IV. Anchors
–
placing in concrete
The installation of the anchors is a key stage to the whole assembly process of the cage and its further proper
functioning, so please pay particular attention and install the anchors with high precision. The anchors are delivered
ready for installation
–
the screws situated in the upper plates of the anchors are fully screwed down and their threads
are protected by rubber sleeves. If concrete plasters the threads of the screws, it will be impossible to install the
pillars. Before installation please make sure the screws are fully screwed down and the threads are secured with
rubber sleeves.
All the anchors must be positioned in concrete foundation blocks towards inside the cage (throwing circle), according
to the direction lines on the anchors plates (see Draw. no. 4, p. 18). Each anchor must be embedded in the foundation
block in such a way that its upper surface is exactly horizontal (then the pillar is vertical) and flash with the target
surface of the throwing facility (see Drawings no.: 1, 2 and 3; p. 15 and next).
ATTENTION!
The anchors should be placed in the concrete of the class B20 (C16/20) quality or
higher.
Each time the anchor is put into the foundation the concrete should be mixed, so that it
covers tightly the ribbed bars and there are no air chambers inside. During the concrete setting the
foundations should be moistened (in the first week twice a day, in the second week once a day).
You ought to wait minimum 2 weeks before you proceed with the installation of the pillars.
