Description
- This invention relates to formwork panels designed, in particular, to be used in the concrete construction industry.
- In the construction industry wooden panels have traditionally been used to build walls and floors. Said panels have a considerable thickness and weight, so said panels have evolved to get lighter boards, such as sandwich-type panels. In sandwich panels a core with a considerable thickness and made of a material that is not very strong is inserted between two stiff sheets that are thinner.
- Formwork panels of a composite material having the stiffening means built into them are also known.
-
ES2198391 T3 EP1118735 A1 ) thus discloses a monoblock formwork panel of a composite material that presents two flat parallel faces joined and stiffened by connecting crossbeams. - It is an object of the invention to provide a formwork panel, as described in the claims.
- The formwork panel of the invention comprises two parallel flat faces suitable for defining a formwork face that is in contact with the concrete. It also comprises a gap inner space defined between the two flat faces and stiffening means necessary for the formwork panel to withstand the operating pressure during the concrete setting process.
- The formwork panel of the invention also comprises two faced semi-panels coupled to each other and defining the gap inner space. Each semi-panel comprises one of said flat faces and the stiffening means are built into at least one of said semi-panels.
- Thanks to the formwork panel of the invention, the weight of the formwork panel is reduced and its rigidity increased, thereby contributing to a simpler and cheaper manufacturing process.
- These and other advantages and characteristics of the invention will be made evident in the light of the drawings and the detailed description thereof.

FIG. 2 shows a partial view in perspective of a semi-panel of the formwork panel ofFig. 1 . -
FIG. 3 shows an exploded view of the formwork panel ofFig. 1 with the corner reinforcements. -
FIG. 4 shows a cross section along the lV-lV line of the formwork panel ofFig. 1 with the corner reinforcements. - The formwork panel of the invention, as shown in
Figure 1 , comprises two parallelflat faces 3 suitable for defining a formwork face that is in contact with the concrete. It also comprises a gapinner space 4 defined between the twoflat faces 3 and stiffening means 2 necessary for theformwork panel 1 to withstand the operating pressure during the concrete setting process. - As shown in
Figure 3 , theformwork panel 1 of the invention also comprises two facedsemi-panels 5 coupled to each other and defining the gapinner space 4, as shown inFigure 4 .Figure 2 shows one of the twosemi-panels 5. Eachsemi-panel 5 comprises one of saidflat faces 3 and thestiffening means 2 are built into at least one of saidsemi-panels 5. - The
formwork panel 1 of the invention is suitable for operating at a site in conjunction with a plurality offormwork panels 1 that are joined to each other with fixing means not shown in the figures. On each use, the formwork face that is in contact with the concrete may be one of the twoflat faces 3. In this way the lifecycle of the panel is doubled, as on each use the formwork face is either oneflat face 3 or the other. In addition, the surface finish of the concrete formwork that is achieved with theformwork panel 1 of the invention is very good, with subsequent touch-up work being unnecessary. - In the preferred embodiment of the invention, the
formwork panel 1 is made of plastic, preferably a composite, such as thermoplastic or thermostable plastic, which makes the removal of theformwork panel 1 far easier once the concrete has set. In addition, theflat faces 3 offormwork panel 1 are, as their name suggests, substantially flat, which is also especially advantageous in the removal of the formwork as the concrete does not adhere to the formwork face and is easy to clean. As a result, in theformwork panel 1 of the invention, therefore, it is not necessary to use formwork-removal products, such as oils, and due to the fact that thepanel 1 may be recycled it also helps to protect the environment. - Thanks to the
formwork panel 1 of the invention, as it is made of a light material (plastic) and as it comprises the gap inner space 4 (a lightened panel with an air chamber) reinforced by thestiffening means 2, the total weight of thepanel 1 is reduced considerably without this affecting the rigidity of the panel, thereby achieving apanel 1 that is both strong and light, which is especially advantageous when handling the panels, thereby improving work ergonomics and preventing back and neck injuries or strains etc. due to improper handling. - In the preferred embodiment, as shown in
Figure 2 , thestiffening means 2 compriseribs 6 that are substantially perpendicular to theflat faces 3, where preferably saidribs 6 are disposed longitudinally. The stiffening means 2 also comprisechannels 7 in which theribs 6 of the facedsemi-panel 5 are housed. - In said preferred embodiment, the
formwork panel 1, as shown inFigure 2 , also comprisesadditional ribs 8 disposed transversally, although they may be dispensed with. - In the preferred embodiment, the two
semi-panels 5 are substantially equal. As a result, the manufacturing costs are reduced considerably as the manufacturing moulds are unified and simplified. It is not necessary to have two different moulds to obtain eachsemi-panel 5 and as theformwork panel 1 is manufactured from two semi-panels, the design of the mould is simpler and cheaper. As the moulds are easier to manufacture, breakdowns are also reduced, contributing to the reduction of costs. - Furthermore, in a simple and cheap manner, using the same mould and using different materials it is possible to obtain formwork panels with different mechanical properties, thereby complying with the different needs of customers.
- In a second embodiment not shown in the figures, the
channels 7 are in one of thesemi-panels 5, while theribs 6 are in thefaced semi-panel 5. This embodiment is a variant of the stiffening means 2 where the twosemi-panels 5 do not have to be equal. Other configurations are also feasible. - In the preferred embodiment, the
ribs 6 comprise evacuation means 9, preferably in the form of an indent, as shown inFigure 2 , to enable the removal of water that may be contained in theformwork panel 1. The water may filter through to the inside ofpanel 1 as a result of small perforations being made in the panel during construction work, such as the hammering of a nail to fix a sign, or scaffolding, so that this embodiment is especially advantageous. - The two
semi-panels 5 are faced and joined to each other by joining means such as sticking and/or screwing means. In the preferred embodiment, however, welding means are used. As a result, theribs 6 that are housed in thechannels 7 of thefaced semi-panel 5 are fixed by means of welding lines, thereby achieving a continuous and strong join. - Each semi-panel 5, in the preferred embodiment, comprises an outline on the outer edge with the result that when the two
semi-panels 5 face each other the outer edges of each semi-panel 5 are attached to each other to form a connection joint that is sealed preferably by means of at least one welding line. Said outline of the outer edge of each semi-panel 5 comprisesside walls 11 substantially perpendicular to theflat face 3. As a result, a sealed, hermetic and strong formwork panel is obtained. - A formwork panel, as it is well known by the skilled person, is subjected to severe conditions simply by being handled, particularly during the removal of the formwork, a process in which the formwork panel is subjected to various blows. The most vulnerable areas of the formwork panel must therefore be capable of withstanding said blows or impacts. Said vulnerable areas are generally the external areas, such as the outer edge, the main flat faces and the corners. When a panel is dropped it mainly occurs on the corners, which may cause a breakage or a crack that extends right through the formwork panel.
- In the preferred embodiment of the invention, the vulnerable areas of the outer edge and the
flat faces 3 are reinforced by welding lines, as described above. In order to protect the corners from impacts, theformwork panel 1 of the invention comprisescorner reinforcements 10 located in each corner of thepanel 1. - Said
corner reinforcements 10 may be made of the same material as thesemi-panels 5, but in the preferred embodiment, thesecorner reinforcements 10 are made of a stronger material to enable them to absorb the impacts better. Similarly, in the preferred embodiment saidcorner reinforcements 10 are additional components that are inserted during the joining operation of the twosemi-panels 5. To achieve this, both the semi-panel 5 and thecorner reinforcement 10 comprise guides to house thecorner reinforcement 10 in thesemi-panel 5 and thereby enable its insertion. - In a third embodiment, said
corner reinforcements 10 form an integral part of eachsemi-panel 5, a semi-panel 5 with the reinforced corners being capable of being obtained directly from the mould. Furthermore, as it is well known by the skilled person, the technology now available enables products made of different materials to be obtained in a single moulding operation, so that thecorner reinforcement 10 may be made of a different material to the semi-panel 5. In this embodiment manufacturing operations are therefore reduced as it is not necessary to insert thecorner reinforcement 10. Furthermore, saidcorner reinforcements 10 may comprise the entire outer edge in order to get a stronger edge.
