Installation of iron entrance doors: instructions for use

As a rule, the entrance door is installed at the initial stage of repair in the apartment. Installation is usually entrusted to the company that installs the door, or install it yourself.

In this article we will describe how to install using our own resources. This is quite a responsible process, as the door should serve for a long time, it is easy to open and close.

It is very important to prevent serious errors in the installation process. This instruction is useful to those who are going to simply monitor the progress of work of installers.

Work on dismantling the old door

Installation begins with the dismantling of all structural elements of the old door. Dismantling work starts with the removal of the blade from the box.

In a situation when collapsible hinges are operated (see. Hinges for metal doors - the nuances of choice), it should open at an angle of more than 90 degrees, and then with the help of scrap, go up until it leaves the hinges. If the canvas is mounted on one-piece hinges, then it can be unscrewed using a screwdriver.

Before installation (see Installation of entrance doors), first of all, you will need to free the door from all elements of the old design.

Next is directly dismantling the box. If the box is made of bars, you must first unscrew or remove the anchor, nails, and then cut the side racks in the middle of the bar. Then they need to tear a crowbar.

Dismantling the metal box is more complicated. If that is fixed by welding, then the grinder will be needed to cut the fastening rods.

After the opening is cleared, it is necessary to knock out pieces of mortar and plaster that interfere with the installation with a hammer, and also remove all nails and pieces of heat and sound insulation.

Mount

The way in which the box will be mounted depends on the level relative to the opening on which the door is installed:

Mounting method number one

The most common option is to install the entrance iron door (see How to install the entrance door yourself) - a mount that uses mounting plates (on the side racks of the box there are three protruding plates).

In this case, the face of the canvas passes in the same plane with the wall, since The mounting plates are applied to the edges of the opening from the side of the dwelling. With the help of metal rods, driven into the holes of the plates, the box is attached to the wall. The rods after being hammered into the wall, welded, or riveted.

Anchor bolts can be a replacement for steel bars. In this case, it is recommended to provide a technological gap from the wall to the box in the amount of 10-20 mm on both sides.

Mounting method number two

This method is used if the installation of an iron entrance door involves drowning it in the opening. Since the web is recessed inwards, installation of the mounting plates along the edge of the opening is not possible. This method can be used only when the wall thickness is not less than 15 cm thick, since it can be pulled out of the wall during burglary.

Fastening is carried out through finished or drilled holes in the box. If they are already available, the box can be attached using anchor bolts. Bolts are covered with plastic plugs under the corresponding color of the box.

In the case when the holes in the profile were not provided, they are drilled, and then metal rods are driven into the wall, which are welded to the profile. Welding is carried out on the inner wall of the profile. The gap should be 5-15 millimeters on each side.

Depending on the type of opening, combinations of both methods are allowed. Bolts for fastening should be selected about 12 to 15 millimeters thick and from 100-150 mm long.

Proceed to install the door

So:

1. Before you install it, you will need to firmly fix the box in the opening. We will need wedges that will be slightly larger than the gap between the box and the opening. Scoring wedges in the lower and upper parts of the racks, you need to fix the box, not forgetting about the gaps from the walls.
2. Alignment must be done from the rack to which the hinges are attached. Using a plumb or level you need to check the vertical position of the rack.
3. For subsequent work will need electric drill and hammer drill.It is necessary to drill holes in diameters of about 15 millimeters to a depth of 100-200 mm in the wall through the lugs. It is necessary to hammer pins in the received openings. After this, the level is checked again.
4. If done correctly, you can weld the pins to the mounting plates by welding. Then you can hang the canvas, brushing the hinges and putting small balls in them. The remaining grease must be carefully removed.
5. Next, we begin the alignment of the side stand on the side where the keyhole is located (see Replacing locks in a metal door - as the masters do). At the same time shifting the rack, and opening, we create a uniform clearance from the door to the side rack. Now, as well as the previous rack, we fix it in the opening.
6. Installation ends brewing rods. It is recommended to brew the rods only when it will be clear that the web closes / opens easily, without touching the box. If you can not apply welding, you need to rivet the rods with a hammer. You need to be careful: a wrong blow can spoil its geometry.
7. Following the completion of the installation, you need to fill the gap between the box and the wall with foam. In order not to smear the box, from the side of the face it is necessary to impose paint tape over the entire perimeter.

   The doorway is reasonably moistened to improve foam adhesion. On zapenivaniyu it should be quite enough one cylinder for the entire perimeter of the opening. It is more convenient to use foam cylinders installed in special pistols. With this approach, it is possible to save material more economically due to accurate dosing of foam supply.

8. A day later, after the drying of the mounting foam, you need to plaster the mounting lugs and another space between the opening and the box (see also How to insulate an iron front door).

The installation of iron doors is a complex technological process that requires serious professional skills. If self-confidence is not enough, it is better to use the service of professional installers.
