Description

A FIRE SAFETY ARRANGEMENT FOR OVERHEAD PIPE SUPPORT ARRANGEMENTS AND A METHOD OF INSTALLING SAID FIRE SAFETY ARRANGEMENT

FIELD OF THE INVENTION

[001] This invention relates to a unique arrangement for fire insulating and protecting the support structure for overhead pipe mounted to ceilings.

[002] More particularly, this invention relates to a unique arrangement and method for being able to fireproof overhead pipe port arrangements within buildings in situ, conveniently, consistently and aesthetically.

BACKGROUND ART DISCUSSION

[003] As part of the support structure for having overhead pipes mounted to the ceiling there is the requirement to use conventional pear band pipe hangars or sometimes simply referred to as loop hangars.

[004] These conventional loop hangars for the most part are made up of a strip of stamped steel formed with a loop profile that resembles the shape of a pear.

[005] To appropriately support the pipe to the ceiling, the loop has dimensions to closely fit the diameter of the pipe to be supported overhead.

[006] When the loop hangar or, again as sometimes referred to, the pear band pipe hangar is being installed, the hangar is firstly placed around the pipe where the legs of the loop circle the pipe and at the distal end of each leg of the loop hangar include lateral tabs or extension with holes that align when overlapped so as to allow a rod that has been mounted to the ceiling to pass there through.

[007] In conventional mounting methods utilising these loop hangars to support the overhead piping, once the rod mounted to the ceiling has passed through the aligned holes of the horizontal tab extensions extending out from the top of each leg which has formed itself circumferentially around the periphery of the pipe, the rod can be secured to the loop hangar using an appropriate nut and washer from both the top and underside of the overlapping horizontal extensions.

[008] The mounted threaded bolt to the ceiling along with the loop hangar which will be responsible for providing the support arrangement for the overhead pipes must meet certain standards when it comes to fire protection.

[009] It is important that in the event of a fire the loop hangar maintains its integrity to effectively maintain support for the overhead pipes.

[010] At present there are a number of methods employed for imparting fire retardancy to these kinds of exposed overhead pipe support arrangements utilising the pear band pipe hangar with the most simple method involves the fairly random hand moulded sculpturing of a fire retardant settable material about the overhead pipe support components.

[011] As there is no recognisable method to apply the fire retardant product to the overhead pipe support arrangement using these ad hoc conventional methods, in many instances the resultant outcomes are anything but acceptable, both functionally and aesthetically.

[012] Quite often, in order to make sure that adequate amounts of the fire retardant material have been added to the overhead pipe support components, excess material is applied, and as settable fire retardant material is often packed in using the hands of the applicator or in some instances even sprayed on, the final result has the fire retardant material being set about the overhead pipe support arrangement haphazardly and without consistency, thereby leaving behind a visually very unappealing and potentially incomplete fire protected feature within the building.

[013] Accordingly, it would be particularly advantageous to be able to provide for an arrangement that would allow a simple method for applying the settable fire retardant material to the exposed overhead pipe support arrangement so that the fire retardant material, when set, could be of the appropriate thickness, density and consistency to establish the requisite fire retardant functionality necessary to appropriately safeguard the overhead pipe support arrangement, supporting the pipes in the event of a fire and while at the same time imparting this outcome in an aesthetically pleasing configuration.

[014] Therefore it is an object of this invention to provide such a fire safety arrangement for an overhead pipe support arrangement that will allow for a method of installing settable fire retardant material to encapsulate the exposed overhead pipe support arrangement in such a way that it will overcome the problems and shortcomings that were introduced above.

[015] Further objects and advantages of the invention will become apparent from a complete reading of the following specification.

SUMMARY OF THE INVENTION

[016] In one form of the invention there is provided a fire safety arrangement for an overhead pipe support arrangement, said fire safety arrangement including: [017] a multiplicity of moulds fillable with settable fire retardant material wherein each mould is configurable so as to be fixably mountable about an exposed overhead pipe support arrangement when filled with the settable fire retardant material so that upon removal of said multiplicity of moulds when said settable fire retardant material has set, the exposed overhead pipe support arrangement is encapsulated within said fire retardant material.

[018] Advantageously, as opposed to simply hand sculpturing and/or spraying or trolling the settable fire retardant material on an ad hoc basis about the exposed overhead pipe support arrangement, by being able to configure a multiplicity of moulds that can be fixably mounted about the exposed overhead pipe support arrangement, this means that the appropriate amount of fire retardant material can be ‘set’ so as to make sure that once the fire retardant material has formed in place it will be of the appropriate thickness, density and consistency to impart fire resiliency to the pipe support arrangement and to do so in an aesthetically pleasing resultant application.

[019] In a further form of the invention there is provided a fire safety arrangement for an overhead pipe support arrangement, said fire safety arrangement including: [020] a mould fillable with settable fire retardant material wherein the mould is configurable so as to be fixably mountable about an exposed overhead pipe support arrangement so when the mould is filled with the settable fire retardant material and said settable fire retardant material has set, the exposed overhead pipe support arrangement is encapsulated within said fire retardant material and the set fire retardant material remains enclosed within the mould fixably mounted to the exposed overhead pipe support arrangement.

[021] Advantageously, in this embodiment of the invention the mould remains fixed to the exposed overhead pipe support arrangement with the set fire retardant material remaining enclosed within the mould.

[022] As with the other embodiment introduced above for this invention the appropriate amount of fire retardant material can be ‘set’ so as to make sure that once the fire retardant material has formed in place it will be of the appropriate thickness, density and consistency to impart fire resiliency to the pipe support arrangement, but in this further form of the invention the mould remains fixed permanently, so the set fire retardant material can’t be damaged, knocked off and/or erode away prematurely.

[023] In preference the exposed overhead pipe support arrangement includes a loop hangar and/or a pear band pipe hangar and when the pipe is supported in the loop hangar and/or the pear band pipe hangar, the loop hangar and/or the pear band pipe hangar is in-filled with the settable fire retardant material prior to the mould being fixed mounted about the exposed overhead pipe support arrangement.

[024] In preference each mould includes a pair of clamp moulds, wherein the pair of clamp moulds are configured to be fixably clampable about said loop hangar.

[025] In preference each clamp of the pair of clamp moulds are assembled from a flat pack arrangement so that the moulds can be easily manufactured, packaged and transported and when required for use can be assembled from the flat pack arrangement into a configuration required for installation about the exposed overhead pipe support arrangement.

[026] In preference the mould or parts thereof are made of stainless steel.

[027] In preference when the pipe is supported in the loop hangar and/or the pear band pipe hangar, the loop hangar and/or the pear band pipe hangar is in-filled with the settable fire retardant material prior to the multiplicity of moulds being fixably mounted about the exposed overhead pipe support arrangement.

[028] An advantage of introducing this further step into the invention is that in the event of bringing together the multiplicity of moulds fillable with the settable fire retardant material together about the exposed overhead pipe support arrangement, in order to make sure that there is consistency and to avoid the potential of any pockets of air and so forth that would impact efficiencies in the set fire retardant material to function as required in the event of fire, [029] The in-fill of the enclosed area of the loop hangar and/or the pear band pipe hangar can then be neatly trolled off before the introduction of the mounting of the multiplicity of moulds to the overhead pipe support arrangement.

[030] In preference the multiplicity of moulds includes a pair of clamp moulds, wherein the pair of clamp moulds are configured to be fixably clampable about said loop hangar.

[031] In preference in one embodiment of the invention, each clamp mould of the pair of clamp moulds at a first distal end is joinable to the other clamp mould through a hinged arrangement.

[032] In preference the hinged arrangement is lockable.

[033] In preference each mould of the pair of clamp moulds, at a second distal end, includes a semi-circular vertical extension so that upon joining the pair of clamp moulds each vertical semi-circular extension aligns with the other so as to allow a ring collar to fixably secure the pair of clamp moulds together at said second distal end.

[034] In an alternative embodiment of the invention, instead of having the hinged arrangement at the first distal end of each clamp, in this further embodiment the first distal end also includes a longitundinal semi-circular extension on each clamp so that when the respective clamp moulds of the pair of clamps are fixably mounted about the loop hangar, the respective longitudinal semi-circular extensions at the first distal end of each clamp member align so that a ring collar can be fixably secured about the aligned semi-circular extension at the first distal end of each clamp so as to fixably join the pair of clamp moulds together at that first distal end.

[035] In preference each clamp mould resembles on a side profile, the shape of a pear consistent with the outside profile of a loop hangar in which the pipe is being supported therein.

[036] In preference the two contact edges of each clamp mould, wherein each of these contact edges will contact the corresponding two contact edges of the adjacent clamp mould of the pair of clamp moulds when the pair of clamp moulds are fixably clampable about the loop hangar, include as part of the respective edge profile of the contact edge, a generally semi-circular inlet or slot so that when the pair of moulds are joined together these semi-circular inlets or slots of the respective clamp moulds closely fit the outside diameter of the pipe being supported by the loop hangar.

[037] In preference each semi-circular inlet of the respective contact edges of the clamp mould include an internal tab extensions so that when the semi-circular inlets align with the corresponding semi-circular inlets of the adjacent clamp mould to closely fit the outside circumferential edge of the pipe being supported, the internally oriented extension tabs provide clearance for an overflow of settable fire retardant material out through the clamp moulds as the pair of clamp moulds are fixably clamped about the loop hangar.

[038] Advantageously, by introducing these unique extension tabs around the edge of the semi-circular inlets, means that the pair of clamp moulds when being joined together can still closely fix and clamp themselves to be outside of the pipe being supported but with the minimal amount of clearance being provided by these additional extension tabs provides an indicator to the applicator installing the fire retardant material, that the moulds have been adequately filled with the settable fire retardant material and there are no gaps or pockets left un-filled within the clamp mould which could be confirmed by the fact that fire retardant material would then appropriately ooze out from the clearance created by the extension tabs to be then neatly trolled off.

[039] In preference each clamp mould includes a series of slots positionable laterally across the breadth of the clamp allowing the ability of settable fire material contained within the clamp to overflow there through.

[040] Advantageously, again by introducing the slots into the overall structure of the clamp moulds provides for further identification points for the installer that the adequate levels of settable fire retardant material have been packed into the multiplicity of moulds as they are fixably mounted about the overhead pipe support arrangement.

[041] In preference each clamp mould of the pair of clamp moulds includes a male or female mating member so that the male or female mating member can appropriately align with a corresponding male or female mating member of the adjoining clamp mould when the pair of clamp moulds are fixably clampable about the loop hangar so as to assist vertical alignment of each clamp mould with the other clamp mould.

[042] In preference the engaging edges of the clamp mould include at least two tab extensions to assist in side alignment of each clamp mould when the pair of clamp moulds are fixably clampable about the loop hangar.

[043] In preference the two contact edges of each clamp mould, wherein each of these contact edges will contact the corresponding two contact edges of the adjacent clamp mould of the pair of clamp moulds when the pair of clamp moulds are fixably clampable about the loop hangar, include as part of the respective edge profile of the contact edge a slot, wherein the slot can be engaged with tooling, such as a screw driver to wedge on the pair of clamp moulds after the fire retardant material has settled.

[044] In preference the multiplicity of moulds includes a pair of longitudinal semicircular moulds, wherein the pair of longitudinal semi-circular moulds are configured to be fixably clampable about the threaded rod mounted to the ceiling and partially inserted through the concentric holes and secured to the loop hangar at one end.

[045] Hence in the preferred embodiment the multiplicity of moulds includes firstly the pair of clamp moulds which are configured to fixably clamp about the loop hangar and then the additional pair of longitudinally orientated pair of longitudinal semicircular moulds which are adapted to be fixably clampable about the mounted threaded rod.

[046] Hence the exposed overhead pipe support arrangement in preferred embodiments of the invention can be uniquely encapsulated through the unique configuration of the way in which the clamp mould and semi-circular moulds are brought together to fixably engage so as to confine the settable fire retardant material in place so that upon setting, those multiplicity of moulds can then be removed leaving the overhead pipe support structure completely encapsulated appropriately with the set fire retardant material with the appropriate thickness, density, consistency and aesthetics required.

[047] In preference the fire safety arrangement further includes a spacer so as to appropriately align and symmetrically position the pair of semi-circular moulds together about the mounted thread rod of the overhead pipe support arrangement.

[048] In preference the spacer includes a plurality of radial arms extendible out from a central slot wherein the central slot is of a comparable diameter so as to closely fit or engage with the periphery of the threaded rod.

[049] In preference the spacer includes a pair of forked laterally extending arms wherein the dimensions between the forked arms are of comparable dimension to the threaded rod of the overhead pipe support arrangement.

[050] In preference each forked arm includes a raisable tab adapted to engage with a nut threaded to the threaded rod so as to prevent the spacer from rotating once the spacer has been nested about the threaded rod.

[051] It is very important when bringing together the two semi-circular moulds about the threaded rod that they are symmetrically aligned about the threaded rod, otherwise it could result in the setting of the fire retardant material about the threaded rod such that a certain side or portion of the fire retardant material will be thicker in one section when compared to another about the threaded rod.

[052] By uniquely introducing the spacer of this invention, it will assist in appropriately symmetrically aligning the two semi-circular moulds as they are brought together and fixably configured about the threaded rod connected to the loop hangar and mounted to the ceiling.

[053] The inclusion of the forked arms and the space there in between helps to guide the spacer to nest on the threaded rod and then through the further inclusion of the tabs upon each of the forked arms, these tabs can then be raised to engage the bolt threaded onto the threaded rod which then prevents the spacer from rotating or becoming disorientated or dislodged as it is placed upon the threaded rod.

[054] In preference, prior to the clamping of the multiplicity of moulds upon the exposed overhead pipe support arrangement to put in place the settable fire retardant material, the threaded rod and/or the loop hangar includes wound wire.

[055] Advantageously the introducing of the wound wire to the components making up the overhead pipe support arrangement, including the threaded rod and the loop hangar, adds a feature to enhance the setting of the fire retardant material in place upon the overhead pipe support arrangement.

[056] In preference the multiplicity of moulds are each assembled from a flat pack arrangement so that the moulds can be easily manufactured, packaged and transported and when required for use can be assembled from the flat pack arrangement into a configuration required for installation about the exposed overhead pipe support arrangement.

[057] In preference the multiplicity of moulds or parts thereof are made of stainless steel.

[058] In order now to describe the invention in greater detail a series of preferred embodiments will be presented with the assistance of the following illustrations and accompanying text.

DETAILED DESCRIPTION OF THE DRAWINGS

[065] Referring to the drawings now in greater detail wherein the complete fire safety arrangement of this invention in a preferred embodiment is best seen generally as (10) in Figure 4.

[066] The fire safety arrangement (10) includes a pair of joinable clamp moulds (12) and (14) best observed when referencing Figures 1Aand 1B and Figure 4.

[067] Each clamp mould (12) and (14) at their upper distal end (15) and (17) includes a semi-circular vertical extension wherein when the respective clamp moulds (12) and (14) are brought together as shown in Figure 4 the aligned semicircular extension tabs (19) and (20) can then be fixed together through a ring collar (not shown).

[068] At the base ends (16) and (18) of the respective clamp moulds (12) and (14) shown as features (21) and (22) is a lockable hinged arrangement which allows the respective clamp moulds (12) and (14) to be hingedly clamped together at the respective base end (16) and (18) of the clamp moulds (12) and (14).

[069] Clamp mould (12) includes a side profile referenced as (23) generally consistent with the shape of a pear.

[070] The same profile exists for clamp mould (14) wherein the pear profile is referenced as number 24.

[071] Clamp mould (12) includes front face (25) and corresponding rear face (26) (not shown) and clamp mould (14) includes the same configured front face (27) and the underside face (28).

[072] Clamp mould (12) includes contact edges (1) and (2) which align and contact with contact edges (3) and (4) of clamp mould (14) when the clamp moulds (12) and (14) are joined together as shown in Figure 4.

[073] These contact edges (1), (2), (3) and (4) of the respective clamp moulds (12) and (14) include as part of their profiling unique features which will assist in appropriately joining together the respective clamp moulds (12) and (14) and also ensure that during the fixing of the clamp moulds (12) and (14) to the overhead pipe support arrangement that adequate settable fire retardant material has been introduced into the respective clamp moulds (12) and (14).

[074] As part of the contact edge profiles (1) and (2) of mould (12) a male dimple (31) and (32) (not shown) is adapted to engage corresponding grooves (33) and (34) of the contact edges (3) and (4) of clamp mould (14) so as to assist the up and down alignment of the respective clamp moulds (12) and (14).

[075] Contact edges (1), (2), (3) and (4) also include slots within the profile shown as (35) on clamp mould (12); and (37) and (38) on clamp mould (14) which is best seen in Figure 4, provide for a slot in which tooling such as a screw-driver can be wedged there in between the created slot so that when the fire retardant material has set this tooling can assist in wedging apart the respective clamp moulds (12) and (14).

[076] Also as seen when referencing Figures 1A, 1B and Figure 4, tab extensions (41a), (41b), (41c), (41 d) can align with grooves or markings shown as (42a) and (42b) in Figure 1A to assist in side alignments during the bringing together of clamp moulds (12) and (14).

[077] Clamp mould (12) along the contact edges (1) and (2) includes a semi-circular inlet (29) to which the same profiled semi-circular inlet shown as (30) in clamp mould (14) and its respective contact edges (3) and (4) means upon bringing together of the clamp moulds (12) and (14) these two semi-circular inlets (29) and (30) provide a means to which the clamp moulds (12) and (14) can be tightly closely fit about the pipes being supported by the loop hangar encapsulated within the joined together clamp moulds (12) and (14).

[078] Importantly however the semi-circular inlets shown as (29) and (30) also include a series of tab extension shown as (46) in Figure 1A and (45) in Figure 1B wherein there is a degree of clearance provided for by these tabs which will allow the settable fire retardant material to ooze out acting as a marker to the installer of the fire safety arrangement that adequate settable fire retardant material has been infilled into the clamp moulds (12) and (14) as they are fixed about the loop hangar.

[079] As the person skilled in the art would appreciate, once the settable fire retardant material overflows out through the clearance created by tabs (45) and (46) this material can then be neatly trowelled off.

[080] Figure 2 illustrates the pair of longitudinal semi-circular moulds (48) and (50) which are configured to be fixably clampable, shown by way of arrows (51) and (52) in Figure 4 about the threaded rod (53) which is mounted at one end to the ceiling shown as (71) and at the other end to the loop hanger (not shown) in Figure 4, which would be encapsulated by the clamp moulds (12) and (14).

[081] The loop hangar (54) is shown in Figure 5 wherein the threaded rod (53) is mounted to the loop hangar (54) through the nut (57) of which there would be a corresponding nut (not shown) on the under-side of the loop hangar (54).

[082] It is also notable from Figure 5 that prior to the clamp moulds (12) and (14) and the longitudinal semi-circular moulds (48) and (50) being fixed about the overhead pipe support arrangement, the threaded rod is wound by wire shown as (55) and so too the loop hangar (54) is wound by wire (56).

[083] This wound wire assists in allowing the settable fire retardant material about those features.

[084] Also shown in Figure 5 is a representative example as to how the spacing between the pipe (70) being supported within the loop hangar shown as (59) can first of all be in-filled with the fire retardant settable material shown as (73) prior to the fixing of the clamp moulds (12) and (14) and the longitudinal semi-circular moulds (48) and (50).

[085] Figure 3 illustrates a spacer (60) which is important in the orientation of the longitudinal semi-circular moulds (48) and (50) about the wire wound threaded rod (53).

[086] The spacer (60) includes a series of radial arms (62) which, once the spacer (60) is nested upon the threaded rod (53), assists in bringing together the longitudinal semi-circular moulds (48) and (50) so that the in-filling of the settable fire retardant material is done evenly for consistency about the threaded rod (53).

[087] The spacer (60) also includes the unique forked arms (75) which assist in guiding the spacer (60) upon the thread (53).

[088] These forked arms (75) also include raisable tabs shown as (69) which once the spacer (60) is positioned about the threaded rod (53) these can be raised up to engage the nut (72) thereby fixing the spacer (60) in place upon the threaded rod (53) preventing it from actually rotating or dislodging or mis-aligning.

[089] The discussions of the preferred embodiment shown in Figure 1A through to Figure 5, while being illustrative of embodiments of the invention, these examples should not be restrictively considered as the complete scope of the invention as claimed hereafter.
