GRC lightweight partition board, also known as glass fiber reinforced cement, has stable performance, wide application and low price, so it is well known by the majority of people. The grc lightweight partition board market is a mixed bag. When we actually purchase it, we need to comprehensively consider the specific situation and make a reasonable choice. Then the editor will introduce to you in detail some relevant information about grc lightweight partition boards. They are the price of grc lightweight partition boards and the methods or prevention measures to solve the cracks of lightweight partition boards. The GRC lightweight partition board installation and construction plan introduces the text and picture content of these three sections.
1. Price of GRC lightweight partition boards
The price of GRC lightweight partition boards currently on the market generally ranges from 45-100 yuan/square meter. Different products vary. The materials are different, the construction difficulty is different, and the prices are also different.

2. Solving the cracks in lightweight partition boards Methods or preventive measures
1. The contact area between the wall panel and the ground must be dense to prevent the wall panel from sinking.
2. For existing cement-glued sealing materials, firstly, due to the addition of glue, the dried sealing materials will shrink significantly and crack. If the glue is too small, the cement will not gel properly and will easily pulverize. Nowadays, most seam sealing materials are prepared on-site by the installation team. Most of them cannot add glue according to regulations, and the amount of glue added is also unstable, large or small, which seriously affects the installation quality.
The solution is to replace the standard wall panel installation special sealant. Installation is more convenient and standard.
3. Introduction to the installation and construction plan of GRC lightweight partition boards
GRC is the English abbreviation of Glass Fiber Reinforced Cement. It means "using alkali-resistant glass fiber as the reinforcing material, low-alkalinity high-strength cement mortar as the cementing material, lightweight inorganic composite material as the aggregate, and implementing the national JC666 standard;" GRC has thin components, high stretch resistance, Good impact resistance, low alkalinity, small free expansion rate, reliable anti-cracking performance, stable quality, moisture-proof, thermal insulation, non-combustible, sound insulation, can be sawed, drilled, nailed, chiseled, the wall surface is flat, easy to construct, and avoids Wet work, improve the construction environment, save land resources, light weight to reduce the load in the building (1/6-1/8 of the weight of clay bricks) reduce the foundation and beams, reinforced concrete, reduce the total project cost, expand the use area . It is the best material to replace clay bricks in non-load-bearing parts of buildings. It has been widely used in recent years and is a new lightweight wall material recommended by the National Building Materials Administration and the Ministry of Construction.
Because GRC lightweight partition boards are installed in non-load-bearing parts of the building, the required installation locations are the places with the largest settlement deformation and the weakest load-resistance capacity in large spans. Due to the tongue and groove of the lightweight partition boards Groove is a special feature of assembly connection and smooth surface. It is easy to cause cracks at the connection between boards and between boards and doors and windows. When concentrated load is applied, it will cause vibration and deformation of lightweight wall panels, resulting in cracks and hollowing, which is detrimental to GRC strips. The board assembly method, pipeline pre-embedding, drilling, splitting grooves, equipment installation, surface plastering quality issues, etc. have raised new topics and proposed some preventive measures.
The main reasons that easily cause cracks in lightweight partition boards: Any object changes in the atmosphere. The cement mortar is affected by thermal expansion and contraction or positive and negative wind pressure changes. It is affected by load-bearing external pressure. The difference in lateral pressure at different parts of the space is very large, and the overall dimensions of the structure also change, resulting in different stress directions and sizes of the lightweight partition boards. In addition, each lightweight partition board shrinks and expands independently. This change occurs again and again as the temperature rises and falls.
Most of the old-fashioned lightweight partition boards with concave and convex grooves produced in the past have cracked to varying degrees after three months to one year of construction. The joints of the boards and the connections between doors and windows are particularly obvious. Even if the surface is treated with anti-cracks, cracks will appear. Cracks are only a matter of time. This is also a common problem in lightweight partition boards across the country. For the above reasons, our scientific research institute has successfully developed a double dovetail interlocking structure GRC lightweight partition board, which is connected by seam interlocking The new technology has effectively solved the problem of longitudinal cracks in many high-rise projects and has obtained national patents.
Above we have introduced three aspects of information about grc lightweight partition boards in detail. They are the price of grc lightweight partition boards and the methods to solve the cracks of lightweight partition boards or Preventive measures and GRC lightweight partition board installation and construction plans introduce the text and picture content of these three sections. Through the above introduction, we understand that grc lightweight partition board refers to glass fiber reinforced cement. With its stable performance and cost-effective market price, it has a wide range of applications in many fields in our daily production and life. application.
