[Catalog Revision] Achieving labor-saving by modularizing pigeon coops! Contributing to significant shortening of construction time, smooth workability, and reduction of rooftop load weight.
"Hato Kotto" is a product that has been modularized from the commonly known "pigeon coop" of the rooftop slab penetration. The construction of the pigeon coop requires many processes such as marking, formwork, rebar installation, concrete pouring, formwork removal, waterproofing, and mortar finishing after the rooftop slab is poured. However, by modularizing the pigeon coop, complicated construction can be omitted, and since there is no need for a curing period, work on rooftop waterproofing and plumbing can begin immediately after installation. Additionally, the weight of the pigeon coop can be confirmed, making the calculation of the rooftop load clearer. For over 35 years since its release, it has been widely used not only in new constructions but also in renovations and upgrades of air conditioning systems, being adopted in more than 15,000 sites. 【Features】 - Significant reduction in construction time - Prevention of falls and rainwater intrusion during construction - Easy maintenance for inspection, repair, and manufacturing - Suitable for renovations and expansions of equipment requiring rooftop slab penetration - Made of FRC material, it has excellent freeze-thaw resistance, durability, and strength, with low absorption and lightweight properties.
