Description

The field of technology.

The claimed technical solution relates to the field of construction of suspended ceilings, namely, to devices for hanging load-bearing profiles, and is intended for mounting suspended ceilings, including in seismically active areas.

Prior art.

It is known to fix ceiling sandwich panels using TAUL.01 aluminum profiles manufactured by Castel Engineering (Belgium) (Internet resources

https://web.archive.org/web/20190912230128/coolprofile.ru/uses.php, https://web.archive.org/web/20161022075149/http://coolprofile.ru/prod04.php, https: //web.archive.org/web/20191022003234/http://www.castel-engineering.com/en/omega-60.htm, http://www.castel-engineering.com/en/omega-60. htm). As in the claimed technical solution, the specified analogue contains an aluminum omega-shaped profile containing two horizontal shelves for stacking sandwich panels and a mounting channel with horizontal abutment edges. In contrast to the claimed technical solution, a rectangular metal nut is placed in the mounting channel, into which a metal stud is screwed. The other, upper end of the stud is attached to the ceiling element. Sandwich panels are laid on the profile shelves and fixed to it with screws. When using the known fastening, the sides of the profile are supported on the nut by the weight of the profile and the sandwich panels fixed to it.

The disadvantage of this analogue is the design of the fastening, in which the profile with its sides freely lies on the rectangular nut. In this case, the profile and the sandwich panels fixed to it can rise up as a result of shaking during equipment operation or seismic activity. This causes a weakening of the fastening of the sandwich panels to the profile, as well as the appearance of working out (abrasion) of the sides in the place of their contact with the rectangular nut. This reduces the reliability and useful life of the mount. The contact of the metal parts of the fastening, located under and above the sandwich panels, leads to the fact that the fastener has a high thermal conductivity. This reduces the effectiveness of the ceiling mounted using an analogue fixture, when it is required to provide thermal insulation of the internal and external space, that is, in most cases of use of sandwich panels.

Disclosure of the proposed technical solution.

The technical problem to be solved by the claimed technical solution is to increase reliability.

The technical result provided by the claimed technical solution is to increase the rigidity of fastening the profile and suspension, which leads to the elimination of the free movement of the profile relative to its suspension.

The essence of the claimed technical solution lies in the fact that the fastening of the false ceiling panels contains a profile with one or two horizontal shelves and an installation channel with horizontal stop flanges. It differs in that the said sides are clamped between the nuts of the stud connection or between the head of the bolt and the nut of the bolted connection. The metal elements of the said connection do not directly contact the stop flanges and other parts of the mounting channel. A nut or bolt head of the said connection placed inside the channel is placed inside an insert with low thermal conductivity, and a thermal washer is placed between the nut screwed on the outside of the mounting channel and the flanges.

The above essence is a set of essential features of the claimed technical solution, ensuring the achievement of the claimed technical result.

In special cases, it is permissible to carry out a technical solution as follows.

The upper side of the horizontal flanges, intended for contact with the panels, is preferably provided with a groove with a seal placed therein. The lower edge of the mounting channel and horizontal shelves is preferably at the same level.

The insert and thermal washer can be made of plastic. The insert and the thermal washer can be made together.

The author of the claimed technical solution made prototypes of this solution, the tests of which confirmed the achievement of the technical result.

Brief description of the drawings.

Figure 1 shows a diagram of the fastening of false ceiling panels according to example 1; Fig. 2 is a diagram of the fastening of the false ceiling panels according to example 2; in fig. 3 is a cross-section of a profile with two horizontal shelves according to FIG. 1 and 2; in fig. 4 is a diagram of fixing the junction of the suspended ceiling panel to the wall (wall panel); in fig. 5 is a cross-section of a profile with one horizontal flange according to FIG. 4.

Implementation of the technical solution.

The fastening of the false ceiling panels contains a profile (1) having one (Fig. 4, 5) or two (Fig. 1, 2, 3) horizontal shelves (2) for laying the false ceiling panels (3) (sandwich panels). The profile is made of metal (preferably aluminum) or plastic. The profile with two shelves is designed for joining the suspended ceiling panels to each other. A profile with one horizontal shelf also has one vertical shelf (4) and is intended for joining a suspended ceiling panel to a wall or wall panel. The side of the shelves, which is intended for contact with the panels, is provided with a groove for placing a seal (16), for example, a butyl cord. The upper side of the horizontal shelves (2) and the outer side of the vertical shelves (4) are in contact with the panels.

The profile is also equipped with a mounting channel (5) with horizontal stop flanges (6). The lower edge of the installation channel (5) and the horizontal shelves (2) are flush. This reduces the possibility of contamination of the face of the installed ceiling.

The flanges (6) are clamped between the nuts (8) of the stud joint or between the head of the bolt (7) and the nut (8) of the bolted joint. The mentioned stud connection or bolted connection is made so that the metal elements of this connection do not directly contact the stop flanges (6) and other parts of the mounting channel (5). For this, the stud nut or the head of the bolt (7) of the bolted joint placed inside the channel (5) is placed inside the insert (9) with low thermal conductivity, for example, made of plastic. This insert is preferably made to fill the entire space of the channel (5) in a certain segment, including the space between the flanges (6). At the same time, for the stud connection, they provide the possibility of twisting the stud into the nut located inside the insert (9). A thermal washer (10) made of a material with low thermal conductivity, for example, of plastic, is placed between the nut (8) screwed on from the outside and the flanges (6). The thermal washer can be made together with the insert (9).

Nuts and bolt heads can be square, hex or slotted.

The specified implementation of thermal insulation using an insert (9) and a thermal washer (10) can significantly reduce heat (or cold) losses through the device for hanging the profiles.

The free end of the aforementioned stud or bolt (7) is attached by means of a threaded sleeve (11) and a suspension stud (12) to the ceiling slab or beams, or to mounting elements fixed to the ceiling slab or beams.

Examples of specific implementation.

Example 1.

The profile is made with two horizontal shelves (2) (Fig. 1, 3).

The flanges (6) are clamped between the head of the bolt (7) and the nut (8) of the metal bolted joint. The bolt head is placed inside the plastic insert (9) so that the bolt does not come into contact with the flanges (6) and other parts of the channel (5). The insert fills the entire internal space of the channel, including the space between the flanges (6). In this case, the diameter of the threaded section of the bolt (7) is less than the distance between the flanges.

The nut (8) of the mentioned connection is made with a flange; a plastic thermal washer (10) and an enlarged metal washer (13) are installed between the nut and the flanges (6). The enlarged metal washer is designed to tighten the thermal washer (10) with the nut (8) over the entire area of the thermal washer.

The end of the bolt (7) is connected with a threaded sleeve (11) to the suspension pin (12), which is fastened with nuts and washers to the mounting profile fixed to the ceiling beam. The lower part of the suspension pin is closed with a heat-insulating cylinder (14), made, for example, of expanded polyethylene.

Example 2.

The sides (6) are clamped between the nuts (8) of the metal stud connection (Fig. 2, 3). One nut is located inside an insert (9) made of plastic, made in one piece with a thermal washer (10). In this case, the insert fills the entire internal space of the channel, including the space between the sides (6). Such an implementation of the insert with a thermal washer ensures that the metal parts of the stud joint do not contact the sides (6) and other parts of the channel (5). In this case, the diameter of the stud (15) is less than the distance between the sides.

As in example 1, the outer nut (8) is made with a flange, an enlarged metal washer (13) is installed between the nut (8) and the thermal washer (10).

The end of the stud (15) is fastened with nuts and washers to a mounting rail, which is secured with mounting clamps to a ceiling I-beam (not shown). The lower part of the stud is closed with a thermal insulating cylinder (14) made of polyethylene foam.

Example 3.

The profile is made with one horizontal (2) and one vertical (4) shelves (Fig. 4, 5).

The flanges (6) are clamped between the head of the bolt (7) and the nut (8) of a metal bolted connection made similar to example 1.

The end of the bolt (7) is connected with a threaded sleeve (11) to the suspension pin (12), which is fastened with nuts and washers to the mounting profile fixed to the concrete ceiling. The lower part of the hanger rod is closed with an insulating cylinder (14) made of polyethylene foam.

The implementation of the proposed technical solution is not limited to the above examples. The order of use.

When fixing false ceiling panels, the mounting elements are pre-mounted to the ceiling slab or its beams.

Then inserts (9) with bolts (7) or nuts are installed inside the mounting channel (5), external nuts (8) are screwed onto them, and the profile is suspended from the suspension rods (12) fixed to the mounting elements.

Then the sides (6) of the mounting channel are clamped, at the same time setting the height of the profile placement.

For an abutting profile with one horizontal flange, then fix the profile to the wall panel by placing a seal (16) in the profile groove. Fastening is carried out, for example, using rivets (17) or self-tapping screws.

Then, for a profile with both one and two horizontal shelves, the panels (3) of the suspended ceiling are placed on the profile, installing a seal (16) in the profile groove. Then the panels are fixed to the profile flanges, for example, using rivets (17).

After the panels are mounted on all horizontal shelves of the profile (one or two depending on the profile), the space between the panels is filled with heat-insulating material (18), for example, mounting foam.

From above, the space between the panels is closed with a vapor barrier tape (19), for example, butyl rubber, and from above - with a metal strip (20), fixing it to the panels with rivets (17).

Industrial applicability.

The claimed technical solution is implemented using commercially available devices and materials, can be manufactured at any industrial enterprise and will find wide application in the field of suspended ceiling construction.
