REINFORCED-CONCRETE BEAM.
Specification of Letters Patent.
Application filed December 30, 1908.
Patented Mar. 29, 1910.
Serial No. 470,018.
To all whom t may concern:
Be it known that I, GUILLAUME DUJARDIN, a subject of the King of Belgium, and resident of Huy, Belgium, have invented certain new and useful Improvements in Reinforced- Concrete Beams, of which the following is a specification.
This invention relates to an improved form of concrete construction and has to do more particularly with concrete beam constructions.
The invention has to do with that kind of concrete beams which are provided with transversely disposed openings divided by suitable partitioning members and a further object of the invention is to provide a new arrangement of reinforcing whereby the beam will be materially strengthened and rendered more eilicient in use. i
The invention will be more fully described in connection with the accompanying drawings and will be more particularly pointed out in and by the appended claims.
In the drawings, Figure l is a longitudinal sectional view on line 11 of Fig. Q. Fig. 2 is a sectional view on line 2-2 of Fig. l. Fig 3 is a sectional view on line 3-3 of Fig. l.
Like characters of reference designate similar parts throughout the different figures of the drawings.
As shown beams are provided as indicated at a and each beam is provided with a plurality of openings b transversely disposed with respect to the length thereof. The openings o are preferably elongated and extend completely through the beams from side to side and are divided by partitions a. The division of openings o, in the manner described, forms strong upper and lower walls a2 and a3 which join the partition walls a and by rounding the ends of the openings b a very eflicient arched juncture of the partitions with the Lipper and lower walls is provided.
According to my invention the beams are rectan lar in cross section and are adapted to lie 1n parallel relation with each other to form a floor or roof structure. In order to provide a close juncture between the sides of the beams one side of each beam is provided with a longitudinal recess f and the other side with a complementally formed projection g. As shown in Fig. 3 the projection g of one beam is adapted to fit 1n the recess f of the next adjacent beam forming a rabbeted joint and if desired the beams may be so disposed as to cause the openings Z) to register.
Reinforcing rods c are longitudinallvI embedded in each beam and are preferably disposed at each corner thereof, there .being four rods for each beam. Between the partitions o the rods c are connected by transversely disposed horizontal reinforcing wires c which are embedded in the upper and lower walls a and a3 and extend across the beams above and below the openings b. Vertically disposed reinforcing wires d are embedded in the partitions a and are connected with the rods c at each side of the beam. In addition to the foregoing, horizontallyI disposed reinforcing wires cl are connected with the rods c and preferably the wires el are disposed in the same plane as the wires d. The reinforcing wires al, d and e may be simply wound about the rods c and their projecting ends may be utilized for reinforcing the members of the rabloeted joint as clearly shown in Fig. 3 wherein it will be seen that the ends of the wires project outwardly beyond the rods c. It will be seen that the beam constructed 1n accordance with my invention is formed to afford a maximum sustaining efficiency irrespective of the reinforcement and that the improved reinforcement provided serves to strengthen and brace the means so that it will be able to stand whatever stress to which it may be ordinarily subjected.
I claim 1. The hereindescribed reinforced concrete beam construction comprisin in combination, a plurality of beams eac 1 composed of concrete and each provided with a plurality of transversely disposed openings spaced apart from each other with vertically disposed transverse partitions between said openings, longitudinally disposed reinforcing members embedded in each beam adjacent the lateral corners thereof, vertically and horizontally disposed reinforcing wires embedded in each beam centrally of each partition and connecting said longitudinal members, transversely disposed horizontal reinforcing wires embedded in each beam above and below said openings and between said partitions and connected with said longitudinal members, each of said beams being longitudinally recessednon one ofnits sides and provided on its opposite?sidwithacomplementally formed lateral projection.
UNTE STATENT @am 2. The hereindescribed reinforced concrete beam construction comprising in combination, a plurality of beams each composed of concrete and each provided with a plurality of transversely disposed openings spaced apart fiom each other with vertically, disposed transverse partitions between said openings, longitudinally disposed reinforcing members embedded in each beam adjacent each lateral corner thereof, vertically and horizontally disposed reinforcing` wires embedded in each beam centrally of said partitions and connected with said longitudinal members, and transversely disposed horizontal reinforcing wires embedded in each beam above and below said openings and between said partition and connected with said longitudinal members.
3. A reinforced concrete beam provided with a plurality of transversely disposed openings spaced apart from each other and vertically disposed transverse part-itions between said openings, longitudinally disposed reinforcing members embedded in said beams, vertically and horizontally disposed reinforcing wires in said beams and convvv, van.;
nected with said longitudinal members, and transversely disposed reinforcing wires embedded in said beams and connected with said longitudinal members between said verticallyy and horizontally disposed wires.
4. A concrete beam provided with a pluralit-y of transversely disposed openings spaced apart from each other with vertically disposed transverse partitions between said openings, longitudinally disposed reinforcing members embedded in said beam, vertically and horizontally disposed reinforcing wires embedded in said partition and coniiected with said longitudinally disposed members, and transversely disposed reinforcing wires embedded vin said beam above and below said openings and between said partition and connected with said longitudinal members.
ln testimony whereof have hereunto set my hand in presence of two witnesses.
GUILLAUME DUJARDIN.
