Definitions

  • the invention relates to a floor part as a part for a floor construction such as an insulation floor, a floor construction, and a method for constructing an insulation floor, and a building provided with an insulation floor.
  • a floor is provided with subfloor-boards and girders provided with one or more bearing surfaces for bearing the subfloor-boards, and a layer of concrete that constructionally connects the girders and covers the subfloor-boards.
  • At least a part of the girders consists of a girder material that in case of the same bearing capacity of the girder results in a lower weight per running unit of length of the girder than reinforced or prestressed concrete does.
  • the girders may for instance be made of a synthetic material, such as a composite, or of a sheet metal, shaped into the desired profile.
  • US6085479 describes a premanufactured structural building panel for promoting the efficient construction of the exterior wall members or the horizontal root and ceiling walls of a building having improved insulation, sound absorption, fire retardant and structural properties.
  • the premanufactured structural building panels consist of a number of C-shaped structural channels.
  • the panels are provided with a fire retarding board secured to opposing angle members and a foam insulation member secured to the fire retarding board.
  • a plurality of retaining members are provided for additional structural support.
  • the structural panels are supported on wall support members and connected to each other in a side-by-side fashion to form an exterior wall member or an horizontal roof and ceiling wall of a building.
  • the panels are arranged such that the C-shaped channels are protected from conditions external to the building by a portion of the foam insulation members.
  • the invention provides a floor construction according to claim 1, and to a method for constructing an insulation floor in a building according to claim 13.
  • the floor part is used as insulation floor, in particular a ground floor insulation floor, in the construction of houses.
  • This floor concept will in one embodiment be used in particular in new builds, renovations, refurbishments and small extensions.
  • Prefab premanufactured
  • the floor parts comprise floor elements of an expanded synthetic material or a synthetic foam.
  • An example of such materials are expanded polyethylene (EPP), expanded polypropene (EPP), expanded polystyrene (EPS), polyurethane foam (PUR).
  • EPP expanded polyethylene
  • EPP expanded polypropene
  • EPS expanded polystyrene
  • PUR polyurethane foam
  • the floor elements are substantially block-shaped. As a result they can be fitted well into a building. It is of course possible to adapt outer ends to the building walls that are not straight.
  • the edges of the floor elements may be adapted so that the top surface and the profile parts provide a substantially flat top surface.
  • the top faces of the floor elements may at their longitudinal sides be provided with a recess for the flanges. As a result the top face of the floor parts can provide a flat surface.
  • the floor elements may be provided with a longitudinal groove for accommodating the flanges of the U-profile parts. A vertical cold bridge is thus avoided.
  • the longitudinal groove will have been arranged at least a few centimetres above the bottom face. Said groove will usually be fitting to the flange, optionally clamping it. A simple incision or longitudinal cut may suffice to accommodate a flange.
  • a similar effect of avoiding a vertical cold bridge can be achieved by means of a floor element of a first block-shaped floor element member having a thickness fitting between the flanges of a U-profile part.
  • the floor element furthermore comprises a second floor element member having a width adapted to the distance between the bodies of opposing U-profiles of a floor part.
  • the width of the second floor element member substantially corresponds with the width of a floor part.
  • a second floor element member may have a higher compression strength than the first floor element member.
  • a second floor element member may be shorter than the length of the first floor element member.
  • one or more second floor element members may extend between the support members.
  • a face of the second floor element member adjacent to the first floor element member may be provided with a recess for a flange.
  • the face of the first floor element member may be provided with a recess for a flange.
  • a recess could also be divided over both floor element members.
  • the U-profile parts are shape-retaining and in one embodiment made of metal.
  • Suitable metals are for instance iron and/or galvanised steel.
  • galvanised steel having a thickness of 0.5-2 mm is suitable, more in particular 0.7-1.5 mm.
  • Other materials providing a corresponding rigidity and strength may also be suitable.
  • galvanised steel is suitable.
  • the U-profile parts of abutting floor parts may be connected to each other back-to-back by means of snap members, or be connected by means of bolts or screws.
  • the invention furthermore relates to a floor construction comprising floor parts as described, comprising a series of floor parts in longitudinal direction adjacent to each other, wherein the U-profile parts in longitudinal direction extend beyond the floor elements, and wherein the floor construction furthermore comprises a circumferential formwork border provided with a support ledge for supporting the outer ends of the U-profile parts and with an upright edge.
  • the invention further relates to a method for constructing an insulation floor in a building for obtaining a floor construction as described, wherein the formwork border is attached to a part of a building, the floor parts are laid in longitudinal direction adjacent to each other with the body of one of the U-profile parts of a floor part against the body of one of the U-profile parts of a next floor part, back-to-back, for providing a continuous insulation floor, and with the outer ends of the U-profile parts that in longitudinal direction extend beyond the floor elements and that support on the support ledges.
  • the U-profile parts may first be connected to each other back-to-back, after which the floor elements of synthetic foam are placed in between them.
  • H-profiles can in fact be provided and floor elements of synthetic foam, the longitudinal sides of which extend fully or in part in between such H-profile parts.
  • the invention further relates to a floor part for an insulation floor for a ground floor for buildings, comprising a substantially block-shaped floor element of synthetic foam provided with a top and bottom face and opposing longitudinal sides, and wherein along the opposing longitudinal sides the floor element is provided with shape-retaining, substantially rectangular U-profile parts provided with a body and flanges, wherein the bodies abut the longitudinal sides, a flange abuts a top face, and a flange is embedded in the floor element spaced apart from the bottom face.
  • the floor construction makes a self-supporting, insulating floor possible.
  • the invention furthermore relates to a floor part provided with one or more of the characterising measures described in the attached description and/or shown in the attached drawings.
  • Figure 1 shows an example of a floor provided with a subfloor, in this case a bearing subfloor.
  • a subfloor in this case a bearing subfloor.
  • an insulating floor construction with floor parts 2 has been placed, and atop of it, partially interrupted, a finishing floor 6.
  • a finishing floor may for instance be a wooden flooring, or a (snap-together) laminate flooring, or a pressure layer of poured material such as concrete.
  • the floor parts 2 here comprise block-shaped floor elements 3 of synthetic foam. Alongside both longitudinal sides each floor element 3 is provided with a U-profile part 5.
  • the U-profile parts 5 have a body 7 and flanges 8.
  • the floor elements comprise a first floor element member 3 and a second floor element member 4.
  • a second floor element member 4 there is no or hardly any heat contact between the lowermost flanges 8 of the U-profiles 5 and the subfloor, and the environment. In that way a vertical cold bridge due to the U-profiles 5 is prevented.
  • the first floor element members 3 fit in between the flanges 8 of the U-profiles 5.
  • a material of the second floor element member 4 can be chosen to have a greater pressure resistance than the material of the first floor element member.
  • a floor element 3 is provided with opposing cuts or longitudinal grooves for accommodating one of the flanges 8 of a U-profile part 5.
  • the top surface of a floor element 3 is provided with projections 10.
  • the projections have a flat top face.
  • the projections 10 have here been arranged on a fixed grid, in this case a rectangular grid.
  • the diameter of the projections will usually be 5-20 cm, mostly 5-15 cm.
  • the height of the projections may be selected in between 1 and 3 cm.
  • Figure 3 shows a detail of figure 1 .
  • the floor parts 2 have not been arranged on a subfloor.
  • An example thereof is shown in figure 4 .
  • the outer ends of the U-profiles 5 are supported by construction members 15.
  • a floor part 2 here comprises a floor element 3, along both longitudinal sides provided with profile parts 5 extending beyond the floor parts.
  • the construction members 15 are a circumferential beam 15 or a small wall 15.
  • the chosen construction 1 further accelerates the method, can be used for various storeys in a building, and provides an accurate finishing height for an optional pressure layer by using a circumferential formwork border 12.
  • the formwork border 12 is made of the same material as the profile parts 5.
  • the formwork border 12 comprises an upright edge 13 and a support ledge 14.
  • Support ledge 14 can easily be placed on a supporting member such as the said circumferential beams of an interior wall.
  • a dampening layer may have been placed in between the construction and the support ledge 14.
  • the formwork border with the upright edge 13 can be secured to a wall and the support ledge 14 provides a ledge for the profile parts 5.
  • a separate bearing profile may also be screwed to the wall and the formwork border may then support thereon.
  • the profile parts 5 extend beyond the floor elements 3.
  • the floor elements 3 have here been provided with the longitudinal cut so that the flanges 8 of the profile parts 5 have been accommodated therein and the insulation extends beyond the profile parts and the profile parts do not form a cold bridge.
  • further layers can be applied for insulation, for instance rubber strips or parts of synthetic material.
  • the space in between the outer ends of floor elements 3 and the upright edge 13 of the formwork border 12 may be filled with insulation blocks 16.
  • intermediate spaces 17 have furthermore been left open.
  • the construction 1 has furthermore been provided with a floor, in this case a pressure layer 6 on which a finishing flooring such as parquet, laminate flooring or a carpet may be placed.
  • the pressure layer may be of a poured material, such as for instance concrete.
  • the intermediate spaces 17 can then be filled with the poured material so that support members 18 are created for additional bearing properties of the pressure layer.
  • a floor element 2 in one embodiment consists of a polystyrene foam (EPS) core enclosed on both sides by a metal U-profile 5.
  • EPS polystyrene foam
  • the thickness of the floor depends on the desired RC-value and the span and the load that will be on the floor. In a specific embodiment this floor has a thickness of 200 mm. By using various qualities of EPS, different RC-values can be achieved.
  • the width of the floor element is for instance 500 mm. Other widths can be made for fitting pieces.
  • the length of the floor element depends on the desired floor length of the building project and this may vary from 1.5 to 8 metres.
  • the metal U-profile is formed according to the specifications required according to the Dutch calculation rules for floor loads.
  • the present U-profile has a height of 200 mm with two flanges that are folded back of approximately 40 mm, but depending on the span, the required loading capacity, the width of the flanges, the thickness of the profile the height of the U-profile may vary.
