Depending on the type of floor joint the tool offers a variety of load transfer systems including circular dowels rectangular dowels and diamond dowels Peikko Designer 174 FLOOR JOINT provides a design report including utilisation ratios against determined loads The design reports are also available in printout format Peikko Designer 174 FLOOR JOINT is a free web based
Dowel systems Dowels perform the important job of load transfer between adjacent concrete slabs Because a concrete slab only has around 50 of its load bearing capacity at the edges dowels are needed to support the slab help bear and transfer weight and permit controlled movement of the two adjacent slabs technically called the approach and leave slabs
Free Movement Armoured Joint system ensures adequate load transfer in contraction and construction joints and eliminates resistance to joint opening and movement in both horizontal plane directions The system also provides extremely durable edge protection to the concrete slabs particularly when subjected to traffic Our Discontinuous plate dowel load transter
They act as a permanent formwork creating a secure boundary or day joint during the concrete pour They allow the concrete slab to contract in a controlled way to prevent random cracks occurring They protect the construction joint arrises from impact damage once the building is in use saving the expense of repair
