Pigeon Loft: Rooftop Multipurpose Unit "Hatokotto"
Significantly contributes to shortening construction time and reducing the weight of pigeon coops! Furthermore, it enables labor savings through smooth workability!
"HATOCOT" is a product that has unitized the commonly referred to "pigeon coop" for rooftop slab penetrations. Pigeon coop construction requires many processes after the rooftop slab is poured, including layout marking, formwork, rebar placement, concrete pouring, formwork removal, waterproofing, and mortar finishing. However, by unitizing the pigeon coop, complicated construction can be simplified, and since there is no need for a curing period, work on rooftop waterproofing and plumbing installations can begin immediately after installation. Additionally, the weight of the pigeon coop can be confirmed, making the calculation of rooftop load capacity clearer. It has been about 30 years since its release! It can be widely used not only for new constructions but also for renovations and upgrades of air conditioning systems, and it has been adopted in over 15,000 sites. This pigeon coop generates no waste and is environmentally friendly. 【Features】 - Significant reduction in construction time - Contributes to labor savings on site - Lightweight compared to conventional methods - Easy maintenance for plumbing inspections and repairs - Contributes to waste elimination and environmental considerations on site - Made of FRC material, excellent in durability and strength - Applicable to various waterproofing methods - Easy waterproof repair work on rooftops *For more details, please contact us or refer to the catalog.

The Hatokotto consists of three units: upper, middle, and lower units. Upper unit: Removable! Easy to inspect and repair. Middle unit: By opening within the extraction surface dimensions, piping and ducts can be accessed. The skirt-shaped part covers the horizontal fixing part of the waterproof layer of the lower unit, preventing rain from blowing in. Lower unit: It has the function of fixing the connection of the rooftop slab and the rising part of the waterproof layer. In addition to being fixed to general concrete slabs with dedicated anchor bolts, it can also be installed on deck plates, ALC, and more.
