Description

The utility model relates to construction, and specifically to the profile forming an impost in the manufacture of window and door blocks, display cases, dividing walls and other glazing systems, which is made of polyvinyl chloride.

A profile is known that forms an impost made of polyvinyl chloride, which has a T-section with the main part and a shelf protruding from both sides (RU U1 No. 54999, IPC 8 E06B 3/00, 2006). The main part is made with a central cavity mating through an internal partition with a small cavity located at the end of the central part, opposite the end with the shelf. On the other hand, the central cavity through the internal partition mates with the cavities of the shelf, made with four cavities sequentially spaced across the width of the shelf, separated by partitions. The first partition is located along the symmetry axis of the section between the outer wall of the shelf and the partition with the central cavity, and the second and third partitions are symmetrically located and each of them lies between the profile wall, forming the outer surface of the profile shelf from its outer side, and the walls forming the outer surfaces of the shelf inside the corners between the sides of the shelf and the main part. The second and third partitions are made inclined towards the central part of the profile.

The well-known profile, forming an impost, has insufficient thermal insulation parameters. The exposed part with protrusions easily transfers the temperature to the main cavity, where the highly conductive metal reinforcement is located to give the assembled structure a stiffness, which is interfaced by an internal partition separating the central cavity from the small cavity formed on the other side by a profile wall open inside the room. Conducted by a metal armature having good heat-conducting characteristics, the temperature is easily transferred to the profile wall, which is open inside the room, reducing the degree of ensuring the heat-insulating properties of the assembled frame.

The technical result, the achievement of which provides a real utility model, is to increase the heat-insulating properties of the profile forming the impost, while maintaining its rigidity, as well as decorative qualities.

The achievement of the specified technical result is ensured by the implementation of the profile of PVC, forming an impost, which has a T-shaped cross section with the main part and a shelf protruding from both sides. The main part is made with a Central cavity, mating through internal partitions with located on opposite sides, one on the side of the shelf and the second on the opposite side of the shelf, additional cavities. An additional cavity from the side of the shelf is interfaced through the internal partition with the cavity of the shelf.

In the best embodiment of the utility model, located on the side opposite the shelf, the additional cavity of the main part is divided into four chambers by partitions forming the shape of a cross in the cross section of the profile. In the particular case of the utility model, these cross-shaped partitions are mated to each other at angles other than straight.

In the best embodiment of the utility model, the cavity of the shelf is made with four sequentially arranged chambers separated by a central and side partitions, the central partition is located along the symmetry axis of the section between the outer wall of the shelf and the partition with the additional cavity of the main part, the side partitions of the cavity of the shelf are symmetrical and each of them lies between the profile wall forming the outer surface of the profile shelf from its outer side and the walls forming the outer surface The shelves are inside the corners between the sides of the shelves and the main part.

The two shelves connected with the central partition of the chamber in the best embodiment of the utility model are additionally separated by an intermediate partition, which forms a cross with the central partition in the cross section of the profile and mates with the ends of the shelves from the sides.

The partition between the cavity of the shelf and the additional cavity of the main part may have an obtuse angle in the cross section of the profile in the preferred embodiment of the utility model with a vertex located at the interface with the central partition of the cavity of the shelf.

The side partitions of the cavity of the shelf may have, in a preferred embodiment, a utility model in cross section of an obtuse angle shape profile with vertices located at the interface points with the intermediate partition.

The development of the system of cavities and internal profile chambers provides an increase in the thermal insulation properties of the profile and its rigidity. Implementation of the design in accordance with particular cases of the utility model execution contributes to the increase of these effects. The implementation of partitions with orientation at angles and in the form of angles helps to increase the flatness of the outer surfaces of the profile by eliminating the weights.

The utility model is illustrated by a specific example of a profile forming an impost in the manufacture of a frame, the cross section of which is shown in the drawing.

The profile has a T-shaped section with the main part and a shelf protruding from both sides.

The main part is made with a central cavity 1, mating through internal partitions 2 and 3 with located on opposite sides, one (2) on the side of the shelf and the second (3) on the opposite side of the shelf, additional cavities 4 and 5. Additional cavity 4 with side of the shelf is connected through the internal partition 6 with the cavity of the shelf.

Located on the side opposite the shelf, the additional cavity 5 is divided into four chambers by partitions 7 and 8, forming the shape of a cross in the cross section of the profile and mating with each other at different angles.

The cavity of the shelf is made with four sequentially arranged chambers 9-12, separated by a central 13 and side partitions 14 and 15. The central partition 13 is located on the axis of symmetry of the section between the outer wall 16 of the shelf and the partition 6. The side partitions 14 and 15 are symmetrical and each of them lies between the outer wall 16 and the walls 17.

The chambers 10 and 11 conjugated with the central partition 13 are separated by an intermediate partition 18, which forms a cross shape with the central partition 13 in the cross section of the profile and mates with the side partitions 14 and 15. The partition 6 has an obtuse angle in the cross section of the profile with the vertex 19 located at the point of interfacing with the central partition 13. The lateral partitions 14 and 15 in the cross section of the profile also have obtuse angles with vertices 20 and 21 located at the points of interfacing with the intermediate partition 18 . (RU U1 No. 80187MPK E06v 3/22 publ. 01/27/2009).

The disadvantage of this analogue is the difficulty of manufacturing due to the presence of two additional transverse partitions made in the shelf and in the additional cavity from the side opposite the shelf, in the description of patent No. 80187 these crossbars are designated as position 7 and position 18, - the partition forming a shelf with a central partition 13 in the cross section of the profile of the shape of a cross and mated with ends with side partitions 14 and 15.

The purpose of the crossbars 7 and 18 is twofold: on the one hand, additional cavities are formed with their help, which increase the thermal insulation properties of the profile, and on the other hand, they increase the stiffness of the PVC profile.

According to the Interstate standard “PVC profiles for window and door blocks” GOST-30673 1999, depending on the functional purpose (according to the perception of loads as an integral part of the design of window and door blocks), the profiles are divided into main and additional.

According to the design, depending on the number of rows of internal chambers across the width of the section, affecting the thermal characteristics, the main profiles are divided into: one-, two-, three-, four-chamber and more.

Polyvinyl chloride profile (PVC profile) is a pipe divided by internal partitions into air compartments - chambers. In the middle of the profile system is a reinforcing insert made of galvanized steel. This heat-conducting element is surrounded by side chambers, which, in turn, are divided into subchambers. The more such compartments (especially on the outside of the profile), the better.

An increase in the number of cameras increases the cost of core products and, ultimately, the window product as a whole. When choosing a profile system, the climatic conditions of the region, the construction of the walls, the thermal regime of the building, etc. should be taken into account. Three-chamber profile systems are suitable for small windows (it is desirable that the walls are not too thick, and openings with a warm quarter). Six-chamber systems make it possible to increase the energy efficiency of a house and minimize heating costs.

Depending on the resistance to climatic effects, products are divided by type of execution:

- normal execution - for areas with an average monthly air temperature in January of minus 20 ° C and above (control load during testing - minus 45 ° C) in accordance with applicable building codes;

- frost-resistant design (M) - for areas with an average monthly air temperature in January below minus 20 ° C (control load during testing - minus 55 ° C) in accordance with applicable building codes.

Depending on the thickness of the front and non-facial external walls, the main profiles are divided into three classes - see Table 1.

Table 1 Outer wall Thickness of external walls, mm, not less than for classes BUT AT FROM Front wall 3.0 2,5 Not standardized Front wall 2,5 2.0 Also

The thickness of the inner walls of the profiles is not standardized.

Wall thickness is an indirect characteristic of shape stability and strength of profiles.

The following definitions for PVC profiles have been established in the business turnover:

1) economical

1. The profile system consists of three air chambers, which determines the relatively low cost of the final product

2. The mounting depth of the box is 58, 60 or 70 mm. Some systems are compatible with a wide frame from a depth of 100 mm, which is less prone to freezing in adverse operating and climatic conditions.

3. Two sealing circuits provide a reliable fit of the flaps to the frame, prevent blowing, moisture and dust.

4. In terms of strength indicators, the profile is not inferior to systems of a higher class. The wall thickness is 3 mm, which ensures the stability of the window.

Signs of the so-called practical PVC profile:

1. The system profile consists of four or five air chambers. The developed structure provides enhanced heat and sound insulation properties

2. The mounting depth of the box is 70 mm. The increased contact area of the window block to the walls of the opening (and, therefore, the mounting seam) prevents the wall from freezing.

3. Two or three sealing circuits provide a high level of window tightness.

4. The increased strength characteristics make it possible to produce window structures of a large area

The following categories (premium classes) involve the use of five- to six-chamber profiles intended for use in regions with harsh climates.

Optimal for central Russia is a PVC profile with the following characteristics:

Number of cameras: - 3 System Class: - AT; Mounting Depth, mm: - 70; Filling Thickness, mm: - from 12 to 40;

For a universal system designed for different climatic zones and a variety of construction objects, the following parameters of the PVC profile are required:

Profile Height:

- boxes - 60 mm, sashes - 80 mm, impost - 78 mm;

Number of seal loops - 2; Seal overlap, mm - 8; Nipple clearance, mm - 3; Falzluft, mm - 12; The offset axis of the locking device, mm - 13 Depth, mm - twenty; Bead height, mm - eighteen; Maximum filling thickness, mm - 40.

For a three-chamber profile with a maximum filling thickness of 40 mm and an outer wall thickness of 3 mm, the additional stiffness of the profile obtained by the transverse partitions in the shelf and in the additional cavity adjacent to the central cavity from the opposite side shelf, as well as an increase in the thermal insulation properties of the profile beyond due to the presence of four additional cavities in the shelf and two additional cavities in the additional plane adjacent to the central cavity from the side opposite the shelf, it does not have a noticeable effect Ia neither rigidity nor on its thermal insulation properties. At the same time, as the design of the profiles forming the impost is significantly simplified, the material consumption of the product is reduced, slightly, but the weight of the product is reduced.

The noted advantages are the technical result to which the claimed utility model is directed.

Figure 1 shows the profile forming the impost, according to the claimed utility model. Figure 1 adopted the following notation,

1 - profile forming an impost made of polyvinyl chloride and having a T-shaped cross section with the main part and the shelf protruding from both sides of the shelf%

2 - the Central cavity of the main part, conjugated on the one hand through the partition 5 with an additional cavity 14, on the other - through the partition 3 with an additional cavity 4;

the main part through the partition 6 is paired with a shelf having four cavities 10, 11, 12 and 13, separated by additional partitions 7, 8 and 9.

Additional partitions of the cavity of the shelf are made inclined towards the main part of the profile.

Due to the inclined arrangement of the additional partitions of the cavity of the shelf, it is possible to remove the weights from its front surface, since each of the forces applied to the profile wall from the side of the second and third partitions, when they are inclined, can be decomposed into two mutually perpendicular components and the magnitude of the component perpendicular to the profile wall, obviously, less than in the case of a force acting in the same direction when the partitions are located at right angles, that is, in the case when the forces from the action are burned out ok will not be split into mutually perpendicular components ..

The presence of an additional cavity on the side of the shelf provides the level of thermal insulation properties of the profile necessary for the selected climatic zone, and its division into chambers by jumpers allows to increase the stiffness of the profile and eliminate the sagging of surfaces formed by the walls open outward in the zone of the additional cavity.

The partitions of the additional cavity of the main part mate with each other at angles other than straight, which leads to an increase in the manufacturability of the profile, since in the manufacture of the die it is much easier to place inserts forming the cavity of the profile, and pinning of the inserts in the die body is possible only with the location of the partitions other than the orthogonal .

The central partition of the cavity of the shelf is located on the axis of symmetry of the section between the outer wall of the shelf and the partition with the central cavity, and additional partitions of the cavity of the shelf are symmetrically and each of them lies between the wall of the profile forming the outer surface of the shelf of the profile from its outer side and the walls forming the outer the surface of the shelf inside the corners between the sides of the shelf and the main part, while the second and third partitions of the cavity of the shelf are located at an angle to the walls mating with it.

Additional partitions of the cavity of the shelf are made inclined towards the main part of the profile.

The partition between the cavity of the shelf and the additional cavity of the main part has an obtuse angle in the cross section of the profile with the apex located at the interface point with the central partition of the cavity of the shelf. Such its implementation in the form of an obtuse angle increases the flatness of the outer surfaces of the profile by eliminating the weights.

The profile is manufactured on a twin-screw extruder by extrusion of a powdered composition with vacuum calibration. The production and assembly of window or door blocks is carried out according to generally accepted technology.

The technical result, the achievement of which is provided by the claimed utility model, is to reduce the weight and material consumption of the structure, simplify manufacturing technology in compliance with the required strength characteristics
