RU224993U1 - PROFILE FOR EDGING OPENINGS - Google Patents

Abstract

The utility model relates to the field of construction, in particular to devices (hatch, door) for closing openings and recesses in the wall and is intended for access to utilities running in the wall (used as a hatch), or can be used as access to premises that should be hidden from outsiders (used as a hidden, secret door). The technical result is increased strength and reliability of fastening the profile to the ends of the window in the gypsum plasterboard coating. The technical result is achieved by the fact that the profile for edging the openings, containing two closed chambers of rectangular cross-section, having a common internal wall between the chambers and having a pair of parallel common (for both chambers) external walls, is adjacent to the corner part of one of the chambers from the outside and is characterized by the fact that that the side shelf is supplemented with a connection unit with the end of the gypsum board, consisting of mounting and painting ribs connected by a horizontal rib. Rectangular chambers can be extended vertically. The side shelf can be made as a continuation of the long vertical wall. Ribbons can be located on the internal surfaces of the mounting ribs facing each other.

Description

The utility model relates to the field of construction, in particular to devices (hatch, door) for closing openings and recesses in the wall and is intended for access to utilities running in the wall (used as a hatch), or can be used as access to premises that should be hidden from outsiders (used as a hidden, secret door).

The “Inspection device with hatch and frame” EP 1903161 [2] is known, containing a circumferential frame profile for receiving cladding from the outside of a frame for cladding walls/ceilings/floors.

The disadvantages of the device include the complexity of installation due to the need for horizontal movement of the plasterboard to install the end between the profile ribs, as well as the insufficient strength and rigidity of the profile.

The closest to the claimed technical solution is “Device for closing openings” RU 193810 [1], which includes a profile for edging openings, containing two chambers of rectangular cross-section having a common wall, with a side shelf adjacent to the corner part of one of the chambers from the outside.

The known device has the strength and rigidity of a profile frame due to the presence of cameras in the profile.

The disadvantage of the known solution is the insufficient strength and reliability of fastening the gypsum board to the profile frame, the increased complexity of installation due to the need for final assembly of the frame on site, for example, on a gypsum board ceiling. Another disadvantage is the impossibility of installing an unobtrusive hatch when the profile framing the opening is not visible on the front side.

The technical result is increased strength and reliability of fastening the profile to the ends of the window in the gypsum plasterboard coating.

The technical result is achieved by the fact that the profile for edging the openings, containing two closed chambers of rectangular cross-section, having a common internal wall between the chambers and having a pair of parallel common (for both chambers) external walls, is adjacent to the corner part of one of the chambers from the outside and is characterized by the fact that that the side shelf is supplemented with a connection unit with the end of the gypsum board, consisting of mounting and painting ribs connected by a horizontal rib, with riffles located on the internal surfaces of the mounting, painting and horizontal ribs facing each other.

Implementation:

The figure shows a diagram of the mounted device, where:

1 – closed chambers;

2 – side shelf;

3 – mounting rib;

4 – painting rib;

5 – bottom sheet of gypsum board;

6 – top sheet of gypsum board;

7 – opening;

8 – horizontal rib;

9 – putty;

10 – standard ceiling installation;

11 – short horizontal wall facing the hatch (front);

12 – internal horizontal short wall;

13 – rear short horizontal wall;

14 – vertical common outer wall facing the opening;

15 – vertical common outer wall facing the coating.

The device operates as follows:

Closed chambers 1 of rectangular cross-section are formed by long vertical walls 14 and 15 common to both chambers, between which and perpendicular to them there are short horizontal walls - front 11, internal 12 and rear 13. The internal short horizontal wall 12 is common to both chambers.

The ceiling, consisting of the upper and lower gypsum boards 6 and 5, respectively, is mounted (suspended) on a standard suspension 10. In the upper and lower gypsum boards, a corresponding rectangular hole is made, into which a rectangular frame is inserted from sections of the proposed profile, thereby forming an opening 7, limited by smooth walls painting ribs 4 with side shelves 2 and horizontal short walls 11 facing the hatch, into which the hatch is installed (not shown). Adjacent to the side shelf 2 is a horizontal rib 8, which in turn is adjacent to the mounting shelf 3. The corrugated walls of the mounting, painting and horizontal ribs form a cavity for filling with putty 9. On the internal surfaces of the mounting, painting and horizontal ribs facing each other there are grooves , which, due to an increase in the contact surface area of the ribs with the putty, and an increase in the strength under shear forces between the putty and the surface of the ribs, increases the strength of fastening the profile to the ends of the gypsum board.

Chambers of rectangular cross-section can be elongated vertically, with the internal horizontal wall common between the chambers and the external (horizontal) walls parallel to the internal wall being shorter than the external vertical walls. This implementation will further increase the strength of the profile box, and, accordingly, the entire structure, due to the increased profile depth.

The side shelf can be designed as a continuation of (one) long vertical wall, and the end of the side shelf can serve as a painting rib. This implementation will further increase the strength of the profile box due to the absence of a transition between the painting shelf and the rib.

The manufacture of an opening for a hatch in the ceiling is described, but it is clear to a specialist that in the same way it is possible to arrange an opening in a vertical or inclined wall and the signs “vertical” or “horizontal” describe the relative orientation of the profile parts, but do not refer to an arbitrarily mounted profile.

The technical result - increasing the strength and reliability of fastening the profile to the ends of the window in a gypsum plasterboard coating is achieved by the presence of mounting and painting ribs connected by a horizontal rib, together with grooves that form a cavity for putty, covering and connecting the end of the gypsum plasterboard and the profile.

Industrial applicability. The proposed profile for edging openings can be manufactured using known technologies.
