aluminium shuttering cycle times
The number of reuse cycles refers to the safe and stable number of times that aluminium shuttering can be repetitively used during the construction process. It is one of the crucial indicators for evaluating its quality and performance. In general, the higher the number of reuse cycles for aluminium shuttering material, the better its quality and durability.
The calculation of the number of reuse cycles can be determined through a comprehensive assessment of factors such as the quality of aluminium shuttering system, construction conditions, and maintenance management. In practical applications, construction parties typically evaluate and control the number of reuse cycles based on the usage status, maintenance records, manufacturer's provided design life, and usage recommendations of the aluminium shuttering system.
For construction parties, rational utilization of aluminium shuttering by maximizing its number of reuse cycles can effectively reduce construction costs, enhance construction efficiency, and contribute to minimizing resource consumption and environmental impact. Therefore, the concept and evaluation of the number of reuse cycles hold significant importance for construction parties in the selection and management of aluminium shuttering.
● Comparison of the number of uses for formworks of different materials
The number of reuses for formworks is closely related to their material and quality. Wooden formworks can be reused 4-7 times, steel formworks can be reused 20-35 times, and aluminium shuttering can be reused over 300 times.
1. How many times aluminium shuttering can be used?
aluminium shuttering is made of aluminium alloy and is an efficient and low-consumption green building material. Although aluminium shuttering price is higher, this formwork can be used for over 300 times, resulting in significantly lower average costs compared to wooden and steel formworks. Additionally, aluminium alloy formworks have environmental recycling and regeneration value.
The aluminium shuttering system adopts a modular design, allowing for quick installation and dismantling by workers, thereby improving construction efficiency and reducing the reliance on skilled labor. This significantly lowers construction costs on a large scale. Taking all factors into consideration, the aluminium formwork cost is much lower compared to regular wooden and steel formworks, making it a more economical and practical choice.
ns, the aluminium formwork cost is much lower than that of ordinary wooden formwork and steel shuttering, making it a more economical and practical choice.
2.How many times steel formwork can be reused?
steel formwork is a type of formwork material used in construction and is made of cold-rolled steel plates. Compared to other types of formwork, steel formwork has the advantages of high surface flatness and hardness, and low susceptibility to deformation. Therefore, it can be reused repeatedly, with a usage count of 30-50 times, without frequent replacement or repair. In addition, steel formwork also has features such as fire resistance, water resistance, and earthquake resistance, making it widely used in fields such as high-rise buildings, large factories, and bridges. However, due to its high density and heavy weight, moving and installing steel formwork requires the use of lifting and hoisting machinery. Additionally, installation and removal of steel formwork must be carried out by professional personnel.
3. How many times wooden formwork can be reused?
Wooden formwork is typically made from high-quality materials such as poplar and pine core boards. After being glued and pressed, the formwork is low cost, has a smooth surface, and is lightweight. Normally, the formwork can be reused for 4-7 turnovers. However, if the formwork is used beyond its recommended turnover limit, it may warp and become deformed, resulting in issues such as insufficient concrete filling or even formwork failure, thereby increasing costs associated with rework and personnel handling. Therefore, it is necessary to regularly inspect the condition of the formwork during the construction process and promptly replace any aged or deformed formworks to ensure construction quality.
● The factors influencing the number of uses for aluminium formwork shuttering
1.Material quality and durability: The quality of aluminium shuttering material directly impacts its durability and number of cycles for reuse. The 6061-T6 aluminium alloy material, known for its high strength and corrosion resistance, can withstand multiple construction uses without significant deformation or damage.
2. Maintenance and upkeep: It is important for the construction party to pay attention to proper maintenance and upkeep when using aluminium formwork shuttering. This includes regular cleaning, coating maintenance, as well as inspecting and repairing any potential damages. This measure can prolong the life and cycle times of aluminium formwork shuttering.
3. Construction techniques: Improper aluminium shuttering technology in construction can reduce the number of uses, such as unauthorized drilling or forceful demolding.
4. Usage environment and construction conditions: Construction environments that are humid or have high acidity/alkalinity can potentially damage the surface coatings of aluminium shuttering plates, reducing their durability and number of reuse cycles. Additionally, factors such as vibrations and pressure during construction can also cause damage to the plates.
5. Storage and transportation methods: Proper storage and transportation methods can prevent aluminium shuttering plates from being damaged by external forces or environmental factors, reduce impacts and friction, and prolong their lifespan.
