发明名称 DRAINAGE CHANNEL BASE, ESPECIALLY FROM POLYMER CONCRETE
摘要 The invention relates to a drainage channel base, especially from polymer concrete. The aim of the invention is to allow for easy coupling and exact alignment of the individual channel partial elements by a special design of the sides. To achieve this, the sides of the channel in one of the two U-shaped limbs (2a, 12a) are provided with a web (3, 13) that extends, in the position of use, in a substantially vertical and outward relation. The other U-shaped limb (2b, 12b), in the position of use, is provided with a substantially vertical groove (4) for engaging with the web of an adjacent channel, the length of the respective groove (4, 14) in the vertical extension, both upwards and downwards, being larger than the length of the corresponding web (3, 13).
