Definitions
- the invention relates to a formwork system for concrete parts with a base plate on which a magnetic body can be placed, which fixes formwork or fastening parts at their respective positions.
- a formwork system of this type is known from DE-OS 43 27 696.
- Formwork systems of this type are used in production plants for prefabricated concrete components. They have the advantage that no holes or the like have to be provided on the base plate in order to be able to fasten formwork for concrete parts of different sizes on the same base plate. Instead, formwork of the desired size is put together on the base plate, which is usually made of steel, and the individual formwork elements are then connected to magnets by means of corresponding bracing or coupling elements, which are adhered to the base plate.
- the formwork parts have a lifting bracket overlapping the magnet, wherein on the side of the magnet body facing away from the base plate there is a gap between the latter and the lifting bracket into which the magnetic body can be drawn.
- the invention has the advantage that when the formwork is removed, the formwork part together with the magnetic body must be lifted off the base plate, which means a considerable simplification of the formwork, which can now be done in one operation.
- the formwork and the magnetic bodies can be brought together to a central cleaning station, where they can be cleaned for re-use, whereas previously separate transport options had to be provided for the magnetic bodies.
- the lifting bracket Due to the possibility of pulling the magnetic body into the lifting bracket, the contact between the magnetic body and the base plate can also be released in a simple manner, so that its adhesive forces no longer impede the removal of the formwork parts. It has proven to be advantageous here that the lifting bracket is designed as an integral part of the formwork. This enables a very compact design and the formwork can therefore be stacked more easily when not in use and is therefore easier to store.
- the lifting bar can be exchangeably attached to the formwork.
- this makes it easier to clean.
- a lifting handle can also be used with different formwork, which means that the costs of the formwork can be reduced. If one considers that a large part of the formwork is only kept in stock for contingency cases, a considerably lower capital tie-up can be achieved with this store.
- the magnetic body With a bore in which a lifting rod which is supported on the lifting bracket then engages.
- the magnetic body can be pulled into the lifting bracket in a manner that is reliable in operation by means of this lifting rod.
- the lifting rod can have a thread, for example, so that the magnetic body is raised by its rotation. You can use this thread both Combine with a threaded hole on the lifting bracket as well as with a threaded hole on the magnetic body.
- the tool in the form of a wrench required to turn the lifting rod is usually available on all construction sites.
- the lifting rod can also be supported on the lifting bracket with the interposition of a spring, which then has in particular a spring force that is less than the adhesive force of the magnetic body placed on the base plate.
- the magnetic body is lifted at least on one side by a slight lifting of the magnetic body, the then remaining force of attraction of the magnetic body to the base plate being considerably lower than the adhesive force of the magnetic body lying flat on the base plate. This means that the magnetic body can be lifted further from the base plate and pulled into the lifting bracket automatically via the spring.
- the spring can be, for example, a helical spring or a stack of plate springs.
- the conditions under which the device according to the invention is used are extremely wear-and-tear.
- the individual parts can often come into contact with liquid concrete which easily attaches to them, so that the parts are subjected to high abrasive stresses when rubbed against one another.
- the bore for the lifting rod on the magnet body is provided with a thread which is located on an exchangeable section of the magnet body. This ensures that it can be easily replaced if it is dirty, worn, or no longer usable for any other reason.
- the lifting rods will advantageously engage the ends of the magnet body, since this enables particularly favorable lever and force relationships to be achieved.
- the threaded, exchangeable section is also arranged at the end of the magnet body, which makes it easier to disassemble and replace.
- the exchangeable section is arranged within a circumferential surface of the magnet body which is open in a U-shape towards the base plate and from which it can be pulled out laterally for replacement.
- the legs of the lateral surface at least locally decrease in their clear distance from one another, prevents the interchangeable section from accidentally falling out of the magnet body.
- the interchangeable section is also made of a material that is attracted to the magnet located in the magnetic body, it is also prevented from falling out laterally.
- the forces acting on the interchangeable section from the magnet can be so great that a joint is provided between the interchangeable section and the magnet adjoining it in the magnet body for the attachment of a separating tool.
- the separating tool e.g. B. a screwdriver
- the replaceable section is then levered off by the magnet.
- the mentioned hole through the magnetic body or through the exchangeable section advantageously is a through hole so that no dirt accumulates in it but falls through this hole.
- the magnetic body is lifted at only one end, it is advantageous if the magnetic body has a rolling edge at the other end, with which it still rests on the base plate when it is lifted on one side, in order to prevent that a point loading of the base plate with high Hertzian pressure occurs at this support point.
- this configuration also ensures that the one-sided lifting of the magnetic body removes the adhesive force between the magnetic body and the base plate and between them only the lower force of attraction still acts, so that the springs are then able to automatically lift the magnet body from the base plate.
- FIG. 1 longitudinal section through a formwork system according to the invention
- FIG. 2 shows a section through a formwork system according to the invention along line II-II in FIG. 1.
- FIG. 3 shows a section through a formwork system with a spring-supported lifting rod and a lifting bracket which is exchangeably attached to the formwork;
- FIG. 4 side view through the formwork system according to the invention according to FIG. 3;
- FIG. 5 different phases of lifting a magnetic body on spring-supported lifting rods.
- FIGS. 1 and 2 A formwork system according to the invention is shown in FIGS. 1 and 2 with lifting rods which are provided with a thread.
- a magnet 2 is placed on a base plate 1, which is made of steel and is therefore magnetic, and is fixed and immovable sets its magnetic adhesive forces on the base plate 1.
- the magnet 2 is part of a magnet body 2A, in which the magnet 2 is surrounded by a U-shaped jacket surface 3 which is open towards the base plate. This outer surface 3 protrudes at the ends 4, 5 of the magnetic body beyond the inner magnet 2.
- the jacket surface is provided with perforated holes 6, 7. Below these holes 6, 7 there are replaceable sections 8, 9, which also have holes, but which, in contrast to the holes 6, 7, are provided with threads 10, 11.
- Threaded lifting rods 12, 13 run through the perforated holes 6, 7 and the threaded holes 10, 11 of the exchangeable sections 8, 9. These lifting rods are supported on a lifting bracket 14 which is an integral part of a formwork 14A.
- a number of magnetic bodies 2A are placed on the base plate 1 via their magnets 2.
- the formwork 14A is then placed over the magnet body 2A which determines the dimensions of the precast concrete parts, with webs 15, 16 located at the bottom of the formwork 14A sliding laterally past the lateral surface 3 of the magnetic body 2A and thus the position of the formwork 14A on set the magnet body 2A.
- the lifting rods 12, 13 are inserted through the formwork 14A or the lifting bracket 14 integrated into them, which in the example shown here are designed as screws with a hexagon head 17, 18.
- the lifting rods 12, 13 are screwed at their lower ends into the thread 10, 11 of the interchangeable sections 8, 9 which are to be attributed to the magnetic body 2A.
- the formwork 14A is pulled against the base plate 1.
- a torque wrench attached to the hexagon head ensures that the tensile force exerted on the magnets 2 by the lifting rods 12, 13 does not become higher than the lifting force for the magnet 2.
- the precast concrete part is then poured.
- the formwork 14A must be detached from the base plate 1 again.
- one of the lifting rods for example the lifting rod 13 is tightened beyond the torque mentioned above, whereupon the end 5 of the magnetic body 2A lifts off the base plate 1 and is pulled into a gap 19 which is between the base plate 1 opposite side of the magnetic body 2A and the lifting bracket 14 is formed.
- the magnetic body 2A pivots at the opposite end 4 about a rolling edge 20, which then forms a line contact between the magnetic body 2A and the base plate 1.
- the magnetic body 2A no longer has adhesive contact with the base plate 1 over its entire surface, only the magnetic attraction force acts between it and the base plate 1, which is considerable lower than the previous adhesive force.
- the magnetic body 2A can now be easily completely detached from the base plate 1 by lifting the end 4 which has not yet been raised.
- the formwork 14A can then be easily removed from the finished concrete part (to the left in FIG. 2).
- the lifting rods 12, 13 are then unscrewed again from the threads 10, 11 of the exchangeable sections 8, 9 and the magnetic bodies 2A can then be used again. However, they are usually cleaned beforehand.
- a magnetic body 2A as shown here can then be used further, however, in that only the interchangeable section 8, 9 is removed and replaced by a new one which has a new, unclosed thread.
- the interchangeable sections 8, 9 consist (in particular also for cost reasons) of simple steel which is attracted by the magnet 2, with which the interchangeable sections 8, 9 are also fixed in this direction.
- such a magnetic body 2A can also be used on a base plate 1 without the formwork 14 described above. Then a known bracing or coupling element is connected to the magnetic body 2A via one of the bores 8, 9 provided with threads 10, 11.
- a lifting rod 13 running through the thread 11 would be screwed in until it rests on the base plate 1. If screwed in further, the end 5 of the magnetic body 2A would then be raised and, as described above, locked around the rolling edge 20. pivots so that the magnetic body 2A can then be easily removed from the base plate 1 because of the magnetic attraction force that is only effective in this position and is lower than the adhesive force.
- FIG. 1 Another embodiment of a formwork system according to the invention is shown in FIG.
- the lifting bracket 14 is inserted in an adapter guide 22 with a precise fit.
- the lifting bracket 14 can be removed upwards from this adapter guide 22.
- the adapter guide 22 is integrated in an H-shaped formwork 23, which is shown with hatching, it being possible to recognize from a contour 24 shown in broken lines that an adapter guide 22 can be used with H-shaped formwork 23 of different sizes, whereby it is integrated into the formwork at different depths but always at the same height above the base plate 1.
- the lifting rods 12 are supported on the lifting bracket 14 by means of springs 25 in the form of a packet spring washers. When the lifting bracket is lifted off the base plate 1, as shown in FIG. 3, these springs are relaxed.
- FIG. 5 shows in the drawings a) to c) how this magnetic body 2A is detached from the base plate 1.
- One of the two lifting rods 12, 13 is raised with a corresponding lever 26, which is placed under a corresponding disk 27, whereby the magnetic body 2A lying flat on the base plate 1 is lifted on one side. This creates a wedge-shaped gap 28 between the underside of the magnet body 2A and the base plate 1.
- this gap 28 causes the magnet 2 to no longer adhere to the base plate 1 with its full adhesive force, but rather only one between them less magnetic attraction acts. This has the consequence that on the other lifting rod 13 the corresponding spring 25 can also pull the lifting rod 13 upwards, so that the magnetic body 2A, as shown in FIG. 5c), is completely lifted off the base plate 1.
- the formwork 14A is also stored until it is used again. Then the magnetic body 2A with the associated lifting bracket 14 is removed from the corresponding adapter guide 22 of the formwork 14A and inserted into another adapter guide of another formwork.
