Definitions

  • the present invention relates to a beam and block floor.
  • the invention further relates to a method of producing such a floor and to a beam for use in such a floor.
  • Beam and block floors are typically formed by an array of equidistantly arranged horizontal beams provided with substantially horizontal support surfaces, a plurality of blocks between the beams resting on the support surfaces and concrete covering the beams and the blocks.
  • the blocks are generally made of a thermo-isolating material, such as Expanded Polystyrene (EPS), or any other suitable material, such as ceramic, clay or concrete. These blocks serve as a mould for the concrete.
  • the blocks can for example be mainly rectangular blocks, with or without chamfered sections, or they can be plates or shells, e.g. curved shells, or they can have any other suitable shape.
  • a metallic reinforcement mesh can be arranged on top of the beams. Concrete is poured over the beams and blocks. After hardening the different components of the floor cooperate as a coherent composed structure. Such floors show good structural and isolating performance, can be constructed relatively quick and involve low expenses. Such floors are typically used in residential buildings.
  • the beams used in such Floors are usually beams of pretensioned or reinforced concrete, which have inverted T-shape cross sections.
  • Such concrete beams are heavy and difficult to handle.
  • such concrete beams are relatively fragile, so during assembly of the floor such concrete beams may need additional temporary supports to avoid downward bending of the floor caused by its own weight, which would substantially deteriorate the structural performance of the resulting floor.
  • NL 1012339 discloses a block and beam floor using light weight beams of a fibre reinforced polymeric material. It has been found that such beams have limited load capacity and need additional support during building of the floor.
  • WO 2009/109893 discloses a floor using beams made of two sheet metal parts with L-shaped cross section, e.g. of galvanised steel, arranged back to back to form an inverted T-shape.
  • the two parts can be connected, e.g., by welding.
  • Such beams have a relatively low load capacity and need additional temporary supports during assembly of the floor. Moreover, the welding connections and the ends of such beams are easily exposed to corrosion.
  • the object of the invention is achieved with a floor comprising blocks, beams provided with support surfaces for supporting the blocks and a layer of concrete structurally connecting the beams and covering the blocks, wherein at least a part of the beams are formed from a metal sheet folded to form a beam with the desired cross section, wherein the cross sectional ends of the metal sheet are embedded in the concrete.
  • connection means are for instance a weld, spot welds, dowels, rivets and/or clinch connections, e.g., clinch connections of the type provided by the German company Tox Pressotechnik.
  • the sheet ends overlap each other.
  • the outer ends of the beams are embedded in the concrete. These outer ends form typical spots for corrosion. By embedding these spots in the concrete layer these outer beam ends can effectively be protected against corrosion.
  • the metal sheet can for instance be a steel sheet.
  • the steel is galvanized or provided in any other suitable way with a protective layer, such as a zinc layer.
  • the steel can for instance be cold rolled galvanized steel.
  • the beam parts which are embedded in the concrete layer can be provided with local deformations, such as impressions.
  • the beams can be dimensioned in such a way that in use the top sides of the beams protrude above the blocks.
  • This way one or more reinforcement meshes can be placed on the top sides of the beams, at a distance above the blocks. Such meshes may considerably enhance the load capacity of the floor as a constructional unit.
  • the beams will generally have a symmetrical cross-section, although non-symmetrical configurations can also be used, if so desired.
  • the beams can for example enclose one our more hollow spaces extending in longitudinal direction of the beam.
  • a wall of at least one of the hollow spaces may border the lower side of the beam.
  • the lower side can be used for providing fastening means, e.g., to attach further constructional elements, such as piping, ceiling elements, etc..
  • the beam comprises two such hollow spaces, e.g., an upper hollow space and a lower hollow space.
  • the hollow spaces can be triangular in cross section.
  • the triangular spaces can be configured to point towards each other.
  • a web may bridge the two triangular hollow spaces.
  • the overlapping cross sectional ends of the metal sheet are preferably located at a section of the web which is embedded in the concrete layer.
  • the support surfaces of the beam for carrying the blocks may extend from both lateral sides of the lower surface of the lower hollow space.
  • the triangular hollow space may for instance be smaller than the upper hollow space.
  • Such a beam can be folded from a metal sheet in such a way that the web and the support surfaces are double walled while the walls of the hollow spaces are single walled.
  • the beams can for instance have a weight of 7,5 kg/m or less, e.g., 7 kg/m or less or even 6,5 or less and still have a load capacity which is sufficient to avoid the need for auxiliary supports during construction of the floor, even when people need to walk over the blocks resting on the support surfaces of the beams before the concrete is poured.
  • the weight of the beams can be kept well below weights (presently 28 kg) for which present-day legislation in most European jurisdictions would prescribe the use of auxiliary lifting means.
  • the blocks will generally be thermal isolation blocks, e.g. of expanded polystyrene, although other block types can also be used if so desired, such as ceramic materials, clay, plastic or concrete or any other suitable formwork material.
  • the blocks are typically provided with shoulders resting on the support surfaces provided by the beams.
  • the blocks can be provided with a lateral edge gripping around the lower surface of the beam and abutting the lower part of the side edge of an adjacent block. This way, an isolation layer can be obtained which is not interrupted by the beams and the formation of bridges can effectively be prevented.
  • the beam material is better isolated from cold coming from below, so condensation on the beam surfaces is substantially reduced.
  • Figure 1 shows in cross section a floor 1 made of blocks 2, equidistantly arranged horizontal beams 3 and a layer of concrete 4 which covers the blocks 2 and beams 3. At both lateral sides the beams 3 are provided with support surfaces 5 for supporting the blocks 2.
  • the hardened concrete layer 4 structurally connects the beams 3 and cooperates with the beams 3 to function as a single structural unit.
  • the ends of the beams 3 are supported by parts of the buildings construction or foundation (not shown).
  • the beams 3 are formed from a steel sheet material 31 folded to form a beam with the desired cross section.
  • the steel sheet 31 is galvanized to form a protective zinc layer.
  • the ends 32, 33 of the sheet metal 31 overlap and are connected, e.g., by welding, spot welding, rivet, dowel or clinch connections.
  • the connected ends 32, 33 of the metal sheet 31 are fully embedded within the concrete layer 4. This way, the connected ends 32, 33 are effectively protected against corrosion.
  • the outer beam ends (not shown) of the beams 3 are fully embedded in the concrete layer 4. These ends are typically not or not fully protected by galvanization. The embedding concrete protects these beam ends against corrosion.
  • the beams 3 In cross section the beams 3 enclose an upper hollow space 34 and a lower hollow space 35. Both hollow spaces 34, 35 extend in longitudinal direction of the beam 3 over the full length of the beam 3.
  • the upper hollow space 34 is triangular in cross section and comprises an upper surface 36 which is substantially horizontal in use and two symmetrically arranged side walls 37, 38, both converging downwardly under an angle of about 45 degrees with the upper surface and under a 90 degrees angle with each other.
  • the lower hollow space 35 comprises a lower surface 39 which is substantially horizontal in use and two symmetrically arranged side walls 40, 41, both converging upwardly under an angle of about 45 degrees with the lower surface 39 and under a 90 degrees angle with each other.
  • the lower surface 39 of the lower hollow space 35 borders the lower side 42 of the beam 3.
  • the lower side 42 of the beam 3 extends at both lateral sides of the lower surface 39 of the lower hollow space 35 to form the support surfaces 5 for supporting the blocks 2.
  • the lower surface 39 of the lower hollow space 35 forms the middle section of the lower side 42 of the beam 3 and spans about 10 - 50 %, e.g., about 25 - 40 %, e.g., about one third of the lower side 42.
  • the 90 degrees angular points 43, 44 of the upper and lower hollow spaces 34, 35 point towards each other.
  • a web 45 connects these two points 43, 44.
  • the web 45 is substantially vertical.
  • the cross section of the beam 3 is substantially symmetrical, with a symmetry axis coinciding with the vertical axis of the web 45.
  • the upper hollow space 34 is larger than the lower hollow space 35.
  • the width of the upper surface 36 of the upper hollow space 34 can be about 1,5 - 3 times, e.g. about 2 times the width of the lower surface 39 of the lower hollow space 35.
  • the web 45 comprises a lower section 46 and an upper section 47.
  • the lower section 46 is located between two adjacent blocks 2, while the upper section 47 is embedded in the concrete layer 4.
  • the overlapping ends 32, 33 of the metal sheet 31 are positioned in the upper section 47 of the web 45.
  • the upper section 47 of the web 45 is provided with local deformations, such as spherical impressions 48.
  • top surfaces 36 of the beams 3 protrude above the blocks 2.
  • a metallic reinforcement mesh 49 rests on the top surfaces 36 of the beams 3 (see Figure 1 ).
  • the mesh 49 is fully embedded in the concrete layer 4.
  • the disclosed geometry makes it possible to use beams 3 weighing 7,5 kg/m or even less and still having sufficient load capacity avoiding the need to use auxiliary supports during assembly of the floor.
  • the load capacity of the beams 3 can be sufficient to allow workmen to walk over the blocks 2 resting on the support surfaces 5 of the beams 3 before the concrete is poured. Hence, during assembly the beams 3 only need to be supported at positions where the final floor is supported after hardening.
  • the blocks 2 are made of an isolating material, such as expanded polystyrene, EPS.
  • the blocks 2 comprises a middle section 21 with a rectangular cross section bordered by two downwardly slanting longitudinal edges 22, 23 both provided with a shoulder 24 resting on the support surfaces 5 of the beans 3.
  • One longitudinal side 22 is provided with a lateral extension 25 extending below the shoulder 24, fully covering the lower side 42 of the beam 3 and abutting the lower side of the slanting edge 23 of and adjacent block 2. This way, the isolation layer formed by the blocks 2 is not interrupted by the beams 3 and the formation of thermal bridges can effectively be prevented.
  • the floor 1 is finished with a screed top layer 26.
  • the outer end 27 of the beam rests on a foundation 28 where it faces a wall section 29.
  • a gap 30 between the outer end 27 and the wall section 29 ensures that the outer end 27 of the beam 3 is fully embedded in the concrete layer 4.
  • FIG 4 shows an alternative embodiment of a floor 50 according to the invention. Parts which are the same as in the embodiment of Figure 1 are indicated with the same referential numbers.
  • Beams 3 comprise support surfaces 5 carrying blocks 51 formed by curved shells 51, e.g., of a concrete or plastic material. The shells 51 and beams 3 are covered by a concrete layer 4 finished by a screed top layer 25.
  • the lower side surface 39 of the lower hollow space 35 of the beams 3 is provided with fastening elements 52 for a ceiling element 53.
  • the lower surface 39 can also be used for fastening other constructional elements, such as piping and the like.
  • pipe lines 54 are arranged between the ceiling 53 and the shells 51.
