Definitions
- the invention relates to a segment formwork for circular buildings, with a scaffold with uprights and runners and formwork panels attached to it at certain points, the runners being polygonal and adjustable in angle.
- the runners are formed by articulated bolts which are fastened to vertical profiles which form the uprights.
- the vertical profiles support the formlining and the binding is made from an inner to an outer hinge.
- Formwork segments of this type can be adapted to different building diameters due to the design of the runners as articulated bolts, but when the radius of curvature changes, the formwork skin must be completely separated from the uprights. Furthermore, in many cases the uprights of the inner and outer formwork would have to be realigned to each other.
- the object of the invention is to provide a segmental formwork of the type mentioned at the outset, in which the radius of curvature can be changed without the formwork panels of the formlining being removed from the framework supporting it, i.e. from runners or stanchions. This should be possible both with an exterior and with an interior formwork.
- one embodiment of the invention provides that the uprights are arranged between the runners and with them , preferably by welding.
- the uprights are advantageously arranged centrally at the kinks of the runners and in the case of an outer formwork between the kinks of the runners.
- the runners are arranged at the edges of the formwork panels and have projections, so that when formwork panels are placed one on top of the other, the runners that are in contact with one another interlock positively.
- the formwork panels are fastened to the uprights which have horizontal slots through which the fastening bolts or the like. protrude.
- the lengthwise differences in the formlining can be compensated for by adding or removing supplements, the supplements being able to be applied between the formlining or between the uprights.
- the runners preferably the runners, are arranged at the upper edge of the formwork panels clamping jaws are clamped on which tie rods engage. These clamping jaws can be moved along the profiles of the runners, so that when the curvature of the formlining changes, the tie rods can be quickly and easily aligned with the new geometric center of the circles of curvature of the inner and outer formwork.
- runners lying on top of one another are preferably held together by means of wedge connections.
- Wood since a continuous curvature can be achieved with such formwork panels and they also have the necessary stiffness, so that they only have to rest against the runners in places.
- the runners and uprights form a closed frame which carries several formwork panels and can be connected to a similar frame.
- FIG. 1 shows a schematic view of a segment formwork according to the invention
- FIG. 2 shows a horizontal section through the segment formwork according to the invention
- FIG. 3 shows a vertical section
- FIG. 4 also shows a vertical section in the connection area of two formwork rings standing on top of one another
- FIG. 5 shows an enlarged detail from FIG. 2.
- different segment formwork 1 can be put together to form a large segment 2.
- 3 denotes an already concreted concrete section.
- Each segment formwork 1 has a closed frame 4, which is formed by runners 5 and 6 pillars.
- the uprights 6 are formed by uprights 6 *, which are each arranged between two runners 5 and connected, preferably welded, to them.
- the runners 5 are formed by profile iron. In the embodiment, they are U profiles.
- the profile bars are provided with slots 8 at their kinks 7, the flange 9 of the profile facing the formwork not being cut.
- tabs 1 or the like are at the kinks. provided that connect the adjacent web sections 9 'to each other.
- the tabs 10 are provided with elongated holes, for example, through which the fastening screws 11 protrude. The curvature of the runners 5 can thus be easily adjusted by loosening the fastening screws 11 at the kinks, whereupon the runners 5 are bent at the kinks 8 and adapted to the desired curvature. Then the clamping screws 11 are tightened again.
- the formwork boards 12 lie directly against the runners 5 and the uprights 6.
- the formwork boards 12 have a continuous curvature, so that there are free areas 13 between the runners 5 and the formwork boards 12.
- the shuttering boards 12 are made of multi-glued wood and can be clad with sheet metal on the concrete side. These formwork boards 12 can be easily bent on the one hand and on the other hand have sufficient rigidity and tension properties so that they are not pushed against the runner 5 by the freshly poured concrete in such a way that a polygonal formwork surface would result.
- the uprights 6 are arranged at the kink points 8 in the internal formwork, but in each case only welded to one runner section 5 ′.
- the uprights 6 of the outer formwork are arranged centrally between the buckling points.
- the formwork panels 12 are fastened directly to the uprights 6, namely they have horizontally extending elongated holes through which the fastening screws of the formwork panels 12 protrude. These fastening screws can be displaced within the elongated holes, so that the formwork panels 12 do not have to be removed from the uprights 6 when the curvature of the runners 5 changes.
- clamping jaws 14 are held on the rotors 5 by means of clamping screws 15 and clamping jaws 16.
- the tie rods 15 are anchored in the clamping jaws 14.
- the tie rods 15 are screwed into nuts 16.
- the nut 16 on one side for example in the case of the inner formwork, can be detachably fastened to the clamping jaw 14 and thus practically forms an internal thread of the respective clamping jaw 14.
- the binding rods 15 can therefore be inserted and screwed in from one side of the formwork.
- the tie rods 15 are pushed through the formwork from the right in the embodiment of FIG. 4 and into the left, with the
- the right nut 16 is then screwed on.
- the runners 5, which are each arranged on the edges of the formwork panels 12, have interlocking projections 17.
- One formwork ring can thus easily be placed on the other, centering itself automatically. This makes climbing the formwork easier.
- the upright sections 6 are formed by square tubes, but I profiles or U profiles could also be used.
- segment formwork With the segment formwork according to the invention, it is advantageously concreted in such a way that a large segment 2 is built up, for example, for the inner formwork.
- a ring section with a height of preferably 1.5 m is set up and connected to the inner formwork by means of the tie rods 15. Before this, the reinforcement can be inserted in full.
- the interconnected section is then filled with concrete and compacted.
- a second formwork ring can then be placed on the outer formwork on top of the previous one.
- This formwork ring is in turn connected to the inner formwork and the concreting process is repeated.
- the adjacent runners 5 of adjacent formwork rings or formwork panels 12 are advantageously connected to one another by pin-wedge connections 18.
- the segment formwork according to the invention enables individual formwork segments 1 to be placed very quickly against one another and thus to rapidly climb the formwork, so that with the previously described method can be worked.
- the embodiment of the segmental formwork according to the invention enables it to be quickly adapted to different diameters of round buildings.
