The present invention relates generally to prefabrication systems, and, more particularly, to systems employing prefabricated planks and frames.
A major concern in building construction is minimizing costs, maintaining a safe working environment and maximizing architectural flexibility and creativity. Striking this balance is the greatest challenge faced in developing prefabrication systems. Thus far, prefabrication systems have lacked in quality because of the need to reduce the costs of the materials employed, as costs for non-standard parts, as well as labor costs for the mounting and finishing steps, tend to be very high.
Additionally, prior prefabrication systems require repetitive structural elements, which leave no space for the introduction of personalized elements during the design stage of the building. The installation difficulties faced with prefabrication systems have further contributed to the use of inflexible, repetitive components.
Assuring worker safety is a paramount concern during the construction phase of any building, particularly high-rise structures. The installation of prefabricated floor modules, as opposed to traditional stick built methods, promotes job-site safety. The assemblage of components takes place at ground level assuring that less labor is required at elevated levels. Additionally, once the modules are in-place, workers of all trades are provided an immediate platform over which they can perform their activities.
Accordingly, there exists a need for an improved prefabrication system that provides convenient, flexible components that are easily preassembled and installed.
The following presents a simplified summary of the invention in order to provide a basic understanding of some aspects of the invention. This summary is not an extensive overview of the invention. It is not intended to identify key or critical elements of the invention or to delineate the scope of the invention. Its sole purpose is to present some concepts of the invention in a simplified form as a prelude to the more detailed description that is presented later.
According to its major aspects and briefly stated, the present invention includes a prefabrication system having a floor component and a frame component. In particular, the floor component includes a deck member, which can be made of deck sections, profiles, or panels. For example, the deck member can be made of continuous panels that cover the desired width and length of the floor component. Alternatively, the deck member can be made of sections that are combined in juxtaposed relation to form the desired width and length. The frame component, which is generally rectangular shaped, includes horizontal support beam elements on three sides and a spandrel beam on the fourth side that are attached to opposing vertical columns, respectfully. The beam elements are not limited to a shape, and can be generally C or I-shaped, and include a top flange that is dimensioned to support each end of the deck member. Additionally, multiple floor and frame components can be combined to form a building having multiple rooms and levels.
The present invention further includes a method for constructing a floor using the panelization system. The steps of the method include: 1) providing vertical columns that are spaced apart so as to establish panelization system perimeters in a building construction or any particular area within a building construction; 2) providing a horizontal framing system; 3) providing a composite decking system; 4) connecting the horizontal framing system and the composite decking system to form a panelization system; 5) elevating the panelization system and positioning the panelization system between the vertical columns; 6) connecting the panelization system to the vertical columns; and 7) forming a spandrel beam system that is connected to the panelization system.
A feature of the present invention is the use of a framing system that employs the use of beam elements that are connected to vertical columns. Traditional framing systems use I-beams that span between the centerline of vertical columns to provide support for floor components. These typical framing systems impede the space for mechanical openings between the columns. By using beam elements that are connected to either side of a four-sided column, a space is created between the beam elements at the centerline of the vertical columns. This space can then be used to create flexibility in design options. As an example, the space creates open areas through the floor system for mechanical equipment items such as piping, air supply ducts, and conduit.
Another feature of the present invention is the use of a spandrel beam that maintains the depth of the floor. In steel or concrete construction, the exterior beam that extends from column to column and marks the floor level between stories is commonly referred to as a spandrel beam. Spandrel beams are employed to support non-load bearing exterior fascia elements. Spandrel beams can also support floor loads; however, this application requires additional reinforcement. Traditionally, the challenge has been in providing reinforcement to the spandrel beam without increasing the depth of the slab, thus eliminating the need for a dropped beam, which is not aesthetically pleasing. The spandrel beam of the present invention is flush with the flooring of a building. Accordingly, the spandrel system accomplishes the challenging task of supporting an exterior curtain wall, while still providing an uninterrupted ceiling at the curtain wall.
Yet another feature of the present invention is the method for constructing a floor using the panelization system. Traditional methods for construction require that individual banded bundles of floor components be lifted onto horizontal beams. The bundles are then unbanded, and individual floor component pieces are distributed over the beams elements. The individual floor components are attached to the beam elements to complete the installation. This process becomes increasingly challenging, creating additional safety issues, thus adding expense to the construction of multi-story buildings. The present invention, however, provides for the positioning of a panelization system including preassembled floor components between the vertical columns at the desired floor elevations. Accordingly, the maneuvering and installation of individual floor components is avoided. The panelization system, when installed, gives construction workers immediate access to a large load supporting platform, thereby promoting construction safety.
Other features and advantages of the present invention will be apparent to those skilled in the art from a careful reading of the Detailed Disclosure of the Preferred Embodiment presented below and accompanied by the drawings.
In the drawings,
The present invention includes a panelization system and method. As illustrated in the drawings, and in particular
A cross sectional view of the panelization system 10 as incorporated within the exemplary construction, and in particular, within the first and second zones 21, 22, is shown in
As previously described, a feature of the present invention includes the use of a frame component 14 that employs the use of horizontal beam elements 30 that are connected to vertical columns 20 or 25. Traditional systems use I-beams that are centered and span between vertical columns to provide support to floor components 12. Because of the shape of I-beams, the attachment of the beams between two columns eliminates the space 32 between the vertical columns. By using beam elements 30 that are connected to either side of a four-sided column, additional space 32 is provided between the vertical columns. This space 32 forms a voided air space that can create flexibility and be designed to allow for the vertical passage of other building trade components such as mechanical components, electrical components, etc., between floors.
By way of example and not limitation, a pourable, continuous layer of concrete 40 can be placed over the floor component 12 and within the confines of the frame component 14 to further complete the construction of the building floor. Accordingly, the frame component 14 optionally includes studs 42 extending into the concrete layer that can assist in the bonding and anchoring of the concrete to the beam elements. Furthermore, because the beam elements 30 create an open space 32 between the opposing vertical columns 20 supporting the floor component 12, a beam closure 46 can be connected to the opposing beam elements 30 to allow for the placing of a continuous layer of concrete 40. The beam closure 46 adjusts horizontally to abut beam elements 30 and seal the open space 32 during placement of the concrete 40. Additionally, a blocking 44 can be connected to opposing beam elements 30 so as to stabilize beam element 30 and provide bearing and support of beam closure 46.
The beam closure 46 can be any geometric shape, and can include a deck profile, panel, etc., attached between the beam elements 30 and atop the blocking 44 to restrict the flow of concrete 40 and seal the floor system from concrete leakage. Additionally, blocking 44 can be connected to opposing beam elements 30 so as to provide additional attachment between the beam elements 30 as needed to complete the construction. The blocking 44 can be any component installed between beam elements 30 to meet the design requirements. The continuous layer of concrete 40, can be further reinforced with the use of concrete reinforcing steel 60 such as steel sheets, bars, strips, plates, etc., that is designed and placed as needed in the flooring.
Again, by way of example and not limitation, the ceiling of the building can be formed by including furring channels 50 and gypsum board 52 attached beneath the panelization system 10. Additionally, during the construction process, temporary shoring posts 54 and beams 55 can be placed beneath the floor component 12 as shown in
An alternative embodiment of the frame component 14 is shown in
A cross sectional view of the panelization system 10 as incorporated within the exemplary construction, and in particular, within the first and fourth zones 21, 24, is shown in
The present invention also includes a spandrel beam system 15 used in connection with the panelization system 10. By way of example and not limitation, a plan view of a panelization system 10 incorporating the spandrel beam system 15 is shown in
The features of the spandrel beam system 15 are shown in detail in
A feature of the present invention includes the use of a continuous pour stop member 85 in combination with reinforcing means, including reinforcing steel 60 and rebar 61. This feature provides both positive and negative moment reinforcement, as well as diaphragm shear resistance, along the spandrel beam 15 of the panelization system 10.
As shown, the spandrel beam system 15 provides support for an exterior fascia element 150. Although other shapes and dimensions may be employed, the preferred embodiment of the spandrel beam system 15 includes an exterior fascia support, such as a ledger angle 35, that extends longitudinally along the length of the exterior fascia element 150. As illustrated, the support ledger angle 35 includes a first flange 37 and a second flange 39. Although various shapes are contemplated, the first flange 37 can be about perpendicular with the second flange 39. The first flange 37 provides a support for the exterior fascia element 150, and the second flange 39, which is adjacent to pour stop 85, provides an area of attachment to the pour stop 85. The means of supporting the exterior fascia element 150 can be completed through other designs.
Similarly, the pour stop 85 includes a first flange 87 and a second flange 86. Although various shapes are contemplated, the first flange 87 of pour stop 85 can be about perpendicular with the second flange 86. The first flange 87 of pour stop 85 is adjacent to the second flange 39 of the exterior fascia support angle 35. Furthermore, the first flange 87 of pour stop 85 establishes the boundaries of the layer of concrete 40 and prevents the layer of concrete 40 from making contact with the exterior fascia elements 150. Additionally, the first flange 87 can be used as an attachment surface for hooked reinforcing steel 60. As shown, the second flange 86 of the pour stop 85 can as an option include shear stud 42 or multiple shear studs (not shown) extending into the layer of concrete 40 that can assist in the bonding and anchoring of the layer of concrete 40 to spandrel beam system 15. The slab closure element 13, which can be any shape, including a flat strip, is used to provide connection between the pour stop 85 and the outermost section of the floor component 12. Other profile shapes can be used instead of the pour stop angle 85 described above depending on the design requirements (i.e channel shapes).
By way of example and not limitation, a feature that can be included in both a suitable floor component 12 and partition component 18 is shown in
The deck member 90 can be used to connect the floor component 12 to the frame component 14 of the present invention. As illustrated in
An exemplary attachment of the partition component 18 to the frame component 14 of the present invention is shown in
An alternative embodiment of the connection between adjacent exterior panelization systems 10 includes the use of an interior panelization system 19, as shown in
Depending on the particular design of a building, a horizontal mechanical plenum 62 can be included beneath the partition component 18 or interior panelization system 19, as shown in
The present invention further includes a method for constructing a floor using the panelization system 10. The steps of the method include: 1) providing vertical columns 20 or 25 that are spaced apart so as to establish perimeters in a building construction or room within a building construction; 2) providing the frame component 14 as previously described; 3) providing the floor component 12 as previously described; 4) connecting the frame component 14 and the floor component 12 to form the panelization system 10; 5) elevating the panelization system 10 and positioning the preassembled panelization system 10 between the vertical columns 20 or 25; 6) connecting the panelization system 10 to the vertical columns 20 or 25; and 7) forming the spandrel beam system 15 along exterior edges of building.
Those skilled in the art of panelization systems will recognize that many substitutions and modifications can be made in the foregoing preferred embodiments without departing from the spirit and scope of the present invention.
