- REINFORCED CONCRETE STRUCTURE.

Specification of Letters Patent.

Patented Sept. 14, 1909.

Application filed November 25, 1908. Serial No. 464,385.

To all whom it may concern:

Be it known that I, ERNEST MoCULLoUGH, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Reinforced Concrete Structures, of which the following is a specifloation.

This invention relates to improvements in reinforcing concrete structures and more particularly to web reinforcement for beams, slabs or the like and the primary object of the invention is to provide an improved strengthening web of this character constructed of reticulated material.

A further object is to provide an im proved web reinforcement for concrete structures formed of a plurality of superposed sheets or strips of reticulated material secured together in such a manner that the extremities of the sheets or strips may be bent or deflected at an angle to the body portions so as to extend transversely across the body of the beam or slab to resist internal stresses.

A further object is to provide an improved reinforcing web which may be constructed as a unit and collapsed for shipment purposes, and improved means for guiding the user in bending or shaping the web for use.

A further object is to provide improved means for supporting and properly positioning the web above the bottom of the mold or form in which the beam or slab is cast.

A further object is to provide improved means whereby tension rods may be secured to the web when desired for reinforcing the same.

A further object is to provide an improved device of this character which will be simple, durable, cheap and light in construotion, and effective and eflicient in operation.

To the attainment of these ends and the accomplishment of other new and useful objects, as will appear, the invention consists in the features of novelty in the construction, combination and arrangement of the several parts hereinafter more fully described and claimed and shown in the accompanying drawings illustrating the embodiment of the invention, and in which Figure 1 is a perspective View of an improved structure of this character constructed in accordance with the principles of this invention and showing the beam or slab in diagram. Fig. 2 is a detail view of one unit in a collapsed form for shipment. Fig. 3 is an enlarged detail sectional view on line 33 of Fig. 2. Fig. 4.- is a detail perspective View of the preferred form of reticulated material, from which the reinforcing web is constructed showing a portion of the body of one of the strips, the angularly deflected end thereof and the horizontally deflected extremity of the end. Fig. 5 is a diagrammatic View showing one manner of using this improved reinforcing web. Fig. 6 shows a modified form of the invention.

Referring more particularly to the drawings and in the present exemplification of the invention, the reinforcing web is constructed of a plurality of superposed strips or sheets of reticulated

material

10, 11, 12, which maybe of any desired width but of varying lengths, so that the extremities of each sheet or strip will terminate short of the extremities of the next adjacent strips or sheets when the web is collapsed. The

respective ends

13, 14, 15 of these sheets of fabric may be bent or deflected at any predetermined points and at angles to the body portions of the respective sheets. These bent or deflected ends are preferably disposed in planes inclined to the vertical and the respective extremities 16, 17., 18, of the

inclined ends

13, 14, 15 are deflected horizontally and in a direction preferably away from the longitudinal center of the respective sheets. The extremities 13, 1 1, 15 of the sheets are of such a length as to extend across the body of the beam to assist in tying together the top and bottom of the beam, and to resist internal stresses of the beam, and are of such lengths that the horizontally deflected extremities 16,17, 18, may stand at any predetermined distance from one surface of the beam or slab according to the thickness of bonding necessary. Any number of these strips or sheets of reticulated

material

10, 11 and 12 may be employed and in the present exemplification of the invention three of such sheets are shown and these strips or sheets may be connected or secured together to form a reinforcing unit in any desired or suitable manner, preferably by means of cooperating strips of

material

19, 20, 21, one of which strips is arranged adjacent the bend formed by the

respective ends

13, 14, 15 of the sheets and the cooperating strip being arranged below the respective stripsand adjacent the face of the outermost strip 10. Thesestrips may be secured together in any desired or suitable manner so as to form independent clamps, preferably by means of a fastening device 22 in the form of a threaded bolt or: screw which is provided with a tapered or pointed extremity 23. Any number of these fastening devices 22' may be employed for v each of the pairs of strips and are adapted to pass through the cooperating strips and the adjacent portions of the superposed sheets of

fabric

10, 11, 12.

Suitable nuts

24, 25, may be provided which surround the Y bolts 22, one adjacent each of the respective strips and are adapted to be adjusted on the bolt so as to cause the strips 21 to clamp the superposed sheets of reticulated fabric. The bolts are of such a length as to extend for "some distance beyond each of the clamping or fastening strips and may be adjusted with respect to the superposed sheets of fab- 25

ric

10, 11, 12, by

looseningthe nuts

24, 25

so that the reduced or pointed extremity 23' of the bolts may be projected any desired distance beyond the lowermost sheet of the fabric 10. By adjusting the bolts 22 below,

the lowermost clamping member, it is pos sible to project all of the pointedor conical "form, thereby permitting the plastic mates rial which forms the bottom or slab toentirely surround the reinforcing web as the material is poured into the mold;

With this improved construction it will be apparent that the clamping members 19,

1 20 'a'nd2l may be located at predetermined points so that when the unit isassembled, it may be shipped in a collapsed or folded condition to the user. lVhen itis desired to use the structure allthat is necessary is for the user to bend or deflect thee-xtremi-ties of the respective sheets of reticulated'material to the position shown in Fig. 1, the

clamping strips

19, 20 and 21 being securely held in position and being located at the points ad jacent which the bends ofthe material are to be made, thereby insuring the proper bending or shaping of the reinforced Web in the hand of an inexperienced person.

If desired, and in order to reinforce the beam or slab tension members, preferably'in I the form of metal bars or rods, may be employed, and these tension members 27 may be interposed between the layers of fabric so that the extremities thereof will project through the deflected portions l3of the ma; I i ermost layer. Any number of thesetension; r.

members 27 may be employed according to' the'width of the naterial from which the beam or slab is constructed and may also :be of any desired length but are preferably of I such a length that when the extremities-"of?" the beam 28,; shown in dotted lines in'Figql,

rest upon thesupports29, the extremities'of f i the tensioirmembers will'project over the supports; When thereinforeingweb is col-" lapsed or folded for shipment, the deflected 7 portions 13 of the-outermost memberwill be bent to rest upon the extremities of the ten-- sion members 27, as shown more clearly; in Fig. 2 of the drawings. 7

Obviously, instead of sion members 271 between thegsheets of the interposing the ten- 2 reticulated material, they may be disposed against the outer face of the outermost sheet, in whiche'vent they may be secured in position in a similar manner with theeXcepQ tion that the-respective adjacent clamping strips will directly engage the tension members. j V A plurality of the reinforcingwebunit-s thus formed maybe employed for-constructi- 7 ing 'abeam of a length somewhat greater than the length of the unit to form a single span girder and in this event-the unitsmay be arranged opposed to each other so that the bottom or base of one unit'qwillystand'.

' adjacent one face of the gi'rder or beam and the bottom orbase of another unit may. stand adjacent the opposite face of'theg'irder orbeam, so that the vangularlyr-deflected;

extremities

13, 14k, 15 will be disposed between the adjacent angnlarlydeflected portions of the next adjacent unit and thesendeflected Q .10.:

portions are spaced from each other asufiicient distance'to cause a space to intervene between-two of the adjacent 'deflected portions to permit theplastic material 'to fill the spaces therebetween. r s

When the beam or girder is constructed in themanner shown in Fig. 5 and thetension rods or members 27 are employed, the flatter supports or uprights 29. One ofthe unitsli's also arranged to stand astride of-eachf of the uprights or supports soas-tofresist1'alLre are of such a lengthias to project QVBlfthe j versed stresses of the beam or. girder. Inl this form of the invention and "whena plu -QQ I rality' of units are employed, thej miay be 1 supported in the mold or-form in any dethe fastening bolts 22'will engage the bottom of the mold for spacing the unitfrom; f the bottom to permit the plastic :m'at'eri-alto completely surround the unitsj a'nd when thus completed, portions fo'f the units willbe disposed adjacent to and will extend parallel with thetop "and bottom o-f the-beamor girder to furnish a bond.

If desired, the reinforcing "web" mir h? constructed as a continuous unit, that is, so that the web will extend from one end of the girder or beam to the other, as shown more clearly in the modification shown in Fig. 6 of the drawings. When the reinforcing web is thus constructed, the sheets of reticulated material may be continuous and may be fastened together at intervals by the cooperating clamping

members

19, 20 and 21 in the same manner as the single unit, the co-- operating clamping members being spaced longitudinally from each other to permit the superposed sheets of reticulated material to be angularly deflected, as at 30, 31, 32, at predetermined intervals to connect portions of the web which are disposed parallel to each other and spaced from each other any desired distance according to the depth of the girder, beam or slab. These parallel portions are also spaced longitudinally from each other whereby the angularly disposed

portions

30, 31, 32 will connect the said parallel portions. In this exemplification of the invention, as well as in the form shown in Fig. 5, the tension rods 33 may be arranged adjacent the portions of the reinforcing web which extend adjacent the lower face of the girder, beam or slab, the extremities of which extend over the supports or standards 29 and similar tension rods 34 may be employed which are secured to the portions of the web which stand adjacent the opposite face of the beam or girder and these tension rods 34 may be of a length to terminate short of the next adjacent tension rods but are arranged to extend across the uprights or standards 29 so that their respective extremities will terminate at point-s between the uprights or standards. In this form of the invention the reinforcing web will be constructed as a unit and will be shipped in shape ready for use but in the other forms of the invention the reinforcing web may be shipped in a collapsed or folded form. Obviously the tension rods 33, 34:, may be omitted when desired.

Although in the present exemplification of the invention the web is shown as being constructed of sheets of sheared or expanded material, it is to be understood that any suitable reticulated material, such as sheared, woven or welded fabric may be employed and the sheets secured together so that the body portions thereof will be disposed in different horizontal planes.
