Further preferably, these ribs 13, 14 are configured in sawtooth shape, and are engaged with each other when a plurality of fire hoses 10 are gathered together. COPYRIGHT: (C)2008,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a material for piping installation by which a covering pipe having the size suitable for an opening diameter of the piping installation can be arranged. SOLUTION: A tabular material 10 for the piping installation 40 comprises a first layer 11 including thin linear-like plates 14 which are arranged in sequence in a manner that longer side faces of the plates 14 are arranged side by side leaving spaces 15, a second layer 13 made of an elastic material, and an intermediate layer 12 arranged between the first layer 11 and the second layer 13. It is preferable that the intermediate layer 12 is formed of a woven material of a glass-fiber or metal, preferably, having low stretching property. The elastic material of the second layer 13 is an elastic covering film, and preferably is an expansible covering film material. Each of the plates 14 is made of a metal, and preferably formed of a thin steel plate. The flat plate material is formed of the material which can be cut and has no joint.

Abstract:
PROBLEM TO BE SOLVED: To provide a fire prevention duct shutter which can be quickly and easily attached to a duct. SOLUTION: This shutter to shut a duct 30 upon a fire and is provided with a housing 11 and a storage part 17 formed to store a duct 30. A cutting and shutting element 20 enabled to move from the housing 11 to the storage part 17 so as to cut in the duct 30 upon a fire by a drive means 28 is set in the housing 11, In the housing 11, the opposite side to the cutting and shutting element 20 in the duct shutter 10 having a fixing part 29 for fixing by a fixing element is opened and at least one stopper part 15 is set. At least one counter stopper part 25 to move linked to the stopper part 15 is set in the cutting and shutting part 20 so as to define a shutting position 42 of the cutting and shutting element 20.

Abstract:
PROBLEM TO BE SOLVED: To provide a two-component foaming system with extended fireproof time, and excellent in heat insulating properties and mechanical properties. SOLUTION: The system comprises (A) a polyol component comprising at least a polyol containing an aqueous polymer dispersing agent, in some instances a catalyst for reaction of the polyol with a polyisocyanate, water and/or a propellant based on a compressed or liquefied gas, as foaming agent, and (B) the polyisocyanate component containing at least a polyisocyanate. The invention describes the two-component foaming system for construction foams, the molar ratio of one or more than one polyols to one or more than one polyisocyanates in that case, is adjusted to 1:5 to 10:1 preferably 1:1 to 2:1 based on OH-group of the polyol to isocyanate group of the polyisocyanate.

Abstract:
In a method for installing a firestop means (14) or insulation having a firestop effect, on a line (12) or pipe, whereby the firestop means (14) or the insulation having a firestop effect is placed, especially wrapped, completely around the line (12) or pipe, in the circumferential direction (U), it is provided that a flexible adhesive tape (16) containing heat-resistant fibers (18) in its lengthwise direction (L) is wrapped in the circumferential direction (U) of the line (12) or pipe completely around the firestop means (14) or the insulation having a firestop effect.
Abstract:
A fire-prevention sleeve including a fire-prevention additive is embodied as a rectangular strip having a plurality of notches along only one longitudinal side, whereby neighboring flaps are formed. The notches are embodied perpendicularly in reference to the longitudinal extension of the strip, whereby the flaps are oriented perpendicularly thereto. The sleeve is positionable around installations guided through ceiling passages, whereby flaps may be bent perpendicular to the direction of extension of the installation. When the fire-prevention sleeve is inserted in the gap between the installation and ceiling passage, the flaps are bent backwards to form a pocket sealing the gap at its bottom.
