Definitions

  • the invention relates to method for mounting a prefabricated construction element comprising concrete to another construction element as defined in the preamble of independent claim 1.
  • the invention also relates to a connection arrangement between prefabricated construction element comprising concrete and another construction element as defined in the preamble of independent claim 9
  • Document ITVR 20 100 206 A1 discloses a method according to the preamble of claim 1 and a connection arrangement according to the preamble of claim 9.
  • the object is to provide a method for mounting a prefabricated construction element comprising concrete to another construction element and a connection arrangement between prefabricated construction element comprising concrete and another construction element, which allows to open the connection between the prefabricated construction and the another construction element in such manner that the prefabricated construction element comprising concrete can easily be demounted and be reused so as to promote circular economy.
  • connection arrangement between prefabricated construction element comprising concrete and another construction element of the invention is correspondingly characterized by the definitions of independent claim 9 .
  • the prefabricated construction element comprising concrete can for example be any one of a prefabricated reinforced concrete column/pile/pillar, a prefabricated reinforced concrete beam and a prefabricated concrete wall element.
  • Said another construction element can also be a prefabricated construction element comprising concrete for example a prefabricated reinforced concrete column/pile/pillar.
  • said another construction element can be a cast-in-situ construction element comprising concrete such as a reinforced concrete foundation or a part belonging to a reinforced concrete foundation.
  • the prefabricated construction element 1 comprising concrete can for example be any one of a prefabricated reinforced concrete column/pile/pillar, as illustrated in figures 1 to 3 , a prefabricated reinforced concrete beam, as illustrated in figure 7 , and a prefabricated concrete wall element, as illustrated in figures 4 to 6 .
  • Said another construction element 2 can also be a prefabricated construction element 1 comprising concrete for example a prefabricated reinforced concrete column/pile/pillar, as illustrated in figure 7 .
  • said another construction element 2 can be a cast-in-situ construction element comprising concrete such as a reinforced concrete foundation or a part belonging to a reinforced concrete foundation, as illustrated in figures 1 to 6 .
  • the method comprises a connecting step for connecting the prefabricated construction element 1 by means of repeatably openable and closable mechanical connection means 3 to said another construction element 2 so that a joint 4 is formed between the prefabricated construction element 1 and said another construction element 2 and so that the joint 4 is at least partly limited by the prefabricated construction element 1 and said another construction element 2.
  • the method comprises a grouting step for grouting the joint 4 by covering such as filling the joint 4 at least partly with grout 5 and allowing the grout 5 to harden.
  • the method comprises a coating step for coating surfaces 6 of the prefabricated construction element 1 that is to be covered by grout 5 in said grouting step at least partly with separation means 7 such as with anti-adhesion means prior said grouting step.
  • mechanical anti-adhesion means such as perforated or unperforated plates, sheets or films be used as separation means 7.
  • mechanical anti-adhesion means can for example be used an expanded steel sheet, a perforated steel sheet, a plate of polymer, a sheet of polymer, a film of polymer, a textile sheet, a fabric sheet, formwork liner, and wood such as coated plywood.
  • An advantage that is achieved by using a perforated plate, sheet or a film as a separation means 7 is that the perforations allows for grout 5 to attach to the prefabricated construction element 1 through the separation means 7. This provides for a stronger connection between the grout 5 and the prefabricated construction element 1 while allowing for easy detaching of the prefabricated construction element 1 from the separation means 7 and from the grout 5.
  • anti-adhesion substances such as fluid for example oil, cementitious retarder, or carbon be used as separation means 7.
  • the coating step includes preferably, but not necessarily, providing for the coating step a separation means 7 that is a means separate from the prefabricated construction element 1, i.e. that does not form a part of the prefabricated construction element 1, and that is a means separate from said another construction element 2, i.e. that does not form a part of said another construction element 2.
  • the separation means 7 is preferably, but not necessarily, arranged to at least partly follow an interface (not marked with a reference numeral) i.e. a connection surface between the grout 5 that is configured to cover the prefabricated construction element 1 in the joint 4 and the surfaces 6 of the prefabricated construction element 1.
  • the method allows easy removal of the prefabricated construction element 1 from grouting without damaging the prefabricated construction element 1, because the grout 5 will not adhere to the surfaces 6 of the prefabricated construction element 1 because of the separation means 7.
  • the coating step includes preferably, but not necessarily, additionally coating surfaces 6 of said another construction element 2 that is to be covered by grout 5 at least partly with separation means 7 such as with any alternative of the separation means 7 presented prior said grouting.
  • the separation means 7 is preferably, but not necessarily, arranged to at least partly follow an interface (not marked with a reference numeral) i.e. a connection surface between the grout 5 that is configured to cover said another construction element 2 in the joint 4 and the surfaces 6 of said another construction element 2.
  • the method allows easy removal of the from the said another construction element 2 without damaging said another construction element 2, because the grout 5 will not adhere to the surfaces 6 of said another construction element 2 coated by separation means 7.
  • the connecting step includes, as illustrated in figures 1 to 7 , providing repeatably openable and closable mechanical connection means 3 comprising anchor bolts 8 extending from said another construction element 2.
  • the connection step includes screwing first nuts 9 on the anchor bolts 8 so that the nuts are at a distance from said another construction element 2, as illustrated in figures 1 to 3 .
  • the connection step includes arranging the anchor bolts 8 to penetrate openings 10 in the prefabricated construction element 1 so that the first nuts 9 are between said another construction element 2 and the prefabricated construction element 1 and a grouting space 11 is formed between said another construction element 2 and the prefabricated construction element 1.
  • the connection step includes screwing second nuts 12 to the anchor bolts 8 to secure the prefabricated construction element 1 to the anchor bolts 8.
  • a washer 17 is arranged at the anchor bolts 8 between the openings 10 and second nuts 12.
  • the method includes preferably, but not necessarily, arranging in the connection step the anchor bolts 8 to penetrate openings 10 formed in metal plates 13 of connector elements 14 at least partly cast into the concrete of the prefabricated construction element 1.
  • connector element 14 can for example be in the form of a column shoe, as illustrated in the embodiments shown in figures 1 to 3 , a beam shoe, as illustrated in the embodiment illustrated in figure 7 , or a wall shoe, as illustrated in the embodiments shown in figures 4 and 5 , depending on the form of the prefabricated construction element 1.
  • connection step includes arranging the anchor bolts 8 to penetrate openings 10 in the prefabricated construction element 1 so that the anchor bolts 8 extend into a cavity 15 in the prefabricated construction element 1, and the connection step includes screwing said second nuts 12 to the anchor bolts 8 inside the cavities so that the second nuts 12 will be housed in the cavities.
  • the method includes a filling step for filling the cavities at least partly with other material 16 than grout 5 prior said grouting step to at least partly prevent grout 5 from entering said cavities.
  • At least one of mineral wool, gypsum, plaster and lime mortar is used as said other material 16 in the filling step. These materials are easier to remove than concrete or mortar so that the repeatably openable and closable mechanical connection means 3 can be accessed in the cavity 15 and be opened, as exemplified in figure 8 .
  • the method can include providing the prefabricated construction element 1 with at least one of a projection formation 20 configured to project into grout 5 in the joint between the prefabricated construction element 1 and said another construction element 2 and a cavity formation 21 into which grout 5 from the joint between the prefabricated construction element 1 and said another construction element 2 is configured to project.

  • the construction element 1 can be provided with a formation 20 that extend into a cavity 21 in the grout 5 between the prefabricated construction element 1 and said another construction element 2, as illustrated in figure 2 .
  • construction element 1 can alternatively be provided with a formation 20 that extend into a cavity 21 in said another construction element 2, as illustrated in figure 3 .
  • shear force transfer capacity between the prefabricated construction element 1 and said another construction element 2 be increased, while still creating an easily dismountable connection allowing reuse of a least the construction element 1, by forming a cavity 21 in the surface 6 of the prefabricated construction element 1 so that the cavity 21 is configured to be filled with the grout 5 cast between the prefabricated construction element 1 and said another construction element 2, as illustrated in figure 5 .
  • shear force transfer capacity between the prefabricated construction element 1 and said another construction element 2 be increased, while still creating an easily dismountable connection allowing reuse of a least the construction element 1, by forming a cavity 21 both in the surface 6 of the prefabricated construction element 1 and in the surface 6 of said another construction element so that both cavities 21 are configured to be filled with the grout 5 cast between the prefabricated construction element 1 and said another construction element 2, as illustrated in figure 6 .
  • the anchor bolts 8 are preferably, but not necessarily, threaded bars, which are screwed into threaded muffs 17, which are casted into concrete of said another construction element 2 so that the threaded muffs 17 extend from the surface 6 of said another construction element 2 into said another construction element 2, and which are anchored by means of anchoring means 18 fastened to said threaded muffs 17 and also casted into concrete of said another construction element 2.

  • separation means 7 such as anti-adhesion means 7 is present between surfaces 6 of the prefabricated construction element 1 that is at least partly covered by grout 5 and said grout 5 at least partly covering the joint 4 and that allowed to harden.
