Abstract

The invention relates to a lattice structure for forming the reinforcing structure of a reinforced concrete floor, as well as a group of two or more adjacent lattice structures, a floor comprising such lattice structures or such groups of two or more adjacent lattice structures, a method of producing such a lattice structure and a method for producing a floor comprising such lattice structures or groups of two or more lattice structures.

Description

Lattice structure for forming the reinforcing structure of a reinforced concrete floor
Field of the invention 5
The invention relates to a lattice structure for forming the reinforcing structure of a reinforced concrete floor, as well as an group of two or more adjacent lattice structures, a floor comprising such lattice structures or such groups of two or more adjacent lattice structures, a method of producing such a lattice structure and a method 10 for producing a floor comprising such lattice structures or groups of two or more lattice structures.
Background of the invention 15 EP 0.552.201 describes a ‘pre-fab’ reinforced concrete floor element with a lattice structure comprising a lower reinforcement net, an upper reinforcement net and weight-saving bodies arranged between these two reinforcement nets resulting in a lattice structure. Individual lattice structures are used for creating individual, concrete shell floor elements. Such concrete shell floor elements are commercially available as 20 Filigran® floors. Such a pre-fab concrete shell floor element is formed by pouring concrete into the lattice structure to embed the full width of the lower reinforcement net in concrete, creating a concrete shell. After the concrete shell has hardened, the pre-fab floor element is then transported to a construction site where it is installed. Additional concrete is then poured onto the shell to obtain the final floor element. A concrete floor 25 is finally obtained by coupling adjacent floor elements by means of coupling bars or similar means thereby obtaining optimal resistance to shear (in the art the floor is said to behave like a ‘disc’).
A disadvantage of creating concrete floors by using pre-fab concrete shell floor elements however is that the fitting of the coupling bars at the construction site takes 30 considerable time and effort, e.g. per floor thousands of coupling bars may have to be installed between adjacent floor elements. Furthermore, during transport and installation of the pre-fab element, the weight of the concrete shell itself makes handling of the floor element more difficult.
2
It is therefore an object of the invention to provide a reinforced concrete floor wherein at the construction site the time and effort required for obtaining such a floor is reduced. It is a further object of the invention to facilitate easier handling of the lattice structure of such a floor.

Summary of the invention
Hereto a lattice structure for forming the reinforcing structure of a reinforced concrete floor is provided, comprising: a lower reinforcement net, an upper 10 reinforcement net and one or more weight-saving bodies arranged between these nets, the weight-saving bodies having a total mass lower than the total volume of the weightsaving bodies multiplied by the density of concrete that is to surround the weightsaving bodies, wherein at the outer circumference of the lattice structure one of the reinforcement nets protrudes sideways with respect to the other reinforcement net.
15 Due to the sideways protrusion of one of the reinforcements net, this protruding reinforcement net can be interconnected to the reinforcement net of an adjacent lattice structure, especially due to the protruding reinforcement net overlapping the reinforcement net of the adjacent lattice structure. Thus, the use of coupling bars is no longer necessary as the individual lattice structures are connected, thus ensuring 20 effective load transfer between these lattice structures.
An embodiment relates to a structure wherein the sideways protrusion is about equal to the width of one of the weight-saving bodies. In practice, by using such a protrusion length a strong connection to an adjacent lattice structure can be obtained.
In an embodiment one or more distance holders, for instance lattice girders, are 25 arranged between the upper and lower reinforcement nets to facilitate positioning of the upper reinforcement net on the lower reinforcement net.
Another aspect of the invention concerns a group of two or more adjacent lattice structures, wherein the protruding reinforcement net of a first lattice structure overlaps a reinforcement net of a second, adjacent lattice structure. This overlap facilitates 30 proper load transfer of one reinforcement net to the other reinforcement net in the final floor.
3
Another aspect of the invention relates to a floor comprising one or more lattice structures or one or more groups of lattice structures, wherein the lattice structures are embedded in concrete.
An embodiment relates to a floor wherein the lower reinforcement net is 5 embedded in a layer of self-consolidating concrete.
In an advantageous embodiment the layer of self-consolidating concrete has a thickness of 5-10 cm, preferably 6-7 cm, such that the lower reinforcement net is fully embedded in the self-consolidating concrete layer.
Another aspect of the invention relates to a method of producing a lattice 10 structure for forming the reinforcing structure of a reinforced concrete floor, the lattice structure comprising a lower reinforcement net, an upper reinforcement net and one or more weight-saving bodies arranged between these nets, the weight-saving bodies having a total mass lower than the total volume of the weight-saving bodies multiplied by the density of concrete that is to surround the weight-saving bodies, wherein at the 15 outer circumference of the lattice structure one of the reinforcement nets protrudes sideways with respect to the other reinforcement net, comprising the steps of: - forming the lower reinforcement net, - arranging the weight-saving bodies on the lower reinforcement net, - arranging the upper reinforcement net on the weight-saving bodies, in such a 20 way that at the outer circumference of the lattice structure one of the reinforcement nets protrudes sideways with respect to the other reinforcement net.
Another aspect of the invention relates to a method of producing a floor comprising a group of two or more adjacent lattice structures, comprising the steps of: 25 - arranging formwork at the location where the final floor is to be obtained, - positioning one lattice structure on the formwork, - positioning another lattice structure on the formwork, adjacent to the one lattice structure, - wherein one of the lattice structures comprises the protruding reinforcement net, 30 - wherein the protruding reinforcement net is caused to overlap a reinforcement net of the other lattice structure, - pouring concrete into the lattice structures such that the lattice structures are embedded in the concrete.
4
An embodiment relates to a method wherein the step of pouring concrete comprises the following sub steps: first pouring self-consolidating concrete into the group of lattice structures such that only the lower reinforcement nets are embedded therein, 5 - allowing the self-consolidating concrete to harden, then pouring regular concrete into the group of lattice structures, onto the hardened layer of self-consolidating concrete, such that the upper reinforcement nets are embedded therein, and allowing the regular concrete to harden.
10 A further embodiment relates to a method, wherein the step of pouring self- consolidating concrete into the group of lattice structures is carried out on a first day and the step of pouring regular concrete into the group of lattice structures is carried out on a second day, being the subsequent day.
Thus, the self-consolidating layer of concrete is allowed sufficient time to 15 harden, but not too long as to unnecessarily increase construction time. Preferably, the self-consolidating layer is formed in the afternoon of the first day and the regular concrete layer in the morning of the second day.

Detailed description of the invention
Figure 1 shows a cross-sectional view of a first embodiment of a lattice structure 7 according to invention. The lattice structure 7 comprises a lower 5 reinforcement net 2 and an upper reinforcement net 3. Between the reinforcement nets 2, 3 weight-saving bodies 5 are arranged. The weight-saving bodies 5 can be formed by hollow balls (as shown), cubes, or similar structures, as long as the bodies’ mass is lower than the bodies’ volume multiplied with the density of the concrete that is to be poured around the weight-saving bodies 5. To facilitate positioning of the upper 10 reinforcement net 3 above the lower reinforcement net 2, and to keep the nets 2, 3 properly positioned during the pouring of the concrete, distance holders 4 are arranged between both nets 2, 3. The distance holders 4, for example embodied by lattice girders, have an inverted V-shape for this purpose. The person skilled in the art will understand that other types of distance holders 4 can also be used, such as one-legged 15 or two-legged variants. The reinforcement nets 2, 3 comprise longitudinal reinforcement bars 8 extending in the viewing direction and transversal reinforcement bars 9 extending in a direction perpendicular to the longitudinal reinforcement bars 8. The upper reinforcement net 3 has a projecting (protruding) part 10 in the left part of figure 1, i.e. in the sense that the transversal reinforcement bars 9 and longitudinal 20 reinforcement bars 8 of the upper reinforcement net 3 extend further leftward than the lower reinforcement net 2. The right side of figure 1 on the other hand shows the lower reinforcement net 3 extending further rightward than the upper reinforcement net 3.
Figure 2 shows the assembling of two individual lattice 7 structures (the two individual lattice structures 7 in assembled form leading to the assembly/group 6 of 25 lattice structures as shown in Figure 3) for forming the final floor lattice structure.
Preferably, already during the design phase of the final concrete floor, the individual lattice structures 7 are dimensioned for their specific position within that final floor lattice. I.e. in such a way that the individual lattice structures 7 can be assembled relatively quickly on the spot to form the final floor lattice structure, much like 30 assembling the individual pieces of a puzzle. This saves a large amount of work on the construction site, and therefore saves cost.
Adjacent lattice structures 7 are designed in such a way that the projecting bars 10, 11 of the reinforcement net 2, 3 of one lattice structure 7 overlap a certain length of 6 the respective reinforcement net 2, 3 of an adjacent lattice structure 7. Due to these overlapping reinforcement bars 10, 11 the use of additional coupling bars or similar coupling means (usually at the interface of adjacent floor elements) can be avoided, saving time and cost. Furthermore, it is conceivable that only one lattice structure 7 has 5 projecting reinforcement bars/rods and the adjacent lattice structure does not have any. The presence of overlap, and the amount of overlap, depends on the constructive requirements applicable to the floor at that location.
More specifically, the final concrete floor is created by means of the following steps: first the individual lattice structures 7 are each created by providing the lower 10 reinforcement net 2, arranging the weight-saving bodies 5 on the reinforcement net 2, positioning distance holders 4 on the lower net 2 and then arranging the upper reinforcement net 3 on top of the distance holders 4 to form the final lattice structure 7.
The individual lattice structures 7 are then transported to the construction site. Firstly, formwork is arranged at the location where the floor is to be constructed. The 15 formwork can for instance be made of steel or wood. The use of formwork known as ‘table formwork’ is preferred. The individual lattice structures 7 are then each laid down on the formwork at their designated positions in the final floor lattice structure, much like a puzzle.
After the final floor lattice structure is in place, self-consolidating concrete is 20 poured into the floor lattice structure, embedding the lower reinforcement nets 2 therein. However, other types of concrete are also conceivable. Preferably, this step is carried out during the afternoon. The thickness of the self-consolidating concrete layer is about 6-7 cm.
After the self-consolidating concrete has hardened, regular concrete will be 25 poured into the floor lattice structure. Preferably, this is done the next morning. In any case this step should be carried out within 24 hrs of the pouring of the self-consolidating concrete layer. After the regular concrete has hardened, the final concrete floor is obtained. The final floor thus does not require, or hardly require, the use of coupling bars or similar coupling means due to the bars of one or more reinforcement 30 nets of one lattice structure overlapping the reinforcement nets of adjacent lattice structures.
Figure 3 shows a cross-sectional view of part of the final concrete floor 15. The layer of self-consolidating concrete is denoted by reference numeral 17, the layer of 7 regular concrete by reference numeral 18. The area of overlap of the protruding reinforcement net 10, 11 of one lattice structure 7 and the reinforcement net of the adjacent lattice structure is indicated by 16. The group of the two individual lattice structures is indicated by reference numeral 6.
5 Thus, the invention has been described by reference to the embodiment discussed above. It will be recognized that this embodiment is susceptible to various modifications and alternative forms well known to those of skill in the art without departing from the spirit and scope of the invention. Accordingly, although a specific embodiment has been described, this is an example only and is not limiting upon the 10 scope of the invention.
