OMNIA precast concrete permanent formwork planks and panels are generally delivered to site on articulated vehicles ready for immediate offloading and placing onto prepared supports. Depending on the specific requirements of the contract, various support details can be considered.
|
|
|
For Health and Safety purposes, OMNIA panels will be supplied with the maximum bearing possible, which may exceed the nominal figures given below.
|
|
|
On Steelwork
|
|
|
Panels require a nominal bearing of 55mm.
|
 |
|
|
Panels bearing at differential levels may require a compressible bitumenised strip to prevent point bearing and excessive grout loss.
|
 |
|
|
Shelf angles must be of such a length as to allow the end of the panel to pass the top flange during placing, and be set at a height that will allow continuity.
|
 |
|
|
On In-Situ Concrete
|
|
|
Support panels on the formwork and cast a fully homogenous slab. The OMNIA preferred option.
|
 |
|
|
When supported on 'half-cast' beams, links must be so arranged to allow 65mm nominal bearing.
|
 |
|
|
Where less than 40mm bearing is available, a suitable temporary prop must be in place before placing the panel and left in place until the in-situ portion has reached working strength.
|
 |
|
|
On Masonry
|
|
|
Panels require a nominal bearing of 60mm and are usually set back 30mm from the cavity.
|
 |
|
|
Two OMNIA panels can be supported on 140mm wide load bearing blockwork with a 20mm gap between.
|
 |
|
|
Where less than 40mm bearing is available eg. on 100mm walls, temporary props should be in place prior to placing the panels.
