Steel part for load introductionof steel rods into the CLT- plate

Joint of the CLT- plate (necessarydue to limited production length)

Detail of the steel trestles: drilledholes for the anchoring of thesuspension rods

Steel trestles (tubes) for thesuspending system of the CLT-elements

Detail: Roof above offices

Joint rips – wall: by means ofslotted- in steel plate with dowels

Joint deck (CLT) – wall:by means of bearing of on the CLT-element of the wall and selftapping screws

Bearing area of the roof above offices:bearing on reinforced concrete walls by means of slotted-in steel plates and special elastomeric layers

Assembling / Erection Offices

→ High level of pre-fabrication for wall and roof elements

→ Lifting by means of auto-cranes
