On the second floor of the building there are: Trading pavilions for the sale of industrial goods, A monolithic reinforced concrete slab 150 mm thick is used as the floor. The slab solution provides for the installation of a monolithic slab with a thickness of 150 mm according to prof. flooring. The walls of the stairwells are made of aerated concrete 200 mm. The walls of the elevator shaft are made of monolithic reinforced concrete 150 mm thick. Filling between columns at el. above 0,000 to be made from sandwich panels along the frame. The project provides for a flat, combined insulated roof with an internal drain. The slope of the roof is accepted i=0,01. Roof insulation is made of rigid mineral wool boards Rocwool Roof Butts Optima - 100 mm. Exits to the roof are carried out from the staircase in the axes V-D and 7-8. Three staircases are designed in the building, which are located in stairwells with direct access to the outside and meet the requirements of SNiP 21-01-97 "Fire safety of buildings and structures". The width of the flights of stairs is 1500 mm. As a clean floor covering, ceramic tiles are provided in the bathrooms, and porcelain stoneware in the rest of the rooms. The internal partitions in the bathrooms are made of moisture-resistant plasterboard sheets lined with ceramic tiles to the full height. In other rooms, partitions are made of translucent structures on a metal frame. Ceiling in bathrooms. nodes - slatted metal, in commercial premises suspended ceilings of the "ARMSTRONG" type are provided.

Description of natural light solutions

The structure of the premises of the designed trading building includes premises for which (according to SanPiN 2.2.1/2.1.1.1278-03 with amendments and additions No. 1 SanPiN 2.2.1/2.1.1.2585-10) natural lighting is required, namely, room No. 106 - security room (dispatcher). For this room, according to SanPin, with the orientation of the light opening of this room to the SW, the standard value of KEO is eN = 0.7. For this room, it is not advisable to calculate the calculated KEO, since it has a continuous glazing of the outer wall.

Measures to protect premises from noise, vibration and other impacts

The soundproofing ability of structures between rooms (ceilings, partitions) was adopted by calculation and does not violate the requirements of SP 51.13330.2011 Table 2. Ensuring the normative sound pressure in the premises is ensured by the following measures: Enclosing structures are made of materials that do not have through pores. Seams in building structures are filled with mortar to the full thickness. Rational space-planning solutions in terms of acoustics. The main part of the engineering premises is located in the warehouse part of the building, where permanent residence of people is not expected. Engineering rooms are fenced off with sound-absorbing partitions and ceilings.

Description and justification of the adopted space planning decisions

The proposed building has one elevator. The walls of the elevator shaft shall be made of monolithic reinforced concrete with a thickness of 150 mm. Floor doors of elevator shafts fireproof REI 45. The project provides for a flat, combined insulated roll roof (covering: welded roll waterproofing ICO PAL "Villa Elast Solo Vent" - 4,8 mm) with an internal drain. The slope of the roof is accepted i=0,01. Roof insulation is made of semi-rigid mineral wool boards Rocwool Roof Butts. Exits to the roof are carried out from the staircase.

Fire safety

Classification of the building: Degree of fire resistance of the building -II; Class for constructive fire hazard of the building CO; Functional fire hazard class of the building F4.3, 5.2; The minimum fire resistance limits of the main load-bearing structures and the maximum limits for the spread of fire along them are taken from tables 1, 2*, 4*, 5 of SNIP 21-01-97*; Covering elements (flooring, trusses, beams, girders) must have a fire resistance rating of at least RE15. According to SNIP 21-01-97* p.5.18* it is allowed to use unprotected steel structures with the minimum required fire resistance R15 (RE15).; The bearing elements of the building - columns and ties, as well as beams of interfloor ceilings, must have a fire resistance rating of at least R 90. To raise the fire resistance limit to R 90, steel columns and ties, as well as beams of interfloor ceilings of the building, should be plastered using a special chain-link mesh, the thickness of the plaster layer is not less than 4 cm; Beams and stringers of evacuation stairs should be plastered according to a special chain-link mesh, the thickness of the plaster layer is at least 3 cm, to bring it to the fire resistance limit R-60. All materials used must have appropriate hygiene and fire certificates.
