The permanent intermediate floor cover and roof templates are made of polystyrene foam EPS 100. The templates are 0.6 m wide (from 2 to 12 m); their height can be from 180 to 320 mm. There are 3 penetrated templates embedded (112 mm high). To increase the load-bearing capacities and affix finishing cover, polystyrene foam holds 2 U type metal profiles (120 mm high). The templates can be used both as intermediate floor cover templates and for roof layer concreting with a tilt up to 20o.Site preparationBefore mounting a permanent intermediate floor cover and roof templates, one must prepare a temporary telescopic inventory supports and beams. The first supporting beam must be placed directly to the load-bearing wall. The supporting beam must be at least 100 mm wide. The supporting beam is to be mounted perpendicularly to the perforated steel galvanized profiles embedded in the cover elements. The maximum distance between temporary supports shall be 1.5 m. These supports must be made of wood or metal.Form placementMounting polystyrene foam cover form is simple and can be completely done by one or two workers. The works must be started at the end wall. The cover template elements must be attached with a groove connection. To avoid concrete mass pouring in the element canals, the canal openings before mounting these elements must be closed (sealed) with special polystyrene foam plugs delivered with the cover template elements.
