Definitions

  • the supporting bracket for facade structures and the system for fixing of façade structures are applicable in the field of construction, during the building of ventilated façades.
  • the main bearing and fixing element of the façade is a bracket.
  • the bracket is fixed directly to the building structure. Because of this fact, the bracket acts as a thermal bridge between the outer cladding and the inner space of the building, especially in the case of buildings with a metal structure.
  • the main disadvantage of the known solutions is that they do not ensure compliance with fire safety requirements, i.e. the plastic element or construction melts at high temperatures and the façade falls off.
  • bracket The use of aluminum or stainless steel as a material for the bracket is due to a corrosion and fire resistance requirement.
  • the two materials have their respective technological advantages and disadvantages.
  • Aluminum is light, easy to reprocess and mechanically modify on the façade itself when needed. For example, when it is necessary to cut protruding elements or drill additional holes during leveling of the façade structure due to the curvature of the wall.
  • Aluminum is eco-friendly, i.e. it is possible to completely reprocess it.
  • a disadvantage of aluminum is that its thermal resistance is 15 times lower than that of stainless steel.
  • the task of the invention is to create a bracket for façade structures with decreased thermal conductivity and a high level of safety, which ensures strength of the façade structure to which it is fixed, and which can easily be modified and reprocessed when needed.
  • This task is performed by creating a supporting bracket for façade structure that includes a metal-made base for fixing of the supporting bracket to a building structure, at least one intermediate detail and at least one end detail for fixing to a supporting profile of a façade substructure, wherein at least one intermediate detail and one end detail are made of metals with different thermal conductivity so as to decrease the thermal conductivity between them.
  • the at least one end detail prefferably be made of aluminum or aluminum alloy, so that it can be easily treated even during fixing of the bracket.
  • the at least one intermediate detail prefferably be made of steel for preservation of high thermal resistance and, accordingly, increased safety in case of a fire.
  • the at least one intermediate detail and the base are made as a steel monolithic detail.
  • the shape of the base with the at least one intermediate detail is selected from the following embodiments:
  • the base and the at least one end detail are made of aluminum or aluminum alloy, wherein the at least one intermediate detail is made of steel.
  • the shape of the base is selected from the following embodiments:
  • the at least one intermediate detail has an open-end hole.
  • each set of fixing elements includes a plastic insulation detail with a hole for a fixing element and that plastic insulation detail is positioned between the metal details of the supporting bracket, thus creating distance between them.
  • the plastic insulation detail completely covers the area where the respective metal details of the supporting bracket overlap.
  • An additional task of the invention is the creation of a fixing system for façade structures, where the thermal conductivity between the load-bearing profile subconstruction and the building structure is to be decreased.
  • This task is performed through the creation of the system for fixing of facade structures that includes a supporting bracket for facade structures, according to the invention, installed in one end to a building structure and in a second end to a load-bearing profile subconstruction.
  • the base of the supporting bracket is fastened by fastening elements to a building structure and the at least one end detail of the supporting bracket is fastened by fastening elements to a supporting profile of the load-bearing profile subconstruction.
  • the described supporting bracket for façade structures and system for fixing of façade structures ensure higher thermal resistance compared to the solutions known from the state of the art, because the steel details ensure a partial thermal barrier for the thermal conductivity from the aluminum details in the construction of the bracket. Simultaneously, the bracket remains fire-resistant, the probability of it falling off is decreased, an opportunity is secured for easy correction and modification of the aluminum details on site at the façade itself as well as an opportunity for easy and cheap subsequent reprocessing.
  • the supporting bracket for façade structures includes a metal-made base 1 for fixing of the supporting bracket to a building structure 9, an intermediate detail 2 and an end detail 3 for fixing to a supporting profile 8 of a façade substructure.
  • the intermediate detail 2 and the end detail 3 are connected to each other through familiar fixing elements 5.
  • the intermediate detail 2 and the end detail 3 are made of metals with different thermal conductivity - steel and aluminum.
  • the thermal bridge, created between them, is reduced; accordingly, the degree of thermal insulation is increased.
  • aluminum alloy instead of aluminum.
  • the embodiments for use of these metals are:
  • the advantage of the end detail 3, made of aluminum or aluminum alloy is that it can easily be modified in the place of installation; for example, it can be shortened, if necessary, by cutting the unnecessary part of the end detail 3.
  • the used steel prefferably be stainless or galvanized, but it is possible to use other types of steel, known from the state of the art.
  • the intermediate detail 2 and the base 1 are made as separate details, connected with fixing elements 5 ( fig. 1 , 2 , 3, 4 , 7 and 8 ) as well as being a single, monolithic detail ( fig. 5 and 6 ).
  • fixing elements 5 fig. 1 , 2 , 3, 4 , 7 and 8
  • they're a monolithic detail they are made of steel.
  • the details can be connected by more than one fixing element 5; for example, with two fixing elements 5, as shown in figures 3 to 8 .
  • more than one fixing element 5 for example, with two fixing elements 5, as shown in figures 3 to 8 .
  • the shape they form can be selected from the following embodiments:
  • the base 1 prefferably be made of one straight detail
  • the intermediate detail 2 prefferably be with a U-shape, L-shape or T-shape and to be fastened to the base 1 so that it has a disengaged arm/s for connection with an end detail 3.
  • the base 1 it is possible for just the base 1 to have a U-shape ( fig. 1 , 2 , 3 and 4 ), or an L-shape ( fig. 5 ), or a T-shape ( fig. 8 ), wherein a straight intermediate detail 2 is each to be fastened to the one disengaged arm of an L-shaped or T-shaped base 1, or to each of the two disengaged arms of a U-shaped base 1.
  • the base 1 it is possible for the base 1 to have a formed slot 6 to each arm, to which an intermediate detail 2 is fixed and in that slot, the end of the intermediate detail is inserted, made as a plate, as shown in figures 1 , 2 , 3, 4 , 7 and 8 .
  • the slot 6 can be formed on one side of the arm as a slit in the part of the base 1, which is fixed to the building structure 9 or through an additional rib ( fig. 1 , 2 , 3, 4 ) to protrude from the base 1 in proximity to its respective arm.
  • each arm of the base 1 that connects with an intermediate detail 2 to be made as two parallel parts ( fig. 7 and 8 ), thus forming a slot, into which the intermediate detail 2 is inserted.
  • the slot 6 serves as additional fixing of the intermediate detail 2 to the base 1, but it is not mandatory, because the use of fixing elements 5 for their connection ensures the fixing.
  • the slot 7 serves for stronger fixing of the details.
  • This slot 7 is formed through a protruding L-shaped rib from the end detail 3, in which the end of the intermediate detail 2 is placed.
  • the end detail 3 it is possible for the end detail 3 to have a transverse restraining rib, onto which the intermediate detail 2 rests directly or indirectly. It is also possible for the end detail 3 to not have a rib and a slot, and to be fastened to the intermediate detail 2 only by fastening elements 5.
  • the base 1 and/or the at least one intermediate detail 2 and/or the at least one end detail 3 are plates, as shown in the figures.
  • All of the details of the supporting bracket can be made with different thicknesses, as long as they retain their functionality and strength.

  • the used fixing elements 5 can be different fixing elements, known from the state of the art, like, for example, a bolt and nut, a rivet, a screw or another type of fixing element.
  • the intermediate detail 2 can have an open-end hole 10 as shown in figures 6, 5, 7 and 8 .
  • the size of the hole 10 corresponds inversely to the created thermal bridge, therefore, the bigger the hole 10, the smaller the thermal bridge.
  • the aim is to make the intermediate detail 2 with an optimized hole 10, having the created thermal bridge be minimal between the base 1 and the end detail 3 while having the intermediate detail 2 strong enough to support the respective building structure.
  • each set of fixing elements 5 can include a plastic insulation detail 4 with a hole for a fixing element 5, that insulation detail 4 being located between the metal details of the supporting bracket, thus creating distance between them.
