Definitions
- the object of the invention is a concrete floor panel and the method of production of such panel.
- the object of the invention is also a floor made of these concrete panels.
- the hollow bricks can be made of ceramics, concrete and gravel, concrete and slag, concrete and rubble, lightweight concrete, foamed polystyrene, gypsum.
- Reinforced concrete beams protect the hollow bricks against damage and are an underlay for the floor.
- the structure made of beams and hollow bricks is poured with a layer of concrete topping, which covers the hollow bricks and fills the empty spaces between them and the beams.
- Filigree slabs It is a stay-in-place formwork slab comprising longitudinal and transverse supporting reinforcement and sunken trusses allowing transport of slabs. Such slabs had to be individually designed for the building dimension. In addition, if the slab had a defect, it had to be made again. Filigree slabs could not be cut on site and their size required heavy equipment both in production and on site.
- Such slabs usually include a reinforced structure on which relatively lightweight/foam blocks of the hollow block type are placed.
- floor system according to the well-known Master product on the market: http://www.konbet.com.pl/System_stropowy_MASTER,1722.html refers to a system comprising prestressed concrete beams responsible for the floor bearing capacity and dedicated floor hollow blocks, on the basis of which systems of various heights and spans can be built.
- the hollow bricks can be 3-chamber expanded clay aggregate concrete block, concrete, concrete and gravel and 5-chamber expanded clay aggregate concrete block - this hollow brick has the so-called upper shelf, this means that at 24 cm of the floor, it does not requires additional concrete topping and has additional thermal insulation parameters.
- Application DE2550324 (A1 ) discloses a floor element for roofs, ceilings and walls with a hollow frame formed by reinforced concrete longitudinal and transverse ribs as a support for part of the slab. It has a layer of plain concrete at least on the underside of the frame and a light filling between the ribs. It is therefore a two-way reinforced concrete slab with dimensions preferably approx. 2.5 x 7.5 m. To insert a light filling between the ribs, the concrete structure must be made in advance and wait until the concrete hardens. Then, take off the formwork and pour the created spaces with light material. It is a very labour and time-consuming method - it takes up to 1-2 days for the concrete to dry. In addition, it is impossible to achieve a permanent bond between lightweight material and plain concrete.
- KR 2016 0039855 A discloses a concrete floor panel according to the preamble of independent claim 1. Due to the disadvantages of solutions known in the state of the art, it is necessary to look for new floor slabs that meet the disadvantages of solutions from the state of the art. The technical problem that the present invention solves is therefore to provide a concrete panel for the production of floors, which can be made quickly, with low labour consumption, which can be prepared in almost any size on request, and at the same time ensuring easy production of a floor which will have a load-bearing capacity appropriate for floors and will also exhibit thermal and sound insulation properties. Providing such a slab requires the use of special manufacturing technology.
- the object of the invention is a concrete floor panel according to independent claim 1 consisting of a structure made of plain concrete with reinforcement sunk inside and a part of lighter material than plain concrete, characterized in that the concrete structure consists of:
- the concrete floor panel is characterized in that the prestressing elements are lines or prestressing wires.
- the concrete floor panel is characterized in that two concrete beams are placed on the slab.
- the concrete beams are placed on the slab symmetrically and parallel to each other and to the panel edges.
- the material lighter than plain concrete is lightweight concrete selected from polystyrene concrete, perlite concrete, expanded clay concrete, aerated concrete, foam concrete. Also, preferably, the material lighter than plain concrete is polystyrene concrete made of regranulate constituting shot-blasted recycled polystyrene.
- the invention also relates to a method of production the concrete floor panel according to independent claim 6, comprising the steps of:
- the subject of the invention is also a floor comprising the stacked concrete floor panels described above poured with concrete topping.
- the panel slab should preferably be relatively narrow, in the range of 30-100 cm. With larger slab widths the panel could crack.
- the spacing of the beams on the slab creates an asymmetrical spatial arrangement - when the panels are stacked, inter-beam spaces are obtained: one wider (in the case of two parallel beams - the first space), e.g. preferably 25 cm width filled with a lighter material than plain concrete and a second space with a width of e.g. 15 cm, a hollow space which is filled on the construction site with concrete topping (structural concrete).
- a supporting or other shear reinforcement it is possible to add a supporting or other shear reinforcement.
- Part of the material lighter than plain concrete can be made using recycled material.
- An example of such a material lighter than plain concrete is shot blasted polystyrene.
- a positive aspect of the invention is then the use of recycled materials, which is a desirable ecological aspect for the production of the panel according to the invention.
- separating and supporting reinforcement can be placed on the arranged panels according to the invention.
- separating and supporting reinforcement should be used in all types of floors, especially for large spans.
- the invention as described herein eliminates the disadvantages of prior art floor systems.
- the slabs and the floor themselves are characterized by low weight due to the material used to fill the space between the beams.
- the low weight of the slab makes it easy to transport and assemble.
- the low weight of the floor reduces the amount of steel used in the structure of the floor and reduces the load on walls and foundations, which allows reducing their load capacity or thickness.
- the panel according to the invention - in contrast to the state of the art solutions - has no transverse reinforcement sunk in the structure of plain concrete.
- a new method was used in the technology of producing the concrete floor panel. It is a method combining the known sliding method of making a slab of plain concrete and then beams of plain concrete. This step of work is performed with a "slipformer" type device. Then, to produce the panel according to the invention, a lighter material than plain concrete must be injected between at least two beams of plain concrete. In order to obtain a permanent connection between plain concrete and a lighter material than concrete, the injection is made during casting (panel injection in the final step) when the plain concrete of the panel is still wet and malleable. Then, plain concrete is chemically bonded to a lighter material than concrete. This step of the method is performed using a device, that precisely injects lighter material than concrete into the first spaces between the beams and at the same time levels the upper surface between the beams.
- the injection (extrusion) device consists of a screw that presses the material lighter than concrete, a throat through which the material is laid out and a strip limiting the first filling space from the top, which forms and smoothes the material.
- the extrusion device is also known and used in the production of e.g. hollow floor slabs.
- the panel is a complete, consistent product that is ready to use. Thanks to the application of the above described technology, part of the material lighter than concrete is an element of the panel and does not have to be introduced into the structure on the construction site in the form of separate lightweight blocks/hollow blocks.
- FIG. 1a and 1b A basic variant of the floor panel 1 according to the invention is shown in Figs. 1a and 1b .
- the concrete floor panel 1 consists of a structure 2 made of plain concrete containing sunken prestressing elements 4 which are prestressing strings.
- the structure 2 consists of a slab 3 of plain concrete and two beams 5 of plain concrete placed on slab 2. Two strings run in slab 2 under each beam 5, one string runs through each beam 5. Beams 5 parallel to each other define on the slab 2 one first space 6, which is filled with polystyrene concrete, which is a part of the material 7 lighter than plain concrete. Polystyrene concrete is combined with plain concrete of the first space 6 with a permanent chemical bond formed during the extrusion process.
- Ready-made panel 1 has a length of 8 m, width 60 cm, 20x20 distance between beams 5 (second space 10 x distance between beams 5).
- the distance between beams 5 can also be up to e.g. 6x34 cm, where the first dimension is the external distance (second space 10) and the second dimension is the distance between beams 5.
- Further preferred embodiments of the invention may have three, four, five and more beams 5.
- the material lighter than concrete is one of the materials listed in the claims.
- the material used does not require the use of other panel parameters.
- Fig. 2 shows the concrete floor panels 1 according to the above example, stacked as prepared for pouring over concrete topping 9 to form floor 8.
- the second space 10 is shown, created by applying two panels 1.
- Fig. 2 also shows how the separating reinforcement 11 and the support reinforcement 12 can be arranged, however, as indicated above, such reinforcement is not required for the implementation of the invention and solving the technical problem by the invention.
- Floor 8 according to the invention is explained in Fig. 3 .
- Floor 8 with concrete panels 1, described in the example above, flooded with concrete topping 9 is presented in cross-section.
- concrete floor panels 1 are stacked and poured with concrete topping 9 so that, the concrete is introduced into the second spaces 10 created by applying panels 1.
- Concrete topping 9 also covers the part of material 7 which is polystyrene concrete.
- the concrete floor panel as described in the embodiment above is made as follows.
- slab 3 was made of plain concrete with use of a "slipformer" type device.
- two beams 5 on slab 3 were produced using the same technique.
- liquid polystyrene concrete was injected between two beams 5 of plain concrete. Cycles follow one another, on a single machine, driving along the track (mould) at a speed of about 2m/min. The faster the polystyrene concrete is injected, the binding effect will be better. It is the best to do this directly after forming a slab 3 and beams 5.
- plain concrete and polystyrene concrete cures simultaneously.
- panel 1 After about 20 hours, panel 1 is ready to be cut into sections according to the customer's request and is transported to the finished goods warehouse or directly to the construction site where it will be installed.
- the second step of the method was performed using the injection (extrusion) device consists of a screw that presses the polystyrene concrete, a throat through which the polystyrene concrete is laid out and a strip limiting the first filling space 6 from the top, which forms and smoothes the material.
