To all @720m it may concern.
Be 1t known that li, WILLIAM H. EvERs, a cltizen of the United States, residing at Cleveland, in the county of Cuyahoga and' State or Ohio, have invented a new and use'- ful llmprovement in Concrete Flooring Constructions, of which the following is a specification.
This invention relates generally to reinforced concrete constructions and more particularly to a reinforced concrete Hoor construction.
'llhe object of my invention is to provide a reinforced concrete floor and ceiling construction of uniform dead load irrespective of span, and also a reinforced floor and ceiling construction of uniform height irrespective of live load and alsoa construction of uniform dead load and height irrespective of span and live load.
rfhe invention also has for itsobject the construction of a floor of very light weight and at the same time provide unusually large air spaces which can be utilized for the arrangements of pipes or conduits and which will also aid in making the construction sound proof.
Heretofore oors have been constructed with hollow tile or a combination of iron beams and hollow tile or of solid slabs of reinforced concrete.
lln all of these constructions the depth varies with the spans and with the load they are called upon to carry. Crdinarily they are not sound proof without the addition of some deadening material which adds materially to the weight and cost of the floor construction.
My invention comprehends the employment of. a 'series of reinforced concrete beams in combination with slabs of plastic material, said reinforced concrete beams and slabs being of constant depths and constant Weights, the only varying element being the reinforcement which varies with the span and with the live load.
My invention consists also in certain details of construction and novelties of com specication Figure l is a cross sectional view of a portion of a concrete floor andcelllng construction bodying my nvntlon the reinforced concrete beams cross section.
Fig. 2 is a similar view in which reinforced concrete fbeams are employed.
lFig. 3 is a detail perspective view of the positioning wire employed in the "lV-beam. Fig. L is a detail perspective view of the positioning wire employed in the f-beam.
lliig. 5 is a perspective view illustrating the details of construction and the arrangement of the various parts constituting my being 'Il' shape in invention.
Referring to the drawings A indicates the reinforced l'l"-beams and B the reinforced concrete lli-beams and C indicates the slab of cement or other plastic material arranged upon these beams and D represents the ceiling below, which is attached to the bases of the beams in any approved manner. The reinforced concrete beams are manufactured and then transported to the point of erection and are arranged or supported in a building exactly the same as a metallic beam or girder would be arranged and supported, the distances between centers being governed by the character of the structure desired.
ln orderthat these beams can be manufactured at one point and readily transported and erected they must be of minimum weight and of constant end sections and in order to accomplishthis the metallic reinforcements must be arranged and held at the proper points in order to utilize thel maximum compression, tension and shear strength of the steel reinforcement.
rllhe positioning of the longitudinal reinforcements is secured by means of positioning wires lE and lF which ll have illustrated in Figs. 3 and 4 respectively and which are' also shown in vconnection with the 'll' and llbeams. Vln the 'Il' beam construction one central tension wire or rod Cr and two side wires or rods Cr are employed and one compression wire or rod H, these wires or rods being absolutely positioned by means ofthe positioning wire lE which is coiled upon itself to provide the central 'positioning eye lil and the side positioning eyes E2 and t e upper positioning eye E3, the members of the wire crossing as shown at E4 and the free ends E5 proJecting upwardly from the top of the beam and are intended to be bent down in opposite directions as shown in full lines in lFig. 3 and for a purpose hereinafter explained, 'llie Gross portions of the e' lll@ 4plastic ceiling D.
serve as the necessary shear rods within the web of the beam. 1n the vI-beam construction there is employed the central tension wire G and side tension wires or rods G and in addition to the central compression wire H there are employed two side compression wires or rods H, these wires or rods being absolutely positioned byV means of the positioning wires F, shown in detail in Fig. 4, each wire being bent to provide the central positioning eye F and side positioning eyes F 2 for the tension wires or rods and the central eye F3 and side eyes F4 for positioning the compression wires or rods H and H and the ends of the wire F are carried out through the top of the beam and extend a considerable distance, being adapted to be bent down in opposite directions, so as to overlap as shown in Figs. land 2, therebyl providing the end shear rods or reinforcing members in the floor slab C, these overlying slabs C forming the 'flooring proper by enveloping and combiningo these positioning and shear wires becomlng an essential and unit part of the compression section of the floor construction. The ceiling D as previously stated is attached to the bottom of the beams in any suitable manner.
The tie or positioning wires E and F are manufactured with their ends left of proper length to serve as shear and compression rods in the upper slab. These tie or posi-E tioning rods exactly space and pro er1 position the longitudinal wires or ro s and G', and H and H. v
The assembled steel frame work is then positioned in rigid molds .in the shop ready l to receive the concrete or other cementitious material which is of a consistency to readily pour in the mold and around the assembled steel. After 'proper setting of the concrete the mold is removed and the beams are ready for transportation and erection on the building site, and may be set to twenty-four inch centers ready to receive lthe slab C and Temporary forms -between the beam, blocked against the lower iianges, or a metal lathing for the beams may beused upon which the projecting ends of the tie rods are now bent down into. proper position, these downwardly bent ends overlapping as most clearly shown in Figs. 1 and 2. The slab of minimum section is then poured of concrete or other cementitious material, adhesion to the tops of the beams being secured either by scariying the upper flange or by providing a groove as indicated in Figs. 2 and 5. The slab com-l pletelyA envelops the projecting tie rod ends acting as shear rods and uniting the various parts into a" combined whole. After the slab has set,.'the forms are removed and the ceiling applied according to any method.
From an examination of Figs. l and 2 and 5 it is evident that nearly sixty per cent. of
-pression the cross sectional area is air space 'which can be utilized for conduits installation and ventilation and these large air spaces also provide a sound proof and moisture proof floor.
It will be therefore seen that I provide a novel floor construction which is strong and durable and at the same time economical in the employment of materials,.and at the same time providing a floor of maximum strength and minimum weight.
