3 4 5 METHOD USED IN SETTING OUT


3 4 5 METHOD USED IN SETTING OUT

The 3 4 5 method is an accurate method use in Getting the Exact Square of a Plan instead of Using the Engineering Square which may not be accurate for a Longer Span. The 3 4 5 method is an application of the Pythagoras Theorem. i.e Forming right Angle. Most times, 2 or 3 people are involved in this.

 3 meters is Measure from the Parallel Line created, then 4 Meter Away from the First point forming a Right Angle, you use your Measuring tape to Confirm the distance between the 3m point noted at the parallel line and the 4m noted at the other line is 5m. Note that your Parallel line remains The same, you only shift the other line to form the right Angle.

HONEYCOMBS IN CONCRETE AND REMEDIES

Image
HONEYCOMBS IN CONCRETE AND REMEDIES Honeycombs  are hollow spaces and cavities left in concrete mass on a surface or inside the concrete mass where concrete could not reach. These look like honey bees nest. When concrete is poured into the formwork it does not just flow in like water and fill up the forms to the top. The concrete has to be vibrated for ease of flow and to form a uniform surface. If it is not vibrated properly it may leave voids exposing the aggregate. The surface on concrete appears as a rough, pitted with voids in concrete resulting incomplete filling with the gap between the aggregates of the concrete against the formwork. Such type of surface and texture on concrete resemblance like a Honeycomb in a beehive of Honey Bee. This scenario can happen on any structural element- Columns, Beams,, Lift Walls, Foundation of any type, etc. Honeycombs which are on sides are visible to naked eyes and can be detected easily as soon shuttering is removed. Honeycombs that are

Crank Bar in slab

Image
Crank Bar in  slab The slab is supported at two ends. The maximum tensile stress that is positive moments (sagging) acting in the middle of the slab and the maximum compressive stress that is negative moments (hogging) acting at both ends of the support. So bottom steel is required at the mid-span and top steel resists negative moments at the supports. A bent-up bar called a  crank bar  is provided to make RCC slab safe from compressive stresses. So crank bars are generally provided 1. To resist the negative bending moment (hogging). 2. To  resist shear force which is greater at supports. 3. To reduce the risk of brittle failure of slab-column connection. 4. To reduce the amount of steel used. 5. For the economization of materials.
