Definitions
- This invention relates to an arrangement for jointing adjacent panels in order to erect heat-insulative structures of the type comprising, on opposite longitudinal sides of each panel, respective joint members which are formed integrally with their respective panel and adapted to engage with corresponding joint members on an adjacent panel by means of respective connector members.
- Panels of this type which are usually fabricated with a heat-insulative core of foamed resin sandwiched between two thin metal or plastics foils acting as reinforcements and boundaries for the resin, are customarily jointed together through end connections to erect refrigerated or controlled atmosphere rooms.
- the underlying problem of this invention is to provide a jointing arrangement which is structurally and functionally conceived to obviate all the drawbacks with which the cited prior art is beset.
- joint members comprise, on each side of each panel, at least two spaced-apart, parallel mortises which extend longitudinally of their respective panel side, and that said connector members are interposed between the corresponding mortises on adjacent panels and snap secured on the panels at the location of said mortises.
- Respectively shown at 1 a and 1 b in the accompanying drawings are two heat-insulative panels (only partly depicted) which are used to erect an enclosed structure, e.g. a refrigerated room and/or controlled atmosphere room.
- Each panel 1 a,b comprises two opposite foils 2, 3 which are spaced apart and define respective panel walls 2a, 3a, being folded over at each longitudinal panel side 4 to form a respective channel- like, dovetail recess which will be referred to hereinafter as the mortise on account of its function.
- Such mortises are respectively denoted by the reference numerals 5a, 6a and 5b, 6b on their respective panels 1 a, 1 b.
- the panel construction is completed by a heat-insulative layer, generally indicated at 7, of foamed resin interposed between the foils 2, 3.
- the panels are connected together, in the joint region, by means of two oppositely located eaves, both indicated at 8, made of sheet metal bent to the shape shown in Figure 3, thereby to define, along the opposite longitudinal edges, two formations 8a,b substantially C-shaped in cross-section, which are deformable elastically and adapted to snap fit over the corresponding bead 9 of each panel defined between the wall 2a, 3a and the corresponding adjacent mortise 5a,b and 6a,b, respectively.
- this seal is a lip seal 10a having a web 10b received is a seat 10c formed in the corresponding back wall of the respective C-shaped formation 8a,b.
- an injection chamber 13 for a resin similar to resin 7 constituting the panel core and adapted to be foamed is defined in the space between the sides 4 of the facing panels and the corresponding eaves 8. This resin is injected through respective holes 11 formed at pitch distances along one of the eaves 8.
- the eaves 8 may be affixed to their respective panels by rivets 12 ( Figure 3). This expedient, along with the possible provision of a central web on the eaves 8, can improve the resistance of the latter to the pressure generated inside the chamber 13 while the resin is being foamed.
- Push-fit plugs 14 carrying a covering for the rivets 12 are provided to conceal the holes 11 after sealing the chamber 13.
- hooking means In order to anchor the panels 1 a,b to purlins 15 or the like load-bearing structures, hooking means are provided which include a hooked formation 16 braced by means of two stays 17, 18 to two corresponding flitches 19, 20 respectively received between the mortises 6a,b and 5a,b. Tubular spacers 21 are provided between the flitches 19, 20 which fit over their respective stays 17, 18 coaxially therewith.
- a heat-insulative material 22 is effective to prevent the formation of thermal bridges between the inner wall 3a to the refrigerated room and the outside.
- the second flitch 20 and its stay 18 are omitted.
- each tenon will have a rod-like shape having substantially the same length as the corresponding mortises and be approximately coincident, therefore, with the longitudinal extent of a panel.
- Said tenons 30 snap fit, in a substantial mating shape relationship, into the two corresponding mortises 5a,b and 6a,b facing each other on the respective panels.
- the former are preferably shaped to present, in cross-section, two pairs of lugs, respectively shown at 31 a,b for the first pair, and at 32a,b for the second pair, which are all substantially trapezoid in shape and united through opposite minor bases thereof.
- the lugs 31 a,b and respectively 32a,b, of both pairs are disposed at a spacing from each other, as shown in the figure, for better deformability of the tenons.
- the joint between the two panels 1 a,b may be sealed with a conventional sealant, e.g. of the silicone variety.
- the tenons may have an integral joint covering as in the exemplary tenon shown in Figure 6.
- the joint covering comprises a substantially T-shaped projection 41 extending sideways from the tenon with its web co-planar with the minor bases of the lugs 31 a,b and 32a,b.
- the tenons 50 are arranged to hold the two panels 1 a,b spaced apart.
- the projection 51 forming the joint covering for the joint between the panels has two parallel webs 51 a,b set mutually apart and extending square from one and the same flange 51 c.
- any anchoring to purlins or the like load-bearing structures may be effected by using the previously described hooking means and breaking the corresponding tenon continuity over a length corresponding to the mortise region occupied by the flitches.
- the jointing arrangement of this invention has several advantages over the known arrangement, valuable as these may be. First, full standardization of the panels is afforded, whether these be intended for dry joint or injected resin foam assembling.
- An additional, important advantage is that, at the room erection stage, the means for hooking on the purlins can be shifted, while achieving a more versatile and stronger anchoring for the panels.
