Abstract: A clamp (51) for connecting panels in a surface coating structure on a base frame comprises a fixable element (100) and a rotatable element (200) having an upper part (220), projecting after its rotation from the fixable element (100) and provided with end (21, 22) of engagement in lateral grooves of adjacent panels. The rotatable element (200) has an intermediate part (280) and a lower part (290) which are constituted by two coaxial discs, the disc of the intermediate part (280) having a smaller diameter than the disc of the lower part (290). The fixable element (100) has two communicating coaxial holes (10, 11) housing the intermediate part (280) and the lower part (290) with a wide coupling to allow rotation of the rotatable element (200) with respect to the fixable element (100). A manufacturing process of the clamp (51) is also described.

Abstract: A leveling coating structure with quick installation and removal includes a plurality of parallel sections; a multiplicity of clips having a head with a stem and a bushing with inserts, the stem being inserted in a through hole of the section and rotatably retained by the inserts of the bushing which is in abutment with the bottom of the base frame opposite to the head of the clip; a succession of slats having opposite lateral grooves which the head of the clip engages. Each section is made of light alloy with a C-shaped cross-section having a core for supporting the slats and wings for the insertion of the bushings between them. Each clip is retained by the section with the head in abutment with the core for supporting the slats and the bushing in abutment with the free ends of the wings.

Abstract: A surface coating structure adapted to be quickly installed and removed includes a plurality of parallel sections (1), a multiplicity of connecting members (2) and of slats (3) which engage the connecting members (2). Each connecting member (2) is provided with a pair of mutually opposite central angled hooks (4, 4) and a pair of side angled hooks (5, 5). Each slat has an undercut side groove (10) formed in each longitudinal edge (11) of the slat (3) to engage a central angled hook (4) and a bottom prismatic groove (12) in a part opposite to a part in sight near each longitudinal edge (11) of the slat (3). Each bottom prismatic groove (12) has, with respect to the longitudinal edge (11), a proximal side (14) provided with a series of parallel knurls (17) adapted to retain the side angled hook (5) of the connecting member.
