This is what the article will be about.

To protect your home from hacking, you must make the entrance to it as reliable as possible. So far, nothing has been thought out better than metal entrance doors, which are sometimes equipped with several locks, surveillance systems and alarms.

They are made of quality material that is very difficult to deform. But all these measures may be in vain if the installation rules are not followed.

After all, attackers can not touch the door itself, but simply pull it out of the opening along with the box. To avoid this, be sure to follow how the installation of your entrance door.

Preparation of the opening

If there is an old door in the doorway, it should be carefully dismantled. You can do it yourself, without waiting for installers.

So:

1. If it hangs on collapsible hinges, just open it wide, place a crowbar or other lever under the bottom end and lift the door leaf up so that it jumps off the hinges.

If the hinges are one-piece, unscrew the screws that hold the door in the box with a screwdriver or a simple screwdriver.

1. Empty box will be easy to dismantle if it is wooden. To do this, unscrew from it all the visible attachment - anchor or screws, pull the nails. If the box is firmly in the opening, then cut the side racks in the middle and tear them off with a scrap. After that, the upper and lower parts of the strapping are dismantled without problems.
2. To dismantle the metal box, fixed in the opening with the help of welding, you may need a Bulgarian. She cuts off all fasteners that can not be pulled out manually.

1. Dismantling the old, clean the gap from the foam, old heat and sound insulation and everything that may prevent the installation of a new one.

Ways of fixing the door frame

The metal box can be mounted in the opening in different ways:

• Through the holes in the profile box
• Using mounting plates

Fastening through the holes in the box profile

Installation rules for entry doors allow the box to be fastened in the first way only if the thickness of the opening is more than 15 centimeters, otherwise it is easy to pry the door out of the wall along with the box. In addition, when attaching the box through the mounting holes made in it, it is necessary to embed the entrance door inside the opening.

The fact is that if you install the box flush with the outer wall, the mounting holes will be only 4-5 cm from the wall surface, and the mount will be very unreliable. And if the wall is a monolithic concrete panel, then there is a risk when drilling holes for fasteners to stumble upon metal reinforcement, which is located in the panels at about the same depth.

Usually the holes are provided by manufacturers immediately, and complete with an entrance door are special long anchor bolts for fastening and decorative plugs in the color of the box.

If there are no such holes, they should be drilled at a distance of about 30 cm from each other. Subsequently, trimming fittings or steel rods with a length of at least 15 cm and a thickness of 12-15 mm, which are welded to the profile from the inside, are hammered through them into the slope of the doorway.

For reference. If for some reason the application of welding is impossible, the metal rods after the installation of the box can be riveted by striking a sledge hammer or a heavy hammer. In this case, you need to act carefully so as not to damage the box.

With this method of mounting on each side of the rack box should remain technological gaps 10-15 mm wide.

Fastening with mounting plates

The second mounting method is more common and reliable. If you know how to install a metal entrance door correctly, then you will look for doors whose box is equipped with mounting plates with ready-made mounting holes.

At each rack must be at least three. These plates allow you to install the door in the same plane with the outer wall, as they are facing the inside of the apartment and attached to the opening at a sufficient distance from the wall surface.

Such boxes are fixed to the walls in the same way as in the first case - with anchor bolts or steel rods, followed by welding. But the size of the technological gaps increase to 15-20 mm.

Council To provide even more reliable fastening, it is possible to combine both methods, using both mounting plates and openings in the box.

Door installation

As in the case with interior doors (see How to install an interior door), first installed in the opening box.

Of course, the correct installation of the entrance doors implies their careful alignment vertically and horizontally, so the box must first be fixed in the opening with wooden wedges in order to be able to adjust its position.

The following steps are as follows:

1. First of all, the rack with door hinges is aligned in two planes., what is used for a long level or plumb.

1. When this is done, holes are drilled in the opening through the mounting holes. perforator channels to the depth of the length of the anchors or pins.
2. After re-checking the level of the loop stand of the box is attached to the wall using the methods described above: screwing in anchors or blocking metal pins.
3. The next step is to hang the canvas on the pre-lubricated hinges. On the door should already be installed all the accessories - locks, handles, peephole.
4. Proper installation of entrance doors requires alignment and the second rack of the box. To do this, cover the door and, moving the rack, make sure that the gap between them is equal along the entire length and is 2-3 mm. After that, you can fix in the doorway and a mock stand, making sure that the door easily enters the box, and the lock closes without effort.
5. At the end of the installation, the doors need to be sealed with cement mortar or filled with gaps between the box and the wall, previously pasted over the box with masking tape so as not to stain it.
6. When the foam or solution is completely dry, you can proceed to the plastering slopes or lining them with decorative finishing materials.
7. From the outside, the entrance door is decorated with platbands.

European way of fixing doors

If you seriously wondered how to properly install the doors, then pay attention to the so-called European method of attachment. For him are made of external boxes of special profile, which tightly cover the opening on both sides. They are made to order, given the width of the doorway.

The free space formed between the box and the wall is filled with cement mortar, which includes special polymer additives that increase the strength of the solution. After it hardens, the wall with the box forms a monolithic structure that is almost indestructible.

As you can see, to install the front door requires good professional skills and special tools. Therefore, even with a great desire to save this work, you need to provide the experts to perform.
