Foundation Formwork
For the implementation of modular structures such as tanks and silos and… the arc formats are used. These formats are similar to standard formats but without the horizontal straps. By considering rolling radius of the trailer we can be supply the various curvatures. Arc formats, such as modular ones are made in different sizes and dimensions and are attached by rolled tube to middle clamps.
The implementation of all the formatting and foundations, ranging from individual foundation, strip, mat, bascule, gradient foundation, ties and platform and short foundations and … by using modular format is very simple, economical and fast.
different foundation can be formatted and implementedby combining and connecting metal panels, tailor pipes, the connections such as pin and wedge fitting, pipe clamps to mold, punch corners and the use of internal and external corners and fillers.
By the way, it should be noted that foundation is the most voluminous and heavy part of the concrete structure and high volume of concrete and mold filling speed
Foundation formwork is an important component in construction operations, used for casting concrete and creating the final shape of the foundation. The choice of formwork depends on the type of structure, environmental conditions, and project requirements. Below, the Arta Bonyan Sanat team explains the types of foundation forms and their features for you:
Wooden Foundation Forms
These forms are made of wood and can be in the form of wooden planks or plywood boards. The features and advantages of these forms include:
Lightweight and easy to transport on-site. Lower cost compared to other forms like metal or steel. Higher reusability compared to other forms. Variety in dimensions and shapes that can be constructed.
However, wooden foundation forms also have drawbacks:
Less resistance to moisture and water, they may deform upon contact with water and moisture. Require frequent maintenance and repairs. Shorter lifespan.
Metal Foundation Forms
Metal forms for concrete come with numerous advantages:
High strength and resistance: Metal forms, due to the use of materials like steel, have high strength and resistance. This allows them to bear heavy loads and withstand pressure, vibrations, and external forces. High reusability: Metal forms can be used repeatedly in construction projects. They can be recycled and used in other projects, leading to cost savings and conservation of natural resources. High construction speed: Metal forms, due to their simple and lightweight design, can accelerate the construction process. Installing and replacing metal forms is easily achievable, significantly reducing construction time. Ease of connection: Metal forms can be easily connected and combined with other structural elements through simple and reliable connections. This feature increases the speed and accuracy of the formwork installation process. Suitable for high-volume projects: Due to their reusability and high resistance, metal forms are highly suitable for high-volume projects. They can handle heavy loads and are used in large and complex projects such as towers, bridges, and tunnels.
However, metal foundation forms also have drawbacks. They are heavier than wooden forms, which may pose transportation difficulties, and they have a higher cost compared to wooden forms.
Brick Foundation Forms
These forms are made of artificial bricks or sturdy and resilient bricks. Brick forms are usually used for small to medium-sized foundation forms. The features and advantages of brick forms include:
High resistance to pressure and load weight. Aesthetic appearance and the ability to create precise details in the structure. Reusability in similar projects.
However, brick forms also have drawbacks:
Higher weight and larger volume compared to other forms. Require more time and cost for construction and repairs. May require internal reinforcement in some cases.
Steel Foundation Forms
These forms are made of steel components and are used for constructing large and complex foundation forms. The features and advantages of steel forms include:
High resistance to pressure, impact, and carrying heavy loads. High flexibility in design and implementation. Greater reusability and longer lifespan.
However, steel forms also have drawbacks:
Higher cost compared to other forms. Require specialized equipment for construction and installation. Require skill and technical knowledge for proper use of steel forms.
Essential Characteristics of Foundation Forms
Key characteristics of a good form for foundation work include:
Minimizing expansion and contraction: The form should have features that minimize its expansion and contraction. This is important to ensure that the form undergoes minimal deformation after the concrete is cast, allowing it to be properly maintained. Sturdiness and rigidity: The form should have sufficient sturdiness and rigidity to remain stable during concrete pouring and support the weight of the concrete as much as possible. This feature prevents deformation and damage to the form. Adjustability: The form should be adjustable to accommodate the needs of the structure and the shape of the foundation, allowing it to be modified as required for a desired fit. Stability against structural loads: The form should have sufficient stability against structural loads. This characteristic is crucial as the form needs to withstand the pressure and weight of the concrete. Accuracy in dimensions: The form should have high precision in its dimensions to ensure that the final shape of the foundation is achieved correctly and is compatible with the desired dimensions and design.
Disadvantages of Steel Foundation Forms
The disadvantages of steel formwork compared to other types of forms include:
Higher cost: Steel formwork is more expensive due to the use of costly steel sheets, which may pose budget constraints for smaller projects. Heavyweight: Steel sheets are significantly heavier, requiring the use of mobile equipment such as cranes for handling and lifting form panels. This may pose challenges for some projects and may incur higher costs and time. Limitations in scale and form: Steel formwork typically has limitations in scale and form. This type of formwork may not be suitable for projects that require complex and diverse shapes, potentially necessitating custom formwork that comes with higher costs and time.
Need for skill and expertise: Using steel formwork requires a high level of skill and expertise. The design, construction, and installation of these forms require technical knowledge and suitable work experience. This can present challenges if sufficient expertise in this area is lacking.
