Description

[0001] Formwork Panel and Formwork System [

The present invention relates to a formwork panel which is particularly useful as a transition panel between a wall panel and a slab panel and to a docking system comprising such a docking panel.

In architectural engineering, form panels are used to set up spaces filled with reinforced bars and concrete to create walls and plates of buildings.

DE 10 2010 013 960 A1 relates to a docking system having edge panels provided on one side for walls and flat panels and on another side for the transition between walls and flat panels. The edge panel may have an indentation that allows the wall panel associated therewith to be pivoted away from the newly molded concrete wall against the fastening point between the wall panel and the edge panel.

It is an object of the present invention to provide a dice panel which enables safe and reliable handling of the panel which is part of the dice system, in particular during stripping, i.e. during disassembly of the dice system.

This object is achieved by the form panel means as claimed in claim 1.

Accordingly, the form panel according to the present invention has a top part with a certain thickness. A recess is present adjacent the top and reduces the thickness adjacent the top. Finally, a projection is projected into the indentation.

It is noted that the new type of dice panel is commonly used as a wall panel, i.e. it is oriented vertically in use. The top portion is such a portion of the panel that indicates the highest point of the panel when the panel is arranged vertically. In this orientation, the thickness extends horizontally. As will be described in greater detail below, the top portion establishes a preferably substantially horizontal surface that is part of a horizontal plane through which concrete is poured to make the plate or ceiling. Because this new panel can be advantageously used as the topmost wall panel and thus contributes to the transition to (horizontally oriented) flat panel panels, the top of the new panel is at its edges, It can be said that the reputation is set in the transition to.

The indent adjacent to the top, which reduces the thickness adjacent the top, enables the panel to be pivoted away from the (newly molded) concrete wall to remove the panel. The pivoting motion is substantially effected with respect to the transition position between the upper end and the indentation having a specific thickness. Finally, the protrusions project into the indentation, allowing the new panel to be connected to and secured with adjacent flat panel panels. Due to the indent, the pivoting movement for removing the panel can be carried out in a safe manner by an operator with no excessive force or torque and also with a particularly poor quality.

Preferred embodiments of the form panels described herein are defined in the dependent claims.

While the new dice panel may be a corner panel, the panel is substantially plate-like, and as a result, when the panel is used as a top-end wall panel, a specific feature that provides the advantages It is desirable to construct a vibrating wall panel.

In order to contribute to the safe and easy handling of the panels described herein, it is presently preferred to be made at least predominantly of aluminum. This applies in particular to the structural parts, that is, the areas that provide rigidity and stiffness to the panel. Note that these areas of the panel, which set the surface of the wall to be substantially plate-like and concrete, can be made of wood such as plywood.

In a preferred embodiment, the form panel has an inclined bottom opposite the top portion to facilitate removal of any form panels below the form panel described herein.

The pivoting movement for peeling the panel described herein is more easily performed by rounded corners which preferably reside at the top opposite to the indentation. During this pivoting motion, the edge of the upper end opposite the indentation slides along the newly molded concrete wall, and this movement is significantly smoother by the round corner.

With respect to the indentations and / or the protrusions and / or round corners, they are easily produced by extrusion molding. In particular, an integrated profile with all the aforementioned structural contours may be provided, and the uppermost region of the panel described herein may be formed.

As noted above, the present design is also based on a die system having at least one die in one of the aforementioned embodiments. Additionally, the molding system described herein includes at least one clip having a clip recess configured to receive the projection. In other words, a clip can be used to connect the panel to an adjacent panel, usually a flat panel, and the projection of the panel is preferably used to apply the necessary clamping force by the clip.

In this connection, an L-shape is preferred for the clip in order to be able to take the clip and rotate it in particular to the position where the clamping force is applied. It is noted that the indentation is preferably located in one leg of the L-shape, and the remaining legs provide a lever arm for applying the rotational force.

It has proved desirable to form at least two radial extentions in the clip to set the clip indentation since the clamping force requires a contour to offset the resistive force.

Furthermore, it is desirable to form at least one radial extension in the clip configured to act as a space between connected dice panels. The form panels may be connected at an angle of, for example, 90 degrees, and one form panel may be the form panel, and the connected panel may be a flat panel. As can be seen in the accompanying drawings, suitable angles and / or spatializations are determined by at least one radial extension, which sets the distance between the appropriate contours of the panels and, consequently, the distance of the panels themselves and / When the clip has a part, it can preferably be secured reliably.

In a preferred embodiment of the form panel with the inclined bottom, it is preferred that the formwork system comprises at least one form panel with a beveled top. The sloped surfaces are preferably complementary to each other and enable reliable stacking to set one side or wall to be formed by the concrete. In addition, as noted above, the tilted structures preferentially enable easy stripping, particularly with bottom wall panels. In other words, the new diespan and any flat panel panels supporting the efficient combination of the dies system in the upper layer in the newly formed layer are finally removed. This is because the lower wall panel can be removed first and then immediately to the upper layer.

To enable one and the same system to be provided for walls with different heights, the formwork system preferably has at least two differently sized wall form panels. In this regard, it should be noted that the new dice panel may have a height corresponding to a normal wall height. However, the new dice panel may have a significantly lower height, and other wall heights may be provided by one or more dice panels having appropriate heights. In particular, in order to ensure easy and reliable handling of the wall form panels, the form panels form the upper end and three or four different form panels form the lower part of the wall so that different wall heights can be realized, Three or four panels may be provided to form a substantial portion of the wall.

Finally, in order to accommodate the higher concrete pressures and corresponding forces present in the lower parts of the wall, in particular in the lower parts of the wall, panels with a small height may be provided, It may preferably have anchors arranged with smaller pitches. Note that the anchors preferably used with the formwork system described herein have an outer sleeve that remains on the concrete wall after they are removed.

As described above, the form panels and formwork systems of the present invention enable safe and reliable handling, particularly during disassembly of the formwork system that is stripping, for example, pivoting movements to remove the panel There is an effect that it can be carried out in a safe manner even by an operator who does not have an excessive force or torque and particularly a lack of high qualities.

Hereinafter, the present invention will be described with reference to the preferred embodiments disclosed in the following drawings:
Figure 1 shows the components of the formwork system in use;
Figure 2a shows the transition between the flat panel and the wall panel during removal of the wall panel;
Figure 2b shows the connection between the flat panel and the wall panel of Figure 2a;
Figure 3 shows the clip used to connect the panels of the formwork system.

As can be seen in FIG. 1, three or several wall form panels, including the topmost form panel 10, are used to establish a substantially vertical space in which the concrete is poured to form the wall 28. In addition, three or four flat panel panels (30) are arranged substantially horizontally to allow concrete to form the flat panel (32). The flat panel panels 30 are supported by suitable stripping heads 40 and props 42.

When the concrete of the wall 28 and the flat plate 32 is sufficiently hardened, the wall panels can be removed. This is preferably accomplished by a new dice panel 10 with a sloping bottom 18 and a dice panel with a corresponding sloped top beneath the new dice panel. These structures are first removed by turning the form panel underneath the new form panel 10 away from the wall 28 against the bottom of the panel and then removed from the other form panels < RTI ID = 0.0 > To be removed.

As can be seen in particular in Fig. 2a, the construction of the top of the new dice panels 10 makes this removal considerably easier. This is because the upper end 12 of the form panel 10 has a thickness T that sets the contribution of the new form panel to the face on which the concrete is poured to form the flat plate 32. In order to allow the form panel 10 to be removed without excessive force, an indentation 14 for reducing the thickness adjacent to the upper end is formed below the upper end. This is preferably done with rounded corner 20 opposite to the indent 14 so that the form panel 10 is pivotally rotated or tilted relative to the transition to the flat plate 30, Allowing it to fall from the wall 28 at the lower portion of the dice panel 10. In this inclined state, the panel 10 can be removed by pulling it substantially vertically downward. The point at which the depression starts below the "full" thickness T of the upper end portion 12 is preferably the same height as the lower end of the rounded corner 20 2a, or may have a height somewhat higher than the end. 1, protrusions 16 protruding into the indentation substantially perpendicular to the thickness direction (from left to right in FIGS. 1 and 2) allow the form panel 10 to be removed from the plate (30).

Fig. 3 shows this clip 22 in a perspective view. The clip 22 is substantially L-shaped and a first annular extension 26.1 extends inwardly of the clip 22 into the key hole To be inserted at a predetermined depth. A second radial extension (26.2) is configured to fasten and receive the projection (16) of the formwork panel (10). The projection 16 will be received in the clip indentation 24 between the extensions 26. Thus, in use, the (short) legs of the clip 22 having the protrusions 26 are positioned in the flat panel 30 at a position indicated by 34 and facing the wall panel 10 , Into the keyhole (from left to right in FIG. 2A). The second radial projection 26.2 is then moved in a direction substantially perpendicular to the projection 16 of the form panel 10 from the side facing the indentation 14, A pivotal rotation or a rotational force can be applied by the long leg means of the clip 22. Thus, the form panel 10 may be connected to or clamped to the flat panel 30, and the assembly of FIG. 1 may be provided.

2A, the indent 14, the protrusions 16, the rounded corners 20 and the upper end 12 are formed as an integrated profile, which is formed by extrusion molding . In addition, the L-shaped and S-shaped portions providing the reinforcing structure required for the form panel 10 can be formed as an integral profile that is part of a reliable formwork panel as described above. In particular, the integral profile can be formed of aluminum to reduce weight.

The first radial extension 26.1 includes a second radial extension 26.2 which is configured to be complementarily engaged with the indentations to establish a specific position, preferably a clamped or fastened position, of the clip 22, (Ridges: 36) facing each other.

In the illustrated embodiment, to set the relative positions of the wall panel 10 and the flat panel 30 at an angle of substantially 90 degrees, a third extension 26.3, opposite the second extension 26.2, The axial length A (along the short leg of the clip 22) is between the end of the flat panel 30 (in Figure 2 (horizontally towards the wall panel 10) and the vertical leg 38 of the S-shaped structure As shown in FIG.

This is additionally disclosed in FIG. 2B, which shows a state in which the flat panel 30 and the wall panel 10 are connected by a clip 22 means. The projection 16 of the wall panel 10 is received in the clip indentation 24 between the radial extension 26.2 and the radial extension 26.1 as can be seen only in Fig. Furthermore, in the embodiment disclosed to be substantially opposed to the extension 26.2, the radial extension 26.3 extends the distance between the flat panel 30 and the vertical leg 38, The distance of the wall panel 10 relative to the wall panel 10 is set. This, in conjunction with the fact that the top portion 12 of the wall panel 10 is adjacent to the flat panel 30, ensures a substantially 90 degree angle connection between the two panels.

Note that the clip described above with all the features and embodiments is considered a separate design that preferably enables the connection of dice panels having appropriate keyholes. Thus, the clip may have one or more of the features and embodiments mentioned and should be viewed as a description of the present specification which preferably can be combined with the dice panels and systems described herein.
