How to choose perforated bricks and small red bricks when building a house? What are the advantages

Red bricks are made of clay, shale, and gangue.

It is a sintered building brick made of raw materials, crushed, mixed and kneaded by manual or mechanical pressing, and fired by an oxidation flame at a temperature of about 900 degrees Celsius after drying, which was invented by the ancient Romans. In the process of firing, red bricks will destroy a large amount of arable land, consume coal, and at the same time exhaust gases will also cause pollution to the environment. The advantage of red brick is that it is relatively strong and durable, but the disadvantage is that it is more inconvenient in the transportation process, and there will be fractures.

Perforated bricks. It can be load-bearing, but its load-bearing capacity is weaker than that of a solid one, so most of the current frame or frame shear structures.

The exterior walls of the house are mostly made of hollow bricks, as a separation and waterproofing effect.

The application of perforated bricks reduces or eliminates the use of sintered clay bricks to a certain extent, which has a far-reaching impact on improving the environment and protecting land resources, and has very important social and economic significance. His biggest advantage is environmental protection, the production process energy consumption is particularly low, low energy consumption and harmful gas emissions are low, the natural cost is relatively low, the construction is particularly convenient, its appearance is equivalent to announcing the gradual demise of small red bricks. Concrete porous bricks have the characteristics of low energy consumption, soil saving and waste utilization, convenient construction, light body, high strength, good thermal insulation effect, durability, small shrinkage deformation, and regular appearance. In today's construction industry, it is slowly becoming a substitute for other brick products.

Under the vigorous promotion of use in many countries, it has become an irreplaceable product.

<> fill the wall. of the top, frame beams.

Below, the bricks are built diagonally. The purpose of this oblique masonry is to maintain a certain deformation capacity, and when the upper frame beam is stressed and deformed, the deformation of the oblique brick can occur and digest the deformation of the beam.

Which material is best depends on what structure you build. If you build a brick-concrete structure.

If the wall is to be load-bearing, then it must be made of solid red brick. If you build a frame structure.

Then the wall is not load-bearing, and perforated bricks can be used.

Perforated bricks are good, or small red bricks are good, you can choose the type of bricks according to the actual construction situation and functional requirements, both have their own characteristics, as for how to choose, or according to their actual needs, compare the best on it, only in this way can we achieve the purpose of saving money and building a safe house, but from the perspective of environmental protection, it is more appropriate to choose perforated bricks.

If your home is drier, you can choose to use perforated bricks, and if it is more humid, then choose small red bricks, because small red bricks are fired, and he has a good effect on dehumidification.

Compared with small red bricks, perforated bricks are inferior in quality and shape to small red bricks. Moreover, the small red bricks are harder to a certain extent. But the choice depends on your personal preference.

The advantage of porous red bricks compared to solid red bricks is that they are cheaper.

Only the frame structure of the whole pouring is made of porous red bricks, which are used as wall filling, and the porous red bricks themselves are not stressed.

Non-frame structure, the monolithic brick wall is stressed, and solid clay sintered red bricks must be used. Porous red bricks are not pressure-resistant.

Hollow bricks, red bricks, gray bricks, cement bricks, etc., each kind of brick has its own advantages and disadvantages. The red brick wall is cheaper than the gray brick, and the red brick is widely used when people build houses in life.

1. Perforated bricks are better than ordinary bricks in terms of heat and sound insulation. 2. The dead weight of perforated bricks is lighter than that of ordinary bricks. Disadvantages of perforated bricks: 1. The construction of hollow bricks is a little more troublesome than ordinary red bricks in operation. 2. Perforated bricks are more expensive than ordinary bricks.

Perforated bricks are used to reduce the weight of high-rise buildings in the college entrance examination, and if you build low-rise buildings around you, it is better to build solid red bricks, which are strong and durable.

Perforated bricks are more breathable than small red bricks, but perforated bricks are not as strong as small red bricks.

To build a house in rural areas, small red bricks are good, firm, good sound insulation, low cost and low cost.

The two kinds of bricks have their own merits, the red bricks are strong and durable, and the hollow bricks are breathable and environmentally friendly. I think the choice of brick varies from person to person. Most of my family chooses red bricks, and very few hollow bricks are used.

It is still better to perforate bricks, but now there are more people who choose Xiaohongzhao because it is cheaper.

I think the small red bricks are good, and many people use the small red bricks to see the house, with good hardness and good ventilation.

Of course, perforated bricks are good, because perforated bricks are not only beautiful, but also more conducive to the permeability of the house.

Nowadays, most of the houses are built with perforated bricks, and there are very few small red bricks.

In the north, small red bricks are good, and in the south, perforated bricks are good! After all, there is a temperature factor to consider.

Low-rise buildings are still small red bricks.

Of course, the repair of the house is a high-standard all-concrete structure, and the ten-level ** is not afraid

The red color is better, and the bricks without holes have better thermal insulation performance.

Overall, red bricks are good.

Let's take this case as an analysis. The scope of application of brick-concrete structure red brick is better. It is better to use a mixture for specific analysis.

The advantages of red bricks are compressive, the suspension screws are tight, and the embedded wire pipe has little impact on the wall;

The transportation and maintenance of clay-fired porous bricks is very large, and the quality of the master is high;

Kitchen and bathroom should consider hanging objects (cabinets, water heaters) walls, gravity walls, etc. red bricks;

Hole bricks can be accurately used for exterior walls and partition walls that are not load-bearing, because they are environmentally friendly, sound insulation and energy saving are very good.

The lower layer must consider and calculate the structure and load of the load-bearing wall, that is, the solid bricks must consider the 240 or 370 wall masonry, and whether the upper layer uses perforated bricks must be designed and calculated. Therefore, no matter what kind of brick it is, it must be calculated by design.

The masonry structure design code stipulates it! When the strength of perforated bricks is the same as that of red bricks, if the porosity of perforated bricks is greater than 30%, the strength will be reduced. That is to say, red bricks are better than porous bricks at the same strength.

But the masonry structure masonry 6 layers have reached the edge of the masonry height limit, if your home is in the seismic fortification 7 degrees (above, it is recommended that you change the frame structure!) Also do not use the upper part of the seismic wall of the sub-frame masonry, which is less solid than pure masonry. Don't change it!

It is recommended to set up the structural columns reasonably. Ensure the length of the wall between the windows, set up ring beams on each floor, 6 degree zone and 7 degree zone (area is also possible. It is not recommended to be too large.

The large opening of the masonry structure is very unfavorable for earthquake resistance, and the number of floors is high! Meters above the large bay as little as possible!

1. In terms of quality (structural stability and seismic performance of the house), solid red bricks are much more reliable than perforated bricks (that is, hollow bricks as you say).

In the area with a good foundation, the brick-concrete structure of the house can be built to more than 8 floors, but due to the national regulations to the house above 8 floors (including 8 floors) must be installed elevator, for this reason, the general brick-concrete structure of the house is below 8 floors, that is to say, the solid red brick can be built to more than 24 meters. Of course, the columns and beams are still made of reinforced concrete, but the main load-bearing is still brick walls.

2. Perforated bricks can be load-bearing, but their load-bearing capacity is weaker than that of solid, so at present, most of the external walls of houses with frame or frame shear structure are mostly made of hollow bricks as a separation and waterproofing effect.

3. In the township, most of the houses are made of solid red bricks, which should not be built with many floors, and there is also a layer of solid bricks, and perforated bricks are used on the top, which can reduce the cost and reduce the weight of the wall on the foundation.

4. If the number of layers is not much, then you can use long and empty, but a few bricks at the bottom or at least 2 meters below the ground, and above the ground beam, solid bricks must be used in order to prevent moisture. The moisture-proof and waterproof performance of hollow bricks is much worse than that of solid bricks.

Now the state no longer allows the use of pure clay bricks (i.e. "red bricks") to build buildings, and can only be used as auxiliary materials, such as the walls of the frame structure are filled with fly ash blocks, the top and bottom of the fly ash blocks are filled with clay bricks, and the top is obliquely built to prevent moisture.

Perforated bricks are mainly used in frame structures and brick muddy structure non-load-bearing walls, note that it is a non-load-bearing structure, this brick is a little bit of small weight, thermal insulation, sound insulation, can not be load-bearing, so it is generally only used for filling.

Therefore, the landlord said that this problem cannot be established, and neither of the two types of bricks can be used alone to build a building, but only filled.

Oh, this problem is not in the good with that, but in the quality of these 2 kinds of bricks, the bricks in the picture are called porous load-bearing bricks, the specifications are 240 * 115 * 90, if the quality meets the requirements of the country, with red bricks and perforated bricks, are the same.

In addition, when the brick-concrete structure is stressed, it is not simply a component that is stressed alone, it is a combination of forms of stress, as long as it meets the national quality standards, it can be used, and the quality depends on the configuration of other components and the structural layout.

The specification of solid red brick is 240*115*53, using solid and porous, in terms of cost, it is basically the same.

The hybrid structure, of course, is red brick, which is called hollow brick, not perforated brick.

Red bricks! Because red bricks have strong heat resistance and strong anti-penetration!

Perforated bricks are good, and solid bricks have been banned from national norms.

The perforated brick has the advantage of light weight, earthquake resistance, and energy saving.

In terms of construction quality, you can only use red solid bricks for 6 floors without frames, because its hardness and bearing capacity are more than ten times better than perforated bricks, and buildings without frames are not allowed to use hollow bricks in terms of quality. The reason why hollow bricks are widely used in current buildings is because the houses are now framed structures, and hollow bricks only play the role of sound insulation and heat insulation. If it is a frame building with more than 10 floors, it still cannot use hollow bricks for its exterior walls, but only for the interior walls.
