BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a longitudinal support for horizontal placement such as stiffening of formwork plates, epundum planks and similar formwork elements for tomb formwork, consisting of paired formwork walls which are spaced apart by means of spacers transversely of the longitudinal axis.

In large-scale formwork, so-called edge carrier plate formulations are known. This is understood to mean formwork which, from parallel formwork walls with T- or C-shaped vertical guide heads, engages in vertical guide pieces, which themselves have a C or T profile, so that a safe guide is obtained. The guide supports and the formwork walls inserted therein are spaced apart by the horizontal play-out means held in the guide supports in the transverse length axis, and they can be pressed against the grave wall in built-in condition. In particularly deep graves, guide supports with several parallel guides are used so that the formwork walls can be placed stepwise over one another. Edge inheritance or scaling allows for alternate expansion and compression of the formwork elements.

A simpler form of the formwork walls of this kind has at its ends adjacent to the guide head - ie on the inner planar sides - fixed vertical C-profile guides or retaining rods into which either the play-out members or the guide heads can be inserted from the cross-beam axis directed formwork walls . Since these formwork walls can be fitted with square closed formwork wall chambers, these formwork walls are also referred to as shaft plates. These are at least rigidly connected in pairs by means of slots and placed in an already formed tomb.

In both formwork, then difficulties arise when the tomb is crossed by, for example, pipelines,. which is not precisely positioned at the end of a formwork wall, even when offered in different standard lengths. In such cases, the tomb formwork must be interrupted, and a temporary formwork must be built in at this place, similar to the previous common wood formwork or a frame-shed formwork. These places are not only particularly vulnerable but are also very labor intensive. Furthermore, they disrupt the entire formwork system.

Similar problems also arise when the tomb width is suddenly enlarged and when there is no short formwork walls available across the length of the tomb axis.

Therefore, the object of the present invention is to provide in these cases a longitudinal support which allows the formwork walls at such interruption or disturbance locations to be connected in a systematic manner, even when, at this point, small formwork walls may be used at this location. .

According to the invention, the solution to the posed task is that the ends of the longitudinal support in each bracket are mounted pivotally about axle bolts arranged to be arranged vertically, which bracket is connected in one piece with a clamping shoe consisting of a its longitudinal axis parallel to the axis bolt extending - the C-profile carrier, whose groove opening away from the longitudinal carrier, and that in the rib of the clamping shoe at least one perpendicular to the axis has a clamping tray whose width is greater than the C-profile drag's net width.

Such longitudinal supports replace the well-known wooden formwork of conventional chest beams, which have the advantage of being fastened with their clamping shoe to both the formwork wall guide heads and C-profile-like guides or guide supports and in this way can be connected firmly to the existing large flat formwork. Their pivotality also enables the formwork to be continued at an angle to the previous direction. They can even be pivoted at a right angle outward or inward relative to the formwork wall and serve as a stiffener for grave extensions or for a tomb finish.

Advantageously, the longitudinal carrier consists of at least two longitudinally displaceable and reciprocally held parts. In this way it is possible to adapt the length of the bridging part to the local conditions.

The invention will be explained in more detail in connection with the drawing, in which fig. 1 is a plan view of a longitudinal support connected to a formwork wall according to the invention; FIG. 2 shows a vertical section along line II-II of FIG. 1, FIG. 3 is a vertical section along line III-III of FIG.

5, FIG. 4 is a front view of FIG. 3, FIG. 5 is a plan view of FIG. 3, FIG. 6 is a plan view of a tomb formwork with a cord crossing the tomb; FIG. 7 is a plan view of a formwork finish, and FIG. 8 is a plan view of a formwork with a steeply extended grave.

FIG. 1 and 2 show the guide heads 2 designed as T-shaped strips in two flushing directions, but due to a not shown distant spacing walls 1 formed as shaft plates with the guide heads 2 located near the inside of the formwork wall. guides 3 for playback means not shown.

Each guide head 2 abuts on the inside of two flanges 4 of a profile C-shaped clamping shoe 5 and is pressed against them by means of a clamping tray 6, which is connected to clamping screws 8 which protrude the clamping pin ribs 7 in one piece with each clamping shoe 5 is connected a C- or fork-shaped bracket 9 through which is inserted an axis 10, the axis of which is parallel to the axis of the clamping shoe 5.

In each bracket 9, a head 11 is pivotally accommodated by a longitudinal carrier 12, which is at least telescopically displaceable in one head. It may also consist of several tubes which are telescopically displaceable in each other. The length of the length carrier can thus be adapted to local conditions.

Further, on the outside of the clamping shoe 5, a cover plate 13 is provided which covers the gap between the clamping shoe and the formwork wall 1.

FIG. 3-5 generally show the same arrangement, except that clamping jaws 16 which are located outside the flanges 4 of the clamping shoes 5 and by means of clamping screws 18 are pressed against the flanges 14 on a guide support 15 belonging to a rim carrier formwork. .

In order to be able to use the arrangement according to the invention for both exemplary embodiments, the clamping screws and clamping trays need only be replaced. The drawing shows embodiments in which the distance of the clamping screws 8, 18 is different according to the arrangement of the clamping jaws 6,16. However, the same screws and clamping trays can also be used.

To allow for easier adjustment of the clamping screws 8 by the arrangement shown in FIG. 1 and 2, for this purpose, as shown in FIG. 4 horizontal long holes 17 in the clamping shoe 5 ·

FIG. 6-8 show examples of application of the longitudinal wires according to the invention at various graves.

In FIG. 6 there are two escaping but axially spaced shaft formations 19, 20.

The tomb, which is not shown, is crossed by a pipeline 21 shown in broken lines.

At the ends of the shaft plate, clamping shoes 5, which are connected to each other by means of telescopically extendable and pivotable longitudinal supports 12. are fixed on the outside of the longitudinal supports 12, small formwork formwork elements, e.g. channel planks 22 with trapezoidal profile in such a way that the formwork interruptions are largely secured.

FIG. 7 shows an application of a longitudinal support 12, where it connects two opposite shaft walls 19 to each other and enables a tomb shutter to terminate the formwork. This burial pad is again formed by small surface formwork elements, e.g. duct boards 22.

FIG. 8 shows an arrangement of two axially spaced escaping formwork 19,20 and an intermediate formwork 23, the width of which is substantially greater than the width of the formwork 19 and 20.

To compensate for these width changes, at the ends of the formwork 19,20 and 23, clamping shoes 5 are provided with these connecting longitudinal supports 12 against which frame planks 22 or the like, which bridge the width difference, are supported.

Thus, the arrangement according to the invention can be used very versatile and forms a reliable connection between two formwork walls or supports, which must be spaced apart.
