Doing their own hands the foundation for the fireplace in a wooden house - options for the construction and materials

Base by "decorative furnace" is mounted on various technologies.But if the fireplace is installed in a wooden house, the question of construction of the foundation under it requires special consideration, since many of the typical "projects", implemented in the other houses, in relation to this just does not fit.Before thoroughly acquainted with all the features of this work, you need to learn a set of rules relating to wooden buildings.

first

Fireplace NOT be installed directly on the floor or ceiling (with rare exceptions).A common mistake - "if I took care of fire safety measures, then nothing will happen."It's not so much the "combustibility" log, but in the strength of structural elements.Even a small fireplace, considering the materials used, is heavy.Does "deck" floor stand?

second

Compliance furnaces and space dimensions.Large fireplace, set in a small room, literally "dry" it.And what is fraught with reduced humidity, and not only for the health of households, but also for the life of things and materials that do not need to explain.For example, excessive shrinkage of wood entails its deformation, including a twist.On the joints in the joints (fixtures) is another type of impact is not the best way.

third

install a fireplace in the room, according to the principle "where it is more convenient and more beautiful" is impossible.He - a source of open flame, and even a small draft can trigger a fire seems to be entirely of burnt fuel.And if you go home?Therefore, there is a ban on the installation of "hearths" in front of the openings of windows and doors (because anybody does not become permanently fill the furnace with water, just in case).

fourth

Of all the types of fireplaces, given the flammability of wood for a wooden house is an acceptable option freestanding structure.But the feasibility of recommendations on arrangement adjoined to the wall or built into it "home" is highly questionable.Especially if it means "hands", so even without the proper experience.For example, how to assemble the chimney (which heats up) in a wooden wall?Questions and besides this is more than enough.

Features foundation installation

place

Something has already been said about this.It is necessary to clarify some points:

• Base under fireplace should be separate.Use for the purpose of the foundation of the house is prohibited.This is due to the difference in shrinkage stress and further constructions.Between
• foundation walls (buildings and furnaces), must be a clearance (a minimum 50 mm), which is filled with the granular mass (usually ASG).This provides a "decoupling" of bases, so the shrinkage of one does not affect the other.

Depth of

As with all types of foundations - taking into account the depth of soil freezing.In some cases, you can mount the base slab-type (if underground water come close to the surface, if the ground belongs to the category of problem - clay, sandstone and many others).

Rule about the depth can be ignored, if, for example, a large area of ​​the house, its foundations are well insulated, and in the structure of permanently resident owners (that is, it is heated all season).This ensures that the soil will not freeze as much under the building itself.It turns out that a few options, but the meaning is clear - to prevent the settling of the fireplace.

Footprint

It all sides must act for the furnace perimeter of not less than 50 mm.

foundation type

On this issue, many of the recommendations, that is to dwell.When choosing a particular project should focus on:

• mass of the fireplace;
• soil characteristics;
• convenience excavation (this is true for the already populated at home).

Belt fundameni

erect monolithic (for example, w / w) is defined by a massive fireplace.It is better to use this option - block.

Cheaper technology - fill in the prepared trench natural stone, gravel or pebbles major factions, and on top - bricklaying (figure explains all good).

Explanation: The level of the floor (1), masonry (2), shut-off waterproofing (3).

Foundations columnar

There are also a lot of nuances.How to choose the material?Probably, this option, as shown, is too expensive, and time consuming.

Upper: pos.5 - shut-off waterproofing.

Lower: Pos.3 - layer leveling;Pos.4 - Jumper w / w (stove),

more economical foundation - from metal pipes, into which is poured a solution.If it is raised in the course of building a house, you can use ready-made w / w blocks.As an overlap - reinforced concrete slab.

Brick monolith

That's one option, but given the complexity of the work and the cost of materials, not everyone will choose it.

Materials

few clarifications:

• for masonry mortar is recommended to cook.It is considered the best for the job.Preparation - dissolve lime in water at a ratio of 1 to 3. Prior to the mass of the desired consistency is adjusted by the addition of sand.
• All recessed portion of the base should be protected from liquids (vertical waterproofing).Most often it is by settling wash oily surfaces clay, diluted to a thick cream.As a rule, it is enough for the fireplace, especially if the foundation of the house - the ribbon monolith.
• Even during the preparation of the clay pit is placed on the bottom and compacted.So it turns out the first layer of waterproofing cut-off which protects the "cushion" under the brickwork.
