The figures include additional features, dimensions and details that may not be described in detail in this written specification, but are nonetheless to be considered part of the disclosure. Of course, the invention is not to be limited to these configurations and embodiments and various other configurations and embodiments may fall within the scope of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0032] A first embodiment of the present invention will be described below with reference to FIGS. 1-8. Referring to FIG. 1, which is a perspective view of the first embodiment, an inflatable structure 10 includes plural inflatable, tubular structural supports 20 (in this case, arches 20), a separate, optional inflatable canopy 30, and plural anchors 40. The structural supports 20 are formed of inflatable, high-pressure air tubes, which are leak tight and arranged in a predesigned configuration in order to form the desired shape of the structure 10 so as to, in this case, cover the entire space to be protected and/or enclosed. Structural supports 20 are not to be limited to the arches shown in FIG. 1. While in this embodiment, the structural supports are shown as arches that span from one anchor 40 to another anchor (not shown) on the opposite side of the structure, the structural supports can be utilized as vertical columns or stacked, horizontal sidewall members, depending on the intended configuration. The manner of connecting adjacent structural supports 20 can be similar regardless of how they are utilized. Depending on the design, the structural supports 20 can be disposed adjacent one another and interconnected to form the canopy and/or sides of the structure, or the arches can be spaced apart with membranes or inflatable canopy sections or mattresses 30 attached to the structural supports 20 to form the canopy and/or sides of the structure. The structural supports 20 are preferably each anchored to a pair of anchors 40, which can be in the form of containers that can also house the equipment used to inflate the structural supports 20 and/or canopy sections 30 and store the structural supports and associated equipment during storage and transport, as will be explained later in more detail.

[0033] The structure 10, which can be inflated, deployed and retracted by inflation and deflation, respectively, includes numerous features in combination with the high-pressure inflated air tube structural supports 20, namely, an air-inflatable structural support connection system, structural support acoustic mitigation, structural supports monitoring system, multi-use anchors/containers, anti-deflation trussing or netting, ducted, reconfigurable air handling/HVAC, a structural and multi-functional deck, and unique loading doors. These features, while preferably used in combination, will be described individually below.

[0034] High pressure inflated air tube structural supports: The air beam technology allows the shell of the venue 10 to be formed extremely rapidly. Incorporating membrane materials, the air tube structural supports 20 are highly durable in multiple environmental conditions. This feature of durability and strength allows for large clear span spaces, without need of cross-bracing or other structural obstructions. These air tube structural supports 20 are uniquely structural and can support suspended loads. Unlike the present invention, many typical air supported structures are of a configuration where the entire building is under slightly higher pressure than ambient atmospheric pressure so that the fabric of the structure is pushed outwardly, including in an upward direction. This requires airlock doors and positive pressure HVAC systems. The high-pressure air tube feature of the present invention differs in that air tube structural supports 20 or ‘beams’ consisting of large fabric tubes under high-pressure comprise the supporting structure of the building. The tubes are formed of very strong high tensile fabric to resist the high pressures, typically either Hypalon or PVC with embedded high tensile fibers, such as Kevlar®, carbon fiber, or Dyneema® fibers that are arranged circumferentially around the tube. Dual membrane tubes can be provided to add an increased level of puncture mitigation. Tube diameters are calculated and engineered relative to the desired final facility size and loading requirements, plus mechanical, snow and wind loads required of all outdoor/touring infrastructures. Factors to be considered in designing the tubes include tube span, tube arc radius, tube diameter, tube loading, and tube pressure. The final dimensions and characteristics can be determined by those skilled in the art of structural engineering, particularly with regard to inflatable structures. The air tube structural supports 20 are also designed so as to retain the filled volume of air once inflated. Additional inflation is only necessary if air leaks or the volume changes due to temperature change or if more strength is required due to changing conditions.

[0035] Air tube structural support connection system: In order to create spaces of varying sizes as required by end use application or available real estate, individual air tube structural supports 20 can be connected or removed. Further this system allows for structures to be created in novel shapes and configurations. Air tube structural support connections can be achieved as follows.

[0036] The high-pressure air tube structural supports 20 can be “sistered” directly next to each other using traditional methods such as tent-lacing and standard rigging methods with weather covers to conceal the rigging and/or make the resulting canopy and/or sidewalls weathertight. This direct connection method is particularly suitable in configurations in which the structural supports are stacked horizontally to form sidewalls of the structure. The tubes can also be spaced at greater distances with typical tensile fabric membrane materials spanning the distance between the tubes. A combination of sistered tubes and membrane materials can be used to achieve the desired design. Alternatively, the structural supports 20 can be connected with inflatable canopy members or sections (mattresses) 30. Examples of this type of connection can be seen in FIGS. 1 to 8. In this case, referring to FIG. 2, adjacent structural supports 20 (20-1 to 20-3) are connected by inflatable canopy members 30 (30-1, 30-2). These inflatable canopy members 30 can be in the form of integrally connected tubes, individual tubes connected together, or a combination thereof.

[0037] FIG. 3 shows an example of an inflatable canopy section 30 having multiple, integral tubes. Each canopy section 30 is connected at its ends to adjacent structural members or arches 20 (20-1, 20-2) by any suitable connecting device, an example of which will be described later. Each canopy section 30 includes tubular canopy tubes 32, 34, which can be of different sizes. In the shown example, canopy tubes 32 are of a larger diameter (e.g., 20 inches) than that of canopy tubes 34, (e.g., 12 inches), which are provided alternately. The canopy tubes 32, 34 can be simply fused together in a parallel fashion, or more robustly connected as shown in FIGS. 6 and 7. In this example, each canopy tube 32, 34 is formed of a lower tubular section 32a, 34a and an upper tubular section 32b, 34b, with the upper and lower tubular sections being fused together at a connecting region 33, such as by a heat seal. This design also allows integration of noise attenuation materials, which will be discussed in further detail below.

[0038] Referring once more to FIGS. 3 and 4, the end of each canopy section 30 is provided with a releasable connector section 38 that allows releasable connection with an adjacent canopy section positioned between the same two adjacent structural tubes 20, that is, connection end-to-end in a longitudinal direction of the structural tubes. This connector section 38 can be in the form of hook and loop connection flaps, such as Velcro™ flaps. In addition, each canopy section is provided with connection features for connection to the structural tubes 20 as well as adjacent canopy sections in a direction transverse to the longitudinal direction of the structural tubes. This can be in the form of polymer flaps 39a with Velcro™ connections disposed along the ends contacting the air beams. Referring to FIG. 3, each flap 39a can be wrapped around an adjacent air tube structural support 20 and then secured with the Velcro™ connection. To facilitate this connection, the periphery of each air tube structural support 20 is provided with mating Velcro™ material. This mating Velcro™ material can be either directly connected to the air tube structural support periphery or each air tube structural support 20 can be wrapped with a sock having a Velcro™ exterior. A D-ring can be fixed to the flap 39a or a separate flap to allow connection with a ratchet strap, which allows adjacent canopy sections 30 to be connected to the same structural tube 20 and be tightly ratcheted toward one another for a sturdy connection to one another and the intervening structural tube. Note FIG. 5.

[0039] Each mattress section is provided with an air inlet 30a for inflation. Although the mattress tubes can be formed individually, each with an air inlet and each being filled separately, preferably the mattress tubes are pneumatically interconnected such that they can be inflated through a single air inlet 30a or a limited number of air inlets less than the number of canopy section tubes. Referring to FIG. 8, for example, although adjacent canopy section tubes 32, 34 are heat welded together to form the unitary canopy section, the pneumatic interconnection is provided by omitting welding at certain regions along the lengths of adjacent tubes so as to provide an air passages 30b between tubes. So as to allow for rapid deflation when deconstructing the structure, each canopy section tube is provided with one or more dump valves 30c.

[0040] Each air mattress can be provided with additional structural, architectural, or ornamental features. For example, referring to FIGS. 2 to 4, an extension 34c is provided at one end of every predetermined number of canopy section tubes 32, 34. In the shown embodiment, every sixth smaller diameter canopy section tube 34 is provided with the extension 34c. Mesh panels 37 can be attached between these extensions 34c to provide shade or the like or simply provide an architectural feature. Mesh panels 37 can be attached to the extensions 34c by Velcro™ strips 34d, for example. See FIG. 4.

[0041] Acoustic mitigation in tube structural supports and canopy sections: Optionally built into the air tube arches is noise mitigation technology, which significantly increases acoustic isolation from the surrounding environment. This is accomplished via acoustic nanofoam technology that can both be integrated within the tubes and/or hung as a liner from beneath the tubes or married to a separate membrane. This nanofoam can act both as an acoustic mitigator as well as a layer of insulation offering valuable R Value and HVAC advantages. As to the air tube structural supports 20, the nanofoam 22 can be filled throughout the length of the tubular member, as shown in FIG. 5. Alternatively, the nanofoam or other acoustic mitigating material can be provided in an interior sock disposed within the air tube structural member 20. The interior sock can be prefilled before insertion in the air tube structural member 20, or can be inserted and then be filled with the nanofoam or other acoustic mitigating material.

[0042] As to the canopy members, similarly, the nanofoam can be directly filled within the canopy tubes or provided in an interior sock. The structure of the canopy member 30 formed with an interior sock will be discussed herein. Referring to FIGS. 6 and 7, the interior socks in each canopy tube 32, 34 is integrated with the connector 33 between adjacent tubes. As shown in FIG. 7, an interior sock 36 is disposed in each canopy tube 32, 34 and runs along the length of the canopy tube. Each interior sock 36 is formed of a hollow polymer jacket 36a, which can be inflated or filled with a material, such as a nanofoam. In the shown example, each interior sock 36 is filled with a nanofoam or aerogel 36b. Adjacent socks are connected by a sock connector 35a that, for example, is fused to the outer surface of jacket 36a of the sock and runs along the connecting region 33 of the canopy tubes 32, 34. Sock connector 35a can be formed of a strip of polypropylene, for example, and be heat sealed to the exterior of the sock jackets 36a or connected by grommets or ties 35b, for example, to the sock jackets 36a. In this manner, the tubular canopy tubes 32, 34 are connected in a parallel fashion with a strong connection through their centers with sound attenuating materials integrated therein.

[0043] Air tube structural supports monitoring system: The system can monitor air tube pressure when inflated and automatically add air as needed to maintain optimal inflation. The inflation monitoring system is redundant and autonomous in monitoring and maintaining constant pressure within a fixed pressure point range. A range of operating pressures is required, as normal day/night changes in atmospheric pressure/temperature will affect daily pressure readings. This can be accomplished through a control system 100 shown schematically in FIG. 14. Control system 100 includes a controller 110 comprised of an MPU 112, a ROM 114, and a RAM 116, and further includes pressure sensors 50, environment sensors 60, air pumps 42, forecast module 700, and a communication module 80. ROM 114 stores programs for the monitoring system and RAM 116 provides a work area for processing by MPU 112. Pressure sensors 50 can measure the pressure in the air tubes and feedback that information to the controller 110. If the read pressure is outside of an allowable range, controller 110 activates the air pumps to inflate or deflate the structural tubes 20. The sensors can be provided in each tube supplied by a particular air pump. In addition, pressure sensors can also be provided in the canopy sections (mattresses). As the air mattresses are intended to form the canopy, they are not as critical for structural support and need not be interconnected with the monitoring system. The forecast module 70 of the control system can interface with an external weather monitoring system to receive external forecast information, such as a weather forecast. The control system 110 can control the pressure in the structural tubes 20 based on the forecast via a program stored in the ROM 114. For example, if high winds are predicted, the control system 100 can inflate the tubes above a normal range to provide increased rigidity.

[0044] The communication module 80 is also controlled by controller 110. For example, in the event of a reduction in pressure, the control system 100 automatically advises a registered operator via SMS/email through communication module 80 that it has initiated an inflate sequence, the frequency at which it was required (leak detection and alarm), and the amount of air required. The same applies for an over-pressure situation. Further, the forecast of adverse weather conditions can be communicated to the registered operator.

[0045] The system is provided with fully redundant inflation and monitoring options, as well as an air exchange temperature option to maintain internal temperatures of the tubes.

[0046] Not to replace an internal HVAC system, but rather to augment its effectiveness, an air dryer and management system can be integrated to assure air quality, that is, the supplied air is absent of moisture. Redundant power generators provide seamless back-up in the event of failure of the primary supply device.

[0047] Adaptive use containers: Referring to FIGS. 1 and 2, the air tube structural supports 20 are deployed via high-output air pumps or blowers 42 (not shown in FIGS. 1 and 2) directly from their shipping and storage containers, which also function as anchors 40, without having to source and connect inflation devices locally. The containers/anchors 40 can be easily accessible during operations for maintenance and local control of the air systems. The containers/anchors 40 preferably have an openable top and the structural supports 20 are structurally fastened to a rigging frame within the open top containers. Air supply pressure is provided to each tube either directly or via a distribution manifold. The fabric structural supports 20 exit the top of an open top container 40 and are unrolled toward a mating container, entering via the top. Air systems in both sides at both ends of every other (or each) tube are all configurable options. The containers can also serve as ballast for the structure. Space in the containers that is not dedicated to the tubes and the inflation equipment can be used to store the ballast, which can include water tanks, concrete construction blocks, or other locally sourced counter-weight options. This ballasting allows the structure to durably withstand adverse weather conditions. If water tanks are used as the ballast, they can be filled to the desired weight, depending on the size of the final structure and anticipated weather conditions. Finally, containers/anchors 40 also serve as a secondary acoustic baffle, isolating the inflated structure from surrounding environment.

[0048] Anti-Inflation Trussing or Netting: Referring to FIG. 2, within the main inflatable arch structure are a limited number of trussing members 45. These trussing members act as a secondary support mechanism and can be formed of metal or any suitable material having sufficient strength to support the weight of the structure at an elevation above the ground level in the event of minor or complete deflation. Although the primary inflation system is preferably fully redundant, should a catastrophic failure of multiple structural supports 20 occur, the air tube material will be caught and supported by the trussing. Therefore, the deflated tubes cannot fall onto equipment or personnel within the space. Further, the trusses function as structural members from which other equipment can be rigged, such as lighting and sound equipment. The trusses 45 and structural tubes 20 are preferably not structurally interconnected. Otherwise, if there were some interconnection, weather or wind loads causing movement of the tubes 20 might also cause movement of the trusses 45. Separate trussing 45 beneath the tube structure can also provide a fixed structure to rig from in addition to a level of redundancy in the event of catastrophic tube deflation. Alternatively, rather than rigid trusses 45, netting can be provided to catch and support the structure in the event of minor to complete deflation. The netting is preferably made of and supported by material strong enough to support the collapsed structural members. In one embodiment, the netting can be supported by the containers/anchors 40.

[0049] Ducted, reconfigurable air handling/HVAC: In order to suit internal configurations as determined by end users, air handling ducting can be repositioned and reconfigured for optimal heating and cooling needs by area. The air ducts are typically made from soft, breathable fabric which prevents condensation and mold. The air ducts preferably include an internal spiral spring and are preferably pre-fastened to the tubing structure prior to the air tube structural supports 20 being inflated. The air ducts are tubes themselves fabricated to suit the form of the air tube structure, and provide air handling to the zones and areas required. The ducting is light, easy to move, takes relatively small space in shipping, is physically cut/shaped to the venue itself, and is aesthetically pleasing. The flexible ducting can match the flexibility of the roof so that the two systems (roof and ducting) can move and deflect together.

[0050] Integrated utility distribution network: As end users may have varying needs in terms of power, IT, and plumbing, the venue incorporates a robust network of utility distribution pathways, including weather-tight penetrations for running utilities into the venue from the site. Cable/wiring access can be provided at multiple locations suited to the end user. External services can be delivered into the inside of the venue in an integrated and hermetic fashion. Rather than simply laying cables and services under the wall and into the space, which would create an entrance for weather, water and vermin, the integrated distribution network can deliver services from outside to inside in appropriate places suited to the pass-through needs of the actual services. This can include simple wiring and the HVAC ducting discussed above, all of which requires integration into the fabric of the venue itself and structural support. Mechanical systems that can be integrated with venue's air tube structural supports 20 include flexible electrical ducting, the flexible HVAC ducting discussed above, and fire sprinkler systems using flexible PEX tubing. These systems can have universal attachment points that are integrated onto the fabric surface of the air tube structural supports 20. The electrical conduits can terminate at ‘soft’ electrical boxes for either interior venue lighting or air tube lighting that illuminates the surface of the fabric tubes for exterior lighting effects.

[0051] Structural and multi-functional deck: Referring to FIG. 9, the decking 120 of the venue forms its floor and features robust point and axle load tolerance in loading areas suited to truck traffic, and 50 lb/sq ft load tolerance in other areas so as to allow users to configure the open space as desired. Further, the decking creates a crawl space area that allows for rain water mitigation and drainage. The decking system is designed to suit the desired shape of the structure (for example, round or rectangular). The decking can use conventional components normally found in the scaffolding industry, for which world-wide supply chains exist for parts, service, and support. This provides a large level of flexibility for out-of-level surfaces where the structure 10 might be installed—parking lots, dry river beds, or downtown areas. The deck 120 can be provided with inflatable seating 125 as shown in FIGS. 9 and 10. For example, the seating can include foundational tubes 126 as well as other inflatable sections 127 forming the seating, backrest, and legs of the seats. The foundational tubes 126 can be provided with separate chambers and active air supplies for deflation prevention. The surfaces of the seating can be made of, for example, ballistic nylon for wear and puncture protection.

[0052] Loading doors: Incorporating alternate iterations of the air beam technology, the venue incorporates a loading-sized automatic door for internal equipment installation and load out. Analysis of the user's operational needs is completed during the design phase. This includes identifying the number of end user requirements for interior access, such as catering vehicles, daily deliveries, fork lift access, or transport trucks. All can be accommodated by creating access portals through the perimeter container systems.

[0053] High-Speed Systems: All structures, tools, materials, etc., of which the venue is comprised, are specifically designed for exceptional speed of deployment and take down.

[0054] While the first embodiment of the present invention described above utilizes multiple arches as the air tube structural members 20, the present invention is not to be limited to this configuration. Other configurations are shown in FIGS. 11 to 13. In the embodiment of FIG. 11, structure 200 is formed of multiple vertical columns formed by air tube structural members 220. In the shown embodiment, adjacent air tube structural members 220 are directly connected using standard lacing techniques. Optionally, web material or air mattresses can be disposed between these structural members 220 and interconnected similarly to the manner described with respect to the first embodiment. In the embodiments of FIGS. 12 and 13, structures 300, 400 are formed of multiple horizontal air tube structural members 320, 420, which are interconnected in any of the manners described with respect to the previous embodiments. The canopies in these configurations can be inflatable members or a membrane structure.

Assembly and Disassembly

[0055] Erection of the structure 10 having the foregoing features will now be described. The structure 10 can be delivered to a site with almost all of the structural components stored in a number of transportable containers/anchors 40. As an example, the containers 40 can be individually transported on the trailers of semi-trucks. The containers are arranged in their final, predetermined locations as per the predesigned configuration. Container placement is done via forklift, side loader, or flat-bed tow truck. The equipment required for container and material handling is readily available. A crane would not typically be required.

[0056] After the containers/anchors 40 are properly positioned, the fabric forming air tube structural supports 20 is unrolled from the containers and connected to opposite containers/anchors. If additional ballast is required, it is added to the containers as needed and then air tube structural supports 20 are inflated. The air tube monitoring system can be programmed and initiated. Preferably, but not necessarily, before inflation, the anti-deflation trussing or netting 45 is erected. The unrolled tube fabric can be guided over the trussing and connected to the complementary containers/anchor prior to inflation. If tubes are to be sistered, that can be done before or after inflation, depending on the design. If membrane materials or mattresses 30 are used, they are preferably attached to the structural supports 20 after inflation using the connecting devices described earlier. Likewise, the multi-functional deck and loading doors can be installed preferably before, but also after, the structure is inflated. The completed structure advantageously lacks any structural cross members or bracing supports within the clear span of the venue, yet maintains integration of HVAC ducting and utilities conduits. When no longer needed, the structure is disassembled in the opposite order of construction, with all of the components stored in the containers for subsequent transportation to the next site or storage area.

[0057] Although this invention has been described in certain specific exemplary embodiments, many additional modifications and variations would be apparent to those skilled in the art in light of this disclosure. It is, therefore, to be understood that this invention may be practiced otherwise than as specifically described. Thus, the exemplary embodiments of the invention should be considered in all respects to be illustrative and not restrictive, and the scope of the invention to be determined by any claims supportable by this application and the equivalents thereof, rather than by the foregoing description.
