摘要:
A composite product includes gypsum in an amount of 60 to 90% by weight, fibers in an amount of 1.5 to 26% by weight substantially homogeneously distributed through the composite, and a rheology-modifying agent in an amount of 0.5 to 6% by weight. The composite is caused or allowed to cure to form a cured composite. The cured composite is a fire resistant component used in a fire-rated door core, a fire-rated door or a fire-rated building panel. The fire resistant component may include a building panel, a door panel, a door core, a door rail, a door stile, a door lock block, a door border, or a door insert.
摘要:
A process for making a door structure and particularly a fibrous panel member for a subdoor structure. The process includes mixing a porous fiber material with a MDI adhesive. The fiber construct is compressed between a pair of porous belts. Steam and heat are applied to the compressed construct to form a bound flexible constructing material. The material is then placed within a door structure to form a fire resistant door.

This invention provides a fire-resistant reinforcement structure which facilitates work for improving fire resistance of architectural members such as pipes, a door, and a sash, a fire-resistant reinforcement architectural member, and a fire-resistant reinforcement method for an architectural member.A fire-resistant reinforcement structure is formed by pouring a thermally expandable fire-resistant material into a gap in and/or the interior of an architectural member, and characterized in that the viscosity of the thermally expandable heat-resistant material at 25° C. before the thermally expandable fire-resistant material is poured into the gap in and/or the interior of the architectural member is in the range of 1,000-100,000 mPa·s, and the thermally expandable fire-resistant material loses fluidity at 25° C. after being poured into the gap in and/or the interior of the architectural member.

The present disclosure includes a prehung fire door unit with one or two swing door leaf or leaves which unit is intended to be mounted in an opening made in a stonework construction, rising up substantially vertically in a building, the prehung door unit consisting of a fixed frame and at least one door leaf, the fixed frame being able to be fitted, at least in part, into a recess made in the opening and is made of an assembly of profiled elements fitted end to end and each made from an elongate flat element made of rigid material having temperature and fire resistance properties and that can be applied, either directly or indirectly, against at least one of the closed end faces of the recess so as to create, in the closed end of the recess, an additional finishing and/or supporting thickness for each door leaf.
摘要:
A door core includes a first major surface having one or more first recesses, a second major surface opposite to the first major surface, and fire retardant material such as intumescent material applied to the first recesses and no more than about 20 percent by surface area of a remainder of the first major surface excluding the first recesses. A door skin includes an interior surface, an exterior surface, at least one contoured panel portion establishing a protrusion extending on the interior surface and an opposite depression extending into the exterior surface, and fire retardant material such as intumescent material applied to at least one of the protrusion or the depression and no more than about 20 percent by surface area of the remainders of the interior surface excluding the protrusion and the exterior surface excluding the depression. Doors including the cores and/or door skins are also provided.

A prehung fire door unit with one or two swing door leaf or leaves intended to be mounted in an opening made in a stonework construction, rising up substantially vertically in a building. The prehung door unit includes a fixed frame and at least one door leaf, the fixed frame being able to be fitted, at least in part, into a recess made in the opening. The prehung door unit made of an assembly of profiled elements fitted end to end and each made from an elongate flat element made of rigid material having temperature and fire resistance properties and that can be applied, either directly or indirectly, against at least one of the closed end faces of the recess so as to create, in the closed end of the recess, an additional finishing and/or supporting thickness for each door leaf.

Provided are a fireproof door and a fireproof door frame. The fireproof door includes a water receiving part, a groove, a water expansion substance, an intake port, and a plurality of supply holes. The water receiving part holds water therein. The groove is formed along an edge of the fireproof door. The water expansion substance is inserted into the groove along the edge and expands when absorbing water to seal a gap between a door frame and the fireproof door. The intake port is disposed at a lower portion to supply water into the water receiving part. The plurality of supply holes is disposed along the groove between the water receiving part and the water expansion substance to supply water held in the water receiving part through the intake port to the water expansion substance.

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.
摘要:
A lockless metal fireproof door is pivotably mounted to an outer frame and includes two metal sheets, with a fireproof mechanism mounted in each metal sheet. A hinge is mounted to a bottom of the lockless metal fireproof door for automatically returning the lockless metal fireproof door, with a gap provided between each metal sheet and the outer frame. The lockless metal fireproof door can be moved to a position and retained in the position by the ground hinge. The lockless metal fireproof door is positioned by a weight thereof after the lockless metal fireproof door reaches the position. The lockless metal fireproof door expands in a lateral direction to tightly press against the outer frame if a side of the lockless metal fireproof door is subjected to heat.
