By the end of this meeting, expected student will be able to :

• Student can explain elementary floor construction and mount from wood along with its.

Learning Outcome

Bina Nusantara

• Items 1 : Elementary floor construction.• Items 2 : Floor level construction of wood• Items 3 : Link mains log Detail and log child.

Outline Items

Bina Nusantara

Floor represent pallet area an room as place execute all activity. From construction facet, floor divided to the two kinds of, that is:

* Elementary floor

Floor residing in and made to correlate direct above land of* Storey floor

Is made do not in direct correlation to floor.Floor have to can shoulder laboring burden and have to

be stiff enough, do not vibrate. Physically floor have to can exploit and look after natural condition of environment that happened for the requirement of dweller.

Burden Floor

Geology

7

Base have to be solid / ossify and stabilize and also flatten.

Geology have to free from organic materialss of.

Condensation / repair of ground earn with giving sand.

Bina Nusantara

In the situation land which is water level of its high land, land can improve with giving plastic sheet above repair of land is then piled up by sand, new of installation of its floor.

Cover of floor can made from natural stone, tiling of Pc, terrazzo, ceramic, wood, materials or carpet of synthetic other.

Bina Nusantara

• Garage or roadway, floor construction can be made as follows :

For Heavy Burden.

Bina Nusantara

10

For the construction of concrete block.

Bina Nusantara

For cover of ceramic materials.

Storey Floor

12

Floor storey construction consist of : • Floor area• Wall / floor logs• Columns / pillars.

Burden at floor :1. Weight alone : - Floor plate weight - Weight of floor cover

Bina Nusantara

13

2. Burden life weight : - People - Furniture / stationery - Rain

Burden at floor log : - Weight it self + Weight of floor plate Dead

load - burden good for at for the width of shouldered

area Life Load

Bina Nusantara

14

Burden at column - Roof burden - burden effect of total reactions of floor logs.

Burden at foundation - Accepted burden is itself column weight and

column.

Bina Nusantara

15

Besides dead load and live load also there are load effect of earthquake and wind. At calculation of structure often there are :•Fixed Load = dead load + live load .•Whereas Load = Fixed Load + Load effect of earthquake and wind.

Bina Nusantara

• Floor converged by wall.

16

Bina Nusantara

• Floor converged by columns (Mushroom construction)

17

Bina Nusantara

• Floor with its logs

Construction Materials

19

1. Floor storey construction can be made of :Entirely from same materials :

• pillar, log, floor from wood.• pillar, log, floor from steel.• pillar, log, floor from concrete.

2. Combination material with concrete and wood :• Pillar is from concrete, floor and log are from

wood• Pillar and logs are from concrete, floor is from

wood.

Bina Nusantara

3. Combination material with wood and steel :• Pillar is from steel, log and floor are from wood,

especial logs from steel.• Pillar and entire log from steel, only floor is made

of wood.

4. Materials concrete combination with steel, in general which is often used :

• Pillar from steel and concrete material• Floor from concrete material

20

Bina Nusantara

Election of materials for the construction of floor mount this depended from :

• Function / usefulness of itself building.• Structure form of itself building.• Location / place founding of building.

21

Bina Nusantara

• Dissociating rooms / chambers by leveling off.• Removing burdens at wall.• Supporting boundary wall which do not continue

downwards.• Adding stability a building with forming one unity

together with wall.• Preventing to creep echo voice• Weaken bound voice• Insulation to transfer of temperature.• Propagating the amount of burden wide of larger

ones.

Common Function of Floor Support.

22

Bina Nusantara

• Floor have to enough power.• Fulcrums at wall have to in such a manner so that

wide of supporting is big enough.• Yoke floor have to wall in such a manner so that

prevent limber wall.• Floor materials have to good quality and have to

earn to be done easily.• Floor have to easy treatment.• Construction have to earn well guaranted its

strength during old ones.

Floor Construction Condition

23

Bina Nusantara

Benefit :• Light materials, making/workmanship can be done

swiftly.• Wood price lower compared to other materials price.• Wood have insulation energy which do well by good

enough insulation energy and heat to echo voice and bound voice

• As place for attached easy channel.• Solving of floor, that way also installation of plafond

enough easy to and modestly.• Workmanship of repair and installations of

reinforcement can be done by easy.

Wood Floor Construction

24

Bina Nusantara

Its loss :• Stability a building with wooden floor is small.• Flammable wood.• Surface of floor scraggly and timeworn easy to,

till need sheating.• For high building, applying of wooden floor do not

be suggested.• Needed treatment so that wood do not light upon

white ants.• Size measure unfold limitedly.
