Definitions
- the invention relates to column formwork for use in concrete construction.
- Column formwork is used in concrete construction for the manufacture of columns, columns or similar concrete elements.
- winding formwork made of sheet metal, cardboard or plastic has been used more and more recently.
- the outer formwork tube which essentially serves to hold the formwork together, is made of cardboard or cardboard. After concreting the column and setting the concrete, the outer formwork element can be removed by tearing it in using an integrated rip cord.
- a column formwork which consists of a multi-layer wound flat material.
- the flat material is a paper web coated with polyethylene. Due to the multi-layer winding, paper and polyethylene layers alternate with this column formwork in the wall of the formwork tube.
- DE 296 09 259 discloses a column formwork which consists of a pipe section divided along its longitudinal axis. To hold the formwork together, connecting means are provided in the area of the dividing line. To produce this column formwork, a piece of pipe is slit once along its longitudinal axis. In order to ensure simple formwork removal, it is proposed to manufacture the column formwork from a plastic that can be bent open when the formwork is removed. A formwork auxiliary material is attached to the inside of the column formwork, which prevents the shape of the mold from the dividing line.
- These known column formwork have several disadvantages in common. On the one hand, the formwork has an extremely large volume and, as a result, causes problems, particularly in transport, which are reflected in high costs.
- the interior of the column formwork intended for filling with concrete is nothing more than a dead volume during transport, which means that only a very small number of pieces can be transported per load.
- This problem also has the column formwork according to DE 296 09 259, since it is dimensionally stable plastic pipes that can only be briefly bent up when the formwork is removed by applying sufficient force.
- column formwork described above is a one-way product, since the outer formwork element is removed from the hardened concrete by tearing it open. This prevents the column formwork from being reused.
- column formwork according to DE 296 09 259 this problem is only partially solved.
- the outer part of the formwork can be reused, the necessary inner lining with e.g. a tube made of thin cardboard is a disposable product.
- the present invention is based on the idea of not using prefabricated tubes as column formwork in concrete construction, as previously, but sheet materials which are equipped with connecting profiles, by means of which a form-fitting connection of two opposite edges of the sheet material is possible.
- the material from which the fabric is made must meet two contrary conditions: on the one hand it must have sufficient strength to withstand the pressure of the filled concrete, on the other hand it must have sufficient elasticity so that it can be easily bent into a tube , In particular this tube must remain "dimensionally stable", ie circular in cross-section, under concrete pressure, ie after the concrete has been poured in.
- the column formwork according to the invention for use in concrete construction consists of a sheet-like structure forming the formwork and at least one connecting profile which is provided for the positive connection of two opposite edges of the sheet-like structure and thus for the formation of a pipe piece, at least the surface of the connecting profile facing the sheet-like structure being essentially constant Has curvature that corresponds essentially to the curvature of the pipe section. This ensures that the column formwork takes on a round shape. When using connecting profiles without curvature, the curved surface structure would take on a slightly teardrop shape and thus lead to unsatisfactory results for the concrete parts. Slight differences between the curvature of the connecting profile and the curvature of the pipe section are tolerated in the context of the present invention, since acceptable results are nevertheless achieved.
- the column formwork according to the invention can be transported in large quantities without problems before bending to a flat tube.
- the flat structure consists of an elastic plastic.
- a material fulfills the two conditions mentioned above particularly well, namely sufficient dimensional stability after the concrete has been poured in and at the same time sufficient elasticity which permits problem-free bending into a tube.
- Such column formwork has the great advantage that no disposable materials such as the cardboard commonly used are provided, which enables the formwork to be reused several times.
- the two opposite edges of the fabric must be connected to each other in a form-fitting manner. For this purpose, at least two connection profiles are generally used. These connection profiles are advantageously mounted flush with one edge of the fabric on the fabric.
- connection profiles can in principle also be attached to the flat structure at a short or even greater distance from the edges to be connected.
- the springs described below for connecting the connection profiles must be adapted accordingly in their dimensions or replaced, for example, by flexible bands.
- Flat structures with a thickness of 1.4 to 4 mm are particularly suitable 2.5 mm, very particularly preferred are those with a thickness of 1.5 to 2 mm.
- the surface of the connecting profiles facing away from the flat structure can additionally be provided with an essentially constant curvature, this curvature then differing from the curvature of the pipe section. In this way, a connection profile can be used for column formwork with different diameters.
- column formwork according to the invention can be used for concreting columns with a widely varying diameter, in principle even for concreting columns with any diameter, column formwork with a diameter of 100 to 2000 mm, in particular 200 to 1000 mm, which is common in concrete construction, is preferred. Diameters from 200 to 450 mm, from 250 to 500 mm, from 500 to 900 mm and from 600 to 1000 mm are particularly preferred.
- the connecting profiles can be attached to the fabric in various ways, namely e.g. by gluing, riveting, nailing or welding. It is particularly preferred to glue the connecting profile and the flat structures because this does not cause any visible traces in the finished concrete parts.
- Particularly preferred embodiments of the present invention are column formwork with connecting profiles which have an extension of 1 to 50%, in particular 3 to 25%, of the pipe section diameter in the direction of the pipe section tangent perpendicular to the axis of the pipe section.
- connecting profiles are very particularly preferred which have an extension of 5 to 15%, in particular around 10% of the pipe section diameter in the direction of the pipe section tangent perpendicular to the axis of the pipe section.
- connecting profiles are preferred which have an extension of 10 to 100 mm, in particular 20 to 75 mm, in the direction of the pipe section tangent perpendicular to the axis of the pipe section.
- Connection profiles are particularly preferred which have an extension of 30 to 50 mm, in particular 35 to 45 mm, in the direction of the pipe section tangent perpendicular to the longitudinal axis of the pipe section.
- connection profiles can be made from any type of sufficiently dimensionally stable material.
- the connecting profiles are preferably made from plastic, particularly preferably the connecting profiles are made from polyester, from a fiber-reinforced plastic, in particular from glass fiber-reinforced or carbon-reinforced plastic, particularly preferably from glass-fiber reinforced or carbon-reinforced polyester.
- the connecting profiles extend in the direction of the axis of the pipe section over the entire length of the pipe section.
- the edges of the fabric can be positively connected over the entire length of the column formwork with particularly high force and accuracy.
- connection profiles can basically be mechanically connected to each other in any way known from formwork technology, e.g. with the help of clamps, wedges, locks or bolts.
- connecting profiles are preferred which have grooves and tongues.
- a tongue of one connection profile engages in a groove of the other connection profile with a precise fit.
- the stable cohesion of the edges of the fabric is e.g. guaranteed by a bolt that is guided through holes in the connecting profiles and then screwed.
- FIG. 1 shows a section of a cross section through a column formwork according to the invention
- Fig. 2 shows a part of a cross section through a column formwork according to the invention with a larger diameter compared to the column formwork of Figure 1.
- Figure 1 shows a section of a cross section through a column formwork.
- the fabric 1 is equipped with the connecting profiles 2 and 2 ', which are each attached to the edges 3, 3 ' of the fabric.
- the surface 4, 4 'of the connecting profiles facing the fabric 1 has a constant curvature, the curvature essentially corresponding to the curvature of the pipe section. This ensures that the column formwork takes on an exactly round shape.
- the surface 5, 5 'facing away from the fabric Connection profiles also have a constant curvature, the surface 5, 5 'of the connection profiles shown being more curved than the surface 4, 4 ' .
- the edges 3, 3 'of the fabric 1 have a high accuracy of fit.
- the connecting profile 5 is equipped with two springs 6, while the connecting profile 5 'has two corresponding grooves.
- each of the two connecting profiles can also be equipped with a tongue and a groove.
- the connection of the two connection profiles and thus the positive connection of the two edges of the fabric takes place by engaging the springs 6 in the corresponding grooves.
- the longitudinal seals 7 prevent water from escaping through the connecting profiles 2, 2 ' .
- the securing of the connection which is still required is not shown by a clamp which overlaps the two connecting profiles 2, 2 ' or a bolt which is guided through the two connecting profiles 2, 2 ' and then screwed together.
- Figure 2 also shows a section of a cross section through a column formwork.
- the extension t of the connecting profile 2 in the direction of the pipe section tangent perpendicular to the axis of the pipe section is highlighted.
