Definitions

  • the present invention refers, in general, to a building system for the construction industry. More particularly, the present invention refers to a system for coupling one or more beams to a pillar, which converge to a point called "wet knot" as formed by a completion jet that solidarizes the various elements so as to form a single body, which is typical of the civil structures in work.
  • prefabricated structures are used to speed up the construction of said buildings and reduce the costs of construction.
  • the prior art For the coupling of beams to pillars by means of prefabricated structures, the prior art involves placing beams on shelves that are obtained on pillars; in other terms, the ends of the beams rest on shelves that are provided on the pillars.
  • the cementitious material is cast so as to obtain a single body.
  • An aim of the present invention is to remove the above mentioned disadvantages and others by carrying out a construction system that is practical and fast through the use of prestressed structures, and also applicable in the construction of civil buildings and not only industrial buildings.
  • Another aim of the present invention is to carry out a construction system in order to obtain an aesthetically pleasant coupling of one or more beams to a pillar.
  • Another aim of the present invention is to carry out a construction system that is safe not only when the construction is finished, but also during the phases of construction of the building.
  • WO 2006/004414 A1 discloses a building system with the features of the preamble of claim 1.
  • the building system according to the invention provides that once the one or more beams have been fixed to the pillar, a cementitious material is cast on the coupling of the one or more beams to the pillar so that the structure is made solid.
  • the building system according to the invention involves the coupling of one or more prefabricated beams to a pillar preliminarily by means of a mechanical connection without the need to have a shelf on the pillar for the support of the beams, and subsequently by means of a solidarization of said coupling with a completion jet so as to simulate the same static behavior of the structures in work by using prefabricated elements.
  • this system allows to obtain all the advantages of the prefabrication as concerns the realization of the elements and the assembly, as well as all the advantages of the buildings in work, once the "wet knot", typical of the structures in work, has been completed.
  • the at least one beam comprises a first longitudinal portion and a second longitudinal portion, wherein the first longitudinal portion is disposed under the second longitudinal portion; the at least one retractable shelf being comprised at the end of the second longitudinal portion; at least one bar with threaded free end being comprised along the second longitudinal portion so as to fix a connecting bar by screwing it in said at least one bar for the connection with at least one further beam.
  • the building system according to the invention may provide that the seat obtained in the one or more supports comprises a tooth and that the internal sliding element comprises a blade in which at least one recess is formed so that once the blade has been received in the seat, the blade is locked in position by means of the tooth inserted in the recess.
  • This fixing method allows that the blade may not move unintentionally and consequently, the coupling is made even safer.
  • the one or more supports may comprise a C-shaped plaque having a horizontal lower portion, a horizontal upper portion and a vertical lateral portion in which a through opening is forme.
  • a continuity bar may be connected with an end to a connecting bar of a first beam and with the opposite end to a connecting bar of a second beam.
  • the building system according to the invention allows to have not only a connection between beam and pillar, but also between beams joined to the pillar in the same knot.
  • a housing above the first longitudinal portion, in continuity with the second longitudinal portion in order to facilitate the casting of cementitious material on the knot formed by the pillar and the one or more beams.
  • first longitudinal portion may be disposed laterally to the second longitudinal portion in order to reduce the height of the beam, in particular for civil appations, according to a non claimed embodiment.
  • the building system according to the invention may provide also that in at least one beam, at least one seat is obtained laterally to receive an end of a joist for floor.
  • At least one end of the joist may comprise an extensible element comprising a movable bracket adapted to go out of the extensible element to rest on a seat of the one or more beams.

  • Both the first beam 514 and the second beam 516 receive, at their end, two retractable shelves 550 shaped like the retractable shelves 450 and adapted to be inserted in the supports of the pillar through the more internal parallelepiped element.
  • Wooden beams 554 are fixed through S-shaped brackets 552 to the lower portion 542 of the first beam 514 and second beam 516 in order to carry out a wooden floor.
  • An S-shaped bracket 552 is illustrated individually in figure 66 .
  • the building system according to the invention enables to utilize prefabricated elements in order to make the realization of the structure practical and rapid.
  • the couplings obtained by means of pillar housings, beam housings and extensible elements allow to have safe, stable connections which become even more secure once the filling casting has been accomplished.
  • the fixing of the continuity bars between different beams allows to obtain a structure tied up continuously and consequently, to obtain a more stable structure.
  • the building system according to the invention allows to avoid the utilization of shelves, the resulting aesthetic appearance being thus more pleasant.
  • the building system according to the invention offers also the possibility of utilizing more valuable materials than concrete, such as wood.
  • a technician of this sector may conceive changes or variants that are to be considered as included in the scope of protection of the present invention.
  • the coupling between beams and pillar may be reversed, namely, a bracket may go out of a housing arranged in the pillar, which bracket is inserted in a hollow housing disposed in the beams.
