Description

Technical Field

[0001] The present disclosure relates to a space frame assembly that can be used as a building member in forming floors, roofs, and walls, or as a work platform and access system for construction and maintenance of buildings, bridges, and other structures, for example. More specifically, the present disclosure relates to a system of modular components that can be assembled to provide a space frame that can be easily adapted to various sizes and configurations.

Background Art

[0002] In the construction industry, there are many applications where a space frame assembly that is easy to assemble and disassemble is desirable. Some examples are temporary floors, walls, and roofs, and also work platform systems used to perform construction and maintenance tasks on various parts of buildings, bridges, and other structures. Space frame assemblies used in the past have typically been constructed such that the tasks involved can be performed on one part of a building or structure at a time.

[0003] Work platform systems using modular components have been introduced previously (including, for example, U.S. Patent No. 5,214,899), which provide a modular space frame that utilizes a limited number of interchangeable components to form frame assemblies of various sizes and configurations. However, such modular work platforms require a lot of labor to assemble. Further, such platforms are generally designed to use the minimum number of components necessary to achieve the desired maximum capacity. However, in some cases, only a portion of the platform will be subjected to particularly high loads.

[0004] Accordingly, in view of the foregoing, it would be advantageous to provide a space frame system, a work platform system, or other structure that addresses one or more of the above-mentioned drawbacks or other problems. SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE INVENTION

[0013] Specific preferred embodiments of the present invention will be shown and described in detail, but it should be understood that various modifications and variations can be made without departing from the scope of the appended claims. The scope of the present invention is in no way limited to the number of constituent components, their materials, their shapes, their relative arrangements, etc., and is merely disclosed as examples of embodiments. The features and advantages of the present invention are illustrated in detail in the accompanying drawings, and like reference numerals refer to like elements throughout the drawings.

[0014] As a prelude to the detailed description, it should be noted that, as used in this specification and the appended claims, the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise.

[0015] As used herein, the term "single section or unit of a modular space frame support system" and related phrases refer to a planar structure composed of at least three interconnected structures and a plurality of elongated structural members, the plurality of elongated structural members connecting at least three interconnected structures and forming a framework capable of supporting at least one planar deck platform. With respect to a "single section or unit of a modular space frame support system", the terms "section" and / or "unit" may be used interchangeably. Moreover, adjacent sections of a unit of a modular space frame support system may be capable of sharing one or more components, for example, it will be recognized that two adjacent sections of a modular space frame support system may be capable of sharing one or more interconnected structures and one elongated structural member or cord.

[0016] As used herein, the term "multi-level" and related phrases refer to a structure having two or more individual sections separated by a predetermined vertical distance. Generally, each level of a "multi-level" structure will be approximately horizontal or generally within a horizontal plane.

[0017] The term "stress" refers to the degree of tension or compression to which a material or structure is subjected.

[0018] The term "span" refers to the distance between supports. When used with reference to a multi-level structure where the individual levels are generally horizontal or within a generally horizontal plane, the supports are generally vertically oriented structures between one or more levels of the multi-level structure or between one or more levels of the multi-level structure and an independent structure (such as a building, bridge, etc.). As used herein, "support" generally refers to vertically oriented support members, diagonal cords, and suspension components, such as suspension connectors / suspension connector assemblies.

[0019] As used herein, the term "section" refers to the physical property of a structure (such as an elongated structure like a beam, joist, cord, etc.) that determines how much it can resist bending.

[0020] Figures 1 and 2 illustrate exemplary embodiments of a framework, which is a modular space frame support system 100 made from interconnected structures and elongated structural members, and the elongated structural members extend horizontally and diagonally between the interconnected structures to form a framework for a plurality of deck platforms 50. The embodiments shown in Figures 1 and 2 have an upper framework level 110 and a lower framework level 120, each of which is constructed from a plurality of interconnected structures 10' and upper and lower elongated structural members 30' and 70'' respectively. Levels 110 and 120 are joined by diagonal elongated structural members 70'.

[0021] As shown in FIGS. 1 and 2 and further supported by the descriptions of the individual components, there are virtually no limitations regarding the size and shape of the modular space frame support system and the work platform system that can be fabricated in accordance with the present disclosure. FIGS. 1 and 2 show a top perspective view and a bottom perspective view, respectively, of one large rectangular embodiment of the modular space frame support system 100 with the work platform 50 in place for fabricating the work platform system 200, although other common shapes and geometries are contemplated herein.

[0022] Interconnection structure FIGS. 3 - 8 illustrate the interconnection structure 10 / 10'. The interconnection structure is any structure that connects one or more elongated structural members (such as nodes, posts, columns, centers, or shafts, etc.).

[0023] The exemplary interconnection structure 10 shown in FIG. 3 includes an upper element 11 and a bottom element 12 spaced at the distal ends of the intermediate section 15. The upper element 11 and the bottom element 12 are substantially planar in configuration and can be parallel to each other. In the illustrated embodiment, the upper element 11 and the bottom element 12 are octagonal in plan. The intermediate section 15 can be a cylindrical section, and the longitudinal axis of the intermediate section 15 is perpendicular to the planes of the upper element 11 and the bottom element 12. A plurality of openings 13, 14 exist, and the plurality of openings 13, 14 extend through both the upper element 11 and the bottom element 12, respectively.

[0024] At the center of the upper element 11, there is a central opening 16. Due to its central opening area 19 with four slots 17 (e.g., 17A, 17B, 17C, 17D) extending from the central opening area 19, the central opening 16 can generally be cross-shaped in configuration. A series of cross slots 18A, 18B, 18C, 18D traverse and are interconnected with each of the four slots 17A, 17B, 17C, 17D. For additional strength, a second reinforcing plate 20 is added on the lower side of the upper element 11, and the openings above the reinforcing plate 20 correspond to the central opening 16 configuration and all its attendant openings (17, 18, 19). A handle 22 is optionally added to the side of the intermediate section 15.

[0025] Figures 4 - 8 illustrate a second embodiment of the interconnect structure 10'. The interconnect structure 10' includes a first element 11' and a second element 12' spaced apart at the distal end of a tubular section 15'. The first element 11' and the second element 12' are substantially planar in configuration and can be parallel to each other. In the illustrated embodiment, the first element 11' and the second element 12' are generally square in plan. In other embodiments, the first element 11' and the second element 12' can have other shapes (e.g., octagonal, polygonal, circular, etc.).

[0026] The tubular section 15' can be a cylindrical section, and the longitudinal axis of the tubular section 15' is perpendicular to the plane of the first element 11' and the second element 12'. The tubular section 15' can define a predetermined length and inner diameter. In one embodiment, the length of the tubular section 15' can be less than the length of the intermediate section 15 of the interconnect structure 10.

[0027] The tubular section 15’ can define a substantially uniform cross-section along its length. In the illustrated embodiment, the tubular section 15’ is a straight circular cylinder. However, in alternative embodiments, the tubular section 15’ can have different shapes (such as any prism with polygonal faces, etc.). The tubular section 15’ can have a hollow interior.

[0028] There are a plurality of openings 13’, 14’, and the plurality of openings 13’, 14’ extend through both the first element 11’ and the second element 12’ respectively. The plurality of openings 13’ (such as 13A’, 13B’, 13C’, 13D’, 13E’, 13F’, 13G’, 13H’) are scattered on the first element 11’ and are adapted to provide various locations for connecting to one (or a plurality of) elongated structural members 30’. The plurality of openings 14’ (such as 14A’, 14B’, 14C’, 14D’, 14E’, 14F’, 14G’, 14H’) are similarly spaced on the second element 12’, and respective openings (such as 13A’ and 14A’) are coaxial.

[0029] There is a central opening 16’ at the center of the first element 11’. A corresponding opening 23’ is shown at the center of the second element 12’ in FIG. 7. In certain embodiments, the central openings 16’ and 23’ receive a threaded cartridge 800 (see, for example, FIG. 8). In other embodiments, the central openings 16’ and 23’ receive an elongated structural member (such as a vertical support member 75, etc.). The central openings 16’ and 23’ can generally be circular in configuration.

[0030] The interconnect structure 10' has one or more cord engagement structures 78b' adapted to engage the end of an elongate structural member 30 or cord 70. According to one embodiment, at least one cord engagement structure 78b' includes two plates 79a', 79b' configured to engage the end of an elongate structural member 30 or cord 70. Specifically, plates 79a', 79b' each include openings 76a', 76b' that correspond to form a linear passage through plates 79a', 79b' and are coaxial.

[0031] In one embodiment (where one or more cord engagement structures 78b' adapted to engage the end of an elongate structural member 30 or cord 70 are plates 79a', 79b'), plates 79a', 79b' can generally be arcuate in shape. In another embodiment (where one or more cord engagement structures 78b' adapted to engage the end of an elongate structural member 30 or cord 70 are plates 79a', 79b'), plates 79a', 79b' can generally be circular in shape. In such embodiments, the opening 76' can be positioned at the center of the plate 79'. The opening 76' is set at a predetermined distance away from the second element 12' of the interconnect structure 10'. The particular shape and configuration of plates 79a', 79b' can vary depending on the particular arrangement of the modular space frame support system and the particular design of other components used. For example, although plates 79a', 79b' described herein are generally arcuate or circular in shape, in other embodiments, plates 79a', 79b' can take on different polygonal shapes or even circular or triangular shapes. In further embodiments, openings 76a', 76b' can be positioned at different spots on plates 79a', 79b'. In particular, in one alternative embodiment, plates 79a', 79b' can be symmetric.

[0032] As shown in FIG. 8, the interconnect structure 10' can utilize a fixing structure 810 corresponding to a threaded cartridge 800. The threaded cartridge 800 has a tubular member 820 with a first outer portion 822 and a second outer portion 824. The threaded cartridge 800 can further include a threaded inner portion 826 (not shown). As shown in FIG. 8, the first outer portion 822 is generally smooth, and the second outer portion 824 has a fixing structure - engaging structure 826, which is a threaded surface in the illustrated embodiment. The first outer portion 822 defines a predetermined length and outer diameter. The length and outer diameter of the first outer portion 822 correspond to the length and inner diameter of the tubular section 15', such that when the threaded cartridge 800 is inserted into the tubular section 15', the second outer portion 824 is exposed beyond either the first element 11' or the second element 12' and can engage the fixing structure 810.

[0033] elongate structural member "Elongate structural member" refers to any generally linear length of material that can be connected to the interconnect structure to construct a framework for a modular space frame support system. Elongate structural members can take several forms, and in some embodiments, elongate structural members can be specifically designed for horizontal use, diagonal use, and / or vertical use. Further, in some embodiments, horizontal elongate structural members can be specific to upper or lower frameworks. In alternative embodiments, a single elongate structural member can be configured to be used universally in the framework (i.e., used as two or more of a horizontal, vertical, and diagonal elongate structural member).

[0034] Figure 9 shows a top perspective view of a first elongated structural member 30, which is for use with the interconnecting structure 10 and is shown connected to the interconnecting structure 10. The elongated structural member 30 includes an upper element 32 and a bottom element 33. Disposed between the element 32 and the element 33 are a plurality of diagonal support members 38. Each of the elements 32, 33 is made from two L-shaped pieces of channel steel 39A, 39B. The elements 32, 33 can typically be identical with respect to construction, except that the upper element 32 includes connector holes 54A, 54B therein. The elongated structural member 30 includes a first end 31A and a second end 31B. Upper connection flanges 35 and lower connection flanges 36 extend at either end 31A, 31B of both the upper element 32 and the bottom element 33. Connection holes 37 pass through both the upper and lower connection flanges 35, 36. Inside each of the connector holes 37A, 37B, 37C, 37D are additional locking holes 360A, 360B, 360C, 360D, and the additional locking holes 360A, 360B, 360C, 360D are also positioned above the connection flanges 35A, 35B, 35C, 35D. The elongated structural member 30 of FIG. 9 can generally be referred to as a joist, or an open web beam or joist. Such an elongated structural member is generally used as a horizontal member for the upper or lower framework of a modular space frame support system.

[0035] Figures 10 to 13 show a second embodiment of the elongated structural member 30'. The elongated structural member 30' includes a first end 31a' and a second end 31b'. The elongated structural member 30' includes a plurality of upper connection elements 1000 and lateral connection elements 1010. Each of the elements 1000, 1010 is made of a channel steel. The elements 1000, 1010 can be identical with respect to construction, except that typically the lateral connection elements 1010 include connector holes 1012 in their respective middles. A handle 1020 is optionally added to the side of the elongated structural member 30'.

[0036] In the embodiment shown, the elongated structural member 30' is made of a structural tubing. In some embodiments, the elongated structural member 30' is in a single structural tubing shape, however, in other embodiments, the elongated structural member 30' can be made of a plurality of pieces of structural tubing shape or other suitable shapes and materials.

[0037] Specifically, in the embodiment shown, the elongated structural member 30' is a square tube-shaped structure having two open ends 31a', 31b' configured to be directly or indirectly fixed to the interconnecting structure 10. According to some embodiments, the elongated structural member 30' is configured to be directly fixed to the interconnecting structure 10. However, in other embodiments, the ends 31a', 31b' of the elongated structural member 30' include one or more structures adapted to engage the interconnecting structure 10, as will be described in more detail below.

[0038] According to one embodiment, two plates 72a’, 72b’, 72c’, 72d’ are fixed to each of the open ends 31a’, 31b’. At a given end, the plates are fixed to the outer surfaces on both sides of a square tubular structure, and the respective plates 72a’, 72b’ and 72c’, 72d’ are parallel to each other. Each of the plates 72a’ - 72d’ extends outward from the respective ends 31a’, 31b’ of a cord parallel to the elongated structural member 30’. Each of the plates 72a’ - 72d’ further includes openings 73a’, 73b’, 73c’, 73d’ which are positioned through the respective plates, and the pairs of openings 73a’, 73b’ and 73c’, 73d’ of the respective plates 72a’, 72b’ and 72c’, 72d’ correspond and are coaxial, forming a linear passage through each of the plates. Each pair of the openings 73a’, 73b’ and 73c’, 73d’ receives a pin for fixing into the interconnecting structure 10.

[0039] In the illustrated embodiment, the plates 72a’, 72b’, 72c’, 72d’ are generally diamond-shaped with rounded tips. However, it is understood that the specific shape and size of the plates 72a’ - 72d’ can vary depending on the specific arrangement and components used in forming the modular space frame support system. For example, the plates 72a’ - 72d’ can be truly rectangular, round, arcuate, or of any polygonal shape. Similarly, in the illustrated embodiment, the openings 73a’ - 73d’ are shown centered near the rounded ends of the plates 72a’ - 72d’, but in other embodiments, the openings 73a’ - 73d’ can be offset or otherwise differently positioned.

[0040] In another embodiment, the opening can be formed within the elongated structural member 30' itself. In such an embodiment, the elongated structural member 30' has four openings, and two aligned coaxial openings at each end of the elongated structural member 30' form two passages through the entire elongated structural member 30'. The corresponding interconnecting structure will be designed to include a protrusion containing the corresponding one or more openings, which can either be inserted into the hollow central portion of the elongated structural member 30' or form a cup into which the end of the cord is inserted.

[0041] The elongated structural member 30' shown in the figure is made of elements of a specific shape, but it should be apparent to those skilled in the art that there are other embodiments (such as joists, trusses, or structural steel (i.e., I-beams, C-beams, etc.)) that provide aspects of the present invention. Also, the elongated structural member 30' can be made of structural steel (such as wide flange elements, narrow flange members, etc.) or other suitable shapes and materials.

[0042] Such an elongated structural member 30' as shown is generally used as a horizontal member and is generally used in constructing the upper framework, as will be described in more detail.

[0043] FIG. 14 shows a perspective view of an embodiment of a further embodiment of the elongated structural member 70. The elongated structural member 70 is generally used as a horizontal or diagonal member of the lower framework of a modular space frame support system. Thus, such an elongated structural member is generally referred to as a cord 70. When used in connection with the elongated structural member 70, the terms "elongated structural member" and "cord" can be used interchangeably. In the embodiment shown, the cord 70 is an elongated tubular member adapted to support or bear a load.

[0044] In the illustrated embodiment, the cord 70 is made from structural tubing. Specifically, in the illustrated embodiment, the cord 70 is a square tube-like structure having two open ends 71a, 71b configured to be directly or indirectly fixed to the interconnect structure 10.

[0045] According to one embodiment, two plates 72a, 72b, 72c, 72d are affixed to each of the open ends 71a, 71b. At a given end, the plates are affixed to the outer surfaces on both sides of the square tube-like structure such that the respective plates 72a, 72b and 72c, 72d are parallel to each other. Each of the plates 72a - 72d extends outwardly from the respective ends 71a, 71b of the cord parallel to the cord 70. Each of the plates 72a - 72d further includes openings 73a, 73b (not shown), 73c, 73d (not shown) positioned through the respective plates, and the pairs of openings 73a, 73b (not shown) and 73c, 73d (not shown) of the respective plates 72a, 72b and 72c, 72d correspond and are coaxial and are configured to form a linear passageway through the respective plates. Each pair of openings 73a, 73b (not shown) and 73c, 73d (not shown) receives a pin for fixing into the interconnect structure 10.

[0046] Figures 15 - 18 show further embodiments of the elongated structural member 70. Such an elongated structural member is generally used as a horizontal member of the lower framework of a modular space frame support system. As such, in some embodiments, the elongated structural member is referred to as a bottom cord 70'.

[0047] The bottom cord 70’ is an elongated tubular member adapted to support or bear a load. In the illustrated embodiment, the bottom cord 70’ is made from structural tubing. The bottom cord 70’ includes a first end 71a’ and a second end 71b’. A handle 1500 is optionally added to the side of the bottom cord 70’.

[0048] In one embodiment, the bottom cord 70’ is in a single structural tubing shape, however, in other embodiments, the bottom cord 70’ can be made from a plurality of pieces of structural tubing shape or other suitable shapes and materials.

[0049] Specifically, in the illustrated embodiment, the bottom cord 70’ is a square tubular structure having two open ends 71a’, 71b’ configured to be directly or indirectly fixed to the interconnect structure 10. According to some embodiments, the bottom cord 70’ is configured to be directly fixed to the interconnect structure 10. However, in other embodiments, the ends 71a’, 71b’ of the bottom cord 70’ include one or more structures adapted to engage the interconnect structure 10 as will be described in more detail below.

[0050] According to one embodiment, two plates 72a'', 72b'', 72c'', 72d'' are fixed to respective open ends 71a', 71b'. At a given end, the plates are fixed to the outer surfaces on both sides of a square tubular structure, and the respective plates 72a'', 72b'' and 72c'', 72d'' are parallel to each other. Each of the plates 72a'' - 72d'' extends outwardly from respective ends 71a', 71b' of cords parallel to the bottom cord 70'. Each of the plates 72a'' - 72d'' further includes openings 73a'', 73b'' (not shown), 73c'', 73d'' (not shown), and the openings 73a'', 73b'', 73c'', 73d'' are positioned through the respective plates, and the pairs of openings 73a'', 73b'' (not shown) and 73c'', 73d'' (not shown) of the respective plates 72a'', 72b'' and 72c'', 72d'' correspond and are coaxial and are adapted to form a linear passage through each plate. Each pair of the openings 73a'', 73b'' (not shown) and 73c'', 73d'' (not shown) receives a pin for fixing into the interconnecting structure 10.

[0051] In the embodiment shown, the plates 72a'', 72b'', 72c'', 72d'' are generally diamond-shaped with rounded tips. However, it is understood that the specific shape and size of the plates 72a'' - 72d'' can vary depending on the specific arrangement and components used in forming the modular space frame support system. For example, the plates 72a'' - 72d'' can be truly rectangular, round, arcuate, or of any polygonal shape. Similarly, in the embodiment shown, the openings 73a'' - 73d'' are shown centered near the rounded ends of the plates 72a'' - 72d'', but in other embodiments, the openings 73a'' - 73d'' can be offset or otherwise differently positioned.

[0052] In another embodiment, the opening can be formed within the bottom cord 70' itself. In such an embodiment, the bottom cord 70' has four openings, and two aligned coaxial openings at each end of the bottom cord 70' form two passages through the entire bottom cord 70'. The corresponding interconnect structure will be designed to include a protrusion containing the corresponding one or more openings, which can either be inserted into the hollow central portion of the bottom cord 70' or form a cup into which the end of the cord is inserted.

[0053] The bottom cord 70' can be used in the lower frame 120 of the modular space frame support system 100 in the modular space frame support system 100. In such an embodiment, it will be recognized that the work platform 50 is not fixed to the lower frame 120, and the work platform system 200 resulting from constructing using the modular space frame support system 100 will be a single-level work platform system.

[0054] Figures 19 - 22 show a further elongated structural member 70, which in the embodiment shown is generally used as a diagonal member of the modular space frame support system and is thus referred to as the diagonal cord 70''. The diagonal cord 70'' is an elongated tubular member adapted to support or bear a load. The diagonal cord 70'' can be used in the modular space frame support system 100 as a diagonal support. The diagonal cord 70'' includes a first end 71a'' and a second end 71b''. A handle 1900 is optionally added to the side of the diagonal cord 70''.

[0055] In the illustrated embodiment, the diagonal cord 70'' is made from structural tubing. In some embodiments, the diagonal cord 70'' is in a single structural tubing shape, however, in other embodiments, the diagonal cord 70'' can be made from multiple pieces of structural tubing shapes or other suitable shapes and materials.

[0056] Specifically, in the illustrated embodiment, the diagonal cord 70'' is a square tube-shaped structure having two open ends 71a'', 71b'' configured to be directly or indirectly fixed to the interconnect structure 10. According to some embodiments, the diagonal cord 70'' is configured to be directly fixed to the interconnect structure 10. However, in other embodiments, the ends 71a'', 71b'' of the diagonal cord 70'' include one or more structures adapted to engage the interconnect structure 10 as will be described in more detail below.

[0057] According to one embodiment, two plates 72a''', 72b''', 72c''', 72d''' are fixed to each of the open ends 71a'', 71b''. At a given end, the plates are fixed to the outer surfaces on both sides of a square tubular structure, and the respective plates 72a''', 72b''' and 72c''', 72d''' are parallel to each other. Each of the plates 72a''' to 72d''' extends outwardly from the respective ends 71a'', 71b'' of the cords parallel to the diagonal cord 70''. Each of the plates 72a''' to 72d''' further includes openings 73a''', 73b''', 73c''', 73d''', and the openings 73a''', 73b''', 73c''', 73d''' are positioned through the respective plates, and the pairs of openings 73a''', 73b''' and 73c''', 73d''' of the respective plates 72a''', 72b''' and 72c''', 72d''' correspond and are coaxial, and are configured to form a linear passage through each plate. Each pair of the openings 73a''', 73b''' and 73c''', 73d''' receives a pin for fixing into the interconnecting structure 10'.

[0058] In the illustrated embodiment, plates 72a''', 72b''', 72c''', 72d''' are generally triangular and the triangular tips are rounded. However, it is understood that the specific shape and size of plates 72a''' - 72d''' can vary depending on the specific arrangement and components used in forming the modular space frame support system. For example, plates 72a''' - 72d''' can be truly rectangular, round, arcuate, or of any polygonal shape. Similarly, in the illustrated embodiment, openings 73a''' - 73d''' are shown centered near the rounded ends of plates 72a''' - 72d''', but in other embodiments, openings 73a''' - 73d''' can be offset or otherwise positioned differently.

[0059] In another embodiment, the opening can be formed within the diagonal cord 70'' itself. In such an embodiment, the diagonal cord 70'' has four openings, and two aligned coaxial openings at each end of the diagonal cord 70'' form two passages through the entire diagonal cord 70''. The corresponding interconnect structure will be designed to include a protrusion containing the corresponding one or more openings, which can either be inserted into the hollow central portion of the diagonal cord 70'' or form a cup into which the end of the cord is inserted.

[0060] Modular Space Frame Support System FIG. 23 shows a single section or unit 115 of the modular space frame support system 100, which is fabricated using the interconnecting structure 10' and the elongate structural members 30' to form the upper framework, and using the diagonal elongate structural members 70'' and a single interconnecting structure 10' to form the lower framework. Note that the four interconnecting structures 10A', 10B', 10C', 10D' are interconnected with the four elongate structural members 30A', 30B', 30C', 30D'. FIG. 23 shows a single frame unit 115 that is square in plan view. It should be apparent to those skilled in the art that other shapes and configurations can also be fabricated. For example, by varying the length of the elongate structural members 30', other shapes can also be fabricated. For example, a rectangular frame unit 115 can be constructed. Also, by attaching the elongate structural members 30' to the various openings 13', 14' of the interconnecting structure 10', various angles at which the elongate structural members 30' interconnect with the interconnecting structure 10' can be achieved. For example, a frame unit 115 (not shown) that is triangular in plan view can be constructed. Thus, by varying the length of the elongate structural members 30' and / or by varying the angle at which the elongate structural members 30' extend from the interconnecting structure 10', frame units 115 of virtually any shape and size, and as a result, the resulting modular space frame support system 100 and work platform system 200 can be constructed. Further, frame sections or units 115 of different shapes, sizes, and configurations can be joined and abutted to one another, such that the modular space frame support system design (and, the work platform system design) is virtually completely customizable. This adaptability of the modular space frame support system 100 provides a convenient way to gain access to work areas of virtually any shape required in construction.

[0061] FIG. 24 shows a single frame section or unit 115 from FIG. 23, with platform 50A installed on top of a single frame unit 115, thus starting to convert a single frame unit 115 into a single unit of the work platform system 200. In the illustrated embodiment, platform 50A is approximately half the size of the upper frame section and is thus supported along its long edge by elongated structural member 30A’ and along its short edge by elongated structural members 30B’ and 30D’. The remaining long edge is supported by a modified elongated structural member 30E’ which is positioned in the middle of each frame unit 115. When positioned in the middle of frame unit 115, elongated structural member 30’ can provide additional support for supporting platform 50, spans between a pair of elongated structural members 30’ and can be perpendicular to a pair of elongated structural members 30’. There can be pins 53 at either end of such an elongated structural member 30’, which communicate with corresponding connector holes 1012 in the middle of each of the lateral connection elements 1010. The configuration of the upper connection elements 1000 of the intermediate elongated structural member 30’ and the other elongated structural members 30’ is such that vertical and horizontal movement of platform 50A is avoided. For example, as shown in FIG. 25, a deck retainer plate 60 can be installed across the space between a plurality of work platforms 50. The deck retainer plate 60 can include a plurality of holes 62 and a plurality of deck retainer bolts 61 can be used to adhere the deck retainer plate 60 to the elongated structural member 30’. The deck retainer plate 60 is one way to secure the work platform 50 to the modular space frame support system 100.

[0062] The work platform 50 is typically sized to be a piece of 4’’x8’ material. A suitable work platform 50 can be made from metal (e.g., steel, aluminum, etc.), wood, plastic, composite materials, or other suitable materials. Similarly, the work platform 50 can be made from items having a solid, corrugated, grid-like, smooth, or other suitable configuration. For example, the work platform 50 can be wood sheeting, plywood, roofing decking material, metal over a frame, grating, and steel sheeting, etc. Thus, after installing a first work platform 50A on the unit 115 of the modular space frame support system 100, the installer can continue in this manner and install additional work platforms 50A, 50B as shown, for example, in FIG. 25, such that the entire upper frame 110 and / or lower frame 120 is covered by the work platforms 50A, 50B and a complete work platform system 200 is created.

[0063] FIG. 26 shows a side perspective view of the interconnection between a plurality of elongated structural members and an interconnecting structure 10’. In particular, FIG. 26 shows an interconnecting structure 10’ from an upper frame 110 with two elongated structural members 30’ and three diagonal cords 70’’. The interconnecting structure 10’ is used on the upper frame 110, which means that the diagonal cords 70’’ protrude at a downward angle such that they are away from the interconnecting structure 10’.

[0064] FIG. 27 shows a side perspective view of the interconnection between a plurality of bottom cords 70', a plurality of diagonal cords 70'', and the interconnect structure 10'. In particular, FIG. 27 shows the interconnect structure 10' from the lower frame 120, and each interconnect structure 10' engages two bottom cords 70' and four diagonal cords 70''. In the embodiment shown in FIG. 27, the interconnect structure 10' is used on the lower frame 120, which means that the diagonal cords 70'' protrude at an upward angle such that they are away from the interconnect structure 10'.

[0065] As described above, the ends 31', 71', 71'' of the elongated structural member 30', the bottom cord 70', and the diagonal cord 70'' are each configured to engage the interconnect structure 10'. When the elongated structural member 30', the bottom cord 70', or the diagonal cord 70'' is aligned with the interconnect structure 10', the openings 73', 73'', 73''' in the end plates 72', 72'', 72''' of the elongated structural member 30', the bottom cord 70', or the diagonal cord 70'', and the openings 76a', 76b' in the plates 79a', 79b' of the interconnect structure 10' are aligned to form a single continuous passage. The elongated structural member 30', the bottom cord 70', or the diagonal cord 70'' is then fixed to the interconnect structure 10' using a fixing structure (e.g., a pin, nut and bolt configuration, wire and pin, etc.).

[0066] In the specific embodiment shown, the distance between the plates 79a', 79b'' of the interconnect structure 10' is greater than the distance between the plates 72', 72'', 72''' at the ends 31a', 71a', 71a'' of the elongated structural members 30', bottom cord 70', or diagonal cord 70''. Thus, the plates 79a', 79b' of the interconnect structure 10' are outside the ends 31a', 71a', 71a'' of the elongated structural members 30', bottom cord 70', or diagonal cord 70''. However, in an alternative embodiment, the distance between the plates 79a', 79b' of the interconnect structure 10' may be less than the distance between the plates 72', 72'', 72''' at the ends 31a', 71a', 71a'' of the elongated structural members 30', bottom cord 70', or diagonal cord 70'', and the ends 31a', 71a', 71a'' of the elongated structural members 30', bottom cord 70', or diagonal cord 70'' may be slid over the plates 79a', 79b' of the interconnect structure 10'.

[0067] Figures 28 and 29 show further embodiments of a plurality of sections or units 115 of a modular space frame support system 100 made using the interconnect structure 10' and the elongated structural members 30', with a work platform 50 installed over the frame unit 115, thus converting the frame unit 115 into a single unit of a work platform system 200.

[0068] In particular, according to embodiments of the present disclosure, and as shown in FIGS. 28 and 29, the work platform system 200 is shown to include an upper frame 110 having four individual sections or units 115 arranged in a 2x2 configuration. The lower frame 120 is composed of one individual unit in a state where a given interconnect structure 10' of the lower frame 120 is positioned directly below the center of the work platform 50 of the upper frame 110. In other words, the lower frame 120 is smaller than the upper frame 110, and the upper frame 110 overhangs the lower frame 120 on all sides. Regardless of the specific shape and arrangement of the modular space frame support system 100 and the resulting work platform system 200 shown in FIGS. 28 and 29, it is understood that the modular space frame support system 100 and the resulting work platform system 200 can take on a number of shapes, sizes, and configurations with the interconnect structure 10' of the lower frame 120 still positioned directly below the center of the work platform 50 of the upper frame 110.

[0069] In the embodiment shown in FIGS. 28 and 29, the interconnect structure 10' of the lower frame 120 is offset with respect to the interconnect structure 10' of the upper frame 110. However, in a further embodiment, the interconnect structure 10' of the lower frame 120 can be positioned directly below the interconnect structure 10' of the upper frame 110. In such an embodiment, each interconnect structure 10' of the lower frame 120 is interconnected with the bottom cord 70' and the diagonal cord 70'', and can be further connected to the corresponding interconnect structure 10' of the upper frame 110 using vertical support members. The vertical support member is an elongated structural member having a first end configured to engage the bottom element 12 / 12' of the interconnect structure 10 / 10' and a second end configured to engage the upper element 11 / 11' of the interconnect structure 10 / 10'. In some embodiments, the second end can be specifically configured to engage the central opening 16 of the upper element 11 / 11'.

[0070] Regardless of the particular shape and arrangement of the modular space frame support system 100 and the resulting work platform system 200, it is understood that the modular space frame support system 100 and the resulting work platform system 200 can take on a number of shapes, sizes, and configurations with the interconnect structure 10' of the lower frame 120 still positioned directly below one of the interconnect structures 10' of the units 115 of the upper frame 110.

[0071] In a further embodiment, the distance between the upper framework 110 and the lower framework 120 is increased relative to the distance between them in another embodiment. By increasing the distance between the upper frame 110 and the lower frame 120, and thereby increasing the length of the diagonal cord 70'', the load capacity is increased. For example, in the illustrated embodiment, each of the diagonal cords 70'' used in the modular space frame support system 100 has the same length, but in a further embodiment, a portion of the modular space frame support system 100 can utilize diagonal cords having a greater length than the length of another portion (or the remaining portion) of the modular space frame support system 100. The ability to modularly increase the load capacity of portions of the modular space frame support system allows smaller and lighter components to be used for most of the modular space frame support system and allows larger and heavier components to be used only where needed.

[0072] Additional component In some embodiments, the railing can be connected to the upper frame 110. A standard railing is typically elongated and includes a first flange and a second flange extending therefrom for connection to the interconnect structure 10 / 10'. The first flange, like the second flange, has holes therein. By guiding a pin through the upper flange, then down through the holes 13 / 13' in the upper element 11 / 11', through the lower flange, and then through the holes 14 / 14' in the bottom element 12 / 12', an installer can attach a standard railing to the interconnect structure 10 / 10' of the modular space frame support system 100. The pin can include various devices (such as roll pins and retaining loops, etc.). In this way, multiple standard railings can be attached to multiple interconnect structures, making it possible to generate a railing system around the work platform system 200.

[0073] The railing can be made of various materials (such as chains, cables, and lines, etc.). For example, the railing can be a galvanized aircraft cable. A standard railing includes multiple holes. J-bolts can be used with nuts to attach the railing to the standard railing. In some embodiments, additional railings can be added at intermediate points of the standard railing. In other embodiments, the standard railing can also be used to build a work enclosure system. For example, a waterproof sheet or sheeting, etc., can be attached to the standard railing to surround a work area for painting, demolition, asbestos or lead paint removal, and similar activities, where workers do not want to let smoke, paint, hazardous materials, debris, etc. escape from the work area.

[0074] In one particular embodiment, the modular space frame support system 100 includes an upper frame and a lower frame. The upper frame includes at least: a first interconnect structure connected in a fixed relationship to a second interconnect structure using at least a first elongated structural member; a second elongated structural member connectable to the first interconnect structure; a third elongated structural member connectable to the second interconnect structure; a third interconnect structure connected in a fixed relationship to the second elongated structural member; a fourth interconnect structure connected in a fixed relationship to the third elongated structural member; and a fourth elongated structural member connecting the third interconnect structure and the fourth interconnect structure. In some embodiments, at least one of the first, second, third, and fourth elongated structural members is connectable to at least one of the respective interconnect structures using pins.

[0075] The upper frame and the lower frame are connected to each other by at least one of diagonal cords and vertical supports. In some embodiments, the upper frame is connected to the lower frame by a plurality of diagonal cords, each of the diagonal cords being fixed to an interconnect structure of the upper frame at one end and to an interconnect structure of the lower frame at a second end. In some embodiments, the upper frame and the lower frame are connected to each other using both at least one diagonal cord and at least one vertical support.

[0076] In some embodiments, the modular space frame support system has sections greater than 1 foot, or greater than 3 feet, or 5 feet or more. In some embodiments, the modular space frame support system has sections greater than 1 foot, or greater than 3 feet, or 5 feet or more, or 6 feet or more, or 7 feet or more, or 8 feet or more, or 9 feet or more, or 10 feet or more.

[0077] In certain embodiments, the modular space frame support system has a span capacity greater than 20 feet, or greater than 50 feet, or greater than 60 feet, or greater than 70 feet, or greater than 80 feet and up to 100 feet.

[0078] In certain embodiments, the modular space frame support system has a dead load capacity greater than 2 pounds per square foot, or greater than 3 pounds per square foot, or greater than 5 pounds per square foot and up to 7 pounds per square foot.

[0079] Method of building a modular space frame support system Generally, when building a modular space frame support system as disclosed herein, a first frame including a plurality of interconnected structures and elongated structural members is assembled. Then, a second frame is assembled either above or below the first frame depending on the construction of the second frame and is connected to the first frame by one or more diagonal cords and / or vertical supports. In certain embodiments, the assembled first frame is the lower frame and the assembled second frame is the upper frame.

[0080] In some embodiments, and particularly where the modular space frame support system is to be used as a work platform system, a work platform can be installed on the first and / or second frames depending on the particular construction of the first and second frames. As described above, the work platform is generally installed only on the upper frame.

[0081] Next, the first and second frames are fixed to each other. To fix the first and second frames to each other, at least one diagonal cord, a vertical support, or a combination thereof is fixed to the first frame at a first end and to the second frame at a second end.

[0082] It will be recognized that, although repetitive, the particular structure of the first and second frames can affect the steps in assembling / building a modular space frame support system. In a particular embodiment, the first frame is assembled, the second frame is assembled, and a diagonal cord is attached between the first and second frames. In one embodiment, the step of attaching a diagonal cord between the first and second frames is by any of the exemplary methods described above in connection with cords 70 / 70'.

[0083] The way the vertical support is used is different in that after the first frame is assembled, a first end of the vertical support is connected to the interconnecting structure of the first frame, and after the second frame is assembled, a second end of the vertical support is connected to the interconnecting structure of the second frame. The step of installing a work platform on the first frame, as well as the step of attaching a diagonal cord to the first and second frames, are optional steps.

[0084] It will be understood that, although repetitive, the cord used as a diagonal cord to fix the first and second frames can be by any of the embodiments or combinations of embodiments described herein.

[0085] In certain embodiments, one or more suspension connectors (e.g., high strength chains, etc.) are used, if required, to secure the lower frame 120 to a structure (e.g., an overhead structure such as a bridge) before the upper frame 110 is assembled. In this way, the modular space frame support system can be fully suspended from a suitable structure. It should be noted that each interconnecting structure does not necessarily require a suspension connector to be connected to the structure. Once assembled, one or more suspension connectors can be used to secure the upper frame 110 to the structure. Once the upper frame 110 is constructed and secured to the structure using one or more suspension connectors, the suspension connectors from the lower frame 120 can be removed, if desired.

[0086] The suspension connector can be any suitable support mechanism capable of supporting the modular space frame support system 100, the resulting work platform system 200, and all of its attached dead loads, as well as any intended live loads placed on the work platform system 200. The suspension connector can be, for example, a high strength chain or cable. For example, one suitable suspension connector is a 3 / 8’’ grade 100 heat treated alloy chain. The suspension connector is attached to a beam clamp, which is further attached to a plurality of elements on the underside of the structure. The structure can be, for example, a bridge, viaduct, or ceiling structure of a building. Similarly, the elements to which the suspension connector is attached can be beams, joists, or any other suitable structural element of the structure. Instead of a beam clamp, other suitable structure attachment devices can be used.

[0087] The free end of the suspension connector is installed through the central opening area 19 / 19' of the upper element 11 / 11' of the interconnecting structure 10 / 10'. Then, the suspension connector is slid onto and into one of the four slots 17 / 17' (e.g., 17A / 17A'). When the suspension connector is installed in the slot 17A / 17A', the chain retainer pin is installed in the adjacent transverse slot 18A / 18A' so that the suspension connector remains retained in the distal end of the slot 17A / 17A'. The suspension connector and the slot 17A / 17A' are sized and configured such that when a keeper pin is properly installed in the transverse slot 18A / 18A', the suspension connector is effectively locked to the interconnecting structure 10 / 10' and cannot slide vertically or horizontally from its position within 17A / 17A'. This locking system effectively secures the interconnecting structure 10 to the suspension connector.

[0088] An alternative device for connecting a suspension connector to the upper frame 110 or the lower frame 120 of the modular space frame support system 100 is an auxiliary suspender mounting bracket. The auxiliary mounting bracket is typically used when a particular interconnecting structure 10 / 10' is not accessible for connection to the suspension connector. One embodiment of the auxiliary suspender mounting bracket includes two opposing and parallel flanges. An interconnecting tube and a base plate span the flanges. A plurality of mounting holes pass through the base plate. The auxiliary suspender mounting bracket can be used instead of, or in addition to, the interconnecting structure 10 / 10' for a suspension point. The bracket enables the suspension connector to be connected to the modular space frame support system 100 at locations other than the interconnecting structure 10 / 10'.

[0089] One or more obstacles may be positioned beneath the structure or between the structure and the modular space frame support system 100. These obstacles may be artificial or natural. For example, the obstacles can be concrete beams, box beams, inadequately sized frameworks, piping, lighting, and finish surfaces, etc. The obstacles are such that the particular interconnecting structure 10 / 10’ is not practical (or not possible) as a connection point of the modular space frame support system 100 to the suspension connector. In this case, one or more auxiliary suspender mounting brackets can be attached to the elongated structural member. High-strength bolts can be passed through the mounting holes and then through the holes above the upper element and connected to the bolts below the upper element. A suspension connector (e.g., a chain) can be connected to a beam on the underside of the structure via a beam clamp.

[0090] Obstacles that are directly vertically above the interconnecting structure 10 / 10’ can render the interconnecting structure 10 / 10’ inadequate as a suspension point. Thus, a bracket can be attached to the elongated structural member adjacent to the interconnecting structure 10 / 10’, thereby enabling the suspension connector to obtain proper attachment to a nearby beam. The angle between the suspension connector and the vertical direction allows for either the suspension connector to be non-vertical or to be slightly deviated from the vertical direction.

[0091] The modular space frame support systems (and resulting work platform systems) described herein are merely intended as examples, and it should be recognized that the present disclosure is intended to encompass numerous variations of the modular space frame support systems and work platform systems, their components, and / or methods of assembly described above. For example, the modular space frame support systems and work platform systems described herein include two levels 110, 120, but in other embodiments, other numbers of levels may be present.

[0092] Also, the specific shapes of the different structures of a given modular space frame support system and work platform system can vary depending on the use of the modular space frame support system and, when used as a work platform system, the size, shape, and location of the structures accessed using the work platform system. For example, depending on the embodiment, the various levels of the modular space frame support system and work platform system can take any of various rectangular, triangular, or other polygonal shapes (moreover, for example, octagonal, hexagonal, etc.), or even, in some cases, shapes other than polygonal shapes, and further, the individual units or sections of the modular space frame support system and (ultimately) the work platform system can likewise take any of various rectangular, triangular, or other polygonal shapes.

[0093] The materials from which a modular space frame support system and a work platform system can be formed can vary according to the embodiment. For example, suitable materials for such components of a modular space frame support system and a work platform system include, but are not limited to, metals (such as steel, aluminum, etc.), wood, plastic, composites, or other suitable materials. Also, such components can be made from items that are solid, corrugated, lattice-like, smooth, or of other suitable configurations. For example, the work platform 50 of such a work platform system can be made from, among other things, wood sheeting, plywood, roofing decking material, metal over a frame, grating, and steel sheeting. Also, it should be recognized that various types of linkages can be used when supporting the levels of a modular space frame support system and a work platform system relative to other levels and / or relative to another support structure.
