As iron stove impose bricks with their hands

Metal furnace quite often set in small private homes or adjoining buildings, where there is insufficient space for the massive brick buildings of this type.This oven has many positive qualities, but it is not able to retain heat for a long time is the same as a real brick.Therefore often arises the question of how to impose the iron furnace bricks with their hands and thereby achieve greater heat, but - not increase too its size.

carry out this work on their own is not difficult, if you have basic skills in masonry brick and prepare in advance all the necessary tools and building materials.


Of the tools and devices needed for the work:

Tools that are required for a brick for lining furnaces

tools that will be needed for the furnace brick for lining

1. Trowel for laying solution and collection of surplus after setting bricks into place.

2. Hammer with kirochka need to separate the desired part of the whole brick.

3. Fancy need for refining welds.

4. Cord prichalku used to control the evenness of masonry horizontal rows and angles.

5. poryadovkoy, which includes:

  • special rail that supports the evenness of masonry throughout the building height;
  • holder that fixes the rail;
  • wedge raises certain ale nt cl adki to the desired level .

6. Plumb provides control over the structure of the upright.

7. A building shall be verified level of evenness of horizontal rows.

8. Rule in this case will serve as a stand under construction level at check the evenness of the walls masonry on against each other.

9. Shovel need for mixing solution.

10. capacity for mixing solution.


By the choice of material should be approached with the utmost responsibility, if you want the oven to work efficiently and without interruption long enough.

1. Brick ovens for any need to choose high quality with significant fire resistance properties.It should be bodied, i.e. have no voids in its structure.You can acquire material having on the outer side of the relief pattern, or perfectly smooth option.Sometimes relief bricks leads to the laying of decorative adornment of any room.

Red burnt brick - what is required for furnace linings

Red burnt brick - what is required for furnace linings

number of bricks is calculated based on the size of the metal furnace and additional space around it , which it is planned to expand.In addition, it is necessary to take into account the foundation under the stove, which shall consist of one or two rows of solid masonry.

If oven be surrounded by cushioning and top, as well as the output brick chimney is to calculate these parameters.

also should consider how best to put a brick - install it on a narrow face (it will be more economical in terms of material consumption, but will negatively affect the work efficiency of the stove) or on the wide side.

If you make payment rough, without accounting thickness of seams, the original data will be the total surface area and the area of ​​the proposed laying of one side of the brick.Further steps are simple - the division of the first magnitude to a second and give the right amount of material in pieces.When calculating the exact , accounted for more and the thickness of the horizontal and vertical joints.But at the same time we should not forget to create a "reserve" 5 - 10%.

2. For quality masonry can not do, which will not be without the correct solution to crack when dry and in the future, with a strong warm-up brick wall.

If you do not have experience of drawing up a clay solution , it is better to use ready-made dry mixture of heat-resistant

If you do not have experience of drawing up a clay solution, it is better to use ready-made dry mixture of refractory

easiest to use ready-made compositions for refractory construction masonry stoves sold in specialty stores in the form of dry mixtures.They already have all the necessary components for high-quality performance and safety of masonry in extreme temperature conditions. ss percent receptacle achitelno simplified - most importantly, mix a solution of the finished mixture in the desired consistency in accordance with the instructions attached to it.

can proceed in another way, by making a traditional solution based on clay.

However, you must remember that this is a complicated process, as the clay must have a certain fat and mixture - optimal proportions.To do this, carry out tests of the kneaded and dried several different variants of the solution, which is made up of different parts of clay and sand.Only after such an experiment, and careful evaluation of the samples will be possible to make the right choice.

can say that the preparation of such mixtures - is an art, whose secrets are stored furnace masters.Such solutions are needed for laying the brick kilns where passes through the channels the smoke and gases emitted during the combustion of fuel, so the joints between the bricks should be extremely reliable , and good clay solution is able to provide a seal.But to impose metal furnace, it will be enough to take advantage of the finished dry mixture.

3. In addition to these basic materials needed to be a sheet of heat-resistant and waterproofing material, which is placed under the base of the furnace.As it is well suited roofing material.

4. If you plan to complete closure of the metal furnace, including a top of the brick vault, may need metal profiles (corners or strips) for the jumper, which will be conducted masonry.

Pre-masonry facing walls

When installing metal furnace for it should be prepared in advance hard nonflammable base, so in most cases the platform for its plate brick will be ready.If the base does not meet the requirements, but later decided to make a liner some time after the installation of stoves, then have to dismantle the chimney to to the period of preparatory work remove metal from the furnace where it is installed.This proce ss etc. gadfly to carefully prepare ploshadka.

  • If the floor is concrete and is strong enough, then the place of installation of the furnace and the future is laid masonry waterproofing material - roofing .roofing sheet should be 100 ÷ 150 mm wider area basis.

- When the base is ready, he will be lining the edges of the metal furnace, so size should be accordingly.

- The basis for setting spread in one or two solid number and allowed to dry.complete solidification of the solution time, you can learn from the information on the packaging of masonry mixture.

As a basis necessarily fit into one or two continuous series

- Once laid out the foundation attains the necessary strength, the oven is set in place, and it can be directly connected to the chimney.

- In the corners of the foundations exactly vertically mounted four bar, which will have to be leveled during laying.

Installed vertical bars will be a good help for the smooth masonry

  • In the case where wooden floor and reliable , can work carried out in the same way as on the concrete base, but it is better to remove some of the boards and makea strong foundation.

- When the boards are removed, in the soil underground arrange a small pit for strip foundation - its depth can vary from 30 to 50 cm, this option will depend on the height constructed of brick walls..It must be located in the place where the plans set facing the outer wall of the furnace.

- The bottom of the pit is strengthened pillows of sand and rubble. then to install the formwork and reinforcement cage.

- Further, concrete poured into the excavation (typically - at a ratio of sand and cement 3: 1) and allowed to completely set.

- After foundation tightly adhered, removed 120 ÷ 150 mm of soil from the site within it, this place is filled t compacted gravel and laid reinforcing mesh.

- then this area is filled with concrete solution of 50 ÷ 70 mm thick, leveled and left to curing.

Poured concrete foundation for the further furnace installation

poured concrete foundation for

further furnace installation at this site and will be laid the foundation of brick.When using this technology only one of a number of solid masonry.But all the waterproofing material still need to lay on the ground.

This foundation is necessary in the event that the furnace wall will be posted to the ceiling, and chimney will also be built of brick.If the walls will be built only on the height of the furnace, and the floor beneath it reliable enough , the foundation is not required.

  • When the device platform for the installation of the furnace and facing the wall, you need to take into account that it should be on the perimeter 60 - 80 mm larger than the structure of the future.

  • Between the walls of the metal stoves and masonry sure to leave a gap of 100 or even 120 millimeters - it will be a good air gap and allow for a longerterm to keep the oven hot.

What still should consider before laying

Turning to the plate of the iron hull furnace bricks, it is necessary to take into account some of the nuances that can make it easier work and provide effective safe operation of the heater.

  • Any furnace, installed in a wooden house or a wall built of inflammable material must be separated heat-resistant insulation.

insulation can be made of asbestos plates, Isover and other fire protection materials.It is better if such an insulating screen is made even in the two layers, as shown in the photograph.

Dual heat- shield to reliably protect the wall from the fire,

Dual heat-shield reliably protects the wall from the fire

In addition, the heater, as well as the chimney pipe should be away from the wall at a distance of not less than 200 mm.

  • For 25 ÷ 30 minutes before the start of the brick masonry, it is recommended to drop into the cool water.This proce ss etc. gadfly to harden bricks and to its porous surface does not dry immediately put the solution between the blocks, drawing from it liquid.
Pre- soaking the bricks will make the masonry particularly strong

presoaking brick masonry make highly durable

If solution will dry naturally way, the materials will provided good grip and masonry will strong enough.

  • It is very important to carry out masonry poryadovo , not from multiple rows at once - this can disrupt the entire work order, and she got sloppy.
  • folded 2 - 3 rows, you must immediately carry out "unravel" the seams until solution remains moist and pliable.Through this process, you should immediately remove the excess spoke masonry mortar.

Refining seams "jointing»

  • Making clutch "quarter-brick", ie setting it on the brink of a narrow, somewhat more complicated than putting in a "half-brick".If, however, the goals of saving was elected precisely such an option, when laying need to conduct very careful continuous monitoring of vertical and horizontal plane.

Clutches of "quarter-brick" will require special care to comply with the vertical and horizontal walls

process for lining the metal furnace brick

  • between installed vertically bars, height from floor to ceiling tensioned perfectly horizontal cord.In the process of lifting masonry, move higher and the benchmark.On this level spanned beacons aligned each row.
  • width of the vertical joints between the bricks is generally from 5 to 7 mm, the horizontal of 8 to 10 mm.
  • very important for ventilation, active receipt of heat in the room created by convection currents in each of the rows or through number leaving a small opening.Sometimes masonry, which draw up the iron furnace, is "lattice" with numerous holes.

«latticed" brickwork around the bathhouse furnace

Thus, for example, put a brick at an electrode bath furnace to heat quickly warms the room and, while , for by the thermal inertia of the bricks not longercool down ourselves wall heater.

  • Laying the first row in the usual way, but it must be carried out perfectly, as sets the direction of the entire wall.
  • After laying and pressing the first row of bricks, mortar surplus should immediately collect.If the brick is installed it is difficult because of the excess of the solution, he incited a rubber mallet.

  • Raising masonry, and reached the door ash, and then the furnace, it is very important to pay attention to the side lays out the window, where the loop.Stacking each of the bricks next to the doors, it is necessary to check how free they are opened.
Brickwork should not interfere with the free opening of the door

Masonry should not interfere with the free opening of doors

  • Laying make up the different levels of the oven.Sometimes it end plate on the level or even dress her chimney.However, in the latter case, chimney metal pipe must be collected in a very robust design and the most resistant materials, so how to get to her after shutdown does not turn .
Make sure the vents are left around the chimney

sure to leave the ventilation holes around the chimney

The brickwork around the chimney make sure several vents.

  • masonry must be obtained clean and tidy, so , folded several rows, it is necessary to clean off still not frozen solution, and its remnants scour damp cloth.

After completing masonry it must dry thoroughly, desirable - natural way, without heating.This lowers the likelihood that the mortar joints crack.
