Abstract

FIELD: construction.

SUBSTANCE: door unit comprises a steel frame of a door opening made by means of bending or stamping, which forms a seat for a door frame made of two parts of sheet steel by means of bending or stamping and with the possibility to install an armour, to locate a filler and decorative finishing outside without additional fixtures, door hinges. The frame of the door opening may be made both from separate steel blanks by the method of their pairwise bending, by number of sides to form corners between shelves, on one of which along the entire perimetre there are distancing bosses (10) welded with a threaded hole at the end, and on the opposite shelf there are holes arranged for pulling of coupling bolts (11) to them, which at the corners pass through applied L-shaped joint plates, and in a solid-stamped version of half-frames without such, but with preservation of all holes for passage of coupling bolts to bosses, making it possible to clamp a wall with shelves-cases and to simultaneously form a door seat to product a slot along the entire perimetre of its adjacency for laying of a sealing element (14). The door being hollow comprises two panels (16, 18) of sheet steel, having board bends, on one the boards are higher than on the other one, and their top is bent with a gap inside for matching with three boards of the second panel inside with the help of wooden racks or other spacers along the perimetre. For possible installation of the armour or a decorative finish (24), the door ridges are clamped and bent inside to the plane of the frame to form a case slot, besides, bushings of suspended joints are rigidly fixed to them, and their axes (12) are fixed rigidly to the door seat on the frame along the fold with high anti-engagement leg (13), which is stretched along the hinge bushing height and is at the distance of the minimum gap from it.

EFFECT: simplified design and improved break-in resistance of the door unit.

Description

The invention relates to the construction and, in particular, to doors with door blocks used in the construction of residential and office buildings, as well as a replacement option for not entirely reliable or outdated structures.

The closest analogue is essentially a door block according to the utility model RU 9625 U1. The door unit contains a forming socket for sheet steel made of two parts by bending or stamping and with the possibility of installing armor, placing filler and decorative finish without additional door frame fastenings, a steel frame of the doorway by bending or stamping, door hinges. In this decision, there is no focus on a combination of design options, including design ones, i.e. adaptive premises prompted by the types of doorways.

An alternative is a simpler design solution that allows you to use a combination of the entire range of designs by type (type) of doorways.

This technical result is achieved in that the door unit comprises a forming socket for sheet steel made of two parts by bending or stamping and with the possibility of installing armor, placing filler and decorative finish without additional door frame fastenings, a steel frame of the doorway by bending or stamping, door hinges. The frame of the doorway can be made, as from separate steel billets, by bending in pairs, according to the number of sides with the formation of angles between the shelves, on one of which distance bosses with a threaded hole on the end are welded around the perimeter, and holes for passing the tie bars are located on the opposite shelf bolts to them, which in the corners pass through the superimposed l-shaped butt plates, and in the fully-stamped version, half-frames without those, but with all the holes for the passage to the bosses of the coupling bolts preserved , which make it possible to squeeze the wall with shelves-platbands and at the same time form a door nest with a groove around the entire perimeter of its adjoining groove for laying the sealing element, at the same time the door itself, being hollow, consists of two sheet steel panels having side bends, on one side higher than the other and their top is wrapped with a clearance inward to align with the three sides of the second panel from the inside using wooden battens or other spacers around the perimeter, with the aim of possibly installing armor or decorative trim the door crests They are bent inward to the plane of the box, forming a penny groove, in addition, hinges (canopies) bushes are rigidly attached to them, and their axes with a high anti-traverse leg, which is extended to the height of the hinge sleeve and spaced from the door, are rigidly fixed along the alignment. her with a minimum gap.

Based on the fact that the door block should help maintain comfortable conditions in the room and at the same time serve as an obstacle to unwanted entry, its design during the assembly of the frame provides for the formation of a groove for laying the sealing element around the entire perimeter of the junction of the door panel, and hinges (hinges canopies) are pre-protected from being hooked by a breaking tool with a high deposited leg. In addition, it is possible to vary the dimensions of the shelves of the frame of the opening and their angles, obtaining both different spacing of the door socket in the opening, and trapezoidal shelves descending to the door socket. The external shelves of the door shield make up a sad groove due to the folding, both for laying additional armor and for installing decorative panels.

The frame elements of the doorway can be made of sheet steel δ ÷ 3.4 (mm) in three versions: this is the production of two semi-frames by stamping, which is more suitable for mass production, or by bending paired oncoming panels. On the sides of the opening with the use of l-shaped butt plates during assembly at the corners and or the same, but with the control assembly. These panels are welded together at junctions from the inside, getting two half-frames similar to stamped ones.

The door for such a frame is made of two panels of sheet steel δ ÷ 2 mm. The main panel of this door has four sides along the contour, three of which (side and top) are higher than the bottom, their upper edges are wrapped with a gap for the entrance of the sides of another panel with three sides. After that, with the help of spacers, they are connected, crimped and bent, forming a pencil groove for the subsequent decoration of the shield.

But the frame of the door block itself is a kind of channel, the back of which is made up of two panels having a special profile and facing the inside of the aisle.

Each of the two half-frames has a platband shelf (instead of side channels of the channel) with an angle of less than 90 ° and a half back with bends of a certain profile. On one half-frame, remote bosses are welded with a threaded hole, and on the other there are holes for passing the coupling bolts to them.

Therefore, when laying half-frames on both sides of the wall and fastening them with tie bolts, a connection to the wall occurs with the simultaneous formation of a door socket.

The proposed door block can be adapted to different types of openings, for example, when changing a wooden block, you should initially measure the dimensions of the jamb in place outside. Then make the frame of the doorway 15-20 mm smaller in height and width. When all the calculations have been completed and the unit has been made, it is enough to carefully remove the wooden jamb with the door, and without closing it in the opening, without smoothing the irregularities, without applying the solution, you can easily install the panels with half-frames, pulling them with bolts to the remote bosses. Shelves-platbands so envelop the wall that nothing needs to be repaired. The main thing is that the lower side of the block frame, which does not have platbands, rests on the floor (standing on the floor).

Such a door block does not need additional fastenings, including with the use of dowels. And in agreement with the customer, you can vary, both by the location of the door socket and the corners of the shelves, calculating their trapezoidal shape, forming as if narrowing to the door socket. Even if one of the vertical sides of the frame does not have a wall coverage because it adjoins the plane, the absence of platbands will not be able to especially affect the rigidity of its fastening in the opening. The rest of the parties will cope with the task.

The invention is illustrated by drawings, which depict on:

Fig. 16 is a sectional view of a door unit assembly with a wall covering with shelves for half frames.

The frame of the doorway 6; 7 is made of sheet steel δ-3; 4 mm and can be made as a method of bending from eight panels, assembled in four in the form of two half-frames: internal and external or from two solid half-frames by stamping. In the latter case, there is no need for L-shaped butt plates - 15. You can also do without them, if at the corners separate panels at the junction point are connected by electric welding in one monolithic half-frame. Figure 1, 2, 3, 4 shows the cutting elements (panels) of the frame. Figure 1; 2 display the top of the frame, i.e. two opposite parts. So the bottom is identical to the top, but without shelves - 3. The bending lines are 1 (those), and the stroke of the line is 2 (vice versa). Between the lines of the bends marked sections (future shelves) - 3, 4, 5, 6, 7, 8. The same thing in figure 3, 4.

Figs. 8, 9 give a complete picture of the transmission of certain profiles to these panels after bending and their relative position in assembled form. On the shelf - 5, a protective leg - 13 is welded, covering the canopy sleeve - 25. On the inside of the shelf - 5, a remote boss - 10 is cut in section with a screw bolt - 11. A protective leg - 13 is welded on the shelf of the rigidly fixed axis - 12. A groove is formed between shelves 8 and 6 and a -14 seal is inserted into it; (Fig.9) shows the location of the decorative panel - 24 on the door panel. In Fig.6 is a view of the frame of the doorway from the outside, in Fig.7 (also) an inside view. This is what the frame of the doorway looks like after assembly from separate panels. In Fig.6, the axis of the awnings - 12 and the protective leg - 13 are indicated.

In Fig.7 marked l-shaped docking plate - 15 and holes - 9 under the coupling bolts. If half frames are monolithic, i.e. stamped, then in the butt l-shaped plates - 15 there is no need.

It is worth noting that in some cases, the bosses fastening - 10 and the location of the holes - 9, as well as the l-shaped butt plates - 15 can also be opposite.

Figure 5 gives an idea of the ability to vary the size of the shelves and the angles between them when making design options.

The door (door shield) is made of two parts of sheet steel δ-2 mm (Fig. 10-12). In Fig. 10, a small panel - 16 doors with a designated line of bends - 17, for the formation of sides. In Fig.12 the main panel is 18 doors with the marking of the bending lines - 19 (formation of the sides) and the lines - 20 of the inversion of the edges of the sides for the subsequent coverage of the sides of the small panel - 16. Figure 11 shows the sequential formation of the door shield. From the beginning, a small panel - 16 is inserted into the main panel - 18, then, lifting it, enter the edges of the sides - 17 into the inside of the wrapped boards - 32 of the main panel - 18, insert wooden spacers between them. After the crests of the sides - 32 squeeze and grab - 22 by electric welding (Fig. 13), bend inward, forming a sad groove - 23, for laying the decorative panel - 24 (Fig. 14). Fig. 15 shows a layout of wooden struts inside a door panel. Their installation should begin with the spacer - 26 moving to the top of the shield, then install the left spacer and the right - 21 with the stops - 28. Next, install the spacers - 27 and 30, then the stops - 31 and the spacer - 29, and after fully equipped the lower bent board - 32 (Fig.14) to return to the place and grab the electric welding. On Fig shows the door panel assembly with a decorative panel - 24 and welded bushings - 25 for a canopy door. Fig. 16 is a sectional view of a door assembly assembled with a wall covering shelves of half frames.
