But, can not be satisfactory from the Roof system that EP1489245 is known: it can not make roofing easily dismantle to carry out service intervention; It can cause moisture to infiltrate; And most important, it makes the aesthetic feeling at junction surface be confined to the contouring head of the rigid support at the junction surface of the curved side of support sheet panel.

Therefore, an object of the present invention is to provide and a kind of known Roof system is had to substituting Roof system, this Roof system can be dismantled and be assembled completely and easily, its profile aesthetic feeling is not limited to predetermined profile, and under any circumstance can guarantee that the sealing of good quality is with any infiltration of opposing moisture.

Summary of the invention

Therefore,, according to the present invention, at this, provide the metal sheet of setting forth as claim 1 Roof system.

Especially, according to the present invention, this Roof system comprises multiple panels, described multiple panel is made by metal sheet, and in use on the bearing of trend on the slope on described roof, arrange adjacent to each other, described in each, panel all has the first longitudinal sidepiece of himself, and described first longitudinal sidepiece is parallel to the bearing of trend on described slope and by using dismountable coupling device to be connected to relative second longitudinal sidepiece of next-door neighbour's panel.Coupling device comprises: first and second adjacent longitudinal sidepieces of every a pair of adjacent panel; At least one support, described at least one support is connected to described adjacent longitudinal sidepiece; And for described support being fastened to the fastener on the described slope on described roof.But, unlike the prior art, at least one support by described fastener with cantilevered fashion cross binding, thereby limit undercut portions towards described slope, and first and second at least one sidepiece in sidepiece manufacture can elastic deformation, so that utilize himself bonding part, at least multiple differences below described undercut portions (P1, P2 ..., Pn) locate, by snap action, engage described at least one support.In addition, the first and second adjacent side of every a pair of adjacent panel have complementary contours, and below described undercut portions in mutual overlapping mode, at least at position and the support of the bonding part corresponding to snap action, be linked together.

Preferably, dismountable coupling device for every pair of adjacent sidepiece to be connected comprises multiple supports, the plurality of support is engaged by least one in the described first and second adjacent sidepieces of the panel adjacent with every pair by snap action at above-mentioned multiple somes place, so that prevent from must having the support of the length that the length of extending with longitudinal sidepiece to be joined is identical on the bearing of trend on the slope on roof, and each support is in different some places.

In addition, according to other feature of the present invention, each support has fastening part for being fastened to described slope and for clamping the clamping part of described the first and second sidepieces of described panel, described clamping part has the recessed profile towards described slope, and with cantilevered fashion, from described fastening part, extends in the direction of the first and second sidepieces perpendicular to described panel.First longitudinal sidepiece of each panel limits by being folded to form L shaped edge part, described edge part is with on the relative sidepiece on described slope, described edge part in use can insert in the described cavity of described clamping part, and second longitudinal sidepiece of each panel is defined by box section portion, box section portion is open on the sidepiece towards slope and be formed so that limit longitudinal housing in use, and described longitudinal housing design becomes therein side and comprises each support being mated.
