The invention relates to formwork panels for manufacture of reinforced concrete slabs · It is in particular, however Is only applicable to after an industrial Structures made of reinforced concrete using methods, which have load-bearing partitions in connection with den-Fußboderiplatten demarcate a squaring, which in turn parallel, flat, overlapping and arranged side by side Delimit cells.

A very common method of making a Cladding panel covering the top of a cell, the walls of which are already cast, consists in the use of a movable platform, the top of which is a plate contributes, the panel as a cladding surface for the too potting plate is used.

So that this platform is taking into account because of the formwork the construction tolerances are introduced and removed it is of course necessary that the lateral limits of the shuttering panel have a certain amount of play with respect to has the walls of the cell to be completed " It follows that on the edges of the panel carried by the platform with respect to the wall surface of the walls there is an interruption.

In order to have the necessary continuity between the concrete the To ensure board and that of the walls, improvised procedures are very often used on the construction site, for example, with different Materials, including plaster of paris, to make a plug or a filling «

There are, however, two elaborate processes known namely the following:

1.) The lower part of the board includes a slide rail, in which a profile part (angle) is guided parallel to the wall, which after movement, the movable plate shape in the position that corresponds to the casting of the plate. speaks, until it comes into contact with the wall, the upper part of this angle being at a certain level below the smooth surface of the plate of the Formwork panel is located. The created in this way. A gap is then filled with plaster of paris, which is then _

is smoothed to ensure a horizontal continuous surface for the formwork.

At the moment of encasing the panel is to, substituted down, so that the angle and the gypsum from the concrete surface of the panel _e are removed The angle superior gypsum is subsequently destroyed, and the angle is finally reinserted to the Bücklaufbewegung the movable platform to enable. It seems that the plaster cast above the angle will not {(

completely separates from the concrete surface with which the plaster of paris has mixed more or less, and this means that it is necessary to rework the Area corresponding to the lower part of the plate, this reworking is all the more delicate as you can see in an angle of the cell at the point of contact with the wall

surface of the wall and the lower part of the plate. On the other hand, since the contact between the vertical If the angle and the partition wall are not tight, seepage or plaster burrs will result the partition wall, which also requires post-processing and finishing work »

2 _O ) The panel is also provided with an angle running parallel to the V / and, but this angle is not laterally movable with respect to the body of the panel, and the empty space between the perpendicular angle flange and the wall surface of the wall is created by a Plastic binder filled up, which is leveled at the level of the top part of the bracket. Here, too, the area between the edge of the cladding panel and the wall surface above the angle and the plastic binder seal is filled ^{with smoothed plaster =.} When stripping the formwork there are of course difficulties similar to those mentioned in relation to the first device «

The formwork panel according to the invention comprises, like the above-mentioned panel (1), at least one guide track in which is guided by a slider that carries a profile part that adjoins the edge of the board and is parallel to the wall runs, and this panel is particularly noteworthy,

as the profile part one vertical and one horizontal th flange, these flanges having a vertical rod of compressible material adjacent to the Wall or are provided with a flat strip, whose width is less than that of the horizontal flange, which is seamless with respect to the rod adjoins, the rod and the strip being flush with the plane of the upper surface of the panel.

When the panel carried by the movable platform is brought into place for shuttering, the sliding elements forming a unit with the profile part are pushed as far as possible into the guideways so that the free edge of the flat strip abuts the corresponding edge of the panel, whereby sufficient play is formed for the platform to be displaced. The sliders are then removed until the compressible rod attached to the profile part is compressed into sealing contact with the wall, after which a filling material, for example plaster of paris, is poured into the cut created between the free edge of the strip and the edge of the panel. This gypsum is readily adjusted by means of a on the strip and the plate supported ruler and smoothed, a well-balanced Versohalungsober- is obtained fläöhe whereby at the location of the joint, which allows a satisfactory comparison \ pour.

thanks to the means provided for this purpose on the guide track-slide piece unit, the slide pieces are then reinserted into their guide tracks, after which the board is lowered and the platform removed "

3The arrangement according to the invention therefore eliminates thanks of the discharge rod every danger of shedding vcaa. Kallanilch or concrete. Along the wall ! critical area below the plate = »the dem in contact with the plaster of paris corresponds., in relation to the area, whereby a possibly Jiacharbeit is made considerably easier also shows that this rework, if it is sometimes necessary, is much less extensive than with the conventional means.

In Fig. 1, one of the two vertical walls A is shown, which form the load-bearing partition walls of a building cell made of reinforced concrete, the upper part of which is to be closed off by means of a base plate B (Figs. 2 and 3). The shuttering panel used for this purpose comprises a horizontal sheet or panel 1, which is parallel to the M

Walls A is stiffened by the box elements 2, which in turn are supported by beams 3 which are part of a movable platform, not shown.

The outermost flange 11, which adjoins the wall A, is fastened by means of screws 14 to a sealing rod 16 made of compressible material, for example vinyl chloride. The upper edge is flush with the plane of the upper surface of the panel 1, a flat and narrow stiff strip 18 is attached to the horizontal flange 17 of the profile part 13 , the upper part of which also coincides with the plane of the upper surface of the panel 1.

The sealing rod 16 can be shown in Fig. 1 and 2, compressed position are held in close contact with the wall surface a of wall A by the sliders 6 in their outermost disengaged.
