DETAILED DESCRIPTION OF THE INVENTION

Transporting a building module which includes a roof truss is subject to transport restrictions, especially as they relate to the height of a load. A collapsible roof truss of the invention enables transport of such a building module with the associated roof truss in a collapsed condition and thus of reduced height. The roof truss can then be erected once transport is complete. It is to be appreciated that a building module including the collapsible roof truss described below can be of a wide variety of sizes, not necessarily restricted to those which would comply with transport restrictions. For example, the building module could be of a size that requires specialised vehicles for transport. This does not derogate from the advantages associated with having a collapsible roof truss and the various ways of connecting the modules together.

2019100920 16 Aug 2019

Building structures assembled from building modules allows for the flexibility of manufacture at a site remote from the building site. This can have logistic and economic benefits.

In the drawings, reference numeral 10 generally indicates an embodiment of a collapsible roof truss according to a first aspect of the invention. Such a collapsible roof truss facilitates transport of a transportable building module which can include the roof truss 10. In figures 1 to 6, the roof truss 10 is shown in an erected condition. In figure 7, the roof truss is shown in a collapsed condition, with reduced height, suitable for storage and/or transport.

The roof truss 10 includes a ceiling beam 12 that spans the ceiling width of a building for which the roof truss 10 is intended. The ceiling beam 12 in this embodiment can include three sub-beams 14, 16, 18, with the sub- beam 16 interposed between the sub- beams 14, 18. A ceiling beam for use in a roof truss of the invention can include any practicable number of sub-beams. The ceiling beam 12 can be of any practicable material, including timber and steel. The ceiling beam 12 can have any practicable cross-sectional configuration. In this embodiment, the ceiling beam 12 is a steel Cchannel bar.

Outer struts 20, 26 and inner struts 22, 24 are attached to the ceiling beam 12 to span a ceiling space 28 of the building for which the roof truss is intended. Any practicable number of struts can be used to ensure the desired stability and strength of the roof truss. In this embodiment, the four struts 20, 22, 24, 26 are included in the roof truss 10.

Figure 3 shows an enlarged section of the roof truss 10 showing details of the struts 20, 22, 24, 26. Lower ends of the outer struts 20, 26 can be connected to inner ends of the ceiling sub-beams 14,18, respectively. This is achieved with respective connector plates 30, 36 fastened to the sub-beams 14, 18 and bolts 38, 44 through the connector plates 30, 36 and the lower ends of the struts 20, 26. Lower ends of the inner struts 22, 24 can be connected to outer ends of the ceiling sub-beam 16. This is achieved with respective connector plates 32, 34 fastened to the sub-beam 16 and bolts 40, 42 through the connector plates 32, 34 and the lower ends of the struts 22,24.

The struts 20, 22, 24, 26 are pivotable relative to the ceiling beam 12 through the bolts 38, 40, 42, 44, at respective pivots 46, 48, 50, 52.

The truss 10 also includes two rafters 54, 56, which extend from either end of the ceiling beam 12 to an apex 58 of the roof truss 10. The rafters 54, 56 are each

2019100920 16 Aug 2019 releasably fastened at an apex end to a connector plate 60 at the apex 58, by one or more bolts 62, 64.

Upper ends of the inner struts 22, 24 are releasably connected to the connector plate 60 by bolts 66, 68, respectively, through the connector plate 60 and the inner struts 22, 24. The inner struts 22, 24 are pivotable relative to the rafters 54, 56 through the bolts 66, 68 at respective pivots 70, 72. The inner struts 22, 24 are thus angled inwardly towards the apex 58. The angle can be selected to be similar to that of struts of a conventional, similarly sized truss.

An upper end of each outer strut 20, 26 is releasably connected to the respective rafters 54, 56. This is achieved with respective connector plates 78, 80 fastened to the respective rafters 54, 56 and bolts 74, 76 through the connector plates 78, 80 and the upper ends of the outer struts 20, 26, respectively. Thus, the outer struts 20, 26 are pivotable relative to the rafters 54, 56 through the bolts 74, 76 at respective pivots 82, 84. The struts 20, 26 can be perpendicular to the respective rafters 54, 56 or can be at an angle to the rafters, which would be suitable for a conventional, similarly sized, truss.

The struts 20, 22, 24, 26 are oriented relative to the ceiling beam 12 and the rafters 54, 56, in a conventional manner, or in a suitable manner, when the truss 10 is in the erected condition.

The struts 20, 22, 24, 26 can be of any practicable material, such as timber or steel. The struts 20, 22, 24, 26 can have any practicable cross-sectional configuration. In this embodiment, the struts 20, 22, 24, 26 are each a steel C-channel bar.

Figures 4 and 5 show rear and front views, respectively, of an enlarged eave end portion of the rafter 54. This end of the rafter 54 is pivotably fastened to the ceiling beam 12. This can be effected by pivotable fastening of this end of the rafter 54 to an eave member 86 with a bolt 88, to provide a pivot 90. The eave member 86 can in turn be fastened to the ceiling beam 12 with an eave bracket 92. The roof truss 10 can include a further eave bracket 94 and a beam bracket 96, which are positioned to secure a channel section, not shown here and discussed below.

Referring to figure 6, the second rafter 56 pivots in a similar manner at an opposite end of the ceiling beam 12, about a pivot 98.

The rafters 54, 56 can have any practicable cross-sectional configuration. In this embodiment, the rafters 54, 56 are each a steel C-channel bar.

Referring to figures 1, 3 and 7, the roof truss 10 can be reversibly changed from an erected condition (figures 1 and 3) to a collapsed condition (figure 7). This can be

2019100920 16 Aug 2019 effected in a number of ways but is illustrated in this embodiment in the following manner. Starting with the roof truss 10 in figure 1 in an erected condition and referring to a more detailed view of a central portion of the truss 10 in figure 3, the bolt 68 is removed and the inner strut 24 pivoted downwardly to lie on the sub-beam 16. The bolt 76 is removed and the strut 26 is pivoted downwardly to lie on the sub-beam 18. The bolts 64 are removed and the rafter 56 is pivoted downwardly to lie on the struts 26, 24. The bolt 74 is removed and the strut 20 is pivoted downwardly to lie on the sub-beam 14. The bolt 40 is removed and the strut 22 is pivoted upwardly to accommodate downward pivoting of the rafter 54, which then rests on the strut 22 that is interposed between the rafter 54 and the rafter 56.

In such a collapsed condition, the roof truss 10 has a reduced height profile and can more readily comply with transport regulations.

The collapsible roof truss 10 can be included in a transportable building module of the invention. Figures 8 to 12 show such a building module 100, which includes a plurality of the roof trusses 10 in a roof assembly 102. In this embodiment of a building module of the invention, the roof assembly 102 includes outer joists 104, 106 and inner joists 108, 110, oriented perpendicular to the ceiling beams 12 of the roof trusses 10. The inner joist 108 is positioned between sub-beams 14 and 16, and the inner joist 110 is positioned between the sub-beams 16 and 18.

The roof assembly 102 can also include one or more beams such as channel sections 118, 120 for supporting the roof trusses 10. In this example, the channel sections 118, 120 are each positioned between the eave members 86 and the ceiling beams 12. Figure 9 shows an enlarged front, upper right section of the building module 100, including the channel section 120. Figure 10 shows a rear view of the section shown in figure 9. Referring to figures 9 and 10, the channel section 120 is secured to the ceiling beams 12 by the beam brackets 96 and to the eave members 86 by the eave brackets 94, which are described above.

The channel sections 118, 120 can enable lifting machinery, for example a crane, to engage with the building module 100, and lift, move or position same.

The channel sections can be of any practicable material, such as timber or steel. The channel sections 118, 120 can have any practicable cross-sectional configuration. In this embodiment, the channel sections 118, 120 are each a steel C-channel bar.

As can be seen in figures 8 and 11, the roof assembly 102 is arranged on a wall assembly 124, which is arranged on a floor assembly 126.

2019100920 16 Aug 2019

The wall assembly 124 includes multiple studs 128, which extend peripherally from the floor assembly 126 to the roof assembly 102 to support the roof assembly 102. The studs 128 can be secured to the roof assembly 102 and the floor assembly 126 by any practicable means. The number, configuration and distribution of studs is variable, and depends on the intended use of the associated building module. For example, the studs define potential solid wall portions, windows, doorways, and the like. The wall assembly can include crossbeams 130 between the studs 128. The crossbeams 130 can be horizontal or angled.

The studs 128 can be of any practicable material, and cross-sectional configuration.

The floor assembly 126 can include multiple floor beams 132 with end floor joists 134, 136 and floor joists 138, 140, interposed between the joists 134, 136, perpendicular to the floor beams 132. The wall assembly 124 can be secured to the floor assembly 126 by securing the studs 128 of the wall assembly 124 to the end floor joists 134, 136 by any practicable means.

In order to facilitate use of two or more building modules of the invention in a building structure, the floor assembly of each building module includes a first part of a locating arrangement 142 positioned on a first side of the floor assembly 126 and a second part positioned on an opposite, second side of the floor assembly 126. More particularly, the first part is positioned on one end of each joist 134, 136 of each building module. The second part of the locating arrangement 142 is on an opposite end of each joist 134, 136. Figures 13 to 15 show details of a view from below of the locating arrangement 142. Figure 16 shows the same locating arrangement from above. In these drawings reference numerals 134.1 and 134.2 and associated sub-numbering is used for clarity only in order to distinguish identical joists 134 from each other.

The first part of the locating arrangement 142 includes an end plate 143 mounted on an end of the joist 134.1 and on an adjacent floor beam 132.1. Aprojection 144 extends from the end plate 143 in line with the joist 134.1. The second part of the locating arrangement 142 includes an end plate 145 mounted on an end of the joint 134.2 and on an adjacent floor beam 132.2. It will be appreciated that the end plate 145 is mounted on an opposite end of the joist 134 to the end plate 143. The end plate 145 defines a locating recess 150 that opens downwardly. The recess 150 tapers inwardly and upwardly from its opening.

In use, and with reference to figure 12, a building module 146.1 is initially laid on a suitable substrate, such as a slab of concrete. The building module 146.1 includes the

2019100920 16 Aug 2019 joist 134.1. Subsequently, a building module 146.2, including the joist 134.2, is lowered and brought adjacent to the module 146.1. The module 148 is lowered so that the projection 144 is received in the recess 150. The inward taper of the recess 150, described above, serves to facilitate guidance of the projection 144 into the recess 150 as the module 148 is lowered.

A spacer 152 is interposed between the end plates 143, 145. Thus, the spacer 152 is interposed between the first and second sides of the respective building modules 146.1, 146.2. The spacer 152 is dimensioned so that when the modules 146.1 and 146.2 are connected together, the spacer 152 serves to maintain an appropriate spacing between the end plates 143, 145 and thus the modules 146.1, 146.2.

The end plates 143, 145 are connected together with two bolts 158, 160 that extend through the end plates 143, 145. In use, once the module 146.2 has been lowered into position relative to the module 146.1, with the projection 144 received in the recess 150, the bolts 158, 160, together with appropriate fasteners, such as nuts, can be tightened to draw the end plates 143, 145 together with the spacer 152 interposed between the end plates 143, 145.

It will thus be appreciated that the locating arrangement 142 can serve to properly locate the modules 146, 148 relative to each other on the substrate.

Referring to figures 13 to 16, brackets 154, 156 extend from respective ends of the floor joist 134. The brackets 154, 156 include openings so that they can be used to fasten the joist 134 to the substrate, for example in the form of a concrete slab. This can take place once the modules 146.1, 146.2 have been located relative to each other, as described above.

Building structures of many different configurations can be assembled from building modules of the invention. For example, figure 17 shows a framework 162 for a complete modular home. The framework 162 can be assembled from five building modules 164, 166, 168, 170, 172, as described above, shown in separated top view (figure 18) and separated side view (figure 19) of the framework. Each building module 164, 166, 168, 170, 172 includes a roof assembly 174, 176, 178, 180, 182 including the collapsible roof truss 10, a wall assembly 184, 186, 188, 190, 192, a floor assembly 194, 196, 198, 200, 202, and locating arrangement 204, 206, 208, 210. These components and assemblies are described above.

The modules 164, 166, 168, 170, 172 can be manufactured offsite, each building module including the collapsible roof truss. The collapsible truss of each building module ίο

2019100920 16 Aug 2019 can be placed in the collapsed condition, as described above, for transport and/or storage. The building modules 164, 166, 168, 170, 172 can be transported to the building site, and the first building module 164 can be lifted from the transport vehicle using the channel section 118, 120 of that module, and placed in position on a concrete slab, for instance. The building modules are connected together as described above with reference to the building modules 146.1, 146.2.

The roof trusses of each roof assembly 174, 176, 178, 180, 182 can then be erected to result in the desired building structure.

Any building module, roof truss or combination thereof according to the invention can be lifted, moved and positioned by means of a crane or the like with a suitable connector, such as a spreader assembly releasably connected to one of more lifting lugs on the module or truss. The lifting lugs can be positioned at any practicable position on any portion of the module or truss. Figure 20 shows a lifting lug 220 positioned on an outer joist 222 of a building module 224 (partially represented) connected to a roof truss 226. Figure 21 shows a lifting lug 228, 230 at each end of an assembled side panel 232 of a module according to the invention.

Referring to figures 22, 23 and 24, reference numeral 234 generally indicates a spreader assembly for lifting and manoeuvring the building module described herein.

The spreader assembly 234 can include one or more upper spreader beams 236. In this embodiment, the spreader assembly 234 includes two upper spreader beams

236.1.236.2. Each upper spreader beam 236 includes one or more beam modules 238. In this example, each upper spreader beam 236 includes three substantially identical beam modules 238.1 to 238.3. The beam module 238.2 is interposed between the beam modules 238.1,238.3. The beam modules 238 are connected, end to end, in a detachable manner. Thus, an overall length of the spreader beam 236 can be varied depending on the number of beam modules 238 connected together. Two chain or cable connectors, in the form of clevis fasteners 240 are connected to the beam modules

238.1.238.3, respectively, so that the spreader beam 236 can be connected to a crane, or the like. Thus, in this example, pairs of clevis fasteners 240.1,240.2 are located on respective sides of a lifting zone 242. As can be seen in figures 23 and 24, the spreader assembly 234 can include two upper spreader bars 244.1,244.2 connected to respective pairs of clevis fasteners 240.1,240.2. The clevis fasteners 240 are connected to the crane, or the like, with suitable rigging 246, such as cables or chains.

2019100920 16 Aug 2019

Each upper spreader beam module 238 has a flange 248 on each end of a body 250. The flange 248 is configured so that the flanges 248 of adjacent modules 238 can be bolted together to fasten the modules 238 together.

The body 250 defines a series of holes or openings 252 along a lower edge of the body 250. The openings 252 are dimensioned so that a suitable connector can be engaged with the body 250. For example, a suitable connector may be used to connect the body 250 with the lifting lugs 220, 228, 230. A length of the upper spreader beams 236 can be varied, depending on the number of modules 238 used to accommodate differently spaced lifting lugs 220, 228, 230. Further accommodation can be achieved by the selection of appropriate openings 252 four engagement with said suitable connector. Given that there are two upper spreader beams 236.1,236.2, it is possible for lifting to occur on each side of a building module, for the purposes of stability.

The suitable connector can be a shackle or a combination of shackles 254. For example, the suitable connector can be two shackles 254, for example, D-shackles, connected to each other. In that case, one of the shackles 254 will be connected to the appropriate beam module 238 while the other shackle 254 will be connected to the lifting lug 220, 228, 230.

The spreader assembly 234 can include a number of lower spreader beams 256 that are connectable to the upper spreader beams 236, generally orthogonal to the upper spreader beams 236.

The spreader assembly 234 includes four of the lower spreader beams 256.1, 256.2, 256.3 and 256.4. Each of the lower spreader beams 256 includes a flange 258 on each end of a body 260. The flange 258 is configured so that the flanges 258 of adjacent beams 256, if desired, can be bolted together to provide a modular lower spreader beam 256 having a variable length.

Two lifting lugs 262 are symmetrically located on the body 260 about an operatively vertical centreline. Each lifting lug 262 can be connected to the body 250 of one of the beam modules 238 with a suitable connector. For example, the suitable connector can be a shackle or a combination of shackles 264, for example, D-shackles, connected to each other.

The body 260 defines a series of openings 266 along a lower edge of the body 260. As with the openings 252, the openings 266 allow the lower spreader beams 256 to be connected to the lifting lugs 220, 228, 230 of the module. Thus, the spreader

2019100920 16 Aug 2019 assembly 234 can be used to engage the crane, or the like, with the building module for lifting the building module.

The number of lower spreader beams 256 can be selected to accommodate the location of the lifting lugs 220, 228, 230, depending on the configuration of the building module to be lifted. Still further, the respective positions of the spreader beams 256 can be adjusted or varied to accommodate the number and location of the lifting lugs 220, 228, 230. Further accommodation is achieved by appropriate selection of the openings 266 for the connectors.

The appended claims are to be considered as incorporated into the above description.
