Description

The utility model relates to the field of construction, in particular to the supporting profile for the installation of suspended ceilings with the formation of niches that allow them to place lighting devices, curtains, paintings, etc., in different premises.

A support profile is known for mounting a stretch ceiling (Patent RU No. 855513, E04B 9/18, publication date 08/10/2009), consisting of one shelf and two symmetrical ribs rigidly connected to it, forming an open cavity, inside of which parallel to each other are made on the ribs grooves for fixing the stretch ceiling web using glazing bead. The connection angles of the shelf and ribs are rounded. The supporting profile is made with the possibility of fastening, mainly to the wall of the room by means of threaded connections installed through coaxial through holes in two ribs. The bead is made with a cross section of a triangular or similar shape and is placed in the grooves of the bearing profile located farther from the end of the ribs. The crevice gap formed in this case between the stretch ceiling web emerging from the open cavity and the rib adjacent to the wall should be overlapped by means of a decorative element fixed in grooves of the bearing profile located closer to the ends of the ribs.

The disadvantages of the known bearing profile are:

- the need to use a decorative element to close the gap gap and ensure the appearance of the stretch ceiling and the room as a whole, which increases the complexity of installing the stretch ceiling;

A shorter rib at the bottom is made with a double-sided gear lock for attaching a decorative element. A longer rib in the lower part is made in a rectangular section. To increase the rigidity of the supporting profile and the reliability of fastening the web of the stretch ceiling, the profile contains additional stiffeners made in the form of an internal jumper between the ribs with the formation of a closed cavity between it, the shelf and the ribs, and / or in the form of a third rib made in the form of a brace, is rigidly connected with a jumper and a longer rib in an open cavity, and / or in the form of a profile strip of a flat, triangular or rectangular section, rigidly connected to a shelf on its outer side. The supporting profile is made with the possibility of fastening mainly to the wall of the room by means of threaded connections installed through coaxial holes in the ribs in the area between the shelf and the jumper. The supporting profile can also be used for the installation of suspended ceilings with the formation of niches by attaching it to the wall of the room through an intermediate supporting element. Fixation of the stretch ceiling web inside the supporting profile is carried out by means of a “harpoon”. In this case, the gap between the web of the stretch ceiling emerging from the open cavity and the rib adjacent to the wall should be overlapped by means of a decorative element fixed in grooves of the supporting profile located closer to the ends of the ribs.

A disadvantage of the known supporting profile is the need to use a decorative element to close the gap gap and ensure the appearance of the stretch ceiling and the room as a whole, which increases the complexity of installing the stretch ceiling.

The utility model is based on the task of improving the design of the supporting profile due to the different execution of its ribs, eliminating the formation of a gap gap with the canvas of the stretch ceiling during its installation.

The technical result from the implementation of this task is to reduce the complexity of installing a stretch ceiling with the formation of a niche while providing a better appearance of the stretch ceiling and the room as a whole.

The problem is solved due to the fact that in the supporting profile, consisting of at least one shelf and rigidly connected to it at least two ribs of different lengths, forming an open cavity, inside of which a transverse protrusion is made on the smaller length rib for attaching the stretch ceiling web , according to a utility model, the transverse protrusion is made in the lower part of the rib of a shorter length, and the rib of greater length in its lower part is made with a cantilever shelf facing towards the rib of a shorter length, while the length of the said shelf ybiraetsya conditions of opening overlap in the open cavity.

In this case, it is advisable that the supporting profile contains one shelf and three ribs rigidly connected to it, while the third rib is located on the opposite side of the rib of shorter length and is additionally connected to the shelf by a strut, the base of which is rigidly connected to the shelf on the opposite side of the rib longer length.

It is advisable that the third rib was made in the same plane with the rib of shorter length.

It is advisable that the third rib was made with an offset to the outside relative to the rib of shorter length.

It is advisable that the third rib was made with longitudinal sawtooth teeth on its outer side.

It is advisable that the supporting profile contains two shelves and two ribs, while the second shelf was located under the first shelf and made in the form of an internal bridge between the ribs with the formation of a closed cavity between it, the shelf and the ribs.

It is advisable that in the open cavity a longer rib is additionally rigidly connected to the jumper by means of a strut.

It is advisable that the supporting profile contains two shelves and three ribs, while the second shelf was located under the first shelf and made in the form of an internal bridge between the ribs with the formation of a closed cavity between it, the shelf and the ribs, and the third rib is made in the form of a console in one plane with a shelf on the side of a rib of shorter length.

It is advisable that in the open cavity a longer rib is additionally rigidly connected to the jumper by means of a strut.

It is advisable that the cantilever shelf in the lower part of the longer rib is parallel or at an angle to the corresponding shelf or jumper, which forms an open cavity with the ribs.

It is advisable that the rib of greater length in the place of formation of the shelf was made with a rounding or with a thickening facing its outer side.

The design of the carrier ensures the achievement of the claimed technical result. By making a longer rib in its lower part with a cantilevered shelf facing the side of a smaller rib, and with the length of the said shelf, which is selected from the condition of opening the opening in the open cavity, the gap between the edge of the stretch ceiling web coming out of the open cavity is eliminated , and an edge of shorter length, and due to this, the need to use a decorative element to ensure the appearance of the stretch ceiling and the room as a whole is eliminated. This embodiment of the lower part of the rib of greater length also creates conditions for changing the design of the rib of shorter length by performing in its lower part of the transverse protrusion. In general, this allows to reduce the laboriousness of installing a stretch ceiling when installing niches of different functional purpose and sizes between the canvas of the stretch ceiling and the wall of the room, which can be used, for example, for placing lighting fixtures, hanging curtains, etc.
