Description

The invention relates to a support holder for a support of a slab formwork, with a sleeve comprising the support shaft, removable from the support and only connected to this legs, the sleeve being constructed in several parts, a sleeve section comprising the support shaft at most so far that between the Edges of this sleeve section remain an intermediate space which corresponds at least to the support diameter, and a closure is provided which holds the sleeve sections together in the position enclosing the support shaft.

In known support brackets of this type according to DE-GM 80 22 729, the legs are rigidly attached to various sleeve sections which are connected to one another in an articulated manner. In practice, the column supports are first set up and then the floor props are inserted into the column holder. This known support bracket is without support and without an operator, but has the disadvantage that at least when opening and closing the two jointly connected socket sections, one of these sections moves and the leg rigidly attached to it must be released from the floor, which means that when working with this support holder results in a rather cumbersome handling.

The invention has for its object to develop a support bracket for such construction supports, which allows easy and simple erection of the supports in rough construction site operation.

This object is achieved according to the invention in that all of the legs of the support holder act on only one of the sleeve sections of the multi-part sleeve comprising the support shaft.

An advantage of the invention is that the sleeve section with the legs attached to it can be set up so that it no longer changes its position relative to the footprint when the support is set in this sleeve section and when this sleeve section is closed by the second legless sleeve section are needed. This results in a convenient and practical Handling when using the support bracket even in rough construction site operation. If the support bracket is no longer required, for example if the support is now firmly anchored at the upper end by the slab formwork, the support bracket can be dismantled in a similarly convenient manner, simply by loosening the sleeve and then the sleeve section with the legs on the side can be removed from the support.

In the simplest case, the sleeve consists of two optionally semi-cylindrical sections which can be connected in any known manner to form a sleeve which completely surrounds the support shaft. These sleeve sections can, for example, be hinged together at their one adjacent edge by a hinge, as has become known from DE-GM 80 22 729. The closure can then engage the free edges of the sections. The sleeve sections can rest loosely or under radial tension on the support circumference.

Of course, the invention is not limited to the fact that the sleeve consists of two hinged half-shells, rather the sleeve can also be divided into three or more sections.

It is also not necessary for the inner surface of the sleeve to have the shape of a cylindrical sleeve. In one embodiment of the invention, the sleeve has a rectangular inner cross section; it can have contact surfaces for the circumference of the support on its inner wall. This cross sectional shape has the advantage that, according to a further embodiment of the invention, one section of the sleeve has a U-shaped cross section and the other section can be fastened to the two ends of the legs of the U cross section and can have a particularly simple, for example flat, shape.

Finally, the invention is not limited to the fact that the individual sections of the sleeve are connected to one another in an articulated manner; rather, the sections of the sleeve can also be non-contiguous, with a tensioning band being provided which holds these sections to the support circumference.

However, both in the embodiments in which the sections of the sleeve are connected to one another in an articulated manner and in those embodiments in which the individual sections of the sleeve are not connected to one another in an articulated manner, all legs always act on only one sleeve section.

The legs can be rigidly connected to one sleeve section. In a preferred embodiment, however, the sleeve portion to which the legs are connected has spreadable legs. In embodiments of the invention, the expansion or joint axis runs parallel to the support axis. This has the advantage that this makes the construction much simpler, since in this case the cross struts supporting the legs at their socket-side end also only have to be pivoted about the same pivot axis as the spread leg.

This embodiment has the further advantage that, if necessary, for example in tight spaces, legs can be spread back if the support is to be held against falling over in only one plane, for example if it is already fixed in one direction at its upper end and can only fall over in the plane perpendicular to it. Since spread legs of a prop holder hinder walking and working in the space below the slab formwork, it is advantageous not to have to spread more legs than is absolutely necessary. Finally, it is also advantageous in this embodiment that the spread legs can be easily stacked together with their sleeve section and are easy to transport.

The advantage that no more spreading legs hinder the work under the ceiling formwork than necessary and the advantage of easy stackability can also be achieved in an embodiment of the invention in which a rigid leg and a swiveling leg are arranged on each of the sleeve sections whose pivot axes run parallel to the column axis. The pivot axes of these articulated legs can be arranged so that the latter can be folded into a position in which they rest on the rigid leg. This can be done, for example, in that the pivot axes of the movable legs lie in a plane which is perpendicular to the plane of the rigid leg, and in that the distance between the two axes corresponds to approximately twice the thickness of a leg when the pivot axes pass through the median plane of the legs run. During transport or when not in use, the three legs can be folded parallel to each other, when the support is placed against the wall, legs that are not required for support can also be folded into the rest position.

If the individual sleeve sections are connected to one another in an articulated manner, in this embodiment the articulated connection between two adjacent sleeve sections can be designed in such a way that the two sleeve sections can not only pivot about an axis parallel to the support axis, but can also shift in height with respect to one another. for example, if the two sleeve sections are only connected to one another by rings. However, since the individual sleeve sections are connected and can be placed around the support shaft in the manner of a cuff, all essential parts of the support holder are always at hand.

As a closure for a band that tensions the sleeve sections against the support shaft or, in the case of contiguously provided sleeve sections, for joining the free edges after folding over the support shaft, conventional clamp closures or quick closures, also eccentric closures or the like, can be provided.

As already mentioned, it is not always necessary for the support holder to lie against the circumference of the support under tension. A little play between the inner surface of the sleeve and the outer surface of the support is in certain applications Use cases if the sections of the sleeve are hinged together.

In one embodiment of the invention, in which the sleeve is in two parts and on the one sleeve section of which all three legs are arranged, the legless sleeve section serving to close the lateral opening of the one sleeve section can be further developed in such a way that the two sections are connected to one another, that the two edges of one section have a guide into which the other section is inserted. The longitudinal direction of the guide can run parallel to the axis of the support, which is useful in those cases in which there is still some play between the sleeve of the support holder and the circumference of the support. In another embodiment of the invention, the guide, in which the other sleeve section is guided, runs obliquely to the support axis, so that when the slide representing the other sleeve section is inserted, the slide approaches the support circumference during insertion, finally comes to rest against the support circumference and the support wedged into the sleeve. In this embodiment, the tensioning device thus formed consists in the wedge-like guidance of the one sleeve section in the other sleeve section. The guide can be formed, for example, by grooves or flanged, possibly U-shaped flanged edges of a sleeve section.

The oblique guide not only clamps the support wedge-like in the sleeve, but also has the advantage that supports with different diameters can be attached in one and the same sleeve, because the guide, which runs obliquely to the support axis, radially counteracts the sleeve section guided in it leads the column circumference.

If you want to keep the guide as short as possible, various other legless sleeve sections or counterparts can be assigned to the one sleeve section with the legs, the contact surfaces of which protrude differently into the space encompassed by the one sleeve section and are thus assigned to different shank diameters; however, the legless sleeve section can also have contact surfaces that protrude to different extents on both sides.

In a further embodiment, the two sleeve sections have a contact surface that runs parallel to the support axis. This contact surface can also be broken up into a plurality of sections spaced apart from one another, for example into two bumps spaced apart from one another.

The cross section of the sleeve section having the legs can be essentially U-shaped, the guide running obliquely or parallel to the support axis being arranged at the leg ends of the U-shaped cross section.

The fastening of the two sleeve sections to one another by means of a wedge guide, which also clamps the sleeve onto the support, also has the advantage that the support holder holds the support in the event of any height differences between the legs of the support holder, that is to say with a somewhat inclined sleeve.

In the drawing, an embodiment of the invention is shown.

• Fig.l shows a side view of the essential parts of an embodiment of the support holder according to the invention in a section along the line II of Figure 2;
• Fig. 2 shows a top view of the support bracket from above, each with legs broken off.

In the embodiment of the invention shown in the drawing, the support holder has three legs 1, 2 and 3, which are shown broken off in the drawing. The legs are slightly bent at its upper end, the leg 2 is rigidly fastened, for example welded, in a receptacle 4, which has two horizontal plates 5 and 6 running parallel to one another. The legs 1 and 3 are pivotally mounted in the receptacle 4 about vertically extending bearing axes 7 and 8 forming bolts. The legs 1 to 3 have cross struts 9 and 10, which run approximately horizontally and are rigidly connected, for example welded, at their outer end to about half the height of the legs. The cross strut 9 for the leg 2 is welded into a receptacle 11 corresponding to the receptacle 4 is at a distance of half the height of the leg below the receptacle 4. The cross strut 10, which is welded to the leg 1, and the further cross strut, not shown, which is welded to the movable leg 3, are mounted at their inner end in the receptacle 11 about the vertical axes 7, 8. The pivot axes 7 and 8 lie in a plane which is perpendicular to the plane of the rigid leg 2. The distance between these two pivot axes is approximately twice the width of one of the legs 1, 2 or 3 of the same width, so that the legs 1 and 3 can be folded into a rest position parallel to the rigid leg 1 and rest against this leg 2 in this rest position .

The receptacles 4 and 11 are attached to the yoke 12 of a sleeve section 13, the edges 14 and 15 of which are flanged at the ends of the legs and run at an angle between 5 ° and 15 ° obliquely to the plane of the yoke 12 downwards. The opening of the U-shaped cross section of the sleeve section 13 is closed by a slide 16, which on the edges of a substantially flat plate 17 on one side has parallel guides formed over the entire height of the plate by flanging the plate edges 18 and on the other side of the plate 17 guides corresponding to the guides 18, which however do not pass over the entire height of the plate, but by U-shaped flanging of the ends 21, 22, 24 and 25 of two metal strips 19 and 20 fastened to the plate 17 at a distance from one another are formed. The hooks 21 and 22 overlap with plenty of play the flanged edge 14 of a socket leg 23 bent at right angles from the socket section 13, the Hooks 24 and 25 also encompass, with ample play, the right-angled edge 15 of a sleeve leg 26 bent from the sleeve section 13. This engagement causes the slide 16 to be displaceably guided in the sleeve section 13 with the aid of an oblique guide.

The slider 16 also has two bumps 27 and 28 on one side and further bumps 29 and 30 on the opposite side of the plate 17. The bumps 27 and 28 have, at their end facing away from the plate 17, bearing surfaces 31 and 32 which lie in one plane, but which runs parallel to the plane of the yoke 12. The bumps 27 and 28 therefore project equally far into the interior of the U-shaped sleeve section 13, but since the guide in which the slider 16 is held runs obliquely to the yoke plane 12, the bump 27 is higher than the bump 28.

If the slider 16 is pulled out of its guide upwards, the sleeve section 13 can be guided from the side, that is to say radially, to a support shaft 35 until it abuts the yoke 12. If the slider 16 is then inserted into the oblique guide from above and moved downward, the contact surfaces 31 and 32 come to bear against the support shaft 35 and press the support shaft 35 against the yoke 12 and the hooks 21, 22, 24 and 25 the flanged edges 14 and 15, respectively, so that the support shaft 35 is firmly clamped between the yoke 12 and the contact surfaces 31 and 32. If the diameter of the support 35 is somewhat larger or smaller than indicated in FIG. 2 and in FIG. 1, the clamping position occurs when the slider 16 is inserted a little less or a little deeper.

If the support bracket is to be fastened to a support 36 with a substantially larger diameter, the slider 16 is inserted into the oblique guide in such a way that the protuberances 29 and 30 protrude into the interior of the U-cross section of the sleeve section 13, to the extent that they are Shelf 33 and 34 come to rest on the circumference of the support shaft 36 and wedge it between the sleeve portion 13 and the slider 16.

On the outer surface of the leg 26 of the sleeve section 13 there is a stop 37 projecting from the surface of the leg 26, against which the lower edge of the hook 25 or the lower edge of the opposite guide 18 comes to rest and the downward movement of the slide 16 limited before it slides down out of the guide.

If the support bracket is no longer needed because the ceiling support is already fixed at its upper end by the beams of the ceiling formwork, the slider 16 is pulled out of the sleeve section 13, so that this section together with the legs in the lateral direction from the fixed support 35 or 36 can be removed and used for other purposes. Of course, such a column holder can also remain on the column until the slab formwork is removed.

The contact surfaces 31 to 34 and also a contact surface on the inside of the yoke 12 have a V-shaped cross section, which forms a good support for round column cross sections.

The bumps 29 and 30 with their contact surfaces can be omitted in other embodiments. Whether these are expedient depends on how diagonally you want to form the guide formed by the parts 14, 15, 21, 22, 24, 25.
