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. ## Claims ### Claim 1 A leveling coating structure (1) with quick installation and removal comprising: a plurality of parallel sections (2) forming a base frame with its bottom on a supporting plane (V), each section (2) being provided with a multiplicity of through holes (6); a multiplicity of clamps or clips (3; 301), each clip (3; 301) having a head (25; 250) with a stem (26; 260) and a bushing (27; 270) with inserts (28; 280), the stem (26; 260), which is orthogonal to the head (25; 250), being inserted in a through hole (6) of the section (2) of the base frame and rotatably retained by inserts (28; 280) in the bushing (27; 270) which is in abutment with the bottom of the base frame opposite to the head (25; 250) of the clip (3; 301); and a succession of slats (4) arranged on the parallel sections (2) of the base frame at right angles thereto, to form a coating, each of the slats (4) having opposite lateral grooves (40) which the head (25; 250) of the clip (3; 301) engages; each section (2) being made of an alloy with a C-shaped cross-section having a core (5) for supporting the slats (4) in which the multiplicity of through holes (6) are formed, and wings (7, 8) mutually spaced apart for the insertion of the bushings (27; 270) between them, wherein the wings (7, 8) end at the bottom with U-inverted supporting feet (14, 15), a supporting foot (14) extending with a portion (16) perpendicular to the inside of the section (2) and with an L-shaped angular portion (17) towards the outside of the section (2), the other supporting foot (15) extending with a first portion (18) perpendicular to the inside of the section (2) and with a second portion (19) perpendicular to the outside prosecuting in a third portion (20) perpendicular upward, to allow the side by side interlock of a section (2) with another. ### Claim 2 (depends on 1) The structure according to claim 1, wherein each clip (3; 301) is retained by the section (2) with the head (25; 250) in abutment with the core (5) for supporting the slats (4) and the bushing (27; 270) in abutment with free ends of the wings (7, 8). ### Claim 3 (depends on 1) The structure according to claim 1, wherein the core (5) of the section (2) has a swallowed central portion (9) in which the through holes (6) are formed. ### Claim 4 (depends on 1) The structure according to claim 1, wherein the wings (7, 8) of the section (2) have facing C-shaped recesses (10, 11) for application to the section (2) of an end plug (13) by means of screws (12) inserted in such C-shaped recesses (10, 11). ### Claim 5 (depends on 1) The structure according to claim 1, wherein a Z-shaped abutment element (21) has a lower portion (22) for fixing with screws on the outer surface of the core (5) of the section (2) and an upper portion (24) adapted to be inserted in the side groove (40) of a slat (4) for retaining a terminal slat of the coating. ### Claim 6 (depends on 1) The structure according to claim 1, wherein the head (25; 250) of the clip (3; 301) is prismatic with a rectangular plan that is beveled in opposite vertices (31) to allow a rotation of the head (25; 250) of the clip (3; 301) of only 90 degrees in the engagement with the lateral groove (40) of the slat (4). ### Claim 7 (depends on 6) The structure according to claim 6, wherein the head (25; 250) of the clip (3; 301) is provided with a downwards facing projection (34) showing its position. ### Claim 8 (depends on 1) The structure according to claim 1, in which the stem (26) of the head (25) of the clip (3) is pierced with a central hole (35) in which a stud (36) projecting upward integrally with the bushing (27) is inserted. ### Claim 9 (depends on 1) The structure according to claim 1, wherein the head (25; 250) of the clip (3; 301) is provided with a first hexagonal hole (33) for engagement with a first hexagonal male key (CH1) for the rotation of the head (25; 250) of the clip (3; 301). ### Claim 10 (depends on 1) The structure according to claim 1, wherein the bushing (270) of the clip (301) houses an upward projecting pin (360), that is drilled and internally threaded, and the base (300) of the bushing (270) is perforated with a hole (39) for the passage of a threaded pin (38) combined with a foot (37) and adapted to engage said projecting pin (360). ### Claim 11 (depends on 10) The structure according to claim 10, wherein said threaded pin (38) with a foot (37) has a second hexagonal hole (42) for engagement with a second hexagonal male key (CH2) for adjusting the height of the base frame with respect to the foot (37).
