In 1997 Sipral delivered interior steel glazed structures to the store Na Smetance, Prague 2. In the store interior a new in-built ceiling made of a bearing steel structure with a glazed floor was built to which a smith-made steel staircase leads.Ceiling areais bordered with glazed safety railing and the whole space is zoned with glazed dividing partitions.
The bearing structure of a raised glazed floor is a bolted steel structure anchored in the following building structures and creating a bearing grid for mounting of the floor glass units. The floor glass panels of 1000 x 500 mm are made of 26 mm thick safety laminated glass. They have ground upper visible edge and their upper walk-able area is anti-slip through sand-blasting in the pattern of strips. Joints between individual glass units are sealed.
A staircase made of steel welded sheets and single railing of steel profiles form part of the structure. The staircase surface treatment is sand-papered and colour-less varnished.
There are glazed interior walls between the floor and the raised floor up to the ceiling structure as well at the side of the staircase flight to create divisions of rooms. They are fitted with safety glass units of blue and green colour with a milk foil and clear tempered glass sheets, 12 mm thick.
