摘要:
A method and system for achieving compliance for a fire-rated door assembly. To comply with fire rated door assembly codes and compliance, all components, including hardware must be listed and labeled by a certification agency, such as Underwriters Laboratories (UL). The disclosure may include a hardware preparation filler solution which allows fire-rated doors to maintain fire rating and compliance when removing or modifying hardware, or converting between hardware types.

A fire rated door includes a core, a first decorative panel and a second decorative panel. The core includes: (a) a fire resistant center panel having a bottom, a top, a first side, a second side, a first end and a second end, wherein the fire resistant center panel is made of a first fire resistant material, and (b) an extruded fire resistant border attached to the first side, the second side, the first end and the second end of the fire resistant center panel, wherein the extruded fire resistant border is made of a second fire resistant material having a higher density than the first fire resistant material. The first decorative panel is attached to the top of the fire resistant center panel and the extruded fire resistant border. The second decorative panel is attached to the bottom of the fire resistant center panel and the extruded fire resistant border.

Using integrally formed stiles on skins of sheet molded plastics (thermosetting) employed to form the exterior surfaces of a synthetic door having sheets of reinforcing materials adhered to the inner surface of each of the skins, the skins can be connected through the integral stiles and slats of a fire proof materials can be affixed to these stiles and rails closing the top and bottom opening between the skins to increase the fire resistance of the resulting door when the core is filled with a phenolic foam. The structure described reduces the weight of the resulting door and places the fire resistant materials around the door edges which are the most susceptible to failure during a fire while structurally tying the slats together through the sheets of carbon fiber or fiberglass disposed on the inner surfaces of the skins whereby failure (disintegration) of the skins during a fire will not lead to a collapse of the door as with some prior art door structures. A slat of polyvinyl chloride can be employed to cover the fire proof slats so the door edges can be trimmed so it will fit into the door frame and the edges will be pleasingly attractive.

A panel-sealing and securing system for securing a panel to a mullion coupled with weather seal pressure gaskets for sealing exterior joints under high wind velocity. The mullion is formed in one piece or in two halves of a split mullion which occurs at the joint between multiple pre-fabricated units of a unitized grid system. The mullion has a concealed front corner cavity adjacent to panel for installing the panel-sealing and securing system. For weather sealing, elastic pressure gaskets and expansion joints comprising panel gasket seals at a joint between the panel and the mullion and mullion gasket seals at a joint between the two halves of split mullion where a unitized split mullion system is used. To securing the panel to the mullion and allow for thermal expansion movement of the panel, two segments formed in one piece or in two hinge connected pieces include a gasket holder segment and a spacer plate segment. A retainer may be in the form of a screw fastener, channel or angle clamp with an aperture through which a screw fastener or snap interlocking wedge secures the gasket holder to the mullion. The retainer may be a retainer-cover of the front corner cavity combined in one element. Installation of the retainer secures the gasket holder to the mullion and applies pressure on an end of the panel gasket or the overlapping aligned ends of the panel gasket and the mullion gasket.

摘要:
The present invention provides a system, method and apparatus for producing fire rated doors having added strength, better finishing and low cost manufacturing flexibility. The fire rated doors are made from two panels “sandwiched” together. An optional interior layer (e.g., fire resistant material, lead sheeting, steel or Kevlar) can be added between the door panels for various purposes. Splines, stiles or sticks are inserted in longitudinal channels in the door panels to provide assistance in aligning the door panels and greater hardware holding strength. An intumescent banding material concealed by a banding material around the perimeter of the door seals the door within its frame during a fire. The door design and the automated manufacturing process provide greater design choice, reduced cost and faster fabrication.

An intumescent strip includes a first material layer and an opposing second material layer. A third material layer, formed from an intumescent material, is positioned between the first and second layers. The intumescent material includes a combination of intumescent particles suspended within a thermoplastic material. The intumescent particles have an activation temperature and are expandable when exposed to temperatures above the activation temperature. The thermoplastic material has a melting temperature that is lower than the activation temperature.
