Fast Form Bracket System offers complete slab wall & sheet pile capping formwork Solution

Fast-Form provides complete solution for different types of pile cap, slab, base, beam, wall and sheet pile capping beam formwork whether they come in straight or radius, single or double sided.

This system can efficiently bolts together to facilitate casting kickers, plinths, hang bolts as well as monolithic bund walls etc.

There are 2 types of bases to pin directly to hard-core and ground by means of road pins, or bolt with re-usable concrete bolts to slabs and blinding concrete or even fasten them to decking with wood screws.

This system can be used without any difficulty. Just attach the brackets in a line and plumb up, screw on your ply from behind and pour your concrete.

Brackets are angled forward or back to make adjustment with sloping and battered pours along with irregular ground, thus making them much more compliant as compared to timber or panel systems.

The brackets are generated from superior grade galvanized steel to get rid of rust and they have longevity of 25 years plus. They are strong and do not get damaged. They can be also used underwater. Different sizes are available which range from 150 / 200 / 400 / 600 / 800 / 1200 & 1800mm high.

KEY BENEFITS:

• SAFETY: Access, handrails & toe boards, lightweight system that can be easily set up manually instantly and securely.
• SPEED: No need of de-nailing, lightweight and user-friendly system much faster as compared to conventional process and very simple to use with low labour skill levels.

• COST: It is very cost-effective as compared to timber with reduced labour and plant costs.
• ENVIROMENTAL: Little or no timber wastage and 100% completely recyclable materials which significantly minimize carbon emission deliveries.
• BETTER FINISH: Fair face finishes are obtained easily. The brackets are available with an F4 finish. So, fewer remedial works are required. Ply is fixed from behind systems, so, there is no marks on face of the concrete and any grade ply can be utilized as per your requirement.

Some practical issue prior to start foundation design

In foundation design, there may occur different types of issues associated with construction and costs.

Given below, the details of main issues :-

1. The foundations should be retained as shallow as possible, suitable for coping up with climatic effect, and strength of the surface soil; particularly in waterlogged ground. Excavation in severely waterlogged ground is extravagant and time consuming.

2. Expensive and complicated shuttering details should be bypassed specifically in stiffened rafts. Proper care should be taken with buildability.

3. Curtailment in the costs of piling, betterment in ground treatment, improvements in soil mechanics, etc. have significantly impacted the economics of design, and various standard solutions becomes obsolete. So, it is very much important to evaluate construction costs and methods on a regular basis.

4. Designers should have clear ideas on the assumptions which are provided in design. These range from the inconsistencies of ground conditions, the infrequent unsuitability of refined soil analyses and the feasibility of construction.

5. The authenticity of the soil analysis, through vital evaluation.

6. Impact of construction on ground properties that range from vibration from piling, degradation of ground uncovered with excavation in unfavorable weather conditions, exclusion of overburden, seasonal disparity in the water-table, compaction of the ground by construction plant.

7. Impact of changeable shape, length and inflexibility of the foundation, and the requirement for movement and settlement joints.

8. Consequences on finished foundations of sulfate attack on concrete, ground movements because of frost heave, shrinkable clays, and the impacts of trees; also modifications in local environment due to new construction, re-orientations of heavy traffic, setting up of plant in adjacent factories inducing impact and vibration.

9. Rapid but invaluable construction is more cost-effective as compared to low-cost but slow construction to clients to bring quick return on capital investment.

10. Impact of new foundation loading on obtainable adjacent structures.

Benefits of concrete covers blocks in RCC work

This construction video tutorial will guide you to make concrete cover block or rebar spacer at a reasonable cost.

A rebar spacer belongs to a object that fastens the reinforcing steel or "rebar" in reinforced concrete structures since the rebar is amassed in place before the pouring of final concrete. The spacers are remained in place for the pour to set the reinforcing in place, and turn into a permanent part of the structure.

When RCC work is going on, implanting steel in concrete (called as cover) is a vital process for resisting rebar from decaying as well as arranging fire protection to the rebar. If the proposed cover is not arranged, the rebar will start to decay in due course of time and will lead to collapsing of the structure beforehand. So, cover blocks can extend the life of the structure considerably without incurring so much expenses.

The exact amount of cover is set by the application and the environment (e.g., is the RCC under water, etc.)

In India, following are considered as the standard size for the covers :

Slab : 20 mm
Beam : 25 mm
Column : 40 mm
Foundation : 50 mm

Concrete covers ensure the accurate position of steel, thus allowing in the practical application of the theoretical specifications of concrete construction. The cover of the steel concerning a specific construction component (for instance in a concrete slab or a beam) should be usually constant inside the element.

The application of covers can be beneficial to the areas where high earthquake activity along with corrosive environment (like proximity to salt water of sea) occurs.

How to design the reinforced concrete wall

You have to design the Reinforced concrete wall similar to a compression member. Reinforced concrete wall is suitable when there are no beams and load transmitted from the slab is massive or the density of the masonry wall is restrained.

RCC Wall is segregated as follow:
• Plain concrete wall, when rein. < 0.4%
• Reinforced concrete wall, when rein. > 0.4%

Load from slab is transmitted as axial load to wall. When depth is greater, it is known as RC wall. Design is identical to a RC column, breadth is similar to the density of wall and depth is equivalent to 1m. The design of RCC Wall is based on the following factors.
• Axially loaded wall
• Axially loaded with uniaxial bending

Categorization of concrete walls:

1. Plain concrete wall
2. Reinforced concrete wall

Under plain concrete wall, the reinforcement included is under 0.4% of c/s. In reinforced concrete wall, the proportion of employed steel is in excess of 0.4% and is designed in the same way as reinforced concrete columns. Slenderness ratio is equivalent to minimum of (l/t or h/t), where, l denotes effective length of wall, h stands for effective height of wall, t stands for thickness of wall. When < 12, the wall becomes short and if > 12, the wall becomes slender.

Braced and Unbraced Concrete Walls:

Braced: If cross walls are arranged for the walls so as to they can bear lateral load and 2.5% of vertical load, then the wall is defined as braced. If not, the wall is called as unbraced wall.

Note: Other walls under special cases are,
i) Cantilever wall
ii) Shear walls – To withstand lateral loads [Handle flexure created because of lateral loading on the structure, depth is allowed along the transverse direction]
