PROJECT:  Renovation of traditional house in Stemnitsa - Pelloponise

CLIENT: Private

BRIEF DESCRIPTION:
 
Renovation of traditional stone house in the village Stemnitsa (Ipsous) - Peloponnese. In the project structural part, the roof was replaced with a new designed according DIN1052, added a balkony and internal flooring.

The roof:
It covers the wall perimeter area of ​​9x11m, has 3 surfaces with the fourth side closed by a pediment which created by the masonry wall (stones), while the opposite side is extended by 1.2m of the perimeter wall, creating a canopy supported on the balcony. Support of the roof is on the masonry wall via a R.C pad 15cm thick and especially on the balcony with wooden columns.

The roof consists of four trusses at 2m. The last, at the balcony side, supports their respective ridges.

The main beams of the trusses are BSH 68/336 (laminated wood) and for the tension chords 2x 68x147 at each truss. The connection of the tension chord to the main beams (rafters) is via 20mm steel bolts and inserts Type D (Geka) 85mm dia. The connection between the main beams is via a pin joint using plates, screws, inserts and a profile IPE240. On the last truss a special support, at pin joint area, was created to house the two ridge beams

The BSH 68/147 pulins are connected to the main beams of truss through steel housings at 1m apart.

The covering panel is made of pine boards 2.5cm thick and 10cm wide. The boards have mortises on their sides to be linked. Over the boards installed insulation, corrugated sheet (for waterproofing) and finally Roman tiles (nailed).

The materials are laminated pine beams (AVEX) with metal connecting parts, specially fabricated steel profiles St37, or readymade (BILO). As connecting parts also used dowels, inserts, screws and corrugated nails quality III to DIN1052. To protect the wood (insects, fungi, humidity, UV) used the GORI system. The connection of the roof to the R.C pad used HILTI expansion bolts type HSA.

The balcony:
The balcony supports, besides its dead and live load, the protruding part of the third side of the roof (3 columns). The main structural system are anchored braced beams BSH 110/126. Anchoring is via a wooden beam BSH 68/147 connected to the stone wall through long bolts 8mm dia. using HILTI - HIT epoxy resin. At the edge rests a beam that supports the BSH 68/147 columns bearing the canopy roof. The balcony floor are boards same as on roof.

Flooring:
The floor was built on beams BSH 68/147 encased on a perimeter concrete pad lying on the recess created by the reduction in the thickness of masonry from the ground to the first floor. On the floor joists nailed long (~4m) pine boards 23mm thick 90mm wide.


The project has been completed and is in operation.
