How to build a rural fire wall, and what materials are used for a rural fire wall

A fire wall is a device that uses the smoke from the stove to heat the room through a hollow short wall made of vertical bricks, and similar to the ondol, it uses the heat generated by the stove to raise the indoor temperature in winter. Walls of fire have a long history in China. Everyone knows that the Northeast is a very cold place, so every household in the Northeast uses a kang to keep warm.

However, compared with the first kang, the heating of the fire wall is more three-dimensional to the indoor space, and the structure of the wall is also more demanding.

The construction method of the fire wall in the northeast is that the fire kang is connected with the wall, and the wall is made hollow, and the wall will be hot when the kang burns the fire, which has a good effect of keeping the cold warm. The fire wall is composed of three parts: the hearth, the fire wall and the chimney. The hearth can be located in the fire wall, or it can be set close to the fire wall to form a wall-connected stove.

The stove in the wall of fire is used for cooking, and the hot smoke is heated through the wall of fire. A fire wall can also double as a partition wall, but it is not allowed to be used as a load-bearing structure.

To put it simply, the wall is hollow, connected to the stove, and the hot air rises on the principle, and the heat generated by the stove is brought into the hollow layer of the wall.

and the thermal resistance of the wall material.

The value is relatively low, and the entire wall radiates heat into the room.

The fire kang is easy to burn by building a flue structure with smooth circulation.

The fire kang is mainly popular in ancient China in the Northwest Plateau, the Central Plains, the middle and lower reaches of the Yellow River, North China, Northeast China and other northern regions, and the cooking fire is used as a cold heating system (system) sleeping facility with heat energy.

The ondol heating system consists of three parts:

1. Stove with heat source.

The heat of the ondol** is a cooking stove that uses firewood (dried plants) and coal as fuel to make daily meals.

2. Heating and heat dissipation of the ondol.

It is a flue gas circulation setting built into the kang body and serves as a heating and sleeping platform with thermal effect. The main construction materials are adobe, machine-made bricks, and well-bonded earth or concrete. The key point is that the distribution of pyrotechnic airflow should be uniform and smooth, and the due degree of smoke retention should be maintained.

3. A chimney for exhausting smoke.

As a chimney for discharging ondol smoke, it is a flue gas discharge setting located in the wall at one end of the ondol.

The cement board material for rural fire wall is the best, and the advantage of cement board for fire wall is that it is thick, strong and durable. The temperature inside the fire wall is very high, and the cement board has very strong high temperature resistance, which can be used for many years without replacement. The rural fire wall is the wall where the ventilation of the kang or stove is connected to the wall.

The walls are made of hollow bricks, which allow for hot air. As long as the fire is lit, the room can be heated up quickly, it is very warm, and the cement board is economical and the cost is relatively low. The fire wall should have a certain heat storage capacity, and the masonry material should be solid clay bricks or other heat storage materials.

Presentation of the Rural Fire WallFire walls are commonly found in the north, especially in rural areas in the northeast, and are usually connected to fire kangs. By burning firewood, heat is supplied, and hot air flows and dissipates in the wall, so as to achieve the purpose of heating. This architectural structure has helped the Chinese to keep out the cold for 2,000 years, and now it is difficult to find the earliest fire wall dating back to the Han Dynasty, and a similar structure of the fire wall was found in the Chang'an site, which has a history of nearly 2,000 years.

In addition to the building structure of the fire wall, there is a building material that was also the key to keeping the ancients warm and cold, and that is adobe. As many people know, adobe houses can still be seen in rural areas. The use of adobe to build a house is not only because of the low cost, but more importantly, the adobe has good thermal insulation properties.

This keeps the heat in the house and doesn't dissipate too quickly.

Summary. Precautions for building walls 1, must ensure the temperature of construction Under normal circumstances, the height of the wall must be controlled below 1.8 meters. If the construction is carried out in rainy days, the height of the masonry wall must be controlled below 1.2 meters, and the consistency of the mortar must be controlled, otherwise the construction quality will be affected.

In addition, at the end of each day, it is necessary to put dry bricks on the surface of the wall or cover it with other coverings. This is to prevent the wall from being damaged.

Hello, I am honored to answer the sedan chair for you, the fire wall is built, first set up a return flue in the fire wall, and then build a hollow short wall with a thickness of bricks, a length of 2 meters, and a height of meters. Of course, inside the wall, remember to design a flower hole, single hole and other modes of smoke annihilation spine road. It is important to note that:

A wall of fire can be used as a wall of hyperostomy between the walls.

Precautions for building walls 1, must ensure the temperature of construction Under normal circumstances, the height of the wall must be controlled below 1.8 meters. If it is raining and the first work is carried out, then the height of the wall must be controlled below 1.2 meters, and the consistency of the mortar must be controlled, otherwise the construction quality will be affected. In addition, at the end of each day, it is necessary to put dry bricks on the surface of the wall or cover it with other coverings.

This is to prevent the wall from being damaged.

2. The mortar should be mixed and used immediately, and the mortar used for the wall should be approved to follow the principle of immediate mixing and immediate use, and the mixed mortar should be used up within five hours. If the temperature of the construction is higher than 30 degrees Celsius, the mortar will be used up within two hours. In addition, if you find that the mortar you are mixing has hardened, you should stop using it immediately, and if it is an overnight mortar, you should not use it.

Dear, hello, I am glad to answer for you how to build a rural fire wall The fire wall is a device that uses the smoke of the stove to heat the hollow short wall made of standing bricks, similar to the fire kang, and uses the heat generated by the stove to raise the indoor temperature in winter. Walls of fire have a long history in China. The fire wall is composed of three parts: the hearth, the fire wall and the chimney.

The furnace can be located in the body of the fire wall; It can also be set close to the fire wall to form a wall-connected stove. The fire wall is equipped with a winding flue, which is often built into a hollow short wall of thick bricks, high meters and long meters. The wall can be built into vertical holes, horizontal holes, single holes, flower holes and other forms of flues.

The hot flue gas flows in the wall for a long time, the heat storage time is long, the thermal efficiency is high, and the heat dissipation is uniform. The chimney is the smoke exhaust channel of the fire wall and should have sufficient height. The stove in the wall of fire is used for cooking, and the hot smoke is used to heat the fire through the wall of fire.

A fire wall can also double as a partition wall, but it is not allowed to be used as a load-bearing structure. To put it simply, the wall is hollow, connected to the stove, the principle of hot air rising, the heat generated by the stove is brought into the hollow layer of the wall, and the thermal resistance value of the wall material is relatively low, and the whole wall radiates heat to the room. Compared with the first Chang Kang, the heating of the fire wall is more three-dimensional to the indoor space, and the structure of the wall is also more demanding.

Therefore, the unreasonable indoor limb space, or the insufficient insulation of the external maintenance structure, and the inappropriate selection of fire wall materials will have an impact on the comfort of fire wall use.
