摘要： PURPOSE:To make changing of working clothes unnecessary in case of movement between clean rooms of respective floors and reduce the space of clean rooms by a constitution wherein stairs, connecting respective clean rooms of a plurality of floors, are made by the structure of air shower. CONSTITUTION:Clean air flows through respective supplying paths 19 by connecting them to a clean air unit 23 provided at the upper part of a building 2 and is blown off downward from air nozzles 22 to flow it through the staires, thereafter, is sucked into return paths 18 to flow it through a return collective path 21. According to this constitution, the space of the stairs 4 is constituted so as to be the air shower as a whole. In case workers move between individual clean rooms of respective floors, they can move through the stairs 4 under wearing dust-proofing clothes without changing their clothes and working efficiency may be improved. Further, it is not necessary to provide air showers individually in the individual clean rooms 3 of respective floors, therefore, it may become favorable with regard to space.

摘要： PURPOSE:To improve a workability by filling a concrete into a space surrounded by an outer ring, an inner ring and a vertical rib, by placing a footing stiffener rib of the outer and inner rings below a bottom liner plate and by connecting an inner and outer ring girders one another. CONSTITUTION:During a normal operation, an accidental load and a seismic load are supported by an outer ring 1, an inner ring 2 and a vertical rib 8, and then are transferred to a basement concrete mat by a ring girder 7 and anchor bolts 6 through a stiffener rib 3. The stiffener rib 3 is placed underneath a bottom liner plate 10 and therefore no countermeasure against a rusting is required. Moreover, as no rib is provided in a suppression chamber, a workability and maintainability of works such as an anti-rusting painting work and a stainless steel plating work can be much improved.

摘要： PURPOSE:To be able to eliminate temp. imbalance even if local temp. imbalance due to the installation location of equipment etc. takes place ion one space by installing main air supply ducts under the floor of a room and guiding air upward from the floor or the room. CONSTITUTION:There is a room for which air conditioning is carried out on a floor plate 1. Under the plate 1 a ceiling plate 8 of a secondary room located directly under the room is installed with a specified space and a plurality of main air supply ducts 5 are installed in the space 10 between the plate 8 and the plate 1. This ducts 5 are connected with an air conditioner from which temp. controlled air is introduced with pressure into the ducts. Connecting pipes 62 and outlet holes 11 which are connected with the bottom of the ducts 5 and used for supplying air into the secondary room from the plate 8 of the secondary room and a part of air in the ducts 5 is supplied to the secondary room from the holes 11. A plurality of branched ducts 4 are connected with the upper surfaces of the ducts 5 and the plate 1 has grooves 2 elongated lengthwise and crosswise and in this grooves 2 opening holes 3 of which number corresponds to the number of the ducts 4 are bored.

摘要： PURPOSE:To enable miniturizing dcuts which connect an air conditioner and each room and reduce occupied space by re-circulating exhaust air which is purified again for specified zones in addition to re-circulation of air-conditioned air from an air conditioner. CONSTITUTION:A part of air-conditioned air is blown off from blow-off holes 21a, 21b into equipment arranged zones 13 in a room and flows into exhaust holes 32 or exhaust holes 28 in an operation zone 15. Of this air, the air flowing through the exhaust holes 32 flows into maintenance zones 16 and most part of the air flows into an air mix adjusting device 34 where the air is mixed with air-conditioned air at specified ratio through ducts 33 and then is blown off again into the equipment arranged zones 13 in the room through fans 20a, 20b and filters 19a, 19b from blow-off holes 21a, 21b. As mentioned above, for the equipment arranged zones 13, exhaust air which is purified again by air purifiers 18a, 18b is circulated and therefore, purification is promoted by re-purification and highly purified air is let flow.
