Definitions

  • the invention relates to a method for extending the habitable space of a building.
  • An object of the invention is to obviate or reduce these problems and to provide an efficient and effective method for extending the habitable space of a building.
  • the coupling elements which can be coupled to the bearing elements for instance comprise bolts and/or nuts.
  • the structural unit is for instance a room, a conservatory or a bridge walkway, such as an external walkway between two parts of a building.
  • a unit can for instance have a length of up to about 3 metres, i.e. after placing of the unit the front side of the building extends up to about 3 metres further than it did previously.
  • the structural unit is for instance a room with two substantially vertical walls and two substantially horizontal walls.
  • the vertical walls form the side walls of the room and the horizontal walls form the floor and the ceiling of the room.
  • the horizontal and vertical walls can form a continuous edge, the modular dimensions of which correspond to the dimensions of the building, i.e. the pitch distances between adjacent horizontal and vertical walls.
  • the structural unit is a room with one horizontal wall, which for instance forms the floor. Such units can be placed on a building one above another so that the floor of the one unit forms the ceiling of the other.
  • the side of the prefabricated modular structural unit facing toward the building is preferably open. After installation of the unit an existing living area hereby continues into the added space of the extension unit.
  • the two substantially vertical walls of the structural unit are situated at a distance from each other corresponding to a whole multiple, including one, of a horizontal pitch distance between vertical walls of the building.
  • This is for instance a pitch distance between adjacent vertical walls, so that after application of the method according to the invention the unit forms an extension of the space lying therebetween.
  • the unit comprises substantially vertical walls situated at respectively two or more times the pitch distance from each other.
  • a prefabricated modular structural unit is for instance provided having two substantially horizontal walls which are situated at a distance from each other corresponding to a whole multiple, including one, of a vertical pitch distance between horizontal walls of the building. It is hereby possible in one operation to provide spaces on adjacent floors of the building with an extension in the form of the structural unit.

It is possible to provide the whole wall of a building with extension units or to extend a part of the building in this manner. It is further possible to place one or more structural units on multiple sides of a building.
  • the prefabricated modular structural unit is preferably provided with insulation. This has the additional advantage that, in addition to extending the habitable space, a better insulated space is also created.
  • the insulated structural unit can enclose possible cold bridges in the building, thereby improving the insulation of the dwelling as a whole. This is particularly advantageous in the renovation of existing buildings, since these are often poorly insulated.
  • step c) of the above stated method comprises the following steps of:
  • the part of the bearing element which is placed in the recess preferably comprises a tensively strong anchoring protrusion.
  • the curing mass is for instance mortar, concrete or glue.
  • step c) of the method further comprises of biasing an element which can be under strain of tension.

  • the bearing beam will mainly absorb the vertical forces that are exerted.
  • the bearing beam is preferably a steel I-profile.
  • the wall mounting comprises a rotation-blocking mounting.
  • the rotation-blocking mounting can for instance comprise an anchor.
  • the rotation-blocking mounting blocks rotation of the bearing body, for instance rotation along the wall or away from the wall. A strong mounting of the bearing element is hereby realized.
  • Such a mounting moreover achieves that the bearing element can be adjusted, positioned and temporarily fixed for the purpose of pouring a curing mass such as mortar.
  • the wall mounting preferably comprises at least one tensively strong anchoring protrusion, a bearing beam and a rotation-blocking mounting.
  • the tensively strong anchoring protrusion absorbs mainly the exerted moment of force
  • the bearing beam absorbs mainly the vertical forces
  • the rotation-blocking mounting prevents a rotation of the bearing element.
  • anchoring protrusion, the bearing beam and the rotation-blocking mounting are positioned such that in use the anchoring protrusion is situated higher relative to the gravitational force than the bearing beam, which is situated higher than the rotation-blocking mounting.
