• the invention relates to a joint arrangement for a surface structure, such as a protecting plate, element or a like, which surface structure is meant particularly for covering of ground together with one or several other surface structures for temporary protecting, coating and/or like of the ground.
• a joint arrangement for removable attachment of one or several adjacent surface structures to the same and a thermal insulation that comprises at least one, essentially plastic based, such as cellular, expanded, foamed plastic structured or a like thermal insulation layer.
• the joint arrangement comprises a joint piece, that is to be coupled by means of a locking assembly, for coupling of the adjacent surface structures with each other essentially by corners of the same, which joint piece comprises known as such a right-angled, such as a square shaped frame part, whereby the locking assembly is arranged by projections placed at the corners of the frame part and preferably by recesses of the same shape, that are placed underside the surface structure.
• an integral support arrangement that comprises a platform structure projecting from the basic wall thickness of the surface structure, such as the thermal insulation layer.
• the perforated structure of the covering element in question is naturally advantageous with a view to the breathing of the ground, but the ' perforation causes in addition to a "rough" appearance and to those thermal insulation problems being described above such disadvantage as well, that garbage may get collected between the covering and the ground, which naturally eliminates good points of the covering element in question in this respect.
• Finnish Patent Application No. 964199 discloses a protective structure, the thermal insulation of which comprises advantageously a plastic based, such as cellular, expanded, foamed plastic structured and/or a like thermal insulation layer, to the bottom surface of which there has been arranged an integral support arrangement, that comprises a platform structure projecting from the basic wall thickness of the thermal insulation layer particularly in order to achieve an air space between the protective structure and the ground under the same.
• a plastic based such as cellular, expanded, foamed plastic structured and/or a like thermal insulation layer
• the feet that are arranged as an integral platform structure directly to the bottom surface of the thermal insulation layer, prevent first of all so called burning of the grass that is left under the protective structure.
• an advantageous embodiment for coupling of the protective structures with each other by means of joint arrangements that are arranged to the protective structures in an integral manner during manufacturing of the same and that operate e.g. by quick-locking principle.
• joint arrangements that are arranged to the protective structures in an integral manner during manufacturing of the same and that operate e.g. by quick-locking principle.
• the protective structures could be on the other hand assembled as easily as possible but however locked in connection with each other reliably and seamlessly.
• application document DE 27 17 625 discloses a covering assembly, that is applicable for temporary covering of ground in principle, wherein three or four covering elements being placed on the ground are being attached by means of a joint piece coupling the covering elements together by the corners of the same and that has holding rings of suitable shape for arrowlike locking pins, that are placed at the corners of the covering elements.
• the joint pieces being used in this solutions are placed, however, essentially underneath the actual covering elements, that is why they must be sunk into the ground, that is why they are not applicable as such to be used in connection with the type of thin surface structures as being discussed in this connection.
• application document DE 25 58 967 discloses a base structure arrangement, that is to be put together e.g. by stone based elements, in which e.g.
• the joint arrangement according to this invention is primarily characterized in, that the frame part of the joint piece, that has an open center, such as a framework-like structure is arranged to pass the recesses existing in the platform structure, whereby the height of the recesses is arranged to correspond essentially at least to the thickness of the frame part.
• the joint piece has a square shaped framework, by means of which e.g. four surface structures may be connected with each other by means of one joint piece operating by quick-locking principle, e.g.
• the frame part of the joint piece is arranged furthermore to pass the recesses of the platform structure in a way, that the total thickness of the surface structure is not increased therefor.
• the covering structure may be coupled in an extremely simple way by continuously “dropping" the following surface structure to be installed from above to its place and by connecting the same to the already installed surface structures by means of joint pieces by corners of the same .
• Fig . 1 shows one advantageous surface structure related to the joint arrangement according to the invention
