CONCRETE KERBSTONE

Sub-construction

Terrace system with concrete kerbstone

The concrete edge stone offers you the option of designing the superstructure as an open or closed deck. The two construction variants essentially differ in the construction heights, which are realised by our megawood® construction beams 80 x 60 mm and 40 x 60 mm.

The megawood® construction plan with concrete kerbstone tells you exactly how this works.

Installation heights


Concrete kerbstone
Basis construction

with construction beams 40 x 60 mm

Screw
(7.5 x 92 mm, pre-drill!)

Construction beam
(40 x 60 mm)

Rubber pad
(10 x 100 x 60 mm)

for height compensation measuring 3/10/20 mm

Concrete kerbstone
(50 x 1000 x 250 mm)

(available from building material dealers)

Locking clamp

10 mm gap

- Gravel formation level with a 2 % gradient (in longitudinal direction of the plank)
- Example with 21 mm floorboards

Concrete kerbstone
Elevated construction

with construction beams 80 x 60 mm

Screw
(7.5 x 132 mm, pre-drill!)

Construction beam
(80 x 60 mm)

Rubber pad
(10 x 100 x 60 mm)

for height compensation measuring 3/10/20 mm

Concrete kerbstone
(50 x 1000 x 250 mm)

(available from building material dealers)

Groove strip with locking clamp

10 mm gap

- Gravel formation level with a 2 % gradient (in longitudinal direction of the plank)
- Example with 21 mm floorboards

Construction variants


Open gap

min. 2 %
recomm. gradient
Open joints are available with a CB of 40 x 60 or 80 x 60.
Without groove strip/P5 gap profile.

Closed gap

Closed joints are only available with a CB of 80 x 60.
min. 2 %
gradient necessary
With groove strip/P5 gap profile.
A min. 2 % longitudinal gradient of the board is compulsory with an elevated design of min. 161 mm, as is an adequate ventilation from below and the rear respectively (e.g. use of ventilation grilles, keeping distance from rhombus profiles).

Special features in the construction


Laying on mitres for L, U, O-shaped terraces
- Double sub-construction along the 45°section. insert sealing tape into the mitre joint on both sides.
- Only push the floorboard into the mitre profile by 10 mm in order to ensure the expansion.
-When attaching short floorboard sections (that can be fastened to the lower edge with less than 3 locking clamps or clips) on the diagonal or mitre cut, the sections are screwed to the construction beam from above. (M6 x 40 mm screw)

Construction at floor level with ventilation grille
- The terrace deck is constructed at ground level and creates a level circumferential terrain edge.
- A distance of at least 20 mm between the boards and raised, fixed components must always be maintained.
- The ground level deck can be created with a closed joint as long as the compulsory construction height is min. 161 mm, a compulsory min. 2 % gradient is adhered to and circumferential ventilation grilles or other constructional measures are ensured in order to provide an adequate under ventilation or back ventilation.
- Only implement a level floorboard structure with a 5 mm in conjunction with a ventilation
- Use of the ventilation grid (also with „placed-on“ deck or in the event of a closed gap) in order to improve the air circulation beneath the terrace and to increase the service life of the entire deck.

Laying as a deck with herringbone pattern
- A double sub-construction is to be provided at all butt joints.
- The Distanz Fix is positioned between the double construction beam in order to create the clearance of the butt joints.
- When using the Distanz Fix, each of the construction beams are to be provided with a retaining tape next to the Distanz Fix, it is not to be placed on the tape.

Cross bracing structure
- Prerequisite for the cross bracing is a load-bearing substrate (concrete, concrete kerbstone). The structure is built on 20  mm high rubber pads, which are installed at the crossing points of the construction beams to ensure the minimum distance.
- The cross bracing must be securely connected to the substrate.
- The general planning principles of megawood® construction plan terrace system apply.

VARIO FIX for fast deck assembly

Our VARIO FIX substructure system offers you a consistent and well thought-out system in two variants, which is characterised by simple handling, extremely flexible and infinitely variable height adjustment. Thanks to the 360° spherical head, an angle of inclination of up to 10 % can be realised without any problems.
VARIO FIX I (40 - 143)
VARIO FIX II (44-242)
