Space-planning solution of the building

The theme of the work is "Two-story residential building of small-sized elements"

The construction of this residential building is provided in the city of Grodno, Republic of Belarus. In plan, the building has a rectangular shape with windows and balconies. The width of the building in the coordination axes 1-6 is 13.79 m; length in axes A-E is 19.3 m; taking into account the interlock, the length of the building in axes A-L is 38.6 m

The type of residential building is blocked. The building is two-story with a floor height of 3 m.

In the plan of each of the blocked buildings, eight room apartment of improved layout is designed with a total area of ​ ​ 208.22 m ^ 2

Structural system - wall, structural scheme of the building - with longitudinal bearing walls. Buildings are locked along axis E.

The rooms are located in two levels with an internal staircase. The building has 2 separate entrances for each apartment. The apartment has 6 living rooms .

On the ground floor are designed: living room, office, living room, kitchen room, combined bathroom, hall, tambour, garage.

On the second floor: 3 bedrooms, guest room, winter garden, hall, 3 separate bathrooms.

Walls and Partitions

External walls of the building are executed from a silicate brick ρ=1600 by kg/m3 height δ=0.12 in m. The internal surface of walls is plastered by a layer of limy and sand solution 20 mm thick. Interlayer space is filled with insulation by polystyrene foam a = 25 kg/m3 thickness δ = 140 mm. The thickness of the outer walls is selected in accordance with the thermal design (see the corresponding paragraph of the explanatory note) and is 510 mm without taking into account the plaster layer. Thickness of internal bearing walls 380 and (1.5 elements) of partitions - 120 mm (0.5 elements). Partitions are lined with gypsum board δ = 10 mm

Overlappings

Overlappings are executed from melkorazmerny elements: wooden beams of 200 mm and gipsobetonny plates of the brand P1 370х500х200 (h). Wooden beams rest on external bearing and internal walls for 150 mm. During installation, wooden floor beams are laid on walls with a pitch of 470 mm. The holes for passing plumbing pipes and ventilation ducts are interplate (see the floor plan in the graphic part).

Ladders

For inter-storey communication in the designed building, there is a two-marching small-scale wooden staircase on the kosuras. The staircase is designed with a wooden fence. The width of the landing is 1000 mm, the width of the flight of stairs is 1100 mm. For fire safety purposes, 220 mm clearance is provided between the marches for free passage of the fire hose. Calculation of structural elements of the ladder is given in the corresponding paragraph of the explanatory note.

Roof

In accordance with the task, the roof is designed rolling wooden. The sent rafter system consists: from rafters 75kh200mm, the furring made of bars 50х50 with a step of 500 mm, a run on racks 100kh100mm, it is resistant 100kh100mm, the mauerlat of 100х100 mm.

As the roofing material, the Ruflex coating is similar, and in some respects superior to the Katepal coating. The roofing elements are fastened using liquid nails to the screen. The grid boards are fixed with nails to rafters. To prevent mechanical deformations of the roof and maintain the standard humidity of the wooden roof elements, a layer of moisture-resistant plywood 20 mm thick is laid between the roof and the grating.

Rafters are interconnected by means of paired linings and nails. For more reliable fastening of rafters with walls, twist and "yersh" are used, which is laid in the suture of masonry. Waterproofing is used to adhere to materials - 2 layers of toll.

Sediments and meltwater are drained through an organized external watershed. A visor is designed above the entrance.
