metal curtain wall plateIs designed for industrial plants and all kinds of building exterior wall insulation decoration and indoor insulation ceiling design and development of light fire insulation board. The outer panel of this product adopts color steel plate/aluminum plate with various finishes, the core material is fire-resistant insulation rock wool, and the inner panel can be made of color steel plate or aluminum foil according to the requirements of use. It is produced by automatic continuous production line, with stable product quality and wide application.

Flexible application of steel plate and aluminum plate, single-sided steel plate or aluminum plate, flexible production of small batch orders, high flatness of the board surface, no bulge, diverse texture and texture of the board surface, and low engineering loss. The steel structure industry should seize development opportunities, promote the application of steel structures in the construction field, increase the proportion of steel structures in public buildings and government investment and construction, and promote earthquake-resistant buildings such as light steel structure integrated houses in areas with high incidence of natural disasters such as earthquakes. In the face of major development opportunities such as the construction of the Central Plains Economic Zone and green building actions, the meeting proposed that the steel structure industry should launch more energy-saving, environmental protection, and green recycling products to meet market demand.

Why do you want to use metal curtain wall panels now, instead of stone curtain walls, the advantages of metal curtain wall panels are very prominent.

Metal curtain wall plate construction matters needing attention:

During the construction process, if the quality assurance data is not properly stored, it may cause data loss; some small construction units do not have quality assurance data, and improper handling will cause the engineering facts to be inconsistent with the quality assurance data. In the construction process, due to the incomplete quality assurance data, sometimes the complete completion data is illegally provided in the unit of real estate, which affects the construction period.

Problems in the installation of metal curtain wall panels:

According to the index, the metal curtain wall plate should have a waterproof sealing layer of 3.5mm ~ 4.5mm, and keep the surface of the sealing layer smooth. If the sealing layer is too thick, the pulling force is weakened, and if it is too thin, it is easy to leak water and reduce the sealing effect. Not only the thickness of the sealing ring, the uneven laying of the sealing ring will also affect the quality of the project. The commonly used connection mode of metal curtain wall plate connection is embedded parts or expansion bolt connection. If the position of the embedded parts is not embedded according to the design requirements, the phenomenon of secondary embedding may occur during the construction process, resulting in unstable connection, such as excessive spacing between bolts and columns.

Material problems in the construction of metal curtain wall panels:

In the process of purchasing materials, unnecessary quality certificates are often generated for the purchased materials, which brings additional difficulties to the inspectors in judging and screening the purchased materials. Metal curtain wall panels contain a lot of materials, such as hardware, bolts and other quality assurance, will bring great hidden dangers to the project. In addition, if the rubber for engineering structures is not checked for its adhesive strength at the time of purchase, the impact on the project will be irreversible. There are many types of glue, and their use is also different. They need to be tested first and then resized; some need to be bonded first and then tested. In the absence of a report of adhesions, its method of use cannot be determined.

Stone Curtain Wall:

1, natural material, bright and transparent, hard, long life.

2, frost resistance: stone in the wet state can resist freezing and thawing, no obvious damage. This property is called frost resistance. When the temperature is as low as -20 degrees Celsius, the water in the pores of the rock will freeze, and the water in the pores will expand to 1/10 of the original volume. If the rock cannot resist the force of this expansion, it will be destroyed. Generally, if the water absorption rate is less than 0.5%, its antifreeze performance is not considered.

3. Compressive strength: The compressive strength of stone will vary due to factors such as mineral composition, crystal thickness, uniformity of cementitious substances, load area, load action and settlement angle. Other things being equal, generally dense materials with fine crystalline particles and bonded to each other have higher strength. Dense volcanic rocks have no difference in compressive strength after drying and water absorption saturation (very low water absorption). If it is porous, water-afraid cemented rock, its wet and dry strength has obvious difference.

Many serious hazards of heavy stone for high-rise building exterior walls have not been fully regulated in the construction industry. Many stone curtain wall projects are winning the bid at low cost and have individual subcontracts to win the bid at low prices and cut corners to avoid losses. High-rise (50-100 meters high) stone curtain wall per square meter of 100-200 yuan of low-grade granite is indeed a lot. This is very dangerous.

2, many design institutes are not familiar with the curtain wall, you can mark the scope on the drawings, indicating what kind of curtain wall. The stone curtain wall is no exception. Designed by the winning curtain wall company. Some design institutes require structural engineers to carefully review, but most design institutes are subject to formal review. Uncontrollable design is dangerous.

3. The state requires a supervision company to be responsible for the quality of every construction project. This is completely correct and necessary, and is the key to ensure the quality of the project. Unfortunately, many supervision engineers are civil engineers and do not understand curtain walls, let alone stone curtain walls. This is due to the lack of curtain wall materials in the supervisory training materials. Much of the supervision is done by retired technicians. Without training, curtain wall supervision is not understand. How do we control the quality of completion? The construction quality inspection stations in various places often encounter various difficulties in quality inspection due to little learning of new technologies.

The fire resistance of the stone curtain wall is very poor, especially in high-rise buildings, where fires are generally ignited indoors. A fire in a building will raise the temperature of the stainless steel plates and metal structures that hang the slate, causing the steel to soften and lose its strength. The slate "rain" will fall from the upper floor, posing a danger not only to pedestrians, but also to firefighting difficulties. It's like the collapse of the World Trade Center in the United States. Because the World Trade Center is all steel, steel softens and loses strength at high temperatures, and the World Trade Center collapses from top to bottom.
