Definitions

  • the invention relates to a hollow glass brick with the features of the preamble of claim 1 and a wall element comprising at least two such hollow glass bricks, which are suitable for single-shell fire-resistant wall parts of fire resistance class F 30.
  • Wall parts of fire resistance class F 30 must remain effective in the fire tests specified in DIN 4102 for a period of at least 30 minutes as a room closure. During this time, on the side facing away from the fire, they may on average not warm up by more than 140 K above the initial temperature, and at no measuring point may a temperature increase of more than 180 K above the initial temperature occur.
  • Wall parts with commercially available hollow glass bricks only meet these requirements if the wall surfaces consisting of the hollow glass bricks are double-skinned, i.e.
  • a second wall surface is arranged parallel to the glass brick wall surface, which is also formed from glass bricks or from glass panes with corresponding fire-resistant properties.
  • a relevant hollow glass brick is known, between the half-shells of which a wire glass pane is inserted so densely by means of a suitable cement that a partial vacuum can be obtained in the two partial spaces on both sides of the glass pane.
  • This hollow glass brick is also provided as a fire protection element, the wire glass pane being used to prevent the breakthrough of flames.
  • the cited document says nothing about the wall thicknesses of the visible surface walls to be provided.
  • DE-A-28 30 504 describes a further hollow glass brick with a glass pane inserted between its half-shells, which is provided with an IR-reflecting coating.
  • This equipment of the hollow glass brick not intended for fire protection is intended to reduce the thermal permeability of a wall made with it.
  • the invention has for its object to provide a hollow glass brick with which single-walled wall parts can be produced, which correspond to fire resistance class F 30, and to create such a wall element comprising hollow glass bricks. According to the invention, this object is achieved by a hollow glass block with the features of claim 1 and by a wall element with the features of claim 6.
  • the dependent claims subordinate to these claims indicate advantageous developments of these objects.
  • the hollow glass brick according to the invention is characterized in that its two walls forming the visible surfaces have a wall thickness of at least 18 mm and at most 25 mm.
  • the wall element is provided with a circumferential reinforced edge strip of at least 55 to 60 mm in width and 80 mm in thickness made of a heat-insulating mortar or a corresponding concrete.
  • the reinforced joints of approx. 15 mm width between the hollow glass blocks are also filled with thermal insulation mortar or concrete.
  • the wall thickness of the visible surfaces of the glass stone half-shells can be up to about 25 mm; it is preferably approximately 19 to 22 mm. With this preferred wall thickness the requirements of fire resistance class F 30 fully satisfied, and secondly, Glass stone half-shells with these wall thicknesses with the usual existing presses still without create manufacturing difficulties.
  • Another improvement in fire resistance properties can be achieved if in further development of the invention the one arranged between the glass stone half-shells Glass pane on at least one side with one IR-reflective coating is provided.
  • the two glass stone half shells can be used together be welded, the glass pane in this case the welding process in one of the two glass stone half-shells is inserted near the subsequent weld seam.
  • the hollow glass brick consists of the two Glass stone half-shells 1, 2 and in the middle plane of the Hollow glass stone arranged glass pane 8.
  • the two Glass stone half-shells 1, 2 are preferably identical formed and have a wall 3 forming the visible surface and a peripheral side wall 4.
  • the the visible area forming wall 3 has a thickness of about 20 mm, and the circumferential side wall 4 the usual thickness of about 5 to 10 mm.
  • the wall 3 forming the visible surface is along their circumference with a peripheral edge bead 5. However, it is also possible to use the visible surfaces Edge bead 5 omit and in this way the Form visible surfaces of the wall 3 to the edge.
  • the glass pane 8 consists of 4 mm thick float glass. By this glass sheet 8 is the required insulation against reaches heat in the event of fire. If the Glass pane 8 on one or on both sides with one IR-reflecting layer 9 is provided as a result the heat insulation effect further increases because of this Way the radiation portion of the heat transfer through the Glass pane is further reduced.
  • the IR reflective Layer 9 can be pyrolytically applied Be metal oxide layer, for example a layer of fluorine-doped tin oxide, or one after a Multi-layer vacuum applied with one Functional layer made of silver, but can be of course all other known ones Use IR reflecting layers for this.
  • connection of the glass stone half-shells 1, 2 and Glass pane 8 takes place with one another via adhesive layers 10 from a water vapor diffusion-tight adhesive.
  • suitable Glue that has the required properties in terms durability and water vapor tightness have are commercially available. Has proven itself for example the one under the trade name PACTAN 3040 known adhesives from the "Heidelberger Building Material Technology ".
  • the enclosed in the hollow glass brick Air must be permanently dry to a low level Ensure dew point. Gluing the Glass stone half-shells with the glass pane are therefore made in dry air.
  • Prefabricated wall elements can also be made from these hollow glass bricks. These are expediently provided with a circumferential reinforced edge strip of at least 55 to 60 mm in width and 80 mm in thickness made of a heat-insulating mortar or a corresponding concrete.
  • reinforced joints approx. 15 mm wide must also be made of thermal insulation mortar or concrete.
  • the joints must be grooved horizontally in each joint with 2 x ⁇ 6 mm hot-dip galvanized rebar S 500, and vertically in every second joint with 1 x ⁇ 6 mm hot-dip galvanized rebar S 500.
  • Such a wall element which receives no additional vertical load apart from its own weight, can have a size of up to 9.0 m 2 , the height of the wall element being limited to a maximum of about 3.5 m 2 .
