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
