The invention relates to the field of construction. prior art.

 Known methods of mounting the door in the opening: invention RU 2387778 dated 11/23/2005 "Method of fastening doorway boxes of interior doors", invention FR 2612560 A1, 09/23/1988 "Device for attaching a blind frame to the edges of the opening", invention DE 191 1433 A1, 14.09 .1972 "Turzarge", 15 utility model RU 62633 U1 12/27/2006 "The door frame mounted in the doorway of the wall", as well as utility model 15198 Ul RU 07.06.2000 "Anker".

Disclosure of the invention.

 0 The proposed method is designed for mounting doors with and without threshold; the box of which is made of wood, aluminum, plastic or other material.

 There is a method of fastening a door box in a wall opening using fixing elements connecting the box 1 to the edge of the wall opening 2 at which 5 screws are screwed directly into the ends of the opening or through dowels 3 and on these screws using mounting plates 4 that are screwed to the outer to the side of the box with fixing screws (screws) 5 fix the box, “putting” it on the screws by placing the head 6 on the end of the screw between the plate and the box in the slot in the 0 plate for fixing 7, the width of which is smaller than the size the head of the self-tapping screw and which starts from the edge of the plate or is part of the hole in the plate, the other part of which is larger than the size of the head of the self-tapping screw, which allows you to fix the plate screwed to the box on this self-tapping screw. In this case, the mounting plates screwed to the box are stationary.

5 The proposed method of mechanical fastening of door frames differs from the known method in the ability to move mounting plates along the box with loose fastening screws 5, by which the plates are screwed to the box. The plate moves along the box due to the elongated mounting holes (slots) 8 through which the plates 0 are screwed to the box. Mounting holes can be straight or indirect and with constant or variable width. The shape, configuration and location of the mounting holes can allow the mounting plate to be moved along the box with the loosened mounting screws to fasten the box in the opening, and in combination with the slot 5 for fixing to the plate, they should allow the box mounted in the opening to be loosened with fixing screws making adjustments during installation: adjusting the position of the box, the vestibule of the door leaf and the gap between the top of the door leaf and the box, with the plate moving along the box without jamming.

 On the side of the fastening to the door frame, the plate has a flat shape without protrusions, which allows the plate to slide freely on the box without jamming when the fastening screws are loosened in the direction of possible movement, even if there are grooves in the box at the place of screwing the plate, and also provides the necessary stability of the screw plate on the box under the action of a tearing force and a tearing moment on the plate in the direction from the box to the end of the opening with the box fixed in the opening, and accordingly not bhodimuyu mounting rigidity.

 In order to loosen or tighten the fastening self-tapping screw with the box fixed in the opening, the head of this self-tapping screw can have a hexagon or any other shape for the corresponding key, so that you can unscrew and tighten the self-tapping screw with a key in the space limited by the end face of the opening and the box.

 The ability to move the plate around the box during installation allows you to fix the box in a "low" opening when the box enters the opening, but the height of the opening does not allow you to lift the box up to "put on" the screws. In this case, the plates are moved along the box in a vertical or inclined direction to fix them on the heads of self-tapping screws screwed into the wall.

 Also, the ability to move the plate along the box during installation allows you to adjust the gap between the top of the door leaf and the box, the vestibule of the door leaf and the position of the box in the opening by shifting the boxes fixed in the opening in the vertical direction or in the direction perpendicular to the wall plane. This allows you to fix the box in the aperture with very high accuracy in the absence of the need for accurate marking of the mounting points of the plates to the box, which speeds up and simplifies installation.

 To increase the bending stiffness, the mounting plate may have a recess 9 in the place where the slot or hole with the slot is for fastening on the self-tapping screw screwed into the wall, so that the mounting holes are located outside this groove, while the depth of the groove should be sufficient so that the head of the self-tapping screw located between the plate and the box did not protrude beyond the plane of the plate from the side of the plate to the box and did not interfere with the movement of the plate along the box, even if the screw was screwed wall obliquely. If there are recesses in the plate, it is not necessary to make a recess in the box for the head of a self-tapping screw screwed into the wall, which is located between the box and the plate. Accordingly, the presence of a recess in the plate allows you to fasten the door not only with a wooden, but also with a solid aluminum frame, for example.

To avoid accidental displacement of the plate on the jamb during installation, for example with a heavy door, and to increase the reliability of fastening additionally, the fixing plate may have a hole or slot 10 located so that the locking screw (screw) screwed through this hole or slot into the box after making adjustments blocks the further possible movement of the plate along the box when the door is installed.

 The marking of the mounting points of the plates on the box is carried out by measuring and postponing distances either using a stamp that is put on the head of a self-tapping screw screwed into the wall or that is made on the head, and with which a fingerprint is obtained to determine the center position of the head of this self-tapping screw on the door frame jamb when the jamb is in contact with a stamp. The use of a stamp simplifies and makes the marking process clear.

 Adjustment of the lateral gap between the door leaf and the frame, as well as the fastening of a rigid closed box is performed by unscrewing or screwing self-tapping screws screwed into the wall. In contrast to the known methods in which a self-tapping screw is rotated behind a single head located at its end, the proposed method can use a special self-tapping screw (screw), characterized by the presence of a "skirt" (additional head) 11 located on the self-tapping rod, for example, in the form of a square or hexagonal nut for which a screw is turned with a key. The use of such a self-tapping screw allows you to screw and unscrew the self-tapping screw from the wall in the case when the mounting plate blocks the key from accessing the head at the end of the self-tapping screw. In this case, in order to screw or unscrew the self-tapping screw from the wall to the required size, it is not necessary to remove the box in order to free access to the self-tapping head located at its end, which speeds up and simplifies the adjustment. In addition, the use of the proposed self-tapping screw allows you to fix a rigid (non-bending) box with a threshold for example from aluminum, for example, if the slot for securing the self-tapping screw in the plate is part of the hole in the plate, since in this case, when fixing, the screw must be unscrewed from the wall so that its head fits into the hole with a slot for fixing, and the plate will not allow you to do this for the head located at the end of the screw.

 The proposed self-tapping screw differs from the anchor described in the utility model 15198 Ul RU by the presence of a “turnkey” head on its end or a head with a standard slot on which a box with a screwed mounting plate is fixed. Unlike the well-known anchor, the proposed non-standard self-tapping screw is screwed into the wall before fixing the box to this head located at its end, which allows you to use a screwdriver with a standard nozzle (bit) thereby speeding up and facilitating the operation.

With the horizontal position of the slot for fixing 7, the door block, fixed in a known manner in the opening, can fall out of the opening, since the horizontal slot for fixing in the plate does not block the movement of the fixed box in the horizontal direction, which can lead to the exit of the screw head from the slot for fixing and disconnecting the screw with a plate. To eliminate this possibility It is proposed that when the slot is horizontally located for fixing in the plate, a stopper is made, for example, in the form of a protrusion 12 in the slot for fixing, preventing the spontaneous exit of the self-tapping head from the slot for fixing.

 Mounting holes in the mounting plate are available.

 In the first embodiment, it is proposed to perform a metal mounting plate with a vertical slot for fixing the plate located in the recess and being part of the hole in the plate having two mounting holes for fixing the plate to the door frame which allows the box to be fixed in the opening by moving the plates along the box and adjusting the position of the box in the opening during installation: one vertical or inclined elongated mounting hole located in the lower part of the plate, the second L-shaped (corner voe) a mounting hole located in the upper part along the side and upper sides of the plate, and the angle in the corner hole may differ from ninety degrees and the side and upper sides of the L-shaped hole and the lower hole may not be straight, in particular the upper part of the corner hole may be arcuate, in addition, the plate may have a slot for fixing self-tapping screw in the upper part.

 In the second embodiment, it is proposed to perform a metal mounting plate with a vertical slot for fixing the plate located in the recess and being part of the hole in the plate having two mounting holes for fixing the plate to the door frame that only allow you to adjust the position of the box in the opening during installation: one vertical elongated mounting hole located in the lower part of the plate (in the particular case, this hole can be round), the second horizontal line or arc A different mounting hole is located in the upper part of the plate, and with a round lower mounting hole, the center of the arc of the arcuate mounting hole is in the center of the round mounting hole, in addition, the plate may have a slot for fixing self-tapping screw in the upper part.

In the third embodiment, it is proposed to perform a plate with a horizontal slot for fixing the plate located in the recess and starting from the edge of the plate and two vertical or inclined elongated mounting holes for fixing the plate to the door frame located in the upper and lower parts of the plate that allow the box to be fixed in the opening by moving the plates on the box and adjust the position of the box in the opening during installation; in addition, the plate may have a stopper in the slot for fixing in the form protrusion.

The technical result is:

1. High accuracy of mounting the box in the opening, which does not depend on the accuracy of the marking of the mounting points of the mounting plates on the box and does not depend on the parallelism of the axis of the self-tapping screw screwed into the wall of the opening plane in the wall and the floor plane, accelerating and simplifying the adjustment of the position of the box in the opening and the porch of the door leaf, as well as reducing the permissible height of the mounting opening in the wall due to the possibility of moving the plates along the box.

 2. An additional head on the rod of a self-tapping screw screwed into the wall is a stopper restricting the play (possible movement) in the connection of this self-tapping screw with the plate in the direction of the self-tapping axis, for example, when a groove passes under the head at the end of the self-tapping screw. The play is limited by the distance between the head at the end of the self-tapping screw, on which the box is mounted, and the additional head. Restriction of backlash simplifies the adjustment of the door during installation.

 3. The ability to adjust the gap between the blade and the box for any form of mounting plate (including if the plate blocks the key from accessing the head at the end of the self-tapping screw when the box is fixed in the opening) and the ability to mount interior doors with a threshold and a rigid box through the use of a self-tapping screw with a "skirt" (additional head) in the form of a nut.

 4. Due to the presence at the end of a self-tapping screw screwed into the wall with an additional head head with a standard slot, it is possible to use a screwdriver with a standard nozzle when screwing such screws into the wall before installing the box in the opening, which will expedite and facilitate operation.

 5. Sliding plate on the box without jamming, even if there are grooves in the box at the place of screwing in the box, as well as increased rigidity of fastening due to the stable position of the plate on the box under tearing moment due to the flat form of the protrusions of the plate on the side of the plate to the box.

 6. An increase in the rigidity of the mounting plate for bending and an increase in rigidity and fastening due to this, as well as the absence of the need to make a recess for the self-tapping head in the box and, accordingly, the possibility of mounting doors with a solid box due to the presence of a recess in the plate.

 7. An increase in the reliability of fastening due to the presence of an additional hole in the plate for the fixing self-tapping screw, the installation of which prevents accidental displacement of the plate along the box.

 8. The door unit fixed in the opening cannot accidentally fall out of the opening during installation and after the door is installed, which makes installation safe and reduces the risk of accidentally damaging the door unit during installation.

9. The installation of the door in the opening is divided into a sequence of simple operations for securing the door and making installation adjustments. The result of each of these operations remains unchanged during subsequent operations, while the sequence and content of all operations performed do not depend on the type of door, wall material, dimensions and configuration of the doorway. That is, a single standard door mounting technology is proposed, the use of which allows to simplify the installation, to achieve a consistently high quality of installation doors, including with little experience with the installers, as well as reduce training time in the preparation of installers.

The implementation of the invention.

 Mounting the box in the opening is as follows.

Self-tapping screws 3 are screwed into the lateral ends of the wall 2 opening, which are beacons defining on the hinge side the vertical position of the door box 1 in the wall plane. Using a stamp, which is put on the head of a self-tapping screw 3 screwed into the wall and giving an imprint indicating the position of the center of the head of this self-tapping screw on door frame 1, when the box contacts the stamp or by measuring distances, the mounting points of the mounting plates on the box are determined. Then the mounting plates 4 are screwed, having a recess 9 with a slot 7 to the box 1 through the elongated mounting holes in the plates 8 using fixing screws 5, the box is assembled and the box is fixed in the opening on the heads of the screws screwed into the wall 3, “putting on” the box with the screws screwed the plates on the screws or loosening the fixing screws 5 with a wrench and moving the plates 4 along the box 1. Then, when the fixing screws 5 are loosened on the side of the loops, the vertical hinge of the box 1 is adjusted in the plane perpendicular the wall gloss, tighten the loosened mounting screws with a key 5. Next, hang the door leaf and, loosening the screws 5, the fastening plates to the box on the handle side, move the jamb of the box 1 on the handle side (lock, latch) in the direction perpendicular to the wall plane, for adjustment the door of the door, tighten the loosened fastening screws with a key 5. Then, adjust the gap between the door leaf and the box by turning the key for the “skirt” 1 1 screws screwed into the wall 3 and eliminate the backlash in the connection of the screws screwed into the wall 3 with mounting plates 4 using spacer wedges that are inserted into the gap between the door frame and the ends of the opening. Next, this gap is filled with polyurethane foam or other material and install the casing.

 The proposed non-standard self-tapping screw can be made of steel using a technology similar to the technology for manufacturing standard self-tapping screws. The proposed metal mounting plates can be manufactured by sheet metal stamping or by any other method.
