1. Method of understanding architectural drawing 1-9. Special terminology of construction (earthquake isolated structure)
Special building structure (earthquake isolated structure)
Most buildings, which have the earthquake resistance structure, stand on the ground. When theearthquake occurs, the building swings strongly because the earthquake force is transmitted on the grounddirectly.
The earthquake isolated building stands on the earthquake isolated facility, which is installed on theground. When the earthquake occurs, the building doesn't swing strongly because the earthquake force
is isolated by the isolated facility. The earthquake force, which is not isolated by the earthquake isolated
facility, is transmitted to the building slightly.

Earthquake isolated building

The earthquake isolated structure can decrease the damage of the building itself. But if the piping (duct)is damaged, as a result, if the lifeline is damaged, there is no earthquake isolated effect. In order to avoid
such a situation, the earthquake isolated fitting, which absorbs the large displacement by earthquake, should
be used for the piping (duct).
* The displacement is issued by the movement of earthquake isolated building when the earthquake occurs.

Fix at ground sideFix at building side

* The fix frame base should be installed near the earthquake isolated fitting in boththe building side and the ground side.

workshop drawing

5-1. Making process of smoke exhaust duct workshop drawing (1)5-1. Making process of smoke exhaust duct workshop drawing
Special attention points in order to make the drawing of smoke exhaust duct as fire and smoke protection
system are shown below.
* Pay attention to the different points from the air-conditioning duct or ventilation duct.
The workshop drawing in case of the smoke exhaust duct is often made from the design drawing as same as
in case of the air conditioning duct or ventilation duct. However, the smoke exhaust duct is concerned with"the human life", so decide carefully its route and size.
* In case of making the drawing, review the specification described in the design drawing again surely.
a) Confirmation of smoke exhaust typeThe smoke exhaust has some types, for example the natural type, mechanical type, pushing out type,pressurization type and others. So decide it based on the condition.
Natural smoke exhaust

Sub room
and others

Corridor

Mechanical smoke exhaust

Sub roomand others

Room in fireThis type exhausts the smoke by using the smoke buoyancy.

CorridorRoom in fireThis type exhausts the smoke by mechanical power withnatural outdoor air supplying from the lower part.

Pushing out smoke exhaust*

Sub roomand others

CorridorPressurization smoke protection and exhaust*

Sub roomand others

Room in fireThis type pushes out the smoke by mechanical power withoutdoor air supplying from lower part.

CorridorRoom in fireThis type prevents the smoke from invading to the fire fighting basesuch as the sub room of special emergency stairs by pressurization.

* In case of the 'pushing out type' and 'pressurization type', pay attention to the risk of strengthening the fireby the excess air supply. Besides, these types need the Minister's approval based on the Building StandardLaw, Article 38. In particular, in case of the 'pressurization type', pay attention to the difference in the scope
specification between the Fire Fighting Law and Building Standard Law. (Refer to the drawing below)
Pressurization type based on Fire Fighting Law(Fire department notification No.16 in 2009)

Sub roomand others

CorridorRoom in firePressurization type based on Building Standards
Law (Ministry of Land, Infrastructure, Transportand Tourism Fire notification No.1007 and 1008
revised in 2009)

Smoke exhaust system based on Building Standards Law(Building Standards Law regulation, Article 126.2)- 86 -b) Decision of smoke exhaust outlet
The natural type uses the smoke exhaust window installed by the building work as the smoke exhaust outlet, so
the air-conditioning workshop drawing does not describe it. The smoke exhaust workshop drawing describe theduct, damper, smoke exhaust outlet and others used in 'mechanical type', 'pushing out type', 'pressurization type'and others described above. (* Here, the general panel type smoke exhaust outlet is shown below.)

Panel type smoke exhaust outlet

Decision standard of smoke exhaust outlet size
- The air volume of smoke exhaust should be 1m3/min per 1m2 of the target area.
(1 target area should be maximum 500m2.)- The outlet air velocity of smoke exhaust outlet should be 10m/s or less.
- The minimum smoke exhaust outlet size should be 300mm x 300mm.
Effective area of smoke exhaust outlet

Air volume of smoke exhaust [Q]Outlet air velocity of smoke exhaust [V]×60s
Effective area of smoke exhaust outlet [A']Opening ratio of smoke exhaust outlet [ f ]Reference) Decision example of smoke exhaust outlet in case of mechanical smoke exhaust- Target area of smoke exhaust [S]: 15m × 12m (wall center) zone area is 180m2.
- Air volume of smoke exhaust [Q]: 180m2 × 1m3/min=180m3/min- Air velocity of smoke exhaust [V]: 7m/s- Opening ratio of smoke exhaust outlet [ f ] : 68%* The opening ratio of panel type smoke exhaust outlet differs depending on the manufacturer,so decide the smoke exhaust outlet after confirmation.
