Definitions
- the present invention relates generally to the field of structural building elements, and more particularly to a composite wall structure, methods of construction and use thereof, and components for use therein.
- retaining walls are often constructed to resist lateral pressure and prevent movement of earth behind the wall.
- Seawalls and dikes may be constructed to prevent erosion of a shoreline, to break the force of waves, and/or for aesthetic purposes.
- Barrier walls are used to restrict ingress and egress, to mark boundaries, for security, and for various other functional or decorative purposes.
- such wall structures have been constructed of masonry materials including brick, stone, block, and concrete, of wooden cross-tie members, and/or of steel or other structural materials.
- geogrid and block construction system Another alternative sometimes used to build retaining walls is the geogrid and block construction system, wherein the geogrid reinforces and stabilizes soil behind the wall. This technique reduces the load on the face of the wall and allows for alternative decorative surfaces and textures to be used. This construction technique typically requires a foundation and it can be quite costly to install the geogrid and blocks.
- sheet-piling walls and methods of construction thereof as shown for example in U.S. Pat. No. 7,059,807, U.S. Pat. No. 7,056,066, U.S. Pat. No. 7,025,539, U.S. Pat. No. 6,575,667, U.S. Pat. No. 6,053,666, U.S. Pat. No. 6,033,155 and U.S. Pat. No. 6,000,883, have been developed.
- These types of wall systems typically do not require a separate foundation, as they are not nearly as heavy as walls of masonry or most other more traditional materials of construction, and as they derive considerable lateral support and stability from being partially embedded into the ground.
- sheet-piling wall systems are frequently utilized in seawall construction and other applications in wet or otherwise unstable soils, and are generally less expensive to construct as compared with walls of masonry and many other traditional materials of construction.
- Sheet-piling wall systems typically include a number of interconnected elongate vertically-driven pile members, which results in the walls having a corrugated or horizontally segmented appearance. Consumers in the marketplace have come to accept this somewhat utilitarian appearance as a necessary characteristic of the wall's manner of construction. Moreover, the application of any sort of decorative facing to a sheet-piling; seawall system would heretofore have been considered counterintuitive to those of skill in the art, as the corrugations or seams of a standard sheet-piling wall could permit water and debris to collect in the spaces behind the facing and could permit wave action to cause detachment of the facing material.
- the present invention provides improved wall systems and components therefor, and further provides improved methods of constructing wall systems.
- Wall systems, components and construction methods according to the present invention are adaptable for use in various applications, including for example, seawalls, dikes, piers, retaining walls, barrier walls, and the like.
- the present invention is a composite wall system that includes a foundationless wall substructure having a base portion embedded in the ground, and an exposed portion not embedded in the ground.
- the composite wall system further includes a panelized fascia attached to the foundationless wall substructure over at least the exposed portion thereof.
- the foundationless wall substructure takes the form of a sheet piling wall, a driven or jetted-in-place concrete wall, vinyl pilings, fiberglass reinforced plastic (FRP) pilings, steel pilings, wood, and/or other form of wall substructure component(s) not requiring a separately formed foundation.

- the method of the invention further includes applying a panelized fascia over at least the exposed portion of the at least one substructure member.
- the invention is a method of designing and/or fabricating a composite wall system.

Abstract
Description
- This application claims the priority benefit of U.S. Provisional Patent Application Ser. No. 61/024,395 filed in the United States Patent and Trademark Office on Jan. 29, 2008, which is hereby incorporated herein by reference in its entirety for all purposes.
- The present invention relates generally to the field of structural building elements, and more particularly to a composite wall structure, methods of construction and use thereof, and components for use therein.
- Various wall structures are utilized in the building and construction trade. For example, retaining walls are often constructed to resist lateral pressure and prevent movement of earth behind the wall. Seawalls and dikes may be constructed to prevent erosion of a shoreline, to break the force of waves, and/or for aesthetic purposes. Barrier walls are used to restrict ingress and egress, to mark boundaries, for security, and for various other functional or decorative purposes. Traditionally, such wall structures have been constructed of masonry materials including brick, stone, block, and concrete, of wooden cross-tie members, and/or of steel or other structural materials.
- In many seawall and retaining wall applications, the soil is not conducive to building with heavy stones or bricks. To build a wall from these materials requires substantial excavation and a foundational footing in order to support the vertical load. This is expensive and time consuming in general, and in those applications involving proximity to water, such as a seawall, it is generally cost prohibitive. The soils underlying such applications are typically very soft because of their water saturation. Softer soils generally require a deeper and wider foundation which can increase the cost exponentially. Furthermore, excavating and pouring foundations underwater is an expensive and time-consuming process. For these reasons, seawalls and retaining walls in the vicinity of water are rarely constructed of stone, brick or other masonry materials.
- In the case of retaining walls not in the vicinity of water, and which are typically supported by harder soils, decorative materials such as stone or brick are often applied only as an aesthetic facing on the wall, and are supported by a heavy concrete sub-wall structure and foundation. Alternatively, simulated stone molded panels, for example as shown in U.S. Pat. No. 6,726,864, may be applied over a wall substructure of concrete or other structural material(s). This manner of construction generally involves significant labor and material expenses. Such walls typically require a separate and substantial underlying foundation, commonly of steel-reinforced poured concrete construction, as well as a high degree of soil stability and compaction beneath and around the wall structure to anchor and support the wall's weight.
- Another alternative sometimes used to build retaining walls is the geogrid and block construction system, wherein the geogrid reinforces and stabilizes soil behind the wall. This technique reduces the load on the face of the wall and allows for alternative decorative surfaces and textures to be used. This construction technique typically requires a foundation and it can be quite costly to install the geogrid and blocks.
- Further improvements have been made in the field of wall structure construction. For example, sheet-piling walls and methods of construction thereof, as shown for example in U.S. Pat. No. 7,059,807, U.S. Pat. No. 7,056,066, U.S. Pat. No. 7,025,539, U.S. Pat. No. 6,575,667, U.S. Pat. No. 6,053,666, U.S. Pat. No. 6,033,155 and U.S. Pat. No. 6,000,883, have been developed. These types of wall systems typically do not require a separate foundation, as they are not nearly as heavy as walls of masonry or most other more traditional materials of construction, and as they derive considerable lateral support and stability from being partially embedded into the ground. As a result, sheet-piling wall systems are frequently utilized in seawall construction and other applications in wet or otherwise unstable soils, and are generally less expensive to construct as compared with walls of masonry and many other traditional materials of construction.
- Sheet-piling wall systems typically include a number of interconnected elongate vertically-driven pile members, which results in the walls having a corrugated or horizontally segmented appearance. Consumers in the marketplace have come to accept this somewhat utilitarian appearance as a necessary characteristic of the wall's manner of construction. Moreover, the application of any sort of decorative facing to a sheet-piling; seawall system would heretofore have been considered counterintuitive to those of skill in the art, as the corrugations or seams of a standard sheet-piling wall could permit water and debris to collect in the spaces behind the facing and could permit wave action to cause detachment of the facing material.
- In example embodiments, the present invention provides improved wall systems and components therefor, and further provides improved methods of constructing wall systems. Wall systems, components and construction methods according to the present invention are adaptable for use in various applications, including for example, seawalls, dikes, piers, retaining walls, barrier walls, and the like.
- In one aspect, the present invention is a composite wall system that includes a foundationless wall substructure having a base portion embedded in the ground, and an exposed portion not embedded in the ground. The composite wall system further includes a panelized fascia attached to the foundationless wall substructure over at least the exposed portion thereof.
- Optionally, the foundationless wall substructure takes the form of a sheet piling wall, a driven or jetted-in-place concrete wall, vinyl pilings, fiberglass reinforced plastic (FRP) pilings, steel pilings, wood, and/or other form of wall substructure component(s) not requiring a separately formed foundation. The fascia optionally takes the form of a synthetic molded panel having a simulated stone work, simulated brick work, or other aesthetically appealing outer surface.
- In another aspect, the invention is a composite wall system including a sheet-piling substructure incorporating a plurality of elongate pile members, each pile member having at least one engagement member for connection with an adjacent pile member. The composite wall system also includes a fascia panel for application over at least a portion of the sheet-piling substructure. The fascia panel has an inner face for attachment to the sheet-piling substructure, and a decorative outer face.
- In still another aspect, the invention is a cap member for a composite wall system, the cap member including an upper panel and a front panel, the upper panel and the front panel each having an inner portion for engagement with a substructure, and an outer portion including a decorative surface.
- In another aspect, the invention is a method of fabricating a composite wall system. The method of the invention includes driving at least one substructure member partially into the ground, whereby the substructure member defines an embedded portion within the ground and an exposed portion above the ground. The method of the invention further includes applying a panelized fascia over at least the exposed portion of the at least one substructure member.
- In yet another aspect, the invention is a method of designing and/or fabricating a composite wall system. The method of the invention includes providing at least one substructure member having an outer attachment surface, and providing at least two types of fascia panel. A first of the at least two types of fascia panel has a first decorative appearance, and a second of the at least two types of fascia panel has a second decorative appearance different from the first decorative appearance. The method of the invention further includes selecting one of the at least two types of fascia panel for attachment to the outer attachment surface of the substructure member.

Optionally, awale fascia strip 575 is applied to cover underlying wall elements or material transitions, for decorative purposes and/or for resisting intrusion of debris and wave action. -
FIG. 7 shows awall 610 according to another embodiment of the invention. The underlying wall substructure comprises a plurality ofsheet piling members 616, each defining a retainingslot 615, and optionally having a series of vertically spaced receiver openings 617 therein. Astarter strip 625 is affixed to thesheet piling members 616 at about (or just below) the mean low water level for seawall applications, and at about (or just below) the soil level for retaining wall applications. A plurality of fascia panel elements ormodules 630 are affixed to thesheet piling members 616 above thestarter strip 625. Each of thefascia panel modules 630 has a generally S-shaped or Z-shaped profile comprising an upper rectangular portion and a lower rectangular portion, the upper and lower rectangular portions being partially horizontally offset from one another and joined at a medial portion, such that adjacent fascia panel modules interlock or combine to form a substantially continuous surface. Each fascia panel module can include an outer face molded to present the appearance of one or more stones, bricks, blocks or other building components, and fascia panel modules having two or more complementary patterns can be provided to present a more continuous or evenly distributed visual appearance (i.e., to break up or disguise the repeating pattern of the fascia modules). The starter strip may include sealing means for preventing debris and/or water from entering between the sheet piling members and the fascia panel modules, can provide a horizontal reference line for alignment of the first course of fascia panel modules during installation, and/or can provide attachment between the fascia panel modules and the sheet piling members. Acap member 650 is optionally provided along the upper ends of thesheet piling members 616. Thefascia panel modules 630, and optionally also thestarter strip 625, are affixed to thesheet piling members 616 by mountinglugs 635 projecting from the back faces of the fascia panel modules. Thelugs 635 are engaged and retained in the retainingslot 615 by means of interengaging male and female profiles. In alternate forms, the lug-and-slot coupling system is reversed, with the lugs comprising projections from the sheet piling members or other wall substructure, and the slots being formed in the fascia panel(s). In assembling thewall 610, thesheet piling members 616 are driven into the ground in typical fashion. Thestarter strip 625 is installed onto the sheet piling members at the desired level, for example at a true horizontal. Thefascia panel modules 630 are attached by inserting thelugs 635 into theslots 615, as by sliding the fascia panel modules down from the top of the sheet piling members, or by insertion of the lugs into receiver openings 617 (if provided) near the desired point of attachment and sliding them up or down in the slots for final placement. Additional attachment may optionally be provided between the fascia panel modules and the sheet piling members, for example by means of adhesive, screws or other fasteners, clips, integral snap couplings, or the like. Thecap member 650 may be engaged by one or more couplings or other attachment means, to prevent upward movement and possible detachment of the fascia panel modules. - In its various example embodiments, the composite wall system of the present invention may be fabricated by driving one or more substructure members partially into the ground. In example forms, the substructure members take the form of sheet piling members or wall panel components. An embedded portion of the wall substructure serves to anchor the wall in the ground and resist lateral forces. An exposed portion of the wall substructure extends a distance above the ground. Anchor bars and/or tie rods may be installed to reinforce the wall substructure. One or more panelized fascia members are then applied over at least the exposed portion of the wall substructure. In example forms, the panelized fascia members take the form of sheet-like or strip-like synthetic moldings or extrusions formed of polymeric, ceramic, masonry, and/or composite material(s), and having a simulated stone, brick, or other aesthetically appealing outer surface contour and texture. The fascia members can be affixed to the underlying wall substructure by adhesive, connection strips, screws, clips, integrally formed engagement members, and/or other permanent or semi-permanent fasteners or attachment means. Optionally, one or more bumpers or wale members are affixed to the wall substructure, to the fascia panel, or are integrally formed as part of the fascia panel. A cap member is optionally installed over the top of the wall substructure and panelized fascia members, and in example embodiments serves as an attachment mechanism to join the substructure and fascia and/or serves to prevent water or debris from entering therebetween.
- The invention also includes methods of designing and fabricating composite wall systems, wherein multiple different types of fascia panels are provided for attachment to an outer attachment surface of underlying substructure members. For example, a first type of fascia panel can comprise an outer surface having a first decorative appearance in the form of simulated stonework, and a second type of fascia panel can comprise an outer surface having a second decorative appearance in the form of simulated brickwork. Alternatively, the first and second decorative appearances can be stonework or brickwork of differing colors, differing tones, differing geometric configurations or sizes, differing textures, or various other differing decorative appearances. The first and second types of fascia panels, however, will both be compatible for attachment to the common shared form of underlying wall substructure elements. A designer will then specify or select one or more of the multiple different types of fascia panels for attachment to the wall substructure. The design and fabrication methods according to the present invention can optionally further comprise the provision of different types of cap members, each type having a differing outer surface appearance; the provision of different types of bumper or wale members, each type having a differing outer surface appearance; and/or the provision of different types of other wall system components, each type having a differing outer surface appearance, whereby the designer specifies or select one or more of the different types of wall system components for attachment to the wall substructure.
- While the invention has been described with reference to preferred and example embodiments, it will be understood by those skilled in the art that a variety of modifications, additions and deletions are within the scope of the invention, as defined by the following claims.
