Description

The invention relates to the design of devices for attaching suspended ceilings, installation of false ceilings, as well as decorative suspended ceilings and partitions.

For fastening suspended ceilings, various mounting devices (frames) are used, which are fixed to the ceiling or walls, for example [EP 3545, E04B 9/30, B44C 7/02, 06/26/2003; FR 2811693, E04B 9/30, B44C 7/02, 02/21/2003], which are made in the form of a figured profile with means for attaching the paintings, and in the figured profile there is a longitudinal groove of a U- or V-shape for placement and fixing of the canvas attached to a longitudinal part, fixed in the longitudinal hole of the baguette, and aluminum is used as the material for their manufacture.

The disadvantage of these technical solutions is the relatively large consumption of materials and their electrical conductivity, which leads to a relatively low electrical safety when used in rooms with electrical wiring.

A close analogue of the proposed is a baguette for attaching a stretch ceiling [RU 31591, U1, E04F 19/00, 08/20/2003] containing a profile consisting of a horizontal shelf connected to a rear vertical wall having a latch, as well as with a front vertical wall, on the protruding edge of which a rounded protrusion is formed, the profile being supplemented by a vertical shelf connected to the horizontal shelf, the vertical shelf and the rear vertical wall of the profile being in the same plane, and the width of the horizontal shelf is limited The distance between the front and rear vertical walls.

The disadvantage of this technical solution is its relatively low strength, which is manifested during the installation of relatively large canvases of suspended ceilings, as well as when attaching other relatively heavy hanging elements.

The closest in technical essence to the proposed one is a baguette for attaching a stretch ceiling [RU 54064, U1, E04F 19/00, E04B 9/00, 06/10/2006], containing a figured profile forming open cavities for setting the borders of adjacent canvases of the stretch ceiling and consisting from the V-shaped central rib combined with a profiled horizontal shelf with elements for fixing the bordering of the paintings and two inclined side ribs made parallel to the corresponding sides of the central rib, as well as a decorative insert for cutting off the entrance to said cavities, configured to interact with the central rib and the inner surfaces of the side ribs, the central rib of the profile being made with a flat end, the edges of the inner surfaces of the side ribs made rounded, and the decorative insert is made in the form of a figured elastically deformable tape having a horizontal shelf , the rounded edges of which are conjugated with the corresponding rounded edges of the side ribs of the profile, a vertical wall resting on the end face centrally th ribs of the profile, as well as two wings interacting with the inner surfaces of the side ribs.

The disadvantage of the closest technical solution is the relatively low strength, which is manifested during the installation of relatively large canvas stretch ceilings, as well as when attaching other relatively heavy hanging elements.

The problem to which the present invention is directed, is aimed at creating a baguette for attaching a stretch ceiling with increased strength and which is lightweight at the same time, is non-conductive, inexpensive and technologically advanced.

The required technical result is to increase the strength of the baguette for attaching a stretch ceiling.

The problem is solved, and the required technical result is achieved by the fact that a baguette for attaching a stretch ceiling, containing a profile forming at least one open cavity for institution bordering the canvas stretch ceiling, and elements for attaching the border of the canvas, according to the invention is made of composite material , which is a mixture of a filler and a binder, while the fibrous material is used as a filler, and a polymer resin in the following materials is used as a binder ratios wt.%:

fibrous material 20-80 polymer resin rest

In addition, the desired technical result is achieved in that either fiberglass, or chemical fiber, or carbon fiber is used as the fibrous material, and either polyamide resin, or epoxy resin, or phenolic resin, or acrylic resin is used as the polymer resin.

In addition, the desired technical result is achieved in that the profile is equipped with at least one reinforcing metal bar mounted along the profile.

In addition, the desired technical result is achieved by the fact that the profile is made with a thickness of 1.2 to 2.5 mm.

The invention is illustrated by drawings.

in FIG. 1 presents one of the options for a possible baguette for attaching a stretch ceiling;

in FIG. 2 - another embodiment of a possible baguette for attaching a stretch ceiling is presented.

A baguette for attaching a stretch ceiling is made in the form of a profile with a base 1 and at least one (Fig. 2) or two (Fig. 1) open cavities 2 to establish a border for the stretch ceiling and elements 3 for attaching the border of the canvas.

In addition, the profile 1 may contain in its base at least one reinforcing metal bar 4, installed along the profile, or in the base 1 (Fig. 2), or in the element 3 for attaching the border of the canvas (Fig. 1).

According to the invention, the baguette for attaching the stretch ceiling is made of a composite material that is a mixture of a filler and a binder, with the fibrous material being used as the filler, and a polymer resin in the following ratios of mass% used as the binder:

fibrous material 20-80 polymer resin rest

In a baguette for attaching a stretch ceiling, the base 1 is used for fastening to a ceiling or wall, and open cavities 2 are either V-shaped (Fig. 1) or U-shaped (Fig. 2), but can also have a different shape. The base 1 can be made with a thickness of 1.2-2.5 mm, which provides sufficient strength, taking into account the material used for making the baguette, with a radius of curvature of the edges of 1.2-2.5 mm. With a thickness of less than 1.2 mm, the strength of the material is not enough to securely fix the baguette to the base surface, and with a thickness of more than 2.5 mm, the strength is excessive and the material consumption of the product is unnecessarily increased.

A baguette for attaching a stretch ceiling is made of composite material by pulling a fibrous material (or fiberglass, or chemical fiber, or carbon fiber) impregnated with a polymer resin (or polyamide resin, or epoxy resin, or phenolic resin, or acrylic resin) through a shaping die ( pultrusion). The weight ratio of the fibrous material to the polymer resin is performed in the ratio: from 20% to 80% - fibrous reinforcing material, the rest is polymer resin. When the amount of fiber reinforcing material is less than 20%, the baguette is too fragile and not strong enough. When the amount of fiber reinforcing material is more than 80%, the elasticity is lost and the rigidity of the baguette is reduced. After that, the finished profile is aged until cured and ready for use. In the same way as fiber, a reinforcing metal wire, for example of aluminum, can be pulled through the die at the same time as the fiber. Such reinforcing wire will increase the lateral rigidity of the baguette.

Examples of specific performance.

Example 1. 21 wt.% Fiberglass in the form of 100 tex threads is passed through a die and impregnated with 79 wt.% Polyamide resin grade PO-300 in a bath before a die. Then the threads are pulled through the mold and cured.

Example 2. 50 wt.% Chemical fiber (nylon) in the form of 110 tex threads is passed through a die and impregnated with 50 wt.% Epoxy resin grade ED-20 before a die. Then the threads are pulled through the mold and cured. Curing can be accelerated by heating the die. The percentage can be adjusted by changing the number of threads.

Example 3. 30 wt.% Carbon fiber brand GRAPAN-27 in the form of filaments with a diameter of 0.3 mm is passed through a die and impregnated with 80 wt.% Acrylic resin brand Technacryl in front of the die. Then the threads are pulled through the mold and cured.

Example 4. 30 wt.% Carbon fiber brand GRAPAN-27 in the form of filaments with a diameter of 0.3 mm is passed through a die and impregnated with 70 wt.% Phenolic resin in front of the die. Then the threads are pulled through the mold and cured.

Using the design of the baguette made of composite material allows you to get a high-strength design of the baguette, characterized by lightness, strength, sufficient flexibility without permanent deformation, cheapness, almost absolute corrosion resistance and almost absolute moisture resistance. The design of the baguette is such that it can be easily and simply made, assembled false ceilings and bent according to any patterns.
