Description

The group of inventions relates to the field of construction, namely, to the frame structure of a window block, which is an integral element of a wall or roof structure and is intended for communication of internal rooms with the surrounding space, natural lighting of the rooms, their ventilation, protection against atmospheric and noise influences, and its assembly units - sash (sash element).

According to GOST 23166-99 “Window blocks. General specifications ":

The window unit is a translucent structure designed for natural lighting of the room, its ventilation and protection against atmospheric and noise influences. The window unit consists of assembly units: boxes and sash elements, built-in ventilation systems (independent or integrated into the hardware), and may include a number of additional elements: shutters, shutters, etc.

A box (frame) is an assembly unit of a window block of a frame structure intended for hinging sashes (or paintings), fixedly fixed (built-in) to the walls of the window opening.

Sash, sash element - an assembly unit of a window block of a frame structure with translucent filling (double-glazed window), connected to the frame using fittings (usually by means of a hinge or sliding connection) installed in a special groove in the sash, serves to provide the window opening function.

A double-glazed unit is a three-dimensional product consisting of two or more sheets of glass, interconnected along a contour with the help of distance frames and sealants, forming hermetically closed chambers filled with dried air or other gas. The glass unit is fixed in the casement using a glazing bead, which also contributes to the glass unit being pressed firmly against the seal located in the overlay (the projection of the casement profile, designed to install a gasket and covering the gap in the anvil) of the casement, which prevents water from entering the casement.

The main disadvantages of this design of the window unit and its wings are:

1. Low light transmission (the main function of the window) due to the large overall dimensions of the sash profiles.

2. Low heat saving due to the limited choice of thickness of the glass unit used: an increase in the thickness of the glass unit requires the creation of a more massive sash profile.

3. The high cost of the design of the window unit due to the large number of components, including a large specific gravity (~ 50%) of profile elements in the material cost of the structure.

The closest in the set of essential features to the claimed constructions of the window unit and the casement of the window unit are the known (RU, patent No. 98213 U1) window unit and its casement, the function of which in the window unit is double-glazed.

The well-known window unit adopted for the prototype consists of a frame and a sash in the form of a double-glazed window with a spacer between adjacent windows made of a profile with a groove for fittings necessary to fix the double-glazed window in the frame, and attached along the perimeter of the glass and closing the inner vestibule of the casing with installed in it groove seal.

The reasons that impede the achievement of the following technical result include the high cost of the product (window unit) and its low quality, due to the low manufacturability of the product design.

The task to which the claimed group of inventions is directed is to modernize window structures with the aim of using resource-saving technologies in their manufacture.

A single technical result obtained as a result of the implementation of the group of inventions is to increase the manufacturability of the product design, aimed at reducing the complexity of manufacturing the product and its cost.

The specified technical result for the object “sash window unit” is achieved due to the fact that in the sash of the window unit, consisting of two or more sheets of glass, interconnected along the contour of the spacer frame, in the groove of which is designed to fix the sash in the frame of the window unit , and attached on the outside of the glasses, along their contour of the platbands of the frame structure, covering the outer and inner porches of the window unit, the remote frame and frame structures of platbands received Performan division into three parts of the frame member starting PVC profile. In this case, as a rule, a seal is installed in the groove of the platband closing the inner vestibule.

The specified technical result is achieved for the object “window block” due to the fact that the window block contains a frame and a sash built into the window opening, consisting of two or more sheets of glass, connected by a distance with a distance frame, in the groove of which is installed for fixing the sash in the frame of the window block fittings, and glasses attached on the outside, along their contour of the frame platbands that cover the outer and inner vestibules of the window block, in which the distance frame and frames Meth structure casings obtained by dividing into three parts the frame member starting PVC profile. In this case, as a rule, a seal is installed in the groove of the platband closing the inner vestibule.

The advantages of the proposed design of the sash of the window unit and, accordingly, the window unit as a whole is the reduction in the number of components requiring precise combination of sizes.

1) In the casement of the prototype, where the distance frame and the frame construction of the platbands are made of three different from each other PVC profiles, it is necessary to precisely combine the dimensions:

- double-glazed windows (sheets of glass connected by a distance frame) and platbands;

- sheets of glass with the dimensions of the distance frame.

2) In the claimed casement design, where the distance frame and the casing frames were obtained by dividing into one of the three longitudinal parts of the frame element one of the original PVC profile, it is only necessary to combine the dimensions of the welded frame casement element from the original PVC profile and glass. The combination of the dimensions of the glass sheets with the dimensions of the distance frame and the dimensions of the casing is ensured by the fact that all the frame elements of the sash are obtained from one PVC profile by dividing it after welding and cleaning the welds. Thus, dimensional accuracy is ensured even at the stage of manufacturing the initial PVC profile of the sash during the extrusion process, where it is much easier to achieve the required accuracy.

Reducing the number of initial PVC profiles for the manufacture of sash elements to one reduces a) the likelihood of errors in the process and b) the number of monitored parameters, which leads to lower costs (reduced enterprise resources spent on the entire technological process of manufacturing the product) and improve the quality of the finished product products.

The claimed design of the product ensures its manufacture according to the most efficient technology in comparison with similar designs of the same purpose.

To clarify the essence of the claimed invention presents the following graphic materials:

- figure 1 - the design of the window unit;

- figure 2, which shows:

a) a section of the original PVC profile 9 for the manufacture of the frame element of the sash according to the claimed technology;

b) an intermediate result of the separation of the sash frame element from the initial PVC profile;

c) sectional profiles of three frame elements (distance frame 4 and two platbands 6, 7).

The following is an example of a specific design of a window unit that provides information confirming the possibility of implementing the claimed group of inventions to obtain the above single technical result.

The window unit (Fig. 1) consists of a frame 1 and a sash 2 built into the window opening, consisting of sheets of glass 3, separated by a spacer frame 4, in the profile groove of which is installed hardware 5, intended for fastening the sash in the frame of the window block, casing 6, closing the outer narthex, and closing the inner narthex of the clypeus 7, in the groove of which a seal 8 is installed.

A remote frame (both standard and with a groove) in a double-glazed window is fastened (glued) to the glass with the help of special adhesives-sealants that withstand a large load and ensure the tightness of the double-glazed window for a long period of time.

A method of manufacturing a sash window unit includes a sequence of the following operations.

1. Cutting the original PVC profile (figa) into a "mustache" on the workpiece in size, calculated so that after welding to obtain the required frame element of the sash.

2. Milling in the blanks of the initial profile of the holes for drainage, ventilation, installation of fittings, fastening handles, etc. using special cutters.

3. Welding the blanks of the PVC profile to obtain a frame element of the sash with the subsequent removal of the flash (stripping of welds).

4. The division (sawing) of the frame element of the sash into three frame elements (figb):

- distance frame

- platband covering the inner vestibule,

- platband covering the outer vestibule.

Separation (sawing) of the sash frame element is carried out using a milling machine with a vertical shaft arrangement. A ram cutter is located on the shaft, with the help of which the platbands are separated in series, in two passes, and excess partitions of the distance frame profile are cut off.

5. The manufacture of a double-glazed window, which includes: cutting glass to a predetermined size, washing and drying it; falling asleep in the remote frame of the dehumidifier; applying a sealant of the first layer to the ends of the distance frame; assembly of a double-glazed window, which includes the installation and gluing on a glass of a remote frame, the pressing of a double-glazed window and the sealing of its ends with a second layer sealant.

6. Rolling the seal in a special groove in the clypeus, covering the inner vestibule.

7. Application of sealant to platbands and gluing them to glass, polymerization of sealant within 1.5-2 hours.

8. Installation and fastening of fittings in the groove of the remote frame.

The leaf obtained as a result of these operations is ready for installation in the window unit frame.
