Abstract
A novel support system is disclosed for supporting pipes conducting fluid in service galleries, particularly in the chemical, petrochemical or nuclear industry. The support system includes at least one pre-assembled, movable portal frame including metal tubes welded together and set out as a main framework and rungs intended to support said pipes having a horizontal or inclined longitudinal axis. After moving the support system to a service gallery, an anchoring structure is used to anchor the pre-assembled, movable portal frame to structural works in the service gallery.
Claims40
A support system for supporting pipes comprising:
- at least one pre-assembled, installable portal frame including metal tubes with circular cross-section welded together and set out as a main framework and rungs for supporting pipes having a horizontal or inclined longitudinal axis;
- and
- an anchoring structure secured to the main framework of said portal frame, said anchoring structure being constructed and arranged to anchor said pre-assembled, installable portal frame to structural works in a service gallery and to spread a load of said portal frame and said pipes over a concrete structure of said structural works,
- said anchoring structure comprising mounting plates comprising at least one series of positioning marks, a distance between centers of said positioning marks of said series allowing at least one stud to be fitted through one of said positioning marks of said series or at the center of said series, each of said series of positioning marks comprising four positioning marks arranged at four corners of a square having its side longer than a diameter of a reinforcing bar included in the structural works and shorter than a distance between two of said reinforcing bars.
