Description
H. F. YOUNG CONCRETE BEAM Jux re 17, 1930.
Filed May 21, 1928 INVENTOR flan are /T You/7g BY 647M 1 (2M1 A TTORNEYX Patented June 17, 1930 PATENT OFFICE HOWARD F. YOUNG, OF KALAMA ZOO, MICHIGAN CONCRETE BEAM Application filed May 21, 1928. Serial No. 279,353.
This invention relates to improvements in concrete beams or joists and their means of support and to the method and apparatus for manufacturing the said beams.
' The objects of the invention are, 1
First, to economize in the material of both the concrete and the reinforcing members.
Second, to provide improved concrete reinforcement for I-beam or joist structure.
Third, to provide an improved construction of beam lending itself effectively to cross supports.
Fourth, to provide an improved construction witha knock-out part to form cross passages through the web ofthe beam.
Objects relating to details and economies of construction will appear from the detailed description to follow. The invention is defined and pointed out in the claims. A beam and its method of manufacture is illustrated in the accompanying drawing, in which Fig. 1 is a detail perspective view of a concrete beam embodying the features of my invention, with the cross support bracket in po- 5 sition, the relation of the reinforcing members being indicated by dotted lines.
Fig. 2 is a plan view showing the conne ction of a pair of cross beams or joists to a main beam or joist.
Fig. 3 is a transverse detail sectional view taken on line 33 of Fig. 1, showing the form of reinforcing cross strands and indicating their method of support irrthe. form.
Fig. 4 is a detail perspective view of a section of trough 01- form in which my improved joist of I-beam is formed.
Fig. 5 is a detail cross sectional view of the forming roller and the forming trough in their operative positions.
41) Fig. 6 is a detail perspective view of a double head cross support bracket coupling for one of my improved I-beams.
Fig. 7 is a detail of the knock-out section at the center of the web of the beam.
The parts of the drawings will be identified by numerals of reference which are the same in all the views.
1 is a concrete I-heam having the usual web 2 and double heads 3, 4. Longitudinally of the angles of the beam are disposed rein forcing rods 5, and centrally .of each head is a larger reinforcing rod 6. These rods 5, 5 and 6, 6 are connected together by cross wires 7 at intervals, as seen in Fig. 3, the ends of the same being folded upon themselves hairpin- 5 Wise toform legs for supporting the completely organized reinforcing member in the trough mold. The main rods are held together by a series of diagonals 8 forming diagonal squares 9. The diagonal members are 0 increased in size and number according to the strains to be imposed upon the beams.
Centrally of each diagonal square I weaken a circular section and preferably insert a metal ring 10 which circumscribes a round disk 11 that can be readily broken out.
Connectors 12 of hairpin type may be inserted over the lower main st and (S or otherw'ire secured in the concrete.
From the description of the I-beam it will be seen that the reinforcing members can be organized in sections and can be placed in forming troughs 13 having side walls lland a divided end walls 15, slotted at 16 to accommodate the main strands of the concrete re- IIIEOICIDO'. A strip of ren fm'cmg as organized can be placed in the trough. which is suitably conformed, and the legs formed of the wires 7 at each side will support it in proper.
spaced relation. The floor of the trough is provided at intervals with projections 17 which form corresponding depressions in the center of each of the diagonals of the reinforcing, which can be readily knocked out. It is preferable. however, to )lace a metal ring 10 around each boss or pro ection so that it may be incorporated in the concrete and then when the disk 11 is knocked outa clean edge will be presented. This is for the purpose of makin a cross aperture in the beamand also an efiective simple support for cross beams.
A' forming roller 18 is provided having suitable contour to-roll semi-plastic"concrete into the trough-like form. The roller is pro-' "idcd With bosses 171 corresponding to the bosses 17. It is proi'ided'with geared pinion 19 at each end engaging suitable racks-201011 each side of the trough to cause a register of the bosses 17 and 171. The roller is provided with pro'ecting pins 21 which may serve as handles or manipulating the same by hand or a suitable connection for power operation. The cross beam connection is a bracket 22 with a suitable seat 23 for the end of the cross beam The bracket is secured in place by a disk-shaped boss 24 with an upwardly projecting lug 25 for insertion through the aperture in the beam. Where it is necessary or desirable that the cross beams meet between the apertures, a double bracket is provided (see Fig. 6) with angle bar connection to afi'ord support for the cross beam at any intermediate point; Having thus described my invention, what I claim as new and desire to secure by Letters Patent is: 1. A concrete I-beam or joist comprising upper and lower heads and connecting we portion, longitudinal central strands in each head and longitudinal lateral strands each side of the main strand, diagonal cross strands connecting the said main strands and disposed within the web of the beam 5 and forming diagonal squares, knockout sections at center of each square with surrounding metal ring, and cross reinforcing members connectin the longitudinal reinforcing members, olded upon themselves and forming leg supports, as specified. 2. A concrete I-beam or joist comprising upper and lower heads and connecting web portion, longitudinal central strands in each ead and longitudinal lateral strands each side of the main strand, diagonal cross strands connecting the said main strands and disposed within the web of the beam and forming diagonal squares, knock-out vsections at the center of each square, and cross reinforcing members connectin the longitudinal reinforcing members, olded upon tgefinselves and forming leg supports, as spec- 1 e 3. A concrete I-beam or joist comprisin upper and lower heads and connecting we portion, longitudinal central strands in each head and longitudinal lateral strands each side of the main strand, diagonal cross strands connecting the said main strands and disposed within the web of the beam and forming diagonal squares, and cross reinforcing members connecting the longitudinal reinforcing members, folded upon themselves and forming leg sup orts, as specified. In witness whereo I have hereunto set my hand.
