Fire Protection Kit for Cable Penetrations "Ichijikan-PK25 Kit" Launched

Background of Development

The Building Standard Law of Japan requires that all cabling and piping systems should be provided with fire spread prevention measures having a predetermined performance level to achieve a fire resistance period of one hour maximum, when they penetrates walls and floors that constitute fire control compartments of buildings.
Conventional fire control measures use fireproof boards made of calcium silicate and the like as a shuttering board for cable routes, and fill the opening between the cable and board using fireproof sealing materials. But this method poses the problems as described below.

1. Although hollow plasterboards are broadly used in most buildings recently, there have been no fireproof work procedures applicable to such boards.
2. Work contractors usually purchase a large-sized fireproof board, and cut out at the site a required portion fit to the actual size of the opening, letting the scrap pieces go to waste and generating the waste disposal costs.
3. When both walls and floors are to be worked simultaneously, material order placements and work procedures are likely to go wrong, since they use different materials and techniques.

Examples of installation (above: wall penetration, below: floor penetration)

To solve these problems, we have standardized the testing method for hollow walls, and brought into the market a convenient kit product. The product contains the required volume of the required material in a package, and is applicable to either hollow walls, concrete walls or floors with steel sleeves. Use of this product can reduce disposal costs of scrap pieces and waste, and at the same time can eliminate erroneous material order placements and work procedures, thereby achieving process simplification and work period reduction of field works together with cost reduction and work quality improvement.

Features of the Product

1. Applicable to hollow plasterboard walls
   Having acquired the accreditation PS060WL-0274 to cope with hollow plasterboard walls that are broadly used recently, this product is applicable to all the fireproof walls that are accredited from the Minister of Land, Infrastructure and Transportation.
2. All the necessary materials are contained in a package
   The product comes in ten varieties corresponding to the size of the penetration openings to be worked, and all the necessary materials for one penetration are contained in a single package. Thus, generation of scrap pieces and waste is curtailed, making this product environment friendly.
3. A kit product applicable to both walls and floors
   The same kit product can be used to both walls and floors equipped with a steel sleeve, eliminating the bothersome selection of materials and work procedures for the user.
4. Single-sided work is possible
   For the first time in the fireproof board work procedures applicable to hollow walls, the product permits finishing the work by installing the fireproof board only from the one side of a wall.
5. Lower costs than the conventional
   With its acquired accreditation for wall processing, this product enables reductions in materials used and simplification of work procedures than the conventional methods, thereby achieving a 40% reduction in the material and work costs.
