  The present invention relates generally to the field of construction and temporary structures assembled 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 accomplishing this.

  Work platforms and other access structures, including suspended work platform systems and scaffolds, allow workers to access work areas that are difficult to reach and can be assembled at work places as needed . For example, when working on structures such as bridges that do not have a stable and suitable bottom for assembling standard supported work platforms, suspended work platforms allow workers access to the underside of these structures. It becomes possible to do. Suspended work platforms also eliminate the need to assemble standard work platforms and platform systems to a fairly cumbersome height. However, suspended work platforms are not always ideal for access to some structures. A supported work platform may be beneficial to provide improved access to some structures even after the suspended work platform is in place. Accordingly, it may be beneficial to install a support work platform over a suspended work platform.

  Suspended work platforms use plywood panels that are secured in a frame-like structure to create a platform that is suspended from an overhead structure. Legs used in conventional supported work platforms provide a large concentrated load. The plywood used in the suspended work platform system cannot withstand the pressure exerted by the frame legs, and the load is properly distributed to the structural members using dunnage and / or beams. There must be. Introducing a dunnage system or beam requires considerable equipment, labor and time. In addition, the dunnage system can only withstand downward loads and requires additional support wires or pressers to withstand lateral, upward, or overturning forces. In other words, the dunnage system only prevents unidirectional movement, and a significant amount to prevent the standard work platform system from moving or shifting when installed in a suspended work platform system. Extra equipment and materials are needed. Dunnage material cannot accurately integrate a standard supported work platform system with a suspended work platform system.

  In summary, there is a need in the art of work platforms and work platform support systems to overcome the above and other shortcomings. There is a need for an improved system that securely integrates a suspended and supported work platform and that properly distributes the forces applied to the structural members of the suspended work platform system by the supported work platform system.

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 used in the specification and the appended claims as a prelude to the detailed description, the singular forms “a”, “an”, and “the” specifically refer to contexts It should be noted that references to the plural are included unless otherwise stated. Further, as used herein, the term “overhead structure” refers to any physical structure from which a work platform can be suspended. Similarly, the term “structure” refers to any physical structure that is accessible using a suspended work platform system, with or without an integrated supported work platform system. In some embodiments, the structure and the overhead structure may be the same. Exemplary structures and overhead structures include, but are not limited to, bridges, offshore drilling rigs, boilers, boiler accessories, elevated and suspended structures, and ships.

  Referring now to the drawings, FIG. 1 shows an exemplary unit 120 of substructure 100. In the exemplary embodiment shown, unit 120 is a unit of the first working platform system, but includes four joists 140 coupled by four hubs 150, which are coplanar and substantially perpendicular. It is fixed by the hub 150. Hub 150 and joist 140, together with optional intermediate support deck joist 52, provide a framework for supporting platform 170. In the exemplary embodiment shown, platform 170 is divided into two platforms 170A and 170B, with intermediate support deck joist 52 providing structural support between platforms 170A and 170B. In further exemplary embodiments, a single platform 170 may be used, or the platform 170 may be subdivided into two, three or more platforms.

  FIG. 2 illustrates an exemplary substructure 100 that includes a plurality of units 120 coupled by a hub 150. In the exemplary embodiment shown, substructure 100 is a work platform system that includes a plurality of work platform units. In a further exemplary embodiment, the substructure 100 can be a single unit 120. In a still further exemplary embodiment, the substructure 100 has at least two coplanar joists 140 or one configured to have two coplanar portions that are not linear with each other and separated by a distance. It can be any structure or system that provides a substantially flat surface with a joist 140.

  The joist 140 is any elongated structural member suitable for supporting or supporting a load, such as a bar joist, truss, shaped steel (ie, I-beam, C-beam, etc.) or the like. The hub 150 is an interconnect structure such as a knot, hinge, pivot, column, post, center, shaft, shaft or the like. Accordingly, those skilled in the art will recognize that the size, shape and configuration of the hub 150 and the joist 140 may vary to provide the working platform unit 120 and the system 100.

  For example, the length of the joist 140 and the position of the joist 140 and the hub 150 can vary depending on the desired size and configuration of the substructure 100. The exemplary embodiment shown, the unit 120 is rectangular and forms a generally rectangular substructure 100 with a joist 140 that is longer in one direction than a joist 140 extending in the opposite direction, while the joist 140 Can be any length and can be coupled to the hub 150 at any angle allowed by the design of the hub 150. Similarly, the size and shape of the support platforms 170A, 170B may vary depending on the configuration of the joist 140 and the hub 150.

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

  FIG. 3 shows an exemplary hub 150 for use with substructure 100, which in the exemplary embodiment described is an articulating suspended work platform system. In the exemplary embodiment shown, the hub 150 is configured to allow articulation of both the hub 150 and the joist 140 when coupled to the joist 140. Articulation, as used herein, is defined as the ability to pivot and / or rotate about a pivot point or pivot. The hub 150 also allows the unit 120 and then the substructure 100 to be suspended from the overhead structure. However, in further exemplary embodiments, the hub 150 may provide articulation of only the hub 150 or the joist 140 or does not allow articulation. In still further exemplary embodiments, the hub 150 may not allow the unit 120 or the substructure 100 to be suspended.

  In the exemplary embodiment shown in FIG. 3, this shows a hub 150 that allows articulation of both hub 150 and joist 140 as well as suspension of unit 120 and substructure 100, which includes top surface element 11, And a bottom element 12 spaced at the distal end of the intermediate portion 15. The top element 11 and the bottom element 12 can be in a substantially flat configuration and can be parallel to each other. Top element 11 and bottom element 12 are octagonal in the embodiment shown. The intermediate part 15 can be a cylindrical part, the longitudinal axis of the intermediate part 15 being perpendicular to the planes of the top element 11 and the bottom element 12. In the embodiment shown, the intermediate portion 15 is a right circular cylinder. In the exemplary embodiment shown, the lower portion of the intermediate portion 15 has been removed for clarity, indicating that the intermediate portion 15 is hollow.

  A plurality of holes 13, 14 extend through both the top element 11 and the bottom element 12, respectively. A plurality of holes 13 (eg, 13A, 13B, 13C, 13D, 13E, 13F, 13G, 13H) are interspersed on the top surface element 11, thereby providing various locations for connection with one or more joists 140. To do. The plurality of holes 14 (eg, 14A, 14B, 14C, 14D, 14E, 14F, 14G, 14H) are similarly spaced on the bottom element 12 such that each hole (eg, 13A and 14A) is coaxial. .

  There is a central opening 16 in the center of the top element 11, which is configured to receive a suspension connector for securing the unit 120 and substructure 100 to the overhead structure. The central opening 16 may be generally cruciform because its central opening region 19 has four slots 17 (eg, 17A, 17B, 17C, 17D) extending therefrom. It is a series of intersecting slots 18A, 18B, 18C, 18D that traverse and intersect each of the four slots 17A, 17B, 17C, 17D. The slots 17, 18 and the central opening region 19 interact with one end of the suspended connector 80 to secure it to the hub 150 as shown in FIG. The other end of the suspension connector 80 is fixed to the overhead structure 90 to suspend the substructure 100. Those skilled in the art will readily recognize that the slots 17, 18 and the central opening region 19 may have other configurations and designs as long as the suspended connector 80 can engage the hub 150.

  A second reinforcing plate 20 can be added to the underside of the top element 11 for additional strength, where the opening of the reinforcing plate 20 has a central opening 16 configuration and its associated openings (17, 18, 19). Matches all of A grip 22 is optionally added to the side of the intermediate portion 15.

  FIG. 5 shows a top perspective view of the interconnection of one hub 150 and one joist 140. The example joist 140 shown in FIG. 5 includes an upper element 32 and a lower element 33. Dispersed between the elements 32, 33 are a plurality of diagonal support members 38. Each element 32, 33 is made from two L-shaped angle steel pieces 39A, 39B called joist cords. Elements 32 and 33 may typically be identical in construction, except that upper element 32 includes a connector hole 54A, 54B in the center of its span. The joist 140 includes a first end 31A and a second end 31B. An upper connection flange 35 and a lower connection flange 36 extend at both end portions 31A and 31B of both the upper element 32 and the lower element 33. A connection hole 37 penetrates both the upper and lower connection flanges 35 and 36. Therefore, there are four upper connection flanges 35A, 35B, 35C, 35D and four lower connection flanges 36A, 36B, 36C, 36D. Therefore, it is the upper connection flange 35A and the lower connection flange 36A that extend from the upper element 32 at the first end 31A, and the connection hole 37A passes through them. Similarly, the upper connection flange 35B and the lower connection flange 36B extend at the second end 31A of the upper element 32, and the connection hole 37B passes through them. Continuing, it is the upper connection flange 35D and the lower connection flange 36D that extend to the first end 31A of the lower element 33. A connection hole 37D passes through the connection flanges 35D and 36D. Extending from the lower element 33 at the second end 31B of the joist 30 is an upper connection flange 35C and a lower connection flange 36C through which a connection hole 37C passes.

  Inside each of the connector holes 37A, 37B, 37C, 37D are additional locking holes 360A, 360B, 360C, 360D that are also arranged in the connection flanges 35A, 35B, 35C, 35D. Pins can be placed through the connection holes 37 and any two matching top and bottom holes 13, 14 of the hub 150. For example, the pin may be routed through the upper connection flange 35A, through the hole 13A, through the lower connection flange 36A (all of the first end 31A of the upper element 32), through the upper connection flange 35D, through the hole 14A, and subsequently the lower side. It can be arranged through the connecting flange 36D. In this situation, the pin further passes through the connection holes 37A, 37D. The pin may include two rotating pins at its upper end, and the lower part of the two rotating pins serves as a stopper, thereby preventing the pins from slipping through the joist 140 and the hub 150. The upper rotating pin can serve as a finger knob that allows simple manipulation of the pin.

  The design of these parts is such that free rotation of both the joist 140 and the hub 150 is allowed even while the joist 140 and the hub 150 are connected. The rotation arrow R1 indicates the rotation of the joist 140 and R2 indicates the rotation of the hub 150. These rotational capabilities provide, in part, the ability to move the joist 140 and the hub 150.

  As will be appreciated by those skilled in the art, the joist 140 can be of any length and can be positioned at any angle that can be received by the hub 150. When a plurality of hubs 150 and joists 140 are combined, such as in the case of a single unit 120 or substructure 100, the joists 140 are on the hub 150 to produce the unit 120 and thus any shape of the substructure 100. Can pivot. By this joint movement, the frame of the unit 120 can be assembled in a folded form while the foundation structure 100 is in a predetermined position, and then expanded outward from the foundation structure 100. Once in the desired shape, the unit 120 is fixed to prevent further articulation.

  This “in-air” assembly of this further unit 120 is shown in FIGS. FIG. 6 shows an exemplary framework of unit 120A assembled and coupled to existing substructure 100 with unit 120B. The new unit 120A is in its initial position and before the joint movement. As clearly shown in FIGS. 7-9 by the movement arrow “M”, the combination or rotation of the joists 140D, 140E and 140F and the hubs 150D and 150E causes the frame of the unit 120A to move to its final required position (FIG. 10) can be moved and rotated. That is, the unit 120A moves in a joint position and fits in a predetermined position.

  Once in place, unit 120A can be locked in its final position using a locking pin as described above. In a further exemplary embodiment, further articulation of unit 120A can be prevented by securing platform 170 (not shown) within the framework.

  In alternative embodiments, the joist 140 and the hub 150 may be secured together using other configurations and methods known in the art and may not allow the joist 140 and the hub 150 to articulate relative to each other. For example, in some embodiments, the joist 140 and the hub 150 can be securely coupled and locked into place to prevent articulation.

  FIG. 11 is a top perspective view of an exemplary substructure 100 as shown in FIG. 2, wherein an access structure integrated assembly 300 is secured to several joists 140. As discussed in more detail below, the access structure integrated assembly 300 includes at least one joist socket 60 and a grooved structure 50, which in the illustrated exemplary embodiment, includes an intermediate support deck joist 52. Are fixed to a joist 140 extending perpendicularly to each other. The access structure integration assembly 300 is used to integrate the second structure 200 or the second structure unit 220 or framework 210 into the substructure 100 or into the substructure unit 120. The

  In one embodiment, the second structure 200 can be any structure that can be integrated using the access structure integration assembly 300, such as, for example, any access structure. Access structures include, for example, a suspended work platform system, a support work platform system, a scaffold, and a support.

  As shown, the joist socket 60 is disposed in a grooved structure 50 that extends parallel to and secured to the joist 140. The dimensions of the substructure 100, and in particular the configuration of the joist 140, thus inevitably limit the configuration of the joist socket 60 and ultimately the configuration of the second structure 200 integrated with the substructure 100. In the exemplary embodiment shown, the grooved structure 50 is secured to a joist perpendicular to the intermediate support deck joist 52. However, in a further exemplary embodiment, the grooved structure 50 may be secured to a joist parallel to the intermediate support deck joist 52 or to both.

  To save material and assembly time and costs, the grooved structure 50 typically extends unidirectionally, such as that extending perpendicular to the intermediate support deck joist 52 as shown in FIG. Fixed to the joist 140. The distance between two joist sockets 60 on a given linear path of joist 140 (such as joist sockets 60A, 60C, and 60D) can therefore be varied, while one (such as joist sockets 60A and 60B) is a parallel joist. The distance between the upper joist sockets 60 remains the same. Typically, the length of the joist 140 extending perpendicular to the grooved structure 50 is equal to (or is a factor or multiple of) the one-dimensional desired length of the second structure 200.

  In some exemplary embodiments, the second structure 200 is a work platform system, and the length of the joist 140 extending perpendicular to the grooved structure 50 is the size of the work platform system. Or equal to the length of the framework member of the working platform system (or a factor or multiple thereof). In a preferred exemplary embodiment, the second structure 200 is a supported work platform system. The frontage size of most supported work platform systems, and hence the length of most framework members of supported work platform systems, is 3 feet, 42 inches, 4 feet, 5 feet, 7 feet, 8 feet or 10 feet. possible. The joist 140 of the substructure 100 integrated with the second structure 200, which is a supported work platform system, is therefore preferably 3 feet, 42 inches, 4 feet, 5 feet, 7 feet, 8 feet in length or Can be 10 feet.

  FIG. 12 shows an exemplary joist 140 having an access structure integrated assembly 300 that includes one grooved structure 50 and two joist sockets 60. FIG. 13 shows the joint between the grooved structure 50 and the joist socket 60 in more detail. The joist socket 60 may be disposed and secured anywhere along the grooved structure 50 as described more fully below.

  In the exemplary embodiment shown, the fluted structure 50 is a substantially rectangular tubular structure having an integral flat bottom portion 51 and extending upwardly from the bottom portion 51 at a substantially right angle. It has an integral flat side wall 54 that extends. Each side wall 54 terminates in a flange 53 that is substantially perpendicular to the inside from the side wall 54, so that the flanges 53 extend towards each other but do not physically contact each other and are linear gap grooves. Forms the length of the attached structure, thereby forming a “C” shape. The inner and outer surfaces of the flange 53 are substantially flat. In some embodiments, the grooved structure 50 is referred to as a C channel 50.

  In the exemplary embodiment shown, the C channel 50 is secured to the joist 140 using a deck retainer 58 between the joist 140 and the C channel 50. The deck retainer 58 is a substantially linear solid structure that provides force from the second structure 200 that is integrated with the foundation structure 100 using the integrated assembly 300 along the joist 140. Specifically, it is transmitted to the joist code 144 and distributed. When the joist socket 60 is used on the end joist, a toe board may be used instead of the deck retainer 58.

  In the exemplary embodiment shown in FIG. 12, two deck holders 58 are required to span the length of the joist 140 while one C channel 50 is used. In a further embodiment, the deck retainer 58 and C-channel 50 are of any length as long as the respective holes are aligned with the cage nut 142 of the joist 140 so that the integrated assembly 300 can be secured to the joist 140. There may be.

  The joist socket 60 includes a tubular trunk portion 65 that is structurally integrated as a single unit by a base portion 62 and a supporting pressing member 67. The tubular body 65 is configured to receive a framework 210 from the second structure 200 to integrate the second structure 200 with the substructure 100. In the exemplary embodiment described, the framework 210 is cylindrical and corresponds to the tubular barrel 65 of the joist socket 60. However, it should be understood that the shape and size of the tubular body 65 may vary to accommodate any shape of the framework 210 of the second structure 200 or the second structure unit 220.

  A T-bolt 70 with a nut 78 secures the joist socket 60 in the C channel 50 while still allowing the joist socket 60 to slidably engage the C channel 50. As used herein, slidably engaged means that the two components (i.e., the joist socket and the C channel) are secured together in a manner that allows mutual sliding movement. To do. As shown in FIGS. 16 and 17, the T-bolt 70 has a T-shape so that the bolt head 72 is shaped to slide within the C-channel 50 and engage the inner surface of the flange 53. Have When the joist socket 60 is in the desired position on the C channel 50, the nut 78 is tightened on the T-bolt 70 to lock the joist socket 60 in place. When the nut 78 is loosened, the T-bolt can slide freely within the linear gap of the C channel 50 and the joist socket 60 is thus slidably engaged with the C channel 50.

  As shown, hole 69 in joist socket 60 aligns with a hole in a supported work platform system component, such as a leg, to secure the supported work platform system to suspended work platform system 100. To do.

  In the exemplary embodiment shown, the joist socket base 62 has a width that is slightly wider than the width of the C-channel 50 and is long enough to support one tubular barrel 65. However, the joist socket base 62 may be of any length so as to include one or more tubular barrels 65, and the diameter of the tubular barrel 65 is for a supported working engagement with the joist socket 60. It may be understood that it depends on the dimensions of the platform system legs or other components. Further, the width of the joist socket base 62 may vary within an acceptable range depending on the diameter of the tubular body 65, but the T-bolt 70 must still fully engage the base 62. Keep in mind.

  As will be appreciated by those skilled in the art, when the second structure 200 is integrated with the foundation structure 100, the framework 210, such as the legs of the second structure, needs to be weighted to the joist 140. The most robust portion of the joist 140 is the panel point 144 (shown most clearly in FIGS. 14A and 14B) where the diagonal support member 38 intersects. Traditionally a dunnage material such as an I-beam or other support material is placed on the joist 140 to transmit the load of the second structure to the panel point 144. However, as discussed above, such a dunnage system prevents downward movement and provides little resistance to horizontal, vertical and rotational movement. Therefore, an additional fixing device (ie, a binding material, a pressing material, a supporting wire, etc.) is used to more reliably support the second structure on the substructure.

  By fixing the deck retainer 58 and the grooved structure 50 directly and parallel to the upper surface of the joist 140, the load of the supported work platform system is concentrated in the joist socket 60, and the grooved structure 50 causes the panel point. 144. Furthermore, since the joist socket 60 completely surrounds the end portion of the framework member of the supporting work platform system, movement in all directions (including rotational movement) is prevented.

  In the illustrated exemplary embodiment, the access structure integrated assembly 300 secures the second structure 200 to prevent or limit movement other than in the downward direction. For example, in the exemplary embodiment described, the joist socket 60 is configured such that when the joist socket 60 is secured to the grooved structure 50, the movement of the secured framework 210 can be moved relative to the joist 140 in the x, y, and z axes. In all directions along the axis, a total of six potential movement types are prevented, including those of rotation in each axis. However, in a further exemplary embodiment, the integrated assembly 300 may limit or prevent movement in at least one, preferably at least two, and more preferably at least three of the above directions. However, in the most preferred embodiment, all six types of movement of the frame member 210 (and hence the second structure 200) relative to the joist 140 (and hence the substructure 100) are limited or prevented by the integrated assembly 300.

  14A and 14B show an exploded view of a joist 140 with an access structure integrated assembly 300. In the illustrated exemplary embodiment, the integrated assembly 300 includes a joint socket 60 and a grooved structure 50, which is a C channel in the illustrated exemplary embodiment. The bracket showing the integrated assembly 300 as shown in FIGS. 14A and 14B includes a nut 78, a T-bolt 70 and a deck retainer bolt 57, although these components are integrated as described herein. It will be understood that it does not form an integral component of the assembly 300. Other securing components and mechanisms may be used to secure C channel 50 (and deck retainer 58, if used) to joist 140, and joist socket 60 is a structure and component other than T-bolt 70. May be used to slidably engage the C channel 50.

  A hole 56 (not shown) in the bottom portion 51 of the C channel 50 is aligned with a hole 59 in the deck retainer 58 (or towboard). The deck retainer bolt 57 secures the C channel 50 to the deck retainer 58 and the joist 140 by engaging a cage nut 142 attached to the joist 140.

  The T-bolt 70 may be inserted into the hole 64 in the base 62 of the joist socket 60 to partially engage the nut 78. The joist socket 60 slides over the end of the C channel 50 so that the head 72 of the T bolt 70 is in the C channel 50 with the T bolt 70 loosely and slidably engaged in the hole 64. It may be moved. The head portion 72 of the T bolt 70 is wider than the opening of the C channel 50 so that the T bolt head portion 72 engages the inner surface of the flange 53. The upward movement of the joist socket 60 relative to the C channel 50 is thereby prevented. Once the joist socket 60 is in the desired position along the C channel 50, the nut 78 is tightened on the T-bolt 70 to secure the joist socket 60 in place using compressive force.

  FIG. 15 is an isometric view of the joist socket 60 showing a tubular body 65 with a hole 69 for engaging a structural element of a supported work platform system. The base portion 62 includes a hole 64 for receiving the T-bolt 70 and a supporting pressing member 67 for structural integrity. In some exemplary embodiments, the base 62 may include additional holes 64 for the T-bolts 70 and the retainer 67 may be of different sizes or configurations.

  FIG. 16 is an end view of the assembled integrated assembly 300. The tubular body 65 is hollow, and a hole 69 is opened to the hollow tubular body 65. The T-bolt 70 extends through the base 62 and the opening in the grooved structure 50, which is a C channel in the illustrated exemplary embodiment. Bolt head 72 is wider than the opening of C channel 50 and thus engages flange 53 when tightened in place by nut 78. 17 is an exploded view of the integrated assembly 300 of FIG.

  FIG. 18 is a side view of the integrated assembly 300 secured to the joist 140. The deck retainer bolt 57 passes through the grooved structure 50 and deck retainer 58, which in the illustrated embodiment is a C channel, to secure the C channel 50 to the joist 140, and the cage nut 142 of the joist 140. Extending into. 19 is an exploded view of the integrated assembly 300 with the deck retainer 58 of FIG. FIG. 19 shows the hole 59 in the deck retainer 58 having a ridge around the lower side of the hole 59. As more clearly shown in FIG. 18, the ridge around the hole 59 fits between the two L-shaped angle steel pieces 39A, 39B of the elements 32, 33 and provides additional stability.

  FIG. 20 illustrates an exemplary second structure 200 that is integrated with the substructure 100 shown in FIG. 11 using the access structure integration assembly 300. In the exemplary embodiment shown, the framework 210 of the second structure 200 includes interconnected legs that are secured to the joist socket 60. Preferably and as shown in FIG. 20, the second structure 200 is a work platform system, such as a supported work platform system that includes a plurality of individual units 220.

  In the exemplary embodiment shown, the substructure 100 includes a plurality of units 120 and the second structure framework 210 includes a plurality of interconnected legs and is configured to define a plurality of individual units 220. Is done. In further exemplary embodiments, the substructure 100 may be only one unit 120 or more than one unit 120. In further exemplary embodiments, the second structure 200 may be configured to be one unit 220 or have a framework 210 that defines one unit 220. In a further exemplary embodiment, the framework 210 of the second structure 200 may secure the platform.

  With the legs of the frame 210 secured in the joist socket 60, movement of the second structure 200 is prevented with respect to the joist socket 60 along the x, y and z axes and with respect to rotation about each axis. The With the joist socket 60 secured to the C channel 50 (ie, clamped to the C channel so as not to move), the movement is relative to the substructure 100 along the x, y and z axes and around each axis. Is prevented with respect to rotation. Accordingly, the access structure integrated assembly 300 effectively integrates the substructure 100 and the second structure 200. As used herein, and when referring to a suspended work platform or platform system that supports a supported work platform or platform system, the term “integrated” refers to a supported work platform or It means that all six movement forms of the platform system (ie linear movement along the x, y and z axes and rotational movement around the x, y and z axes) are prevented.

  However, since the joist socket 60 can move along the C channel 50 when not secured in place, the second structure 200 can be built on the foundation structure 100 in a convenient position and slid to the final position after assembly. be able to. Similarly, the second structure 200 can be constructed and slid to different positions on the substructure 100 to access the various structures at various points along the substructure 100 as desired.

  Since the access structure integrated assembly 300 transmits the pressure exerted by the framework 210 of the second structure 200 to the panel point 144, the size of the second structure 200 is determined by the joist 140 of the suspended work platform system 100. Limited by the amount of weight that can be tolerated. For example, when the substructure 100 is a suspended work platform system and the second structure 200 is a support work platform, the support work platform is a heavy load on which the joist 140 is applied by the support work platform system. One floor or multiple floors may be included as long as they continue to support the height and pressure.

  FIG. 21 illustrates an exemplary substructure 100 that is a suspended work platform system with a second structure 200 that is a supported work platform system. In the embodiment shown, the substructure 100 is suspended from the structure 90, which is an oblique beam. As shown, the second structure 200 uses the integrated system 300 to provide access not only to the underside of the structure 90 but also to the lateral portions of the structure 90 between the suspended work platforms. It is integrated with the foundation structure 100.

  FIG. 21 also shows that the substructure 100 can be integrated with and dependent on the second structure 200. For example, as shown in FIG. 21, the substructure 100 can be an articulatable suspended work platform system, where the suspended work platform system 100b is constructed from a supported work platform system 200a, and Suspended work platform system 100c is constructed from a supported work platform system 200b as described in connection with FIGS. Thus, in order to continue to access the structure 90 on the support work platform 200c, the worker assembles an additional suspended work platform from the support work platform 200c as described in FIGS. Subsequently, an additional supported working platform system can be assembled that is integrated with the new suspended platform system as described herein.

  FIG. 22 illustrates a further exemplary embodiment of substructure 100 integrated with second structure 200 using access structure integrated assembly 300. In the exemplary embodiment shown, the substructure 100 is a suspended work platform assembly and the second structure 200 is a supported work platform assembly. The substructure 100 is suspended from an overhead structure (not shown) and used to access the substructure 91. For example,

  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 constructed above the foundation structure 100. In the exemplary embodiment shown in FIG. 22, six floors of a supported work platform are secured on the foundation structure 100. As shown in FIG. 22, the floors of the supporting work platform system are parallel to each other but are not on the same plane. The number of floors of the second structure 200 integrated with the foundation structure 100 as described above will vary depending on the work being performed and the maximum amount of weight that the joist 140 can support. obtain.

  FIG. 23 illustrates an exemplary embodiment of a foundation structure 100 having an access structure integration assembly 300 that integrates a second structure 200, where the foundation structure 100 is a suspended work platform system. The second structure 200 is a support type work structure system. The supported work platform system is constructed upward from a suspended work platform system secured below the structure 90, which structure 90, in the embodiment shown, for example, a part of a bridge or offshore drilling rig, etc. It is a structure that spans two points. As shown, the substructure 100 is suspended below the structure 90 and extends outside the installation surface of the overhead structure 90. The second structure 200 is constructed upward from a portion of the foundation structure 100 that is not directly under the structure 90 in order to access the side of the structure 90.

  In a further embodiment, the second structure may be integrated with the substructure to provide support for an object such as a tarpaulin or barrier as shown in FIG. In FIG. 24, the second structure 200 is integrated with the substructure 100 using the integrated assembly 300, and the second structure is used to fix the barrier 95 which is a waterproof sheet. For example, when painting the structure 90, the barrier 95 prevents debris (e.g., dirt, dust, water, pollen) from entering the work area and compromising or interrupting the painting or drying process. Barrier 95 also prevents contaminants (eg, odors, vapors, particles) from escaping from the work area and entering the environment. The second structure 200 is therefore used on site to create a factory-like condition.

  The figures and descriptions provided herein show a substructure 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. Although shown, it will be appreciated that the integrated assembly 300 may be used to integrate various substructures and second structures.
