Additional devices when laying slabs with the Optimas Vacuum tube lifter
Joints spacing aid
The Optimas - Joints spacer aid attached on suction pads enables laying of slabs with at a precisely predetermined distance. The time-consuming use of jointing irons or other aids is no longer necessary. A further positive effect is that the joints spacer can be used as a stop when the panels are sucked from the package. The suction plate is therefore always centred on the panel.
Depending on the slab size 2 - 3 pieces are needed. Each joints spacer is supplied with 4 spacers in the following thicknesses: 3, 4, 6 and 8 mm. These spacers are very easy to exchange.
Maintaining suitable joint widths and a completely filled joint are the most important conditions for a load-bearing and stable paving surface. Depending on the nominal thickness of the paving stone, the following joint dimensions apply:
Nominal thickness < 120 mm: minimum 3 mm, maximum 5 mm Nominal thickness ≥ 120 mm: minimum 5 mm, maximum 8 mm
Clamping device Ankerfix "Solo / AP"
(Utility model protection Nr. 20 2014 009 734.8)
(Utility model protection Nr. 20 2014 009 734.8)
Different shifting protections (anchors) are available on the market - normally supplied
by the producers of the relevant concrete elements.
Ankerfix "Solo" can be fastened to the slab to be laid with a quick release fastener and holds anchor in place. As far as we know, the Ankerfix "Solo" can be used for all anchor solutions available on the market.
Ankerfix “AP” is attached to the suction pad and holds the individual anchor solution by magnet.
With both solutions, the anchor is set to the specified position by gravity directly when the slab is placed.
In accordance to the “Road and Transportation Research Association (FGSV)” https://www.fgsv.de/en/home.html is needed for large formats of pavers and slabs as protection against displacement of rows in non-directional traffic.
In recent years, shifting safety devices have already been installed in several hundred projects. To date, no problems have been reported in these areas of application.
