Introduction

The course project considered a twelve-story monolithic residential building, with a technical floor, an unexploited roof, and a basement. The house is intended for construction in Suzdal.

This course design is based on the following requirements:

SP 54.13330.2016 "Residential apartment buildings" SP 50.13330.2012 "Thermal protection of buildings," SP 20.13330.2016 "Loads and impacts," SP 21103.2003 "Design and installation of electrical installations of residential and public buildings"

Design Input

Multi-storey two-section residential building (storey - 13 floors, including technical floor), made in accordance with the monolithic structural scheme of construction. Construction area - Suzdal.

Space planning solutions

The designed residential building consists of 2 end sections with 13 floors. On the ground floor there are residential premises with the possibility of further removal from the housing stock and use for offices. Typical floors of the section have the following set of apartments: 3-1-1-1-3. Some apartments have glazed unheated loggia.

The relative elevation of 0.000 is the elevation of the clean floor of the floor slab of the technical floor equal to + 0.750, relative to the ground level. The height of the building floor is 3.0 m, the height of the basement is 2.7 m. The maximum elevation of the top of the building is 43.4 m.

On the ground floor of each section there is an entrance group, which includes a lobby with a place to accommodate mailboxes. At the entrances, a double tambour is arranged with the installation of metal doors with a doorphone. The entrances to the building are equipped with a metal ramp and swing doors to allow the entry of disabled people on wheelchairs. On the ground floor, a garbage collection chamber is designed with the possibility of removing the container to the sidewalk. The entrance to the residential section is represented as a volumetric decorative element in the form of a polycarbonate roof, which acts as a visor above the porch.

Lifting to 213 floors is carried out by two elevators: cargo and passenger (load capacity 630 kg) and passenger (load capacity 400 kg). For evacuation in case of fire, a non-smoke staircase of type H1 is provided.

Heated basement with exit from stairwell space is designed under the whole hull. The basement has a through passage along the entire building. The building has a technical floor with a height of 3 m, designed to accommodate communication systems, engineering equipment, machine rooms and elevators. Passage to the technical floor, as well as access to the non-operated roof, is carried out through the space of the staircase .

The building has a two-march staircase made of monolithic reinforced concrete, connecting 13 above-ground floors, including technical; basement; exit to non-operated roof. The house is equipped with hot and cold water supply, sewage, heating, natural exhaust ventilation, electricity, waste water with a box diameter of 430 mm. There is low-current equipment - telephone communication, television and Internet networks.

Architectural and structural solutions

The building is 13 storeys made in full assembly version. The dimensions in the plan are 26.4 x 17.4 m, 44.1 m high from the planning elevation of the ground. According to its parameters, it belongs to the type of buildings - sectional.

Spatial rigidity is ensured by the joint operation of the load-bearing walls and the monolithic reinforced concrete slab disk.

The stability of the building is provided by transverse and longitudinal monolithic structures of the internal walls, which form a single rigid spatial system with a monolithic reinforced concrete floor.

Base

The monolithic reinforced concrete slab has parameters: width - 1000 mm for external bearing walls, height - 300 mm. Depth of foundation foot laying is 3.0 m from the level of clean floor of the first floor.

Waterproofing is arranged to protect against groundwater. The vertical layer of waterproofing is carried out by double coating of the walls adjacent to the ground with bitumen mastic, horizontal waterproofing is represented by the primer and subsequent sheets of waterproofing "EPP Technoelast."

Walls

Exterior Wall Design:

a) Monolithic bearing railway walls: a monolithic wall with a thickness of 200 mm, an effective insulation in the form of extruded foam polystyrene "Foam XPS" with a thickness of 100 mm, as well as a facing layer made of silicate hollow brick with elastic bonds in the form of facade dowels.

b) Embedded non-bearing walls: full ceramic brick with standard dimensions of 250 x 120 x 65 mm, effective insulation in the form of extruded foam polystyrene "XPS Foam" 100 mm thick and a facing layer of silicate hollow brick with elastic bonds in the form of facade dowels.

Interior wall design:

The inner walls are represented by monolithic reinforced concrete 200 mm thick.

Partitions:

The interior of the building is divided into separate spaces using partitions. Partitions are made of silicate hollow brick with standard dimensions 250 x 120 x 65 mm; inter-apartment partitions are structures made of monolithic reinforced concrete with a thickness of 200 mm, which corresponds to the necessary sound insulation indicators - 52 dB.

Overlappings

The load-bearing element of the floor slab of a typical floor is an interdigitated monolithic slab slab 200 mm thick, for an inter-storey platform - monolithic slabs 200 mm thick.

Ladders

To enter/exit the building and communicate between floors in the house there are stairs made of monolithic reinforced concrete, having a slope of 1:2 and standard sizes of steps 300 x 150 mm. The internal staircase has 2 flights and provides movement between the 13 floors of the building (including the technical one), as well as the basement and the non-operational roof. The building is equipped with a non-smoke staircase type H1 for safe evacuation of people in case of fire.

Roof and covering

In plan, the roof of the entire building has a flat inclined shape. The main load-bearing element of the roof is a monolithic reinforced concrete slab disk 200 mm thick, resting on the underlying vertical load-bearing monolithic reinforced concrete walls 200 mm thick. All of the above subassemblies provide the structural capacity and spatial rigidity of the roof structure.

To ensure the removal of water, a so-called "slope" is provided, created by a slope-forming layer of expanded clay gravel having a slope index of i = 0.05.

Due to the formed slope, the water caught on the roof is removed by rolling and entering the water intake funnel, which, in turn, leads to the storm sewer. Thus, precipitation is removed from the roof surface. Also, the roof cover is formed by several layers of roll waterproofing "EPP Technoelast," a bitumen primer.

Drain

Watershed - internal organized; its design includes: gutters, plugs, gutters, bypass elbows, branches.

Thermoinserts

Thermowells "Foam" are located in the disk of the interstage overlap to prevent the formation of cold bridges. Have a size of 300x150x200 mm; are made of extruded polystyrene foam located in heat-insulating layer, which makes it possible to arrange these elements in overlapping disk.

Windows and doors

As window filling, KBE PVC windows of 1.2 x 0.9 m dimensions are used; 2.4 x 1.5 m; 1.4 x 1.5 m; 1.6 x 1.5 m; 0.8 x 1.5.

Entrance doors - 1.4 x 2.1 m (into the space of the elevator assembly), 0.9 x 2.1 m (into the space of the staircase );

Inter-room, balcony doors, as well as entrance doors to apartments - 0.9 x 2.1 m, 0.7 x 2.1 m. Doors to the space of individual rooms - 1.2 x 2.1 m; 1.5 x 2.1 m.

Attach window and door boxes with self-cutting screws. Gaps between window and door boxes and wall structure along the entire perimeter are filled with polyurethane foam sealant. Windowsill casts are made of galvanized steel with an institution for lining slopes. Silicone sealant for external works is used to seal the areas of attachment of protective aprons to walls.

Room Finishes

Internal finishing is solved taking into account operational features. The inner surface of all the external walls of the building and the surface of the partitions are plastered on a grid, followed by a trellis, over which wallpaper is glued in residential rooms, and ceramic tiles are laid in the kitchen, bathrooms and boiler room. The floors of the standard floor are made of "Kronostar" laminate, and the floors in the bathrooms, kitchen-dining rooms are made of ceramic tiles. The floors of the basement, first and technical floors are also made of ceramic tiles.

Engineering equipment

The building considered in this course project is equipped with electricity, connected to the city sewage system, heated from the city network.
