This invention relates to a modular base structure and modular beam structure, and in particular, but not exclusively to modular base structures or modular beam structures for use with or as buildings or stnictures which incorporate shipping containers and or shipping container sized components and to an assembly method.

BACKGROUND

There is often a need to construct temporary structures, for example storage warehouses, workshops, offices or even living accommodation, and increasingly shipping containers. or shipping container sized modules are attempted to be used in these situations.

Shipping containers, and in particular used shipping containers, provide a relatively low- cost structural component that are large and strong enough to form a work or dw elling space by itself, and or to form a structural support for a larger building.

W hen shipping containers are used by themseh es. or perhaps as a series of containers positioned side by side, one of the problems is the lack of insulation, particularly in the roof of the containers. This leads to a number of problems. The interior can heat up during the day. and then become very cold at night. When used for storage, this can lead to sw eating of the stored goods w hen the temperatures are high, followed by condensation of the moisture when the temperature drops. The condensation can produce droplets that rain down, or drain onto the stored goods w hich can cause damage and extra cost.

When shipping containers are used as structural supports for larger buildings, for example to form a w arehouse. an emergency medical centre, a w orkshop or hangar, there is a need for additional structure to form a roof for the building. The construction of the roof section can be extremely difficult and time consuming, and it can be difficult to transport the required building materials. In cases w here the building needs to be erected in a very short time, for example when providing a building in an emergency relief situation, it is important that such transportation and construction difficulties are minimised.

Other problems occur because of the multitude of variations of heights, widths, length containers especially when comparing each side of a building which form the wall which need to be of similar height to allow a roof section to span there between and be level. This problem of different heights or length containers cause some containers to not be able to be used which can further limit the usefulness of all containers as being readily available as part of a building structure. Shipping containers hav e corner castings with twist lock assemblies w hich also vary in size and position on the corners thereby preventing any standard methods of using them with other components of a building other than just connecting to the top of the container which does not provide a standard robust and predictable jointing system that can be relied upon structurally and practically and also does not allow for ready construction or assembly or disassembly.

In this specification unless the contrary is expressly stated, where a document, act or item of knowledge is referred to or discussed, this reference or discussion is not an admission that the document, act or item of knowledge or any combination thereof was at the priority date, publicly available, known to the public, part of common general knowledge; or known to be relevant to an attempt to solve any problem with which this specification is concerned.

For example the shipping or transport container includes a box like structure w ith side w alls defining a width, end walls defining a length, floor to roof or top defining a height, the wall support means can also include simply a wall support which can include for example posts or wall frame. The modular base structure is supported and adjustably connected directly by its corners on the w all support means. At least one modular beam structure is designed to span a distance between wall support means w hich such modular beam structures also have a length, w idth and height w hich can be used as a spanning member or for example a roof truss w hich are supported by shipping container comer castings w ithout loading the container walls. The modular beam structures are sized and dimensioned to be able to be stored or transported on top of each other or overlap or "piggyback ^" and tit within a conventional shipping container and also sized and dimensioned to allow total coverage in a side by side orientation and by end supported on a shipping container.

The components of the present invention which are standardized to allow both easy assembly and easy disassembly and also easy transportation, using the shipping containers to carry most or at least part of the components.

The modular base structures 2 are si/.ed and dimensioned to cover and be supportively connected only to the shipping container comer castings and at the same time connect and support at least an end portion of at least one modular beam structure I in a side by side configuration thereon. The modular base structures 2 are sized to be similar to a roof or base of a shipping container, thereby allow conv enient transport within shipping containers or packed on top of or under a shipping container.

The modular base structure 2 supports at least an end portion of at least one modular beam structure I and each modular beam structure I is for use in spanning a distance between the wall support means (shipping containers which act as one form of the wall support means).

The modular beam member spans between the shipping container and a wall support or another shipping container, by being connectively supported at each end and at. at least one end by one modular base structure 2 connected to the top the shipping container which functions as a wall support for the modular base structure and at an end of the modular beam structure whereby the components of the present inv ention are standardized in shape and structure to allow easy and straightforward assembly and disassembly in relation to any sized shipping container and also in relation to transportation, using the shipping containers to carry most or at least part of the components of the present inv ention.

The invention is in no way limited to these preferred embodiments, as they are purely to exemplify the invention only and that possible variations and modifications would be readily apparent without departing from the scope of the inv ention. Modular Beam Structure I

Each modular beam structure 1 includes an elongate lattice space truss frame structure forming a substantially rectangular tubular box like structure having the follow ing faces of: end faces 6. a top face 7. a bottom face 8. front side face 0 and rear side face 10 with a space 1 1 therein semi enclosed. The front side 0 and rear sides 10 are less in area than the top 7 and bottom 8 with the ends 6 being the smallest area. Though the term rectangular is used this does not necessarily mean that the structure is uniform in that an upper surface is sloped or angled for use as part of a roof structure.

The rectangular structure includes elongate members comprising longitudinal beam members I A. transverse cross beam members I B. diagonal beam members IC and upright members I D connected together. The longitudinal beam members define a length and the transverse beams define a width such that the length and width of the rectangular structure is a multiple of the length of the wall support. The diagonal members are interconnected at the joints of the ends of the transverse members and longitudinal beam members.

The space truss frame structure is formed by interconnected elongate members having an I. -shaped or angle cross section which such members can be oriented at right angles or at an angles or be conjoined to each other to form a certain pattern on each face of the space truss frame structure. In this example front 0 and rear sides 10 can be formed of a spaced rectangular or polygonal 4. side frames and the top 7 can be formed as regular rectangular frames. The bottom 8 can include regular rectangular frames with diagonal bracing members. Each end o of the frame structure can be formed of a rectangular frame with at least one diagonally oriented member.

The space truss frame structure of the tubular box like structure is made up of interconnected upper planar frame 13 and a lower planar frame 14 whereby the lower planar frame is oriented in substantially in a horizontal plane and the upper planar frame is oriented at an angle to the horizontal plane but which is closer to being horizontal than vertical. The upper and lower planar frames 13. 14 are separated by vertical oriented frames 15 of diminishing height 16, together forming the box like structure with an inner space 1 1 therein, and upper corners 17, lower corners 18 and intersections 19 between the elongate members.

The distance between the ends 6 (from outside of castings) defines an outside length and longitudinal direction 20 forming a longitudinal direction and a distance between front side and rear side define an outside width 21 (outside of casting to outside of casting) there between forming a transverse direction. The L-shaped cross section includes an upright portion 23 and base portion 24 whereby in use in this example the base portion 24 is orient at the bottom w hile the upright portion 23 is oriented upright but the L shape faces inwardly of the box like structure.

The tubular box like structure is subdivided into several rectangular box cells 26 having certain distance as a proportion of the total outside length 20 and outside width 21.

Comer casting assemblies are commonly provided at all external corners of transport containers. The corner casting assembly typically includes plate like box shape with horizontal and v ertical walls forming an internal or semi enclosed space therein, with the walls including apertures shaped and/or a twist lock assembly. The twist lock assembly includes an operating handle operatively connected to a protruding member. The handle is located outside of the box abo\ e horizontal walls and the protruding member is located within the space whereby operating the handle causes the protruding member to protrude or not to protrude through the apertures.

Located at the upper 17 and lower 18 corners of the modular beam structure I . there is prov ided a corner casting 27 as seen in figure 6 (without a handle and protruding member) having first horizontal (upper) face 28 separated from a second horizontal (lower) face 2 ^l) by mutually opposite two vertical side faces 30 forming a comer recess 32 therein or there between. F.ach face includes at least one aperture 32 for receipt of a protruding member 27b as part of the twist lock assembly from the modular base structure as shown in figure 4. The twist lock assembly includes a handle member 27c which is operatively connected to the protruding member 27b. Corner cast in us 27 are formed as separate members and are fitted over or as part of the comers of the modular beam structure I with the apertures cut through a flange of transverse cross bean or longitudinal beam members, but equally the corner of the modular beam structure can be formed with a comer gap to receive the comer casting therein.

The orientation of the first horizontal and second horizontal faces will swap depending on w hich corner is being referred to. Each face has at least one aperture there through so that first horizontal 28 and second horizontal face 29 each have an elongate slot 32 at mutually opposing directions to each other and the vertical side faces 30 have smaller elongate slots therein being vertical in orientation. Comer castings 27 are provided at each comers at. at least one end of the tubular box like structure that requires support from the modular base portion and wall support.

There are also pro\ ided non-corner castings 35 located at non-corners or intersections between any lengths of the elongate members ie the transverse cross beam members and longitudinal beam members. Non-corner castings 35 are channel-shaped plate members ha\ ing an upper horizontal face 3b. vertical side face 37 and lower horizontal face 38 with each face having an aperture 39 there through which are in oriented opposite directions. Non-corner castings 35 are provided at a lower and upper portions of the tubular box like structure and in use engage with an upwardly protruding tw ist lock from a lower, corner casting and non-corner casting from the modular base member 2.

Non-comer castings 35 are formed as separate members and are fitted over the or at the ends of the transverse cross members of the modular beam member I w ith the apertures cut through a flange of trans\ erse cross beam and or longitudinal beam members, but equally the ends can be formed with a gap to receive the non-comer casting 35. As shown in the figures for the modular beam structure, none of the upper and lower comer castings and non-comer castings have a twist lock assembly though in other options tw ist locks can be included. Tw ist lock assemblies are provided in the upper comer casting 27 and non-comer castings 35 in the modular base structure. The tw ist locks provide a means for lucking and connecting the comer castings and associate structure together tor simple and quick assembly or disassembly.

The space frame structure of the modular beam structure I , can be sized depending on the spanning distance between wall supports and or the size of wall support ic if the wall support is a 20ft (6059mm) or a 4011 ( 12032 ) shipping container. If the spanning distance is greater than a certain dimension then at least one other modular beam structure I can be end to end connected as required. The dimensions of the modular beam structure I can lie selected to be sized to allow overlapping or not with each other, to be transported within a shipping container or located on top of or below for storage or transport. Modular Base Structure 2

As shown in the figures the modular base structure 2 is a planar shaped rectangular structure with interconnected elongate members comprising longitudinal beam members 40 separated by transverse cross beam members 41. forming three main polygonal cells 42 (eg rectangular or square between outer longitudinal beam members and end transverse cross beam members having a portion of an optional central longitudinal beam member as show n in figure 1 1 ) there between, hav ing two equal spacing width 43 and one smaller spacing width (eg half of each of the other tw o) 43a with the modular base structure 2 designed to in use be oriented substantially horizontally. The longitudinal beam members 40 define a length and the transv erse beam members 41 define a w idth of the modular base structure 2 such that the length and width of the rectangular structure is a certain multiple of the length of the w all support 3.

The modular base structure 2 is designed to be supported by comer castings of the wall support w ithout loading the walls of the w alls support. The modular base structure 2 is used to connect and provide a base for the modular beam structure 1 and or can be used to make up a difference in height of short shipping containers.

The modular base structure 2 includes an elongate lattice space frame structure forming a single planar like structure having the follow ing edge faces of: end faces 45. top face 46. bottom face 47. front side edge face 4S and. rear side edge face 49 whereby a planar area of the top 46 is similar in planar area to the bottom face 47. The outside length 50 is defined as being from end 45 to end 45 (outside of castings) and an outside width 51 is defined as being from side edge 48 to side edge 48.

Λ depth dimension 52 of the modular base structure is defined as extending from the top 46 to the bottom 47 at the castings which w ill be much less in dimension than the width 51 and length 50.

In this example, the elongate lattice space frame of the modular base structure 2 is formed comprising joined or connected elongate members comprising longitudinal beam members 40 including an I-beam or universal beam cross section w ith flanges 40a separated by a w eb 40b and trans\ erse cross beam members 41 include a channel cross section having side walls 53 and base wall 54 and channel recess 55 there between w hereby the channel cross section is oriented on its side w ith side walls 53 oriented horizontally and the base wall 54 being vertical w ith the channel recess 55 being oriented outward facing. The space frame of the modular base structure 2 has at least one cell 42 including an inner bisected space 58 located in between the joined or connected elongate members. The space frame also comprises in use upper comer portion 60 and an adjacent lower corner portion 61 at each comer and intersections 63 at the ends of each cell 42 of the elongate members in the same plane or at v arious angles. Kaeh upper corner portion 60 and lower comer portion 61 have a corner casting 65 therein w ith just an upper or lower horizontal face 67 and mutually opposing vertical side faces 68 with each face having an aperture shaped as an elongate slot 65 A. As show n in figure 28 face 68 can for example have dimensions of 178x 178mm and face 67 can hav e for example area dimensions of say 154.5x 178mm a plate thickness of 4mm. Therefore each outside corner of the modular base structure 2 includes an upper and low er corner castings and each intersection has abutting non-comer castings.

However each intersection 63 has tw o side abutting non-comer castings 70. 71 in the shape of channel- shaped castings w ith a horizontal (top or bottom) face 73 and a v ertical side face 74. Tw o side abutting non comer castings are provided to allow for each end of a module beam structure to be connected to the modular base structure in a side to side abutting relationship. Again, similar to the corner castings 65 and non-comer castings 70. 71 of the modular beam structure I . if the corner castings 65 of the modular beam structure are located on a top comer, then there are top faces whereas if the comer casting is located on a bottom corner, there will be bottom faces.

Each corner casting 27 and non-corner casting 35 of the modular beam structure I and comer casting 65 & non corner casting 70. 71 of the modular base structure 2, provide internal space or recess accessible by each aperture and/or include a twist lock assembly in each. Each twist lock assembly works in the standard way to having rotatable handle lever type member to twist a vertically protruding member through an adjoining aperture to lock or connect the protruding member in place to hold and connect various components together.

As shown in figures 3 and 4 for the modular base structure 2. only the upper comer castings 65 and non-corner castings 70. 71 have the twist lock assembly.

Each shipping container 3 has a box like structure w ith side w alls 81. end walls 82. base 83 and roof 84. As is customary with such shipping containers 3, each shipping container 3 is a rectangular shaped container with comer castings 85 and twist lock assemblies on all in use upper corners but with lower comer castings not having a twist lock assembly. The modular base structure for the 20ft (60%mm) shipping container (see figure 1 1 ) can include three cells with the first two cells 42 being equal in width to the width of one modular beam structure 1 and the last cell 42 being half the w idth of the first tw o cells and modular beam structure 1. When two 20ft ( 6096mm )modular beam structures I are end abutting as shown in figure 9 then one modular beam structure can straddle two abutting half cells to be connected to the modular base structure.

In contrast, the modular base structure 2 for the 40ft ( 12.192mm ) shipping container (see figure 23) can include six cells w ith the middle cells being two half cells across the length but bisected by a middle longitudinal beam member 40. w ith four outer cells and two half middle colls each being equal in w idth to the width of the modular beam structure I . When modular beam structures I as shown in figure 23 are side abutting, then one modular beam structure in the middle can straddle the two middle abutting half cells to be connected to the modular base structure 2. In both of these modular base structures the longitudinal beam members 40 are continuous in length with the transverse cross beam members 41 extending between.

Height Variation of Shipping Containers - Shaving Corner Castings - Length and width variations of Shipping Containers

As shown in figure 34 the depth 52 of the modular base structure 2 can be used to allow for a difference in height of shipping containers 3 such as between short height shipping container 87 ie 8.6ft (2591 mm ) and a tall height shipping container 3 eg 9.6 ft (2896mm) containers which gives a difference of 2896-2591 305mm at the comer castings

The modular base structure 2 has a depth 52 (upper surface of upper casting 65 to lower surface of lower casting 65 ) as 275mm. When the modular base structure 2 is sitting on top of the top of a shipping container 3 ie casting to casting, there will be a gap G eg of 30mm which is created by the twist lock see figure 24. There is also an allowance made for the casting of the container to protrude upwardly beyond the roof the container as dimension 87 w hich can typically be about I Omm. This means that the depth 52 of the modular base structure 2 allows for the difference in height, making the top of the modular base structure 2 level with the top (the top being top of the castings or roof) of an abutting tall shipping container.

The standard outside length X width dimensions of a standard ISO shipping container are 1.12192mm X W2468mm. The centre to centre slot length X width dimensions are L l l S5mm X \V2259mm. For the outside length dimension of 12.192 we can accommodate five modular beam structure I side to side on one modular base structure on one shipping container. Therefore the length 21 of one modular beam structure I is set at 12.192 mm outside of comer casting and the length of one modular base structure 2 is set to 12.192mm which is subdivided by 5 spaces for 5 sides (side faces 9. 10) abutting modular beam structure I ie the width 21 (outside of casting to outside of casting) of each modular beam structure I will be 12. l 92mm/5~2438mm- 8mm for an allowance of uneven dimensions of the castings.

The length of the modular base structure 2 is sized to allow for most standard variations in container lengths and widths and for the dimensions and positions of the corner castings. One 40ft ( 12.192mm) length modular base structure 2 is sized to also receive two 20ft (6096mm) lengths of modular base structures 2. Additionally one 40ft ( 12.192mm) modular beam structure or two 20ft (6096mm) modular beam structures I can be used as five abutting structures along the length of one 40ft ( 12.192mm) or two 20ft (6096mm) modular base structures 2. on one 40ft ( 12.192mm) shipping container 3 or two 20ft (6096mm ) shipping containers .V

Some standard shaving of the sides of the casting of the shipping container can be combined with the allowance in si/e variations for the spacing of casting supports in the modular base structure 2. from outer surface of castings to outer surface of castings. Assembly

Λ method of assembly of a building structure utilizing the following components of a shipping container, a modular base structure 2 and or modular beam structure I of the present invention includes the steps of:

Arrange suitable wall supports in the form of shipping containers to form the walls of a proposed building structure being positioned to be spaced apart forming a roof spanning distance there between:

Place modular base structures onto the top of the shipping containers:

- Operate handle of the t\\ ist lock assembly of the shipping container to lock the modular base structure to the shipping container: - Positon an end portion of each modular beam structure onto the top of a base structure: - Operate twist lock assemblies in upper portion of the modular base structure to lock a lower casting of the modular beam structure to the modular base structure:

Repeat process for locking in as many modular beam structures to completely cover the modular base structure 2 and shipping container to form one side of the spanning distance between the shipping containers:

Repeat process for other side of span:

- l or spanning distances larger than the length of one module beam structure, bolt the ends of an opposing modular beam structure to another modular beam structure to finish at a central span position: - Bolt the ends of each opposing modular beam structure at a central span position to form a roof support:

- C ^' o\ er the roof support with any suitable covering

To form a building, the following standardized components include at least one shipping container 3 which can be used to form a wall of such a building structure whereby at least one modular beam structure is used to form at least part of a roof structure supported by a top of the walls or shipping containers.

The modular base structures 2 are used as a base for connecting underneath an end portion 86 (eg one box like cell 26) of at least one modular beam structure 1. The modular base structure 2 is located, connected or locked and supported on a roof 84 of the shipping container 20.

In a proposed building, the shipping containers 80 form the walls by hav ing the shipping containers SO positioned in parallel but spaced orientation from each other, forming a spanning distance 86 from side wall 81 to side wall 81 .

As shown in the figures each modular base structure 2 includes a standard set of cells 42 which space the transverse members 41 and non-comer castings 70, 71 appropriately to receive an end of each modular beam structure. As shown in the figures the end portion of each modular beam structure I is resting a complete width 51 of the modular base structure to cause a major proportion of the length to be cantilev er therefrom and spanning a half the spanning distance 86. An outside area of the modular base structure 2 is similar to an upper outside area of the shipping container to allow the interconnection between twist locks and apertures to connect and locate all of the modular base structure 2 on the lop of the shipping container.

The outside width 21 of the modular beam structure I is sized to match the space width 43 of each cell of the modular base structure 2 w hich operativcly allows the corner castings of the end of the end portion of one modular beam structure to inter-fit with the comer castings 65 and non-corner castings 70, 71 to allow several abutting modular beam structures to be supported to form at least part of a roof structure.

As shown in figure 5. the height 15a of the modular beam structure I is higher at one end than the other so that the higher end is located in the centre of a spanned distance between shipping containers 80 and the lower end of each modular beam structure I is located and connected to the modular base structure 2 or shipping container. To form the rest of the roof of the building a mirror image of one side is also erected.

Because the length 2 1 of the modular beam st met ure I is the set to be the same length as length of the modular base structure 2 and the shipping container 80 one can fit these inside a shipping container or because the height diminishes for the modular beam structure if one were to place two beam structures 2 in opposite ov erlapped orientations to lit the total height of the container or e\en allow easier transport.

VARIATIONS

Aspects of the present invention have been described by way of example only and it should be appreciated that modifications and additions may be made thereto without departing from the scope thereof. Though shipping container lengths of 20ft (60%mm) and 40ft ( 12.192mm) are mentioned in this specification, there are only examples and any other length or width or height dimensions are equally possible with the principle of the modular beam structure and modular base structures of the present im cntion to build a structure.

The modular beam structure can optionally be used as structural beams to span any suitable distances such as to form a bridge structure. Though angle, channel and I-beams or universal beams are used for the various elongate members, equally other cross sections or combinations of cross sections, are equally possible depending on structural and physical requirements. The particular shape of each beam or base structure can be varied by including more cells or more \ erticals or more cross members or bracing. The cross sections of the modular beam structures or modular base structures can also be varied to suit particular aesthetics or structural requirements.

The interconnected elongate members of the modular beam structure I can be connected or joined by a variety of methods such as by welding or bolting or any combination thereof. Furthermore the interconnected elongate members can be formed from any suitable material that is able to be joined or connected and provide appropriate structure strength and functionality as required. Extra castings or supports can be added to further enhance the structural integrity of the modular base structure with placing any loadings on the walls of the shipping container.

The wall support means includes any wall support comprising a frame including at least two posts 100 with comer castings 102 with twist lock assemblies 104 affixed to a top 106 of each post 100. The posts 100 can also optionally be interconnected together with cross bracing members 108 or be part of a wall frame 1 10.

DEFINITIONS

Throughout this specification the word "comprise" and \ariations of that word, such as "comprises" and "comprising", are not intended to exclude other additives, components, integers or steps. Throughout this specification the term "shipping container or transport containers" is intended to refer to the standardised shipping containers in the form of standardized reusable steel boxes, that are commonly referred to as "containers ^" , "intermodal containers", "freight containers". "ISO containers" or "hi-cube containers". These containers are used to store and mov e or transport materials and products in the global containerized intermodal freight transport system by road or by w ater.

These containers are sometimes referred to as "intermodal containers" since these containers can be moved from one mode of transport to another, i.e. from ship, to rail, to truck, without the need to unload and reload the contents of the containers. The length of these containers typically varies from 8 to 56 feet (2.438 to 17.069 m). with 20 feet and 40 feet long containers being most common. The heights vary from 8 feet {2.438 m) to 9 feet 6 inches (2.896 m), and the width is typically 8 feet (2.438 m).

'Wall support means ^' can be a term to describe any form of support that includes a structure including at least, corner castings suitable to support and adjustably connect with the corner castings and or tw ist lock assemblies of the modular base structure and modular beam structure. For example the wall support means can include structure that is able to support such as for example shipping containers or wall supports such as posts or w all framing.
