Description

Field of technology

The utility model relates to the field of construction, specifically to devices that are installed in attic openings, and can be used to isolate residential and non-residential premises from penetration and (or) losses: cold, heat, noise, moisture, dust and odors during construction and repairs .

State of the art

Today, various devices are known from the prior art for isolating attic openings from residential and non-residential premises.

Thus, an insulated upper box (see https://lerovmerlin.ru/product/uteplvavushchiv-verhniv-korob-lxw-ru-60x120-sm-83791488/) made of wood and an insulated hatch to the attic (see https ://newsaler.ru/rooflng/uteplennvj-luk-na-cerdak-svoimi-rukami-opisanie-treh-osnovnyh-konstrukcij.html) made of plywood and metal, in which mineral wool, polystyrene foam and foam rubber are used as insulation.

These solutions are labor-intensive to manufacture and install, and the use of wood in the design of the device involves its processing to protect it from moisture. In addition, these solutions contain rather heavy lids in their design, which require significant effort to open/close them.

From the patent for utility model of the Russian Federation No. 183984 (published on October 11, 2018, MPK E06B 5/10, E06B 5/16), which was chosen as the prototype of this utility model, a hatch for buildings and structures is known, which is a box mounted on an opening and having an upper wall and side walls, each wall is made flexible, characterized in that each wall is made of a multilayer material formed from two layers of fiberglass material, between which a heat-insulating layer is placed, along the perimeter of the box there is a flexible strip that acts as a frame for fastening to a solid surface along the perimeter of the opening, the strip is permanently connected to the lower edges of the side walls by means of a sewing connecting seam, the upper wall with one edge is permanently connected to the upper edge of the corresponding side wall, and the other edges of the upper wall are connected to the edges of the side walls by means of a detachable connection, providing During operation, the possibility of tilting the top wall.

The disadvantage of this solution is the use of two layers of fiberglass with a polymer coating, between which there is a layer of thermal insulation material in the form of mineral wool. Fiberglass is susceptible to edge fraying - even if the fibers are sealed in the edge, they come off easily. Mineral wool, in turn, needs additional treatment with water-repellent compounds and vapor barrier, as it absorbs moisture well. The level of water absorption of mineral wool is 15%. When moisture gets in, the thermal insulation and sound insulation abilities of the material deteriorate. Vata has an “airy” structure, so it shrinks over time and its properties deteriorate. The listed disadvantages directly affect the performance characteristics of the product.

This utility model is aimed at solving the problem (technical problem) of eliminating the shortcomings of known analogues and the prototype, and is also aimed at solving the problem of increasing thermal insulation, sound insulation and vapor barrier characteristics.

Disclosure of the essence of the utility model

The technical result provided by the essential features of the utility model is to increase the thermal insulation, sound insulation and vapor barrier characteristics of the thermal cover used to isolate the attic opening from residential and non-residential premises.

Achieving a technical result is ensured by a thermal cover (hereinafter referred to as a thermal cover, device, technical solution), which is a box installed on top of the attic staircase box and having an upper wall and side walls, each wall is made flexible, the upper wall is permanently connected with one edge the upper edge of the corresponding side wall, and the other edges of the upper wall are connected to the edges of the side walls by means of a detachable connection, providing during operation the possibility of folding the upper wall, characterized in that each wall is made of a multilayer material formed from two layers of smooth polyethylene, between which there is a a layer of bubble wrap, and a layer of aluminum foil.

Brief description of drawings

The claimed technical solution is illustrated by the image:

Implementation of a utility model

The claimed technical solution is illustrated by the drawing, where in Fig. A general view of the thermal cover is presented.

The thermal cover is essentially a sewn product in the form of a frameless box, which is placed on top of the attic staircase box, protecting the flight of stairs from dust and dirt from the attic side. In this case, the upper wall (1) of the thermal cover is made with the possibility of opening to operate the hatch for its intended purpose.

The thermal cover is attached to the opening in any available way, allowing it to be secured to the appropriate material of the opening (stapler, self-tapping screw, glue, etc.). During operation of the thermal cover, the user opens the upper wall (1) using a zipper (2) and bends it upward, after which he enters another room or part of the room (structure).

The upper wall (1) of the box is basically rectangular in shape. The detachable connection of the edges of the top wall (1) with the edges of the side walls (3) is made along the edges of the box. One of the sides of the upper wall (1) can be made elongated in the form of a tongue with rounded edges, which bends onto one of the side walls (3), connecting to it with a zipper (2).

To further improve the performance characteristics of the device, the box is stitched around the perimeter with textile material using a sewing seam (4).

The walls of the box are made of flexible multilayer material containing two layers of smooth polyethylene, between which there is a layer of air bubble film, and a layer of aluminum foil. The material consists of layers of dense air bubble film 4 mm thick. Between the layers of smooth polyethylene, closed cavities are formed containing dry air, which is the best heat insulator. The material creates the so-called “thermos effect”, while the room is reliably protected from the penetration of cold from the outside, and the heat remains inside.

A distinctive feature of these heat-insulating materials is their high resistance to heat transfer and, as a consequence, high heat-insulating properties. In addition to thermal insulation, these materials also provide sound insulation and vapor barrier.

The high thermal conductivity of aluminum allows heat to be evenly distributed over the surface and retains infrared radiation, returning the heat flow back to its source. Aluminum retains its reflective properties even when wet.

At the same time, these materials are resistant to mold, insects and rodents, and can also take any shape, which makes installation and assembly easier.

The claimed technical solution and the material for its manufacture provide the possibility of simple installation.
