What are the characteristics of ALC wall panels, and the construction technology of ALC wall panels

I believe that many people now have poor sound insulation when they are resting at night, and let the outside noise affect their sleep. Now the ALC wall panels on the market can protect the walls well and effectively play a role in sound insulation. However, due to the large variety of brands, many consumers are very confused when choosing. What are the characteristics of ALC wall panels? Next, let the editor take you to understand.

1. Introduction of ALC wall panel

1. ALC board is made of fly ash (or silica sand), cement, lime, etc. as the main raw materials, and is a porous concrete forming board (including treated steel reinforcement) that is cured by high pressure steam. ALC board can be used as both wall material and roof panel. It is a new type of building material with superior performance.

Second, the characteristics of ALC wall panels

1. Sound insulation: The material is a porous material composed of a large number of uniform and disconnected tiny pores, which has good sound insulation performance. Sound insulation 45.8dB;

2. Fire resistance: ALC sheet is a non-combustible inorganic material with good fire resistance. As a wallboard, the fire resistance limit of 100 thick plate is 3.23 hours; 150 thick plate> 4 hours; 50 thick plate protects steel beam fire resistance limit> 3 hours; 50 thick plate protection steel column fire resistance > 4 hours; all exceed the first-class fire resistance standard;

3. Durability: ALC is an inorganic silicate material, which is not aging and has good durability. Its service life can match the service life of various buildings;

4. Freezing resistance: good freezing resistance, mass loss after freeze-thaw test <1.5% (national standard <5%), strength loss <5% (national standard <20%);

5. Impermeability: good impermeability, 5 times better than standard bricks;

6. Softening coefficient: high softening coefficient, Rw/Ro=0.88;

7. Environmental performance: The material is non-radioactive, no harmful gas escapes, and is a green and environmentally friendly material;

8. Constructability: ALC plate production is industrialized, standardized, and installation is industrialized. It can be sawed, cut, planed, drilled, and constructed dry, with high speed;

9. Compatibility: ALC board has a complete application supporting system, equipped with special connectors, grouts, repair powders, interface agents, etc.;

10. Simple construction and low cost: using this material does not require plastering, reducing the cost by 20-25 yuan/square meter; you can directly scrape putty and spray paint;

11. Good surface quality and no cracking: using this material because of the dry construction method, there is no hollow crack on the board surface;

12. It is convenient to hang air conditioners, water heaters, wash basins, etc., and the construction is simple and easy to handle;

3. The benefits of ALC wall panels

1. The ALC board has a scientific and reasonable node design and installation method. It ensures the stability and safety of the wall outside the plane on the basis of ensuring the strength of the node. The body has the followability to adapt to the large horizontal displacement in the plane.

2. This can ensure that the building maintenance structure will not be damaged greatly under the action of strong wind or seismic force, and has strong seismic performance. In the 1:1 simulated earthquake test, after the earthquake test with an intensity of 10.5 degrees (1.2g), none of the plates of the tested building model were broken, and none of the 120 NALC plate installation nodes were damaged.

3.ALC panels have been used as interior and exterior wall panels, roof panels, etc. in more than 1,000 domestic and foreign construction projects.

Through the above content, everyone must have a new understanding. I hope it can help you when using it. The editor would like to thank every reader for reading. It is your reading that gives us the greatest support and motivation.

Advantages of ALC Wall Panels

Liaocheng Yasheng New Building Materials Co., Ltd., which specializes in ALC wall panels, ALC wall panels, and ALC panels, will introduce you to the advantages of lightweight partition panels.

In addition to the high-quality functions of sound insulation, environmental protection, moisture and water resistance, and fire protection that we all know, the lightweight wallboard is still lightweight and economical. We know it just by looking at the signature of the lightweight partition board. It is very lightweight. In fact, the weight of the 75mm thickness of the lightweight wallboard is only 1/7 of the weight of the 120mm thick masonry, so it is not necessary to carry such heavy materials upstairs during construction, to a certain extent. The convenience of adding immediate construction also reduces the labor intensity on a certain basis, and it also has certain advantages in terms of the layout of the house.

In addition to being able to arbitrarily separate the layout of the room, ALC wall panels usually use 75mm wall materials when decorating, so the thickness of ALC wall panels is 85mm less than that of 120 brick walls, which means energy saving and light weight. For every extension of 11.8m, the application area can be increased by 1m. In this way, it also increases the area of ​​your house, which is a good job for you.

ALC wall panels add the functions of sound insulation, environmental protection, moisture resistance and waterproof, thermal insulation and other functions mentioned before. In the cold winter, you do not need electric blankets, and you do not need to bake hand warmers. In the hot summer, you do not need to blow electricity. The fan does not need to turn on the air conditioner, and it also saves a lot of electricity for your home. Its environmental protection function also determines its long-term development trend, so in the future, lightweight partition boards will also be used. It is a wall material that can be installed in every household in our life, so if you choose a lightweight partition board, you will also reduce the trouble of re-decorating in the future, and even if you want to re-shape the house, use lightweight partitions. The wallboard is also an excellent improvement for future renovations. The lightweight wallboard does not need cement, you don't have to worry about getting your home dirty, you can cut and gather it at will, and it is also an excellent improvement for your decoration project. Wouldn't such a lightweight wall panel make you feel comfortable and comfortable to live in?

ALC wall panel construction technology

The common specifications of the inner wall panels of ALC sheets are generally divided into: 75mm, 100mm, 125mm, 150mm, 175mm, 200m according to the standard thickness:

, the width is uniformly 600mm, and the narrow board less than 600mm can be cut on site (this board is generally located on the side of the wall column, and should not be placed on the side of the door and window holes). The length is based on the actual height of the wall on the construction site. Review the net height of the wall before installation. The actual length of the ALC sheet is generally 2-4 cm shorter than the net height of the wall at the installation location; according to the slot, it is divided into slotted slab and flat slotted slab. plate. Requirements for incoming boards: The site for on-site stacking should be solid, flat and dry. When stacking, they should be stacked according to specifications and grades, the bottom should not be directly on the ground, and the bottom should be covered to prevent rain. The board should be placed on the side, the stacking height should not exceed three layers, and the bottom board should be about 600mm away from the board end.

Place 100mm*100mm dunnage at the place. When unloading, use nylon sling and pay attention to the maximum load of the sling. Any plate with penetration, cracks, bumps, or serious damage is strictly prohibited in the project. Inner wall panel installation is generally vertical installation (can also be installed horizontally)

, Its connection accessories generally include U-shaped cards, pipe cards, right-angle steel parts, angle steel, L-shaped accessories, bar-shaped connectors, hook bolts, S steel plates, potting steel bars and so on. One of the most commonly used and relatively economical connection methods is the U-shaped card. According to the project floor plan and the on-site positioning axis, determine the installation position line of the ALC board, which is generally the edge line above and below the pop-up wall board. Mark the building elevation of the floor, which is required when installing the wall panels at the door and window openings. Install the U-shaped card according to the position line of the bounced wall. One U-shaped card for each board is welded to the steel beam, or connected to the concrete with two shooting nails. The middle position of the U-shaped card should face the seam between the board and the board as much as possible (except the first one), and the height of the stuck board should be ≥20mm. If the method of fixing the U-shaped clip is to be fixed by shooting nails, there must be no less than 2; if it is fixed by spot welding, there must be no less than four fixed points. , undercut, burn through and needle-shaped pores and other defects, there is no residue at the welding and anti-rust treatment.
