The curtain wall aluminum veneer has a unique texture, rich color, durability, and various appearances, which can be perfectly combined with glass curtain wall materials and stone curtain wall materials. With perfect appearance and high quality, it is well received by the owners. Its weight is only one-fifth of marble and one-third of the glass curtain wall, which greatly reduces the load on the building structure and foundation. At the same time, maintenance costs are low and cost-effective. Below, I will share with you the "application scope and development history of curtain wall aluminum veneer", I hope it will be helpful to you.

First of all, the treatment process of curtain wall aluminum veneer can be divided into two methods, one is anodizing method, and the other is electrostatic spraying method. The anodized oxide film is generally more than 12 acres, the color is only two kinds of bronze and white, the color is monotonous, and the more serious disadvantage is that the color depth of each aluminum plate is different, and the overall effect of many wall panels forming a curtain wall is ugly.

This shortcoming cannot be eliminated. It can be said that it is not caused by the production process, but because the aluminum plate is not composed of a set of numbers, chemical composition, a little difference, plus the oxidation solution electrolyzer and other factors, the current density is different, and how much S is after oxidation If there is a difference, the color of the boards may not be obvious, if they are arranged together, it will be obvious. Therefore, the surface treatment of aluminum curtain walls can never be anodized.

The curtain wall aluminum veneer is generally 2--4mm aluminum alloy plate. When the wall panel is made, the metal plate is processed according to the requirements of the second design, and the metal plate is directly folded. The four corners are welded in a closed groove by high pressure. The back of the wall panel is connected to it. In order to strengthen the fixing bolts, electric welding nails are reserved. After the metal plate is processed, two to three layers of fluorocarbon paint are usually sprayed, and the thickness of the paint film is 30-40 microns. Aluminum alloy veneer is easy to process into arcs and multi-folded edges or acute angles, which can adapt to the changing needs of exterior wall decoration, and is rich in colors. It can be designed at will and the owner can choose colors. The architect in the true sense broadens the SPA design. Wow.

Another method of surface treatment of curtain wall aluminum veneer is electrostatic spraying. Spray is divided into powder spray and liquid spray. The powder coating materials mainly include: polyurethane, expanded resin, epoxy resin and other raw materials with high color retention pigments, and dozens of different colors of powder coating can be obtained.

Powder spraying, anti-collision, anti-friction, impact 50 kg, aluminum plate deformation, spray coating cracking, dripping layer intact, resistance to dilute acid and mortar. The disadvantage is that the long-term exposure of ultraviolet rays is worried about the chromatic aberration of the yin and yang surface after several years. The powder spray foam produced by many domestic manufacturers has a large weight difference. Some powder foams contain gold powder and are suspended after the powder foam. With the change of sunlight, there will be changes between day and dusk, and the depth of nail color is different. Choose powder foam. Agent. m Spray paint draws attention.

At present, the construction industry has become a consumption hotspot and an important economic growth point in China, and domestic demand will grow steadily. Driven by the renovation of old cities and the construction of new cities across the country, the overall aluminum curtain wall market will continue to grow.

The curtain wall aluminum veneer has very light materials and very excellent practical properties, such as fire resistance, moisture resistance, and sound insulation effects, and its own potential is very large. At present, my country's environmental protection problems are prominent, and the contradiction between energy supply and demand is also increasingly prominent. The state attaches great importance to the sustainable use of energy and environmental protection, and has introduced a series of energy conservation and environmental protection measures.

The main products of aluminum curtain wall are exposed frame, dark frame and aluminum curtain wall. With the increasingly severe energy crisis situation, my country is gradually strengthening the promotion of building energy conservation, aluminum curtain wall product structure is afraid of major changes, energy conservation and environmental protection will be the main development trend of aluminum. A curtain wall. 1. Curtain wall tools:

Toothless saw blade cutting machine, hand drill, impact drill, nail gun, various specifications of drill bits, wrenches, screwdrivers, hammers, ink threads, vertical threads, nylon threads, steel belts, welders, oxygen cutting equipment, suction cups, electric hangers Blue, plastic injection gun, pneumatic R life-saving gun, seat belt, etc.

2. Material preparation before entering the venue:

This part of the work is the preliminary work of the project, which should be completed on time, and the quality and quantity should be guaranteed according to the principle of construction services. details as follows:

(1) After the contract is signed, the designer should put forward the material plan for this project in a relatively short period of time based on the construction drawings of this project and the curtain wall project plan.

(2) The project manager department and the production department cooperate with each other, formulate the processing plan of this project according to the construction schedule and the actual situation of the project site, rationally organize and arrange the production to ensure timely arrival. product.

three. Installation process:

Pay-off→Fixed frame connector→Fixed frame→Aluminum plate installation→Joint construction treatment→Inspection

4. Precautions for installation of curtain wall aluminum veneer:

1. The variety, quality, color, pattern and line of the aluminum plate should meet the design requirements and have a product certificate.

2. When the curtain wall frame adopts profiled steel keel, its specification and shape should meet the design requirements, and be treated with rust removal and antirust.

3. Aluminum rivet core should be used when the design is not required for the installation of aluminum plate, and a rubber ring must be inserted in the middle. The spacing of hollow rivets should be controlled between 100-150 mm.

(1) Pay off

Fix the skeleton and bounce the skeleton to the bottom. The skeleton is fixed on the main structure, and the quality of the main structure is checked before laying out.

(2) Fixed skeleton node

The fixed skeleton is welded to the column of the main structure.

(3) Fixed skeleton

The skeleton is pre-preserved. The position of the mounting frame is accurate and the combination is firm. Check the centerline and surface elevation after installation. In order to ensure the installation accuracy of the board, it is recommended to use theodolite to penetrate the vertical frame of the beam. Appropriate treatment of deformation joints, settlement joints, and variable cross-sections to meet the requirements of use.

(4) Install aluminum plate

The installation and fixing of the aluminum plate should be firm and reliable, and the operation is simple and convenient.

(1) The gap between the board and the board should be treated internally to make it flat and smooth.

(2) After the aluminum plate is installed, cover the easily contaminated parts with plastic film or other materials.

5. Aluminum shed construction plan:

1. Tools for aluminum canopy:

Toothless saw blade cutting machine, hand drill, impact drill, nail gun, various specifications of drill bits, wrenches, screwdrivers, hammers, ink lines, vertical lines, nylon lines, steel belts, welders, oxygen cutting equipment, plastic injection guns, Pneumatic riveting gun, seat belt, etc.

2. When installing the aluminum plate, cover it with plastic film or other easily contaminated materials. The function of the composite aluminum curtain wall mainly belongs to the exterior decoration and outer protection of the building, that is, the building itself has ordinary brick walls or other types of walls. The composite aluminum curtain wall installed outdoors not only has its own decorative effect on the building, but also plays a role of external protection for the building. Such aluminum curtain wall itself needs better wind resistance, water resistance, air tightness and weatherproof sealing system.

Before the production and installation of the composite curtain wall aluminum veneer, the architectural design and construction drawings should be checked, and the building should be re-inspected, and the original design should be adjusted according to the actual measurement results before processing and assembly. The equipment and tools used for the processing of curtain wall components shall meet the requirements of the processing accuracy of curtain wall components, and the measuring tools shall be checked regularly.
