Definitions

  • the present invention relates to a blast-resistant partition.
  • a partition may be used as a wall, floor, or ceiling to provide protection against a blast.
  • Blast-resistant and fire-resistant partitions are required in the off-shore oil and gas industry, for instance for the construction of a accommodation modules, work rooms, office accommodation, separating walls, and equipment and storage rooms. Such partitions may also be used in on ⁇ shore applications, for instance in the chemical industry. Partitions of this type are required to provide protection for personnel in environments where there is risk of explosions.
  • a known method of making partitions for resisting blast and fire involves welding or bolting solid material, such as steel plate, to a substantial steel sub-frame. The cavities between the sheets may then be filled with insulation to the required fire standard.
  • Such a partition has to be designed to withstand a blast using conventional methods of calculation such that the steel supports are capable of withstanding a "dynamic" loading. When a blast occurs, such a conventional wall is designed to withstand the blast with minimal movement within the structure.
  • the partition performs in a "dynamic” manner i.e. the structure responds to the load after the time period of the blast has taken place. The load applied to the main steel work is therefore approximately twice that which would be applied under a "static" load.
  • EP-A-425281 discloses a wall structure in which panels made of fire resistant material sandwiched between outer metal surface sheets are clamped to supports at their edges. The supports are in turn attached to or form a main structure so that the supports are substantially rigid.
  • Such partitions provide fire-resistant properties but are of limited use in resisting blast. In particular, a blast causes the panels to "bow" away from the source of the blast while transmitting relatively small dynamic loads to the supports.
  • the blast-resistance of such partitions is limited by the need for the panels to be retained in place by the supports and this places severe requirements on the construction of the panels if relatively large blasts are to be resisted.
  • a blast- resistant partition comprising a first panel having a first edge with a dove-tailed cross-section, first and second edge supports for supporting the first panel, and clamping means for clamping the first and second edge supports together such that first and second surfaces of the first and second edge supports, respectively, define therebetween a slot having at least a portion having a tapered cross-section for receiving the first edge of the first panel so as to fix the first panel to the first and second supports, at least one of the first and second surfaces being resiliently movable to permit relative movement between the first panel and the first and second supports and to exert a restoring force on the first edge urging the first edge to return into the slot.
  • dove tail is used in a broad sense to encompass cross-sections which fan out from a region of attachment, even if the cross-section then changes, for example, by changing to a parallel sided portion, as shown in Figure 1 1 of the accompanying drawings.
  • a second panel having a second edge with a dove-tailed cross-section
  • the first and second edge supports have third and fourth surfaces, respectively, defining therebetween a further slot having at least a portion having a tapered cross-section for receiving the second edge of the second panel so as to fix the second panel to the first and second supports, at least one of the third and fourth surfaces being resiliently movable to permit relative movement between the second panel and the first and second supports and to exert a restoring force on the second edge urging the second edge to return into the further slot.
  • first and second edge supports are substantially identical to each other.
  • the clamping means may comprise a plurality of clamping arrangements, each of which comprises a nut and bolt and a spacer for spacing apart the first and second edge supports.
  • Each of the first and second edge supports preferably has a U-shaped channel with limbs directed towards the other edge support. Fire- resistant material may be held between the U-channels of the first and second edge supports.
  • Each limb of the U-channel may be provided with a flange defining one of the first to fourth surfaces and forming an obtuse angle with the limb.
  • a further flange may extend from the edge of the flange remote from the limb and parallel to the limb, the further flange abutting against an edge shoulder of the first or second panel.
  • Each of the first and second edge supports may comprise an open section having an outwardly facing open side. The open side may be covered by a closure member attached to the edge support so as to permit relative movement between the edges defining the open side and the closure member.
  • each of the first and second edge supports has a U-shaped channel with limbs directed away from the other edge support.
  • Each limb of the U-channel may extend to form a first flange extending substantially parallel to a base of the U-channel.
  • the first flange may have an end which is folded over and extends into a second flange which is parallel to an edge shoulder of the first or second panel.
  • the second flange may extend into a third flange which forms acute angle with the second flange and which defines one of the first to fourth surfaces.
  • the third flange may extend into an end portion which extends parallel to the second flange and which forms an obtuse angle with the third flange.
  • the end portions of the first edge support may be fixed, for instance by welding, to a U-shaped spacer for cooperating with the clamping means.
  • each of the first and second edge supports has a generally "U" shaped channel with limbs directed towards the other edge support.
  • a first flange extends perpendicularly from each limb and a second flange extends from the edge of the first flange remote from the "U" shaped channel at an obtuse angle to the first flange.
  • Each pair of the first and second flanges cooperate to define one of the first to fourth surfaces.
  • a third flange extends from each second flange at the edge thereof remote from the "U" shaped channel and substantially perpendicularly to the first flange so that, in use, the third flange abuts an edge shoulder of the associated panel.
  • each of the first and second edge supports is provided with attachment means for a cover plate.
  • the attachment means may be an inclined wall formed in the vicinity of an outward facing edge of each of the third flanges and the cover plate may have edges bent over so as to embrace the inclined walls.
  • a shoulder, parallel to the first flange, may be provided at the outward facing edge of the third flange.
  • each of the first and second edge supports is provided with a respective closure which comprises a substantially "U" shaped member having a fourth flange extending perpendicularly from each limb of the "U".
  • each one of the edge supports and the respective closure member are arranged in a back-to-back fashion, and the fourth flanges extend towards and rest against the shoulders formed at the edges of the third flanges.
  • the fourth flanges of the closure members cooperate with the first to third flanges and the limbs of the "U" shaped members to form ducts which may be filled with fire resistant material.
  • the first edge support has at least one hole formed in each of the first flanges thereof.
  • Advantageously holes are formed at corresponding positions in the fourth flange of the closure member associated with the first edge support.
  • a passage extends between each pair of holes in the first and fourth members such that a fastener can extend between the holes.
  • Aligned holes are also formed in the "U" shaped portions of the first and second edge supports and the associated closures such that fasteners, such as bolts, can extend between the first and second edge supports to secure them together such that the edge supports grip the or each panel.
  • the loading applied by a blast may thus be treated as a static load, which is generally approximately half of the load experienced under dynamic conditions.
  • Such a partition may also provide fire resistance.
  • the partition may be constructed of light weight materials and the edge sections may hold external cladding of the panels in position so as to prevent the passage of smoke and flame from one side of the partition to the other. Further, such partitions are capable of withstanding blast and of remaining integrally sound after such a blast so as to withstand a fire that might follow.
  • the edge supports may be designed to deflect as a result of a blast so as to share the load and limit the dynamic loading applied to a supporting structure.
  • Figure 1 shows a cross-section of a partition constituting an embodiment of the present invention
  • Figure 2 is a front view of a cover sheet of the embodiment of Figure 1;
  • Figures 3 to 5 show cross-sections of components of the partition shown in Figure 1 ;

  • the blast and fire-resistant partition shown in the accompanying drawings comprises a plurality of composite panels joined together at their edges by jointing arrangements to form walls and/or ceilings and/or floors.
  • the drawings show two such composite panels 1 and 2 joined together by a jointing arrangement 3.
  • Each of the composite panels 1 and 2 comprises a lamination of sheet steel faces 4 to 7 containing a fire- resistant core material 8 and 9.
  • Each of the sheet steel faces 4 to 7 is bent, for instance at 10, 11 , and 12 of the face 4, so as to form an end shoulder 13, which extends inwardly and perpendicularly with respect to the main face of the panel 1 , and an inclined section 14, which forms an acute angle with the shoulder 13.
  • Each of the panels thus has dove ⁇ tailed edges such as 15 at both ends thereof.
  • the shoulders 13 act to facilitate handling of the panels and to provide some protection for the core material 8.
  • the jointing arrangement 3 comprises two identical parts 20 and 21 clamped together by a nut 22 and bolt 23 and spaced apart by a tubular spacer 24.
  • Each of the parts 20 and 21 comprises a sheet steel section 25 and 26, for instance formed into shape by rolling.
  • the section 25 will be described, the section 26 being substantially identical thereto.
  • the section 25 comprises a U-shaped channel with limbs 27 and 28 extending inwardly from the base of the channel.
  • Inclined flanges 29 and 30 extend from the ends of the limbs 27 and 28 at an obtuse angle thereto.
  • Shoulders 31 and 32 extend from the ends of the flanges 29 and 30, respectively, parallel to the limbs 27 and 28.
  • the edges of the shoulders 31 and 32 extend via three right angle bends of alternating directions to form edges 33 and 34.
  • the edges 33 and 34 define an outwardly facing opening of the section 25.
  • the inwardly facing U- shaped channels of the sections 25 and 26 hold therebetween fire- resistant and heat-insulating material 35.
  • a cover 36 is provided for closing the opening of the section 25 and defining an internal cavity which is filled with fire-resisting and heat insulating material 37.
  • the cover 36 comprises a steel plate fixed to the edges 33 and 34 of the section 25 by screws or bolts 38 and 39 passing through elongate holes 40, as shown in Figure 2, in the cover 36.
  • the cover 36 also has holes 41 providing access to the nut 22 and the bolt 23.
  • the cover 36 is pre-assembled with the section 25 by means of the screws or bolts 38 and 39 with the material 37 filling the interior.
  • These assemblies forming the parts 20, 21 may be transported to the installation site in this condition.
  • the assemblies may be fixed together by means of the nuts 22, bolts 23, and spacers 24 with the material 35 installed therebetween and held in place by the U-shaped channels for transportation to the installation site.
  • the materials 35 and 37 which may be relatively delicate, are protected during transportation and installation.
  • edges of the cover 36 are bent at 45 so as to fit over the section 25 and provide an accurate outer width to the cover 36.
  • a decorative cover 46 for instance made of metal or any other suitable material, has bent edges 47 which clip over the edges 45 of the cover 36 so as to provide a finished surface to the jointing arrangement 3.
  • Figure 7 shows an arrangement for supporting the partition on structural member 55, for instance of an off-shore platform.
  • the bolt 23 at such fixing locations is extended through clearance holes in the cover 36 and the decorative cover 46 so as to pass through a clearance hole in the member 55.
  • the partition is spaced from the member 55 by an engineering spring 56.
  • the panels 1 and 2 are deflected by the blast and the dove-tailed ends 15 tend to bend and withdraw from the tapered slot formed by the flanges 30 of the sections 25 and 26.
  • a substantial part of the blast is therefore used to overcome the inertia of the partition.
  • the resilience of the sections 25 and 26, particularly in the region of the flanges 30, provides a restoring force which tends to urge the dove-tailed ends 15 back into the tapered slots following the blast.
  • the sections 25 and 26 may be designed to bend so as to overcome the energy of the blast and thus increase the blast-resistance of the partition.
  • the partition can therefore flex in response to a blast and, even if some permanent deformation of the panels and the jointing arrangements occurs, the partition remains intact and continues to provide fire-resistance so as to prevent or delay the passage of fire and heat from one side of the partition to the other. Deflection of the partition compresses the spring 56 so that the load transferred to the member 55 as a result of the blast is reduced. Deformation of the member up to its plastic limit further provides blast-resistance, so that the partition and its fixing arrangement to the member 55 share the dynamic loading caused by the blast and very high resistance to blast is provided by the whole arrangement.
  • the partition itself is relatively light and inexpensive and retains its fire-retardant integrity for relatively large blasts.
  • Figure 8 illustrates the deflection 21 in millimetres (left hand vertical axis) against time as a result of a typical blast 22 (right hand vertical axis). Because of the relatively light-weight construction of the partition and the resilience oi the panels and the jointing arrangement, the amount of deflection during the blast follows the applied load caused by the blast almost simultaneously. Following the blast when the applied load has ceased, there is some residual deflection resulting from deflection beyond the plastic limit of parts of the partition. However, the fire- resistant integrity of the partition is not damaged so that the partition resists the passage of fire following the blast.
  • the resilience of the parts of the partition and the connections therebetween share the dynamic loads imposed on the partition and on the supporting structure so that the imposed loads may be considered as "static" loads rather than “dynamic” loads.
  • the relatively lightweight construction allows deflection to follow the blast profile quickly which, again, reduces the applied loads experienced by each of the parts.
  • the clamping arrangement ensures that following relatively large blasts, the ability of the partition to prevent the passage of smoke and flames is retained so as to provide a high degree of fire resistance following such a blast.
  • the partition may be made with accurate manufacturing tolerances.
  • the cover 36 has edges 45 which can be accurately folded in terms of tolerances to provide an accurately manufactured width. This allows the decorative cover 46 to be easily manufactured and to fit in place easily and reliably.
  • the cover 36 tends to expand towards the fire.
  • the fixing via the elongate holes 40 permits such expansion without applying substantial stress to the sections 25 and 26.
  • the insulation material 37 provides protection from heat for the clamping arrangement comprising the nut 22, the bolt 23, and the spacer 24. Thus, there is no direct passage of heat by means of conduction or radiation from the decorative cover 46 on one side to that on the other side.
  • the spacer 24 shown in the drawings is tubular and may be used to provide fire-resistance and blast-resistance up to a certain limit. In order to provide protection against heavier blasts, the spacer 24 may be replaced by a square or rectangular section spacer which fits tightly into the facing U-shaped channels of the sections 25 and 26.
  • Figure 9 shows a partition constituting another embodiment of the invention.
  • the composite panels 1 and 2 differ from those shown in Figures 1 to 7 in that they have stepped shoulders adjacent the dove ⁇ tailed edges 15. The four stepped shoulders at the two panel edges are identical and only one will be described.
  • the sheet steel face 4 is bent at right angles at 61, 62, and 63 so as to provide a recess containing a gasket 64.
  • the steel face 4 provides a shoulder 13 corresponding to that shown in Figures 1 to 7.
  • the face 4 is further bent so as to provide an inclined section 14 corresponding to that shown in Figures 1 to 7.
  • the edge 65 of the face 4 is then bent over as shown in Figures 1 to 7 so as to provide a flange whose sole purpose is to protect the edges of the material 8 prior to assembly of the partition.
  • the parts 20 and 21 comprise identical sheet steel sections 25 and 26, only the section 25 being described.
  • the section 25 comprises a U-channel with limbs 27 and 28 facing outwardly. The edges of the limbs 27 and 28 extend into flanges 66 and 67 which are folded over at 68 and 69.
  • the section 25 further comprises shoulders 31 and 32 which extend into inclined flanges 29 and 30 ending in edge portions 70 and 71 extending towards the flanges 66 and 67.
  • the section 26 differs from the section 25 in that its edge portions 70 and 71 are welded to a spacer 72 of U-shaped cross-section.
  • the bolts 23 pass through holes in the section 25 and the base of the U-shaped spacer 72 so that the sections 25 and 26 are fixed together and separated by the tubular spacers 24.
  • Each shoulder 13 is spaced from the adjacent shoulder 31 , 32 by a gap which contains a fire seal 73.
  • the various cavities within and between the sections 25 and 26 are filled with fire-resisting and heat insulating material, for instance as shown at 74 and 75 and comprising calcium silicate board.
  • the U-channels in the sections 25 and 26 contain cover strips 76 and 77 so as to provide a partition having substantially flush inner and outer surfaces.
  • the partition shown in Figure 9 operates in essentially the same way as that shown in Figures 1 to 8 in response to blast.
  • the section 25 or 26 may be directly exposed to the fire.
  • the flanges 66 and 67 attempt to expand and the presence of the U-section with the limbs 27 and 28 provides stiffness in the vertical plane, thus allowing a deliberate expansion in the horizontal plane.
  • the flanges 66 and 67 thus move and create curves such that the shoulders 32 are urged towards the shoulders 13.
  • This general movement causes the edge portions 70 and 71 to move towards the flanges 66 and 67, thus urging the U-spacer 72 towards the flanges 66 and 67.
  • the sections 25 and 26 are thus urged towards each other via the nut 22 and the bolt 23 so that the dove-tailed ends 15 are urged inwardly of the jointing arrangement 3.
  • the structural integrity of the partition is thus maintained in the presence of a fire.
  • the gasket 64 and the seal 73 seal the panels 1 and 2 to the jointing arrangement 3 so as to prevent the passage of fire, heat, and smoke from one side of the partition to the other.
  • the partition shown in Figure 10 differs from that shown in Figure 9 in that the parts 20 and 21 comprise substantially identical sheet steel sections 25 and 26 which differ in profile from the sections 25 and 26 shown in Figure 9.
  • the section 25 comprises a substantially flat base 80 provided with countersunk holes for countersunk-headed bolts 23.
  • the base 80 extends via inclined portions 81 and 82 so as to form a channel section, into flanges 83 and 84 which are bent over twice at right angles to provide return flanges 85 and 86.
  • the shoulders 31 and 32 extend from the ends of the return flanges 86 and 85, respectively.
  • the spacer 72 shown in Figure 10 differs from that shown in Figure 9 in that the ends of the limbs are bent over as shown at 87 so as to form narrow channels.
  • the edge portions 70 and 71 of the section 26 are received in the channels, for instance as an interference fit, and may additionally be welded thereto.
  • the performance of the sections 25 and 26 in Figure 10 is substantially the same of the sections 25 and 26 in Figure 9, except in respect of the flanges 83 and 84 and the return flanges 85 and 86.
  • the folded-over flanges 66 and 67 in the embodiment of Figure 9 effectively provide a double thickness of metal which move under fire conditions at a rate which is different to the single thickness of metal in the embodiment of Figure 10. Otherwise, the sections 25 and 26 shown in Figure 10 have the advantage that the shapes are easier to manufacture.
  • the panels 1 and 2 are of a similar construction to those shown in Figure 9.
  • the sheet steel face 4 is bent at right angles at 61 , 62, and 63 so as to provide a recess which locates a gasket 100 to provide a weather seal.
  • the parts 20 and 21 comprise similar sheet steel sections 25 and 26, only the section 25 being described.
  • the section 25 comprises a sheet steel member folded so as to form a U-channel with limbs 27 and 28 extending towards the part 21.
  • a fold is formed at the top of each of the limbs so as to define first flanges 102 and 104.
  • the flanges 102 and 104 are bent at 106 and 108 to define second flanges 1 10 and 1 12.
  • the second flanges are folded over at 1 14 and 1 16 to define shoulders 31 and 32 which are further folded to define second shoulders 1 18 and 120 which are parallel to the first flanges 102 and 104.
  • the sheet steel section 25 is further folded at the ends of the second shoulders to provide tapered sections 122 and 124 to locate the gaskets 100.
  • a cover plate 46 having bent edges 47 can be engaged in a snap fit arrangement with the outer edges of the tapered sections to provide a finishing surface for the jointing arrangement 3.
  • the panels are identical to one another with only the panel 1 being described herein.
  • the panel has a shoulder 13 which is arranged to face the shoulder 32.
  • the face of the panel 4 is folded at 1 1 so as to form an inclined section 14 which makes an acute angle with the shoulder 13, thereby providing a dove-tailed edge.
  • the face 4 is further folded at 130 so as to define a surface 132 which is substantially perpendicular to the shoulder 13.
  • the panel has a modified dove ⁇ tail cross-section.
  • a closure 140 comprises a sheet steel member which is folded so as to define a U-shaped channel having outwardly facing limbs.
  • the limbs are folded to define flanges 142 and 144 which extend towards, and abut, the second shoulders 118 and 120, respectively.
  • the edges of the flanges 142 and 144 at intervals along their length are provided with projections (not shown) which engage within complementary openings formed in the adjacent surfaces of the tapered sections 122, 124.
  • the dove-tailed edges of the panels 1 and 2 are clamped between the flanges 104 and 112, the flanges 102 and 110, and the correspondingly shaped regions of the part 21, by a nut 22 and a bolt 23.
  • a spacer 24 maintains the parts 20 and 21 at a desired separation. The wedging action between the surface 14 and the flange 1 12 during clamping causes the shoulders 13 of the panels 1 and 2 to abut against the shoulders 31 and 32 of the sections.
  • the gaskets 100 abut the surfaces 4, 5, 6 and 7 of the panels 1 and 2 in the region between the folds 62 and 63 thereby preventing the ingress of moisture to the interior of the panels.
  • the voids defined by the limbs of the U-shaped members, flanges 144, 104, 1 12 and the shoulder 32 are filled with a fire-resistant material which has channels in the vicinity of the holes formed in the flanges 104 and 144 so as to allow passage of the bolts 148.
  • shaped voids in the rest of the structure are also filled with fire-resistant material.
  • the gap between the flanges 142 and 144 and the cover 46 is also filled with a fire-resistant material.
  • the jointing arrangement 3 can be connected to a rigid structure by extending the bolt 23 through one of the covers, in a manner similar to that shown in Figure 7.
  • Each of the parts 20, 21 when assembled forms on opposite sides of the bolts 23 a pair of closed box sections which are filled with heat insulating material.
  • the parts are therefore very stiff in the longitudinal direction to resist distortion due to heating whilst at the same time they can yield to allow relative movement of adjacent panels in the blast situation.
