Precast Plant Dobler is Manufacturing with Strengthened Filigran EV
lattice girders
Special building projects require special building elements. In the city of Kempten/Germany prehistoric remains of the St. Erasmus chapel shall be opened to the public as a show room. The underground space of this former chapel of the 12th century including the historic external walls should be spanned without using columns. The span required thus account for about 10 m to 13 m.
The engineering consultancy of Dr. Schütz Ingineure based in Kempten selected the static system and the dimensioning. The slab was chosen to be 34 cm thick and constructed as a semi-precast slab by Dobler GmbH & Co. KG, Kaufbeuren/Germany. In order to limit the deflection, prestressing elements were included for a subsequent bond. The slabs were manufactured as semi-precast Filigran floor slab. Parts of the floor slab were born on bore piles and protruded them. This required slab lengths of up to 15.3 m.
The transport and installation state of these extraordinarily dimensioned slabs had to...
