摘要： PROBLEM TO BE SOLVED: To provide a light-weight fire or smoke-fire shutter sufficiently resisting air pressure, etc., at the time of a fire occurrence, capable of surely preventing the leakage of a smoke and a flame and having a simple structure. SOLUTION: A sealing piece 22c consisting of fire-resisting cloth is installed to a section corresponding to a surface on at least one side of the upper side, left side and right side of a shielding curtain 13 composed of the fire-resisting cloth, an edge section 22c1 on the free end side of the sealing piece 22c is brought into contact with the shielding curtain 13, and the upper side, left side and right side of the shielding curtain 13 are sealed. Supporters 24a, 24a receiving inward force working to a guide bar 23 for the guide apparatus of the shielding curtain 13 through the shielding curtain 13 are mounted into the channel-shaped vertical member 21 corresponding to the upper section of the guide bar 23. Accordingly, the guide bar is not bent inwards even when the force of air pressure, etc., works to the shielding curtain because there are supporters, and the leakage of a smoke and a flame from the periphery of the shielding curtain can be prevented because there is the sealing piece.

摘要： PROBLEM TO BE SOLVED: To easily remove a slate, enhance working efficiency, and reduce cost when asbestos with slate is removed by using a water jet nozzle.
SOLUTION: A cutting device such as a water jet nozzle 3 is disposed in a cylindrical structure 7 of reinforced concrete structure. A liner material such as a slate 9 and a material joining the liner material to a structure are cut off in block shapes by moving the cutting device in the circumferential direction and the vertical direction. The jetting direction of jet water from the water jet nozzle 3 is set to the diagonal downward. While rotating and lowering the nozzle, the jet water is sprayed to only the portion of the joining material from the diagonal upper direction to the diagonal lower direction to remove the joining material together with the boundary surface of reinforced concrete. Consequently, the liner material to which the removed joining material is adhered can be removed by falling it for each block by its own weight together with the material joining the liner material to the structure.

摘要： PROBLEM TO BE SOLVED: To prevent a chain from being loosened without changing the positions of a shaft and a switch by connecting the shaft and the switch with a pulley mechanism, fitting them to a bracket, and rotating a support member in response to the winding of the shaft. SOLUTION: A fire-protective shutter 10 is installed above a ceiling 15 by a plate-like bracket 14. The bracket 14 is rotatably fitted to the fulcrum 21 of a support member 19 fixed to the structural body 18 of a building. The bracket 14 is provided with a shaft 12 and a switch 26, and a chain 34 is suspended and connected between the shaft 12 and the switch 26. The position of the axis of the shaft 12 is changed relatively to a receiver 36 according to the wound state of a fire-resisting sheet 11, however it is allowed by the rotation of the bracket 14. The positions of the shaft 12 and the switch 26 are not changed, the chain 34 is not loosened, and no unnecessary tension occurs.

摘要： PROBLEM TO BE SOLVED: To improve the function of an emergency exit for a shutter curtain by attracting a door body made of the same fire-resistive sheet as the curtain to the emergency exit by a bonded magnet. SOLUTION: The upper end section of a door body 3 consisting of the same fire-resistive sheet as a shutter curtain 1 is sewn at the upper end part of an emergency exit 2 bored at the lower end part of the curtain 1, and the door body 3 is installed the emergency exit 2 in a freely open-close manner. Bonded magnets 7, 11 are mounted at the left-right edge parts 4, 5 and lower edge section 6 of the emergency exit 2 and bag sections set up at the left-right edge parts 8, 9 and lower edge section 10 of the door body 3 by housing, etc., respectively, and the emergency exit 2 is closed by the door body 3 by the attraction of the bonded magnets. Fire-resistive Velcroes are juxtaposed near the magnets 7, 11, and the opening of the emergency exit 2 is prevented even when the attractive force of the magnets 7, 11 is lowered at a high temperature. Accordingly, the emergency exit is opened and a man can escape even when the man fails to escape while smoke and a flame can be interrupted because no clearance is formed in the emergency exit even when the shutter curtain is deflected by hot air.

摘要： PROBLEM TO BE SOLVED: To improve performance by executing specified impregnating material and coating material onto silica cloth as a base material, in which SiO2 content is specified. SOLUTION: A silica-cloth base material obtained by sateen weaving silica fiber yarn, in which content extends over 96wt.% or more, is impregnated with a PTFE dispersion, and the dispersion is dried. One surface of the base material is coated with chlorosulfonated polyethylene, and a fire-resistive sheet 1 is formed. A plurality of the sheets 1 are sewn, and a shutter curtain 5 having a desired shape is molded. Accordingly, the base material can correspond to a high temperature of approximately 1000 deg.C while the generation of cracks in the sheet can be prevented by the coating of chlorosulfonated polyethylene when the shutter curtain is exposed to a flame, frictional damage at a time when the shutter is closed at the time of a fire can be obviated by the impregnation of the PTFE dispersion, and the shutter can be manufactured at comparatively low cost.

摘要： PROBLEM TO BE SOLVED: To provide fire-resistance test object structure and a fire-resistance testing method capable of executing a "buckling test", in a fire resistance qualification test for a steel beam provided along a fire-resistant wall. SOLUTION: In this test object, the steel beam 10 is surrounded with the fire-resistant wall 51, a floor sheet 62 provided in an upper part of an upper flange 11 in the steel beam 10, and a fire-resistant coating material 20 for coating an anti-fire-resistant wall side of the steel beam and a lower flange 14 side of the steel beam. The floor sheet 62 is extended toward the anti-fire-resistant wall side. The gravity center position of the test object is thereby positioned on the steel beam 10, in detail, on a substantially vertical straight line passing the center of a web 16 in the steel beam 10.
