- Short construction period!
- Seismic reinforcement completed with only external work!
- Assigned method certification technical personnel to the headquarters (Nagoya), Tokyo branch, and Osaka branch!
As a member of the Pitacolumn Construction Method Association, we have accumulated a track record of construction achievements. Please consider us as a reliable seismic reinforcement method.
● We have assigned two certified "construction managers" in Tokyo, four in Nagoya, and three in Osaka to respond to requests from a wide area.
● The Pitacolumn (Plate Included concrete Tightly Attached column) method is one of the seismic reinforcement methods that allows reinforcement work to be carried out while the building is in use.
● The construction method involves first installing post-installed anchors at regular intervals on the existing columns to be reinforced. Steel plates (plates) are then attached to the anchors installed at a position 10 cm from the existing columns. Additionally, elliptical shear reinforcement bars (hoops) are distributed at regular intervals around these steel plates. Finally, approximately 20 cm thick concrete is poured to encase these elements, completing the work. The basic concept of Pitacolumn is to perform seismic reinforcement work without entering the interior of the building.
