Disclosed is a water resistant joint sealing system comprising a coiled, coated precompressed core material. In one embodiment, the joint sealing system includes a fire retardant material put into the core material. In one embodiment, the fire retardant material forms a layer in, or between portions of material of, the core material.

A fire-shielding U-shaped outer frame element adapted for supporting a side of at least one wall element in a wall construction, said outer frame element being elongate and comprising a bottom part and a first side flange and a second side flange extending at an angle to the bottom part, interior surfaces of the side flanges being adapted for extending along exterior surfaces of the wall element. The outer frame element (1) comprises a plurality of perforations (15) and a first elongate strip (16) of a material having thermal shielding properties and being arranged on a surface of the first and/or second side flange (13, 14) of the outer frame element (1) so as to shield the wall element from heat from a fire. A set of parts include an outer frame element and a fastenings means for use between wall elements when making a wall construction.

A fire-resistant construction panel (10) includes a structural panel (12) as the web component of an I-joist (24) having an exposed surface (14) and a magnesium oxide board (18) covering the exposed surface (14). Alternately, the fire-resistant construction panel (10′) includes a load-resistant magnesium oxide board (30) being a structural element as the web of an I-joist (24′).

System for assisting in reducing the spread of fire between adjacent rooms in a building proximate to the ceiling thereof includes an elongated header track, at least one elongated filler constructed at least partially of compressible or elastic material and at least one fire-blocker constructed at least partially of fire retarding material.

A multi-layered inflammable wood material A for use as a building material includes a support wood material part 1 for supporting load, an inner inflammable wood material part 2a attached to a periphery of the support wood material part 1, and an outer inflammable wood material part 2b attached to a periphery of the inner inflammable wood material part 2a, wherein the inner inflammable wood material part 2a and the outer inflammable wood material part 2b both contain therein an inflammable agent, and an amount of the inflammable agent contained in the inner inflammable wood material part 2a is smaller than an amount of the inflammable agent contained in the outer inflammable wood material part 2b.

The present disclosure relates to a pole shield for extending around a pole structure. The pole shield comprises one or more than one sheet of composite material forming a hollow structure having an open first end and an opposed open second end. The sheet or sheets of composite material comprise from about 50% to about 80% by weight of a reinforcement impregnated with about 20% to about 50% of a polyurethane resin composition comprising a combination of a polyol component and a polyisocyanate component. Two or more pole shields may be stacked one on top of the other to form a pole shield structure which extends the height of protection of the pole structure. The pole shield can be used for protecting a pole structure from damage, such as from fire, rain, wind, sand, ice, pests, moisture or electrical. The pole shield may also be used to provide structural support to a pole structure.

Provided is a multi-layered reinforced wood material which is excellent in fire resistance, has extremely small damages on a support wood material part, and is also excellent in strength. The present invention is directed to a multi-layered reinforced wood material A for use as a building material, the multi-layered reinforced wood material A including a support wood material part 1 for supporting load, a sheet part 3 attached to the periphery of the support wood material part 1, an inflammable wood material part 2 attached outside the sheet part 3 so as not to expose the sheet part 3, wherein the inflammable wood material part 1 is made of a wood material containing therein an inflammable agent, and the sheet part 3 is made of a fiber reinforced plastic.

An elongated structural barrier is provided including a base, a first panel extending upward from the base, a first sealer wall extending downward and transversely to the base, a second panel joined with the first panel and extending upwardly, a lower wedge extending upward from the base adjacent the first sealer wall, and a core compartment bounded by the lower wedge and the panels, with an open face defined above the lower wedge and offering a view into the core compartment. The lower wedge can include a flange to produce a first cavity of the compartment, in which an intumescent core can be positioned and configured to expand into a second cavity of the compartment when it swells. A second flange can oppose the first flange to further secure the core in the first cavity, and can form a bloom gap therebetween. A related method of use also is provided.

Described herein is a corrugated intumescent composite structure comprising at least one metal mesh layer secured on or in an intumescent material, wherein the composite structure comprises a plurality of alternating flanges and ribs. In one embodiment, the corrugated intumescent composite structure disposed onto a metal decking for fire protection.

Embodiments of a leno weave mesh of the present invention generally include a plurality of high-temperature weft yarns, high-temperature warp yarns, and low melting point warp yarns; wherein each low melting point warp yarn is intertwined with a high-temperature warp yarn, each intertwined pair of warp yarns is positioned such that the low melting point warp yarn and high-temperature warp yarn are disposed alternatingly on either side of the woven mesh at intersections of the weft and warp yarns, and the woven mesh is heated whereby the surfaces of the low melting point warp yarns adhere to the surface of the high-temperature warp yarns and said high-temperature weft yarns at contact points there between. An intumescent coating system employing embodiments of the mesh, and a method of providing thermal protection to a substrate utilizing the intumescent coating system, are also provided.
