Problems solved by technology

In this respect, the transport of precast concrete elements according to the specifications of the precast elements is logistically costly
In addition, the prefabricated parts must be transported to the corresponding positions of their parts at extremely high levels and connected to each other on site using expensive special cranes
[0010] The disadvantage of these methods is that they are either rather complex and expensive or cannot be applied in practice, this refers in particular to the so-called vertical extrusion method
Especially in the case of wind power plants, this results in a very expensive overall system and consequently also a rather high price for the electricity produced later with this plant

Embodiment Construction

[0060] The name extrusion is used below, although it is not commonly used in the field of concrete construction. Typically when extruding plastic or other hardenable viscous materials extrusion is done in a continuous process through a nozzle. For this purpose this material—the extrudate—is melted and homogenized by means of heating. Build up the required pressure while flowing through the nozzle. The material solidifies after being discharged from the nozzle. The cross-section of the geometry thus produced corresponds to the nozzle used or to the hole pattern arranged behind it.

[0061] The invention relates to the fabrication in situ of longitudinal concrete elements 20 extending in the vertical direction. The invention is particularly suitable for the manufacture of towers (eg wind power plants), columns, electrical towers and piers (eg of bridges or drilling platforms). Such concrete elements are constructed on site, that is to say directly at a defined location (loca...

Abstract

The invention relates to a longitudinal concrete member extending vertically such as a device for wind power generation tower possessing an inner template, an outer template; a gap is between the inner template and the outer template; height is smaller than concrete member (20) to be built. Multiple pumps are employed to pumping concrete into gap by a high pressure, and the concrete member (20) extrudes vertically from the gap during concrete curing process. A top cover (24) is conveyed upward following concrete member rising, the top cover is used for lifting and mounting all kinds of member.

Description

technical field [0001] The invention relates to a method and a device for vertical extrusion of concrete elements according to the preamble of claim 1 or 14 and to a correspondingly produced wind power tower according to the preamble of claim 22 . [0002] This patent application claims priority from PCT application PCT / EP 2005 / 009319 filed on August 30, 2005 in the name of the applicant named at the beginning. Background technique [0003] The construction of longitudinal concrete elements extending vertically in different areas of a high-rise building is challenged. This has always been done in a similar manner in the hitherto known construction technology. The foundation is dug in the ground when construction begins. The first floor of the building is formed on the foundation, in which the concrete is poured in the formwork, and the concrete hardens after a certain period of time. After the hardening of the first storey, the formwork is removed and installed on the upp...
