- FIGURE 13 is a section, to an enlarged scale, on the line 13-13 of Figure 2.
- Referring to the drawings, there is shown in Figures 1 and 2 a
building assembly 10 comprising four building units 11 - 14. Each building unit is rectangular in plan view having ashort end wall 15 and along side wall 16. - The
units building units unit 13 stacked on top of theunit 11 and theunit 14 stacked on top of theunit 12. - If desired more than two units may be provided in each storey and in each storey the units can be disposed in side by side relationship and/or end to end and/or end to side relationship to provide any desired combination.
- Alternatively, or in addition, the building assembly may comprise more than two storeys by stacking three units, one on top of the other.
- Each building module 11 - 14 in accordance with the invention comprises a
structural steel frame 20 as shown in Figures 3 and 4, preferably constructed from steel beams. Eachframe 20 comprises two upstanding sub-frames 21 a, 21 b, which lie in a vertical plane, each comprising respectivehorizontal roof beams horizontal 23b interconnected at their ends byfloor beams 23auprights floor joists 25, of which two, end, joists extend between thefloor beams uprights intermediate floor joists 25 are extended as shown in Figures 3 and 4. - The roof and
floor beams web 26, the roof andfloor beams lower flanges 27 andupper flanges 28. Theflanges - The
uprights - To enable the
beams uprights beams uprights angle bracket 29 bolted or welded to theweb 26 andside wall 31 of theuprights apertured plate 32 to which nuts 33 are welded (Figure 7). - The floor joists 25 are of channel shape in cross-section and each comprises a
vertical web 34 with horizontally directedflanges upper flange 35 of the intermediate joists having a downwardly directed lip at its free edge and both flanges of the end joists having inturned lips. - It will thus be seen that each sub-frame 21a, 21 b affords a rectangular aperture defined by the beams and
uprights - Lifting eyes may be removably secured to the tops of the
uprights - The units illustrated in Figures 3 and 4 include a
floor structure 41 comprising an upper sheet ofwood particle board 42 which rests at its lateral margins on theupper flanges 28 of thelower beams floor joists 25. - A foil faced film or
blanket 45 underdraws the floor joists 25 and is secured to the bottom flange of each joist by pneumatically driven nails and galvanised washers, or self drilling screws or other suitable fasteners. - To enable the whole structure to be supported on a lorry affording a bed narrower than the overall width of the building module, longitudinal
wooden bars 47 are secured in position beneath thejoists 25 inwardly of the ends of the module. - Each unit has a "roof" structure, which extends between and is secured to the
roof beams lower flanges 27 thereof. The roof structure of eachtop storey unit roof panel 50, and eachbottom unit 11, 12 (and intermediate unit, if present) aceiling panel 50a. - The
roof panel 50 comprises an inner skin 51 of plastic coated steel, anouter skin 52 also of plastic coated steel, a timber perimeter framework, part of which is shown at T, with the space between them being filled by an insulating infilling comprising a foamedplastic material 53, which in the present example is polyurethane foam. - The inner skin 51 comprises a plurality of planar plastic coated steel sheets, e.g. seven. In the present example, the plastic coating is that commonly known as a "low gloss Dolomite architectural polyester". The seven sheets are disposed side-by-side longitudinally of the roof panel and each sheet extends across the whole of the transverse extent of the roof panel. The adjacent edges of the sheets are crimped together.
- The
outer skin 52 comprises a plurality of profiled plastic-coated steel sheets, e.g. three, the plastic coating in the present example providing a white plastisol coating. - Each sheet, preferably, extends throughout the longitudinal extent of the roof panel and the sheets are disposed in side-by-side relation across the transverse extent of the roof panel with adjacent side portions in overlapping relationship so that the adjacent end two corrugations particularly overlap.
- A transversely extending reinforcing member 57 made of steel and of asymmetric channel configuration comprising a
web 58 disposed vertically so as to extend normal to the general plane of the inner andouter skins 51, 52; a lower limb of relatively short extent and an upper limb of relatively longer extent, in the present example approximately twice as long. The limbs are disposed so as to extend perpendicular to theweb 58. - The reinforcing member 51 is disposed at all desired positions and a desired number of reinforcing members may be provided. Each reinforcing member may be of different shape and/or different material than described above.
- At each end, the upper limb projects longitudinally outwardly of the
web part 58 and lower limb so as to overlie the longitudinally extending members of the frame T to be received in a rebate formed therein, so that the upper surface of the upper limb is flush with the upper surface of the longitudinally extending frame member. The lower limb is spaced above the skin 51 so that foam insulating material, in the present example polyurethane foam, enters the space between the undersurface of the lower limb and the upwardly facing surface of the skin, so as to avoid cold bridging between the inner and outer skins through the transverse reinforcing members 57. - The sheets of the
upper skin 52 stop short of the longitudinally extending members of the frame T and one limb of asteel trim strip 56 is arranged in overlapping relationship with the edge of thesheets 52 adjacent the associated frame member T with a sealant therebetween, whilst another limb of thestrip 56 is fastened to the roof beam. - The
roof panels 50 are positioned below thelower flanges 27 of the roof beams withspacers 59 therebetween. Thespacers 59 increase in height from one end of the roof panel to the other so that the roof panel is inclined downwardly as thespacers 59 increase in height relative to the roof beams so that water is discharged from the lower end of the roof panel. The angle of inclination may lie in the range of 1 in 120 to 1 in 60 depending upon the application of the building. - The connection between the roof panel and the
beam 16 comprises a plurality ofbolts 60 which pass through apertures formed in the lower skin 51, longitudinally extending frame members T, projecting part of the upper limb and theflange 27 of the roof beams 22a and 22b. - Thus, whilst the
vertical sub-frames rigid frame 20 are connected at the bottom by thejoists 25, no frame parts interconnect the sub-frames 21 a and 21 b at the top, the sub-frames being structurally interconnected solely by theroof panel 50. - It has been found, surprisingly, that the
roof panel 50 described above provides sufficient strength to hold the sub-frames 11 a and 11 b rigidly apart at their upper ends and thus serve a similar function as would metal frame cross-members. This is particularly due to the reinforcing members 57. - The
ceiling panel 50a extends between and is secured to the roof beams 22a and 22b therebelow by attachment to thelower flanges 27 thereof. - The
ceiling panel 50a comprises an inner skin 51 a of steel, an outer skin 52a of plywood, a timber perimeter framework, part of which is shown at Ta, with the space between them being filled by a foamed plastics material 53a, which in the present example is polyurethane foam. The timber framework Ta is bolted to theflanges 27 by bolts 60a. - Secured to the
frames 20 are endwall panel structures 70 and sidewall panel structures 80 although side wall panel structures are omitted from adjacent sub-frames 21 a, 21 b to provide an obstruction free interior for each storey. The adjacent sub-frames 21 a, 21 b ofadjacent units bolts 61. In addition themating flanges units bolts 62, a desired plurality ofbolts 62 being provided longitudinally of the beams. - If desired, further units may be bolted together in either end to end or side by side, or side to end relationship with appropriate end wall panel structures and/or side wall panel structures being omitted as desired to enable units to be linked together to provide a building construction of desired configuration.
- The end
wall panel structures 70 are secured to the inwardly facingsurface 31 ofuprights 24apanel structures 70 are received entirely within themetal frame 20. Cut-outs are provided at the bottom for the panels to accommodate the floor beams 23a - As shown in Figures 8 to 12, the end
wall panel structures 70 comprise anouter skin 71 of plastics coated steel and aninner skin 72 of plasterboard secured to aframework 73 oftimber members 73a to c and with foamed plastics insulation material or infilling 74 therebetween. - The outer skin comprises a plurality, in the present example, three,
rectangular metal sheets 75, each of which has opposededges 76 disposed to extend laterally in a horizontal direction, a horizontal edge of adjacent sheets being joined together along the length of said edges. The uppermost sheet is of the smallest height, the middle sheet the greatest height and the lowermost sheet the least height. This configuration is adopted so that the joint between the lowermost and middle sheet is at or below the bottom of any window or other opening with which the building unit may be provided. Similarly, the joint between the uppermost sheet and the middle sheet is at or above the level of the top of any such opening. This avoids the need to cross the or each of the above mentioned joints with a window or other opening. Of course, if desired, an opening may cross one or more of the joints, for example, in the case of a door, although, it is preferred to cross as few joints as possible. - As best shown in Figures 11 and 12 the horizontal edges of adjacent sheets are provided with
inturned flanges flange 77 providing a clip of generally channel shape having a pair oflimbs 77a, interconnected by abase 77b and the channel having a restrictedmouth 79 so as to exert frictional restraint on theother flange 78. If desired the sheets may be interconnected only at spaced positions along theiredges 76 and by other means than that described and illustrated in Figure 11 and 12. In Figure 11, the clip is shown provided on anupper sheet 75 whilst Figure 12 shows an alternative and preferred configuration where the clip is provided on the lower sheet. Otherwise the joint is the same in both Figures. - As best shown in Figures 10 and 11, the
internal framework 73 comprises a pair of spacedupright edge members 73a and a pair oflateral edge members 73b at the top and bottom of each panel structure and a pair of intermediate lateral members 73c extending between and positioned at or adjacent the joints of the outer skin. The intermediate horizontal members 73c are disposed adjacent one side of the joints so that the joint is embedded in theplastics infilling material 74. - The
inner skin 72 comprises a plurality of rectangular sheets each of which have opposed horizontally disposed edges, horizontal edges of adjacent sheets being juxtaposed with the inner sheets in overlapping relationship with the intermediate horizontal members 73c of the framework. - The shorter edges 76a of the
rectangular sheets 75 are upstanding in a vertical direction and disposed behind upright elements provided by theuprights surfaces 31 and so are protected from the elements. - The side
wall panel structures 80 are of similar construction to the endwall panel structures 70 and thevertical edges 81 of theirrectangular sheets 75 are disposed behind an inwardly facingsurface 82 of intermediateupright elements 83. Theintermediate uprights elements 83 may be provided for a aesthetic reasons, for example, to reflect the appearance of the shorter end wall of the building assembly and/or they may contribute to the overall structural strength of the frame and so comprise an upright of the structural frame, depending upon the size of the building and the way in which the intermediateupright elements 83 are attached to the building unit. In the present example, as shown in Figure 11, they are attached to theroof beams floor beams brackets - Each bracket comprises a square section tubular part 83c which is welded to an associated
intermediate element 83 and to a mountingplate 83d which is bolted by bolts 83e to theweb 26 of the associated roof beam or floor beam. - The
vertical edges 81 of the outer edges of the wall are disposed behind an additionalupright element 84 provided at the corner of the assembly and which provides a balanced aesthetic appearance so that the column pattern at the corners matches that at the junction between adjacent units where twouprights strip 85 is disposed between the transversely facingsurface 86 of the cornerupright element 84 and thevertical edge 81 of the panel structure to provide a protective seal with suitable sealing material therebetween. Thepanel structures Suitable sealant 89 is provided between the vertical edges of adjacent panels. In addition the timber frame at the vertical edges of thepanels 80 at the corner of the building is screwed to the mating timber frame at the vertical edge of thepanel 70. The additionalupright elements 84 may be wholly aesthetic or may contribute to the overall structural strength of the frame and so comprise an upright of the structural frame, depending upon the size of the building and the way in which they are attached to the building unit. In the present example, as shown in Figure 6, the corner uprights 84 are fastened to thewebs 26 of the roof andfloor beams angle brackets 91 welded to theuprights 84 and bolted to thewebs 26 bybolts 92. - An
intermediate panel 100 is disposed between the adjacent upper and lower edges of the endwall panel structures 70 of two stacked units (see Figure 5).Panel structure 100 comprises a metalouter skin 101 and aninner skin 102 of steel with aninfilling 103 of timber or mineral composite board therebetween. Theexternal surface 104 of theintermediate panel 100 lies in the same plane as theexternal surface 105 of thepanel structure 70. If desired, however, thesurfaces - In order to permit of the
surface 104 lying in the same plane as thesurfaces 105 eachpanel structure 70 of the upper and lower unit is provided with arebate rebate 110 is provided by forming the lower timber horizontal frame member with a reduced thickness lower edge portion into which theouter sheet 75 is bent to provide a surface of therebate 110. Therebate 111 is provided by a vertically extending limb 112 of anangle bracket 113 which is fastened by ascrew 114 to the uppertimber frame member 73 of thelowermost panel 70 and also to the peripheral frame member Ta of theceiling structure 50a. Again theouter metal sheet 75 is bent to lie against the limb 112 to provide a surface of therebate 111. - The
intermediate panel 100 has reduced thickness upper andlower edge portions 115 through which screws 116 are passed to secure the intermediate panel to thetimber frame member 73 and the limb 112 respectively. - Referring now to Figure 6, a similar
intermediate panel 100 is provided between the upper and lower horizontal edges of thepanel structures 80 on theside walls 16 of the units. The intermediate panels are as described with reference to Figure 5 and a rebate is formed in the lowermosthorizontal frame member 73 of theupper panel structure 80, also as described with reference to Figure 5. Thelower rebate 111 is provided by avertical limb 117 of a channel section bracket 118 which is fixed by ascrew 119 to the uppermosthorizontal frame member 80 and which has a vertically extendinglimb 120 parallel to and spaced from thelimb 117 which is fastened by ascrew 121 to the timber frame member Ta of theceiling 50a. Awater deflector member 122 is provided between theweb 26 and the upper edge of thelimb 117. - The
intermediate panel 100 corresponds in length to the associatedwall panel structures - Referring now to Figures 3 and 4, it will be seen that the
lowermost frame members 73 of thepanels 80 of the lowermost units are similarly provided with arebate 110 as are thelowermost frame members 73 of thepanel members 70 of the lowermost units.Skirt members 123 of similar construction at their upper ends to the intermediate panels are secured in therebates 110 by screws similar to thescrews 116 and trim the base of the lowermost module. - A
facia panel 124 extends along theside wall 16 to trim the top of the uppermost unit and is carried on the cornerupright elements 84 and its immediateupright elements 83. Asimilar facia panel 125 extends along the width of theend wall 15 to trim the uppermost units and are carried on theuprights - A
gutter 126 anddrain pipe 127 are positioned at the lower end of the roof panel. - Although not shown, the end and side wall panels, where provided, may be equipped with all necessary doors and windows, and the windows may be single or double glazed as required.
- All required internal fittings, including partition walls, carpeting or other floor covering, and appropriate mains services such as gas, electricity, water supply and sanitation may be provided so that the complete unit may be delivered to a prepared site, ready for use, subject only to securing adjacent units together where necessary and applying internal trim strips as necessary at the joints between adjacent units, and if required external trims.
- When two or more units are connected together in end to end configuration, the higher ends may be adjacent with suitable guttering being provided at the lower ends.
- If desired, a plurality of roof panels may be provided secured to and below the roof beams instead of a single roof panel.
- If desired, the structural frame may be of other configurations than that described hereinbefore. For example, it may comprise a rectangular floor sub-frame comprising a pair of spaced parallel floor beams connected together by transversely extending floor joists, a rectangular roof sub-frame comprising a pair of spaced parallel roof beams interconnected by a plurality of transversely extending roof joists, at least some of the transverse joists being connected to the roof beams intermediate the ends of the roof beams, and a plurality of upstanding, preferably generally vertical, columns extending between and interconnecting the floor and roof sub-frames. At least one floor panel may be supported on the floor joists. At least one roof panel may be supported on the roof joists.
- Although an assembly of four building units have been described above, a single building unit may be provided, or an assembly of any suitable combination of building units may be provided. Where a single building unit is provided a single storey assembly of building units, the or each unit may be provided with
skirt members 123 andfacia panels 124 as described herein before. - Although in the above example the units, their wall, roof and floor structures, and wall panel structures are all rectangular with the edges of the wall panel structure lying in vertical and horizontal planes, if desired the above described structures may be of other than rectangular shape. For example, the wall structures of a building unit may be inclined upwardly and inwardly or outwardly and the shorter upstanding walls may lie in a vertical plane but be inclined to the vertical; alternatively, or in addition, a wall panel structure may be of parallelogram shape with the longer side extending laterally but in a plane inclined to the horizontal whilst the shorter side may be upstanding in a vertical or near vertical direction. If desired the wall panel outer sheets may be of any other shape so long as the longer sides extend laterally, i.e. in a direction inclined to the vertical, and the shorter sides are upstanding, i.e. inclined to the horizontal.
