Abstract: A door is constructed with a separate member joined to the door edge by a tongue-and-groove coupling and screws so as to be readily removable and replaceable. The separate member sustains the impacts imparted to the door by carts or wagons pushed past the door and can be readily replaced when damaged, thus avoiding replacement of the entire door. A flexible cover snaps over the outer surface of the separate member to add impact resistance and aesthetic appeal. Intumescent strips may be inserted inside or outside of the cover to enhance sealing between the door, and as adjacent door or door frame, thereby improving the fire resistance rating of the door. Accent strips or reveals of contrasting or complementary colors may be incorporated to add to the aesthetic appeal of the door. The door construction is of particular utility in schools, health care facilities and other institutions.

Abstract: Fire resistant door, glazing, and mullion frames include intumescent material at least partially embedded in the frame adjacent the door or glazing. Trim materials are positioned over the intumescent material to prevent tampering with and damage to the intumescent material while improving the aesthetic appearance of the frame. The jamb trim has a thickness that allows heat to be transmitted to the intumescent material in the event of a fire so that the intumescent material will expand and fill a clearance space between the frame and the door or glazing. The expanded intumescent material retards the passage of heat and, by sealing the clearance space, inhibits the transmission of smoke, flames and gases from one side of the door or glazing to the other. After expanding, the intumescent material will char and solidify, which may provide an added benefit of structural support for the door or glazing.

Abstract: A firestopping apparatus for providing a fire barrier in a construction barrier. The apparatus is comprised of a sleeve within which there are located intumescent pads that are oriented to form a confinement area therebetween to accommodate various penetrating members such as cables, conduits and the like that need to pass through the barrier. Upon sensing the heat from a fire, the intumescent pads seal around the penetrating members to prevent the fire from passing through the barrier. One or both of the intumescent pads is movable toward or away from the other so that the confinement area can be adjusted in size, that is, the confinement area can be increased in size to accommodate a large number of penetrating members of decreased to accommodate a lesser number. One or both of the intumescent pads may be biased in the direction toward decreasing the size of the confinement area.

Abstract: The invention relates to a right-angle connection in the grid of a suspended ceiling, between inverted T-beams having a vertical web extending between a bulb at the top and flanges at the bottom. A connector on the end of a cross beam hooks into a slot in the web of a main beam. The connector has a plastic encasement that forms abutments about a metallic core. The abutments position the connector within the slot in the web, and prevent further entry of the connector into the slot, under normal conditions. The plastic abutments melt away during a fire, so that the beam can expand longitudinally into the slot to relieve stresses in the beam, without the beam buckling. Ridges on the bottom of the metallic core that engage the web at the bottom of the slot, prevent pullback of the connector from the slot, during a fire, to prevent the ceiling from sagging or drooping.

Abstract: A fire in an enclosed space in an aircraft is, for example, visually detected early since smoke generated by a beginning fire is initially permitted to escape from the enclosed space. The enclosed space is, for example, an overhead luggage bin or a goods container holding food or freight. The smoke can pass through a flow passage either in the form of a gap or a leak between a lid and walls, or between a door and a door frame, or between walls and other walls joined together. Intumescent material is installed along the gaps or leaks and expands into the gaps or leaks when the fire has generated a temperature sufficient for causing the expansion of the intumescent material. Preferably a guide surface assures that the intumescent material expands into the gaps and leaks and cannot expand away from gaps and leaks.

Abstract: A fire stop assembly for bordering a conduit access through a building separation, includes a rigid body portion with an access opening with the access opening being adjustably closed to define a conduit fitting opening within the access opening. The remainder of the access opening is adjustably closed by a fire block arrangement comprising a lining of intumescent material on opposite sides of a conduit fitting opening and a series of non intumescent flame retardant members cooperating with the lining of intumescent material to close the remainder of said access opening. Preferably the non-intumescent flame retardant members are a series of plastic sleeves filled with mineral wool or other suitable insulation material. The sleeves and fill material are removable to adjust the opening size. The sleeves serve to protect the insulation material during the normal life of the fire stop assembly until a fire condition occurs.

Abstract: The heat dissipating beam is an I-beam with heavy-duty conduits placed in the upper left and lower right hand corners. These conduits would be clamped in place and would be linked together via suitable fittings when the beams are structurally arranged. The conduits would be tied into a common riser to a roof-mounted water storage tank, which would hold water or another fluid with heat dissipation qualities. A pump would also be attached to the water tank for replacing the fluid after a fire or similar incident in which deployment of the fluid into the beams would be necessary. When the conduits are filled with water, or another suitable liquid, the beam would be able to withstand exposure to a greater degree of heat before weakening and failing.
