FIELD OF THE INVENTION The present invention relates generally to the field of construction, and to temporary structures erected to access various parts of various structures. In one aspect, the present invention relates to the integration of a supported work platform system and a suspended work platform system, and a structural assembly for achieving the same.

Work platforms and other access structures, including suspended work platform systems and scaffolds, allow workers to access hard-to-reach workplaces, and can be assembled on-site as needed. For example, when working on a structure such as a bridge without a stable base or suitable for building a standard supported work platform, a suspended work platform allows workers to access the underside of the structure. The suspended work platform also eliminates the need to build standard work platforms and platform systems to impractical substantial heights. However, a suspended work platform is not always ideal for accessing some structures. Even after the suspended work platform is in place, it can be advantageous for a supported work platform to provide improved access to some structures. Accordingly, it may be advantageous to install a supported working platform on top of the suspended working platform.

Suspended work platforms use plywood panels secured within a framed structure to form a platform that is suspended from an overhead structure. Legs used with conventional supported work platforms apply large concentrated loads. The plywood panels used in the suspended work platform system cannot withstand the pressure exerted by the frame legs and the load must be properly distributed over the structural members using dunnage and/or beams. Installing a dunnage system or beam requires significant equipment, effort, and time. In addition, dunnage systems only withstand downward loads and require additional guy lines or bracings to withstand lateral, upward, or overturning forces. In other words, the dunnage system only prevents movement in one direction and requires a significant amount of extra equipment and materials to prevent movement or movement when the standard work platform system is installed on the suspended work platform system. Dungeons are virtually structurally incapable of integrating a standard supported work platform system with a suspended work platform system.

In summary, there exists a need in the art of working platforms and working platform support systems to overcome the deficiencies noted above and other deficiencies. There is a need for an improved system that effectively integrates suspended and supported work platforms and that properly distributes the force exerted by the supported work platform system on the structural members of the suspended work platform system.

While certain preferred embodiments of the present invention will be shown and described in detail, it should be understood that many changes and modifications may be made therein without departing from the scope of the appended claims. The scope of the present invention is not to be limited in any way by the number, material, shape, relative arrangement, etc. of the components, but is disclosed by way of example only. BRIEF DESCRIPTION OF THE DRAWINGS The features and advantages of the present invention are illustrated in detail in the accompanying drawings, wherein like reference numerals refer to like elements throughout.

As a prelude to the detailed description, as used in this specification and the appended claims, the singular forms "a", "an", "the" include the plural, unless the context clearly dictates otherwise. It should be noted that Moreover, as used herein, the term “overhead structure” refers to any physical structure to which a work platform may be suspended. Likewise, the term “structure” refers to any physical structure accessible using a suspended work platform system, whether or not the supported work platform system is integrated. In some implementations, the structure and overhead structure may be the same. Exemplary structures and overhead structures include, but are not limited to, bridges, marine rigs, boilers, boiler pendants, elevated and suspended structures, and ships.

Referring now to the drawings, FIG. 1 shows an exemplary unit 120 of a foundation structure 100 . In the example implementation shown, the unit 120, which is a unit of the first work platform system, has four hubs 150 such that the joists 140 are coplanar and secured to the hubs 150 at approximately right angles. Includes four joists 140 connected by. Hubs 150 and joists 140, along with an optional intermediate support deck joist 52, provide a framework for supporting platform 170. In the example implementation shown, the platform 170 is split into two platforms 170A, 170B with an intermediate support deck joist 52 providing structural support between the platforms 170A, 170B. In other example implementations, a single platform 170 may be used, or the platform 170 may be subdivided into two, three, or more platforms.

2 shows an exemplary foundation structure 100 including a plurality of units 120 connected together at hubs 150 . In the illustrated exemplary embodiment, the foundation structure 100 is a working platform system comprising a plurality of working platform units. In other exemplary implementations, the foundation structure 100 may be a single unit 120 . In still other exemplary embodiments, the foundation structure 100 has a single joist 140 or at least two coplanar joists 140 configured to have two coplanar portions spaced apart from each other and not linear with respect to each other. It can be any structure or system that provides a substantially flat surface.

The joist 140 is any elongate structural member configured to bear or support a load, such as a bar joist, truss, section (ie, I-beam, C-beam, etc.), or the like. Hub 150 is an interconnecting structure such as a node, hinge, pivot, post, column, center, shaft, spindle, or the like. Accordingly, one of ordinary skill in the art will appreciate that the size, shape, and arrangement of the hubs 150 and joists 140 may be varied to provide the work platform unit 120 and system 100 .

For example, the length of the joists 140 and the positions of the joists 140 and the hubs 150 may vary depending on the desired size and configuration of the base structure 100 . In the example implementations shown, the units 120 are rectangular, so that the joists 140 in one direction are longer than the joists 140 extending in the opposite direction, making the generally rectangular foundation structure 100 . However, the joists 140 may be of any length and may be connected with the hubs 150 at any angle allowed by the design of the hubs 150 . The size and shape of the support platforms 170A, 170B may likewise vary depending on the configuration of the joists 140 and hubs 150 .

In the example implementations shown in FIGS. 1 and 2 , the foundation structure 100 is shown as an access structure, such as a working platform system. Specifically, the foundation structure 100 is shown as a work platform system that is designed to be suspended from an overhead structure (ie, a suspended work platform system). However, the foundation structure 100 may be any foundation structure, as discussed above, including any type of access structure (ie, suspended work platform system, supported work platform system, scaffolding, retaining). . In preferred exemplary embodiments, the foundation structure 100 is any structure having at least one unit 120 with two coplanar parallel joists 140 . More preferably, the foundation structure 100 is a working platform system, even more preferably, a suspended working platform system. In the most preferred embodiment, the foundation structure 100 is an articulated suspended work platform system as described herein.

FIG. 3 depicts an exemplary hub 150 for use with the foundation structure 100 , which in the described example implementation is an articulated suspended work platform system. In the illustrated embodiment, hub 150 is configured to allow articulation of both hub 150 and joist 140 when attached to joist 140 . Articulation as used herein is defined as the ability to swing and/or rotate about a pivot point or axis. The hub 150 also allows the unit 120 and then the foundation structure 100 to be suspended from the overhead structure. However, in other exemplary embodiments, hub 150 may only provide articulation of hub 150 or joist 140 , or may not allow articulation. In still other example implementations, hub 150 may not allow for suspension of unit 120 or foundation structure 100 .

In the exemplary embodiment shown in FIG. 3 showing a hub 150 that allows for the articulation of both the hub 150 and the joist 140 as well as the suspension of the unit 120 and the foundation structure 100, the hub 150 ) comprises an upper element 11 and a lower element 12 spaced apart at the distal ends of the intermediate region 15 . The upper element 11 and the lower element 12 may be of a substantially flat configuration as well as parallel to each other. Upper element 11 and lower element 12 are octagonal in the illustrated embodiment. The intermediate zone 15 may be a cylindrical zone, wherein the longitudinal axis of the intermediate zone 15 is perpendicular to the planes of the upper element 11 and the lower element 12 . In the illustrated embodiment, the intermediate zone 15 is a column of columns. In the illustrated exemplary embodiment, to show that the middle section 15 is hollow, the lower portion of the middle section 15 has been removed for clarity.

A plurality of openings 13 , 14 extend through both the upper element 11 and the lower element 12 , respectively. A plurality of openings 13 (eg, 13A, 13B, 13C, 13D, 13E, 13F, 13G, 13H) are dotted on upper element 11 to provide various places for connection to one or more joists 140 . have. A plurality of openings 14 (eg, 14A, 14B, 14C, 14D, 14E, 14F, 14G, 14H) are likewise spaced apart on lower element 12 such that respective openings (eg, 13A and 14A) are coaxial have.

In the center of the upper element 11 is a central opening 16 configured to receive a suspension connector for securing the unit 120 and the foundation structure 100 to the overhead structure. The central opening 16 may be of a generally cruciform configuration as four slots 17 (eg, 17A, 17B, 17C, 17D) extend from its central opening region 19 . A series of cross slots 18A, 18B, 18C, 18D traverses and interconnects each of the four slots 17A, 17B, 17C, 17D. As shown in FIG. 4 , the slots 17 , 18 and the central opening area 19 interact with one end of the suspension connector 80 and secure it to the hub 150 . The other end of the suspension connector 80 is fixed to the overhead structure 90 to suspend the foundation structure 100 . One of ordinary skill in the art will readily appreciate that the slots 17 , 18 and central opening region 19 may have other configurations and designs as long as the suspension connector 80 can engage the hub 150 .

For increased strength, a second reinforcing plate 20 may be added to the underside of the upper element 11 , wherein the openings of the reinforcing plate 20 constitute a central opening 16 and all auxiliary openings 17 , 18 , 19) corresponds to A handle 22 is optionally added to the side of the intermediate section 15 .

5 is a top perspective view of an interconnection between a single hub 150 and a single joist 140 . The exemplary joist 140 shown in FIG. 5 includes an upper element 32 and a lower element 33 . A plurality of diagonal support members 38 are interspersed between the elements 32 , 33 . Each element 32 , 33 consists of two L-shaped angle member parts 39A, 39B called a joist chord. Elements 32 and 33 may typically have the same configuration, except that upper element 32 includes connecting holes 54A, 54B therebetween. The joist 140 includes a first end 31A and a second end 31B. An upper connecting flange 35 and a lower connecting flange 36 extend at both ends 31A, 31B of both the upper element 32 and the lower element 33 . The connecting holes 37 pass through both the upper and lower connecting flanges 35 , 36 . Accordingly, there are four upper connecting flanges 35A, 35B, 35C, 35D and four lower connecting flanges 36A, 36B, 36C, 36D. Therefore, the upper connecting flange 35A and the lower connecting flange 36A through which the connecting hole 37A passes are at the first end 31A extending from the upper element 32 . Likewise, there is an upper connecting flange 35B and a lower connecting flange 36B through which the connecting hole 37B passes, at the second end 31A of the upper element 32 . Subsequently, an upper connecting flange 35D and a lower connecting flange 36D extend from the first end 31A of the lower element 33 . A connecting hole 37D passes through these connecting flanges 35D, 36D. An upper connecting flange 35C and a lower connecting flange 36C through which the connecting hole 37C passes are at the second end 31B of the joist 30 extending from the lower element 33 .

Additional locking holes 360A, 360B, 360C, 360D, which are also located on the connecting flanges 35A, 35B, 35C, 35D, are inside the respective connecting holes 37A, 37B, 37C, 37D. A pin may be disposed through the connecting holes 37 and any two corresponding upper and lower openings 13 , 14 of the hub 150 . For example, the pin is through the upper connecting flange 35A; through opening 13A; via the lower connecting flange 36A (the whole of the first end 31A of the upper element 32); via the upper connecting flange 35D; through opening 14A; And then it may be disposed through the lower connection flange (36D). In this situation, the pin is further screwed through the connecting holes 37A, 37D. The pin includes two roll pins at its upper end, with the lower roll pin of the two roll pins serving as a stop to prevent the pin from sliding all the way through the joist 140 and hub 150 . The upper roll pin can serve as a finger catch to allow easy manipulation of the pin.

The design of these parts allows free rotation of both the joist 140 and the hub 150 while the joist 140 and the hub 150 are connected to each other. Rotation arrow R ₁ indicates rotation of joist 140 , while rotation arrow R ₂ indicates rotation of hub 150 . This rotational capability provides, in part, the articulation capability of the joists 140 and hubs 150 .

Those skilled in the art will appreciate that the joists 140 may have any length and be positioned at any angle that may be accommodated by the hub 150 . As in the case of a single unit 120 or the foundation structure 100 , when the hub 150 and the joists 140 are connected in plurality, the joists 140 are the units 120 and the foundation structure 100 accordingly. may be pivotable on the hubs 150 to form any configuration of Because of this articulation, the frame of the units 120 may be assembled in a collapsed form while the base structure 100 is in place, and then spread out from the base structure 100 . Once the desired configuration is achieved, the unit 120 is fixed to prevent further articulation.

An “in-the-air” assembly of additional units 120 is shown in FIGS. 6-10 . 6 shows an exemplary framework for unit 120A that is assembled and connected to an existing foundation structure 100 in unit 120B. The new unit 120A is in its initial position before articulation. The framework for unit 120A is final, as Figures 7-9 clearly indicated through motion arrow M by a combination or rotation of joists 140D, 140E, 140F and hubs 150D, 150E. It can be moved and rotated to the required position (FIG. 10). That is, the unit 120A is articulated in place.

Once in place, unit 120A can be locked in its final position using locking pins as described above. In other exemplary implementations, further articulation of the unit 120A may be prevented by securing the platform 170 (not shown) within the frame.

In alternative implementations, joist 140 and hub 150 may be secured to each other using other structures and methods well known in the art, and articulation of joist 140 and hub 150 relative to each other. Connections may not be allowed. For example, in some implementations, the joist 140 and hub 150 may be rigidly connected and locked in place to prevent articulation.

FIG. 11 is a top perspective view of the exemplary foundation structure 100 as shown in FIG. 2 , with access structure integration assemblies 300 secured to some joists 140 . As discussed in more detail below, the access structure integration assemblies 300 include at least one joist socket 60 and a channel structure 50 , wherein in the exemplary embodiment shown, they are intermediate support deck joists. It is secured to joists 140 running perpendicular to 52 . The access structure integration assemblies 300 are used to integrate the second structure 200 or the unit 220 or frame 210 of the second structure into the foundation structure 100 or unit 120 of the foundation structure. .

In one implementation, the second structure 200 can be any structure that can be incorporated using the access structure integration assemblies 300 , such as, for example, any access structure. Access structures include, for example, suspended work platform systems, supported work platform systems, scaffolds, and retaining systems.

As shown, joist sockets 60 are disposed on channel structures 50 running parallel to and secured to joists 140 . Therefore, the size of the base structure 100 and specifically the arrangement of the joists 140 depend on the configuration of the joist sockets 60 and consequently the configuration of the second structure 200 integrated with the base structure 100 . necessarily limited. In the exemplary embodiment shown, the channel structures 50 are secured to joists perpendicular to the intermediate support deck joists 52 . However, in other exemplary implementations, the channel structures 50 may be secured to joists parallel to the intermediate support deck joists 52 or both.

To save material and assembly time and cost, channel structures 50 are typically unidirectional, such as joists 140 running perpendicular to intermediate support deck joists 52 as shown in FIG. 11 . It is fixed to the joists 140 leading to. Therefore, the distance between the two joist sockets 60 on a given linear path of the joists 140 (such as joist sockets 60A, 60C, 60D) is variable, while the distance between them (such as joist sockets 60A, 60B) and same) the distance between joist sockets 60 on parallel joists remains the same. Typically, the length of the joists 140 extending perpendicular to the channel structures 50 corresponds to the desired length (or multiples or multiples thereof) of one dimension of the second structure 200 .

In some demonstrative implementations, the second structure 200 is a working platform system, and the length of the joists 140 extending perpendicular to the channel structures 50 dictates the bay size of the working platform system or the working platform system. corresponding to the length (or multiples or multiples thereof) of the frame member for In a preferred exemplary embodiment, the second structure 200 is a supported work platform system. The bay size of most supported work platform systems and hence the length of most frame members for supported work platform systems can be 3 feet, 42 inches, 4 feet, 5 feet, 7 feet, 8 feet, or 10 feet. have. Accordingly, the length of the joists 140 of the foundation structure 100 to be integrated with the second structure 200 which is a supported work platform system is preferably 3 feet, 42 inches, 4 feet, 5 feet, 7 feet, 8 feet. feet, or 10 feet.

12 shows an exemplary joist 140 with an access structure integrated assembly 300 including a single channel structure 50 and two joist sockets 60 . 13 shows the connection between the channel structure 50 and the joist socket 60 in more detail. As described in more detail below, the joist sockets 60 may be positioned and secured somewhere along the channel structures 50 .

In the exemplary embodiments shown, the channel structure 50 is a substantially square tubular shape having a rigid, flat bottom 51 and rigid, flat sidewalls 54 extending upwardly from the bottom 51 at approximately right angles. is the structure Each sidewall 54 terminates at a flange 53 , from which the flanges 53 extend towards each other but do not physically contact each other to form a linear gap along the length of the channel structure. It faces inward at approximately right angles, thereby forming a "C" shape. The inner and outer surfaces of the flanges 53 are substantially flat. In some implementations, the channel structure 50 is referred to as a C-shaped channel 50 .

In the example implementations shown, a C-shaped channel 50 is secured to a joist 140 with a deck retainer 58 between the joist 140 and the C-shaped channel 50 . Deck retainer 58 transmits and distributes force from second structure 200 incorporated into foundation structure 100 using integral assemblies 300 along joist 140 and specifically along joist cord 144 . It is a substantially linear rigid structure. When the joist socket 60 is used on an end joist, a toe board may be used in place of the deck retainer 58 .

In the exemplary embodiment shown in FIG. 12 , while a single C-shaped channel 50 is used, two deck retainers 58 are required to cover the length of the joist 140 . In other implementations, the deck retainers 58 , as long as the respective holes are aligned with the cage nuts 142 of the joists 140 so that the integral assemblies 300 can be secured to the joists 140 . and C-shaped channels 50 may have any length.

The joist socket 60 includes a tubular body 65 that is structurally integrated with a base 62 and support posts 67 as a single unit. The tubular body 65 is configured to receive the frame 210 from the second structure 200 to integrate the base structure 100 and the second structure 200 . In the described exemplary implementations, the frame 210 is cylindrical to correspond to the tubular body 65 of the joist socket 60 . However, it should be understood that the shape and size of the tubular body 65 may be varied to accommodate any shape of the framework 210 for the second structure 200 or unit 220 of the second structure.

T-bolts 70 together with nuts 78 secure joist socket 60 within C-shaped channel 50 while still allowing joist socket 60 to slide into C-shaped channel 50 . . As used herein, slidingly engaged means that two components (ie, joist socket and C-shaped channel) are secured to each other in a manner that allows sliding movement relative to each other. As shown in FIGS. 16 and 17 , the T-bolts 70 are formed such that the bolt head 72 slides in the C-shaped channel 50 and engages the inner surface of the flanges 53 . has a spherical shape. When the joist socket 60 is in the desired position on the C-shaped channel 50 , the nuts 78 are tightened to the T-bolts 70 to lock the joist socket 60 in place. When the nuts 78 are loosened, the T-bolts can slide freely within the linear gap of the C-shaped channels 50 , so that the joist sockets 60 are slidingly engaged with the C-shaped channels 50 . .

As shown, the holes 69 in the joist socket 60 are coupled with the holes in a supported work platform system component, such as a leg, to secure the supported work platform system to the suspended work platform system 100 . are sorted

In the exemplary embodiment shown, the joist socket base 62 has a width slightly greater than the width of the C-shaped channel 50 , and a length sufficient to support the single tubular body 65 . However, the joist socket base 62 may have any length to include one or more tubular bodies 65 , the diameter of which may be a leg, or supportive operation, to be coupled with the joist socket 60 . It will be appreciated that it depends on the dimensions of the other components of the platform system. Furthermore, the width of the joist socket base 62 may vary permissibly depending on the diameter of the tubular body 65 keeping in mind that the T-bolt 70 must still fully engage the base 62 .

A person skilled in the art will understand that when integrating the base structure 100 and the second structure 200 , the frame 210 , such as the legs of the second structure, will need to distribute the weight to the joists 140 . The strongest portions of the joists 140 are the panel points 144 (shown more clearly in FIGS. 14A and 14B ) where the diagonal support members 38 intersect. Traditionally, a dungeon, such as an I-beam or other support material, is placed on the joists 140 to transfer the load of the second structure to the panel points 144 . However, as discussed above, such dunnage systems prevent downward movement and provide little resistance to horizontal, vertical, and rotational movement. Accordingly, additional fastening devices (ie, tie downs, posts, branches, etc.) are used to more firmly support the second structure on the foundation structure.

By securing the deck retainer 58 and the channel structure 50 directly thereon in parallel with the joists 140 , the load of the supported work platform system is concentrated on the joist sockets 60 and the channel structures 50 . to the panel points 144 by Furthermore, because the joist sockets 60 completely surround the ends of the frame members for the supported working platform system, movement in all directions (including rotational movement) is prevented.

In the example implementations shown, the access structure integration assembly 300 secures the second structure 200 to prevent or limit movement beyond the downward direction. For example, in the exemplary implementation described, when joist socket 60 is secured within channel structure 50 , joist socket 60 is rotated in each axis for a total of six potential types of movement relative to joist 140 . In all directions along the x-axis, y-axis, and z-axis, including rotational movement, movement of the frame 210 fixed therein will be prevented. However, in other exemplary embodiments, the integration assembly 300 may limit or prevent movement in at least one of these directions, preferably in at least two directions, and more preferably in at least three directions. However, in the most preferred embodiment, the integral assembly 300 comprises all six of the frame members 210 (and thus the second structure 200) relative to the joist 140 (and thus the foundation structure 100). Limit or prevent tangible movement.

14A and 14B show exploded views of a joist 140 with an access structure integration assembly 300 . In the illustrated exemplary embodiment, the integration assembly 300 includes a joist socket 60 , and a channel structure 50 , which in the illustrated exemplary embodiment is a C-shaped channel. Although the square brackets representing the integral assembly 300 as shown in FIGS. 14A and 14B encompass the nuts 78 , the T-bolts 70 , and the deck retainer bolts 57 , these components are not disclosed herein. It is understood that they do not form the essential components of the integral assembly 300 as described in . Other fastening components and mechanisms may be used to secure the C-shaped channel 50 (and deck retainer 58 when used) to the joist 140 , and the joist sockets 60 include the T-bolt 70 . It may be slidably coupled to the C-shaped channels 50 using other structures and components.

The holes 56 (not shown) in the lower part 51 of the C-shaped channel 50 are aligned with the holes 59 in the deck retainer 58 (or toe board). The deck retainer bolts 57 are coupled with the cage nuts 142 installed in the joist 140 to fix the C-shaped channel 50 to the deck retainer 58 and the joist 140 .

T-bolts 70 may be inserted through holes 64 in base 62 of joist socket 60 to partially engage nuts 78 . With the T-bolts 70 loosely slidably engaged in the holes 64 , the joist socket 60 is C-shaped so that the head 72 of the T-bolts 70 is within the C-shaped channel 50 . It can slide on the end of the channel 50 . The head 72 of the T-bolts 70 is wider than the opening of the C-shaped channel 50 so that the T-bolt head 72 engages the inner surfaces of the flanges 53 . Thereby, upward movement of the joist socket 60 with respect to the C-shaped channel 50 is prevented. Once the joist socket 60 is in the desired position along the C-shaped channel 50 , the nuts 78 are tightened to the T-bolts 70 to hold the joist sockets 60 in place using compressive force. .

15 is an isometric view of a joist socket 60 showing a tubular body 65 having apertures 69 for engagement with structural elements of a supported work platform system. Base 62 includes holes 64 for receiving T-bolts 70 , and support posts 67 for structural integrity. In some example implementations, the base 62 may include additional holes 64 for the T-bolts 70 , and the posts 67 may have a different size or configuration.

16 is an end elevational view of the assembled integral assembly 300 . The tubular body 65 is hollow, with holes 69 open in the hollow tubular body 65 . T-bolts 70 extend through openings in base 62 and channel structure 50, which in the exemplary embodiment shown is a C-shaped channel. The bolt head 72 is wider than the opening of the C-shaped channel 50 , and thus engages the flanges 53 when tightened in place by a nut 78 . 17 is an exploded view of the integrated assembly 300 of FIG. 16 .

18 is a side view of the integral assembly 300 secured to the joist 140 . To secure the C-shaped channel 50 to the joist 140 , the deck retainer bolts 57 are routed through the joist 140 through the deck retainer 58 and the channel structure 50 , which in the exemplary embodiment shown is a C-shaped channel. ) in the cage nut 142 inside. 19 is an exploded view of integral assembly 300 with deck retainer 58 of FIG. 18 . 19 shows the aperture 59 of the deck retainer 58 having a projection around the bottom of the aperture 59 . As is more clearly shown in FIG. 18 , the protrusion around the aperture 59 fits between the two L-angle parts 39A, 39B of the elements 32 , 33 to provide additional stability.

FIG. 20 shows an exemplary second structure 200 integrated with the foundation structure 100 shown in FIG. 11 using access structure integration assemblies 300 . In the exemplary embodiment shown, the frame 210 of the second structure 200 includes interconnected legs secured within joist sockets 60 . Preferably and as shown in FIG. 20 , the second structure is a working platform system, such as a supported working platform system, comprising a plurality of individual units 220 .

In the illustrated exemplary embodiment, the foundation structure 100 includes a plurality of units 120 , and the framework 210 of the second structure includes a plurality of interconnected legs, and includes a plurality of individual units 220 . is configured to limit. In other exemplary implementations, the foundation structure 100 may be only a single unit 120 or two or more units 120 . In other example implementations, the second structure 200 may be a single unit 220 , or may be configured to include a frame 210 defining a single unit 220 . In other example implementations, the frame 210 of the second structure 200 may secure the platforms.

As the legs of the frame 210 are secured within the joist sockets 60 , the movement of the second structure 200 along the x-axis, y-axis, and z-axis relative to the joist sockets 60 and about each axis Rotational movement is prevented. When the joist sockets 60 are fixed on the C-shaped channels 50 (ie, screwed on the C-shaped channels to be non-movable), relative to the foundation structure 100 , the x-axis, the y-axis, Movement along the z-axis and rotational movement around the respective axis are prevented. Thus, the access structure integration assemblies 300 effectively integrate the base structure 100 and the second structure 200 . The term "integrated" as used herein with reference to a suspended working platform or platform system that supports a supported working platform or platform system includes a total of six types of movement of a supported working platform or platform system. (i.e., linear movement along the x-axis, y-axis, and z-axis, and rotational movement about the x-axis, y-axis, and z-axis) is prevented.

However, since the joist sockets 60 are movable along the C-shaped channels 50 when not secured in place, the second structure 200 is built in a convenient place on the foundation structure 100 and after assembly It can be slid to the final position. Likewise, the second structure may be built and slid at different locations on the foundation structure 100 to access the various structures at different points along the foundation structure 100 as needed.

Because the access structure integration assemblies 300 transfer the pressure exerted by the frame 210 of the second structure 200 to the panel points 144 , the size of the second structure 200 is a suspended work platform system. Limited by the amount of weight the joists 140 of 100 can support. For example, when the foundation structure 100 is a suspended work platform system and the second structure 200 is a supported work platform system, if the joists 140 continue to support the weight and pressure applied by the supported work platform system , the supported work platform system may comprise a single layer or multiple layers.

21 shows exemplary foundation structures 100 that are suspended work platform systems, into which second structures 200 that are supported work platform systems are incorporated. In the illustrated embodiment, the foundation structures 100 are suspended from the structure 90 which is a diagonal beam. As shown, to provide access to the underside of the structure 90 as well as the sides of the structure 90 between the suspended work platforms, the second structure 200 is constructed using the integrated system 300 to provide access to the foundation. integrated with the structure 100 .

21 also shows that the foundation structure 100 is integrated with the second structure 200 and can depend on the second structure 200 . For example, as shown in FIG. 21 , the foundation structure 100 may be an articulated suspension work platform system, and as described with reference to FIGS. 6 to 10 , the suspended work platform system 100b is It is built from the supported work platform system 200a, and the suspended work platform system 100c is built from the supported work platform system 200b. Thus, in order to continue accessing the structure 90 above the supported working platform 200c, workers assemble additional suspended working platforms, as described in FIGS. 6-10 , from the supported working platform 200c. After this, additional supported work platforms can be assembled that are integrated with the newly suspended platform system as described herein.

22 shows another example implementation of a foundation structure 100 integrated with a second structure 200 using access structure integration assemblies 300 . In the exemplary embodiment shown, the foundation structure 100 is a suspended work platform assembly and the second structure 200 is a supported work platform assembly. The foundation structure 100 is suspended from an overhead structure (not shown), eg used to access the substructures 91 .

As shown in FIG. 22 , the foundation structure 100 is suspended from the overhead structure, and the second structure 200 , which is a supported work platform system, is built upward from the foundation structure 100 . In the exemplary embodiment shown in FIG. 22 , a six storey supported working platform is secured above the foundation structure 100 . As shown in Figure 22, the layers of the supported work platform system are parallel to each other but not coplanar. As explained above, the number of layers of supporting structure 200 integrated with foundation structure 100 will depend on the work to be performed and the maximum amount of weight that the joists 140 can support.

23 shows an exemplary embodiment of a foundation structure 100 with access structure integration assemblies 300 incorporating a second structure 200 , wherein the foundation structure 100 is a suspended work platform system, wherein the 2 Structure 200 is a supported working structure system. The supported working platform system is built up from the suspended working platform system fixed below the structure 90 , which in the illustrated embodiment is a structure spanning two points, such as part of a bridge or offshore rig, for example. As shown, the foundation structure 100 is suspended below the structure 90 and also extends out of the footprint of the overhead structure 90 . The second structure 200 is built upward from a portion of the foundation structure 100 that is not directly below the structure 90 to access the sides of the structure 90 .

In other implementations, as shown in FIG. 24 , the second structure may be integrated with the base structure to provide support for an object, such as a tarpaulin or barrier. In FIG. 24 , the second structure 200 is integrated with the foundation structure 100 using integral assemblies 300 , and the second structure is used to secure the barrier 95 which is a tarpaulin. For example, when painting structure 90 , barrier 95 prevents debris (eg, soil, dust, water, pollen) from entering the work area and damaging or interfering with the painting or drying process. The barrier 95 also prevents contaminants (eg, smoke, vapors, particles) from escaping the work area and entering the environment. Therefore, the second structure 200 is used to create factory-like conditions in the field.

While the drawings and description provided herein illustrate a foundation structure 100 that is a suspended or articulated suspended work platform system that is integrated with a second structure that is a supported work platform system, the integrated assembly 300 may be configured to include various foundation structures and Of course, it can be used to incorporate second structures.
