Definitions
- the present invention relates to a method for producing tower segment precast concrete parts of a tower of a wind turbine, a precast concrete manufactured by the method, a formwork cover for placing on a formwork, a formwork unit for producing precast concrete parts and the use of a low viscous resin. Finally, the invention relates to a wind turbine.
- a leveling layer on the construction site can be applied to each flange of a precast concrete part.
- This leveling layer has to harden, which in turn means compliance with minimum meteorological requirements required, which are dependent on the material of the compensation layer. If these minimum requirements are not met or the leveling layer has been applied improperly or negligently, there is a risk of defects or the risk of an insufficient setting of the leveling layer.
- WO 2009/121581 A1 shows a method for producing precast concrete parts.
- the concrete is poured into a mold with a flat bottom to form a flat underside.
- a leveling layer is applied to a bottom surface opposite abutting surface of the precast concrete part.
- the precast concrete element is set down on an exactly horizontally oriented surface and the leveling layer on the upper side is removed plane-parallel.
- a method for producing a tower segment precast concrete part of a tower of a wind turbine, in particular a tower segment is provided.
- a low viscosity material for a leveling layer is applied to a flange of the precast concrete part. This can be done optionally as soon as the concrete has reached a predetermined minimum strength.
- the invention is based on the finding that the invention allows the "mortaring" of the joint on the construction site during the erection of the tower in the production hall can be laid ..
- the invention allows the "mortaring" of the joint on the construction site during the erection of the tower in the production hall can be laid ..
- a Tolerance of 0.1 mm which is more accurate by a factor of 100.
- a higher Process reliability through significantly reduced susceptibility to errors, for example, achieved when mixing the filling and also the health risks inherent in the processing of resins on the site are thus avoided.
- the thickness of the compensation layer is up to 10 mm, in particular up to 5 mm.
- the thickness of the compensation layer is up to 10 mm, in particular up to 5 mm.
- the formwork is closed by placing a formwork cover and the material for the leveling layer is supplied at a predetermined pressure through at least one filling opening in the shuttering cover.
- a clearly defined cavity above the flange of the precast concrete part can be created, which is filled with resin, so that forms an equally well-defined leveling layer.
- predetermined areas of the flange e.g. Openings for ducts or anchorage threaded bushings to be kept clear of the leveling layer, predetermined areas of the flange are covered with seals of predetermined thickness before the shuttering cover is fitted, and these seals are held down by the formwork cover.
- the leveling layer should have an E-modulus that corresponds to at least 70% of the modulus of elasticity of the concrete. It has surprisingly been found that the required mechanical properties of the compensating layer can be achieved even if the modulus of elasticity lies in a range of 5,000 to 10,000 MPa, provided that a predetermined layer thickness is not exceeded.
- a given surface roughness is required. This should preferably be in a range of 60-150 pm.
- the invention also relates to a shuttering cover for placing on a formwork in the manufacture of a precast concrete part.
- the shuttering cover has an underside with at least one recess, which has a predetermined width in the radial direction of the cover and a predetermined depth.
- the formwork lid also has at least one filling opening for filling in a material of a leveling layer.
- the formwork cover comprises a recess formed on the underside of the formwork cover facing the formwork with a width predetermined in the radial direction of the formwork cover and a predetermined depth and with at least one fill opening for the material of the leveling layer.
- the width in the radial direction of the shuttering cover can be dimensioned such that it corresponds to the width of the flange on which the compensation layer is to be formed.
- the predetermined depth and the thickness of this leveling layer can be defined exactly. Since the formwork lid completely covers the upper opening of the formwork on which the flange is formed, at least one filling opening for the material of the compensating layer can be provided. In order to be able to recognize that a sufficient amount of material has been supplied through the filling opening, at least one outlet opening for the material of the compensating layer is provided. If the material of the compensating layer exits the formwork lid through this outlet opening, the material for the compensating layer is sufficiently distributed. In addition, the air displaced by the inflowing material can escape through the outlet opening, so that cavities (that is, unwanted air pockets in the material) can be safely avoided because the air displaced by the material of the compensating layer can escape.
- the filling opening and / or the outlet opening are formed as a connecting piece for a hose. Accordingly, hoses can be connected there and through the hoses, the material for the leveling layer can be fed in and out cleanly.
- the shuttering cover (vertical) on the upper side standing side walls and a side wall connecting the cover plate.
- the box shape thus obtained gives the shuttering cover a higher bending stiffness and thus a higher dimensional accuracy.
- stiffeners are arranged essentially parallel to the side walls between the upper side of the covering cover and the underside of the cover plate, which reinforces the bending stiffness and thus the dimensional stability even further.
- the invention also relates to a gasket for use with a formwork cover described above.
- the seal has a two-part design with a deformable part and a non-deformable part. The deformable part is placed on a sealed part of the precast concrete part and the non-deformable part is placed on the deformable part, thus achieving a vorgebare height.
- the shuttering cover can hold down the seal and reliably press on the concrete so that there the low-viscosity material for the leveling layer can not flow.
- the seal is developed such that the deformable part is designed annular and provided with a support surface of predetermined width, on which lies the non-deformable part.
- the invention also relates to a formwork unit for producing a precast concrete part.
- the formwork unit has a formwork for receiving concrete, a circuit cover described above and a seal described above.
- the invention also relates to the use of a low-viscosity resin for producing a leveling layer in the manufacture of a precast concrete part, wherein the resin is applied to the flange of a precast concrete part.
- a leveling layer which can replace the production of a mortar joint on the construction site, already be formed in the production of precast concrete in the factory under controlled conditions.
- the wind turbine relates to a tower of a plurality of precast concrete elements, which are produced or produced by the method according to the invention.
- the construction of such a tower is easy, fast and weather-independent to implement and thus allows the construction of a wind turbine in no time under exclusion of multiple sources of error.
- the required crane times are achieved because the individual assembly steps take less time and the crane is thus available for other work faster.
- resin mortar as a leveling layer on the construction site can be avoided.
- resins or resin mortars used are known as allergy-causing substances and thus possibly impair the health of the processors of these resins.
- resin mortar resin can now be used.

- a formwork for the precast concrete part is provided in step S1.
- the formwork is filled with concrete.
- the concrete has reached a predetermined minimum strength or the concrete has been abraded and in step S4 a low-viscosity resin is applied in the region of the flange of the precast concrete part and then hardens there in situ.
- the filling of the resin as material for the leveling layer can take about 2 hours. after filling the Concrete in the form done. The resin is pressed at about 31 / minute and this process takes, depending on the size of the formwork and the resulting volume about 3 to 10 minutes.

- the recess 32 is formed on the underside of the shuttering cover 30 and is located by placing the shuttering cover 30 on the formwork 10 above the flange of the precast concrete 20.
- After placing the shuttering cover 30 on the formwork 10 is a low-viscosity resin through the filling opening 31 in the recess 32 filled. Due to the low viscosity of the resin, the resin can easily spread along the flange of the precast concrete 20 and also compensates for existing bumps.
- the resin forms a horizontally leveled surface and - assuming a horizontally extending underside of the precast concrete part - a plane-parallel surface.
- the leveling layer of the low-viscosity resin has a thickness of at most 10 mm, and more preferably not more than 3 or 4 mm. With such a layer thickness, the leveling layer has advantageous mechanical properties, which also allow the use of a material with a relatively low modulus of elasticity in the range of 5,000 to 10,000 MPa.
- transverse tensile stresses are problematic in concrete because it has a relatively high compressive strength but only a relatively low tensile strength. With a layer thickness of max. 4 mm, however, are not to be feared on the concrete acting transverse tensile stresses.
- the resin is poured into the mold about two hours after pouring the concrete. Then, on the one hand, the concrete has reached a given minimum strength, but on the other hand, it has not completely set, so that the resin can still bond to the concrete. After about three to four hours, the precast concrete and the resin has reached a sufficient strength and can be switched off.
