Construction Tools List for Building Construction
Some important construction tools and their uses are listed below:
Bolster :Bolster is like chisel but it is used to cut bricks. Its cutting edge is wider than the
width of brick. It is useful for accurate cutting of bricks.
Boning Rods : Boning rods are made of wood and they are T shape.
They are used to level the excavated trench throughout its length.
Minimum three boning rods are used to level the trench surface.
Brick Hammer : Brick hammer is used to cut the
bricks and also used to push the bricks if they come
out of the course line.
Bump Cutter :Bump cutter is used to level the
concrete surfaces like concrete floors, foundations etc. It is also called screed.
Chain Lewis and Pin Lewis
Chain lewis and pin lewis are two different tools which are used to lift heavy
stones especially in the construction of stone masonry.
Chisel :Chisel is generally used in wood work and this must
be useful to remove the concrete bumps or excess
concrete in hardened surface.
Circular Saw : Circular saw used to cut the wood boards,
frames etc. It is used when accurate cutting is required in
less time. It is safer than hand saw.
Concrete Mixer: Concrete mixer is machine which
mixes the ingredients water,
fine aggregate, coarse aggregate and
cement to deliver
the perfectly mixed concrete.
Crowbar
Crowbar is used for digging the ground
and to remove the roots of trees in
the ground, nails etc.
Digging Bar: Digging bar is solid metal rod with pin
shape at the bottom. It is also used to dig the
hard surfaces of ground.
Drill Machine:
Drill machine is used to make holes in
the walls, slabs, doors, window frames etc.
End Frames :Their use is similar to the line
and pins. But instead of pins, L shaped frames are used at the end
of thread which hold the brick work effectively and level the
alignment accurately.
Float : Float is made of wood which is used
to smoothen the plastered concrete surface. It contains
handle on its top and smooth wooden surface on its bottom.
Gloves
Gloves are required to prevent the hands from direct
contact with cement, paints etc. and to avoid injury
while using machines, tools etc.
Hand Saw : Hand saw is used to cut the wood
materials like doors, windows, slab panels etc.
Head Pan :Head pan is made of iron which is used to
lift the excavated soil or cement or concrete to the
working site etc. it is more commonly used in
construction sites.
Hoe : Hoe is also used to excavate the soil but
in this case the metal plate is provided with
acute angle to the wooden handle.
Jack Plane
Jack plane is used in the wood work to
smoothen the surface of doors and
windows etc.
Ladder : Ladder is also required in construction works. To check slab work, to transport
material to the higher floors, to paint the walls etc.
Line and Pins: Line and pins consists a thread whose ends
are connected with two solid metal rods with pin points.
It is used to level the alignment of brick course while
brick laying.
Mason’s Square: Mason’s square is used to achieve perfect right angle at the corner
of masonry wall. It is “L” shape. First course is laid properly using Mason’s square
then based on the first, remaining layers of bricks are set out.
Measuring Box: Measuring box is used to measure the quantity of sand
and aggregate used for making concrete. It is of fixed dimensions so,
aggregate need not to be weighted for every time. The general
dimensions of a measuring box are 300mm X 300mm X 400mm (length x
width x depth). The volume of measuring box is generally 1 Cubic Feet,
which makes it easy to measure concrete ratio or mortar ratio.
Measuring Tape : Measuring tape is used to check
the thickness, length, widths of masonry walls,
foundation beds, excavated trenches etc.
Measuring Wheel : Measuring wheel is used to
measure the distances or lengths. It contains a wheel
of known diameter, which record the no.of complete revolutions from
which the distance can be measured. It makes the work easier.
Pick Axe : Pick axe is used to excavate the soil. It is more suitable for
hard soil which is quite difficult to dig with spade or hoe.
Plumb Bob
Plumb bob is used to check the verticality of structures.
It contains a solid metal bob connected to the end of a
thread. It is also used inn surveying to level the instrument
position.
Plumb Rule
Plumb rule is used to check the vertical line of wall whether it is perfect vertical or not. It
contains a straight wood board with uniform edges. On its center a groove is provided in
which plumb bob is situated. When the rule is placed vertically with the wall the plumb bob
should be in the groove line otherwise the wall will not be vertical.
Polisher:Polisher is used to smoothen the surface of tiles,
wood works etc. The smoothening makes them shine and the
process is called polishing.
Putty Knife: Putty knife is used level the
putty finishing and also used to reduce
the thickness of finish when it is more
thick.
Earth Rammer : After the excavation of ground,
the lower surface may be uneven. To level the
surface earth rammer is used. It contains big square
shaped block at its end with which the ground is
leveled.
Rubber Boots : During construction works,
legs may damage due to contact with chemical
materials like cement or physical accidents. So,
for safety rubber shoes are required.
Safety Glasses : To prevent the eyes from dust,
chemical actions of materials etc. safety glasses should be
maintained.
Safety Helmet :The safety helmet should be necessary in construction works.
Any material or structure may fall from height during construction work. So, to protect
the head from injury or any fatal accident, this safety helmet should be used.
Sand Screen Machine : The fine aggregate used in concrete should
not contain impurities or coarse particles. The sand screen machine
is used to screen the sand or fine aggregate before mixing it with
concrete. This screen is also used for screening fine sand for
plastering work.
Scratchers : Plastering of a surface is carried out layer wise.
Minimum 2 coats are necessary for plastering. To provide the good bond
between the coats, bottom layer is scratched with a tool called scratchers.
Sledge Hammer: Sledge hammer is used when the ground
is hard and contains rock layers. A large weighted metal head
is provided at the wooden handle with which hard layers
can be cracked, which makes easy for digging.
Spade
Spade is used to dig the soil for foundation trenches etc. It contains metal plate
at the end of long wooden handle.
Spirit Level : Spirit level is made of wood or hard
plastic with bubble tube in the middle. The bubble
tube is filled with alcohol partially. So, the air
bubble is formed in it. Spirit level is used in brick
masonry to check the level of the surface. The spirit level is placed on surface and bubble is checked. The surface is
leveled when the bubble in the tube settles at middle of tube.
Straight Edge Brushes :Straight edge brushes are used to provide
finishing to the plastered surface especially at corners and edges of
walls.
Tile Cutter: Tile cutter is used to cut the tiles. Sometimes, normal tile size is larger than
required at the corners where floor meets the wall in that case tile cutter is useful.
Trowel:Trowel is used to lift and apply the cement
mortar in small quantities. It is made of steel and
wooden handle is provided for holding. The ends of
trowel may be pointed or bull nosed.
Vibrator :Vibrator is used to compact the
concrete by this the air gaps are filled with water
and workability varies without adding water to
it.
Wedge is a small hard metal blade which is used to
cut the rock surfaces with the help of sledge hammer.
Wheel Barrow : Wheel barrow is used to transport bulk weights of materials like
cement, sand, concrete mix etc. it contains one or two wheels at its front and
two handles at its back which are used to push the wheel barrow.
