Description
SPECIFICATION
Panel element for use in constructing insulating chambers and casings
The invention relates to a panel element for use in constructing insulating chambers and casings, more particularly for ventilating and air conditioning systems. Such panel elements generally comprise an inner part made of insulant and clad externally with metal members. The invention also relates to an insulating casing for air conditioning systems, cold chambers, ventilation appliances or the like, the casing being prepared from such panel elements.
Large modern buildings are usually provided with central air conditioning systems which maintain an adequate air circulation and adequate temperatures in the conditioned rooms. Systems of this kind are usually installed either on the roof or in the cellar of such buildings. Because of the noise they make and the heat they evolve, the conditioning systems comprising a number of individual units such as fans, coolers and heaters, are placed in separate heat-insulated and sound-insulated chambers which may be placed inside the rooms of the building. The insulating chambers are usually formed from panel elements of standardized dimensions whose interior consists of an insulant several centimetres thick, metal cladding members being placed all round the internal insulant and stuck thereto.The panel elements are assembled to form the insulating chambers or casings with the use of connectors, e.g. lugs or the like which are formed on the cladding members and project therefrom outwardly or inwardly. One disadvantage of these known panel elements is that in some respects the sound and heat insulation they provide is unsatisfactory, since the metal cladding members present on the abutting surfaces of the discrete panel elements unless additional sealing inserts are introduced and, sheet metal being a relatively good conductor of heat, the cladding members form heat bridges. Another disadvantage is that an insulating casing devised from known panel elements of this kind is not very rigid, a feature which may be very important in the particular context of casings used for portable conditioning and ventilating facilities.Because of the reduced resistance to torsion, the connections between the various panel elements may work loose during transportation and thus greatly reduce the insulating effect.
When known panel elements of this kind are used to insulate e.g. relatively large cold chambers, the disadvantage of occassionally inadequate insulation is compounded by assembly difficulties, since the various panel elements can be interconnected only from one side i.e., from inside the room or chamber.
One conventional way of overcoming these difficulties has been to use frames and sealing strips for mounting the panel elements, Conventional panel elements used for air conditioned chambers or the like do not have standardized fixing points for assembly of the discrete panel elements and for the assembly and retention of the individual units.
It is an object of the invention to provide a panel element for use in constructing insulating chambers and casings, more particularly for ventilating and air conditioning systems, the panel element having inherent stability and resistance to torsion, ensuring high insulation when fitted without extra action being needed and enabling the various units of the complete systems to be secured reliably and stably in convenient positions.
In accordance with the present invention the edges and the end faces of each panel element are each covered by a substantially channel section end member whose arms extend generaly parallel to the outside surfaces of the panel element and are rigidly secured to the edges of the cladding members the central part of the end member being formed with at least one groove receiving a sealing strip made of a resilient insulant. The channel section end members rigidly connected to the outside surfaces of the cladding members give the panel elements great torsional strength and also serve as a reliable securing and location for the resilient insulating sealing strips which are integral components of the panel elements.When the panel elements are assembled in abutting relationship with one another to form an insulating casing, two oppositely disposed resilient sealing strips enter into bearing relationship with one another, thus ensuring very effective sealing and, therefore, the required high level of heat and sound insulation.
In a convenient development of the invention, the edge zones of the cladding members cover the arms of the channel section end members; if required, both parts can also be stuck together. These highstrength double layers make it possible for these additionally stiffened zones to be provided with tapped rivets to receive screws, thus enabling adjacent panel elements to be rigidly interconnected by way of connectors or discrete units of the insulated systems to be secured.
In accordance with another development of the invention, the end edges of the cladding members are bent towards the end face and into the grooves so that their ends can serve as means to secure the resilient sealing rings engaged in the grooves.
Sealing strips can therefore be reliably secured and located in the grooves without the need for additional items.
For stable securing of the panel elements with the use e.g. of longitudinal members or uprights, further tapped rivets are secured to the abutting surfaces carrying the end members in the central plane of the panel elements, it being possible for a groove and associated sealing strip to be disposed in the adjacent part of the panel element on either side.
Very conveniently, the sealing strips can take the form of a substantially oval cross-section rubber memberwhich prior to the assembly of a number of panel elements protrudes partially from its groove and is formed in the part disposed in the groove with an inclined blind slot for receiving the bent-round end edge of the associated cladding member.
An insulating casing prepared from the novel panel elements and of use for air conditioning systems, cold chambers or the like can comprise a bearing framework embodied by rigidly intercon nected corner uprights and longitudinal and transverse spars or beams or the like embodied by torsionally resistant hollow section members having at leasttwo side surfaces at right-angles to one another and one open side. A number of panel elements are placed between the uprights and spars or the like and rigidly interconnected by connectors.
Conveniently, the connectors can take the form of
L-section members formed in each arm with at least one aperture to receive a screwed fastener, the fastener engaging in tapped rivets provided on the outside surfaces of the panel elements. The L-shape of the connectors enables two panel elements to be rigidly interconnected, for which purpose two section members are necessary, and the various units of the conditioning or refrigerating systems can also be secured to the projecting parts of the connectors.
Conveniently, the corner uprights and the longitudinal members are square section members with one corner removed and inwardly and inclinedly bent end edges of the two exposed webs, so that the contiguous panel elements can be secured from inside the upright by screwthreaded fasteners screwed into the tapped rivets on the panel element end faces.
The invention will be described now by way of example only with particular reference to the accompanying drawings wherein:
Figure lisa cross-sectional view of a panel element;
Figure 2 is a view on an enlarged scale of the portion A of Figure 1, the portion A comprising a corner edge and a sealing strip engaged in the groove;
Figure 3a shows how two adjacent contiguous panel elements are interconnected by connectors;
Figure 3b is a side view of the connectors secured axially to a panel element;
Figure 4 is a cross-section through two panel elements secured by way of their corners to a spar or the like, and
Figure 5shows a casing assembled from panel elements of various standardised sizes.
A panel element 1 shown in Figures 1 and 2 comprises an inner portion 2 made of a substance which is a sound and heat insulant such as nonflammable mineral wool or a light foam material.
Metal cladding members 3,4 are stuck one to each of the two major outside surfaces of the part 2 and to cover all of each outside surface. Disposed in the edge zones of each panel element are end section members 5, 6 which are made of a relatively rigid sheet metal and are in cross-section substantially channel-shaped. The end members on the various sides of the panel element are identical and so only of them will be described in detail hereinafter. Arms 7,8 of member 5 are covered by the edge regions of the two cladding members 3,4 and are rigidly connected to such regions by tapped rivets 9, 10. The arms 7,8 can also be secured to the edge regions of the cladding members 3,4 by sticking.A central part 11 of end member 5 covers the end faces of the insulating interior part 2 and is formed in the centre-planeofthe panel element with an aperture receiving an end face tapped rivet 12. Adjacent each rivet 12 is a groove 13 which receives a sealing strip, to be described in detail hereinafter with reference to
Figure 2.
The groove 13 is substantially rectangular in cross-section and serves to receive a sealing strip 14 which is in the form of a substantially oval crosssection rubber section member and protrudes to some extent from groove 13. In the part received in the groove, the ring 14 is formed with a blind slot 15 in which end edge 16 of cladding member 4 engages. As will be apparent, each cladding member 3,4 is larger than the outside surfaces of the panel element and has its projecting edge so bent around web 17 of end member 11 that its end edge 16 extends into groove 13 and can serve to retain the rubber member 14. The strip 14 has a hollow interior 18 for improved resilience and therefore improved sealing tightness.
Figure 3a shows two panel elements 1 assembled together in abutting relationship to secure the two elements 1 together, two identical connectors 20a, 20b are provided on each side. The two connectors 9 20a, 20b shown in chain lines on the right-hand side of Figure 3a are used only when the insulating walls are accessible from inside the chamber and from outside the chamber. Each connector 20a, 20b, is a section member of L-shaped cross-section, the two arms 21,22 possibly being braced relatively to one another by a pressed-out web 23 and being formed each with a central aperture 24, 25 to receive a respective fixing screw (not shown).The connectors 20a, 20b can, when arranged in pairs as shown in
Figure 3a, provide a strong and, because of the pairwise engagement of the rubber strips 14, a sealing tight connection between two panel elements 1. Also, the various units of the system to be insulated can be secured to the projecting arms of the connector pairs 20a, 20b. Figure 3b shows two connectors 20a as shown in Figure 3a but rotated through 90 in relation to Figure 3a.
Figure 4 shows how two panel elements 1 are secured to a corner upright 30 of a bearing framework. As will be apparent, the corner upright 30 takes the form of a square section member having two side surfaces 31,32 at right-angles to one another and formed with a continuous diagonal aperture 33 by cutting away the fourth corner, the aperture 33 being covered by a releasable metal member 34. The other two side webs 35,36 are bent so they are inclined towards in their terminal parts 37,38 and serve to retain the covering member 34.
With the member 34 removed, screwthreaded fasteners can be screwed, by way of apertures 39,40 in the two side walls 31,32 of the upright 30, into the tapped rivets 12, so that the various panel elements 1 are rigidly connected to the corner uprights 30.
Compression of the sealing strips 14 against the upright walls 31,32 ensures a sealing-tight engagement between the panel element end faces As is also shown diagrammatically in Figure 4, stirrup-like holders 41 can be screwed to the inside or outside of the panel elements so that either the casing itself can be secured to the outside walls of a room or the various units of the items to be insulated can be secured to the members 41.
Figure 5 shows an insulating chamber which has been assembled from the panel elements shown in
Figure 1 and inside the enclosed interior of which a multi-element conditioning system for a large building, e.g. a tower block, can be placed. As will be apparent, the insulating chamber takes the form of a number of panel elements of a standardised size, e.g. to a 305 mm module. The panel elements 1 are secured to one another by way of their end faces in the manner described and also to longitudinal and transverse spars or the like 45,46, the elements 45, 46 being connected to the corner uprights 30 to form a supporting or bearing framework. The insulating chamber shown rests on a bottom frame of channel section bars 47,48.
The use of the panel elements in accordance with the invention is not restricted to insulating casings or chambers for fixed installations. Because of the high torsional resistance of the panel elements both on their own and when joined together, mobile equipment, such as compressors for building sites and other noisy items, can be heat and sound insulated by means of the novel panel elements. The particular technical advantages which the invention provides are that high insulation is provided immediately upon assembly without the need for additional external or internal sealing, and there is great flexibility in the manner in which the panel elements can be connected and secured to one another and to the various horizontal and upright members of the framework and, more particularly, further retaining means or holders or the like can be fitted and secured for individual units. The great flexibility of the panel elements arises mainly from the provision and very strong retention of the tapped rivets in the specially strengthened edge zones of the panel elements.
