Heat and sound insulation unit with compensator and method of its laying (versions)

FIELD: construction.

SUBSTANCE: invention relates to flaky items used in construction for heat insulation of buildings and premises in it. The heat and sound insulation unit comprises filler webs laid one onto another, every of which comprises a corrugated sheet with corrugations of zigzag shape and a flat sheet connected to it. In each filler web, at least at one longitudinal side of the filler web, the flat sheet is arranged with a transverse size below the corrugated sheet by value of at least half of a pitch of a zigzag-shaped corrugation, thus producing a compensator from corrugations protruding beyond the flat sheet, capable of being compressed in transverse direction for gapless laying of the filler web into a building structure. A serrated line of corrugated sheet bend matches the edge of the flat sheet of the web. In the first version of block laying into a building structure the block is pressed with its longitudinal side with a compensator to the element of the building structure, and in this condition it is installed into the filled space of the building structure. The block compensator due to action of springing forces fills a gap produced between the block and the element of the building structure. In the second version, in case of layer-by-layer installation of block filler webs into a building structure, block filler webs that are adjacent along the height of the building structure are laid with a rotation relative to each other by 180°, and thus the compensator of the below block filler web is covered with a flat sheet of the filler web sheet. In the third version, in case of layer-by-layer installation of block filler webs into a building structure with equal longitudinal and transverse dimensions, block filler webs that are adjacent along the height of the building structure are laid with a rotation relative to each other by 90°, and thus gapless laying of the block is provided at all sides of the building structure.

EFFECT: invention provides for higher heat and sound insulation properties of blocks due to elimination of gaps between elements of building structures and fillers.

The technical field

The invention relates to layered products, used in construction for thermal insulation of buildings and premises in it.

The level of technology

There are a number of fibrous fillers[1], [2], [3], representing the rolls or slabs of mineral wool, fiberglass, providing the necessary heat and sound insulating characteristics, while the structure of such aggregates are easily stacked in the building structure.

However, the General lack of such fillers is that when working with them, as well as during operation there is a tendency to separate small particles of fiber and the possibility of their falling through the air into the body, which significantly reduces the environmental friendliness of this material.

Also known insulating construction elements consisting of the outer and intermediate layers that provide the necessary thermal insulation characteristics[4, 5, 6].

A common drawback of all these products is limited in their ability to reduce noise and limited to ensure backlash-free styling in the design.

The closest in technical essence of the present invention is a heat and sound insulating block containing stacked on each of the modules, each of which consists of garyowen the first sheet with corrugations zigzag shape and connected to a smooth sheet, the walls of the housing cover modules with end faces, the number of modules in the unit, as well as the flute height and angle of the faces of the corrugations for each module selected from a given value of the insulation [7]. The invention adopted for the prototype.

The disadvantage of this block is the inability ensure backlash-free styling placeholder in the building structure.

Well-known, conventional method of placing filler in the building structure, which includes layout, cutting caused by the markup and the subsequent laying in the construction design of the finished structural unit (foams) or reconstructiong (fibrous) placeholder [8, 9].

A common shortcoming of the conventional method of placing filler in building design is the difficulty of ensuring engineering standards precision cutting aggregates and the presence of additional technological operations for cutting and resizing blocks placeholder for violation of the norms of precision construction.

Known methods of filling foamed or samostanovlenie insulating materials cavities of building and other structures, which is based on the injection into closed cavities of different reagents, followed by polymerization and drying of the formed porous the first placeholder [10, 11].

A common disadvantage of these methods is the complexity and high cost of these technologies.

There is a method of mechanized laying loose aggregates with blowing devices [12].

The main disadvantage of this method is the seasonality of this method, as a binder for loose aggregates, for example ecowool is adhesive suspension on a water basis that it is not possible to use this method at low temperatures of the external environment.

The known method of installation of mineral products in the building structure, which is based on gapless installation placeholder for one of the line between rafters or beams, due to the fact that one part of the thickness of the mineral wool product in the manufacture subjected to creasing [13].

The disadvantage of this method is the fact that the fill emerging gaps due to inaccuracies of construction is possible only in one linear dimension. Also the downside is of different thickness and density of the aggregate in terms of building construction, which can degrade the effectiveness of sound insulation and heat insulation.

The closest analogue to the technical essence of the present invention, part of the fashion styling placeholder is the way, the realization of what has been created in the manufacture of wall structure, consisting in the installation of compressible and elastic part of the sheet of insulating filler in the return groove of another leaf [14].

The disadvantage of this method is that the clearance compensation due to inaccuracies of construction is possible only in one linear dimension, perpendicular to the direction of the groove and compressible part of the fill.

In the first embodiment of the process of laying the technical result is achieved by the fact that when laying unit in the building structure block press its longitudinal side with a compensator to the element of the building structure and in the condition set in the product space of the building structure, then the compensator block due to the action of forces springback fills the resulting gap between the block and the element of the building structure.

According to the second variant implementation of the method of installation of aggregate technical result is achieved by the fact that in layer-by-layer stacking of layers of unit in the building structure adjacent the height of the building structure cloths filler block stack rotated relative to each other by 180° and thus overlap the flat sheet fabric expansion joint filler of the underlying fabric of the filler block.

By the third variant implementation of the method of installation of aggregate technical result is achieved by the fact that in layer-by-layer stacking of layers of filler block construction design with equal about the Aulnay and transverse dimensions related to the height of the building structure cloths filler block stack rotated relative to each other by 90° and thereby provide a backlash-free laying of the block on all sides the building structure.

Since both heat and sound insulation block compensator, and variants of the method of its installation designed to improve the functional characteristics of structures, namely, heat and sound insulation, i.e. solve the same task in the application for the grant of a patent complied with the condition of unity of invention.
