Description

TECHNICAL FIELD

The disclosure generally relates to a method, apparatus, and system for fabricating a structure.

BACKGROUND

Various methods can be employed to fabricate and construct multi-story buildings. Traditionally, multi-story buildings have been constructed from the ground up, in which construction of the building begins on a ground level by attaching higher elevation structural elements on top of previously assembled lower structural elements to construct the building in upward direction, i.e., from bottom up. Such methods may be inefficient in terms of material handling and placement. Presently, structural framing elements may be assembled into a building frame one member at a time and above ground level. Tower cranes are used during construction to execute thousands of individual lifts for elements of the structure, building enclosure, finishes, mechanical and electrical equipment and many other components of a finished building. Furthermore, concrete or another hardenable material is pumped to the final elevation of each floor. These operations may require specialized equipment and setup logistics, and may be time-consuming and labor-intensive when constructing multi-story buildings.

There is a need to provide a building fabrication method and system, and an associated fabricated building, that more effectively uses available material and labor resources.

Referring to the Figures, wherein like numerals indicate like parts throughout the several views, FIG. 1 shows a vertical support core 10 for a building 100 that is arranged on a base 12, wherein the building 100 is fabricated employing a top-down construction process. In general, the top-down construction process includes sequentially constructing a plurality of floor plates 50 at an assembly level 25, lifting each of the floor plates 50 to a respective design elevation 15, and attaching each of the floor plates 50 to the vertical support core 10 of the building 100 in a descending order. The building 100 includes a single vertical support core 10 as shown with reference to FIG. 1, or multiple vertical support cores 710, 721 as shown with reference to FIG. 6, and a plurality of the floor plates 750.

As used herein, the term “floor plate 50” includes but is not limited to all structural or frame members, e.g., joists and/or purlins; flooring, e.g., concrete floor; interior walls; exterior curtain walls; modular room subassemblies; lavatories; mechanical building elements 70 (shown with reference to FIG. 4) etc., that form a floor or level of the building 100. The term “floor plate 50” may include a plate for a roof structure (not shown) of the building 100, as well as a plate for a floor or level of the building 100. Accordingly, the term “floor plate 50” is used herein to refer to both the roof structure for the roof of the building 100, as well as a floor structure for one of the floors or levels of the building 100. The reference numeral 50 may refer to and indicate any floor plate 50 of the building 100. The floor plate 50 specifically includes a floor plate frame 51, which is described herein.

Referring again to FIG. 1, the construction system includes the vertical support core 10, which is an element of a vertical slip form system. The vertical support core 10 is formed from multiple vertical load-bearing columns formed from steel beams, cross-members, and outer shear walls that are formed from a hardenable material. The vertical support core 10 also includes a plurality of horizontal roof beams 14 that are arranged on a top portion 13. The vertical support core 10 is designed to carry the vertical loads of the building 100. As such, the shape of the vertical support core 10 may be designed as necessary to provide the required compressive strength, shear strength, and bending strength for the particular application, size, and location of the building 100.

The hardenable material may include, but is not limited to, a concrete mixture or other similar composition. The hardenable material may include one or more additives to enhance one or more physical characteristics of the hardenable material, such as to reduce curing time, reduce slump, increase strength, etc. The specific type and contents of the hardenable material 64 may be dependent upon the specific application of the building 100, and may be dependent upon the specific geographic region in which the building 100 is being constructed. The specific type and contents of the hardenable material are understood by those skilled in the art, and are not described in detail herein.

A plurality of lift jacks 16 are attached to the roof beams 14 of the vertical support core 10, and are employed to lift the floor plates 50 to their respective design elevations 151, which is illustrated in dashed lines. Referring again to FIG. 1, the lift jacks 16 may include, but are not limited to a plurality of strand jacks. Alternatively, the lift jacks 16 may include other devices capable of lifting each of the floor plates 50 of the building 100. Strand jacks are able to grasp and move a cable to lift heavy objects. The specific features and operation of lift jacks 16 such as strand jacks are known to those skilled in the art. The lift jacks 16 couple to a bridle 30 via cables 18 and lockable joints 20.

As shown, each of plurality of the floor plates 50 can be assembled on the bridle 30, which is placed at an assembly level 25 that is at or proximal to ground elevation. The plurality of the floor plates 50 are lifted to their respective design elevations 151 relative to the vertical support core 10 in a sequential descending order employing the lift jacks 16.

The bridle 30 is arranged around an outer periphery of the vertical support core 10 and is attachable to and suspended from the lift jacks 16 via cables 18 and lockable joints 20. The bridle 30 is a reusable device that can be employed to support each floor plate 50 during assembly at the assembly level 25. The bridle 30 is also used to support each floor plate 50 when the respective floor plate 50 is being lifted by the lift jacks 16 and secured to its respective design elevation 151. The bridle 30 is lowered by the lift jacks 16 to the assembly level 25 after the respective floor plate 50 is secured to its respective design elevation 151. The bridle 30 is then re-used to support another of the floor plates 50 during assembly. As shown with reference to FIG. 4, the bridle 30 is supported on a plurality of stub columns 22 that are arranged on the base 12 around the outer periphery of the vertical support core 10 when it is at the assembly level 25 proximal to the ground elevation.

FIG. 2 schematically illustrates a top plan view of an embodiment of the bridle 30 and the vertical support core 10 arranged on the base 12. Elements of the vertical support core 10 include a first side 24, a second side 26, a first end 27, and a second end 28. The bridle 30 includes lifting beams 32 and side beams 38 that are arranged around the outer periphery of the vertical support core 10. The lifting beams 32 are attached to and suspended from the lift jacks 16. When the vertical support core 10 has a rectangular cross-section, e.g., as shown, a first of the lifting beams 32 is suspended from a first set of the lift jacks 16 on the first side 24 of the vertical support core 10, and a second of the lifting beams 32 is suspended from a second set of the lift jacks 16 on the second side 26 of the vertical support core 10 that is opposite to the first side 24. A first of the side beams 38 is arranged on a first end 27 of the vertical support core 10 and is connected to first ends 34 of the lifting beams 32. A second of the side beams 38 is arranged on a second, opposite end 28 of the vertical support core 10 and is connected to second ends 36 of the lifting beams 32. The side beams 38 and the lifting beams 32 are arranged such that upper surfaces of the opposed lifting beams 32 are level with upper surfaces of the opposed side beams 38 in a horizontal plane. A plurality of bearing pads 44 are assembled onto the first and second side beams 38 for placement of girders 52, 53 (as best shown with reference to FIG. 3) of the floor plates 50 during assembly. Alternatively, the plurality of bearing pads 44 can be assembled onto the first and second lifting beams 32 for placement of the girders 52, 53 of the floor plates 50 during assembly.

The floor plates 50 make up discrete sections of the building 100. Each of the floor plates 50 is assembled at the assembly level 25, which is advantageously a few feet above ground level on top of the bridle 30. Each of the floor plates 50 is lifted to its design elevation 151 employing the lift jacks 16 or other vertical conveyance structure(s), and permanently affixed to and supported by the vertical support core 10. The floor plates 50 are cantilevered from the lift jacks 16 and therefore, the weight of each of the floor plates 50 is best distributed symmetrically around the vertical support core 10 and the lift jacks 16. The floor plates 50 may be designed asymmetrically around the lift jacks 16 so long as proper design and loading techniques are utilized.

Referring now to FIG. 3, a top-side perspective isometric view of a cutaway of an embodiment of the floor plate 50 is shown. The floor plate 50 has a floor plate frame 51, which is a woven structure that is assembled and is in the form of main framing members e.g., first and second girders 52, 53, a plurality of transversely-oriented continuous framing members 54, and in one embodiment, spandrels 55. Sidewalls 60 including walls, glass, windows, decks, railings, etc., are assembled to the spandrels 55. The girders 52, 53 are supported on the plurality of bearing pads 44 that are assembled onto the first and second side beams 38 of the bridle 30. The continuous framing members 54 are arranged to penetrate the first and second girders 52, 53 and are supported at multiple points with preset cambers. Camber is defined as a deviation from a flat, level, horizontal plane. Each of the continuous framing members 54 is an assembled part that includes a medial beam 56 and first and second cantilevered beams 57, 58. This arrangement results in a floor assembly that is strong, and thus can be exploited to reduce beam depth without increasing vertical deflection. The floor plate frame 51 imparts precise amounts of camber at junctions. The junctions may be formed employing friction bolts and plates at inflection points to meet camber requirements. The combination of bolted, four-sided junctions in the floor plate frame 51 creates an efficient and flexible roof and floor plate structure that may be adjusted for camber control during assembly. The floor plate frame 51 maximizes the strength of the transverse members, e.g., framing members 54, permitting beam depth to be minimized. Weight and overall depth of the floor plates 50 is thereby minimized. Furthermore, openings in first and second girders 52, 53 that permit the transversely-oriented framing members 54 to penetrate are cut to close tolerances, providing bracing at locations of penetrations. This bracing may prevent unintended rotation of the transverse members during assembly even before any junctions have been installed.

FIGS. 1-4 show various features of the building 100, the vertical support core 10, the bridle 30, and the floor plate 50 when disposed at the assembly level 25 near the ground elevation 14. The floor plate 50 includes the first and second girders 52, 53 that are arranged in parallel and slidably disposed on opposed sides of the vertical support core 10 in a manner that permits and facilitates vertical conveyance. Each of the first and second girders 52, 53 includes a vertically-oriented web portion and a flange portion. The first and second girders 52, 53 may each be configured, by way of non-limiting examples as an I-beam, a C-beam, a T-beam, an L-beam, a square beam, a rectangular beam, etc., and are fabricated from steel in one embodiment. A plurality of apertures are formed in the vertically-oriented web portions, and are configured to accommodate insertion of one of the first and second cantilevered beams 57, 58. The first and second girders 52, 53 are disposed on bearing pads 44 of the side beams 38 of the bridle 30, which is resting on a plurality of stub columns 22 that are disposed on an assembly pad that is fabricated on the base 12.

A plurality of the continuous framing members 54 are disposed transverse to the first and second girders 52, 53. Each of the framing members 54 includes the medial beam 56 that is attached to the first and second cantilevered beams 57, 58, and is arranged transverse to and supported by the first and second girders 52, 53. The medial beam 56 and the first and second cantilevered beams 57, 58 are each configured to have a flat beam section on a top portion of the respective beam along its longitudinal axis. The medial beam 56 may be configured as an I-beam, a C-beam, a T-beam, an L-beam, a square beam, a rectangular beam, etc., which defines a respective cross-sectional shape. The medial beam 56 includes first and second ends, with a plurality of bolt through-holes disposed thereat. Each of the first and second cantilevered beams 57, 58 may be an I-beam, a C-beam, a T-beam, an L-beam, a square beam, a rectangular beam, etc., which defines a respective cross-sectional shape.

The cross-sectional shape associated with the first cantilevered beam 57 corresponds to a respective aperture in the first girder 52, and the cross-sectional shape associated with the second cantilevered beam 58 corresponds to a respective aperture in the second girder 53. The medial beams 56 are horizontally disposed between the first and second girders 52, 53. The length of each of the medial beams 56 is selected to define inflection points. Distal ends of the first and second cantilevered beams 57, 58 are attached to spandrels 55 in one embodiment. Distal ends of the first and second cantilevered beams 57, 58 may be supported on pedestals 17, which can be installed on the base 12 and height-adjusted as required to maintain the required geometry during assembly of the floor plate 50 and placement and curing of the hardenable material 64. When each of the floor plates 50 is lifted and locked into its permanently supported position at its design elevation 151, the achieved flatness is measured and outcomes may be used to adjust the geometry of the next one of the floor plates 50 being fabricated. This process improves the flatness tolerance of each successive floor plate.

FIG. 3 further shows a cutaway portion of the metal decking 62 that is attached onto the floor plate frame 51. The metal decking 62 provides a lower plate on which hardenable material 64 can be poured during fabrication. This approach to assembling the floor plate 50 may achieve improved surface flatness tolerances by facilitating the accurate simulation of each floor plate's permanent support condition of during grade-level fabrication.

FIG. 4 provides a bottom-side perspective isometric view of the building 100 including vertical support core 10, bridle 30, and floor plate 50 including metal decking 62 at the assembly level. The bridle 30 is resting on stub columns 22 that are arranged on the base 12.
