Description

The invention relates to the field of construction, namely to the manufacture of doorways and the installation of doors. The invention can be used in the manufacture of building structures made of concrete or other poured material.

A known method of mounting a window and door frame in buildings, characterized in that in the masonry being constructed, a profile is installed that is mounted along the outline of the opening, then the door and window frames are installed and fixed. The profile consists of several elements that are mounted in place (Germany, application No. 4001517 from 01/19/1990, class E06B 1/02).

The disadvantage is the complexity of the installation, due to the fact that the profile, consisting of several elements, is mounted in place.

There is a method of attaching a door or gate box to the wall of an opening of a building, including mounting a door frame. This method also includes the manufacture of fixing elements on the surface of the box directly from the box material and subsequent fixation of the box. At the same time, grooves are made for the fixing elements on the surface of the opening (RF patent No. 2131507 of 10.30.1998 according to class Е06В 1/00).

The disadvantage of this method is the weakening of the bearing capacity of the wall due to the manufacture of grooves for the fixing elements, the complexity of installing the door frame, its special revision.

The existing house-building practice involves the installation of simple wooden (from chipboard, MDF, hardboard, etc.) entrance doors when the house is commissioned, followed by their replacement with burglar-resistant, for example, metal doors. Due to the difference in installation dimensions and methods of fastening simple wooden and burglar-proof metal doors, the openings undergo such a change (expansion, making holes and recesses, laying reinforcement, etc.), which leads to a weakening of the bearing capacity of the wall and requires a lot of labor. In addition, when replacing a metal door during operation, labor-intensive operations are carried out to dismantle the box, rework the opening for installing the box of the new door, and installing a new box. In this case, further weakening of the bearing capacity of the wall occurs. And so with every door replacement.

The technical problems to which the claimed technical solution is directed are the possibility of manufacturing a doorway that allows the installation and replacement of both a simple wooden and burglar-proof metal door without finalizing the opening and dismantling the fastening in the opening, the ability to fine-tune the installation of the box, strengthening the opening during its manufacture during concrete pouring, the absence of weakening of the bearing capacity of the wall due to the refusal to finalize the opening when installing the door.

Technical problems are solved by the fact that in the method of manufacturing a doorway, including pouring concrete from an iron reinforcement structure, according to the invention, during the manufacture of a building element in the place of the doorway being manufactured, an integral steel box (false box) with fastening elements, mainly brackets, is installed on one-piece joints, and after the building element is ready, the door frame is attached to the installation box by means of an adjustable detachable connection.

The method is implemented as follows.

Figure 1 shows the mounting steel box (false box) in the doorway of the building element.

Figure 2 shows the installation of a wooden door in the opening with a mounting steel box (false box).

Figure 3 shows the installation of a metal door in the opening with a mounting steel box (false box).

1 - building element with a doorway (wall, panel, etc.);

2 - mounting steel box;

3 - fastening elements of the false box to the door frame;

4 - adjusting grooves in a false box;

5 - a box of a wooden door;

6 - a cloth of a wooden door;

7 - platbands;

8 - a box of a metal door;

9 - sheet metal door 4

10 - detachable connection box with a false box;

11 - one-piece fastening of the false box in the opening.

According to the method, when performing a doorway in the manufacturing process of a building element 1, an assembly steel box 2 (hereinafter referred to as a false box) is installed in the place of the manufactured opening on one-piece fasteners (connections) 11. The false box 2 has fastening elements to the door frame of a simple (for example, wooden) or burglar-resistant (for example, metal) door. The door is installed by attaching the box 5 of the wooden door 6 or the box 8 of the metal door 9 to the fastening elements (brackets) 3 of the false box 2 to the detachable connection 10. The detachable connection 10 can be made adjustable, for example, with the adjustment grooves 4 in the brackets 3 for precise adjustment of the installation box. False box 2 and mounting clearances can be closed with platbands 7.

The method is applicable for making openings for internal doors (entrance doors to apartments) and external (entrance to a building) doors.

The proposed method eliminates the need for low-labor-intensive labor to change the opening with modern high-performance construction methods (panel and / or monolithic housing construction). Eliminates the weakening of the bearing capacity of the wall due to the rejection of modifications to the opening. Provides the ability to install both wooden and metal doors without modifying the opening, including replacing a metal door with another during operation, provides the ability to accurately adjust the installation of the box, the ability to replace the door without dismantling the fastening in the opening and finalizing the opening, strengthening (reinforcing) the opening false box.

Claims (1)

A method of manufacturing a doorway, including pouring a mortar of elements from iron reinforcement, characterized in that during the manufacture of the building element in place of the manufactured doorway, an assembly steel box is installed on one-piece joints - a false box with fastening elements, mainly brackets, to the door frame to which through an adjustable detachable connection, the door frame is attached.
