Description

Technical field

The technical solution relates to the field of construction, namely the design of the window unit, which is a component of the wall or roof structure and is intended for communication of indoor spaces with the environment, natural lighting of the spaces, their ventilation and protection against atmospheric phenomena and noise.

BACKGROUND OF THE INVENTION

According to GOST 23166-99 “Window units. General technical specifications': The window unit is a translucent structure consisting of mounting units - frame (lining, lining profile), sash parts and built-in ventilation systems and, if necessary, several additional elements: blinds, blinds, etc ..

From publicly available sources:

- GOST 30674-99 “Window units with polyvinyl chloride profiles. Technical specifications';

- “Design of modern window systems for civilian buildings.” I.V. Boriskina, A.A. Plotnikov, A.V. Zakharov. Manual from MISI MGSU. Publishing Committee. (Fig. 2 2.3.1. (Design of PVC window profiles. Combination of frame and leaf). Designs of modern window units comprising a frame and a window panel with separating frames between adjacent glass panes are known.

The frame is firmly secured to the walls of the window or door opening and carries all the other components, and serves specifically to hang the wings. The sash (part of the sash, sash) is a frame structure, the window panel casing (translucent panel) connected to the frame (lining), generally by way of a hinged or plugged connection, which is attached to the frame with parts mounted on a special slot on the sash, fulfill the window opening function. A window panel is a bulky object consisting of two or more glass panes connected around the perimeter by separating frames and a seal which forms sealed chambers filled with dehydrated air or other gas. The window panel is fixed to the sash with the help of a pane holder, which also contributes to tightly attaching the window panel to the gasket in the crossbar (sash profile flange for installing the gasket and overlapping gaps on the ledge) to prevent the sash from leaking.

The main drawbacks of the well-known designs of modern window units include:

1. Poor light transmission (key window function) due to the relatively large overall dimensions of the window profiles.

2. Poor heat retention due to limited choice of window filler used.

The thickness of the window filler is one of the factors that has a significant effect on the thermal transmittance of the window. The window panel consists of glass panes and spaces between the glass panes, which serve as the main thermal insulators of the window panes and are filled with special gases (mostly dehydrated air, occasionally argon, rarely cryptone). The larger the heat-insulating space, the higher the thermal conservation of the window unit, but only to the level where gas flow begins in such a space. The ideal thickness of this space is considered 20 mm. In other words, window fillings with a thickness of 4 + 20 + 4 + 20 + 4 = 52 mm can be considered the best. The thickness of the window panels is always smaller than the thickness of the sash as it is secured by the holder from the inside, while it is pressed against the edge of the profile on the other side. In today's window structures, window panels up to 41 mm thick are used, but installing thicker window panels requires even larger leaf profiles, which is economically disadvantageous.

The relatively high cost of the entire structure, due to the large number of elements used, the large number of assembly operations, the high specific weight of the profiled elements in the price of the materials used in the structure. The specific weight of the profiled elements, in particular PVC profiles, reinforcement and sealing, constitutes about 50% of the cost of materials in production, the window panel is about 20% and the paneling about 30%.

Next, due to the use of the main parts and used as a prototype, it is known ("About the development of new window unit designs. SA Kelyin." Translucent structures "Magazine No. 1-2, 2009) Window unit design consisting of frame and window panel with separating a frame between adjacent glass panes, made with a profile having a cutout for the seals needed to secure the window panel in the frame and to open the window.

The reasons for not achieving the results that are specified below may be, for example:

1. the need to use glass panes of various dimensions in the window panel, one of such larger glass panels (from the inside) serving to cover the inner ledge (gaps between the frame and the window panel); the use of safe, triplex and generally expensive glass, the edges of which must be perfectly cleaned to cover the gap;

2. the need to treat the circumference of the opaque window panes in order to hide adhesive traces and filler parts (separating frames with fillers);

3. use of a specific foil glued to the glass pane to ensure the required level of air permeability of the window panel.

It should further be noted that the design of a window panel in which the glass pane overlaps the frame may result in the entire structure being perceived inappropriately.

The essence of the technical solution

The aim we want to achieve with the claimed utility model is to modernize existing window unit designs and improve their main functional characteristics. The main technical objective that can be achieved as a result of the implementation of the claimed utility model consists in reducing the manufacturing cost of the window unit design while maintaining the traditional external appearance and improving thermal insulation, while ensuring the necessary degree of air permeability.

This technical objective can be achieved by the known window unit consisting of a frame, a window panel with a separating frame between adjacent glass panes formed of a profile with a cutout for the panels necessary to secure the window panel in the frame, in addition consisting of a strip placed around the perimeter glass and covering the inner ledge, the strip has a gasket installed in the cut-out, while glass panes of the same size are used for the window panel.

The use of a standard window panel with glass panes of the same size and type in a window unit makes it possible to reduce the manufacturing cost of the final product compared to the prototype, since it is possible to integrate the claimed structures into the standard window panel manufacturing process and ensure the required work efficiency. The use of a strip (cover strip) to cover the inner ledge allows to cover the profile of the separating frame with the gasket and filler, as well as the use of a standard gasket used in conventional structures between the window opening (sash) and the fixed window (frame). the air permeability level of the window unit and further to ensure continuity in the external appearance of the product as compared to the window sash designs that are common today. In the design process, the standard gasket, which should be mounted on a special location, has a mushroom shape; this shape keeps the seal firmly in place once it is mounted. If it is necessary to glue the gasket onto the glass pane, the gasket must have a special adhesive layer. The adhesive must be removed in such a way that it does not damage the gasket in any way (eg even when rolled in rolls at

And the adhesive must be durable and have properties that compensate for differences in thermal expansion properties of glass and gasket materials (eg, they must always be elastic). All this inevitably results in the seal being more expensive compared to a standard seal.

The designed window panel can be mounted on window frames of all types - wood, PVC, aluminum or fiberglass. This means that there is no need to change a large number of nuts, tools and other components in the manufacture of wooden, PVC and aluminum windows, as the frame, fittings and passing track remain unchanged while there are no wings in the window structure.

Compared to the known standard designs where the window panel is mounted on the sash, the new design of the window profile has irrefutable advantages:

- increase in window permeability, on average by 20%;

- increased thermal preservation by increasing window panel thickness up to 52mm (30%);

- Reduction (by 25%) of the manufacturing cost of the structure, thanks to the reduction in the number of profiled elements (no wing design in the design) and the elimination of the entire range of manufacturing operations.

BRIEF DESCRIPTION OF THE DRAWINGS

In order to clarify the nature of the claimed utility model, a drawing (Fig. 1) of a window section of the window unit is illustrated which illustrates securing a window panel on a frame in the manner of the panels inserted in the cutout in the separating frame.

Examples of technical solution

Below, by way of example of a specific design of a window unit with a triplex window panel 2, information is presented which confirms the possibility of implementing a utility model with the above-mentioned main and complementary technical objectives. The window unit consists of a frame 1, a three-level window panel 2 with glass panes separated by plastic frames 3 and 4, and a molding 5 covering the inner ledge adhered to the window panel 2 with a gasket 6 mounted in its recess. A special cut-out 7 for installing the panels 2 in one of the separating frame profiles 4 is used to attach the window panel 2 to the frame 4.

If it is not necessary to ensure the thermal insulating properties of the window (e.g. at internal partitions), the separating frames 4 may be made of aluminum, sometimes steel.

The separating frame 4 (both standard and one with the cutout 7 for the panels 2) in the window panel 2 is fixed (glued) to the glass sheet by special tight sealing means which can withstand heavy loads and ensure that the window panel 2 is sealed for a long time.

Therefore, the window panel 2 in the window is assembled in a standard process - with two separating frames 3, 4, with the profile of one of them having a slot 7 for the panels 2.

The manufacturing method and assembly of the claimed window unit structure is described below.

The plastic profiles of both the strip 5 and the separating frame 4 are obtained by pressing PVC.

The profile of the separating frame 4 is cut to the required dimensions for a rectangular joint, after which the working parts are welded together as a standard PVC profile, thereby obtaining the separating frame 4 in the form of a rectangle. The separation frame 4 is installed on the window panel 2 in accordance with standard window panel assembly processes 2 and fastened with an adhesive sealant. After treatment, the necessary fillers 2 are mounted in the cutout 7 for the separator frame profile fillers 4.

The profile bar 5 is cut to the required dimensions for a rectangular joint, then the work pieces are welded together as a standard PVC profile (with the obtained frame structure of the bar 5 in the form of a rectangle). The standard window seal 6 is installed (wound) in the cutout of the strip 5. Further, the strip 5 is glued to the window panel 2 (with the panels already mounted) with a special sealant. When the gasket 6 is installed, the entire structure can be attached to the window frame 1.
