United States Patent US. Cl. 52-236 4 Claims ABSTRACT OF THE DISCLOSURE A construction system utilizing a plurality of combination column and beam units or trees assemblable so as to define a concrete building frame for the reception of a plurality of pre-formed concrete slabs. Each tree consists of upper and lower column sections which join at mid-height to similar column sections on subjacent and supeljacent trees, the joining being effected through embedded splice sleeves. Each upper column section is spaced above the transverse tree beam to which it is joined for the accommodation of a slab joining pour whereby a positive interlock between the beam-supported slabs and the frame unit or tree is achieved.

The instant invention is generally concerned with a concrete construction system, and more particularly relates to a system wherein the building frame, as -well as the floor slabs, are formed of precast units adapted to interengage and be locked together, utilizing grout and poured concrete, into a highly rigid concrete structure notwithstanding the preformed nature of the major components thereof.

A primary object of the instant invention is to provide unique precast combination column and beam units, referred to as trees, which are assembled so as to define a concrete building or tower frame.

Another significant object of the instant invention resides in the provision of a concrete construction system wherein preformed frame units are particularly adapted so as to not only combine with similar units in forming a concrete frame, but also so as to receive, support, and positively interlock with preformed horizontal concrete slabs for the formation of floors and ceilings.

A further significant object of the instant invention resides in the provision of frame units and slabs which are both internally reinforced and include embedded exposed reinforcing rods particularly oriented so as to receive and be bound by selectively poured concrete at the joining areas of the various components.

Another object of the instant invention resides in the provision of a construction system wherein the construction of a concrete frame building can be effected rapidly and continuously, without the delays normally encountered in concrete construction, in view of both the preformed nature of the components utilized and the specific configurations of the components wherein a stacking thereof can be continuously effected while the lower units are being intimately bonded together.

Basically, the objects of the instant invention are achieved through the provision of concrete building frame units consisting of, in the illustrated embodiment, an elongated beam defining, as an integral member, one complete span and two oppositely extending sectional spans, in conjunction with two upwardly projecting column sections and two downwardly'projecting column sections. The upper column sections are orientated, through reinforcing rods, in spaced relation above the beam for the accommodation of a concrete pour utilized in bonding the edges of a series of slabs supported on the beams. The slabs are bonded both to each other and to the beam, appropriate projecting reinforcing rods being utilized. The

column sections are in turn joined to adjacent column sections through the utilization of embedded splice sleeves.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIG. 1 is a perspective view illustrating a partially completed building being constructed in accordance with the system of the instant invention;

FIG. 2 is an enlarged perspective detail illustrating the various components of the system;

FIG. 3 is an enlarged cross-sectional view taken substantially on a plane passing along line 3-3;

FIG. 4 is an enlarged cross-sectional view taken substantially on a plane passing along line 4-4 of FIG. 2; and

FIG. 5 is a perspective view of one of the column and beam units or trees utilized in the system of the instant invention.

Referring now more specifically to the drawings, it will be noted that the concrete construction system of the instant invention basically includes two types of components, a preformed or precast column and beam unit 10, and a preformed or precast slab 12.

Each of the column and beam units 10, generally referred to as trees, consists of a horizontal beam 14, one or more upper column sections 16, and one or more lower column sections 18. The beam 14, in the illustrated embodiment wherein two upper and lower column sections are provided, includes a full central section 20 extending between the spaced aligned upper and lower column sections 16 and 18, and a pair of opposed beam sections 22, each projecting outwardly from one set of column sections 16 and 18. The beam 14, for the full length thereof through the contiuously formed center and two end sections 20 and 22, is provided with longitudinally extending reinforcing bars 24 which project longitudinally beyond the outer ends of the two end partial beam sections 22. The lower column sections 18 extend perpendicularly downward from the beam 14 and are integrally formed therewith. The upper column sections 16, which align with the lower column sections 18, are positioned in vertically spaced relation above the top of the beam 14 at a height approximately equal to the thickness of the slabs 12 to be used in conjunction therewith. These upper column sections 16 are maintained in vertically spaced relation tothe top of the beam 14, while being at the same time rigidly joined thereto and forming in effect a single unit therewith, by a series of vertically elongated reinforcing rods 26 which extend vertically through each pair of aligned column sections 16 and 18 and across the intervening space provided between the upper column section 16 and the beam 14. These reinforcing rods 26 terminate, at the upper ends thereof, within embedded splice sleeves 28 of the type illustrated in applicants copending applications Ser. Nos. 740,646 and 771,262, respectively filed on June 27, 1968 and Oct. 28, 1968. As an optional method, for ease in casting the vertical space between the upper column sections 16 and the top of beam 14 can be omitted and the cast extended to the beam 14.

The lower ends of the vertical column rods 26 project a substantial distance beyond the lower ends of the lower column sections 18 for the insertion thereof within upwardly opening splice sleeves 28 in the upper column section 16 of a subjacent unit or tree 10. Once inserted therein, as when forming a concrete frame of the type suggested in FIG. 1, an appropriate locking of the sleeve received rods is effected through the utilization of expanding grout within the sleeve, such a joint structure having been detailed in applicants above referred to applications.

The trees 10, as will be noted in the drawings, are specifically utilized to support the slabs 12 which are to be intimately bonded thereto by an appropraite concrete pour 30. Accordingly, each beam 14, along the full length thereof, is provided with a series of embedded and upwardly projecting reinforcing or tie rods 32, normally arranged in pairs and positioned inwardly from the opposed side edges of the beam 14. These rods 32, as suggested in FIG. 3, can constitute positioning abutments for the edges of adjacent slabs 12. The rods 32 will be bent at a height sufficient so as to be completely received within the slab joining pour 30.

Each of the slabs 12 is rectangular, preformed of poured concrete and reinforced by internal reinforcing and/or prestressing rods 34 crossing each other at right angles and projecting laterally beyond all four edges of the slab 12.

With particular reference to FIG. 1, it will be apt preciated that the column and beam units or trees are arranged in stacks spaced both longitudinally and laterally of each other, the number and arrangement of stacks depending upon the ultimate size and shape of the building being constructed. The corresponding units 10 in the longitudinally spaced stacks have the outer ends of the adjoining beam end portions 22 spaced from each other a distance sufiicient so as to normally define a bay of a width equal to that formed by the adjoining central beam portion 20. The projecting exposed ends of the beam reinforcing rods 24 are joined by grout filled splice sleeves of the type detailed in the previously referred to copending applications, with the exposed rod ends and associated splice sleeves subsequently being embedded within the joining pour 30. As an optional method, simple lap splicing of extended reinforcing bars 24 may be used.

The laterally spaced stacks of units 10 support and are interconnected by the precast slabs or slab units 12. Each of the slabs 12 is of a size, in one dimension, so as to fit closely between adjacent ones of the upwardly projecting column sections 16 lengthwise along the beams 14. The slabs 12, at right angles to the column received dimension thereof, are of a dimension so as to span the distance between the adjacent tree stacks and sufficiently overlap the laterally spaced beams 14 so as to firmly seat thereon, note for example FIGS. 2 and 3. The projecting ends of the slab rods 34 will, along the beam supported edges of the slabs 12, lie adjacent and bypass those of the adjoining beam supported slabs for a reception within the binding concrete pour 30, which also intimately bonds with the corresponding beams 14- through the upwardly projecting rods 32 thereon. Additional longitudinally extending reinforcing rods 35 can also be provided between the various slab edges so as to strengthen the joint formed therebetween.

The actual slab and beam interlocking pour utilizes, between adjacent beam supported slabs 12, the top of the beam 14 itself as the form. However, between the nonbeam supported edges of adjacent slabs 12, for example the edges indicated by reference numeral 36 in FIG. 2, an appropriate underlying forming deck 38 must be provided which can be conveniently removed after an initial setting of the pour 30. As will be best appreciated from FIGS. 1 and 2, the pour 30, for any one floor, extends peripherally about each slab, as well as within the vertical space normally provided between each upper column section 16 and the underlying beam 14, and the spaced ends of adjacent end beam sections 22. The extension of the pour between the spaced beam end sections 22, as will be appreciated, also require the utilization of some minor form work. Incidentally, it will be noted that the slab rods 34., between adjacent unsupported edges 36, cross each other and the rods and form a positive intcrlock with the pour 30 received between the edges 36.

Upon completion of the pour 30, it will be recognized that a positive binding network has been provided both about the slabs 12 and laterally between adjacent stacks throughout the full horizontal extent of each floor of the structure. The spacing of each upper column section 16, through the utilization of the vertical reinforcing rods 26, above the corresponding beam 14 is of significance in that such enables the pour 30 to extend continuously therebeneath and positively bind the adjoining slabs both to each other and to the reinforcing rods of the column portions of the tree t10.

From the foregoing, it should be appreciated that a highly unique construction system has been devised. This system enables the formation of a concrete frame building utilizing preformed or precast sections whereby the rate of construction is substantially accelerated. By the same token, the construction is such so as to provide a highly rigid structure wherein the components are positively interlocked and form what might be considered an integral structure. This is effected basically through the utilization of unique column and beam units and slabs. The column portions of the units are vertically locked to each other through grout containing sleeves. The beam portions of the units are similarly interlocked by splice sleeves or lapped splices and a portion of a continuous concrete pour which also functions so as to interlock the slabs and units and laterally tie the units together. As suggested in 'FIG. 1, the various components can be assembled through the utilization of any appropriate type of lift equipment.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be restored to, falling within the scope of the invention.
