Design Solutions

BASES

It was decided to make the foundation tape from monolithic reinforced concrete of class B25. Dimensions of foundation strip - refer to foundation drawings. Fill the tape on the base from ground crushed stone 200 mm .

The foundation is insulated from the outside with polystyrene foam (minimum compressive strength 0.35MPa) with a thickness of 100mm. A frame of 50x100mm boards impregnated with antiseptic solutions is installed on the ground part of the foundation walls, step 600mm.

The porch rests on columnar foundations made of asbestos cement pipes Ø150mm, concreted with concrete of class B25 .

All foundations shall be insulated from surface structures by waterproofing layer. The foundation is filled with sand and sealed with layers of at least 400 mm. All underground communications shall be carried out prior to final backfilling of the foundation.

When erecting the foundation, it is necessary to take into account the terrain of the section. The slope of the soil should be "from home."

EXTERIOR WALLS

The ground part of the bearing walls is built of gas-concrete blocks with a width of 292 mm. Walls are reinforced horizontally through 4 rows. The walls are insulated from the outside with 100 mm thick polystyrene foam (0.12 MPa min compression strength).

INTERIOR WALLS

Internal partitions are made of gypsum board sheets on metal frame 75mm. The internal walls of the boiler house are made of brick 120 mm. In the steamer, a frame of 50x50mm is installed on the walls, between which a stone wool of 50mm is laid, foil is laid over the wool and pressed by a distance rack of 20mm. A car of suitable for finishing paired wood is installed on top of the rack.

CROSSING POINTS

In the load-bearing walls, the design provides for the use of concrete in place railway bridges .

FLOORS AND CEILINGS

Wooden lags made of 50x50mm bar are laid on the concrete floor, with a pitch of 600mm. An insulation is laid between the lag - a 50 mm thick stone wool. As a flooring, a floorboard 30 mm thick laid over the lag is used.

In sanitary rooms, the working zone of the kitchen, as well as the entrance hall, polystyrene foam is laid on the concrete floor 30 mm (min. Compression strength 0.35 MPa). A 40 mm thick cement tie is arranged over the insulation. Ceramic tiles are laid over the brace.

The ceiling is built on load-bearing beams with a section of 75x200mm of a rafter system. Beams are supported by mauerlat 200x75mm. The metal frame PP66/27 is attached to the beams from below. The gaps between the beams are filled with 200mm stone cotton. Steam-proof film is attached between frame and bearing beams. Two layers of gypsum board sheets are attached to the frame. Along the perimeter of the attic space is a windproof slab of stone wool, 30mm thick and 1200mm wide. Detailed sections and subassemblies see drawings. Only grade 1 lumber is allowed in load-bearing wooden structures.

ROOF

The roof slope throughout the building is 17 °. The roof rests on wooden rafters with a section of 75x200mm and a pitch of 750mm. Rafters rely on mauerlat 200x75mm. Mauerlat is attached to the monolithic belt with the help of wedge anchors M14, installed with a pitch of 1000 mm. Rafters fasten to a mauerlat by means of metal fixing corners 100kh100kh80kh2mm. To better rest the rafters' legs on the mauerlat, a "tooth" with a depth of 75mm is made in the rafters. All wood parts should be isolated from stone surfaces.

A backing film is laid on the rafters over the entire area using 32x75mm remote racks (attach the rack using galvanized nails Ø3.0 l = 60mm). Ventilation in the skate shall be provided. On top of the racks, using galvanized screws Ø3.5 l = 100mm, an oriented chip plate OSB3 with a thickness of 18mm is attached. Lining roll material is laid over plates. Laying of lining layer is performed parallel to eaves, with overlapping 200 mm. A flexible tile is laid over the backing layer. When installing roofing, skates and cornices, follow the recommendations of manufacturers. On the parts of the rafters protruding beyond the dimensions of the outer walls, wind boxes from a strung board are made. Between the boards it is necessary to leave gaps of 15 mm for ventilation of the attic space .
