Abstract

FIELD: construction.

SUBSTANCE: present invention relates to a method for arranging structures using drywall or similar sheets. The device for fastening drywall sheets in the form of a framing profile containing a vertical shelf connected to the upper side of the horizontal shelf, a putty unit consisting of two vertical shelves of different heights (low and high) with ribs adjacent to the lower side of the horizontal shelf, is characterized by the fact that the height of the vertical shelf is less than twice the height of any shelf of the putty unit, and there is a horizontal platform between the vertical shelf and the shelf of the putty unit closest to it.

EFFECT: increasing the reliability of the design, expanding the scope, increasing the speed of installation.

Description

Known "CEILING PROFILE" RU PM 182821 [1], including plasterboard sheets, which are attached to additional shelves of ceiling profiles using large self-tapping screws.

The disadvantage of the known method is the presence of profile parts protruding below the ceiling level and the visibility of the heads of the self-tapping screws.

Closest to the claimed technical solution is the "Device for installing a lamp" RU 195036 RPM [2], including including a profile for plasterboard, the profile contains a side wall, a putty assembly made with teeth.

The known method allows you to mount a plasterboard ceiling without protrusions.

The disadvantage of the known method is the low reliability of attaching a drywall sheet to the profile, a narrow scope, and low installation speed.

The technical result is an increase in the reliability of the design, an expansion of the scope, an increase in the speed of installation.

The technical result of the method is achieved in that: a method for fastening drywall sheets, including a framing profile that contains a vertical mounting shelf connected to the upper side of the horizontal shelf to form a right angle, a putty unit consisting of two vertical shelves of different heights with ribs adjacent to the lower side of the horizontal shelf, is characterized in that the vertical mounting shelf is attached to the load-bearing wall by means of screws, the load-bearing metal profile containing horizontal and vertical shelves is fixed in any known way, a sheet of drywall is attached to the horizontal shelf of the load-bearing profile from below with screws installed with their heads down, on the underside of the drywall and a continuous layer of putty is applied to the screw heads and to the putty unit.

The technical result of the device is achieved by the fact that the device for fastening drywall sheets in the form of a framing profile containing a vertical mounting shelf connected to the upper side of the horizontal shelf, a putty unit consisting of two vertical shelves of different heights (low and high) with ribs adjacent to the bottom side of the horizontal shelf, characterized by the fact that the height of the vertical mounting shelf is less than twice the height of any shelf of the putty unit, and there is a horizontal platform between the vertical shelf and the shelf of the putty unit closest to it.

The vertical flange of the frame profile can be pressed against the bearing wall with the same horizontal screws as the vertical flange of the bearing profile, which will further increase the reliability of fastening the structure to the bearing wall with the same number of screws.

The horizontal flange of the frame profile and the horizontal flange of the supporting profile can be fastened with vertical screws, which further increases the reliability of the structure.

You can use two horizontal sheets of drywall, the top sheet is placed between the underside of the carrier profile and the horizontal shelf of the framing profile, which further increases the reliability of the structure.

Putty can be used UNIFLOTT, which will further increase the reliability of the structure due to the stable properties of this putty.

Implementation of the invention:

In FIG. 1 shows a section of the assembled structure using a single sheet of drywall, FIG. 2 section of the structure when using two sheets of drywall, where:

1 - vertical shelf of the framing profile;

2 - horizontal shelf of the framing profile;

3 - low shelf unit for putty;

4 - high shelf unit for putty;

5 - vertical shelf of the carrier profile;

6 - horizontal shelf of the bearing profile;

7 - bearing wall;

8 - drywall sheet;

9 - horizontal screws fastening to the bearing wall;

10 - vertical drywall screws;

11 - caps of vertical screws;

12 - C-shaped retainer.;

13 - additional sheet of drywall;

14 - putty;

15 - screw for fastening horizontal profile shelves;

16 - horizontal platform between the vertical mounting shelf and the closest shelf of the putty unit.

The method is carried out as follows: a frame profile containing a vertical mounting shelf 1, a horizontal shelf 2, short 3 and long 4 shelves of the putty unit is attached to the load-bearing wall 7 by means of horizontal fastening screws 9, pressing the vertical mounting shelf to it. There is a horizontal platform 16 between the vertical mounting shelf and the closest shelf of the putty unit. The presence of such a platform allows you to securely and quickly fix the end part of the drywall sheet and the adjacent putty, since the load-bearing wall does not interfere with fixing. Making the height of the vertical mounting shelf less than twice the height of any shelf of the putty unit allows the vertical shelf to be optimally fixed to the load-bearing wall. The carrier profile can be attached to the building structure by any known method, including by pressing the vertical shelf 5 of the carrier profile against the carrier wall. A sheet of drywall 8 is attached to the horizontal shelf of the supporting profile 6 by means of vertical drywall screws 10, installed with caps 11 downwards. C-shaped clamps 12 are used to install pins (not shown) in them for precise installation of framing profile segments. The screw fastening the horizontal shelves of the profiles 15 additionally increases the reliability of the structure.

In the case of using two drywall sheets, an additional drywall sheet 13 is placed above the drywall sheet between the underside of the carrier profile and the horizontal flange of the framing profile and is fixed with vertical screws piercing both sheets of drywall.

The technical result is achieved by the fact that the vertical mounting shelf is attached directly to the wall, which increases the reliability of the structure. The expansion of the scope is achieved by obtaining the possibility of mounting any form of drywall sheets. An increase in the speed of installation is due to the possibility of simultaneous installation of the framing and supporting profiles.

Industrial applicability. The proposed method and device for fixing drywall sheets have been tested and can be successfully used for mounting ceilings and other structures.
