What is the minimum required thickness for pile cap?
Pile cap should no less than 1.5 times the dia of pile
Terms easing and striking as they relate to formwork?
In formwork, "terms easing" refers to the gradual release or adjustment of tension in the formwork system to prevent sudden movements that could damage the structure or the formwork itself. "Striking," on the other hand, is the process of removing the formwork after the concrete has set and achieved sufficient strength. Both processes are critical to ensuring the integrity of the concrete structure and the efficient reuse of formwork materials. Properly timing these actions minimizes the risk of defects in the finished product.
Why stiffener is providing below the pile cap?
Stiffeners are provided below the pile cap to enhance the structural integrity and load distribution of the foundation system. They help to resist lateral forces and prevent buckling, ensuring stability under various loading conditions. Additionally, stiffeners can reduce stress concentrations and improve the overall performance of the pile cap by distributing loads more evenly to the underlying piles. This reinforcement is particularly crucial in areas with high seismic or wind loads.
The differences between kicker and kickerless formwork?
the only difference is for the next pour of concrete your formwork should be on a perfectly set layout. You dont have a STARTER to place your formwork against, so more precision is required for the next lift of concrete.
What is superstructure and substructure for bridges?
Items of Work which are below the Bearing viz pile cap, pier, pier cap are consdered as sub structure whereas the items above the Bearing viz girder and deck slab are super structure. Ansered by Rajiv Shah
How do you measure pile cap formwork?
It is very simple. Just calculate the perimeter of the pile cap using the pile cap plan and just multiply this perimeter by the depth of the pile cap which can be worked from the sectional drawings or sometimes it is specified in the plan drawings itself. Eventually you get the formworks in sqm.
What is the minimum required thickness for pile cap?
Pile cap should no less than 1.5 times the dia of pile
What is the allowable eccentricity of pile?
Pile eccentricity will allowable up to maximum 75mm. Above that we can proceed pile cap works by increasing the size of pile cap.
Method of statement of pile cap?
A pile cap is a part of a cement or concrete formation. The method statement shows how the pile caps should be made.
What is allowable eccentricity for pile?
Concrete piles cannot be driven at precise intended location; This is true for bored piles also. For practical reasons various country design codes restrict the permissible deviation. In Indian code this value is specified as 75 mm. This plays important role in pile-cap design. The deviation smaller than this will never be reported. So pile cap sizing needs to be based on the worst possible direction deviation. The pile eccentricity is one of the important aspects in pile cap shear strength calculation as well as pile cap reinforcement calculation.
What is the sawN formwork?
Sawn formwork is formwork that for concrete structure that needs to have plaster and paint finish.
How do you stop the smell of a creosote piling?
Sleeve over the pile with a slightly larger composite piling(Pearson pile) , top with PVC cap.
What is the differences between wrought and sawn formwork?
Wrought formwork is created by bending and shaping metal sheets or rods into the desired formwork shape, often using heat and mechanical force. Sawn formwork, on the other hand, is fabricated by cutting and shaping wooden boards or panels to the required dimensions for formwork construction. Wrought formwork is typically more durable and reusable than sawn formwork, but it is also generally more expensive and requires specialized equipment for fabrication. Saw formwork is more commonly used for temporary formwork applications due to its lower cost and ease of construction.
What is cut off level in pile foundation?
Piles are used in foundations to give a better base for structures. The appropriate pile cut-off level is commonly around 75mm above the underneath of the pile cap.
What is cut-off level in pile foundation?
Piles are used in foundations to give a better base for structures. The appropriate pile cut-off level is commonly around 75mm above the underneath of the pile cap.
Define ''striking''as regards to formwork?
It is dismantling formwork once concrete is sufficiently hard.
What is a wrot formwork?
Wrot Formwork is fair finish surfaces made up of steel or iron. Formwork is when wooden boards and bolts are used to shape concrete while it is setting.
