Definitions

  • This document describes a claw for crosspiece to be used in the crosspiece setting in mobile working towers made of pre-fabricated elements (modular system).
  • the simple rabbet systems (a) are easy to assemble, can be slightly trusted, work only by pressure rabbet, but can be freed easily by accidental actions or by verified movements/vibrations in the towers during the works.
  • the setting methods referred in (b) and (c), of the anterior paragraph have as main inconvenience the assembly and dissemble problem, which is complicated and delayed, because, besides the cramps, wedges or rods, it is necessary other accessories for the assembly, such as (screws, nuts, etc.), which also involves using squeezing and relief tools.
  • the assembly and dissemble of these towers have inevitable man power costs associated to the necessity of assembly/dissemble other braking elements.
  • This new claw for crosspiece resolves totally all the anterior referred problems, because since its elements were technically studied, with optimised configuration and functioning, it allows an easy, rapid, resistant and safe assembly, dismount and reconfiguration of the mobile working towers made of pre-fabricated elements, easily adapted to modular systems.
  • This claw for crosspiece is introduced in the extremities of the crosspiece and fixed with a rivet, all being part of the crosspiece set, including the profile and the claws.
  • the geometric configuration of the Claw body for the Crosspiece is easily adapted to be equal to the profile periphery used in the crosspiece and in the mobile working towers elements build with pre-fabricated elements. The following profiles are dependent of the used geometrical configuration:
  • the setting of the claw presents characteristics for the working towers installation placed outside, exposed to the environment conditions (atmospheric agents, polluting agents, etc.).
  • the claw for the crosspiece presents itself with two differentiated safety elements, the Automotive Mobile Element (3) and the Safety Latch (2). Both were studied with the main purpose to restrict unnecessary access, to control and to prevent accidental actions in the structure crosspiece setting system. Only the movements of these two elements permit alternating between the "open” positions, for the assembly, and the "close” positions, for situations of concluded assembly.
  • the opening of the automotive latch system (3) is influenced by two buttons simultaneously (5). With simple and rapid actions and without the use of complementary accessories, the crosspiece is assembled in the structure and fixed with high security.
  • the Mobile Automotive Element (3) moves in rotation around an axle (6); the buttons (5) are fixed by an elastic peg (7 fig. 6) and the cradle for the spring (8 fig. 6) has as main function the movement that blocks and unblocks, allowing the open and close positions.
  • the Safety Latch (2 fig. 6) comprises a spring (10 fig. 6) and a guide bolt (11) that helps the element to maintain its opening and closing positions.
  • This Security lock is fixed by forging elements, since the ring function (9) and the bearing function (12) permits forging the Latch without its immobilization, in other words, they permit the rotation movements.
