Description

SPECiFICATION Wall or roof elements composed of a foamed core and metallic covering layers This invention relates to wall or roof elements comprising two metallic covering layers with a foamed core therebetween, the covering layers being formed with longitudinal edges defining tongue-and-groove snap connections. The invention also relates to a combination of two or more such wall or roof elements, in which case two resilient seals are fitted between each pair of elements.

Such wall or roof elements have the especial advantage of easy assembly, since the snap connection enables a prealignment of the wall or roof elements to be connected together.

in one insulating panel as described in West German Gebrauchsmuster DEGM 81 08 886 it is considered as being worthy of improvement that the outwardly positioned seal is acted upon directly by weather conditions. Because of this, embrittlement of the seal can lead to a degradation of the sealing effect. Also, movements of the panels in the longitudinal and transverse planes due to the effects of wind and temperature lead to an opening of the sealing region and thus again to a decrease in the effectiveness of the seal. Moreover, in the case of fire the longitudinal connection between the parts opens up very easily and destroys the seal due to it being subjected directly to the heat. The seal is a special profile.Usually, it has to be matched in terms of its colour to the appearance of the particular panels, without being able to utilise the optimum properties of black sealing materials which have a higher resistance to embrittlement.

ít is an object of the present invention therefore to provide wall or roof elements in which the sealing action against environmental influences, and possibly also in the case of fire, is reliably maintained, and which also permits the utilisation of simple sealing materials which have the optimum sealing effect.

This is achieved in accordance with the present invention by a pair of interengageable wall or roof elements each comprising two metallic covering layers with a core of foamed material therebetween, adjacent longitudinal sides of the elements being tongued-and-grooved for snap connection with two resilient seals between the elements, in which the seals are arranged internally within recesses of the grooved side and interact with prorninent longitudinal portions of the tongued side.

By this means the seals are protected against the direct action of environmental influences and fire, and a high degree of security is achieved against the splitting apart of the connection. Seals which are simple, economical, and yet highly resistant to embrittlement can be used, and indeed seals which are independent of the appearance of the particular wall or roof elements themselves.

Forthe sealing action, it is particularly advantageous, through increased surface pressure with small impressed forces, if in accordance with a further feature of the invention the prominent longitudinal portions of the tongued side are formed as knife-edge sealing lips.

A high stability of the lengthwise connection is achieved if the interengagement of the adjacent longitudinal sides comprises four metallic bordered tongue-and groove connections.

Preferably, the longitudinal edges of the covering layers at the tongued side are turned back on themselves through 180 at their ends to form said prominent portions, and these ends overlap the ends of the covering layers of the grooved side.

Preferably, the recesses have a part-circular cross-section to receive the seals and are defined by the end portions of the covering layers at the grooved side, and the ends of said end portions are turned back on themselves to form hookshaped ends.

By arranging that the element subtending the grooved side is provided with projecting lugs, the element subtending the tongued side is provided with matching retaining recesses, and the lugs and the retaining recesses define a stop by their abutment, one ensures a constantly accurate assembly of the parts in a simple manner and constancy of the compression of the seals.

The snap connection is preferably formed by lugs which are of substantially semi-circular form in cross-section and retaining grooves which are recessed substantially at right-angles to the surface of the elements.

Simple circular cross-section tubes can be used as seals.

According to requirements, in one embodiment of the invention, the seals for example may be arranged offset relative to each other in the plane of the elements and the ends of the recesses for the seals act as holders for a common fastening sheet between the two elements.

in order that the invention may be fully understood, two embodiments of wall or roof element in accordance with the invention will novw be described by way of example and with reference to the accompanying drawing, in which: Fig. 1 is a cross-sectional view, on an enlarged scale, through one longitudinal connection of two wall or roof elements; and, Fig. 2 is a corresponding cross-sectional view through a second longitudinal connection of two wall or roof elements, incorporating a fastening sheet.

As shown in Fig. 1, each of the wall or roof elements comprises an upper covering layer 1, a lower covering layer 2 and a central core 3 of foamed material. The longitudinal edge 4 of the left-hand element 5, which is grooved along the edge 4, and the longitudinal edge 6 of the righthand element 7, which is tongued along the edge 6, are designed to interengage as a snap connection 8 by the interengagement of upper and lower projecting lugs 9 and retaining grooves 10.

Each of the covering layers of the left-hand, grooved-edge element 5 is turned back on itself around the respective lug 9, forming an internal web 11 extending towards a part-circular recess 5 12 fitted with a seal 13. The end portion 14 of each covering layer beyond the respective recess is turned back through 180 , with the two end portions 14 held spaced apart by being embedded in a protuberance 15 of the foamed core 3.

Each of the covering layers of the right-hand tongued-edge element 7, a t 7, after being turned in define the respective retaining groove 10, forms a projecting web , 16 which terminates in a knife edge sealing lip 17 with the end 18 of the 5 covering layer turned back again through 180 .

The space between these ends 18 delimits a groove-like recess 19 in the foamed core 3 along the margin of the right-hand element.

The general groove in the left-hand element 5 West is denoted by the reference numeral 20 and the general tongue on the right-hand element denoted by the reference numeral 21. upon Along by the longitudinal margins 4 and 6 of the two interengageable elements there are thus four metallic bordered tongue and groove connections: namely I from groove 20 with lugs 9/tongue 21 with retaining grooves 10; II from recess 19/protuberance 15; and III and IV from the recesses 12/sealing lips 17.

By virtue of this quadruple connection there is a high the resistance to the elements splitting apart (tilting of the connected elements relative to other) in the event of an appropriate strain, and by reducing the spacing between the end to be portions 14 and of the sealing lips 17 one achieves a greater deformation of the seals 13 and therefore an increased properties of black sealing action.

The true ends 22 and 23 of the metallic end portions 14 and 18 respectively of the covering layers are protected by being embedded in which the foamed core 3. environmental influences, The lugs 9 and retaining grooves 10 abut one another, defining a "joint" 24, to facilitate their assembly.

@5 In order to assemble the parts, the outer faces of the sealing lips 17 on each side of the tongue 21 slide along and between the lugs 9 into or the groove 20. When comprising the thickest portion of the tongue 21 has passed the position of minimum width in the entry passage, after slight elastic outward bending of the lugs 9. the lugs 9 snap into with the retaining grooves 10 from their outwardly in ly bowed positions in a resilient The lugs 9 and retaining grooves 10 the define the and joint 24 and the knife-edge sealing lips 17 deform the seals 13.

In the modified embodiment shown in Fig. 2, the seals are of arranged offset relative to each The end portions 14 of the covering layers inwardly @0 of the two recesses 12 serve as holders for individual fitted securement sheets 25 which receive enclosed fastening screws which are shown but which are re indicated by the chain- dotted portions of the tongued line 26.
