[China Aluminum Network] advantages of aluminum alloy template:
1. The construction period is short: the aluminum alloy building formwork system is a quick release formwork system, and the normal construction of a set of templates can reach three or four days, which greatly saves the management costs of the construction unit. Repeated use, low average cost of use: aluminum alloy construction aluminum formwork system uses the overall extrusion of aluminum alloy profiles made of the original alloy 6061-T6, a set of template specifications can be used over 300-500 times the construction, the average cost of use low.
3. Easy construction and high efficiency: Aluminum alloy construction formwork system is simple and convenient to assemble. The average weight is 30KG/m2. It is completely assembled by hand and does not require any assistance from mechanical equipment. (The worker usually only needs a wrench or small hammer for construction. It is convenient and quick. ) Skilled installation workers can install 20-30 square meters per person per day (compared with wood model: aluminum mold installation workers only need 70-80% of wood mold installation workers, and do not need skilled workers, only need to install before construction Staff can do simple training.)
4. Good stability and high bearing capacity: All parts of the aluminum alloy building formwork system are assembled from aluminum alloy plates. After the assembly of the system is completed, an overall frame is formed, the stability is very good; the bearing capacity can reach 60KN per square meter.
5. Wide range of applications: Aluminium alloy building formwork is suitable for use in places such as walls, horizontal floors, columns, beams, stairs, sill, and drift boards.
6. After demolishing the concrete surface effect: after the aluminum alloy construction template is demolded, the surface quality of the concrete is smooth and smooth, and the requirements of the facing and the fair-faced concrete can basically be achieved without negotiating, which can save the expense of levitation.
7. There is no construction waste on the site: All parts of the aluminum alloy construction formwork system can be reused. After the construction is demolished, there is no garbage on the site, and the construction environment is safe, clean and tidy.
8. Standards and versatility: Aluminum alloy construction formwork has many specifications, which can be assembled with different specifications according to the project; when replacing a used building template with a new building, only about 20-30% of non-standard plates need to be replaced, which can reduce costs.
9. High recovery value: After the aluminum alloy construction template is scrapped, when the waste disposal value is high, the average cost advantage is obvious (the recovery price per square meter is about 400 yuan).
10. Low-carbon emission reduction: All materials of the aluminum alloy building formwork system are in raw materials, in line with the national regulations on energy saving, environmental protection, low carbon, and emission reduction of construction projects. Many developed countries have already stipulated that construction projects are not allowed to use wood formwork and that they need to use raw materials.
11. The support system is convenient: In the traditional construction method, the template construction technology such as the floor slab and the platform is commonly used. On the other hand, the supporting poles of the aluminum formwork mold are relatively small (with an independent support spacing of 1200mm), which allows a large operating space, free passage of personnel, smooth material handling, and easy management on site.
Aluminum formwork construction is easy to control the size of the concrete structure, precision docking, easy mold release characteristics, to ensure that the surface of the concrete is smooth, smooth, avoiding the traditional wood mold construction produce a large number of construction waste (wood chips, concrete slag) of the drawbacks. The aluminum alloy formwork adopts the quick release system, which passes through the manual layer-by-layer transmission and changes the traditional construction method that depends on the tower crane and unloading platform, effectively speeds up the construction schedule, shortens the construction period, reduces the labor intensity, and improves the construction efficiency. The construction process is green, low-carbon and energy-saving, and it is in line with the development of a new type of green building concept.

At present, the commonly used templates for concrete pouring in the construction industry include steel templates, wooden templates, bamboo templates, plastic templates, and aluminum alloy templates. Steel formwork is heavy, easy to rust, and easy to bond with concrete in the process of concrete pouring, and it is difficult to demold. Wooden formwork is light in weight, but its strength is low, it is not waterproof, it is easy to mold and rot, and its reuse rate is low. The need to consume timber resources is not conducive to the protection of the ecological environment and forest resources; the disadvantages of the bamboo formwork are also low reusability, and can not be recycled; the plastic formwork is poor in rigidity, variability, and high in cost. The above-mentioned templates have poor durability and have a low level of production standards, and cannot ensure the quality of concrete works. Moreover, the construction speed is slow, the number of times of template turnover is low, and the material consumption is large.

Aluminium formwork system, made of high-strength aluminum alloy, has strong bearing capacity, light weight and flexible disassembly. It is convenient to realize one-time pouring, which makes the on-site operation simple and easy, and saves a large amount of on-site labor and time cost. Furthermore, the aluminum formwork system can be used repeatedly, and due to the renewal of the template materials, the construction industry has greatly reduced the waste and consumption of forest resources. And it is the integration of the construction formwork and support system from the construction equipment to the construction process, providing a complete solution for the concrete placement.
Aluminum template system has the following nine characteristics:
1. Lightweight: The products are all made of high-strength aluminum alloys, weighing an average of 25 kilograms per square meter. A large format template of about 2.5 square meters can easily be picked up by one person.
2. Flexible: Both the overall ground assembly and the construction method of lifting by tower crane can be adopted. In the construction site where the tower crane is insufficient, it can also be disassembled manually.
3. Simple: The main parts are pin, wedge and wall insert. Only a hammer and a little trained manual worker can quickly complete the installation and removal of the formwork system.
4. High-efficiency: The system design of integration, standardization, and modularization can easily realize one-time pouring, making on-site operation easy, and saving a great deal of on-site labor and work cost. Effectively shorten the construction period. Usually, the assembly and pouring of a floor can be completed every 3-4 days.
5. High-strength: The relatively new technology of aluminum alloy materials and reasonable template structure design, the aluminum template system bearing capacity of 60KN / m, and the design of the full steel plate bearing capacity.
6. Anti-rust: The aluminum alloy has good anti-rust performance, which brings great convenience to the subsequent use and maintenance of the aluminum formwork. Particularly suitable for applications in wet areas in the south.
7. Precision: The extrusion manufacturing process of aluminum alloy profiles can ensure the precise butt joints between the template frames, plus the characteristics of easy demoulding of aluminum formwork panels, so that the concrete surface is smooth and smooth, achieving the effect of finish and clean water.
8. Longevity: In the United States and other developed countries, if the use of properly maintained, all aluminum template recycling can be used up to 2500 times. Amortization costs are better than other types of templates.
9. Preservation: All the recyclable properties of aluminum alloys, as well as the continued high prices of precious metals in the international market, make the investment in the use of aluminum formwork systems increase the anti-inflation, value-preserving and value-added functions.
Before the design and construction of the project, do a detailed and accurate analysis of the project and the design of the construction plan, and cooperate with the product series of numerical modeling, systematization, and standardization of the aluminum formwork system, so that the problems that may be encountered in the construction are greatly limited to the plan. The design phase is solved. The quality precision aluminum formwork system uses high-strength aluminum alloy profiles welded to various standardized components in different modules. Product manufacturing process, aluminum joints and the overall accuracy of the template are much higher than the traditional template. In the overall test installation of traditional formwork and its construction methods, many installation problems are randomly handled by the construction site personnel, and construction efficiency and project quality are difficult to effectively guarantee. Before the aluminum formwork system was transported to the construction site, 100% of the entire project was installed for the project. All possible problems were solved in the factory, which greatly improved the construction speed and accuracy. Construction efficiency The aluminum formwork system is based on pin and wedge-based connections, making the installation process extremely simple. Ordinary manual workers need only a simple training to perform the job. The only tool used is a carpentry hammer. Especially in the construction site without tower cranes or tower cranes, due to the light weight of aluminum formwork, it can be hand-carried, greatly accelerating construction progress and improving construction efficiency. The construction period for assembling and pouring can easily reach 4 floors per floor. The top-touching and supporting system of the early-dismantling aluminum formwork system has achieved an integrated design, incorporating the early demolition technology into the roof support system, and greatly improving the turnover rate of the template. Excluding the large number of U-shaped brackets and wooden squares used in traditional construction methods, as well as steel pipe fasteners or bowl buckle scaffolds, reasonable design of products and construction methods will save material costs. The construction safety aluminum formwork system's wall molds, top molds and adjustable supports and even the design of related accessories have undergone complete calculations and experimental verifications to ensure that the entire system meets the 60kn/? design standards and that in accordance with relevant U.S. standards, there are 2 :1 The safety factor, to a large extent, removes the safety hazards caused by the uncertainties caused by equipment and construction. The environmentally-friendly recycling aluminum formwork system is made of high-strength aluminum alloy materials that can be recycled, and can be completely recycled. It basically removes the high dependence and waste of forest resources on building construction. The construction site does not require any construction work, keeping the environment clean and orderly, and does not produce waste materials and noise. Economical and reasonable In the United States and other developed countries, if the use of properly maintained, all aluminum template recycling up to 500 times. Each square meter of contact area, the cost of each pouring of the template, support, including all accessories is only 2.5-3 yuan. Coupled with the extremely high residual product of aluminum products, its economic efficiency is much higher than other types of templates.
