ABSTRACT
In the case of overhaul and modernization of buildings, the external barrier must meet the requirements of applicable standards for thermal engineering of structures. The main forces acting on buildings and structures are static, dynamic and seismic forces. These forces reduce the service life of buildings and structures.
Any building must maintain the strength and stability of the structure at all times, as well as meet the requirements for its deformation. Otherwise, they can cause bending, twisting, subsidence, and other defects as a result of changes in the ground. Ensuring the resistance of buildings to the destructive effects of earthquakes in the construction of buildings made of energy-saving materials is a unique set of engineering measures.
Keywords: heating, fencing, insulation, basement, roofing, modernization and overhaul.
INTRODUCTION
In recent years, in order to radically improve the construction industry in our country, much attention is paid to strengthening its legal framework. Particular attention is paid to the use of new innovative technologies and solutions that meet the standards of developed countries.
Any building must maintain the strength and stability of the structure at all times, as well as meet the requirements for deformation. Otherwise, they can cause bending, twisting, subsidence, and other defects as a result of changes in the ground. Ensuring the resistance of buildings to the destructive effects of earthquakes in the construction of buildings made of energy-saving materials is a unique set of engineering measures
MAIN PART
The main forces acting on buildings and structures are static, dynamic and seismic forces. These forces lead to a decrease in the service life of buildings and structures. 'should be. Work on improving the thermal protection properties of barrier structures is carried out in the presence of an inspection report, which is based on the inspection of the condition of the barrier structures and their components, the technical condition of the house - and includes:
- Additional thermal insulation of walls:
- additional thermal insulation layer in the attic and basement;
- increase the thermal insulation of the corners;
- installation of sealing gaskets on windows and balcony doors;
- sealing of panel joints and fasteners.
Additional thermal insulation options are identified in the original survey of the house, the required level of thermal protection, the availability of materials and equipment for repair work on special technology on the basis of feasibility study of the selected option of additional thermal insulation, etc. should be determined according to the actual value of thermal conductivity of the structure found according to. Large prefabricated buildings should be provided with additional thermal insulation from the outside, with the most effective way to increase the thermal insulation of the walls is to use soft, semi-rigid slabs. The advantage of this species is; the ability of the heat sink to adhere tightly to the wall surface. The ends of the mineral wool plates are fixed with a sharpened rod. A metal mesh with anti-corrosion coating is installed on the surface of the heat storage plate. With its help, the heat-retaining plate is pressed against the wall. soft and semi-hard mineral wool boards with a thickness of 70-100 mm are used. A mixture of 1: 1: 4 (lime, cement, sand) is sprayed on the wall by torcreting. When the thermal insulation of the walls is increased by hard styrene and mineral wool boards on the outer surface, they are fixed to the concrete surface with emulsion-based PVA and epoxy resin glue. Renovation of the interior of single-layer expanded clay concrete walls is carried out as follows: an additional layer of 30-50 mm thick cast-in-place expanded clay concrete is formed or the inner surface of the panel is covered with 50 mm thick expanded clay concrete slabs and the slab surface is well rubbed with cement-sand mixture. The density of expanded clay concrete should not exceed 1200 kg / m3 for additional heat retention. Then a 1: 1: 5 (lime, cement, sand) lime-cement mixture is applied. The thickness of the additional layer of thermal insulation plaster is 30 mm. Soundproofing characteristics of barrier structures should be determined based on the results of instrumental inspections in accordance with GOST 15226-89. The most effective way to increase the sound insulation is to install flexible and thin slabs, the slabs can be installed on one side of the middle wall, or on both sides, leaving an air layer of at least 40-50 mm in the middle. Gypsum, fiberboard (DVP) and other boards can be used as slabs. When modernizing the apartment, it is recommended to use specially designed, light-layered middle walls to provide standard sound insulationIn the development of a project to modernize the housing stock, which is built of energy-saving materials, sun protection devices should be considered not only as a means of improving the sanitary and hygienic qualities, but also as a means of enhancing the architectural beauty of the building.
CONCLUSION
The main functional requirements for the protection of residential buildings from the sun in the dry hot climate of Uzbekistan are aimed at improving living conditions, which are:
1. Protection of the room from some kind of discomfort; {{1} } 2. Normal duration of insulation in the room;
3. Possibility of natural ventilation of the room;
4. The need for visual contact with the outside environment;
5. In natural lighting , normative conditions
