Definitions

  • the present invention relates to the construction industry. More specifically, the present invention is used in concrete construction where a balcony slab is attached to a main floor slab. When a balcony slab is attached to a main floor slab, a thermal bridge is created between the outside balcony slab and the inside floor slab. To avoid this problem, a thermal block is inserted between the slabs.
  • the present invention is a compression transfer member which may be used in the thermal block for structural stability.
  • Balconies are a common feature in buildings, particularly residential buildings. For example, apartments and hotels often include balconies.
  • the interior floor slab is extended to the outside to create the balcony.
  • the concrete and internal reinforcing, such as rebar, are extended from the interior slab to create a balcony slab.
  • the balcony slabs must be extended without any thermal break between the balcony slab and the interior floor slab, which is undesirable from an energy perspective.
  • products have been introduced to provide a thermal break between balcony and floor slabs which meet the structural requirements necessary for balcony construction.
  • United States Patent No. 5,822,938 to Bahr et al. discloses a structural element for thermal insulation. Specifically, disclosed is a complex system of insulation and compression elements which are located between main and projecting building parts. The compression elements end at contact plates or bars, which are located adjacent to the building elements. The plates or bars may include one or more projections which extend into the concrete slabs.
  • the system of Bähr et al. has drawbacks. It is a complex system which must be arranged in a specific manner in the building to effectively transfer compression forces. Moreover, the Bahr et al. compression elements must extend the entire compression height of the junction between the building and projecting parts. Furthermore, because the
  • compression members do not extend into the concrete elements, the compression members are likely to be displaced as the concrete expands and contracts.
  • the Bahr et al. device is made of steel, which can be corrosive and also creates greater thermal bridge and, therefore, is undesirable.
  • United States Patent No. 8,973,317 to Larkin discloses a thermal break for concrete slab edges and balconies.
  • the thermal break includes a plate made of insulation that includes apertures.
  • the apertures accept nipples which are used to extend the rebar of the main building to a projecting balcony slab for the transfer of compression and tension forces.
  • the rebar which extends to the balcony slab is connected to the internal reinforcing or rebar network in both the main floor and balcony slabs, creating a complex system to be constructed.
  • the current invention provides a compression member that will replace the steel compression members that are currently employed.
  • the present invention accommodates the expansion and contraction of the concrete slabs while providing sufficient compression strength and anchorage in the concrete. Moreover, the invention is easy to manufacture, assemble, and install.
  • a compression member for concrete may include an elongated body extending into first and second independent concrete structural elements.
  • the elongated body may have a cross-section including at least two independent rounded surfaces.
  • the first and second independent concrete structural elements may extend in horizontal planes when the concrete structural elements are in their service positions.

  • horizontal planes includes planes which are truly horizontal and those which are nearly or intended to be horizontal, such as, sloped surface to drain water, construction inaccuracies, expansion, contraction, or slight design variations.
  • the compression member 100 of the present invention is useful for transferring compression forces and loads between a balcony and a main floor slab of a building. It should be appreciated that the compression members 100 may also be used in other horizontal applications known now or in the future.

  • insulation 122 Further included in the connector assembly 114 is insulation 122, which may be the same or a different insulation material as in the wall 106 or same or different thickness insulation material as in wall 106.

  • the maximum stress occurs at the junction of the balcony slab to the interior floor slab.
  • the top of the slab is in tension, while the bottom of the slab is in compression. Because the concrete is removed at this location, the compression resistance for the loads is removed.

Abstract

L'invention porte sur un élément de compression pour un ensemble de raccord thermiquement rompu, par exemple pour un balcon. Dans un mode de réalisation, l'élément de compression comprend un corps allongé qui s'étend dans des premier et second éléments structurels en béton indépendants. Le corps allongé comprend une section transversale. La section transversale peut comprendre au moins deux surfaces arrondies indépendantes. La section transversale peut comprendre au moins un coin, qui peut être arrondi. La section transversale peut de plus comprendre au moins une patte. Les premier et second éléments structurels en béton indépendants peuvent s'étendre dans des plans horizontaux quand les éléments structurels en béton indépendants sont dans leur position de service. L'élément de compression transfère des forces de compression entre les premier et second éléments structurels en béton indépendants. De plus, l'élément de compression peut être indépendant du renfort interne, ou barre d'armature, de l'un ou des deux éléments structurels en béton indépendants.
