Abstract

A system for forming an anchorage configured to fasten the lower legs of a vertical mast of a crane to an upper face of a concrete foundation mass includes a plurality of casting bases, each with a lower plate to be embedded into the foundation mass and connecting sleeves connected to the lower plate and encased into the foundation mass. A geometric adjustment device removably interconnects the casting bases with each other with a plurality of upper plates contacting the connecting sleeves. Each connecting sleeve internally delimits an isolated pocket. Anchoring bars, each screwed onto a lower plate and extending over an upper plate to protrude above the upper face of the foundation mass, removably extend into the pockets delimited by the connecting sleeves. Clamping elements create a load from the upper plates to the lower plates so as to clamp the connecting sleeves.

Dependent claims

A system for forming an anchorage configured to fasten the lower legs of a vertical mast of a crane to an upper face of a concrete foundation mass, the system comprising:

a plurality of casting bases wherein a number of casting bases is greater than or equal to 3, each of the casting bases comprising:
a lower plate intended to be embedded into the foundation mass;
and
a plurality of connecting sleeves extending from the lower plate and intended to be at least partially encased into the foundation mass;
a geometric adjustment device, interconnecting in a removable manner the casting bases with each other, intended to be arranged above the upper face of the foundation mass and comprising a plurality of upper plates, each upper plate being associated with one of the casting bases and being positioned in contact with the connecting sleeves of the casting base which is associated with it, so that, for each casting base, the connecting sleeves connect the upper plate and the lower plate and each connecting sleeve internally delimits a pocket intended to be isolated from the foundation mass;
a plurality of anchoring bars having a first end fastened by screwing to the lower plate of one of the casting bases and a second end extending above the upper plate on a side opposite the lower plate and intended to protrude above the upper face of the foundation mass, each anchoring bar extending along one of the pockets delimited by the connecting sleeves in a manner removable from the connecting sleeve which surrounds it;
and
a plurality of clamping elements screwed onto the second ends of the anchoring bars and each intended to create, at one of the casting bases, a load from the upper plate toward the lower plate so as to clamp the connecting sleeves.

5 more elements

A method for forming an anchorage making it possible to fasten the lower legs of a vertical mast of a crane to an upper face of a concrete foundation mass, the method including the steps of:

implementing a system such that casting bases of the system rest on a fixed ground within a terrestrial reference frame, wherein the system comprises
a plurality of casting bases wherein a number of casting bases is greater than or equal to 3, each of the casting bases comprising
a lower plate intended to be embedded into the foundation mass;
and
a plurality of connecting sleeves extending from the lower plate and intended to be at least partially encased into the foundation mass;
a geometric adjustment device, interconnecting in a removable manner the casting bases with each other, intended to be arranged above the upper face of the foundation mass and comprising a plurality of upper plates, each upper plate being associated with one of the casting bases and being positioned in contact with the connecting sleeves of the casting base which is associated with it, so that, for each casting base, the connecting sleeves connect the upper plate and the lower plate and each connecting sleeve internally delimits a pocket intended to be isolated from the foundation mass;
a plurality of anchoring bars having a first end fastened by screwing to the lower plate of one of the casting bases and a second end extending above the upper plate on a side opposite the lower plate and intended to protrude above the upper face of the foundation mass, each anchoring bar extending along one of the pockets delimited by the connecting sleeves in a manner removable from the connecting sleeve which surrounds it;
a plurality of clamping element screwed onto the second ends of the anchoring bars and each intended to create, at one of the casting bases, a load from the upper plate toward the lower plate so as to clamp the connecting sleeves;
carrying out the foundation mass by pouring and curing a quantity of concrete, in such a way that the geometric adjustment device of the system is arranged above the upper face of the foundation mass;
and
removing the geometric adjustment device from the casting bases in order to allow the vertical mast of the crane to be fastened, due to the clamping elements, the anchoring bars of the system and the foundation mass.

8 more elements

A method for fastening the lower legs of a vertical mast of a crane to an upper face of a concrete foundation mass, comprising:

implementing a first phase comprising implementing a system such that casting bases of the system rest on a fixed ground within a terrestrial reference frame, wherein the system comprises
a plurality of casting bases wherein a number of casting bases is greater than or equal to 3, each of the casting bases comprising
a lower plate intended to be embedded into the foundation mass;
and
a plurality of connecting sleeves extending from the lower plate and intended to be at least partially encased into the foundation mass;
a geometric adjustment device, interconnecting in a removable manner the casting bases with each other, intended to be arranged above the upper face of the foundation mass and comprising a plurality of upper plates, each upper plate being associated with one of the casting bases and being positioned in contact with the connecting sleeves of the casting base which is associated with it, so that, for each casting base, the connecting sleeves connect the upper plate and the lower plate and each connecting sleeve internally delimits a pocket intended to be isolated from the foundation mass;
a plurality of anchoring bars having a first end fastened by screwing to the lower plate of one of the casting bases and a second end extending above the upper plate on a side opposite the lower plate and intended to protrude above the upper face of the foundation mass, each anchoring bar extending along one of the pockets delimited by the connecting sleeves in a manner removable from the connecting sleeve which surrounds it;
and
a plurality of clamping element screwed onto the second ends of the anchoring bars and each intended to create, at one of the casting bases, a load from the upper plate toward the lower plate so as to clamp the connecting sleeves;
the first phase further comprising carrying out the foundation mass by pouring and curing a quantity of concrete in such a way that a geometric adjustment device of the system is arranged above the upper face of the foundation mass;
implementing a second phase comprising removably fastening each of the lower legs secured to said vertical mast, by screwing each of the clamping elements onto the second end of one of the anchoring bars to clamp, at each casting base, one of the lower legs between the clamping element and the upper face of the foundation mass;
and
implementing a third phase comprising removing the anchoring bars by unscrewing them from the lower plates and sliding them upward relative to the connecting sleeves.
