Technical field

The utility model relates to the field of construction and can be used in the construction of interfaces, for example, window boxes, doors, showcases, stained-glass windows with the outer walls of the building, erected in areas with low design temperatures.

Currently, the construction of residential buildings uses window and door blocks of various designs, the choice of which is guided by the regulatory requirements for fencing boxes of openings of external walls, regulated, for example, SNiP II - 3 -79 (table 1 b, appendix 6). According to these requirements the slope temperature of window and door openings with the calculated parameters of internal air (tg 20 C, W 55%) must not be lower than the temperature of the dew point of indoor air. In accordance with these requirements, in areas with low design temperatures, the junction box of the opening elements of the building fencing with its outer wall is made with warming the internal slopes of the openings in order to avoid the formation of cold bridges (thermal bridges), leading to the formation of condensation on the inner surfaces of the light openings.

Prior art

It is known, for example, the framing of a window opening (A.S. USSR No. 1178892, class E 06 B 1/32, 1982), according to which it consists of a mounting concrete frame with slopes around the perimeter of the light opening, a box, a thermal liner and an effective heater,

placed around the perimeter of the box, transparent filling of two or more layers of glass. Moreover, the thermal liner is made developed in the plane of the window and recessed in the body of the concrete frame.

serial production due to the lack of grooves for the thermal liner in them, and the re-equipment of the production line of typical wall panels to a new one will entail significant economic losses. In addition, effective heaters are quite expensive.

Therefore, the described framing of the window opening is not economical and requires additional labor.

Brief Description of the Drawings

In the future, the utility model is illustrated by drawings made for the interface box, for example, a window unit with its outer wall, represented by a three-layer wall panel, on which:

in FIG. 1 shows a facade of a wall panel with a light opening with a box of a window unit installed in it;

in FIG. 2 is a section AA in FIG. 1;

on figs - temperature distribution in the interface node of the window unit with the additional element and the wall panel, section AA in fig. 1;

The inventive interface includes a wall panel 1, a light opening 2, made with internal 3 and external 4 slopes along the contour of the light opening 2, a box 5, for example, a window opening. On three sides of the light opening 2, in the slopes 4, a thermal liner 6 is installed, which increases the coefficient

resistance to thermal transmission. The thermal insert 6 is tightly coupled simultaneously with the slope 4 of the light opening 2 and the box 5 of the window unit. In this case, the mounting axis of the box 5 is offset in the plane of the panel by the width (A) of the thermal insert 6 towards the inside of the wall panel. The width (A) of the thermal insert 6 depends on the panel design and climatic conditions in which the building is erected in accordance with the regulatory thermal requirements for windows according to SNiP P -3-79 (table 16, appendix 6) and is determined by the expression

A J (Ku + M + Kb),

where Ku is the function of the calculated data of the climatic zone according to SNiP;

M - function characteristics of the materials of the wall panel;

Kb is a design function of the window unit. As calculations showed, the width (A) of the thermal liner 6 can be in the range of O - 100 mm for different climatic zones. The height (Bi) of the thermal insert 6 is determined by the width of the supporting part of the light opening (2) and the outer dimensions (B) of the box 5 of the window unit, and can be from O to 100 mm. In addition, the thermal insert 6 is firmly connected to the box 5 of the window unit, for example, by gluing, either with the fasteners of the screws, or by screwing it with self-tapping screws, or in any other way. The thermal insert 6 in the plan can be made in the form of a polygon, for example, a square, or a rectangle, or a trapezoid, or a truncated cylinder, or a segment exclusively in accordance with aesthetic requirements,

presented to the product. To comply with the aesthetic properties of the window unit as a whole, the thermal insert 6 may have a bevel at an angle a equal to 0-90 degrees. The bevel is a constructive continuation of the external slope of the panel and the angle of its execution depends on the angle & external slope of the panel. An additional element is made of material.

Industrial applicability

In this case, all calculations were carried out in the climatic conditions of the city of Krasnoyarsk, namely: in the case of the use of three-layer wall panels and window blocks made in accordance with GOST 24700-99 “Wooden window blocks with double-glazed windows. Technical conditions

Regulatory heat engineering requirements for windows are regulated by SNiP P-3-79 (table 16, appendix 6). According to these requirements, the reduced heat transfer resistance of window blocks for the conditions of the city of Krasnoyarsk for residential buildings (estimated winter outdoor temperature IH -40 ° C, 6341 GSOP) should be at least 0.62 m ° C / W. At the same time, the temperature of the inner surface of the structural elements of the window blocks should not be lower than 3 ° С at the calculated outdoor temperature. The slope temperature of the window openings with the calculated parameters of the internal air (IB 20 С, W 55%) should not be lower than the temperature of the dew point of the indoor air tp 10.7 ° С.

The heat engineering calculation was performed for a wooden window block with a double-glazed window produced by the West Siberian regional branch of Branco AG, taking into account the closure in the wall panel manufactured by CJSC

"The company" Kultbytstroy taking into account the heat engineering requirements.

The window unit with a box thickness of 78 mm with glazing by a double-chamber double-glazed window SPD 4Mi-84Mi-8Ar-K4. Double-glazed window - with aluminum spacers. The window unit is installed in the wall panel of large-panel house-building series 111-97 with a thickness of 350 mm from expanded clay concrete with a density of 1500 kg / m with an internal thermal insulation layer of foam plastic with a thickness of 110 mm. The cross section of the window unit is shown in FIG. 2.

The calculation was made for the interface unit of the window unit and the vertical slope. A wooden thermal liner 50 mm wide is installed along the contour of the window opening, to which the window block adjoins. To close the gap between the window block and the panel, foam is used.

The result of this calculation is to determine the minimum temperature on the inner surface of the slopes adjacent to the box of the window unit, which should not be lower than the dew point equal to 10.7 ° C.

Thermotechnical calculations were performed using the WINDOW software package (PC) as part of WINDOW 4.1 and THERM 2.0 (Windows and Deylighting Group Building Technologies Program Energy and Environment Division Lawrence Berkeley Laboratory Berkeley, CA 94720 USA), Certificate ROSS RU. SP 11.H00016. M., 2000.
