Takamatsu Corporation’s Commitment to Architecture (Monozukuri)

Why are Takamatsu Corporation’s buildings resistant to earthquakes? This is a showcase of some of the construction knowledge and expertise that we have built to maintain our superiority in the rental housing market and to generate stable income over the long term.

Earthquake resistance, base isolation, and vibration control

Our reinforced-concrete buildings meet stricter earthquake-proofing standards than those stipulated under the Building Standard Act.
We also undertake measures against torrential rain, such as by raising the floor level, etc.

Preparing for earthquakes

Takamatsu Corporation standards

Our properties are designed and constructed at 1.15 times the earthquake resistance performance specified by the Building Standards Act, and we aim to create sturdy buildings that prevent damage in earthquakes with the seismic intensity of 6 and will not collapse in earthquakes with a seismic intensity of around 7.

Preparing for floods

Set the first floor level higher

Set the first floor level higher

Raising the height of floors in the entrance halls and residential units from the ground reduces flood damage to the building.

Backflow prevention valve

If backflow from the main sewage is anticipated due to torrential rain, we install a backflow prevention valve to prevent backflow from the main sewage.

Reinforced concrete structure resistant to tsunamis

According to an investigation into the Tohoku Region Pacific Coast Earthquake, reinforced concrete structures have been held up as effective structures against tsunamis.

Preparing for fires

with fire-spread-prevention functionality

We take all possible measures to prevent the fire spreading in the unlikely event of a fire.

So to prevent a fire that has occurred on a lower floor from spreading to the upper floors via the water distribution pipes that pass through the concrete floor, we take suitable measures depending on the building such as by using collecting pipes with fire spreading prevention capability to prevent flames, or using a non-combustible material in the vertical pipes connected to the lower floors.

A water-to-cement ratio

A water-to-cement ratio of 50% or less to increase durability

The water-to-cement ratio is the weight ratio of water to cement when making concrete. It is generally said to be 50% to 65%.
The smaller the water-to-cement ratio (the less water), the better the durability. In order to prevent the neutralization of concrete, we have increased the amount of cement and established a standard of a water-to-cement ratio of 50% or less.

Prevention of wall cracks caused by earthquakes

gNon-structural wallsh before 1997 had no structural strength and were prone to cracking during an earthquake. However, since the 1997 revisions to the legal standards, space has been added between the edges of non-structural walls and supporting columns to reduce the risk of wall cracking.

Competitive Apartments

We offer the construction of competitive apartments backed by our 100-year track record. Maintaining a high occupancy rate is the most important factor for stable rental management.

Comfortable space

Sound environment

Sound or noise can be a major problem in housing complexes. A design that blocks sound from the outside and prevents sound leakage from within makes for more comfortable living. We design sound insulation with the strictest possible standards in the industry.

Security design

Takamatsu Corporation’s basic security design

An appropriate security design is incorporated into each residential units and building common areas from the design stage. Piping is installed beforehand so that optional security cameras can be installed.
