What is the Load bearing capacity of the Klevaklip Adjustable Bearer Support?
The span table below is designed to provide a load bearing capacity of 350kg per square metre when bearer supports used at the associated heights. The span table should be read in conjunction with Bearer span tables. In some instances the placing (distance between bearer supports) of the Adjustable Bearer Supports will be limited by the span capabilities of the actual bearer itself.
|Maximum Load Area(m2)|
|Bearer Width||Bearer Support Height (mm)||2 Span Continuous||3 Span Continuous|
** When using 45 or 50mm bearers, in order to achieve the above load areas, the bearer must be packed out from to "L-bracket" to ensure the centre of the bearer is directly above the centre of the bearer support column.
How to calculate how many Adjustable Bearer Supports are needed for your deck?
The span table (above) will give you an indication on the minimum number of bearer supports required for your deck. However, the span table should be read in conjunction with Bearer span tables. In some instances the placing (distance between bearer supports) of the Adjustable Bearer Supports will be limited by the span capabilities of the actual bearer itself.
Note:- on a free-standing deck (ie – not attached to a fixed structure), regardless of bearers meeting span requirements, a minimum of six (6) Adjustable Bearer Supports should be used.
How regular along my bearers do I need to put the Adjustable bearer supports?
Whilst the span table provides information on the total number of bearer supports required for your deck, in most instances the frequency of bearer supports required along the length of your bearer will be governed by your actual bearer span tables.
What is the maximum height that I can adjust my bearer support to?
Do not raise the height of the bearer support above "290mm to the bottom of bearer height". At this measurement, there is approximately 18mm of the threaded rod left in the bottom nut. Raising the height above 290mm can compromise the integrity of the product under load.
What is the minimum height that I can adjust my bearer support to?
The adjustable bearer support has a supplied lowest height of approx 175mm. In order to achieve the minimum 160mm advertised height, the bottom 15-20mm of the threaded rod needs to be cut off. You can go down to 143mm by removing the locking nut and cutting approximately 40mm of the threaded rod .This does not compromise the integrity of the product as there is minumal lateral load however, it is good practise to paint the end of the treaded rod cut with metal primer.
Can I install the Adjustable bearer supports over brick pavers?
No, this is not recommended as the pavers do not have adequate structural stability.
