Definitions

  • This invention relates to a floor slab member consisting of an upper slab and a lower slab made of reinforced or non-reinforced concrete and interconnected by intermediate concrete coupling members between which there are provided concreteless spaces formed by a mould, as well as a method of manufacturing such a floor slab member.
  • the floor is to be composed of solid prefabricated slabs, or preferably of channel slabs from the viewpoint of saving weight, which can be deemed to be composed of an upper and a lower slab interconnected at regular intervals by substantially vertical longitudinal walls, thus producing a slab with a multiple of hollow longitudinal channels.
  • the undersides of these members too, may be covered with insulating material.
  • channel slabs are to be preferred.
  • Such channel slabs are normally made by extruding concrete through a nozzle, with the hollow channels being formed by means of sliding cores.
  • This manufacturing method requires highly capital-intensive investments on account of the expensive, relatively complicated installations and the required labour- intensive maintenance thereof.
  • This manufacturing method also entails the formation of relatively broad coupling members widening towards the upper and lower slab, at least coupling members that are more voluminous than is required constructively.
  • a floor slab member of the above described type in accordance with the first part of claim 1 is known from FR-A-1,533,735.
  • the mould herein is composed of plurality of cross-vault-shaped, metal members, so that a slab member is obtained having a clarity with columnar discontinuities which extends in two directions.
  • the mould elements are not only relatively heavy and expensive, but moreover require elaborate and time-consuming operations in placing and interconnecting them. These operations are rendered yet more difficult by the required reinforcing rods extending from the lower slab through the coupling members into the upper slab, which rods are moreover positioned at an angle, and at least partly overlap the mould elements to be placed subsequently.
  • a floor slab member of the above type characterized in that the mould comprises sidewalls extending longitudinally of the floor slab member for forming coupling members having the shape of continuous longitudinal side edges between upper and lower slab, and has openings contiguous with wall portions of the mould, said wall portions extending substantially perpendicular to the plane of the floor slab member, a number of which wall portions, like the sidewalls, having a height equal to that of the coupling members.
  • the mould during the casting and the hardening of the concrete provides the required supporting capacity, so that it can be constructed optimally and as light as possible, in particular as regards the volume of the coupling members, so that no allowance has to be made for the behaviour of the concrete during the manufacture and hardening of the floor slab member.
  • the application of a reinforcement in the coupling members can be omitted, since the continuous longitudinal sidewalls are to be dimensioned in such a manner that any loads, in particular transverse forces, can be properly taken up and transmitted, which renders the manufacture of the floor slab members considerably simpler and less expensive.
  • the coupling members defined by the openings in the mould are mainly adapted for taking up and transmitting any local point loads exerted e.g. by a cupboard leg or the like.
  • the mould for the entire floor slab member comprises a single member, this is easy to be transported, stored, handled and placed due to its one-piece condition. Moreover, however, no expensive and complicated apparatus are required.
  • the mould can be manufactured inexpensively as a simple compression-moulded, injection-moulded or cast piece from a relatively light material e.g. when in accordance with a further embodiment of the invention, the mould is a solid foam-plastic body having openings for the coupling members, which also enhances the insulating properties of the floor slab member.
  • the mould may also be made of a different material, such as plastic- coated cardboard or papier maché, in which case it is to be preferred that the mould comprises a hollow, open box-shaped body having ribs or ridges for surrounding the openings for the coupling members and for forming possible stiffening members.
  • the mould is made from a foam-plastic material by a moulding process, so that, relative to the solid embodiment, a substantial saving in tempex can be obtained, however entailing slightly higher manufacturing cost and changed insulating properties.
  • the moulds are provided with cross-sidewalls, which also enhances a closure of the cavities adjacent the cross side edges of the floor slab member.
  • the sidewalls and wall portions of the mould comprise bent foot portions pointing away from the coupling members.
  • the angle between a sidewall or a wall portion of the mould and the slab plane thereof exceeds 90°, the mould can be easily removed from its manufacturing mould, while the possibility of nesting a plurality of moulds is also advantageous during transport and storage of the moulds.
  • a strong, actually continuous coupling member connection between upper and lower slab, with preservation of the advantages of a one-piece mould, is obtained according to a further embodiment of the invention when the coupling members consist of longitudinally extending ribs having a length smaller than that of the floor slab member and a height equal to that of the longitudinal side edges, and of connecting ribs extending between the longitudinal ribs, having a height about equal to half the height of the longitudinal side edges, with the longitudinal ribs, viewed in longitudinal direction, being arranged so as not to link up with each other, and the end of a longitudinal rib being connected by means of a connecting rib to the ends of two longitudinal ribs arranged so as not to link up with each other.
  • a relatively simple rib pattern can be obtained when in accordance with a further preferred embodiment of the invention the longitudinal ribs, viewed in longitudinal direction, are arranged in offset relationship relatively to each other in such a manner that a next longitudinal rib is positioned centrally between the preceding adjoining longitudinal ribs.
  • the connecting ribs extend transversely to the longitudinal ribs.
  • pairs of connecting ribs link up in V-shaped relationship with the end of a longitudinal rib.
  • a sheet of foam plastic is preferably adhered to the underside of the lower slab.
  • the advantage of such a construction is that when e.g. in the prior art floor slab members, an insulating layer thickness of 5 cm is required, resulting in a sheet 5 cm thick underneath the known floor slab member, now a slab 3 cm thick will be sufficient by designing the mould with a wall thickness of 2 cm.
  • the present invention also relates to a method of manufacturing such floor slab members.
  • This can be effected in a very simple and relatively inexpensive manner, also as regards the apparatus to be used, in that in accordance with the invention a layer of concrete having the thickness of the lower slab is poured on a box-shaped form having a floor area equal to that of the floor slab member to be manufactured, and the mould is positioned on the lower slab with the longitudinal side edges and the wall portions around the openings directed downwardly while, with or without the use of a spacer member, the side edge of the mould is placed at a distance corresponding to the thickness of the longitudinal side edge to be formed from the sidewall of the form, concrete is poured on said mould until the coupling members and the upper slab are formed, and, after hardening the form is removed.
  • Figs. 1 and 2 show a floor slab member 1 composed of a lower slab 2 and an upper slab 3 interconnected by longitudinal side edges 4 and coupling members 5 in the form of columns of circular cross-section.
  • the space between the concrete portions 2-5 is filled up with a mould 6 consisting of a solid block of a synthetic plastics material having openings for the coupling members 5 and which, in fact, defines the internal form of the floor slab members during their manufacture.
  • the mould may also be formed as a flat sheet material 7 from which project on one side sidewall portions 8 and tube portions 9 over a height equal to the desired distance between lower and upper slab, while moreover between the sidewall and/or tube portions, there may be provided reinforcing or stiffening ridges or ribs, so that a floor slab member as shown in Fig. 2a is produced.
  • the columns 5 are positioned in a rectangular lattice pattern, but this may also be any other pattern as long as the vertical fixation between lower slab 1 and upper slab 2 is ensured.
  • the longitudinal side edges 4 have such a width that any transverse forces can be taken up and transmitted to further structural members in the desired manner.
  • Figs. 3-6 illustrate a floor slab member 10, which just as the floor slab member 1, is fitted with a lower slab 11, an upper slab 12 and longitudinal side edges 13.
  • this second embodiment there are provided two types of coupling members in the form of longitudinal ribs 14 having a height equal to that of the longitudinal side edges 13 and of cross ribs having approximately half the height of the longitudinal side edges 13, with the longitudinal ribs 14 linking up both with the lower slab 11 and with the upper slab 12, but the cross ribs 15 only with the upper slab 12.
  • the longitudinal ribs 14 are offset longitudinally relative to one another, with the longitudinal ribs 14, as viewed in transverse direction, overlapping one another along a distance equal to the width of a cross rib 13, there is formed a cavity 16 comprising a plurality of compartments which are all in open communication with each other by means of passages between the longitudinal ribs 14 and underneath the cross ribs 15.
  • the cavity 16 is bounded on the one end by the top of the lower slab 11 and on the other end by a mould 17 abutting against the bottom of the upper slab 11, the sidewalls of the longitudinal ribs 14, the side and lower walls of the cross ribs 15 and the inside of the longitudinal side edges 13.
  • a further wall portion of the mould 17 shuts off the transverse side edges.
  • FIG. 6 is a perspective view of a part of the mould 17 with the continuous longitudinal slots 18 being adapted to form the longitudinal ribs 14 and the troughed cross slots 19 for forming the cross ribs 15.
  • the mould is a one-piece member, since all «blocks» are interconnected by the lower wall of the trough of the cross slots 19.
  • Fig. 7 shows a floor slab member 20 representing a third embodiment, comprising a lower slab 21, an upper slab, not shown, longitudinal side edges 22, longitudinal ribs 23, connecting ribs 24 and a mould 25.
  • the longitudinal ribs 23 have a height equal to that of the longitudinal side edges 22, while the height of the connecting ribs 24 is half this height, with the connecting ribs 24 linking up with the upper slab.
  • the longitudinal connecting ribs pattern is such that two connecting ribs 24 extend in the form of a V from each end of a longitudinal rib 23, each of said connecting ribs, at the end of a successive offset longitudinal rib 23, meeting in the form of a V a connecting rib 24 extending from a longitudinal rib juxtaposed to said longitudinal rib 24.
  • a cavity composed of a plurality of compartments which are all in open communication with each other by means of passages underneath the connecting ribs 24, which means that the mould 25 can be a one-piece member.
  • Fig. 8 shows a floor slab member 30 adapted in particular to form a ground level floor.
  • the construction of this member can be compared with that shown in Figs. 1 and 2 or Figs. 3-5, be it that mould 31 is made of insulating material and has a wall thickness larger than that of the mould 7 or 17.
  • a plate 33 of insulating material is attached to the bottom of the lower slab 32. The thickness of the total layer of insulating material can be deemed to be the sum of the wall thickness of the mould 31 and the thickness of the layer of the plate 33.
  • the floor slab member according to the invention is its relatively light weight and hence relatively low material cost and its convenience and ease in handling.
  • a further very important advantage is the simple manner in which the floor slab member can be manufactured, notably without the use of expensive, complicated and maintenance-intensive apparatus.
  • the starting point for manufacturing a floor slab member according to the invention may be a box-shaped form 40, as diagrammatically shown in Fig. 9.
  • a lower slab 41 is cast in said form 40, after which mould 42 is positioned.
  • the latter may or may not be done by means of spacer members having a width of a longitudinal side edge to be formed.
  • concrete is again cast into the form 40 on and along the mould 42 in a quantity corresponding with the volume of the upper slab, longitudinal side edges and coupling members to be formed.
  • a reinforcement may be placed in position for each of the members to be formed prior to the casting thereof.
  • a floor slab member 30 according to Fig. 8 it is to be preferred to first install a layer of insulating material in form 40 before the lower slab 41 is cast. Casting concrete on such sheet or layer immediately results in proper bonding between the sheet or layer and the lower slab.
  • the columns and ribs patterns shown in the Figures should be seen as examples only, which can be varied in many ways.
  • the floor slab members may, if desired, be provided with cross side edges by a suitable design of the mould, while depending on the desired insulating properties, also the floor slab member shown in Figs. 3-6, 7 or 8 can be made with a mould filling up the entire cavity, as shown in Figs. 1 and 2. It is also possible to use continuous channel- shaped slots in the mould for receiving continuous reinforcing wires, which slots may extend either longitudinally or transversely.
  • edges of the mould may be placed on the concrete cast for the lower slab with foot members in the form of thickenings, bent wall portions or the like.
