for commercial purposes by reason of the facility with which the component sections may be made, and assembled on the site of construction. It is also apparent that deviations from such detail may be resorted to in the precise formation on and association of the sections without forming'a de- ,parture spirit of the invention and the scope of the appended claim.
What I claim is:
A reenforced flooring comprising parallel concrete joists having tapering base portions and reduced upper portions forming shoulders at the upper ends of said bases, tubular concrete elements having fiat upper sides projecting over said shoulders and tapering'walls fitting between said joist bases and'flat floors with grooves in the under sides, metal arches supported on the flat upper sides of said tubular elements, a concrete bed submerging the upper ends of said joists and supported on said metal arches.
In testimony whereof I afiix mysignature this 9th'day of May 1923, at the city of Toronto, in the Province of Ontario and Dominion of Canada. Y
