Original decorative formwork construction method

Repair of adjacent building after demolition of existing structure
We supervised the pile construction work. The pile locations were confirmed in advance, and the EAZET method was used for the piles.
The key points of supervision were product inspection of the piles and
determination of the construction length. In other words, adjustments were
made if the actual conditions differed from the pre-construction ground
survey data.
Each pile has product information such as steel pipe strength written on
it.
After the pile construction was completed, earthworks began.
Simultaneously with the pile construction, a test fabrication of the RC external insulation decorative formwork (scaffold-free) method was carried out at the Yamaguchi factory.
Confirmation inspection of pile locations was carried out
steel plates were welded to the pile heads
foundation reinforcement work was carried ou
reinforcement inspection and intermediate inspection were completed,
foundation concrete was poured
In parallel with the curing of the foundation concrete, we are preparing
the custom-made exterior insulation panels for the first-floor exterior
walls.
I traveled to Tokuyama City, Yamaguchi Prefecture, to inspect the custom-made
exterior insulation panels.
Normally, in reinforced concrete houses, the concrete load during concrete pouring is supported from the outside by formwork and scaffolding pipes.
However, in this case, because the building was constructed right up to the property boundary, there was no space to erect scaffolding or scaffolding pipes.
Therefore, as an alternative, we specially ordered exterior insulation panels with support ribs (straight bulges) as shown above.
These panels serve three purposes: exterior insulation, formwork, and decorative finishing material.

This is a ready-made product, but its basic structure is as described above.
Ribs (straight, bulging sections) are added to withstand the weight of
the concrete during construction.
