Definitions
- the invention relates to a method for manufacturing a floor of concrete, using prefab elements.
- the invention furthermore relates to a prefab shuttering floor for said method.
- FR-A-671.568 discloses a reinforced concrete floor slab comprising an array of two-part concretes boxes, the upper parts of the boxes being connected to one another by portal forming gates.
- a prefab floor slab consisting of a concrete base plate having a reinforcement in it, having lattice girders extending in a main direction and protruding from the upper side.
- the floor slabs are placed on walls, beams and/or columns that have already been realised, and supported in the field by means of props. After that an upper reinforcement net is placed on the lattice girders where necessary, and subsequently the floor is final cast with concrete.
- German patent application 30 45 663 suggests pressing elongated, inverted channel-shaped displacement bodies of a lightweight material, such as PS, in the concrete of the base plate that has not hardened yet, between the lattice girders. After that the channels in which the lattice girders extend are filled with concrete. The floor slab thus obtained is transported to the construction site, placed there and subsequently the upper reinforcement is arranged, after which the floor is final cast.
- a lightweight material such as PS
- the final cast floor will furthermore only have a concrete connection between the base plate having reinforcement and the poured plate having upper reinforcement, said connection extending transverse to the channels at the location of the ends of the elongated bodies. As a result the bending strength in a direction transverse to the channels will be small.
- a further object of the invention is to provide a plate of the type mentioned in the preamble in which lines can easily be incorporated and remain accessible and interchangeable after pouring the floor.
- a further object of the invention is to provide a plate of the type mentioned in the preamble which is easy to manufacture and dimensionally stable.
- the invention from one aspect provides a method for manufacturing a floor slab from concrete, starting from a concrete base plate having a reinforcement in it, according to claim 1.
- the invention provides a shuttering slab for floors, comprising a base plate having reinforcement according to claim 19.
- the boxes when placed can be placed at a known distance from each other for forming spaces to be filled with concrete, whereas the internal spaces of the boxes remain connected to each other so that lines can be passed through, the internal spaces of the gate connections and boxes remaining substantially free from concrete.
- the boxes in the first direction, are placed against each other to form second gate connections, at least one gate being one gate protruding from a side wall, preferably in the shape of a portal.
- the second gate connections here can preferably in a second direction transverse to the first direction, form a boundary for spaces to be filled with concrete. They as it were form a partition.
- the concrete when pouring concrete for the spaces of the lattice girders, can spread in the first direction, but it is retained in the second direction.
- the second gate connections thus can form a barrier for separating a space extending in a first direction, adjacent to the lattice girder, from concrete.
- the concrete can be kept limited to the locations selected for the lattice girders.
- the second gate connections are provided with an elevation extending above the actual gate connection, so that the first and second gate connections can be similarly shaped and a larger freedom is achieved in the placing of the boxes.
- the first and second gate connections are of equal height and/or cross-section.
- first and/or second gate connections are formed by two gates protruding from the side walls in question of the boxes in question, which further increases the placing possibilities.
- partitions are provided between boxes consecutive in the direction parallel to the lattice girders, for forming channels running in that direction with the box walls running in that direction, the lattice girders being provided in those channels, the channels being filled with concrete. In this way spaces extending in transverse direction are kept free which during final casting are filled with concrete and thus form a stiffening of the floor slab in transverse direction.
- boxes are used with gates oriented in a direction parallel to the lattice girders and/or with gates oriented in a direction perpendicular to the lattice girders.
- boxes offer advantages for passing through lines.
- the use of boxes with gates oriented in a direction (the first direction) parallel to the channels is advantageous for passing through lines preserving the transverse reinforcement.
- boxes are used here having gates oriented in a (second) direction perpendicular to the channels, so that laying lines within the slab, in transverse direction is facilitated.
- the matrix of hollow boxes, connected to each other in two directions perpendicular to each other, offers a large number of possibilities for drawing lines in several directions.
- lattice girders are supported on the gates, not only material for lattice girders can be saved on (it may have a lower height per se), but it is also ensured that they extend upwards to the same extent with respect to the boxes, whichever way they have been placed.
- the lattice girders are placed in order to extend to above the boxes, so that the upper reinforcement can remain free from the boxes in a certain manner.
- Preferably boxes having a rectangular, preferably a square, cross-section are used, to that the quantity of concrete to be poured can be kept small. Moreover, when making the slab a longer time, until the placing of the lattice girders, is available for selecting the channel direction, which may be particularly advantageous in case of square plates.
- boxes having an open bottom are used.
- the boxes may be provided with fastening feet or fastening lips for placing the boxes over the base plate reinforcement, free from it.
- the fastening feet make it possible to place the boxes prior to pouring the base plate, as a result of which the upper sides of the boxes will lie equally, as well as the lattice girders.
- boxes are used having an upper wall, of which at least a part can be removed, which part preferably is surrounded by a circumferential weakening line.
- the floor slab is placed in situ and an upper reinforcement is laid at a distance above the highest plane of the boxes, after which the floor is final cast with concrete.
- a lid having a raised circumferential edge is placed on the upper wall -that may or may not be opened- of one or more boxes, the space within the circumferential edge being filled during final casting, the edge extending to the upper surface of concrete after final casting the floor with concrete.
- the space within the boxes then also remains accessible after completion of the construction, either because the upper wall was already opened or by cutting the upper wall open, as already explained.
- the upper reinforcement is not laid then at the location of those boxes, in order to keep the accessibility when laying the lines and afterwards, after pouring the floor, optimal.
- the invention provides a method for manufacturing a floor slab from concrete, starting from a concrete base plate having a reinforcement in it, a number of boxes being positioned on the base plate, which boxes have been provided with side walls and gates formed in at least two opposite side walls, adjacent boxes being contiguous with their gates to form a gate connection between those two adjacent boxes, a lid having a raised circumferential edge being placed on the upper wall -that may or may not be opened- of one or more boxes, the space within the circumferential edge being filled during final casting, the edge extending to the upper surface of concrete after final casting the floor with concrete.
- the space within the boxes then also remains accessible after completion of the construction, either because the upper wall was already opened or by cutting the upper wall open, as already explained.
- the boxes are used which have an upper wall, of which at least a part can be removed, which part preferably is surrounded by a circumferential weakening line.
- the lid supports on the box near a continuously circular circumferential edge of the upper wall, preferably at the location of the weakening line. In this way it is prevented that mortar penetrates the space between the lid and the upper wall (when still present) or from under the lid, into the box.
- the floor slab is placed in the work and an upper reinforcement is laid at a distance above the highest plane of the boxes, after which the floor is final cast with concrete.
- the upper reinforcement is not arranged at the location of boxes to be provided with a lid, in order to keep the accessibility when laying lines and afterwards, after pouring the floor, optimal.
- the box 1 shown in figure 1 has been manufactured of synthetic material (although other materials, such as metal or compressed wood fibres are also possible), and has a circumferential wall 2, having four sides of equal length defining a square shape, and a lid 3 placed on the upper edge of the circumferential wall 2.
- the lid 3 can be taken off in order to gain access to the inside of the box 1 and has a reinforcement 21 and a circumferential edge 20 that hangs down.
- the lid 3 may possibly be placed inverted, as shown in figure 2 , which will be further gone into.
- the circumferential wall 2 has a square cross-section which is smaller than at the bottom, so that the box has a slightly tapering shape.
- a gate 6 is formed in the middle below, by means of a portal-shaped integrally formed part 4, having turned flange 5.
- the flange 5 is situated in a surface perpendicular to the upper surface 10 of lid 3, and also perpendicular to the -open- bottom surface of the box 1.
- the portals 4 are trapezium-shaped. Due to the tapering shape of the circumferential wall 2 of the box it is achieved that the boxes can be nested or stacked.
- the circumferential wall is in each side furthermore provided with an integrally formed pendent foot or lip 8 that protrudes downwards from the hollow edge 7 of the circumferential wall 2.
- the shuttering slab 11 is shown, comprising a concrete base plate 12, in which bottom reinforcement 13 has been incorporated which will be grid-shaped.
- the boxes 1 Prior to pouring the base plate the boxes 1 have been positioned, in a regular matrix, as can be seen in figure 3 .
- the lips 8 have been placed on the mould bottom for the base plate 12. The lips 8 are high to such an extent that the lower edge 7 of the box 1 remains free from the reinforcement 13.
- the boxes can be placed after pouring the base plate when the concrete has not hardened yet.
- the boxes 1 have been placed such that gates 6 are in line with each other, the flanges 5 of the portals 4 of adjacent boxes 1 being placed tightly against each other and meeting each other in a vertical plane.
- lattice girders 16 have been placed in a parallel arrangement, the lattice girders 16 supporting on the upper sides of the portals 4.
- the lattice girders 16 extend above the longitudinal ribs 18 and also above the lids 3 of the boxes 1.
- the shuttering floor 11 is then ready for transportation to the work, and to be placed there on permanent and possibly temporary supports.
- the shuttering slab 11 Because of the longitudinal ribs 18 the shuttering slab 11 has a considerable strength against bending through, so that (temporary) propping is not necessary or only to a limited extent.
- a box 1 On the right hand side in figure 4 a box 1 is shown, the lid 3 of which has been placed inverted.
- the circumferential edge 20 extends to in the upper surface of the final cast or finished floor.
- the space within the circumferential edge 20 has been poured with the concrete of the layer 19, possibly after the outer side of the edge 20 has been provided with a de-adhesion agent.
- the lid 3 cannot only be easily removed in the shuttering floor supplied in the work for drawing lines and installation of lines, but this can also be done after completion of the floor, for inspection or making changes in the line system. It is possible here -in case of otherwise the same boxes- to use lids having edges 20 of different heights, adjusted to the thickness of the floor.
- the boxes 1 do not only have a function in saving on weight and material for the plate, but also function as passage means for lines which remain easily accessible and adjustable -possibly even after completion of the floor-, and have the function of shuttering for forming longitudinal ribs in the prefab shuttering slab 11.
- the box 101 made of synthetic material, shown in figures 5 and further, has a substantially square horizontal cross-section having a circumferential surface 102 formed by two opposite side walls 102a and two opposite side walls 102b.
- the upper wall 103 is closed and comprises a circular central portion 131, surrounded by a raised edge 132, also vide the cross-section shown in figure 6D .
- the upper wall 103 changes via curved planes into side walls 102a, 102b, which substantially are each situated in an almost vertical plane, but for reasons of nesting the boxes one in the other, run slightly upwardly inclined to the inside.
- the two opposite side walls 102a have each been provided with a gate 106a, surrounded by a portal 104a protruding from the side wall 102a.
- the portal 104a has a flat upper side 110a, and two sides 110, which in horizontal cross-section have been formed V-shaped (110c) to the inside. Said V-shape forms a pilot/orienting means for lines during their insertion, for correction in alignment when adjacent boxes are not exactly aligned.
- a circumferential, compliant flange 105 has been formed which extends outwardly inclined.
- the gates 106b in the two other side walls 102b that are also opposite each other are similarly shaped, so also with a portal 104b, the difference being that on top of the upper side 110b an elevation 109 has been integrally formed, both at that upper side 110b and at the actual side wall 102b.
- the elevation 109 has been provided with a protruding strip 109a, extending to near the flange 105.
- the raised circumferential edge 132 has two tops 133, 134, which in between them define a recess 135 running in circumferential direction.
- the tops 133, 134 may serve as guide for a cutting tool used to cut through the bottom of the recess 135, in order to thus be able to remove the central part 131 of the box 101, as already mentioned above in the discussion of the other embodiment of a box according to the invention, to facilitate installation operations.
- the lid 120 After removal of the central part 131 the lid 120, shown in figure 7 , can be placed on it. As can be seen in figure 7 the lid 120 may however also be placed on the upper wall of the box 101, when its central part 131 has not been removed. In both cases the lid 120 supports on the raised edge 132 in a mortar-tight manner, which edge, when the central part 131 has indeed been removed, ends at top 134.
- the lid has been made of the same synthetic material as the box and has a step-shaped, circumferential inclined raised edge 121 and a bottom part 123 which follows the curve of the central part 131.
- the bottom 123 has been provided with an elevation 122 suitable for engagement by the hand.
- the elevation 122 has been provided with a recess 124, in which a reinforcing rod can be laid, which as a result is stabilised in vertical downward direction and also in both sideward directions.
- the boxes 101 can be placed in the manufacturing of a shuttering slab, in a manner comparable to the boxes 1 of figures 1-4 .
- the flanges 105 of gates/portals 106/104 to be placed against each other are pressed against each other, the flanges 105 being slightly compliant, and an almost concrete-tight connection between both portals 104 has been realised.
- the flanges 105 stand away slightly outwardly inclined, considered from the centre of the box 101 in question, the sealing can be realised within a certain tolerance range. As a result a sealing of the internal space of the portal 104 and the boxes 101 is ensured also in case of some measure or grid deviation.
- the lattice girders 116 can be placed, which takes place on the upper side 110a of the portals 104a. Subsequently the spaces 118 are poured with concrete, until the concrete reaches the upper side of the elevations 109. Because of the elevation 109 and the integrally formed strips 109a it is prevented that the concrete, in the drawing seen to the right and to the left, can flow away, so that the space 118 situated there, if so desired, can be kept free from concrete in the shuttering slab.
- the portals 104b, with elevations 109b, here function as partitions, comparable to the partitions 8 in the embodiment of the figures 1-4 .
