About TERAJOINT® Free Movement Joint 1. Product Properties TERAJOINT® is a prefabricated leave-in-place joint system designed to create (construct) formed shrinkage free movement joints, consisting of heavy duty arris armoring, permanent formwork, and a load transfer system. The arris armoring is provided by 40 × 10 mm cold drawn steel profiles, which are connected by yieldable plastic bolts. The profiles are anchored into the slab by means of a number of 10 × 100 mm welded anchors, and one of the profiles is welded onto the steel divider plate, which has the load transfer system positioned and...

Information TERAJOINT® with foam Peikko can deliver TERAJOINT® with closed cell polyethylene foam to the places where slabs are cast in the cool condition and thermal expansion is significant. The thickness of the foam (tf) can be 5 / 10 / 15 mm. tf Peikko Group’s production units are externally controlled and periodically audited on the basis of production certifications and product approvals by various independent organizations.

Resistances of the TERAJOINT® dowels are determined according to UK Concrete Society TR34.4 published August 2013. Table 9. Load transfer and required verifications for single plate dowels. P Load transfer Punching shear at the face of the loaded area Punching shear on the critical perimeter Bearing/bending capacity of dowel Shear capacity of dowel TERAJOINT® and TERAJOINT® Strong Free Movement Joints

Table 10. Design resistance of single dowel in shear P, and bearing/bending P , [kN] according TR34.4 for Design resistance [kN/m] covers all required verifications listed in Table 9. The punching shear resistances are calculated for plain concrete without any kind of additional reinforcement and according to TR34.4 the same approach should also be used for steel and macro-synthetic fiber reinforced concrete. If resistances for other joint openings or concrete grades, or slabs thicker than 250 mm are needed, please contact Peikko Technical Support. VERSION: PEIKKO GROUP 06/2020

Selecting TERAJOINT® Free Movement Joint TERAJOINT® is selected according to following criteria: • • • Slab depth. It is recommended that the joint depth, TERAJOINT® height, is at least 10 mm shallower than the slab depth. Advisable slab depths are stated in Tables 4 and 5. Designed joint opening. For joint openings of up to 15 mm wide, we recommend TERAJOINT® TJ5 or TERAJOINT® TJ6. For joint openings from 20 to 30 mm wide, TERAJOINT® TJS8 is recommended. Whereas for pile supported slabs, we would only recommend the use of TERAJOINT® TJS8. Environment. For internal floors, we would suggest the...

Installing TERAJOINT® Free Movement Joint General The handling of TERAJOINT Free Movement Joins must be done by following safety instructions. The free movement joints on site must be protected from weather, damage during handling and possible damage during removal on the packing. Joints should be stored in dry and sheltered conditions. Before use, the free movement joints are inspected visually for completeness and any signs of damage that might have occurred during transport or storage. The assessment of the products is based on the assumption that during the estimated working life no maintenance...
