Lintel & its Types

What is Lintel?
A lintel is a horizontal member which is placed across the openings like doors, windows etc. It takes the load coming from the structure aboveit and gives support. It is also a type beam, the width of which is equal to the width of wall, and the ends of which are built into the wall.
These are very easy to construct as compared to arches.Bearing of lintel:The bearing provided should be the minimum of following 3 cases.
i) 10 cm.
ii) Height of lintel beam
iii) 1/10thto 1/12th of span of the lintel.

Classification of lintels:Lintels are classified based on the material of construction as:
1. Timber
2. Stone
3. Brick
4. Steel
5. Reinforced Concrete

Shear Force & Bending Moment Diagram of Simply Supported Beam

Shear force and bending moment diagram of simply supported beam can be drawn by first calculating value of shear force and bending moment. Shear force and bending moment values are calculated at supports and  at points where load varies.

SIMPLY SUPPORTED BEAM WITH POINT LOAD EXAMPLE

Draw shear force and bending moment diagram of simply supported beam carrying point load. As shown in figure below.

Solution

First find reactions of simply supported beam.

Both of the reactions will be equal. Since, beam is symmetrical. i.e.,

R1 = R2 = W/2 = 1000 kg.

Now find value of shear force at point A, B and C.

When simply supported beam is carrying point loads. Then find shear force value in sections. Shear force value will remain same up to point load. Value of shear force at point load changes and remain same until any other point load come into action.

Shear force between ( A – B ) = S.F (A-B) = 1000 kg

Shear force between (B – C) = S.F (B -C) = 1000 – 2000

S.F (B – C) = – 1000 kg.

Shear Force Diagram

Bending Moment

In case of simply supported beam, bending moment will be zero at supports. And it will be maximum where shear force is zero.

Bending moment at Point A and C = M(A) = M(C) = 0

Bending moment at point B = M(B) = R1 x Distance of R1 from point B.

Bending moment at point B = M (B) = 1000 x 2 = 2000 kg.m

Bending Moment Diagram

SIMPLY SUPPORT BEAM WITH UDL & POINT LOAD EXAMPLE

Draw shear force and bending moment diagram of simply supported beam carrying uniform distributed load and point loads. As shown in figure.

Solution

First find reactions R1 and R2 of simply supported beam.

Reactions will be equal. Since, beam is symmetrical.

R1 = R2 = W/2 = (600 +600 + 200 x4)/2 = 1000kg

Hence, R1 = R2 = 1000 kg.

Shear Force

Shear force between  section A – B = S.F (A – B) = 1000 kg.

Shear force at right side of point B = S.F (B) = 1000 – 600

S. F (B) right = 400 kg.

Now shear force at left side of point C.Because of uniform distributed load, value of shear continuously varies from point B to C.

Shear force at point C (Left) = S.F (L) = 400 – (200×4)

Shear force at point C (Left) = S.F (L) = -400 kg

Shear force between section C – D = S.F (C-D) = -400 – 600

Shear force between section C – D = S.F (C-D) = -1000 kg.

Shear Force Diagram

From Shear force, one can see;

• Shear force is maximum at point A and remain same until point load.
• At point B shear force value decreases, because of point load.
• From B to C shear force continuously decreases, because of udl.
• At point C shear force gradually falls, because of point load.
• From point C to D, shear force remain same, because no other point load is acting in this range.

Bending Moment

 B.M WILL BE ZERO AT SUPPORTS. I.E.,

M(A) = M(D) = 0

B.M at points B and C = M(B) = M(C) = 1000 x2 = 200 kg.m

Now, how to find maximum bending moment?

Bending moment will be maximum at point, where shear force is zero.  Hence, bending moment will be maximum at mid point.

M (max) = 1000×4 – 600×2 -200×2(2/2)

M (max) = 2400 kg.m

Simple Steps In Construction of Residential Building

Steps In Construction of Residential Building

The following steps are followed in residential project construction;

Construction of residential building required following paper work before the start of actual construction:-

1. Preparation of drawings as per requirements of consumers.
2. Estimation of material cost, labor cost & contingencies.
3. Approval of drawings & estimates from Client.
4. Approval of drawings from City Development Authority. It is most important because residential building drawings should meet the authority defined rules.
5. Start of construction work either through contractor or labor hired on daily basis.
6. Marking of plot boundaries.
7. Cleaning of plot.
8. Preparation of site layout as per drawing.

After the completion of documentation work, the actual construction on plot begins. Following are the steps;

EARTH WORK

Generally excavation is carried out for the construction of wall foundations. Excavation should be carried out as per the drawings defined lengths & widths. After excavation, layout the foundation and backfill the remaining excavated area around foundation with soil.

Floor levels of residential buildings are higher than the natural ground level. Fill the area with soil up to floor levels and compact the soil. Now earth work of residential building is finished.

Earthwork for Footing

CONCRETE WORK IN FOUNDATION

It is very necessary to check the levels of foundation before concrete work. There are patches where excavated depth slightly exceeds and vice versa. Level the foundation base to same level. Now pour the concrete as per drawing specs. Generally concrete of ratio 1:4:8 is used for foundation. Sometimes it is even 1:5:10 or 1:6:20.

Here 1:4:8 means;

1 part cement per cubic

4 parts of sand per cubic

8 parts of coarse aggregates

Depth of foundation varies from 9” to 18” and normally for most of the cases it is considered as 12’’ depth. Keep foundation width equals to its depth.

DAMP PROOF COARSE (D.P.C)

To protect walls from moisture, a layer of damp proof coarse material is laid down at floor level. Thickness of this concrete layer is 0f 1 inch. Material of damp proof coarse layer consists of concrete ratio 1:1.5:3 with a mixture of water proof material 1kg/bag.

MASONRY WORK

Masonry work is carried out with cement mortar. Cement mortar is a mixture of cement & sand. Ratio of cement mortar varies from 1:4 to 1:6. Here (1:6) mean, 1 part cement and 6 parts of sand. Dampen about 25 bricks with a hose pipe and clean away all loose dirt from the top of footing and moisten about a meter of surface at one end of the foundation with the hose pipe. Throw a mortar line just behind the threaded level line and lay bricks on the mortar bed. Make sure bricks exactly follow the threaded horizontal level line.

Brickwork

LINTEL

Masonry work of buildings is carried out in one go till roof. Openings for windows & doors are left during masonry works. Reinforced cement concrete beams are laid down on the top of openings. So, those loads of structure above openings not directly come on to the door frames.

Lintel beam-- above window

ROOFING

Roof slab of building is poured after completion of masonry works. Now a days, roofing is of reinforced cement concrete slab. Slab thickness & reinforcement details should be according to approved drawings.

PLASTERING & POINTING

Form work is removed after 14 days of slab pouring. Now plaster work begins. Mortar for plaster work is generally of 1:3 or 1:4 is used. Thickness of plaster layer should not be more than 0.75inch. Cure the surface about 7 days. So that, plaster gain proper strength.

Generally, internal walls of buildings are covered with plastered layer and external walls with pointing. It is better plaster the external walls rather than pointing.

Plastering

DOORS & WINDOWS

Traditionally, doors and windows of woods are used. But, steel & aluminum is also not a bad choice. In case of wooden doors & windows, frames are fixed in walls during masonry work. Panels are then fixed with hinges after plaster work. Steel and aluminum doors are fixed after completion of paint work.

SERVICES

Services are very important for every single house. Different types of services are provided during construction. These are Electricity supply, gas supply, water supply, sanitary etc. Conduits for electric supply are fixed in walls before plastering. Similarly water supply and sanitary lines are also laid before pouring of building floor. Note that gas lines are not fixed in walls or slabs. Gas line remains open in air.

Vastu for Plots

Vastu for Plots

Considering this points in Vastu for Plots;
• Plot should be square of rectangular in shape. Square would be best. If it is rectangle then the ratio of length to breadth should be 1:2 and not more than that. • The ground level should be higher in South & West rather than North and East. • Plots facing North or East are better than those facing South or West. • A canal, a lake, river, nallah, a big well or pond should be in north or east only. • Heavy construction or mountains should be in west or south of the plot. • There should not be any big tree in north or east of the plot. • There should not be any pit or well in south or west direction. • All four corners should be at 90 degree (set Square). If only north east is extended i.e. if it is less than 90 degree, it will do. • All rain water should flow from south to north and west to east. • South west should be highest & north east should be lowest in level. • If all the corners are not at 90 degree then we should correct it before starting the construction. • If the dead end of a road is coming in our plot then it should be taken care of because some are good & some are bad. This is called vidhee soola. • Their should not be any hills or mountains in east or north side of your plot. • At the time of purchasing the adjacent plot purchase only in east, north or north-east plots. Never purchase adjacent plot in south or west or accept if even if offered for free.
