RU53337U1 - RECOVERY MULTI-STOREY RESIDENTIAL BUILDING - Google Patents

Abstract

The utility model relates to the field of construction and relates to the structural implementation of a multi-story residential building during its reconstruction. The objective of the utility model is to create such a reconstructed multi-story residential building, which provides a higher superstructure without resettling residents and the need for redevelopment of the apartments of the base building and the restructuring of its staircase and elevator node. The reconstructed building consists of a base 1-2 section building with a height of no more than 14 floors with external and internal walls, ceilings, a staircase and elevator unit, a technical room, a superstructure and an extension with a floor of no less than a basic building with a superstructure. The extensions are located at the ends of the base building and each of the extensions has its own staircase and elevator unit with a non-smokeable staircase, which is connected on all floors of the superstructure by an extra-apartment corridor with the entrances to the apartments adjacent to the annex section of the base building, while the width of the non-apartment corridor is at least 1, 4 m, and the distance along it from the exit from the apartment to the entrance to the staircase of the non-smoke type does not exceed 25 m.

Description

The utility model relates to the field of construction and relates to the structural implementation of the reconstructed multi-story residential building.

Closest to the proposed utility model is a reconstructed multi-storey residential building containing a basic residential building with an attic, external and internal walls and ceilings, forming apartments and non-apartment corridors, an extension providing for the expansion of the building in plan, the number of storeys not lower than the base building, superstructure containing additional floors in the dimensions of the entire built-up area, and staircase elevators installed in the base building and in its superstructure and extension; a sedimentary seam is made between the base building and the extension (see patent for invention of the Russian Federation No. 2112850, E 04 G 23/00, 06/10/1998)

The disadvantages of the above solutions include:

- the need for a complete resettlement of residents of the base building and its internal redevelopment, which also includes the reconstruction of the staircase and elevator unit with the installation of a non-smokeable staircase;

- the impossibility of using the additionally obtained total area of housing for the construction of compact municipal apartments (the significant expansion of the building does not provide the expansion of the light front necessary for residential premises);

- the device structurally-shrinkable seam in the indoor premises.

As a consequence of the above, this solution cannot be considered the most economical, and its application is limited to the reconstruction of houses with full resettlement and the construction of apartments for “commercial” settlement.

The objective of the proposed utility model is the creation of such a residential building, which provides a higher superstructure without resettling residents and the need for redevelopment of the apartments of the base building and the restructuring of its staircase and elevator node.

To obtain such a technical result in the proposed reconstructed multi-storey residential building containing a base building with an attic, external and internal walls and ceilings, a multi-storey superstructure, an extension with a floor of at least the floor of the base building and staircase elevators, the extension adjoins at least one end the base building when performing it with single-section and number of storeys no more than 14 floors or to both ends of the base building when performing it

two-section of the same number of floors, with a staircase and elevator unit installed in each of the outbuildings with a non-smokeable staircase, which is connected on all floors of the superstructure by an extra-apartment corridor with entrances to the apartments adjacent to the annex of the base building section, while the width of the non-apartment corridor is at least 1, 4 m, and the distance along it from the exit from the apartment to the entrance to the staircase of the non-smoke type does not exceed 25 m.

Distinctive features of the proposed solution from the known one are that the extension adjoins at least one end of the base building when it is single-section and no more than 14 floors high or to both ends of the base building when it is two-section the same number of floors, with a staircase and elevator unit installed in each of the extensions with the implementation of a staircase of a non-smoke type, which is not connected to the non-apartment corridor with the entrances to the apartments of the section of the base anija, wherein vnekvartirnogo corridor width is not less than 1.4 m, and the distance of it from the outlet of the flat before entering the ladder type nezadymlyaemogo does not exceed 25 m.

Figure 1 schematically shows a reconstructed multi-story building, a vertical section.

Figure 2 is the same, in plan at the floor marks of the base building.

Figure 3; 4 - the same, in plan at the floor marks of the superstructure.

The reconstructed multi-story residential building consists of base building 1, superstructure 2 and extension 3.

The base building 1 can be single-section or two-section (the second section is shown in Fig. 2 and Figs. 3–4 by a dotted line and has a mirror image of the first section) with a height of no more than 14 floors with external and internal walls, ceilings, staircase-elevator unit 4 and an attic room 5.

Superstructure 2 is made in the form of several additional floors, which are supported independently from the base building by pylons 6 and pile grillage. The staircase-elevator unit 4 is extended to the height of the superstructure.

Annex 3 is adjacent to one or both ends of the base building 1, while the number of storeys of the extension is not less than the number of storeys of the base building with the superstructure. A one-section base building can have at least an extension from one of the ends, a two-section base building has an extension from both ends.

Each of the extensions 3 has a staircase and elevator unit 7 with a staircase of a non-smoke type.

When reconstructing the base building to a height of more than 17 floors, access to the stairwell (type N-1) from each floor of the extension and superstructure is carried out through an open, smoke-free passage 8; when superstructure up to a height of 17 floors can be used type

non-smokable stairs with internal air supply in case of fire (type N-2, N-3) with access to the intermediate vestibule lock 9.

The stairs 7 carry out the evacuation of people from annex 3 and superstructure 2, for which an extra-apartment corridor 10, connecting the staircase 7 with the entrances to the apartments adjacent to the extension of the base building section, is floor-mounted in the superstructure 2, while the width of the non-apartment corridor must be at least 1.4 m, and the distance along it from the exit from the apartment to the entrance to the staircase 7 of the non-smoke type does not exceed 25 m.

The evacuation of people from the base building 1 is carried out on the stairs of the staircase and elevator unit 4, which is extended to the height of the superstructure, however this staircase is not evacuation and therefore must be isolated from passage 8, and the openings connecting them must have doors 11 with a vestibule, and doors to elevator shafts 12 must be fireproof.

The reconstructed multi-storey building does not require resettlement and redevelopment of the apartments of the base building and the restructuring of its staircase and elevator unit.

The types and composition of the extension and superstructure apartments are not limited, in addition, these parts of the building can be completely isolated from the base building. In addition, any structural and shrink seams pass only in non-apartment premises.
