Definitions

  • This invention relates to a floor element comprising a bottom plate, which is made of a first concrete material and wherein the bottom plate forms a bottom layer of the floor element, and a first upper layer which is provided on top of the bottom layer and which comprises at least a first substantially plate-shaped upper module which is applied on top of a top plate surface of the bottom plate and connected thereto.
  • the invention further relates to a method for manufacturing a floor element and to a floor which comprises at least one floor element according to the present invention.
  • Prefabricated concrete floor elements have, since decades successfully been used in residential and non-residential building.
  • a floor is usually constructed by positioning a plurality of prefabricated concrete elements with their upright longitudinal sides against each other and with their mounting edges laying on supporting construction parts, such as walls and beams.
  • a covering or finishing layer is applied on top of the thus constructed floor.
  • the floor elements are usually made of reinforced and/or pre-stressed concrete.
  • pre-stressed concrete is preferred, because such floor elements can withstand higher loads compared to reinforced concrete floor elements.
  • the easy positioning and immediate ability of carrying loads renders the prefabricated concrete elements particularly suitably for a quick and efficient building of floors.
  • the concrete floor elements usually comprise a plurality of hollow channels which extend in longitudinal direction of the floor element.
  • Another method known in the art is to apply, on site, slots in the floor elements, to accommodate electric conduits, pipes and tubes.
  • the slots are obtained by locally removing part of the prefabricated elements.
  • the application of such slots after the floor elements have been produced substantially reduces the strength and bearing capacity of the floor, in particular in the case the slot extends in transversal direction of the floor element.
  • the floor must be supported at its bottom side and the slots need to be re-filled with concrete, after the conduits have been positioned into the grooves.
  • the application of slots in the already hardened concrete has the disadvantage that it is difficult and very time consuming and goes at the expense of the load bearing capacity of the floor element. Therefore, the person skilled in the art will usually choose for other building methods.
  • EP-B-1214483 and NL-1011955 describe two other methods for applying slots in floor elements.
  • EP-B-1214483 describes a hollow-core plate, which comprises a lower reinforced concrete flange, an upper concrete flange and concrete ribs connecting the lower and upper flange in such a way that a number of hollow channels are formed between the lower and upper flange.
  • the lower flange has a thickness which is larger than the thickness of the upper flange and is dimensioned such that the lower flange is capable of withstanding and transmitting transverse forces to the mounting edges of the hollow-core plate resting on the supporting construction parts.
  • At least one slot is formed in an upper part of the floor element, which is provided for receiving slots or electric wiring. The slot extends in horizontal direction at an angle with respect to the reinforcement and in height direction maximally as far as the lower flange.
  • the slot is formed during the manufacturing process of the hollow-core plate by removing a suitable amount of material from the still fresh concrete. After insertion of the appropriate conduits in the slots of the floor element, the slots are filled again with a less high quality material. The removal of concrete to form the slots risks to adversely affect the mechanical properties of the floor element. Other disadvantages of this method are that it is labour-intensive and that the slots have rough and irregular edges, which makes the placement of conduits in the slots more difficult.
  • NL1011955 describes a floor element with a plurality of adjacent longitudinal hollow channels.
  • a recess is provided in an upper part of the floor element, which can be used for receiving ducts or the same.
  • the recesses are formed by compressing part of the still fresh concrete and closing the hollow channels near the recess.
  • the recesses may extend in longitudinal or transversal direction of the floor element, over part of or the whole width of the floor element.
  • the thickness of the concrete floor parts surrounding the recess is substantially higher than the thickness of the concrete floor parts beneath and above the channels, such that the strength of the floor element is not adversely influenced by the formation of the recesses in the floor element.
  • the main disadvantages of this floor element are that compression of the still fresh concrete to form the recesses is labour-intensive and that the recesses have rough and irregular edges and surfaces, which makes the positioning of pipes and conduits in the recesses more difficult.
  • the known methods for applying slots in prefabricated floor elements during production of the floor element, have the disadvantage that they are labour-intensive because still fresh concrete needs to be removed or compressed and that the thus formed slots have rough and irregular edges and faces.
  • the in situ formation of slots in a pre-fabricated floor element may only be done by removing material from the prefabricated floor elements, which is labour-intensive since it involves removal of the already hardened concrete.
  • the existing methods involve the risk to adversely affect the strength and bearing capacity of the floor.
  • the floor element according to the present invention is characterized in that the first upper layer comprises a second substantially plate-shaped upper module, which is applied on top of the top plate surface of the bottom plate and connected thereto and wherein the first and the second upper module are positioned with respect to each other in such a way that at least one accessible slot is provided between them and wherein the position of the first and second upper module is adjustable to provide an adjustable slot.
  • the first upper layer comprises a second substantially plate-shaped upper module, which is applied on top of the top plate surface of the bottom plate and connected thereto and wherein the first and the second upper module are positioned with respect to each other in such a way that at least one accessible slot is provided between them and wherein the position of the first and second upper module is adjustable to provide an adjustable slot.
  • a floor element according to the present invention comprises at least three floor parts, being a bottom plate and a first and a second substantially plate-shaped upper module.
  • the floor element is constructed by applying at least the first and the second upper module on top of the bottom plate and connecting them thereto.
  • the floor element according to the present invention does not require material removal but to the contrary is built up modularly until it has attained the required shape, dimensions and bearing capacity to fulfill the desired functionality. Since no material needs to be removed, the individual floor elements keep their mechanical properties and load bearing capacity.
  • the at least first and second upper module are connected to the bottom plate, they form one structural and load-bearing unit and each floor part contributes to the load-bearing capacity of the floor element as a whole.
  • the connection between the first and second upper module with the bottom plate also allows a transfer of forces from the first and second upper module to the bottom plate and vice versa.
  • the connection between the first and second upper module with the bottom plate also assures that shearing forces between the bottom plate and the first and the second upper module are neutralized.
  • the bottom plate on the one hand and the at least first and second upper module on the other hand are manufactured as separate modules.
  • the positioning and connection of the at least first and second upper module with the bottom plate can be done in-situ on the construction site, but is preferably done in the factory where the floor parts are manufactured.
  • the floor element according to the present invention can be provided with slots in a very simple way by positioning the first and the second upper module appropriately with respect to each other and connecting them to the bottom plate.
  • the obtained slot is an adjustable slot, meaning that it may extend in any possible direction and may have any desired dimensions in height, width and depth and that the direction and dimensions can be adjusted and controlled after having manufactured the different floor parts, and this without having to break down or remove part of the material of the floor element.
  • the floor element according to the present does not require a different mould for every different required dimension or orientation of the slot.
  • Other advantages are that the manufacturing cost of the floor element may be decreased and that the functionality of the floor element can be easily adjusted.
  • the slot provided in the floor element according to the present invention is an accessible slot, meaning that the slot may be accessed from outside after the floor element has been build up.
  • the slots have a sharp finishing.
  • the slots are limited by the upright sides of the first and second upper module and part of the top surface of the bottom plate. Since the bottom plate and the first and second upper module are prefabricated floor parts, they are usually limited by sharp sides and surfaces. This sharp finishing and lining of the slots makes it easier to place elements, such as conduits or wiring, into the slots.
  • the slot applied in the floor element according to the present invention is suitable for taking up conditioning elements, such as electrical wirings or heating and/or cooling ducts or any other elements considered suitable by the person skilled in the art.
  • the dimensions, orientation and position of the slot can be controlled and adjusted, depending on the number of conditioning elements to be inserted into the slot and depending on the required position and orientation of the conditioning elements. Because the slot is accessible from outside, the insertion of the conditioning elements into the slot can be done easily, without having to break or remove part of the floor element. In case one or more of the inserted elements is damaged, the elements can be accessed and replaced easily, without having to replace or break down the entire floor element. Moreover, the sharp finishing and lining of the slot makes it easier to insert elements, such as conduits or wiring, into the slots, without the risk of getting hurt by the rough edges of the slot.
  • the top surface of the bottom plate and the bottom surface of the first and/or second upper module preferably comprise cooperating positioning means with a complementary shape.
  • the positioning means may for instance comprises a cooperating ridge and groove with a complementary shape, a protrusion and recess, a tongue and groove or a combination of two or more thereof or any other shape considered suitable by the person skilled in the art. These positioning means allow increasing the accuracy of the positioning of the at least first and second upper module on the bottom plate and increase the transfer of forces to the bottom plate.
  • the floor element 1 comprises at least three floor parts, namely a bottom plate 2 and a first 3 and a second 4 substantially plate-shaped upper module.
  • the bottom plate 2 is delimited by a top 5 and bottom 6 plate surface, two upright longitudinal sides 7, 8 and two upright transverse sides 9, 10.
  • the first substantially plate-shaped upper module 3 is delimited by a top 11 and a bottom 12 module surface, two upright longitudinal sides 13, 14 and two upright transverse sides 15, 16.
  • the first upper module 3 is applied with its bottom module surface 12 on the top plate surface 5 of the bottom plate 2 and is connected thereto.
  • the second substantially plate-shaped upper module comprises a top 17 and a bottom module surface 18, two upright longitudinal sides 19, 20 and two upright transverse sides 21, 22.
  • the second upper module 4 is, similarly to the first upper module 3, applied with its bottom module surface 18 on the top plate surface 5 of the bottom plate 2 and is connected thereto.
  • the bottom plate 2 forms a bottom layer of the floor element.
  • the first and second upper modules form a first upper layer of the floor element.
  • the thickness of the first 3 and second 4 upper modules may be the same or different, but is preferably the same, such that the application of additional layers on top of the first upper layer can be done in an easier way.
  • the first 3 and the second 4 module are positioned with respect to each other in such a way that at least one accessible and adjustable slot is provided in between them.
  • the slots are preferably provided to receive first conduit elements, which can be inserted in a very easy way (not shown).
  • first conduit elements can be any type of ducts considered suitable by the person skilled in the art, such as electrical wirings, ducts, elements for conditioning the floor element, such as elements for heating or cooling the floor element, or a combination thereof.
  • the position of the first and the second upper module with respect to each other is adjustable.
  • the thus formed slot is easily adjustable.
  • adjustable is meant that the position and the dimension of the slot can be changed without needing to remove part of the floor element or without having to perform any other labour intensive activities.
  • the position and dimensions of the slot can be changed. This change can be performed in the factory or on site, such that the floor element can be adjusted depending on the needs on the construction site.
  • the bottom plate is made of a first concrete material.
  • This first concrete material can be the conventionally used concrete, a mixture of granular materials, natural or artificial, which are bounded with a binding agent, such as cement, polymers or asphalt, to a stone-like material.
  • a suitable classification with respect to concrete materials is a classification according to weight by volume, because a lot of properties of concrete materials are directly or indirectly coupled to the weight by volume.
  • the concrete standard NEN-EN 206-1 distinguishes, based on (artificial, dry) volume by weight, the following concrete materials: light concrete with a volume by weight of 200-2000 kg/m 3 , normal concrete with a volume by weight of 2000 - 2600 kg/ m 3 and heavy concrete with a volume by weight exceeding 2600 kg/m 3 .
  • the first concrete material of the bottom plate 2 of the floor element preferably comprises reinforcement means 29 as is shown in figure 1 .
  • the bottom plate 2 of the floor element is therefore preferably made of reinforced concrete. More preferably, the bottom plate is made of pre-stressed concrete, which leads to floor element which is able to withstand even higher loads compared to floor elements made of pre-stressed concrete.
  • the edges of the floor element may additionally be provided with reinforcement elements 30 as is shown in figure 1 to allow even higher loads on the mounting edges of the floor element.
  • the bottom plate may be a massive plate or a so-called hollow-core plate, i.e. a plate which comprises a number of hollow channels which extend in longitudinal direction of the floor element, leading to a material- and weight reduction.
  • the reinforcement means 29 may extend above or beneath or above as well as beneath the hollow channels 28.
  • the bottom plate may also be provided with second conduit elements which are incorporated in the first concrete material. These second conduit elements can be the same or differ from the first conduit elements provided in the slots of the floor element.
  • the second conduit elements can be provided above or beneath the reinforcement and above or beneath the hollow channels.
  • the incorporated conduit elements may or may not be connected to the reinforcement means 29.
  • the modular build up of the floor element allows manufacturing the first 3 and the second 4 upper module in another material than concrete.
  • the first 3 and the second 4 upper module may for instance be made of a composite material, a composite material which comprises a foam core, a fiber reinforced plastic material, a fiber reinforced composite material, or any other material which is considered suitable by the person skilled in the art.
  • the fibers may be metal fibers, natural fibers, plastic fibers, glass fibers or any other type of fibers considered suitable by the person skilled in the art.
  • the material of the first 3 and second 4 upper module may fulfill an additional functionality, for instance an acoustic insulating, a thermal insulating or a vibration-damping functionality.
  • the use of another material than concrete allows building up a floor with a decreased weight.
  • the first 3 and the second 4 upper module may be a massive module or a hollow-core module with hollow channels extending in longitudinal or transversal direction of the floor element or at any angle with respect to the longitudinal direction of the floor element.
  • the first 3 and second 4 upper module may further comprise reinforcement means, which lead to a floor element with a higher load-bearing capacity.
  • third conduit elements may be incorporated into the first and/or second upper module, whereby the third conduit elements may be the same or different from the first and/or second conduit elements.
  • One or more module slots 27 can be applied in the first 3 and/or in the second 4 upper modules. These module slots 27 can be provided during manufacturing of the module or after manufacturing of the module, in the factory or on situ. These module slots 27 can be in connection with the at least one slot 23 between the first 3 and second 4 upper module. The position, orientation, width and depth of the module slots 27 can be adjusted as considered suitable by the person skilled in the art.
  • the floor element built-up with a bottom plate 2 and a first 3 and second 4 upper module may comprise only one slot 23, provided between two upright sides of the adjacent upper modules 3,4, or two or more ducts 23, 31.
  • the first 3 and second 4 upper module are positioned with respect to each other in such a way that a space is left between the first upright transversal side 15 of the first upper module 3 and the second upright transversal side 22 of the second upper module 4, which space forms a first duct 23 of the floor element.
  • the floor element may comprise one or more additional slots 31 obtained by positioning the first and second upper module in such a way on the bottom plate that a space is left between the upright edges 7, 8, 9, 10 of the bottom plate and one or more of the upright edges 13, 14, 15, 16, 19, 20, 21, 22 of at least one of the first and second upper module 3, 4.
  • a space is left between the first longitudinal upright edge 14 of the first upper module 3 and the second longitudinal upright side 8 of the bottom plate 2, which space forms a slot 31.
  • the different slots may have the same or varying dimensions and/or orientation.
  • the first upper layer may comprise only two substantially plate-shaped upper modules, but may comprise more than two upper modules placed on top of the bottom plate and connected thereto as is shown in figure 1 .
  • the different upper modules By positioning the different upper modules with respect to each other, one or more slots 23, 31 can be provided between them. Again, the different slots 23, 31 may have varying dimensions and/or orientation.
  • the top plate surface 5 of the bottom plate 2 and the bottom module surface 12, 18 of the first 3 and/or second 4 upper module preferably comprise cooperating positioning means 24, 25 with a complementary shape as is shown in figure 2 .
  • These positioning means 24, 25 can for instance comprise a cooperating rib and groove, a protrusion and recess, a tongue and groove or any other means considered suitable by the person skilled in the art, or a combination of two or more thereof.
  • the shape of the positioning means 24, 25 can be round, line-shaped, rectangular, concave, convex or any other shape considered suitable by the person skilled in the art, or a combination of two or more thereof.
  • the top plate surface 5 of the bottom plate 2 can for instance be provided with a rectangular groove which cooperates with a corresponding cooperating rectangular rib, with the same dimensions as the groove and provided on the bottom module surface of for instance the first upper module.
  • Cooperating positioning means assure a larger contact surface between the first/second module 3, 4 and the bottom plate 2. These positioning means 24, 25 also simplify the application and fixation of the position of the first 3 and second 4 upper modules on the bottom plate 2.
  • One or more additional layers may be applied on top of the first upper layer. Every additional upper layer comprises one or more substantially plate-shaped upper modules which are applied on top of the underlying layer and which are preferably connected to an upper module surface of an underlying module.
  • the different upper layers can fulfill different functionalities.

  • the upper modules which are positioned on top of the first upper layer may be the same or differ from the first upper module. They can be made of the same or different material, but are preferably made of a different material such that every layer fulfills a different functionality. Some layers may or may not comprise slots or module slots, may or may not incorporate conduit elements,...
  • a finishing plate 26 can be applied on top of the top upper layer, as is shown in figure 1 .
  • This finishing plate 26 can be made of any material considered suitable by the person skilled in the art.
  • the finishing plate 26 forms a finishing layer of the floor element.
  • the different layers of the floor element can have a different finishing level, depending on the functionality of the floor element and on the fact if these layers will be visible or not after construction of the floor.
  • the bottom plate surface preferably has a higher finishing level, such that it can function as the ceiling of the room beneath. In a garage for instance, the finishing level is less important and the bottom plate surface of the bottom plate can be rougher.
  • the floor element can be manufactured in several ways.
  • the bottom plate 2 and the first 3 and the second 4 upper module are preferably made as separate modules which are then put together on site or in the factory.

  • the size, orientation and position of the slots 23, 31 can be varied by applying the first 3 and the second 4 upper module accordingly on the bottom plate and connecting them to the bottom plate 2.
  • the modular build-up allows postponing the application of slots to a later stage in the building process, without having to cut in the floor element or remove an amount of material from the floor element. Another advantage of the modular build-up is that it is not necessary to have a different mould for every change in dimensions of the slot.
  • Slots 23 of a different width are for instance obtained by positioning the first 3 and second 4 upper module closer or more remotely from each other.

  • the type of connection determines the amount of transfer.
  • the connection is preferably such that a maximum transfer of forces can be provided.
  • An optimal transfer of forces can for instance be obtained by connecting the at least first 3 and second 4 upper modules with the aid of an adhesive to the bottom plate, wherein the floor parts may or may not be provided with positioning means, but are preferably provided with positioning means 24, 25.
  • At least one of the at least first 3 and second 4 upper module can be connected with glue, cement or concrete to the bottom plate or with any other adhesive considered suitable by the person skilled in the art.
  • the adhesive can be applied on the entire upper plate surface of the bottom plate and/or on the entire bottom module surface of at least one of the at least first and second upper module or on only part thereof.
  • the adhesive allows connecting the different floor parts to form one structural unit and thus allows an optimal transfer of forces of the at least one of the at least first and second upper module to the bottom plate and vice versa.
  • Another possibility is to mechanically connect the at least first 3 and second 4 upper module with the bottom plate 2.
  • the mechanical connection can for instance be done with screws, hooks, clamps, or any other mechanical connection means considered suitable by the person skilled in the art.
  • the first and the second upper module can be connected to the bottom plate by cooperating positioning means, an adhesive, mechanical connecting means or any other means considered suitable by the person skilled in the art, or any combination thereof.
  • Positioning means 24, 25 can be used to position consecutive layers on top of each other, for instance a second upper layer on top of a first upper layer.
  • the connection can be done in the same way as the connection between the bottom layer and the first upper layer or any combination thereof.
  • a floor By positioning at least one floor element according to the present invention with its mounting edges on supporting construction parts, such as walls and beams, a floor can be built up.
  • the different floor elements are usually positioned with their upright longitudinal sides against each other and are or are not connected to each other.
  • the upright longitudinal sides of the floor element can be flat, but are preferably provided with positioning means which are provided to cooperate with corresponding positioning means with a complementary shape on an adjacent upright side of the adjacent floor element.
  • These positioning means can comprise a cooperating tongue and groove or a protrusion and recess or any other type of positioning means considered suitable by the person skilled in the art or a combination of two or more thereof.
