Principle of IKP Louvers

An opening rate of over 90%, with rainproof, snowproof, and soundproof features! There are also achievements with an opening rate of 110% to 120%!

The "IKP Louver" originated from the intrusion of rainwater blown up by the sea breeze through the intake louver of an emergency generator soundproof shelter installed at the coastline. It was designed to effectively prevent wind and rain without utilizing a large hood or significantly altering the exterior, while maintaining an opening ratio of over 90% and ensuring low air resistance. The key idea lies in the diversification of a large single-shaped hood. The evolution of the actual concept is illustrated in photos 1, 2, and 3. 【Basic Structure for Expanding Opening Ratio】 Figure 1 illustrates the key point of the concept. It effectively prevents rain from below against the inner vertical opening surface, while keeping the outer opening horizontal to allow for an expanded free volume.

[Construction Example] Station

We will vividly realize the image of the region through a variety of construction techniques.

We would like to introduce the construction case of a station handled by Okju. In the railway industry, pigeon damage to station buildings and platform roofs is a very serious problem. This time, West Japan Railway Company requested a finish using ceiling base materials, and as a result of development considerations, we adopted the "MB Louver," which can prevent pigeons from entering the ceiling interior. It is an extremely simple single-slope line louver composed of two types of components: the louver body using ceiling battens and the stringer. By selecting from several types of louver pitches, various expressions can be created, and if a specific pitch is chosen, it is also effective for pigeon prevention, allowing for a sharp ceiling design in places such as station buildings, platforms, and corridors, where movement lines should be considered. [Overview] ■ Name: JR Himeji Station / JR Okayama Station ■ Design: JR West Japan Consultants ■ Construction: Oitec Co., Ltd. / Obayashi Corporation JV ■ Construction Area: Platform Ceiling MB Louver *For more details, please refer to the PDF document or feel free to contact us.
