Adjustable system for embedded union of prefabricated concrete elements for building structures, and method for performing the union of prefabricated concrete elements

摘要

The present invention relates to an adjustable embedded joint system of prefabricated concrete elements for building structures and to a process to carry out said joint, wherein the adjustable joint system comprises at least two prefabricated reinforced concrete blocks, an upper prefabricated block and a lower prefabricated block that join vertically by means of a bushing that joins a steel reinforcing bar of the upper prefabricated block with a steel reinforcing bar of the lower prefabricated block connecting the two adjacent reinforced concrete blocks vertically, wherein the bushing comprises an upper surface that is in contact with the upper prefabricated block, wherein said bushing confers high rigidity to the whole upper prefabricated block and lower prefabricated block before carrying out the concreting of the joint area.
