Typical redevelopment two-room apartment V type series houses II-49 includes a change in load-bearing structures. Therefore, before redevelopment, a preliminary professional survey is carried out, accompanied by engineering calculations. To connect the kitchen to the living room with an opening in the load-bearing wall, it is necessary to take measures to strengthen it with metal structures. In the course of combining the bathroom, attention should be paid to the high-quality waterproofing of the floor.

3-room apartment - Option 1

A typical redevelopment of a three-room apartment in a typical series of houses II-49 requires changes in the supporting structures. The preliminary stage before the start of redevelopment work is a professional survey, which must be accompanied by engineering calculations. In the course of creating an opening in the load-bearing wall between the kitchen and the living room, measures are being taken to strengthen the wall and lintel zones with metal structures. To properly combine the bathroom, you should remember about the high-quality waterproofing of the floor.

3-room apartment - Option 2

The second option, a typical redevelopment of a three-room apartment in the II-49 series of houses, also requires changes in the supporting structures. The preliminary stage before the start of redevelopment work is a professional survey, which includes engineering calculations. Creating an opening in the load-bearing wall between the kitchen and the living room requires measures to strengthen the wall and lintel zones with metal structures. During the unification of the bathroom, it is necessary to waterproof the floor.

3-room apartment - Option 3

A typical redevelopment of a three-room apartment in a typical series of houses II-49 with changes in the supporting structures needs a professional survey, accompanied by engineering calculations. The construction of an opening in the load-bearing wall between the kitchen and the living room requires measures to strengthen the wall and lintel zones with metal structures. To combine the toilet and bathroom, work is underway to waterproof the floor.

Multi-section residential buildings series II-49- were built in the cities of the central part of Russia from 1965 to 1985. This series has replaced the mass development of "five-story buildings". The first floor of the nine-story building of the II-49 series was most often made non-residential and set aside for the placement of infrastructure facilities. Therefore, several 12-story buildings were erected for the project, but this option was not widely used. Project II-49 includes two variations with the addition of the letter "p" or "d" at the end of the marking.

It should be noted that some II-49d houses were built from building materials that include phenol, a substance unsafe for human health. Today, buildings of this series are actively included in the lists of objects to be overhauled. More than 60% of houses II-49 were refurbished with the replacement of engineering networks, window blocks and additional insulation of wall outer panels. Unlike the II-49d series, the II-49p has an attic.

Design features of the series and finishing of facades II-49 (II-49p and II-49d)

External panels II-49 are made of three-layer claydite concrete grade M75, insulated with fiberboard or foam plastic, such walls had improved thermal insulation for that time. The internal walls are made of durable reinforced concrete panels (M200 grade concrete), and the interior partitions are made of gypsum concrete (8cm). Interfloor ceilings are made of reinforced concrete slabs (14 cm). The rigidity and strength of the entire structure of the II-49 building is ensured by floor panels and load-bearing intra-sectional walls, such flat panels were produced by vibro-rolling.

The foundation of II-49 is tape with plinth wall panels made of expanded clay concrete (M-100). For the location of engineering networks, a technical attic floor (if it is available in some modifications of the project) and a basement were used, the first floor is usually residential. Each section has only one elevator - a passenger one, which can cause difficulties in lifting goods to the upper floors.

Outside, the II-49 series was most often finished with small-sized tiles (glazed or ceramic), but some of the houses remained untiled. Interestingly, in this series, for the first time, the technology of finishing facades with tiles in the factory was used.

Features of apartment layouts II 49 (II 49p and II 49d)

The typical layout of sections provides for apartments with a number of rooms from one to four (sometimes 5-room apartments were also added). The design of houses II-49 is not very suitable for interior redevelopment due to the large number of cross-bearing wall panels. The positive point is that almost all the rooms in the apartments of this series are not adjacent. The area of ​​living quarters is increased due to large balconies, which are in all apartments, except for "odnushki".

Series II-49 brought newness to standard construction, extraordinary techniques were used in the design and decoration. The houses were designed in the 70s, today these buildings are not subject to demolition and will not be subject to it in the foreseeable future. A large number of buildings in this series have been reconstructed.

New technological solutions have affected, first of all, wall cladding and joint processing:

• small granular tiles were applied on the panels;
• open joints were treated with water-punching tape.

The II-49 series replaced the obsolete K-7 series. There are two modifications in the series:

• II-49d;
• II-49p.

In modification II-49p, some houses contain phenol insulation, which pollutes the air, the same buildings, but in smaller quantities, are in modification II-49d. The difference between the two options is small: the II-49p model is additionally equipped with an attic. Houses of this series were built in Cheryomushki, Orekhovo, Yasenevo, etc. There are several buildings in the cities near Moscow, and several buildings are also present in the Crimea and Togliatti.
