FLOOR CONSTRUCTION.
Specification of Letters Patent.
Patented Oct. 5, 1920.
Application filed May 15, 1919. Serial No. 297,211.
To allwhom it may concern;
Be it known that I, WiLLIAM'S. HU'roHIN- SON, a citizen of the United States, and a resident of Bethlehem, in the county of, Northampton and State of Pennsylvania, have made a new and useful Invention in Floor Constructiom of which the following is a specification.
y invention relates to building construction and particularly to that type of building wherein steel floor beams of girder construction are spaced in parallel rows and subfloors of reinforced concrete are applied thereto. To avoid the costly process of erecting numerous forms for pouring the concrete in its final position, it is the growing practice to form the subfloor of slabs of reinforced concrete manufactured in suitable widths and lengths at a convenient point and shipped to the locations of the buildings being erected.
The usual method of applying these precast slabs is to support them upon the top of the floor beams with adjacent slabs practically abutting each other. To secure strength, the slabs are of modified arch construction, being from four to six inches in depth.' This depth of slab when used in above construction results in the addition of such dimension to the distance between each ceiling and the floor above which, in a multistoried building, becomes a considerable factor in the amount of-steel, brick, plumbing, labor and other costs necessary to erect the building.
The object of my invention is to decrease this additional thickness at each floor. In my patent application. Serial Number 297210, I disclose certain methods of applying the subfloor below the tops of the floor beams by resting the slabs on the lower flanges of the beams. My present invention discloses another method of accomplish is illustrated in the accompanying drawings forming part of this specification and in which Figure 1 is a plan of a portion of a subfloor of my improved construction, Fig. 2 is a vertical transverse section through a floor slab and its supporting beams when the beam is fireproofed beneath the floor slabs and Fig. 3 is a section through one floor beam only where such fireproofing is omitted.
The floor beams 1 may be of I beams as shown or any other type, either integral or cessive sides 6-6 built up, having upper and lower flanges 2 and 3 respectively. At intervals along the beam, I apply an inverted U shaped hanger or yoke 4 having a horizontal portion 5 and depending sides 6. Portion 5 rests upon the topfflange 2 of the floor beam and may be secured thereto. When fireproofing is applied to the bottom flange 3 of beam 1, sides 6 of the yoke extend downwardly and support the fireproof slabs 7 by means of bolts 8 which are flattened at one end to be secured to side 6 of yoke 4 and are provided with a nut 9 to hold the slab 7 Any other suitable slab retaining means may be substituted for bolt 8 and nut 9.
Below the top of beam 1 and running parallel therewith are continuous, floor slab support angles 10. The vertical flange of each angle is secured to the outside of sucof hangers 11 and its horizontal flange is faced away from the beam. The horizontal flanges of opposed angles 10-10 respectively support the opposite edges of each floor slab 11.
Clips .12 act as bracing members to prevent opposed supporting angles 10 from spreading away from each other and may be applied to the inside of hangers 4- as shown or dir ctly to the back of angles 10 at other intervals. If hangers 4 are sufliciently heavy to resist any bending force likely to be imposed on them or are adequately braced by bottom flanges 3 and slabs 7, bracing clips 12 may be omitted.
My construction makes it possible to utilire the pro-cast floor slabs with all their desirable features without increasing the height of each story and without removing any portion of the floor beam to insert it in place. It is very easy to lower the slabs into place as there is no framing extending above the slab outline to be removed or dodged in placing the slabs between the top and bottom flanges of the floor beams.
I claim 1. In a floor structure, a floor beam, yokes spaced along the beam and mounted thereon, a floor support member extending parallel to said beam and secured to said yokes; a yoke reinforcing member, secured to each yoke near the point of support of said support member and located between the yoke and the beam and engaging the web of the beam, and floor units having edges mounted on said floor support member.
2. In a floor structure, parallel floor beams, yokes spaced along the beams and straddling the top flange thereof, a separate floor supporting -membersecured to the yokes associated with each beam and extending longitudinally of the beam, and a sepa-- rately formed floor unit located between said beams and: having its edges supported by said floor supporting members.
3. In combination in a floor structure,
parallelfloor beams, yokes spaced along each floor beam and straddling the top cord,
thereof, a separate continuous floor support member extending longitudinally of each beam and rigidly secured to the yokes associated with the beam, and separately formed floor slabs located between said beams and supported at their edges only by 7 said floor support members.
4. In a floor structure, a floor beam, yokes spaced' along the beam and mounted thereon,
and floor units having their edges mounted:
on said floor support member.
In testimony v whereof I have hereunto subscribed my hand 1919. i
