Definitions

  • 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 joining.
  • the object of the invention consists of an adjustable embedded joint system of prefabricated concrete elements for building structures that comprises at least two blocks of prefabricated reinforced concrete, an upper prefabricated block and a lower prefabricated block that join vertically by means of a bushing that connects a steel reinforcing bar of the upper prefabricated block with a steel reinforcing bar of the lower prefabricated block supporting the two adjacent reinforced concrete blocks vertically.
  • the bushing comprises an upper surface that is in contact with the upper prefabricated block, so that it facilitates the joining between the upper prefabricated block and the lower prefabricated block, and said bushing confers high rigidity to the whole upper prefabricated block and lower prefabricated block before carrying out the concreting of the joint area.
  • Joint systems among elements of prefabricated concrete are also known as the one described in the Japanese patent JP3212537A that uses a solid bushing to carry out the threaded joint to the upper and lower bars of a prefabricated upper and lower block respectively in an intermediate area among said blocks.
  • the previous system has the disadvantages of being hard to assemble as well as the risk of breakage before the concreting of the framework between both blocks, because the bars are the ones that bear all the stress up to the framework concreting phase.
  • the present invention relates to an adjustable embedded joint system of prefabricated concrete elements for building structures which comprises at least two prefabricated reinforced concrete blocks, an upper prefabricated block and a lower prefabricated block, or an upper prefabricated block and the foundation of the structure that are joined vertically through some upper and lower reinforcing bars that protrude from the lower prefabricated block or foundation, and from the upper prefabricated block respectively,
  • the adjustable joint system comprises at least a bushing that joins a reinforcing bar of the upper prefabricated block with a reinforcing bar of the lower prefabricated block or the foundation connecting the two adjacent reinforced concrete blocks or the upper prefabricated block and the foundation.
  • the bushing comprises an upper surface that is in contact with the upper prefabricated block, so that it facilitates the joining between the upper prefabricated block and the lower prefabricated block or foundation, and said bushing confers high rigidity to the whole upper prefabricated block and lower/foundation prefabricated block before carrying out the concreting of the joint area.
  • the bushing is of a high rigidity material, such as steel, so that the adjustable joint system is capable of bearing traction and compression stress once the joint has been concreted, since the elastic limit isn't reached at any point of the bushing, and stress due to the own weight of the upper prefabricated block and to extreme wind stress before the concreting, since no tension higher than the breakage one is reached at any point of the bushing.
  • the bushing is formed by a polygonal pipe section that comprises an upper side that is the upper surface that is found in contact with the upper prefabricated block and a lower side. Both the upper side and the lower side have holes for the passage of a reinforcing bar of the upper prefabricated block and lower prefabricated block or foundation respectively.
  • Both the upper bars and the lower bars have a threaded end to allow the coupling of some bolts, where the joint system comprises a first bolt inwardly adjacent to the upper side of the bushing, first bolt that carries out the joining of the bushing to the upper prefabricated block , and a second bolt outwardly adjacent to the lower side of the bushing, second bolt that bears the weight of the upper prefabricated block and allows performing the adjustment of the joint, by varying the distance between the upper prefabricated block and the lower prefabricated block or foundation.
  • the joint system also comprises a third bolt inwardly adjacent to the lower side of the bushing, a third bolt that prevents the vertical movement of the upper prefabricated block.
  • the joint system thus formed besides the aforementioned advantages, allows the bushings to remain embedded in the concrete that penetrates in the interior thereof when concreting the joint this way bracing its walls and increasing even more if possible the rigidity in the joint.
  • the process for carrying out the joining of elements of prefabricated concrete comprises the following steps:
  • the adjustable joint system is carried out between two prefabricated reinforced concrete blocks, an upper prefabricated block (7) and a lower prefabricated block (1) that join vertically.
  • an upper prefabricated block and a lower prefabricated block instead of carrying out the joining between an upper prefabricated block and a lower prefabricated block, the joining between the foundation and an upper prefabricated block is performed.
  • the adjustable joint system comprises at least a steel bushing (4) that joins a steel bar (5) of the upper prefabricated block (7) with a steel bar (2) of the lower prefabricated block (1).
  • the bushing (4) is formed by a rectangular steel pipe section that includes an upper side (9) which is in contact with the upper prefabricated block (7), a lower side (10) and two vertical sides (13). Both the upper side (9) and the lower side (10) have holes (11) for the passage of a steel bar (5, 2) of the upper prefabricated block (7) and the lower prefabricated block (1) respectively.
  • Both the upper steel bars (5) and the lower steel bars (2) have their ends (12) threaded to allow coupling some bolts (3, 6, 8) arranged in the following way:
  • All the bushings (4) are located within the outer perimeter in plan of the prefabricated block section (1, 7) so that they are not seen when the joined blocks are part of side or edge elements of the structure.
  • Figures 1 and 3 show that the prefabricated blocks (1, 7) have the same section, but by means of the adjustable joint system of the present invention the joining of prefabricated blocks (1, 7) of a different section can be carried out, where all the bushings (4) fall within the projection in plan of the prefabricated block (7) with the smaller section and where the prefabricated block (7) with the smaller section is manufactured at a certain length that is greater than the theoretical one to ensure that the lower face of the prefabricated element (7) with the smaller section falls below the theoretical line of the framework so as to ensure the total continuity of the concrete by making sure that the compressions will be transmitted throughout the area of said concrete
  • the process for carrying out the adjustable joint system comprises the following steps:
