Sets of modular raceways for structured optical-fiber cabling

A set of modular beds, comprising:

• a plurality of beds (10), each of beds (10) comprising a bed module (20) capable of receiving, through lateral coupling, at least one crossbar-type module (30) or at least one T-branch module (40);
• a 45° curve module (50) and a 90° curve module (60) which are coupled to the sides of two bed modules (20) whose ends are juxtaposed through complementary angulation;
• a 90° to 45° descent module (70) and a 90° to 45° ascent module (80) capable of coupling to the distal end of at least one bed module (20);
• a left reduction module (90) comprising coupling means at the distal end of at least one module (20);
• a nozzle-type module (110) and a splice-type module (111) arranged as a coupling between two bed modules (20);
• a drip module (112) comprising an attachable accessory as the final end of a bed module (20);
• characterized by the modules (20), (30), (40), (50), (60), (70), (80), (90), (110), (111), and (112) that compose the set of beds (10) being capable of expansion in both length and width and comprising at least one central profile (11) with pairs of longitudinal connections (CL1) and (CL2) for coupling to end profiles (13), each with corresponding base connections (CL1) and (CL2);
• the longitudinal connection (CL1) corresponds to connection (CL2), which is formed by an engagement member (10a) with an inverted L-shaped section and provided with a longitudinal recess (10b) that forms a step for the edge of the central profile (11) to be assembled, while the connection (CL2) is formed by a locking member (10c) with a J-shaped cross-section, whose flat portion (10c′) has a greater width (L2) compared to the width (L3) of the flat portion (10a″) of part of the engagement member (10a) and features an orthogonal end (10) with increased thickness (e1) to form a locking tooth (dt) for engaging the flat portion (10a);
• the central profile (11) comprises a plate (11a) with widths (11) and extreme straight edges (11b), chamfered (11b′), in an inverted V-shape (11b), and also features a central V-shaped cutout (11c);
• said central profile (11) provides that the extreme lateral edges are formed by complementary longitudinal connections (CL1) and (CL2) for the assembly of end profiles (13);
• between the complementary longitudinal connections (CL1) and (CL2) of each central profile (11), L-section walls (11d) protrude to form gaps (v1).
