Definitions

  • the present invention relates to a modular shoring tower for civil engineering and building, consisting of monoblock frames assembled together to form levels arranged to be superimposed, each level being composed of four monoblock frames mounted at right angles and defining a perimeter each one-piece frame being provided with at least one column segment, an upper horizontal rail and a diagonal bracing rail, each one-piece frame further comprising first locking means arranged to join two by two the adjacent monobloc frames of each level and second locking means arranged to join the two column segments of corresponding one-piece frames at two superimposed levels.
  • Shoring towers are mainly used to form slabs, floors, beams, etc. in order to carry out any type of concrete works or the like. They can also be used to work at height on certain works. They must therefore meet stringent technical requirements. To this end, the evolution of regulatory texts tends to improve the working conditions of operators as well in terms of safety, hardship, as ergonomics. Among these requirements, it is expected that the mounting of these shoring towers is done without tools and without dangerous maneuver, that the weight of the elements to be assembled is limited, that the operator located inside the tower of shoring can not accidentally fall during the assembly of the tower and that the assembled elements can not be disassembled randomly.
  • Conventional shoring towers are mounted level by level, like an element-by-element construction set, based on a generally four-foot jack-up base.
  • the first level is formed by nesting on the jack feet two ladders that face each other and linking them together by braces by means of bolts or the like.
  • One hooks a first platform between the two scales then one nests two other ladders with bars on the scales of the first level to form the second level, which one links between them by braces.
  • Guardrail tubes are added at the top end between the two ladders before continuing the assembly of the following levels, and so on. The assembly ends with the installation of railing panels on the last level.
  • the publication FR 2 939 464 which is considered as the closest state of the art and which discloses the features of the preamble of claim 1, proposes an improvement to the shoring towers by performing the successive levels by an assembly of monobloc frames incorporating locking means frames between them of the same level and levels superimposed, means of access to the platforms, as well as individual and collective security.
  • this solution makes it possible to reduce the number of elements to be assembled, to improve the assembly and disassembly operations of the shoring towers, to reduce the arduousness and to increase the safety of the operators.
  • the key system used for locking the monobloc frames of the same level requires the operator, positioned inside the tower, to rotate the first monobloc frame to the outside of the tower by a few degrees, that is to say outside the perimeter of internal security defined by the tower, to be able to assemble it with the last frame monoblock, this to avoid interference problems with the key system.
  • This constraint thus exposes the operator to the risk of an accidental fall.
  • this key system requires a tool such as a hammer or mallet to strike the key down to lock the horizontal assembly during assembly and to strike the key up to unlock it during the disassembly of the tower. This horizontal locking is essential to guarantee the rigidity and stability of the shoring tower.
  • a first action is to rotate the frame, to lock vertically to the frame of the corresponding lower level.
  • a second action is to hit the key, to lock the frame horizontally to an adjacent frame of the same level.
  • this second voluntary action is often forgotten because operators are not qualified and do not necessarily have a hammer at hand. The omission of this horizontal locking can have serious consequences, especially in the event of a collapse of the shoring tower and the construction it supports.
  • the present invention aims to overcome these disadvantages by providing a shoring tower provided with locking means designed and arranged differently to automatically lock and unlock the one-piece frames relative to each other during assembly and disassembly of the tower. shoring by a simple gesture, without any tooling or insert, ensuring optimum safety for the operator who is inside the tower while providing better ergonomics of work.
