[0003] In particular, the present invention finds preferred application in the anchoring industry industrially prefabricated structures intended for be assembled on site. 15

[0004] In the sector it is known, for example, to make a reinforced concrete building with assembly techniques of a plurality of building structures, for example industrially prefabricated. The structures can have a load-bearing function, such as vertical panels for 20 load-bearing walls, horizontal floor panels, structures for technological systems and also elements load-bearing prefabricated elements such as pillars, steel beams, plinths and arches; or they may be functionless load-bearing, such as stairways with or without parapets, 25 partitions, covered walls, walls prepared for electrical and plumbing systems, balconies and crownings.

[0005] In general, in the field of construction construction with assembly techniques, it is expected that construction of a concrete foundation on site. 5

[0006] The structures to be assembled are transported in construction site and moved to be anchored structurally to each other and structurally anchored to the building foundation, for example anchoring structures construction to the foundation tie rods. 10

[0007] The movement of the structures is carried out by means of cranes, which take care of the lifting and implementation by superposition, juxtaposition or mechanical coupling.

[0008] Once the operations are completed 15 alignment and anchoring, we continue with the works of completion and finishing of the building, such as waterproofing, flooring, painting, installation of fixtures and completion of systems electrical and plumbing. 20
