Definitions

  • the invention relates to a frameless glass balustrade in particular in combination with at least one concrete floor element. More in particular the invention relates to a combination of a prefabricated cast concrete floor element and at least one frameless glass panel forming a balustrade. The invention also relates to a method of forming an integral groove in cast concrete floor elements for receiving an edge of a glass panel therein.
  • a plate shaped balustrade attached to an edge of a floor in a building construction is know from Dutch patent document NL 1035234 .
  • This known balustrade uses a mounting profile that has a flange attached to the floor edge, and a U-shaped accommodation space for receiving the plate shaped balustrade element.
  • the balustrade element can be a glass panel, but as shown in this known arrangement it is provided with an upper railing. To obtain full benefit of an unobstructed view through glass panels, such panels are preferably used without frames, which presents a challenge to their mounting especially when structural security is needed, such as with balcony balustrades.
  • the use of mounting profiles and railings in the known balustrade may obstruct free view, or may esthetically be objectionable.
  • US2015110552A1 shows a glass balustrade showing the features of the preamble of claim 1.
  • an object of the present invention to propose an improved frameless glass balustrade in combination with a concrete floor element, and method of obtaining same.
  • the invention provides for a frameless glass balustrade and method of obtaining same as defined in one or more of the appended claims.
  • the elastic spacer means in particular can contain at least one of rubber, sealant and caulking.
  • the glass panel is separated from a bottom of the recessed groove by at least one pre-formed rubber element, it becomes very convenient to position the glass panel without any risk of damage.
  • a drain hole is provided that extends between a bottom of the groove and a lower surface of the floor element opposite the upper surface. This is particularly advantageous when the prefabricated concrete floor element is installed at a building site, while the glass panels are to be installed at a later stage. In such a situation any water spillage or rain collecting in the recessed groove can drain off through the drain hole, before it would interfere with the mounting of the glass panel. Notably the structural integrity of sealant or caulking could be seriously compromised, when any water would be present in the groove.
  • core elements with complementary ends that can be coupled with one another to obtain different lengths and arrangements.
  • Further core elements can be provided for forming drain holes, and advantageously these can also be connected with the groove forming core elements.
  • Figure 1 schematically depicts a cross-section of an embodiment of the prefabricated concrete floor element 1.
  • the element 1 is provided with a recessed groove 3 formed in an upper surface 4 of the concrete floor element 1.
  • An elevation 5 along the substantially horizontal upper surface 4 of the floor element 1 surrounds the recessed groove 3 and a drain hole 7 which extends between a bottom of the recessed groove 3 and a lower surface 2 of the floor element opposite to the upper surface 4.
  • FIG. 2 A schematic cross section of an embodiment of the concrete floor element during the moulding thereof can be seen in Fig. 2 .
  • a mould 11 is provided that has an internal size and form substantially corresponding to a size and form of the floor element 1.
  • the mould 11 comprises at least one elongated first core element 13 having a cross-section that substantially corresponds to that of the recessed groove 3.
  • the first core element 13 can be of a relatively inflexible material, but preferably is of a material that has at least some flexible quality.
  • the first core element 13 can be based on polystyrene, polyurethane foam, expanded thermoset polymers, other synthetic foam materials, elastomer, rubber, or like material.
  • the flexible first core element 13 can be bended to allow for a curvature of a recessed groove to be formed thereby.
  • the first core element 13 is shown to be held in position by an upwardly extending protrusion 15 from an internal bottom surface 14 of the mould 11.
  • the mould 11 is shown to contain an appropriate amount of fluid concrete 17 to form the floor element 1.
  • a second core element 19 possesses a substantially cylindrical form, is provided to extend longitudinally upwards from the surface of the first core element 13 to above the upper surface level 20 of the fluid concrete 17.
  • the second core element 19 can be of a plastic such as a polyvinylchloride, polyethylene, polyurethane or a steel, stainless steel, aluminum or other sturdy materials, and can have a tubular form.
  • the mould 11 further comprises a recess 21 parallel to and along the elongated first core element 13 to form the elevation 5 in the concrete floor element 1 and is shaped in negative of an upper surface 4 of the floor element 1.
  • the mould 11 is further provided with negative surface elements 23, 25.
  • the cross-sectional view of Fig. 3 is parallel to the longitudinal direction of the first core elements 13.
  • the first core elements 13 are depicted in Fig. 3 to be held in place by the upwardly extending protrusion 15 which extends over substantially the length of the first core element 13 in the form of a ridge, this protrusion 15 can also be formed by a series of separate upward protrusions either spaced at intervals, which are preferably regular, by which the core element 13 is held in position.
  • the second core element 19 is provided to extend from the surface of the first core element 13 to above the upper surface level 20 of the fluid concrete 17.
  • FIG. 4 shows a cross-section of an embodiment of the present invention.
  • a prefabricated cast concrete floor element 1 is provided with a frameless glass panel 27 positioned with a lower edge in the recessed groove 3 formed in the upper surface 4 of the concrete floor element 1.
  • the glass panel 27 is separated from concrete walls of the recessed groove 3 by means of vertical spacers 29.
  • the concrete floor element 1 contains the elevation 5 along its substantially horizontal upper surface 4 to surround the recessed groove 3.
