Definitions

  • the present invention relates to a structure for covering surfaces.
  • the structure finds useful but not exclusive application in the field of construction for covering roofs and walls.
  • roofing structures for covering surfaces which meet criteria such as mechanical stability, waterproofing, ease of installation and aesthetics.
  • slab-like elements or panels is known, especially in metallic material, arranged adjacent to each other and anchored to a load-bearing structure.
  • such panels typically have two complementary coupling portions, arranged on opposite sides and extending parallel for the entire panel extension.
  • Each coupling portion is configured to be stably couplable with the coupling portion of an adjacent panel.
  • the combination between two coupling portions essentially provides that one of the two coupling portions is such as to be housed at least partially within the other.
  • a fixing bracket is typically used which is configured to retain an end edge of the inner coupling portion.
  • the coupling of the coupling portions is not sufficiently airtight to prevent the passage of water, especially in the event of heavy rainfall or if the rainwater disposal system is insufficient.
  • these types of panels have recesses on the lower coupling portion, extending throughout the length of the panel, configured to collect and channel the filtered rainwater between the two coupling portions.
  • a further major drawback is the complexity in the assembly steps of the known coverage systems. This complexity is essentially derived from the need to manually handle large panels which must be correctly coupled to each other and to the support bracket, under penalty of the formation of water passage slots and the progressive detachment of the coupling portions.
  • Document JP H09 111 962 A discloses a covering structure according to the preamble of claim 1.
  • the technical task underpinning the present invention is to provide a covering for surfaces which obviates at least some of the drawbacks in the prior art as described above.
  • an object of the present invention is to provide a structure for covering surfaces able to guarantee a better anchorage to the load-bearing structure.

  • the first and second portions 6 and 7 define the panel portions adapted to be constrained to a load-bearing structure by means of the fixing bracket 4 and the anchoring bracket 5.
  • the first coupling portion 6 is projecting from the main portion 8, i.e., it extends away from the longitudinal plane "S" on which the main portion 8 lies.
  • the first coupling portion 6 has a complex and at least partially shaped profile.
  • the first coupling portion 6 has a head part 9 and a base part 10, which connects the head part 9 to the main portion 8.
  • the base part 10 has two walls 10a and 10b each having a substantially upward profile approaching the head part 9.

  • the temporary housing defined by the head part 12 of the second coupling portion 7, then allows the first coupling portion 6 of the first panel 2 to be correctly aligned with the second coupling portion 7 of the second panel 3.
  • the application of a force pushing the second coupling portion 7 towards the first coupling portion 6 causes the head part 12 of the second coupling portion 7 to be stressed to expand elastically to allow the insertion of the first coupling portion 6 of the first panel 2.
  • the panels 2 and 3 are anchored to the load-bearing structure by means of anchoring bracket 5 and fixing bracket 4.
  • This combined action of the brackets 4, 5 is able to withstand very high stresses caused for example by violent atmospheric agents.
  • the first panel 2 has an end relief 16 arranged adjacent to the first coupling portion 6.

  • the fixing bracket 4 also has a connecting portion 19, integral with the coupling portion 18, and seamless with the coupling portion 18. It should be noted that the two portions 18, 19 are made of a single sheet obtained by bending.
  • the connecting portion 19 is stably connectable to the anchoring bracket 5.

  • the anchoring bracket 5 is made of a monolithic body, preferably but not limited to polyamide or acetyl resin.
  • the cavity 20 is formed in the anchoring bracket 5 in a decentralized lateral position, and defines an access opening 22 of the fixing bracket 4.

  • the support element 25 has a tapered shape away from the lower surface of the anchoring bracket 5 and has projections 25a, 25b defining respective section enlargements to engage with at least one undercut 11 or 14 of the first or second coupling portion 6 or 7.
  • the structure 1 appears to have a higher mechanical resistance to external stresses.

  • each panel 2 and 3 has a first and a second lower protrusion 27, preferably each defining a shaped groove, arranged near the first and second coupling portions 6 and 7, respectively.
  • first and second lower protrusions 27 are oriented in non-parallel directions to each other.
  • Such lower protrusions 27 are shaped so as to be housed in a shape-coupling in the pair of recesses 26 obtained in the anchoring bracket 5.
  • the shape-coupling between the lower protrusions 27 and the pair of recesses 26 improves the mechanical stability of the structure 1 and the stability of the anchoring.
  • the pair of recesses 26, and consequently the respective protrusions 27, have a width at least one third greater than the state of the art, in order to simplify assembly operations.
  • the ease of assembly is improved by obtaining protrusions 27 which act as natural springs so that the insertion is facilitated without straining or deforming the metal sheets.
  • the assembly is facilitated by the two sheet portions of concave curvature interposed between the protrusions 27 and the undercuts 11 and 14. Such portions perform the spring function and, during assembly, allow the portions 6, 7 to be pushed into support against the projections 25b, sufficiently so that the protrusions 27 can "slide” with a downwards thrust into the recesses 26, without undue effort.
  • the natural positioning of the sheet portions 6, 7 inside the anchoring bracket 5 ensures that the panels are retained extremely effectively by the characteristic elements of the system (18, 18a, 18b, 25, 25a, 25b, 27). Furthermore, the greater width facilitates the sliding of the sheet on the plastic bracket due to natural thermal expansion, also guaranteeing less system noise as the slab has less constriction, reducing friction which causes noise, especially at high temperatures.
  • the present invention attains the set aims, overcoming the lamented drawbacks of the prior art and providing a structure for covering surfaces capable of ensuring better anchorage to the load-bearing structure.
  • the presence of the anchoring bracket 4 allows to maintain the panelling in a correct arrangement, in particular the first and second panels, in the event of stresses due to, for example, atmospheric agents.
  • the combined work of the anchoring bracket and fixing bracket allows a robust anchoring of the panel to the load-bearing structure.
  • the joint action of the brackets provides a greater number of anchorage points and thus a better distribution of stresses.
  • the shape-anchorage between the anchoring bracket and coupling portions causes the stresses not to be concentrated on the fixing bracket and consequently on the connection means which secure it to the load-bearing structure.
  • Another object attained is that of providing a structure for covering surfaces capable of ensuring a better mechanical response to external stresses, avoiding premature breakage of the panel and undesired movements of the same.
  • the presence of the anchoring bracket allows to maintain the panelling in a correct arrangement, in particular the first and second panels, in the event of stresses due to, for example, atmospheric agents.
  • the shape anchoring between the coupling portions and the anchoring bracket allows for effective stabilization of the panels.
  • the structure is able to provide a more robust anchorage.
  • a further object achieved is that of providing a structure for covering surfaces which can guarantee a better seal of the panelling.
  • the coupling portions are combined in a cohesive manner ensuring an airtight seal which prevents water from filtering.
  • the infiltration collection channel defined by the end portion 17 represents the draining joint of the system.
  • This channel is particularly wide in terms of water flow with a vertical extension which guarantees greater safety than any water flow therefrom.
  • the collection channel is centrally positioned and raised with respect to the reference laying planes of the sheets, i.e., where the rainwater flows. This difference in height increases safety in the event of possible water infiltration.
