FIELD OF THE INVENTION
The present invention relates generally to flood barriers, and, more particularly, relates to a support structure for supporting flood panels that form a flood barrier and prevent water intrusion.
BACKGROUND OF THE INVENTION
Water intrusion into buildings and structures due to flooding is responsible for a large amount of property damage. Flooding occurs as a result of rain, snow melt, and storm surge along coastlines, among other causes. As a result, flooding can occur in many different places in both rural and urban locations. In general, barriers have proven to be very effective at protecting property from flooding. There are numerous kinds of barriers, from sand bag barriers to earthen dykes with mechanically stabilized soil, and in many places panel systems are used. A panel system is a series of water-impermeable panels that are mounted to, or adjacent to a building or structure, and to the ground surface around the building or structure, in a substantially water tight arrangement. These barrier systems typically require angled braces for structural support on the back side (facing the building or structure being protected) to ensure the panels are not pushed inward and defeated by the water pressure during a flood event. This results in a minimum distance being necessary between the back of the panel barrier and the structure in order to fit the braces in between the panels and the building or structure. Also, the panels are typically connected using bolts and nuts, which are time-intensive to assemble and disassemble. As a result, when an event arises that may produce flooding, there is a limited time to set up barriers, and often limited space in which they can be set up.
Therefore, a need exists to overcome the problems with the prior art as discussed above.

DETAILED DESCRIPTION
While the specification concludes with claims defining the features of the invention that are regarded as novel, it is believed that the invention will be better understood from a consideration of the following description in conjunction with the drawing figures, in which like reference numerals are carried forward. It is to be understood that the disclosed embodiments are merely exemplary of the invention, which can be embodied in various forms.
FIG. 1 shows front perspective view of a flood panel barrier system 100 having a support structure in accordance with some embodiments. A flood panel is a discrete section of a barrier that is connected to adjacent panels in a series around a structure, or across an opening or openings in the structure through which water could enter the structure, such as doors, for example. Each of the panels is also connected to a hardened and generally level ground surface, such as concrete, and which also acts as a water barrier. At the ends of the barrier system, the end panels can be connected vertically to a wall or other portion of the structure being protected, or the panels can be arranged in a ring around the structure without being connected to the structure. All of these connections are substantially water tight, and prevent water on the outside of the barrier from passing to the inside of the barrier system, where the structure being protected is located.
In addition to FIG. 1, FIG. 2 shows a front elevational view of a section of a flood panel barrier system, and reference to both of these drawings should be made in the following discussion. A series 102 of panels 104 are connected together across an opening in the structure 108 behind the panels 104. In this case, the opening is window system 106 that extends to the ground 110, which is a bricked surface here. Each of the panels are rigid members that have a water-impermeable construction, and are configured to withstand the pressure of water against them at one side, and not buckle or otherwise substantially deform. The panel 104 at the end, our outer edge of the series 102 of panels, where the wall 108 is located, includes a side extension 109 that is connected to a flange 122 in a water tight manner. The flange 122 is parallel to the front surface of the building 108, or a sufficient portion thereof, and pressed against the building, with a gasket member 120 between the flange 122 and the building. The gasket member 120 is compliant and compressible and forms a substantially water tight seal between the flange 122 and the building 108. Likewise, across the bottom of the panels 104, at their front side, is an angled plate 114 that is a rigid elongated angled plate having one portion (114b) configured to interface with the ground surface 110, and another portion (114a) at a right angle that is configured to interface with one or more of the panels 104. A front ground gasket 116 sits under the angled plate 114 and extends under the panels 104 as well. Fastening units 112 are provide along the length of the angled plate 114 in both portions 114a, 114b. The fastening units 112 in portion 114b fasten the panel system to anchors in the ground, while the fastening units 112 in portion 114a join the angled plate 114 to the panels 104, and to other portions of the system 100. Each fastening unit 112 includes a bolt member that extends through an opening in the angled plate 114. Along portion 114a the bolt passes through the panels 104 as well, and into a rivet nut on the other side of the panel 114. Along portion 114b the bolts pass through the gasket 116 and into an anchor that is embedded in the ground surface 110. More detail of the fastening units will be discussed in regard to FIG. 3. The fasting units bear against the top side or surface of portion 114b and front side of portion 114a.
In the series 102 of panels 104, the panels 104 are joined to vertical support member 118 at the edges of the panels 104. For the sake of terminology herein, a “side” of a panel 104 refers to one of the two major surfaces, i.e. the front side and the back side. The front side faces outward from the building and the back side faces toward the building, although the panels 104 can be reversible so the front and back sides aren't defined until the panels are installed in the series 102. The panels also have edges where the sides end. The edges also define surfaces of the panels, but these surfaces are very small (in area) compared to the front and back side surfaces.
As show herein FIGS. 1 and 2, the panels are rectangular, and have two opposing vertical edges, a top edge along the top of the panel, and a bottom edge along the bottom of the panel. The bottom edge of each panel 104 rests on the bottom gasket 116. Since the panels 104 are rectangular, and homogenous in construction, their orientation may be dictated by the row of openings adjacent opposite vertical edges; the top edge is therefore whichever edge is oriented to the top of the panel 104 when the panel is installed, and likewise, the bottom edge is defined at installation. Fastening units 112 along the bottom portion 114b of the angled plate 114 compress the panels against the gasket 116 to form a substantially water tight seal along the bottom edge of each of the panels 104. The vertical support member 118 sits immediately behind, and in contact with the back sides of the panels 104 adjacent a vertical edge to connect the panels 104 together via the vertical support members 118. Several fastening units 112 are coupled through the panels and to the vertical support members 118. The vertical support members 118 are also fastened to the ground surface 110, as will be explained in more detail herein. The panels 104, being arrange in a series 102, define edge to edge interfaces where the vertical edge of one flood panel is adjacent to the vertical edge of another flood panel. The vertical support members 118 are positioned at these edge-to-edge interfaces.
FIG. 3 shows an exploded view of a fastener unit 112 for use with the inventive flood panel barrier system support structure, in accordance with some embodiments. The fastener unit 112 include a bolt 300 which can be a tap bolt. The bolt 300 includes a threaded shank 302 and a head 304 that can be a hex-head, as is well known. An adjustment knob 306 has a threaded through-hole 308 to allow the adjustment knob 306 to thread onto the shank 302 of the tap bolt 300. The main body 309 is puck-shaped and can be knurled or fluted around the outside edge to allow for turning the knob 306. The knob 306 further includes a standoff 310 that can also be puck-shaped, with have smaller diameter than the main body 309, and through which the threaded hole 308 also passes. The bottom of the standoff portion 310 of the knob 306 bears against a washer 312 to exert a compressive force, which has an opening 314 that is slightly larger than the outside diameter of the shank 302 of the bolt. Thus, the shank 302 can pass through the washer 312 without having to be threaded through the washer 312. The washer 312 can be a dock washer and have a diameter of about three inches in some embodiments. The bolt 300 can have a length of four to six inches, such as a ⅜″×4″ tap bolt. The knob 306 and washer 312 are positioned on the outward facing side of the panels so that personnel can easily access and tighten or loosen the knobs 306 of each fastener unit 112. The bolt shank 302 passes through the angled plate 114, and/or a panel, or the vertical support member 118, depending on where it is located. The distal end of the shank 302 threads into either a rivet nut 316 or an anchor 324, depending on the location of the fastening unit 112. The rivet nut 316 includes a threaded body 320 into which the shank 302 is threaded. A flange 318 extends outward and acts like a washer. There is a collapsible portion 322 that collapses when the bolt is tightened while the flange 318 is bearing against a surface, causing sections of the collapsible portion to collapse and extend outward. The anchor 324 can be a snake anchor and is intended to fit into a bore, such as a bore into the ground surface 110, and frictionally engage the sides of the bore so as to become stuck fast in the bore. This can occur, for example, by making the inner diameter of the axial bore 326 slightly smaller than the outside diameter of the shank 302 of the bolt 300, and the outside diameter of the body 328 of the anchor about the same as the diameter of the bore into which the anchor 324 is sunk. Thus, when the bolt 300 is threaded into the axial bore 326, it will force the body 328 outward against the wall of the bore in which the anchor 324 is sunk. Fastening units that secure the panels to the vertical support members of the vertical portion of angled plates can be referred to as panel fastening units and use the rivet nut 316. Fastening unit that secure the horizontal portion of angled plates to the ground can be referred to a ground or plate fastening units and use an anchor 324.
FIG. 4 shows a top plan view of flood panel barrier system where two panels 104 meet, and the inventive support structure used to hold the panels in place, in accordance with some embodiments. Reference should be made to FIGS. 5-7 here as well as they show the vertical support member 118 coupled to the ground surface in a top plan view, side elevational view, and perspective view, respectively.
A vertical support member 118 is a vertically elongated “I” or “H” beam that extends substantially from the ground surface upwards. In most cases the beam will extend to the top edge of the panels 104. The vertical support member 118 has a horizontal cross section in the shape of an “I” or “H” configuration, and includes front wall 402 that engages the back sides of the panels 104. From the front wall 402 there is a central wall 404 extending from the center of the front wall 402 at a right angle to the back wall 406. The “I”/“H” configured vertical support member 118 is one example of a possible configuration of a vertical support member in general.
A series of fastening units 112 are placed along the side of the panels 104 in a vertical series. Each one of the fastening units includes a bolt that passes through the panel 104 and the front wall 402 of the vertical support member 118, and are anchored to a rivet nut 316. Between the front wall 402 of the vertical support member 118 and the back side of the panel 104 there is a panel gasket 408. The gasket 408 is elongated in the vertical direction, and planar between the panels and the front wall 402 of the vertical support member 118, and extend from the ground surface, or from the horizontal gasket 116.
In FIGS. 5-7 it can be seen that there are angled plates 502 fitted into the bottom of the vertical support member 118 on each side of the opposing sides of the central wall 404, and between the front wall 402 and the back wall 406, and against the central wall 404. This arrangement “sandwiches” the bottom of the vertical support member between the opposing angled plates 502. The angled plates 502 have a horizontal portion 504 that interfaces with the ground surface 110 and sits on a planar horizontal gasket 508. The angled plates also have a vertical portion 506 that is against (in contact with) the central wall 404 of the vertical support member 118. Both the horizontal and vertical portions 504, 506 are as wide as the space between the front wall 402 and the back wall 406 of the vertical support member. Thus, the angled plates 502 fit tightly into the vertical support member 118. A fastening unit 112 is placed on each angle plate 502 at the horizontal portion 504, and the bolt 300 of each of those fastening units passes through the horizontal portion 504, the gasket 508, and into an anchor 324 that is sunk into the ground surface 110. The angled plates 502 when arranged and anchored to the ground surface as shown, hold the vertical support member 118 upright, and resist movement of the vertical support member 118 due to the vertical portions 506 bearing against the walls 402, 404, 406 of the vertical support member 118. This arrangement eliminates the need for an angled support behind the vertical support member. Meaning, a beam or post extending from the back wall of the vertical support member 118 to the ground surface at a distance away from the vertical support member, is not needed in at least some applications. An angled support member can still be used in some application, however. It will be appreciated that FIG. 7 is a sectional view, where a portion of the barrier system to the left and right of the vertical support member 118 have been removed to show the angled plate 502 at the bottom of the vertical support member 118. Further, a portion of the barrier system above a vertical plane section has been removed so that components of the connecting members can be more easily seen in detail.
FIG. 8 shows a detail perspective view of the lower portion of a flood panel barrier system and an end of the barrier, in accordance with some embodiments. In this example a vertical support member 118 is used at the end of a flood panel barrier system to connect to a vertical wall of a structure in a water ingress resistant manner. As with FIG. 7, the portion shown here in FIG. 8 is a section view with substantial portions of the barrier system removed from the view to better show the details being described here. The arrangement here is similar to that of FIG. 7, where there are angle plates 502 on each side of the bottom of the vertical support member to hold the bottom of the vertical support member 118 in place and to help it resist movement. However, the back wall 406 of the vertical support member is interfaced to a vertical surface of the structure through a gasket 802. The surface can be, for example, the outside wall of the structure. Fastening units 112 anchor the back wall 406 of the vertical support member to the structure. In addition, only one panel 104 is attached to the front wall 402 of the vertical support member 118.
FIGS. 9A and 9B show detail perspective view of vertically joining panels 104a, 104b in a flood panel barrier system, in accordance with some embodiments. Although a single panel 104 can be as much as four feet high, a higher barrier may be desired or needed in some applications. In each drawing there is a lower panel 104b and an upper panel 104a. Opposing angled plates 114 can be used to interface these panels 104a, 104b in a vertical manner. An upper angled plate is positioned at the bottom of the upper panel 104a, and an inverted angled plate 114 is positioned at the top of the lower panel 114b. A gasket 116 sits between the horizontal portions of the angled plates 114 and the panels 104a, 104b. Fastener units 112 are used to fasten the horizontal portions of the angle plates together (to each other) and the vertical portions of the angled plates 114 to the respective panels 104a, 104b. As in FIG. 1, the angled plates 114 extend across the entirety of the panels 104 in the horizontal direction.
FIG. 10 shows a top plan view detail of a flood panel barrier system where two panels meet, in accordance with some embodiments. FIG. 11 shows the same section, from a perspective view, with the side and upper sections of the panels removed. The embodiment illustrated here is substantially similar to the embodiment of FIGS. 4-7, with the difference being that the vertical support member 1002 is “T” shaped instead of “I” or “H” shaped in its horizontal cross section. That is, the vertical support member 1002 has a front wall 1006 and a central wall 1004 that extend from the front wall 1006 at a right angle, and is centrally located along the width of the front wall 1006 in the horizontal direction. The same angled plated 114 are used at the front bottom of the panels 104, the same gaskets 408 can be used between the panels 104 and the front wall 1006 of the vertical support member 1002, the same angled plates 502 can be used at the bottom of the vertical support member 1002 to bear against the front and central walls 1006, 1004, and the same fasting units 112 are provided in the same locations, generally. When the water level at the front of the panels 104 rises, the pressure at the bottom of the panels is greatest, and pushing in a direction from the front to the back. This tends to counteract the force of the water against the vertical support member 1002 through the barrier system, because of the vertical portions 506 of the angled plates 502 bearing against the back side of the front wall 1006 of the vertical support member 1002 resists any tendency of the vertical support member 1002 to lean to the back.
FIGS. 12A and 12B show detail perspective view of end panels of a flood panel barrier system and different wall connections, in accordance with some embodiments. These details are similar to that of FIG. 8, but do not use a vertical support member to connect to the wall of the structure. Rather, the fastening units 112 on the vertical side of the panel 104 use anchors that are embedded in the wall of the structure. In FIG. 12A there is a spacer 1202 between the panel 104 and the gasket 408, and in FIG. 12B the spacer 1202 is not used. These simply show another way that the barrier system can be terminated at one end of the barrier system.
FIG. 13 shows a detail perspective view of a section of a flood panel barrier system configured for a stair step, or similar change in elevation of the ground surface, in accordance with some embodiments. This also shows a third alternative of a vertical support member, which here is created by using two angled plates 1302, 1304 with a gasket 1306 between them. The angled plates 1302, 1304 can be substantially the same as angled plates 114, but are oriented vertically in their elongated direction. The two angled plates 1302, 1304 act substantially like a “T” shaped vertical support member as in FIGS. 10-11. However, this arrangement allows the angled plates 502 at the bottom of the vertically oriented angled plates 1302, 1304 to be at the different elevations, just as the angled plates 114 are at different elevations on each side of the gasket 1306.
FIG. 14 shows a side sectional view of a flood panel barrier system taken vertically through a panel section in which there is a cap system placed over the top of the panel(s), in accordance with some embodiments. FIG. 15 shows a front detail perspective view of a portion of a flood panel barrier system having a cap system. In this embodiment a cap is placed over the top of the panel to help increase its rigidity and prevent any tendency of the panel to bow outward from pressure created by water on the outside of the panel during a flood event. FIG. 14 shows the top edge of a panel 104, which has a first cap member 1402 across the front of the panel 104 along the top edge, with an overlapping portion over the top edge. Likewise, cap member 1404 runs along the back side of the panel 104 along the top edge, and has a portion that overlaps along the top of the panels 104. In fact the cap members 1402, 1404 can breach the separation between the panels. The fastening units 112 can use knobs 306 on both sides of the panels to counter tighten against the cap member 1402, 1404.
FIG. 16 shows a rear perspective view of a flood panel barrier system including a support brace, in accordance with some embodiments. In this embodiment the “I” or “H” vertical support member 118 is used, as in FIGS. 4-8. In some cases, where space allows behind the barrier, and angled support may be desirable to resist excessive forces against the barrier. For example, in flooding event caused by heavy rains, generally only water pressure will bear against the panels 104. However, in situations such as storm surge, then there can be a current that increases the pressure against the panels, and the current may carry object/debris that can impact against the panels. Thus, in addition to the support provided at the bottom of the vertical support member 118 by the angled plates 502, an angled support bar 1606 may be used to further support and stabilize the vertical support member against unexpected forces incident on the barrier system. The support bar 1606 is coupled between an upper bracket 1602 located at a point on the back wall 406 of the vertical support member that is about a distance 1608 equal to one third of the height of the panel 104 from the top of the panel (or ⅔rds from the bottom/ground surface). A support bracket 1604 is anchored to the ground surface at the lower end of the support bar 1606. The upper bracket can be attached by adhesive or other mounting means, or it can be integrally formed on the vertical support member 118. The angle of the support bar can be about forty five degrees in some embodiments. FIG. 17 shows a rear perspective view of a flood panel barrier system including a support brace, in accordance with some embodiments where the “T” shaped vertical support member 1002 is used. The only difference from the embodiment of FIG. 16 is that the upper bracket 1602 is attached to the back side of the front wall 1004 of the vertical support member 1002. The distance 1702 is equal to the distance 1602. FIG. 18 shows a front perspective view of a flood panel barrier system including a support brace, in accordance with some embodiments. In this case the upper bracket 1602 is attached to the front side of the panel 104, and the lower bracket 1604 is located in front of the barrier system, meaning it will be in the water if there is a flood event. Preferably the upper bracket 1602 will be opposing a similar bracket 1602 on the other side of the barrier, but that is not necessary for the front-mounted support bar to be effective.
The disclosed embodiments provide a flood panel barrier system and novel support structures that reduce the spacing necessary to deploy the flood panel barrier system. By using lightweight, rigid vertical support members that can be fixed in place using opposing angled plates that both anchor to the ground and interfere with movement of the vertical support member, the use of bracing arms is not necessary in most applications. The disclosed fastening units allow for rapid deployment of the disclosed flood panel barrier system because they do not require a wrench to tighten/loosen due to the provision of a puck-shaped knob on the tap bolt shank. Overall, these features provide a flood panel barrier system that is easier and faster to deploy and take down, and which requires less space than conventional barrier systems.
The claims appended hereto are meant to cover all modifications and changes within the scope and spirit of the present invention.
