Modular shoring tower for civil engineering and construction

摘要

Shoring tower (1) modular for civil engineering and construction, comprising monoblock frames (6) assembled together to form levels (2) arranged to be superposed, each level consisting of four monoblock frames (6) mounted on right angle and defining a security perimeter (P), each monoblock frame provided with at least a segment of the post (40), a horizontal top bar (61) and a diagonal bar fastening (63) being, comprising besides each frame monobloc a first locking means (8) arranged so as to secure two at adjacent monoblock frames (6) of each level (2) and second locking means (9) arranged so as to secure two by two segments pole (40) corresponding to two levels (2) superposed, characterized in that said first locking means (8) of each monobloc frame (6) comprise, monoblock frames (6) a portion, at least one pin detent (80, 800) of axis extending radially from the upper end (41) of the segment post (40) parallel to the upper horizontal bar (61), said pawl being ( 82, 820) mounted to pivot on said pin (80, 800) and forming a latch, and, moreover, a through hole (81, 810) of axis B complementary to said pin detent (80, 800 ) and arranged at the free end of said upper horizontal bar (61), and that said axes a and B are perpendicular to each other and are comprised in the same horizontal plane so that said pin detent (80, 800) and said corresponding to two monoblock frames (6) adjacent to assemble through hole (81, 810) are fitted for movement horizontal pivot (R) of one of the monoblock frames relative to each other about a pivot axis (C) defined by post segment (40), registering said Stroke to pivot (R) in the security perimeter (P) and said pawl (82, 820) arranged to lock said pin detent (80, 800) at the rear of said through hole (81, 810) this being security perimeter (P).
